Description

Technical Field

[0001] The present invention relates to the technical field of motor production, and in particular to automatic production equipment for motor stator cores and a working method thereof. Background Art

[0002] The stator and rotor are extremely important components of the motor, and the stator and rotor cores are both stacked with silicon steel sheets. The motor silicon steel sheet stacking process is an important process in motor manufacturing. It refers to stacking silicon steel sheets together according to a certain pattern to form the motor's core. Generally speaking, the motor silicon steel sheet stacking process includes the following steps: first, the silicon steel sheets are cut and punched according to the design requirements; then, the silicon steel sheets are stacked according to a certain pattern; during the stacking process, professional fixtures and positioning tools are required to ensure the accurate position and size of the silicon steel sheets. Finally, the stacked silicon steel sheets are pre-fixed by welding and other methods to form the motor's core.

[0003] In the existing patent announcement number CN116117398A, a motor stator welding device is disclosed, which includes a workbench, a placement structure, a fixing structure, a welding structure, an air suction structure, a driving structure and a limiting structure.

The placement structure rotates while the fixing structure automatically fixes the motor stator.

[0004] However, in the above technical solution, the corresponding stacking process is not disclosed. The stacked silicon steel sheets can only be taken and placed on the first connecting column manually, which is time-consuming and labor-intensive, with a low degree of automation.

[0038] See also Figure 1-7 The present invention provides a technical solution: an automatic production device for a motor stator core and a working method thereof, comprising a support seat 8, a welding part 4, a feeding barrel 3, a limiting part and a stacking part,

[0039] The welding part 4 and the limiting part are both arranged on the upper side of the support seat 8, the limiting part includes a chassis 2, the chassis 2 is rotatably arranged on the support seat 8, the upper end of the chassis 2 is fixedly connected with four groups of limiting vertical plates 101, the upper end of the limiting vertical plates 101 is fixedly connected with a support ring 104, a plurality of silicon steel sheet bodies 6 are stacked between the four groups of limiting vertical plates 101, the welding part 4 includes a welding gun 401 that can be moved up and down, and the welding gun 401 is arranged on one side of the limiting vertical plate 101;

[0040] A plurality of silicon steel sheet bodies 6 are stacked in disorder in the loading barrel 3. A loading port 301 is provided through one side of the lower end of the loading barrel 3. The height of the loading port 301 is equal to the thickness of a single silicon steel sheet body 6. The stacking portion includes a limiting ring 1. A feeding port 115 adapted to the loading port 301 is provided through one side of the limiting ring 1. A cylinder assembly is provided on one side of the loading barrel 3. An arc-shaped push plate 302 is provided at the driving end of the cylinder assembly. The arc-shaped push plate 302 pushes the single silicon steel sheet body 6 into the limiting ring 1.

[0041] A rotatable and liftable sorting disk 102 is arranged on the inner side of the limit ring 1, a plurality of movable baffles 103 are arranged on the lower end of the limit ring 1, and a lifting assembly is arranged on the upper side of the limit ring 1. The lifting assembly drives the limit ring 1 to descend and dock with the limit part, and the sorting disk 102 pushes the silicon steel sheet body 6 in the limit ring 1 into the four groups of limit vertical plates 101.

[0042] First, the staff needs to place a batch of silicon steel sheet bodies 6 in the loading barrel 3 in a disordered manner in advance, and drive the arc push plate 302 to move through the cylinder assembly, and the arc push plate 302, the single silicon steel sheet body 6, the loading port 301 and the feed port 115 are all at the same height, so that the arc push plate 302 pushes the silicon steel sheet body 6 at the bottom, pushes out the loading port 301, and passes through the feed port 115 into the limit ring 1, completing the screening and feeding of the single silicon steel sheet body 6;

