Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of screw processing equipment, specifically a grinding machine for screw processing. Background Technology
[0002] A screw is a tool that uses the inclined plane of an object to rotate and friction to fasten objects and machine parts. It is an indispensable industrial necessity in daily life. Common screw materials include carbon steel, stainless steel, and copper. Carbon steel screws have high strength but poor corrosion resistance; stainless steel screws have strong corrosion resistance but relatively low strength; copper screws have good electrical conductivity and corrosion resistance, but are more expensive.
[0003] When processing screws, in order to ensure the quality of the screws, it is necessary to use a corresponding grinding machine to grind the tail of the screw to remove burrs and prevent scratches to the user. However, existing grinding machines still have shortcomings in actual use. Since most of their grinding discs are fixed in the vertical direction, they can only grind the end face of the screw tail and cannot adjust the angle of the grinding disc. As a result, the edge of the screw tail cannot be effectively ground. Therefore, this needs to be improved. Utility Model Content

[0006] As a preferred embodiment of this utility model, a lifting block is movably sleeved at the bottom of the interior of the movable frame, and an internal toothed plate is fixedly installed at the middle of the top of the lifting block. The top of the internal toothed plate penetrates the movable frame and extends to the outside of the movable frame.
[0007] As a preferred embodiment of this utility model, a second motor is fixedly installed at the top of the middle right end of the movable frame, and a rotating shaft is fixedly sleeved at the other end of the output shaft of the second motor. A gear is fixedly sleeved on the left side of the outer surface of the rotating shaft, and the outer surface of the gear meshes with the inner wall of the rear side of the internal tooth plate.
[0008] As a preferred embodiment of this utility model, a power motor is fixedly installed in the middle of the right end of the lifting block, and a power shaft is fixedly sleeved on the other end of the output shaft of the power motor. The left end of the power shaft passes through the lifting block and extends to the left side of the lifting block.
[0009] As a preferred embodiment of this utility model, a placement plate is fixedly installed on the left end of the power shaft, the right end of the placement plate is movably connected to the left end of the lifting block, and concave clamps are movably sleeved on the front and rear sides inside the placement plate.
[0010] As a preferred embodiment of this utility model, there are two concave clamps, and each of the two concave clamps is threaded with a double-threaded rod. The front and rear ends of the double-threaded rods pass through the placement plate and extend to the outside of the placement plate, and are fixedly sleeved with handles. The outer surface of the handles is movably connected to the outer surface of the placement plate.
[0011] As a preferred embodiment of this utility model, a drive motor is fixedly installed in the middle of the right end of the workbench, and a drive shaft is fixedly sleeved on the other end of the output shaft of the drive motor. The left end of the drive shaft passes through the workbench and extends to the left side of the workbench.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, by setting up a round shaft, a rotating plate, a round rod, a push plate, and a lead screw, will cause the lead screw to rotate when the first motor is started. Since the outer surface of the lead screw and the inner surface of the bottom end of the push plate are threaded together, the push plate will move with the round rod as the lead screw rotates, thereby causing the rotating plate to rotate around the round shaft under the drive of the round rod. This will cause the connecting rod and the grinding disc to rotate together with the rotating plate, thus enabling the adjustment of the grinding angle of the grinding disc by means of the round shaft, rotating plate, round rod, and push plate.
[0014] 2. This utility model, by setting up a lifting block, an internal toothed plate, a second motor, a rotating shaft, and a gear, will cause the rotating shaft to drive the gear to rotate when the second motor is started. Since the outer surface of the gear is meshed with the inner wall of the rear side of the internal toothed plate, the internal toothed plate will move along the inner surface of the moving frame with the lifting block under the action of the gear. In this way, the screw height can be adjusted by the cooperation of the internal toothed plate and the gear, thereby preventing the screw from failing to contact the grinding disc for grinding after the grinding disc is adjusted.

[0021] 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.
[0022] like Figures 1 to 5As shown, this utility model provides a screw grinding machine, including a worktable 1. A movable frame 2 is movably installed on the right side of the top center of the worktable 1. A fixed block 3 is fixedly installed on the left side of the top center of the worktable 1. A round shaft 4 is fixedly sleeved on the top right end of the fixed block 3. A rotating plate 5 is movably sleeved on the middle of the outer surface of the round shaft 4. The outer surface of the rotating plate 5 and the inner surface of the fixed block 3 are movably sleeved. A connecting rod 6 is fixedly sleeved on the inside of the top of the rotating plate 5. A grinding disc 7 is fixedly installed on the right end of the connecting rod 6. The bottom end of the rotating plate 5 is... A round rod 8 is fixedly sleeved at the bottom of the surface. A push plate 9 is movably sleeved on the outer surface of the round rod 8. The outer surface of the push plate 9 is movably sleeved on the inner surface of the bottom end of the rotating plate 5. The bottom of the outer surface of the push plate 9 is movably sleeved on the bottom end of the fixed block 3. A first motor 10 is fixedly installed in the middle of the left end of the fixed block 3. A lead screw 11 is fixedly sleeved on the other end of the output shaft of the first motor 10. The right end of the lead screw 11 passes through the fixed block 3 and extends to the right side of the fixed block 3. The right side of the outer surface of the lead screw 11 is threadedly sleeved on the inner surface of the bottom end of the push plate 9.
