An aperture detection apparatus for mounting rails

Abstract

This application discloses a bore diameter testing device for mounting rails, relating to the field of mounting rail quality inspection. It includes a base plate with a switching mechanism on its top. The device utilizes a rotating column to drive a connecting cylinder to rotate, which in turn drives the connecting column to rotate, thereby rotating a rotating shaft via a worm gear. This allows for the switching between testing component one and testing component two. Therefore, when testing mounting rails with different bore diameters, there is no need to disassemble or replace the device. The testing components for the different mounting rails to be tested are pre-installed on both sides of the connecting block, simplifying the work process and improving the ability to test the bore diameter of different mounting rails simply by switching some parts. Compared to a single press-type bore diameter testing component, this device does not require customized devices for different bore diameters, nor does it require disassembly and reassembly of the entire device for changing bore diameters. Switching is completed simply by switching between testing component one and testing component two, resulting in a wider range of applications and more convenient operation.

Description

Technical Field

[0001] This application relates to the field of installation rail quality inspection, and in particular to an installation rail bore diameter inspection device. Background Technology

[0002] Mounting rails are used to fix the trajectory of mobile devices, which facilitates the movement of the devices and improves their stability. The holes and diameters of the mounting rails need to be kept in a uniform specification to facilitate the installation of the devices and the fixation of the mounting rails in actual use scenarios.

[0003] Currently, the hole diameter testing equipment for mounting rails uses a one-hole-one-component approach. The equipment can only test the hole diameter of a certain specification of mounting rail. However, in actual production, the hole diameter of the mounting rail varies depending on the production requirements and different models, or it needs to be changed in real time. In this case, in order to test the hole diameter of different hole positions during production, the entire testing device needs to be changed continuously. The applicable environment of the device is small, and the replacement method is cumbersome, which is not conducive to the requirement of rapid replacement in automated production lines. Utility Model Content

[0004] To improve the problem of inconsistent testing methods, this application provides a device for detecting the aperture of an installation rail.

[0005] The mounting rail bore diameter detection device provided in this application adopts the following technical solution:

[0006] A bore diameter detection device for mounting rails includes a device base plate, and a switching mechanism is provided on the top of the device base plate;

[0007] The switching mechanism includes a support frame fixedly mounted on the top of the device base plate. A cylinder is mounted on the top of the support frame to drive the connecting plate to move vertically. A rotating shaft is mounted below the connecting plate to drive the connecting block to rotate axially. Detection component one and detection component two are symmetrically arranged on the outer wall of the connecting block. A rotating column is mounted on the top of the device base plate to drive the connecting cylinder to rotate. A connecting column is mounted at the bottom of the connecting cylinder to drive the worm gear to rotate. The worm gear rotates synchronously with the rotating shaft.

[0008] By adopting the above technical solution, the connecting plate can drive the second detection component to move vertically downward, thereby completing the detection of the aperture. The first detection component and the second detection component are located in the same rotation path. The longitudinal position of the first detection component and the second detection component can be swapped by the rotating shaft, thereby switching functions and realizing the specification detection of different apertures.

[0009] Preferably, the switching mechanism further includes a sliding block fixedly connected to the bottom output shaft end of the cylinder; the bottom of the support frame is fixedly connected to the top of the device base plate; the top of the support frame is fixedly connected to the outer wall of the cylinder; a drive column is fixedly connected to the bottom of the sliding block; a fixing ring movably passes through the outer wall of the drive column; a spring is fixedly connected to the top of the fixing ring and fixedly connected to the bottom of the sliding block; a limiting cylinder is fixedly connected to the outer wall of the fixing ring and fits against the outer wall of the sliding block; an upper housing is fixedly connected to the top of the limiting cylinder and fits against the outer wall of the sliding block; a lower housing is fixedly connected to the bottom of the upper housing; a connecting plate is fixedly connected to the bottom of the drive column; vertical plates are fixedly connected to both ends of the connecting plate; and a limiting plate is fixedly connected to the outer wall of the vertical plate.

