Description

Technical Field

[0001] This utility model relates to the field of stator core processing technology, specifically a stator core pressing ring tool for CNC lathes. Background Technology

[0002] In the production and processing of stator cores, the stator core retaining ring is a key component, and the accuracy of its outer edge directly affects the assembly quality and performance of the stator. Due to the burrs, warping, and other defects that are easily generated on the outer edge of the retaining ring blank during the early processing stages such as cutting, stamping, and stretching, it is necessary to perform fine grinding and finishing on a CNC lathe.

[0003] According to the publication number (CN222588149U), a CNC lathe stator core pressing ring tooling is disclosed, which includes several chuck blocks. The chuck blocks are arc-shaped and can be spliced ​​together to form a complete circle. The arc edge of the chuck block is provided with a placement groove for clamping and placing the stator core pressing ring blank. The placement groove and the chuck block are stepped. A pressing plate is provided on one side of the chuck block to clamp and fix the stator core pressing ring blank in conjunction with the placement groove.

[0004] However, existing positioning fixtures for stator core pressing ring blanks have significant shortcomings in the current machining process: traditional positioning methods rely heavily on bolts for point-to-point fixing, which is cumbersome and time-consuming, and prone to blank displacement due to uneven force, affecting grinding accuracy; at the same time, the connection stability between the fixture and the lathe is insufficient, and the position may loosen due to vibration during machining, further reducing the product qualification rate and increasing rework costs, which urgently needs improvement. Therefore, we propose a stator core pressing ring machining fixture for CNC lathes. Utility Model Content

[0005] The purpose of this utility model is to provide a stator core pressing ring tooling for CNC lathes, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stator core pressing ring tooling for a CNC lathe, comprising a positioning frame, a lathe mounting seat on one side of the positioning frame, a stator core pressing ring blank on the outer side of the positioning frame, a positioning component for positioning the stator core pressing ring blank in the middle of the inner cavity of the positioning frame, and a limiting component for limiting the positioning frame on one side of the positioning component.

[0007] Optionally, the positioning component includes a fixed rod disposed in the middle of the positioning frame, a support frame welded to the front end of the positioning frame, arc-shaped plates welded to both sides of the fixed rod, straight rods movably mounted on both sides of the positioning frame, a positioning frame fixedly mounted on the outer end of the straight rod, and a rubber pad adhered to the inner side of the positioning frame.

[0008] Optionally, the limiting component includes a positioning gear disposed at the front end of the fixed rod, the lathe mounting seat is disposed on one side of the positioning gear, the inner cavity of the lathe mounting seat is provided with a positioning tooth groove, the size of the positioning gear is adapted to the size of the positioning tooth groove, and the positioning gear meshes with the positioning tooth groove.

[0009] Optionally, a return spring is sleeved on the outer side of the straight rod, and the other end of the return spring is fixedly connected to the inner cavity of the positioning frame.

[0010] Optionally, the inner diameter of the stator core pressing ring blank is larger than the outer diameter of the positioning frame.

[0011] Optionally, one end of the fixing rod passes through the middle of the support frame, and the fixing rod is movably connected to the support frame.

[0012] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0013] The technical solution of this application, through the setting of a positioning frame, stator core pressing ring blank, lathe mounting base, arc plate, straight rod, positioning frame, return spring, and positioning tooth groove, allows the fixed rod to drive the arc plate to rotate, so that the arc plate simultaneously pushes the two straight rods. The arc plate drives the straight rods to move outward, while compressing the return spring, causing the straight rods to drive the positioning frame to abut against the inner wall of the stator core pressing ring blank, thereby pressing and limiting the stator core pressing ring blank. Furthermore, the setting of rubber pads further enhances the contact between the positioning frame and the stator core pressing ring blank. The frictional force of contact ensures the limiting effect on the stator core ring blank, eliminating the trouble of gradually limiting it with bolts, thus improving the grinding effect of the stator core ring blank. At the same time as limiting the stator core ring blank, the positioning gear on the fixing rod is inserted into the positioning groove on the lathe mounting seat. The meshing of the positioning gear and the positioning groove limits the positioning frame and the fixing rod, thus ensuring the positioning stability of the stator core ring blank.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a CNC lathe stator core pressing ring tooling, including a positioning frame 1, a lathe mounting seat 12 on one side of the positioning frame 1, a stator core pressing ring blank 11 on the outer side of the positioning frame 1, a positioning component for positioning the stator core pressing ring blank 11 in the middle of the inner cavity of the positioning frame 1, and a limiting component for limiting the positioning frame 1 on one side of the positioning component.

