Description

Technical Field

[0001] The utility model relates to the technical field of welding fixtures, in particular to a welding fixture. Background Art

[0002] A fixture is a device used to fix the workpiece during the mechanical manufacturing process so that it occupies the correct position for construction or inspection. During the welding process, in order to prevent the workpiece from shifting, a fixture is needed to fix the position of the workpiece.

[0003] At present, there are many types of fixing fixtures used in welding. When right-angle welding is required, a right-angle fixture is used to fix the workpiece. In the process of fixing the workpiece, the staff first places the two workpieces to be welded on the fixture, and then rotates the threaded rod to make the triangle plate and the workpiece abut against each other, so that the two workpieces remain vertical. Since the triangle plate only provides lateral clamping force on the workpiece, it is difficult to limit the vertical direction of the workpiece. Therefore, in the actual welding process, some workpieces are prone to warping. For this reason, we propose a welding fixture to solve the above problem. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Referring to Figures 1-4 , a welding fixture includes a bottom plate 1. A first screw rod 2 is inserted into the interior of the bottom plate 1, and the front end of the first screw rod 2 is connected to a triangular plate 3. The connection manners of the first screw rod 2 with the bottom plate 1 and the triangular plate 3 are prior arts and will not be elaborated here. Fixing plates 5 are distributed on the side of the triangular plate 3, and the bottom end of the fixing plate 5 is fixedly connected to the bottom plate 1. A connecting plate 6 is provided at the top of the fixing plate 5, and threaded grooves are formed in the interior of the connecting plate 6. The connecting plate 6 is arranged in an L-shaped structure, and the interior of the connecting plate 6 is connected to the fixing plate 5 by bolts. A second screw rod 7 is inserted into the threaded groove, and the top end of the second screw rod 7 is connected to a connecting rod 8 through a bearing. A positioning plate 9 is provided at the bottom end of the connecting rod 8. The positioning plate 9 is arranged in a strip shape, and a clamping force in the vertical direction can be applied to the workpiece through the positioning plate 9 to effectively prevent the workpiece from warping during the welding process.

[0023] Furthermore, referring to Figure 1 , it can be known that first rubber pads 4 are glued to both ends of the triangular plate 3, and anti-slip particles are evenly distributed on the outer surface of the first rubber pads 4. Through the mutual cooperation of the first rubber pads 4 and the anti-slip particles, the friction between the triangular plate 3 and the workpiece can be effectively improved, and thus the clamping effect of the triangular plate 3 on the workpiece can be ensured.

[0024] Furthermore, referring to Figure 3 and Figure 4 , it can be known that a second rubber pad 11 is glued to the lower side of the positioning plate 9, and anti-slip lines are formed below the second rubber pad 11. During use, through the second rubber pad 11 made of rubber material and the formation of the anti-slip lines, the clamping effect of the positioning plate 9 on the workpiece can be improved.

[0025] Furthermore, referring to Figure 2 and Figure 3 , it can be known that two groups of connecting rods 8 are provided above the positioning plate 9. One group of connecting rods 8 is connected to the second screw rod 7 through a bearing, and the top end of the other group of connecting rods 8 is connected to a guiding rod 15. A moving groove adapted to the guiding rod 15 is formed in the interior of the connecting plate 6. Through the mutual cooperation of the moving groove and the guiding rod 15, the guiding of the connecting rod 8 can be realized to ensure the stable up and down movement of the positioning plate 9.

[0026] Furthermore, referring to Figure 4It can be known that connecting sleeves 12 are respectively connected to the positions on the upper side of the positioning plate 9 corresponding to the connecting rod 8, and limiting rods 13 are inserted into the sides of the connecting sleeves 12. One end of the limiting rod 13 is connected to a limiting disc 14, and the other end of the limiting rod 13 extends into the connecting rod 8. A clamping groove adapted to the limiting rod 13 is provided at the bottom end of the connecting rod 8. Through the mutual cooperation of the connecting sleeve 12 and the limiting rod 13, it is convenient for the staff to timely disassemble the positioning plate 9 that has reached the service life.

[0027] Further, referring to Figure 4 It can be known that external threads are provided on the outer surface of the limiting rod 13, and internal threads are provided on the inner wall of the clamping groove. Through the threaded cooperation of the limiting rod 13 and the clamping groove, the tightness of the limiting rod 13 inserted into the internal clamping groove of the connecting rod 8 can be ensured, so as to ensure the reliability during the installation process of the positioning plate 9.

[0028] Further, referring to Figure 3 It can be known that a connecting ring is sleeved on the second screw rod 7, and a plurality of rotating pieces 10 are evenly distributed on the periphery of the connecting ring. Through the connection of the connecting ring and the plurality of rotating pieces 10, it is convenient for the staff to rotate the second screw rod 7, thereby effectively improving the convenience during the use of the device.

[0029] Working principle: When the utility model is in use, the staff can first place the tool that needs to weld a right angle on the bottom plate 1 and make it fit against the outer walls of the two fixing plates 5. Then the staff can rotate the first screw rod 2, so that the triangular plate 3 abuts against the workpiece to realize the lateral position limitation of the workpiece. Subsequently, the staff can rotate the two rotating pieces 10 in sequence to drive the rotation of the second screw rod 7, so that the connecting rod 8 connected above the second screw rod 7 moves under force. During the movement of the connecting rod 8, the guiding rod 15 connected to its side can be driven to slide inside the connecting plate 6 to realize the guiding of the positioning plate 9. When the second rubber pad 11 glued to the lower side of the positioning plate 9 abuts against the upper side of the workpiece to provide a vertical pressing force to the workpiece, the clamping effect on the workpiece can be improved. Then the staff can use the tool to weld the right angle of the workpiece. The above is the entire working principle of the utility model.
