[0002] In modern industrial production, the demand for high-precision products is growing, such as engine crankshafts, camshafts that control intake and exhaust, etc. The surface roughness and other parameters of these products need to meet strict requirements. In order to achieve this goal, polishing has become an indispensable link. However, the width of the polishing journal required for different products varies, which requires us to cut the sanding belts of the same width purchased uniformly into sanding belts of different widths according to the needs of different workpieces to reduce waste and reduce costs.

[0003] However, in actual operation, the existing abrasive belt cutting devices have certain limitations. First, in terms of cutting efficiency, the existing devices often cannot meet the high-efficiency production requirements. Secondly, due to the structural design problems of the device, the abrasive belt is easily damaged during the cutting process, which not only affects the product quality but also increases the production cost. Therefore, in order to solve these problems and improve the efficiency and quality of abrasive belt cutting, the utility model proposes an abrasive belt cutting device for precision polishing.

The utility model has a simple structure, is easy to operate and maintain.

[0005] To achieve the above-mentioned purpose, the technical solution provided by the utility model is as follows: a sanding belt cutting device for precision polishing, comprising at least a sanding belt, a supporting platform, a motor for driving the sanding belt and a blade for cutting the sanding belt, a pair of sanding belt brackets A and a sanding belt bracket B that cooperate with each other are arranged on the plane of the supporting platform, the sanding belt bracket A and the sanding belt bracket B are both disc structures, and the sanding belt is wound between the two sanding belt brackets;

[0006] A baffle is provided on the upper part of the support platform, and a blade group parallel to the support platform is provided behind the baffle, wherein the blade group is composed of at least mutually parallel blades and pads arranged between the blades, and the blades and pads are fixed to the support platform by locking bolts, and the height of the pads matches the size of the workpiece to be polished; the bottom support platform is provided with a motor for driving the sanding belt bracket B, and the motor is coaxially installed with the disc-shaped sanding belt bracket B.

[0007] The baffle is a disc-shaped structure and is located above the abrasive belt support A, so that the abrasive belt can stably pass through the blade assembly.

[0008] The width of the pad is determined according to the width required for polishing the workpiece. The blade position is fixed and locked by matching the locking bolt and the pad. The width of the abrasive belt is controlled by adjusting the width between the blades.

[0009] According to the above technical solution, the utility model provides a sanding belt cutting device for precision polishing. The sanding belt is rolled up by the sanding belt bracket A and the sanding belt bracket B on the support platform. The sanding belt passes through the blade group through the baffle. The width between the blades is adjusted to control the width of the sanding belt through the parallel blades and the pads determined according to the polishing needs of the workpiece. The sanding belt is quickly cut by driving the motor of the sanding belt bracket B. Compared with the prior art, the utility model has the following advantages:

[0010] (1) Because the technical solution adopted by the utility model determines the height of the pad according to the needs of workpiece polishing and adjusts the width of the required cut sanding belt by the width of the blade group, the utility model can flexibly adjust the parameters of the device according to the workpiece size and polishing requirements to achieve high-quality polishing effect.

[0011] (2) Because the technical solution adopted by the utility model only determines the width of the sanding belt by adjusting the blade group, and the sanding belt is driven by the motor to achieve rapid cutting, the utility model can quickly cut the rolled sanding belt to ensure that the width of the cut sanding belt is consistent, thereby reducing the cost of use. In addition, the structure is simple, which is easy to repair and maintain, thereby reducing the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS
