Description
Technical Field
[0001] This invention relates to the field of welding processing technology, and in particular to a welding processing mechanism for motor manufacturing components. Background Technology
[0002] Friction stir welding is a solid-state welding technique, particularly suitable for welding light alloys. Compared with traditional fusion welding, friction stir welding is less prone to defects such as hydrogen porosity, slag inclusions, hot cracks, and large deformation during the welding process, and it can also achieve the joining of difficult-to-weld materials. The high-speed rotating stirring head inserts the stirring pin into the workpiece to be welded. After the workpiece and the shoulder of the stirring head have made 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 zone exhibits a thermoplastic state. Under the traction, stirring, and extrusion of the stirring pin and the shoulder, a dense and reliable weld is formed.
[0003] In the welding process of motor housing components, special fixtures are generally used for clamping and positioning. When clamping motor housings of different sizes, different fixtures need to be changed, which is cumbersome. The positioning fixture is fixed to the worktable with bolts, and then welding is carried out by a stirring welding mechanism. In order to save the positioning operation of the motor housing, the existing method is to place the motor housing on the worktable and then use a screw to push the clamping plate to clamp the side wall of the motor housing. Although it has a certain degree of work flexibility, its stability needs to be improved.

Detailed Implementation
[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.
[0031] Example 1: Please refer to Figures 1-10 A welding processing mechanism for motor manufacturing parts includes a welding worktable 1 and a support leg 3 set at the bottom of the welding worktable 1. A welding mechanism 2 is set on the welding worktable 1. A bearing plate 4 is fixedly set on the welding worktable 1 by mounting bolts 5. A motor housing 6 is placed on the bearing plate 4. The motor housing 6 is positioned by a welding positioning device. Then, welding is performed by the welding mechanism 2. The welding positioning device is set on the welding worktable 1 and three sets are equidistantly arranged.
[0032] Before welding by the welding mechanism 2, the motor housing 6 needs to be positioned. The motor housing 6 is placed in the center of the support plate 4. Then, the support plate 802 is rotated manually to make the positioning pin 905 contact the outer wall of the motor housing 6. Simultaneously, the movable support block 703, in conjunction with the limiting groove 702, moves the positioning pin 905 down along the side wall of the motor housing 6 until it contacts the corresponding housing protrusion 61 on the outer wall of the motor housing 6. At this point, the housing protrusion 61 acts as a limiting stop for the positioning pin 905. The fixed plate 701 in the welding positioning device is fixedly mounted on the welding workbench 1, and the fixed plate 701 has a through-hole limiting groove 702. A movable support block 703 is slidably connected in the limiting groove 702, and a connecting protrusion 704 is fixedly mounted on the top of the movable support block 703. A concave plate frame 705 is fixedly mounted on the top of the connecting protrusion 704. A threaded groove 706 is provided through the 3rd section, and the threaded groove 706 is threadedly connected to the positioning threaded post 707. An auxiliary handle 708 is fixedly provided at one end of the positioning threaded post 707. The positioning slot 709 is provided in the limiting movable groove 702 and is arranged in a straight line at equal intervals. The concave plate frame 705 is connected to the regulating connector. The rotating connecting post 801 in the regulating connector and the concave plate frame 705 are connected by a connecting pin 803, and the side wall of the rotating connecting post 801 is fixedly provided with 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 806 is provided in the connecting strip 805. The threaded hole 806 is threadedly connected to the locking screw 807, and an auxiliary knob 808 is fixedly provided at one end of the locking screw 807. A locking slot 804 is provided on one side of the concave plate frame 705 and is equidistantly arranged in an arc shape. One end of the locking screw 807 is adapted to engage with the locking slot 804.
[0033] After adjusting the position of the positioning column 905, the movable bearing block 703 and the support plate 802 need to be positioned. First, the positioning threaded column 707 is rotated by the auxiliary handle 708, so that one end of the positioning threaded column 707 is engaged in the corresponding positioning slot 709 in the limiting movable groove 702, thus positioning the movable bearing block 703. Then, the locking screw 807 is rotated by the auxiliary knob 808, so that one end of the locking screw 807 is engaged in the corresponding locking slot 804 on the side wall of the concave plate frame 705, thus positioning the connecting strip 805. The connecting strip 805 is fixedly connected to the support plate 802. The rotation of the support plate 802 will rotate the connecting strip 805. After positioning the connecting strip 805, the positioning of the support plate 802 is completed.
