Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a replaceable sanding belt adjustment structure for a grinding machine. Background Technology

[0002] The belt adjustment mechanism of a grinder is a core functional component in the grinder system used for precise control of the belt's working state. Its main function is to adjust the belt used for grinding and polishing. By fine-tuning the lateral position of the belt, it corrects the tendency of the belt to deviate during operation due to factors such as installation deviation and uneven force, ensuring that the belt always conforms to the preset processing trajectory of the workpiece.

[0003] In the actual operation of a belt sander, the effective contact area of ​​the sanding belt must be precisely adjusted according to the specific size, shape, and surface treatment requirements of the object to be sanded, in order to ensure that the sanding accuracy and surface quality meet the standards. Achieving adaptability adjustment of the sanding area requires custom-made planar adjustment components for different sanding requirements. This customization process not only increases the research and development and manufacturing costs of parts but also increases the overall production and assembly complexity of the equipment, ultimately leading to a significant increase in the comprehensive cost of the sanding equipment. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that grinding machines need to adjust the sanding area of ​​the sanding belt according to the sanding surface of the object to be ground, and that it is necessary to customize a corresponding plane adjustment component in order to adjust the sanding area of ​​the sanding belt, thereby increasing the cost of grinding equipment. Therefore, a replaceable sanding belt adjustment structure for grinding machines is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a replaceable sanding belt adjustment structure for a grinder, comprising a first mounting frame and a second mounting frame. The second mounting frame is fixedly installed on one side of the first mounting frame. A drive assembly is fixedly connected to one end of the first mounting frame, and an adjustment frame is fixedly connected to one end of the second mounting frame. A guide wheel is drivenly connected to one end of the adjustment frame. The drive end of the drive assembly is drivenly connected to the outer side of the guide wheel and the sanding belt body is drivenly connected to it. A grinding surface adjustment assembly is fixedly connected to the other end of the first mounting frame. The grinding surface adjustment assembly includes a mounting side plate, two adjustment plates, a rotating rod, and a second guide wheel. The two adjustment plates are respectively movably engaged at both ends of the mounting side plate. The rotating rod is fixedly installed at one end of one side of the adjustment plate, and the second guide wheel is rotatably connected to the outer side of the rotating rod.

[0006] Preferably, several guide rods are fixedly connected to both ends of the mounting side plate, and several guide grooves are opened inside the adjusting plate, with several guide rods moving through the inside of the guide grooves.

[0007] Preferably, the guide rod has a plurality of positioning holes inside, and the guide groove has positioning grooves on both sides. The positioning holes are movably inserted through the positioning rod, and the other end of the positioning rod is movably inserted through the positioning groove.

[0008] Preferably, a washer is movably inserted through the outer side of one end of the positioning rod, the washer is fitted to one side of the adjusting plate, and a nut is threaded to one end of the positioning rod.

[0009] Preferably, a washer is movably inserted through the outer side of one end of the positioning rod, the washer is fitted to one side of the adjusting plate, and a nut is threaded to one end of the positioning rod.

[0010] Preferably, a washer is movably inserted through the outer side of one end of the positioning rod, the washer is fitted to one side of the adjusting plate, and a nut is threaded to one end of the positioning rod.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by adjusting the distance between the plate and the mounting side plate, the distance between the two guide wheels is increased, thereby expanding the area of ​​the grinding surface. There is no need to customize a special grinding surface adjustment component to adjust the grinding area, thus reducing equipment costs.

[0012] 2. In this utility model, a sanding belt baffle of the appropriate specification is replaced according to the determined grinding surface area. The replaced sanding belt baffle must be precisely aligned and installed to ensure that when the object to be ground comes into contact with the sanding belt for grinding, the sanding belt baffle can stably abut against the non-working side of the sanding belt. This effectively limits the displacement of the sanding belt during the grinding process, preventing the grinding trajectory from deviating from the preset path due to sanding belt offset, thereby ensuring the stability of the grinding operation and the final surface finish of the workpiece.
