The following describes in detail a tooling device on a motor stator provided in an embodiment of the present application through a specific embodiment and an application scenario thereof with reference to the accompanying drawings.
As shown in fig. 1 to 3, an embodiment of the present application provides an upper fixture device for a motor stator, which is used for clamping an outer core of the stator, and includes a mounting base 100, an annular turntable 200, a driving mechanism 300, an annular gland 400, and a clamping mechanism 500.
The mounting base 100 can provide a mounting base for other mechanisms of the tooling device on the motor stator so as to facilitate the mounting of other mechanisms.
The annular turntable 200 is rotatably disposed in the mounting base 100, the annular turntable 200 is provided with at least two first bar-shaped grooves 201, and the at least two first bar-shaped grooves 201 extend obliquely in a radial direction of the annular turntable 200 and are uniformly distributed on the annular turntable 200. That is, the extending directions of the at least two first linear grooves 201 are consistent and are uniformly distributed on the ring turntable 200.
The driving mechanism 300 is connected to the ring turntable 200. The drive mechanism 300 may be an adjustable stroke linear cylinder that is capable of reciprocating motion. The drive mechanism 300 may drive the annular turntable 200 to rotate within the mounting base 100.
The annular gland 400 is fixedly connected with the mounting base 100, the annular gland 400 is provided with at least two second strip-shaped grooves 401, and the at least two second strip-shaped grooves 401 extend in the radial direction of the annular gland 400 and are uniformly distributed in the annular gland 400. That is, the extending directions of the at least two second grooves 401 are the same and are uniformly distributed on the annular gland 400.
The number of the clamping mechanisms 500 is at least two, and the clamping mechanisms 500 can be simultaneously in sliding fit with the first strip-shaped groove 201 and the second strip-shaped groove 401. In other words, the clamping mechanism 500 is able to slide within the first and second bar- shaped slots 201, 401 simultaneously.
When the stator outer core is clamped, the driving mechanism 300 drives the annular turntable 200 to rotate, so that the clamping mechanism 500 moves in the radial direction of the annular turntable 200.
In this embodiment of the application, when the stator outer core needs to be clamped, the stator outer core can be placed between the clamping mechanisms 500, and then the driving mechanism 300 drives the annular turntable 200 to rotate, so as to drive the clamping mechanisms 500 to slide in the first bar-shaped grooves 201 and the second bar-shaped grooves 401, and the clamping mechanisms 500 move along the radial direction of the annular turntable 200, so as to clamp the stator outer core. Because first bar groove 201 sets up in annular carousel 200 evenly, second bar groove 401 sets up in annular gland 400 evenly to the effort that makes clamping mechanism 500 receive is comparatively even, is favorable to avoiding the axis of the outer core of stator and installing in assembly platform's interior iron core axis down to have the deviation, and then is favorable to promoting the quality of the stator core that the pressure equipment was come out.
In an embodiment, the tooling device for the stator of the motor may further include a connecting mechanism 600, and the driving mechanism 300 is rotatably connected to the annular turntable 200 through the connecting mechanism 600. In the case where the driving mechanism 300 drives the annular turntable 200 to rotate through the connection mechanism 600, the rotation connection easily causes the coaxial degree and the parallelism of the annular turntable 200 to be damaged, so that it is difficult to ensure the rotation accuracy of the annular turntable 200. Therefore, in another embodiment, the driving mechanism 300 is connected with the annular turntable 200 in a floating manner through the connecting mechanism 600. Under the condition that the driving mechanism 300 drives the annular turntable 200 to rotate through the connecting mechanism 600, the floating connection can ensure the coaxiality and the parallelism of the annular turntable 200 during rotation, thereby being beneficial to ensuring the rotation precision of the annular turntable 200. Optionally, the connection mechanism 600 is a joint bearing ball-head type joint.
In an alternative embodiment, in order to raise the limit of the clamping mechanism 500, the mounting base 100 is provided with at least two grooves 101, at least two grooves 101 are uniformly distributed on the mounting base 100, and the clamping mechanism 500 is in limit fit with the grooves 101. When the clamping mechanism 500 moves, the clamping mechanism 500 moves along a predetermined direction due to the limitation of the groove 101, that is, the groove 101 not only can be used for limiting the clamping mechanism 500, but also can provide guidance for the clamping mechanism 500.
When the clamping mechanism 500 is in sliding fit with the first bar-shaped groove 201 and the second bar-shaped groove 401, the contact area is large, which is not beneficial to the sliding of the clamping mechanism 500. Therefore, in another alternative embodiment, the tooling device on the motor stator may further include at least two positioning shafts 700, the positioning shafts 700 are connected to the clamping mechanism 500, and the positioning shafts 700 may be simultaneously in sliding fit with the first bar-shaped groove 201 and the second bar-shaped groove 401. The line contact of the clamping mechanism 500 with the first bar-shaped groove 201 and the second bar-shaped groove 401 can be realized through the positioning shaft 700, so that the contact surfaces of the clamping mechanism 500 with the first bar-shaped groove 201 and the second bar-shaped groove 401 are reduced, and the sliding of the clamping mechanism 500 is further facilitated.
