Technical Field

[0001] The utility model relates to the technical field of motor assembly, in particular to a stator wire embedding bracket device. Background Art

[0002] The stator is the stationary part of the motor or generator. The stator consists of three parts: the stator core, the stator winding and the frame.

[0003] During stator production, stator wire rods must be inserted into the inner ring grooves and secured. Therefore, the stator must be placed horizontally on a bracket and secured there. Patent publication number CN217087480U discloses a stator wire-inserting bracket. This device supports the stator through the cooperation of left and right brackets, addressing the problem of the stator falling when placed directly on a workbench for wire insertion.

[0004] In the actual manual wire embedding process, the stator position needs to be adjusted according to the installation progress in order to better fix the wire rods. However, the device cannot rotate the stator to change the working position, which increases the difficulty of wire rod installation and has low practicality. Therefore, a stator wire embedding bracket device is urgently needed to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned problem that the stator cannot be rotated to change the working orientation, which increases the difficulty of installing the wire rod and has low practicality, the present utility model is proposed.

[0006] Therefore, the purpose of the present invention is to provide a stator wire embedding bracket device, which aims to solve the problem that the stator cannot be rotated to change the working orientation, resulting in increased difficulty in installing the wire rod and low practicality.

[0008] As a preferred solution of the stator wire embedding bracket device of the present invention, one of the support brackets is fixedly connected to the base, and the other support bracket is slidably connected to the base.

[0009] As a preferred solution of the stator wire embedding bracket device of the present invention, wherein: a screw is rotatably connected to the base, a screw sleeve is threadedly engaged on the screw, and the screw sleeve is fixedly connected to the slidable support frame.

[0011] As a preferred solution of the stator wire embedding bracket device of the present invention, one side of the transmission plate is fixedly connected to a hand wheel, and the other side is fixedly connected to a fixing rod, the fixing rod is sleeved with a fixing tube, and the fixing tube is fixedly connected to the support frame.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model is used to place the stator through two supporting rollers.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a stator wire embedding bracket device, which includes a base 1, two support frames 2 are connected to the base 1, and a support roller 201 is rotatably connected to the support frame 2. A driving mechanism 3 is installed on one support frame 2, and the driving mechanism 3 includes a face gear 301, and one side of the face gear 301 is transmission-connected with a connecting shaft 304, and one end of the connecting shaft 304 is transmission-connected with the support roller 201 through a chain 305. A transmission plate 306 is snap-fitted on the face gear 301, and the transmission plate 306 is used to drive the face gear 301 to rotate.

[0026] In the above technical solution, the two support frames 2 are arranged in parallel, so that the stator can be placed horizontally between the two support rollers 201. When the transmission plate 306 is engaged with the face gear 301, the face gear 301 drives the connecting shaft 304 to rotate when the transmission plate 306 rotates. The connecting shaft 304 drives the support roller 201 connected to it to rotate through the chain 305, so that the support roller 201 can adjust the angle of the stator in the radial direction, thereby changing the working orientation of the wire rod, making it easier for personnel to work from a more convenient angle.

[0027] During actual operation, the surface of the support roller 201 is wrapped with an anti-slip rubber pad, which can increase the friction when in contact with the stator. On the one hand, it prevents the stator from axially sliding on the support roller 201, and on the other hand, it facilitates the support roller 201 to drive the stator to rotate radially.

[0028] One support frame 2 is fixedly connected to the base 1 , and the other support frame 2 is slidably connected to the base 1 .

[0029] In the above technical solution, the movable support frame 2 can be slidably adjusted on the base 1, so that the distance between the two support rollers 201 can be changed, so that the two support rollers 201 can be adjusted and adapted according to the size of the stator, thereby improving the scope of application.

[0030] A screw rod 101 is rotatably connected to the base 1 , a screw sleeve 102 is threadedly engaged on the screw rod 101 , and the screw sleeve 102 is fixedly connected to the slidable support frame 2 .

[0031] In the above technical solution, one end of the screw rod 101 is fixedly connected to a rotating wheel. Rotating the rotating wheel can make the screw rod 101 drive the screw sleeve 102 to move, and the screw sleeve 102 drives the support frame 2 to move synchronously to achieve spacing adjustment.

