DETAILED DESCRIPTION

[0036] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, the purpose of this embodiment is to provide a metal product grinding processing device based on multi-directional numerical control, including a processing table 100, a processing group 200, and an internal and external grinding mechanism 300;

[0038] Support columns 101 are provided at both ends of the processing table 100, one of the support columns 101 is fixedly connected to the processing group 200, and the other support column 101 is fixedly connected to the inner and outer grinding mechanism 300;

[0039] The processing group 200 includes a holder 205 for fixing the workpiece and a driving member; the driving member is used to drive the holder 205 to reciprocate along the axis of the top end of the support column 101, and drive the holder 205 to rotate during the reciprocating motion;

[0040] The inner and outer grinding mechanism 300 includes an inner grinding group, an outer grinding group and a fixed shaft 302. The outer grinding group is arranged at one end of the fixed shaft 302 close to the processing group 200, and the inner grinding group is arranged at one end of the outer grinding group close to the processing group 200.

[0041] The outer grinding group is used to grind the outer surface of the pipeline workpiece. The inner grinding group is movably connected to the outer grinding group. When the driving member drives the holder 205 to reciprocate, the inner surface of the pipeline workpiece contacts the inner grinding group for grinding, and drives the inner grinding group to move toward the outer grinding group. The inner grinding group drives the outer grinding group to approach the pipeline workpiece to grind the outer surface of the pipeline workpiece.

[0042] The pipe workpiece is clamped and connected by the clamping seat 205, and the pipe workpiece is rotated and extended to the side of the inner grinding group surface by the clamping seat 205, and the inner wall of the pipe workpiece is ground around. At the same time, the inner grinding group continues to generate thrust, so that the inner grinding group drives the pipe workpiece to move toward the side of the outer grinding group, effectively making the outer surface of the pipe workpiece contact with the surface of the outer grinding group. While the pipe workpiece rotates, the outer surface of the pipe workpiece is ground around.

[0043] Therefore, based on the above structure, combined with Figure 1 and Figure 4 The structure of the processing group 200 is further disclosed as shown, and the processing group 200 includes a protection box 203, the protection box 203 is installed on one side of the surface of one of the support columns 101, a reciprocating motor 204 is installed on the surface of the protection box 203, a turbine 208 is installed inside the protection box 203, a shaft seat 206 is installed on the upper surface of the protection box 203, a worm 207 is rotatably sleeved on one side of the shaft seat 206, a clamping seat 205 is fixedly connected to one side of the surface of the worm 207, and a positioning rod 209 is fixedly connected to the center position of the clamping seat 205;

[0044] Furthermore, by clamping one side of the surface of the pipe workpiece on the surface of the clamping seat 205, starting the reciprocating motor 204, driving the turbine 208 to rotate at a high speed, and the outer surface of the worm 207 is provided with racks around, and the racks and the gears are meshed, thereby driving the worm 207 to telescope and rotate on one side of the surface of the shaft seat 206, thereby driving the pipe workpiece clamped on the surface of the clamping seat 205 to synchronously telescope and rotate at a high speed, and extending to one side of the surface of the grinding head 305, so as to grind one side of the surface of the pipe workpiece;

[0045] The improvement lies in that the reciprocating motor 204 is used to reciprocate the turbine 208. Under the meshing effect of the teeth and the rack, the worm 207 drives the holder 205 to rotate at high speed, and at the same time, an extension effect can be achieved, so that the pipe workpiece clamped by the holder 205 can be ground on one side of the surface of the grinding head 305.

[0046] Based on the above structure, combined with Figure 2-4As shown in the figure, the structure of the outer grinding group is further disclosed, the outer grinding group includes a fixed shaft 302, the fixed shaft 302 is fixedly mounted on one side of the upper surface of one of the support columns 101, a sleeve column 303 is fixedly mounted on one side of the surface of the fixed shaft 302, a sleeve rod 304 is telescopically sleeved on one side of the surface of the sleeve column 303, a grinding head 305 is mounted on one side of the surface of the sleeve rod 304, a limiting groove 310 is provided on one side of the surface of the grinding head 305, and a contact disc 315 is connected to one side of the surface of the sleeve rod 304;

[0047] Furthermore, the pipeline workpiece is clamped on the surface of the clamping seat 205, and the turbine 208 and the worm 207 are used to rotate the pipeline workpiece at high speed and extend it to the surface of the grinding head 305, so that the inner wall of the pipeline workpiece is ground around. At the same time, the turbine 208 and the worm 207 continue to rotate to move the clamping seat 205 toward the surface of the grinding head 305, and the positioning rod 209 is used to squeeze the grinding head 305, so that the sleeve rod 304 is telescopically sleeved on one side of the sleeve column 303 surface, and finally the grinding head 305 is clamped on the surface of the sleeve column 303 through the limiting groove 310.