[0010] By adopting the above technical solution, when the sliding block moves vertically downwards, it will compress the first spring, thereby buffering the vertical movement of the sliding block through the first spring. This makes the insertion of the second detection component and the mounting rail smoother, thus avoiding damage to the mounting rail caused by the second detection component.

[0011] Preferably, the outer wall of the limiting plate is provided with a clamping plate that is fixedly connected to the inner wall of the upper housing, the side wall of the vertical plate is movably penetrated by a rotating shaft, the outer wall of the rotating shaft is fixedly penetrated by a connecting block one, the upper and lower sides of the connecting block one are fixedly connected to the connecting block two, the end of the connecting block two away from the connecting block one is fixedly connected to the bottom of the detection component one, and the top of the detection component two is fixedly connected to the bottom of the connecting block two.

[0012] By adopting the above technical solution, the connecting block 2 makes the detection component 1 and the detection component 2 and the connecting block 1 have a certain distance, so that when the detection component 2 is fully inserted into the top of the installation rail for detection, there is a gap between the bottom of the vertical plate and the top of the installation rail, thereby avoiding damage to the top of the installation rail by the vertical plate.

[0013] Preferably, a knob that fits against the top of the upper housing is fixedly connected to the top of the rotating column, a sealing cover is movably passed through the outer wall of the rotating column, a sliding disc is movably passed through the outer wall of the rotating column, a limiting block 1 that is slidably connected to the outer wall of the sliding disc is fixedly connected to the outer wall of the sliding disc, and a spring 2 is fixedly connected to the bottom of the sliding disc.

[0014] By adopting the above technical solution, the limiting block one is symmetrically located on the outer wall of the sliding disk in a ring, which makes the limiting block one on the sliding disk more stable. The spring two maintains a distance of - mm from the inner wall of the connecting cylinder and the outer wall of the rotating column, thereby avoiding damage to the outer wall of the structural components.

[0015] Preferably, the bottom of the second spring is fixedly connected to a fixed disk that is fixedly connected to the bottom of the rotating column, the outer wall of the fixed disk is fixedly connected to a limiting block two that is slidably connected to the connecting cylinder, the bottom of the connecting cylinder is fixedly connected to the top of the connecting column, and a worm gear is fixedly passed through the outer wall of the connecting column.

[0016] By adopting the above technical solution, the outer diameter of the fixed plate is consistent with the inner diameter of the connecting cylinder, thereby limiting the fixed plate through the connecting cylinder, so that the fixed plate can only move vertically.

[0017] Preferably, a limiting cylinder two is movably passed through the outer wall of the connecting column and fixedly connected to the bottom of the inner wall of the lower end housing; a worm wheel is meshed with the outer wall of the worm; a fixed shaft is movably passed through the side wall of the worm wheel; a toothed pulley one is movably passed through the outer wall of the fixed shaft and fixedly connected to the worm wheel; and a toothed pulley two is fixedly passed through the outer wall of the rotating shaft.

[0018] By adopting the above technical solution, the connecting column is limited by the second limiting cylinder, so that the connecting column can only move vertically and rotate axially. Through the transmission of the first toothed pulley, the worm is positioned far from the bottom of the inner wall of the lower housing, thereby avoiding damage to the mounting rail caused by vertical movement.

[0019] Preferably, a toothed belt is sleeved between the second toothed pulley and the first toothed pulley, a fixed plate is fixedly connected to the outer wall of the vertical plate, a rotating plate is fixedly connected to the outer wall of the rotating shaft, and the bottom of the rotating plate is in contact with the fixed plate.

[0020] By adopting the above technical solution, the rotating plate is located on the horizontal axis of symmetry of the rotating shaft, so that the rotating plate can only rotate within a range of 180° due to the limitation of the two fixed plates.

[0021] Preferably, the upper housing sidewall is fixedly connected to a fixing frame that is fixedly connected to the top of the device base plate, and the sidewall of the fixing frame is fixedly connected to the lower housing.

