Technical Field
[0001] This utility model belongs to the field of pin shaft processing technology, specifically a grinding device for processing pin shaft parts. Background Technology
[0002] A pin is typically a cylindrical part, and pin machining is a manufacturing process used to produce various types of pins or pin parts. These parts are commonly used in mechanical devices that connect, fix, or transmit force and motion, primarily at the hinge points of two parts, serving to connect and transmit torque. Sometimes they are also used as locating pins. During the machining process, pins need to be ground to ensure the flatness of their surface. Existing grinding equipment typically involves manually moving the grinding wheel to contact the pin for grinding. However, during the grinding process, the pin may loosen, leading to missed areas and affecting the overall grinding quality. Utility Model Content
[0003] To overcome the above-mentioned defects, this utility model provides a grinding device for processing pin shaft parts. It solves the problem that when using the grinding device, the grinding wheel is usually moved manually to contact the pin shaft for grinding. However, during the grinding process, the pin shaft becomes loose, resulting in omissions in the grinding of the pin shaft and affecting the grinding quality of the pin shaft.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for processing pin shaft parts, comprising a base, an installation frame fixedly connected to the top of the base, a support frame fixedly connected to the top of the installation frame, an electric telescopic rod installed at the middle position of the top of the support frame, a lifting plate installed at the bottom of the electric telescopic rod passing through the support frame, four connecting rods slidably connected through the four corners of the bottom of the lifting plate, mounting blocks fixedly connected at the bottom of the connecting rods passing through the lifting plate, a spring sleeved on the surface of the connecting rod between the lifting plate and the mounting block, a connecting block fixedly connected between two mounting blocks, a motor fixedly connected to one side of one of the connecting blocks, a grinding wheel provided on the output shaft of the motor, and the grinding wheel rotatably connected to the connecting block through a bearing.
[0005] As a further embodiment of this utility model: the top of the lifting plate is fixedly connected to limit rods on both sides of the electric telescopic rod, and the limit rods are slidably connected to the inner wall of the support frame.
[0006] As a further embodiment of this utility model: a collection box is slidably connected through one side of the base, and plug-in blocks are fixedly connected to both sides of the collection box, with the plug-in blocks slidably connected through the inner wall of the base.
[0007] As a further embodiment of this utility model: one side of the plug block passes through the base and is fixedly connected to a limiting post, and the two sides of the opening of the base are rotatably connected by pins, with the rotating plates corresponding to the positions of the limiting posts.
[0008] As a further embodiment of this utility model: two electric push rods are fixedly connected to both ends of the mounting frame, and a movable plate is installed on one side of each of the two electric push rods through the mounting frame.
[0009] As a further embodiment of this utility model: limiting blocks are fixedly connected to both sides of the movable plate, and two sliding grooves are symmetrically opened inside the mounting frame, with the sliding grooves being movably connected to the limiting blocks.
[0010] As a further embodiment of this utility model: two connecting seats are fixedly connected to the side of the movable plate away from the electric push rod, and two fixing rods are fixedly connected inside the connecting seats.
[0011] As a further embodiment of this utility model: a movable block is movably connected inside the connecting seat, the movable block is slidably connected to the fixed rod, a spring is sleeved on the surface of the fixed rod located on one side of the movable block, and a clamping wheel is rotatably connected between the two movable blocks through a bearing.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This grinding device for processing pin shaft parts comprises an electric telescopic rod, a spring, a motor, and a lifting plate. After the pin shaft is placed between the clamping wheels, the electric telescopic rod drives the lifting plate to move downwards. The lifting plate, through a connecting rod, drives the grinding wheel downwards, allowing the grinding wheel to contact the pin shaft. As the electric telescopic rod continues to push, the lifting plate compresses the spring, causing the spring to generate a relative elastic force that pushes the grinding wheel tightly against the pin shaft surface. This facilitates the motor-driven grinding wheel to grind and polish the pin shaft, ensuring the grinding effect of the device on the pin shaft.
[0013] 2. The grinding device for processing pin parts is equipped with an electric push rod, clamping wheels, a movable block, and a collection box. The electric push rod pushes two movable plates to move relative to each other, so that the movable plates drive the clamping wheels to move relative to each other through the connecting seat and the movable block until the two clamping wheels contact each other. This makes it convenient to place the pin between the two clamping wheels for grinding. After grinding is completed, the electric push rod drives the clamping wheels to disengage through the movable plate and the connecting seat, so that the pin falls into the collection box for easy collection of the ground pin.

