Description

Technical Field

[0001] The invention belongs to the technical field of shaded-pole motor production, and in particular relates to welding equipment for motor processing. Background Art

[0002] The shaded pole motor, also known as the shaded pole motor, is a type of unidirectional AC motor. It usually uses a cage-type skewed slot cast aluminum rotor. The stator assembly consists of an iron core and main and auxiliary windings. The auxiliary winding is the short-circuit ring, and its function is to generate magnetic potential and form a rotating magnetic field in the air gap. The rotor consists of an iron core and squirrel cage bars. The squirrel cage bars are the conductors of the rotor windings. Their function is to generate induced electromotive force when it cuts the rotating magnetic field of the air gap, forming induced current and electromagnetic torque, thereby realizing the conversion of electrical energy and functional energy.

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0040] like Figures 1 to 5 As shown in the figure, it is a structural diagram of a welding device for motor processing provided by an embodiment of the present invention, comprising a fixed disk 1, a shaded-pole motor housing 2, an inner ring 4, an axial driving mechanism 100, a unidirectional intermittent motion mechanism 200, a circumferential adjustment mechanism 300 and a double-sided welding mechanism 400; the shaded-pole motor housing 2 is rotatably mounted on the fixed disk 1, and a plurality of heat dissipation ribs 3 are evenly arranged on the outer side of the shaded-pole motor housing 2, and grooves for embedding the heat dissipation ribs 3 can be provided on the outer side of the shaded-pole motor housing 2 as needed; the inner ring 4 is arranged in parallel with the fixed disk 1, and an axial driving mechanism 100 is rotatably mounted on the outer side of the inner ring 4; the axial driving mechanism 100 is arranged on the fixed disk 1 and the inner ring 4, and when the axial driving mechanism 100 is working The distance between the inner ring 4 and the fixed disk 1 is dynamically adjusted under normal conditions; the one-way intermittent motion mechanism 200 is installed on the shaded-pole motor housing 2 and the driving gear 6 in the axial driving mechanism 100, so that when the driving gear 6 rotates, the shaded-pole motor housing 2 is driven to rotate through the arranged one-way intermittent motion mechanism 200; the circumferential adjustment mechanism 300 is slidably installed on the positioning column 10 in the axial driving mechanism 100, and the circumferential adjustment mechanism 300 moves synchronously with the inner ring 4, and pushes the outer ring 5 to deflect along the inner ring 4 when working; the double-sided welding mechanism 400 is installed on the inner side of the inner ring 4, and one end of the double-sided welding mechanism 400 is hinged to the side of the outer ring 5, so as to adjust the welding position when the outer ring 5 deflects along the inner ring 4.

[0041] In one example of the present invention, the welding module 28 can be a laser welding or contact welding unit in actual use. The end face of the welding module 28 is fixedly connected to the guide rod 24, and the welding module 28 is electrically connected to an external controller. Under the drive of the controller, the welding module 28 welds both sides of the heat dissipation rib 3 at the same time during operation, which can effectively avoid uneven distribution of unilateral welding stress, resulting in deflection of the position of the heat dissipation rib 3, thereby improving the welding accuracy.

[0042] like Figure 1 As shown, as a preferred embodiment of the present invention, the axial drive mechanism 100 includes a driving gear 6, an incomplete gear 7, a driving screw 8, an elastic paddle 9 and a positioning column 10;

[0043] There are multiple positioning posts 10, which are slidably connected to the inner ring 4 and driven by a driving screw 8 installed on the fixed plate 1;

[0044] The driving screw 8 is rotatably mounted on the fixed plate 1, and one end of the driving screw 8 is connected to an elastic paddle 9 mounted on the fixed plate 1;

[0045] An incomplete gear 7 is installed at the other end of the driving screw 8, and a driving gear 6 meshing with the incomplete gear 7 is independently arranged on the outside.

