Description

Technical Field

[0001] This application relates to the field of machine tool technology, and more specifically, to a machining center. Background Technology

[0002] Existing machining centers typically consist of a base, worktable, support, crossbeam, and milling assembly. The crossbeam is usually manufactured using a casting process, and then the base, worktable, support, crossbeam, and milling assembly are assembled. This results in an excessively heavy overall weight for the machining center, making it inconvenient to transport. Utility Model Content

[0003] The main objective of this application is to provide a machining center that at least solves the problem of excessive overall weight of machining centers in the prior art.

[0004] According to one aspect of this application, a processing center is provided, comprising:

[0005] Base;

[0006] A workbench, which is disposed on the base;

[0007] Support portions are provided on both sides of the base in the width direction;

[0008] A crossbeam is disposed on the support portion. The crossbeam includes an outer cover and a first partition. A first installation space is provided inside the outer cover. The first partition includes multiple partitions, which are spaced apart in the first installation space along the extension direction of the crossbeam.

[0009] Each of the first partitions and the outer cover is connected by welding.

[0010] Furthermore, the outer cover includes:

[0011] A base plate, which is connected to the support portion;

[0012] A first side plate is connected to the top of the bottom plate and is located on the first side of the extension direction of the crossbeam.

[0013] The second side plate is connected to the top of the bottom plate and is located on the second side of the extension direction of the crossbeam;

[0014] A top plate, which is connected to the first side plate and the second side plate and is located on the side opposite to the bottom plate;

[0015] In this configuration, along the direction from the first side plate to the second side plate, each of the first partition plates is spaced apart between the first side plate and the second side plate.

[0016] Furthermore, the outer cover also includes a first panel and a second panel, the first panel being connected to a first side of the base plate along the extension direction of the base, and the second panel being connected to a second side of the base plate along the extension direction of the base.

[0017] The base plate, the top plate, the first side plate, the second side plate, the first panel, and the second panel are connected end to end and enclose the first installation space. The base plate is welded to the first side plate, the second side plate, the first panel, and the second panel. The top plate is welded to the first side plate, the second side plate, the first panel, and the second panel. The first panel and the second panel are both welded between the first side plate and the second side plate.

[0018] Furthermore, the support includes two columns, which are respectively disposed on both sides of the base in the width direction, and the crossbeam is connected to the top of the two columns;

[0019] The column includes a third panel connected to the second panel, and the third panels of the two columns are integrally formed with the second panel.

[0020] Furthermore, along the extension direction of the base, the column also includes a fourth panel disposed opposite to the third panel. Along the width direction of the base, the column also includes a third side plate and a fourth side plate. The third panel, the third side plate, the fourth panel and the fourth side plate are connected end to end in sequence and enclose a second installation space. The third panel and the fourth panel are both welded between the third side plate and the fourth side plate.

[0021] The column also includes a plurality of second partitions, which are spaced apart along the height direction of the column and welded into the second installation space.

[0022] Furthermore, along the extending direction of the base, the column also includes a fourth panel disposed opposite to the third panel, the fourth panel having a first lifting hole; and / or,

[0023] A second hoisting hole is provided on the top plate.

[0024] Furthermore, a guide rail assembly is provided on the first panel, the guide rail assembly extending along the direction from the first side plate to the second side plate;

[0025] The machining center also includes a milling assembly, which is slidably mounted on the guide rail assembly.

[0026] Furthermore, the first panel includes a first straight segment, an inclined segment, and a second straight segment. The first straight segment is connected to the base plate and extends along the height direction of the machining center. The inclined segment is connected to the first straight segment and extends inclinedly in a direction close to the second panel. The second straight segment is connected between the inclined segment and the top plate.

[0027] The guide rail assembly includes a first guide rail and a second guide rail. The first guide rail is disposed on the first straight segment, and the second guide rail is disposed on the second straight segment. The milling assembly is slidably disposed on the first guide rail and the second guide rail.

[0028] Furthermore, the crossbeam also includes a reinforcing pipe disposed within the first installation space, and the reinforcing pipe extends through multiple first partitions along the extension direction of the crossbeam.

[0029] Furthermore, each of the first partitions is equally spaced, and the distance A between two adjacent first partitions satisfies the relationship: 415mm ≤ A ≤ 445mm; and / or,

[0030] The maximum height H1 of the support along the machining center and the maximum height H2 of the crossbeam along the machining center satisfy the following relationship: 1.5 ≤ H1 / H2 ≤ 1.7; and / or,

[0031] Along the extension direction of the beam, the length L of the beam and the maximum height H2 of the beam satisfy the following relationship: 0.28≤H2 / L≤0.32.

