Description

Technical Field

[0001] The present invention relates to the field of machine tools, in particular to a CNC machining machine tool capable of being spliced ​​and connected. Background Art

[0002] CNC machine tools are common mechanical equipment in mechanical processing. Due to the length of the CNC machine tools themselves, the length of the workpieces that can be processed by CNC machine tools is limited to a maximum value. Therefore, if you encounter a large workpiece, you need a corresponding large CNC machine tool to process it. The factory needs to purchase the corresponding machine tool production line, which is too costly. In addition, since large machine tools cannot be formed in one piece in the existing technology, a splicing process is generally required to assemble several modules into a complete CNC machine tool. Based on this, the following concept is proposed in the existing technology: multiple machine tool units can be spliced ​​in series to form a large machine tool to perform CNC processing on large workpieces; refer to the attached Figure 1 With attached Figure 2 , which is to splice two machine tool units into one, but this method has some shortcomings. For example, it simply uses fasteners to achieve serial splicing between multiple machine tool units. Since the processing system of the machine tool unit has its movement distance limit, when processing large workpieces, the part located at the connection between the two machine tool units cannot be processed by any machine tool unit processing system, and CNC processing has limitations.

[0003] Based on the above, the present invention proposes a CNC machine tool that can be spliced ​​and connected. Summary of the Invention

[0004] In order to solve the problems mentioned in the above background, the present invention provides a CNC machining machine tool that can be spliced ​​and connected.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows.

[0006] A CNC machining tool that can be spliced ​​and connected includes a base and multiple machine tool units mounted side by side on the base, a bed frame and a workbench of the machine tool units, and a moving assembly provided at the bottom of the machine tool units. The moving assembly is used to drive the machine tool units to move so that two adjacent machine tool units fit together, and then a fastener is used to achieve a fixed connection between the two machine tool units;

[0007] The bed frame of each machine tool unit is provided with a linear rail, the extension direction of the linear rail is parallel to the length direction of the bed frame, a slide is slidably installed on the linear rail, and the slide is fixed to the bottom of the workbench. The bed frame is also provided with a linear module for driving the workbench to move along the length direction.

[0008] As a further improvement and optimization of the present invention, a plurality of slides are arranged in an array on each linear rail, and there is a distance between the slides on the two most sides of the plurality of slides on the linear rail and the two ends of the linear rail;

[0009] The bottom of the workbench is provided with two supporting components close to both ends respectively, and the supporting components form rolling contact cooperation with the linear rail.

[0010] As a further improvement and optimization of the present invention, the supporting assembly includes a supporting seat fixedly connected to the workbench, and a rotating rod is installed at the bottom of the supporting seat. The axis of the rotating rod is parallel to the width direction of the workbench and the rotating rod can rotate around the axis. The lowest point of the outer cylindrical surface of the rotating rod is lower than the lower surface of the supporting seat, and the rotating rod contacts the linear rail and forms a rolling fit.

[0011] As a further improvement and optimization of the present invention, a plurality of rotating rollers are arranged in an array along the length direction of the workbench.

[0012] As a further improvement and optimization of the present invention, a hydraulic foot is provided at each of the four corners of the bed frame. During normal use, the hydraulic feet support the machine tool unit.

[0013] As a further improvement and optimization of the present invention, two slide rails are provided on the base, the extension direction of the slide rails is parallel to the length direction of the machine tool unit, the two slide rails are arranged side by side, and a rack is provided on each side of the two slide rails facing each other, and the rack and the slide rails are parallel to each other. The moving assembly includes two rolling parts arranged at the bottom of the bed frame, and the two rolling parts are respectively located at both ends of the bed frame.

[0014] As a further improvement and optimization of the present invention, the rolling component includes a roller whose axis is parallel to the width direction of the machine tool unit and is supported by a slide rail. A gear is provided at the end of the roller, and the gear is engaged with the rack.

[0015] As a further improvement and optimization of the present invention, a drive motor for driving the roller to rotate is provided on the bed frame, and a worm gear is included in the power transmission route between the roller and the drive motor.

