Technical Field

[0001] The present invention relates to the technical field of turning, and in particular to turning equipment for processing a collector ring and a turning method thereof. Background Art

[0002] The manufacture of collector rings usually requires turning, especially the metal conductive ring part. Turning is a key process to ensure its precision, surface finish and conductive performance. During the production process of collector rings, the inner and outer walls of the tubular parts to be turned need to be turned. Through the search of existing technologies, it was found that the Chinese patent with announcement number CN220462237U discloses a piston ring turning device, which can simultaneously meet the inner and outer turning of the piston ring by combining the inner and outer clamping grooves with the fastening components.

[0003] However, it is worth considering that when the turning machine tool is turning the tubular parts to be turned, the tubular parts to be turned are generally placed horizontally on one side of the fixture.

The elastic member includes a number of fixed blocks 37 fixedly mounted on the bearing shell 2, a second slide groove 38 opened on the fixed block 37 and a slider 39 slidably mounted on the second slide groove 38. The translation frame 33 and the corresponding slider 39 are fixedly connected. The side of the slider 39 away from the translation frame 33 and the inner wall of the second slide groove 38 are connected by a number of second compression springs 40. The pusher includes a second support block 43 fixedly mounted on the first positioning column 31 and the second positioning column 32 respectively, and a first support plate arranged on the bearing shell 2 for supporting the first positioning column 31 and the corresponding second support block 43 41. A second rotating frame 44 is provided on the carrying shell 2 for supporting the second positioning column 32 and the corresponding second supporting plate 42 and rotatably installed in the carrying shell 2.

The second rotating frame 44 is fixedly connected with a first supporting sleeve 45 and a second supporting sleeve 46, and the second supporting sleeve 46 is sleeved on the outside of the first supporting sleeve 45. A plurality of arc-shaped holes 47 are respectively opened on the first supporting sleeve 45 and the second supporting sleeve 46. The first supporting plate 41 and the second supporting plate 42 are respectively fixedly connected with movable columns 48 that match the arc-shaped holes 47. The movable columns 48 on the first supporting plate 41 are located in the corresponding arc-shaped holes 47 on the first supporting sleeve 45.The movable column 48 on the second support plate 42 is located in the corresponding arc-shaped hole 47 on the second support sleeve 46, and the inclination direction of the arc-shaped hole 47 on the first support sleeve 45 is opposite to the inclination direction of the arc-shaped hole 47 on the second support sleeve 46.

The turntable 51 is located on the outside of the carrying shell 2, and an inner hexagonal groove 52 is provided on the turntable 51. A second support portion 53 is fixedly connected to the outer wall of the carrying shell 2, and an insertion rod 54 passes through the second support portion 53. The turntable 51 is provided with a plurality of second slots 56 evenly distributed around the circumference. One end of the insertion rod 54 is fixedly connected to a fixed disk 55, and the other end of the insertion rod 54 is located in the corresponding second slot 56. The fixed disk 55 and the second support portion 53 are connected by a tension spring 57. The staff places the tubular turning parts to be processed above the carrying shell 2 located at the loading and unloading station, and supports the tubular turning parts through a number of supporting blocks 30. The staff drives the fixed plate 55 and the insertion rod 54 to move, the tension spring 57 is in a tensioned state, and the insertion rod 54 is disengaged from the corresponding second slot 56, releasing the position restriction of the turntable 51 and the worm 49. The staff drives the turntable 51 and the worm 49 to rotate through the cooperation of the hexagonal wrench and the hexagonal slot 52. The worm 49 can drive the second rotating frame 44, the first support sleeve 45 and the second support sleeve 46 to rotate through the worm gear 50, so that the movable column 48 slides in the arc hole 47, and the arc hole 47 drags the second support plate 42 to move up or When the first support plate 41 moves downward, the second support plate 42 pushes the second positioning post 32 to rotate relative to the translation frame 33, and the torsion spring 35 is deformed. When the second positioning post 32 contacts the baffle 36, the second positioning post 32 is in a vertical horizontal plane. As the second support plate 42 continues to move upward, the top of the second support plate 42 contacts the inclined surface of the second support block 43, and the second support plate 42 pushes the second support block 43 and the second positioning post 32 to move horizontally.

Finally, several second positioning posts 32 clamp the outer wall of the tubular part to be turned. Similarly, when the first support plate 41 moves downward, The second compression spring 40 drives the slider 39 and the translation frame 33 to move horizontally to the initial position, and the first positioning post 31 and the second support block 43 rotate in the opposite direction relative to the translation frame 33, so that the first positioning post 31 is no longer located on the side of the tubular part to be turned, thereby preventing the first positioning post 31 from interfering with the turning mechanism to turn the inner wall of the tubular part to be turned. When the tubular part to be turned is fixed, the staff drives the fixing plate 55 and the insertion rod 54 to move in the opposite direction, the tension spring 57 returns to the initial state, and the end of the insertion rod 54 is inserted into the corresponding second slot 56, and the position of the rotating disk 51 and the worm 49 is limited by the insertion rod 54, so that the worm 49 is prevented from rotating relative to the bearing shell 2 due to non-human factors. When the dynamic bearing assembly and the tubular part to be turned whose inner wall has been turned are rotated to the lowest switching station, the support seat 58 is first driven upward by the second hydraulic telescopic rod 59 to enable the support seat 58 to support the inner wall of the tubular part to be turned. Similarly, the staff drives the end of the insertion rod 54 out of the corresponding second slot 56 again, and the staff drives the turntable 51 and the worm 49 to rotate in the opposite direction. The first positioning column 31 can press and fix the inner wall of the tubular part to be turned, and the second positioning column 32 no longer presses and fixes the outer wall of the tubular part to be turned. The second positioning column 32 is no longer located on one side of the tubular part to be turned, thereby preventing the second positioning column 32 from interfering with the turning mechanism in turning the outer wall of the tubular part to be turned.