[0048] The improvement lies in that the sleeve rod 304 and the sleeve column 303 can be used to allow the holder 205 to adjust the extrusion force generated by the grinding head 305. When the limit groove 310 and one side of the surface of the sleeve column 303 are clamped, the position of the grinding head 305 is fixed. At the same time, the contact disc 315 is affected by the movement of the sleeve rod 304 in the sleeve column 303, which facilitates the subsequent grinding of the outer surface of the pipeline workpiece.

[0049] Based on the above structure, combined with Figure 5-Figure 10 As shown, the structure of the inner grinding group is further disclosed, the inner grinding group includes a groove 306, the groove 306 is provided at the upper and lower ends of the outer surface of the sleeve 303, the inner walls of the groove 306 are connected to the return spring 307, one side of the return spring 307 is connected to the contact plate 308, and the upper surface of the contact plate 308 is installed with a side grinding ring 309;

[0050] Two grooves 311 are provided at both ends of the outer surface of the sleeve 303, and two return springs 312 are connected to the inner walls of the two grooves 311, one side of the surface of the two return springs 312 is connected to the second contact plate 313, and one side of the upper surface of the second contact plate 313 is connected to a protective ring 314, and the two sides of the surface of the protective ring 314 are parallel to the two sides of the surface of the side grinding ring 309;

[0051] Furthermore, the sleeve rod 304 is sleeved on one side of the sleeve column 303 to drive the contact disc 315 to move synchronously inside the sleeve column 303 and contact one side of the surface of the contact plate 308. Under the connection of the return spring 307, one side of the surface of the contact plate 308 is tilted, so that the side grinding ring 309 is tilted on both sides of the upper and lower outer surfaces of the sleeve column 303, and the pipeline workpiece presses the grinding head 305 to one side of the sleeve column 303 surface. When the pipeline workpiece rotates at a high speed, the surface of the side grinding ring 309 is in contact with the outer surface of the pipeline workpiece, and the outer surface of the pipeline workpiece is ground at a high speed.

[0052] At the same time, the contact disc 315 contacts one side of the surface of the second contact plate 313. Under the connection of the second return spring 312, the surface of the second contact plate 313 is made to be tilted, and the protection ring 314 is simultaneously tilted on both sides of the outer surface of the sleeve column 303, so that the sparks generated during the grinding process of the outer surface of the pipeline workpiece by the side grinding ring 309 are blocked;

[0053] The improvement is that: the contact disc 315 is used to squeeze the contact plate 308, so that one side of the surface of the contact plate 308 is tilted, driving the side grinding ring 309 to tilt synchronously, and rub against the outer surface of the pipe workpiece at high speed around, so as to grind the outer surface of the pipe workpiece;

[0054] The protection ring 314 is synchronously tilted with the side grinding ring 309, and the diameter and thickness of the protection ring 314 are larger than those of the side grinding ring 309. Therefore, the sparks generated during the grinding process around the side grinding ring 309 and the outer surface of the pipeline workpiece are blocked and protected to a certain extent.

[0055] In summary, the working principle of this scheme is as follows: the pipe workpiece is clamped and connected by the clamping seat 205, the reciprocating motor 204 is started, and the turbine 208 is driven to rotate at a high speed. The outer surface of the worm 207 is provided with racks around, and the racks and the gears are meshed, thereby driving the worm 207 to telescope and rotate on one side of the surface of the shaft seat 206, thereby driving the pipe workpiece clamped on the surface of the clamping seat 205 to synchronously telescope and rotate at a high speed, and extend to one side of the surface of the grinding head 305, and grinding one side of the surface of the pipe workpiece;

[0056] The pipe workpiece clamped by the holder 205 continues to move toward the side of the grinding head 305, and the positioning rod 209 is used to generate a thrust on the grinding head 305, thereby driving the sleeve rod 304 to move toward the inner side of the sleeve column 303, so that thrust is generated around the surface of the contact disc 315 and the inner end of the contact plate 1 308 and the contact plate 2 313, and under the action of the return spring 1 307 and the return spring 2 312, the outer end of the contact plate 1 308 and the contact plate 2 313 is effectively tilted, and then the side grinding ring 309 and the protective ring 314 are tilted toward the surface of the grinding head 305, and the side grinding ring 309 is used to grind the outer surface of the pipe workpiece clamped on the surface of the holder 205. At the same time, the sparks generated can be blocked by the protective ring 314, which has a certain protective effect.
