Description

Technical Field

[0001] The present invention relates to the technical field of linear guide rail detection, and in particular to a linear guide rail smoothness detector. Background Art

[0002] In the field of industrial manufacturing, precision linear motion is an extremely important link in many key areas such as machine tool equipment processing, automated production and manufacturing transportation, precision testing instruments, and semiconductor manufacturing equipment, and linear guides are an indispensable core component of precision linear motion equipment. Linear guides are assembled from guide rails and sliders. Whether the movement of guide rails, balls, and sliders is smooth after assembly will directly determine whether the product quality meets the standards, and will indirectly affect its actual use performance when assembled to precision motion modules of other equipment. Therefore, after the assembly process of the linear guide is completed, the smoothness of the operation of the assembled guide rails must be accurately tested immediately to ensure the product's factory qualification rate and to ensure that the expected results can be achieved when it is subsequently delivered to customers for use, providing stable and reliable linear motion support for customers' production operations, thereby improving the overall operation quality and efficiency of industrial manufacturing production lines.

[0003] At present, in the process of detecting the smoothness of the linear guide by the detection device, the detection device adopts the form of a dynamometer with a number of combined connectors to establish a connection relationship with the slider of the linear guide. In this connection mode, the traction force applied by the dynamometer causes the slider to move in the left and right directions, and the smoothness of the slider movement throughout the process is detected, and the final judgment conclusion is made based on the digital range displayed by the dynamometer. However, among the common linear guide models on the current market, the linear guides of different specifications are set differently, and most of them do not have a part for the dynamometer to connect and fix. Even if it exists, its purpose is not for connection, but to serve the oiling operation inside the slider, so it cannot be used directly for connection purposes. And once the wrong connection is made, it is very likely to cause a series of subsequent problems, which will have a potential adverse effect on the service life of the entire linear guide, such as causing increased wear of the connection parts and affecting the stability of the internal structure, thereby shortening the normal operation cycle of the linear guide, increasing equipment maintenance costs and downtime risks, and hindering the continuity and efficiency of industrial production.

[0004] Therefore, it is very necessary to propose a linear guide smoothness tester that can utilize the slider of the linear guide to establish a connection relationship and facilitate the detection of linear guides of different specifications. Summary of the invention

[0019] The clamping module includes a fixed clamping member 18, a servo 19, a crank 20 and a movable clamping member 21. The fixed clamping member 18 is fixedly connected to the supporting plate 3 and is located above the supporting plate 3. The movable clamping member 21 is slidably connected to the first linear guide rail 2. The servo 19 is electrically connected to the linear motor 6. The crank 20 is respectively connected to the movable clamping member 21 and the servo 19.

[0021] Furthermore, the clamping module further includes a first photoelectric sensor 22 and a second photoelectric sensor 23 . The movable clamping member 21 is provided with the first photoelectric sensor 22 , and the fixed clamping member 18 is provided with the second photoelectric sensor 23 .

[0022] In this embodiment, the first photoelectric sensor 22 fixed on the movable clamp 21 and the second photoelectric sensor 23 on the fixed clamp 18 are used to automatically detect the length of the linear guide 9 to be tested. In the operation test process, the manual measurement of the length of the linear guide 9 to be tested, input and other tedious operations can be completely omitted. Instead, the linear guide 9 to be tested can be directly placed, and the length of the linear guide 9 to be tested can be measured and then the smoothness test can be performed.

This not only limits the spatial freedom of the linear guide 9 to be tested that must be restricted during the detection process, but also can adapt to linear guides 9 to be tested of different specifications to a certain extent. If necessary, it is only necessary to replace the corresponding pins to cooperate with the mounting holes on the linear guide 9 to be tested.