[0023] When the first motor 10 starts, the lead screw 11 will rotate. Since the lead screw 11 and the push plate 9 are threaded together, the push plate 9 will move under the action of the lead screw 11. Since the inner surface of the push plate 9 and the outer surface of the round rod 8 are movably connected and the round rod 8 and the rotating plate 5 are fixedly connected, the round rod 8 will move along with the bottom end of the rotating plate 5 and the push plate 9. This will cause the rotating plate 5 to rotate around the round shaft 4, carrying the connecting rod 6 and the grinding disc 7. This will allow the grinding angle of the grinding disc 7 to be adjusted.
[0024] The bottom of the movable frame 2 is movably sleeved with a lifting block 12, and an internal toothed plate 13 is fixedly installed at the middle of the top of the lifting block 12. The top of the internal toothed plate 13 passes through the movable frame 2 and extends to the outside of the movable frame 2.
[0025] When the internal tooth plate 13 moves along the inner surface of the top of the movable frame 2, it will move along with the lifting block 12.
[0026] The second motor 14 is fixedly installed at the top of the middle right side of the mobile frame 2. The other end of the output shaft of the second motor 14 is fixedly sleeved with a rotating shaft 15. A gear 16 is fixedly sleeved on the left side of the outer surface of the rotating shaft 15. The outer surface of the gear 16 is meshed with the inner wall of the rear side of the internal tooth plate 13.
[0027] When the second motor 14 is started, the rotating shaft 15 will drive the gear 16 to rotate, thereby causing the internal tooth plate 13, which is meshed with the gear 16, to move along the inner surface of the moving frame 2 along with the lifting block 12.
[0028] Among them, a power motor 17 is fixedly installed in the middle of the right end of the lifting block 12, and a power shaft 18 is fixedly sleeved on the other end of the output shaft of the power motor 17. The left end of the power shaft 18 passes through the lifting block 12 and extends to the left side of the lifting block 12.
[0029] When the power motor 17 is started, the power shaft 18 will rotate along the inner surface of the lifting block 12, and the power motor 17 will also move along with the lifting block 12.
[0030] The left end of the power shaft 18 is fixedly installed with a placement plate 19, the right end of the placement plate 19 is movably connected to the left end of the lifting block 12, and the front and rear sides of the placement plate 19 are respectively movably fitted with concave clamps 20.
[0031] When the drive shaft 18 rotates, the placement plate 19, which is fixedly connected to the drive shaft 18, will rotate along with it, and the concave clamp 20 is used to clamp the fixing screw.
[0032] Among them, there are two concave clamps 20, and the interior of the two concave clamps 20 are respectively threaded with double threaded rods 21. The front and rear ends of the double threaded rods 21 pass through the placement plate 19 and extend to the outside of the placement plate 19 and are fixedly sleeved with handles 22. The outer surface of the handles 22 is movably connected to the outer surface of the placement plate 19.
[0033] When the handle 22 is turned, the double threaded rod 21 will rotate, causing the two concave clamps 20 that are threadedly connected to the double threaded rod 21 to move in opposite directions and clamp the fixing screw.
[0034] A drive motor 23 is fixedly installed in the middle of the right end of the worktable 1. A drive shaft 24 is fixedly sleeved on the other end of the output shaft of the drive motor 23. The left end of the drive shaft 24 passes through the worktable 1 and extends to the left side of the worktable 1. A limit block 25 is threaded on the right side of the outer surface of the drive shaft 24. The outer surface of the limit block 25 is movably sleeved with the inner surface of the worktable 1. The top end of the limit block 25 is fixedly connected with the bottom end of the moving frame 2.
[0035] When the drive motor 23 starts, the drive shaft 24 will rotate, causing the limit block 25, which is threadedly connected to the drive shaft 24, to move the moving frame 2 toward the fixed block 3.
[0036] Working principle and usage process of this utility model:
[0037] In use, the operator first places the screw between the two concave clamps 20, then turns the handle 22 to rotate the double threaded rod 21, causing the two concave clamps 20, which are threadedly connected to the double threaded rod 21, to move towards each other and clamp the screw. Next, the operator starts the first motor 10, causing the lead screw 11 to rotate, which causes the push plate 9, which is threadedly connected to the outer surface of the lead screw 11, to move along the bottom end inside the fixed block 3. Since the round rod 8 and the push plate 9 are movably connected, the round rod 8 will move along with the bottom end of the rotating plate 5, causing the rotating plate 5 to rotate around the round shaft 4, carrying the connecting rod 6 and the grinding disc 7, until the grinding disc 7 rotates to the required angle, thereby adjusting the grinding angle of the grinding disc 7.
[0038] The operator then starts the second motor 14, causing the rotating shaft 15 to drive the gear 16 to rotate. This causes the internal tooth plate 13, which meshes with the gear 16, to move upward along with the lifting block 12 until the screw fixed by the concave clamp 20 aligns with the grinding disc 7. Next, the operator starts the power motor 17, causing the power shaft 18 to rotate along with the screw via the placement disc 19. Then, the operator starts the drive motor 23, causing the drive shaft 24 to rotate. This causes the limiting block 25, which is threaded onto the drive shaft 24, to move along with the screw towards the grinding disc 7 via the moving frame 2 until the screw contacts the grinding disc 7 and the grinding operation is completed as the screw rotates.
