[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] like Figure 1-4 As shown, a fixture for an automobile parts production line includes a workbench 1, both sides of the workbench 1 are embedded with sliding blocks 3 for sliding connection, both sides of the workbench 1 are embedded with moving screws 2 that are rotatably connected to the sliding blocks 3, the opposite ends of the two moving screws 2 extend to the outside of the workbench 1, an electric push rod 16 is fixedly connected to the middle position of the bottom of the workbench 1, the telescopic end of the electric push rod 16 passes through the workbench 1 and is fixedly connected to a soft pad 4 that is embedded and plugged into the workbench 1, the lamp housing is placed on the workbench 1, when in use, the position of the sliding block 3 is adjusted by rotating the moving screw 2 according to the lateral length of the lamp housing, that is, the distance between the two sliding blocks 3 is adjusted to a suitable length, and when in actual use, the electric push rod 16 is telescopically extended to realize the lifting and lowering of the soft pad 4, and the soft pad 4 is used to press against the surface of the lamp housing to realize the support of the middle position of the lamp housing:

[0025] A screw rod 11 is fixedly connected to the upper surface of the sliding block 3, and a first swing arm 5 and a second swing arm 9 are sleeved on the screw rod 11. The first swing arm 5 and the second swing arm 9 are arranged in a rectangular shape, and the inner walls of the first swing arm 5 and the second swing arm 9 are slidably connected to the surface of the screw rod 11. The first swing arm 5 and the second swing arm 9 are rotatably connected to the ends away from the screw rod 11. As shown in the figure, the first swing arm 5 and the second swing arm 9 are staggered up and down, so it is convenient for personnel to adjust the position of the positioning blocks 6 installed on the end faces of the first swing arm 5 and the second swing arm 9 by adjusting the inclination angle of the first swing arm 5 and the second swing arm 9 and sliding relative to the screw rod 11 with the assistance of the screw rod 11, that is, to ensure that the two positioning blocks 6 on one side can fit the edges of lamp shells with different edge shapes. The lead screw 11 is threaded with a clamping nut 17, and there is damping cooperation between the clamping nut 17 and the second swing arm 9, between the second swing arm 9 and the first swing arm 5, and between the first swing arm 5 and the sliding block 3. The damping cooperation is achieved by sticking rubber pads on the surfaces of the first swing arm 5 and the second swing arm 9. After the angles and positions of the first swing arm 5 and the second swing arm 9 are adjusted, the clamping nut 17 is rotated to make the clamping nut 17 descend to generate downward pressure on the second swing arm 9, thereby achieving pressure from the second swing arm 9 to the first swing arm 5, so that the first swing arm 5 is tightly attached to the surface of the workbench 1, and the friction force is increased by increasing the pressure, thereby achieving the fixation of the position of the second swing arm 9, that is, ensuring that the positioning blocks 6 are stably distributed around the lamp housing.

[0026] In order to adapt to lamp shells of different heights and curvatures: the outer walls on both sides of the second swing arm 9 are fixedly connected with a horizontally arranged sliding frame 10, and a slider 13 is slidably connected in the sliding frame 10. A long screw 12 is threadedly penetrated through the top edge of the slider 13, and a pad 15 for damping cooperation with the upper surface of the first swing arm 5 is rotatably connected at the bottom end of the long screw 12. By using the slider 13 to slide in the sliding frame 10, after the angles of the first swing arm 5 and the second swing arm 9 are adjusted, the slider 13 can be used to slide to realize that the long screw 12 drives the pad 15 to move to the screw rod 11, and then by rotating the long screw 12, the pad 15 is placed on the upper surface of the first swing arm 5, so that the slider 13 can slide on the surface of the long screw 12, and the slider 13 drives the sliding frame 10 and the second swing arm 9 to rise and fall, so that the height adjustment of the positioning block 6 on the second swing arm 9 can be realized, that is, the positioning block 6 for height adjustment can be against the surfaces of lamp shells of different heights, and the surface of the long screw 12 is also threadedly connected with a limiting nut 14 for resisting the bottom edge of the slider 13. After the height of the second swing arm 9 is adjusted, the limiting nut 14 is rotated to tightly fit the bottom surface of the second swing arm 9 and increase the friction force by increasing the pressure. Therefore, the friction between the limiting nut 14 and the second swing arm 9 and the pad 15 and the upper surface of the first swing arm 5 is used to fix the slider 13 on the screw rod 11. The end surfaces of the first swing arm 5 and the second swing arm 9 are penetrated by an auxiliary screw 8 that is threadedly connected to the positioning block 6. The side of the positioning block 6 away from the middle position of the workbench 1 is threadedly connected to an adjusting screw 7 that cooperates with the damping of the workbench 1 surface. The purpose of the auxiliary screw 8 and the adjusting screw 7 is that after the height of the positioning block 6 is adjusted, the auxiliary screw 8 is rotated, and the end face of the auxiliary screw 8 is pressed against the workbench 1 surface to support one end of the second swing arm 9. When the adjusting screw 7 rotates, the end face is tightly pressed against the workbench 1 surface and generates a large friction force, which can further prevent the positioning block 6 on the second swing arm 9 from displacement.

[0027] Working principle: according to the edge shape height of the lamp shell to be processed, the horizontal inclination angle of the first swing arm 5 and the second swing arm 9 and the position relative to the screw rod 11 are adjusted, and then the horizontal relative position of the two positioning blocks 6 on the same side of the workbench 1 is adjusted, and then the position of the slider 13 is adjusted, and the cushion block 15 is used to resist the upper surface of the first swing arm 5, and by rotating the long screw 12, the cushion block 15 is placed on the upper surface of the first swing arm 5, so that the slider 13 can slide on the surface of the long screw 12, and the slider 13 drives the sliding frame 10 and the second swing arm 9 to rise and fall, so as to realize the height adjustment of the positioning block 6 on the second swing arm 9, that is, to ensure that the height-adjusted positioning block 6 can resist the surface of the lamp shell at different heights, and then the lamp shell is placed on the workbench 1, and the lamp shell is lifted by the raised soft pad 4, and the sliding block 3 is moved by rotating the moving screw 2, and the two positioning blocks 6 on the sliding block 3 are driven to move toward the lamp shell until they resist the edge of the lamp shell.

[0028] The wiring diagram of the electric push rod 16 in the present invention belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the electric push rod 16 are not explained in detail.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
