[0039] Referring to Figure 1 , Figure 2 and Figure 3As shown, the rail measuring device 10 related to the embodiments of the present application is used for measuring the rail 20, the rail 20 has a first direction x, a second direction y and a third direction z, the first direction x, the second direction y and the third direction z are mutually intersected, the rail 20 includes a base 21, a first track 22 and a second track 23, the first track 22 and the second track 23 are both arranged on one end of the base 21 along the third direction z and are spaced apart along the first direction x, and are both arranged to extend along the second direction y, the rail measuring device 10 includes a housing 100, a reference assembly 200, a first measuring piece 300, a clamping assembly 400 and a second measuring piece 500.

[0040] Specifically, the reference assembly 200 is at least partially used for abutting the base 21 away from one end of the first track 22 and the second track 23 along the third direction z; the first measuring piece 300 is connected with the housing 100 and has a first measuring part 310 and a first main body part 320, the first measuring part 310 is arranged at one end of the first main body part 320 close to the reference assembly 200 along the third direction z, and one end of the first measuring part 310 away from the first main body part 320 along the third direction z abuts against the reference assembly 200, the first measuring part 310 can move relative to the first main body part 320 along the third direction z; the clamping assembly 400 includes a first clamping piece 410 and a second clamping piece 420, the first clamping piece 410 and the second clamping piece 420 are both connected with the housing 100 and are arranged spaced apart along the first direction x, the second clamping piece 420 can slide relative to the housing 100 along the first direction x, the first clamping piece 410 is used for abutting the first track 22, and the second clamping piece 420 is used for abutting the second track 23; the second measuring piece 500 is connected with the housing 100 and is used for measuring the moving distance of the second clamping piece 420 along the first direction x.

[0041] It should be noted that the rail 20 is usually manufactured by using a grinding process, that is, the track is precisely machined by a grinding wheel to achieve the required profile accuracy and surface quality. However, during the grinding process, the grinding wheel will gradually wear out due to the continuous friction between the grinding wheel and the steel rail, which will cause the shape and size of the grinding wheel to change. This wear not only affects the profile consistency of different rails 20 in the same batch, but also may cause the center distance of the rails 20 at different positions to deviate. Therefore, during the manufacturing process of the rail 20, the profile consistency of the rail 20 needs to be detected by the rail measuring device 10 to ensure that it meets the design requirements.

[0042] It should be noted that the first direction x is the direction indicated by x in the figure, that is, the width direction of the rail 20, the second direction y is the direction indicated by y in the figure, that is, the length direction of the rail 20, and the third direction z is the direction indicated by z in the figure, that is, the height direction of the rail 20. Figure 1 Figure 1 Figure 1 ​​The direction indicated by the Z direction, i.e., the height direction of the guide rail 20, specifically, in the present embodiment, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other in pairs.

[0043] In the guide rail measuring device 10 of the present application, since the first clamping member 410 is used to abut against the first rail 22, and the second clamping member 420 is used to abut against the second rail 23, in this way, the guide rail 20 can be clamped by the first clamping member 410 and the second clamping member 420, so as to facilitate subsequent measurement of the guide rail 20 by the guide rail measuring device 10, in this process, since the first measuring member 300 and the clamping assembly 400 are both connected with the housing 100, in this way, when the clamping assembly 400 clamps the guide rail 20, the guide rail 20 can be measured in one dimension by the first measuring member 300, in the measurement process of the first measuring member 300, since the first measuring part 310 of the first measuring member 300 abuts against the reference assembly 200 along the third direction Z away from one end of the first main part 320, and can move along the third direction Z relative to the first main part 320, therefore, when measuring the guide rail 20 at different length positions, if the dimensions of the guide rail 20 at different length positions along the third direction Z, i.e., the dimensions along the height direction, are inconsistent, it will cause the first measuring part 310 to move along the third direction Z relative to the first main part 320, in this way, the consistency of the dimensions of the guide rail 20 at different length positions along the third direction Z can be determined according to the moving range of the first measuring part 310 along the third direction Z measured by the first measuring member 300, further, since the second clamping member 420 can slide along the first direction X relative to the housing 100, and the second measuring member 500 is used to measure the moving distance of the second clamping member 420 along the first direction X, therefore, the guide rail 20 can be measured in another dimension by the second measuring member 500, in the measurement process of the first measuring member 300, when measuring the guide rail 20 at different length positions, if the dimensions of the guide rail 20 at different length positions along the first direction X, i.e., the dimensions along the width direction, are inconsistent, it will cause the second clamping member 420 to slide along the first direction X relative to the housing 100, in this way, the consistency of the dimensions of the guide rail 20 at different length positions along the first direction X can be determined according to the range of the distance change of the second clamping member 420 sliding along the first direction X measured by the second measuring member 500, in summary, the guide rail measuring device 10 of the present application can measure the dimensional consistency of the guide rail 20 in multiple dimensions, so as to improve the accuracy of the consistency measurement of the guide rail 20, thereby meeting the needs of high-precision guide rail 20 manufacturing.

