An arc plate is slidably arranged inside the sliding groove. When the two clamping pieces are opened and clamped at the electrode, the arc plate extends out from the inside of the sliding groove and fits outside the electrode;

[0008] A U-shaped frame is arranged outside the control member. Sliding channels are provided on both sides of the U-shaped frame. Both ends of the rotating shaft are respectively slidably connected inside the two sliding channels. When the two holding parts approach each other, the U-shaped frame moves towards the clamping member. One end of the rotating shaft is provided with a fastening assembly for fixing the position of the U-shaped frame. When the position of the U-shaped frame is fixed, the angle between the two holding parts is fixed simultaneously.

[0009] Preferably, fixed seats are fixedly connected to the sides of the two holding parts that approach each other. A rotating plate is rotatably connected to the fixed seat.

[0031] The present invention provides a clamping tooling for welding and processing of forklift castings as shown in Figures 1 to 8 which includes a control member 1 and a rotating shaft 2. There are two control members 1, and the two control members 1 form an opening and closing structure through the rotating shaft 2. An elastic member (not shown in the figure), such as a torsion spring, etc., is arranged on the rotating shaft 2 to realize the reset of the two control members 1, and one of the control members 1 can be connected to an external electric welding clamp through a cable.

[0032] The control member 1 includes a holding part 25 and a clamping part 26. The holding part 25 is for an operator to hold, so as to realize the control of the clamping tooling. During specific use, an insulating rubber sleeve is arranged outside the holding part 25, and anti-slip textures are arranged to avoid slipping, and at the same time achieve the insulating effect and improve the safety of operation; the clamping part 26 is close to the body electrode of the electric welding machine.

[0033] One end of the clamping part 26 far from the holding part 25 is fixedly connected with a clamping member 3. Arc grooves 4 are opened on one side of the two clamping members 3 close to each other. The two arc grooves 4 cooperate with each other, and the arc grooves 4 are attached to the outside of the electrode.

[0034] During actual use, an operator holds the two holding parts 25 with one hand and squeezes them. The two holding parts 25 approach each other. Under the cooperation of the rotating shaft 2 and the clamping part 26, the two clamping members 3 are opened in a V shape. Then, the two arc grooves 4 are aligned with the electrode. The operator releases the two holding parts 25, and the two clamping members 3 reset and approach each other, and the arc grooves 4 are attached to the outside of the electrode to complete the connection with the electrode.

[0035] Considering that only through the cooperation of structures such as the control member 1, the clamping member 3 and the arc groove 4, it is clamped at the electrode. During the use process, the connected cable is often pulled and rotated by the electric welding clamp. Especially when the welding area of the forklift casting is large, it is easy to cause the structures such as the control member 1, the clamping member 3 and the arc groove 4 to fall off from the electrode due to the force generated by pulling or rotating, reducing the efficiency of welding and processing of the forklift casting. To ensure the clamping stability, a U-shaped frame 9 is arranged outside the control member 1. Sliding channels 10 are opened on both sides of the U-shaped frame 9. The two ends of the rotating shaft 2 are respectively slidably connected inside the two sliding channels 10, and the outer diameter of the two ends of the rotating shaft 2 is larger than the outer diameter of other positions (refer to Figure 7), to ensure the stability of the connection between the U-shaped frame 9 and the rotating shaft 2.

[0036] On one side where the two holding parts 25 are close to each other, a fixed seat 5 is fixedly connected. A rotating plate 6 is rotatably connected to the fixed seat 5. The rotating plate 6 is inclined, and one end of the rotating plate 6 away from the fixed seat 5 is inclined towards the rotating shaft 2. The two ends of the two rotating plates 6 close to each other are rotatably connected through a rotating block 7. A rotating seat 8 is rotatably connected to the rotating block 7. The U-shaped frame 9 is fixedly connected to the rotating seat 8.

[0037] When the operator holds the two holding parts 25 with one hand and squeezes them, the two holding parts 25 move closer. Referring to Figure 1 , the rotating plate 6 at the upper end swings clockwise, and the rotating plate 6 at the lower end swings counterclockwise, so that the rotating seat 8 moves towards the rotating shaft 2, driving the U-shaped frame 9 to move synchronously; when the operator releases the two holding parts 25, the two holding parts 25 move closer and open. Referring to Figure 1 , the rotating plate 6 at the upper end swings counterclockwise, and the rotating plate 6 at the lower end swings clockwise, so that the rotating seat 8 moves away from the rotating shaft 2, driving the U-shaped frame 9 to move synchronously.

[0038] By setting structures such as the rotating plate 6 and the rotating seat 8, and the cooperation between the rotating shaft 2 and the sliding channel 10, the overall structural stability of the clamping tooling can be improved.

[0039] One end of the rotating shaft 2 is provided with a fastening component for fixing the position of the U-shaped frame 9, so that when the position of the U-shaped frame 9 is fixed, the angle between the two holding parts 25 is fixed at the same time.

[0040] Specifically, the fastening component includes a threaded hole 11, a bolt 12 and a round sleeve 13. The threaded hole 11 is opened on the rotating shaft 2. The bolt 12 is threadedly connected to the threaded hole 11. The round sleeve 13 is arranged on the bolt 12. The round sleeve 13 is in abutting cooperation with the U-shaped frame 9. When the bolt 12 is rotated, the round sleeve 13 is driven to move towards the U-shaped frame 9. The round sleeve 13 presses against the outer wall of the U-shaped frame 9 to position the U-shaped frame 9, thereby positioning the rotating seat 8 and fixing the angle between the two clamping parts 3. During the welding process, when the connected cable is pulled and rotated by the electric welding clamp, the clamping tooling is not easily dropped.