[0046] In one embodiment of the present invention, when the external motor is working, it can drive the driving gear 6 to rotate. Since the driving gear 6 is meshed with the incomplete gear 7, the incomplete gear 7 and the driving screw 8 can be driven to rotate along the fixed disk 1 when the driving gear 6 rotates. The driving screw 8 pushes the inner ring 4 and the outer ring 5 to slide along the positioning column 10. During this process, the elastic paddle 9 is elastically deformed by the force, and when the driving gear 6 is disengaged from the incomplete gear 7, the elastic paddle 9 controls the driving screw 8 to reverse, so that the inner ring 4 and the outer ring 5 move in the opposite direction along the positioning column 10.

[0047] like Figure 1 and Figure 2 As shown, as another preferred embodiment of the present invention, the unidirectional intermittent motion mechanism 200 includes a movable disk 11, a driving disk 12, a pulley 13, a synchronous belt 14, a shifting post 15 and a groove 16;

[0048] The movable disk 11 is installed at the end of the shaded-pole motor housing 2, and a plurality of grooves 16 are formed on the movable disk 11;

[0049] A driving disk 12 is arranged on the side of the movable disk 11, and the driving disk 12 and the driving gear 6 are located in the same plane, and pulleys 13 are installed on the shafts of the driving gear 6 and the driving disk 12, and adjacent pulleys 13 are connected by a synchronous belt 14;

[0050] A shifting post 15 is eccentrically arranged on the driving disc 12. The shifting post 15 slides along the groove 16 in a rotating state to shift the movable disc 11 and the shaded-pole motor housing 2 to rotate.

[0051] In one example of the present invention, the shafts of the driving gear 6 and the driving disk 12 are supported by an external support frame, and the shaft on the driving gear 6 is connected to the motor arranged on the external support frame as a driving shaft; when the driving gear 6 rotates along the support frame driven by the motor, the driving gear 6 drives the pulley 13 at the corresponding position to rotate, and drives the driving disk 12 and the pulley 13 thereon to rotate through the arranged synchronous belt 14, and the driving disk 12 also drives the shifting post 15 to slide along the groove 16, and the movable disk 11 is forced to drive the shaded pole motor housing 2 to rotate, so that when the driving gear 6 rotates continuously, the movable disk 11 and the shaded pole motor housing 2 can make directional intermittent rotations.

[0052] like Figure 3 and Figure 4 As shown, as another preferred embodiment of the present invention, the circumferential adjustment mechanism 300 includes a side plate 17, a tool box 18, a gear 19 and an external tooth portion 20;

[0053] The side plate 17 is slidably mounted on the positioning column 10, and the side surface of the side plate 17 is fixedly connected to the inner ring 4;

[0054] A tool box 18 is fixedly mounted on the side of the side plate 17, and a gear 19 is rotatably arranged on the tool box 18, and the gear 19 is driven by a built-in micro motor;

[0055] An outer portion of the outer ring 5 is partially provided with an outer tooth portion 20 , which meshes with the gear 19 so as to push the outer ring 5 to slide along the inner ring 4 when the gear 19 rotates.

[0056] In one embodiment of the present invention, the micro motor is a forward and reverse motor. When the inner ring 4 slides along the positioning column 10, the inner ring 4, the side plate 17 and the tool box 18 slide synchronously along the positioning column 10. When the welding distance needs to be adjusted, the built-in micro motor in the tool box 18 drives the gear 19 to rotate. Since the gear 19 is engaged with the outer tooth portion 20, it can drive the outer tooth portion 20 and the outer ring 5 to slide along the inner ring 4.

