Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Embodiment: This embodiment discloses an efficient grinding device for the end of a hardware part, as Figures 1-7 shown, including: a frame 100, a grinding mechanism 200, and a moving clamping mechanism 400; both the grinding mechanism 200 and the moving clamping mechanism 400 are fixedly installed on the frame 100. The grinding mechanism 200 includes a base 201, a driving motor 202 and a bearing seat 212 fixedly installed on the base 201. The base 201 is fixedly connected to the frame 100. The bearing seat 212 is rotatably connected to a rotating shaft 203. The driving motor 202 is used to drive the rotating shaft 203 to rotate. Among them, a first pulley 204 is fixedly installed at one end of the rotating shaft 203, and a second pulley 206 is fixedly connected to the rotating shaft of the driving motor 202. A belt line 205 is connected between the first pulley 204 and the second pulley 206; a grinding wheel 207 is fixedly connected to one end of the rotating shaft 203, and the grinding wheel 207 is used to grind and polish the surface of the hardware part.

[0026] As Figures 3-5 shown, a circular groove 209 is provided on the surface of the grinding wheel 207, and an end grinding component 300 is installed inside the groove 209. When the grinding wheel 207 rotates, it drives the end grinding component 300 to rotate; the end grinding component 300 includes a circular fixing frame 301, the fixing frame 301 is fixedly installed in the groove 209, and a plurality of chutes 304 facing the center direction of the fixing frame 301 are provided on the surface of the fixing frame 301. The chutes 304 are evenly distributed along the circumferential direction of the fixing frame 301, and a slider 302 is slidably connected in the chute 304. A grinding piece 303 is fixedly installed on the slider 302. In this embodiment, the number of grinding pieces 303 is four; the end grinding component 300 further includes an annular piece 305, and a connecting rod 306 is hinged between the annular piece 305 and the slider 302. When the annular piece 305 moves, it drives the slider 302 to slide in the chute 304, thereby adjusting the position of the grinding piece 303.

[0027] One end of the rotating shaft 203 is fixedly connected with a first screw rod 2031. The diameter of the first screw rod 2031 is smaller than that of the rotating shaft 203. The first screw rod 2031 penetrates through the grinding wheel 207, and the grinding wheel 207 is fixedly installed on the first screw rod 2031 through a nut. The fixing frame 301 is also fixedly installed on the first screw rod 2031, and a first nut 208 for fastening the fixing frame 301 is fixedly connected to the first screw rod 2031, so that the fixing frame 301 is stably installed in the groove 209. A second screw rod 2032 is fixedly connected to the first screw rod 2031. The diameter of the second screw rod 2032 is smaller than that of the first screw rod 2031. The annular member 305 is slidably connected to the second screw rod 2032. A cylindrical spring 307 and a second nut 211 are respectively connected to the surface of the second screw rod 2032. The cylindrical spring 307 and the second nut 211 are respectively arranged on two side surfaces of the annular member 305. The cylindrical spring 307 is arranged between the annular member 305 and the end face of the first screw rod 2031. The cylindrical spring 307 applies an outward elastic force to the annular member 305, and the position of the annular member 305 is limited by the second nut 211, so that the position of the annular member 305 is stable. By rotating the second nut 211 with a wrench, the annular member 305 can be driven to move, and then the position of the grinding member 303 can be adjusted.