[0041] And the friction coefficient between the threaded hole 11 and the bolt 12 is appropriate, and there will be no random rotation. In actual use, structures such as a pin can also be set to position the bolt 12.

[0042] When the holding part 25 needs to be reset, the bolt 12 is rotated in the reverse direction to release the extrusion of the U-shaped frame 9. The U-shaped frame 9 can move on the rotating shaft 2, so that the holding part 25 is reset.

[0043] The outer diameter of the round sleeve 13 is larger than the width of the sliding channel 10, so that the round sleeve 13 will not pass through the inside of the sliding channel 10.

[0044] In actual use, turn the bolt 12 in the reverse direction to release the extrusion on the U-shaped frame 9, and the U-shaped frame 9 can move on the rotating shaft 2. When the operator holds the two holding parts 25 with one hand and squeezes them, the two holding parts 25 approach each other. Refer to Figure 1 , the rotating plate 6 at the upper end swings clockwise, and the rotating plate 6 at the lower end swings counterclockwise, so that the rotating seat 8 moves towards the rotating shaft 2, driving the U-shaped frame 9 to move synchronously. With the cooperation of the rotating shaft 2 and the clamping part 26, the two clamping parts 3 are opened in a V shape, and then the two arc grooves 4 are aligned with the electrode. The operator releases the two holding parts 25, and the two clamping parts 3 reset and approach each other, and the arc grooves 4 fit on the outside of the electrode to complete the connection with the electrode. Then turn the bolt 12 to drive the round sleeve 13 to move towards the U-shaped frame 9. The round sleeve 13 presses against the outer wall of the U-shaped frame 9 to position the U-shaped frame 9, thereby positioning the rotating seat 8 and fixing the angle between the two holding parts 25 at the same time.

[0045] Considering that when the two clamping parts 3 reset and approach each other, and the arc grooves 4 fit on the outside of the electrode, especially for an electrode with a relatively large size at the docking part, there is a certain gap between the two clamping parts 3 at the position far from the clamping part 26, and there is a risk of the clamping tooling falling off. To improve the clamping stability, a sliding groove 14 is opened on the inner wall of the arc groove 4, and the sliding groove 14 is located at one end of the arc groove 4 far from the clamping part 26. An arc plate 15 is slidably arranged inside the sliding groove 14. When the two clamping parts 3 are opened and clamped on the electrode, the arc plate 15 extends out from the inside of the sliding groove 14 and fits on the outside of the electrode. Arc-shaped sliding grooves 16 are opened on the outer walls on both sides of the clamping part 3. The arc-shaped sliding grooves 16 communicate with the corresponding sliding grooves 14, and a sliding rod 17 is slidably connected inside the arc-shaped sliding grooves 16. The sliding rod 17 is fixedly connected to the corresponding arc plate 15. The arc-shaped sliding groove 16 and the sliding rod 17 are provided to improve the sliding stability of the arc plate 15.

[0046] One end of the sliding rod 17 away from the arc plate 15 is rotatably connected to an arc bar 19, and one end of the arc bar 19 away from the sliding rod 17 is rotatably connected to a round rod 18, and the round rod 18 is fixedly connected to the U-shaped frame 9.

[0047] In actual use, when the operator holds the two holding parts 25 with one hand and squeezes them, the two holding parts 25 approach each other, so that the rotating seat 8 moves towards the rotating shaft 2, driving the U-shaped frame 9 to move synchronously. When the U-shaped frame 9 moves, it will push the corresponding sliding rod 17 through the arc bar 19. The sliding rod 17 slides inside the arc-shaped sliding groove 16, and the arc plate 15 extends out from the inside of the sliding groove 14 and fits on the outside of the electrode, improving the clamping stability and ensuring the effect of the welding process of the forklift casting.

[0048] When the U-shaped frame 9 resets, it drives the structures such as the arc bar 19 and the arc plate 15 to reset synchronously.

[0049] To further improve the clamping stability, convex blocks 21 are fixedly connected to both sides of the U-shaped frame 9. The convex blocks 21 are located at one end of the U-shaped frame 9 close to the clamping member 3. A square groove 20 is formed at one end of the clamping member 3 away from the U-shaped frame 9. A sliding column 22 is slidably arranged inside the square groove 20. The sliding column 22 extends to the outside of the square groove 20. A spring 24 is arranged inside the square groove 20. One end of the spring 24 is fixedly connected to the sliding column 22, and the other end of the spring 24 is fixedly connected to the inner wall of the square groove 20. One end of the sliding column 22 located outside the square groove 20 is fixedly connected to a positioning frame 23. The positioning frame 23 is V-shaped and is suitable for electrodes of different sizes.

[0050] When the operator holds the two holding parts 25 with one hand and squeezes them, the two holding parts 25 approach each other, causing the swivel base 8 to move towards the rotating shaft 2, driving the synchronous movement of structures such as the U-shaped frame 9, the convex blocks 21, and the positioning frame 23. The positioning frame 23 fits against the outside of the electrode. Under the squeezing action, the sliding column 22 retracts into the square groove 20, and the restoring elastic force of the spring 24 causes the positioning frame 23 to closely fit against the electrode. The cooperation of the positioning frame 23, the two arc plates 15, and the two clamping members 3 forms clamping limits in different directions on the outside of the electrode, improving the stability of the docking between the clamping tooling and the electrode, thereby ensuring the efficiency of the welding process of the forklift casting.