[0034] When the positioning pressure column 905 limits the motor housing 6, 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. This not only increases the contact friction between the positioning pressure column 905 and the motor housing 6, but also provides a flexible contact, avoiding clamping and squeezing damage, thus playing a positive role in protecting the mass of the motor housing 6. The Y-shaped support bar 901 in the clamping assembly is fixedly installed at one end of the support plate 802, and connecting bodies 902 are symmetrically fixed at both ends of the Y-shaped support bar 901. An auxiliary bearing 903 is embedded in the end face of one end of the connecting body 902, and the auxiliary bearing 903 is sleeved on the connecting shaft 904, which is fixedly installed at one end of the positioning pressure column 905. Two sets of positioning pressure columns 905 are symmetrically arranged, and the end face diameter of the positioning pressure column 905 is larger than the end face diameter of the connecting body 902. 05 is connected to the auxiliary structure, and the auxiliary rubber sleeve 1001 in the auxiliary structure is sleeved and fixedly mounted on the positioning pressure post 905. The through screw cavity 1002 is set in the positioning pressure post 905 and extends into the auxiliary rubber sleeve 1001. The through screw cavity 1002 is threadedly connected to the clamping thread post 1003. One end of the clamping thread post 1003 is fixedly provided with a cylindrical handle 1004. The clamping thread post 1003 and the positioning pressure post 905 are connected. 05 Both are set with the same number of groups, that is, one clamping threaded column 1003 is set in one positioning pressure column 905; and one end of the clamping threaded column 1003 is fixedly set with a spherical connecting clip 1005, which is adapted to and snapped into the connecting groove 1007. The connecting groove 1007 is set in the rubber pressure head 1006, which is set as a hemispherical shape, and the radius of the rubber pressure head 1006 is set to be equal to the end face radius of the clamping threaded column 1003.
[0035] Furthermore, to further improve its positioning stability, this solution also incorporates a through-hole screw cavity 1002 in the positioning pressure column 905 to cooperate with the clamping threaded column 1003. Specifically, by rotating the clamping threaded column 1003 using the cylindrical handle 1004, the clamping threaded column 1003 presses against the side wall of the motor housing 6 or the angle formed by the motor housing 6 and the housing protrusion 61 until the clamping threaded column 1003 is tightened. A rubber pressure head 1006 is also provided at the pressing end of the clamping threaded column 1003. The rubber pressure head 1006 protects the motor housing 6 during the pressing process, preventing damage. Moreover, the rubber pressure head 1006 and the clamping threaded column 1003 are connected by a ball-shaped connecting clip 1005 and a connecting slot 1007, achieving both detachability and ease of assembly and disassembly, thus facilitating future adjustments. Replacing the spherical connector 1005 is relatively convenient. Furthermore, the spherical connector 1005 is compatible with the connector groove 1007 and can move within the groove. This means that when the motor housing 6 or the angle between the motor housing 6 and the housing protrusion 61 is pressed by the clamping thread 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 protrusion 61. After contact, as the clamping thread 1003 rotates, the clamping force of the rubber pressure head 1006 increases. With this increased clamping force, the rubber pressure head 1006 is compressed and will no longer rotate with the clamping thread 1003, thus reducing frictional damage to the motor housing 6 or the housing protrusion 61 caused by the rubber pressure head 1006. This also reduces wear and tear on the rubber pressure head 1006 and extends its service life.
[0036] To further improve the clamping flexibility of the threaded clamping post 1003, the positioning post 905 in this design is connected to the auxiliary bearing 903 via a connecting shaft 904 at its end. This allows the positioning post 905 to rotate, and the rotation of the positioning post 905 can adjust the direction of the through threaded cavity 1002. The through threaded cavity 1002 is threadedly connected to the threaded clamping post 1003, which allows for adjustment of the pressing angle of the threaded clamping post 1003, providing better flexibility. After the threaded clamping post 1003 clamps the motor housing 6, the positioning of the motor housing 6 is completed, and then welding is performed by the welding mechanism 2.
[0037] This solution mainly involves setting three sets of welding positioning devices on the bearing plate 4 to position and clamp the motor housing 6, and then using the welding mechanism 2 to perform welding on the motor housing 6. The welding positioning devices, through the coordinated use of the movable bearing block 703, the fixed plate 701, the control connector, and the clamping components, have corresponding clamping and positioning capabilities for motor housings 6 of different specifications, providing excellent clamping and positioning capabilities. For motor housings 6 of different sizes, there is no need to change other positioning fixtures, saving operational difficulty. Furthermore, it has good positioning stability, which has a positive effect on improving the efficiency of welding processing.
[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
