[0015] Compared with the prior art, the present invention provides a welding fixture with stable clamping, which has the following beneficial effects: 1.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] This invention provides, for example Figures 1-8The welding fixture shown includes a height adjustment sleeve 2, a fixed base 1 connected to the outer side of the lower end of the height adjustment sleeve 2, a height adjustment slide rod 3 slidably connected to the inner side of the upper end of the height adjustment sleeve 2, a directional adjustment head 4 rotatably connected to the upper end of the height adjustment slide rod 3, a connecting side rod 5 connected to the right end of the directional adjustment head 4, a corner head 6 rotatably connected to the right end of the connecting side rod 5, an angle head 7 rotatably connected to the right end of the angle head 6, a clamping frame 8 connected to the right end of the angle head 7, clamping screws 9 threadedly connected to the inner ends of both the front and rear ends of the clamping frame 8, clamping plates 10 rotatably connected to the inner ends of both clamping screws 9, and both clamping plates 10 are located inside the clamping frame 8 and are in contact with the inner wall of the left end of the clamping frame 8, and a locking slide 11 is connected to the lower end of the height adjustment slide rod 3. A sliding connection is installed inside the height adjustment sleeve 2. The directional adjustment head 4, connecting side rod 5, corner head 6, tilt head 7, and height locking slide 11 are equipped with linkage components. These linkage components fix the positions of the height adjustment sleeve 2 and height adjustment slide rod 3, the height adjustment slide rod 3 and directional adjustment head 4, the connecting side rod 5 and corner head 6, and the corner head 6 and tilt head 7. A height fixing component is installed between the height adjustment sleeve 2 and the height adjustment slide rod 3, fixing the height of the height adjustment slide rod 3. A directional component is installed between the height adjustment slide rod 3 and the directional adjustment head 4, fixing the direction of the connecting side rod 5 and the corner head 6. A shaft rotation angle fixing component is installed between the connecting side rod 5 and the corner head 6, fixing the clamping frame. The rotation angle on the axis of the corner head 6 is fixed. An axis tilt angle fixing component is provided between the corner head 6 and the tilt head 7. The included angle between the clamping frame 8 and the axis of the corner head 6 is fixed by the axis tilt angle fixing component. The height fixing component, orientation component, axis rotation angle fixing component and axis tilt angle fixing component are all connected to the linkage component and can be locked in an orderly manner by the linkage component. During the welding process of the workpiece, the workpiece is placed between the two clamping plates 10. By rotating the clamping screws 9 on both sides, the clamping plates 10 on both sides are driven to move towards the middle and clamp and fix the workpiece. The clamping surfaces of the two clamping plates 10 are provided with teeth to ensure clamping stability. At this time, the height adjustment slide rod 3 is used to adjust the clamp inside the upper end of the height adjustment sleeve 2. The height of the clamping frame 8 is adjusted and locked by a height-fixing component. The position of the clamping frame 8 is adjusted by rotating the directional turn head 4 at the upper end of the height-adjusting slide bar 3 and locked by a direction-orienting component. The rotation angle of the clamping frame 8 on the axis of the directional turn head 6 is adjusted by rotating the angular turn head 6 at the right end of the connecting side rod 5 and locked by an angle-fixing component. The angle between the clamping frame 8 and the axis of the directional turn head 6 is adjusted by rotating the tilt turn head 7 at the right end of the directional turn head 6 and locked by an angle-fixing component. Thus, the height, direction, axial rotation angle and axial tilt angle of the clamping frame 8 are adjusted and fixed, allowing the clamping frame 8 to quickly adjust and fix the position of the clamped workpiece in multiple directions, ensuring that the workpiece can be accurately welded to the welding position.
