Description

Technical Field

[0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to stator welding equipment for a motor. Background Art

[0002] In the manufacture of motors, the more important structures are the stator and the rotor. The stator is a stationary part of the motor. It can generate a rotating magnetic field as a whole and interact with the rotor to make it rotate. The stator is generally assembled by a motor housing, a stator core and a stator winding. The stator winding is a conductive coil wound around the stator core, and the conductive copper wire will eventually be connected to the external terminal through an external wire.

[0003] In the manufacture of high-performance or industrial servo motors, external wires and conductive copper wires are generally connected by welding to ensure electrical contact and mechanical stability between the two. However, before this, the two copper wires are usually twisted together manually and finally welded at the twisted ends. Since the copper wires are in a loose state, the manual twisting method may cause the two copper wires to not be well merged, which in turn reduces the subsequent welding effect and may also cause abnormalities in the detection work.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 9 As shown, the present invention provides a stator welding device for a motor, comprising a support assembly 1, and further comprising:

[0036] A driving assembly 2 disposed inside the supporting assembly 1;

[0037] The support assembly 1 comprises a housing 11;

[0038] A merging component 3 movably installed inside the supporting component 1;

[0039] The merging component 3 includes a positioning ring 31 movably mounted inside the shell 11, a positioning tube 32 is fixedly mounted on the top of the positioning ring 31, a transfer box 33 and an active ring 30 are respectively mounted on bearings at both ends of the bottom of the positioning tube 32, the active ring 30 is transmission-connected to the transfer box 33 through a chain 39, the positioning tube 32 is connected to the transfer box 33, a support ring 35 is movably mounted on the bottom of the positioning ring 31, two arc-shaped telescopic rods 34 are connected to the outer periphery of the transfer box 33 at equal angles in an annular direction, and the fixed ends of each arc-shaped telescopic rod 34 are fixedly connected to the support ring 35 through a limiting rod 2 310, a plurality of pressure plates 36 are hingedly connected to the bottom of the support ring 35 at equal angles in annular direction, and the outer side of each pressure plate 36 is elastically hinged to the support ring 35 through a spring sheet 1 37, and a plurality of limiting rods 1 38 that contact the outer side of each pressure plate 36 are arranged at equal angles in annular direction on the outer side of the positioning ring 31;

[0040] The driving assembly 2 is used to drive the positioning ring 31 to rise and simultaneously inject gas into the interior of the positioning tube 32. The driving assembly 2 is used to drive the active ring 30 to rotate;

[0041] A positioning component 4 is arranged inside the supporting component 1 and below the merging component 3;

[0042] The positioning component 4 is used to limit the positions of the external wires and the conductive copper wires.

[0043] Adopting the above scheme: when the external wire and the conductive copper wire need to be connected, the external wire and the conductive copper wire are first fixed in position by the positioning component 4 respectively, and then the external wire and the conductive copper wire are passed through the positioning ring 31 and are respectively located on one side of the bending of the two arc-shaped telescopic rods 34, and finally the active ring 30 is driven to rotate by the driving component 2. At the same time, the driving component 2 will also drive the positioning ring 31 and other structures in the merging component 3 thereon to rise;

[0044] It should be noted that the active ring 30 drives the transfer box 33 to rotate through the chain 39, and the transfer box 33 drives the two arc-shaped telescopic rods 34 to revolve around the center point of the transfer box 33, and the direction of rotation is located on the side where the arc-shaped telescopic rods 34 are bent. The driving component 2 will also inject gas into the interior of the positioning tube 32 at the same time. The gas enters the interior of the two arc-shaped telescopic rods 34 through the positioning tube 32 and the transfer box 33, and the movable end thereof will extend outward until the arc-shaped telescopic rods 34 are a full circle, thereby separating the external wire and the conductive copper wire into two separate copper wires;

[0045] Since the external wire and the conductive copper wire are fixed by the positioning assembly 4 respectively, the external wire and the conductive copper wire will be twisted together during the rotation of the two arc-shaped telescopic rods 34 to form a new copper wire;