[0043] The silicon steel sheet body 6 falls on several baffles 103 in the limiting ring 1, and then the limiting ring 1 is driven to descend by the lifting assembly, and the lower end of the limiting ring 1 is connected to the support ring 104 to ensure the stability of the material discharge, and then the baffle 103 is expanded outward, so that the silicon steel sheet body 6 loses support and falls, and the support ring 104 is connected to the four groups of limiting vertical plates 101, so that the inner side of the support ring 104 forms a limiting opening that matches the silicon steel sheet body 6. If the overall position of the silicon steel sheet body 6 is matched with the limiting opening, that is, the four groups of limiting vertical plates 101, the silicon steel sheet body 6 falls directly into the four groups of limiting vertical plates 101; on the contrary, the overall position of the silicon steel sheet body 6 is not aligned with the limiting opening, and the silicon steel sheet body 6 falls on the upper side of the support ring 104, and then descends through the sorting plate 102 and contacts with the silicon steel sheet body 6, and then rotates and adjusts the angle with the sorting plate 102 until the overall angle of the silicon steel sheet body 6 The degree is adapted to the four groups of limit vertical plates 101, so that the silicon steel sheet body 6 falls into the four groups of limit vertical plates 101; then the limit ring 1 rises and resets, so that the feed port 115 is re-aligned with the loading port 301, and re-loading can be performed, and the above steps are repeated to sequentially align and stack the silicon steel sheet bodies 6 until a specified number of silicon steel sheet bodies 6 are neatly stacked in the limit vertical plates 101; then the chassis 2 drives the limit vertical plates 101 and several silicon steel sheet bodies 6 to rotate intermittently, and cooperates with the up and down movement of the welding gun 401, so that the welding gun 401 welds several silicon steel sheet bodies 6 through the gaps between the limit vertical plates 101 to form a whole, and then the staff removes it, and the processing of the stator core is completed, which improves work efficiency. Each silicon steel sheet body 6 is arranged, aligned and stably limited to prevent its deviation, thereby ensuring the neatness during welding and improving product quality.

[0044] The upper end of the limiting ring 1 is fixedly connected to a fixing disk 106, and the upper end of the fixing disk 106 is fixedly connected to a fixing sleeve 107. The inner side of the fixing sleeve 107 is provided with an internal thread. The upper end of the sorting disk 102 is provided with a threaded column 105, which passes through the fixing sleeve 107 and is threadedly connected thereto.

[0045] Preferably, when it is necessary to drive the sorting disk 102 to descend and drive the silicon steel sheet body 6 to rotate, so as to adjust the angular position, the threaded column 105 is driven to rotate relative to the fixed sleeve 107. The threaded column 105 is threadedly connected to the fixed sleeve 107, so that the threaded column 105 can drive the sorting disk 102 to descend while driving it to rotate. That is to say, the sorting disk 102 rotates and moves downward until it contacts the silicon steel sheet body 6, and drives it to rotate accordingly through friction, adjusts its own position until it matches the limit opening and falls into the four sets of limit vertical plates 101. Only by rotating the threaded column 105, the sorting disk 102 can be synchronously lowered and rotated, and the sorting and stacking of the silicon steel sheet body 6 can be completed, which is highly practical.

[0046] The upper end of the support seat 8 is fixedly connected to a plurality of support rods, the upper ends of the support rods are fixedly connected to a top plate 801, the upper side of the top plate 801 is rotatably connected to a gear 9, straight key grooves are provided on both sides of the threaded column 105, the threaded column 105 passes through the gear 9 and is slidably connected thereto, a driving key is provided on the inner side of the gear 9, the lower end of the top plate 801 is fixedly connected to a motor component, the driving end of the motor component is provided with a gear 2 901, and the gear 2 901 is meshingly connected with the gear 19.

[0047] Preferably, the motor drives gear 2 901 to rotate, which in turn drives gear 1 9 to rotate through meshing connection, and transmits torque between the straight keyway and the drive key, so that gear 1 9 drives the threaded column 105 to rotate without affecting the up and down movement of the threaded column 105.

[0048] The lower end of the threaded column 105 is fixedly connected to a circular plate 108 , and the lower end of the circular plate 108 is fixedly connected to a plurality of spring telescopic rods 1 , and the lower end of the spring telescopic rods 1 is connected to the sorting plate 102 .

[0049] Preferably, since the threaded column 105 drives the sorting disk 102 to rotate and descend at the same time, when the sorting disk 102 contacts the silicon steel sheet body 6, it will move downward while rotating, and the silicon steel sheet body 6 that is not aligned with the limit opening is supported by the support ring 104 and cannot move downward. Therefore, a circular plate 108 and a plurality of spring telescopic rods are provided. When the sorting disk 102 contacts the silicon steel sheet body 6, the circular plate 108 drives the sorting disk 102 to rotate while descending, and drives the silicon steel sheet body 6 to rotate. The spring telescopic rods are compressed to adapt, so that the silicon steel sheet body 6 can be aligned and fall, which is highly practical.

[0050] The baffle 103 passes through the lower side of the limiting ring 1 and slides with it. The outer side of the baffle 103 is fixedly connected with an arc plate 109. A plurality of spring retractable rods 110 are arranged between the arc plate 109 and the limiting ring 1. An inclined groove is opened on the baffle 103, and a spring telescopic rod 111 is slidably arranged in the inclined groove. The upper end of the spring telescopic rod 111 is connected with a sliding block 112, and the sliding block 112 is slidably connected to the outer side of the limiting ring 1.