[0030] like Figures 2-4 As shown, the linkage assembly includes a main linkage shaft 13 and a side linkage rod 24. A locking handle 12 is rotatably connected to the upper end of the directional control head 4, and the lower end of the locking handle 12 is connected to the main linkage shaft 13. The lower end of the main linkage shaft 13 passes through the interior of the directional control head 4 and is rotatably connected to the upper end of the height adjustment slide rod 3. A main linkage screw 14 is threadedly connected to the lower end of the main linkage shaft 13. A telescopic pressure rod 15 is connected to the lower end of the main linkage screw 14, and a limit slip ring is provided at the connection between the main linkage screw 14 and the telescopic pressure rod 15. An adjusting sleeve 16 is sleeved on the lower outer end of the telescopic pressure rod 15 for limiting... Both the slip ring and the adjusting sleeve 16 are limited by the limiting groove and the height adjusting slide rod 3. The lower end of the telescopic pressure rod 15 is provided with a height locking spring 17. The telescopic pressure rod 15 is elastically connected to the upper end of the adjusting sleeve 16 through the height locking spring 17. The height fixing component includes a locking plate 18 and a height locking head 19. The lower end of the adjusting sleeve 16 is connected to the locking plate 18, and the lower end of the locking plate 18 is tapered. Both ends of the locking plate 18 are provided with height locking heads 19, and both height locking heads 19 are slidably connected to the inside of the height locking slide 11 and fit against the inside of the height adjusting sleeve 2. During the process of locking the welding height of the workpiece, the locking handle 12 is rotated. The locking handle 12 drives the main linkage shaft 13 to rotate inside the height adjustment slide rod 3. The main linkage shaft 13 drives the height fixing component and the orientation component to move. Since the main linkage screw 14 can be limited with the height adjustment slide rod 3 through the limit slip ring and the limit slide groove, the main linkage screw 14 can only slide up and down inside the height adjustment slide rod 3 and cannot rotate. This allows the main linkage shaft 13 to drive the main linkage screw 14 and the telescopic pressure rod 15 to move downward through the thread, allowing the telescopic pressure rod 15 to be locked by the height locking spring. Spring 17 pushes the adjusting sleeve 16 and locking plate 18 until the locking plate 18 fits against the lower inner wall of the height-locking slide block 11. This allows the two height-locking clips 19 to slide outward under the push of the tapered outer wall of the lower end of the locking plate 18 and fit tightly against the inner wall of the adjusting sleeve 2, thereby locking the position of the adjusting sleeve 2 and the height-locking slide block 11, and thus fixing the position of the adjusting sleeve 2 and the height-locking slide rod 3. During this process, the main linkage shaft 13 will simultaneously drive the orientation component to move upward a distance, but not enough to lock the welding direction of the workpiece.
[0031] like Figure 5As shown, the orientation component includes a sequencer slide 20 and a locking head 21. The sequencer slide 20 is slidably connected to the upper end of the height adjustment slide rod 3, and is limited by a limiting slide bar and a limiting slide groove. The sequencer slide 20 is threaded to the outside of the main linkage shaft 13. The locking head 21 is slidably connected to the upper end of the sequencer slide 20. The lower end of the locking head 21 is connected to a support base 22, which is slidably connected inside the sequencer slide 20 and is connected to the sequencer slide 20 by a limiting slide bar and a limiting slide groove. 0 is used for limiting the position. A support spring 23 is installed inside the lower end of the support base 22, and is elastically connected to the inside of the adjusting slide 20 via the support spring 23. During the process of locking the welding direction of the workpiece, after the welding height of the workpiece is fixed, because the lower end of the locking plate 18 is attached to the inner wall of the lower end of the height-locking slide 11, the adjusting sleeve 16 and the locking plate 18 will remain stationary. At this time, if the locking handle 12 is continued to be rotated, the telescopic pressure rod 15 will slide downwards inside the adjusting sleeve 16, and... The locking spring 17 maintains the pushing force on the locking plate 18, ensuring that the welding height of the workpiece remains unchanged. The main linkage shaft 13 continues to rotate under the drive of the locking handle 12. Since the sequence adjustment slide 20 is limited by the limit slide bar and the limit slide groove to the height adjustment slide rod 3, and the support base 22 is limited by the limit slide bar and the limit slide groove to the sequence adjustment slide 20, the sequence adjustment slide 20 can only slide up and down inside the height adjustment slide rod 3 and cannot rotate. The locking head 21 and the locking head 22 are also limited by the limit slide bar and the limit slide groove. It can only slide up and down inside the support base 22 and cannot rotate. The height adjustment slide 3 can drive the sequence adjustment slide 20 to move upward inside the upper end of the height adjustment slide 3 through the thread. The sequence adjustment slide 20 supports the support base 22 and the locking head 21 to move upward through the support spring 23 until the upper end of the locking head 21 engages with the locking tooth groove opened on the inner wall of the upper end of the direction adjustment head 4, thereby locking the position of the height adjustment slide 3 and the direction adjustment head 4, and thus fixing the welding direction of the workpiece.