[0022] By adopting the above technical solution, the fixing frame is located on both sides of the upper and lower shells, so that the upper and lower shells are always in a horizontal state.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The cylinder drives the connecting plate to move vertically, which in turn drives the second detection component to move vertically downward, so as to insert it into the hole at the top of the mounting rail, thereby determining whether the hole diameter of the mounting rail is compatible with the hole diameter of the support frame, and thus detecting the hole diameter of the mounting rail;

[0025] 2. The rotating column drives the connecting cylinder to rotate, which in turn drives the connecting column to rotate, thereby rotating the rotating shaft through the worm gear. This allows for the switching between detection component one and detection component two. Therefore, when testing installation rails with different apertures, there is no need to disassemble or replace the device. Simply pre-install the detection components for the different installation rails to be tested on both sides of the connecting block one. This simplifies the work process and improves the device's ability to test different installation rail apertures by switching only some parts. Compared to a single press-type aperture detection component, this device does not require custom-made devices for different aperture installation rails, nor does it require disassembly and reassembly of the entire device for changing apertures. Switching is completed simply by switching between detection component one and detection component two, resulting in a wider range of applications and more convenient operation.

[0040] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0041] This application discloses a device for detecting the aperture of an installation rail.

[0042] Reference Figures 1-3 A mounting rail aperture detection device includes a base plate 1, the top of which is fixedly connected to the bottom of a support component 11. The support component 11 includes rollers, bearings, support plates, etc., for supporting a horizontally moving mounting rail 12. The mounting rail 12 is placed on top of the support component 11. A switching mechanism 2 is provided on the top of the base plate 1. The switching mechanism 2 also includes a sliding block 23 fixedly connected to the bottom output shaft end of a cylinder 22. A support frame 21 is fixedly connected to the top of the base plate 1 at its bottom and is symmetrically distributed on both sides of the cylinder 22. The cylinder 22 is connected to an external... Connected to the control equipment, the cylinder 22 drives the sliding block 23 to intermittently reciprocate vertically through the pre-written control program, and matches the horizontal movement speed of the mounting rail 12, so that the detection component 218 can accurately detect each hole at the top of the mounting rail 12. The support frame 21 adopts a portal frame structure to avoid interference with the movement of the mounting rail 12. The outer wall of the cylinder 22 is fixedly connected to the sleeve by bolts, and the outer wall of the sleeve is fixedly connected to the support frame 21, so that the cylinder 22 is fixedly connected to the support frame 21, thereby fixing the cylinder 22.

[0043] The staff places the mounting rail 12 on top of the support component 11, and then the mounting rail 12 is horizontally transported on top of the support component 11 by a stepping conveyor. Then, when the mounting rail 12 moves through the fixed frame 238 and into the lower housing 29 with the conveyor, the detection component 218 will correspond to the mounting rail 12. At this time, the cylinder 22 drives the sliding block 23 to move vertically downward according to the pre-set control program.

[0044] Reference Figures 2-3 The bottom of the sliding block 23 is fixedly connected to the top of the drive column 24. The center of the drive column 24 and the center of the sliding block 23 are on the same vertical axis. The outer wall of the drive column 24 fits against the inner wall of the fixing ring 25, thus allowing the drive column 24 and the fixing ring 25 to slide together. The outer diameter of the fixing ring 25 is the same as the diameter of the sliding block 23. The bottom of the spring 26 is fixedly connected to the top of the fixing ring 25, and the top of the spring 26 is fixedly connected to the bottom of the sliding block 23. The spring 26 maintains a 1-2 mm gap with the outer wall of the drive column 24 and a 1-2 mm gap with the inner wall of the limiting cylinder 27, thereby preventing damage to the drive column 24 during the extension and retraction of the spring 26. The outer wall and the inner wall of the limiting cylinder 27 are worn. The outer wall of the fixing ring 25 is fixedly connected to the inner wall of the limiting cylinder 27. The outer wall of the sliding block 23 is in contact with the inner wall of the limiting cylinder 27, so that the sliding block 23 is slidably connected to the limiting cylinder 27. The top of the limiting cylinder 27 is fixedly connected to the inner wall of the upper housing 28. A circular hole is opened through the top of the upper housing 28. The sliding block 23 is slidably connected to the circular hole, so that the sliding block 23 is slidably connected to the upper housing 28. The diameter of the inner wall of the limiting cylinder 27 is consistent with the circular hole. The bottom of the upper housing 28 is fixedly connected to the top of the lower housing 29. The inner wall of the upper housing 28 is flush with the inner wall of the lower housing 29.

