Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a grinding device for producing friction materials for torque limiters. Background Art

[0002] The friction plate is one of the more important parts in the torque limiter. In the existing technology, after the friction plate is produced, it is often necessary to grind it to ensure the uniform thickness of the friction plate surface and remove burrs on the friction disc surface, so as to achieve the required product quality. In the existing technology, when grinding the friction disc, generally only one side can be polished first. However, since the friction disc is double-sided, in order to remove burrs on both sides, the grinding disc with the ground one side needs to be removed, turned over, fixed, and then polished again. The overall work efficiency is low. Therefore, to address this problem, there is a need for an improved grinding device for the production of torque limiter friction materials. Utility Model Content

Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4 The present utility model provides a technical solution: a grinding device for producing torque limiter friction materials, comprising a base plate 1, with a fixed column 2 fixedly provided in the middle of the upper end of the base plate 1. Brackets 3 are fixedly provided at the four corners of the upper end surface of the base plate 1, and a top plate 4 is fixedly provided on the upper end of the bracket 3. A grinding mechanism is provided between the top plate 4 and the fixed column 2, and the grinding mechanism includes a lower grinding disc 5, a hydraulic cylinder 6, an upper grinding disc 7, a friction disc 10, a first electric push rod 8, and a second electric push rod 9. The lower grinding disc 5 is movably provided on the upper end of the fixed column 2 via a rotating shaft, a hydraulic cylinder 6 is fixedly provided in the middle of the top plate 4, and the upper grinding disc 7 is fixedly provided at the movable end of the hydraulic cylinder 6. The friction disc 10 is provided on the upper end of the lower grinding disc 5, and first electric push rods 8 are provided on both sides of the lower end of the lower grinding disc 5, and second electric push rods 9 are provided on both sides of the upper end of the upper grinding disc 7.

[0020] An electric motor 11 is fixedly provided at the upper end of the fixed column 2. The output shaft end of the electric motor 11 is connected to the rotating shaft of the lower grinding disc 5 through a coupling. The lower grinding disc 5 can be driven to rotate by the electric motor 11. When the friction disc 10 and the upper grinding disc 7 move relative to each other, the upper end surface of the friction disc 10 can be polished. Correspondingly, when the friction disc 10 and the lower grinding disc 5 move relative to each other, the lower end surface of the friction disc 10 can be polished.

[0021] A first mounting bracket 12 is fixedly provided on the outer side of the first electric push rod 8. The first mounting bracket 12 is fixedly connected to the lower grinding disc 5. The first motor 11 and the lower grinding disc 5 can be fixedly connected through the first mounting bracket 12.

[0022] A second mounting bracket 13 is fixedly provided on the outer side of the second electric push rod 9. The second mounting bracket 13 is fixedly connected to the upper grinding disc 7. The second mounting bracket 13 can be used to fix the second motor 11 and the upper grinding disc 7.

[0023] The outer surface of the friction disc 10 is provided with a mounting hole 14, which is a hole for mounting the friction disc 10 on the torque limiter. When used in conjunction with the present device, the first electric push rod 8 or the second electric push rod 9 can be extended or shortened so that the movable end of the first electric push rod 8 or the second electric push rod 9 is inserted into the mounting hole 14, thereby fixing the friction disc 10 and the lower grinding disc 5 or the upper grinding disc 7.

[0024] The movable end of the hydraulic cylinder 6 is fixedly connected to the upper grinding disc 7. The upper grinding disc 7 of the device can be tightly attached to the upper end surface of the friction disc 10 under the driving action of the hydraulic cylinder 6, or it can be away from the friction disc 10, so that the friction disc 10 can be easily removed. No matter which side of the friction disc 10 is ground, the upper grinding disc 7 of the device does not need to be moved.

[0025] Working principle: When using this device, the grinding principle of this device is as follows: the friction disc 10 to be ground is placed on the upper end of the lower grinding disc 5. At this time, the first electric push rod 8 is extended, so that the movable end of the first electric push rod 8 is slightly raised on the surface of the lower grinding disc 5. Then, the friction disc 10 is sleeved on the movable end of the first electric push rod 8 through the mounting hole 14. At this time, the friction disc 10 cannot rotate relative to the lower grinding disc 5, and no friction can occur. Then, the hydraulic cylinder 6 is extended to make the upper grinding disc 7 cooperate with the lower grinding disc 5 to clamp the friction disc 10, forming Figure 2 In the state shown, the lower grinding disc 5 is then driven to rotate by the motor 11. At this time, since the movable end of the first electric push rod 8 is inserted into the mounting hole 14, the rotation of the lower grinding disc 5 will drive the friction disc 10 to rotate together, so that relative friction occurs between the friction disc 10 and the upper grinding disc 7, and the upper end surface of the friction disc 10 can be ground.

[0026] After the upper surface of the friction disc 10 is processed, the first electric push rod 8 can be retracted so that the friction disc 10 and the lower grinding disc 5 are no longer fixed, and then the second electric push rod 9 can be extended so that the second electric push rod 9 can be inserted into the mounting hole 14, so that the friction disc 10 and the upper grinding disc 7 cannot rotate relative to each other. At this time, the motor 11 continues to drive the lower grinding disc 5 to rotate, so that the lower end surface of the friction disc 10 can be ground. In this way, the device can grind the upper and lower end surfaces of the friction disc 10 at one installation by driving the friction disc 10 to rub against the upper grinding disc 7 and the lower grinding disc 5 respectively, thereby eliminating one installation step and improving the grinding efficiency of the friction disc 10.
