[0005] Beneficial effect: The present application sets a first mandrel and a spiral connection with the fixed plate, so that by adjusting the first mandrel, the height of the fixed seat in the vertical direction can be adjusted, so that the second bearing connected to the fixed seat can adapt to the guide rail surfaces of different heights, thereby improving the versatility of the guide rail detection device. At the same time, the second bearing and the L-shaped slider can perform span detection on the guide rail surface at different positions of the guide rail. The L-shaped slider can synchronously drive the second bearing to slide along the guide rail surface under the drive of the driving member. The level meter detects the levelness of the bracket and thus indirectly detects the levelness of the guide rail surface, which can improve the accuracy of the detection result.

[0016] See also Figure 1 In one embodiment of the present application, a guide rail detection device 100 is provided, and the guide rail detection device 100 includes a bracket 101, an L-shaped slider 102, a fixing plate 103, a first spindle 104, and a first bearing 105 (see Figure 4 , and combined with Figure 3 IV in the figure), fixed seat 106, second spindle 107, second bearing 108, driving member (not shown) and level 109. Among them, the bracket 101 is used as a supporting component of the entire guide rail detection device 100, and is used to connect the L-shaped slider 102 and the fixed plate 103 respectively. The first spindle 104 is rotatably connected to the fixed plate 103, and is connected to the fixed seat 106 through the first bearing 105, so as to adjust the position of the fixed seat 106 in the vertical direction Y while rotating, so as to further adjust the height of the second bearing 108 that can rotate relative to the fixed seat 106, so that the driving member drives the L-shaped slider 102 to move, and simultaneously drives the second bearing 108 to rotate around the second spindle 107, and moves on different guide rail surfaces of the guide rail 200, and cooperates with the level 109 on the bracket 101 to detect the horizontality of the guide rail surface.

[0017] In this embodiment, combined with Figure 2 The guide rail 200 includes guide surface A, guide surface B, guide surface C, guide surface D, guide surface E and guide surface F which are arranged at intervals. In the guide rail 200, the guide surface A and the guide surface B are required to be perpendicular, that is, in the detection process of the guide rail 200, the guide surface A and the guide surface B are used as reference surfaces, so as to meet the following detection requirements: the guide surface C, the guide surface D, the guide surface E and the guide surface F have parallelism and perpendicularity requirements with the guide surface A and the guide surface B respectively, and the guide surface A is coplanar with the guide surface C, and the guide surface E is coplanar with the guide surface F. The guide rail detection device 100 in the present application is used to detect the parallelism and perpendicularity between the above-mentioned guide surfaces.

[0018] Please also read Figure 2 , Figure 3 and Figure 4 , and combined Figure 3 Part IV, in which, Figure 3 for Figure 1 Specifically, the bracket 101 includes a first end 1011 and a second end 1012 located on opposite sides of the guide rail 200. The bracket 101 can stably cross the guide rail 200 to provide stable support for other components of the guide rail detection device 100.

[0019] In this embodiment, the bracket 101 includes a first branch 1013, a second branch 1014 and a third branch 1015, wherein the first branch 1013 is horizontally arranged, the second branch 1014 and the third branch 1015 are respectively arranged on both sides of the first branch 1013, and are arranged in parallel between the second branch 1014 and the third branch 1015. The first end 1011 is arranged at one end of the second branch 1014 away from the first branch 1013, and the second end 1012 is arranged at one end of the third branch 1015 away from the first branch 1013.

[0020] It is understandable that the second branch 1014 and the first branch 1013, and the third branch 1015 and the first branch 1013 can be arranged vertically or inclined, depending on the extension direction of the guide surface to be detected, and no limitation is made here.

[0021] The L-shaped slider 102 is connected to the first end 1011 of the bracket 101, and the driving member is used to drive the L-shaped slider 102 to slide. The driving member controls the L-shaped slider 102 to slide along the guide rail 200, so as to achieve a comprehensive detection of the guide rail 200 in the length direction. In this embodiment, since the guide rail surface A and the guide rail surface B are used as reference surfaces, the guide rail surface A and the guide rail surface B are perpendicular to each other, and at this time, the L-shaped slider 102 is in contact with the guide rail surface A and the guide rail surface B at the same time.

