Description

Technical Field

[0001] The utility model relates to the technical field of stator core shaping, in particular to a shaping device for a variable-frequency motor stator core. Background Technique

[0002] When a stator core is produced, copper wires need to be wound inside it. However, the copper wires are rather messy after winding. Therefore, it is necessary to sort and shape them to ensure the neatness of the stator core, so as to facilitate the subsequent assembly of the motor.

[0003] As disclosed in the authorized publication number CN209571923U, a shaping device for a variable-frequency motor stator core is disclosed, which can prevent the pressing part of the pressing device from deforming and achieve an ideal pressing effect. A shaping device (1) for a variable-frequency motor stator core shapes the stator core (61) wound with a coil (63), and includes a first clamp (2) and a second clamp (3). The first clamp has a first cylindrical part (21) for accommodating the stator core, and the second clamp has a second cylindrical part (31). The second cylindrical part has an annular end face (311a) for pressing the outer periphery of the end face of the stator core from one side in the axial direction of the stator core accommodated in the first cylindrical part. A plurality of first clamp recesses (211) are formed in the inner peripheral surface of the first cylindrical part in the circumferential direction, and a plurality of second clamp protrusions (312a) for engaging with the first clamp recesses (211) are formed in the outer peripheral surface of the second cylindrical part in the circumferential direction.

[0004] However, when the existing stator core shaping device is in use, the user needs to send the stator core into the interior of the shaping device. Since the downward pressure of the shaping device is relatively large, it is easy to cause injury to the user's hand when the device malfunctions. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A shaping device for a variable-frequency motor stator core includes a lower support mechanism and an upper support mechanism. The upper support mechanism is located at the top of the lower support mechanism. The lower support mechanism includes a support base.

A first connecting cylinder is fixedly installed around the top end of the support base. A pneumatic device is fixedly installed at the rear end of the support base. A sliding block is movably installed in the middle of the top end of the support base. A first clamping cylinder is fixedly installed at the top end of the sliding block. A slider is fixedly installed at the bottom end of the sliding block.

[0008] Preferably, the lower support mechanism further includes a sliding groove, in which a slider is movably installed. The sliding groove is opened at the top end of the extension plate, and the extension plate is fixedly installed on the upper side of the front end of the support base.

[0012] Preferably, a second clamping cylinder is fixedly installed at the bottom end of the sliding plate, and a pneumatic telescopic shaft is fixedly installed in the middle of the second clamping cylinder.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 4 As shown, a technical solution provided by the present invention:

[0023] The shaping device for the stator core of a variable-frequency motor includes a lower support mechanism 101 and an upper support mechanism 102. The upper support mechanism 102 is located at the top of the lower support mechanism 101. The lower support mechanism 101 includes a support base 103. A fixing plate 104 is fixedly installed at the bottom end of the support base 103. A fixing groove 105 is opened on the fixing plate 104. First connecting cylinders 106 are fixedly installed around the top end of the support base 103. A pneumatic device 201 is fixedly installed at the rear end of the support base 103. A sliding block 202 is movably installed in the middle of the top end of the support base 103. A first clamping cylinder 203 is fixedly installed at the top end of the sliding block 202. A slider 204 is fixedly installed at the bottom end of the sliding block 202.

[0024] Through the above solution, the fixing plate can be installed through the fixing groove, so that the support base is fixed. The sliding rod can be installed through the first connecting cylinder. The sliding block can be slid by the pneumatic device. The stator core can be clamped by the first clamping cylinder. The sliding of the sliding block can be made stable by the slider. The sliding out of the sliding block makes it convenient for the user to take and place the stator core, and at the same time prevents the user's hand from being squeezed and injured due to equipment operation errors.

[0025] In this embodiment, preferably, the lower support mechanism 101 further includes a sliding groove 205. A slider 204 is movably installed in the sliding groove 205. The sliding groove 205 is opened at the top end of an extension plate 206. The extension plate 206 is fixedly installed on the upper side of the front end of the support base 103.

[0026] Through the above solution, by sliding the slider in the sliding groove, the sliding plate can slide stably on the extension plate.

[0027] In this embodiment, preferably, the upper support mechanism 102 includes a hydraulic actuator 301. The bottom end of the hydraulic actuator 301 is fixedly installed with a connecting plate 302. The connecting plate 302 is movably installed in the middle of the top end of the support plate 404. Four sides of the top end of the connecting plate 302 are fixedly installed with connecting screws 303.

[0028] Through the above solution, by passing the connecting screw through the connecting plate, the hydraulic actuator can be fixed to the top end of the support plate.

[0029] In this embodiment, preferably, second connecting cylinders 304 are fixedly installed around the support plate 404. Sliding rods 305 are fixedly installed inside the second connecting cylinders 304. The bottom ends of the sliding rods 305 are fixedly installed inside the first connecting cylinder 106.

[0030] Through the above solution, the sliding rod can be installed through the second connecting cylinder. Through the sliding rod, the sliding plate can be slid up and down, so that the shaping and pressing are more stable.

[0031] In this embodiment, preferably, a sliding plate 306 is movably installed in the middle of the sliding rod 305. A hydraulic rod 401 is fixedly installed at the top end of the sliding plate 306. The top end of the hydraulic rod 401 penetrates through the support plate 404 and is fixedly installed at the bottom end of the hydraulic actuator 301.

[0032] Through the above solution, the hydraulic rod is driven by the hydraulic actuator to press down, so that the sliding plate is driven to press down on the sliding rod.

[0033] In this embodiment, preferably, a second clamping cylinder 402 is fixedly installed at the bottom end of the sliding plate 306. A pneumatic telescopic shaft 403 is fixedly installed in the middle of the second clamping cylinder 402.

[0034] Through the above solution, the top end of the stator core can be clamped through the second clamping cylinder, and the copper wire on the stator core can be extruded. At the same time, the pneumatic telescopic shaft is cooperated to expand and extrude on the stator core, so that the shaping of the stator core is completed.

[0035] When the shaping device for the stator core of the variable-frequency motor in this embodiment is in use, the user starts the pneumatic device 201 to make the slider 204 slide in the chute, so that the sliding block 202 drives the clamping plate to slide out on the extension plate 206. After sliding out, the user places the stator core in the first clamping cylinder 203. At this time, the pneumatic device 201 drives the sliding block 202 to reset, so that the first clamping cylinder 203 drives the stator core to move to the bottom end of the second clamping cylinder 402. At the same time, the hydraulic device 301 drives the hydraulic rod 401 to work, so that the sliding plate 306 is driven to slide on the sliding rod 305, so that the second clamping cylinder 402 and the pneumatic telescopic shaft 403 are driven to press down. When pressing down, the pneumatic telescopic shaft 403 is inserted into the stator core, and at the same time, the second clamping cylinder 402 clamps the top end of the stator core. At this time, the pneumatic telescopic shaft 403 expands from the inside of the stator core through pneumatic means, and cooperates with the downward pressure generated by the hydraulic device 301 to make the copper wire wound on the stator core be extruded and shaped, so that the stator core is completed for shaping. After shaping, the hydraulic device 301 drives the second clamping cylinder 402 and the pneumatic telescopic shaft 403 to reset, and then the pneumatic device 201 drives the sliding block 202 to slide out. At this time, the user takes out the shaped stator core and puts the unshaped stator core in to continue the shaping work. The device drives the sliding plate 306 to slide on the extension plate 206 through the pneumatic device 201, so that the second clamping cylinder 402 is driven to slide out, so that it is convenient for the user to take and place the stator core, and at the same time, it prevents the user's hand from being squeezed and injured due to equipment operation errors.
