Description

A grinding wheel fixing seat for a grinding machine

Technical Field

The utility model relates to the technical field of grinding wheels, in particular to a grinding wheel fixing seat for a grinding machine.

Background Art

A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinders and polishers. Grinding machines can process materials with higher hardness, such as hardened steel, cemented carbide, etc.; they can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very small surface roughness, and can also perform high-efficiency grinding, such as high-power grinding.

Existing grinding wheels are generally arc ring disks, which are assembled on a turntable with bolts. This bolt-type assembly has limited stability and requires corresponding screw grooves to be opened on the grinding wheel in advance, which is less practical.

Therefore, we propose a grinding wheel fixing seat for a grinding machine.

Utility Model Content

In view of the deficiencies in the prior art, the utility model provides a grinding wheel fixing seat for a grinding machine, which solves the problem that the prior device needs to drill a hole on the grinding wheel, which is cumbersome to operate and has limited stability.

To achieve the above purpose, the utility model is implemented through the following technical solutions: a grinding wheel fixing seat for a grinding machine, comprising a driving motor and an output shaft shaft thereof, a rotating disk is mounted on the outer end of the rotating shaft, a screw groove is mounted at the center of the outer end surface of the rotating shaft, and a pressure ring with the same inner diameter specification as the grinding wheel is fixedly mounted on the outer wall of the rotating disk;

The outer side of the rotating disk is equipped with a counter disk, a grinding wheel is sandwiched between the rotating disk and the counter disk, and a stud matched with the specification of the screw channel is fixedly installed on the inner side wall of the counter disk.

Preferably, an inner protective ring located outside the pressure ring is fixedly mounted on the outer wall of the rotating disk, and an outer protective ring matching the specifications of the inner protective ring on the pressure ring is also mounted on the inner wall of the abutment disk.

Preferably, a chuck is fixedly welded to the outer end of the rotating shaft, and a clamping portion matching the specifications of the chuck is provided on the inner side of the rotating disk.

Preferably, the outer end surface of the chuck is serrated, and the inner side of the clamping portion is provided with a serrated groove with an open outer side.

Preferably, a tightening groove in the shape of a regular hexagonal groove is provided on the outer wall of the abutment plate.

The utility model provides a grinding wheel fixing seat for a grinding machine, which has the following beneficial effects:

The grinding wheel fixing seat for the grinder can remove the counter plate in advance through the arrangement of the components at the outer end of the rotating shaft, and then put the grinding wheel on the outer side of the pressure ring, and finally rotate the counter plate and cooperate with the stud to squeeze and limit the grinding wheel between it and the rotating plate to complete the assembly. In this way, the external pressure-type assembly does not require drilling of the grinding wheel, and there is no situation in which the bolts are loosened after long-term use and thus cause poor stability, which solves the problem that the existing device needs to open a hole on the grinding wheel, which is cumbersome and has limited stability.

DETAILED DESCRIPTION

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

Please refer to Figures 1-4. The embodiment of the utility model provides a technical solution: a grinding wheel fixing seat for a grinding machine, a driving motor and an output shaft 1 thereof, characterized in that: a turntable 2 is mounted on the outer end of the turntable 1, a screw groove 6 is mounted at the center of the outer end surface of the turntable 1, and a pressure ring 7 with the same inner diameter specification as the grinding wheel is fixedly mounted on the outer wall of the turntable 2;

The outer side of the rotating disk 2 is equipped with a contact plate 3, a grinding wheel is sandwiched between the rotating disk 2 and the contact plate 3, and a stud 9 matching the specification of the screw channel 6 is fixedly installed on the inner side wall of the contact plate 3;

Among them, in this embodiment, it is necessary to supplementally explain that the grinding wheel fixing seat for the grinder can pre-remove the contact plate 3 through the arrangement of the components at the outer end of the rotating shaft 1, and then put the grinding wheel on the outer side of the pressure ring 7, and finally rotate the contact plate 3 and cooperate with the stud 9 to squeeze and limit the grinding wheel between it and the rotating disk 2 to complete the assembly. In this way, the external pressure-type assembly does not require drilling holes in the grinding wheel, and there is no situation in which the bolts are loosened after long-term use, resulting in poor stability. The problem that the existing device needs to drill holes in the grinding wheel and the operation is cumbersome and the stability is limited.

In this embodiment, it should be additionally explained that an inner protective ring located outside the pressure ring 7 is fixedly mounted on the outer wall of the turntable 2, and an outer protective ring matching the specifications of the inner protective ring on the pressure ring 7 is also mounted on the inner wall of the abutment plate 3.
