Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to marking positioning structures, in particular to a positioning structure for marking a stator core monomer. Background Art
[0002] Laser marking refers to a marking method that uses high-energy-density lasers to partially irradiate the stator, causing the stator surface material to vaporize or undergo a chemical reaction that changes color, thereby leaving a permanent code mark. When marking the stator core, it is required to uniformly print the date and code at a fixed position on the product.
[0003] In the prior art, the stator core needs to be fixed in position during marking, and the stator core is often clamped on the inner hole side wall at the center of the stator core by means of a clamping jaw to generate outward tension, so as to solve the problem that the stator core is easily misplaced. However, since the position of the stator core is only fixed by the friction between the inner hole side wall and the surface of the clamping jaw, on the one hand, the side wall of the clamping jaw is severely worn after long-term use or when fixing a stator core of larger specifications. On the other hand, when a stator core of larger specifications needs to be fixed, the friction generated is limited due to the insufficient contact area between the abutment plate and the inner hole side wall of the stator core, resulting in unstable fixation of the stator core.

Since the clamping block is elastically connected to the side wall of the center column, when working, the stator core is inserted into the annular area formed by a plurality of clamping blocks, and the clamping block is tightly fitted with the inner wall of the stator core under the elastic action, and then the support block is moved up until it is in contact with and fixed to the end face of the stator core by adjusting the height adjustment seat in the up and down directions.

The structure is simple, which is conducive to cost saving and convenient and quick operation. The two guide grooves are 360° rotationally symmetrical with the through hole as the center, which makes it easy for the support block to always maintain horizontal balance during the displacement adjustment process, which is beneficial for the stator core to maintain position stability and improve the marking accuracy.
[0009] Preferably, the bottom of the abutment column is fixedly connected to the adjustment block, and the top of the abutment column is spherical and contacts the bottom of the guide groove after passing through the open end of the guide groove. The shape design of the top of the abutment column is conducive to reducing friction when rotating the adjustment block to adjust the height of the support block, saving time and effort in operation.
[0010] Preferably, the circular base is provided with a plurality of T-shaped slots respectively matching with a plurality of support blocks, and the plurality of T-shaped slots are evenly distributed on the top of the circular base in a radial shape with the central column as the center, and the bottom of the support block is provided with a T-shaped slider matching with the corresponding T-shaped slot, and the support block is slidably connected to the circular base through the T-shaped slider at the bottom thereof matching with the corresponding T-shaped slot.

The guiding inclined surface plays a good guiding role in the insertion of the stator core; the connecting column matches the sliding groove on the clamping block, which is convenient for adjusting the height of the support block according to the specifications of the stator core. At the same time, the design of the stopper and the limiter is conducive to preventing the connecting column from being separated from the sliding groove, thereby ensuring the stability of the structure.
[0013] Preferably, two elastic telescopic shafts are provided on the side walls at both ends of the clamping block, one end of the elastic telescopic shaft is fixedly connected to the side wall of the clamping block, and the other end of the elastic telescopic shaft is fixedly connected to the side wall of the center column.

The top of the adjusting block is rotated in the corresponding guide groove through the abutment column to realize the displacement adjustment of the support block in the height direction. At the same time, the bottom of the adjusting block is located on the turntable, which is conducive to ensuring the support strength of the support block, facilitating the practical use of more large-sized stator cores, and improving practicality. During operation, the worker sits in front of the operating table and inserts the waiting stator core on the fixture. The inner hole in the middle of the stator core contacts the guide inclined surface. As the stator core is continuously pressed down, the clamping block overcomes the elastic effect of the elastic telescopic shaft and gradually approaches the central column. Finally, under the action of the elastic telescopic shaft, it abuts against the side wall of the inner hole of the stator core to limit the stator core. Then, the adjusting block is rotated to adjust the height of the support block until the support block contacts the bottom of the stator core, thereby supporting it. The motor drives the turntable to rotate a certain angle, and the stator core to be marked is turned under the marking machine for marking. At the same time, the stator core that has been marked is turned out, which is convenient for workers to disassemble and reinstall the stator core to be marked, which is conducive to improving work efficiency.

In the initial state, the pull rope is in a loose state. When the marked stator core needs to be removed, the worker only needs to rotate the tightening assembly through the bottom of the turntable, so that the pull rope is gradually wound around the tightening assembly and drives the clamp block to gradually approach the center column, which is convenient and quick to operate; due to the limited internal space of the center column, the rectangular hole is convenient for the pull rope to prevent the pull rope from piling up in one place when tightening, causing the tightening assembly to be unable to continue rotating.
