Description

Technical Field

[0001] This utility model relates to the field of workpiece height measurement technology, specifically a height measurement device for the housing and bearing end face of a speed reducer. Background Technology

[0002] Measuring the height from the end face of the reducer housing to the end face of the bearing is a crucial step in ensuring the assembly accuracy and operational stability of the transmission system. Its main purpose is to verify the accuracy of the bearing installation position and avoid mechanical failures caused by installation deviations.

[0003] For example, a bearing height measuring device with announcement number CN218329682U includes a lower frame, an upper height measuring fixture on the upper inner side of the height measuring frame, and a height measuring centering fixture on the lower inner side of the height measuring frame. Before measuring the height, a calibration block is first used to calibrate the height measuring mechanism and read the displacement scale value during calibration. After calibration, the bearing is manually placed into the height measuring centering fixture, and the height measuring body automatically lowers the upper height measuring fixture to the test setting position. During height measurement, the upper height measuring fixture is completely detached from the height measuring body, the displacement scale value is automatically read, and the bearing height is automatically calculated. Existing height measuring mechanisms use a "hard" connection between the height measuring body and the upper height measuring fixture, while this height measuring mechanism uses a "soft" connection between the height measuring body and the upper height measuring fixture, thereby reducing the processing accuracy, cost, and assembly and debugging difficulty of structural components, and improving the height measuring accuracy and compatibility.

[0004] However, when measuring the height between the reducer housing and the upper end face of the bearing, an external drive device is needed to rotate the bearing. The vibration generated by the bearing rotation is transmitted to the reducer housing. If the housing is not rigid enough or not securely fixed, the vibration will be further amplified, making the reducer housing prone to horizontal or vertical vibration deviation. This causes the bearing being tested to shift position, making it difficult to maintain a vertical state for testing and reducing the accuracy of subsequent height measurements. Utility Model Content

[0005] The purpose of this invention is to provide a height measuring device for the reducer housing and bearing end face, in order to solve the problem that when measuring height, the vibration generated by the bearing rotation is transmitted to the reducer housing, causing the reducer housing to easily vibrate and deviate in the horizontal or vertical direction, which in turn causes the bearing being tested to deviate in position and reduces the accuracy of subsequent height measurement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a height measuring device for the reducer housing and bearing end face, comprising a base frame, a reducer housing part and a bearing part, wherein a linear guide rail is fixedly installed on the top of the base frame, and a placement plate is fixedly connected to the output end of the linear guide rail;

[0011] By adopting the above technical solution, while the housing pressure head presses against the top surface of the reducer housing, it facilitates the upward support of the drive plate against the bottom surface of the reducer housing, and the inclined block presses against the side of the reducer housing. The support plate will also unfold autonomously while rising, thereby improving the support and fixing effect on the reducer housing, keeping the reducer housing horizontal and the bearing to be measured vertical, and thus improving the measurement accuracy of the distance between the upper surfaces of the reducer housing and the bearing.

[0015] By adopting the above technical solution, the inclined rod drives the support plate to rise. The support plate rotates due to the pressure from the bottom surface of the reducer housing. The support plate drives the rotating block to rotate, and the rotating block acts on the torsion spring, so that the support plate can better fit the bottom surface of the reducer housing.

[0016] Preferably, a spring four is sleeved on the outer side of the inner shaft. The spring four is located on the side of the slider away from the reducer housing. One end of the spring four is fixedly connected to the slider, and the other end of the spring four is fixedly connected to the top block away from the reducer housing.

[0017] By adopting the above technical solution, the other inclined plate will drive the top block to rise, and the top block will drive the horizontal plate and the sticking inclined block to rise, so that the sticking inclined block will press against the side of the reducer housing.

[0018] Preferably, there are at least two housing pressure heads. Measurement section one, measurement section two, and measurement section three are sequentially arranged on one side of the front of the slide. Measurement section one, measurement section two, and measurement section three all include a mounting plate. The mounting plate in measurement section one is fixedly installed with the slide. A clamping cylinder is fixedly installed on the top side of the mounting plate. A vertical plate is fixedly connected to the output end of the clamping cylinder.

[0019] By adopting the above technical solution, the clamping cylinder drives the vertical plate and the bearing outer ring pressure head to descend, and the bearing outer ring pressure head also drives the sensor contact block to descend.

[0020] Preferably, a limiting block is fixedly connected to the lower outer side of the mounting plate, a lifting cylinder is fixedly installed on the other side of the top of the mounting plate, a connecting plate is fixedly connected to the output end of the lifting cylinder, and a displacement sensor is fixedly installed at the bottom of the connecting plate, with the displacement sensor and the sensor contact block at the same vertical position.

