Description

Technical Field

[0001] The present invention relates to the technical field of gear detection, and in particular to a rigidity detection device and method for gear teeth of a speed reducer. Background Art

[0002] With the rapid development of modern industrial technology, reducers are key components in mechanical transmission systems. Their performance stability and reliability have a vital impact on the operating efficiency and service life of the overall equipment. The rigidity of reducer gear teeth is one of the important indicators to measure its performance. It is directly related to the accuracy, vibration and noise level of the transmission system. Therefore, it is particularly important to accurately and efficiently detect the rigidity of reducer gear teeth.

[0003] Traditional gear rigidity detection methods mostly rely on empirical judgment and simple mechanical tests, such as evaluating the rigidity of the gear by applying pressure directed toward the axis on both sides of the gear. This method is not only cumbersome to operate, but also difficult to accurately reflect the stress conditions of the gear under actual working conditions. The detection results often have large errors. In addition, with the widespread application of high-precision reducers in high-end equipment such as robots and CNC machine tools, higher requirements are placed on the rigidity detection of gear teeth, requiring the development of more precise and automated detection equipment and methods.

[0004] In recent years, with the continuous progress of sensor technology, control technology and computer technology, new technical means have been provided for gear rigidity detection. Domestic and foreign scholars and enterprises have begun to research and develop gear rigidity detection equipment based on advanced measurement technology, aiming to achieve continuous and efficient rigidity detection of the concave surface of gear teeth, and output accurate detection data to help staff intuitively and quickly judge the rigidity condition of the gear.

[0005] However, there are still some shortcomings in the gear rigidity detection equipment in the prior art. For example, some equipment has complex structural design and is difficult to operate and maintain; some equipment has low detection accuracy and cannot meet the detection requirements of high-precision reducers; some equipment has low detection efficiency and cannot meet the detection requirements of large-scale production. Therefore, the development of a reducer gear tooth rigidity detection equipment with simple structure, convenient operation, high detection accuracy and high efficiency has become an urgent problem to be solved. Summary of the invention

[0006] The purpose of the present invention is to provide a rigidity detection device and method for gear teeth of a reducer to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a rigidity detection device and method for reducer gear teeth, comprising a left detection mechanism and a right detection mechanism, the left detection mechanism and the right detection mechanism are asymmetrically arranged structures, the left detection mechanism comprises a machine room, a base block is fixedly installed on the top of the machine room, a middle rail is arranged between every two base blocks, a first gear rack is slidably connected to the middle rail, a fifth power supply assembly is arranged at the end of the middle rail, a plurality of first fixing bars are arranged on the top of the first gear rack, and a plurality of first bolt holes are arranged on each first fixing bar.

[0008] According to the above technical solution, an upper rail is fixedly installed on the side walls of the first bracket and the second bracket, the second gear rack is slidably connected to the upper rail, and a sixth power supply assembly is arranged on the cabin.

[0009] According to the above technical solution, a supporting space is arranged on the top of the second gear rack, and a plurality of vertically placed lifting rails are evenly arranged on the side walls of the supporting space, a central axis disk is slidably connected to the lifting rail, and an energy supply component for driving the central axis disk to run on the lifting rail is arranged inside the second gear rack, a rotating cavity is arranged inside the central axis disk, a main motor is fixedly installed inside the rotating cavity, a loading plate is fixedly installed on the output end of the main motor, a plurality of second fixing bars are fixedly installed on the top of the loading plate, and a plurality of second bolt holes are arranged on each second fixing bar.

[0010] According to the above technical solution, an annular slide rail is fixedly installed in the rotating cavity, and the annular slide rail is slidably connected to the loading plate.

[0011] According to the above technical solution, the first bracket and the second bracket are fixedly installed on the top partition of the cabin, tracks are set on the top of the first bracket and the second bracket, a crossbeam is slidably connected on the two tracks, and a first power supply assembly is set at one end of the crossbeam.