[0016] As a further improvement and optimization of the present invention, an inclined surface is provided on the opposite side of the two slide rails, and the distance between the two inclined surfaces decreases along the vertical direction from bottom to top. A limiting boss is respectively provided on the opposite side of the two rollers of the rolling component, and the limiting boss is in the shape of a truncated cone and the outer cylindrical surface of the limiting boss is in contact with the corresponding inclined surface.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This solution adopts a modular design, with several machine tool units that can be moved, connected in series, and assembled into a large machine tool. It can be used to process large workpieces. This design allows the machine tool to quickly adjust its size and function according to specific processing requirements, effectively improving production efficiency and reducing costs, thereby improving the user's production benefits and market competitiveness. On this basis:

[0019] 1. An inclined surface is provided on the opposite side of the two slide rails, and the distance between the two inclined surfaces decreases vertically from bottom to top. A limiting boss is provided on the opposite side of the two rollers of the rolling component, and the limiting boss is in the shape of a truncated cone, and the outer cylindrical surface of the limiting boss is in contact with the corresponding inclined surface. Its significance lies in that, during normal use, the support of the machine tool unit is achieved by the hydraulic foot. Therefore, there is a slight gap between the roller and the slide rail, or it is just a simple contact, which does not play a supporting role, so as to avoid damage to the moving component. When movement is required, the hydraulic foot retracts, and under the action of gravity, the machine tool unit has a downward trend. Under the cooperation of the outer cylindrical surface of the limiting boss and the corresponding inclined surface, it can play a self-positioning role, so that the two adjacent machine tool units can be accurately aligned.

[0020] Second, after the machine tool units are assembled, when processing large workpieces, the linear module can be used to drive the worktable to move, thereby moving the large workpiece clamped on the worktable together. Therefore, any part of the large workpiece can be CNC-machined, solving the problem mentioned in the background art that "the CNC machining of the part of the large workpiece located at the connection between the two machine tool units has limitations."

[0021] On this basis, two supporting components are provided at the bottom of the workbench, one close to the two ends. In this way, at the beginning, the two ends of the workbench are supported by the two supporting components. When the workbench needs to move subsequently, the supporting components are rolled together with the linear rail through a rotating rod, unlike the sliding connection between the slide and the linear rail. Therefore, the rotating rod can roll from one linear rail to another, thus taking into account the supporting effect of the workbench and not interfering with the moving accuracy of the workbench, and not affecting the CNC machining of large workpieces.

[0036] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0037] This plan is attached Figure 11 With attached Figure 12 In FIG. 1 , a refers to the contact position of the linear rails 108 on the two work tables 101 after the two machine tool units 100 are assembled, which is indicated by a thick line.

[0038] Reference Figure 3-Figure 12A CNC machining center that can be spliced ​​and connected includes a base 200 and multiple machine tool units 100 installed side by side on the base 200, a bed frame, a workbench 101 and a machining system of the machine tool units 100, etc. These are all achievable with existing technologies and will not be described in detail.

[0039] In this solution, two machine tool units 100 are taken as an example for explanation.

[0040] A moving assembly is provided at the bottom of the machine tool unit 100 , and the moving assembly is used to drive the machine tool unit 100 to move, so that two adjacent machine tool units 100 can be fitted together.

[0041] Specifically, refer to Figure 6-Figure 8 A hydraulic foot 102 is provided at each of the four corners of the bed frame. The hydraulic foot 102 can be realized by using existing hydraulic technology and will not be elaborated on. It can apply an upward lifting force to the bed frame. During normal use, the machine tool unit 100 is supported by the hydraulic foot 102. Because the machine tool unit 100 is heavy, it is necessary to prevent the moving components from being subjected to large forces for a long time and being easily damaged. When it needs to be moved, the hydraulic foot 102 contracts and breaks away from contact with the ground, thereby loosening the support for the machine tool unit 100. Then, the machine tool unit 100 can be driven to move by the moving components. After moving, the hydraulic foot 102 extends and resets.

[0042] Two slide rails 201 are provided on the base 200. The extension direction of the slide rails 201 is parallel to the length direction of the machine tool unit 100. The two slide rails 201 are arranged side by side. A rack 202 is provided on each side of the two slide rails 201 facing each other. The rack 202 and the slide rails 201 are parallel to each other.

[0043] The moving assembly comprises two rolling components arranged at the bottom of the bed frame, and the two rolling components are respectively located at two ends of the bed frame.

[0044] The rolling component includes a roller 104 whose axis is parallel to the width direction of the machine tool unit 100 and is supported by the slide rail 201 . A gear 103 is provided at the end of the roller 104 , and the gear 103 is meshed with the rack 202 .

[0045] The bed frame is provided with a driving motor 106 for driving the roller 104 to rotate.

