Description

Technical Field

[0001] This utility model relates to the field of machine tools, and more specifically, to a machine bed and a machine tool. Background Technology

[0002] In existing technology, gantry columns typically have a sliding plate mounted on a crossbeam. This sliding plate can move along the X-axis (length direction) of the crossbeam. Guide rails are installed on the sliding plate, and the spindle box is mounted on these rails and can move along the Z-axis (vertical direction), thus enabling the spindle box to move along the X / Z axes on the crossbeam. However, this method, with guide rails on the crossbeam and the sliding plate moving along the X-axis, results in a large weight for the moving parts of the spindle box, leading to slow acceleration and speed of the sliding plate along the crossbeam, potentially causing machine vibration. A feasible approach is to only install the spindle box component moving along the Z-axis on the crossbeam. To ensure the distance from the spindle centerline to the crossbeam, the thickness of the sliding plate needs to be increased, or the length of the spindle box in the Y-axis direction needs to be increased. Increasing the thickness of the sliding plate or the length of the spindle box increases the load on the crossbeam.

[0003] Based on the above issues, how to reduce the load on the crossbeam while ensuring the distance between the spindle center and the crossbeam is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0036] The first aspect of this utility model provides a gantry structure, as referenced... Figure 1 and Figure 2 The system includes a gantry structure 1, a slide block 2, a slide block 3, and a spindle box assembly. The gantry structure 1 includes a first column 11, a second column 12, and a crossbeam 13, which is horizontally mounted on the first column 11 and the second column 12. The slide block 2 is mounted on the crossbeam 13 and protrudes horizontally along the length of the crossbeam 13 for mounting the spindle box assembly 4.

[0037] In the above-mentioned scheme, preferably, the columns (including the first column 11 and the second column 12) are internally equipped with a reinforcing rib structure, and the reinforcing ribs are arranged in an "X" shape. This reinforcing rib structure can effectively improve the bending strength and torsional stiffness of the columns and reduce deformation caused by stress during operation. The crossbeam 13 is a cuboid structure, and its length is designed according to the spacing between the first column 11 and the second column 12 and the installation requirements. The crossbeam 13 and the columns can be integrally set. In addition, both ends of the crossbeam 13 can also be connected to the top of the first column 11 and the second column 12 respectively by high-strength bolts; the connection adopts a transition fit, and high-strength thread-locking agent is applied to the connection surface to ensure the firmness and reliability of the connection and prevent loosening during operation. The sliding plate seats 2 can be evenly arranged along the length direction (X-axis direction) of the crossbeam 13. Each sliding plate seat 2 is horizontally (Y-axis direction) protruding along the direction perpendicular to the length of the crossbeam, and the protrusion height can be set according to actual needs. The upper surface of the slide base 2 is provided with multiple threaded holes for mounting the spindle box component 4. The specifications of the threaded holes are designed according to the installation requirements of the spindle box component 4 to ensure that the spindle box component 4 can be accurately and stably mounted on the slide base 2.

[0038] This application provides a slide plate seat 2 on the crossbeam 13. The slide plate seat 2 protrudes horizontally along the length direction perpendicular to the crossbeam 13 and is used to mount the spindle box component 4. In actual use, the spindle box component 4 is securely mounted on the slide plate seat 2. The thickness of the slide plate seat 2 in the length direction perpendicular to the crossbeam 13 ensures that the distance between the spindle centerlines of the spindle box component meets the requirements, without increasing the length of the slide plate 3 or the spindle box 401, effectively avoiding the problem of increasing the load on the crossbeam 13.

[0039] In one specific implementation, reference is made to Figure 1 and Figure 2The slide block 2 comprises multiple sets, and the slide plates 3 and spindle box components 4 comprise multiple sets that are fitted together. The slide blocks 2, slide plates 3, and spindle box components 4 are installed in a one-to-one correspondence, meaning that each set of slide blocks 2 has one slide plate 3 installed, and each slide plate 3 has one spindle box component 4 installed, enabling multiple machine heads to be mounted on the gantry structure 1 for processing. The slide block 2 includes first mounting blocks 21 and second mounting blocks 22 spaced apart along the length of the crossbeam 13. In actual use, the two sides of the slide plate 3 can be correspondingly mounted on the first mounting blocks 21 and second mounting blocks 22. The first mounting blocks 21 and second mounting blocks 22 provide support to the two sides of the slide plate 3, making the installation of the slide plate 3 more balanced and stable. Through the reasonable layout and structural optimization of the first mounting blocks 21 and second mounting blocks 22, the flexibility and precision of the spindle box component 4 installation are improved, ensuring the reliability and stability of the machine tool during high-speed, high-precision machining.

[0040] Further, refer to Figure 1 and Figure 2 The first mounting block 21 includes a first sub-plate 23 and a second sub-plate 24 arranged at intervals between the upper and lower parts, and the second mounting block 22 includes a third sub-plate 25 and a fourth sub-plate 26 arranged at intervals between the upper and lower parts, so that each slide seat 2 includes four sub-plates. The slide 3 for mounting the spindle box component 4 is mounted on the four sub-plates to provide more stable and more balanced support for the slide 3.

