[0021] The technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-4 As shown, the controllable clamping distance automotive welding fixture provided in this embodiment includes a support plate 1. Both ends of the upper surface of the support plate 1 are equipped with detachable welding clamping structures 2. The detachable welding clamping structures 2 are composed of two opposing jaws 3. The jaws 3 include a fixing block 4, a first shaft 5 disposed on the fixing block 4, a clamping rod 6 rotatably sleeved on the first shaft 5, a clamping block 7 installed at one end of the clamping rod 6, a connecting rod 8 installed at the other end of the clamping rod 6, and a hydraulic rod 9 hinged to the end of the connecting rod 8. The hydraulic rod 9 is fixed to the upper surface of the support plate 1 by a connecting seat 10. The support plate 1 is used to support and fix the detachable welding clamping structure 2; the detachable welding clamping structure 2 is used to fix and clamp the automotive panel to be welded, preventing the panel from shaking or shifting during welding, and different clamps 3 can be replaced according to the size of the panel; the clamps 3 are used to fix and clamp the panel to be welded; the fixing block 4 is used to support and fix the clamps 3; the first shaft 5 is used to allow the clamping rod 6 to be rotatably sleeved on the upper surface of the fixing block 4; the clamping rod 6 is used to transmit clamping force to fix and clamp the panel to be welded; the clamping block 7 is used to fit and clamp the panel to be welded; the connecting rod 8 is used to connect the clamping rod 6 to the hydraulic rod 9; the hydraulic rod 9 is used to provide clamping driving force for the clamps 3; the connecting seat 10 is used to support and fix the hydraulic rod 9.

[0023] The upper surface of the clamping rod 6 is provided with a second shaft 11, and the clamping block 7 is rotatably sleeved on the second shaft 11. The top end of the second shaft 11 is provided with a first limiting and fixing cap 12, which is fixed to the second shaft 11 by bolts. This makes the first limiting and fixing cap 12 tightly fixed to the second shaft 11. The second shaft 11 allows the clamping block 7 to be rotatably sleeved on the upper surface of the clamping rod 6. The first limiting and fixing cap 12 is used to limit and fix the clamping block 7, so that the clamping block 7 can rotate on the second shaft 11 but will not wobble up and down.

[0024] The first shaft 5 is fitted with a second limiting and fixing cap 13 at its top end. The second limiting and fixing cap 13 is fixed to the first shaft 5 by bolts, so that the second limiting and fixing cap 13 is tightly fixed to the first shaft 5. The end of the hydraulic rod 9 is hinged to the connecting seat 10, so that the hydraulic rod 9 can adapt to the changing angles during extension and retraction. The second limiting and fixing cap 13 is used to limit and fix the clamping rod 6, so that the clamping rod 6 can rotate on the first shaft 5 but will not sway up and down.

[0025] The clamping rod 6 and the connecting rod 8 are connected by a movable locking block 14. The movable locking block 14 includes a first locking block 15 connected to the connecting rod 8 and a second locking block 16 connected to the clamping rod 6. The movable locking block 14 is used to separate or fix the clamping rod 6 and the connecting rod 8. When the clamping rod 6 and the connecting rod 8 are separated, the clamping rod 6 can be replaced.

[0026] When the first locking block 15 and the second locking block 16 engage with each other, they can be locked together to prevent the gripper 3 from shaking at the interface during the clamping movement. At the same time, the engagement position of the first locking block 15 and the second locking block 16 can be adjusted to increase or decrease the angle between the clamping rod 6 and the connecting rod 8, thereby improving the clamping effect of the gripper 3. The first locking block 15 and the second locking block 16 are fixed together by bolts, so that the first locking block 15 and the second locking block 16 are tightly fixed together.

[0027] The extension end of the hydraulic rod 9 is provided with a sleeve block 17, and the side of the connecting rod 8 is provided with a square groove 18. A third shaft 19 is provided in the square groove 18 at the end of the connecting rod 8. The sleeve block 17 is rotatably sleeved on the third shaft 19. The sleeve block 17 makes the hydraulic rod 9 hinged to the third shaft 19 in the connecting rod 8. The square groove 18 is used to store the extended hydraulic rod 9 when it is extended.

[0028] The upper surface of the support plate 1 has several mounting slots 20. The fixing block 4 is fixed to the support plate 1 by bolts, so that the bolts can be inserted into the mounting slots 20 to fix the fixing block 4 to the upper surface of the support plate 1. This allows the detachable welding clamping structure 2 to be on the upper surface of the support plate 1. At the same time, the position of the detachable welding clamping structure 2 on the support plate 1 can be adjusted appropriately so that the gripper 3 can better position and clamp the welding plate.

[0029] Support legs 21 are provided at the corners of the lower surface of the support plate 1, and several support blocks 22 are symmetrically arranged on the upper surface of the support plate 1. Anti-slip grooves 23 are provided on the inner side of the clamping block 7. The support legs 21 are used to support the device, and the support blocks 22 are used to support the detachable welding clamping structure 2. At the same time, the welding debris can be pushed into the two adjacent support blocks 22 to prevent the debris from hindering the clamping movement of the detachable welding clamping structure 2. The anti-slip grooves 23 enable the clamping block 7 to firmly clamp the welding plate and prevent slippage during clamping.

[0030] like Figures 1-4 As shown, the principle of the controllable clamping distance automotive welding fixture provided in this embodiment is as follows: When using the device, first select the appropriate clamping jaws 3 according to the plate to be welded, then select the appropriate mounting slots 20 according to the plate to be welded, then fix the fixing block 4 to the support plate 1 with bolts and mounting slots 20, then sleeve the clamping rod 6 on the first shaft 5, and then cover the first limiting fixing cap 12 on the first shaft 5 and fix the first limiting fixing cap 12 on the first shaft 5 with bolts, ensuring that the clamping rod 6 can be positioned on the first shaft 5. Rotate upwards; then, place the clamping block 7 on the second shaft 11, cover the second limiting fixing cap 13 on the second shaft 11, and fix the second limiting fixing cap 13 on the second shaft 11 with bolts to ensure that the clamping block 7 can rotate on the second shaft 11; first, lift the connecting rod 8 upwards, then adjust the first locking block 15 at one end of the connecting rod 8 to a suitable angle and engage it with the second locking block 16 at one end of the clamping rod 6, and then fix and lock the engaged first locking block 15 and second locking block 16 with bolts to complete the installation;

[0031] After installation, the plates to be welded can be placed on the clamping rod 6. The hydraulic rod 9 will extend, and the four jaws 3 will retract inward at the same time to position and clamp the plates on the clamping rod 6. Then, the clamped plates can be welded. After welding, the hydraulic rod 9 will retract, causing the four jaws 3 to expand outward at the same time, and the welded plates on the clamping rod 6 can be removed.

[0032] The foregoing description illustrates and describes preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein. Any modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the protection scope of the appended claims.
