Description

Technical Field

[0001] This utility model relates to the field of small table processing technology, specifically a positioning device for processing push-button type automotive small tables. Background Technology

[0002] In today's automotive interior accessories industry, push-button switch car tray tables are becoming increasingly popular. They not only provide passengers with convenient space while traveling, meeting their needs for dining, working, and other activities, but also become a key element in enhancing the quality of car interiors due to their exquisite appearance.

[0003] Traditional positioning devices for processing use a single-sided extrusion clamping method. However, this method has significant drawbacks when dealing with lightweight automotive small tables that require strict aesthetic standards. Due to the table's light weight, the friction generated by single-sided extrusion is insufficient to stabilize it in the ideal position. This often results in the table's center deviating from the positioning device's center. Consequently, when grinding, painting, or other processing equipment is running, the table is prone to slipping due to uneven force, significantly reducing processing quality. Furthermore, single-sided extrusion causes an imbalance of force on both sides of the table. For small tables made of new lightweight composite materials, the sidewall strength is limited, and uneven force can easily cause sidewall dents and deformation, severely affecting the table's appearance and compromising its overall aesthetics. Therefore, a push-button switch-type positioning device for processing automotive small tables is urgently needed to solve these problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a positioning device for processing push-button type automotive small table, so as to solve the problem mentioned in the background art that the traditional single-sided extrusion clamping positioning method makes it difficult for the center position of the table to correspond with the center of the positioning device after the small table is fixed. As a result, the small table is prone to uneven force and slippage when the surface of the small table is processed in the subsequent process. Secondly, the single-sided extrusion positioning device may also cause uneven force on both sides of the lower table, resulting in deformation or damage to the side wall of the table.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for processing push-button type automotive small table, including a main frame, wherein the inner wall of the main frame is provided with a clamping and positioning component;

[0006] The clamping and positioning assembly includes a sliding frame, which is slidably connected to the inner wall of the main frame. A rotating column is rotatably connected to the inner wall of the sliding frame. A spur gear is fixedly connected to the surface of the rotating column. Two symmetrically arranged clamping plates are slidably connected to the top surface of the sliding frame. A rack is fixedly connected to the bottom surface of the clamping plates. The surfaces of the spur gears are meshed with the side walls of the two clamping plates.

[0007] In this technical solution, the clamping and positioning components allow the rotating column to easily clamp and position the small tabletops to be processed on the surfaces of the two clamping plates towards the center of the sliding frame. This ensures that the center of the small tabletop corresponds to the center of the sliding frame after clamping, thus ensuring that the force on the small tabletop is evenly transmitted to the sliding frame during processing. This prevents slippage due to uneven force on the small tabletop surface, which could affect the stability of the processing. Furthermore, the bidirectional synchronous clamping method ensures that the clamping force on both sides of the small tabletop is relatively uniform when clamped, avoiding the situation where the side walls of the small tabletop are damaged due to unilateral squeezing.

[0008] Preferably, the top surface of the main frame has two sliding holes, and the surface of the sliding frame is fixedly connected with a plurality of positioning threaded posts. The surfaces of two positioning threaded posts are movably sleeved with the inner wall of the same sliding hole. The surface of the positioning threaded posts is threaded with a threaded head, and the bottom surface of the threaded head abuts against the top surface of the main frame.

[0009] In this technical solution, the sliding hole facilitates the positioning of the sliding frame's forward and backward movement, ensuring that the small table remains in a straight line during forward and backward adjustment, thus preventing the sliding frame from rotating and affecting processing accuracy.

[0010] Preferably, the inner wall of the sliding frame is rotatably connected to a control threaded column, the surface of the control threaded column is fixedly connected to a first bevel gear, and the surface of the rotating column is fixedly connected to a second bevel gear, wherein the first bevel gear and the second bevel gear are meshed together.

[0011] In this technical solution, by setting a control threaded post, the rotation of the control threaded post can drive the rotation of the rotating post, thereby improving the convenience of operation.

[0012] Preferably, the inner wall of the sliding frame is fixedly connected to two limiting plates, the side wall of the rack is provided with limiting holes, and the side wall of the limiting plate is slidably connected to the inner wall of the limiting hole.

[0013] In this technical solution, by setting a limiting plate and a limiting hole to work together, it is easy to limit the clamping plate and ensure that the two clamping plates remain parallel when moving left and right.

[0014] Preferably, the surface of the control threaded column is threaded with a threaded ring, and the sidewall of the threaded ring abuts against the sidewall of the sliding frame.

[0015] In this technical solution, the threaded ring facilitates the limiting of the control threaded column. Twisting the threaded ring clockwise causes the side wall of the threaded ring to press against the side wall of the sliding frame, thereby fixing the control threaded column.

[0016] Preferably, the bottom surface of the main frame is provided with an installation groove, and the inner wall of the installation groove is provided with a counterweight.

