Technical Field

[0001] This utility model relates to the field of welding fixtures, specifically a welding fixture rotary table. Background Technology

[0002] In modern industrial production, welding is a common method for joining metal parts, and its efficiency directly affects the overall efficiency of the production line. Therefore, it is necessary to design a welding fixture that can quickly and accurately adjust the position and angle of the workpiece to improve welding efficiency.

[0003] The differences in the shape and size of different workpieces require welding fixtures to be highly flexible. Welding fixtures need to be able to adapt to the needs of different workpieces and realize welding operations at multiple angles and positions. Current fixed welding fixtures can only realize welding operations at a single position and cannot adapt to the needs of different workpieces. Utility Model Content

[0006] A welding fixture rotary table includes two parallel tracks. Fixed plates are fixedly connected between the left and right ends of each track. A double-acting lead screw is rotatably connected between the middle of the two fixed plates. A motor is fixedly mounted on the outer right wall of the right fixed plate. The left end of the motor's output shaft is fixedly connected to the right end of the double-acting lead screw. Two movable seats are symmetrically distributed on the top of each track. The movable seats are threaded into the double-acting lead screw. A bracket is fixedly connected to the top of each movable seat. A turntable is mounted on the top of each turntable. A clamping mechanism is mounted on the top of each turntable. A support shaft is fixedly connected to the bottom of each turntable, and the support shaft penetrates downwards through the support.

[0019] like Figure 1-6 As shown: A welding fixture rotary table includes two tracks 1, which are parallel to each other. Fixed plates 2 are fixedly connected between the left and right ends of each track 1. A bidirectional lead screw 3 is rotatably connected between the middle of the two fixed plates 2. A motor 4 is fixedly installed on the outer right wall of the right fixed plate 2. The left end of the output shaft of the motor 4 is fixedly connected to the right end of the bidirectional lead screw 3. Two movable seats 5 are symmetrically distributed on the top of each track 1. The movable seats 5 are threadedly engaged with the bidirectional lead screw 3. A bracket 7 is fixedly connected to the top of each movable seat 5. A turntable 8 is located on the top of the bracket 7. A clamping mechanism is installed on the top of each turntable 8. A support shaft 15 is fixedly connected to the bottom of each turntable 8, extending downwards through the top of the bracket 7. The bottom end of 5 is rotatably connected to the top of the movable seat 5. The outer wall of the support shaft 15 is rotatably connected to the bracket 7. A bevel gear 16 is fixedly connected to the bottom outer wall of the support shaft 15. A mounting plate 17 is fixedly connected to the front side wall of the bracket 7. A support plate 18 is vertically fixedly connected to the top front side of the movable seat 5. A rotating shaft 19 is rotatably connected to the top of the support plate 18. The front end of the rotating shaft 19 passes through the mounting plate 17. The front end of the rotating shaft 19 is rotatably connected to the mounting plate 17. A bevel gear 20 is fixedly connected to the rear end of the rotating shaft 19. The bevel gear 20 meshes with the bevel gear 16. An angle adjustment handle 21 is fixedly connected to the front end of the rotating shaft 19. A locking nut 22 is threadedly connected to the front outer wall of the rotating shaft 19. The rear side wall of the locking nut 22 abuts against the front outer wall of the mounting plate 17.

[0020] The clamping mechanism includes a slotted plate 9, which is fixedly connected to the top of the turntable 8. A clamping screw 10 is rotatably connected between the front and rear inner walls of the slotted plate 9. The threads of the clamping screw 10 are distributed in a mirror-symmetrical manner. Two centering clamps 11 are threadedly connected to the outer wall of the clamping screw 10. The two centering clamps 11 are symmetrically distributed front and rear. A clamping plate 12 is fixedly connected to the top of the centering clamp 11. The front end of the clamping screw 10 passes through the front side of the slotted plate 9. A throttle 13 is fixedly connected to the front end of the clamping screw 10. A locking nut 14 is threadedly connected to the outer wall of the front end of the clamping screw 10. The rear side of the locking nut 14 abuts against the outer wall of the front end of the slotted plate 9.

[0021] The movable seat 5 is connected to the double-acting screw 3 via a threaded connection, and can move left and right on the track 1. When the motor 4 is started, the output shaft of the motor 4 drives the double-acting screw 3 to rotate. Due to the threaded connection of the double-acting screw 3, the two movable seats 5 will move towards each other or away from each other at the same time, thereby adjusting the relative position of the two clamping mechanisms.

[0022] Place the pipe or plate to be welded on the clamping mechanism, turn the handle 13, and the handle 13 will drive the clamping screw 10 to rotate. Since the thread direction of the clamping screw 10 is mirror symmetrically distributed, the two centering clamps 11 will move towards the middle at the same time to clamp the pipe or plate. The clamping plate 12 can be used to further fix the plate.

[0023] The angle adjustment handle 21 is cranked, which drives the rotating shaft 19 to rotate. The bevel gear 20 at the rear end of the rotating shaft 19 meshes with the bevel gear 16 at the bottom of the support shaft 15, thereby driving the support shaft 15 and the turntable 8 to rotate. When the turntable 8 rotates, the clamping mechanism on it and the clamped workpiece will also rotate to the required angle.

[0024] After adjusting to the required angle, tighten the locking nut 22 so that it abuts against the front outer wall of the mounting plate 17, thereby fixing the position of the rotating shaft 19 and the turntable 8.

[0025] It allows users to weld two clamped objects at different joint angles.
