[0017] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects of the utility model will be described in detail below in combination with the drawings and preferred embodiments.
[0018] Example 1:
[0019] As Figures 1-6The utility model discloses a guide rail working condition straight line precision's detection device, including marble platform 1, be provided with two guide rail stations for installing guide rail on marble platform 1, the bottom reference a of two guide rail stations is parallel to each other, the side reference b of two guide rail stations is parallel to each other, and the bottom reference a of same guide rail station and the side reference b between mutually perpendicular, install a standard guide rail 2 on one of guide rail stations, assemble two sliders 5 on standard guide rail 2, install lever micrometer 4 on each slider 5, set up first hydraulic cylinder 9 on the marble platform 1 of corresponding place of another guide rail station, first hydraulic cylinder 9 is located the side opposite of the side reference b of this guide rail station, set up push plate 10 on the telescopic rod of first hydraulic cylinder 9, and the telescopic rod of first hydraulic cylinder 9 is horizontally towards the side reference b of this guide rail station, and the side reference b of this guide rail station is used for clamping the guide rail 3 to be measured between push plate 10 and, set up the vertical second hydraulic cylinder 7 of going up on the marble platform 1 of this guide rail station side, and the telescopic end of second hydraulic cylinder 7 is provided with pressure plate 8, and pressure plate 8 extends to the just above of the bottom reference a of this guide rail station.
[0020] The guide rail station on marble platform 1 is L-shaped structure, and its bottom reference a and side reference b are perpendicular, and the bottom reference a between two guide rail stations is parallel to each other, and the side reference b is also parallel to each other, so that the bottom between the guide rail 3 to be measured and standard guide rail 2 installed on two guide rail stations and one side is parallel to each other. So if assembling standard guide rail 2 on two guide rail stations, the same part between two standard guide rails 2 is parallel to each other, such as the raceway between two standard guide rails 2 is parallel. And setting up guide rail 3 to be measured on one of guide rail stations, then the parallelism deviation of the same position between guide rail 3 to be measured and standard guide rail 2 can be used to judge the straight line precision of guide rail 3 to be measured, and the working condition straight line precision of guide rail 3 to be measured is detected. Setting up two sliders 5 on standard guide rail 2, setting up a lever micrometer 4 on each slider 5, one micrometer measures the side of guide rail 3 to be measured, such as Figure 3 And the other micrometer measures the raceway of guide rail 3 to be measured, such as Figure 3 Indicated.
[0021] Wherein the push plate 10 on the first hydraulic cylinder 9 and the side reference b of the guide rail station can clamp the guide rail 3 to be tested, the bottom surface of the guide rail 3 to be tested is attached to the bottom surface reference a of the guide rail station, one side of the guide rail 3 to be tested is attached to the side reference b of the guide rail station, and the other side of the guide rail 3 to be tested is pressed by the push plate 10, so that it is clamped between the two, while the second hydraulic cylinder 7 drives the pressing plate 8 to press down, clamping the guide rail 3 to be tested between the bottom surface reference a of the guide rail station. The above process can realize the rapid clamping of the guide rail 3 to be tested, and the clamping state is stable and reliable after replacing the guide rail 3 to be tested each time, so that the assembly error of the guide rail 3 to be tested caused by different assembly processes of different operators is avoided, and the detection accuracy is affected.
[0022] Under normal circumstances, the length of the standard guide rail 2 covers the entire guide rail station, and the length of the guide rail 3 to be tested is often less than that of the standard guide rail 2, so as to ensure that the slider 5 can cover the entire position of the guide rail 3 to be tested during sliding, so as to realize comprehensive detection of the guide rail 3 to be tested.
[0023] The first hydraulic cylinder 9 is evenly arrayed along the length direction of the guide rail station, and the interval between adjacent first hydraulic cylinders 9 is 80mm. The second hydraulic cylinder 7 is evenly arrayed along the length direction of the guide rail station, and the interval between adjacent second hydraulic cylinders 7 is 80mm.