[0022] It is understandable that the driving member can be manual (such as a hand wheel) or automatic (such as a motor) to push the L-shaped slider 102 to slide along the guide rail 200.

[0023] The fixing plate 103 is fixedly connected to the second end 1012 of the bracket 101 and is provided with a first threaded hole 1031. The first mandrel 104 extends along the vertical direction Y, and the first mandrel 104 passes through the fixing plate 103 through the first threaded hole 1031 and is screwed to the fixing plate 103. The first bearing 105 is located on the side of the fixing plate 103 away from the bracket 101, and the first bearing 105 is sleeved on the first mandrel 104. The fixing seat 106 is rotatably connected to the first mandrel 104 through the first bearing 105.

[0024] The fixing plate 103 is threadedly connected to the first core shaft 104 as a fixing component. When one end of the first core shaft 104 rotates relative to the fixing plate 103, the other end can rotate relative to the fixing seat 106 around the first bearing 105, thereby changing the height of the fixing seat 106 in the vertical direction Y without driving the fixing seat 106 to rotate.

[0025] The second mandrel 107 extends along the horizontal direction X, and the second mandrel 107 is fixedly connected to the fixing seat 106 . The second bearing 108 is sleeved on the second mandrel 107 , and the circumferential surface of the second bearing 108 is used to contact the guide surface of the guide rail 200 .

[0026] When the first mandrel 104 adjusts the height of the fixing seat 106 in the vertical direction Y, it simultaneously drives the height of the second bearing 108 sleeved on the second mandrel 107, so that the second bearing 108 can adapt to the guide rail surfaces of different heights. The second bearing 108 can roll on the guide rail surface, reducing the friction between the second bearing 108 and the guide rail surface while improving the smoothness of the detection process.

[0027] In this embodiment, the circumferential surface of the second bearing 108 is used to contact the guide rail surface C of the guide rail 200 .

[0028] The level 109 is connected to the bracket 101 and is used to detect the levelness of the bracket 101. The level 109 is arranged on the first branch 1013 and is used to detect and adjust the levelness of the bracket 101 when it is placed on the guide rail 200.

[0029] During the inspection process, the entire bracket 101 is placed on the guide rail 200, and the L-shaped slider 102 contacts the guide rail surface A and the guide rail surface B, and the second bearing 108 contacts the guide rail surface C. At this time, observe whether the reading of the level 109 on the bracket 101 is at the preset value (the preset value can be zero). If the reading is at the preset value, there is no need to adjust the height of the second bearing 108. If the reading is not at the preset value, it indicates that the bracket 101 is in a tilted state at this time, and it is necessary to rotate the first spindle 104 so that the first spindle 104 drives the fixed seat 106 to move in the vertical direction Y while rotating relative to the fixed plate 103, thereby further driving the second spindle 107 connected to the fixed seat 106 and the second bearing 108 on the second spindle 107 to move until the reading of the level 109 is at the preset value. During the adjustment process, it is necessary to ensure that the second bearing 108 is always in contact with the guide rail surface C.

[0030] After adjusting the position of the second bearing 108, the driving member drives the L-shaped slider 102 to move. At this time, the L-shaped slider 102 and the second bearing 108 move synchronously. During the movement, if there is an uneven position in the guide surface C that contacts the second bearing 108, the second bearing 108 will move in the vertical direction Y, thereby changing the reading of the level meter 109, indirectly detecting that there is a problem with the levelness between the guide surface C and the guide surface A of the guide rail 200.

[0031] In the above-mentioned guide rail detection device 100, the position of the first mandrel 104 can be adjusted by setting the first mandrel 104 and the fixed plate 103 to be spirally connected, thereby adjusting the height of the fixed seat 106 in the vertical direction Y, so that the second bearing 108 connected to the fixed seat 106 can adapt to guide rail surfaces of different heights, thereby improving the versatility of the guide rail detection device 100. At the same time, the second bearing 108 and the L-shaped slider 102 can perform span detection on the guide rail surface at different positions of the guide rail 200. The L-shaped slider 102 can synchronously drive the second bearing 108 to slide along the guide rail surface under the drive of the driving member. The level meter 109 detects the levelness of the bracket 101 and thus indirectly detects the levelness of the guide rail surface, which can improve the accuracy of the detection result.