[0032] Unlike existing technologies, the crossbeam in this application includes an outer cover and multiple first partitions. A first installation space is provided within the outer cover, meaning the outer cover is hollow, which reduces the weight of the crossbeam to some extent. Furthermore, the multiple first partitions are spaced apart within the first installation space of the outer cover to provide support for the outer cover and improve the structural strength of the crossbeam. Additionally, each first partition is welded to the outer cover; that is, the crossbeam of this application is manufactured using a welding process. This eliminates the need for pre-casting molds for the crossbeam, thus reducing manufacturing costs. Furthermore, the welding process allows for the connection of multiple first partitions to the outer cover, resulting in more openwork structures on the crossbeam. It also eliminates the need to retain excess machining material on the crossbeam to avoid defects from the casting process, facilitating weight reduction and overall weight reduction, thus making it easier to transport to the machining center. In addition, compared with the existing casting process, the casting process requires heat treatment, cleaning, rust prevention, rough machining and fine machining of the beam. The welding process, on the other hand, involves heat treatment, welding and grinding. Compared with the casting process, the welding process is simpler, which reduces the manufacturing cost of the beam to a certain extent. Attached Figure Description

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0045] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0046] As mentioned in the background section, for example, the integrated gantry machining center disclosed in Chinese patent CN206029300U, in which the column 31 and the crossbeam 40 are both cast. Although the casting of the column 31 and the crossbeam 40 improves the assembly accuracy and machining accuracy of the machining center, the machining center is usually large, which means that the molds for manufacturing the cast crossbeam 40 and the column 31 also need to be very large, making the cost of casting the column 31 and the crossbeam too high. On the other hand, because the casting process needs to avoid defects such as shrinkage cavities and porosity in the workpiece during casting, it is necessary to add excess material to the workpiece, which makes the weight of the crossbeam 40 and the column 31 manufactured by the casting process too heavy. After the machining center is assembled, more manpower and resources are needed to transport the machining center to other places.

[0047] See Figures 1 to 7 As shown, according to an embodiment of this application, a machining center is provided, which includes a base 10, a worktable 20, a support 30, and a crossbeam 40.

[0048] The workbench 20 is mounted on the base 10, and the support 30 is located on both sides of the base 10 in the width direction (X direction in the attached figure). A crossbeam 40 is mounted on the support 30. The crossbeam 40 includes an outer cover 41 and first partitions 42. A first mounting space 410 is provided inside the outer cover 41. Multiple first partitions 42 are spaced apart within the first mounting space 410 along the extension direction of the crossbeam 40 (X direction in the attached figure). All first partitions 42 and the outer cover 41 are welded together.

[0049] Unlike existing technologies, in this embodiment, the crossbeam 40 includes an outer cover 41 and multiple first partitions 42. A first mounting space 410 is provided within the outer cover 41, meaning the outer cover 41 is hollow, which reduces the weight of the crossbeam 40 to some extent. Furthermore, the multiple first partitions 42 are spaced apart within the first mounting space 410 of the outer cover 41 to provide support for the outer cover 41 and improve the structural strength of the crossbeam 40. In addition, each first partition 42 is welded to the outer cover 41. That is, the crossbeam 40 in this embodiment is manufactured using a welding process. On the one hand, this eliminates the need to manufacture the molds required for casting the crossbeam 40 in the early stages, thus reducing manufacturing costs. On the other hand, the welding process connects the multiple first partitions 42 to the outer cover 41, resulting in more openwork structures on the crossbeam 40. It also eliminates the need to retain excess machining material on the crossbeam 40 to avoid defects caused by the casting process, facilitating weight reduction and overall weight reduction, thus making it easier to transport to the machining center. In addition, compared with the existing casting process, the casting process of the crossbeam 40 requires heat treatment, cleaning, rust prevention, rough machining and fine machining. The welding process is heat treatment, welding and grinding. Compared with the casting process, the welding process is simpler, which reduces the manufacturing cost of the crossbeam 40 to a certain extent.

