Description

Technical Field

[0001] The present invention relates to the technical field of reducer testing, and specifically provides a dynamic testing device for manufacturing lightweight planetary reducers. Background Art

[0002] During the manufacturing process of planetary gear reducers, testing is required. Under simulated actual working conditions, testing can examine whether the components of the reducer are firm and stable, and whether there are potential fault hazards, ensuring that it can maintain stable performance after long-term operation. Among them, in backlash-adjustable reducers, there is a clearance adjuster that can adjust the clearance and is widely used for clearance compensation work. When conducting backlash testing, a pressure gauge is usually used to detect the pressure display situation after the output shaft of the reducer rotates forward and backward to reflect the backlash accuracy. Currently, the dynamic testing devices for manufacturing lightweight planetary reducers usually directly conduct durability tests on the reducers. For backlash-adjustable reducers, it is not convenient to automatically adjust the tightening degree of the backlash adjuster. The force control in the method of manually adjusting the adjuster and then conducting the test is not accurate enough, which easily increases the wear and resistance of the reducer. If no adjustment is made, the initial backlash of the reducer is too high, the reference value of the detection data is small, it is not convenient to test the adjustment effect of the adjuster, affecting the accuracy of the detection results, and it is also not convenient for the staff to automatically adjust the initial pressure of the pressure gauge during backlash detection, and the manual operation accuracy is low.

[0037] Among them, the gap detection component 3 includes: a detection ring 301, a gap elastic piece 302, a centering electromagnet 303, and a displacement pressure sensor 304. The detection ring 301 is sleeved on the reduction coupling 203. There are two bolts on the detection ring 301, and the two bolts on the detection ring 301 are squeezed and fitted on the reduction coupling 203. A gap elastic piece 302 is fixedly installed on the detection ring 301, and the gap elastic piece 302 is an elastic structure. A centering electromagnet 303 is fixedly installed on the side of the detection ring 301. A displacement pressure sensor 304 is fixedly installed on the detection ring 301, and the displacement pressure sensor 304 is located below the gap elastic piece 302. The rotary power connection component 4 includes a rotary fixing ring 401, a displacement groove 402, and a positioning magnet 403. The rotary fixing ring 401 is fixedly installed on the reduction connection base 103. Two displacement grooves 402 are opened inside the rotary fixing ring 401, and there is a protrusion between the two displacement grooves 402. The gap elastic piece 302 is located at the protrusion between the two displacement grooves 402. A positioning magnet 403 is fixedly installed inside the rotary fixing ring 401. The centering electromagnet 303 is used to magnetically attract the positioning magnet 403. The gap compensation component 5 includes: a compensation rope 501, a fitting electromagnet 502, a lead screw motor 503, and a driving column 504. The end of the compensation rope 501 is fixedly installed on the mounting plate 101. A fitting electromagnet 502 is fixedly installed on the compensation rope 501.

The lead screw motor 503, the power connection piece 205, and the fixing plate 206 are connected in series to the power supply;The use of the clearance compensation component 5 can eliminate the clearance of the input shaft of the reducer 104 before the backlash detection work of the output shaft of the reducer 104 is carried out. This can avoid the problem that the clearance at the input end of the reducer 104 is large after the production or early testing of the reducer 104, which affects the accuracy of the subsequent backlash detection at the output end, and can ensure the data reliability during the subsequent backlash detection work. At the same time, the present structure uses the rotary electrical connection component 4 in conjunction with the clearance detection component 3 to automatically perform detection and compensation when the clearance at the input end is too large, without the need for manual operation, which can improve the machine rice tightening efficiency. At the same time, it can automatically perform, in conjunction with the axial detection component 2, to achieve automatic control to stop tightening the machine rice after the machine rice is tightened and the clearance of the input shaft of the reducer 104 meets the standard, to avoid over-tightening, increased wear of the reducer 104 and resistance during deceleration, without the need for manual adjustment, and optimization. The current testing device is mainly used for testing the reducer 104 of inorganic rice. Once the input end ore is too large, it will directly cause the problem of further increase in clearance after deceleration at the output end, which will directly affect the detection accuracy. Once the reduction When there is a clearance in the reducer 104, the input shaft of the reducer 104 will idle back and forth, and the gap spring piece 302 will contact the displacement slot 402 when being driven to swing, squeezing the gap spring piece 302, and the displacement pressure sensor 304 detects the value change in real time, so that the electromagnet 502 that is energized at this time can be tightly magnetically attracted to the reducer 104 for positioning in advance, and the driving column 504 is inserted into the machine bolt of the reducer 104. At this time, the machine motor 503 slowly drives the machine bolt to tighten, and as the reducer 104 is input, the machine bolt is tightened. The end gap meets the standard, and the elastic support of the V-shaped spring sheet 204 is used to avoid direct jamming. At this time, the power supply sheet 205 slides back and forth on the fixed plate 206 to connect the power, and the motor 503 is controlled to intermittently tighten. Once the displacement pressure sensor 304 detects that the value no longer changes or the change is small, it means that the gap of the reduction coupling 203 disappears. At this time, the reduction coupling 203 is in a standard state. At this time, the power supply sheet 205 and the fixed plate 206 can be controlled to be in a separated state to avoid continuous driving rotation and tightening. ;