[0021] By adopting the above technical solution, the first lifting cylinder is activated, which drives the connecting plate and the displacement sensor to descend until the connecting plate is in contact with the limit block, and the displacement sensor measures the distance to the sensor contact block.

[0022] Preferably, a Y-axis servo drive unit and two X-axis servo drive units are also installed on the outer side of the slide. The output end of the X-axis servo drive unit on one side is fixedly installed with the mounting plate in the second measurement unit, and the output end of the X-axis servo drive unit on the other side is fixedly installed with the mounting plate in the third measurement unit. The output end of the Y-axis servo drive unit is fixedly installed with the X-axis servo drive unit on the other side. Both the X-axis servo drive unit and the Y-axis servo drive unit on one side are fixedly installed with the slide.

[0023] By adopting the above technical solution, the two X-axis servo drive units respectively drive the second and third measurement units to adjust laterally, and the Y-axis servo drive unit drives the third measurement unit to adjust longitudinally.

[0024] Preferably, a lower plate is installed in the middle of the inner slot of the base frame. A second lifting cylinder is fixedly installed on one side of the front of the lower plate. A moving plate is fixedly connected to the output end of the second lifting cylinder. A drive motor is fixedly installed on one side of the top of the moving plate. A belt drive is fixedly installed at the bottom of the moving plate. A sleeve is also rotatably installed on the top of the moving plate. The drive motor drives the sleeve to rotate through the belt drive.

[0025] By adopting the above technical solution, the second lifting cylinder drives the moving plate to rise, and the moving plate drives the drive motor and the sleeve to rise, so that the sleeve passes through the circular groove and is locked to the drive shaft of the reducer housing. Then the drive motor is started, and the drive motor drives the sleeve to rotate at a set speed through the belt drive.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an auxiliary positioning structure and utilizing the cooperation characteristics of the rightmost housing pressure head and contact rod, while the housing pressure head presses against the top surface of the reducer housing, it facilitates the upward support of the drive plate against the bottom surface of the reducer housing, reducing the vertical deviation of the reducer housing, and maintaining the close contact with the inclined block pressing against the side of the reducer housing, reducing the horizontal deviation of the reducer housing. The support plate can rotate independently, conforming to the inclination of the bottom surface of the reducer housing. The support plate also unfolds independently while rising, thereby improving the support and fixing effect on the reducer housing, keeping the reducer housing horizontal and the bearing to be measured vertical, thus improving the measurement accuracy of the distance between the upper surfaces of the reducer housing and the bearing. The specific details are as follows:

[0027] 1. By setting up auxiliary positioning components, the operator starts the main cylinder, which drives the slide table to descend. The slide table then drives the housing pressure head to descend. The rightmost housing pressure head will squeeze one side of the contact rod. The contact rod on one side drives the other side of the contact rod to move through the connecting bar. The contact rod drives the guide rod to compress spring one. The interior of the vertical cylinder and the bend is filled with nitrogen. Nitrogen is an incompressible gas, which causes the guide rod to push the nitrogen inside the vertical cylinder. The nitrogen enters the bend, and the bend drives the slide rod to rise. The slide rod stretches spring two, and the slide rod drives the inclined plate to move. The inclined plate drives the collar and the inclined rod to rise, and the inclined rod drives the support plate to rise. The two inclined rods and the support plate are separated from each other. Spring three is stretched by the two inclined rods. The support plate contacts the bottom surface of the reducer housing, and the support plate is subjected to reduction. The pressure on the bottom surface of the reducer housing causes it to rotate, and the support plate drives the rotating block to rotate. The rotating block acts on the torsion spring, allowing the support plate to better fit the bottom surface of the reducer housing. The inclined plate on the other side drives the top block to rise, and the top block drives the horizontal plate and the pressing inclined block to rise. The top inclined surface of the pressing inclined block is pressed by the side of the reducer housing, which drives the horizontal plate to move. The horizontal plate drives the slider to move. The slider slides on the outside of the inner shaft and compresses the spring until the horizontal plate fits against the bottom surface of the reducer housing. The pressing inclined block presses against the side of the reducer housing. At this time, the housing pressure head is pressed against the top surface of the reducer housing. With the help of the cylinder and support column, it is easy to keep the reducer housing in a horizontal position and the bearing to be measured in a vertical position, which improves the subsequent measurement accuracy.

