Detailed implementation manners

[0023] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present utility model in combination with the embodiments and drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts all fall within the scope of protection of the present utility model. In addition, all the connection relationships mentioned in the text do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the present invention can be combined interactively without conflicting with each other.

[0024] Before grinding the side surface of the rod-shaped workpiece, it is necessary to first fix the rod-shaped workpiece. At present, for the clamping of the rod-shaped workpiece, generally a bench vice is used to directly clamp the rod-shaped workpiece, making the length direction of the rod-shaped workpiece parallel to the clamping length direction of the bench vice, and at the same time, it is also necessary to level the rod-shaped workpiece, and its operation is complex.

[0025] Another part will use two three-jaw chucks to clamp the two ends of a rod-shaped workpiece in order to grind the side of the middle part of the rod-shaped workpiece. However, the middle part of the rod-shaped workpiece lacks support, and during the grinding process, the workpiece is prone to bending deformation. It is necessary to use support pieces of different heights to support the middle part of the workpiece according to the diameter of the rod-shaped workpiece, and at the same time, it is necessary to avoid interference between the support piece and the grinding area, and its structure is relatively complex.

[0026] Therefore, the present utility model provides a grinding jig, as Figures 1 to 4 shown, which includes a mounting base 11 and a locking member; an installation channel is provided on the mounting base 11, and the installation channel is used to place a rod-shaped workpiece. A locking hole 110 is provided on the mounting base 11, and the locking hole 110 communicates with the installation channel. The locking member is arranged at the locking hole 110, and the locking member is used to press the rod-shaped workpiece so that the rod-shaped workpiece is closely attached to the inner wall of the installation channel. A grinding hole 15 is provided on the mounting base 11, and the grinding hole 15 communicates with the installation channel.

[0027] As can be seen from the above, the traditional bench vise clamping method requires complex manual leveling operations. In this technical solution, the rod-shaped workpiece is directly placed through the installation channel on the mounting base 11, and the workpiece is fixed by closely attaching it to the inner wall of the installation channel using the locking member, greatly simplifying the clamping process and improving work efficiency. Compared with the method of using two three-jaw chucks for clamping, the installation channel in this technical solution provides stable support for the rod-shaped workpiece, effectively avoiding the bending deformation of the workpiece during the grinding process due to the lack of middle support. In the traditional method, it is necessary to use support pieces of different heights according to the diameter of the workpiece, and it is necessary to avoid interference between the support piece and the grinding area, and the structure is complex. In this technical solution, the stable clamping of the workpiece can be achieved through a single mounting base 11 and a locking member, without the need for additional support pieces, the structure is simple, and the manufacturing cost is reduced. The design of the installation channel has a certain universality and can adapt to rod-shaped workpieces of different diameters. At the same time, the adjustability of the locking member also enhances the flexibility of clamping, making this technical solution applicable to rod-shaped workpieces of various specifications. Since the workpiece can be stably attached to the inner wall of the installation channel during the clamping process, the shaking and offset of the workpiece during the grinding process are reduced, thereby improving the grinding accuracy and quality. The design of the locking member makes the clamping and disassembling process of the workpiece more convenient and improves work efficiency. Through the setting of the grinding hole 15, it is convenient for an external grinding tool to pass through the grinding hole 15 to process the rod-shaped workpiece, and its use is convenient.

[0028] In order to facilitate the grinding of the workpiece mounted on the grinding jig, the grinding jig further includes a mounting table 12, a guide rail 13 fixed on the mounting table 12, and a slider 14 arranged on the guide rail 13, the slider 14 and the guide rail 13 can be relatively slidably matched and connected, and the mounting seat 11 is fixed on the slider 14. The structure is simple and convenient to set. The slider 14 is arranged on the guide rail 13, the mounting table 12 is fixedly connected to the slider 14, and the mounting table 12 can slide along the extension direction of the guide rail 13.

In some embodiments, the installation channel extends in the transverse direction, and the width of the installation channel gradually increases from bottom to top. Through the arrangement of this structure, cylindrical rod-shaped workpieces with different diameter specifications can still be supported by the two side walls of the installation channel. The rod-shaped workpiece is pressed downward by the locking member, and combined with the inner wall of the installation channel, the rod-shaped workpiece can be clamped from three directions to achieve the limitation of the workpiece.

[0032] When in use, the workpieces placed in different installation channels are workpieces of the same size.

[0033] The width of the installation channel increases gradually from bottom to top. To this end, in some embodiments, the installation channel includes a triangular channel 1111. The cross section of the triangular channel 1111 is an isosceles triangle, and the angle formed by the two waists of the isosceles triangle opens upward.
