Description

Technical Field

[0001] This utility model relates to the field of fixed tooling technology, specifically a fixed tooling for grinding a grinding wheel substrate. Background Technology

[0002] Before grinding the grinding wheel base, the positioning plate needs to be fixed by the chuck on the grinding machine. The outer wall of one side of the positioning plate is provided with threaded holes and annular positioning grooves. Then, the grinding wheel base is placed on the outer wall of the positioning plate. The annular positioning grooves can help align the grinding wheel with the center of the positioning plate. Then, the grinding wheel base is fixed on the positioning plate with bolts. The grinding machine is then used to drive the grinding wheel base to rotate and grind.

[0003] Because the positioning plate is vertically fixed, when placing the grinding wheel base on the outer wall of the positioning plate for fixing, one person needs to hold the grinding wheel base by hand while another person fixes it with bolts. The operation is quite troublesome. In addition, when fixing the grinding wheel base with bolts, it is also necessary to rotate the grinding wheel base to make it easy to align the threaded hole on the grinding wheel base with the threaded hole on the outer wall of the positioning plate, which further increases the workload of holding the grinding wheel base. Utility Model Content

[0004] The purpose of this utility model is to provide a fixed fixture for grinding a grinding wheel substrate, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed fixture for grinding a grinding wheel substrate, comprising: a positioning disk, a grinding wheel substrate and a hexagonal prism, and further comprising: a fixed shell installed on one side of the outer wall of the positioning disk, a support plate installed on the inner wall of the positioning disk, and a propulsion component rotatably installed on one side of the outer wall of the support plate, a plurality of equally spaced sliding grooves opened on one side of the outer wall of the positioning disk, and a drive component slidably connected to the inner wall of the sliding grooves, and a plurality of equally spaced limiting components installed on the arc-shaped outer wall of the positioning disk.

[0006] The propulsion assembly includes a threaded rod, a movable block screwed onto the threaded rod, multiple equally spaced propulsion rods rotatably mounted on the outer wall of the movable block, and a hexagonal block mounted on one end of the threaded rod, with a hexagonal groove on one side of the outer wall of the hexagonal block.

[0007] The drive assembly includes a slider and a rack mounted on the top outer wall of the slider.

[0008] The limiting assembly includes two fixed plates, a rotating shaft rotatably connected between the two fixed plates, a gear mounted on the outer wall of the rotating shaft, a mounting bracket mounted on the outer wall of the rotating shaft, and a rotating roller rotatably mounted on the inner wall of the mounting bracket.

[0009] A crossbar is fixed to the top of the hexagonal prism.

[0010] The rack meshes with the gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model discloses a fixing fixture for grinding a grinding wheel substrate. When the grinding wheel substrate is placed on the outer wall of the positioning plate, the setting limit component can support the grinding wheel substrate without the need for workers to lift it. At the same time, it is convenient to rotate the grinding wheel substrate and adjust the threaded hole on the grinding wheel substrate to align with the threaded hole on the outer wall of the positioning plate. Only one person is needed to complete the operation, which is more convenient. After the grinding wheel substrate is fixed, the limit component can be rotated by rotating the propulsion component to drive it to flip over, so that the limit component can be removed from the outer wall of the grinding wheel substrate, so as to avoid affecting the movement of the grinding wheel on the outer wall of the grinding wheel substrate during subsequent grinding.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 The present invention provides a fixed fixture for grinding a grinding wheel substrate, comprising: a positioning disk 3, a grinding wheel substrate 5 and a hexagonal prism 11, and further comprising: a fixed shell 4 installed on one side of the outer wall of the positioning disk 3, a support plate 6 installed on the inner wall of the positioning disk 3, and a propulsion component 7 rotatably installed on one side of the outer wall of the support plate 6, a plurality of equally spaced sliding grooves 8 opened on one side of the outer wall of the positioning disk 3, and a drive component 9 slidably connected to the inner wall of the sliding grooves 8, and a plurality of equally spaced limiting components 10 installed on the arc-shaped outer wall of the positioning disk 3.