[0051] Preferably, in the initial state, the spring retractable rod 110 causes the arc plate 109 to drive the baffles 103 to merge with each other, thereby supporting the silicon steel sheet body 6. When the baffle 103 needs to be driven to expand, a plurality of sliding blocks 112 slide on the outside of the limit ring 1, thereby driving the spring telescopic rod 111 to move in an annular manner. The spring telescopic rod 111 extends into the inclined groove, so that the spring telescopic rod 111 moves in an annular manner and slides in the inclined groove, thereby driving the baffle 103 to move outward, so that the plurality of baffles 103 can be expanded to each other, so that the silicon steel sheet body 6 falls;

[0052] When merging is required, the baffle 103 is reset by the reset action of the spring retractable rod 110, thereby causing the spring telescopic rod 111 to reset along the inclined groove.

[0053] A rubber ring 113 is fixedly connected to the outer side of the support ring 104 , and a rubber layer is provided at the lower end of the second spring telescopic rod 111 , and the second spring telescopic rod 111 corresponds to the rubber ring 113 .

[0054] Preferably, when the limit ring 1 descends and contacts the support ring 104, the spring telescopic rod 111 contacts the rubber ring 113 and compresses the spring telescopic rod 111. Since a rubber layer is provided at the lower end of the spring telescopic rod 111, the friction force between the spring telescopic rod 111 and the rubber ring 113 is further increased, so that the spring telescopic rod 111 and the sliding block 112 are fixed in position. Then, the limit ring 1 rotates relative to the support ring 104, and the rotation direction is opposite to the movable direction of the sliding block 112. The limit ring 1 drives the plurality of baffles 103 to rotate, so that the inclined groove of the baffle 103 is restricted by the spring telescopic rod 111, so that the baffle 103 is expanded outward, thereby causing the silicon steel sheet body 6 to fall. That is to say, after the limit ring 1 is connected to the support ring 104, the baffle 103 is opened again, thereby reducing the height of the silicon steel sheet body 6 falling, ensuring a stable fall without damaging its own surface quality.

[0055] The middle side of the support rod is fixedly connected with a center plate 802, the lower side of the top plate 801 is fixedly connected with an internal thread sleeve 114, the internal thread sleeve 114 penetrates the center plate 802 and is fixedly connected thereto, and the fixed sleeve 107 penetrates the internal thread sleeve 114 and is threadedly connected thereto;

[0056] When the upper end surface of the fixed plate 106 contacts the lower end surface of the center plate 802 , the feed opening 115 and the loading opening 301 are aligned with each other.

[0057] Preferably, the lifting component is preferably configured as an internal threaded sleeve 114. Specifically, the inner side of the internal threaded sleeve 114 is threadedly connected to the fixed sleeve 107. When the threaded column 105 rotates, since the fixed disk 106 and the limit ring 1 themselves have a certain weight, and the threaded connection itself has friction, when the threaded column 105 rotates in the initial state, it rotates relative to the fixed sleeve 107, so that the threaded column 105 drives the sorting disk 102 to rotate and descend until the sorting disk 102 is pressed down on the upper side of the silicon steel sheet body 6, and the silicon steel sheet body 6 is supported by the baffle 103, so that the whole The sorting disk 102 presses the silicon steel sheet body 6 against the upper side of the baffle 103 and cannot continue to descend. If the threaded column 105 continues to rotate at this time, since the sorting disk 102 cannot continue to descend, when the rotation driving force is greater than the friction between the threaded connection between the internal threaded sleeve 114 and the fixed sleeve 107, the threaded column 105 directly drives the sorting disk 102, the silicon steel sheet body 6, the baffle 103, the limit ring 1 and the fixed sleeve 107 to rotate synchronously, that is, the threaded column 105 drives the fixed sleeve 107 to rotate, so that the fixed sleeve 107 rotates relative to the internal threaded sleeve 114. Similarly, through the threaded connection The fixing sleeve 107 drives the fixing plate 106 and the limiting ring 1 to rotate and descend as a whole, and the rotation direction is opposite to the movable direction of the sliding block 112, so that the spring telescopic rod 111 first contacts the rubber ring 113 and remains stationary, thereby expanding the baffles 103. At the same time, the limiting ring 1 also docks with the supporting ring 104, so that the silicon steel sheet body 6 falls. At this time, since the baffles 103 are expanded, the sorting plate 102 can continue to move downward. At this time, when the threaded column 105 continues to rotate, since the limiting ring 1 cannot continue to descend, the fixing sleeve 107 also remains stationary, then The threaded column 105 rotates relative to the fixed sleeve 107, thereby driving the sorting disk 102 to rotate and descend, thereby driving the silicon steel sheet body 6 to adjust its own angular position until it falls. In other words, the entire lowering of the limit ring 1 can be achieved only through the rotation of the threaded column 105, and the baffles 103 are also driven to expand with each other, and then the sorting disk 102 is driven to descend and rotate, thereby driving the silicon steel sheet body 6 to align and fall. The automation degree is high, and the whole process can be achieved only by the rotation of the threaded column 105, which saves costs, and does not require additional driver programs for control, and is highly practical.

