Description

Technical Field

[0001] The present invention relates to the technical field of welding processing, in particular to a component welding processing mechanism for motor manufacturing. Background Art

[0002] Friction stir welding is a solid-phase welding technology, especially suitable for welding light alloys. Compared with traditional fusion welding, friction stir welding is less likely to produce defects such as hydrogen holes, slag inclusions, thermal cracks, large deformation, etc. during the welding process, and can achieve the connection of difficult-to-weld materials. The high-speed rotating stirring head inserts the stirring needle into the workpiece to be welded. When the workpiece to be welded and the stirring head shoulder are in close contact, the stirring head moves relative to the workpiece along the welding direction. The intense friction between the stirring head and the workpiece causes the welding temperature to rise rapidly, and the metal in the weld area becomes thermoplastic. Under the traction, stirring and extrusion of the stirring needle and the shoulder, a dense and reliable weld is formed.

[0003] During the welding process of motor housing components, special fixtures are generally used to clamp and position them. When clamping motor housings of different sizes, it is necessary to replace unused fixtures, which is troublesome to operate. The positioning fixture is fixed to the workbench by bolts, and then the welding process is performed by a stirring welding mechanism.

[0021] Before welding by welding mechanism 2, it is necessary to position the motor housing 6 and place the motor housing 6 in the middle position on the bearing seat plate 4. Then, the support plate 802 is rotated and regulated by hand so that the positioning pressure column 905 contacts the outer wall of the motor housing 6. At the same time, the movable bearing block 703 is used in conjunction with the limiting movable groove 702 to make the positioning pressure column 905 move down along the side wall of the motor housing 6 until it contacts the housing convex edge 61 at the corresponding position on the outer wall of the motor housing 6. At this time, the housing convex edge 61 has a limiting blocking effect on the positioning pressure column 905; wherein the fixed plate body 701 in the welding positioning device is welded and fixedly set on the welding workbench 1, and the fixed plate body 701 is provided with a limiting movable groove 702, and the limiting movable groove 702 is slidably connected with a movable bearing block 703, and the top of the movable bearing block 703 is fixedly provided with a connecting protrusion 704, and the top of the connecting protrusion 704 is fixedly provided with a concave plate frame 705; the movable bearing block 70 3 is provided with a threaded through groove 706, and the threaded through groove 706 is threadedly connected with the positioning threaded column 707.

The concave plate frame 705 is connected to the regulating connector. The rotating connecting column 801 in the regulating connector is connected to the concave plate frame 705 through the connecting pin 803, and the side wall of the rotating connecting column 801 is fixed. A support plate 802 is provided, and a clamping assembly is provided at the other end of the support plate 802; a connecting strip 805 is fixedly provided on one side of the support plate 802, and a threaded hole body 806 is provided in the connecting strip 805, and the threaded hole body 806 is adapted to be threadedly connected with a locking screw 807, and an auxiliary knob 808 is fixedly provided at one end of the locking screw 807, and a locking slot 804 is provided on one side of the concave plate frame 705, and is equidistantly arranged in an arc shape, and one end of the locking screw 807 is adapted to be snapped into the locking slot 804.

[0022] After adjusting the position of the rear positioning pressure column 905, it is necessary to position the movable supporting block 703 and the support plate 802, that is, first rotate the positioning threaded column 707 by the auxiliary handle 708 so that one end of the positioning threaded column 707 is stuck in the positioning slot 709 at the corresponding position in the limiting movable groove 702, thereby realizing the position positioning of the movable supporting block 703; then rotate the locking screw 807 by the auxiliary knob 808 so that one end of the locking screw 807 is stuck in the locking groove 804 at the corresponding position on the side wall of the concave plate frame 705, thereby realizing the position positioning of the connecting strip 805, and the connecting strip 805 is fixedly connected to the support plate 802. The rotation of the support plate 802 will cause the connecting strip 805 to rotate. After the connecting strip 805 is positioned, the positioning work of the support plate 802 can be realized.