[0044] Specifically, in the present embodiment, the first measuring member 300 is a first digital dial gauge, the first measuring part 310 is a measuring rod of the first digital dial gauge, and the first main body part 320 is a digital display of the first digital dial gauge. The distance of the first measuring part 310 displayed by the first main body part 320 moving along the third direction z is used to determine the dimensional change of the guide rail 20 along the third direction z.

[0045] Referring to Figure 3 As shown in the figure, the first clamping member 410 includes a first connecting part 411 and a first clamping part 412. The first connecting part 411 is connected with the housing 100, and the first clamping part 412 is connected with the first connecting part 411. The first clamping part 412 is used to fit with the groove wall of the track groove of the first rail 22, and the central axis of the first clamping part 412 is used to coincide with the central axis of the track groove of the first rail 22. The second clamping member 420 includes a second connecting part 421 and a second clamping part 422. The second connecting part 421 is connected with the housing 100, and the second clamping part 422 is connected with the second connecting part 421. The second clamping part 422 is used to fit with the groove wall of the track groove of the second rail 23, and the central axis of the second clamping part 422 is used to coincide with the central axis of the track groove of the second rail 23.

[0046] In the present embodiment, the first clamping part 412 and the second clamping part 422 can be connected with the housing 100 through the first connecting part 411 and the second connecting part 421, respectively, so as to improve the structural stability of the first clamping part 412 and the second clamping part 422. Since the first clamping part 412 is used to fit with the groove wall of the track groove of the first rail 22, and the second clamping part 422 is used to fit with the groove wall of the track groove of the second rail 23, the guide rail 20 can be clamped by the cooperation of the first clamping member 410 and the second clamping member 420, so as to realize the installation of the guide rail measuring device 10 of the present application on the guide rail 20, and facilitate the subsequent measurement of the guide rail 20 by the guide rail measuring device 10 of the present application. Since the central axis of the first clamping part 412 is used to coincide with the central axis of the track groove of the first rail 22, and the central axis of the second clamping part 422 is used to coincide with the central axis of the track groove of the second rail 23, the distance between the central axis of the first clamping part 412 and the central axis of the second clamping part 422 is the distance between the central axis of the track groove of the first rail 22 and the central axis of the track groove of the second rail 23, so as to accurately measure the distance between the central axis of the track groove of the first rail 22 and the central axis of the track groove of the second rail 23, and determine the consistency of the dimensions of the guide rail 20 along the first direction x at different length positions.

[0047] Specifically, in the embodiment, when the distance between the center axis of the first clamping portion 412 and the center axis of the second clamping portion 422 is within a first preset range, it indicates that the consistency of the size of the guide rail 20 along the first direction x is qualified; wherein the first preset range is L1, which satisfies: 0≤L1≤3μm, if L1>3μm, it will cause the qualified range of the distance between the center axis of the first clamping portion 412 and the center axis of the second clamping portion 422 to be too large, so that the consistency of the size of the guide rail 20 along the first direction x is reduced, and the manufacturing precision of the guide rail 20 is reduced.

