Description

Technical Field

[0001] The invention belongs to the technical field of motor stator welding, and specifically relates to a motor stator welding device with a clamping device. Background Art

[0002] The motor stator is one of the core components of a motor, and cooperates with the rotor to achieve the conversion of electrical energy and mechanical energy. The stator is composed of an iron core, windings, a housing, and insulating materials; among them, the iron core is laminated by silicon steel sheets and is fixed into an integral body by laser welding or argon arc welding on the outer circle or end face of the iron core laminations for magnetic conduction and reduction of eddy current loss; currently, the lamination of the motor stator iron core is usually positioned by a central positioning column with a variable diameter value for the silicon steel sheets. After stacking the silicon steel sheets, the central positioning column is enlarged to keep the stacked silicon steel sheets coaxial. However, during this process, the gravity of the stacked silicon steel sheets all presses downward, and the pressure on the lower layer is relatively large when enlarging the central positioning column, and wear is likely to occur between the silicon steel sheets, resulting in difficulty in achieving concentricity. Or a fixed central positioning column adapted to the silicon steel sheets is used. However, since the inner diameter of the silicon steel sheet is adapted to the outside of the central positioning column, when the silicon steel sheet is sleeved on the outside of the central positioning column, a hammer is needed to make the silicon steel sheet sleeved on the outside of the central positioning column, thereby reducing the lamination efficiency of the silicon steel sheets. Therefore, a motor stator welding device with a clamping device is proposed. Summary of the Invention

Moreover, the weight of the stacked multiple iron cores is reduced by the support of the receiving rod, improving the efficiency of adjusting the coaxiality of the multiple iron cores;

[0026] In the present invention, the pressing component moves towards the support component, pushing the piston rod and the piston to inject air into the positioning component through the air injection pipe. During the movement of the piston, it contacts the stable frame and pushes the connecting piece to pull the gasket and the elastic member. At the same time, the pressing ring contacts the iron core, thereby pushing the iron core towards one end of the base. During the process of the pressing ring pushing the iron core, the gasket is pulled synchronously, thus achieving synchronous movement, reducing the friction between the wire groove of the iron core and the gasket, and further improving the production quality of the iron core.

Specific embodiments

[0037] 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.

[0038] As Figures 1 to 9 shown, the present invention provides a motor stator welding device with a clamping device, including a base 1, and further including:

[0039] A pressing component 2, the pressing component 2 is arranged at one end of the base 1;

[0040] A support component 3, the support component 3 is fixedly installed at the other end of the base 1, and a welding device is arranged on the base 1 near the support component 3;

[0041] A positioning component 4, the positioning component 4 is arranged in a circular array outside the support component 3;

[0042] An iron core 5, the iron core 5 is sleeved outside the positioning component 4;

[0043] Among them, the support component 3 includes a support cylinder 31 fixedly installed on the base 1, and an injection pipe 32 is fixedly installed inside the support cylinder 31;

[0044] The positioning component 4 includes a shunt pipe 44 fixedly installed on the inner wall of the support cylinder 31, the shunt pipe 44 is communicated with one end of the injection pipe 32 through a connecting pipe 45, a sleeve 43 passing through the support cylinder 31 is fixedly installed outside the shunt pipe 44, a movable rod 42 is movably sleeved inside the sleeve 43, and a connecting rod 41 is fixedly installed at one end of the movable rod 42;

[0045] The connecting rod 41 is communicated with the shunt pipe 44 through the movable rod 42 and the sleeve 43;

[0046] The iron core 5 is sleeved outside the support cylinder 31, and the wire grooves of the iron core 5 are in contact with the outside of the positioning assembly 4.

