Description

Technical Field

[0001] The present application relates to the technical field of guide rail production and processing, and in particular to a finished product inspection table for guide rail production. Background Art

[0002] The finished product inspection bench of guide rail production is a special equipment used to conduct comprehensive inspection and evaluation of the finished guide rail. This inspection bench is usually equipped with various measuring tools, testing equipment and fixtures to ensure that the performance indicators of the guide rail meet the design requirements and quality standards. During the inspection of the guide rail, it is usually necessary to conduct functional inspections, such as the surface flatness of the guide rail, whether it is bent, and the load-bearing capacity, in order to evaluate its performance in actual applications.

[0003] However, when the existing devices detect the load-bearing capacity, they generally use hydraulic cylinders to assist in applying pressure to the guide rails. The pressure applied causes the guide rails to deform and bend. At this time, the pressure is detected with the assistance of a pressure sensor to measure the pressure data. During use, the existing devices generally have a clamping structure that clamps the guide rails and the guide rails are in a fixed state. Obviously, they are unable to accurately perform pressure tests on different positions of the guide rails. At the same time, during the test, they are unable to detect the surface flatness and whether they are bent. It can be seen that the existing devices have certain defects and deficiencies during use and need to be improved. Utility Model Content

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0029] Example

[0030] refer to Figures 1 to 5 A finished product inspection table for guide rail production of the present embodiment includes: a base 100, support legs 200 are fixedly installed at the four corners of the top of the base 100, an inspection table body 500 is fixedly installed on the top of the support legs 200, positioning drive mechanisms 300 are fixedly installed on both sides of the top of the inspection table body 500, a guide rail body 400 is installed on the top of the inspection table body 500 through the positioning drive mechanism 300, a reserved groove 600 is opened in the middle of the top of the inspection table body 500, a support frame 700 is fixedly installed in the middle of the outer side of the inspection table body 500, a detection mechanism 800 is fixedly installed in the middle of the upper end of the support frame 700, a controller 900 is fixedly installed on the upper end of the front of the support frame 700, and a display screen 1000 is fixedly connected to the front of the controller 900.

[0031] The driving mechanism 300 includes a concave seat 310, which is fixedly installed on both sides of the top of the inspection table body 500. An adjustment component 320 is fixedly installed on the inner side of the concave seat 310. A driving component 330 is fixedly installed on both sides of the top of the adjustment component 320. The guide rail body 400 is arranged on the inner side of the driving component 330.

[0032] The detection mechanism 800 includes a hydraulic cylinder 810, which is fixedly installed in the middle of the top of the support frame 700. The bottom output end of the hydraulic cylinder 810 passes through the support frame 700 and is fixedly installed with a pressure sensor 820. Telescopic springs 830 are fixedly installed at equal intervals at the bottom of the pressure sensor 820. A mounting seat 840 is fixedly installed at the bottom of the telescopic spring 830. A pressure roller 850 is rotatably connected inside the mounting seat 840. The base 100 serves as the foundation of the entire inspection table body 500. The inspection table body 500 is supported by the support legs 200. Positioning drive mechanisms 300 are installed on both sides of the top of the inspection table body 500 for accurately positioning and driving the guide rail body 400. A slot is reserved in the center of the top of the inspection table body 500 to facilitate various detection operations.

[0033] The support frame 700 is installed in the middle of the outer side of the inspection table body 500, providing a stable support for the detection mechanism 800. The core components of the detection mechanism 800 include a hydraulic cylinder 810, a pressure sensor 820, a telescopic spring 830, a mounting seat 840 and a pressure roller 850. The hydraulic cylinder 810 is fixed by the support frame 700, and its bottom output end is connected to the pressure sensor 820. A series of telescopic springs 830 are installed at the bottom of the pressure sensor 820, which can be extended and retracted according to the pressure received. The mounting seat 840 is fixed to the bottom of the telescopic spring 830, and a rotatable pressure roller 850 is installed inside, which is used to contact with the guide rail body 400 during the detection process to simulate the pressure situation in actual use. The controller 900 and the display screen 1000 are installed at the upper front end of the support frame 700, which is convenient for the operator to observe and control the entire detection process. Through the controller 900, the operator can accurately control the actions of the driving mechanism 300 and the detection mechanism 800 to ensure the accuracy and reliability of the detection results.