[0048] Specifically, in the embodiment, the cross section of the track groove of the first track 22 is semicircular, the cross section of the first clamping portion 412 is circular, and the diameter of the cross section of the track groove of the first track 22 is equal to the diameter of the cross section of the first clamping portion 412, so that when the first clamping portion 412 abuts against the groove wall of the track groove of the first track 22, the center axis of the first clamping portion 412 coincides with the center axis of the track groove of the first track 22; similarly, the cross section of the track groove of the second track 23 is semicircular, the cross section of the second clamping portion 422 is circular, and the diameter of the cross section of the track groove of the second track 23 is equal to the diameter of the cross section of the second clamping portion 422, so that when the second clamping portion 422 abuts against the groove wall of the track groove of the second track 23, the center axis of the second clamping portion 422 coincides with the center axis of the track groove of the second track 23.

[0049] In addition, in other embodiments, the cross section of the track groove of the first track 22 is rectangular, the cross section of the first clamping portion 412 is rectangular, and the rectangular profile size of the cross section of the track groove of the first track 22 is the same as the rectangular profile size of the cross section of the first clamping portion 412, so that when the first clamping portion 412 abuts against the groove wall of the track groove of the first track 22, the center axis of the first clamping portion 412 coincides with the center axis of the track groove of the first track 22; similarly, the cross section of the track groove of the second track 23 is rectangular, the cross section of the second clamping portion 422 is rectangular, and the rectangular profile size of the cross section of the track groove of the second track 23 is the same as the rectangular profile size of the cross section of the second clamping portion 422, so that when the second clamping portion 422 abuts against the groove wall of the track groove of the second track 23, the center axis of the second clamping portion 422 coincides with the center axis of the track groove of the second track 23.

[0050] In addition, in other embodiments, the cross section of the track groove of the first track 22 can also be triangular, elliptical, polygonal or other shapes, and the cross section of the first clamping portion 412 corresponds to the shape of the cross section of the track groove of the first track 22, so that the central axis of the first clamping portion 412 coincides with the central axis of the track groove of the first track 22; the cross section of the track groove of the second track 23 can also be triangular, elliptical, polygonal or other shapes, and the cross section of the second clamping portion 422 corresponds to the shape of the cross section of the track groove of the second track 23, so that the central axis of the second clamping portion 422 coincides with the central axis of the track groove of the second track 23.

[0051] Specifically, in the present embodiment, the shape of the cross section of the track groove of the first track 22 can be the same as or different from the shape of the cross section of the track groove of the second track 23, but the shape of the cross section of the first clamping portion 412 needs to correspond to the shape of the cross section of the track groove of the first track 22, and the shape of the cross section of the second clamping portion 422 needs to correspond to the shape of the cross section of the track groove of the second track 23, so as to ensure that the central axis of the first clamping portion 412 coincides with the central axis of the track groove of the first track 22, and ensure that the central axis of the second clamping portion 422 coincides with the central axis of the track groove of the second track 23.

[0052] Referring to Figure 4 As shown in the figure, the guide rail measuring device 10 further comprises a sliding assembly 600, the sliding assembly 600 comprises a guide piece 610 and a sliding piece 620, the guide piece 610 is connected with the housing 100 and extends along the first direction x, the second clamping piece 420 is connected with the sliding piece 620, and the sliding piece 620 is slidingly connected with the guide piece 610 and slides along the first direction x relative to the guide piece 610.

[0053] Specifically, in the present embodiment, the second clamping piece 420 slides along the first direction x relative to the housing 100.

[0054] In the present embodiment, since the guide piece 610 is connected with the housing 100, the second clamping piece 420 is connected with the sliding piece 620, the sliding piece 620 is slidingly connected with the guide piece 610 and slides along the first direction x relative to the guide piece 610, so when the sliding piece 620 slides along the first direction x relative to the guide piece 610, the second clamping piece 420 can be driven by the sliding piece 620 to slide along the first direction x relative to the guide piece 610, so that the second clamping piece 420 slides along the first direction x relative to the housing 100, and further so that the second clamping piece 420 slides along the first direction x relative to the first clamping piece 410, so that the distance between the first clamping piece 410 and the second clamping piece 420 can change with the distance between the first track 22 and the second track 23.

[0055] Referring to Figure 3 and Figure 4 As shown in FIG. 4, the second measuring member 500 has a second measuring portion 510 and a second main body portion 520, the second measuring portion 510 is connected with the second main body portion 520, and an end of the second measuring portion 510 away from the second main body portion 520 abuts against the second clamping member 420, and the second measuring portion 510 is movable relative to the second main body portion 520 along the first direction x.

