[0031] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0032] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In order to make the content of the present invention more clearly and more accurately understood, it will now be described in detail with reference to the accompanying drawings. The accompanying drawings in the specification illustrate examples of embodiments of the present invention, wherein the same reference numerals represent the same elements. It is understood that the scales shown in the accompanying drawings in the specification are not the scales of the actual implementation of the present invention, and are only for the purpose of illustrative description, and are not drawn according to the original size.

[0036] Please see Figure 1 The present invention provides a machine tool body, including a column 100, a slide body 200, a slider assembly 300 and a guide rail assembly 400.

[0037] In order to facilitate the installation of the guide rail assembly 400 on the column 100, the column 100 is a wall-type column 100. The characteristic of the wall-type column 100 is that the value of the horizontal length is similar to the value of the vertical height. That is to say, the horizontal extension length of the wall-type column 100 is greater than that of an ordinary column, so that a guide rail extending in the horizontal direction can be installed on the column. Since the horizontal length of the wall-type column 100 is extended, the column as a whole can absorb more cutting force and has a better anti-seismic effect. Figure 1 The extension direction of the middle guide rail assembly 400, the vertical direction refers to the extension direction of the guide rail on the front side of the slide body 200. It can be understood that the front side of the slide body 200 is for the spindle box to slide and install. The longitudinal direction refers to the direction perpendicular to the front side of the slide body 200. The guide rail installed on the front side of the column 100 in the slider assembly 300 is located between the column 100 and the slide body 200 in the longitudinal direction. The guide rail installed on the top surface of the column 100 in the slider assembly 300 is located between the column 100 and the slide body 200 in the vertical direction.

[0038] In order to facilitate the installation of the guide rail assembly 400 on the column 100, the column 100 is provided with a guide rail mounting portion 110, and the guide rail mounting portion 110 is used to mount the guide rail assembly 400. It can be understood that in order to reduce the error of assembling the guide rail assembly 400 with the column 100, the requirement for the flatness of the guide rail mounting portion 110 will be as high as possible, so that when the guide rail assembly 400 is installed on the guide rail mounting portion 110, the installation error of the guide rail assembly 400 and the guide rail mounting portion 110 is largely guaranteed to be within the tolerance range, thereby improving the qualified rate of assembling the guide rail assembly 400 with the guide rail mounting portion 110.

[0039] Please see Figure 2 , 3 And 4. In order to facilitate the column 100 to better support the skateboard body 200, the column 100 includes a top surface 101 and a front side surface 102 that are connected to each other, and the guide rail mounting portion 110 includes a first guide rail mounting portion 111 located on the top surface 101 of the column 100, a second guide rail mounting portion 112 and a third guide rail mounting portion 113 located on the front side surface 102 and spaced from each other, so that the first guide rail mounting portion 111 on the top surface 101 of the column 100 can be supported below the top of the skateboard body 200, and the effect of supporting the skateboard body 200 is better, avoiding the occurrence of the adverse phenomenon of greater forward tilt caused by the traditional skateboard body 200 being hung on the side of the column 100.

[0040] The skateboard body 200 is slidably connected to the column 100 via the slider assembly 300 and the guide rail assembly 400. In this embodiment, the skateboard body 200 is slidably connected to the column 100 in a transverse direction.

[0041] Please see Figure 6 In order to adapt the slider assembly 300 to be installed on the column 100 in more ways, a support portion 114 is provided at the bottom of the column 100. It can be understood that the material of the support portion 114 can be the same as or different from that of the column 100, as long as the support portion 114 can be vertically arranged at the bottom of the front side of the column 100, so that the support portion 114 can be supported on the bottom of the skateboard body 200, and the gravity of the skateboard body 200 can fall on the support portion 114, thereby avoiding the forward tilting phenomenon caused by hanging the skateboard body 200 on the column 100 in the traditional way, ensuring that the column 100 supports the skateboard body 200 more stably, improving the stability of the skateboard body 200 sliding relative to the column 100, avoiding the torsion of the guide rail assembly 400, preventing the accelerated wear of the guide rail assembly 400, and preventing the slider assembly 300 and the guide rail assembly 400 from making abnormal noises when sliding, thereby extending the service life of the guide rail assembly 400 and the slider assembly 300.