[0050] Further, the outer cover 41 includes a base plate 411, a first side plate 413, a second side plate 414, and a top plate 412. The base plate 411 is connected to the support portion 30, the first side plate 413 is connected to the top of the base plate 411 and is located on a first side in the extension direction of the crossbeam 40, and the second side plate 414 is connected to the top of the base plate 411 and is located on a second side in the extension direction of the crossbeam 40. The top plate 412 is connected to the first side plate 413 and the second side plate 414 and is located on a side opposite to the base plate 411. Along the direction from the first side plate 413 to the second side plate 414, each first partition 42 is spaced apart between the first side plate 413 and the second side plate 414.

[0051] Specifically, in this embodiment, the support 30 is a column 31, and the base plate 411 is fixedly connected to the column 31. The first side plate 413 and the second side plate 414 are both connected between the top plate 412 and the base plate 411. The first side plate 413 and the second side plate 414 are used to provide support and protection for the base plate 411 and the top plate 412. Along the direction from the first side plate 413 to the second side plate 414, the first installation space is located in the space enclosed by the base plate 411, the top plate 412, the first side plate 413, and the second side plate 414. Each first partition 42 is spaced between the first side plate 413 and the second side plate 414, thereby improving the stability of the crossbeam 40. In the actual manufacturing of the crossbeam 40, the first side plate 413 and the second side plate 414 are first connected to the bottom plate 411. Then, multiple first partition plates 42 are welded between the first side plate 413 and the second side plate 414 at intervals. Finally, the top plate 412 is welded to the first side plate 413, the second side plate 414 and the multiple first partition plates 42.

[0052] In addition, the outer cover 41 also includes a first panel 415 and a second panel 416. The first panel 415 is connected to the first side of the base plate 411 along the extension direction of the base 10 (as shown in the Y direction in the figure), and the second panel 416 is connected to the second side of the base plate 411 along the extension direction of the base 10. The base plate 411, top plate 412, first side plate 413, second side plate 414, first panel 415, and second panel 416 are connected end to end and enclose a first installation space 410. The base plate 411 is welded to the first side plate 413, second side plate 414, first panel 415, and second panel 416. The top plate 412 is welded to the first side plate 413, second side plate 414, first panel 415, and second panel 416. The first panel 415 and the second panel 416 are both welded between the first side plate 413 and the second side plate 414.

[0053] It is understood that the first panel 415, the second panel 416, the first side panel 413, the second side panel 414, the top panel 412, and the bottom panel 411 are connected end to end to form a box structure, and the first installation space 410 is the inner cavity of the box structure. In this embodiment, each panel is connected to other panels by welding. That is to say, the crossbeam 40 is formed by welding multiple panels. Welding multiple panels facilitates the manufacture of large structures. At the same time, the overall weight of the crossbeam 40 can be controlled according to the number of welded panels. That is, when the overall rigidity of the crossbeam 40 is satisfied, a certain number of the first partitions 42 can be reduced, thereby reducing the overall weight of the crossbeam 40.

[0054] Furthermore, the support 30 includes two columns 31, which are respectively disposed on both sides of the base 10 in the width direction, and the crossbeam 40 is connected to the top of the two columns 31. The column 31 includes a third panel 312 connected to the second panel 416, and the third panel 312 of the two columns 31 is integrally formed with the second panel 416.

[0055] Specifically, the column 31 connects the crossbeam 40 and the base 10, and the column 31 provides support for the crossbeam 40. In this embodiment, unlike the prior art, the third panel 312 of the column 31 and the second panel 416 of the crossbeam 40 are integrally formed. This improves the structural stability between the column 31 and the crossbeam 40, as well as the assembly accuracy of the crossbeam 40 and the column 31. On the other hand, it avoids unnecessary connecting parts between the second panel 416 and the third panel 312, making the column 31 and the crossbeam 40 lighter overall, thus reducing the overall weight of the machining center.

[0056] Furthermore, along the extending direction of the base 10, the column 31 also includes a fourth panel 311 disposed opposite to the third panel 312. Along the width direction of the base 10, the column 31 also includes a third side plate 313 and a fourth side plate 314. The third panel 312, the third side plate 313, the fourth panel 311, and the fourth side plate 314 are connected end to end in sequence and enclose a second mounting space 310. The third panel 312 and the fourth panel 311 are both welded between the third side plate 313 and the fourth side plate 314. The column 31 also includes a plurality of second partitions 32, which are spaced apart along the height direction of the column 31 (as shown in the Z direction in the figure) and welded within the second mounting space 310.

