Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, specifically a clamping device for mechanical parts production. Background Technology

[0002] Mechanical parts are an important part of mechanical production. During production, mechanical parts usually need clamping devices to clamp them to prevent them from shifting during processing, thereby improving the processing efficiency.

[0003] Chinese patent publication number "CN222114244U" discloses a "clamping device for manufacturing mechanical parts," comprising a mounting shell, an adjusting component on the top of the mounting shell, a fixing shell within the adjusting component, a sliding groove within the fixing shell, and a fixing component within the fixing shell. The fixing component includes a motor, with a gear fixedly connected to the output shaft of the motor, and one end of the motor output shaft passing through the fixing shell. This invention utilizes the adjusting component to facilitate the adjustment of the angle of the clamped mechanical parts, allowing for machining at different angles. Threaded pins, threaded sleeves, and fixing holes are used to secure the adjusted rotating shaft, preventing angle deviation of the mechanical parts. While this patent uses a relative movement of clamping plates to clamp parts, it lacks a positioning structure, resulting in reduced clamping efficiency and inconsistent clamping lengths, affecting machining accuracy. Therefore, we propose a clamping device for manufacturing mechanical parts. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for the production of mechanical parts, so as to solve the problems mentioned in the background art, which are caused by the lack of a positioning structure, resulting in reduced clamping efficiency of parts and inconsistent clamping lengths, affecting the processing accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for producing mechanical parts, comprising a base plate, a vertical plate, and a track.

A limiting plate is fixedly connected between the right side walls of the connecting plates. A guide frame is fixedly connected to the right side wall of the limiting plate. Clamping plates are rotatably connected to the upper and lower sides inside the guide frame. A torsion spring is provided between the clamping plates and the guide frame. A clamping head is fixedly connected to the right end of the clamping plate, and a ball bearing is rotatably connected to the other end of the clamping plate. A pneumatic telescopic rod is fixedly connected to the left side wall of the vertical plate. The extended end of the pneumatic telescopic rod extends to the inner side of the connecting plate. A guide column is fixedly connected to the telescopic end of the pneumatic telescopic rod, and a tapered column is fixedly connected to the right end of the guide column.

[0006] Preferably, a mounting plate is fixedly connected to the top right side of the base plate, a limiting cylinder is fixedly connected to the upper side of the left side wall of the mounting plate, and an electric push rod is fixedly connected to the left side wall of the mounting plate and inside the limiting cylinder.

[0007] Preferably, a protective pad is adhered to the inner wall of the clamp, and the protective pad is made of rubber.

[0008] Preferably, the tapered column is slidably connected inside the limiting plate, and a connecting rod is fixedly connected to the right end of the tapered column. The right end of the connecting rod passes through the guide frame and extends to the right side of the guide frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This clamping device for producing mechanical parts uses a pneumatic telescopic rod to move a guide column. Simultaneously, the guide column moves a tapered column and a connecting rod, causing the tapered column to contact and press against the ball bearings on the clamping plate. This pressing action causes the other end of the clamping plate to move relative to the guide frame, and the clamping head to hold the part. At the same time, the connecting rod causes a positioning cone to contact the part for positioning, ensuring consistent clamping length. This allows for precise positioning and clamping of the part, improving both clamping efficiency and machining accuracy.

[0014] This clamping device for producing mechanical parts features a limiting post that moves within a limiting cylinder under the action of a tension spring during the clamping process. Simultaneously, a moving frame moves along a track supported by a support plate. At the same time, a pressure roller contacts the clamping plate, squeezing the clamping plate after clamping the part to prevent loosening during the clamping process, thereby improving the stability of the part clamping process.

[0024] Example: Figures 1-5 As shown, this utility model provides a clamping device for the production of mechanical parts, which can position and clamp the parts, improve clamping efficiency and processing accuracy, and improve the stability of the parts during the clamping process. It includes a base plate 100, a vertical plate 200 and a track 300.