[0012] According to the above technical solution, side rails are provided on the side walls of the beam, a connecting component is slidably connected to the side rails, a second power supply component is fixedly installed on the lower end of the side wall of the connecting component, a reinforcement block is provided on the side of the connecting component, a groove track is provided on the reinforcement block, two vertical sliding supports are slidably connected on the groove track, a detection metal plate can be removably installed on each sliding support, and a third power supply component is provided on the top of the reinforcement block.

[0013] According to the above technical solution, one of the detection metal plates is a hollow plate, in which a tooth gap detection component is arranged, and the other detection metal plate is a solid metal plate.

[0014] According to the above technical solution, the tooth gap detection component includes a fixed rod fixedly installed inside the detection metal plate, a lifting rod fixedly installed in the middle area of ​​the fixed rod, a storage beam with a sliding rail at the bottom fixedly installed at the bottom of the lifting rod, and a plurality of detection brackets are slidably connected to the sliding rail of the storage beam. A tooth gap detection block is detachably installed at the bottom of each detection bracket, and a fourth power supply component is fixedly installed at the end of the storage beam.

[0015] According to the above technical solution, the first detection process is carried out using the tooth gap detection block:

[0016] The detection system drives the detection bracket to move left and right along the direction of the storage beam, driving the tooth gap detection block to move left and right until the tooth gap detection block determined by the detection system to match moves to the positioning area in the middle of the storage beam. After the movement of the detection bracket is completed, the detection system drives the detection bracket to descend and drives the tooth gap detection block to descend, so that the tooth gap detection block determined by the detection system to match protrudes from the remaining tooth gap detection blocks, so that the tooth gap detection block is easy to be inserted into the tooth gap of the gear to be detected. Then the detection system drives the lifting rod to descend to drive the storage beam to descend, and then drives the tooth gap detection block to be inserted into the tooth gap of the gear to be detected. As the lifting rod descends, the tooth gap detection block is driven to descend. The detection system detects the power data used by the lifting rod to descend in real time, and determines whether the gear tooth gap is qualified by judging the power data used by the lifting rod to descend.

[0017] According to the above technical solution, the detection process of the gear under actual use is simulated:

[0018] The gears on the left detection mechanism and the right detection mechanism are at the same horizontal height. The detection system drives the second gear rack on the left detection mechanism to move to the upper rail of the metal rack area, and then drives the second gear rack on the right detection mechanism to move to the upper rail of the metal rack area. At this time, the gears on the left detection mechanism and the right detection mechanism are not in contact. The detection system first drives the main motor on the second gear rack on the left detection mechanism to operate. The operation of the main motor drives the loading plate to rotate. The rotation of the loading plate drives the second fixed bar to rotate. The rotation of the second fixed bar drives the gear on the second fixed bar to rotate. The detection system drives the gear on the right detection mechanism to rotate in the same process, so that the gear tooth gaps on the left detection mechanism and the right detection mechanism match. The detection system drives the gear tooth gaps on the left detection mechanism and the right detection mechanism to engage. Then the gears on the left detection mechanism and the right detection mechanism rotate in opposite directions. The purpose of detecting the rigidity of the gear is achieved by the reverse rotation of the two engaged gears.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention, by providing a tooth gap detection component, selects a suitable tooth gap detection block according to the tooth gap specifications of the gear to detect the gear. Some gears have tooth gaps of different specifications. The tooth gap detection component can solve the detection drawbacks of such gears and speed up the detection speed of such gears. As the lifting rod descends, the tooth gap detection block is driven to descend. The detection system detects the power data used by the lifting rod to descend in real time, and determines whether the tooth gap of the gear is qualified by judging the power data used by the lifting rod to descend.