[0028] Such as Figure 6As shown, the grinding part 303 is respectively provided with a flat part 3031 for grinding the end face of the pipe fitting, a conical part 3032 for grinding the inner wall of one end of the pipe fitting, and an arc part 3033 for grinding and polishing the inner wall of the pipe fitting. Among them, the conical part 3032 is mainly used for deburring the inner wall of the pipe fitting, and the arc part 3033 is mainly used for grinding and polishing the inner wall of the pipe fitting. And a grinding block 3034 for grinding the outer wall of one end of the pipe fitting is fixedly connected to the grinding part 303. The grinding block 3034 is an arc-shaped block, and enough space is left between the grinding block 3034 and the arc part 3033. During specific implementation: Rotate the second nut 211 through a wrench to drive the annular part 305 to move, and then adjust the position of the grinding part 303. When it is necessary to polish and grind the inner wall of the metal pipe fitting, adjust the position of the grinding part 303 so that the conical part 3032 or the arc part 3033 can contact the inner wall of the metal pipe fitting. When it is necessary to polish and grind the outer wall of the metal pipe fitting, adjust the position of the grinding part 303 so that the inner surface of the grinding block 3034 can contact the inner wall of the metal pipe fitting. When it is necessary to polish and grind the end face of the metal pipe fitting, adjust the position of the grinding part 303 so that the flat part 3031 can contact the end face of the metal pipe fitting. At this time, the metal pipe fitting does not contact the grinding block 3034 and the arc part 3033. During the grinding process, control the moving clamping mechanism 400 to drive the metal pipe fitting to slowly approach the end grinding assembly 300. Among them, when adjusting the position of the grinding part 303, in order to make its position accurate, scale lines with different diameters are provided on the fixing frame 301. When grinding pipe fittings with different diameters, move the designated part of the grinding part 303 to the corresponding scale line. For example, when polishing the inner wall of the pipe fitting, the arc part 3033 on the grinding part 303 can be moved to the corresponding scale line. The grinding equipment in this embodiment can simultaneously grind and polish the outer wall, inner wall and end face of one end of the metal pipe fitting, and the metal pipe fitting does not need to rotate during the grinding process, so that the grinding efficiency of the metal pipe fitting is increased.

[0029] Preferably, a plurality of limiting blocks 210 are evenly arranged along the circumferential direction of the groove 209, and a limiting groove 309 cooperating with the limiting blocks 210 is provided on the fixing frame 301. By clamping the limiting groove 309 on the limiting blocks 210, the position of the fixing frame 301 in the groove 209 is ensured to be stable, and the fixing frame 301 is prevented from shifting when the grinding wheel 207 rotates at a high speed. A connecting rod 308 is vertically and fixedly connected to the slider 302, a connecting hole 3035 cooperating with the connecting rod 308 is provided on the grinding part 303, and a nut is connected to the connecting rod 308 to fixedly install the grinding part 303 on the slider 302.

[0030] Such as Figure 7As shown in the figure, the moving clamping mechanism 400 includes a sliding seat 406. A mounting bracket 403 is fixedly connected to the sliding seat 406. A three-jaw chuck 404 is fixedly connected to the mounting bracket 403 by a bolt assembly for clamping and fixing the pipe fitting. The three-jaw chuck 404 is a prior art. The center of the three-jaw chuck 404 and the center of the end grinding assembly 300 are on the same horizontal line, that is, their center lines coincide. The moving clamping mechanism 400 further includes a slide rail 401 and a threaded rod 402 mounted on the slide rail 401. The slide rail 401 is fixedly installed on the frame 100. The sliding seat 406 is slidably connected to the slide rail 401 and is threadedly connected to the threaded rod 402. One end of the threaded rod 402 is fixedly connected to a handle 405. By rotating the threaded rod 402, the sliding seat 406 can be driven to move, driving the hardware pipe fitting to move.

[0031] This embodiment also discloses an efficient grinding method for the end of a hardware part. Based on the above grinding equipment, it includes the following steps: Inner wall grinding of the end: Clamp and fix the pipe fitting on the three-jaw chuck 404. Adjust the position of the grinding part 303 by adjusting the second nut 211 so that the inner wall of the end of the pipe fitting can contact the conical surface part 3032 or the arc surface part 3033. Start the driving motor 202 to drive the end grinding assembly 300 to rotate. Drive the hardware pipe fitting to approach the grinding wheel 207 by controlling the moving clamping mechanism 400 to grind the inner wall of the end of the pipe fitting. Outer wall grinding of the end: Adjust the position of the grinding part 303 by adjusting the second nut 211 so that the outer wall of the end of the pipe fitting can contact the surface of the grinding block 3034. Start the driving motor 202 to drive the end grinding assembly 300 to rotate. Drive the hardware pipe fitting to approach the grinding wheel 207 by controlling the moving clamping mechanism 400 to grind the outer wall of the end of the pipe fitting. End face grinding: Adjust the position of the grinding part 303 by adjusting the second nut 211 so that the end face of the pipe fitting can contact the flat surface part 3031. Start the driving motor 202 to drive the end grinding assembly 300 to rotate. Drive the hardware pipe fitting to approach the grinding wheel 207 by controlling the moving clamping mechanism 400 to grind the end face of the pipe fitting.
