Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a machine tool body and a machine tool. Background Technology

[0002] In CNC machine tool applications, the effectiveness of protecting critical moving parts such as lead screws and linear guides is a crucial factor affecting the machine's accuracy and stability. Bellows covers are a commonly used form of protection, with gaps at the bottom of the cover compared to other sheet metal structures, creating air passages.

[0003] During machine tool processing, tiny impurities can enter the protective enclosure directly through the air passage, contaminating precision components such as linear guides. This not only accelerates the damage to these precision components but also reduces the machining accuracy and lifespan of the machine tool (see patent CN216181757U for details).

[0004] Therefore, improving the protection of precision components in machine tools is an urgent problem to be solved. Utility Model Content

[0005] This utility model provides a machine tool body and machine tool, which can avoid impurities from contaminating the guide rails and lead screws and nuts, thereby improving the machining accuracy of the machine tool.

[0011] In some feasible embodiments, the end of the second shield away from the mounting plate has a bent guide portion, the bending direction of which is toward the top of the support portion.

[0012] In some feasible implementations, the first blocking member includes a first vertical plate, a second vertical plate, and a horizontal plate. The first vertical plate is fixedly connected to the crossbeam. One side of the horizontal plate is fixedly connected to the bottom of the first vertical plate. The other side of the horizontal plate extends to the bottom of the telescopic cover. The bottom of the second vertical plate is fixed to the middle of the horizontal plate. The second vertical plate extends upward. The first vertical plate, the second vertical plate, and the horizontal plate form an oil receiving groove structure.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] To provide a clearer and more accurate understanding of the present invention, a detailed description will now be provided in conjunction with the accompanying drawings. The accompanying drawings illustrate examples of embodiments of the present invention, wherein the same reference numerals denote the same elements. It is to be understood that the scale shown in the accompanying drawings is not the actual scale of the present invention, but is for illustrative purposes only and is not a drawing based on the original dimensions.

[0031] In the prior art, the telescopic guard is movable relative to the crossbeam. Although the telescopic guard can protect the guide rail assembly, there is no seal between the bottom of the telescopic guard and the crossbeam. There is a gap between the telescopic guard and the crossbeam. During machine tool processing, small diameter impurities can bypass the protection through the gap, contaminating the guide rail and even the lead screw and nut at a higher position, thereby accelerating the wear of the guide rail and the lead screw and nut and reducing the machining accuracy of the machine tool.

[0032] To address the issue of small-diameter impurities contaminating the guide rails and even the lead screw and nut through the gap between the telescopic cover and the crossbeam, please refer to... Figure 1 and 2 This application provides a machine tool body, including a crossbeam 100, a slide plate 200, a telescopic guard 300, a guide rail assembly 400, and a first blocking member 500. The slide plate 200 is slidably mounted on the front side of the crossbeam 100 via the guide rail assembly 400, and the sliding direction of the slide plate 200 is parallel to the extending direction of the crossbeam 100 (see reference). Figure 1 The telescopic cover 300 is mounted on the guide rail assembly 400 in a direction perpendicular to both the vertical and front-back directions. Both ends of the telescopic cover 300 are connected to the crossbeam 100 and the slide plate 200, respectively. The connection between the telescopic cover 300 and the slide plate 200 is a movable end, while the connection between the telescopic cover 300 and the crossbeam 100 is a fixed end. The first blocking member 500 is installed between the crossbeam 100 and the guide rail assembly 400. By setting the first blocking member 500, the gap T between the crossbeam 100 and the telescopic cover 300 can be initially reduced, improving the sealing performance between the crossbeam 100 and the telescopic cover 300.

