[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0020] Reference Figure 1-Figure 4As shown, a multi-dimensional integrated measurement workstation for parts includes a worktable 1 and a lifting platform 5. The worktable 1 has a first drive cavity 101 inside. Four evenly distributed second slide grooves 6 are formed through the upper end of the worktable 1. Two symmetrically distributed first support plates 7 and second support plates 8 are fixedly connected inside the worktable 1. A first bidirectional lead screw 9 is rotatably connected between the two first support plates 7, and a second bidirectional lead screw 10 is rotatably connected between the two second support plates 8. The second bidirectional lead screw 10 and the first bidirectional lead screw 9 are staggered vertically. Symmetrically distributed first inner clamping plates 11 and second inner clamping plates 12 are threaded onto the outer surfaces of both the first bidirectional lead screw 9 and the second bidirectional lead screw 10. A first infrared emitter 13 is disposed inside the first inner clamping plate 11, and a first infrared receiver 14 is disposed inside the second inner clamping plate 12 at a position corresponding to the first infrared emitter 13. Both the first inner clamping plates 11 and the second inner clamping plates 12 are slidably connected to the inner sides of the second slide grooves 6. The lifting platform 5 has a second drive cavity 501 inside. The lower end of the lifting platform 5 has a first slide groove 502 through it. The second drive cavity 501 is fixedly connected to two symmetrically distributed third support plates 18 and fourth support plates 19. A third bidirectional lead screw 20 is rotatably connected between the two third support plates 18, and a fourth bidirectional lead screw 21 is rotatably connected between the two fourth support plates 19. The third bidirectional lead screw 20 and the fourth bidirectional lead screw 21 are staggered vertically. The outer surfaces of the third bidirectional lead screw 20 and the fourth bidirectional lead screw 21 are threaded with symmetrically distributed first outer clamping plates 22 and second outer clamping plates 23. A second infrared emitter 24 is provided on the inner side of the first outer clamping plate 22. A second infrared receiver 25 is provided on the inner side of the second outer clamping plate 23 at the corresponding position of the second infrared emitter 24. The first outer clamping plate 22 and the second outer clamping plate 23 are slidably connected to the inside of the first slide groove 502. A laser interferometer 29 is provided at the center of the lower end of the lifting platform 5.
[0021] Furthermore, a first motor 17 for driving the second bidirectional lead screw 10 to rotate is fixedly installed on the outer side of the second support plate 8 on one side. A first worm gear 16 is fixedly connected to the outer surface of the second bidirectional lead screw 10. A first gear 15 is fixedly connected to the outer surface of the first bidirectional lead screw 9. The first gear 15 and the first worm gear 16 mesh with each other.
[0022] Furthermore, a second motor 30 for driving the fourth bidirectional lead screw 21 to rotate is fixedly installed on the outer side of the fourth support plate 19 on one side. A second worm gear 26 is fixedly connected to the outer surface of the fourth bidirectional lead screw 21. A second gear 27 is fixedly connected to the outer surface of the third bidirectional lead screw 20. The second gear 27 and the second worm gear 26 mesh with each other.
[0023] Furthermore, the first motor 17 drives the second bidirectional lead screw 10 to rotate. When the second bidirectional lead screw 10 rotates, the first bidirectional lead screw 9 will rotate synchronously under the transmission action of the first worm gear 16 and the first gear 15. The rotation of the first bidirectional lead screw 9 and the second bidirectional lead screw 10 can drive the first inner clamping plate 11 and the second inner clamping plate 12 to move away from each other, thereby clamping the inner ring of the bearing. When the first inner clamping plate 11 and the second inner clamping plate 12 abut against the inner ring of the bearing, infrared rays are emitted through the first infrared emitter 13, and the first infrared receiver 14 receives the emitted infrared signal, measures the interval between the infrared emission and reception signals, and sends the data to the receiver. The distance between the first inner clamping plate 11 and the second inner clamping plate 12 can be calculated by the external terminal equipment. Then, the thickness of the first inner clamping plate 11 and the second inner clamping plate 12 can be added to this value to obtain the inner diameter of the bearing. Two first inner clamping plates 11 and two inner clamping plates 12 are set respectively, so two sets of data can be obtained during measurement. The accuracy of the measurement can be improved by averaging the two sets of data. The first outer clamping plate 22 and the second outer clamping plate 23 are used to measure the outer diameter of the bearing. Their driving method is the same as that of the first inner clamping plate 11 and the second inner clamping plate 12. However, after the first outer clamping plate 22 and the second outer clamping plate 23 abut against the outer ring of the bearing, the distance between them is the outer diameter of the bearing.
