Description

Technical Field

[0001] This invention belongs to the field of guide rail defect detection technology, and in particular relates to a fully automatic guide rail defect detection device. Background Technology

[0002] Existing guide rail fatigue wear testing typically requires controlling a slider to slide back and forth on the guide rail, stopping the machine after a set number of slides, and then manually measuring the wear using testing tools.

[0003] To simulate real-world working conditions, a constant load is typically placed on the slider. However, adjusting this load relies on counterweights of different specifications, which is cumbersome and difficult to dynamically change. Furthermore, in actual working conditions, the slider often experiences eccentric loading, and existing detection methods struggle to simulate and detect fatigue wear under eccentric loads, resulting in operational limitations. Additionally, this method can only acquire wear data after a few discrete points, failing to reflect the continuous wear evolution of the guide rail throughout the entire sliding cycle, leading to limited and incomplete data.

[0004] Therefore, there is an urgent need for a fully automated guide rail defect detection device that can flexibly adjust the load pressure and simulate off-center load conditions, and can continuously detect the wear state of the guide rail at different sliding stages online, thereby obtaining more comprehensive and realistic fatigue wear data and improving detection efficiency and accuracy. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a fully automated guide rail defect detection device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this application provides the following technical solution: The present invention provides a fully automatic guide rail defect detection device, including a base, a guide rail fixing platform, a sliding guide frame, a pressurizing mechanism, a synchronous drive mechanism, and a detection mechanism. The guide rail fixing platform is fixedly disposed on the front side of the base, and multiple sets of guide rail assemblies to be detected are fixedly disposed on the guide rail fixing platform. The sliding guide frame is disposed on the base. The pressurizing mechanism includes a crossbeam plate slidably connected to the sliding guide frame. A first cylinder is fixedly disposed on the crossbeam plate, and a pressure plate is fixedly connected to the telescopic end of the first cylinder. Three pressure sensors are evenly distributed on the lower side of the pressure plate, and each pressure sensor is equipped with a pressure rod group composed of multiple pressure rods, with each pressure rod being detachable. The synchronous drive mechanism is disposed on the base and is connected to the crossbeam plate and the slider in the guide rail assembly to be detected. The detection mechanism includes a sliding assembly disposed on the front side of the base. An L-shaped bracket is disposed on the sliding assembly. A detection fixing part is fixedly disposed on the vertical section of the L-shaped bracket, and a detection moving part is connected to the horizontal section of the L-shaped bracket via a magnetic placement assembly. Each pressure rod assembly is arranged in different numbers and positions below the pressure sensor, so that the pressure rod assembly can apply pressure at different positions to the slider on the guide rail to be tested. The first cylinder extends to drive the pressure rod assembly to contact the corresponding slider, and the pressure is monitored by the pressure sensor. The slider and the pressure rod assembly remain relatively stationary and move back and forth together through the synchronous drive mechanism. The magnetic suction and dropping assembly can periodically lower the detection moving part to the upper surface of the slider on the guide rail to be tested for wear detection.

[0007] According to an advantageous embodiment, the guide rail fixing platform has multiple sets of fixing holes evenly distributed from left to right. Each set of fixing holes is evenly distributed from front to back, and the distance between adjacent fixing holes is the same as the distance between adjacent mounting holes on the guide rail in the guide rail assembly to be tested.

[0008] According to an advantageous embodiment, the sliding guide frame is provided in two sets and is symmetrically distributed from left to right. The sliding guide frame includes two columns fixedly mounted on the base and symmetrically distributed front to back. The upper ends of the two corresponding columns are fixedly connected to the same U-shaped guide rail seat. One end of the crossbeam plate is fixedly connected to a guide seat with a pulley. The guide seat is rolledly connected to the inner wall of the groove on the U-shaped guide rail seat through the pulley.