[0058] When resetting is required, the threaded column 105 rotates in the opposite direction, causing the sorting disk 102 to rise and contact with the fixed disk 106. The threaded column 105 can drive the fixed disk 106, the limit ring 1 and the fixed sleeve 107 to rotate in the opposite direction. The fixed sleeve 107 rotates in the opposite direction relative to the internal threaded sleeve 114 to rise and reset. When the upper end surface of the fixed disk 106 contacts the lower end surface of the center plate 802, the feed port 115 and the loading port 301 are realigned with each other, and reloading can be carried out.

[0059] The welding part 4 also includes a limiting seat 402, which is fixed on the upper side of the support seat 8. A square sleeve 403 is slidably fitted between the limiting seats 402. The square sleeve 403 is sleeved on the outside of the welding gun 401. A circular ring is arranged on the middle side of the square sleeve 403, and a cam 404 is arranged on the lower side of the circular ring. A pair of spring telescopic rods 405 are arranged between the square sleeve 403 and the support seat 8.

[0060] Preferably, the cam 404 rotates to push the circular ring and the square sleeve 403 to move up and down, thereby driving the welding gun 401 to move up and down, thereby performing welding.

[0061] A through transverse groove is provided at the upper end of the support seat 8, and a central axis is provided on one side of the cam 404, which is rotatably connected to the through transverse groove. A number of cavities are provided on the inner side of the support seat 8, and a gear three 201 is fixedly connected to the lower end of the chassis 2, and a fan gear 202 is meshedly connected to one side of the gear three 201, and a bevel gear one 204 is fixedly connected to the lower end of the fan gear 202, and a bevel gear one 204 is meshedly connected to one side of the bevel gear one 203, and a rotating rod 205 is fixedly connected to one side of the bevel gear two 203, and one end of the rotating rod 205 is fixedly connected to a pulley one 206, and the upper end of the pulley one 206 is connected to a pulley two 207, the central axis passes through the pulley two 207 and is fixedly connected thereto, and the rotating rod 205 is driven to rotate by the motor assembly.

[0062] Preferably, the motor assembly drives the rotating rod 205 to rotate, and the rotating rod 205 drives the bevel gear 203 and the pulley 1 206 to rotate synchronously. The bevel gear 203 is meshed with the bevel gear 1 204, thereby driving the fan gear 202 to rotate, and the fan gear 202 is intermittently meshed with the gear 3 201, thereby driving the chassis 2 to rotate intermittently. At the same time, the pulley 1 206 drives the pulley 2 207 to rotate, and the pulley 2 207 drives the cam 404 to rotate, driving the welding gun 401 to move up and down. In other words, the rotation of the chassis 2 and the welding gun 401 can be synchronously realized through the rotation of the rotating rod 205. 401 is displaced up and down, so that the welding gun 401 is displaced up and down to weld a plurality of stacked silicon steel sheet bodies 6. Specifically, when the welding gun 401 moves from top to bottom, the silicon steel sheet body 6 is welded through the gap between the limiting vertical plates 101. After the welding is completed, the chassis 2 drives the silicon steel sheet body 6 to rotate 90 degrees intermittently. At the same time, the welding gun 401 is reset upward, and then the chassis 2 is fixed. The welding gun 401 then welds one side of the silicon steel sheet body 6 that remains stable after rotation, and so on, until all four sides of the silicon steel sheet body 6 are welded to achieve full fixation;

[0063] It is worth noting that in belt drive or chain drive, the transmission ratio can be changed by replacing the driving wheel and the driven wheel with different diameters, and in gear drive, the transmission ratio can be changed by replacing the driving gear and the driven gear with different numbers of teeth. Therefore, by setting the diameters of pulley 1 206 and pulley 2 207 to be different, and the numbers of teeth of bevel gear 1 204 and bevel gear 2 203 to be different, the transmission ratio can be adjusted to achieve that when gear 3 201 is meshed with fan gear 202, fan gear 202 drives chassis 2 to rotate 90 degrees, thereby adjusting the welding angle of silicon steel sheet body 6. At this time, pulley 2 207 rotates half a circle, and cam 404 drives welding gun 401 to reset from bottom to top. When gear 3 201 is not meshed with fan gear 202, chassis 2 and silicon steel sheet body 6 remain stable, and cam 404 drives welding gun 401 to perform welding from top to bottom, thereby achieving welding of the stable silicon steel sheet body 6 and improving welding stability.