[0033] Please refer to Figure 2 and 3The structure of the telescopic cover 300 and how the telescopic cover 300 forms a gap T with the crossbeam 100 and the first blocking member 500 are described below. The telescopic cover 300 includes a support part 310 located above the first blocking member 500. The support part 310 is provided with a sliding hole. The machine tool body also includes a guide rod. The guide rod is fixed relative to the crossbeam 100 and passes through the sliding hole of the support part 310. When the telescopic cover 300 moves, the support part 310 can be slidably supported on the guide rod, and the support part 310 can be folded and extended. The telescopic shield 300 also includes a main body 320 connected to the support part 310. The support part 310 is located below the rear part of the main body 320 facing the crossbeam 100, and the height of the bottom of the support part 310 is higher than the height of the bottom of the main body 320. That is, the main body 320 and the support part 310 are connected to the side away from the crossbeam 100, and the support part 310 and the main body 320 form a right-angle structure that matches the shape of the first blocking member 500, thereby forming at least two interconnected right-angle gaps T between the telescopic shield 300 and the first blocking member 500.

[0034] It is understood that the first blocking member 500, in addition to reducing the gap T, also collects waste oil generated during the operation of the guide rail assembly 400 and the lead screw and nut. Specifically, the first blocking member 500 includes a first vertical plate 510, a second vertical plate 520, and a horizontal plate 530. The height of the first vertical plate 510 is higher than the height of the support part 310, and the first vertical plate 510 is spaced apart from the telescopic cover 300 along the front-rear direction. The first vertical plate 510 is fixedly connected to the crossbeam 100. For example, the bottom of the front side of the first vertical plate 510 and the crossbeam 100 are stacked along the front-rear direction. One side of the horizontal plate 530 is fixedly connected to the bottom of the first vertical plate 510. The horizontal plate 530 is set at a right angle to the first vertical plate 510. The other side of the horizontal plate 530 extends to the bottom of the telescopic cover 300. That is, the height of the horizontal plate 530 is lower than the bottom height of the telescopic cover 300, and the vertical projection of the horizontal plate 530 overlaps with the main body 320. Specifically, the length of the support part 310 in the front-to-back direction is half the length of the horizontal plate 530 in the front-to-back direction, and the length of the horizontal plate 530 that overlaps with the main body 320 in the vertical direction is 1 / 3 of the total length of the horizontal plate 530. This ensures that only impurities that move from front to back between the horizontal plate 530 and the telescopic cover 300 can enter the gap T, blocking impurities that move in other directions.

[0035] Please refer to Figure 3The bottom of the second vertical plate 520 is fixed to the middle of the horizontal plate 530. The second vertical plate 520 extends upward. The first vertical plate 510, the second vertical plate 520 and the horizontal plate 530 form an oil receiving groove structure 501. The oil receiving groove structure 501 can not only receive the waste oil falling from the guide rail assembly 400 and the lead screw nut, but also receive the small impurities that "climb" from the gap T between the first blocking member 500 and the telescopic cover 300 to the top of the second vertical plate 520.

[0036] Please refer to Figure 3 To further reduce the gap T between the first blocking member 500 and the telescopic cover 300, the machine tool body also includes a second blocking member 600. The second blocking member 600 is disposed in the gap T between the first blocking member 500 and the telescopic cover 300, or the second blocking member 600 is disposed in the gap T between the crossbeam 100 and the telescopic cover 300. The opening direction of the oil receiving groove structure 501 faces the gap T, so that the oil receiving groove can also collect and store impurities that move through the gap T.

[0037] By setting a second blocking member 600, this application can further reduce the gap T between the first blocking member 500 and the telescopic cover 300, improve the sealing between the first blocking member 500 and the telescopic cover 300, thereby preventing small external impurities from bypassing the protection of the telescopic cover 300 through the gap T between the crossbeam 100 and the telescopic cover 300, preventing small external impurities from contacting the guide rail and the lead screw nut, preventing impurities from contaminating the guide rail and the lead screw nut, and improving the machining accuracy of the machine tool.

[0038] It is understood that the specific positions of the first blocking member 500 and the second blocking member 600 are not limited, as long as they are set between the crossbeam 100 and the telescopic cover 300, for example, at the front end, middle end, or rear end of the gap T between the crossbeam 100 and the telescopic cover 300. The specific number of the first blocking member 500 and the second blocking member 600 is not limited, but the number of the first blocking member 500 and the second blocking member 600 is at least one.

