[0001] This utility model relates to the field of automotive parts inspection technology, specifically a fixing device for automotive parts inspection. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the car. Automotive parts need to meet design requirements, aesthetic requirements, etc., and samples need to be placed on an inspection table to determine whether the parts are qualified through careful inspection.

[0003] Traditionally, when inspecting the appearance of automotive parts, users need to hold the parts by hand and hold them under a light source to inspect for defects. However, when encountering heavy parts, it is difficult for users to hold them, which affects the actual inspection results. To address this issue, we have proposed a fixing device for automotive parts inspection. Utility Model Content

[0007] Preferably, both the moving friction plate and the fixed friction plate are designed with annular structure, and the sides of the moving friction plate adjacent to the fixed friction plate are provided with friction patterns to enhance the friction between them.

[0008] Preferably, the drive shaft has grooves for passing through both ends of the connecting rod, and the two ends of the grooves are sealed.

[0009] Preferably, the side of the slider adjacent to the ball joint is provided with an arc-shaped protrusion, which can contact the ball end of the ball joint.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This fixing device for inspecting automotive parts has a clamping structure on the base. The surface of the threaded rod included in the clamping structure has two sections of threads with opposite helical directions that are symmetrical about the center of the threaded rod. These threads connect two sliding rods and clamping plates. Therefore, after the threaded rod rotates, it can drive the two clamping plates to slide synchronously toward the center of the base, so as to clamp the automotive parts in the center position of the base and align them with the lighting lamp directly above it, thereby facilitating the subsequent inspection process.

[0015] 2. This fixing device for automotive parts inspection uses an adjustment component to adjust the state of the threaded rod. The moving friction plate and the fixed friction plate work together with the spring force to form a certain friction force, thereby achieving the purpose of locking the threaded rod. This ensures that the entire clamping structure has a good clamping and fixing effect on automotive parts to meet actual inspection requirements. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 A fixing device for inspecting automotive parts includes: a base 1, a column 2 fixedly installed on the side of the base 1, a lighting lamp 3 provided on the side of the column 2, and a clamping structure 4 and an adjustment component 5 provided on the base 1; the column 2 has an L-shaped structure design, and the lighting lamp 3 is located directly above the center of the base 1.

[0024] The clamping structure 4 includes a threaded rod 44 rotatably disposed inside the base 1 and a slide rod 43 slidably connected to the base 1. A clamping plate 41 is fixedly installed at the end of the slide rod 43. A soft plate 42 is provided on the side of the clamping plate 41 to reduce damage to the parts when the clamping plate 41 clamps the automotive parts. Two sections of threads with opposite helical directions are symmetrically arranged on the threaded rod 44 with its center. The threaded rod 44 is connected to the two slide rods 43 through the two sections of threads, so that the two slide rods 43 can push the two clamping plates 41 to slide synchronously toward the center of the base 1.

[0025] The adjusting assembly 5 includes a drive shaft 53 rotatably disposed inside the base 1, a fixed friction plate 54 fixedly mounted on the inner wall of the base 1 cavity, a worm gear 56 fixedly mounted on the end of the drive shaft 53, and a worm wheel 57 fixedly mounted on the threaded rod 44. A turntable 51 is fixedly mounted on the end of the drive shaft 53 passing through the base 1, and a ball joint rod 510 is slidably disposed inside the drive shaft 53. The turntable 51 has a cavity for accommodating the ball end of the ball joint rod 510. A connecting rod 58 is fixedly mounted on the end of the ball joint rod 510. An arc-shaped protrusion is provided on the side of the slider 52 adjacent to the ball joint rod 510, which can contact the ball end of the ball joint rod 510. A moving friction plate 55 is fixedly mounted on the end of the connecting rod 58, and a first spring 59 is fixedly mounted on the side of the connecting rod 58. The end of the first spring 59 away from the connecting rod 58 is fixedly connected to the drive shaft 53. A groove is provided for the two ends of the connecting rod 58 to pass through. The two ends of the groove are sealed. A sliding button 52 is slidably arranged on the turntable 51. A second spring 511 is fixedly installed on the side of the sliding button 52. The end of the second spring 511 is also fixedly connected to the turntable 51. The worm gear 56 is meshed with the worm wheel 57 for transmission. The moving friction plate 55 and the fixed friction plate 54 are both designed with annular structure. The sides of the moving friction plate 55 and the fixed friction plate 54 adjacent to each other are provided with friction texture to enhance the friction between them. A guide rod 512 is fixedly installed on the inner wall of the turntable 51. The sliding button 52 is also slidably connected to the guide rod 512. The second spring 511 is located in the inner cavity of the guide rod 512, and the axis of the second spring 511 coincides with the axis of the guide rod 512. This can prevent the second spring 511 from being over-deformed, thereby ensuring the performance of the second spring 511.

[0026] Working principle: When fixing automotive parts for testing, the parts are placed between two clamping plates 41, and the sliding button 52 is pushed to slide on the turntable 51, causing the arc-shaped protrusion on the side of the sliding button 52 to be misaligned with the ball end of the ball joint rod 510. The connecting rod 58 fixed to the end of the ball joint rod 510 is further connected to the drive shaft 53 using the first spring 59, and the end of the connecting rod 58 passing through the drive shaft 53 is also fixed with a dynamic friction plate 55. The arc-shaped protrusion of the sliding button 52 and the ball joint rod 510 are misaligned. After opening, under the elastic force of the first spring 59, the ball joint 510, connecting rod 58, and moving friction plate 55 are pulled to slide, so that a gap is formed between the moving friction plate 55 and the fixed friction plate 54 fixed inside the base 1. At this time, the turntable 51 is rotated by the sliding button 52, and the transmission shaft 53 fixedly connected to the turntable 51 rotates together. The worm 56 fixed at the end of the transmission shaft 53 and the worm wheel 57 fixed on the threaded rod 44 will mesh and transmit power. Driven by the worm gear 57, the threaded rod 44 rotates synchronously. The threaded rod 44 has two sections of threads with opposite helical directions on its surface, which connect to two sliding rods 43. After the threaded rod 44 rotates, it can drive the two sliding rods 43 and the two clamping plates 41 to slide towards the center of the base 1, so as to clamp and fix the car parts in the center position of the base 1, so as to align the car parts with the lighting lamp 3 on the column 2 and turn on the lighting lamp 3, so as to facilitate the user to inspect the outer surface of the car parts. When the sliding button 52 is released, under the elastic force of the second spring 511, which is fixedly connected to the sliding button 52 and the turntable 51 at both ends, the sliding button 52 slides towards the ball head rod 510. Under the compression of the arc-shaped protrusion of the sliding button 52, the ball head rod 510 and the moving friction plate 55 slide towards the fixed friction plate 54, eliminating the gap. The moving friction plate 55 and the fixed friction plate 54 are in close contact, thereby forming a certain friction force, restricting the rotation of the drive shaft 53, and thus locking the overall structure.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