[0032] See also Figure 3 and Figure 5 In one embodiment, one end of the first spindle 104 close to the fixing plate 103 extends out of the fixing plate 103 and is exposed outside the second end 1012 of the bracket 101 to facilitate an operator to rotate the first spindle 104 .

[0033] Please also read Figure 3 , Figure 4 and Figure 5In one embodiment, the guide rail detection device 100 further includes a baffle 110 and an adjusting member 111. The baffle 110 is erected on the side of the fixing seat 106 away from the guide rail 200, and the baffle 110 is connected to the fixing plate 103. The baffle 110 is provided with a second threaded hole 1101. The adjusting member 111 passes through the baffle 110 through the second threaded hole 1101 and abuts against the fixing seat 106. By limiting the fixing seat 106 at a preset position by the adjusting member 111, the rotation of the fixing seat 106 caused by external force or vibration during the detection process can be effectively avoided, thereby improving the stability of the overall device.

[0034] In one embodiment, the adjusting member 111 is generally an adjusting screw or other length-adjustable parts.

[0035] It is understandable that since the adjustment member 111 does not need to be completely locked with the fixed base 106, it only needs to limit the rotation of the fixed base 106. Therefore, the adjustment member 111 can abut against the side wall of the fixed base 106 before adjusting the height of the fixed base 106 in the vertical direction Y, or it can abut against the side wall of the fixed base 106 after adjusting the height of the fixed base 106 in the vertical direction Y. There is no limitation here.

[0036] In one embodiment, a plurality of adjusting members 111 may be provided, and the plurality of adjusting members 111 are simultaneously pressed against the side wall of the fixing base 106 , thereby further reducing the risk of the fixing base 106 rotating.

[0037] Please also read Figure 3 and Figure 4 In one embodiment, the fixing seat 106 is provided with a limiting groove 1061, and the first bearing 105 is limited in the limiting groove 1061. By providing the limiting groove 1061, the risk of displacement of the first bearing 105 during use is reduced, so that the first spindle 104 is more stable and reliable when rotating to adjust the height of the fixing seat 106 in the vertical direction Y.

[0038] In this embodiment, the first bearing 105 is a deep groove ball bearing.

[0039] Please continue reading Figure 3 and Figure 4In one embodiment, the fixed seat 106 includes a first connection portion 1062, a second connection portion 1063 and a seat body 1064. The first connection portion 1062 and the second connection portion 1063 are distributed on both sides of the second bearing 108 along the horizontal direction X, and are both fixedly connected to the second mandrel 107. The seat body 1064 connects the first connection portion 1062 and the second connection portion 1063, and the seat body 1064 is provided with a limiting groove 1061. Through the above arrangement, the seat body 1064, as the main structure of the fixed seat 106, provides the main support for the second bearing 108, and also ensures the position of the first bearing 105 is fixed through the limiting groove 1061 to prevent the first bearing 105 from shifting during use. At the same time, the design of the first connection portion 1062 and the second connection portion 1063 strengthens the lateral stability of the fixed seat 106. The second mandrel 107 connects the first connection portion 1062 and the second connection portion 1063, which can improve the stability of the second bearing 108 during the detection process.

[0040] In one embodiment, the first connection portion 1062 , the second connection portion 1063 and the base body 1064 are integrally formed to improve the structural strength of the entire fixing base 106 .

[0041] In other embodiments, the first connection portion 1062 , the second connection portion 1063 , and the seat body 1064 may also be assembled as separate parts into a whole fixing seat 106 , which is not limited here.

[0042] In this embodiment, the second bearing 108 is a deep groove ball bearing.

