Description of the Invention: [Technical Field] The present invention relates to an impediment mounted on a machine tool and used for carrying heavy objects, and more particularly to a CNC machine tool motion track device. [Prior Art] Referring to Figures 1 and 2, there is a conventional CNC machining machine 1 having a base 11, a fixed table 12 mounted on the base, and a movable relative to the fixed table 12. And a work platform 13 for the workpiece to be locked. The fixing table 12 has two first supporting surfaces 121, two second supporting surfaces 122, and two third supporting surfaces 23. The working platform 13 has a first contact surface 131 that is in sliding contact with the first supporting surfaces 121 by two adjusting blocks 200, and a second contact surface that is in sliding contact with the second supporting surfaces 122, respectively. 132, and two third contact faces 133 that are in sliding contact with the third support faces 123, respectively. The adjustment block 2 is also provided between the second branch surface 122 and the adjacent first contact surface 132. When the processing machine 1 processes the workpiece 1 to be processed, the operation is flat. 3 is movable relative to the fixed table 12, at this time, the first contact faces 1 are in sliding contact with the first support faces 121 by four blocks 200 to be in sliding contact with the second contact face 132 and the adjacent one. The second supporting surface 122 is in monthly contact with the second contact surface 132, and the second contact surface 132 is in sliding contact with the second supporting member 122 in the indirect direction by the block 200. The third pushing surface 123 is frictionally and slidingly contacted, and the contact surface of the third pushing surface 123 can be guided by the outer surface of the working platform 13 and the fixed table 200836871 12, and the larger contact area can be used. The compressive stress generated by reducing the weight w of the workpiece 100 (the contact surface unit area is stressed) 〇 due to the contact between the working platform 13 and the fixing table 12, the contact surfaces 131, 132, 133 and the The large area contact of the support surfaces 121, 122, 123 is however 'however, the large area contact increases the frictional resistance, making the moving speed of the working platform 13 relative to the fixed stage 12 slow, and the processing speed becomes slower. Referring to Fig. 3', there is another fixed stage 12' installed in the processing machine 1, and a movable working platform 13 is movable relative to the fixed table 12. The fixed table 12 and the working platform 13 are slidably connected by a linear sliding knob. Each of the linear sliders 14 has a stop 141 that is locked to the fixed table 12, and the number of times is locked. a sliding block 13 , a slider 142 , and a plurality of balls 143 〇 the balls 143 and the obstruction 141 , the sliders 142 are in small area contact, so the friction is small, the work The platform 13 can be moved quickly relative to the fixed table 12, so that the processing speed can be effectively increased, and the linear slider 14 can also guide the satellite platform 13 at the same time, and move relative to the fixed table 12 to ensure a straight line. The accuracy of the movement. (4) The small rails are connected to the rails (4) and the sliding surfaces, so that the compressive stress of the balls 143, the rails i4i, and the sliders 142 are increased, and the balls are enlarged. (4) The wear of the tracks (4) and the surfaces of the sliders 142 is intensified, in particular, the weight W of the workpiece to be processed is heavier or after a long time of use, the machining accuracy is lowered due to the wear of the contact surface. And shorten the service life of the machine tool 1. Therefore, the manufacturer replaces the balls 143 of the linear slide rails 14 with rollers (not shown). Since the cylinders of the rollers are slightly parabolic curved surfaces, the rollers and the rails 141, etc. The contact of the slider 142 is a trace line contact, and the roller has a larger contact area than the small area contact of the balls 143, so that the compressive stress of each component can be relatively reduced, thereby slowing the wear rate of the surface. However, if the weight w of the workpiece 1 is heavy and after long-term use, the problem of lowering the processing accuracy caused by the surface wear of the components of the linear slide 14 cannot be effectively solved. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a CNC machine tool that can reduce wear and can carry a heavy workpiece to be processed, and can quickly move the workpiece to be processed. Therefore, the CNC machine tool motion track device of the present invention comprises a fixed table, a sliding table, and two sliding track units. The fixing table is mounted on the CNC machine tool and has two supporting surfaces arranged in a row and two mounting portions parallel to the supporting surfaces. The sliding table y moves along the supporting surface with respect to the fixed table, and has two sliding surfaces respectively corresponding to the supporting surfaces, and two fixing portions respectively corresponding to the mounting portions, and the sliding rail units are mounted on the sliding rail unit Between the fixed table and the sliding table, each of the sliding rail units has a track, at least one slider that is slidably engaged with the track, and two rolling components between the track and the sliding block. Is a mounting portion connected to the fixed table, the slider is a 200836871 fixing portion connected to the sliding table, and when the sliding table is subjected to a load and moves relative to the fixed table, the sliders are respectively opposite to the tracks Sliding, the sliding surfaces are in sliding contact with the supporting surfaces, respectively, and the rolling components are rolled between the tracks and the sliders.