[0022] It should be noted that the chuck 2 on the grinding machine tool 1 can be used to clamp and fix the fixed shell 4, thereby fixing the positioning plate 3. The grinding wheel base 5 can be placed on the outer wall of the positioning plate 3. The limiting component 10 can support the grinding wheel base 5, preventing it from sliding downwards without the need for manual lifting. This also facilitates the rotation of the grinding wheel base 5, allowing for alignment of the threaded hole on the grinding wheel base 5 with the threaded hole on the outer wall of the positioning plate 3. Finally, the grinding wheel base 5 is fixed to the positioning plate 3 with bolts. The operation can be completed on the positioning plate 3 by one person, which is more convenient. After the grinding wheel base 5 is fixed, the hexagonal prism 11 can be inserted into one end of the propulsion component 7 and rotated to drive the propulsion component 7 to rotate. The propulsion component 7 can simultaneously drive multiple drive components 9 to move closer to each other, and then simultaneously drive multiple limit components 10 to flip to the side of the fixed shell 4, so that the limit components 10 are moved away from the outer wall of the grinding wheel base 5, so as to avoid affecting the movement of the grinding wheel on the outer wall of the grinding wheel base 5 during the subsequent grinding process.

[0023] In a preferred embodiment, the propulsion assembly 7 includes a threaded rod 701, a movable block 702 screwed onto the threaded rod 701, a plurality of equally spaced propulsion rods 703 rotatably mounted on the outer wall of the movable block 702, and a hexagonal block 704 mounted on one end of the threaded rod 701, wherein a hexagonal groove is formed on one side of the outer wall of the hexagonal block 704.

[0024] It should be noted that the hexagonal prism 11 can be inserted into the hexagonal slot. The hexagonal prism 11 can be rotated to drive the threaded rod 701 to rotate, which in turn drives the hexagonal block 704 to move. In turn, the four push rods 703 simultaneously pull the four drive components 9 to move.

[0025] In a preferred embodiment, the drive assembly 9 includes a slider 901 and a rack 902 mounted on the top outer wall of the slider 901.

[0026] It should be noted here that the push rod 703 can pull the slider 901 and the rack 902 to move.

[0027] In a preferred embodiment, the limiting assembly 10 includes two fixed plates 1001, a rotating shaft 1002 rotatably connected between the two fixed plates 1001, a gear 1003 mounted on the outer wall of the rotating shaft 1002, a mounting bracket 1004 mounted on the outer wall of the rotating shaft 1002, and a rotating roller 1005 rotatably mounted on the inner wall of the mounting bracket 1004.

[0028] It should be noted that when the racks 902 move closer to each other, they can drive the gears 1003 to rotate in the direction of the racks 902, thereby causing the mounting bracket 1004 to flip, so that the roller 1005 moves away from the outer wall of the grinding wheel base 5.

[0029] In a preferred embodiment, a crossbar 1101 is fixed to the top of the hexagonal prism 11.

[0030] It should be noted here that the hexagonal prism 11 is designed for easy rotation.

[0031] In a preferred embodiment, rack 902 meshes with gear 1003.

[0032] It should be noted here that the movement of rack 902 can drive gear 1003 to rotate.

[0033] Working principle: The chuck 2 on the grinding machine tool 1 can be used to clamp and fix the fixed shell 4, thereby fixing the positioning plate 3. The grinding wheel base 5 can be placed on the outer wall of the positioning plate 3. The set roller 1005 can support the grinding wheel base 5 and prevent it from sliding downwards. No operator is required to lift it. At the same time, it is convenient to rotate the grinding wheel base 5 and adjust the threaded hole on the grinding wheel base 5 to align with the threaded hole on the outer wall of the positioning plate 3. Then, the grinding wheel base 5 can be fixed on the positioning plate 3 with bolts. Only one person is needed to complete the operation, which is more convenient.

[0034] After the grinding wheel base 5 is fixed, the hexagonal prism 11 can be inserted into the hexagonal groove. The hexagonal prism 11 can be rotated to drive the threaded rod 701 to rotate, which in turn drives the hexagonal block 704 to move. Then, the four push rods 703 simultaneously pull the four sliders 901 and the four racks 902 closer to each other. When the racks 902 move, they can drive the gear 1003 to rotate in the direction of the racks 902, which in turn drives the mounting frame 1004 to flip, so that the roller 1005 is removed from the outer wall of the grinding wheel base 5, so as to avoid affecting the movement of the grinding wheel on the outer wall of the grinding wheel base 5 during the subsequent grinding process.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