[0046] When the roller 104 is driven to rotate by the driving motor 106, the roller 104 rotates together with the gear 103. With the cooperation of the gear 103 and the rack 202, the gear 103 can rotate while moving on the rack 202, thereby moving the roller 104 and the machine tool unit 100 together. When the two machine tool units 100 are fitted together, the two machine tool units 100 are fixedly connected by fasteners 300, including but not limited to fixation between the bed frames and fixation between the workbenches 101. The fasteners 300 can be implemented using existing fixing methods, such as bolts.

[0047] Preferred embodiment, see Figure 7 The two slide rails 201 are provided with an inclined surface on the opposite side, and the distance between the two inclined surfaces decreases in the vertical direction from bottom to top. The two rollers 104 of the rolling component are each provided with a limiting boss 105 on the opposite side. The limiting boss 105 is in the shape of a truncated cone and the outer cylindrical surface of the limiting boss 105 fits with the corresponding inclined surface; its significance lies in that during normal use, the support of the machine tool unit 100 is achieved by the hydraulic foot 102. Therefore, there is a slight gap between the roller 104 and the slide rail 201, or it is just a simple contact, which does not play a supporting role. The gear 103 remains engaged with the rack 202. When movement is required, the hydraulic foot 102 contracts. Under the action of gravity, the machine tool unit 100 has a downward trend. Under the cooperation of the outer cylindrical surface of the limiting boss 105 and the corresponding inclined surface, it can play a self-positioning role, thereby enabling the two adjacent machine tool units 100 to be accurately aligned.

[0048] Reference Figure 9 A linear rail 108 is provided on the bed frame of each machine tool unit 100. The extension direction of the linear rail 108 is parallel to the length direction of the bed frame. A slide 109 is slidably installed on the linear rail 108. The slide 109 is fixed to the bottom of the workbench 101. The bed frame is also provided with a linear module 107 for driving the workbench 101 to move along the length direction. The linear module 107 can be realized by using the existing screw linear motion technology and will not be elaborated on.

[0049] When two adjacent machine tool units 100 are spliced ​​together and a large workpiece is to be processed, the linear module 107 can be used to drive the workbench 101 to move, thereby moving the large workpiece clamped on the workbench 101 together. Therefore, any part of the large workpiece can be CNC-processed, solving the problem mentioned in the background technology that "there are limitations in CNC processing of the part of the large workpiece located at the connection between the two machine tool units."

[0050] In a preferred embodiment, on the one hand, after the two machine tool units 100 are spliced ​​and fixed, due to the large weight of the large workpiece, the slides 109 that support the workbench 101 need to be arranged in an array to have a good supporting effect. On the other hand, in the process of the linear module 107 driving the workbench 101 to move, since the moving accuracy of the workbench 101 is required to be very high, the slide 109 cannot leave the linear rail 108 and enter another linear rail 108, otherwise the moving accuracy of the workbench 101 will be affected, thereby affecting the subsequent CNC machining of large workpieces. In summary, there needs to be a distance between the slides 109 on the two sides of the multiple slides 109 on the linear rail 108 and the two ends of the linear rail 108 to avoid interfering with the subsequent movement of the workbench 101. However, this will in turn affect the supporting effect of the workbench 101, that is, the supporting effect and the moving action cannot be taken into account at the same time. In order to solve this problem:

[0051] Reference Figure 9 and Figure 10 The bottom of the workbench 101 is provided with two supporting assemblies 110 respectively close to the two ends. The supporting assembly 110 includes a supporting seat 1101 fixedly connected to the workbench 101, and a rotating rod 1102 is installed at the bottom of the supporting seat 1101. The axis of the rotating rod 1102 is parallel to the width direction of the workbench 101 and the rotating rod 1102 can rotate around the axis. The lowest point of the outer circumferential surface of the rotating rod 1102 is lower than the lower surface of the supporting seat 1101. The rotating rod 1102 contacts the linear rail 108, and the two form a rolling fit. The rotating rods 1102 are arranged in an array along the length direction of the workbench 101. There are several of them; in this way, at the beginning, the two ends of the workbench 101 are supported by two supporting components 110. When the workbench 101 needs to move later, since the supporting component 110 is in rolling cooperation with the linear rail 108 through the rotating rod 1102, unlike the sliding connection between the slide 109 and the linear rail 108, the rotating rod 1102 can roll from one linear rail 108 to another linear rail 108, thereby taking into account both the support effect of the workbench 101 and the moving accuracy of the workbench 101, and does not affect the CNC machining of large workpieces.

[0052] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention.
