[0002] A pin is a standardized mechanical part, typically a cylindrical rod-shaped structure, primarily used to connect mechanical components or transmit power, while allowing relative rotation or oscillation between the connected parts. It is widely used in machinery, automobiles, aerospace, construction machinery, agricultural machinery, and other fields, and is one of the key components in mechanical transmission and structural connections.

[0003] For example, the utility model patent with announcement number CN217832954U discloses an automatic pin grinding device, including a pin storage box. The pin storage box has a pin storage cavity inside, and pin bodies are evenly arranged inside the pin storage cavity. An L-shaped groove is provided on one side of the pin storage box, and a through hole is provided inside the pin storage box at the bottom end of the L-shaped groove. The L-shaped groove is connected to the through hole. A push plate is installed inside the L-shaped groove. A fixing column is installed on one side of the pin storage box, and an electric telescopic rod is installed on the side of the fixing column near the pin storage box.

[0004] However, the grinding groove size is fixed in this utility model, so it can only be used to grind pins of the same specific size, and its application range is relatively small. Utility Model Content

[0011] Beneficial effects

[0012] This utility model provides a grinding device for processing pins, which has the following beneficial effects:

[0013] 1. The device is equipped with a worktable, on which a cover can be installed. A housing can be installed inside the housing for grinding the pins. A U-shaped plate can be installed inside the U-shaped plate for installing a hinge plate. A lifting assembly can be installed so that the lifting assembly can move the hinge plate to swing. The hinge plate can also move a pair of clamping plates to swing, thus clamping and fixing pins of different diameters. This effectively prevents the pins from rolling during grinding, which would affect the grinding effect.

[0014] 2. A first cylinder is installed. When the first cylinder is started, the extension and retraction end of the first cylinder drives the lifting rod to rise and fall, thereby driving the fixed seat and the lifting block to rise and fall. During the rising and falling of the lifting block, one end of the hinge plate can slide on the inclined surface of the lifting block, thereby driving the hinge plate to swing, which in turn drives the clamping plate to swing. This allows the position of the rotating roller and the clamping plate to be adjusted to clamp and fix the pin. A motor is installed. When the motor is started, it drives the rotating roller to rotate, which in turn drives the pin to rotate, so that the various surfaces of the pin can be polished. Attached Figure Description

Wherein, directional terms such as "upper" and "lower" mentioned herein are used in conjunction with... Figure 1 The orientation is used as a reference.

[0020] Please see Figures 1-3 This utility model provides a technical solution: a grinding device for pin processing, including a worktable 1 and a housing 2, the housing 2 being fixedly installed on the worktable 1, and also including a U-shaped plate 4, a clamping plate 10 and a lifting assembly; the number of U-shaped plates 4, clamping plates 10 and lifting assemblies are all a pair, a base plate 3 is fixedly installed on the worktable 1, a pair of U-shaped plates 4 are fixedly installed on the base plate 3, a pair of hinge plates 9 are hinged in each pair of U-shaped plates 4, one end of the pair of clamping plates 10 is hinged to the hinge plate 9, the lifting assembly is installed in the U-shaped plates 4, and the bottom of the pair of hinge plates 9 is movably connected to the lifting assembly.

[0021] With the workbench 1 installed, a cover 15 can be installed on the workbench 1. With the housing 2 installed, the pin can be ground inside the housing 2. With the U-shaped plate 4 installed, a hinge plate 9 can be installed inside the U-shaped plate 4. With the lifting component installed, the lifting component can move the hinge plate 9 to swing. With the hinge plate 9 installed, the swinging of the hinge plate 9 can move a pair of clamping plates 10 to swing, thereby clamping and fixing pins of different diameters. This can effectively prevent the pin from rolling during grinding, which would affect the grinding effect.