[0034] The adjustment assembly 320 includes a first motor 321 and a slide 322. The slide 322 is provided in the middle of the concave seat 310. The first motor 321 is fixedly installed in the middle of one side of the concave seat 310. The output end of the first motor 321 passes through the concave seat 310 and is fixedly installed with a screw rod 323. The screw rod 323 is rotatably connected to the inside of the slide 322. The two ends of the screw rod 323 have opposite thread rotation directions. Both ends of the screw rod 323 are threadedly connected with a sliding block 324. The sliding block 324 is slidably connected to the inside of the slide 322. The top of the sliding block 324 is fixedly connected to the bottom of the driving assembly 330. The first motor 321 is fixedly installed in the middle of one side of the concave seat 310. The output end thereof passes through the concave seat 310 and is connected to the screw rod 323. The screw rod 323 is driven to rotate inside the slide 322. The two ends of the screw rod 323 have opposite thread rotation directions. When the screw rod 323 rotates, the sliding blocks 324 at both ends will move simultaneously but in opposite directions along the slide groove 322. The top of the sliding block 324 is fixedly connected to the bottom of the driving component 330. Therefore, the movement of the sliding block 324 will drive the driving component 330 to move accordingly, thereby achieving auxiliary clamping and positioning of the guide rail body 400.

[0035] The overall cross-sectional shape of the sliding block 324 is set to be a convex shape, and the internal cross-sectional shape of the chute 322 is also set to be a convex shape. The outer surface of the sliding block 324 and the inner wall of the chute 322 are both fixedly connected with wear-resistant pads. The overall cross-sectional shape of the sliding block 324 is set to be a convex shape, and the internal cross-sectional shape of the chute 322 is also correspondingly designed to be a convex shape. This shape design not only increases the contact area between the sliding block 324 and the chute 322, improves the sliding stability, but also can effectively prevent the sliding block 324 from shaking or deflecting during the sliding process. More importantly, the outer surface of the sliding block 324 and the inner wall of the chute 322 are both fixedly connected with wear-resistant pads. The application of wear-resistant pads plays a key role here. Since the sliding block 324 slides back and forth inside the chute 322, long-term work may cause wear on the contact surface of the sliding block 324 and the chute 322, thereby affecting the accuracy and stability of the adjustment component 320. The addition of wear-resistant pads can significantly reduce such wear and improve the service life of the adjustment component 320.

[0036] The driving assembly 330 includes a top seat 331, which is T-shaped when viewed from above and is fixedly mounted on the top of the sliding block 324. The top outer end of the top seat 331 is arranged in an isosceles triangle shape and is rotatably connected to a transmission pulley 332, which is connected to each other through a transmission belt. A second motor 333 is fixedly mounted on the bottom outer end of the top seat 331, and the output end of the second motor 333 passes through the top seat 331 and is fixedly connected to the bottom of the transmission pulley 332.

[0037] A groove 334 is provided on the inner side of the top seat 331, and guide rollers 335 are rotatably connected to the inner side of the groove 334 at equal intervals. The top of the top seat 331 is fixedly connected to the bottom of the transmission pulleys 332 at both ends and the top of the guide rollers 335 at both ends. The top seat 331 serves as the basic structure of the driving component 330, and its top view shape is T-shaped, which provides a stable installation platform for the transmission pulleys 332 and the guide rollers 335. The top seat 331 is fixedly installed on the top of the sliding block 324. As the sliding block 324 moves, the top seat 331 and the components thereon can also adjust their positions accordingly.

[0038] At the top outer end of the top seat 331, the transmission pulleys 332 are arranged in an isosceles triangle shape and rotatably connected. This layout ensures the smooth operation of the transmission belt and improves the transmission efficiency. The transmission pulleys 332 are connected by the transmission belt to form a continuous transmission system, which provides power for the transmission of the guide rail body 400.

[0039] The second motor 333 is located at the bottom outer end of the top seat 331, and serves as the power source of the driving assembly 330. Its output end passes through the top seat 331 and is fixedly connected to the bottom of the transmission pulley 332. When the second motor 333 is started, it can directly drive the transmission pulley 332 to rotate, thereby driving the entire transmission system to work. The inner side of the groove 334 is rotatably connected with guide rollers 335 at equal intervals. The function of these guide rollers 335 is to support and transmit the guide rail body 400 to ensure its stability and stability during the transmission process. The top of the guide roller 335 is fixedly connected to the bottom of the transmission pulley 332 at both ends, forming a complete transmission path. When the transmission pulley 332 rotates, the guide roller 335 is driven to rotate synchronously through the transmission belt, thereby realizing stable transmission of the guide rail body 400.

