[0044] Embodiment 2

[0045] Different from the first embodiment, in order to clean the spherical surface machining wire scraps in the differential housing, as shown in FIG. Figure 7-Figure 8As shown, a partition 161 is fixedly connected in the cleaning chamber 16, and the partition 161 is fixedly connected to a slide rail 162 on the side close to the clamping chamber 1, and a second slide plate 163 is slidably connected to the inner side of the slide rail 162, and the second slide plate 163 is fixedly connected to a snap-fit ​​member 164 on the side away from the partition 161.

[0046] like Figure 5 As shown, the cleaning assembly 3 includes a rotating rod 31, a sliding rod 32 and a placement plate 33. The sliding rod 32 is slidably connected to the inner side of the rotating rod 31, and the placement plate 33 is fixedly connected to the end of the rotating rod 31 away from the cleaning chamber 16. The outer wall of one end of the sliding rod 32 is fixedly connected to a raised strip 321. The outer wall of the sliding rod 32 at the end away from the raised strip 321 is provided with a thread groove 322. The sliding rod 32 is fixedly connected to a broken wire rod 323 at the end close to the thread groove 322. The outer wall of the broken wire rod 323 is fixedly connected to There is a magnet 3231, and a square hole 331 is opened on the outer wall of the placement plate 33. A fixed connecting rod 333 is fixedly connected in the square hole 331. Both ends of the fixed connecting rod 333 are rotatably connected with push-pull rods 3331. The push-pull rod 3331 is rotatably connected with a fixed roller 3332 at the end away from the fixed connecting rod 333, wherein: the placement plate 33 is fixedly connected with a second fixed column 332 on the side away from the rotating rod 31, and the sliding rod 32 passes through the fixed connecting rod 333, the placement plate 33 and the second fixed column 332.

[0047] like Figure 7 As shown, the toggle assembly 4 includes a motor 41, a turntable 42 and a circular gear 45. The circular gear 45 is fixedly connected to the outer wall of the end of the rotating rod 31 away from the placement plate 33. The motor 41 is fixedly connected to the side of the partition 161 away from the clamping chamber 1. The output end of the motor 41 is fixedly connected to the turntable 42. The turntable 42 is provided with an irregular groove 421 on the outer wall on the side away from the motor 41. The turntable 42 is provided with a No. 1 prying link 43 on the outer wall on the side away from the motor 41. The No. 1 prying link 43 is rotatably connected to the upper end of the No. 1 sliding plate 14 at the end away from the turntable 42. The No. 1 prying link 43 is rotatably connected to the limiting member 431 at the end away from the turntable 42. The turntable 42 is rotatably connected to the No. 2 prying link 44 on the side close to the No. 1 prying link 43. The No. 2 prying link 44 is fixedly connected to a rack 441 at the bottom of the end away from the turntable 42, and the rack 441 is meshed with the circular gear 45.

[0048] like Figure 8As shown, the No. 1 prying link 43 is fixedly connected with a No. 2 protruding column 432 at one end away from the limiting member 431 and close to the turntable 42, the diameter of the No. 2 protruding column 432 matches the width of the irregular groove 421, and the limiting member 431 is slidably connected to the top of the No. 2 prying link 44 at the end away from the No. 1 prying link 43, wherein: the middle end of the No. 1 prying link 43 is rotatably connected to one side of the partition 161, and the irregular groove 421 is connected by two arcs of different diameters.

[0049] It can be seen from this that when it is necessary to clean the inner spherical surface of the differential housing, Figure 6-Figure 8 As shown, the rotating disk 42 drives the irregular groove 421 to rotate under the drive of the motor 41. At this time, the second protruding column 432 in the irregular groove 421 will gradually slide from the small circle in the irregular groove 421 to the large circle. At this time, the first prying link 43 will rotate clockwise with the position where its end is connected to the partition 161 as a fulcrum, and the second prying link 44 will be pressed down by the limit member 431. At the same time, the second prying link 44 will pull the second prying link 44 and push the second prying link 44 to move forward under the non-center rotation of the rotating disk 42. When the second prying link 44 is pulled or pushed by the rotating disk 42, the limiting member 431 simultaneously presses the second prying link 44 downward, so that the rack 441 drives the circular gear 45 to rotate a certain angle, and the circular gear 45 drives the rotating rod 31 and the placing disk 33 to rotate. During the rotation of the placing disk 33, the fixed link 333 is driven to pull the push-pull rods 3331 and the fixed roller 3332 at both ends to tighten, and the fixed roller 3332 is used to cooperate with the upper clamping member 251 and the lower clamping member 231 to clamp and fix the differential housing;

[0050] At the same time, after the fixed roller 3332 fixes the position of the differential chassis, after the turntable 42 continues to rotate, the second raised column 432 will gradually slide from the large circle in the irregular groove 421 to the small circle position, so that the first prying link 43 rotates counterclockwise with the position where its middle end is connected to the partition 161 as a fulcrum, and the second prying link 44 is pulled counterclockwise by the limiter 431, and the second sliding plate 163 is pulled up at the same time. At this time, the rack 441 will be separated from the circular gear 45, and the buckle 164 will be stuck around the circular gear 45, limiting the rotation of the circular gear 45 to prevent the circular gear 45 from continuing to rotate due to inertia and thus damaging the operation of the equipment;

[0051] It should be noted that the staff sets the motor 41 during the equipment debugging stage so that the motor 41 counts one slow rotation and then one reverse rotation as one count. The sliding rod 32 in the rotating rod 31 is electrically driven. From the beginning of the motor 41 rotating one circle forward, the sliding rod 32 extends outward from the inner side of the rotating rod 31. After the motor 41 reverses one circle, the sliding rod 32 also retracts to its initial position. In the process of the sliding rod 32 sliding outward, the broken wire rod 323 is driven to extend outward, and the wire scraps are adsorbed on the broken wire rod 323 under the adsorption force of the magnet 3231 for winding, so as to prevent the wire scraps from being entangled in the lathe tool and causing shutdown.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