[0057] like Figure 3 and Figure 5 As shown, as another preferred embodiment of the present invention, the double-sided welding mechanism 400 includes a guide sleeve 21, a connecting rod 1 22, an inclined rod 23, a guide rod 24, a connecting rod 25, a fixed pile 26 and a movable rod 27;

[0058] The guide sleeves 21 are arranged in pairs on the inner side of the inner ring 4, a connecting rod 22 is arranged between the two guide sleeves 21, an oblique rod 23 is fixedly installed on the outer side of the guide sleeves 21, and the end of the oblique rod 23 is fixedly connected to the inner side of the inner ring 4;

[0059] Wherein, guide rods 24 are slidably mounted on the two guide sleeves 21, and connecting rods 25 are mounted on the inner sides of the two guide rods 24;

[0060] The second connecting rod 25 is fixedly connected with a fixing pile 26 , and an end of the fixing pile 26 is installed with a movable rod 27 , and the end of the movable rod 27 is hinged to the side surface of the outer ring 5 .

[0061] In one embodiment of the present invention, when the outer ring 5 slides along the inner ring 4, the outer ring 5 pushes the movable rods 27 at multiple positions to deflect at the same frequency, and the movable rods 27 push the connecting rod 25 and the guide rod 24 to slide synchronously along the guide sleeve 21 in turn through the fixed pile 26, and the two welding modules 28 move synchronously with the guide rods 24 at the corresponding positions, so that after the heat dissipation rib 3 is placed on the shaded-pole motor housing 2, synchronous welding can be performed from both sides of the heat dissipation rib 3.

[0062] In summary, the shaded-pole motor housing 2 is mounted on the fixed disk 1 and the external support frame. After the heat dissipation rib 3 is placed on the shaded-pole motor housing 2, the built-in micro motor in the tool box 18 drives the gear 19 to rotate. Since the gear 19 is meshed with the outer tooth portion 20, the outer tooth portion 20 and the outer ring 5 can be driven to slide along the inner ring 4. The outer ring 5 pushes the movable rods 27 at multiple positions to deflect at the same frequency. The movable rod 27 pushes the connecting rod 25 and the guide rod 24 to slide synchronously along the guide sleeve 21 in turn through the fixed pile 26. The two welding modules 28 move synchronously with the guide rods 24 at the corresponding positions, so as to facilitate Synchronous welding is performed from both sides of the heat dissipation rib 3. After the heat dissipation rib 3 at this position is welded, when the driving gear 6 rotates along the support frame under the drive of the motor, the driving gear 6 drives the pulley 13 at the corresponding position to rotate, and drives the driving disc 12 and the pulley 13 thereon to rotate through the set synchronous belt 14. The driving disc 12 also drives the lever 15 to slide along the groove 16. The movable disc 11 is forced to drive the shaded-pole motor housing 2 to rotate, so that when the driving gear 6 rotates continuously, the movable disc 11 and the shaded-pole motor housing 2 perform directional intermittent rotation. Since the driving gear 6 is meshed with the incomplete gear 7, When the driving gear 6 rotates, the incomplete gear 7 and the driving screw 8 can be driven to rotate along the fixed plate 1, and the driving screw 8 pushes the inner ring 4 and the outer ring 5 to slide along the positioning column 10. In this process, the elastic paddle 9 is elastically deformed by force, and when the driving gear 6 is out of mesh with the incomplete gear 7, the driving screw 8 is controlled by the elastic paddle 9 to reverse, so that the inner ring 4 and the outer ring 5 move in the opposite direction along the positioning column 10. Finally, when the shaded-pole motor housing 2 stops rotating, the welding module 28 moves along the welding point between the shaded-pole motor housing 2 and the heat dissipation rib 3. After block 28 is separated from the heat dissipation rib 3, the next heat dissipation rib 3 to be welded rotates to the welding station and stops moving, and the welding module 28 moves in the opposite direction along the welding point between the shaded-pole motor housing 2 and the heat dissipation rib 3; therefore, the welding equipment can improve the welding efficiency several times when the heat dissipation rib 3 is placed in the shaded-pole motor housing 2 in sequence, and can accurately control the welding distance during the welding process to ensure the consistency of the welding quality. At the same time, through the double-sided synchronous welding method, it can effectively avoid the uneven distribution of welding stress on one side, which causes the deflection or warping of the heat dissipation rib 3, thereby improving the welding accuracy.

[0063] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