[0017] In this technical solution, the use of counterweights facilitates the positioning of the main frame.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The clamping and positioning components allow the rotating column to easily clamp and position the small tables to be processed on the surfaces of the two clamping plates towards the center of the sliding frame. This ensures that the center of the small table corresponds to the center of the sliding frame after clamping, allowing the force on the small table to be evenly transmitted to the sliding frame during processing. This prevents slippage due to uneven force on the small table surface, which could affect the stability of the processing. Furthermore, the bidirectional synchronous clamping method ensures that the clamping force on both sides of the small table is relatively uniform when it is clamped, avoiding the damage to the side walls of the small table caused by unilateral squeezing.

[0025] 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.

[0026] Please see Figure 1-4 This utility model provides a positioning device for processing push-button type car small table, including a main frame 1. A clamping and positioning assembly 2 is provided on the inner wall of the main frame 1. The clamping and positioning assembly 2 includes a sliding frame 201, which is slidably connected to the inner wall of the main frame 1. A rotating column 202 is rotatably connected to the inner wall of the sliding frame 201. A spur gear 203 is fixedly connected to the surface of the rotating column 202. Two symmetrically arranged clamping plates 204 are slidably connected to the top surface of the sliding frame 201. A rack 205 is fixedly connected to the bottom surface of the clamping plates 204. The surfaces of the spur gears 203 are meshed with the side walls of the two clamping plates 204. The positioning device is positioned by the clamping and positioning assembly. The positioning component 2 allows the rotating column 202 to rotate, facilitating the clamping and positioning of the small table to be processed on the surfaces of the two clamping plates 204 towards the center position of the sliding frame 201. This ensures that the center position of the small table corresponds to the center position of the sliding frame 201 after the small table is clamped, thereby ensuring that the force on the small table is evenly transmitted to the sliding frame 201 when processing the surface of the small table. This prevents slippage due to uneven force on the surface of the small table, which would affect the stability of the processing. Furthermore, the bidirectional synchronous clamping method ensures that the clamping force on the left and right sides of the small table is relatively uniform when it is clamped, avoiding the situation where the side wall of the small table is damaged due to unilateral squeezing.

[0027] Furthermore, two sliding holes 211 are provided on the top surface of the main frame 1. Multiple positioning threaded posts 212 are fixedly connected to the surface of the sliding frame 201. The surfaces of the two positioning threaded posts 212 are movably sleeved with the inner wall of the same sliding hole 211. The surfaces of the positioning threaded posts 212 are threadedly connected with threaded heads 213. The bottom surface of the threaded heads 213 abuts against the top surface of the main frame 1. The sliding holes 211 facilitate the positioning of the sliding frame 201's forward and backward movement, thereby ensuring that the small table remains in a straight line when it moves forward and backward, and preventing the sliding frame 201 from rotating during forward and backward movement, which would affect the processing accuracy.

[0028] Furthermore, a control threaded post 207 is rotatably connected to the inner wall of the sliding frame 201. A first bevel gear 208 is fixedly connected to the surface of the control threaded post 207, and a second bevel gear 209 is fixedly connected to the surface of the rotating post 202. The first bevel gear 208 and the second bevel gear 209 are meshed together. By setting the control threaded post 207, the rotating post 202 can be driven to rotate when the control threaded post 207 rotates, thereby improving the convenience of operation.

[0029] Furthermore, two limiting plates 206 are fixedly connected to the inner wall of the sliding frame 201, and a limiting hole 216 is opened on the side wall of the rack 205. The side wall of the limiting plate 206 is slidably connected to the inner wall of the limiting hole 216. By setting the limiting plate 206 and the limiting hole 216 to cooperate with each other, it is convenient to limit the clamping plate 204 and ensure that the two clamping plates 204 remain parallel when moving left and right.

[0030] Furthermore, the surface of the control threaded post 207 is threaded with a threaded ring 210. The side wall of the threaded ring 210 abuts against the side wall of the sliding frame 201. The threaded ring 210 facilitates the limiting of the control threaded post 207. Tightening the threaded ring 210 clockwise will cause the side wall of the threaded ring 210 to press against the side wall of the sliding frame 201, thereby fixing the control threaded post 207.

[0031] Furthermore, the bottom surface of the main frame 1 is provided with an installation groove 214, and the inner wall of the installation groove 214 is provided with a counterweight 215. The counterweight 215 facilitates the positioning of the main frame 1.

[0032] Working principle: During use, rotating the threaded column 207 will drive the rotating column 202 to rotate. The rotation of the rotating column 202 will facilitate the clamping and positioning of the small table to be processed on the surface of the two clamping plates 204 towards the center position of the sliding frame 201. This ensures that the center position of the small table corresponds to the center position of the sliding frame 201 after the small table is clamped. This allows the force on the small table to be evenly transmitted to the sliding frame 201 when processing the surface of the small table, avoiding slippage due to uneven force on the surface of the small table, which would affect the stability of the processing. Secondly, the bidirectional synchronous clamping method ensures that the clamping force on the left and right sides of the small table is more uniform when it is clamped, avoiding the situation where the side wall of the small table is damaged by unilateral squeezing.
