Description

Technical Field

[0001] The invention relates to the technical field of hardware production, in particular to a grinding device for producing hardware products. Background Art

[0002] The existing hardware metal pipe grinding mainly uses a grinding belt to grind the end face and outer circle of the hardware metal pipe manually, which has high labor intensity and low grinding efficiency. In order to reduce the manual grinding intensity, the existing hardware metal pipe grinding device usually limits the hardware metal pipe by a limit clamp during grinding to ensure that the hardware metal pipe does not slide, and then grinds the end face and outer circle of the hardware metal pipe in turn by the grinding belt. However, when grinding with this hardware metal pipe grinding device, it is first necessary to manually place the hardware metal pipe, and then fix the hardware metal pipe to ensure that the hardware metal pipe does not slide, and then it is necessary to manually guide the grinding belt to approach the hardware metal pipe to make the grinding belt and the hardware metal pipe friction, so as to grind the hardware metal pipe. When grinding multiple hardware metal pipes, it is necessary to manually repeat this process, resulting in the inability to improve the efficiency of the hardware metal pipe, thereby reducing the productivity and benefits of the enterprise. Summary of the invention

[0003] The purpose of the present invention is to provide a grinding device for hardware product production to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, a grinding device for hardware product production is provided, including a base structure, a shaft rod structure is arranged above the base structure, a metal tube is sleeved on the shaft rod structure, and an abrasive belt is arranged below the metal tube.

When the shaft rod structure and the base structure squeeze each other inside the metal tube, the base structure pushes the shaft rod structure to expand inside the metal tube, so that the shaft rod structure squeezes and fixes the inner wall of the metal tube; the base structure rotates to drive the shaft rod structure to rotate. When the shaft rod structure expands inside the metal tube, the base structure drives the shaft rod structure and the metal tube to rotate, and the abrasive belt grinds the rotating metal tube.

[0007] As a further improvement of the present technical solution, a connecting sleeve is sleeved on the rotating rod, and a plurality of spline teeth are installed on the side of the rotating rod. The rotation of the rotating rod drives the connecting sleeve to rotate through the spline teeth. A plurality of connecting double rods are hinged on the side of the connecting sleeve. An arc plate is hinged on the end of the connecting double rod away from the connecting sleeve. A plurality of arc plates are arranged in a circular array around the connecting sleeve. The metal tube sleeve is arranged on a plurality of arc plates. The arc plate swings on the side of the connecting sleeve through the connecting double rod. When the arc plate is parallel to the connecting sleeve and the connecting double rod is perpendicular to the connecting sleeve, the arc plate squeezes the inner wall of the metal tube to fix the metal tube.

[0009] As a further improvement of the technical solution, a sliding sleeve on the rotating rod is provided with a gear rod, which is arranged between the second bevel gear and the connecting sleeve and fixedly connected to the connecting sleeve.

[0025] Example 1

[0026] See also Figure 1-Figure 7 As shown, the purpose of this embodiment is to provide a grinding device for hardware product production, including a base structure 1, a shaft structure 2 is arranged above the base structure 1, a metal tube is sleeved on the shaft structure 2, and an abrasive belt is arranged below the metal tube. The shaft structure 2 is driven to rotate by the base structure 1, and the metal tube is rotated so that the metal surface can be quickly processed in a high-speed rotating manner during grinding, which greatly shortens the processing time and improves the production efficiency. At the same time, the shaft structure 2 is driven by the base structure 1 to slide above the base structure 1, so that the shaft structure 2 slides to the metal tube. The shaft structure 2 is arranged inside the metal tube, thereby improving the positioning speed of the metal tube and further improving the production efficiency. When the shaft structure 2 is unfolded inside the metal tube, the base structure 1 drives the shaft structure 2 and the metal tube to rotate. The shaft structure 2 and the base structure 1 squeeze each other inside the metal tube so that the shaft structure 2 is unfolded inside the metal tube. The unfolded shaft structure 2 squeezes the inner side wall of the metal tube and fixes the metal tube. When the shaft structure 2 rotates, it drives the metal tube to rotate, so that the shaft structure 2 drives the metal tube to rotate after fixing the metal tube, and the rotating metal tube is polished by the sanding belt.

[0027] The base structure 1 includes a base plate 11, a polishing disc 13 is fixedly installed on one side of the base plate 11, and a sanding belt is fixedly installed on the upper side of the polishing disc 13. By placing a metal pipe above the polishing disc 13, friction is generated between the metal pipe and the sanding belt when the metal pipe rotates, and the rough sanding belt grinds off the burrs or rust on the surface of the metal pipe, thereby achieving rapid grinding of the metal pipe.

[0028] A motor 12 is fixedly installed above the base plate 11, and the rotating shaft of the motor 12 provides power for rotation and sliding, so as to fix the metal tube and drive the metal tube to rotate. The side of the motor 12 close to the polishing plate 13 is connected to the first gear 15 through the rotating shaft, and the side of the first gear 15 close to the polishing plate 13 is fixedly connected to the first bevel gear. When the rotating shaft of the motor 12 rotates, it drives the first bevel gear to rotate. An intermediate bevel gear 16 is meshed below the first gear 15, and the power is transmitted to the intermediate bevel gear 16 through the meshing between the gears. A second bevel gear 22 is meshed on one side of the intermediate bevel gear 16, and a rotating rod 21 is fixedly connected to the side of the second bevel gear 22 away from the intermediate bevel gear 16. The rotating shaft of the motor 12 drives the first gear 15 to rotate, and the rotation of the first gear 15 drives the intermediate bevel gear 16 to rotate through the first bevel gear, and the rotation of the intermediate bevel gear 16 drives the rotating rod 21 to rotate through the second bevel gear 22.