[0024] Furthermore, the laser interferometer 29 can accurately detect the roundness of the bearing through the interference effect. When the laser beam irradiates the inner or outer ring surface of the bearing, if the surface of the bearing is not completely smooth, the reflection of the laser on the surface will undergo subtle changes. By analyzing the phase difference of these reflected lights, the laser interferometer 29 can accurately measure the minute geometric changes on the surface, such as deviations, fluctuations, or imperfect roundness.
[0025] Furthermore, the measuring end of the laser interferometer 29 is located above the second infrared emitter 24 and the second infrared receiver 25 to avoid obstructing the detection path of the second infrared emitter 24 and the second infrared receiver 25. The maximum height of the bearing that the device can detect is lower than the vertical height of the second infrared emitter 24 and the second infrared receiver 25 relative to the worktable 1 when the third support plate 18 and the fourth support plate 19 are in contact with the upper end of the worktable 1.
[0026] Furthermore, two symmetrically distributed guide rods 2 are fixedly connected to the upper end of the workbench 1. A support frame 3 is fixedly connected to the upper end of the guide rods 2. Multiple evenly distributed electric telescopic rods 4 are fixedly connected to the lower end of the support frame 3. The output end of the electric telescopic rods 4 is fixedly connected to the upper end of the lifting platform 5.
[0027] Furthermore, two symmetrically distributed guide blocks 28 are fixedly connected to the outer surface of the lifting platform 5, and the guide blocks 28 are slidably connected to the outer surface of the guide rod 2.
[0028] Furthermore, the lifting platform 5 is higher than the upper end of the workbench 1, and can be raised and lowered by the extension and retraction of the electric telescopic rod 4. The initial position of the lifting platform 5 leaves a certain distance from the workbench 1, and the edge of the bearing is sleeved on the outside of the first inner clamping plate 11 and the second inner clamping plate 12.
[0029] Working principle: In use, the operator places the bearing inner ring onto the outside of the two first inner clamping plates 11 and the two second inner clamping plates 12, and then starts the device. First, the first motor 17 drives the second bidirectional lead screw 10 to rotate. When the second bidirectional lead screw 10 rotates, under the transmission action of the first worm gear 16 and the first gear 15, the first bidirectional lead screw 9 will rotate synchronously. The rotation of the first bidirectional lead screw 9 and the second bidirectional lead screw 10 can drive the first inner clamping plates 11 and the second inner clamping plates 12 to move away from each other, thereby clamping the bearing inner ring. When the first inner clamping plates 11 and the second inner clamping plates 12 abut against the bearing inner ring, infrared rays are emitted through the first infrared emitter 13 and received by the first infrared receiver 14. The infrared signal is measured... The inner diameter of the bearing can be calculated by transmitting and receiving signals at intervals and sending the data to an external terminal device. Then, the electric telescopic rod 4 will drive the first outer clamping plate 22 and the second outer clamping plate 23 to descend and fit against the upper end of the worktable 1. Then, the second motor 30 will drive them to move closer together and abut against the outer ring of the bearing to measure the outer diameter of the bearing. The specific driving process of the first outer clamping plate 22 and the second outer clamping plate 23 is the same as that of the first inner clamping plate 11 and the second inner clamping plate 12. After the inner and outer diameters of the bearing are measured, the laser interferometer 29 will measure the roundness of the bearing through the interference effect. After the roundness measurement is completed, all components of the device will be reset, and the bearing measurement data can be observed through the external terminal device. At this time, the operator can take out the measured bearing.