[0057] In other words, the side of the third side plate 313, the fourth side plate 314, and the fourth panel 311 closest to the crossbeam 40 are all connected to the bottom plate 411 of the crossbeam 40. The third side plate 313, the fourth side plate 314, the third panel 312, and the fourth panel 311 form a ring structure, and the second installation space 310 is the cavity within the ring structure. In addition, in this embodiment, the column 31 also includes multiple second partitions 32, which are spaced apart along the height direction of the column 31 and welded into the second installation space 310, thereby improving the structural strength of the column 31. In practice, when installing the second partitions 32, the second partitions 32 need to be welded to the third panel 312, the fourth panel 311, the third side plate 313, and the fourth side plate 314 respectively. After the column 31 and the crossbeam 40 are welded together, the column 31 and the crossbeam 40 form an integral structure.

[0058] In some embodiments, the column 31 further includes a connecting plate, which is connected to the third side plate 313, the fourth side plate 314, the third panel 312 and the side of the third panel 312 near the base 10. The connecting plate has a connecting hole 315, and the connecting plate is connected to the base 10 by bolts passing through the connecting hole 315.

[0059] Furthermore, a first lifting hole 3111 is provided on the fourth panel 311. Optionally, a second lifting hole 4121 is provided on the top plate 412.

[0060] In practice, when moving the column 31 and the beam 40, the lifting parts of the handling equipment can be passed through the first lifting hole 3111 or the second lifting hole 4121, or both, to facilitate the transportation of the beam 40 and the column 31.

[0061] In some embodiments, weight reduction holes 60 are provided on the first side plate 413, the second side plate 414, the first partition 42, the second partition 32, the second panel 416, and the top plate 412. The weight reduction holes 60 are used to reduce the weight of the column 31 and the crossbeam 40, thereby reducing the overall weight of the machining center.

[0062] Furthermore, a guide rail assembly 43 is provided on the first panel 415, extending along the direction from the first side plate 413 to the second side plate 414. The machining center also includes a milling assembly (not shown in the figure), which is slidably mounted on the guide rail assembly 43.

[0063] In this embodiment, the milling assembly includes a saddle and a spindle box. The saddle is slidably mounted on the guide rail assembly 43. The spindle box is mounted on the side of the saddle away from the first panel 415. A slide rail is mounted on the side of the saddle near the spindle box. The slide rail extends along the height direction of the saddle. The milling assembly is slidably mounted on the slide rail. A milling head is mounted at the bottom of the spindle box for machining the workpiece.

[0064] Furthermore, the first panel 415 includes a first straight segment 4151, an inclined segment 4152, and a second straight segment 4153. The first straight segment 4151 is connected to the base plate 411 and extends along the height direction of the machining center. The inclined segment 4152 is connected to the first straight segment 4151 and extends inclinedly in a direction close to the second panel 416. The second straight segment 4153 connects the inclined segment 4152 and the top plate 412. The guide rail assembly 43 includes a first guide rail 432 and a second guide rail 431. The first guide rail 432 is disposed on the first straight segment 4151, and the second guide rail 431 is disposed on the second straight segment 4153. The milling assembly is slidably disposed on the first guide rail 432 and the second guide rail 431.

[0065] Specifically, the first straight segment 4151, the inclined segment 4152, and the second straight segment 4153 are sequentially welded together to form the first panel 415. In this embodiment, both the first straight segment 4151 and the second straight segment 4153 extend along the height direction of the machining center. The first guide rail 432 is disposed on the first straight segment 4151, and the second guide rail 431 is disposed on the second straight segment 4153. The saddle is slidably disposed on the first guide rail 432 and the second guide rail 431. It can be understood that the double guide rail arrangement in this embodiment facilitates the improvement of the saddle's movement accuracy, the improvement of the saddle's movement synchronization, the improvement of the load-bearing capacity of the crossbeam 40, and the reduction of the friction between the saddle and the crossbeam 40, thereby improving the service life of the crossbeam 40 and the saddle to a certain extent.

[0066] Since the crossbeam 40 is welded from the first side plate 413, the second side plate 414, the top plate 412, the bottom plate 411, the first panel 415, the second panel 416, and a plurality of first partitions 42, although the plurality of first partitions 42 enhance the structural strength of the crossbeam 40, the structural strength between the first partitions 42 is relatively low due to the gaps between them. Therefore, in this embodiment, as shown in the attached... Figure 1 and attached Figure 4 As shown, the crossbeam 40 also includes a reinforcing pipe 50, which is disposed within the first installation space 410 and passes through multiple first partitions 42 along the extension direction of the crossbeam 40.