[0020] By setting up a left detection mechanism and a right detection mechanism, the rigidity performance of the gear when there is a deviation is detected. The purpose of the detection is to place the gear in a high-difficulty environment for detection, and to obtain the rigidity data of the gear through the high-difficulty environment detection. The detection system can self-adjust or adjust the rising distance of a single gear, and then adjust the detection difficulty of the gear, so that the gear has multiple standard rigidity detection environments.

[0038] The lifting rod 18 is a prior art structure, and its function is to be able to perform lifting and lowering movements. The detection bracket 20 is assembled from a telescopic rod, and a connection structure with the tooth gap detection block 21 is installed at the bottom of the detection bracket 20, so that the tooth gap detection block 21 can be installed at the bottom of the detection bracket 20;

[0039] The detection system drives the detection bracket 20 to move left and right along the direction of the object placement beam 19, driving the tooth gap detection block 21 to move left and right, until the detection system determines that the matching tooth gap detection block 21 moves to the positioning area in the middle of the object placement beam 19, and the positioning area is the shaded part in the middle of the object placement beam 19 in the attached figure. When the movement of the detection bracket 20 is completed, the detection system drives the detection bracket 20 to descend and drive the tooth gap detection block 21, so that the tooth gap detection block 21 determined by the detection system to match protrudes from the other tooth gap detection blocks 21, so that the tooth gap detection block 21 is easy to be inserted into the tooth gap of the gear to be detected, and then the detection system drives The lifting rod 18 descends and drives the storage beam 19 to descend, and then drives the tooth gap detection block 21 to be stuck in the tooth gap of the gear to be detected.

The detection system drives the detection metal plate 13 located on the upper part of the reinforcement block 11 to descend, press against the lower detection metal plate 13 and push the lower detection metal plate 13. Then the epitaxial block 23 on the tooth gap detection block 21 stuck in the tooth gap applies pressure to the gear. Through this process, the rigidity of the tooth gap around the gear is detected, and the detection system is used to adjust the power data of the upper detection metal plate 13, and then the purpose of multi-standard detection can be achieved according to the detection requirements.

[0041] A base block 24 is fixedly installed on the top of the cabin 3, a middle rail 25 is arranged between every two base blocks 24, a first gear rack 26 is slidably connected to the middle rail 25, a fifth power supply assembly 27 is arranged at the end of the middle rail 25, and the first gear rack 26 is driven to move on the middle rail 25 by the fifth power supply assembly 27, a plurality of first fixing bars 43 are arranged on the top of the first gear rack 26, and a plurality of first bolt holes 28 are arranged on each first fixing bar 43, and a gear is fixed to the first fixing bar 43 through the first bolt holes 28 to prepare for the gear detection;

A sixth power supply assembly 31 is provided on the machine compartment 3, and the second gear rack 30 is driven to move on the upper rail 29 by the sixth power supply assembly 31. The purpose of providing a double-layer gear rack is that after the tooth gap detection assembly 16 detects the second gear rack 30, the second gear rack 30 can be moved to the area between the left detection mechanism 1 and the right detection mechanism 2 to perform gear matching detection;

[0043] A support space 34 is provided on the top of the second gear storage rack 30, and a plurality of vertically placed lifting rails 35 are evenly provided on the side walls of the support space 34. A central axis plate 36 is slidably connected to the lifting rail 35, and an energy supply component driving the central axis plate 36 to run on the lifting rail 35 is provided inside the second gear storage rack 30. A rotating cavity 39 is provided inside the central axis plate 36, and a main motor 40 is fixedly installed inside the rotating cavity 39.