[0045] The sliding block 23 will drive the drive column 24 to move vertically downwards. The sliding block 23 will slide along the inner wall of the limiting cylinder 27. The sliding block 23 will compress the spring 26. The drive column 24 will slide on the inner wall of the fixed ring 25.

[0046] Reference Figures 2-3The lower housing 29 has a through hole on its side wall that matches the cross-sectional dimensions of the mounting rail 12. The connecting plate 210 is fixedly connected to the bottom of the drive column 24. The geometric center of the top of the connecting plate 210 coincides with the center of the bottom of the drive column 24. The vertical plates 211 are symmetrically fixedly connected to both ends of the connecting plate 210. The outer wall of the vertical plate 211, which is fixedly connected to one end of the connecting plate 210, is fixedly connected to the limiting plate 212. The limiting plate 212 is located in the middle of the side wall of the vertical plate 211 and remains vertical. Both outer walls of the vertical plate 211 are in contact with the clamping plate 213. The upper half of the clamping plate 213, which is close to the inner wall of the upper housing 28, is fixedly connected to the upper housing 28. The lower half is fixedly connected to the inner wall of the lower end housing 29. A second round hole is opened on the side wall of the vertical plate 211. The rotating shaft 214 movably passes through the vertical plate 211 and is rotatably connected to the vertical plate 211. A third round hole is opened through the side wall of the connecting block 1 215. The rotating shaft 214 is fixedly passed through the third round hole, so that the rotating shaft 214 is fixedly connected to the connecting block 1 215. The connecting block 216 is fixed to the upper and lower ends of the connecting block 1 215 respectively. The detection component 1 217 and the detection component 218 are fixed to the upper and lower ends of the connecting block 2 216 respectively. The detection component 1 217 is adapted to the hole diameter standard of one type of mounting rail 12, and the detection component 218 is adapted to the hole diameter standard of another type of mounting rail 12.

[0047] The drive column 24 will drive the connecting plate 210 to move vertically downwards, the connecting plate 210 will drive the vertical plate 211 to move vertically downwards, the vertical plate 211 will drive the connecting block 1 215 to move vertically, the connecting block 1 215 will drive the connecting block 216 to move vertically, the connecting block 216 will drive the detection component 218 to move vertically downwards, and the vertical plate 211 will also drive the fixed shaft 232 to move vertically downwards.

[0048] Reference Figures 3-5The upper housing 28 has a through-hole four at its top, through which the rotating column 220 movably passes, allowing it to be rotatably connected to the upper housing 28. The top of the rotating column 220 is fixedly connected to the bottom of the knob 219, and the bottom of the knob 219 fits against the top of the upper housing 28. The top of the sealing cover 221 has a through-hole five, through which the rotating column 220 movably passes, allowing it to be slidably connected to the sealing cover 221. The top of the sliding plate 222 has a through-hole six, through which the outer wall of the rotating column 220 movably passes, allowing it to be slidably connected to the sliding plate 222. Limiting block 1 2 23 are symmetrically distributed on the outer wall of the sliding disk 222 and fixedly connected to the outer wall of the sliding disk 222. The inner wall of the connecting cylinder 224 has a non-through sliding groove vertically opened. The limiting block 223 is slidably connected to the sliding groove. The bottom of the sliding disk 222 is fixedly connected to the top of the second spring 225. The bottom of the second spring 225 is fixedly connected to the top of the fixed disk 226. When the connecting cylinder 224 moves vertically downward, it drives the sliding disk 222 to move vertically, thereby compressing the second spring 225. When the connecting cylinder 224 moves upward until the bottom of the fixed disk 226 is in contact with the connecting cylinder 224, the second spring 225 drives the sliding disk 222 to reset.

