Description

Linear slide platform dynamic rigidity and deviation monitoring system

The present invention relates to a linear slide rail platform dynamic rigidity and offset monitoring system, and in particular to a linear slide rail platform dynamic rigidity offset monitoring technology that can sense the multi-axis angle offset of the platform through a multi-axis angle offset sensing function to determine the dynamic rigidity and angle offset information of the platform during operation.

According to the market, linear slides mainly use rolling parts such as steel balls or rollers to circulate between the slide and the track, allowing the slide to perform high-precision and high-speed linear reciprocating motion along the slide. However, during the high-speed linear reciprocating motion, due to the friction and collision between the rolling parts and the slide, the linear slide is very easy to vibrate, which can easily cause the processing quality and service life to decrease. Therefore, various tests must be performed on the linear slide to meet the quality requirements. In addition, linear slides have the advantages of solid structure, small dynamic friction coefficient, large load-bearing capacity, simple installation, high positioning accuracy, and smooth transmission, so they have been increasingly widely used in the technical field of digital control machine tools. In addition, one of the key factors that affects the accuracy of the linear slide is the rigidity of the linear slide itself. Therefore, by monitoring and inspecting the rigidity of the linear slide, the accuracy of the linear slide displacement performance will inevitably be effectively improved.

As far as we know, if an external load (such as the load on the platform or the cutting force generated by the machine tool during the processing) is applied to the platform, the rolling element inside the linear slide will produce a slight elastic deformation phenomenon, but this elastic deformation phenomenon is not a permanent deformation. When the applied load force disappears, the rolling element will return to its original shape. Therefore, once the load force changes over time; or when the load force is of different sizes, the elastic deformation of the rolling element will affect the precision performance of the linear slide, thereby causing more inconvenience and trouble in the process. To solve this technical deficiency, most of the relevant linear slide technology field companies will improve the rigidity of the linear slide to solve this technical deficiency, mainly from the reduction of the elastic deformation of the rolling parts, the specific technical means are to change the geometric size, number, relative configuration and pre-stressing of the rolling parts to achieve this. Secondly, it is to improve the damping of the linear slide, through the damping setting to reduce the elastic deformation of the rolling parts, the specific technical means is to add several small surface contact sliding parts between the slider and the guide rail. Although the above-mentioned specific technical means can improve the rigidity of the linear slide and reduce the elastic deformation of the linear slide, the above-mentioned specific technical means do not have a linear slide platform dynamic rigidity and offset monitoring system, so that the currently used linear slide cannot be effectively detected in terms of its dynamic rigidity and multi-axis offset state, which makes it difficult to effectively improve the precision of the working platform during processing. Therefore, how to develop a linear slide rigidity and offset monitoring technology that can sense the multi-axis angular offset of the platform and obtain the dynamic rigidity and angular offset information of the platform when the slide assembly is running has become a technical issue that the relevant industry and academics are eager to solve and challenge.

In view of this, the above-mentioned known technical means are indeed not perfect in terms of dynamic rigidity and multi-axis offset detection, and there is still a need for further improvement. In addition, based on the urgent needs of the relevant industries, the inventors of the present invention have made continuous efforts to develop and finally developed a set of the present invention that is different from the above-mentioned known technology and the aforementioned patent.

The first purpose of the present invention is to provide a linear slide platform dynamic rigidity and offset monitoring system, which can mainly sense the angle offset of the multi-axis of the platform through the multi-axis angle offset sensing function setting, so as to obtain the dynamic rigidity and angle offset information of the platform when the slide assembly is running, thereby having the characteristics of reducing the deformation of the linear slide and increasing the rigidity and improving the displacement precision of the linear slide. The technical means for achieving the above-mentioned first purpose include a drive module, an X-axis angle deviation sensing module, a Y-axis angle deviation sensing module, a Z-axis angle deviation sensing module and an information processing module. The X-axis angle deviation sensing module is used for two first distance sensing signals. The Y-axis angle deviation sensing module is used for sensing two second distance sensing signals. The Z-axis angle deviation sensing module is used to sense two third distance sensing signals. The information processing module receives the X, Y and Z axis distance sensing signals through the signal transmission module, and converts and processes them into two first distance values, two second distance values and two third distance values in sequence. The information processing module performs difference calculations in sequence to obtain the first distance difference, the second distance difference and the third distance difference, and then determines whether the first distance difference, the second distance difference and the third distance difference corresponding to the X, Y and Z axes are higher than the reference distance difference. If the judgment result is yes, the output is the angle deviation warning information corresponding to the X, Y and Z axis angles when the slide assembly is running.

The second purpose of the present invention is to provide a dynamic rigidity and offset monitoring system for a linear slide platform that can simulate the actual load operation of the linear slide platform by selecting the required load center of gravity point and load state to obtain more accurate distance differences of each axis. The technical means for achieving the aforementioned second purpose include a drive module, an X-axis angle deviation sensing module, a Y-axis angle deviation sensing module, a Z-axis angle deviation sensing module and an information processing module. The X-axis angle deviation sensing module is used for two first distance sensing signals. The Y-axis angle deviation sensing module is used for sensing two second distance sensing signals. The Z-axis angle deviation sensing module is used for sensing two third distance sensing signals. The information processing module receives the distance sensing signals of the X, Y and Z axes through the signal transmission module, and converts and processes them into two first distance values, two second distance values and two third distance values in sequence. The information processing module performs difference calculation in sequence to obtain the first distance difference value, the second distance difference value and the third distance difference value, and then determines whether the first distance difference value, the second distance difference value and the third distance difference value of the X, Y and Z axes are higher than the reference distance difference value. If the judgment result is yes, the output is the angle deviation warning information corresponding to the X, Y and Z axis angles when the slide assembly is running. The load applying device further comprises a load surface on the top of the platform, which is divided into a plurality of load areas. The load applying device is used to sequentially apply load forces to the plurality of load areas of the platform to simulate the reciprocating movement of the platform relative to the slide assembly. When the load force is applied to each load area in sequence, the first distance difference, the second distance difference and the third distance difference of the platform in each load area corresponding to the X, Y and Z axes when the slide assembly is running are sequentially obtained.

The third purpose of the present invention is to provide a linear slide platform dynamic rigidity and offset monitoring system that can simulate the actual load operation of the linear slide platform by selecting the required load center of gravity point and load state to obtain more accurate distance differences of each axis. The technical means for achieving the aforementioned third purpose include a drive module, an X-axis angle deviation sensing module, a Y-axis angle deviation sensing module, a Z-axis angle deviation sensing module and an information processing module. The X-axis angle deviation sensing module is used for two first distance sensing signals. The Y-axis angle deviation sensing module is used for sensing two second distance sensing signals.
