The invention discloses a worm and gear small assembly running-in testing device with a variable load, which comprises a support frame, and a workpiece conveying mechanism, a workpiece loading and unloading mechanism, an adjusting and testing seat, a debugging mechanism and a testing mechanism which are separately arranged on the support frame, and is characterized in that the workpiece conveying mechanism is arranged on one side of the adjusting and testing seat and is used for conveying a workpiece; the adjusting and measuring seat is used for fixing a workpiece; the workpiece feeding and discharging mechanism is arranged above the adjusting and testing base and used for feeding and discharging of workpieces. The debugging mechanism is arranged on the other side of the debugging and testing seat and is used for loosening and tightening an adjusting screw of the workpiece for debugging; the testing mechanism comprises a worm driving mechanism and a worm gear driving mechanism, the worm driving mechanism is used for applying load to the worm end of the workpiece, and the worm gear driving mechanism is used for driving a worm gear of the workpiece to rotate and measuring the friction torque of the worm gear end. The invention further discloses a corresponding running-in test method. The gap between the worm gear and the worm in the gearbox can be adjusted by adjusting the screw, and whether the friction torque of the worm gear end meets the specified requirement or not is tested in real time.
Description
technical field [0001] The invention relates to an assembly testing technology of a servo unit, in particular to a running-in testing device and method for a worm gear and worm small assembly with variable load. Background technique [0002] like Figure 1 to Figure 2 As shown, after the servo housing 1 is assembled with the worm and the worm wheel assembly, it is necessary to perform a running-in and torque test, adjust the gap between the worm wheel 3 and the worm 4 by tightening the adjusting screw 2, and apply a load on the worm end 41. run-in, and at the same time, the friction torque of the worm gear end 31 is required to meet the specified requirements. figure 1 5 is the connection sleeve. [0003] The friction torque test station of the servo unit gearbox in the existing assembly line can only be used for the friction torque test of the static running-in of the workpiece, and cannot meet the new product process requirements of automatic screw adjustment, running-in...
