Technical Field

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

[0002] A car is composed of an engine system, a running system, body accessories, a steering system and a braking system.

[0003] During the assembly process of automobile parts, the automobile parts need to be welded, and in the welding process of automobile parts, tooling and fixtures are needed to weld the automobile parts before the automobile is assembled and produced.

[0004] In the welding clamping process of automobile parts, refer to the patent document CN220498216U. The device proposed in the patent document drives the threaded rod to rotate by the first motor so that the automobile parts can move left and right. The second motor can be set to allow the automobile parts to rotate in the horizontal direction. The height of the two ends of the clamped automobile parts can be adjusted by the setting of the first cylinder. The automobile parts can be turned over by the setting of the third motor. The position and angle of the automobile parts in all directions can be adjusted. Through such a design, the position and angle of the automobile parts can be adjusted to cooperate with the welding head for welding, so there will be no welding dead angle. The whole process does not require manual operation and is very practical. However, in the actual application of clamping automobile parts, although the device can adjust the accessories in all directions, it requires the staff to frequently start multiple driving devices in sequence to adjust the automobile parts, and the residue dropped during the welding process of the automobile parts will fall to the surface of the threaded rod, which is easy to affect the transmission effect, and the support plate of the device has fewer force points and is prone to the risk of tilting; To this end, we provide a tooling fixture for welding automobile parts to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a tooling fixture for welding automobile parts.

DETAILED DESCRIPTION

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] As described in the background technology, although the device can adjust the accessories in all directions, it requires the staff to frequently start multiple driving devices in sequence to adjust the automobile accessories, and the residues dropped during the welding process of the automobile accessories will fall to the surface of the threaded rod, which is easy to affect the transmission effect. In addition, the support plate of the device has fewer force points and is prone to the risk of tilting. For this reason, this embodiment provides a tooling fixture for welding automobile accessories. The device can adjust the lateral and vertical adjustments during the clamping process of automobile accessories, and can be reversed to weld the reverse side after welding, and the transmission effect is stable and has a large load-bearing capacity, thereby avoiding the risk of damage to components due to excessive pressure during transmission.

[0025] See also Figure 1 - Figure 4 This embodiment proposes a tooling fixture for welding automotive parts, including a main board 1, a clamping and adjusting mechanism 2 is provided at the bottom of the main board 1, the clamping and adjusting mechanism 2 includes a first servo motor 201 fixedly connected to the bottom surface of a connecting plate on the outer surface of the main board 1, the output shaft of the first servo motor 201 is fixedly connected to a threaded rod 202, the outer surface of the threaded rod 202 is threadedly connected to a screw ring 203, and the two connecting plates on the outer surface of the screw ring 203 are both hinged with a transmission frame 204.

[0026] refer to Figure 2 and Figure 3The setting of the first servo motor 201 can drive the threaded rod 202 to rotate, so that the threaded rod 202 drives the screw ring 203 to move, and the screw ring 203 will drive the transmission frame 204 to move synchronously during the movement, thereby driving the subsequent components to clamp the automotive accessories through the transmission frame 204.

[0027] The threaded rod 202 has a self-locking property, thereby avoiding the risk of reverse movement of the threaded rod 202 when moving with the screw ring 203, and can also disperse the clamping force through the transmission frame 204, thereby avoiding the threaded rod 202 being damaged due to a large load.

[0028] A first limit plate 3 is fixedly connected to the bottom surface of the main board 1, and the outer surface of the first limit plate 3 is rotatably connected to the end of the threaded rod 202 away from the first servo motor 201, and the ends of the two sliding rods 206 close to each other are fixedly connected to the second limit plate 4, and a first slide rail 5 is fixedly connected to the bottom surface of the main board 1, and the outer surface of the first slide rail 5 is slidably connected to the protruding slider on the outer surface of the screw ring 203.

[0029] By setting the first limit plate 3, the second limit plate 4 and the first slide rail 5, the screw ring 203 and the slide ring 207 can be limited and blocked, and the setting of the first slide rail 5 can enable the screw ring 203 to slide stably, preventing the screw ring 203 from rotating and shaking during movement and affecting the transmission effect, thereby greatly improving the stability of the device.