[0029] A connecting sleeve 24 is sleeved on the rotating rod 21, and a plurality of spline teeth 211 are installed on the side of the rotating rod 21. The spline teeth 211 can realize axial sliding while the rotating rod 21 transmits torque. The rotating rod 21 rotates and drives the connecting sleeve 24 to rotate through the spline teeth 211. When the rotating rod 21 rotates, the inclined surface on the spline teeth 211 will apply a lateral force to the rotating rod 21. This force enables the rotating rod 21 to transmit force to the spline teeth 211. As the rotating rod 21 continues to rotate, the spline teeth 211 are affected by this lateral force and move along the axial direction of the rotating rod 21. A plurality of connecting double rods 25 are hinged on the side of the connecting sleeve 24. An arc plate 26 is hinged on one end of the connecting double rod 25 away from the connecting sleeve 24. A plurality of arc plates 26 are arranged in a circular array around the connecting sleeve 24, and a metal pipe sleeve is arranged on the plurality of arc plates 26. 6, the metal tube is fixed by the friction between the arc plate 26 and the inner wall of the metal tube, so as to avoid slipping when the arc plate 26 drives the metal tube to rotate, which affects the grinding effect and causes production accidents. The arc plate 26 swings on the side of the connecting sleeve 24 through the connecting double rods 25. When the arc plate 26 is parallel to the connecting sleeve 24 and the connecting double rods 25 are perpendicular to the connecting sleeve 24, the arc plate 26 squeezes the inner wall of the metal tube to fix the metal tube. When the arc plate 26, the connecting double rods 25 and the connecting sleeve 24 are all parallel, several arc plates 26 are folded on the surface of the connecting sleeve 24. At this time, the metal tube is placed on the polishing disc 13, and slides into the inside of the metal tube through the connecting sleeve 24 to quickly position the metal tube, eliminating the process of manual metal tube positioning, thereby improving the efficiency of grinding the metal tube.

[0030] A connecting rod 17 is provided on one side of the first gear 15. A second gear 171 is fixedly sleeved on one end of the connecting rod 17 and meshed with the first gear 15 through the second gear 171. When the rotating shaft of the motor 12 rotates, the first gear 15 is driven to rotate, and the second gear 171 is driven to rotate through the first gear 15, thereby driving the connecting rod 17 to rotate. A worm 172 is fixedly sleeved on one end of the connecting rod 17 away from the first gear 15, and a worm wheel 18 is meshed on one side of the worm 172. The worm wheel 18 is arranged between the rotating rod 21 and the connecting rod 17. The rotation of the rotating shaft of the motor 12 drives the second gear 171 to rotate through the first gear 15. The rotation of the second gear 171 drives the worm wheel 18 to rotate through the worm 172. The connecting sleeve 24 is pushed to slide into the inside of the metal pipe through the worm wheel 18, and then the metal pipe is fixed through the expanded arc plate 26, so that the equipment can quickly position the metal pipe when grinding it, and drive the metal pipe to rotate, thereby effectively improving the processing efficiency of the metal pipe.

[0031] A top cylinder 14 is provided at one end of the connecting sleeve 24 away from the motor 12. When the connecting sleeve 24 slides inside the metal tube, the top cylinder 14 is squeezed, and the connecting double rod 25 is pushed by the top cylinder 14 to unfold the arc plate 26 from the inside of the metal tube. A pin hole is provided at one end of the top cylinder 14 close to the motor 12, and the connecting sleeve 24 is inserted into the pin hole. The worm gear 18 rotates to push the gear rod 23, so that the gear rod 23 drives the connecting sleeve 24 to slide into the pin hole inserted into the top cylinder 14, and the connecting double rod 25 is pushed by the end of the top cylinder 14 to swing close to the connecting sleeve 24. The arc plate 26 is unfolded inside the metal tube and squeezes the inner wall of the metal tube through the connecting double rod 25, thereby fixing the metal tube from the inside of the metal tube.

[0032] The present invention drives the first gear 15 to rotate through the rotating shaft of the motor 12, and transmits power to the rotating rod 21 through the second bevel gear 22 through the meshing of the intermediate bevel gear 16 and the first bevel gear, and drives the connecting sleeve 24 to rotate through the rotating rod 21, and then drives the metal pipe to rotate on the polishing disc 13 through the arc plate 26. Through the continuous friction between the sand belt on the polishing disc 13 and the rotating metal pipe, the device can quickly grind the rust or burrs on the surface of the metal pipe, effectively improving the grinding efficiency of the metal pipe. At the same time, through the meshing between the second gear 171 and the first gear 15, the rotating shaft of the motor 12 can drive the second gear 171 through the first gear 15 when rotating. The gear 171 rotates, and then drives the worm 172 and the worm wheel 18 to rotate through the connecting rod 17, and pushes the gear rod 23 to slide through the worm wheel 18, so that the connecting sleeve 24 slides to the inside of the metal tube placed on the polishing disk 13, until the connecting sleeve 24 is inserted into the pin hole of the top cylinder 14. At this time, the end of the top cylinder 14 squeezes the connecting double rod 25, so that the connecting double rod 25 swings inside the metal tube, and drives the arc plate 26 to approach the inner wall of the metal tube, and then squeezes the inner wall of the metal tube through a plurality of arc plates 26 so that the connecting sleeve 24 can firmly fix the metal tube when rotating, and at the same time, it also improves the positioning speed of the metal tube, further improving the production efficiency.
