Description

Technical Field

[0001] The present application relates to the technical field of automobile production jigs, and in particular to a high-strength automobile limiting and fixing mechanism. Background Art

[0002] In order to facilitate the processing of automobile parts, the existing fixing mechanism usually fixes the automobile parts and then drives the automobile parts to rotate, thereby facilitating the processing.

[0003] In this regard, China's patent application number is CN202120655588.X, which discloses an adjustable limit fixing mechanism for automobiles. This scheme mainly generates magnetism by connecting the electromagnetic coil to the power supply. Multiple stainless steel clamping rods are attracted by the electromagnetic coil and inserted into the clamping slot to prevent the disc from rotating. After the disc is stuck, the automobile parts are limited to prevent the automobile parts from rotating during the processing. When the automobile parts need to be flipped over again, the power supply of the electromagnetic coil is disconnected, the spring is not subjected to force, and the stainless steel clamping rod is pulled out of the clamping slot through its own elasticity. The motor continues to run, which can drive the automobile parts to flip over. After flipping the automobile parts, the fixing mechanism limits the automobile parts, effectively ensuring the stability of the automobile parts during the processing.

[0004] However, in the process of implementing the technical solution in the embodiments of the present application, the inventor of the present application found that the above technology has at least the following technical problems:

[0005] 1. After the lever is limited, the parts can no longer be rotated and adjusted, affecting the operation;

[0006] 2. The number of clamps is limited, and the parts can only be restricted to a few specific angles, and the fixing effect is limited. Utility Model Content

[0009] In a specific embodiment, the telescopic frame includes a frame and a slide, the slide translates on the frame, and the two top cones are respectively arranged on the frame and the slide.

[0010] In a specific implementation manner, a slide rail is fixedly connected to the frame, the slide bracket is slidably connected to the slide rail, and a locking rod is screwed to the slide bracket.

[0011] In the above implementation process, the slide moves along the slide rail to adjust the distance between the two top cones to adapt to automobile parts of different lengths. After the adjustment is completed, the locking rod is rotated, and the locking rod moves downward and presses against the slide rail to achieve position locking.

[0015] In a specific embodiment, the top cone is rotatably connected to the swivel seat.

[0016] In the above implementation process, the automobile part is pressed against the two top cones, and the two chucks select one of them to clamp the automobile part according to the situation, so that the automobile part is driven by the driving part A or the driving part B to rotate. In this embodiment, the chuck is pneumatically controlled, and the two chucks are linked. When one chuck is clamped, the other chuck is loosened.

The driving part B with a small transmission ratio can quickly drive the automobile parts to rotate, while the driving part A with a large transmission ratio can slowly drive the automobile parts to rotate and self-lock at any time, which is more flexible than the prior art.

[0027] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0028] See also Figure 1-Figure 4The present application provides a high-strength automobile position limiting and fixing mechanism, including a telescopic frame 10, with top cones 20 respectively arranged at both ends of the telescopic frame 10, an automobile part 30 being pressed tightly between the two top cones 20, a clamping mechanism 40 being arranged on the periphery of the top cone 20, the clamping mechanism 40 being movably clamped on the outer circle of the automobile part 30, and a driving member A50 and a driving member B60 being respectively connected to the two clamping mechanisms 40 by power, the transmission ratio of the driving member A50 being greater than 30, and the transmission ratio of the driving member B60 being less than 5. Among them, the two telescopic frames 10 with the two top cones 20 press and fix the automobile part 30 tightly, and the two clamping mechanisms 40 clamp and release to switch the linkage between the automobile part 30 and the driving member A50 or the driving member B60, the driving member B60 with a small transmission ratio can quickly drive the automobile part 30 to rotate, and the driving member A50 with a large transmission ratio can realize slow driving of the automobile part 30 to rotate, and self-lock at any time, which is more flexible than the existing technology position limiting.

[0029] See also Figure 1-Figure 4 The telescopic frame 10 includes a frame 11 and a slide 12. The slide 12 translates on the frame 11. Two top cones 20 are respectively arranged on the frame 11 and the slide 12. A slide rail 13 is fixedly connected to the frame 11. The slide 12 is slidably connected to the slide rail 13. A locking rod 14 is screwed on the slide 12. The slide 12 moves along the slide rail 13 to adjust the distance between the two top cones 20 to adapt to automobile parts 30 of different lengths. After the adjustment is completed, the locking rod 14 is rotated, and the locking rod 14 moves downward and presses against the slide rail 13 to achieve position locking.

[0030] See also Figure 1-Figure 4 The frame 11 is rotatably connected with a screw rod 15, which is screwed to the carriage 12. The screw rod 15 is rotated to push the carriage 12 to move, so as to tighten the automobile part 30.

[0031] See also Figure 1-Figure 4 The clamping mechanism 40 includes a swivel seat 41 and a chuck 42. The two swivel seats 41 are rotatably connected to the frame 11 and the slide 12 respectively, and the chuck 42 is installed on the swivel seat 41. The top cone 20 is rotatably connected to the swivel seat 41. The automobile part 30 is pressed against the two top cones 20, and the two chucks 42 select one of them according to the situation to clamp the automobile part 30, so that the automobile part 30 is driven by the driving part A50 or the driving part B60 to rotate. In this embodiment, the chuck 42 is pneumatically controlled, and the two chucks 42 are linked. When one chuck 42 is clamped, the other chuck 42 is loosened. Compared with the screw-type clamping method in the comparative document, the pneumatic chuck 42 has higher fixing strength and better concentricity.

[0032] See also Figure 1-Figure 4The driving part A50 includes a motor A51, a worm gear 52 and a worm 53. The motor A51 drives the corresponding rotating seat 41 to rotate through the meshing of the worm gear 52 and the worm 53. The driving part B60 is a motor B, and the output end of the motor B is connected to the corresponding rotating seat 41 shaft. The motor A51 achieves a slow rotation effect through the deceleration of the worm gear 52 and the worm 53, and has a self-locking effect, realizing the coexistence of limiting and adjusting. The motor B adopts a direct drive mode, which can quickly rotate the automobile part 30 and improve work efficiency.

[0033] The working principle of the high-strength automobile limit fixing mechanism is: the screw rod 15 is rotated to push the slide 12 to move inward, and the automobile part 30 is fixed by two top cones 20. When the automobile part 30 needs to be rotated quickly, the motor B directly drives the corresponding rotating seat 41 to rotate, and the chuck 42 on the rotating seat 41 clamps the automobile part 30 to drive the automobile part 30 to rotate quickly. When the limited position is reached, the chuck 42 on the motor B is loosened, and the chuck 42 on the motor A51 is clamped. As a result, the motor A51 drives the worm gear 52 and the worm gear 52 to rotate. The deceleration of the rod 53 slowly drives the automobile part 30 to rotate, and the limit can be achieved at any time. In summary, the two telescopic frames 10 carry the two top cones 20 to tighten and fix the automobile part 30, and the two clamping mechanisms 40 clamp and release to switch the linkage between the automobile part 30 and the driving part A50 or the driving part B60. The driving part B60 with a small transmission ratio can quickly drive the automobile part 30 to rotate, while the driving part A50 with a large transmission ratio can slowly drive the automobile part 30 to rotate and self-lock at any time, which is more flexible than the existing technology.