[0056] Specifically, in the present embodiment, the second measuring member 500 is a second digital dial micrometer, the second measuring portion 510 is a measuring rod of the second digital dial micrometer, and the second main body portion 520 is a digital display table of the second digital dial micrometer, and the distance of the second measuring portion 510 displayed by the second main body portion 520 along the first direction x is used to determine the distance change between the first rail 22 and the second rail 23 along the first direction x.

[0057] In the present embodiment, when the guide rail 20 at different length positions is measured, if the distance between the first rail 22 and the second rail 23 along the first direction x changes, the second clamping member 420 will be displaced along the first direction x. Since the end of the second measuring portion 510 away from the second main body portion 520 abuts against the second clamping member 420, and the second measuring portion 510 is movable relative to the second main body portion 520 along the first direction x, when the second clamping member 420 is displaced along the first direction x, the second clamping member 420 will push the second measuring portion 510 to move along the first direction x, so that the distance change between the first rail 22 and the second rail 23 along the first direction x can be reflected by the movement of the second measuring portion 510 along the first direction x.

[0058] Referring to Figure 4 As shown in FIG. 4, the clamping assembly 400 further comprises a resilient connecting member 430, the second measuring portion 510 and the first clamping member 410 are arranged at the same end of the second clamping member 420 along the first direction x, the resilient connecting member 430 is arranged at the other end of the second clamping member 420 along the first direction x, and the two ends of the resilient connecting member 430 are connected with the housing 100 and the second clamping member 420 respectively, and the resilient connecting member 430 has a resilient potential energy along the first direction x.

[0059] Specifically, in the present embodiment, the resilient connecting member 430 is a spring, the two ends of the spring are connected with the housing 100 and the second clamping member 420 respectively, and the spring is capable of stretching and contracting along the first direction x.

[0060] In the embodiment, since the second measuring part 510 and the first clamping part 410 are arranged at the same end of the second clamping part 420 along the first direction x, the elastic connecting part 430 is arranged at the other end of the second clamping part 420 along the first direction x, and the two ends of the elastic connecting part 430 are connected with the shell 100 and the second clamping part 420 respectively, thus, when the first clamping part 410 and the second clamping part 420 clamp the guide rail 20, the elastic connecting part 430 can provide a pushing force for the second clamping part 420 to move along the first direction x towards the first clamping part 410, so as to improve the clamping and fastening force of the first clamping part 410 and the second clamping part 420 on the guide rail 20, and at the same time, the elastic connecting part 430 and the second measuring part 510 can be abutted at the two ends of the second clamping part 420 along the first direction x respectively, so as to ensure that the second measuring part 510 can always be kept in abutment with the second clamping part 420, thereby improving the measurement accuracy of the second measuring part 500.

[0061] Referring to Figure 3 and Figure 4 As shown in the figures, the clamping assembly 400 further comprises a first handle 440, which is connected with the second clamping part 420 and moves along the first direction x relative to the shell 100.

[0062] In the embodiment, since the first handle 440 is connected with the second clamping part 420 and moves along the first direction x relative to the shell 100, thus, when the guide rail measuring device 10 of the present application is installed on the guide rail 20, the first handle 440 can be pushed along the first direction x towards the direction away from the first clamping part 410, so that the second clamping part 420 moves along the first direction x towards the direction away from the first clamping part 410, so that the space between the first clamping part 410 and the second clamping part 420 can accommodate the first rail 22 and the second rail 23, and then the first handle 440 is released, so that the second clamping part 420 is pushed by the elastic connecting part 430 to move along the first direction x towards the direction away from the first clamping part 410, so that the first clamping part 410 and the second clamping part 420 clamp the first rail 22 and the second rail 23, thereby completing the installation of the guide rail measuring device 10 of the present application. Similarly, when it is necessary to disassemble the guide rail measuring device 10 of the present application from the guide rail 20, the above operation can be repeated, thus, the guide rail measuring device 10 of the present application has the advantages of convenient installation and flexible movement, so as to improve the efficiency of measuring the guide rail 20 and meet the needs of measuring long guide rails 20.