A clamp 233 is fixedly connected to the right end of the clamping plate 231, and a ball bearing is rotatably connected to the other end of the clamping plate 231. A pneumatic telescopic rod 240 is fixedly connected to the left side wall of the upright plate 200. The extended end of the pneumatic telescopic rod 240 extends to the inner side of the connecting plate 210. A guide post 241 is fixedly connected to the telescopic end of the pneumatic telescopic rod 240. A conical post 242 is fixedly connected to the right end of the guide post 241. A protective pad 234 made of rubber is adhered to the inner side wall of the clamp 233. The conical post 242 is slidably connected inside the limiting plate 220. The right end of the conical post 242 is fixedly connected to the inner side wall of the clamp 233. A connecting rod 243 is fixedly connected, with its right end passing through the guide frame 230 and extending to the right side of the guide frame 230.

The upright plate 200 is fixedly connected to the top left side of the base plate 100. The guide column 241 is moved by the pneumatic telescopic rod 240. While the guide column 241 moves, it also moves the cone column 242 and the connecting rod 243, so that the cone column 242 contacts and is pressed against the ball bearing on the clamping plate 231. While the cone column 242 is pressing, the other end of the clamping plate 231 moves relative to the guide frame 230 and drives the clamping head 233 to clamp the part. At the same time, the connecting rod 243 drives the positioning cone 244 to contact the part for positioning, ensuring that the clamping length of the part is consistent.

[0027] In summary, this method can position and clamp parts, improving both clamping efficiency and machining accuracy.

[0028] Please refer to it again. Figure 1 Diagram and Figure 5The track 300 is fixedly connected to the outside of the connecting plate 210. A movable frame 310 is slidably connected between the outer sides of the track 300. Pressure rollers 311 are rotatably connected to the upper and lower sides of the right side wall of the movable frame 310. The outer side wall of the pressure rollers 311 is in contact with the clamping plate 231. A support plate 320 is fixedly connected to the bottom left side of the movable frame 310. A limit post 321 is fixedly connected to the right side wall of the support plate 320. The limit post 321 is inserted into the inner cavity of the limit cylinder 111. The end of the limit post 321 is in contact with the telescopic end of the electric push rod 112. The right side wall of the support plate 320 is located at the limit post 321. A tension spring 322 is fixedly connected to the outside of the clamping device. The end of the tension spring 322 is fixedly connected to the left side of the limiting cylinder 111, the track 300 is located on the right side of the upright plate 200. During the clamping process, the limiting post 321 moves within the limiting cylinder 111 under the action of the tension spring 322. At the same time, the moving frame 310 moves under the support of the track 300 through the support plate 320. Meanwhile, the pressure roller 311 contacts the clamping plate 231 and squeezes the clamping plate 231 after clamping the part to prevent the clamping device from loosening during the clamping process.

[0029] In summary, this can improve the stability of parts during the clamping process.

[0030] In practical use, when clamping and processing parts, those skilled in the art place the part between the chucks 233, activate the pneumatic telescopic rod 240 to move the guide column 241. Simultaneously, the guide column 241 moves, causing the tapered column 242 and connecting rod 243 to move, bringing the tapered column 242 into contact with the ball bearings on the clamping plate 231 and applying pressure. While the tapered column 242 is applying pressure, the other end of the clamping plate 231 moves relative to it under the support of the guide frame 230, and the chucks 233 clamp the part. At the same time, the connecting rod 243 moves the positioning cone 244 to contact the part for positioning and clamping. Simultaneously, under the action of the tension spring 322... The limiting post 321 moves within the limiting cylinder 111, while the moving frame 310 moves under the support of the track 300 via the support plate 320. At the same time, the pressure roller 311 contacts the clamping plate 231, squeezing the clamping plate 231 after clamping the part to prevent loosening during the clamping process. After the part is processed, the electric push rod 112 is activated to push the limiting post 321 to move within the limiting cylinder 111, causing the moving frame 310 to drive the pressure roller 311 to release the limiting of the clamping plate 231. The pneumatic telescopic rod 240 resets, causing the conical post 242 to release the squeezing of the clamping plate 231. The part is released from the inside of the chuck 233, and the processing of the part is completed.
