Description

Technical Field

[0001] This utility model belongs to the field of positioning tooling technology, and specifically relates to a positioning tooling for motor core laminations. Background Technology

[0002] The positioning fixture for motor core laminations is a key piece of equipment used for precise positioning of core laminations during motor manufacturing. Its design aims to ensure that the laminations maintain a precise position and relative angle throughout the stacking and assembly processes, thereby guaranteeing the manufacturing accuracy and performance stability of the motor core.

[0003] When iron core laminations are stacked, the direction of pressure may rotate, resulting in uneven wire grooves in the stacked laminations, which increases the difficulty of winding. To address this issue, we propose a positioning fixture for motor iron core laminations. Utility Model Content

[0004] This utility model proposes a positioning fixture for motor core laminations, which solves the problems in the prior art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A positioning fixture for a motor core lamination includes upper and lower pressure plates and a base plate. A positioning component is fixedly arranged at the center of the upper end of the base plate, and a lamination body is sleeved on the outer periphery of the positioning component.

[0007] The positioning component includes a positioning post and a positioning block arranged around the periphery of the positioning post. The inner periphery of the stamp body is also provided with a through groove. When the stamp body is fitted into the positioning post, the two ends of the positioning block are engaged with the inner walls on both sides of the through groove.

[0008] The positioning block moves along the inside of the positioning post, and an adjusting bolt is in contact with one end face of the positioning block near the positioning post.

[0009] Furthermore, a cavity is provided inside the positioning column, and the adjusting bolt passes through the cavity and abuts against the end face of the positioning block.

[0010] Furthermore, a groove is provided on the outer side of the positioning column, and the end of the adjusting bolt away from the positioning block is located in the groove.

[0011] Furthermore, at least two sets of positioning blocks are provided, and the number of adjusting bolts is the same as the number of positioning blocks.

[0012] Furthermore, the adjusting bolts are staggered vertically.

[0013] Furthermore, a positioning component is fixedly provided on the inner side of the pressure plate, and positioning pins are fixedly installed on the upper surface of the base plate around the positioning component. The pressure plate and the base plate are positioned against each other by the insertion of the positioning component and the positioning pin.

[0014] Furthermore, a groove is also provided on the outer side of the stamping body.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] In this invention, by providing movable positioning blocks, the two ends of the positioning blocks can always be locked on the inner walls of both sides of the through groove, achieving point-to-point contact. This effectively prevents the stamping body from rotating during the stacking process, thus preventing the wire groove of the stamping body from becoming uneven and facilitating subsequent winding.

Detailed Implementation

[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] Example:

[0025] like Figure 1As shown, a positioning fixture for a motor core lamination includes a pressure plate 10 and a base plate 20 arranged at the top and bottom. A positioning component 30 is also fixedly arranged at the center of the base plate 20. A lamination body 40 is also sleeved on the outer edge of the positioning component 30. The lamination body 40 is sleeved along the positioning component 30.

[0026] like Figure 2 As shown, the positioning assembly 30 includes a positioning post 301, wherein the lamination body 40 is positioned on the outside of the positioning post 301. To prevent the lamination body 401 from rotating selectively during the stacking of the pressure plate 10, as shown... Figure 3 As shown, two sets of positioning blocks 303 are also provided around the positioning post 301. The stamping body 401 and the positioning block 303 are respectively provided with through grooves 42. The two ends of the positioning block 303 are stuck on the inner walls of the two sides of the through groove 42, making point-to-point contact to position the stamping body 40. This can effectively prevent the stamping body 40 from rotating during stacking. A wire groove 41 is provided at the outer edge of the stamping body 40 for winding. If the stamping body 40 does not rotate during stacking, the wire groove 41 will be in a neat state after stacking, which is beneficial to the subsequent winding process.

[0027] like Figure 4 As shown, in order to better position the lamination body 40, the positioning block 303 is designed to move along the inner side of the positioning post 301. Specifically, an adjusting bolt 305 is provided on the end face of the positioning block 303 near the positioning post 301. By turning the adjusting bolt 305, the positioning block 303 can move in the A or B direction to adapt to the width of the through groove 42, ensuring that the positioning block 303 is always in point-to-point contact with the through groove 42, which facilitates the removal of the stacked laminations later. When the adjusting bolt 305 is turned, a cavity 302 is also provided inside the positioning post 301. A groove 304 is also provided on the side wall of the positioning post 301 and at the bolt head of the adjusting bolt 305. The adjusting bolt 305 passes through the cavity 302, with one end contacting the end face of the positioning block 303 and the other end located in the groove 304. The user can easily turn the bolt head of the adjusting bolt 305 in the groove 304. The adjusting bolt 305 is divided into two groups and is staggered vertically to avoid positional conflicts during adjustment.

[0028] In addition, such as Figure 1 As shown, positioning elements 11 are provided on the inner sides of the four corners of the pressure plate 10, and positioning pins 21 are fixedly provided on the upper surfaces of the four corners of the base plate 20 in correspondence with the positioning elements 11, so that the positioning elements 11 on the pressure plate 10 can be inserted along the positioning pins 21.

[0029] Working principle: During use, first, a set of stamping bodies 40 are inserted into the tooling along the positioning post 301. The through groove 42 on the stamping body 40 is lowered along the two sets of positioning blocks 303. The adjusting bolt 305 is turned to push the positioning blocks 303 forward. The two ends of the positioning blocks 303 abut against the inner walls of the two sides of the through groove 42 to position the stamping body 40. Then, the remaining sets of stamping bodies 40 are inserted into the positioning post 301 in sequence. Finally, the positioning piece 11 on the pressure plate 10 is placed on the upper end face of the uppermost stamping body 40 along the positioning pin 21 to complete the positioning of the stamping.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