[0042] Please see Figure 1, the assembly relationship between the guide rail assembly 400 and the guide rail mounting portion 110 is introduced below, the guide rail assembly 400 is installed on the guide rail mounting portion 110, the guide rail assembly 400 includes a first guide rail 410, a second guide rail 420 and a third guide rail 430 respectively arranged on the first guide rail mounting portion 111, the second guide rail mounting portion 112 and the third guide rail mounting portion 113, the slider assembly 300 is slidably arranged on the first guide rail 410, the second guide rail 420 and the third guide rail 430; in this embodiment, the slider assembly 300 also includes a second slider 320 slidably arranged on the second guide rail 420 and a third slider 330 slidably arranged on the third guide rail 430.

[0043] Please see Figure 5 In this embodiment, any two of the first guide rail 410, the second guide rail 420 and the third guide rail 430 are not coplanar, so that the problem of being unable to provide support to multiple surfaces of the skateboard body 200 caused by installing two guide rails at intervals on the same plane can be avoided, and the stability of the sliding connection between the column 100 and the skateboard body 200 is improved, wherein g1 is the center of mass of the skateboard body 200, g2 is the vertical plane where the first guide rail 410 is located; g3 is the vertical plane where the third guide rail 430 is located, and also the diversity of the position selection of the guide rail assembly 400 and the slider assembly 300 between the skateboard body 200 and the column 100 is improved, making the installation of the slider assembly 300 and the guide rail assembly 400 more flexible.

[0044] Specifically, the first guide rail 410 and the third guide rail 430 are respectively located on both sides of the second guide rail 420. It can be understood that the first guide rail 410 and the third guide rail 430 are respectively located on both sides of the second guide rail 420 in the vertical direction. The bottom of the column 100 is provided with a support portion 114 for mounting the third guide rail 430. It can be understood that the support portion 114 and the column 100 can be integrally formed, so as to facilitate the manufacture of the column 100, improve the production capacity of the column 100, and also facilitate the formation of the support portion 114 at the bottom of the column 100. The guide surfaces of the first guide rail 410 and the third guide rail 430 are oriented in the same direction, the guide surface of the second guide rail 420 is perpendicular to the guide surface of the first guide rail 410, and the center of mass g1 of the skateboard body 200 is located between the vertical plane g2 where the first guide rail 410 is located and the vertical plane g3 where the third guide rail 430 is located, which conforms to the traditional column 100-lifting type support of the skateboard body 200, so that the center of gravity of the skateboard body 200 falls on the structural parts of the column 100, preventing the skateboard body 200 from hanging sideways on the column 100, thereby improving the stability of the column 100 supporting the skateboard body 200.

[0045] Please see Figure 6In some embodiments, in order to strengthen the supporting force between the bottom of the skateboard body 200 and the column 100 and improve the stability of the connection between the bottom of the skateboard body 200 and the column 100, so that the skateboard body 200 is more stable when sliding relative to the column 100, the second guide rail 420 and the third guide rail 430 are located on the same plane, and the first guide rail 410 is not coplanar with the second guide rail 420 or the third guide rail 430; it can be understood that z1 is the supporting normal of the third guide rail 430. In the prior art, there is a solution in which only one guide rail is set between the front side of the column 100 and the skateboard body 200. The load borne by a single guide rail is too heavy, which can easily accelerate the forward tilt of the skateboard body 200 relative to the column 100, and also accelerate the wear of the guide rail, and the repeat processing accuracy cannot be guaranteed.

[0046] Specifically, the first guide rail 410 and the third guide rail 430 are respectively located on both sides of the second guide rail 420 . It can be understood that the first guide rail 410 and the third guide rail 430 are respectively located on both sides of the second guide rail 420 in the vertical direction. The second guide rail 420 and the third guide rail 430 are both hung on the front side surface 102 of the column 100, and the support normal of the third guide rail 430 is located below the center of mass of the skateboard body 200. The second guide rail 420 and the third guide rail 430 are jointly supported between the side of the skateboard body 200 and the front side surface of the column 100, and the load of the skateboard body 200 can be jointly borne by the second guide rail 420 and the third guide rail 430. Compared with the solution of a single guide rail, the second guide rail 420 and the third guide rail 430 can share the load, and each of the second guide rail 420 and the third guide rail 430 can withstand less load. During the process of machining workpieces by the machine tool, the sliding speed of the second guide rail 420 and the third guide rail 430 will be faster, and the moving speed of the skateboard body 200 will be faster, thereby improving the machining efficiency of the machine tool.