[0023] When the motor housing 6 is limited by the positioning pressure column 905, in order to further improve its limiting stability, an auxiliary rubber sleeve 1001 is sleeved on the outer wall of the positioning pressure column 905, which can, on the one hand, improve the contact friction effect of the positioning pressure column 905 on the motor housing 6, and on the other hand, provide a flexible contact effect to avoid the problem of clamping and extrusion damage, which has a positive effect on protecting the quality of the motor housing 6; wherein the Y-shaped support bar 901 in the clamping assembly is fixedly set at one end of the support plate 802, and the two ends of the Y-shaped support bar 901 are symmetrically fixed with a connector 902, and the end face of one end of the connector 902 is embedded with an auxiliary bearing 903, and the auxiliary bearing 903 is sleeved on the connecting plug shaft 904, and the connecting plug shaft 904 is fixed at one end of the positioning pressure column 905; the positioning pressure column 905 is symmetrically set in two groups, and the end face diameter of the positioning pressure column 905 is larger than the end face diameter of the connector 902; the positioning pressure column 905 05 is connected to the auxiliary structure, and the auxiliary rubber sleeve 1001 in the auxiliary structure is sleeved and fixedly set on the positioning pressure column 905, and the through-screw cavity 1002 is set in the positioning pressure column 905, and the through-screw cavity 1002 extends into the auxiliary rubber sleeve 1001; the through-screw cavity 1002 is adapted to be threadedly connected with the tightening thread column 1003, and one end of the tightening thread column 1003 is fixedly provided with a cylindrical handle 1004, and the tightening thread column 1003 is fixedly provided with the positioning pressure column 9 05 The two are provided with the same number of groups, that is, a clamping thread column 1003 is provided in a positioning pressure column 905; and a spherical connecting clamp 1005 is fixedly provided at one end of the clamping thread column 1003, and the spherical connecting clamp 1005 is adapted to be clamped with the connecting slot 1007, and the connecting slot 1007 is provided in the rubber pressure head 1006, and the rubber pressure head 1006 is set to be hemispherical, and the radius of the rubber pressure head 1006 is set equal to the end face radius of the clamping thread column 1003.

[0024] The present invention also provides a screw hole 1002 for the positioning pressure column 905 to be used in conjunction with the tightening thread column 1003, that is, the tightening thread column 1003 is rotated by the cylindrical handle 1004 so that the tightening thread column 1003 squeezes the side wall of the motor housing 6 or the angle formed by the motor housing 6 and the housing flange 61 until the tightening thread column 1003 is tightened; wherein a rubber pressure head 1006 is also provided at the extrusion end of the tightening thread column 1003, and the role of the rubber pressure head 1006 here is to protect the motor housing 6 when being squeezed by the tightening thread column 1003, and also to avoid extrusion damage; furthermore, the rubber pressure head 1006 and the tightening thread column 1003 are connected by the spherical connecting clamp 1005 and the connecting card slot 1007, that is, they are detachable and easy to disassemble and assemble, that is, they can be easily installed and disassembled in the later stage. It is more convenient to replace the spherical connecting clamp 1005; on the other hand, the spherical connecting clamp 1005 is adapted to be clamped with the connecting slot 1007, and the spherical connecting clamp 1005 is movable in the connecting slot 1007, that is, when the motor housing 6 or the angle between the motor housing 6 and the housing flange 61 is squeezed by the tightening thread column 1003, the rubber pressure head 1006 will contact the side wall of the motor housing 6 or the angle between the motor housing 6 and the housing flange 61, and after the contact, as the tightening thread column 1003 rotates, the tightening force of the rubber pressure head 1006 will be increased. As the tightening force increases, the rubber pressure head 1006 will be tightened and will no longer rotate with the rotation of the tightening thread column 1003, thereby reducing the friction damage caused by the rubber pressure head 1006 to the motor housing 6 or the housing flange 61, and at the same time, it will also reduce the loss of the rubber pressure head 1006 and improve its service life.

[0025] In order to further improve the clamping flexibility of the clamping threaded column 1003, the positioning pressure column 905 provided in this scheme is connected to the auxiliary bearing 903 through the connecting plug shaft 904 at its end, so that the positioning pressure column 905 can be rotated. The rotation of the positioning pressure column 905 can adjust the direction of the through-screw cavity 1002 provided therein, and the through-screw cavity 1002 is threadedly connected to the clamping threaded column 1003, so that the extrusion angle of the clamping threaded column 1003 can also be adjusted, which has better flexibility of use. After the motor housing 6 is clamped by the clamping threaded column 1003, the positioning work of the motor housing 6 can be completed, and then the welding process can be carried out through the welding mechanism 2.

[0026] This solution mainly positions and clamps the motor housing 6 by setting three sets of welding positioning devices on the bearing seat plate 4, and then welds the motor housing 6 through the set welding mechanism 2. The welding positioning device is used in conjunction with the movable bearing block 703, the fixed plate body 701 and the regulating connector and the clamping assembly, so that it has corresponding clamping and positioning capabilities for motor housings 6 of different specifications, and has excellent clamping and positioning capabilities. There is no need to replace other positioning fixtures for motor housings 6 of different specifications and sizes, which saves operation difficulty, and on this basis has good positioning stability, which has a positive effect on improving its welding processing efficiency.
