Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a paint-impregnating support device for motor stator manufacturing. Background Technology

[0002] The insulation impregnation of motors mainly involves insulating impregnation varnish. The insulating impregnation varnish penetrates and fills the gaps and pores of coils, wire grooves or other insulation materials through the impregnation process. After curing, it bonds the coil wires into an insulating whole and forms a continuous insulating layer on its surface, thereby improving dielectric properties, mechanical properties, thermal conductivity and protective properties.

[0003] In existing methods, when immersing the motor stator in insulating varnish, a support rod is required to hold it inside the stator and to bind it with straps. The stator is then lifted into the insulating varnish by a crane. The lifted stator also needs to be tilted to prevent the end wiring from being immersed in the insulating varnish. This not only makes operation inconvenient but also poses a risk of the motor stator slipping. Therefore, an impregnation support device is needed to effectively control the stator and prevent the wiring from slipping into the insulating varnish. Utility Model Content

[0004] This utility model addresses the deficiencies in the prior art by providing a paint-impregnating support device for motor stator production.

[0005] This utility model is achieved through the following technical solution:

[0006] A varnish-impregnation support device for motor stator production includes an impregnation tank, a first hydraulic cylinder, a second hydraulic cylinder, a first support frame, a second support frame, a clamping shaft, a limiting clamping plate, a stator winding, and a wire clamping mechanism. The first and second hydraulic cylinders are fixedly installed at the bottom of the impregnation tank. The first support frame is fixedly installed at the top of the first hydraulic cylinder, and the second support frame is fixedly installed at the top of the second hydraulic cylinder. The clamping shaft is clamped at the top of the first and second support frames. The limiting clamping plate is fixedly connected to the clamping shaft. The stator winding is sleeved on the outside of the clamping shaft. The wire clamping mechanism is fixedly installed on the outside of the second support frame. The wire clamping mechanism includes a connecting seat, a rotating shaft, a support plate, a limiting screw, a pressure plate, and a knob. The connecting seat is fixedly installed on the outside of the second support frame. The rotating shaft is movably connected to the connecting seat. The support plate is fixedly installed at the top of the rotating shaft. The limiting screw is vertically fixed at both ends of the top of the support plate. The pressure plate is sleeved on the outside of the limiting screw. The knob is threadedly connected to the limiting screw.

[0007] In a preferred embodiment of this utility model, one end of the top of the first support frame is inclined, and the limiting plate is attached to one side of the first support frame;

[0008] The top slope of the first support frame fits into the limiting plate, increasing the contact area and ensuring the support effect.

[0009] In a preferred embodiment of the present invention, the top of the first support frame and the second support frame are provided with slots that cooperate with the locking shaft, and the extension height of the second cylinder corresponding to the second support frame is higher than the extension height of the first cylinder at the bottom of the first support frame.

[0010] The second support frame extends further than the second hydraulic cylinder, allowing the stator to be tilted, which facilitates the soaking of insulating varnish and the extension of the end wiring through the varnish.

[0011] In a preferred embodiment of the present invention, the rotating shaft is fixedly disposed at the bottom of one end of the support plate, and the support plate is located on the outer side of the top of the retaining shaft.

[0012] In a preferred embodiment of this utility model, the pressure plate has insertion holes at both ends that cooperate with the limiting screws;

[0013] The terminal is clipped onto the top of the support plate, and pressure is applied by the pressure plate to fix the terminal in place.