[0043] Please continue reading Figure 3 and Figure 4 In one embodiment, the guide rail detection device 100 further includes a first retaining ring 112, which is disposed in the limiting groove 1061 and the outer ring of the first retaining ring 112 is embedded in the groove wall of the limiting groove 1061. The first retaining ring 112 abuts against the side of the first bearing 105 facing the fixed plate 103, and the end of the first spindle 104 away from the fixed plate 103 passes through the first retaining ring 112 and is rotatably connected to the first bearing 105. Through the above arrangement, the first retaining ring 112 reduces the risk of the first bearing 105 escaping from the limiting groove 1061, thereby improving the stability of the first bearing 105 in the fixed seat 106.

[0044] In one embodiment, the first retaining ring 112 is a shaft retaining ring, which is usually made of carbon spring steel or stainless steel.

[0045] Please continue reading Figure 3 and Figure 4In one embodiment, the guide rail detection device 100 further includes a second retaining ring 113, which is sleeved on the second mandrel 107 to limit the second bearing 108 between the second retaining ring 113 and the first connecting portion 1062 / the second connecting portion 1063. Through the above arrangement, the second bearing 108 can be arranged between the second retaining ring 113 and the first connecting portion 1062, or between the second retaining ring 113 and the second connecting portion 1063, thereby reducing the risk of the second bearing 108 being displaced in the horizontal direction X along the second mandrel 107 and thus being separated from the guide rail surface, so as to ensure that the second bearing 108 is always kept at a preset position during the detection process, thereby improving the accuracy and stability of the detection.

[0046] In one embodiment, the second retaining ring 113 is a shaft retaining ring, which is usually made of carbon spring steel or stainless steel.

[0047] Please continue reading Figure 3 and Figure 4 In one embodiment, the guide rail detection device 100 further includes a first locking nut 114 and a second locking nut 115. The first locking nut 114 is disposed on the side of the fixing seat 106 facing the fixing plate 103, and is sleeved on the first spindle 104. The second locking nut 115 is disposed on one side of the outer wall of the fixing seat 106, and is sleeved on the second spindle 107. Through the above arrangement, the first locking nut 114 can fix the position of the first spindle 104 relative to the fixing seat 106 to prevent it from loosening during the rotation process, and the second locking nut 115 can fix the position of the second spindle 107 relative to the fixing seat 106 to prevent it from loosening during the rotation process, thereby improving the accuracy and reliability of the detection.

[0048] Please also read Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the guide rail detection device 100 further includes a dial gauge 116, one end of which is connected to the bracket 101, and the other end is configured to contact the vertical surface of the guide rail 200 to detect the verticality of the guide rail 200. By setting the dial gauge 116, the verticality of the guide rail 200 is further detected. When the bracket 101 is offset, that is, the reading of the dial gauge 116 changes, indicating that the vertical surface of the guide rail 200 has an uneven position.

[0049] Specifically, one end of the micrometer 116 is connected to the bracket 101 through a clamp (not shown) or a fixing member (not shown), and the probe of the micrometer 116 (not shown) contacts the vertical surface of the guide rail 200. The probe of the micrometer 116 is usually designed to be spherical or other shapes that can fit well with the surface of the guide rail 200 to ensure the uniformity and stability of the micrometer 116 during the contact process with the vertical surface of the guide rail 200, thereby improving the accuracy of the guide rail 200 detection process.

[0050] In this embodiment, one end of the micrometer 116 is connected to the second branch 1014 of the bracket 101, and the other end contacts the guide surface D, so as to detect the verticality between the guide surfaces C and D, and also detect the horizontality between the guide surfaces B and D.

[0051] Please continue reading Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the L-shaped slider 102 includes a first sliding portion 1021 and a second sliding portion 1022. The first sliding portion 1021 extends along the horizontal direction X and is configured to cooperate with the bracket 101, the second bearing 108, and the level 109 to detect the horizontality of the guide rail 200. One end of the second sliding portion 1022 is connected to the first sliding portion 1021, and the other end extends along the vertical direction Y, and is configured to cooperate with the bracket 101 and the micrometer 116 to detect the verticality of the guide rail 200. Through the above arrangement, the first sliding portion 1021 can ensure that the entire guide rail detection device 100 can slide smoothly on the guide rail 200, and the second sliding portion 1022 makes the micrometer 116 more stable when detecting verticality, and will not be offset due to external force or vibration.

