Description

Technical Field

[0001] The present application relates to the technical field of guide rail and slider testing, and in particular to a guide rail and slider testing platform. Background Art

[0002] A guide rail and a slider are mechanical components, which usually consist of two parts: a guide rail and a slider. The guide rail is generally fixedly installed on the basic structure of the mechanical equipment and has a specific shape and a high-precision surface. The slider is installed on the movable part and can perform smooth linear motion along the guide rail. The guide rail and slider system has many advantages, such as providing high-precision guidance to ensure the accuracy and stability of movement. It can withstand large loads and adapt to various working environments. In many mechanical equipment, such as CNC machine tools, automated production lines, printing equipment, etc., guide rails and sliders play a vital role in achieving precise position control and efficient motion transmission, thereby improving the working efficiency and processing accuracy of the equipment.

[0003] After the slider is processed, it must be fully tested to accurately evaluate the moving performance of the slider on the guide rail. Specifically, it is necessary to test key indicators such as the resistance of the slider on the guide rail, the parallelism of the slider and the guide rail, and the life of the slider on the guide rail. Usually, when testing the resistance and parallelism of the slider, the tester will first fix the guide rail to the work surface with screws, and then push the slider on the guide rail by hand for testing. However, this method has obvious disadvantages. Since it is a manual operation, the slider movement speed and force uniformity cannot be guaranteed, which can easily lead to inaccurate test data, which in turn seriously affects the test results of the slider guide rail. In the prior art, although there is a specific device that drives the slider to be tested to reciprocate on the linear guide rail through the screw slider mechanism, so as to test the life of the slider to be tested on the linear guide rail, however, this device has many shortcomings during actual application. On the one hand, when installing the linear guide rail, it adopts bolt-assisted installation, which makes it extremely cumbersome and inconvenient to replace the entire linear guide rail during use. On the other hand, the bolt installation method is not convenient for replacing and testing sliders and guide rails of different sizes to be tested in actual use. In summary, this device has certain defects and shortcomings during the overall use process, and it is urgently in need of improvement. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0028] Example

[0030] The positioning mechanism 300 includes a middle slide 310 and a first motor 320. The middle slide 310 is opened in the middle of the top of the top seat 500. The first motor 320 is fixedly installed in the middle of one side of the top seat 500. The interior of the middle slide 310 is rotatably connected to the first screw rod 330. The first screw rod 330 is rotatably connected to the interior of the middle slide 310. The threads at both ends of the first screw rod 330 rotate in opposite directions. Both ends of the first screw rod 330 are threadedly connected to the limiting assembly 340. The limiting assembly 340 is movably connected to both sides of the middle slide 310. The outer side of the limiting assembly 340 is fitted with the two ends of the inner side of the linear guide rail 800. The base plate 100 and the support leg 200 provide a stable support structure for the entire device. To ensure the stability of the device during the test, the middle slide 310 and the first motor 320 in the positioning mechanism 300 cooperate with each other, and the design of the opposite rotation directions of the threads at both ends of the first screw rod 330 is very clever, which can drive the limit components 340 at both ends to move synchronously in the opposite directions in the middle slide 310. The limit components 340 can be fitted and connected with the two ends of the inner side of the linear guide 800, thereby realizing precise positioning and clamping of linear guides 800 of different sizes. This design enables the device to quickly adapt to linear guides 800 of different specifications, improving the convenience and versatility of use. At the same time, the reliability of the positioning mechanism 300 also provides a stable foundation for subsequent testing work, ensuring the accuracy of the test results.

