DETAILED DESCRIPTION

[0031] The present invention provides Figures 1 to 8 A clamping tool for forklift casting welding processing shown in the figure includes a control member 1 and a rotating shaft 2. Two control members 1 are provided. The two control members 1 form an opening and closing structure through the rotating shaft 2, and an elastic member (not shown in the figure) is provided on the rotating shaft 2, such as a torsion spring, etc., to achieve the resetting of the two control members 1, and one of the control members 1 can be connected to an external welding clamp through a cable.

[0032] The control member 1 includes a gripping portion 25 and a clamping portion 26. The gripping portion 25 is for the operator to grip, thereby achieving control of the clamping tool. When in use, an insulating rubber sleeve is provided on the outside of the gripping portion 25, and an anti-skid texture is provided to avoid slipping, while achieving an insulating effect and improving the safety of the operation; the clamping portion 26 is close to the body electrode of the electric welding machine.

[0033] One end of the clamping portion 26 away from the holding portion 25 is fixedly connected with a clamp 3. The two clamps 3 are provided with arc grooves 4 on their sides close to each other. The two arc grooves 4 cooperate with each other and are attached to the outside of the electrode.

[0034] During actual use, the operator holds the two gripping parts 25 with one hand and squeezes them, and the two gripping parts 25 move together. With the cooperation of the rotating shaft 2 and the clamping part 26, the two clamps 3 open in a V shape, and then the two arc grooves 4 are made to correspond to the electrode. The operator releases the two gripping parts 25, and the two clamps 3 are reset and moved together, and the arc groove 4 fits on the outside of the electrode to complete the connection with the electrode.

[0035] Considering that the control member 1, the clamp 3, the arc groove 4 and other structures are only used to clamp the electrodes, during use, the connected cables are often pulled and rotated by the welding clamp, especially the forklift casting has a large welding area, which may easily cause the control member 1, the clamp 3, the arc groove 4 and other structures to fall off the electrodes due to the force generated by the pulling or rotation, thereby reducing the efficiency of the forklift casting welding process. In order to ensure the stability of the clamping, a U-shaped frame 9 is provided on the outside of the control member 1, and sliding channels 10 are provided on both sides of the U-shaped frame 9. The two ends of the rotating shaft 2 are respectively slidably connected to the inside of the two sliding channels 10, and the outer diameters of the two ends of the rotating shaft 2 are larger than the outer diameters 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] The two gripping parts 25 are fixedly connected to a fixed seat 5 on the side close to each other, and a rotating plate 6 is rotatably connected to the fixed seat 5. The rotating plate 6 is tilted, and the end of the rotating plate 6 away from the fixed seat 5 is tilted toward the rotating shaft 2. The ends of the two rotating plates 6 close to each other are rotatably connected through a rotating block 7, and 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 gripping parts 25 with one hand and squeezes them, the two gripping parts 25 move closer together. Figure 1 , the rotating plate 6 at the upper end position swings clockwise, and the rotating plate 6 at the lower end position swings counterclockwise, so that the rotating seat 8 moves toward the rotating shaft 2, driving the U-shaped frame 9 to move synchronously; when the operator releases the two gripping parts 25, the two gripping parts 25 move together and open, referring to Figure 1 The rotating plate 6 at the upper end position swings counterclockwise, and the rotating plate 6 at the lower end position 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] The provision of structures such as the rotating plate 6 and the rotating seat 8, and the coordination of the rotating shaft 2 and the sliding channel 10 can improve the overall structural stability of the clamping tool.

[0039] One end of the rotating shaft 2 is provided with a fastening assembly 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 gripping parts 25 is also fixed.

[0040] In the specific setting, the fastening assembly includes a threaded hole 11, a bolt 12 and a round sleeve 13. The threaded hole 11 is provided on the rotating shaft 2, the bolt 12 is threadedly connected to the threaded hole 11, the round sleeve 13 is provided on the bolt 12, and the round sleeve 13 is abutted against the U-shaped frame 9. When the bolt 12 is rotated, the round sleeve 13 is driven to move toward the U-shaped frame 9, and the round sleeve 13 is pressed on the outer wall of the U-shaped frame 9 to position the U-shaped frame 9, thereby positioning the rotating seat 8, so that the angle between the two clamps 3 is fixed. During the welding process, when the connected cable is pulled and rotated by the electric welding clamp, the clamping tool is not easy to fall off.

[0041] Moreover, the friction coefficient between the threaded hole 11 and the bolt 12 is appropriate, and random rotation will not occur. In actual use, a structure such as a latch can be provided to position the bolt 12.