[0032] like Figure 7 and Figure 8As shown, a side linkage rod 24 is rotatably connected to the left end of the connecting side rod 5, and the left end of the side linkage rod 24 is provided with a helical tooth groove, which passes through the right end of the directional head 4. A linkage helical gear 33 is connected to the upper side of the main linkage shaft 13, and the linkage helical gear 33 is rotatably connected to the inside of the directional head 4. The linkage helical gear 33 meshes with the upper side of the left end of the helical tooth groove of the side linkage rod 24. A side linkage threaded rod 25 is threadedly connected to the right end of the side linkage rod 24, and the side linkage threaded rod 25 is limited to the connecting side rod 5 by a limiting slider and a limiting groove. A telescopic connecting rod 26 is connected to the right end of the side linkage threaded rod 25, and a linkage push rod 27 is sleeved on the outside of the right end of the telescopic connecting rod 26. The shaft tilt angle is fixed. The fixed component includes an angle lock head 28, which is slidably connected inside the right end of the angle turn head 6 and engaged outside the left end of the angle turn head 7. A linkage push rod 27 is inserted inside the left end of the angle lock head 28, and an angle locking spring 29 is provided inside the right end of the linkage push rod 27 and elastically connected inside the angle lock head 28 through the angle locking spring 29. During the process of locking the welding shaft angle of the workpiece, if the locking handle 12 is rotated, the telescopic pressure rod 15 will continue to slide downward inside the sequence sleeve 16, and the sequence slide 20 will slide upward outside the locking chuck 21 and the support base 22, and be held in place by the support spring 23. The pushing force of the support base 22 and the side linkage threaded rod 25 ensures that the welding direction of the workpiece remains unchanged. At the same time, during the locking process of the workpiece welding height and welding direction, the side linkage threaded rod 25 is driven by the side linkage rod 24 and engages with the linkage push rod 27. The locking handle 12 drives the linkage helical gear 33 to rotate through the main linkage shaft 13, and drives the side linkage rod 24 to rotate through the meshing of the linkage helical gear 33 with the left end helical tooth groove of the side linkage rod 24. Since the side linkage threaded rod 25 is limited by the limiting slider and the limiting groove with the connecting side rod 5, the side linkage threaded rod 25 can only slide left and right inside the connecting side rod 5 and will not rotate, so that the side linkage rod 24 can drive the side linkage through the thread. The threaded rod 25 engages with the linkage push rod 27 and pushes the linkage push rod 27. Under the push of the side linkage threaded rod 25, the linkage push rod 27 slides to the right and pushes the tilt lock head 28 through the tilt lock spring 29. This allows the tilt lock head 28 to slide out from inside the corner head 6 under the push of the tilt lock spring 29 and engage with the locking tooth groove on the semi-cylindrical outer wall of the left end of the tilt head 7, thereby locking the position of the corner head 6 and the tilt head 7, and fixing the tilt angle of the welding shaft of the workpiece. During this process, the main linkage shaft 13 will simultaneously drive the shaft angle fixing assembly to move to the right by a distance, but not enough to lock the tilt angle of the welding shaft of the workpiece.
