Description

Technical Field

[0001] The utility model relates to the technical field of metal grinding, in particular to a grinding tool head for metal grinding. Background Art

[0002] Metal grinding is a type of surface modification technology, which generally refers to a processing method that uses rough objects (such as sandpaper containing higher hardness particles) to change the physical properties of the metal surface through friction. The main purpose is to obtain a specific surface roughness.

[0003] However, when the existing grinding head for metal grinding is used, the metal grinding head is usually connected to a metal fixing rod. After the blade head has been grinding metal for a long time, the surface of the blade head will be worn and the blade head needs to be replaced. The metal fixing rod on the blade head will be disassembled together with the blade head, resulting in a waste of resources. At the same time, when the blade head is grinding metal, the debris generated by the grinding will splash, and the splashed debris is easy to contact with the staff, resulting in low safety performance. Therefore, a grinding head for metal grinding is provided. Utility Model Content

[0004] The main purpose of the utility model is to provide a grinding cutter head for metal grinding. The utility model solves the problem that the existing grinding cutter head for metal grinding is inconvenient to disassemble and replace the cutter head body when in use, and it is inconvenient to cover the debris generated by the cutter head body when grinding metal, through the provision of a circular plate, a threaded sleeve, a fixing block, a limit sleeve A, a limit sleeve B, a spring A, a spring B, a limit block A and a limit block B.

[0005] The technical solution adopted by the utility model to solve its technical problems is a grinding cutter head for metal grinding, comprising a fixing rod and a cutter head body, a fixing block for limiting the cutter head body is welded on one side of the fixing rod, a threaded sleeve for fixing the cutter head body is connected to the outer thread of the fixing rod, a circular plate for shielding grinding debris is sleeved on the outer side of the fixing rod, a limiting sleeve A for limiting the circular plate is welded on the outer side of the circular plate, a limiting sleeve B is welded on the side of the circular plate away from the limiting sleeve A, a spring A connected to a support plate A is welded on the inner side of the fixing rod, a limiting block A for fixing the limiting sleeve A is welded on the outer side of the support plate A, a spring B connected to the support plate B is welded inside the fixing rod, and a limiting block B for fixing the limiting sleeve A is welded on one side of the support plate B.

[0006] By adopting the above technical solution, when the metal grinding cutter head needs to be replaced, the threaded sleeve outside the fixed rod is rotated, and then the threaded sleeve is separated from the cutter head body, and then the cutter head body is removed from the outside of the fixed rod, and then a new cutter head body is placed outside the fixed rod, and the fixed block outside the fixed rod contacts with the surface of the cutter head body, and then the threaded sleeve is placed outside the fixed rod, and the threaded sleeve is rotated to move the threaded sleeve outside the fixed rod, and then the threaded sleeve contacts with the surface of the cutter head body, so that the cutter head body is fixed outside the fixed rod, thereby facilitating the removal and replacement of the cutter head body;

[0007] When the cutter head body is grinding metal, the limit block A and the limit block B outside the fixed rod are pressed, the support plate A on one side of the limit block A presses the spring A, and the support plate B on the side of the limit block B presses the spring B, so that the limit block A and the limit block B enter the inside of the fixed rod, and then the limit sleeve A and the limit sleeve B are sleeved on the outside of the fixed rod, and the limit sleeve A and the limit sleeve B drive the circular plate to move outside the fixed rod, and then the spring A drives the limit block A on the side of the support plate A to clamp the limit sleeve A, and the spring B drives the limit block B on the support plate B to clamp the limit sleeve B. There are two groups of limit blocks A on the support plate A, and two groups of limit blocks B on the support plate B, so that the limit sleeve B on one side of the circular plate is limited, thereby facilitating the fixing of the circular plate on the outside of the fixed rod, and can block the debris generated by the grinding of metal by the cutter head body, thereby improving the safety performance.

[0008] Specifically, the surface of the limit sleeve A is symmetrically provided with through hole A and through hole B, and through hole A is located on the upper side of through hole B. The inner size of through hole A is consistent with the outer size of limit block A, and the inner size of through hole B is consistent with the outer size of limit block B.

[0009] By adopting the above technical solution, when the limit block A and the limit block B fix the limit sleeve A, the limit block A enters into the through hole A opened on the surface of the limit sleeve A, and the inner side of the through hole A coincides with the outer side of the limit block A. At the same time, the limit block B enters into the through hole B opened on the surface of the limit sleeve A, and the inner side of the through hole B coincides with the outer side of the limit block B, thereby improving the stability of the fixation of the limit block A.

[0010] Specifically, rubber pads for increasing the friction force on the cutter head body are bonded to the inner sides of the fixing block and the threaded sleeve.

[0011] By adopting the above technical solution, when the fixing block and the threaded sleeve fix the cutter head body, the rubber pad in the fixing block and the threaded sleeve increases the friction force on the cutter head body, thereby improving the stability of the fixation of the cutter head body.

[0012] Specifically, the surface of the threaded sleeve is provided with convex blocks for increasing the friction force of the threaded sleeve surface.

[0013] By adopting the above technical solution, when the threaded sleeve is driven to rotate, the convex blocks provided on the threaded sleeve increase the friction force on the surface of the threaded sleeve, thereby facilitating the rotation of the threaded sleeve.

[0014] Specifically, the surfaces of the spring A and the spring B are sprayed with anti-rust paint to increase the service life.

[0015] By adopting the above technical solution, moisture from the outside air can easily enter the interior of the fixed rod, and the surfaces of the spring A and spring B inside the fixed rod are sprayed with anti-rust paint to prevent corrosion of the spring A and spring B and increase the service life of the spring A and spring B.

When the main body of the grinding head is grinding metal, the limit block A and the limit block B outside the fixed rod are pressed, the support plate A on one side of the limit block A presses the spring A, and the support plate B on one side of the limit block B presses the spring B, so that the limit block A and the limit block B enter the inside of the fixed rod, and then the limit sleeve A and the limit sleeve B are sleeved on the outside of the fixed rod, and the limit sleeve A and the limit sleeve B drive the circular plate to move outside the fixed rod, and then the spring A drives the limit block A on one side of the support plate A to clamp the limit sleeve A, and the spring B drives the limit block B on the support plate B to clamp the limit sleeve B.

[0027] When the cutter head body 7 is grinding the metal, the limit block A3 and the limit block B15 outside the fixed rod 1 are pressed, the support plate A11 on one side of the limit block A3 presses the spring A12, and the support plate B14 on one side of the limit block B15 presses the spring B13, so that the limit block A3 and the limit block B15 enter the inside of the fixed rod 1, and then the limit sleeve A5 and the limit sleeve B16 are sleeved on the outside of the fixed rod 1, and the limit sleeve A5 and the limit sleeve B16 drive the circular plate 2 to move outside the fixed rod 1, and then the spring A 12 drives the limit block A3 on one side of the support plate A11 to clamp the limit sleeve A5, and the spring B13 drives the limit block B15 on the support plate B14 to clamp the limit sleeve B16.