[0009] According to an advantageous embodiment, a connecting plate is fixedly connected to the lower side of the pressure sensor, and a plurality of connecting seats arranged in a matrix are fixedly disposed on the lower side of the connecting plate. The connecting seats are threadedly connected to the upper end of the pressure rod in the pressure rod assembly. Two guide rods symmetrically arranged on the upper side of the pressure plate are fixedly disposed on the left and right, and the upper end of the guide rod is slidably inserted into the crossbeam plate.

[0010] According to an advantageous embodiment, the synchronous drive mechanism includes three reciprocating drive components mounted on a base via a U-shaped bracket. Each reciprocating drive component has two transmission rods distributed vertically. The upper transmission rod is hinged to a crossbeam plate, and the lower transmission rod is hinged to a clamping component, which clamps and fixes the slider.

[0011] According to an advantageous embodiment, the reciprocating drive assembly includes an I-shaped turntable rotatably mounted on a U-shaped bracket via a rotating shaft, with one end of each of the two transmission rods hinged to the upper and lower surface edges of the I-shaped turntable, respectively. Adjacent rotating shafts are connected by a pulley set for transmission. A drive motor is fixedly mounted on the U-shaped bracket, and the output shaft of the drive motor is connected to one of the rotating shafts by a gear set for transmission.

[0012] According to an advantageous embodiment, the clamping assembly is configured as a U-shaped clamp, with two locking bolts threaded on one side of the U-shaped clamp.

[0013] According to an advantageous embodiment, the sliding assembly includes a slide rail fixedly disposed on the front side of the base, an electric trolley disposed on the slide rail, and the lower end of the vertical section of the L-shaped bracket fixedly disposed on the electric trolley.

[0014] According to an advantageous embodiment, the magnetic drop assembly includes a second cylinder fixedly mounted on the horizontal section of the L-shaped bracket. An I-shaped plate is fixedly connected to the telescopic end of the second cylinder. A symmetrical magnetic mother plate is fixedly mounted on the lower side of the I-shaped plate. A horizontal plate is fixedly connected to the detection moving part. A magnetic sub-plate is mounted on the upper side of the horizontal plate at a position corresponding to the magnetic mother plate. A positioning protrusion is fixedly mounted at the lower end of the horizontal plate. The positioning protrusion corresponds to the position of the bolt mounting hole on the upper surface of the slider.

[0015] According to an advantageous embodiment, spring positioning posts are fixedly provided at the four lower corners of the I-shaped plate, and positioning sleeves with upward openings are fixedly provided at the four upper corners of the horizontal plate at positions corresponding to the spring positioning posts.

[0016] Compared with the prior art, the fully automatic guide rail defect detection device provided by the present invention has the following beneficial effects: 1. In the present invention, by setting up a detachable and freely combinable pressure rod group, and cooperating with the closed-loop control of the first cylinder and the pressure sensor, it is not only possible to quickly adjust the load pressure and realize dynamic changes, but also to apply uniform or non-uniform off-center load pressure to the slider by different arrangements of the pressure rod group (such as asymmetrical arrangement), thereby truly simulating the fatigue wear process of the guide rail under complex stress under actual working conditions and improving detection efficiency.

[0017] 2. In this invention, the detection mechanism automatically lowers the detection moving part onto the upper surface of the slider according to preset time nodes without stopping the machine or requiring manual intervention during the wear test, and collects the straightness and wear data of the guide rail in real time. Compared with the existing technology, which can only obtain detection results at a few discrete time points, this solution can obtain a continuous evolution curve of the guide rail wear amount with sliding time or sliding number of times, providing richer and more accurate experimental evidence for fatigue wear mechanism research and remaining life prediction.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7This application will be described in further detail.

[0027] Please refer to the following: Figure 1 and Figure 2 An automated guide rail defect detection device includes a base 1. A guide rail fixing platform 2 is fixedly mounted on the front upper part of the base 1. The guide rail fixing platform 2 has multiple sets of fixing holes evenly distributed left and right. Each set of fixing holes is evenly distributed front and back, and the spacing between adjacent fixing holes is the same as the spacing between adjacent mounting holes on the guide rail in the guide rail assembly to be tested. The guide rail body in the guide rail assembly to be tested is fixedly mounted on the guide rail fixing platform 2 through the fixing holes.