[0052] In this embodiment, the first sliding portion 1021 contacts the guide rail surface A as a reference surface, and the second sliding portion 1022 contacts the guide rail surface B as a reference surface.

[0053] Specifically, when the first sliding part 1021 cooperates with the bracket 101, the second bearing 108, and the spirit level 109 to detect the horizontality of the guide rail 200, the first sliding part 1021 contacts the guide rail surface A, and the second bearing 108 contacts the guide rail surface C. When the L-shaped slider 102 moves along the length direction of the guide rail 200 driven by the driving member, the bracket 101 and the second bearing 108 move synchronously. At this time, if the guide rail surface C has an uneven position, the position of the second bearing 108 will change in the vertical direction Y, thereby causing the bracket 101 to tilt. At this time, the reading of the spirit level 109 changes, indicating that there is a non-coplanar position between the guide rail surfaces A and C.

[0054] Specifically, when the second sliding portion 1022 cooperates with the bracket 101 and the micrometer 116 to detect the verticality of the guide rail 200, the second sliding portion 1022 contacts the guide rail surface B, and the probe of the micrometer 116 contacts the guide rail surface D. When the L-shaped slider 102 moves along the length direction of the guide rail 200 driven by the driving member, the bracket 101 and the second bearing 108 move synchronously. At this time, if the guide rail surface D is uneven, the position of the second bearing 108 will change in the horizontal direction X, causing the bracket 101 to tilt. At this time, the readings of the spirit level 109 and the micrometer 116 will change, indicating that there is a non-coplanar position between the guide rail surface B and the guide rail surface D, and there is also a problem with the verticality between the indirect surface guide surface C and the guide rail surface D.

[0055] Please also read Figure 3 and Figure 6 In one embodiment, a plurality of exhaust grooves 1023 are concavely formed on one side of the L-shaped slider 102 away from the first end 1011. The main function of the exhaust grooves 1023 is to discharge the air accumulated under the slider during the sliding process of the slider, reduce air resistance, and thus improve the sliding smoothness of the slider on the guide rail 200. At the same time, the exhaust grooves 1023 can also absorb the vibration generated during the sliding process to a certain extent, reduce the friction noise between the slider and the guide rail 200, and improve the smoothness of the sliding.

[0056] In one embodiment, the plurality of exhaust grooves 1023 may be arranged in parallel on the surface of the L-shaped slider 102 , or may be arranged crosswise and vertically on the surface of the L-shaped slider 102 , or may be arranged on the surface of the L-shaped slider 102 in a combination of the above two methods, which is not limited here.

[0057] In this embodiment, the exhaust groove 1023 is rectangular in shape, and a plurality of rectangular exhaust grooves 1023 are cross-arranged vertically and horizontally on the surface of the L-shaped slider 102. In other embodiments, the exhaust groove 1023 may also be circular or other suitable geometric shapes, which are not limited here.

[0058] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the detection process of the guide rail detection device 100 includes:

[0059] First, place the bracket 101 above the guide rail 200, make the first sliding part 1021 contact the guide rail surface A, and the second sliding part 1022 contact the guide rail surface B, and indirectly adjust the height of the second bearing 108 through the first core shaft 104 so that the circumferential surface of the second bearing 108 contacts the guide rail surface C, and the probe of the micrometer 116 contacts the guide rail surface D.

[0060] Next, before testing, confirm that the readings of the level meter 109 and the dial gauge 116 are both at preset values.

[0061] Finally, the driving member drives the L-shaped slide to move. At this time, the readings of the level 109 and the micrometer 116 are observed to confirm whether the guide surfaces A and C are coplanar, and whether the guide surfaces C and D meet the parallelism and perpendicularity requirements with the guide surfaces A and B respectively.

[0062] It can be understood that in order to determine whether the guide surface E and the guide surface F in the guide rail 200 are coplanar, whether the guide surface E and the guide surface B are perpendicular, and whether the guide surface F and the guide surface D meet the parallelism and perpendicularity requirements with the guide surface E and the guide surface B respectively, it is only necessary to flip the entire guide rail 200 over and repeat the above steps to test.

[0063] The above are only implementation methods of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
