[0002] With a long history of automotive development, the UK has brought together world-leading companies, universities, racing industries, and independent projects, and has the capability to transform and develop new technologies. Its expertise and forward-thinking approach are unique advantages for developing core automotive technologies. In the production of automotive parts, the parts need to be clamped to ensure their stability and prevent them from shaking during processing, which could affect their precision.

[0003] A prior art tooling fixture for automotive parts production, disclosed in CN218426931U, includes a fixed plate with a plurality of through holes on its upper surface. Support legs are fixedly connected to the four corners of the lower surface of the fixed plate. A retraction mechanism is located below the fixed plate, and a clamping mechanism is located above it. The clamping mechanism includes a support plate, the bottom of which is fixedly connected to the middle of the left and right sides of the upper surface of the fixed plate.

A handle is fixedly connected to one end of the threaded shaft, a return spring is located on the outer surface of the other side of the threaded shaft, and a clamping plate is fixedly connected to the other end of the threaded shaft.

[0004] The device can provide a stable grip for automotive parts, but because the gripping mechanism is fixed in position and cannot rotate, manual adjustments are required when processing other parts of the automotive parts, which is quite troublesome. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a fixture for the production of automotive parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fixture for producing automotive parts, comprising a base plate, a mounting plate rotatably connected to the base plate, support plates fixedly connected to both sides of the mounting plate, a one-way threaded rod rotatably mounted through and on both support plates, the two one-way threaded rods being arranged opposite to each other, a clamping sleeve being threadedly connected to the outer side of the one-way threaded rod, a jaw being rotatably connected to the opposite ends of the two clamping sleeves, a two-way threaded rod rotatably connected between the two support plates and located below the one-way threaded rod, two placement platforms threaded through the two-way threaded rod, a sliding groove being provided on the mounting plate, and the placement platform being slidably connected to the sliding groove.

[0007] Preferably, a horizontally arranged telescopic rod is fixedly connected to the support plate, and the telescopic end of the telescopic rod is fixedly connected to a clamping sleeve near the telescopic rod.

[0008] Preferably, a toothed ring is fixedly connected to the outer side of the gripper, and a gear that meshes with the toothed ring is rotatably mounted on the clamping sleeve.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figure 1-4 As shown, a fixture for producing automotive parts includes a base plate 1, a mounting plate 3 rotatably connected to the base plate 1, support plates 6 fixedly connected to both sides of the mounting plate 3, a one-way threaded rod 9 rotatably mounted through both support plates 6, the two one-way threaded rods 9 being arranged opposite each other, a clamping sleeve 11 threadedly connected to the outside of the one-way threaded rod 9, a jaw 12 rotatably connected to the opposite ends of the two clamping sleeves 11, a two-way threaded rod 5 located below the one-way threaded rod 9 rotatably connected between the two support plates 6, two placement platforms 7 threadedly passing through the two-way threaded rod 5, a sliding groove 4 opened on the mounting plate 3, the placement platforms 7 being slidably connected to the sliding groove 4, a toothed ring 14 fixedly connected to the outside of the jaw 12, and a gear 13 rotatably mounted on the clamping sleeve 11 that meshes with the toothed ring 14.

[0023] In this technical solution, by setting a toothed ring 14 and a gear 13, after the two grippers 12 stably clamp the automotive parts, the gear 13 rotates to drive the toothed ring 14 to rotate, which in turn drives the two grippers 12 to rotate, thereby causing the automotive parts to flip and process different positions of the automotive parts. By setting a bidirectional threaded rod 5, when the bidirectional threaded rod 5 rotates, it drives the two placement tables 7 to move towards or away from each other along the axial direction of the bidirectional threaded rod 5. When the automotive parts are flipped, in order to prevent them from colliding with the placement tables 7, the two placement tables 7 are moved in a direction away from each other, so that the placement tables 7 are separated from the grippers 12.

[0024] like Figure 2 As shown, a horizontally arranged telescopic rod 10 is fixedly connected to the support plate 6, and the telescopic end of the telescopic rod 10 is fixedly connected to the clamping sleeve 11 near the telescopic rod 10.

[0025] In this technical solution, by setting a telescopic rod 10, under the limit of the telescopic rod 10, when the one-way threaded rod 9 rotates, the clamping sleeve 11 moves along the axial direction of the one-way threaded rod 9, causing the two jaws 12 to move closer to each other or open, thereby clamping or releasing the automotive parts.

[0026] like Figure 1 As shown, an external gear ring 2 is fixedly connected to the outer side of the mounting plate 3, and a gear 13 that meshes with the external gear ring 2 is rotatably mounted on one side of the base plate 1.

[0027] In this technical solution, when the drive gear 13 rotates, it drives the external gear ring 2 to rotate. The external gear ring 2 will drive the mounting plate 3 to rotate around the rotation connection point with the base plate 1, which improves the flexibility of the fixture in the process of processing automotive parts, and allows the automotive parts fixed on the mounting plate 3 to be presented to the processing equipment in different positions.

[0028] like Figure 1 and Figure 3 As shown, motors 8 are fixedly connected to one side of the two support plates 6, one side of the base plate 1, and one end of the clamping sleeve 11. The motor 8 on the support plate 6 is used to drive the unidirectional threaded rod 9 to rotate. The motor 8 on the base plate 1 is used to drive the gear 13, which is close to the position of the motor 8, to rotate. The motor 8 on the clamping sleeve 11 is used to drive the gear 13, which is close to the position of the motor 8, to rotate. One side of one support plate 6 is also fixedly connected to a motor 8 for driving the bidirectional threaded rod 5 to rotate.

[0029] Working principle: The car parts are placed on two placement tables 7. The motor 8 located on the support plate 6 is started. The motor 8 drives the one-way threaded rod 9 to rotate, which drives the clamping sleeve 11 to move, and then drives the two jaws 12 to move closer to each other until the car parts are stably clamped. When processing different sides of the car parts, the motor 8 drives the two-way threaded rod 5 to rotate, which drives the two placement tables 7 to move in opposite directions along the axial direction of the two-way threaded rod 5, so that the placement tables 7 and the jaws 12 are separated. Then the motor 8 drives the gear 13 to rotate, which drives the gear ring 14 to rotate, and then drives the two jaws 12 to rotate, thereby causing the car parts to flip.

[0030] The wiring diagram of the motor 8 in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor 8 will not be explained in detail.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