[0041] In one specific embodiment, at least two skateboard seats 2 are provided, with adjacent skateboard seats 2 tightly fitted together or integrally formed, to save space on the crossbeam 13. For example, Figure 3 As shown, the four skateboard seats 2 are fitted together tightly, or four closely connected skateboard seats 2 are distributed on a single piece of structure. Alternatively, they can be configured as follows: Figure 2 As shown, in two adjacent sets of skateboard seats 2, the first mounting seat 21 and the second mounting seat 22 are tightly fitted together or integrally formed; the skateboard seat 2 and the crossbeam 13 are integrally formed. When the skateboard seat 2 is configured with four sub-plates, the adjacent sub-plates are tightly fitted together to save space between the skateboard seats 2. Figure 2 The four sub-modules layout scheme is relative to Figure 3 In the proposed design, the deformation of the crossbeam 13 under stress is reduced, and the weight of the crossbeam 13 is also reduced.

[0042] In one specific implementation, reference is made to Figure 2 and Figure 4 The slide plate 3 is provided with a mounting block 31 that matches the slide plate seat 2. The mounting block 31 is provided with a support block 32. When the slide plate 3 is connected to the slide plate seat 2, the support block 32 is pressed against the upper end surface of the slide plate seat 2. During the assembly of the slide plate 2 and the slide plate seat 3, the support block 32 provides support for the slide plate 3, making it easier for the slide plate 3 to be installed on the slide plate seat 2.

[0043] In one specific implementation, reference is made to Figure 1 and Figure 4 The bed also includes a first shim (not shown in the figure), which is disposed between the mounting block 31 and the slide seat 2. By adjusting the thickness or number of the first shims, the distance between the spindle centerline of the spindle box component 4 and the slide seat 2 can be adjusted. For example, by placing multiple stacked first shims between the mounting block 31 and the slide seat 2, the distance between the spindle centerline of the spindle box component 4 and the crossbeam 13 can be increased.

[0044] In one specific implementation, reference is made to Figure 1 , Figure 4 and Figure 5 The spindle box component 4 includes a spindle box 401 and a slider 402. A connecting part 403 is provided on the spindle box 401, and the connecting part 403 is connected to the slider 402. A slide rail 33 is provided on the side of the slide plate 3 away from the slide plate seat 2, and the slider 402 is slidably mounted on the slide rail 33.

[0045] An adjustment hole 404 extending along the length of the crossbeam 13 is provided on the side of the connecting part 403. An adjustment screw (not shown in the figure) is inserted into the adjustment hole 404. The adjustment screw abuts against the slide rail 33. The slide rail 33 can be pushed by the adjustment screw (for example, the adjustment screw is screwed into the adjustment hole 404) so ​​as to realize the fine adjustment of the spacing of the spindle box 401 in the length of the crossbeam 13 and ensure the spacing accuracy of the multi-head machine.

[0046] In one specific implementation, reference is made to Figure 1 , Figure 4 and Figure 5 The slide plate 3 is provided with two slide rails 33, and each slide rail 33 is provided with at least one slider 402; the back of the spindle box 401 is provided with a connecting part 403 that matches the slider 402, and the two vertical sides of the connecting part 403 are clamped on the slider 402. By providing slide rails 33 on both the left and right sides of the slide plate 3, the spindle box 401 is more stably and balancedly mounted on the slide plate 3.

[0047] In one specific implementation, reference is made to Figure 4 and Figure 5 The spindle box component 4 also includes a second shim 405. The slider 402 is mounted on the slide rail 33, and the spindle box 401 is mounted on the slider 402. The second shim 405 is disposed between the connecting part 403 and the slider 402. By adjusting the thickness and number of the second shims 405, the spacing of the spindle box 401 in the horizontal direction perpendicular to the length of the crossbeam 13 can be finely adjusted. For example, increasing the number of second shims 405 increases the spacing between the spindle box 401 and the slider 402.

[0048] This application, through the setting of adjusting pins and second shims 405, facilitates the adjustment of the positional accuracy of the spindle box 401 in the length direction (X-axis direction) and perpendicular to the length direction of the crossbeam 13 (Y-axis direction). Furthermore, this application provides four slide seats 2. During assembly, since the Z-axis of the four slide seats 3 is independent, the displacement of each slide seat 3 in the Z-axis direction can be adjusted individually, thereby achieving adjustment of the displacement of a single spindle box 403 in the X, Y, and Z-axis directions.

[0049] A second aspect of the present invention provides a machine tool, as shown in the reference. Figure 1 , Figure 4 and Figure 6 The machine tool includes a base 100, a worktable 200, and a tool magazine 300. The worktable 200 and the tool magazine 300 are mounted on the base 100. The machine tool also includes a bed of any of the above-mentioned types. The gantry structure 1 of the bed is set on the base 100. The worktable 200 and the tool magazine 300 are distributed on both sides of the gantry structure 1. The worktable 200 is set on the base 100 and can move laterally and longitudinally in the horizontal direction.

[0050] The spindle box component 4 includes a spindle box 401 and a spindle mounted on the spindle box 401. In the prior art, when the distance from the centerline of the spindle to the crossbeam 13 is fixed, if there is no protruding slide seat 2 on the crossbeam 13, it is necessary to either increase the thickness of the slide 3 or increase the length of the spindle box 401 to meet the distance requirement from the centerline of the spindle to the crossbeam 13. Increasing the thickness of the slide 3 increases its weight, which in turn increases the load on the crossbeam 13, leading to greater deformation and decreased rigidity of the crossbeam 13 under stress. Increasing the length of the spindle box 401 increases the distance from the centerline of the spindle to the crossbeam 13, which affects the rigidity and natural frequency of the spindle box 401. This application provides several slide seats 2 protruding from the crossbeam 13. The machine tool fixes the spindle box component 4 to the slide seats 2, thus meeting the distance requirement from the centerline of the spindle to the crossbeam 13 while avoiding the need to increase the thickness of the slide 3 or the length of the spindle box 401.

[0051] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