[0042] When the gripping portion 25 needs to be reset, the bolt 12 is rotated in the opposite direction to release the squeezing of the U-shaped frame 9 , so that the U-shaped frame 9 can move on the rotating shaft 2 , thereby resetting the gripping portion 25 .

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

[0044] In actual use, the bolt 12 is rotated in the opposite direction to release the squeezing of the U-shaped frame 9, and the U-shaped frame 9 can move on the rotating shaft 2. When the operator holds the two gripping parts 25 with one hand and squeezes them, the two gripping parts 25 move closer together. Figure 1 , the rotating plate 6 at the upper end position swings clockwise, and the rotating plate 6 at the lower end position swings counterclockwise, so that the rotating seat 8 moves toward 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 clamps 3 open in a V shape, and then the two arc grooves 4 correspond to the electrode. The operator loosens the two gripping parts 25, and the two clamps 3 are reset and close together, and the arc grooves 4 fit the outside of the electrode to complete the connection with the electrode. Then, the bolt 12 is rotated to drive the round sleeve 13 to move toward the U-shaped frame 9. The round sleeve 13 is squeezed on the outer wall of the U-shaped frame 9 to position the U-shaped frame 9, thereby positioning the rotating seat 8, so that the angle between the two gripping parts 25 is fixed at the same time.

[0045] Considering that when the two clamps 3 are reset and close together, the arc groove 4 fits on the outside of the electrode, especially when the size of the butt joint part is large, there is a certain gap between the two clamps 3 at a position far away from the clamping part 26, and there is a risk of the clamping tool falling off. In order to improve the stability of clamping, a slide groove 14 is provided on the inner wall of the arc groove 4, and the slide groove 14 is located at one end of the arc groove 4 far away from the clamping part 26. An arc plate 15 is slidably provided inside the slide groove 14. When the two clamps 3 are opened and clamped at the electrode, the arc plate 15 extends from the inside of the slide groove 14 and fits on the outside of the electrode. Arc slideways 16 are provided on the outer walls of both sides of the clamps 3. The arc slideways 16 are connected to the corresponding slide grooves 14. The inside of the arc slideway 16 is slidably connected to a slide rod 17, and the slide rod 17 is fixedly connected to the corresponding arc plate 15. The arc slideway 16 and the slide rod 17 are provided to improve the sliding stability of the arc plate 15.

[0046] One end of the slide bar 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 slide bar 17 is rotatably connected to a round bar 18 , and the round bar 18 is fixedly connected to the U-shaped frame 9 .

[0047] In actual use, when the operator holds the two gripping parts 25 with one hand and squeezes them, the two gripping parts 25 move closer, so that the rotating seat 8 moves toward the rotating shaft 2, driving the U-shaped frame 9 to move synchronously. When the U-shaped frame 9 moves, the corresponding sliding rod 17 is pushed through the arc bar 19, and the sliding rod 17 slides inside the arc slide 16. The arc plate 15 extends from the inside of the slide groove 14 and fits onto the outside of the electrode, thereby improving the stability of clamping and ensuring the effect of the forklift casting welding processing.

[0048] When the U-shaped frame 9 is reset, the arc strips 19, the arc plates 15 and other structures are driven to reset synchronously.

[0049] In order to further improve the clamping stability, both sides of the U-shaped frame 9 are fixedly connected with a protrusion 21, which is located at one end of the U-shaped frame 9 close to the clamp 3, and the end of the clamp 3 away from the U-shaped frame 9 is provided with a square groove 20, and a sliding column 22 is slidably arranged inside the square groove 20, and the sliding column 22 extends to the outside of the square groove 20. A spring 24 is arranged inside the square groove 20, and 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. The end of the sliding column 22 located outside the square groove 20 is fixedly connected with a positioning frame 23, and the positioning frame 23 is V-shaped and suitable for electrodes of different sizes.

[0050] When the operator holds the two gripping parts 25 with one hand and squeezes them, the two gripping parts 25 move together, so that the rotating seat 8 moves toward the rotating shaft 2, driving the U-shaped frame 9, the protrusion 21, the positioning frame 23 and other structures to move synchronously, and the positioning frame 23 fits the outside of the electrode. Under the squeeze, the sliding column 22 is retracted to the inside of the square groove 20, and the restoring elastic force of the spring 24 makes the positioning frame 23 fit tightly on the electrode. The positioning frame 23, the two arc plates 15, and the two clamps 3 cooperate to form clamping limits in different directions on the outside of the electrode, improve the stability of the clamping tooling and the electrode, and thus ensure the efficiency of the forklift casting welding process.