[0020] In this embodiment, during positioning, the stator core pressing ring blank 11 is first placed on the outside of the positioning frame 1, and then the positioning component is controlled to rotate, so that the positioning component can quickly limit the stator core pressing ring blank 11, eliminating the trouble of using bolts for gradual limitation, thereby improving the grinding effect of the stator core pressing ring blank 11. At the same time, the positioning component and the positioning frame 1 can be limited by the limiting component.

[0021] In this technical solution, the positioning component includes a fixed rod 2 located in the middle of the positioning frame 1, a support frame 25 welded to the front end of the positioning frame 1, arc-shaped plates 21 welded to both sides of the fixed rod 2, straight rods 22 movably installed on both sides of the positioning frame 1, a positioning frame 23 fixedly installed at the outer end of the straight rod 22, and a rubber pad 24 glued to the inner side of the positioning frame 23.

[0022] In this embodiment, during positioning, the stator core pressing ring blank 11 is first placed on the outside of the positioning frame 1. Then, the fixing rod 2 is rotated, and the fixing rod 2 drives the arc plate 21 to rotate as well. The arc plate 21 pushes the two straight rods 22 simultaneously, and the arc plate 21 drives the straight rods 22 to move outward. At the same time, the return spring 26 is compressed, so that the straight rods 22 drive the positioning frame 23 to abut against the inner wall of the stator core pressing ring blank 11, thereby pressing and limiting the stator core pressing ring blank 11. Furthermore, the rubber pad 24 is set to increase the friction between the positioning frame 23 and the stator core pressing ring blank 11, thereby ensuring the limiting effect of the stator core pressing ring blank 11. This eliminates the trouble of workers using bolts to gradually limit the material, and thus improves the grinding effect of the stator core pressing ring blank 11.

[0023] In this technical solution, the limiting component includes a positioning gear 3 disposed at the front end of the fixed rod 2, a lathe mounting base 12 disposed on one side of the positioning gear 3, and a positioning tooth groove 4 opened in the middle of the inner cavity of the lathe mounting base 12. The size of the positioning gear 3 is adapted to the size of the positioning tooth groove 4, and the positioning gear 3 meshes with the positioning tooth groove 4.

[0024] In this embodiment, while the stator core pressing ring blank 11 is positioned, the positioning gear 3 on the fixing rod 2 is inserted into the positioning groove 4 on the lathe mounting seat 12. The meshing of the positioning gear 3 and the positioning groove 4 limits the positioning frame 1 and the fixing rod 2, thereby ensuring the positioning stability of the stator core pressing ring blank 11.

[0025] In this technical solution, a return spring 26 is sleeved on the outer side of the straight rod 22, and the other end of the return spring 26 is fixedly connected to the inner cavity of the positioning frame 1.

[0026] In this embodiment, the reset spring 26 can drive the straight rod 22 to reset, thereby facilitating the removal of the processed stator core ring blank 11.

[0027] In this technical solution, the inner diameter of the stator core pressing ring blank 11 is larger than the outer diameter of the positioning frame 1.

[0028] In this embodiment, it is convenient to place the stator core pressing ring blank 11 on the outside of the positioning frame 1, thereby facilitating the positioning of the stator core pressing ring blank 11.

[0029] In this technical solution, one end of the fixing rod 2 passes through the middle of the support frame 25, and the fixing rod 2 is movably connected to the support frame 25.

[0030] In this embodiment, the stability of the rotation of the fixed rod 2 is ensured by setting the support frame 25.

[0031] During positioning, the stator core pressing ring blank 11 is first placed on the outside of the positioning frame 1. Then, the fixing rod 2 is rotated, causing the arc plate 21 to rotate as well. This causes the arc plate 21 to simultaneously push the two straight rods 22, moving them outwards. Simultaneously, the arc plate 21 compresses the return spring 26, causing the straight rods 22 to press against the inner wall of the positioning frame 23 against the stator core pressing ring blank 11. This provides pressure and constraint to the stator core pressing ring blank 11. Furthermore, the rubber pad 24 enhances the contact between the positioning frame 23 and the stator core pressing ring blank 11. Friction ensures the effective restraint of the stator core pressing ring blank 11, eliminating the need for workers to use bolts for gradual restraint. This improves the grinding effect of the stator core pressing ring blank 11. While the stator core pressing ring blank 11 is in position, the positioning gear 3 on the fixing rod 2 is inserted into the positioning groove 4 on the lathe mounting seat 12. The meshing of the positioning gear 3 and the positioning groove 4 further restrains the positioning frame 1 and the fixing rod 2, thus ensuring the positioning stability of the stator core pressing ring blank 11.
