Description

Technical Field

[0001] The utility model relates to the technical field of production of NdFeB products, in particular to an auxiliary device for cutting columnar pieces used for production and cutting of NdFeB products. Background Art

[0002] In the process of producing NdFeB products, cylindrical NdFeB blanks are first manufactured, and then these cylindrical blanks are cut into pieces of NdFeB finished products using wire cutting technology. The cylindrical NdFeB blanks are glued to the marble slab with glue, and after cutting, the cut NdFeB flake products are put into sodium hydroxide solution for boiling to remove the glue on the NdFeB flake products.

[0003] The cutting effect of NdFeB products is affected by factors such as the quality of glue and the employees' bonding level, which can easily cause the cylindrical NdFeB blank to tilt or even fall during the cutting process. At the same time, the glue boiling process will damage the bonding force of the NdFeB product surface, which may cause the coating to fall off after electroplating.

[0004] A Chinese patent with application number 202020355140.1 discloses a NdFeB magnet cutting device, including a cutting fixing plate, a magnetic fixing seat, a position adjustment component and a fixing clamp. The cutting fixing plate is arranged in a plate shape, and the magnetic fixing seat is arranged on the upper surface of the cutting fixing plate. There are two groups of magnetic fixing seats, and the two groups of magnetic fixing seats are symmetrically arranged. There are two groups of position adjustment components, and the two groups of position adjustment components are symmetrically arranged on the opposite side walls of the two groups of magnetic fixing seats. There are two groups of fixing clamps, and the two groups of fixing clamps are respectively arranged on the movable ends of the position adjustment components.

[0005] The two ends of the NdFeB blank are clamped and fixed in a fixing clamp, and then the NdFeB blank is cut into sheets by wire cutting. Although the above scheme can be used for cutting NdFeB blanks of different sizes, it can only clamp and fix a small number or even only one NdFeB blank, so there is a problem of low production efficiency. Utility Model Content

[0006] The utility model aims to provide an auxiliary device for cutting a columnar piece which can clamp a plurality of workpieces at one time, thereby improving production efficiency.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an auxiliary device for cutting a columnar part, comprising a support plate for supporting a workpiece, the support plate being located in a shell, the shell comprising side plates located on the left and right sides of the support plate and an upper plate on the upper side, the lower end surface of the upper plate is parallel to the upper end surface of the support plate, the inner surfaces of the side plates on both sides are parallel to each other, the side plates and the upper plate are both provided with cutting avoidance grooves that penetrate left and right and penetrate upward, the cutting avoidance grooves of the side plates correspond to and are connected with the cutting avoidance grooves of the upper plate, the upper end surface of the support plate is provided with retreat grooves that penetrate left and right and correspond one-to-one to the cutting avoidance grooves, the shell is also provided with a fixing plate located on the lower side of the support plate, the fixing plate is threadedly matched with an adjusting column, and the support plate support is fixed to the upper end of the adjusting column.

[0009] The utility model can be used for clamping workpieces of different sizes to be cut, and the workpieces can be placed in a reasonable position. Since the outer edge of the workpiece is circular, when the support plate rises, the workpiece will move adaptively, so that workpieces of different diameters can be clamped. The distance between the support plate, the upper plate and the side plate of the utility model in the front-to-back direction should be greater than the axial distance of the workpiece. Among them, the width between the two side plates can be set according to the diameter of different types of cylindrical NdFeB blank workpieces, so that the width between the two side plates of the utility model is suitable for the side-by-side placement of most workpieces of different diameters, and the stacked workpieces can be laterally limited so that when the support plate rises, the workpiece does not shake left and right.

[0010] Among them, the part of the adjusting column located on the lower side of the supporting plate can cooperate with the wrench to rotate and lift the adjusting column by manual operation; the lower end of the adjusting column can also be linked with the output end of the linear drive. The linear telescopic drive can be a cylinder or a hydraulic cylinder, or it can be an electric push rod. The lower end of the adjusting column and the output end of the linear telescopic drive can be linked through a bearing or a universal joint.

[0011] The utility model can not only be used for clamping NdFeB blank workpieces to facilitate cutting of the NdFeB blank workpieces, but can also be used for clamping other columnar workpieces.

[0012] Preferably, the support plate is fixed with a plurality of guide columns extending downward, the guide columns are threaded with locking nuts, the locking nuts are located between the support plate and the fixed plate, and the fixed plate is provided with guide holes opening upward for the lower ends of the guide columns to extend into.

[0013] The guide column is provided to ensure the levelness of the upper end surface of the support plate and the stability of the workpiece after clamping.

[0015] The upper plate and the lower plate can be made of different materials, and the upper plate can be made of a more wear-resistant material. The upper plate and the lower plate can be fixed together by any existing detachable fixing method, so as to facilitate the replacement of the worn or damaged upper plate. Among them, the utility model provides an upper plate with a matching hole that can accommodate the upper end of the guide column, without the need to process a transverse through groove corresponding to the backing groove on the upper end of the guide column, and at the same time facilitates the fixation between the guide column and the support plate.
