At present, the production of rotary files mainly involves injecting metal powder into ordinary molds for molding and sintering into file head blanks. The file head blanks are then ground to form the file heads. During processing, the file head blanks need to be fixed to ensure the processing accuracy of the file head blanks.

[0003] In response, Chinese patent application number CN202021102419.5 discloses a grinding device for machining high-speed steel rotary files. The device includes a machining platform and multiple support legs mounted on the lower end of the platform. Positioning boxes and a movable frame are respectively located on both sides of the upper end of the machining platform. A positioning mechanism is installed on the side of the positioning box closest to the movable frame. A grinding mechanism is installed on the upper part of the side wall of the movable frame. A displacement mechanism is installed at the lower end of the movable frame through a strip-shaped sliding hole opened in the side wall of the machining platform. The positioning mechanism includes a rear support block inserted into the side wall of the positioning box. This utility model is particularly suitable for grinding high-speed steel rotary files and has high social use value and application prospects.

[0004] This device can clamp and fix a rotary file blank by setting a clamping positioning block and a positioning cylinder. However, in the actual processing, rotary file blanks with different shaft diameters are often encountered. The inner wall curvature of the clamping positioning block is fixed, which cannot be used to fix rotary file blanks with different shaft diameters. This makes the device quite limited in use and will affect the user experience.

[0005] Therefore, in order to solve the above problems, a precision positioning alloy rotary file chuck is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a precision positioning alloy rotary file chuck to solve the problem mentioned in the background art. The prior art device can clamp and fix the rotary file blank by setting a clamping positioning block and a positioning cylinder. However, in the actual processing, rotary file blanks with different shaft diameters are often encountered. The inner wall curvature of the clamping positioning block is fixed, which cannot be used to fix rotary file blanks with different shaft diameters. This makes the device have obvious limitations in use and affects the user experience.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a precision positioning alloy rotary file chuck, comprising: a processing table, a cylinder mounted on the top surface of the processing table, and a grinding mechanism mounted on the extended end of the cylinder;

[0008] A positioning structure is installed on the processing table. The positioning structure includes a positioning plate, which is fixedly installed on the top surface of the processing table. A positioning cylinder is fixedly connected to the right side wall of the positioning plate. A positioning groove is opened on the right side wall of the positioning cylinder. Fixed frames are fixedly connected to the upper and lower sides of the positioning cylinder. A movable plate is slidably installed at the end of the fixed frame. An inclined groove is opened on the surface of the movable plate. A spring is fixedly connected to the surface of the movable plate. Magnetic blocks are glued to the mating surfaces of the two sets of movable plates.

[0009] A fixing structure is installed on the right side of the positioning structure. The fixing structure includes a mounting frame, which is fixedly installed on the top surface of the processing table. Two sets of electric push rods are fixedly installed at the front end of the mounting frame, and the extended ends of the electric push rods are fixedly connected to grippers.

[0010] Preferably, the inclined grooves on the two sets of movable plates form a "V" shape, and the mating surfaces of the two sets of movable plates coincide with the axis of the positioning groove.

[0011] Preferably, one end of the spring is fixedly connected to the fixing frame.

[0012] Preferably, the two sets of magnetic blocks are magnetically attracted to each other.

[0013] Preferably, the grippers are L-shaped, the two sets of grippers are adapted to each other, and are located on the upper and lower sides of the extended section of the positioning groove axis.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting two sets of mutually compatible grippers, and the two sets of grippers are in an "L" shape, the two sets of grippers can be inserted into each other during use, which can fix rotating file blanks with different shaft diameters, thus expanding the applicability of the device and improving its practicality.

[0015] 1. This utility model has a positioning structure that holds a rotating file blank and inserts it between two sets of movable plates. The rotating file blank pushes the inclined groove, causing the movable plates to slide at the end of the fixed frame. The two sets of movable plates then move away from each other, and the rotating file blank passes through the magnetic block and is inserted into the positioning groove of the corresponding size. The end of the positioning groove can be installed in the positioning cylinder, and the magnetic block can magnetically fix the rotating file blank, keeping the rotating file blank horizontal and preventing it from falling off.

