[0001] The utility model belongs to the technical field of bolt processing, and more specifically, particularly relates to a special grinding tool for the hexagonal socket in a bolt. Background Art

[0002] A socket head cap screw has a cylindrical head and a hexagonal socket inside. It is convenient for installation and disassembly, and can be countersunk during installation, that is, the entire nut sinks into the workpiece, which can keep the surface of the workpiece flat and beautiful. It is widely used in various mechanical fields. When processing the socket head cap screw, the hexagonal socket needs to be ground.

[0003] Based on the above, the inventor found the following problems: For the existing special grinding tool for the hexagonal socket in a bolt, the cleaning effect of the residual iron filings in the hexagonal socket after grinding is not good. In order to increase the corrosion resistance of the bolt, some bolts need to be electroplated after grinding. If the residual iron filings are not cleaned up before electroplating, it will pollute the plating solution. Since the aperture of the hexagonal socket in the bolt is small, it is inconvenient to rinse with a cleaning solution during grinding. Cleaning the bolts collectively will increase the production steps and reduce the production efficiency.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a special grinding tool for the hexagonal socket in a bolt is provided, in order to achieve the purpose of having more practical value. Summary of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a special grinding tool for the hexagonal socket in a bolt to solve the problem that the existing special grinding tool for the hexagonal socket in a bolt has a poor cleaning effect on the residual iron filings in the hexagonal socket after grinding.

[0006] The purpose and effect of the special grinding tool for the hexagonal socket in a bolt of the utility model are achieved by the following specific technical means:

[0007] A special grinding tool for the hexagonal socket in a bolt includes a workbench, an electric telescopic rod, a movable platform and a fixture. The upper end surface of the workbench is provided with an electric telescopic rod and a fixture. One end of the electric telescopic rod is connected to the movable platform. The upper end surface of the movable platform is provided with a motor box. The output end of the motor box is provided with a grinding tool. A groove is opened on the upper end surface of the workbench. An electromagnet adsorption plate is installed in the groove. Slide grooves II are opened on both sides of the movable platform. Sliders are arranged in the slide grooves II. A connecting rod is installed between the slider and the electromagnet adsorption plate. Through holes are opened at both ends of the connecting rod. The connecting rod is rotatably connected to the slider.

[0008] Furthermore, a rotating shaft is installed on the inner wall of the groove. Circular grooves for the rotating shaft to enter are opened on both sides of the electromagnet adsorption plate.

[0009] Furthermore, circular bosses are installed on both sides of the electromagnet adsorption plate, and the circular bosses are rotatably connected to the connecting rod.

[0010] Furthermore, a first chute is provided on the side of the workbench, a waste box is installed in the first chute, a handle is installed on one side of the waste box, and the first chute is located below the groove.

[0011] Furthermore, a limiting plate is installed inside the groove.

[0012] Furthermore, a micro power supply is installed on the upper end surface of the electromagnet adsorption plate.

[0013] Furthermore, the connecting rod is made of aluminum alloy.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] Through the combined use of the connecting rod, the electromagnet adsorption plate and the waste box, during the preparation for grinding, the electric telescopic rod pushes the movable platform towards the fixture. At this time, the electromagnet adsorption plate is in the groove and parallel to the groove. When the internal hexagonal hole of the bolt is ground, when the electric telescopic rod drives the movable platform away from the fixture, the slider slides to the edge of the second chute. When the movable platform continues to move, it will drive the connecting rod to move. The other end of the connecting rod is rotatably connected to the circular boss on the electromagnet adsorption plate, pulling the electromagnet adsorption plate to rotate along the rotating shaft in the groove until it is pulled up by the connecting rod and perpendicular to the groove. At this time, the micro power supply is started, and the electromagnet adsorption plate generates magnetic force to adsorb the iron filings in the internal hexagonal hole of the bolt. When grinding in the next cycle, the electromagnet will be pushed into the groove again and clamped by the limiting plate when it rotates to be parallel to the groove. At this time, the micro power supply is turned off, and the iron filings will fall into the waste box below the groove, so as to achieve the effect of cleaning the iron filings in the internal hexagonal hole of the bolt during the grinding process, and further achieve the purpose of improving work efficiency.

