Detailed Description

The following description of the embodiments of the present utility model will be made in detail and with reference to the accompanying drawings, wherein it is apparent that the embodiments described are only some, but not all embodiments of the present utility model. All other embodiments, which can be made by a person of ordinary skill in the art without the need for inventive faculty, are within the scope of the utility model, based on the embodiments described in the present utility model.

The embodiment of the utility model provides a neodymium iron boron magnet grinding machine fixture, which is shown in fig. 1 to 5, and comprises a rotating shaft 1 and a clamping block 2, wherein the top of the rotating shaft 1 is fixedly connected with a gear clamping groove 8, two guide rails 3 are symmetrically distributed on the upper half part and the lower half part of the rotating shaft 1, and gear teeth are arranged in the middle of the rotating shaft and are in meshed connection with a rack 6. The clamping block 2 is divided into an upper part and a lower part, the clamping block 2 is slidably connected to the side face of the baffle 9, a sliding groove 11 is formed in the baffle 9, the inner side of the clamping block 2 is fixedly connected with the fixed rod 4, the fixed rod 4 passes through a guide groove 13 on the movable plate 5 to be slidably connected to the guide rail 3 on the surface of the rotating shaft 1, the inner side of the movable plate 5 is fixedly connected with the rack 6, the rack 6 is fixedly supported by the limiting block 7 and the limiting groove 12, and the tooth face is meshed and connected with the middle part of the rotating shaft 1.

In the use process of the utility model, the magnet feeding is pushed against the movable plate 5 to inwards push, when the movable plate 5 is forced to inwards slide, the rack 6 is driven to inwards slide, the rotating shaft 1 is driven to do autorotation motion by the meshing transmission of the teeth on the rack 6 and the teeth in the middle of the rotating shaft 1, when the rotating shaft 1 autorotates, the guide rail 3 drives the fixed rod 4 to move up and down, the clamping force is applied to the clamping block 2 through the fixed rod 4, and after the clamping, the bolt is inserted through the limiting hole 10 to clamp the gear clamping groove 8 to prevent translocation, so that the stable clamping of the magnet is realized.