[0028] 2. The operator places the reducer housing on top of the placement plate, then starts the main cylinder. The main cylinder drives the slide to descend, which in turn drives the three housing pressure heads to descend. The rightmost housing pressure head, in conjunction with the auxiliary positioning component, facilitates stable positioning of the reducer housing. The position of measuring section one is fixed, measuring section two can move laterally, and measuring section three can perform lateral and longitudinal measurements to accommodate measurements of different numbers and spacings of bearings. Two X-axis servo drives drive measuring sections two and three laterally, respectively, while the Y-axis servo drive drives measuring section three longitudinally. The mounting plate is fixedly installed on the slide and will rise and fall together with the slide. During measurement, the operator starts the clamping cylinder, which drives the vertical plate and the bearing outer ring pressure head to descend, pressing the bearing outer ring pressure head downwards. The head will also cause the sensor contact block to descend, while the limit block remains stationary, until the bearing outer ring pressure head presses against the outer ring of the bearing. Then, the second lifting cylinder is activated, which drives the moving plate to rise. The moving plate drives the drive motor and the sleeve to rise, so that the sleeve passes through the circular groove and engages with the drive shaft of the reducer housing. The drive motor is then activated, and it drives the sleeve to rotate at a set speed through the belt drive. After the rotation stabilizes, the first lifting cylinder is activated, which drives the connecting plate and the displacement sensor to descend until the connecting plate is in contact with the limit block. The displacement sensor measures the distance to the sensor contact block. At this time, the reading of the displacement sensor is compared with that of the calibration block to calculate the measured value. The measurement method of the calibration block is the same as that of the reducer housing. Attached Figure Description

[0046] A vertical frame 4 is fixedly connected to one side of the back of the base frame 1. A main cylinder 8 is fixedly installed on the top of the vertical frame 4. A slide 9 is fixedly connected to the output end of the main cylinder 8. A housing pressure head 10 is fixedly connected to the bottom of the slide 9. By starting the main cylinder 8, the main cylinder 8 can drive the slide 9 and the housing pressure head 10 to rise and fall.

[0047] like Figure 9 - Figure 14As shown, an auxiliary positioning component 7 is provided on the top of the placement plate 3. The auxiliary positioning component 7 includes two base plates 71 fixedly installed on the top of the placement plate 3. Two vertical cylinders 75 are fixedly connected to the top of the base plates 71. A guide rod 77 is slidably installed on the top of the vertical cylinders 75. A contact rod 79 is fixedly connected to the top of the guide rod 77. A connecting strip 727 is fixedly connected between the two contact rods 79.

[0048] A cylinder 72 and a support column 73 are fixedly connected to the top of the substrate 71. A vertical groove 74 is formed inside the substrate 71, which passes through the placement plate 3, so that the placement plate 3 will not obstruct the sleeve 19. A spring 76 is fixedly connected to the inner bottom surface of the vertical cylinder 75. The top end of the spring 76 is fixedly connected to the bottom end of the guide rod 77 through a piston. The guide rod 77 pushes nitrogen gas through the piston. Two bent pipes 710 are symmetrically fixedly installed on the lower outer side of the vertical cylinder 75. An inclined plate 713 is slidably installed on the top of the bent pipe 710. The top of one inclined plate 713 is symmetrically rotated. Two inclined rods 714 are installed. A support plate 720 is rotatably mounted on the top of the inclined rods 714. A retaining block 726 is slidably mounted on the top of the inclined plate 713 on the other side. A collar 78 is slidably connected to the outside of the vertical cylinder 75. The collar 78 is fixedly connected to both inclined plates 713. The inside of the vertical cylinder 75 and the inside of the bent pipe 710 are filled with nitrogen. A second spring 711 is fixedly installed at the bottom inside the bent pipe 710. The top of the second spring 711 is fixedly connected to a slide rod 712 through a piston. The piston plays a sealing role and keeps the nitrogen gas stable, pushing the slide rod 712 upward.

[0049] The slide rod 712 is slidably connected to the bend 710. The top end of the slide rod 712 is fixedly connected to the inclined plate 713. A spring 715 is fixedly connected between the two inclined rods 714. Two connecting blocks 716 are fixedly connected to the top end of the inclined rods 714. A horizontal shaft 717 is rotatably connected between the two connecting blocks 716. A rotating block 718 is fixedly connected to the middle of the outer side of the horizontal shaft 717.

[0050] The top of the rotating block 718 is fixedly connected to the support plate 720. Two torsion springs 719 are sleeved on the outer side of the horizontal shaft 717. The two ends of the torsion springs 719 are fixedly connected to the connecting block 716 and the rotating block 718 respectively. The support plate 720 will rotate when it is squeezed by the bottom surface of the reducer housing 5. The support plate 720 drives the rotating block 718 to rotate. The rotating block 718 acts on the torsion springs 719, which makes it easier for the support plate 720 to better fit the bottom surface of the reducer housing 5. Two top blocks 721 are fixedly connected to the top of the inclined plate 713 on the other side. An inner shaft 722 is fixedly connected between the two top blocks 721. A slider 723 is slidably connected to the outer side of the inner shaft 722.