[0033] like Figure 6 and Figure 7As shown, the shaft angle fixing assembly includes an angle lock anti-slip seat 31 and an angle lock head 32. A push ring 30 is connected to the outer side of the left end of the linkage push rod 27. The angle lock anti-slip seat 31 is sleeved on the outside of the linkage push rod 27, and the angle lock anti-slip seat 31 is slidably connected to the inside of the right end of the connecting side rod 5 and located at the right end of the push ring 30. Multiple angle lock heads 32 are connected to the outer side of the right end of the angle lock anti-slip seat 31, and the right ends of the multiple angle lock heads 32 pass through the outside of the right end of the connecting side rod 5 and are locked inside the angle lock head 6. An unlocking spring 34 is provided on the inner side of the right end of the angle lock anti-slip seat 31, and is elastically connected to the inside of the connecting side rod 5 through the unlocking spring 34. During the process of locking the welding shaft angle of the workpiece, the locking handle 12 continues to rotate. The telescopic pressure rod 15 continues to slide downward inside the adjusting sleeve 16, and the adjusting slide block 20 continues to slide upward outside the locking head 21 and the support base 22. At the same time, the linkage push rod 27 slides to the right inside the left end of the tilt lock head 28 and maintains the pushing force on the tilt lock head 28 through the tilt lock spring 29 to ensure that the tilt angle of the workpiece welding shaft remains unchanged. The linkage push rod 27 can push the corner locking slide block 31 and the corner lock head 32 through the pushing ring 30. When the corner lock head 32 extends from the right end of the connecting side rod 5, the corner lock head 32 will be locked into the locking tooth groove opened at the left end of the corner head 6, thereby locking the position of the connecting side rod 5 and the corner head 6, and thus fixing the welding shaft angle of the workpiece.
[0034] In addition, while fixing the shaft rotation angle of the workpiece, the limiting slip ring at the connection between the main linkage screw 14 and the telescopic pressure rod 15 is just in contact with the upper end of the sequence sleeve 16, the support base 22 just slides to the lowermost side of the sequence slide 20, and the linkage push rod 27 just slides to the rightmost side of the tilt lock head 28. At this time, the main linkage shaft 13 can no longer rotate, so that the height fixing component, orientation component, shaft rotation angle fixing component and shaft tilt angle fixing component completely fix the welding height, direction, shaft rotation angle and shaft tilt angle of the workpiece, ensuring the stability of the welding position.
[0035] Conversely, when the locking handle 12 is rotated in the opposite direction, the linkage assembly can drive the height fixing assembly, orientation assembly, shaft angle fixing assembly, and shaft tilt angle fixing assembly to unlock in reverse order. Specifically, when the push ring 30 slides to the left, the angle locking slide 31 and angle lock head 32 will be disengaged from the locking groove at the left end of the angle head 6 under the action of the unlocking spring 34, releasing the lock between the connecting side rod 5 and the angle head 6. Then, the linkage push rod 27 first slides to the leftmost side of the tilt lock head 28, causing the tilt lock head 28 to separate from the tilt head 7, releasing the lock between the angle head 6 and the tilt head 7. Next, the sequence sliding... The seat 20 will slide to the lowest side of the support base 22 before the telescopic pressure rod 15 and after the linkage push rod 27. It will then drive the locking head 21 to slide downward through the support base 22 and disengage from the locking tooth groove at the lower end of the adjusting head 4, thus releasing the lock between the height adjusting slide rod 3 and the adjusting head 4. Finally, the telescopic pressure rod 15 will slide to the uppermost side of the adjusting sleeve 16 and slide upward between the two height locking heads 19 through the adjusting sleeve 16 and the locking plate 18, thus releasing the push on the two height locking heads 19 and preventing them from being tightly fitted to the inner wall of the height adjusting sleeve 2, thereby releasing the lock between the height adjusting sleeve 2 and the height adjusting slide rod 3.
[0036] Therefore, the linkage component can lock and unlock the height-fixing component, orientation component, shaft rotation angle fixing component, and shaft tilt angle fixing component in an orderly and reverse order with the linkage component. The above operations can be quickly completed by simply turning the locking handle 12 in both directions. The operation method is simple and fast.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