[0047] A plurality of iron cores 5 are sequentially sleeved outside the support cylinder 31, and the wire grooves are clamped outside the receiving rod 41. The iron core 5 is supported by the receiving rod 41. The pressing assembly 2 moves towards the iron core 5. During the movement, air is injected into the shunt pipe 44 through the air injection pipe 32 and the connecting pipe 45. The gas enters the receiving rod 41 through the sleeve 43 and the movable rod 42. The air pressure in the receiving rod 41 gradually increases, causing the receiving rod 41 and the movable rod 42 to move upward along the sleeve 43. Since the positioning assembly 4 is arranged in an annular array outside the support cylinder 31, the plurality of iron cores 5 are clamped and supported coaxially with the support cylinder 31 through the synchronous movement of the receiving rod 41. During the adjustment of the iron core 5 by the receiving rod 41, the phenomenon that the plurality of iron cores 5 are stacked and in contact with each other to cause friction can be avoided. The weight of the stacked plurality of iron cores 5 is reduced by the support of the receiving rod 41, and the efficiency of adjusting the coaxiality of the plurality of iron cores 5 is improved;

[0048] The pressing assembly 2 applies pressure to the iron core 5, causing the plurality of iron cores 5 to move along the receiving rod 41 towards one end of the base 1. After applying pressure, welding is performed by welding equipment. The pressing assembly 2 moves in the reverse direction to discharge the gas in the support assembly 3 and the receiving rod 41, facilitating the removal of the welded stator.

[0049] As Figure 4 shown, rubber pads 46 are arranged on both sides of the receiving rod 41, and the rubber pads 46 are in communication with the inside of the receiving rod 41;

[0050] A deformation prevention pad is arranged on the side of the rubber pad 46.

[0051] The iron core 5 is sequentially sleeved outside the support cylinder 31 and the receiving rod 41. The pressing assembly 2 moves towards the support assembly 3. Air is injected into the receiving rod 41 through the support assembly 3. The gas enters the rubber pad 46, causing it to expand and the deformation prevention pad to contact the inner wall of the wire groove of the iron core 5. The wire grooves of the plurality of iron cores 5 are aligned by the rubber pads 46 on both sides. At the same time, the deformation prevention pad is used to prevent the rubber pad 46 from contacting the iron core 5 and getting stuck in the gap between the two iron cores 5.

[0052] As Figure 1 and Figure 5 shown, a piston 34 is movably sleeved inside the support cylinder 31, and a piston rod 33 is fixedly installed at one end of the piston 34;

[0053] The other end inside the air injection pipe 32 is fixedly installed with a cross stabilizer, and the piston rod 33 passes through the cross stabilizer;

[0054] The pressure - applying assembly 2 includes a hydraulic device 23 fixedly installed on the base 1. A guide rod 21 is fixedly installed on the base 1. The output end of the hydraulic device 23 is fixedly installed with a support frame 22 that slides outside the guide rod 21. A pressure - applying ring 24 is fixedly installed on the support frame 22.

[0055] The output end of the hydraulic device 23 is coaxial with the piston rod 33. When the pressure - applying ring 24 moves towards the support cylinder 31, the pressure - applying ring 24 is sleeved outside the support cylinder 31 and the receiving rod 41 and contacts the iron core 5.

[0056] By sleeving the iron core 5 outside the receiving rod 41, starting the hydraulic device 23 to push the pressure - applying ring 24 towards the support assembly 3. During the movement, the output end of the hydraulic device 23 contacts the piston rod 33, and pushes the piston 34 towards the other end of the injection pipe 32, and injects the gas in the injection pipe 32 into the shunt pipe 44 and the receiving rod 41 through the connecting pipe 45.

[0057] When the pressure - applying ring 24 contacts the iron core 5, the pressure - applying ring 24 pushes the iron core 5 to move along the outside of the receiving rod 41, applies pressure to the iron core 5 through the pressure - applying ring 24, and then welds it through welding equipment to form a stator.

[0058] As Figures 5 to 9 shown, the positioning assembly 4 further includes a gasket 416 sleeved inside the receiving rod 41. An arc - shaped through - slot 417 is opened at one end of the top of the receiving rod 41. The gasket 416 passes through the arc - shaped through - slot 417 and fits against the top of the receiving rod 41.

[0059] The iron core 5 is sleeved outside the receiving rod 41, and the wire groove contacts the top of the gasket 416.

[0060] One end of the gasket 416 is located inside the receiving rod 41 and is connected to the inner wall of the receiving rod 41 through an elastic member 418.

[0061] One end of the injection pipe 32 is movably sleeved with a stabilizing frame 411. A connecting member 413 is fixedly installed on the side of the stabilizing frame 411. A reset elastic member 412 that supports the stabilizing frame 411 is arranged inside the injection pipe 32.