[0022] Furthermore, the lifting assembly includes a first cylinder 5, a lifting rod 7 is fixedly installed at the telescopic end of the first cylinder 5, a fixed seat 11 is fixedly installed at the top of the lifting rod 7, a rotating roller 12 is rotatably installed inside the fixed seat 11, a motor 17 for driving the rotating roller 12 to rotate is fixedly installed on one side plate of the fixed seat 11, a lifting block 8 is fixedly installed on the lifting rod 7, the lifting block 8 is frustum shaped, and a pair of hinge plates 9 are slidably connected at the bottom to the inclined surface of the lifting block 8.

[0023] The first cylinder 5 is installed and started. The extension and retraction end of the first cylinder 5 drives the lifting rod 7 to rise and fall, thereby driving the fixed seat 11 and the lifting block 8 to rise and fall. During the rising and falling of the lifting block 8, one end of the hinge plate 9 can slide on the inclined surface of the lifting block 8, thereby driving the hinge plate 9 to swing, which in turn drives the clamping plate 10 to swing. This allows the position of the rotating roller 12 and the clamping plate 10 to be adjusted to clamp and fix the pin. The motor 17 is installed and started, which drives the rotating roller 12 to rotate, thereby driving the pin to rotate, so as to facilitate the grinding of each surface of the pin.

[0024] Furthermore, a fixing sleeve 6 is fixedly installed inside the U-shaped plate 4, and the lifting rod 7 is slidably connected to the fixing sleeve 6.

[0025] By installing the fixing sleeve 6, the lifting rod 7 can be limited, so that the lifting rod 7 can maintain vertical lifting.

[0026] Furthermore, a second cylinder 13 is fixedly installed on the top of the housing 2, and a mounting cover 15 is fixedly installed on the telescopic end of the second cylinder 13. A grinding plate 14 is movably installed on the bottom of the mounting cover 15.

[0027] The second cylinder 13 is installed and activated. The extension end of the second cylinder 13 extends, causing the mounting cover 15 to descend, which in turn causes the grinding plate 14 to descend, so as to facilitate the grinding of the pin.

[0028] Furthermore, a threaded rod 16 is rotatably installed inside the mounting cover 15, and a motor 17 for driving the threaded rod 16 to rotate is fixedly installed on the side wall of the mounting cover 15. A threaded block 18 is screwed onto the threaded rod 16, and the grinding plate 14 is fixedly connected to the threaded block 18.

[0029] The motor 17 is installed and started to drive the threaded rod 16 to rotate. The rotation of the threaded rod 16 can drive the threaded block 18 to move, thereby driving the grinding plate 14 to move, so as to grind the pin.

[0030] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0031] The working principle and usage process of this utility model are as follows: In use, open the door on the front side wall of the housing 2, place the pin between the two pairs of clamping plates 10, and activate the first cylinder 5. The telescopic end of the first cylinder 5 extends, causing the fixed seat 11 to rise, and simultaneously causing the lifting block 8 to rise. During the rise of the lifting block 8, the hinge plate 9 can swing. Through the cooperation between the rotating roller 12 and the clamping plates 10, the pin can be clamped and fixed. At this time, activate the second cylinder 13. The telescopic end of the second cylinder 13 extends, causing the mounting cover 15 and the grinding plate 14 to descend until the grinding plate 14 contacts the pin. The motor 17 on the mounting cover 15 is started to drive the threaded rod 16 to rotate, thereby driving the threaded block 18 to move, which in turn drives the grinding plate 14 to move and grind the pin. When it is necessary to rotate the pin, the first cylinder 5 is started again. The telescopic end of the first cylinder 5 retracts, causing the fixed seat 11 to descend. The pin descends with the fixed seat 11. At this time, the clamping plates 10 on both sides no longer clamp the pin. The motor 17 on the fixed plate is started to drive the rotating roller 12 to rotate, thereby driving the pin to rotate. After rotating to the surface to be ground, the motor 17 is turned off, and the first cylinder 5 is started again to clamp and fix the pin for grinding.

[0032] 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.
