Description

Technical Field

[0001] The utility model relates to the technical field of spiral groove grinding wheels, in particular to a spiral groove grinding wheel for machining gear tooth profiles. Background Art

[0002] The spiral groove grinding wheel is used to grind the gears, thereby improving the matching accuracy of the gears. During the processing, the gears are placed on the processing machine, and then the spiral groove grinding wheel is installed on the rotating shaft of the machine. The spiral groove grinding wheel is driven to rotate by the rotating shaft, and the spiral groove grinding wheel is driven to move at the same time, so as to grind the size.

[0003] Different diameters of spiral groove grinding wheels need to be replaced for gears of different specifications. The diameter of the spiral groove grinding wheel is much larger than the diameter of the rotating shaft of the machine tool. Therefore, the sleeve and the grinding wheel body often need to be fixed by a mounting bracket. The size of the sleeve is usually a universal fixed size, but due to the change in the diameter of the grinding wheel body, different specifications of mounting brackets are required. Since the mounting bracket is usually a fixed structure, that is, its size is difficult to adjust, it is necessary to set up mounting brackets of more specifications to match the grinding wheel body. The direct impact of setting up mounting brackets of more specifications is that the difficulty of warehousing classification is increased, the complexity of procurement or production is increased, and the difficulty of workpiece allocation is increased. This directly increases the difficulty of processing the spiral groove grinding wheel during actual production.

[0004] Therefore, a spiral groove grinding wheel for machining gear tooth profile is needed to overcome the occurrence of the above problems. Utility Model Content

[0005] In order to solve the above problems, the embodiment of the utility model provides a spiral groove grinding wheel for machining gear tooth profile, which achieves the purpose of solving the problems raised in the background technology.

[0007] As a further improvement of the above technical solution:

[0008] The telescopic assembly comprises a connecting tube fixedly connected to the outside of the shaft sleeve and a threaded rod threadedly connected to the inside of the connecting tube; a threaded groove used in conjunction with the threaded rod is provided inside the connecting block.

[0009] A limiting assembly for preventing the threaded rod from rotating is provided at the connection between the threaded rod and the connecting block.

[0010] The limiting assembly comprises a gear fixedly connected to the outside of the threaded rod, a bolt threadedly connected to one side of the connecting block, and a limiting block sleeved on the bolt.

[0011] The telescopic components are provided in two groups, and the two groups of telescopic components are respectively arranged at two ends of the shaft sleeve.

[0012] Each group of the telescopic components is provided with more than three.

[0013] The beneficial effects of the embodiments of the utility model are:

[0014] In actual use, the overall length of the telescopic assembly is adjusted by adjusting the telescopic assembly, so that the sleeve can be installed and fixed to the grinding wheel body of different diameters through the telescopic assembly with adjustable length, that is, there is no need to set a large number of specifications for the mounting frame, thereby reducing the difficulty of production and processing.

[0020] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0021] See also Figures 1 to 4 The embodiment of the utility model discloses a spiral groove grinding wheel for machining gear tooth profile, comprising a grinding wheel body 1 and a mounting frame 2 fixedly connected to the inside of the grinding wheel body 1, the inside of the grinding wheel body 1 is fixedly connected to a shaft sleeve 21 through the mounting frame 2, the mounting frame 2 comprises a telescopic assembly 22 arranged outside the shaft sleeve 21 for adapting to the grinding wheel body 1 with different inner diameters, and the inside of the grinding wheel body 1 is fixedly connected to a connecting block 3 used in conjunction with the telescopic assembly 22;

[0022] In actual use, the overall length of the telescopic assembly 22 is adjusted by adjusting the telescopic assembly 22, so that the sleeve 21 can be installed and fixed to the grinding wheel body 1 of different diameters through the telescopic assembly 22 with adjustable length, that is, there is no need to set a large number of specifications for the mounting frame, thereby reducing the difficulty of production and processing.

[0023] As a further illustration of this application:

[0024] The telescopic assembly 22 includes a connecting tube 221 fixedly connected to the outside of the shaft sleeve 21, and a threaded rod 222 threadedly connected to the inside of the connecting tube 221; a threaded groove used in conjunction with the threaded rod 222 is provided inside the connecting block 3;

[0025] In actual use, the length of the threaded rod 222 extending from the connecting tube 221 is adjusted by rotating the threaded rod 222, so that the threaded rod 222 is connected to the connecting block 3, and the threaded rod 222 is threadedly connected inside the thread groove, thereby realizing a fixed connection between the mounting frame 2 and the grinding wheel body 1.

[0026] As a further illustration of this application:

[0027] A limit assembly 4 is provided at the connection between the threaded rod 222 and the connecting block 3 to prevent the threaded rod 222 from rotating. The limit assembly 4 includes a gear 41 fixedly connected to the outside of the threaded rod 222, a bolt 42 threadedly connected to one side of the connecting block 3, and a limit block 43 sleeved on the bolt 42.

[0028] After the threaded rod 222 is completely screwed into the threaded groove, the gear 41 is flush with the stop block 43, and then the bolt 42 is rotated so that the stop block 43 is stuck on the outside of the gear 41, and the gear 41 can be limited by the stop block 43, thereby preventing the gear 41, that is, preventing the threaded rod 222 from rotating;

[0029] The limit block 43 is an arc-shaped block with teeth on one side, which is coaxially arranged with the gear 41; since the depth of the thread groove is determined, after the threaded rod 222 is completely screwed into the thread groove, that is, the threaded rod 222 is screwed into place, the upper and lower sides of the gear 41 and the limit block 43 are aligned, so it is possible to judge whether the threaded rod 222 is completely screwed into place by the positional relationship between the gear 41 and the limit block 43.

[0030] As a further illustration of this application:

[0031] There are two groups of telescopic assemblies 22 , which are respectively arranged at both ends of the shaft sleeve 21 . Since the grinding wheel body 1 has a certain length, the telescopic assemblies 22 are arranged at both ends of the shaft sleeve 21 , so as to facilitate the adjustment of the telescopic assemblies 22 .

[0032] As a further illustration of this application:

[0033] Each group of telescopic components 22 is provided with more than three. After the three or more telescopic components 22 cooperate with the connecting block 3, it can be ensured that the sleeve 21 and the grinding wheel body 1 are set to be coaxial.