[0031] The limiting assembly 340 includes a sliding block 350, a limiting plate 347 and a side sliding groove 341. The sliding block 350 is slidably connected to the two ends of the middle sliding groove 310. The sliding block 350 and the two ends of the first screw rod 330 are threadedly connected. The top of the sliding block 350 is fixedly installed with a hinge seat 342. The side sliding groove 341 is opened at the four corners of the top of the top seat 500. The side sliding groove 341 and the middle sliding groove 310 are vertically arranged. The inner side of the side sliding groove 341 is slidably connected to the side slider 343. The top of the side slider 343 is rotatably connected to the rotating wheel 344. A linkage rod 345 is fixedly installed on the inner side of the rotating wheel 344, and the inner end of the linkage rod 345 is hinged to the two sides of the hinge seat 342. A clamping plate 346 is fixedly installed on the outer side of the side slider 343. The limit plate 347 is fixedly installed at the four corners of the top of the top seat 500. The linear guide rail 800 is arranged between the limit plate 347 and the inner side of the clamping plate 346. The sliding block 350 is threadedly connected to the first screw rod 330 in the middle slide groove 310, and can slide accurately according to the rotation of the first screw rod 330 to achieve stable position adjustment. The setting of the hinged seat 342 enables the movement of the sliding block 350 to be transmitted to the side slider 343 through the linkage rod 345. The side slide groove 341 provides a clear movement track for the side slider 343, ensuring that the side slider 343 slides stably in the direction perpendicular to the middle slide groove 310. The design of the rotating wheel 344 makes the linkage rod 345 more flexible and smooth when pushing the side slider 343. The clamping plate 346 on the outside of the side slider 343 cooperates with the limit plates 347 at the four corners of the top of the top seat 500 to firmly clamp the linear guide 800 between the two, and can adapt to linear guides 800 of different sizes, thereby improving the versatility of the device. This design enables the linear guide 800 to remain stable during the test, providing a guarantee for accurate test results.

[0032] The adjusting mechanism 600 includes a fixed plate 610, which is fixedly mounted on the top of a support plate 400. A second motor 620 is fixedly connected to the outer side of the fixed plate 610. The output end of the second motor 620 passes through the fixed plate 610 and the support plate 400 and is fixedly mounted with a second screw rod 630. The second screw rod 630 is rotatably connected between the inner sides of the upper ends of the two support plates 400. The outer surface of the second screw rod 630 is threadedly connected to a movable block 640. Both ends of the movable block 640 are fixedly connected to the inner side of the movable mechanism 700. Side plates 660 are fixedly mounted on both sides of the upper end of the support plate 400. A guide shaft 650 is fixedly mounted on the inner side of the side plate 660. The guide shaft 650 passes through the movable block 640, and the movable block 640 is slidably connected to the outer surface of the guide shaft 650. The fixed disk 610 provides a stable installation position for the second motor 620, ensuring that the motor remains stable during operation. The second motor 620 drives the second screw rod 630 to rotate. This transmission method is accurate and reliable and can accurately control the position of the movable block 640. The movable block 640 is threadedly connected to the second screw rod 630, so that the movable block 640 can perform precise linear movement according to the rotation of the screw rod, thereby providing stable power output for the movable mechanism 700. The guide shafts 650 on the two side plates 660 have a good limiting and guiding effect on the movable block 640, ensuring that the movable block 640 remains stable during lateral displacement without offset or shaking. This design improves the accuracy and stability of the device during the adjustment process, and provides reliable power and guide support for the testing of the guide rail slider.

[0033] The movable mechanism 700 includes a vertical rail 710, which is fixedly installed on both sides of the movable block 640. The vertical rail 710 is slidably connected to a slide plate 720 inside the vertical rail 710, and the lower end of the outer side of the slide plate 720 is fixedly connected to a slide frame 730. The slide frame 730 is sleeved and slides on the outer side of the linear guide rail 800. The upper end of the outer side of the slide plate 720 is threadedly connected to a hand-tightened screw 740, and the end of the hand-tightened screw 740 passes through the slide plate 720. Limiting holes 750 are opened at equal intervals on the inner side of the vertical rail 710, and the end of the hand-tightened screw 740 is inserted into the inner side of a limiting hole 750. A test instrument mounting plate 760 is fixedly installed on the outer side of the top of the slide frame 730. Mounting holes are opened at the four corners of the top of the test instrument mounting plate 760, and the mounting holes are set as countersunk holes. The vertical rail 710 provides a stable sliding track for the skateboard 720, ensuring that the skateboard 720 can move up and down smoothly. The sliding frame 730 at the lower end of the outer side of the skateboard 720 can be mounted on the outer side of the linear guide rail 800 and slide to achieve a close fit with the linear guide rail 800, ensuring that the performance of the guide rail slider can be accurately reflected during the test process. The hand-tightened screw 740 is easy and quick to set up, and the skateboard 720 can be fixed at different heights as needed to adapt to linear guide rails 800 of different sizes and different test requirements. The setting of the test instrument mounting plate 760 provides an installation position for the test instrument. The countersunk mounting holes at the four corners of the top make the installation more stable, and also make the surface of the instrument after installation more flat and beautiful. The overall movable mechanism 700 is flexible in design and easy to operate, which can meet the needs of different test scenarios.