[0028] See Figures 1-4 The base 1 is also equipped with a sliding guide frame 3 and a synchronous drive mechanism 5. The sliding guide frame 3 is equipped with a pressurizing mechanism 4, which includes a crossbeam plate 41 slidably connected to the sliding guide frame 3. A first cylinder 42 is fixedly mounted on the crossbeam plate 41, and a pressure plate 43 is fixedly connected to the telescopic end of the first cylinder 42. Three pressure sensors 44 are evenly distributed on the lower side of the pressure plate 43. Each pressure sensor 44 is equipped with a pressure rod group 45 composed of multiple pressure rods 45, and each pressure rod is detachable. The synchronous drive mechanism 5 is connected to the crossbeam plate 41 and the slider 100 in the guide rail assembly to be tested.

[0029] The first cylinder 42 drives each set of pressure rods 45 on the pressure plate 43 to approach the slider 100 in the corresponding guide rail assembly to be tested, so that the pressure rods 45 keep in contact with the upper side of the slider 100 and generate a certain pressure. This pressure is measured by the pressure sensor 44 on each pressure rod set 45 and fed back to the external controller. This pressure can be quickly obtained by direct pressurization of the first cylinder 42 and changed as needed. Finally, the synchronous drive mechanism 5 synchronously drives the pressure rods 45, which are kept under pressure, to reciprocate together with the slider 100.

[0030] In order to apply uniform or non-uniform off-center load pressure to the upper side of different sliders 100, a connecting plate 8 is fixedly connected to the lower side of the pressure sensor 44. Multiple connecting seats 9 are fixedly arranged in a matrix on the lower side of the connecting plate 8. The connecting seats 9 are threadedly connected to the upper end of the pressure rod in the pressure rod group 45. Two guide rods 10 are fixedly arranged on the upper side of the pressure plate 43, and the upper end of the guide rod 10 is slidably inserted into the crossbeam plate 41.

[0031] By disassembling and freely combining the pressure rod group 45 on the lower side of the connecting plate 8, different numbers and arrangements of pressure rod groups 45 are designed to act on the corresponding slider 100, simulating the load situation of the slider 100 in actual use.

[0032] See figure Figure 2 and Figure 4The sliding guide frame 3 has two sets symmetrically distributed on the left and right. Each sliding guide frame 3 includes two uprights 31 fixedly mounted on the base 1 and symmetrically distributed front and back. The upper ends of the two corresponding uprights 31 are jointly and fixedly connected to the same U-shaped guide rail seat 32. One end of the crossbeam plate 41 is fixedly connected to a guide seat 7 with pulleys. The guide seat 7 is rolled along the inner wall of the groove on the U-shaped guide rail seat 32 via pulleys to reduce friction when the crossbeam plate 41 slides. The crossbeam plate 41 is driven to move back and forth along the U-shaped guide rail seat 32 by a synchronous drive mechanism 5.

[0033] See Figures 1-3 To ensure that the pressure rod assembly 45 and the slider 100 can remain relatively stationary and reciprocate together, the synchronous drive mechanism 5 includes three reciprocating drive components 51 mounted on the base 1 via a U-shaped bracket. Each reciprocating drive component 51 has two transmission rods 52 distributed vertically. The upper transmission rod 52 is hinged to the crossbeam plate 41, and the lower transmission rod 52 is hinged to a clamping component 53, which clamps and fixes the slider 100.

[0034] The reciprocating drive assembly 51 includes an I-shaped turntable 511 rotatably mounted on a U-shaped bracket via a rotating shaft. One end of each of the two transmission rods 52 is hinged to the upper and lower surface edges of the I-shaped turntable 511, respectively. Adjacent rotating shafts are connected by a pulley set 512. A drive motor 513 is fixedly mounted on the U-shaped bracket. The output shaft of the drive motor 513 is connected to one of the rotating shafts by a gear set 514.

