Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to a high-efficiency nut end face grinding component. Background Technology

[0002] Nuts, also known as bolts, are parts that are screwed together with bolts or screws to provide a fastening function. They are an essential component in manufacturing machinery. During the production process, nut end face grinders are used to grind the end face of the nut to remove burrs, unevenness, or dirt to achieve the required surface quality.

[0003] Existing nut end face grinding machines typically only have fixtures that can grind one type of nut. Grinding different types of nuts requires changing the fixture, resulting in limited applicability and low work efficiency. Therefore, we propose a high-efficiency nut end face grinding component. Utility Model Content

[0004] To solve the above technical problems, this application provides a high-efficiency nut end face grinding component, including a support table, a grinding machine, and a cylinder. A pushing component is fixedly connected to the end of the cylinder, and a telescopic rod is fixedly connected to the upper end of the cylinder. A positioning frame is fixedly connected to the rear end of the telescopic rod. A moving component is provided inside the positioning frame, and a fixed plate is fixedly connected to the upper end of the moving component. A turntable is rotatably connected to the inner cavity of the fixed plate. The turntable is provided with a rotating component that controls the rotation of the turntable. Several sliding grooves are penetrating the outer side of the turntable and arranged along the circumference of the turntable. A clamping component for fixing the nut hole is provided in the sliding groove, and a sliding component for controlling the rotation of the clamping component is provided inside the turntable.

[0005] Preferably, the pushing member includes a pushing block fixedly connected to the front end of the cylinder, and a first magnet is fixedly connected to the upper surface of the end of the pushing block furthest from the cylinder.

[0006] Preferably, the movable component includes a cylinder that is fixedly connected to both the upper and lower ends of the positioning frame. The cylinder has several arc-shaped grooves. A movable column is slidably connected inside the cylinder. Several cylinders are fixedly connected to the outside of the movable column, and the cylinders are slidably engaged within the arc-shaped grooves.

[0007] Preferably, the rotating component includes a rotating handle fixedly connected to the outer side of the turntable, a rotating groove is provided on the outer side of the fixed disk, the rotating handle is slidably fitted in the rotating groove, and a limit clamp is movably connected to the lower end of the rotating handle.

[0008] Preferably, the clamping member includes a movable plate that slides within the sliding groove, and a clamping post is fixedly connected to the end of the movable plate.

[0009] Preferably, the sliding member includes a positioning post rotatably connected to one end of the movable plate near the outer side of the fixed plate, a rectangular frame is slidably connected to the outer side of the movable plate, and rotating posts are rotatably connected between the upper and lower surfaces of the sliding groove and the upper and lower surfaces of the rectangular frame.

[0010] Preferably, a second magnet is fixedly connected to both the upper and lower surfaces of the rotating handle.

[0011] This utility model has at least the following beneficial effects:

[0012] This invention involves inserting the nut hole into the clamping column, then rotating the rotating handle to rotate the turntable while simultaneously squeezing the limiting clamp, causing the moving plate within the rectangular frame to move synchronously until the clamping column abuts against the wall of the nut hole. The limiting clamp is then released, clamping the bottom surface of the fixed plate. The cylinder is then activated, pushing the push block to move the moving column towards the grinder until the telescopic rod extends to its maximum distance. The cylinder push rod continues to move towards the grinder until the push block and moving column no longer contact each other. Finally, the grinder is activated to grind the end face of the nut. After grinding, the cylinder push rod moves forward, causing the front end of the push block to push the moving column upward. The cylinder rotates along the arc groove, causing the nut to rotate to the other side. Then, the cylinder push rod moves backward, causing the push block to leave the moving column. The grinder then grinds the end face of the nut. This process is repeated until each side of the nut has been ground. Then, the cylinder push rod moves forward, causing the first magnet to attract the lower surface of the moving column and leave the grinder. After the nut is loosened, another nut can be replaced. This allows for grinding of different nut models, saving time and effort. Attached Figure Description

[0023] 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.

[0024] Example 1: Please refer to Figure 1-8 This utility model provides a technical solution: a high-efficiency nut end face grinding part, including a support table 1, a grinding machine 2 and a cylinder 3. A pushing part 4 is fixedly connected to the end of the cylinder 3, a telescopic rod 5 is fixedly connected to the upper end of the cylinder 3, a positioning frame 6 is fixedly connected to the rear end of the telescopic rod 5, a moving part 7 is provided in the positioning frame 6, a fixed plate 8 is fixedly connected to the upper end of the moving part 7, a turntable 9 is rotatably connected to the inner cavity of the fixed plate 8, a rotating part 10 for controlling the rotation of the turntable 9 is provided on the turntable 9, several sliding grooves 11 are penetrating the outer side of the turntable 9 and arranged along the circumference of the turntable 9, a clamping part 12 for fixing the nut hole is provided in the sliding groove 11, and a sliding part 13 for controlling the rotation of the clamping part 12 is provided in the turntable 9;