[0051] A spring 724 is sleeved on the outer side of the inner shaft 722. The spring 724 is located on the side of the slider 723 away from the reducer housing 5. One end of the spring 724 is fixedly connected to the slider 723, and the other end of the spring 724 is fixedly connected to the top block 721 away from the reducer housing 5. A horizontal plate 725 is fixedly connected to the top of the slider 723. The top of the horizontal plate 725 is fixedly connected to the inclined block 726. The inclined surface of the top of the inclined block 726 is squeezed by the side of the reducer housing 5, which will drive the horizontal plate 725 to move. The horizontal plate 725 drives the slider 723 to move. The slider 723 slides on the outer side of the inner shaft 722 and compresses the spring 724. The inclined block 726 presses against the side of the reducer housing 5.

[0052] Example 1: As Figure 9 - Figure 14 As shown, the operator starts the main cylinder 8, which drives the slide table 9 to descend. The slide table 9 drives the housing pressure head 10 to descend. The rightmost housing pressure head 10 will squeeze the contact rod 79 on one side. The contact rod 79 on one side drives the contact rod 79 on the other side to move through the connecting bar 727. The contact rod 79 drives the guide rod 77 to compress the spring 76. The interior of the vertical cylinder 75 and the bent pipe 710 is filled with nitrogen. Nitrogen is an incompressible gas, which causes the guide rod 77 to push the nitrogen inside the vertical cylinder 75. The nitrogen enters the bent pipe 710. The bent pipe 710 drives the slide rod 712 to rise. The slide rod 712 stretches the spring 711. The slide rod 712 drives the inclined plate 713 to move. The inclined plate 713 drives the collar 78 and the inclined rod 714 to rise. The inclined rod 714 drives the support plate 720 to rise.

[0053] Furthermore, the two inclined rods 714 and the support plate 720 are spread apart from each other, and the spring 715 is stretched by the two inclined rods 714. The support plate 720 contacts the bottom surface of the reducer housing 5. The support plate 720 rotates due to the pressure from the bottom surface of the reducer housing 5. The support plate 720 drives the rotating block 718 to rotate. The rotating block 718 acts on the torsion spring 719, so that the support plate 720 can better fit the bottom surface of the reducer housing 5. The other inclined plate 713 drives the top block 721 to rise. The top block 721 drives the horizontal plate 725 and the sticking inclined block 726 to rise. The top inclined surface of the sticking inclined block 726 is pressed by the side of the reducer housing 5, which drives the horizontal plate 725 to move. The horizontal plate 725 drives the slider 723 to move.

[0054] The slider 723 slides on the outside of the inner shaft 722 and compresses the spring 724 until the horizontal plate 725 is in contact with the bottom surface of the reducer housing 5, and the inclined block 726 presses against the side of the reducer housing 5. At this time, the housing pressure head 10 is pressed against the top surface of the reducer housing 5. Together with the cylinder 72 and the support column 73, it is easy to keep the reducer housing 5 in a horizontal position and the bearing 6 to be measured in a vertical position, thereby improving the accuracy of subsequent measurements.

[0055] like Figure 2 - Figure 8 As shown, there are at least two housing pressure heads 10. The housing pressure heads 10 are used to press the top surface of the reducer housing part 5.

[0058] The outer side of the slide table 9 is also equipped with a Y-axis servo drive unit 111 and two X-axis servo drive units 110. The output end of one X-axis servo drive unit 110 is fixedly installed with the mounting plate 101 in the second measuring unit 12 to realize the lateral adjustment of the second measuring unit 12. The output end of the other X-axis servo drive unit 110 is fixedly installed with the mounting plate 101 in the third measuring unit 13, and the output end of the Y-axis servo drive unit 111 is fixedly installed with the other X-axis servo drive unit 110. Both the X-axis servo drive unit 110 and the Y-axis servo drive unit 111 on one side are fixedly installed with the slide table 9, thereby realizing the lateral and longitudinal adjustment of the third measuring unit 13, which is convenient for adapting to the measurement of bearing units 6 with different numbers and different spacings.

[0059] The lower plate 14 is installed in the middle of the internal slot of the base frame 1. A second lifting cylinder 15 is fixedly installed on one side of the front of the lower plate 14. A moving plate 16 is fixedly connected to the output end of the second lifting cylinder 15. A drive motor 17 is fixedly installed on one side of the top of the moving plate 16. A belt drive unit 18 is fixedly installed at the bottom of the moving plate 16. A sleeve 19 is also rotatably installed on the top of the moving plate 16. The drive motor 17 drives the sleeve 19 to rotate through the belt drive unit 18.

