Description

Technical Field

[0001] The invention relates to the technical field of gear cleaning, in particular to an internally positioned immersion cleaning machine for gears. Background Art

[0002] Gears are widely used in automobile transmissions, differentials and various mechanical equipment. Gears need to be cleaned with a cleaning machine during manufacturing and later use in order to improve the later assembly quality and service life of the gears. At present, there are still some problems when using the cleaning machines on the market, such as: The patent name disclosed in the prior art with the announcement number "CN111871894A" is "A Mechanical Gear Cleaning Device", which discloses that the gear is fixed on the clamping seat, and then the driving motor is started, and the driving motor drives the driving shaft to rotate. On the one hand, the cleaning disc is rotated by the action of the driving gear set, and on the other hand, with the cooperation of the eccentric wheel and the L-shaped frame, the cleaning disc can also move up and down while rotating, thereby increasing the cleaning effect. At the same time, the driven gear set drives the driven shaft to rotate, and then under the action of the transmission gear set, the transmission shaft drives the driving shaft to rotate, thereby ensuring the synchronous rotation of the clamping seat. In the process of the cleaning disc moving up and down, the gear on the clamping seat is always in contact with the cleaning disc under the action of the spring, thereby increasing the cleaning effect. The patent name disclosed in the prior art with the announcement number "CN112207073A" is "A cleaning and maintenance device for the tooth gap of a spur gear", which discloses that the spur gear to be cleaned is placed on a placement block, the contact plate contacts the inner wall of the gear mounting hole, the contact plate moves toward the side close to the symmetry center and drives the limit rod and the first slide plate to slide toward the side close to the symmetry center, the first spring is compressed, the gear to be detected is positioned under the contact of the contact plate, the first adjustment dial is rotated, the first positioning block is moved left or right, the position of the first positioning block is adjusted until the pawl can mesh with the gear teeth of the gear to be detected, the second adjustment dial is rotated, the second positioning block is moved left or right, and the position of the cleaning wheel is adjusted until the cleaning wheel moves left when the two annular electromagnets are attracted to clean the tooth gap of the gear to be detected; The cleaning machine in the prior art can perform internal positioning and clamping on the spur gear to be cleaned by the cooperation between the placement block and the abutment plate when in use. However, the cleaning machine can only perform internal positioning and clamping on one spur gear to be cleaned at a time, and cannot perform internal positioning and clamping on multiple spur gears to be cleaned at the same time. Therefore, only one spur gear to be cleaned can be cleaned at a time, which results in a low cleaning efficiency. Therefore, we propose a gear cleaning machine with internal positioning immersion decontamination to solve the above-mentioned problems. Summary of the invention

[0026] The second threaded rod 14 is threadably connected to the fixing nut 15, so that the second threaded rod 14 is rotated and moved backward in the main bearing rod 12. At this time, the second threaded rod 14 drives the multiple groups of moving blocks 141 with a conical structure to move backward together, and then the outer side surface of the moving block 141 simultaneously pushes the four convex rods 131 in each group outward, and the convex rods 131 penetrate the limit plate 121 to squeeze and store force on the connecting spring 132. At this time, the convex rods 131 drive the corresponding inner positioning plates 13 to move outward, and then the rubber pads on the outer side of the inner positioning plates 13 are tightly in contact with the inner wall of the mounting hole of the gear to be cleaned.