[0046] Since the arc-shaped telescopic rod 34 is also fixedly connected to the support ring 35 through the second limiting rod 310, the support ring 35 will rotate synchronously, while the positioning ring 31 can only move longitudinally, and the limiting rod 1 38 thereon will not rotate. Figure 6 As shown in the figure, the pressure plate 36 and the enlarged limiting rod 1 38, during the process of the support ring 35 driving the pressure plate 36 to rotate, the limiting rod 1 38 will first contact the inclined surface of the pressure plate 36 and gradually contact the arc surface outside thereof. Since the limiting rod 1 38 is fixed in position, it will gradually squeeze the pressure plate 36, so that it can press the twisted external wire and the conductive copper wire, so that the two are more closely connected, which reduces the operator's manual twisting of the external wire and the conductive copper wire, and also makes the subsequent welding of the two more firmly;

[0047] Before twisting the two copper wires through the arc-shaped telescopic rod 34, each copper wire needs to be slightly twisted three to five times separately, so that the loose copper wires can be combined together. Similarly, each copper wire can completely fit the curved side of the arc-shaped telescopic rod 34. During the rotation of the two arc-shaped telescopic rods 34, the two loose copper wires will not be stuck at the connection between the arc-shaped telescopic rod 34 and the support ring 35. After the arc-shaped telescopic rod 34 gradually extends into a complete circle, the two copper wires can be located inside the two arc-shaped telescopic rods 34, so as to better twist the external wires and the conductive copper wires.

[0048] It should be noted again that the outside of the bellows 23 can also be connected to an additional air supply device. When the resistance to the extension of the arc-shaped telescopic rod 34 is too large, the air supply device can be started and air can be injected into the bellows 23 to increase the air pressure inside. Similarly, the air supply device can also ensure that after the arc-shaped telescopic rod 34 is extended, the copper wire will not be over-contracted and loosened, thereby ensuring the stability of the device.

[0049] The length of the external wire and the conductive copper wire inside the housing 11 cannot exceed the highest rising height of the positioning ring 31, otherwise the twisting work of the external wire and the conductive copper wire will not be completed.

[0050] like Figure 5 and Figure 6 As shown, the pressure plate 36 is in an arc shape, and the positioning ring 31 pulls the pressure plate 36 through the spring sheet 37 to always extend outward and contact with the limit rod 38. The number of pressure plates 36, spring sheets 37 and limit rods 38 is equal and they are distributed on the support ring 35 at equal angles in the annular direction.

[0051] With the above solution, the arc surface of the outer side of the pressure plate 36 can be better squeezed by the limit rod 38, and similarly, the arc surface of the inner wall of the pressure plate 36 can also well contact the outer periphery of the twisted external wire and the conductive copper wire, thereby making the external wire and the conductive copper wire twisted more tightly.

[0052] It should be noted that the number of pressure plates 36, spring sheets 37 and limit rods 38 is not limited, but each pressure plate 36, spring sheet 37 and limit rod 38 needs to be arranged in a circular shape with equal angles to facilitate pressing the copper wire.

[0053] like Figures 1 to 4 As shown, the driving assembly 2 includes a motor 21 fixedly mounted on the top of the housing 11, the output shaft of the motor 21 is transmission-connected to the positioning ring 31 via a threaded rod 22, two limiting grooves 25 for the movement of the active ring 30 are symmetrically provided on the outer circumference of the threaded rod 22, a bellows 23 is fixedly mounted on the top of the positioning ring 31, and the bellows 23 is connected to the positioning tube 32 via an air pipe 24.

[0054] The threaded rod 22 of the limiting groove 25 is bearing-mounted on the inner wall of the housing 11 , and the active ring 30 is clamped in the inner part of the limiting groove 25 .

[0055] Adopting the above scheme: when the device needs to work, the motor 21 is started, and the motor 21 drives the threaded rod 22 to rotate. However, since the active ring 30 moves inside the limiting groove 25, the threaded rod 22 will synchronously drive the active ring 30 to rotate, and since the positioning ring 31 can only move vertically on the inner wall of the shell 11, the threaded rod 22 will also drive the positioning ring 31 to rise through the threaded groove thereon. At this time, the external wire and the conductive copper wire can be twisted and raised at the same time, so that the external wire and the conductive copper wire will not be twisted in the same place and cause damage to the copper wire.