[0039] It is understandable that by setting the first blocking member 500 and the second blocking member 600, both of which are located in the gap T between the crossbeam 100 and the telescopic shield 300, the gap T between the crossbeam 100 and the telescopic shield 300 can be reduced through the double structure. This prevents external cutting fluid, chips and other impurities from bypassing the protection of the telescopic shield 300, and prevents cutting fluid, chips and other impurities from contaminating the guide rail assembly 400 or even damaging the guide rail assembly 400 and other precision structural components.

[0040] Please refer to Figure 3 and 4The detailed structure of the second blocking member 600 is described below. The second blocking member 600 includes a mounting plate 610 and a first shielding plate 620 connected to each other. The mounting plate 610 is detachably connected to the first blocking member 500, and the first shielding plate 620 extends towards the telescopic cover 300. The mounting plate 610 can be vertical, and the first shielding plate 620 is perpendicular to the mounting plate 610, thereby facilitating the fixing of the mounting plate 610 and the first blocking member 500 to the crossbeam 100 in the front-back direction. The first shielding plate 620 can be horizontal (i.e.,...). Figure 1 The first baffle plate 620 is positioned within the gap T in the front-back direction, thereby reducing the width of the gap T. The first baffle plate 620 can block small-diameter chips and cutting fluid, further limiting the contamination of the guide rail assembly 400 by small-diameter chips and cutting fluid.

[0041] To make the arrangement of the first shielding plate 620 more flexible and adaptable to various usage scenarios, the first shielding plate 620 is connected to the bottom of the mounting plate 610. The first shielding plate 620 can also be inclined. Specifically, the first shielding plate 620 is set at an obtuse angle to the mounting plate 610, that is, the height of the end of the first shielding plate 620 away from the mounting plate 610 is lower than the height of the other end of the first shielding plate 620 close to the mounting plate 610.

[0042] Please refer to Figure 4 To enable the second blocking member 600 to have a double-layer blocking structure and improve its effectiveness in blocking small-diameter chips and cutting fluid, the second blocking member 600 further includes a second baffle plate 630. The first baffle plate 620 is disposed opposite to the support portion 310, and the second baffle plate 630 is connected to the top of the mounting plate 610 and located between the support portion 310 and the guide rail assembly 400. At least a portion of the structure of the second baffle plate 630 blocks the gap T, and the protruding end of the second baffle plate 630 extends above the support portion 310. The second baffle plate 630 is disposed at an acute angle to the mounting plate 610 or perpendicular to each other, so that small-diameter chips and cutting fluid entering the gap T are blocked by the first baffle plate 620 and the second baffle plate 630 in sequence, thereby improving the protective effect of the second blocking member 600.

[0043] The structure of the second baffle plate 630 extending away from the mounting plate 610 extends above the telescopic shield 300, thereby enabling the second baffle plate 630 to form a reflux structure with the mounting plate 610 and the telescopic shield 300. When small-diameter chips and cutting fluid reach the second baffle plate 630, they will be intercepted by the second baffle plate 630 and then fall back into the gap T and be discharged, or fall onto the top of the support portion 310 of the telescopic shield 300 and then flow back into the gap T and be discharged.

[0044] Please refer to Figure 4 To guide impurities reaching the second baffle 630 back out more quickly, the end of the second baffle 630 away from the mounting plate 610 has a bent guide portion 631, the bending direction of which is towards the top of the support portion 310. By providing the bent guide portion 631, smaller diameter chips and cutting fluid reaching the second baffle 630 can be guided back to the top of the support portion 310 and discharged through the gap T.

