The guiding device uses a U-shaped guide outer rail 600 made of a steel material and a groove 65G on the side inner wall of the u-shaped guide outer 6 (8). The carrying platform _ is slidably disposed on the guide outer rail 600 1 ' between the balls. The balls are placed in the grooves 650 to cause the carrier platform 800 to slide along the guides 650 guiding the outer rails 6 through the guides of the balls 7. Since the ball 700 slides in a point contact manner, it has a low coefficient of friction (about 〇·〇4), and in addition, the ball 7〇〇 makes an infinite rolling cycle between the carrier platform 800 and the groove 650, so that The carrier platform 800 is capable of high precision and reversible linear motion along the trenches 650. Therefore, most of the conventional linear slide devices utilize the ball contact type of the point contact type to 亍 contact slide. However, this type of ball type design limits its load carrying capacity. At the same time, direct contact with metal is prone to local high stress, resulting in surface fatigue damage and wear. In addition, since the processing procedure of the ball is complicated in the production of the crucible, the processing f is relatively high. In addition, the molding size of the ball is designed according to the load carrying weight. Therefore, the volume phase occupied by the ball on the large machine is 5 The volume of the M328336 is also not only unable to effectively reduce the cost of the material used to make the ball. Even though the linear guide u that slides with the ball is used, it is not necessary to use such precision and sturdiness in various application fields; the linear sliding system of the shell, such as simple article transmission. Linear =:: Another set with lower processing cost and material cost 2, which makes it lighter in structure and smaller footprint with the existing linear sliding device using the ball. The necessity of development. [New content] Therefore, the purpose of this new type is to provide a linear guiding device that uses a friction-resistant material that is simple to process and has a low cost as a contact moving interface to achieve a large bearing capacity and a cost reduction effect. A linear guide according to the present invention includes a guide rail, a slider, and an f-grinding device. The slider is slidably disposed on the guide, and the cutting device is disposed on the slider and attached to the guide rail. The guide is provided with two recesses on both sides, and each recess is v-shaped inwardly concave. The slider is approximately gate-shaped and has two convex portions, wherein each of the convex portions is protruded from the V-shaped guide and corresponds to the two concave portions. Each of the convex portions has a first surface and a second surface, and the first surface and the second surface form an angle A. The range of the angle of loss A is less than 丨8〇. The slider has a mounting surface and a plurality of mounting holes for assembling the loaded objects. M328336 wear-resistant device is a plurality of wear-resistant pieces, and is disposed on the first surface and a first surface for surface-on-the-rail to reduce the grinding between the slider and the guide. Scratches such as SCraping are used to create special spots on the surface to increase contact quality and reduce friction. Therefore, the linear guiding device of the present invention has the following effects as compared with the conventional linear sliding device that uses the ball for contact sliding: 1. The linear guiding device of the present invention is provided by the wear-resistant piece provided on the convex portion. The punching is changed from the existing ball type point contact moving device to the surface contact moving, which can enhance the bearing capacity. 2. The linear guiding device of the present invention can reduce the weight of the structure and reduce the occupied volume under the same load specification according to the angle A of the convex portion designed to bear the force. 3. In the novel linear guiding device, the wear coefficient of the wear-resistant piece attached to the surface of the slider is lower than that of the conventional metal sliding rail after proper surface treatment, according to the experimental result, about 〜·〇2~0.05 The difference between the dynamic and static friction coefficients is about 0.015. Therefore, the slip retardation can be effectively reduced and the positioning accuracy can be increased.

Referring to Figures 4 and 5, there are shown cross-sectional views of embodiments of linear guides having different refresh angles A, respectively. In the embodiment of FIG. 4, the first surface 211 on the convex portion 2U) is parallel with the bearing surface on which the load is applied to form a smaller angle A (about 45 degrees), thereby achieving a larger Load bearing. Further, as shown in the embodiment of Fig. 5, the second surface of the convex portion 21 is changed to be parallel to the mounting surface 230 under the condition of an angle A with the angle A of Fig. 4. However, the actual angle of the angle A is still subject to actual conditions and adjustments required by the customer. Please refer to FIG. 3 and FIG. 6 , wherein FIG. 6 is a cross-sectional view showing the linear guiding device of the fourth embodiment of the present invention. The fourth embodiment is different from the first embodiment in that the concave portion 112 of the main body 11 is changed to the convex portion ι15 having the included angle A, and the original projection portion 21 of the slider 2 is formed into the concave portion 220. Each recess 220 has a first surface 221 and a second surface 222, and the wear plate 310 is disposed on the first surface 221 and the second surface 222. However, the actual implementation of the slider 200 and the guide rail 110 is still adjusted to the customer's needs and product design. The linear guiding device of the present invention has the following effects: 1. The linear guiding device of the present invention is changed from the existing ball-type point contact moving device to the surface contact movement by the design of the wear-resistant piece 310 disposed on the convex portion 21 Can improve the ability of carrying. 2. The linear guiding device of the present invention can reduce the size of the M328336 and reduce the occupied volume under the same load specification according to the angle A ′ of the convex portion 210 designed to bear the force. 3. In the linear guiding device of the present invention, the wear resistance of the wear-resistant piece 31 attached to the surface of the slider 2 after the appropriate surface treatment is lower than that of the conventional metal sliding, according to the experimental result, about 0 ·Between 02 and 〇〇5, * static and static: The difference between the coefficients is about G.G15. Therefore, it is possible to effectively reduce the slip block phenomenon and increase the positioning accuracy.