The rigidity detection data of the gear can also be obtained. The detection system analyzes and processes the collected rigidity detection data, and outputs the rigidity detection results of each tooth gap of the gear teeth;

[0046] The gear matching detection process is as follows: the gears on the left detection mechanism 1 and the right detection mechanism 2 are at the same horizontal height, the detection system drives the second gear rack 30 on the left detection mechanism 1 to move to the upper rail 29 of the metal frame 32 area, and then drives the second gear rack 30 on the right detection mechanism 2 to move to the upper rail 29 of the metal frame 32 area. At this time, the gears on the left detection mechanism 1 and the right detection mechanism 2 are not in contact, the detection system first drives the main motor 40 on the second gear rack 30 on the left detection mechanism 1 to operate, the operation of the main motor 40 drives the loading plate 41 to rotate, the rotation of the loading plate 41 drives the second fixed bar 37 to rotate, the rotation of the second fixed bar 37 drives the gear on the second fixed bar 37 to rotate, the detection system drives the gear on the right detection mechanism 2 to rotate in the same process, so that the gear tooth gaps on the left detection mechanism 1 and the right detection mechanism 2 match, the detection system drives the gear tooth gaps on the left detection mechanism 1 and the right detection mechanism 2 to engage, and then the gears on the left detection mechanism 1 and the right detection mechanism 2 rotate in opposite directions, The purpose of detecting the rigidity of the gear is achieved by the counter-rotation of two engaged gears. The advantage of this detection method is that it simulates the environment in which the gear is actually used, so that the rigidity detection quality of the gear is higher. After the detection is completed, the detection system drives the gears on the left detection mechanism 1 and the right detection mechanism 2 to separate, and drives a gear on the left detection mechanism 1 or the right detection mechanism 2 to rise. The rising process is that the detection system drives the middle axis disk 36 to rise on the lifting track 35, driving the gear thereon to rise, so that there is a height difference between the gears on the left detection mechanism 1 and the right detection mechanism 2, but there is an overlapping part between the two gears. The detection system repeats the above gear matching detection process again. The purpose of this detection method is to detect the rigidity performance of the gear when there is a deviation. The detection purpose is to place the gear in a high-difficulty environment for detection, and obtain the rigidity data of the gear by high-difficulty environment detection. The detection system can self-adjust or adjust the rising distance of a single gear, and then adjust the detection difficulty of the gear, so that the gear has multiple standard rigidity detection environments;

[0047] The first gear rack 26 below is used to test gears that do not need to undergo a tooth gap rigidity test. After undergoing the test of the tooth gap detection assembly 16, the gears are moved to the carrier rack 44 disposed on the metal frame 32 through the middle rail 25 and are then moved away manually.

[0048] The purpose of setting up a double-layer structure of the above equipment is to realize the detection of gears with different detection standards, and also to achieve the effect of staggered layer detection, so that when the gear matching detection process is carried out on the upper gear, the lower gear can also be detected by the tooth gap detection component 16;

The working method of the rigidity detection device for the gear teeth of a reducer according to claim 5 is characterized in that: The detection process of simulating the actual use of gears: The gears on the left detection mechanism (1) and the right detection mechanism (2) are at the same level. The detection system drives the second gear rack (30) on the left detection mechanism (1) to move onto the upper rail (29) in the metal frame (32) area, and then drives the second gear rack (30) on the right detection mechanism (2) to move onto the upper rail (29) in the metal frame (32) area. At this time, the gears on the left detection mechanism (1) and the right detection mechanism (2) are not in contact. The detection system first drives the main motor (40) on the second gear rack (30) on the left detection mechanism (1) to operate. The operation of the main motor (40) drives the second gear rack (30) on the left detection mechanism (1) to operate. The loading plate (41) rotates, and the rotation of the loading plate (41) drives the second fixing bar (37) to rotate, and the rotation of the second fixing bar (37) drives the gear on the second fixing bar (37) to rotate. The detection system drives the gear on the right detection mechanism (2) to rotate in the same process, so that the gear teeth on the left detection mechanism (1) and the right detection mechanism (2) match. The detection system drives the gear teeth on the left detection mechanism (1) and the right detection mechanism (2) to engage, and then the gears on the left detection mechanism (1) and the right detection mechanism (2) rotate in opposite directions. The purpose of detecting the rigidity of the gear is achieved by the reverse rotation of the two engaged gears.