[0045] To improve the flexibility of installing the second blocking member 600 and facilitate adjustment of its installation position, the machine tool body also includes fasteners. The mounting plate 610 is provided with an adjustment hole 611 extending along the height direction of the mounting plate 610. The crossbeam 100 is provided with a mating hole. The fastener is locked into the adjustment hole 611 and the mating hole. In this embodiment, the adjustment hole 611 is an oblong hole, allowing the fastener to lock into different positions, adjusting the vertical height of the mounting plate 610 relative to the crossbeam 100, thereby adjusting the position of the second blocking member 600 relative to the crossbeam 100.

[0046] Please refer to Figure 4 In order to facilitate the pre-installation of the second blocking member 600 and improve the installation efficiency of the second blocking member 600, the first shielding plate 620 is provided with a clearance groove 621 communicating with the adjustment hole 611. The clearance groove 621 penetrates the first shielding plate 620 in the front-back direction. Because the first shielding plate 620 is provided with a clearance groove 621, when pre-installing the second blocking member 600, the fastener is first threaded into the mating hole (i.e., the threaded hole) of the crossbeam 100, and there is a gap between the fastener and the crossbeam 100. Then, the second blocking member 600 passes through the clearance groove 621 from top to bottom through the fastener, realizing the quick assembly of the fastener and the adjustment hole 611. Compared with the existing method of first passing the fastener through the adjustment hole 611 and then installing it onto the threaded hole of the crossbeam 100, the existing method will block the view of the threaded hole on the crossbeam 100 by the mounting plate 610, thus taking more installation time. This application can pass the clearance groove 621 through the fastener while the staff can observe it, and the assembly can be successful in one go, saving installation time.

[0047] In some other embodiments, the second blocking member 600 is integrally formed with the first blocking member 500, thereby enabling the first blocking member 500 and the second blocking member 600 to be installed onto the crossbeam 100 in a single operation, simplifying the installation process and reducing installation time. For example, the second blocking member 600 is plate-shaped and integrally formed with the first blocking member 500. The second shielding plate 630 can be formed by bending the first vertical plate 510 toward the telescopic cover 300. As for the formation of the first shielding plate 620, the position of the first shielding plate 620 can be added within the mold for manufacturing the first vertical plate 510, so that the first vertical plate 510 and the first shielding plate 620 are integrally formed, and the mounting plate 610 structural component is also omitted.

[0048] The machine tool body includes a crossbeam 100, a slide plate 200, a telescopic cover 300, a guide rail assembly 400, and a first blocking member 500. The slide plate 200 is slidably mounted on the front side of the crossbeam 100 via the guide rail assembly 400, and the sliding direction of the slide plate 200 is parallel to the extension direction of the crossbeam 100. The telescopic cover 300 covers the guide rail assembly 400, and both ends of the telescopic cover 300 are respectively connected to the crossbeam 100 and the slide plate 200. The first blocking member 500 is installed between the crossbeam 100 and the guide rail assembly 400. The machine tool body also includes a second blocking member 600, which is disposed in the gap T between the first blocking member 500 and the telescopic cover 300, or the second blocking member 600 is disposed in the gap T between the crossbeam 100 and the telescopic cover 300.

[0049] By setting the first blocking member 500, the gap T between the crossbeam 100 and the telescopic cover 300 can be initially reduced, improving the sealing performance between the crossbeam 100 and the telescopic cover 300. By setting the second blocking member 600, the gap T between the first blocking member 500 and the telescopic cover 300 can be further reduced, improving the sealing performance between the first blocking member 500 and the telescopic cover 300. This prevents small external impurities from contacting the guide rail and lead screw nut through the gap T between the crossbeam 100 and the telescopic cover 300, avoiding contamination of the guide rail and lead screw nut, and improving the machining accuracy of the machine tool.

[0050] This application also provides a machine tool, including a base 800, a column 700 and an outer sheet metal guard 900. The column 700 is connected to the base 800, and the outer sheet metal guard 900 is connected to the base 800. It also includes the aforementioned machine tool body. The crossbeam 100 is connected above the column 700. The telescopic guard 300 is also connected to the outer sheet metal guard 900. A spindle 1000 is connected to the slide plate 200.

[0051] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.

[0052] The above-listed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