In an alternative embodiment, the clamping mechanism 500 may include a connecting rod 510 and a first clamping block 520, the connecting rod 510 is connected to the positioning shaft 700, the first clamping block 520 is connected to the connecting rod 510, and the first clamping block 520 extends in a radial direction of the annular turntable 200. In this embodiment, the clamping mechanism 500 has fewer points of action on the stator outer core, and thus has a less effective clamping effect on the stator outer core. Therefore, in another embodiment, the clamping mechanism 500 may further include a second clamping block 530, the first clamping block 520 and the second clamping block 530 are connected to the connecting rod 510, and the first clamping block 520 and the second clamping block 530 extend in a radial direction of the ring turntable 200 and gradually move away from each other. In this embodiment, the clamping mechanism 500 has more points of application to the stator outer core, and thus has a better clamping effect on the stator outer core.
In one embodiment, the first clamping block 520 and the second clamping block 530 are both of a cylindrical structure, and in the case that the size of the stator outer core is small, the first clamping block 520 and the second clamping block 530 of two adjacent clamping mechanisms 500 are likely to interfere with each other, so that the clamping of the stator outer core cannot be realized. Therefore, in another embodiment, the first clamping block 520 is provided with a first engaging tooth 521, the second clamping block 530 is provided with a second engaging tooth 531, and the first engaging tooth 521 and the second engaging tooth 531 of two adjacent clamping mechanisms 500 can be engaged. In the case that the size of the stator outer core is small, the first clamping block 520 and the second clamping block 530 of two adjacent clamping mechanisms 500 are not easily interfered, thereby being beneficial to clamping the stator outer core.
In order to facilitate the installation of the driving mechanism 300, the tooling device on the motor stator may further include an installation bracket 800, the driving mechanism 300 is connected to the annular gland 400 through the installation bracket 800, and the driving mechanism 300 is rotatably disposed on the installation bracket 800. Mounting of the drive mechanism 300 may be facilitated by a mounting bracket 800. Because the driving mechanism 300 is rotatably connected with the mounting bracket 800, when the driving mechanism 300 drives the annular turntable 200 to rotate, the stress of the driving mechanism 300 can be automatically adjusted, so that a certain position of the driving mechanism 300 can be prevented from being subjected to a large acting force, and the service life of the driving mechanism 300 can be prolonged.
In an alternative embodiment, the mounting bracket 800 may include a rotating bracket 840, the rotating bracket 840 is rotatably connected to the annular gland 400, and the rotating bracket 840 is sleeved on the driving mechanism 300. Since the rotating bracket 840 should be rotated and also be rotatably connected to the ring gland 400, it is inconvenient to arrange the rotating bracket 840. Therefore, in another alternative embodiment, the mounting bracket 800 may further include a first mounting block 810, a second mounting block 820 and a third mounting block 830, the first mounting block 810 is connected to the third mounting block 830 through the second mounting block 820, the first mounting block 810 and the third mounting block 830 are opposite to each other in the axial direction of the ring turntable 200, and the rotating bracket 840 is rotatably connected to the first mounting block 810 and the third mounting block 830, respectively. The arrangement of the rotating bracket 840 is further facilitated by the first mounting block 810, the second mounting block 820 and the third mounting block 830. The rotational axis of the rotational bracket 840 is parallel to the axis of the annular gland 400. Optionally, the rotating bracket 840 is provided with a rotating shaft, and the rotating bracket 840 is rotatably connected with the first mounting block 810 and the third mounting block 830 through the rotating shaft.
In one embodiment, the first mounting block 810 and the second mounting block 820 are a single structure, and the third mounting block 830 and the second mounting block 820 are separate structures. The third mounting block 830 may include a first mounting section 831 and a second mounting section 832 connected, the first mounting section 831 being connected to the annular gland 400, the second mounting section 832 being connected to the rotating bracket 840, and a thickness of the first mounting section 831 being equal to a thickness of the second mounting section 832 in the axial direction of the annular turntable 200. In this embodiment, the thickness of the first mounting section 831 is larger, so that the third mounting block 830 protrudes more, which is not favorable for the structural design of the tooling device on the motor stator. Therefore, in another embodiment, the thickness of the first mounting section 831 is smaller than the thickness of the second mounting section 832. Because first installation section 831 thickness is less, can reduce the protrusion of third installation piece 830, be favorable to the structural design of tool equipment on the motor stator.
The embodiment of the application further provides a stator press-mounting machine which comprises the motor stator upper tooling device in any embodiment.
While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the present embodiments are not limited to those precise embodiments, which are intended to be illustrative rather than restrictive, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope of the appended claims.