[0060] Example 2: Figure 3 - Figure 8As shown, the operator places the reducer housing 5 on top of the placement plate 3, then starts the main cylinder 8. The main cylinder 8 drives the slide 9 to descend, and the slide 9 drives the three housing pressure heads 10 to descend. The rightmost housing pressure head 10, in conjunction with the auxiliary positioning component 7, facilitates the stable positioning of the reducer housing 5. The position of the measuring part 11 is fixed, the measuring part 2 12 can move laterally, and the measuring part 3 13 can perform lateral and longitudinal movement measurements, which is convenient for adapting to the measurement of bearing parts 6 with different numbers and spacings. The two X-axis servo drive units 110 drive the measuring part 2 12 and the measuring part 3 13 to adjust laterally, respectively, and the Y-axis servo drive unit 111 drives the measuring part 3 13 to adjust longitudinally. The mounting plate 101 is fixedly installed on the slide 9 and will rise and fall together with the slide 9.

[0061] During measurement, the operator activates the clamping cylinder 102, which causes the vertical plate 103 and the bearing outer ring pressure head 104 to descend. The bearing outer ring pressure head 104 also causes the sensor contact block 106 to descend, while the position of the limit block 105 remains unchanged until the bearing outer ring pressure head 104 presses against the outer ring of the bearing part 6. Then, the lifting cylinder 15 is activated, which causes the moving plate 16 to rise. The moving plate 16 causes the drive motor 17 and the sleeve 19 to rise, so that the sleeve 19 passes through the circular groove 74 and is locked in place with the drive shaft of the reducer housing part 5. Then, the drive motor 17 is activated, which drives the sleeve 19 to rotate at a set speed through the belt drive part 18.

[0062] After the rotation stabilizes, the lifting cylinder 107 is then activated. The lifting cylinder 107 drives the connecting plate 108 and the displacement sensor 109 to descend until the connecting plate 108 is in contact with the limit block 105. The displacement sensor 109 measures the distance to the sensor contact block 106. At this time, the reading of the displacement sensor 109 is compared with that of the calibration block to calculate the measured value. The measurement method of the calibration block is the same as that of the reducer housing 5.

[0063] Working principle: When using this device, firstly, as... Figure 1 - Figure 14As shown, the operator places the reducer housing 5 on top of the placement plate 3, then starts the main cylinder 8. The main cylinder 8 drives the slide 9 to descend, and the slide 9 drives the three housing pressure heads 10 to descend. The rightmost housing pressure head 10 will press against the contact rod 79 on one side, and the support plate 720 will contact the bottom surface of the reducer housing 5. The inclined block 726 will press against the side of the reducer housing 5. At this time, the housing pressure head 10 is pressed against the top surface of the reducer housing 5. With the help of the cylinder 72 and the support column 73, it is easy to keep the reducer housing 5 in a horizontal position and the bearing 6 to be tested in a vertical position. The two X-axis servo drive units 110 drive the measuring unit 2 12 and measuring unit 3 13 to adjust laterally, respectively. The Y-axis servo drive unit 111 drives the measuring unit 3 13 to adjust longitudinally. The mounting plate 101 is fixedly installed on the slide 9 and will rise and fall together with the slide 9. During measurement, the operator starts the clamping cylinder 102. The clamping cylinder 102 drives the vertical plate 103 and the bearing outer ring pressure head 10. As the bearing outer ring pressure head 104 descends, it also drives the sensor contact block 106 to descend, while the position of the limit block 105 remains unchanged, until the bearing outer ring pressure head 104 presses against the outer ring of the bearing part 6. Then, the second lifting cylinder 15 is activated, which drives the moving plate 16 to rise. The moving plate 16 drives the drive motor 17 and the sleeve 19 to rise, so that the sleeve 19 passes through the circular groove 74 and is locked in place with the drive shaft of the reducer housing part 5. Then, the drive motor 17 is activated, which drives the sleeve 19 to rotate at a set speed through the belt drive part 18. Then, the first lifting cylinder 107 is activated, which drives the connecting plate 108 and the displacement sensor part 109 to descend, until the connecting plate 108 is in contact with the limit block 105. The displacement sensor part 109 measures the distance to the sensor contact block 106. At this time, the reading of the displacement sensor part 109 is compared with that of the calibration block to calculate the measured value. The measurement method of the calibration block is the same as that of the reducer housing part 5.
