Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically to a motor positioning tooling structure. Background Technology

[0002] In the motor manufacturing industry, the rotor, as the core component of the motor, directly affects the motor's performance and lifespan due to its machining accuracy and quality. Before machining the rotor, tooling structures are typically used to position and fix it to ensure the accuracy and stability of the machining process. However, traditional motor positioning tooling structures often suffer from problems such as limited positioning methods, poor adaptability, and unstable fixing, making it difficult to meet the positioning requirements of different types and specifications of rotors.

[0003] Specifically, traditional tooling structures typically use fixed clamps or slots to position the rotor. This method not only limits the rotor's placement angle and position but also makes it difficult to adapt to rotors of different sizes and shapes. In addition, the fixing methods of traditional tooling structures often have shortcomings, such as insufficient clamping force and easy loosening, which can cause the rotor to shift or wobble during processing, affecting machining accuracy and workpiece quality. Utility Model Content

The bottom surface of the locking block is also provided with at least two protruding rods that are inserted into the rotating seat. The top of the locking block is provided with a knob that is inserted and locked to the rotating seat.

[0009] Furthermore, the base plate surface is provided with at least two linear guide rails, which are connected to the uprights of the movable positioning component.

[0010] Furthermore, the top of the upright is provided with a central shaft that protrudes into the rotating seat, the central shaft is coaxially arranged with the rotating seat, and a retaining ring with a protrusion on the outside is embedded in the rotating seat.

[0023] 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.

[0024] like Figure 1-5 As shown, this utility model provides a motor positioning fixture structure, mainly used for fixing the internal rotor of a motor during machining. Its specific structure mainly includes a base plate 1 and two positioning components 2 disposed on its surface. The two positioning components 2 are symmetrically arranged and used to fix both ends of the rotor. To accommodate rotors of different lengths, one of the positioning components 2 is movable, allowing the user to adjust its position to suit rotors of varying lengths.

[0025] To facilitate adjustment of one of the movable positioning components 2, two parallel linear guide rails 3 are provided on the surface of the base plate 1. The two linear guide rails 3 are embedded inside the base plate 1 and are movably connected to the positioning component 2. At this time, the positioning component 2 can move towards the other fixed positioning component 2 or move in the opposite direction with the help of the linear guide rails 3.

[0026] The two positioning components 2 connected to the base plate 1 are symmetrically distributed and have the same structure. Structurally, the positioning component 2 consists of three parts: a vertical rod 201, a rotating seat 202, and a locking block 203. The rotating seat 202 is connected to the top of the vertical rod 201 and can rotate horizontally at multiple angles. The locking block 203 covers the top of the rotating seat 202, is fixed, and is a detachable structure.

[0027] When the upright 201 is connected to the rotating seat 202, a central shaft 208 with a protrusion inserted into the rotating seat 202 is provided at the top of the upright 201. The central shaft 208 is coaxially arranged with the rotating seat 202, and a retaining ring 209 with a protrusion embedded in the rotating seat 202 is provided on the outside. At this time, the rotating seat 202 can be horizontally rotated to different angles at the top of the upright 201.

[0028] To fix the rotor's position, three or more V-grooves 204 are provided on the top surface of the rotating seats 202 on both sides to rotate and fix the two ends of the rotor's rotating shaft. One end of each V-groove 204 is open to the side of the rotating seat 202 for easy rotor placement, and the multiple V-grooves 204 are distributed in a ring around the center of the rotating seat 202 surface. The rotating seats 202 on both sides can be adjusted to the same position of the V-grooves 204 to place the rotor. The V-groove structure of the rotor placement grooves better secures the rotor and prevents it from rolling within the V-grooves 204, affecting processing.

[0029] After the rotor is placed, it is locked and fixed by the locking block 203 above the rotating base 202. The bottom surface of the locking block 203 has a soft rubber layer 205 that fits against the top surface of the rotating base 202. The rotor's position is fixed by the pressure generated when the soft rubber layer 205 contacts the rotating base 202. When the locking block 203 is connected, a plug rod 206 is provided at the bottom to facilitate sliding insertion. The plug rod 206 can determine the locking position of the locking block 203. Finally, it is locked by the knob 207 inserted at the top of the locking block 203. At this time, the inserted plug rod 206 and the annularly distributed V-shaped grooves 204 are staggered to improve the stability of the connection.

[0030] In addition, the locking block 203 has a screw hole 210 for inserting the knob 207 in the middle, and the rotating seat 202 has a screw groove 211 for inserting and locking the knob 207 in the middle. At this time, the knob 207 is screwed in from one end of the screw hole 210 by twisting, and finally reaches the screw groove 211 to lock.

[0031] Compared with traditional technology, this technical solution uses two adjustable positioning components 2 to clamp and fix the rotor before processing. The rotating seat 202 of the positioning component 2 can be twisted, and a V-groove 204 suitable for rotor placement can be selected. It is then locked and fixed by locking block 203, which effectively improves the stability of the rotor before processing.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