[0056] like Figure 2 The bellows 23 shown in the figure has its bottom fixed on the positioning ring 31 and its top connected to the bottom of the motor, and the motor 21 is fixedly installed on the housing 11. Therefore, during the rising process of the positioning ring 31, the bottom of the bellows 23 is squeezed by the motor 21, and the air inside the bellows 23 enters the interior of the positioning tube 32 through the air pipe 24, so that the two arc-shaped telescopic rods 34 can be smoothly extended and limit the positions of the external wires and the conductive copper wires, further improving the working efficiency.

[0057] like Figures 1 to 3 , Figure 7 and Figure 8 As shown, the support assembly 1 also includes a protective ring 13 hinged to the side of the shell 11, the hinge between the shell 11 and the protective ring 13 is connected through a rubber pad 12, and the outer side of the shell 11 is clamped on the protective ring 13 through a spring telescopic rod 14.

[0058] The inner wall of the shell 11 and the inner wall of the protective ring 13 are semicircular and have the same radius. The shell 11 and the protective ring 13 are combined into a circle. The bottom of the movable end of the spring telescopic rod 14 is inserted into the top of the protective ring 13 and the movable end of the spring telescopic rod 14 is fixed with a metal plate.

[0059] The above scheme is adopted: the protective ring 13 is folded to merge into a full circle with the shell 11, and the position of the protective ring 13 is limited by the spring telescopic rod 14 to prevent the external wire and the conductive copper wire from moving outward during the twisting process, and the rubber pad 12 will prevent the external wire and the conductive copper wire from being stuck at the hinge between the protective ring 13 and the shell 11 and causing damage to the device and the copper wire. When the device completes the work, the merging component 3 will be completely separated from the external wire and the conductive copper wire. By moving the metal sheet at the movable end of the spring telescopic rod 14, the movable end can be separated from the protective ring 13, so as to facilitate the external wire and the conductive copper wire to be separated from the device, thereby improving the convenience of use.

[0060] like Figure 1 , Figure 2 and Figures 7 to 9 As shown, the positioning assembly 4 includes a positioner 41 fixedly mounted on the inner wall of the shell 11, a tooth plate 42 is movably mounted in the middle of the positioner 41, a bidirectional arc spring telescopic rod 43 is fixedly mounted on the outer side of the tooth plate 42, the inner wall of the positioner 41 is elastically connected to the bidirectional arc spring telescopic rod 43 through a tension spring 44, an extension rod 46 is installed on the internal bearing of the positioner 41, and the two ends of the extension rod 46 are respectively transmission-connected with a knob 47 and a gear 45.

[0061] There are two tooth plates 42 and two-way arc spring telescopic rods 43 and they are staggered on the positioner 41 . Both tooth plates 42 are engaged with the gear 45 . The extension rod 46 passes through the outside of the shell 11 and the knob 47 is located outside the shell 11 .

[0062] The positioning assembly 4 further includes a ratchet 48 which is transmission-connected to the outer periphery of the extension rod 46 . The outer periphery of the housing 11 is elastically connected to a tooth plate 49 via a spring sheet 40 . The tooth plate 49 meshes with the ratchet 48 .

[0063] Adopting the above scheme: when the shell 11 and the protective ring 13 are combined into a full circle and are in a fixed state, the external wire and the conductive copper wire can be respectively passed through the two bidirectional arc spring telescopic rods 43, the protective ring 13 and the inner wall of the shell 11, and the knob 47 is rotated to drive the gear 45 to rotate through the extension rod 46, and the gear 45 forces the two tension springs 44 and the bidirectional arc spring telescopic rod 43 to move outward, and the two ends of the bidirectional arc spring telescopic rod 43 contact the inner wall of the shell 11 and the protective ring 13, and gradually shrink the two ends of the bidirectional arc spring telescopic rod 43, so as to clamp the external wire and the conductive copper wire respectively by combining the shell 11 and the protective ring 13, so that during the twisting process of the combined component 3, the external wire and the conductive copper wire will not be excessively pulled and damaged;