[0047] Please see Figure 1 In the case where the skateboard body 200 is tilted forward relative to the column 100, and a second guide rail 420 and a third guide rail 430 are provided between the front side surfaces of the skateboard body 200 and the column 100, how to adjust the parallelism between the second guide rail 420 and the third guide rail 430 and the second slider 320 and the third slider 330 respectively, so that the skateboard body 200 can slide in a straight line when sliding relative to the column 100, avoid twisting of the guide rail assembly 400 itself, and ensure the stability of the sliding of the skateboard body 200 relative to the column 100.

[0048] Please see Figure 1 , 2And 4. Since the guide rail assembly 400 includes at least three guide rails, the installation of each guide rail will affect the parallelism between the skateboard body 200 and the column 100. In order to ensure the parallelism between the skateboard body 200 and the column 100, the machine tool body also includes an adjustment assembly 500. The adjustment assembly 500 is arranged between the slider assembly 300 and the skateboard body 200. The adjustment assembly 500 is used to adjust the parallelism between the skateboard body 200 and the column 100 along the vertical and / or horizontal direction. By setting the adjustment assembly 500, the parallelism between the skateboard body 200 and the column 100 can be ensured, thereby ensuring the sliding stability between the skateboard body 200 and the column 100 and improving the repeatability of the machine tool.

[0049] The installation position of the adjustment assembly 500 is described in detail below. Since the second slider 320 and the third slider 330 are arranged on the front end surface of the column 100, the adjustment assembly 500 is installed on the second slider 320 or the third slider 330. In this embodiment, the adjustment assembly 500 includes a first group of adjustment mechanisms 510 and a second group of adjustment mechanisms 520, each of which is composed of two adjustment mechanisms. The two adjustment mechanisms are symmetrically arranged on both sides of the second slider 320 or the third slider 330; each adjustment mechanism includes two adjustment members 530 located on the same side of the second slider 320 or the third slider 330, so that a squeezing force can be applied to the upper and lower sides of the second slider 320 and the upper and lower sides of the third slider 330, so that the positions of the second slider 320 and the third slider 330 and the second guide rail 420 and the third guide rail 430 can be adjusted respectively, thereby adjusting the parallelism of the slide body 200 relative to the column 100.

[0050] The specific structure of the adjustment member 530 is introduced below. In this embodiment, the adjustment member 530 includes a lifting member 531 for lifting the slider assembly 300, a mounting member 532 for mounting the lifting member 531, and a fixing member 533 for fixing the mounting member 532 to the skateboard body 200. The mounting member 532 is fixed to the skateboard body 200 via the fixing member 533, and the lifting member 531 is threadedly connected to the mounting member 532.

[0051] In some other embodiments, in order to adjust the pre-pressure between the lifting member 531 and the mounting member 532, thereby ensuring that there is external force tension between the lifting member 531 and the mounting member 532, ensuring the stability of the installation between the lifting member 531 and the mounting member 532, and preventing the lifting member 531 and the mounting member 532 from loosening, the adjustment member 530 includes a lifting member 531 for lifting the slider assembly 300, a mounting member 532 for installing the lifting member 531, a fixing member 533 for fixing the mounting member 532 to the skateboard body 200, and an elastic member arranged between the lifting member 531 and the mounting member 532, and the elastic member adjusts the pre-pressure between the lifting member 531 and the mounting member 532 by adjusting the pre-tightening force.

[0052] Please see Figure 1 , 2 And 3, in order to adjust the parallelism of the slide plate body 200 relative to the column 100 in the horizontal direction, the machine tool body also includes a stopper 600, the slider assembly 300 includes a first slider 310 slidably arranged on the first guide rail 410, one side of the stopper 600 is connected to the slide plate body 200, and the other side of the stopper 600 abuts against the first slider 310, and the stopper 600 is used to adjust the parallelism of the slide plate body 200 with the column 100 in the horizontal direction. It can be understood that by adjusting the abutment force between the stopper 600 and the first slider 310, the inclination of the first slider 310 is adjusted, thereby adjusting the parallelism of the slide plate body 200 connected to the first slider 310 relative to the column 100.

