Description

Technical Field

[0001] This application relates to the field of positioning technology, and more specifically, to a positioning mechanism for processing and modifying mechanical equipment. Background Technology

[0002] A positioning mechanism for machining and modification of mechanical equipment is a device used to precisely position a workpiece or component to be modified during machining or modification of mechanical equipment. It ensures the stability of the workpiece's relative position to tools and equipment during machining or modification by limiting the workpiece's displacement, providing an accurate reference for processes such as drilling, welding, and assembly, and guaranteeing the precision and stability of machining and modification.

[0003] In the processing of cylindrical materials, traditional positioning mechanisms have practical problems in terms of adaptability and stability. In actual operation, some positioning mechanisms are difficult to flexibly adapt to cylindrical materials of different diameters, and uneven force may cause slight displacement of the material during processing, affecting the accuracy of processing and making it difficult to meet diverse processing positioning needs.

[0004] In view of this, this application proposes a positioning mechanism for processing and modifying mechanical equipment. Utility Model Content

[0007] The positioning component includes clamping rods located at the four corners of the upper surface of the support plate. Rotating rods are rotatably inserted into each of the four corners of the support plate, and the upper end of the rotating rod is fixedly inserted into the other end of the clamping rod.

Detailed Implementation

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-3This application provides a positioning mechanism for processing and modifying mechanical equipment, including a support plate 1. Positioning components 2 are provided at each of the four corners of the support plate 1. A double-threaded rod 6 with opposite thread directions is provided below the support plate 1. The two ends of the outer wall of the double-threaded rod 6 are connected to a moving block 7 by threaded rotation. The upper end face of the moving block 7 is in contact with the lower end face of the support plate 1. Rotating grooves 8 are provided on both sides of the moving block 7. The positioning components 2 include clamping rods 201 located at the four corners of the upper end face of the support plate 1. A fixing rod 202 is fixedly inserted into the inside of one end of the clamping rod 201. Anti-slip cylinders 203 are fixedly sleeved at the upper and lower ends of the fixing rod 202. The four clamping rods 201 on the upper end of the support plate 1 are located in pairs on both sides of the conveying mechanism. This distribution can form an encirclement of the cylindrical material from both sides, which is beneficial for clamping the material from all directions.

[0021] Rotating rods 204 are rotatably inserted into each of the four corners of the support plate 1. The upper end of the rotating rod 204 is fixedly inserted into the other end of the clamping rod 201. An extension rod 205 is fixedly sleeved at the lower end of the rotating rod 204. A swing rod 206 is rotatably connected to the lower end of the extension rod 205 away from the rotating rod 204. The other end of the swing rod 206 extends into the rotating groove 8. Connecting shafts 207 are rotatably inserted into both ends of the swing rod 206. The two connecting shafts 207 are rotatably connected to the rotating groove 8 and the other end of the extension rod 205, respectively. A pair of fixing plates 3 are fixedly connected to the lower end face of the support plate 1. A servo motor 4 is fixedly connected to the outer wall of one side of the fixing plate 3. Both ends of the double-headed threaded rod 6 are rotatably connected to the fixing plate 3. The servo motor 4 is connected to the fixed plate 3 and fixedly connected to the double-threaded rod 6. The servo motor 4 drives the double-threaded rod 6 to rotate, and the reverse threads at both ends drive the moving block 7 to move closer. Through the linkage of the swing rod 206 and the extension rod 205, the four clamping rods 201 rotate synchronously. The anti-slip cylinder 203 on the fixed rod 202 pushes the cylindrical material to the center of the support plate 1 and clamps it, ensuring that the material is stable in position during processing and avoiding displacement that affects processing accuracy. The synchronous action design of the four clamping rods 201 can adapt to cylindrical materials of different diameters. Stable clamping is achieved by uniform force application, meeting the positioning requirements of various processing scenarios. The whole process is completed by mechanical linkage, and the structure is reliable.

[0022] Assembly plates 5 are fixedly connected to both sides of the upper end of the support plate 1. The assembly plates 5 on both sides of the upper end of the support plate 1 are installed on the conveying mechanism below the mechanical equipment processing and modification device, so as to facilitate the stable connection of the entire device with the conveying mechanism and provide a solid support foundation for the subsequent positioning and fixing of the cylindrical material.

[0023] Working principle: The operator installs the assembly plates 5 on both sides of the upper end of the support plate 1 onto the conveying mechanism below the mechanical equipment processing and modification device. The four clamping rods 201 on the upper end of the support plate 1 are located in pairs on both sides of the conveying mechanism. When a cylindrical material is conveyed to the mechanical equipment processing and modification device, the servo motor 4 is started. The servo motor 4 drives the output end to rotate, which in turn drives the double-ended threaded rod 6 to rotate. Since the pitch of the threads at both ends of the double-ended threaded rod 6 is the same but the thread direction is opposite, the rotation of the double-ended threaded rod 6 causes the moving blocks 7 on the outer walls at both ends to move closer to each other. Since the swing rods 206 in the rotating grooves 8 at both ends of the moving blocks 7 are rotatably connected by the connecting shaft 207, and the other end of the swing rod 206 is rotatably connected to the extension rod 205 by another connecting shaft 207, the movement of the moving blocks 7 will... Pulling the swing rods 206 on both sides causes them to swing, and simultaneously the other end of the swing rods 206 pulls the extension rod 205. Under the limit of the rotating rod 204, the extension rod 205 rotates. The rotation of the extension rod 205 drives the rotating rod 204 and the clamping rod 201 to rotate synchronously, so that the fixed rods 202 at one end of the four clamping rods 201 move closer to each other until the anti-slip cylinders 203 on the four fixed rods 202 push the cylindrical material to the center position of the support plate 1, and clamp the cylindrical material, thereby achieving the positioning and fixing effect. After the processing and modification are completed, the output end of the servo motor 4 rotates in the opposite direction, driving the double-headed threaded rod 6 to rotate in the opposite direction. The two moving blocks 7 move away from each other, causing the swing rods 206 and the extension rod 205 to swing in the opposite direction, thereby driving the four clamping rods 201 to reverse. The anti-slip cylinders 203 on the fixed rods 202 move away from the cylindrical material, and the worker can then remove the cylindrical material.

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.