[0062] A guiding frame 414 is fixedly installed on the side of the base 1. A C - type buckle 415 is fixedly installed outside the guiding frame 414. The gasket 416 passes through the C - type buckle 415 and is connected to the connecting member 413.

[0063] The pressure - applying component 2 moves towards the support component 3, pushing the piston rod 33 and the piston 34 to inject gas into the positioning component 4 through the injection pipe 32. During the movement of the piston 34, it contacts the stabilizing frame 411, and pushes the connecting piece 413 to pull the gasket 416 and the elastic piece 418. At the same time, the pressure - applying ring 24 contacts the iron core 5, thereby pushing the iron core 5 to move towards one end of the base 1. During the process of the pressure - applying ring 24 pushing the iron core 5, it synchronously pulls the gasket 416, thus achieving synchronous movement, reducing the friction between the wire groove of the iron core 5 and the gasket 416, and further improving the production quality of the iron core 5.

[0064] The working principle and usage process of the present invention:

[0065] A plurality of iron cores 5 are successively sleeved outside the support cylinder 31, and the wire grooves are clamped outside the receiving rod 41. The iron cores 5 are supported by the receiving rod 41. The pressure - applying component 2 moves towards the iron core 5. During the movement, gas is injected into the shunt pipe 44 through the injection pipe 32 and the connecting pipe 45. The gas enters the receiving rod 41 through the sleeve 43 and the movable rod 42. The air pressure in the receiving rod 41 gradually increases, causing the receiving rod 41 and the movable rod 42 to move upward along the sleeve 43. Since the positioning component 4 is arranged in a circular array outside the support cylinder 31, the synchronous movement of the receiving rod 41 clamps and supports a plurality of iron cores 5 to be coaxial with the support cylinder 31. During the process of adjusting the iron cores 5 by the receiving rod 41, the phenomenon that a plurality of iron cores 5 stack and contact each other, resulting in friction, can be avoided. And the weight of the stacked iron cores 5 is reduced by the support of the receiving rod 41, improving the efficiency of adjusting the coaxiality of a plurality of iron cores 5;

[0066] When the gas enters the rubber pad 46, the rubber pad 46 expands, and the anti - deformation pad contacts the inner wall of the wire groove of the iron core 5. The wire grooves of a plurality of iron cores 5 are aligned by the rubber pads 46 on both sides. At the same time, the anti - deformation pad prevents the rubber pad 46 from being stuck in the gap between two iron cores 5 when contacting the iron core 5;

[0067] The pressure - applying component 2 moves towards the support component 3, pushing the piston rod 33 and the piston 34 to inject gas into the positioning component 4 through the injection pipe 32. During the movement of the piston 34, it contacts the stabilizing frame 411, and pushes the connecting piece 413 to pull the gasket 416 and the elastic piece 418. At the same time, the pressure - applying ring 24 contacts the iron core 5, thereby pushing the iron core 5 to move towards one end of the base 1. During the process of the pressure - applying ring 24 pushing the iron core 5, it synchronously pulls the gasket 416, thus achieving synchronous movement and reducing the friction between the wire groove of the iron core 5 and the gasket 416;

[0068] The hydraulic device 23 is started to push the pressure - applying ring 24 towards the support component 3. During the movement, the output end of the hydraulic device 23 contacts the piston rod 33, and pushes the piston 34 to move towards the other end of the injection pipe 32, and injects the gas in the injection pipe 32 into the shunt pipe 44 and the receiving rod 41 through the connecting pipe 45;

[0069] The pressure - applying ring 24 contacts the iron core 5. The iron core 5 is pushed to move along the outside of the receiving rod 41 through the pressure - applying ring 24, and pressure is applied to the iron core 5 through the pressure - applying ring 24. Then, it can be welded by a welding device to form a stator.

[0070] The pressure - applying assembly 2 applies pressure to the iron core 5, causing multiple iron cores 5 to move along the receiving rod 41 towards one end of the base 1. After applying pressure, it is welded by a welding device. The pressure - applying assembly 2 moves in the reverse direction to discharge the gas in the receiving rod 41 of the support assembly 3, facilitating the removal of the welded stator.