[0053] The specific structure of the slide body 200 is introduced below. In this embodiment, the slide body 200 includes a horizontal body 210 and a vertical body 220 connected to each other. It can be understood that the vertical body 220 is fixed to the top of one side of the horizontal body 210, so that a vertical structure is formed between the horizontal body 210 and the vertical body 220, which is convenient for installing the slide body 200 on the column 100. Specifically, the horizontal body 210 is slidably matched with the top surface 101 of the column 100, and the vertical body 220 is slidably matched with the front side surface 102 of the column 100. When the horizontal body 210 is separated from the vertical body 220, the adjustment assembly 500 is connected to the vertical body 220 to adjust the parallelism between the slide body 200 and the column 100 in the vertical direction, and the limiter 600 is connected to the horizontal body 210 to adjust the parallelism between the slide body 200 and the column 100 in the horizontal direction. It can be understood that when the horizontal body 210 and the vertical body 220 are combined together, the adjustment assembly 500 does not adjust the parallelism between the skateboard body 200 and the column 100 in the vertical direction alone, but the adjustment assembly 500 adjusts the parallelism between the entire skateboard body 200 and the column 100. Similarly, when the horizontal body 210 and the vertical body 220 are combined together, the stopper 600 does not adjust the parallelism between the skateboard body 200 and the column 100 in the horizontal direction alone, but the stopper 600 adjusts the parallelism between the entire skateboard body 200 and the column 100. In other words, the skateboard body 200 adjusts its parallelism with the column 100 through the joint action of the adjustment assembly 500 and the stopper 600.

[0054] In order to facilitate the installation of the first slider 310, an open groove 201 is provided on the side of the slider body 200, and the limiter 600 faces the outside of the open groove 201. The first slider 310 is arranged in the open groove 201. The two sides of the first slider 310 are respectively in contact with the limiter 600 and the inner side wall of the open groove 201. The limiter 600 is fixed to the column 100 near the open groove 201 by bolts, so that the limiter 600 can be fixed to the column 100. In addition, the abutment force between the limit member 600 and the first slider 310 can be adjusted by adjusting the locking force of the bolt. When the bolt and the limit member 600 are tightened, the abutment force between the limit member 600 and the first slider 310 will be increased, so that the first slider 310 can be more stably fixed in the opening groove 201, thereby improving the stability of the connection between the first slider 310 and the column 100, preventing the slide plate body 200 from tilting relative to the column 100, and improving the machining accuracy and repeated machining accuracy of the machine tool.

[0055] The above-mentioned machine tool body, the column 100 includes a top surface 101 and a front side surface 102 connected to each other, the guide rail mounting portion 110 includes a first guide rail mounting portion 111 located on the top surface 101 of the column 100, a second guide rail mounting portion 112 and a third guide rail mounting portion 113 located on the front side surface 102 and spaced from each other, the guide rail assembly 400 includes a first guide rail 410, a second guide rail 420 and a third guide rail 430 respectively arranged on the first guide rail mounting portion 111, the second guide rail mounting portion 112 and the third guide rail mounting portion 113, and the slider assembly 300 is slidably arranged on the first guide rail 410, the second guide rail 420 and the third guide rail 430; The adjustment component 500 is arranged between the slider component 300 and the skateboard body 200, and the adjustment component 500 is used to adjust the parallelism between the skateboard body 200 and the column 100 in the vertical and / or horizontal direction; when the skateboard body 200 is installed on the column 100 through three guide rails, the offset of gravity will cause the skateboard body 200 to naturally tilt forward relative to the column 100. By setting the adjustment component 500, the force of the skateboard body 200 tilting forward relative to the column 100 caused by the gravity offset of the skateboard body 200 can be offset, thereby improving the parallelism between the skateboard body 200 and the column 100, and ensuring that the three guide rails between the skateboard body 200 and the column 100 are balanced in force.

[0056] On the other hand, the present invention provides a machine tool, including a spindle box and the above-mentioned machine tool body, wherein the machine tool body also includes a base, the column 100 is arranged on the base, and the spindle box is slidably arranged on a side of the slide body 200 away from the column 100.

[0057] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0058] The above examples are only preferred embodiments of the present invention, and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