[0016] 2. This utility model features a fixed structure. When the electric push rod is activated, it drives the grippers to move. The two sets of grippers then move closer to the rotating file blank and interlock, fixing the rotating file blank between them. This ensures the rotating file blank is stably fixed. Because the two sets of grippers have an "L" shape, they can fix rotating file blanks with different shaft diameters after interlocking, expanding the applicability of the device and improving its practicality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 The present invention provides an embodiment of a precision positioning alloy rotary file chuck:

[0024] The processing table 1, cylinder 11, grinding mechanism 12 and electric push rod 32 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0025] A precision positioning alloy rotary file chuck includes: a processing table 1, a cylinder 11 mounted on the top surface of the processing table 1, and a grinding mechanism 12 mounted on the extended end of the cylinder 11.

[0026] A positioning structure 2 is installed on the processing table 1. The positioning structure 2 includes a positioning plate 21, which is fixedly installed on the top surface of the processing table 1. A positioning cylinder 22 is fixedly connected to the right side wall of the positioning plate 21. A positioning groove 23 is provided on the right side wall of the positioning cylinder 22. A fixing frame 24 is fixedly connected to the upper and lower sides of the positioning cylinder 22. A movable plate 25 is slidably installed at the end of the fixing frame 24. An inclined groove 26 is provided on the surface of the movable plate 25. A spring 27 is fixedly connected to the surface of the movable plate 25. A magnetic block 28 is glued to the mating surface of the two sets of movable plates 25.

[0027] A fixing structure 3 is installed on the right side of the positioning structure 2. The fixing structure 3 includes a mounting frame 31, which is fixedly installed on the top surface of the processing table 1. Two sets of electric push rods 32 are fixedly installed at the front end of the mounting frame 31. The extended ends of the electric push rods 32 are fixedly connected to grippers 33. The two sets of grippers 33 are mutually compatible and have an "L" shape. In use, the two sets of grippers 33 can be inserted into each other, which can fix rotating file blanks with different shaft diameters, expand the application range of the device and improve its practicality.

[0028] Furthermore, the inclined grooves 26 on the two sets of movable plates 25 form a "V" shape, and the mating surfaces of the two sets of movable plates 25 coincide with the axis of the positioning groove 23. When the rotating file blank abuts against the inclined groove 26, it can push the two sets of movable plates 25 to move.

[0029] Furthermore, one end of the spring 27 is fixedly connected to the fixed frame 24, and the spring 27 provides power for the movable plate 25 to clamp the rotating file blank, so that the rotating file blank remains horizontal.

[0030] Furthermore, the two sets of magnetic blocks 28 are magnetically attracted to each other, and the magnetic blocks 28 can magnetically fix the rotating file blank to prevent the rotating file blank from falling off.

[0031] Furthermore, the grippers 33 have an "L" shaped structure, with two sets of grippers 33 adapted to each other and located on the upper and lower sides of the extended section of the positioning groove 23 axis. After the two sets of grippers 33 are inserted into each other, they can clamp and fix the rotating file blank in the positioning groove 23.

[0032] Working principle: Before processing, the rotary file blank can be held and inserted between the two sets of movable plates 25. The rotary file blank will push the inclined groove 26, so that the movable plate 25 slides at the end of the fixed frame 24. The two sets of movable plates 25 will then move away from each other, and the rotary file blank will pass through the magnetic block 28 and be inserted into the positioning groove 23 of the corresponding size. The end of the positioning groove 23 can be installed in the positioning cylinder 22, and the magnetic block 28 can magnetically fix the rotary file blank, so that the rotary file blank is kept horizontal and prevents the rotary file blank from falling off.

[0033] When the electric push rod 32 is activated, it drives the grippers 33 to move. The two sets of grippers 33 then move closer to the rotating file blank and interlock with each other, fixing the rotating file blank between them. This ensures the rotating file blank is stably fixed. Since the two sets of grippers 33 have an "L"-shaped structure, they can fix rotating file blanks with different shaft diameters after interlocking, expanding the applicability of the device and improving its practicality.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