[0014] The beneficial effects of this utility model are:

[0015] This motor stator production varnish-impregnation support device reliably installs the motor stator and clamps it onto the top of the stator support frame. The device is controlled by a hydraulic cylinder to immerse the stator in insulating varnish. During the immersion process, the stator is prevented from slipping off, and the stator terminals are effectively fixed to prevent them from being immersed in the insulating varnish and affecting subsequent wiring installation. The stator installation is simple and reliable, ensuring the effectiveness of the insulating varnish impregnation. Attached Figure Description

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0021] like Figure 1-3 The illustrated impregnation support device for motor stator production includes an impregnation tank 1, a first hydraulic cylinder 2.1, a second hydraulic cylinder 2.2, a first support frame 3, a second support frame 4, a retaining shaft 5, a limiting plate 6, a stator winding 7, and a wire clamping mechanism 8. The first hydraulic cylinder 2.1 and the second hydraulic cylinder 2.2 are fixedly installed at the bottom of the impregnation tank 1. The first support frame 3 is fixedly installed at the top of the first hydraulic cylinder 2.1, and the second support frame 4 is fixedly installed at the top of the second hydraulic cylinder 2.2. The retaining shaft 5 is clamped at the top of the first support frame 3 and the second support frame 4. The limiting plate 6 is fixedly connected to the retaining shaft 5. Next, the stator winding 7 is sleeved outside the clamping shaft 5, and the wire clamping mechanism 8 is fixedly installed on the outside of the second support frame 4. The wire clamping mechanism 8 includes a connecting seat 81, a rotating shaft 82, a support plate 83, a limiting screw 84, a pressure plate 85, and a knob 86. The connecting seat 81 is fixed to the outside of the second support frame 4, the rotating shaft 82 is movably connected to the connecting seat 81, the support plate 83 is fixedly installed on the top of the rotating shaft 82, the limiting screw 84 is vertically fixed at both ends of the top of the support plate 83, the pressure plate 85 is sleeved outside the limiting screw 84, and the knob 86 is threadedly connected to the limiting screw 84.

[0022] Specifically, the top end of the first support frame 3 is inclined, the limiting plate 6 is attached to one side of the first support frame 3, the top of the first support frame 3 and the second support frame 4 are provided with slots that cooperate with the locking shaft 5, the extension height of the second support frame 4 corresponding to the second oil cylinder 2.2 is higher than the extension height of the first oil cylinder 2.1 at the bottom of the first support frame 3, the rotating shaft 82 is fixedly set at the bottom of one end of the support plate 83, the support plate 83 is located on the outer side of the top of the locking shaft 5, and the two ends of the pressure plate 85 are provided with insertion holes that cooperate with the limiting screw 84.

[0023] In this embodiment, firstly, both the first hydraulic cylinder 2.1 and the second hydraulic cylinder 2.2 are fully extended, so that the first support frame 3 and the second support frame 4 extend to the outside of the top of the impregnation tank 1. Then, the motor stator is sleeved on the outside of the clamping shaft 5, one end of the stator winding 7 contacts the outside of the limiting clamping plate 6, and the clamping shaft 5 is lifted. The two ends of the clamping shaft 5 are respectively clamped into the top grooves of the first support frame 3 and the second support frame 4. The limiting clamping plate 6 is located inside one side of the first support frame 3.

[0024] Furthermore, the stator winding 7 is effectively fixed at the terminal of the second support frame 4. First, the first support frame 3 retracts corresponding to the first hydraulic cylinder 2.1, causing the retaining shaft 5 to be tilted. The rotating shaft 82 is rotated so that the support plate 83 is positioned on the outer side of the top of the second support frame 4, and the terminal is secured between the two limiting screws 84. The pressure plate 85 is then installed, and the knob 86 is rotated to apply pressure to the pressure plate 85, thereby effectively fixing the secured terminal. The terminal is raised high to prevent it from being immersed in the impregnation tank 1. Then, the first hydraulic cylinder 2.1 and the second hydraulic cylinder 2.2 are controlled to retract synchronously, completely immersing the stator winding 7 in the insulating varnish in the impregnation tank 1 for insulation impregnation. This device can not only effectively control the impregnation process, but also prevent the stator winding 7 from separating from the retaining shaft 5, preventing the retaining shaft 5 from slipping and the stator winding 7 from falling. It also ensures that the terminal does not come into contact with the insulating varnish, achieving the ideal insulating varnish impregnation effect.