[0067] Specifically, the reinforcing pipe 50 extends from the first side plate 413 to the second side plate 414 and passes through multiple first partitions 42 in sequence, thereby improving the structural strength between the reinforcing first partitions 42 of the crossbeam 40. Furthermore, in this embodiment, to reduce the overall weight of the crossbeam 40, a through hole is provided in the middle of the reinforcing pipe 50 to reduce its weight.

[0068] Furthermore, the first partitions 42 are evenly spaced, and the distance A between two adjacent first partitions 42 satisfies the relationship: 415mm ≤ A ≤ 445mm. When the distance A between two adjacent first partitions 42 satisfies the above relationship, the structural strength of the beam 40 is stable, and there is no need to set too many first partitions 42, thereby reducing the overall weight of the beam 40 to a certain extent. When A is less than 415mm, the distance between two adjacent first partitions 42 is reduced, so more first partitions 42 need to be set. Although this enhances the structural strength of the beam 40, it also increases the overall weight of the beam 40. When A is greater than 445mm, the distance between two adjacent first partitions 42 is too large, which leads to a reduction in the number of first partitions 42, thereby reducing the structural strength of the beam 40. In this embodiment, the value of A can be 415mm, 420mm, 425mm, 430mm, 435mm, 440mm, and 445mm.

[0069] Furthermore, the maximum height H1 of the support part 30 along the machining center and the maximum height H2 of the crossbeam 40 along the machining center satisfy the following relationship: 1.5≤H1 / H2≤1.7.

[0070] Specifically, the support 30 is a column 31. When H1 / H2 is less than 1.5, it may be due to two reasons: firstly, the height of the crossbeam 40 may be too high, increasing its weight and thus the overall weight of the machining center, making transportation inconvenient; secondly, the height of the column 31 may be too low, potentially causing interference between the crossbeam 40 and the workpiece on the worktable 20 if the workpiece is too tall. If H1 / H2 is greater than 1.7, it may be due to two reasons: firstly, the height of the column 31 may be too high, increasing the overall weight of the machining center; secondly, the height of the crossbeam 40 may be too low, reducing its load-bearing capacity. The values ​​of H1 / H2 can be 1.5, 1.55, 1.6, 1.65, and 1.7.

[0071] Furthermore, along the extension direction of the crossbeam 40, the length L of the crossbeam 40 and the maximum height H2 of the crossbeam 40 satisfy the following relationship: 0.28≤H2 / L≤0.32.

[0072] In this embodiment, when H2 / L is less than 0.28, the length L of the crossbeam 40 may be set too large, or the maximum height of the crossbeam 40 may be set too small. A larger length of the crossbeam 40 would result in an excessively wide overall width of the machining center, increasing its floor space. Conversely, a smaller height of the crossbeam 40 would result in a lower load-bearing capacity, making it difficult to support the milling components. When H2 / L is greater than 0.32, it could be due to either an excessively high height of the crossbeam 40 or a short length. An excessively high height would result in an excessively high overall height of the machining center, leading to low space utilization. A short length might prevent the milling components from moving to the corresponding machining position on the workpiece on the worktable 20 when moving on the crossbeam 40. The value of H2 / L can be 0.28, 0.29, 0.30, 0.31, or 0.32.

[0073] In addition, in some embodiments, the worktable 20 is also manufactured by welding to further reduce the overall size of the machining center.

[0074] Specifically, the workbench 20 is rectangular and includes a first plate 21, a second plate 22, a third plate 23, a fourth plate 24, a fifth plate 25, a sixth plate 26, and a third partition 202. The first plate 21 is connected to the upper surface of the base 10. The second plate 22 is opposite to the first plate 21 and located on top of the first plate 21. The second plate 22 is used to mount the workpiece to be processed. The third plate 23 and the fourth plate 24 extend along the extension direction of the base 10. The first plate 21 is positioned on opposite sides of the first plate 21, and the third plate 23 and the fourth plate 24 are welded between the first plate 21 and the second plate 22.

The multiple third partitions 202 are provided with reinforcing ribs 203 to provide the load-bearing capacity and structural strength of the workbench 20.

[0076] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0077] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0078] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