[0015] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0016] like Figure 1-4 As shown, this utility model provides a technical solution: a grinding device for processing pin shaft parts, including a base 1, a collection box 13 is slidably connected through one side of the base 1, and plug blocks 14 are fixedly connected to both sides of the collection box 13. The plug blocks 14 are slidably connected through the inner wall of the base 1. By setting the collection box 13, the pin shaft falls into the collection box 13 after grinding, so that the collection box 13 can collect the pin shaft in a unified manner, thereby facilitating the subsequent removal of the pin shaft in the collection box 13. One side of the plug-in block 14 passes through the base 1 and is fixedly connected to the limiting post 15. The two sides of the opening of the base 1 are rotatably connected by the pivot pin. The pivot plate 16 is positioned corresponding to the limiting post 15. By setting the pivot plate 16, the pivot plate 16 overlaps with the limiting post 15, thereby limiting the collection box 13 and the plug-in block 14, making it easy to install the collection box 13 inside the base 1. The top of the base 1 is fixedly connected to the mounting frame 2. Two electric push rods 17 are fixedly connected to both ends of the mounting frame 2. A movable plate 18 is installed on one side of the two electric push rods 17 through the mounting frame 2. By setting the electric push rods 17, the electric push rods 17 push the movable plate 18 to move, so that the movable plate 18 can drive the clamping wheel 23 to move, thereby adjusting the position of the clamping wheel 23. Limiting blocks 19 are fixedly connected to both sides of the movable plate 18. Two sliding grooves 25 are symmetrically opened inside the mounting frame 2. The sliding grooves 25 are movably connected to the limiting blocks 19. By setting the limiting blocks 19, when the electric push rod 17 pushes the movable plate 18 to move, the movable plate 18 can drive the limiting blocks 19 to slide inside the sliding grooves 25, so that the sliding grooves 25 can limit the movable plate 18 through the limiting blocks 19, thereby allowing the movable plate 18 to drive the clamping wheel 23 to move more stably. Two connecting seats 20 are fixedly connected to the side of the movable plate 18 away from the electric push rod 17. Two fixed rods 21 are fixedly connected inside the connecting seats 20. By setting the fixed rods 21, the movable blocks 22 on both sides of the clamping wheel 23 slide on the surface of the fixed rods 21, so that the fixed rods 21 can limit the movement of the movable blocks 22, making the movement of the movable blocks 22 more stable. The connecting seat 20 is internally connected to a movable block 22, which is slidably connected to a fixed rod 21. A second spring 24 is sleeved on the surface of the fixed rod 21 on one side of the movable block 22. A clamping wheel 23 is rotatably connected between the two movable blocks 22 through a bearing. By setting the second spring 24, the movable blocks 22 on both sides of the clamping wheel 23 move and squeeze the second spring 24, so that the second spring 24 generates a relative elastic force. The elastic force of the second spring 24 drives the clamping wheel 23 to press tightly against the pin surface. A support frame 3 is fixedly connected to the top of the mounting frame 2. An electric telescopic rod 4 is installed in the middle of the top of the support frame 3. A lifting plate 5 is installed through the support frame 3 at the bottom of the electric telescopic rod 4. Limiting rods 12 are fixedly connected to the top of the lifting plate 5 on both sides of the electric telescopic rod 4. The limiting rods 12 are slidably connected to the inner wall of the support frame 3. By setting the limiting rods 12, the electric telescopic rod 4 drives the lifting plate 5 to move down. The lifting plate 5 drives the limiting rods 12 to slide inside the support frame 3. The support frame 3 can limit the movement of the lifting plate 5 through the limiting rods 12, so that the lifting plate 5 can stably drive the grinding wheel 11 to move up and down. Four connecting rods 6 are slidably connected through the four corners of the bottom of the lifting plate 5. The bottom of the connecting rods 6 passes through the lifting plate 5 and is fixedly connected to the mounting block 8. A spring 7 is sleeved on the surface of the connecting rod 6 between the lifting plate 5 and the mounting block 8. A connecting block 9 is fixedly connected between two mounting blocks 8. A motor 10 is fixedly connected to one side of one of the connecting blocks 9. A grinding wheel 11 is set on the output shaft of the motor 10. The grinding wheel 11 and the connecting block 9 are rotatably connected by a bearing. With the setting of the spring 7, after the grinding wheel 11 abuts against the pin surface, the electric telescopic rod 4 drives the lifting plate 5 to squeeze the spring 7, causing the spring 7 to deform and generate a relative elastic force to drive the grinding wheel 11 to press tightly against the pin surface, ensuring the grinding effect of the grinding wheel 11 on the pin.
[0017] The working principle of this utility model is as follows: Start the electric push rod 17, which moves the movable plate 18, allowing it to move the clamping wheels 23 relative to each other, bringing them into contact. As the electric push rod 17 continues to push, the movable blocks 22 on both sides of the clamping wheels 23 compress the springs 24. Then, place the pin between the two clamping wheels 23. Start the electric telescopic rod 4, which moves the lifting plate 5 downward, causing it to move the grinding wheel 11 downward via the connecting rod 6. This allows the grinding wheel 11 to press against the pin surface. As the electric telescopic rod 4 moves the lifting plate 5 downward, the grinding wheel 11 presses against the pin surface. The lowering plate 5 moves, and the lifting plate 5 squeezes the spring 7, causing the spring 7 to deform and squeeze the mounting block 8. This causes the mounting block 8 to drive the grinding wheel 11 to press tightly against the pin surface. The motor 10 is started, and the motor 10 drives the grinding wheel 11 to rotate through the output shaft, so that the grinding wheel 11 grinds the pin. After the grinding of the pin is completed, the electric push rod 17 drives the movable plate 18 to move, so that the movable plate 18 drives the clamping wheel 23 to disengage, allowing the pin between the clamping wheels 23 to fall into the collection box 13, so that the collection box 13 can collect the pin.
