[0002] Automobiles are assembled from multiple parts. During the production of automobile parts, steps such as stamping and welding are used. After some parts are formed by stamping, drilling and polishing are performed on the surface of the parts to further process them, thereby improving the precision of the parts and ensuring smooth installation.

[0003] During the processing of internal pipes and other components in automotive parts, clamping and fixing are necessary to prevent the parts from shaking during processing. However, traditional clamping fixtures result in different center heights for different parts due to their varying sizes. This necessitates adjusting the height of the parts to ensure they are at the same center height during processing operations that use the center position as a reference point, which can affect processing efficiency. To address these issues, a positioning and clamping device for automotive parts processing is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when traditional clamps hold automotive parts of different sizes, the center position of the parts will be at different heights, which will affect the processing.

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] In its specific implementation, such as Figures 1-4 This utility model provides a technical solution: a positioning and clamping device for processing automotive parts, including a base plate 1, an mounting sleeve 3 fixedly installed on the top surface of the base plate 1, support blocks 2 fixedly installed on both sides of the mounting sleeve 3, and a connecting seat 6 fixedly installed on the top surface of the base plate 1; a clamping assembly 5 located inside the mounting sleeve 3; and a blocking assembly 4 located on one side of the clamping assembly 5.

[0032] The clamping assembly 5 includes a support base 56, with second fixing blocks 54 fixedly installed on both sides of the support base 56. A bidirectional threaded rod 53 is threadedly connected to each of the second fixing blocks 54 through threaded holes. A limit ring 55 is fixedly installed on the outer wall of the bidirectional threaded rod 53. A first fixing block 52 is threadedly connected to the other end of the bidirectional threaded rod 53. A pressing block 51 is fixedly installed on one side of the first fixing block 52. A support plate 58 is fixedly installed on the top surface of the support base 56. Spring pins 57 are provided on both the top surface of the support plate 58 and the bottom surface of the pressing block 51. Multiple spring pins 57 are provided and evenly distributed. Multiple spring pins are provided on the support plate 58, and their top ends form V-shaped grooves. The pressing block 51 has grooves corresponding to the support plate 58 and is slidably connected to it. The bidirectional threaded rod 53 is rotatably connected to the support block 53 through a through hole. The outer wall of the support base 56 is slidably connected to the mounting sleeve 3. The support base 56 is slidably connected to the connecting seat 6 through a groove within it.

[0033] When processing the parts, the parts can be passed between the extrusion block 51 and the support plate 58, thereby rotating the bidirectional threaded rod 53 to drive the first fixed block 52 to move, and can drive the extrusion block 51 to move downward. At the same time, the rotation of the bidirectional threaded rod 53 can drive the second fixed block 54 and the support seat 56 to move upward. As the support seat 56 moves upward, it drives the support plate 58 to move upward, and can push the parts to move upward. This allows the spring pins 57 on the surface of the extrusion block 51 and the support plate 58 to contact the surface of the parts, clamping and fixing the parts, and ensuring close contact between the spring pins 57 and the surface of the parts.

[0034] like Figure 4As shown, the blocking assembly 4 includes a sliding sleeve 43, a connecting post 44 is fixedly installed on the outer wall of the sliding sleeve 43, the connecting post 44 is slidably connected to the connecting seat 6 through a groove opened in the connecting seat 6, and the groove is an inclined groove, the sliding sleeve 43 is slidably connected to the supporting seat 56 through a through hole opened on one side, a mounting bracket 41 is slidably installed in the sliding sleeve 43, a fixing pin 42 is slidably installed in the mounting bracket 41 through a groove opened in the mounting bracket 41, a sliding rod 45 is slidably installed in the mounting bracket 41 through a through hole opened in the mounting bracket 41, a pressing plate 47 is fixedly installed at one end of the sliding rod 45, a spring 46 is provided on the outer wall of the sliding rod 45, one side of the spring 46 is fixedly connected to the pressing plate 47, and the other end of the spring 46 is fixedly connected to the mounting bracket 41;

[0035] During the upward movement of the support base 56, the movement of the support base 56 can drive the sliding sleeve 43 to move. At the same time, since the connecting posts 44 on both sides of the sliding sleeve 43 are slidably connected to it through the inclined grooves opened in the connecting base 6, the connecting posts 44 are gradually slid into the support base 56 under the pressure of the connecting base 6 during the upward movement of the sliding sleeve 43. This causes the mounting bracket 41 to move and the pressing plate 47 to move, so that one side of the pressing plate 47 contacts one end of the component and compresses the spring 46. The pressing of the pressing plate 47 further restricts the component and further positions it. During use, the fixing pin 42 can be pulled out according to the length of the component, so that the mounting bracket 41 can be slid out to extend a certain length. Then, the fixing pin 42 can be reinserted into the mounting bracket 41 and the sliding sleeve 43 to fix the mounting bracket 41.

[0036] Working principle: When processing parts, the parts can be passed between the extrusion block 51 and the support plate 58. Rotating the bidirectional threaded rod 53 moves the first fixed block 52, causing the extrusion block 51 to move downwards. Simultaneously, the rotation of the bidirectional threaded rod 53 moves the second fixed block 54 and the support base 56 upwards. As the support base 56 moves upwards, the support plate 58 moves upwards, pushing the parts upwards. This causes the spring pins 57 on the surfaces of the extrusion block 51 and the support plate 58 to contact the surface of the parts, clamping and fixing them. The spring pins 57 maintain tight contact with the part surface. During the upward movement of the support base 56, the movement of the support base 56 also moves the sliding sleeve 43. As the sliding sleeve 43 moves upward, the connecting posts 44 on both sides of the sliding sleeve 43 are slidably connected to it through the inclined grooves opened in the connecting seat 6. As the sliding sleeve 43 moves upward, the connecting posts 44 are squeezed by the connecting seat 6 and gradually slide into the support seat 56, thereby driving the mounting bracket 41 to move and driving the pressing plate 47 to move. This causes one side of the pressing plate 47 to contact one end of the component and compress the spring 46. The pressing of the pressing plate 47 further restricts the component and further positions it. During use, the fixing pin 42 can be pulled out according to the length of the component, so that the mounting bracket 41 can be slid out to extend a certain length. Then, the fixing pin 42 can be reinserted into the mounting bracket 41 and the sliding sleeve 43 to fix the mounting bracket 41.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
