Description

[0001] The invention relates to the technical field of reducer testing, and in particular to a worm gear reducer torque testing device. Background Art

[0002] Worm gear reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque. Among the mechanisms used to transmit power and motion, it is widely used in various large machines, industrial processing equipment, home appliance clocks and other fields. It has the function of reducing speed and increasing torque, and can be widely used in speed and torque conversion equipment.

[0003] The following problems were found: when performing torque testing, the motor will be restricted and stopped after instantaneous transmission. However, the existing device is not convenient for quick disconnection and locks the data at the same time, which can easily cause the motor to remain stuck and cause the motor to burn out.

[0065] A steel cable 418 is wound around the shaft end of the dial 414, and a pulling wheel is wound around the front end of the steel cable 418.

Through the arrangement of the V-groove 49, the W-groove 410 and the pulling plate 411, the clamping state can be continuously switched, which is convenient for fixing the reducer to facilitate detection.

[0066] The use method and advantages of the present invention: The working process of the worm gear reducer torque test device is as follows:

[0067] like Figures 1 to 16As shown, the staff places the reducer on the mounting seat 413, and the external motor is started at this time. The motor drives the sliding seats 45 on both sides to move in opposite directions through the transmission belt. At this time, due to the setting of the guide groove 42 of the eight-shaped structure, before the moving plates 46 on the two sliding seats 45 meet, one group of sliding seats 45 passes the deepest part of the guide groove 42, so that it is misaligned with the subsequent group of sliding seats 45. At this time, the moving plate 46 on the sliding seat 45 drives the reducer to move to the farthest point, and the motor stops. At this time, the air pressure pump 32 is started to drive the air pressure rod to move downward, and the push plate 33 is pushed to drive the drive rod 35 to expand and move downward to connect with the reducer main shaft. The two are connected by splines. At this time, the servo motor transmits power, and the drive rod 35 drives the transmission rod 37. The transmission rod 37 drives the pressure plate 311 to rotate in the air pressure chamber 312. The pressure plate 311 squeezes the gas in the air pressure chamber 312 to generate pressure. The pressure generated at this time is torque;

[0068] At the same time, when the sliding seat 45 continues to move forward, the moving plate 46 slides in the V-shaped groove through the roller. When it moves from one end of the V-shaped groove to the deepest point, the moving plate 46 moves backward and is misaligned with the sliding seat 45. At this time, since the fixed plate 412 is fixedly connected to the sliding seat 45, when the moving plate 46 drives the control block 48 to move, the pulling plate 411 in the control block 48 moves out of the V-shaped groove and enters the W The pull wheel on the control block 48 will pull the steel cable 418 to move backwards due to the synchronous movement of the control block 48, and the steel cable 418 will drive the dial 414 to rotate. The rotation of the arc groove 415 on the dial 414 will drive the slide bar 416 to move toward the axis of the dial 414, so that the slide bar 416 pushes the extrusion sheet 417 to move outward, and the two extrusion sheets 417 will fit with the surface of the reducer for clamping. Similarly, after the inspection is completed, the moving plate 46 moves in the reverse direction and resets, and the pulling plate 411 enters the V-groove 49 again, releasing the restriction on the dial 414 and the clamping effect, which is convenient for the staff to use;

[0069] Then, due to the rotation of the driving rod 35, the wedge block 36 on the driving rod 35 squeezes the inner rod in the damping telescopic rod 315 to move upward, and the upward movement of the damping telescopic rod 315 squeezes the arc plate 316 to rotate in the inner cavity 314. At this time, the limiting column 317 on the arc plate 316 is inserted into the through hole in the inner cavity 314 and docked with the external toggle wheel 39. Since the limiting column 317 is only set with a single-sided inclined surface, when the toggle rod 310 rotates, the toggle wheel 39 can be driven to rotate through the limiting column 317, and force is stored at the same time.

[0070] Subsequently, due to the sudden increase in pressure in the air pressure chamber 312, the servo motor will only drive the pressure plate 311 to rotate briefly to output the maximum force. At this time, the damping setting inside the damping telescopic rod 315 will cause the inner rod in the damping telescopic rod 315 to move downward slowly until the inner rod is completely moved to the bottom inclined surface of the arc plate 316. The damping telescopic rod 315 loses its restriction on the arc plate 316, and the arc plate 316 is reset by the spring. At the same time, the limiting column 317 of the single-sided inclined surface will be squeezed and contracted when resetting. At this time, the toggle wheel 39 is completely contacted and restricted, and the toggle wheel 39 is reset by the coil spring. The toggle wheel 39 drives the small gear 3139 to rotate through the large gear 31310 , and then the rifle rod 3138 pushes the outer sleeve 3137 to move upward, and the trigger plate 3136 on the outer sleeve 3137 continues to push the left telescopic plate 3132 to slide on the positioning plate 3131 and rotate at the same time, until the angle between the left telescopic plate 3132 and the right telescopic plate 3133 is the largest, and the left telescopic plate 3132 and the right telescopic plate 3133 are instantly retracted inward by stretching the spring rod. At this time, the connection between the left telescopic plate 3132 and the right telescopic plate 3133 moves downward, and the left telescopic plate 3132 and the right telescopic plate 3133 all move upward, and the right telescopic plate 3133 pushes the guide frame 34 and the push plate 33 to rise, disconnecting from the reducer main shaft;

[0071] When the connection between the left telescopic plate 3132 and the right telescopic plate 3133 moves downward, the wiring sleeve arranged therein will pull the cable, and the cable will drive the power storage wheel 31319 to rotate. At the same time, the stopper 31318 on the cable will push the trigger block 31317 to move downward, and the trigger block 31317 will dock with the inclined groove 31315 on the card plate 31314, continuously squeezing the inclined surface of the inclined groove 31315 to push the card plate 31314 to move forward, and the card plate 31314 will abut against the toggle rod 310 to lock the toggle rod 310 so that the pressure reading is maintained until the next reducer detection is performed, and the above operation is performed again. At this time, along with the downward movement of the push plate 33 and the guide frame 34, the left telescopic plate 3132 and the right telescopic plate 3133 will be driven in the reverse direction to reset, and then other parts will also reset together, so that continuous detection can be carried out.

Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