[0040] A receiving plate 336 is fixedly installed on the inner lower end of the top seat 331, and balls 337 are rotatably connected to the top of the receiving plate 336 at equal intervals. The addition of balls 337 not only further enhances the stability of the guide rail body 400 during the transmission process, but also reduces the friction between the guide rail body 400 and the guide rail body 400 by rolling, thereby reducing the wear rate and extending the service life of the equipment.

[0041] The top of the base 100 is located in the middle of both sides of the reserved groove 600 and is fixedly installed with a fixed block 1100. The top of the fixed block 1100 is also rotatably connected with balls 337 at equal intervals. By setting the fixed block 1100 and the balls 337 on the top, it can assist in supporting the guide rail body 400 moved to the reserved groove 600, which can improve the stability during detection.

[0042] The top of the test bench body 500 is located on both sides of the reserved groove 600 and is fixedly installed with support rods 860. The top of the support rod 860 passes through the mounting seat 840 and the support frame 700. The top of the support rod 860 is not only fixed to the top structure of the test bench body 500, but also passes through the mounting seat 840 and the support frame 700. The support frame 700 is used to support the mounting seat 840 and ensure its stability during the test. The top of the support rod 860 passes through the mounting seat 840 and the support frame 700, forming a stable three-layer structure, so that the entire test device can remain stable during the test, and the mounting seat 840 can stably move inside the support frame 700 to avoid affecting the accuracy of the test results due to vibration or movement.

[0043] The use principle and advantages are as follows: by setting the driving mechanism 300 to cooperate with the detection mechanism 800, the device can be placed on the top of the receiving plate 336 by placing the guide rail body 400 to be detected during use. At this time, by starting the first motor 321 to run, the first motor 321 is used to drive the screw rod 323 inside the slide 322 to rotate. The screw rod 323 rotates to assist in driving the sliding block 324 to slide back and forth inside the slide 322, and then the sliding block 324 can be assisted in driving the top seat 331 to move relative to each other. The top seat 331 can assist in driving the receiving plate 336 relative to each other by moving relative to each other. At this time, the inner side of the guide roller 335 and the two sides of the guide rail body 400 fit each other, which can assist in adapting and clamping the different sizes of the guide rail bodies 400 to be detected, and can improve the adaptability of the device during the overall detection. In the detection process, the second motor 333 can be started to run, and the second motor 333 can be used to drive the transmission pulley 332 to rotate, and the transmission pulleys 332 are connected by the transmission belt transmission, and the drive can be assisted at this time. In addition, the transmission pulleys 332 at both ends can drive the guide rollers 335 located at both ends to rotate by rotating. The rotation of the guide rollers 335 can assist in driving the guide rail body 400 to slide laterally on the top of the receiving plate 336, so that the device can detect any position of the guide rail body 400 during the detection period, thereby improving the overall detection convenience and accuracy of the device.

[0044] In addition, during the detection process, the hydraulic cylinder 810 is started to drive the pressure sensor 820 and the mounting seat 840 at the bottom to move downward, and the mounting seat 840 drives the pressure roller 850 to contact the guide rail body 400 to be detected. The guide rail body 400 is deformed, and its pressure data can be detected by the pressure sensor 820, which is convenient for detecting the overall compressive load-bearing capacity of the guide rail. During the detection process, the guide roller 335 is driven to move laterally by the operation of the driving component 330. At this time, the hydraulic cylinder 810 is adjusted to push the pressure roller 850 to contact the top of the guide rail body 400. The guide rail body 400 moves laterally at the bottom of the pressure roller 850, and the pressure roller 850 rolls relatively at the top of the guide rail body 400. When the guide rail body 400 is bent or has an uneven surface, the pressure roller 850 will move, causing the telescopic spring 830 to be subjected to pressure changes. At this time, the pressure sensor 820 can be used to assist in detecting the pressure condition. Pressure fluctuations indicate that the guide rail is bent or has an uneven surface, and the amplitude of the pressure fluctuations directly reflects the uneven surface or bending of the guide rail, making the overall detection of the device more convenient and the overall detection adaptability stronger. It can simultaneously detect the load-bearing capacity and the flatness of the curved surface of the guide rail, thereby improving the overall performance of the device.
