Description

Technical Field

[0001] The present application relates to the technical field of linear guide rail production and processing, and in particular to a linear guide rail strength detection device. Background Art

[0002] Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving parts to perform reciprocating linear motion in a given direction. During production, in order to prevent deformation and other problems in later use, the guide rails need to be strength tested. Therefore, a linear guide production strength testing device is needed.

[0003] At present, the strength test of linear guide rails is of vital importance. Linear guide rails play a key guiding and supporting role in mechanical equipment. First of all, high-strength linear guide rails can ensure the stability and precision of the equipment during operation. If the guide rail strength is insufficient, it may deform when bearing load, resulting in deviations in equipment operation, affecting product quality and production efficiency. Secondly, strength testing can detect potential defects of the guide rails in advance, avoid sudden damage in actual use, reduce the risk of equipment failure, and reduce maintenance costs and downtime. Moreover, for applications in some special fields, such as high-precision machine tools and automated production lines, extremely high strength requirements are placed on linear guide rails. Only by passing strict strength testing can the equipment be guaranteed to operate reliably under long-term, high-load working conditions. Finally, strength testing also helps to promote the continuous advancement of linear guide rail production technology, prompting manufacturers to improve product quality and meet the needs of different industries.

[0004] In the inspection process of linear guide rails, inspection equipment is usually used to assist. Most existing inspection equipment uses a motor-driven lead screw to drive the fixture to position the guide rail. After the guide rail is positioned, a strength test is performed. However, in such a processing process, the guide rail body is usually in a fixed state. When the inspection position of the guide rail body needs to be adjusted, the guide rail can only be removed and reinstalled to adjust the position before it can be inspected again. Obviously, this method is extremely cumbersome and inconvenient to operate as a whole. It cannot flexibly adjust the position of the guide rail, and it is not convenient to inspect any position on the top of the guide rail. It can be seen that the existing inspection method has certain defects, and it is urgent to improve and optimize it to improve the efficiency and accuracy of guide rail inspection and meet the needs of actual production applications.

The outer ends of the tops of the two rear limit frames 340 of the four limit frames 340 are fixedly connected to second motors 360. The output end of the second motor 360 extends through the tops of the limit frames 340 and is fixedly connected to the guide wheels 350. In the drive mechanism 500, the movable track 510 provides a stable operating environment for the lead screw 530 and the slider 540. The first motor 520 drives the lead screw 530, whose threads rotate in opposite directions at both ends, to rotate, accurately controlling the sliding of the slider 540 within the movable track 510, thereby driving the synchronous movement of the clamping mechanism 300 and achieving accurate clamping and positioning of guide rails of different sizes.

The second motor 360 can directly drive the guide wheel 350 to rotate. On the one hand, it facilitates the lateral displacement of the guide rail body 400, so that the pressure head 240 can detect any position on the top of the guide rail body 400, thereby improving the comprehensiveness of the detection; on the other hand, it can realize the insertion of the guide rail body 400 from one side and the discharge of the blanking from the other side, and perform continuous and uninterrupted detection, which is suitable for longer guide rail bodies 400, thereby improving the detection efficiency and adaptability of the device as a whole.

[0032] The inner side of the receiving plate 330 is provided with an empty groove 370, and the inner side of the empty groove 370 is rotatably connected to the guide roller 380, the outer surface of the guide wheel 350 is fitted and connected to the two sides of the guide rail body 400, the top of the guide roller 380 is fitted and connected to the bottom of the guide rail body 400, and the bottom of the side plate 320 is fixedly connected to the guide block 560, and the top two sides of the base plate 100 are fixedly connected to the supporting guide rail 550, and the guide block 560 is slidably connected to the inner side of the supporting guide rail 550.

[0033] The principle and advantages of use are as follows: during use, the guide rail body 400 to be inspected can be placed on the receiving plate 330 inside the clamping mechanism 300, and by starting the first motor 520 to run, the first motor 520 can drive the screw rod 530 to rotate, and while the screw rod 530 rotates, it can also synchronously drive the sliders 540 at both ends of the movable track 510 to slide. Since the threads at both ends of the screw rod 530 rotate in opposite directions, it can assist in synchronously driving the two clamping mechanisms 300 to move relative to each other. When the clamping mechanisms 300 move relative to each other, they can assist in clamping the guide rail to be inspected. During this period, the telescopic cylinder 220 can be started to push the pressure head 240 at the bottom of the pressure sensor 230 to detect the guide rail body 400. When the shape of the guide rail body 400 changes, its pressure resistance data can be measured to obtain its maximum pressure resistance. At the same time, during normal quality inspection, it is only necessary to operate the telescopic cylinder 220 to run to the required pressure resistance. At this time, if the guide rail body 400 is not deformed, it is qualified. On the contrary, if it is deformed, it is unqualified. It can be seen that the device as a whole can efficiently realize the function of automatically testing the guide rail strength.

[0034] By setting up the clamping mechanism 300, the device shows strong flexibility and adaptability during use. The first motor 520 is used to drive the screw rod 530 to drive the slider 540 to slide, and then the two connecting arms 310 can be adjusted to move with each other. The two connecting arms 310 move with each other, which can assist in pushing the side plate 320 and the receiving plate 330 inward. At this time, the guide rail body 400 to be inspected is placed on the top of the receiving plate 330. As the two receiving plates 330 move inward, the guide rail body 400 can be clamped by the limit frame 340. During this period, since the guide wheel 350 is in contact with both sides of the guide rail body 400, the two sides of the guide rail body 400 can be limited and clamped, and the bottom of the guide rail body 400 is supported by the receiving plate 330, which can cause the guide rail body 400 to be stably located on the inner side of the two clamping mechanisms 300. In addition, the adjustable spacing design in this process enables the device to flexibly adapt to the inspection of guide rail bodies 400 of different sizes. If it is necessary to adjust the pressure resistance of different positions on the top of the guide rail body 400, the second motor 360 can be started to operate. The second motor 360 can directly drive the guide wheel 350 to rotate. At this time, on the one hand, the bottom of the guide rail body 400 is in contact with the guide roller 380, and the guide roller 380 rotates inside the empty groove 370. At this time, the guide roller 380 is in contact with the bottom of the guide rail body 400, which can help reduce the friction at the bottom of the guide rail body 400, so that the guide rail body 400 can be stably displaced left and right. At this time, as the second motor 360 drives the guide wheel 350 to rotate, the guide wheel 350 and one side of the guide rail body 400 are in contact with each other. The guide rail body 400 is connected to the guide wheel 350 on one side and can be driven to move laterally. Therefore, the device can flexibly adjust the lateral position of the guide rail body 400, so that the pressure head 240 can detect any position on the top of the guide rail body 400, and the device can perform rapid and comprehensive detection. Moreover, driven by the guide wheel 350, the guide rail body 400 can be inserted from one side between the inner sides of the two clamping mechanisms 300, and then the blanking is discharged through the guide wheel 350, so that continuous and uninterrupted rapid and comprehensive detection can be achieved. At the same time, longer guide rail bodies 400 can also be detected, and the overall adaptability is stronger.