[0030] The two adjustment frames 11 are fixedly connected to the side faces away from each other with the second servo motor 12, and the output shafts of the second servo motors 12 pass through the outer surface of the adjustment frames 11 and are fixedly connected to the clamping frames 13. By setting the adjustment frames 11, the automobile parts can be better reversed after the front welding is completed, thereby eliminating the trouble of taking out the automobile parts and then performing the reverse clamping operation.

[0031] The upper surfaces of the two clamping frames 13 are threadedly connected with bolts 14, and the lower ends of the bolts 14 are fixedly connected with clamping pads 15. By setting the clamping frames 13 and the bolts 14, the automobile accessories can be further clamped and fixed better, thereby avoiding shaking during the welding process of the automobile accessories.

[0032] Support legs 16 are fixedly connected to the four corners of the bottom surface of the mainboard 1, and the lower ends of the support legs 16 are fixedly connected to foot pads 17. By providing the support legs 16, the entire device can be better supported and carried, thereby compensating for the slight shaking generated during the welding process of automotive parts, thereby greatly improving the stability of the device.

[0033] Two fixed plates 205 are fixedly connected to the bottom surface of the main board 1, and the sides of the fixed plates 205 that are close to each other are fixedly connected to sliding rods 206, the outer surfaces of the two sliding rods 206 are slidably connected to slip rings 207, and the slip rings 207 are hinged to the transmission frame 204, and two sliding grooves 208 are provided on the bottom surface of the main board 1, and the ends of the two transmission frames 204 that are away from each other are fixedly connected to connecting rods 209, and the connecting rods 209 are slidably connected to the sliding grooves 208, and the upper ends of the two connecting rods 209 are fixedly connected to the transmission frame 2010.

[0034] refer to Figures 1 to 3 The setting of the slide rod 206 can facilitate the transmission frame 204 to pull the slip ring 207 to slide in a limited position during the movement, so that the slip ring 207 drives the connecting rod 209 to slide in the slide groove 208 in a limited position, and then the transmission frame 2010 can also replace and install different clamping devices according to needs to clamp the automobile accessories, thereby greatly improving the practicality of the overall device.

[0035] The two slip rings 207 are fixedly connected with a connecting ring 6 on one side close to the fixed plate 205, and the outer surfaces of the two sliding rods 206 are sleeved with telescopic springs 7, and the telescopic springs 7 are fixedly connected to the fixed plate 205. By setting the telescopic springs 7, the slip rings 207 can be better buffered, thereby avoiding the risk of collision and damage between the slip rings 207 and the fixed plate 205 during movement.

[0036] Two symmetrical second slide rails 8 are fixedly connected to the upper surface of the main board 1, and the left and right ends of the two second slide rails 8 are fixedly connected with a stop bar 9, and the stop bar 9 is located outside the transmission frame 2010. By setting the second slide rails 8, the transmission frame 2010 can be better limited in movement, thereby preventing the transmission frame 2010 from compensating for the shaking generated by the subsequent clamping components during the clamping process of the automotive accessories, thereby preventing the transmission frame 2010 from deflecting and shaking during the adjustment of the clamping movement.

[0037] The upper surfaces of the two transmission frames 2010 are fixedly connected with the first adjustment cylinder 10, and the inner wall of the first adjustment cylinder 10 is slidably connected with the adjustment frame 11. By setting the first adjustment cylinder 10, the clamping height of the automobile accessories can be better adjusted during clamping, thereby avoiding the situation where the welding operation of the automobile accessories is large.

[0038] Working principle: The whole device is moved to a predetermined position by the support leg 16. When the auto parts are clamped, the first servo motor 201 is started, and the output shaft of the first servo motor 201 drives the threaded rod 202 to rotate, and the threaded rod 202 drives the screw ring 203 to move, and the screw ring 203 drives the slip ring 207 to slide on the surface of the slide rod 206 through the transmission frame 204, so that the transmission frame 204 drives the transmission frame 2010 to adjust the movement through the connecting rod 209. After the adjustment is completed, the auto parts are placed in the clamp. At the tightening frame 13, by rotating the bolt 14, the bolt 14 drives the clamping pad 15 to clamp the auto part. If the auto part is large, the clamping height can be adjusted by the first adjusting cylinder 10 and the adjusting frame 11. After all adjustments are completed, the front side of the auto part can be welded. After the front side welding is completed, the second servo motor 12 is started, and the output shaft of the second servo motor 12 drives the clamping frame 13 and the auto part to reverse, so that the staff can weld the back side of the auto part, thereby greatly improving the practicality of the overall device.