[0034] The principle of use and advantages are as follows: the guide rail slider test platform provided by the embodiment of the present application has significant advantages. By carefully setting the positioning mechanism 300, during the use of the device, the linear guide rails 800 can be placed on both sides of the top of the top seat 500. At this time, the first motor 320 is started to run, and the first motor 320 drives the first screw rod 330 to rotate. It is worth noting that the threads at both ends of the first screw rod 330 rotate in opposite directions. This design enables the first screw rod 330 to drive the two sliding blocks 350 to slide on the inner side of the middle slide groove 310. As the sliding block 350 slides synchronously, the hinge seat 342 can be driven to move with each other. After the hinge seat 342 moves with each other, the linkage rod 345 can be driven to move. The end of the linkage plate is connected to the side slider 343 through the rotating wheel 344. When the linkage rod 345 is pushed, the side slider 343 can be adaptively pushed to slide on the inner side of the side slide groove 341. During this period, the rotating wheel 344 will adaptively rotate, thereby prompting the side slider 343 to push the clamping plate 346 outward. After the clamping plate 346 moves outward, the linear guide rail 800 can be squeezed and pressed tightly. At this time, the clamping plate 346 and the limiting plate 347 limit each other, which can assist in clamping and positioning the linear guide rails 800 of different sizes. When the linear guide rail 800 needs to be removed, it is only necessary to start the first motor 320 to drive the two sliding blocks 350 to move outward, and then the side slide block 343 can be pulled out to slide inward on the inner side of the side slide groove 341. In this way, the clamping plate 346 and the limiting plate 347 can be separated from each other, and the linear guide rail 800 between the clamping plate 346 and the inner side of the limiting plate 347 can be easily taken out. It can be seen that the device as a whole is convenient for quickly taking and placing linear guide rails 800 of different sizes, which greatly improves the overall convenience of use of the device.

[0035] At the same time, by arranging the adjustment mechanism 600 and the movable mechanism 700 to cooperate, the device can be used to install the detection instruments and micrometers required for the test on the top of the test instrument mounting plate 760 by bolts during use. When the linear guide rail 800 is installed, the slide frame 730 is sleeved on the outer surface of the linear guide rail 800. At this time, the second motor 620 is started to run, and the second motor 620 can drive the second screw rod 630 to rotate. The rotation of the second screw rod 630 can drive the movable block 640 on its outer surface to slide. Guide shafts 650 are set at both ends of the movable block 640. The sliding of the movable block 640 and the guide shaft 650 can assist in limiting and guiding the movable block 640, so that the movable block 640 can stably move laterally on the guide shaft 650 and the second screw rod 630. At this time, the movement of the movable block 640 can assist To help push the slide frame 730 to slide on the outer surface of the linear guide 800, the second motor 620 is used to drive the second screw rod 630, which can enable the slide frame 730 to move stably on the linear guide 800, greatly improving its uniformity and stability during detection. Moreover, during the detection process, the hand-tightened screw 740 is used to install the slide plate 720, so that when it is necessary to adapt to linear guides 800 of different sizes, it is only necessary to manually twist the hand-tightened screw 740 to move it outward. At this time, the hand-tightened screw 740 is disengaged from the limiting hole 750, and then the slide frame 730 and the slide plate 720 can be removed. At this time, it is only necessary to install the slide frame 730 that adapts to linear guides 800 of different sizes. It can be seen that the entire device can be replaced and adapted according to linear guides 800 of different sizes, which significantly improves the adaptability of the entire device during use.