[0038] Among them, the magnetic force swinging member 6 further includes a centering electromagnet 603, a positioning cylinder 604, a locking electromagnet 6041, and a swinging extrusion arm 605. The centering electromagnet 603 is fixedly installed inside the swinging arm 601; the positioning cylinder 604 is slidably inserted on the swinging arm 601; the centering electromagnet 603 is used to magnetically attract the positioning cylinder 604; the locking electromagnet 6041 is fixedly installed at the bottom of the positioning cylinder 604; the swinging extrusion arm 605 is fixedly installed at the bottom of the swinging arm 601 through bolts; the centering electromagnet 603, the locking electromagnet 6041, the fitting electromagnet 502, and the pulling-back electromagnet 207 are connected in series to a power source. Using the magnetic force swinging member 6 can facilitate the staff to calibrate the basic pressure, avoid the problems of inaccurate manual operation and difficult precision control. At the same time, this structure does not affect the normal detection work and can be used more flexibly in a magnetic control manner. By magnetically attracting the positioning cylinder 604 with the centering electromagnet 603, the positioning cylinder 604 extends at this time, and the locking electromagnet 6041 is used to magnetically attract the detection slider 701. During the pre-period gap compensation, the pressure sensor 602 is supported, and at this time, it is the basic pressure of the pressure sensor 602.

[0039] Embodiment 2, based on Embodiment 1, the full-circle detection member 7 includes: a detection slider 701 and a microswitch 702. The detection slider 701 is slidably inserted into the mounting plate 101. The side surface of the detection slider 701 is an inclined surface structure. A microswitch 702 is fixedly installed at the bottom of the detection slider 701. The detection slider 701 is located between the swing arm 601 and the swing extrusion arm 605. The side surface of the swing arm 601 is an inclined surface structure. The full-circle detection member 7 further includes: a return spring 703. A return spring 703 is fixedly installed at the bottom of the detection slider 701, and the return spring 703 is located inside the mounting plate 101. The microswitch 702 is electrically connected to the pressure sensor 602. Rotating the output shaft for one week can ensure measuring the backlash from multiple angles and positions, so as to more comprehensively understand the transmission performance and accuracy of the gear. This measurement method helps to discover potential transmission problems, such as gear wear, excessive bearing clearance, etc., and take corresponding maintenance or replacement measures in a timely manner. Using the full-circle detection member 7 can cooperate with the magnetic swing member 6 to ensure that when performing backlash detection, the swing arm 601, that is, the output shaft of the speed reducer 104, automatically powers on for pressure testing after rotating one week, preventing manual forgetting. It can ensure the backlash detection accuracy. In the way of one-way limit, reverse rotation can be limited, and the backlash can be detected in time, reducing the probability of misoperation and ensuring the detection quality. When actually detecting the backlash, a prompt can be directly given. When the swing arm 601 rotates, it drives the swing extrusion arm 605 to squeeze the detection slider 701. The detection slider 701 retracts inward to squeeze the microswitch 702. At this time, the microswitch 702 can turn off the power supply of the pressure sensor 602. As the swing arm 601 continues to rotate, after the swing arm 601 rotates one week, it will squeeze the detection slider 701, and the detection slider 701 retracts inward again, and then can squeeze the microswitch 702 again, and the pressure sensor 602 is powered on. In this way, it is ensured that the pressure sensor 602 can be powered on only within a small range after the swing arm 601 rotates one week. When the swing arm 601 rotates only half a circle and other positions, the backlash cannot be detected. At the same time, this structure uses the detection slider 701 to realize a one-way limit structure. When the detection slider 701 is located between the swing arm 601 and the swing extrusion arm 605, the swing arm 601 can swing within a small range to perform the detection work.