[0035] The drive motor 513 and gear set 514 cause the I-shaped disk to rotate. The adjacent I-shaped disks are driven by the pulley set 512 to achieve simultaneous rotation of the three I-shaped disks. The rotation of the I-shaped disks causes the upper and lower transmission rods 52 to push and pull the crossbeam plate 41 and the slider 100 back and forth.

[0036] See Figure 3 The clamping assembly 53 is configured as a U-shaped clamp, with two locking bolts threaded on one side. The U-shaped clamp is used to clamp the slider 100 onto its surface, enabling quick clamping of the slider 100.

[0037] See Figures 1-7 A detection mechanism 6 is fixedly installed on the front side of the base 1. The detection mechanism 6 includes a sliding component 61 installed on the front side of the base 1. An L-shaped bracket 62 is installed on the sliding component 61. A detection fixing part 63 (laser emitter) is fixedly installed on the vertical section of the L-shaped bracket 62. A detection moving part 65 (detection target) is connected to the horizontal section of the L-shaped bracket 62 through a magnetic drop component 64.

[0038] Under normal conditions, the testing mechanism 6 moves to the blank area between two adjacent guide rail assemblies to be tested, so as to avoid interfering with the reciprocating motion of the pressure rod assembly 45.

[0039] When it is necessary to perform multi-time node sampling and detection on one of the guide rail assemblies, the slider 100 moves to a position close to the front, and then the pressure rod assembly 45 moves upward to reset. The L-shaped bracket 62 moves the detection moving part 65 directly above the slider 100 under the movement of the sliding assembly 61, and then the detection moving part 65 is lowered onto the slider 100 by the magnetic attraction and placement assembly 64.

[0040] Then, the slider 100, carrying the detection moving part 65, slowly moves along the guide rail while the detection fixing part 63 remains stationary, to detect the straightness of the guide rail. After detection, it is reset, and the moving part is picked up and moved away again by the magnetic attraction and release assembly 64. Then, the guide rail and slider 100 continue to repeat the pressure and sliding action, and the detection is repeated until the predetermined detection time or number of sliding times is reached.

[0041] Compared with existing technologies that only perform a single inspection after the test, this solution can automatically detect the wear data of the guide rail and slider 100 over a period of time, and obtain continuous evolution data of the wear amount of the guide rail with sliding time (or sliding times), providing richer and more accurate experimental evidence for studying fatigue wear mechanism and predicting the remaining life of the guide rail.

[0042] See Figure 1 and Figure 5 The sliding component 61 includes a slide rail fixedly mounted on the front side of the base 1, an electric trolley mounted on the slide rail, and the lower end of the vertical section of the L-shaped bracket 62 fixedly mounted on the electric trolley. The electric trolley can be an electric slide module, that is, an integrated module in which a ball screw or synchronous belt driven by a servo motor or stepper motor drives the slide block to reciprocate along the slide rail.

[0043] See Figures 5-7 To facilitate the smooth and accurate placement of the detection moving part 65 onto the slider 100, the magnetic placement assembly 64 includes a second cylinder 641 fixedly mounted on the horizontal section of the L-shaped bracket 62. An I-shaped plate 642 is fixedly connected to the telescopic end of the second cylinder 641. Symmetrical magnetic mother plates 643 are fixedly mounted on the lower side of the I-shaped plate 642. A horizontal plate 644 is fixedly connected to the detection moving part 65. A magnetic daughter plate 645 is positioned on the upper side of the horizontal plate 644 corresponding to the position of the magnetic mother plate 643. A positioning protrusion 646 is fixedly mounted at the lower end of the horizontal plate 644, corresponding to the bolt mounting holes on the upper surface of the slider 100. The magnetic mother plate 643 is an electromagnetic suction plate, and the magnetic daughter plate 645 is an iron plate.