[0024] In actual clamping process, in order to make the assembly of the guide rail 3 to be tested on the guide rail station stable and reliable, reduce the influence of clamping position on the straightness accuracy of the guide rail 3 to be tested, the interval of the first hydraulic cylinder 9 is 80mm, and the interval of the second hydraulic cylinder 7 is also 80mm, so that the design of relatively dense clamping position can make the stress position of the guide rail 3 to be tested uniform and stable, so that the clamping force will not affect the straightness accuracy of the guide rail 3 to be tested, so as to improve the accuracy of the straightness accuracy detection of the guide rail 3 to be tested.
[0025] According to actual test, if the interval between the first hydraulic cylinder 9 and the second hydraulic cylinder 7 is less than 80mm, such as 50mm, and the length of the push plate 10, the clamping position of the guide rail 3 to be tested is too dense, which will cause waste of hydraulic cylinder and energy consumption. If the interval between the first hydraulic cylinder 9 and the second hydraulic cylinder 7 is too large, such as 200mm, it is easy to affect the straightness accuracy of the guide rail 3 to be tested, so that the detection accuracy is reduced. Therefore, 80mm is adopted as the interval between the first hydraulic cylinder 9 and the second hydraulic cylinder 7.
[0026] The first hydraulic cylinder 9 and the second hydraulic cylinder 7 are alternately arranged along the length direction of the guide rail station, and the interval between the first hydraulic cylinder 9 and the two adjacent second hydraulic cylinders 7 is the same, and the interval between the second hydraulic cylinder 7 and the two adjacent first hydraulic cylinders 9 is the same.
[0027] The first hydraulic cylinder 9 and the second hydraulic cylinder 7 are alternately arranged along the length direction of the rail station, so that the side and top of the measured rail 3 are alternately stressed, and the clamping is more stable and reliable. The first hydraulic cylinder 9 and the second hydraulic cylinder 7 are alternately arranged along the length direction of the measured rail 3, and the interval is the same, so that the stress point is stable and reliable.
[0028] The magnetic table base 6 is arranged on the slider 5, and the lever micrometer 4 is fixed on the magnetic table base 6.
[0029] The magnetic table base 6 is fixed on the slider 5, so that the installation and replacement of the lever micrometer 4 are facilitated, and the machining efficiency is improved.
[0030] Specific working process:
[0031] The standard rail 2 and the slider 5 are installed on a rail station of the marble platform 1, and the lever micrometer 4 is installed on the slider 5.
[0032] In actual measurement, the measured rail 3 is placed on another rail station, and then the first hydraulic cylinder 9 is started from one end of the measured rail 3 to the other end, and then the second hydraulic cylinder 7 is started in sequence, so that the measured rail 3 is clamped and kept in a stable state.
[0033] The slider 5 on the standard rail 2 is adjusted, the slider 5 is moved to one end of the standard rail 2, the measuring end of the lever micrometer 4 on one of the sliders 5 is moved to the end face of one end of the measured rail 3, and the measuring end of the lever micrometer 4 on the other slider 5 is moved to the raceway of one end of the measured rail 3. At the same time, the readings of the two lever micrometers 4 are adjusted to "0".
[0034] The slider 5 is slowly pushed on the standard rail 2 until the measuring end of the lever micrometer 4 moves to the other end of the measured rail 3, and the difference between the maximum value and the minimum value of the reading of the lever micrometer 4 in contact with the side of the measured rail 3 during the whole process is the installation side straightness of the measured rail 3. The difference between the maximum value and the minimum value of the reading of the lever micrometer 4 in contact with the raceway of the measured rail 3 is the comprehensive straightness of the measured rail 3.
[0035] The first hydraulic cylinder 9 and the second hydraulic cylinder 7 are used to fix the measured rail 3, which can effectively improve the detection efficiency and solve the problem of frequent disassembly and assembly of the measured rail 3.
