DETAILED DESCRIPTION
[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0020] Example: Figure 1-Figure 3 As shown, a machine tool track inspection fixture includes a stable base 1, a support frame 2 and a placement plate 10 are fixedly installed on the upper surface of the stable base 1, a top plate 3 is fixedly installed on the top of the support frame 2, a cylinder telescopic rod group 6 is fixedly installed on the upper surface of the top plate 3, a first threaded rod 7 and a second slide bar 18 are rotatably installed between the support frames 2, two first slide bars 16 are fixedly installed between the support frames 2, an infrared rangefinder 12 is provided on the first threaded rod 7 and the first slide bar 16, and a limit block 9 is installed on the upper surface of the placement plate 10.
[0021] The cylinder telescopic rod group 6 includes two cylinder telescopic rods, which penetrate downwardly through the top plate 3 and are fixedly connected to the top plate 3. A pressure plate 8 is fixedly installed at the end of each cylinder telescopic rod, and a pressure sensor is fixedly installed on the lower surface of the pressure plate 8. The cylinder telescopic rod group 6 telescopes synchronously to apply pressure to both sides of the upper surface of the machine tool track above the placement plate 10. Since the cylinder telescopic rod 6 telescopes synchronously, if there is a difference in the data of the two pressure sensors, it means that there is a height difference on both sides of the machine tool track.
[0022] The first slide block 4 is sleeved on the first threaded rod 7, the second slide block 5 is sleeved on the first slide block 16, and the first slide block 4 is sleeved on the second slide block 18. The first slide block 4 is threadedly connected to the first threaded rod 7, the second slide block 5 is slidably connected to the first slide block 16, the first slide block 4 is slidably connected to the second slide block 18, and a linkage rod is fixedly connected between the first slide block 4 and the second slide block 5. When the first threaded rod 7 rotates, it drives the two first slide blocks 4 on the first threaded rod 7 to move toward each other, and at this time the second slide block 5 is also driven to move synchronously.
[0023] A connecting rod 11 is fixedly installed between the first sliders 4, and a vertical infrared rangefinder 12 is fixedly installed in the middle of the connecting rod 11. A horizontal infrared rangefinder 12 is fixedly installed on the inner surface of the second slider 5. A second servo motor 15 is fixedly installed on the outer surface of the support frame 2. The rotating shaft of the second servo motor 15 is coaxially fixedly connected with the first threaded rod 7. The servo motor drives the first threaded rod 7 to rotate, and drives the first slider 4 and the second slider 5 to move horizontally synchronously. The vertical infrared rangefinder 12 continuously measures the distance to the upper surface of the machine tool track as it moves. Multi-point measurement can determine whether there is a height difference on the upper surface of the machine tool track. Similarly, the horizontal infrared rangefinder 12 can determine whether there is a height difference at various parts of the side of the machine tool track.
[0024] A second threaded rod 17 is rotatably installed inside the placement plate 10, and a second slide rod 18 is fixedly installed inside the stable base 1. Two third sliders 13 are respectively mounted on the second threaded rod 17 and the second slide rod 18. The third slider 13 is threadedly connected to the second threaded rod 17, and the third slider 13 is slidably connected to the second slide rod 18. The upper surface of the third slider 13 is fixedly connected to the limit block 9. A sliding groove is provided on the placement plate 10, and the limit block 9 is slidably connected to the upper surface of the placement plate 10 through the sliding groove. The limit blocks 9 clamp the machine tool rail from both sides of the machine tool rail. Since the two limit blocks 9 move toward the center at the same time, the machine tool rail is located at the center of the placement plate 10 when finally clamped.
[0025] A first servo motor 14 is fixedly installed on the outer surface of the placement plate 10. The rotating shaft of the first servo motor 14 is coaxially fixedly connected to the second threaded rod 17. A fixed rod is fixedly connected between the two third sliders 13 on the same side. When the first servo motor 14 drives the second threaded rod 17 to rotate, it can drive the third slider 13 on the second slide rod 18 to move simultaneously.
[0026] An operation panel and several display screens are fixedly installed on the outer surface of the stable base 1. The pressure sensor and the infrared rangefinder 12 are electrically connected to the operation panel and the display screen. The first servo motor 14 and the second servo motor 15 are electrically connected to the operation panel and the display screen. The several display screens can respectively display the measurement values of the pressure sensor and the measurement values of the infrared rangefinder 12, which is convenient for the operator to record.
[0027] Working principle: When using this kind of machine tool track inspection fixture, place the machine tool track to be inspected on the upper surface of the placement plate 10, start the first servo motor 14 to drive the second threaded rod 17 to rotate, drive the third slide block 13 on the second slide bar 18 to move at the same time, and the limit blocks 9 clamp the machine tool track from both sides. Since the two limit blocks 9 move toward the center at the same time, the machine tool track is located at the center of the placement plate 10 when it is finally clamped;
[0028] After clamping is completed, the second servo motor 15 is started to adjust the position of the first slider 4 to one end of the first threaded rod 7, and then the infrared rangefinder 12 is started. At the same time, the second servo motor 15 drives the infrared rangefinder 12 to move from one end of the machine tool track to the other end. During this period, the vertical infrared rangefinder 12 continuously measures the distance to the upper surface of the machine tool track as it moves. Multi-point measurement can determine whether there is a height difference on the upper surface of the machine tool track. Similarly, the horizontal infrared rangefinder 12 can determine whether there is a height difference at various parts of the side of the machine tool track. Several display screens can respectively display the measurement values of the pressure sensor and the measurement values of the infrared rangefinder 12. The operator records the values to complete the detection of the machine tool track.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
