New Description: [New Technology Field] This creation is about a linear drive system, especially a linear drive system with lead measurement capability that can measure the displacement of the slider body. [Prior Art] The machine tools produced by domestic manufacturers are of good quality and have been recognized by users in recent years and have a certain status in the international arena. The export value of machine tools has reached the fifth place in the world. In order to strengthen product competitiveness, it is an inevitable trend to develop more sophisticated and high-speed technology. The transmission mechanism in the tool machine is the core of it. There are many ways to operate the transmission, especially linear transmission systems. Among the various types of linear drive systems, linear guides are the most common, and are widely used in various types of machine tools or other automated industrial production equipment. Components such as rails, sliders, and balls are the basic components of linear slip. The guide rails are provided with slide grooves on opposite sides of the slider. The balls are held between the slider and the slide of the guide rail and circulate in the slider. As for the production technology of linear slide rails, such as the Republic of China Patent Publication No. 586584, the case has a return path in the slider body to guide the recirculation movement of the balls. The Republic of China Patent Notice No. 1230227 is for the improvement of the ball retainer. In addition, the No. 1221511 5 M284780 is provided with a matching oil tank on the side of the slider, and the oil storage material is stored in the oil storage box. In order to lubricate the balls inside the block. From the above-mentioned prior art, the basic operating principle of the linear slipper and its related constituent elements should be roughly understood. The prior art has proposed a number of techniques to improve the performance of linear slides; although the performance has indeed improved, how to achieve the displacement of the slider has become another challenge for current manufacturers. There are two methods for obtaining the displacement amount of the slider in the prior art. First, as shown in FIG. 1, a magnetic ruler 320 is attached to the guide 100, and the magnetic sensor 340 is mounted on the slider 200. When the slider 2 is moved, the amount of displacement of the slider 200 is obtained in accordance with the change in the magnetic field between the magnetic sensor 340 and the magnetic scale 320. The second method, as shown in Fig. 2, is to directly mark the scale 180 on the side of the guide rail 100, and then set the light sensor 420 on the slider 2''. Similarly, when the slider 200 is moving, the light sensor 420 will read the scale on the guide to know the amount of displacement of the slider 200. Domestic Shangyin Technology Co., Ltd. has such products. Although the above practice is indeed feasible, it has the following shortcomings. First of all, under the long use, the magnetic ruler 32Q will inevitably cause the shedding phenomenon and cause measurement error. Further, the length of the magnetic ruler 32() has its limitation and does not extend indefinitely. As for the first optical induction method, it is necessary to make two M284780 times of processing on the guide rail 100 and mark 180; however, the processing operation is quite time consuming, and the processing precision directly affects the accuracy of the measurement, and not all products can be used. use. Furthermore, the surface of the guide rail 100 during operation will be attached with foreign matter such as chips, oil or dust. Although both methods are non-contact measurement methods, the relevant manufacturers also claim that the measurement operation is not affected; Whether it is optical or magnetic measurement, it will still affect the measurement value. Finally, the components of the two measurement methods are quite sophisticated, resulting in costly and difficult maintenance replacement. [New content] In view of the lack of the prior art, this creation provides a linear transmission system with lead measurement performance, which can accurately measure the displacement of the slider body, and has the advantages of easy installation and maintenance, low production cost and the like. . According to the creation of the linear drive system with measurement performance, the slide rail, the slider body and the lead measuring device are mainly included. One of the guides is provided with a sliding groove, and the slider body is provided with a plurality of balls, which are placed on the guide rail in a linear reciprocating relationship. The lead measuring device is disposed on one side of the slider body, and has a tilting roller that normally contacts the guide rail, and an encoded display unit that is connected to the tilting roller. When the slider body slides relative to the guide, the tilting roller that abuts against the guide rail will be rotated together, and the code display unit will generate and display the displacement information of the slider body according to the amount of rotation of the tilting roller. The above and other objects, features, and advantages of the present invention will become more apparent and understood. [Embodiment] According to the linear transmission system with lead measurement performance disclosed in this creation, please refer to "3rd" to "5th" to explain the component composition and related configuration relationship. The creation mainly includes a guide rail 10, a slider body 20 and a lead measuring device 30. The sliding groove 12 is recessed on opposite sides of the guide rail 10. The slider body 20 is provided with a plurality of balls 26, and the ball 26 is held between the sliding slot 12 and the slider body 20, so that the slider body 20 can be straight. The relationship of the reciprocating motion is placed across the guide 10. The lead measuring device 30 is disposed on one side of the slider body 10, and mainly includes a tilting roller 32 and a code display unit 34. The tilting roller 32 normally interferes with the chute 12, which is covered with a rubber layer. The lead measuring device 30 includes a gear set that meshes with the tilting roller 32. By means of internal components such as a gear set, the code display unit 34 can know the amount of rotation of the tilting roller 32 and convert it. The displacement amount information of the slider body 20. The code display unit 34 is connected to the tilting roller 32 via the signal transmission extension line 35. The visual condition of the signal transmission extension line 35 is freely selected to an appropriate length, and the data is transmitted to the code display unit 34 for calculation and display. The lead measuring device 30 further includes a power storage unit 38 disposed inside the code display unit 34 to supply electrical energy required for operation. Of course, in the M284780, the power storage unit 3δ can also be omitted, and in the lead-one power line (not shown), the external power can be directly extracted, in addition to being in conflict with the fifth figure. In addition to the design of the chute 12, such as the preferred embodiment of the moving roller 32, the other one of the I, too much contact and the guide rail 10 shown in the circle, is in the technical field of the present invention. With the knowledge of (4) common knowledge, the assembly position of the tilting roller 32 is also adjusted.