[0040] The working principle of this embodiment is as follows: first, after the reduction coupling 203 is connected to the inlet and outlet shaft ends of the reducer 104 to be detected, the reduction coupling 203 is driven by the driving motor 102 to drive the reducer 104 to rotate together. At this time, as the output shaft of the reducer 104 drives the swing arm 601 to drive the axial attraction magnet 6011 to rotate, the traction magnets 1011 arranged at intervals can be used to magnetically attract the two axial attraction magnets 6011 respectively, and the two axial attraction magnets 6011 are magnetically attracted to both sides respectively. At this time, if there is an axial gap deviation in the main shaft of the reducer 104, it will slide under the action of magnetic attraction, driving the shaft shift sleeve 201 to move on the output shaft of the driving motor 102. At this time, the electronic ruler 202 can detect the position in real time. The data can be displayed on the display external to the electronic ruler 202. When the reduction coupling 203 is connected to the inlet and outlet shaft end connecting sleeve of the reducer 104 to be detected, the centering electromagnet 303 is first turned on to magnetically attract the positioning magnet 403. At this time, the gap spring piece 302 is located at the protrusion between the two displacement grooves 402. Then the reduction coupling 203 is connected to the reducer 104 to be detected and tightened. The positive position electromagnet 603 and the locking electromagnet 6041 are turned on. At this time, the locking electromagnet 6041 can be magnetically positioned on the detection slider 701. At this time, when the driving motor 102 drives the reduction coupling 203 to rotate, the locking electromagnet 6041 is positioned at one end. At this time, the driving motor 102 drives the reduction coupling 203 to move back and forth in a small range. Rotation, once there is a clearance in the reducer 104, the input shaft of the reducer 104 will idle back and forth, and the gap spring piece 302 will contact the displacement slot 402 when being driven to swing, squeezing the gap spring piece 302, and detecting the value change in real time through the displacement pressure sensor 304, so that the fitting electromagnet 502 that is energized at this time can be tightly magnetically attracted to the reducer 104 for positioning in advance, and the driving column 504 is inserted into the machine bolt of the reducer 104. At this time, the machine motor 503 slowly drives the machine bolt to tighten, and as the clearance at the output end of the reducer 104 meets the standard, the elastic support of the V-shaped spring piece 204 is used to avoid direct jamming. At this time, the power supply sheet 205 slides back and forth on the fixed plate 206 to connect the power, and controls the machine motor 503 to tighten intermittently. Once the displacement pressure sensor 304 detects that the value no longer changes or the change is very small, it means that the clearance of the reduction coupling 203 disappears. At this time, the reduction coupling 203 is in a standard state. At this time, the power strip 205 and the fixing plate 206 can be controlled to be in a separated state to avoid continuous driving rotation. Then the positive electromagnet 603, the locking electromagnet 6041 and the fitting electromagnet 502 can be controlled to be powered off, and the machine motor 503 can be removed. At this time, the pull-back electromagnet 207 will also be powered off, and the pull-back electromagnet 207 will no longer magnetically attract the positioning shaft 208. Under the pressure of the spring at the tail of the positioning shaft 208, the positioning shaft 208 will be inserted into the reduction coupling 203 for positioning. At this time, the reduction coupling 203 can normally perform subsequent backlash detection work;

[0041] Magnetically attract the positioning cylinder 604 of the positive electromagnet 603. At this time, the positioning cylinder 604 extends and cooperates with the locking electromagnet 6041 to magnetically attract the detection slider 701. When performing pre-period clearance compensation, support the pressure sensor 602. At this time, it is the basic pressure of the pressure sensor 602. Drive the swing arm 601 on the reducer 104 to rotate through the drive motor 102. When the swing arm 601 rotates, it drives the swing extrusion arm 605 to extrude the detection slider 701. The detection slider 701 retracts inward to squeeze the microswitch 702. At this time, the microswitch 702 can turn off the power supply of the pressure sensor 602. As the swing arm 601 continues to rotate, after the swing arm 601 rotates one full circle, it will squeeze the detection slider 701. The detection slider 701 retracts inward again, and can squeeze the microswitch 702 again, and the pressure sensor 602 is powered on. At this time, control the reverse rotation of the swing arm 601 for the part that exceeds after rotating one full circle. For example, if the swing arm 601 rotates 365 degrees, then reverse rotate 5 degrees at this time to understand the current backlash data. Once the data deviates greatly from the initial data, it indicates that the backlash quality is not good.
