Description

Technical Field

[0001] The utility model relates to the technical field of spline shaft detection, and more specifically, to a wear resistance detector for the end of a spline shaft. Background Art

[0002] A spline shaft is a type of mechanical transmission. Similar to a flat key, a half-round key, and a wedge key, it is used to transmit mechanical torque. It has longitudinal keyways on the outer surface of the shaft, and the rotating parts sleeved on the shaft also have corresponding keyways to keep synchronous rotation with the shaft. Some can also slide longitudinally on the shaft while rotating, such as the shift gears in a gearbox.

[0003] During the production and processing of spline shafts, it is necessary to detect the wear resistance of the shaft ends to make the wear resistance of the end faces meet the specified values. When the existing wear resistance detectors detect the wear resistance of the spline shaft end faces, waste chips and dust will be generated, which is harmful to human health after a large amount of inhalation.

[0031] Embodiment 3;

[0032] As Figures 1-6As shown in the figure, it includes an operating table 1. A number of uniformly distributed support blocks 2 are provided at the bottom end of the operating table 1.

The servo motor 12 is started to drive the lead screw 8 to rotate, the lead screw 8 drives the movable vertical frame 9 to move, and the movable vertical frame 9 drives the detection grinding disc to approach the end face of the spline shaft. Subsequently, the drive motor 10 is started to drive the detection grinding disc 11 to rotate for grinding and detecting the end face of the detection grinding disc. By setting the lead screw and the servo motor, it is convenient to adjust the distance between the detection grinding disc 11 and the end face of the spline shaft, saving time and effort without manual pushing by personnel; when waste chips and dust are generated during the grinding process of the detection grinding disc 11, the double-shaft motor 19 is started to drive the main shaft one 20 to rotate, the main shaft one 20 drives the fan blade 21 to rotate, and the fan blade 21 sucks the dust into the dust collection box 13 through the cooperation of the dust suction hood 15 and the connecting pipe 16. The dust entering the dust collection box 13 will be intercepted by the filter screen 18. When the filter holes of the filter screen 18 are blocked, at this time, the main shaft one 20 stops rotating, and the double-shaft motor 19 drives the main shaft two 22 to rotate. The main shaft two 22 drives the mounting plate 23 to rotate, and the mounting plate 23 drives the brush to clean the filter screen 18. By setting the dust suction component, when the detection grinding disc performs grinding detection on the shaft end, the generated waste chips and dust can be effectively and timely absorbed, preventing them from floating into the surrounding environment and being inhaled by personnel, further improving its safety. At the same time, the cooperation of the double-shaft motor and the brush in the dust suction component can clean the filter screen and improve the dust absorption efficiency.