[0023] Embodiment:

[0024] As shown in the attached Figure 1 to the attached Figure 4 shown:

[0025] The present utility model provides a special grinding tool for the internal hexagonal hole of a bolt, including a workbench 1, an electric telescopic rod 2, a movable platform 3 and a fixture 5. The upper end surface of the workbench 1 is provided with an electric telescopic rod 2 and a fixture 5. One end of the electric telescopic rod 2 is connected to a movable platform 3. The electric telescopic rod 2 can drive the movable platform 3 to move, controlling the grinding tool 304 to enter and leave the internal hexagonal hole of the bolt. The upper end surface of the movable platform 3 is provided with a motor box 303. The output end of the motor box 303 is provided with a grinding tool 304. Starting the motor in the motor box 303, its output end can drive the grinding tool 304 to rotate, for grinding the internal hexagonal hole of the bolt. The upper end surface of the workbench 1 is provided with a groove 101. An electromagnet adsorption plate 4 is installed in the groove 101. The two sides of the movable platform 3 are provided with second chutes 302. A slide block 305 is arranged in the second chute 302. A connecting rod 301 is installed between the slide block 305 and the electromagnet adsorption plate 4. Through holes are provided at both ends of the connecting rod 301. The connecting rod 301 is rotatably connected to the slide block 305. Through the connecting rod 301, when the movable platform 3 moves, it can drive the electromagnet adsorption plate 4 to rotate, adsorbing the residual iron filings in the adsorption hole.

[0026] Wherein, a rotating shaft 103 is installed on the inner wall of the groove 101. Circular grooves 402 for the rotating shaft 103 to enter are provided on both sides of the electromagnet adsorption plate 4, which can make the electromagnet adsorption plate 4 rotate in the groove 101, facilitating the progress of the work process.

[0027] Among them, circular bosses 403 are installed on both sides of the telescopic electromagnet adsorption plate 4. The circular bosses 403 are rotatably connected to the connecting rod 301. After the grinding tool 304 finishes grinding, the movable platform 3 moves backward. When the slider 305 moves to the edge of the second chute 302, continuous movement will cause the slider 305 to drive the connecting rod 301 to move. The connecting rod 301 pulls the circular boss 403 to rotate, driving the electromagnet adsorption plate 4 to rotate along the rotating shaft 103 in the groove 101, pulling up the electromagnet adsorption plate 4 to perform the adsorption work.

[0028] Among them, a first chute 104 is provided on the side of the workbench 1. A waste box 105 is installed in the first chute 104. A handle is installed on one side of the waste box 105. The first chute 104 is located below the groove 101. When the electromagnet adsorption plate 4 is in a state parallel to the groove 101, the micro power supply 401 can be turned off, and the iron filings will fall into the waste box 105, facilitating the staff to pull out the waste box 105 through the handle for centralized cleaning.

[0029] Among them, a limiting plate 102 is installed on the inner side of the groove 101 to limit the rotation angle of the electromagnet adsorption plate 4 and prevent the device from self-locking.

[0030] Among them, a micro power supply 401 is installed on the upper end surface of the electromagnet adsorption plate 4 to provide power for the electromagnet adsorption plate 4 to make it magnetic.

[0031] Among them, the connecting rod 301 is made of aluminum alloy, which is light in weight and convenient for the operation of the device.

[0032] The specific usage mode and function of this embodiment:

[0033] When carrying out the grinding work on the hexagonal socket of the bolt, first clamp the bolt in the fixture 5, with its head facing the grinding tool 304. Start the electric telescopic rod 2 to push the movable platform 3 towards the fixture 5. At this time, the electromagnet adsorption plate 4 is in the groove 101 and parallel to the groove 101. When the grinding tool 304 extends into the hexagonal socket of the bolt, the motor box 303 can be started to begin grinding. After the grinding of the hexagonal socket of the bolt is completed, the electric telescopic rod 2 drives the movable platform 3 away from the fixture 5, and the slider 305 will slide to the edge of the second chute 302. At this time, when the movable platform 3 continues to move, it will drive the connecting rod 301 to move. The other end of the connecting rod 301 is rotatably connected to the circular boss 403 on the electromagnet adsorption plate 4, pulling the electromagnet adsorption plate 4 to rotate along the rotating shaft 103 in the groove 101 until it is pulled up by the connecting rod 301 and perpendicular to the groove 101. At this time, start the micro power supply 401, and the electromagnet adsorption plate 4 generates magnetic force to adsorb the iron filings in the hexagonal socket of the bolt to complete the work. When the next cycle is carried out, when the movable platform 3 moves towards the fixture 5, it will push the electromagnet adsorption plate 4 into the groove 101 and be stuck by the limiting plate 102 when it rotates to be parallel to the groove 101. At this time, turn off the micro power supply 401, and the iron filings will fall into the waste box 105 below the groove 101. The staff needs to regularly clean the iron filings in the waste box 105. Through the above steps, the special grinding tool for the hexagonal socket of the bolt can clean the iron filings during the grinding process, improving the work efficiency.