[0064] By manually rotating the knob 47, the two bidirectional arc spring telescopic rods 43, the housing 11 and the protective ring 13 are adjusted to clamp the external wire and the conductive copper wire, so that the clamping pressure can be manually adjusted to adapt to external wires and conductive copper wires of different thicknesses, and to prevent the two from being clamped;

[0065] The second spring sheet 40 will always press the second tooth plate 49 to engage with the ratchet 48, and the teeth on the ratchet 48 and the second tooth plate 49 are in an inclined state, which makes the knob 47 only able to rotate in one direction, thereby preventing the elastic force of the bidirectional arc spring telescopic rod 43 and the tension spring 44 from retracting, further improving the fixing effect of the positioning assembly 4;

[0066] When the bidirectional arc spring telescopic rod 43 no longer needs to clamp the external wire and the conductive copper wire, the tooth plate 2 49 can be lifted up, which no longer limits the position of the ratchet 48. The elasticity of the bidirectional arc spring telescopic rod 43 and the tension of the tension spring 44 enable the bidirectional arc spring telescopic rod 43 to return to the original position faster, thereby improving the convenience of using the positioning component 4.

[0067] The working principle and use process of the present invention:

[0068] Fold the protective ring 13 to make it merge into a full circle with the housing 11, and limit the position of the protective ring 13 by the spring telescopic rod 14. The rubber pad 12 will prevent the external wires and the conductive copper wires from being stuck at the hinge between the protective ring 13 and the housing 11.

[0069] The external wire and the conductive copper wire are passed through the two bidirectional arc spring telescopic rods 43, the protective ring 13 and the inner wall of the housing 11 respectively. By rotating the knob 47, the gear 45 is driven to rotate through the extension rod 46. The gear 45 forces the two tension springs 44 and the bidirectional arc spring telescopic rod 43 to move outward. The two ends of the bidirectional arc spring telescopic rod 43 contact the inner walls of the housing 11 and the protective ring 13, and gradually shrink the two ends of the bidirectional arc spring telescopic rod 43, so as to clamp the external wire and the conductive copper wire respectively with the housing 11 and the protective ring 13. The spring sheet 2 40 always presses the tooth plate 2 49 to mesh with the ratchet 48, and the gear 45 can only rotate in one direction.

[0070] The external wire and the conductive copper wire are passed through the positioning ring 31 and are respectively located on one side of the bending of the two arc-shaped telescopic rods 34, and the motor 21 is started. The motor 21 drives the threaded rod 22 to rotate. However, since the active ring 30 moves inside the limiting groove 25, the threaded rod 22 will synchronously drive the active ring 30 to rotate. Moreover, since the positioning ring 31 can only move vertically on the inner wall of the shell 11, the threaded rod 22 will also drive the positioning ring 31 to rise through the threaded groove thereon. During the rising process of the positioning ring 31, the bottom of the motor 21 squeezes the bellows 23, so that the air inside the bellows 23 enters the interior of the positioning tube 32 through the air pipe 24;

[0071] The active ring 30 drives the transfer box 33 to rotate through the chain 39, and the transfer box 33 drives the two arc-shaped telescopic rods 34 to revolve around the center point of the transfer box 33. The gas enters the interior of the two arc-shaped telescopic rods 34 through the positioning tube 32 and the transfer box 33, and the movable ends thereof will extend outward until the arc-shaped telescopic rods 34 form a full circle, thereby separating the external wire and the conductive copper wire into two separate copper wires. During the rotation of the two arc-shaped telescopic rods 34, the external wire and the conductive copper wire will be twisted together to form a new copper wire.

[0072] The support ring 35 rotates synchronously, while the positioning ring 31 can only move longitudinally, and the limit rod 38 thereon will not rotate. In the process of the support ring 35 driving the pressure plate 36 to rotate, the limit rod 38 will preferentially contact the inclined surface of the pressure plate 36 and gradually contact the arc surface on the outside thereof. Since the position of the limit rod 38 is fixed, it will gradually squeeze the pressure plate 36 so that it can press the twisted external wires and the conductive copper wires.