[0025] In actual use, initially, the first magnet 402 attracts the lower end of the moving column 703. First, the hole of the nut is placed into the clamping column 1202. Then, the rotating handle 1002 is rotated to drive the turntable 9 to rotate, while the limiting clamp 1003 is pinched, causing the moving plate 1201 in the rectangular frame 1302 to move outward synchronously until the clamping column 1202 abuts against the wall of the nut hole. Then, the limiting clamp 1003 is released, clamping the bottom surface of the fixed plate 8. Then, the cylinder 3 is activated, pushing the push block 401 towards the grinder 2, thereby driving the moving column 703 to move until the telescopic rod 5 extends to its maximum distance between the grinder 2 and the machine. The push rod of the cylinder 3 continues to move towards the grinder 2. Move the cylinder 3 until the push block 401 no longer contacts the moving column 703. Then, start the grinder 2 to grind the end face of the nut. After grinding, the push rod of the cylinder 3 moves forward, causing the front end of the push block 401 to push the moving column 703 upward. The cylinder 704 will rotate 60 degrees along the trajectory of the arc groove 702, causing the nut to rotate to the other side. Then, the push rod of the cylinder 3 moves backward, pushing the push block 401 away from the moving column 703. Then, the grinder 2 grinds the end face of the nut. Repeat this process until each side of the nut has been ground. Then, the push rod of the cylinder 3 moves forward, causing the first magnet 402 to attract the lower surface of the moving column 703 and leave the grinder 2. After loosening the nut, replace it with another nut.

[0026] Furthermore, the pusher 4 includes a pusher block 401 fixedly connected to the front end of the cylinder 3. A first magnet 402 is fixedly connected to the upper surface of the pusher block 401 at the end furthest from the cylinder 3. The first magnet 402 attracts the moving column 703, so that the push rod of the cylinder 3 can drive the moving column 703 away from the grinder 2, thereby facilitating the replacement of the nut.

[0027] Furthermore, the movable component 7 includes a cylinder 701 fixedly connected to both the upper and lower ends of the positioning frame 6. The cylinder 701 has several arc-shaped grooves 702. A movable column 703 is slidably connected inside the cylinder 701. Several cylinders 704 are fixedly connected to the outside of the movable column 703. The cylinders 704 are slidably fitted inside the arc-shaped grooves 702. There are 6 arc-shaped grooves 702, which are arranged along the circumference of the cylinder 701. By moving the movable column 703 up and down, the cylinders 704 are driven to move along the trajectory of the arc-shaped grooves 702, causing the movable column 703 to rotate. This allows the end face of the nut to be changed. The movable column 703 will move downward under the gravity of the upper end, making it less likely to move upward during the grinding of the nut.

[0028] Furthermore, the rotating component 10 includes a rotating handle 1002 fixedly connected to the outer side of the turntable 9. A rotating groove 1001 is provided on the outer side of the fixed disk 8. The rotating handle 1002 is slidably engaged in the rotating groove 1001. The lower end of the rotating handle 1002 is movably connected to a limiting clamp 1003. By rotating the rotating handle 1002, the turntable 9 is driven to rotate. At the same time, the limiting clamp 1003 is pinched, so that the movable plate 1201 in the rectangular frame 1302 moves outward synchronously until the clamping post 1202 abuts against the nut hole wall, thereby fixing different nuts.

[0029] Furthermore, the clamping member 12 includes a movable plate 1201 that slides within the sliding groove 11. A clamping post 1202 is fixedly connected to the end of the movable plate 1201. The clamping post 1202 contacts the hole wall of the nut to fix the nut.

[0030] Furthermore, the sliding member 13 includes a positioning post 1301 rotatably connected to one end of the movable plate 1201 near the outside of the fixed plate 8, a rectangular frame 1302 slidably connected to the outside of the movable plate 1201, and a rotating post 1303 rotatably connected between the upper and lower surfaces of the sliding groove 11 and the upper and lower surfaces of the rectangular frame 1302.

[0031] In summary: Initially, the first magnet 402 attracts the lower end of the moving column 703. First, the hole of the nut is placed into the clamping column 1202. Then, the rotating handle 1002 is rotated to drive the turntable 9 to rotate, while simultaneously pinching the limiting clamp 1003, thereby causing the position of the rectangular frame 1302 to change. This causes the moving plate 1201 inside the rectangular frame 1302 to move outward synchronously until the clamping column 1202 abuts against the wall of the nut hole. Then, the limiting clamp 1003 is released, clamping the bottom surface of the fixed plate 8. Then, the cylinder 3 is activated, pushing the push block 401 towards the grinder 2, thereby driving the moving column 703 to move until the telescopic rod 5 extends to its maximum distance between the grinder 2 and the moving column 703. After this, the push rod of the cylinder 3 continues to move towards the grinder 2 until the push block 401 and the moving column 703 are aligned. Without contacting column 703, the grinder 2 is started to grind the end face of the nut. After grinding, the push rod of cylinder 3 moves forward, causing the front end of the push block 401 to push the moving column 703 upward. The cylinder 704 will rotate 60 degrees along the trajectory of the arc groove 702, causing the nut to rotate to the other side. Then the push rod of cylinder 3 moves backward, causing the push block 401 to leave the moving column 703. Then the grinder 2 grinds the end face of the nut. This process is repeated until each side of the nut has been ground. Then the push rod of cylinder 3 moves forward, causing the first magnet 402 to attract the lower surface of the moving column 703 and leave the grinder 2. After the nut is loosened, another nut is replaced, and the grinding continues in the same manner. Alternatively, the movement pattern of cylinder 3 can be designed so that only the nut needs to be replaced for grinding.

[0032] Example 2: Please refer to Figure 9Based on Embodiment 1, the present invention has a second magnet 1004 fixedly connected to both the upper and lower surfaces of the rotating handle 1002. After the clamping post 1202 is fixed with a nut, the rotating handle 1002 is fixed by adsorbing the surface of the rotating groove 1001 through the second magnet 1004, so that the clamping post 1202 remains in its current position.