In this embodiment, the first rail units 43 are substantially linear rails, and the similar functions of the 4th moon rails are not mentioned here. The U-slide unit 33 is not mentioned here. Referring to Figures 5, 6, and 11', the third motion track device 5 includes a third fixed platform 51, a third sliding table 52, and two third sliding units. The first::= is installed on the vertical shaft 22, and has two locking blocks 510 integrally connected to the second fixing opening 51, and two secondly formed on the locking blocks 5Η) Three swing faces 511, and two third mounts that are parallel to the third swing faces 511 and are spaced apart—(four) 'where the third treads 44 and the second t-mounts 512 all extend parallel to the two axes. The second sliding table 52 can be moved up and down with respect to the second fixed stage 51 parallel to the z-axis and 200836871 along the third supporting surface 511. The implementation table 52 is for the lifting seat 23 When the slide is moved, the spindle is also driven to move with the upper τ. The third eight-two does not correspond to and contacts the third core faces 521' and two respectively corresponding to the first mounting portion 522 of the third mounting portion (1). By slidingly contacting the third sliding surface 521 of the third movable opening 511 at the locking block 51 ^ a port (4) ^, the moon can be slidably restrained. ^ ° 52 One of the third rail units 53 is mounted between the third fixed table and the second sliding table 52, and each of the first = "" The rail has a third slider 532 that is slidably engaged with the second lane 531, and a third roller assembly 533 that is located at the same mother-third rail 531 and each of the third sliders 532. The third lane 531 is 531. The third mounting portion 512 is locked to the third fixing base 51. The third sliding portion 532 is a third fixing portion 522 that is locked to the third sliding table 52. In the present embodiment, the third slide unit 53 is substantially linearly slipped and has similar functions as the first slide unit 33, and is not described herein again, and the g_一―, The motion principle and function of the three motion-carrying devices 4, 5 are the same. Therefore, the following description will only explain the principle of operation of the first motion-track device 3, and the second and third motion-track devices 4, 5 Only shown in Figures 4, 5, 6, 10, and 11. Referring to Figures 4, 5, 1 and u, the machine tool 2 can be driven by a first-to-one motor 24, 25, 26, respectively. The first, second and third screws 27 28 29 pivot to respectively drive the first and second sliding tables 32, 42 relative to 12 200836871 three sliding ^ 2 = two two = X' Y _, and drive the first her mountain from, τ > ; God J 1 is moved by the Χ, Υ axis =: face, and the lifting seat 23 can be moved up and down to make the processing master, read the object to be processed 2GG, and the light to be processed into the workpiece 200. The workpiece 5, 7, 9' is added to the first sliding table 32 before the processing of the 31 machine 2, and then, when the first, the first to the first sliding 32 is parallel to the first-stage 31 χ = time: the first slider 332 of the first slide unit 33 is slid relative to the first track 331. If the gravity of the object to be processed is small, due to 1 The first rolling element 333 is in contact with the first track 331 and the first sliding block 332 in a small area, so that the frictional resistance caused by the first sliding track unit 33 is small, so that the first sliding table 32 can be opposite. The first fixed stage 31 moves rapidly. If the gravity W1 of the workpiece is large, the first scroll 333 is in contact with the first track 331 and the first slider 332 in a small area. The compressive stress of the ball of the equal-rolling component 333 is relatively large, causing the balls of the first-rolling component 333 to be slightly elastically deformed (not shown), thereby causing the first sliding table 32 to face the first fixed table. Η slight shift, and close, because the first sliding surface 321 , the first supporting surface 3 ιι is in sliding contact 'the gravity W1 of the workpiece 2 也 is also the first sliding surface 321 , The abutment of the two sides of the _ branch floor 311 to share the branch. Because of the first-sliding surface 321, the The first contact surface 311 has a contact area farther than the distance of the first rolling element 333 and the contact area of the first track and the moon/ghost 332, so that the bearing surface 311 can withstand greater pressure and effectively share the contact area. The gravity wi of the first sliding rail unit 33 is reduced. Thus, the compressive stress of the first rolling components 333 is reduced, thereby reducing the surface wear of the first sliding unit 33 and prolonging the service life. It is known that the frictional contact area between the first sliding table 32 and the first fixed table 31 is reduced, so that the speed at which the first sliding table 32 moves relative to the first fixed table Η f can be increased. Through the above description, the advantages of the present invention can be further summarized as follows: First, the first exercise device 3 of the present invention is provided by the first support surface 311 and the first sliding surfaces 321 The contact assists the first/month T unit 33 to jointly support the gravity π! of the workpiece 2〇〇, compared to the conventional two, the invention can carry a larger gravity W1, avoiding an excessive load Problems such as friction loss and shortened service life. The second and third motion track devices 4, 5 of the present invention also have the same effect. Secondly, the frictional contact surface of the first exercise device 3 of the present invention has only one first support surface 311 and two first sliding surfaces 321 , that is, four ® contacts, compared with the Knowing the frictional contact (see 0 2), that is, two first and second support faces 121, 122, 123, two first, two, three contact faces 131, 132, 133, a total of 12 faces, this The frictional contact area of the invention is relatively small, so that the frictional force is small, so that the first slide table 32 can move relative to the first solid stage 31 more quickly. The second and third motion track devices 4, 5 of the present invention also have the same effect. It is to be understood that the present invention may have the following design changes: 14 200836871 Referring to Figures 7, 10, and U, the first, second, and third rolling components of the mvr are 533, and most of the balls are used. In practice, if you use / generation (see Figure 12) 'or mix the ball with the roller (not shown)' also has the same effect. *Incorporating the CNC machine tool motion track device of the present invention, by the equal π rail early το 33, the first support surface 311 and the first sliding surface 321 at the same time 6 are placed together to share The fine gravity wi' of the workpiece to be processed reduces the wear of the first rail unit 33, and thus can carry a large gravity and can move the first sliding table 32 rapidly relative to the first fixed table 3i. The second and third motion track devices 4, 5 also have the same effect, so it can indeed achieve the purpose of the invention. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