[0049] Fixed shaft 232 drives worm gear 231 to move vertically, worm gear 231 drives worm 229 to move vertically downwards, worm 229 drives connecting column 228 to slide on the inner wall of limiting cylinder 230, connecting column 228 drives connecting cylinder 224 to move vertically, connecting cylinder 224 drives sliding disk 222 to move vertically downwards, sliding disk 222 compresses spring 225, limiting block 227 slides on the inner wall of connecting cylinder 224, detection component 218 and the top hole of mounting rail 12 should be in a fully fitted state, so that detection component 218 and the top of mounting rail 12 are inserted, and the fit between detection component 218 and the top hole of mounting rail 12 is used to detect whether the hole diameter meets the specifications. If the hole diameter is too small, detection component 218 will not be able to detect it. The method is adapted to the top hole diameter of the mounting rail 12, so it cannot be inserted into the top hole of the mounting rail 12. When the cylinder 22 extends, it will be blocked. A pressure sensor (not shown in the figure) is installed in the air circuit of the cylinder 22. When the cylinder extension is blocked, the pressure in the cylinder cavity increases. After the pressure sensor senses that the internal pressure is too high and exceeds the threshold, the pressure sensor will transmit the signal to the control module through the signal line, thereby informing the operator that there is a non-standard hole diameter. After the detection is completed, the detection component 218 rises vertically. The conveying device aligns the next hole on the top of the mounting rail 12 with the detection component 218, thereby realizing the detection of the hole diameter of the entire mounting rail 12. By switching the detection component, the device is suitable for detecting two hole diameter specifications in the range of 3mm to 10mm.

[0050] Reference Figures 5-8The top of the fixed disk 226 is fixedly connected to the bottom of the rotating column 220. The outer wall of the fixed disk 226 is in contact with the inner wall of the connecting cylinder 224. The fixed disk 226 and the connecting cylinder 224 are slidably connected. The outer wall of the fixed disk 226 is fixedly connected to the second limiting block 227. The second limiting block 227 is slidably connected to the sliding groove, thereby making the second limiting block 227 and the connecting cylinder 224 slidably connected. The bottom of the connecting cylinder 224 is fixedly connected to the top of the connecting column 228. The center of the connecting cylinder 224 is connected to the rod of the connecting column 228. The axes coincide, and a circular hole seven is opened through the top of the worm 229. The outer wall of the connecting post 228 is fixedly connected to the circular hole seven, so that the connecting post 228 and the worm 229 are fixedly connected. The outer wall of the connecting post 228 is in contact with the inner wall of the limiting cylinder 230. The bottom of the limiting cylinder 230 is fixedly connected to the inner wall of the lower end housing 29. The limiting cylinder 230 is kept in a vertical state. The teeth on the outer wall of the worm 229 mesh with the teeth on the outer wall of the worm wheel 231, so that the worm wheel 231 rotates when the worm 229 rotates.

[0051] When it is necessary to inspect the mounting rail 12 with a different aperture, the initial state is that the second inspection component 218 is in the working position and the first inspection component 217 is in the standby position. Before rotating the knob 219, the cylinder 22 rises to the initial position to avoid interference. The operator rotates the knob 219, which drives the rotating column 220 to rotate. The rotating column 220 drives the fixed plate 226 to rotate. The fixed plate 226 drives the second limit block 227 to rotate. The second limit block 227 drives the connecting cylinder 224 to rotate. The connecting cylinder 224 drives the connecting column 228 to rotate. The connecting column 228 drives the worm gear 229 to rotate. The worm gear 229 drives the worm wheel 231 to rotate.