[0063] Referring to Figure 4 As shown in the figures, the shell 100 is provided with a relief hole 110 extending along the first direction x, and the first handle 440 is arranged in the relief hole 110 and moves along the first direction x relative to the relief hole 110.

[0064] In the embodiment, the first handle 440 is arranged in the avoiding hole 110 and moves relative to the avoiding hole 110 along the first direction x, so that the movement of the first handle 440 can be avoided by the avoiding hole 110, and the movement of the first handle 440 is not interfered by the shell 100. In addition, the avoiding hole 110 extends along the first direction x, so that the movement of the first handle 440 can be guided by the avoiding hole 110 when the first handle 440 is pushed to move along the first direction x, and the movement of the first handle 440 along the first direction x is ensured, thereby improving the smoothness of the movement of the second clamping part 420 along the first direction x.

[0065] Referring to Figure 3 and Figure 4 As shown in the figures, the clamping assembly 400 further comprises a second handle 450, the second handle 450 is arranged apart from the first handle 440 along the first direction x, and the second handle 450 is connected with the shell 100.

[0066] In the embodiment, when the first handle 440 is moved along the first direction x to the direction away from the first clamping part 410, the elastic connecting part 430 will apply resistance to the first handle 440. Since the second handle 450 is arranged apart from the first handle 440 along the first direction x, and the second handle 450 is connected with the shell 100, at this time, the operator can hold the second handle 450 and the first handle 440 by hand, so as to provide support force and pulling force to the first handle 440 through the second handle 450, thereby offsetting part of the resistance applied to the first handle 440 by the elastic connecting part 430, so as to reduce the difficulty of the movement of the first handle 440 along the first direction x.

[0067] Referring to Figure 2 As shown in the figures, the reference assembly 200 comprises a first reference part 210 and a second reference part 220. The first reference part 210 is used to abut the bottom 21 away from one side of the first track 22 and the second track 23 along the third direction z. The second reference part 220 is connected with the first reference part 210 on one side along the third direction z, and is used to be located on the same side of the bottom 21 as the first reference part 210 along the third direction z. The first measuring part 310 is abutted with the second reference part 220 on one end away from the first main part 320 along the third direction z.

[0068] In the embodiment, the first reference member 210 is used to abut against the base 21 on the side away from the first rail 22 and the second rail 23 along the third direction z, the second reference member 220 is connected to the first reference member 210 on the side along the third direction z, and is used to be located on the same side of the base 21 as the first reference member 210 along the third direction z. In this way, the second reference member 220 can be provided with a reference surface by the first reference member 210, so that the second reference member 220 can be located on the same plane as the base 21. Since the first measuring portion 310 is abutted against the second reference member 220 on the end of the first main body portion 320 away from the third direction z, when the guide rail 20 at different length positions is measured, if the distance between the connecting line between the center axis of the first rail 22 and the center axis of the second rail 23 and the plane of the base 21 close to the first reference member 210 along the third direction z changes, that is, the height of the first rail 22 and the second rail 23 changes, the first measuring portion 310 will move along the third direction z relative to the first main body portion 320, so as to determine the consistency of the size of the guide rail 20 along the third direction z at different length positions by the range of the moving distance of the first measuring portion 310.

[0069] Specifically, in the embodiment, when the range of the distance between the connecting line between the center axis of the first rail 22 and the center axis of the second rail 23 and the plane of the base 21 close to the first reference member 210 along the third direction z changes is within the second preset range, it indicates that the consistency of the size of the guide rail 20 along the third direction z is qualified; wherein the second preset range is L2, and satisfies: 0≤L2≤3μm. If L2>3μm, the second preset range will be too large, so that the consistency of the size of the guide rail 20 along the third direction z will be reduced, and the manufacturing precision of the guide rail 20 will be reduced.

[0070] The guide rail 20 manufacturing device related to the embodiment includes the guide rail measuring device 10 described above.

[0071] In the guide rail 20 manufacturing device of the application, since the guide rail measuring device 10 of the application can improve the accuracy of the consistency measurement of the guide rail 20, the manufacturing precision of the guide rail 20 manufacturing device of the application can be improved, so as to improve the finished product precision and quality of the guide rail 20.
