DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] See also Figure 1-5 A micro motor automatic welding mechanism in this embodiment includes a robotic arm 2 located on a workbench 1 and a double-station positioning mechanism located on the workbench 1, wherein there are two robotic arms 2 in total, and welding guns are provided at the ends of the two robotic arms 2 for welding the micro motor.

[0027] In this embodiment, the double-station positioning mechanism includes a carrier plate 3 fixedly mounted on the top of the workbench 1, a cylinder 5 mounted on the workbench 1, a mounting plate 4 perpendicular to the carrier plate 3 fixedly mounted on the top of the carrier plate 3, and the cylinder 5 fixedly connected to the mounting plate 4.

[0028] It should be noted that the double-station positioning mechanism also includes a first bow block 6 and a second bow block 10 arranged on the power end of the cylinder 5, and a first rack 61 is vertically fixedly connected to one end of the first bow block 6, and a slider 62 is fixedly connected to the other end of the first bow block 6, wherein the first rack 61 is fixedly connected to the power end of the cylinder 5.

[0029] Specifically, two connecting rods are fixedly mounted on the power end of the cylinder 5 and are staggered upward and leftward and rightward. The two connecting rods are connected to the first bow block 6 and the second bow block 10 respectively.

[0030] In a specific implementation, the cylinder 5 pulls the first rack 61 to move, so that the first bow block 6 and the slider 62 can slide and change positions synchronously.

[0031] It is additionally explained that the first arch block 6 and the second arch block 10 have the same structure and are symmetrically arranged on the carrier plate 3 , and the first arch block 6 and the second arch block 10 are arranged in a vertically adjacent manner.

[0032] The top of the carrier plate 3 in this embodiment is rotatably mounted with a gear 11 , and the first rack 61 is tooth-engaged with the gear 11 , so that the gear 11 can be driven to rotate by the movement of the first rack 61 .

[0033] In this embodiment, a slide bar 8 is fixedly installed on the mounting plate 4, and a slider 62 is slidably connected to the slide bar 8. A first auxiliary block 7 is slidably installed on the outside of the slide bar 8. A second rack 71 is fixedly installed on one side of the first auxiliary block 7 facing the gear 11. The second rack 71 is toothedly meshed with the gear 11. The gear 11 rotates to make the first auxiliary block 7 move.

[0034] The gear 11 includes two sections connected to each other in an upper and lower rotation manner, and the first rack 61 and the second rack 71 are meshed with the upper section of the gear 11 .

[0035] It should be noted that the first rack 61 and the second rack 71 are symmetrically located on both sides of the gear 11. Therefore, when the gear 11 rotates, the movement directions of the first bow block 6 and the first auxiliary block 7 can be opposite, and the first bow block 6 and the first auxiliary block 7 can be clamped close to each other.

[0036] In this embodiment, a clamp 12 for clamping the micro motor is fixedly mounted on the first arch block 6 and the first auxiliary block 7 , and the two clamps 12 can be brought close to each other for clamping by the cylinder 5 .

[0037] Preferably, a slide groove 13 corresponding to the slide bar 8 is provided at the bottom of the first arch block 6 and the first auxiliary block 7 , and the slide bar 8 is slidably connected relative to the slide groove 13 , so that the clamping stability of the clamp 12 is improved.

[0038] It should be noted that a second auxiliary block 9 symmetrical to the first auxiliary block 7 is also tooth-engaged on one side of the gear 11, wherein the first arch block 6 and the first auxiliary block 7 are symmetrically arranged on both sides of the gear 11 relative to the second arch block 10 and the second auxiliary block 9, and fit together up and down;

[0039] Furthermore, the two cylinders 5 are offset up and down, so that the cylinders 5 can be connected relative to the offset first arch block 6 and the second arch block 10 .

[0040] In this embodiment, a swing groove 14 is opened on the inner side of the clamp 12, a connecting shaft 15 is rotatably installed inside the clamp 12, a clamping block 16 is rotatably installed outside the connecting shaft 15, and a spring 17 is connected between the clamping block 16 and the inner wall of the swing groove 14. The spring 17 pushes the clamping block 16, so that the clamping block 16 has adaptive ability to fit the micro motor for clamping.

[0041] The working principle of the above embodiment is:

[0042] By loading the micro motor onto the fixture 12 between the first bow block 6 and the first auxiliary block 7, and between the second bow block 10 and the second auxiliary block 9, the cylinder 5 is controlled to drive the connected first rack 61 and the second bow block 10 to approach the mounting plate 4. At this time, the first rack 61 drives the upper part of the gear 11 to rotate through tooth meshing, and at the same time, the first auxiliary block 7 is driven to move in the opposite direction of the movement of the first bow block 6 under the rotation of the gear 11, so that the fixture 12 on one side completes the clamping of the micro motor, and the second bow block 10 pulled by the cylinder 5 drives the lower part of the gear 11 to rotate through tooth meshing, and at the same time, the second auxiliary block 9 is driven to move in the opposite direction of the movement of the second bow block 10 under the rotation of the gear 11, so that the fixture 12 on the other side completes the clamping of the micro motor, thereby realizing double-station positioning.