[0032] Two support bases 302 are slidably connected to the face gear 301 , and the support base 302 is fixedly connected to the support frame 2 . A transmission gear 303 is meshedly connected to one side of the face gear 301 , and the transmission gear 303 is coaxially fixedly connected to the connecting shaft 304 .

[0033] In the above technical solution, the support seat 302 has a inferior arc structure, and two arc plates are fixedly connected to the support seat 302. The two arc plates are vertically arranged and respectively arranged on the upper and lower sides of the face gear 301. Through the limiting of the support seat 302, the face gear 301 can rotate in situ.

[0034] In addition, the connecting shaft 304 is rotatably provided on the support frame 2 , and two sprockets are meshedly connected to the chain 305 , one sprocket is coaxially connected to the connecting shaft 304 , and the other sprocket is coaxially connected to the support roller 201 .

[0035] One side of the transmission plate 306 is fixedly connected to a hand wheel 307 , and the other side is fixedly connected to a fixing rod 308 . A fixing cylinder 309 is sleeved on the fixing rod 308 , and the fixing cylinder 309 is fixedly connected to the support frame 2 .

[0036] In the above technical solution, the fixed rod 308 can slide vertically in the fixed cylinder 309 and drive the transmission plate 306 to move synchronously. When the transmission plate 306 descends to engage with the face gear 301, rotating the handwheel 307 can drive the face gear 301 to rotate synchronously.

[0037] It can be understood that a plurality of protrusions are fixedly provided in a circular shape with equal intervals on the side of the transmission plate 306 facing the face gear 301, and a positioning groove adapted to the protrusions is opened on the side of the face gear 301 facing the transmission plate 306. When the protrusion is embedded in the positioning groove, the transmission plate 306 can drive the face gear 301 to rotate synchronously.

[0038] During use, first rotate the screw 101 to drive the support frame 2 connected to the screw sleeve 102 to slide, so that the distance between the two support rollers 201 is smaller than the positioning diameter, and then place the stator horizontally between the two support rollers 201 to fix the stator wire rods.

[0039] By driving the hand wheel 307 to move downward, the fixed rod 308 slides along the fixed cylinder 309. When the protrusion of the transmission plate 306 is embedded in the positioning groove of the face gear 301, the hand wheel 307 is turned, and the transmission plate 306 drives the face gear 301 to rotate synchronously. The face gear 301 engages with the transmission gear 303 to drive the connecting shaft 304 to rotate. The connecting shaft 304 drives the support roller 201 connected to it to rotate through the chain 305, so that the support roller 201 can drive the stator to rotate and adjust in the radial direction to achieve azimuth adjustment.

[0040] Example 2

[0041] Reference Figure 4 , which is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: a brake plate 310 is slidably connected to the fixed cylinder 309, a spring 1 311 is elastically connected between the brake plate 310 and the support frame 2, and a spring 2 312 is elastically connected between the brake plate 310 and the transmission plate 306.

[0042] In the above technical solution, when the handwheel 307 is not affected by external force, the spring 1 311 can drive the brake plate 310 to rise. Since the brake plate 310 is vertically slidably connected to the fixed cylinder 309, when the brake plate 310 is engaged with the face gear 301, the rotation of the face gear 301 can be restricted. When the brake plate 310 rises, the transmission plate 306 is driven to rise through the spring 2 312 to cancel the engagement with the face gear 301. At this time, turning the handwheel 307 cannot drive the face gear 301 to rotate, which can avoid erroneous operation during work, thereby driving the stator to rotate and affecting the wire embedding work.

[0043] Among them, a plurality of protrusions are fixed in a ring-shaped and equidistant manner on the side of the brake plate 310 facing the face gear 301, and a positioning groove adapted to the protrusions is opened on the side of the face gear 301 facing the brake plate 310. When the protrusion is embedded in the positioning groove, the brake plate 310 can limit the rotation of the face gear 301.

[0044] It is understandable that both ends of the second spring 312 are in sliding contact with the transmission plate 306 and the brake plate 310 respectively, so that the transmission plate 306 does not generate motion interference with the brake plate 310 when rotating.

[0045] In addition, the elastic force of spring 1 311 is smaller than the elastic force of spring 2 312 . When the hand wheel 307 descends, spring 1 311 is compressed first, causing the brake plate 310 to leave the face gear 301 , and then spring 2 312 is compressed, causing the transmission plate 306 to engage with the face gear 301 .

[0046] The remaining structures are the same as those of Example 1.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
