1. There are many reasons for the overturning motor of the worktable. We analyze the following one by one:

(1) The contact of the contactor is not in good contact, the phase is missing, and the coil is faulty. This way the contactor contacts can be handled and the contactor replaced if necessary.

(2) The thermal relay fails or malfunctions. Just replace the thermal relay or reset it.

(3) If the button fails, repair or replace the button.

(4) The motor holding brake is not opened or the motor load terminal is loose, and the contact is not good: check the motor holding brake device and fasten the load terminal.

2. After pressing the button, if there is no lifting action or one-way action, it may be because the limit machine is stuck or the contact is faulty, so it is good to replace the limit. It may also be that the contact of the button is not good or the return spring of the button is damaged. It is good to repair it. If it cannot be repaired, replace the button. It is also possible that the thermal relay setting current is small and malfunctioning or the thermal relay is faulty. You can adjust the setting current or replace the thermal relay. If the motor does not move, there is a buzzing sound, the contactor is out of phase, and the load terminals are not in good contact. If such a situation occurs, check the contactor and replace the contactor if necessary, and tighten the load terminals.

However, there are also three types of welding positioner structures. One is the single-turn type, which is widely used. To meet the needs of different workpiece clamping, there are also three basic types, a vertical type, a horizontal type, and a double-seat type. The double seat is also divided into two types: fixed tailstock and movable tailstock. There is also a double rotary type, which is mainly to adapt to the clamping needs of different workpieces and to consider the reasonable force of the structure. There are also three basic types, L type, C type, and H type. There is also a tip-and-turn type, which also has a different structural design.

Parts of welding positioner

The main structure of the welding positioner is a rotary head, a positioner, and a controller. The rotating speed of the rotary head can be adjusted by itself, with an independent speed control circuit, and the DIP switch can directly set the initial value of the weld length. The inclination angle can be adjusted according to the needs of the weldment, and the welding torch can also be lifted pneumatically. The motor of the welding positioner drives the multi-stage worm gear reducer to drive and realizes the rotation of the worktable through the main shaft. It has the characteristics of stable operation, and the rotation speed is 0.1 ~ 3r/min. The handwheel is driven by a worm and a worm wheel, thereby driving the worktable to turn bricks within a range of 120°. (displayed by the dial), the turning torque is large, the positioning is reliable, and it has a self-locking function.

The products of the machine tool industry are mainly metal cutting machine tool products, forging machinery products, foundry machinery products, woodworking machine tool products, and tools. Among them, metal cutting machine tools, forging machinery, and casting welding displacement machine products are the main fields of displacement machine application in the machine tool industry.

Welding positioner chuck

The welding positioner has gradually developed into the main technology of the machine tool industry, and its main performances are as follows.

(1) Some key enterprises have built welding factories or metal structure factories of a certain scale and established a complete welding management system. Absorb and digest the welding technical standards of imported products, implement professional standards, and formulate enterprise standards.

(2) Improve the welding process flow, and develop from single processing technology to a series of new comprehensive engineering technologies such as raw material pretreatment, cutting, forming, welding, post-welding inspection, and post-welding treatment.

(3) The application of numerical control cutting and computer programming routine technology has changed the blanking technology of traditional manual cutting and reduced mechanical processing.

(4) The new technology of promoting vibration aging is realized, the residual stress of the welded structure is reduced, the purpose of homogenization is achieved, the deformation of welded parts is reduced, and the accuracy is stabilized.

Welding positioner chuck

The welding positioner can ensure the smooth progress of the welding process when it is used. It can not only play a good auxiliary role in welding but also have a good effect in later use. This credit is mainly due to the welding positioner. When using, there is an important accessory---welding chuck. The application of the chuck can ensure the normal use of the welding positioner. Therefore, in the later maintenance, attention should not only be paid to the maintenance of the welding positioner, but also the maintenance of the chuck. maintain:

1. After the chuck is used, it is necessary to use tools such as air guns to clean the welding chuck body and slide the surface of the welding positioner. As a result, good accuracy can be ensured even after using the chuck for a long time, so regular lubrication of the chuck is important.

2. Apply molybdenum disulfide grease (black) at least once a day, and pump the grease into the grease nozzle of the welding chuck until the grease flows from the jaw surface or the inner hole of the welding chuck (the inner hole protective cover). and connecting nut) until it overflows.

3. To prevent rust inside the chuck, the clamping force will drop, and the workpiece cannot be clamped, so use cutting oil with anti-rust effect, and the use of cutting oil can prevent the inside of the chuck from rusting.

4. After the work is completed, it is necessary to clean the main body of the welding chuck and the slide surface with an air gun, etc.

5. The chuck should be removed and cleaned at least every 6 months, keep the bending surface of the chuck claw clean and lubricate it to prolong the life of the chuck.

6. Check all parts for cracks and wear, and clean the cast iron at least once every two months. If there is serious damage, it needs to be replaced with new products immediately.

7. Each workpiece needs to use different clamping methods, and using it to clamp irregular workpieces will damage the welding chuck.

8. In the case of abnormal chuck pressure, if the chuck is clamped with high pressure, the life of the chuck will be reduced. Therefore, if the gap of the chuck is found to be too large, it is necessary to replace the new chuck immediately.

Welding positioner chuck

When the chuck of the welding positioner is used, it is necessary to pay attention to regular maintenance to prevent the phenomenon that affects the overall quality. In the later maintenance, it is necessary to ensure that the quality of the chuck is not damaged, to ensure a good maintenance effect.
