[0024] The following will be combined with the drawings in 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.

[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] With the gradual improvement of the domestic industrial production level, the quality requirements for the polishing of some parts are also becoming more and more stringent, from the earlier roughness requirement of Ra0.8 to the current Ra0.02 or less, which has prompted the emergence of some small polishing equipment. In the past, most polishing machines used electromagnetic coils to energize and generate relative resistance with the brake disc. The electromagnetic suction force was changed by adjusting the resistance of the potentiometer to achieve the purpose of braking.

[0027] This technology is not easy to control accurately during the operation of the equipment, and the braking resistance and the potentiometer adjustment cannot reach a linear relationship. Therefore, the braking resistance is either too large, causing the sanding belt to break; or the braking resistance is too small, causing the tension of the sanding belt to be too small during operation, seriously affecting the polishing effect, affecting work efficiency and greatly increasing production costs.

[0028] Therefore, please refer to Figure 1-Figure 5 As shown, this embodiment provides a brake device for a vibration polishing machine, including a connector 1 and a brake 2 arranged on the connector 1;

[0029] The brake 2 includes a pair of contact bodies 21 and an adjusting body 22 arranged on the top of the contact body 21. The bottom of the contact body 21 is rotatably connected to the connector 1. The contact body 21 is used to contact the vibration polishing machine for braking. The adjusting body 22 is used to adjust the distance between the two contact bodies 21 to adjust the braking resistance of the contact body 21. When in use, the distance between the two contact bodies 21 is changed by rotating the adjusting body 22, so that the brake pad 212 contacts the vibration polishing machine and adjusts the braking resistance to the vibration polishing machine. This brake device is centrally symmetrical and changes the braking mode by tightening or loosening in both directions. The braking purpose can be achieved by mechanically adjusting the tightness of the bolt. The braking resistance is accurately controlled and easy to operate, so that the sanding machine does not need to be adjusted for a period of time, which greatly saves the adjustment time of the polishing machine and achieves a good polishing effect.

[0030] In order to be able to contact the vibration polisher to provide resistance and achieve a braking effect, the connector 1 includes a brake base 11, a connecting groove 111 is provided on the top of the brake base 11, and the contact body 21 includes a brake brake 211 whose bottom is located in the connecting groove 111 and is rotatably connected to the connecting groove 111. A brake pad 212 for contacting the vibration polisher is provided on the inner wall of the brake brake 211. The brake pad 212 is fixedly contacted with the vibration polisher through the brake brake 211 to provide friction resistance and achieve braking of the vibration polisher. In addition, in order to facilitate the disassembly and replacement of the fixed shaft 213, the brake pad A fixed shaft 213 is provided on one side of the inner wall of the brake 211, and the fixed shaft 213 passes through the brake 211. The brake pad 212 is plugged and matched with the brake 211 through the fixed shaft 213. The plug-in matching method allows the brake pad 212 to be replaced after being worn, thereby ensuring the braking effect. Furthermore, a heat dissipation fin 214 for dissipating heat is provided on the outer wall of the brake 211. The heat generated by the friction of the fixed shaft 213 is dissipated to the outside through the brake 211 and then through the heat dissipation fin 214, thereby avoiding the influence of the braking effect due to overheating.

[0031] In order to keep the two brake pads 212 in contact with the vibration polisher, the adjusting body 22 includes a brake resistance adjusting bolt 221 connected to the top of the two brake holding brakes 211, and the two brake holding brakes 211 are fixed by the brake resistance adjusting bolt 221 cooperating with the holding brake base 11, thereby ensuring the contact of the two brake pads 212 with the vibration polisher. Secondly, in order to facilitate the adjustment of the distance between the two contact bodies 21 to adjust the tightness, a buckle groove 215 is provided on the top of the brake holding brake 211, and the adjusting body 22 also includes two buckle blocks 222, and the two ends of the buckle blocks 222 are rotatably connected to the inner wall of the buckle groove 215. The brake resistance adjusting bolt 221 passes through the buckle block 222 and is threadedly connected with a second nut, which is an M6 locking nut. The surface of the brake resistance adjusting bolt 221 is sleeved with a pressure spring 223, and the pressure spring 223 is connected to the surface of the buckle block 222. By tightening the brake resistance adjusting bolt 221, the distance between the two brake holding brakes 211 is reduced, and the friction resistance is increased. Otherwise, the friction resistance is reduced.

[0032] Furthermore, in order to facilitate the replacement of the brake brake 211, a connecting handle 216 is provided at the bottom of the brake brake 211, and the connecting handle 216 is located in the connecting groove 111. The surface of the brake base 11 is symmetrically rotated and connected with a brake mounting shaft 112. The brake mounting shaft 112 passes through the connecting handle 216 and is threadedly connected to a first nut 113. By setting a threaded connection, the brake mounting shaft 112 can be removed from the connecting handle 216 by disassembling the first nut 113, and then the brake brake 211 can be removed from the connecting groove 111, thereby facilitating the replacement of the brake brake 211.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