[0044] When the detection moving part 65 and the horizontal plate 644 move to directly above the slider 100 to be tested under the drive of the electric trolley, the control system activates the second cylinder 641, driving the horizontal plate 644 to move downwards at a slow and steady speed. The positioning protrusion 646 on the lower side of the horizontal plate 644 then gradually inserts into the port of the pre-drilled bolt mounting hole on the upper surface of the slider 100. Through the minute gap between the hole and the positioning protrusion 646, precise alignment and positioning of the horizontal plate 644 and the detection moving part 65 are achieved. After positioning, the detection moving part 65 maintains contact with the upper surface of the slider 100 and slides back and forth with the slider 100 to collect wear data in real time during the movement.

[0045] After a single test is completed, the slider 100 returns to its original position. The second cylinder 641 drives the magnetic mother plate 643 to move down and contact the magnetic sub-plate 645 on the upper side of the horizontal plate 644. When the magnetic mother plate 643 is energized, an adsorption force is generated. When the second cylinder 641 retracts, the horizontal plate 644 and the detection moving part 65 are pulled up from the slider 100 and then reset to their original positions by the electric trolley. After the horizontal plate 644 is misaligned with the slider 100, the second cylinder 641 lowers the horizontal plate 644 to the guide rail fixing platform 2. At the same time, the magnetic mother plate 643 is de-energized, so that the horizontal plate 644 is separated from the magnetic mother plate 643, thus preventing the magnetic mother plate 643 and the magnetic sub-plate 645 from being in an energized adsorption state for a long time.

[0046] It should be noted that although the slider 100 will experience some surface wear during long-term fatigue wear tests, especially in the raceway area where the wear may reach the micrometer or even tens of micrometer levels, this will not substantially affect the positioning accuracy of the aforementioned positioning mechanism. This is because the reference surface into which the positioning protrusion 646 is inserted is the bolt mounting hole port on the upper surface of the slider 100. The positional accuracy of this mounting hole is independently guaranteed during the manufacturing process of the slider 100, and its relative dimensions to the bottom surface of the slider 100 are minimally affected by raceway wear. Even if the overall height of the slider 100 decreases slightly due to raceway wear, the outline and center position of the bolt mounting hole can still maintain their original positional accuracy. Therefore, the positioning protrusion 646 on the lower side of the horizontal plate 644 can still reliably and repeatedly insert into this hole, achieving high-precision positioning and ensuring that the detection moving part 65 is accurately positioned each time it is lowered.

[0047] See Figure 6Spring positioning posts 647 are fixedly installed at the four lower corners of the I-shaped plate 642, and opening-up positioning sleeves 648 are fixedly installed at the four upper corners of the horizontal plate 644 at positions corresponding to the spring positioning posts 647. To ensure precise alignment between the magnetic female plate 643 and the magnetic female plate 645, when the magnetic female plate 643 moves downward, the lower end of the spring positioning post 647 first inserts into the corresponding positioning sleeve 648. Then, as the spring positioning post 647 is compressed, the magnetic female plate 643 continues to move downward until the magnetic female plate 643 and the magnetic female plate 645 are precisely aligned.

[0048] This invention addresses the shortcomings of existing guide rail fatigue wear testing methods, such as load adjustment relying on counterweights, inability to simulate off-center load conditions, discrete test data, and the need for manual measurement with machine shutdown. It provides a fully automated testing device.

[0049] The device, through the freely combinable pressure rod assembly 45 in conjunction with the first cylinder 42 and pressure sensor 44, achieves rapid adjustment and dynamic change of load pressure, and can apply uniform or non-uniform off-center load pressure to the slider 100, realistically simulating the complex stress state in actual use.

[0050] Simultaneously equipped with an automatic detection mechanism 6, the system can automatically complete online detection of guide rail straightness according to preset time nodes without stopping the machine during the wear test, obtaining continuous data on the evolution of wear amount with sliding time (or number of times). Furthermore, using the bolt mounting holes on the upper surface of the slider 100 as a positioning reference, combined with the minute clearance fit of the positioning protrusion 646, ensures the repeatability of the detection moving part 65, and even if significant wear occurs in the raceway, it does not affect the positioning reliability. In summary, this solution improves the automation level, data completeness, and experimental efficiency of guide rail fatigue wear detection, comprehensively overcoming the shortcomings of existing technologies.