[0052] Reference Figures 5-9 The fixed shaft 232 is rotatably connected to the side wall of the worm gear 231. The outer wall of the fixed shaft 232 is rotatably connected to the side wall of the first toothed pulley 233. The side of the first toothed pulley 233 closest to the worm gear 231 is fixedly connected to the worm gear 231. The outer wall of the rotating shaft 214 is fixedly connected to the side wall of the second toothed pulley 234, so that the second toothed pulley 234 and the rotating shaft 214 rotate synchronously. The toothed belt 235 is sleeved between the second toothed pulley 234 and the first toothed pulley 233. The second toothed pulley 234 and the first toothed pulley 233 have the same size. The fixed plate 236 is fixedly connected to the outer wall of the vertical plate 211. The fixed plate 236 is located at... On both sides of the rotating shaft 214, the rotating plate 237 is fixedly connected to the outer wall of the rotating shaft 214. The fixed plate 236 is located in the rotation trajectory of the rotating plate 237. When the rotating plate 237 rotates 180°, it will be limited by the fixed plate 236 on the other side. The side wall of the fixed frame 238 is opened through a second through hole with the same size as the side wall of the lower housing 29. The side wall of the fixed frame 238 is fixedly connected to the upper housing 28 and the lower housing 29, thereby providing stable support for the upper housing 28 and the lower housing 29. The first through hole is aligned with the second through hole. The bottom of the fixed frame 238 is fixedly connected to the top of the device base plate 1.

[0053] The worm gear 231 drives the toothed pulley 233 to rotate. The toothed pulley 233 drives the toothed pulley 234 to rotate via the toothed belt 235. The toothed pulley 234 drives the rotating shaft 214 to rotate. The rotating shaft 214 will rotate 180°, thereby swapping the detection component 217 and the detection component 218. The rotating plate 237 will rotate from the top of one side of the fixed plate 236 to the top of the other side of the fixed plate 236. When the knob 219 is limited by the fixed plate 236 and cannot rotate, the operator knows that the adjustment has been completed, thus completing the switching of different aperture detection functions. The switching does not affect the vertical movement. Only the knob 219 needs to be rotated. The operation is convenient and easy for personnel to understand. There is no need to open the lower housing 29 for replacement.

[0054] The implementation principle of the mounting rail aperture detection device in this application embodiment is as follows:

[0055] The operator places the mounting rail 12 on top of the support component 11. Then, a stepping conveyor transports the mounting rail 12 horizontally across the top of the support component 11. As the mounting rail 12 moves through the fixed frame 238 and into the lower housing 29, the detection component 218 aligns with the mounting rail 12. At this point, the cylinder 22, according to a pre-set control program, drives the sliding block 23 to move vertically downwards. The sliding block 23 then drives the detection component 218 to move vertically downwards. The limiting block 227 slides on the inner wall of the connecting cylinder 224. The detection component 218 and the top aperture of the mounting rail 12 should be in a fully fitted state, allowing the detection component 218 to be inserted into the top of the mounting rail 12. This allows the detection component 218 to detect the top aperture of the mounting rail 12. After the test is completed, the second detection component 218 rises vertically. The conveying device aligns the next hole on the top of the mounting rail 12 with the second detection component 218, thereby enabling the detection of the hole diameter of the entire mounting rail 12. When it is necessary to detect the mounting rail 12 with a different hole diameter, the operator rotates the knob 219. The knob 219 will drive the toothed pulley 234 to rotate, which in turn drives the rotating shaft 214 to rotate. The rotating shaft 214 will rotate 180°, thereby swapping the first detection component 217 and the second detection component 218. The rotating plate 237 will rotate from the top of one side of the fixed plate 236 to the top of the other side of the fixed plate 236. When the knob 219 is limited by the fixed plate 236 and cannot rotate, the operator knows that the adjustment has been completed, thus completing the switching of different hole diameter detection functions.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
