Description

Technical Field

[0001] The invention relates to the field of machine tools, and in particular to a CNC machining machine tool that can be 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 workpiece that can be processed by the 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, in the prior art, large machine tools cannot be formed in one piece. Therefore, it is generally necessary to use a splicing process to assemble several modules into a completed CNC machine tool. Based on this, the following concept is proposed in the prior art: multiple machine tool units can be spliced ​​in series into 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 realize the serial splicing between multiple machine tool units. Since the processing system of the machine tool unit has its moving 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 machining 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 solution adopted by the present invention is as follows.

[0006] A CNC machining machine tool that can be spliced ​​and connected, comprising a base and a plurality of machine tool units installed side by side on the base, a bed frame and a workbench of the machine tool units, a moving assembly is arranged at the bottom of the machine tool units, and the moving assembly is used to drive the machine tool units to move, so that two adjacent machine tool units fit each other, and then the two machine tool units are fixedly connected by fasteners; 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, the slide is fixed to the bottom of the workbench, and the bed frame is also provided with a linear module for driving the workbench to move along the length direction.

[0007] As a further improvement and optimization of the present invention, a plurality of slide seats are arranged in an array on each linear rail, and there is a distance between the slide seats on the two most sides of the plurality of slide seats on the linear rail and the two ends of the linear rail; The bottom of the workbench is provided with two supporting components close to both ends respectively, and the supporting components and the linear rail form rolling contact cooperation.

[0008] As a further improvement and optimization of the present invention, the supporting assembly includes a supporting seat fixedly connected to the workbench, 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.

[0009] 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.

[0010] 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, and during normal use, the machine tool unit is supported by the hydraulic feet.

[0011] As a further improvement and optimization of the present invention, two slide rails are arranged on the base, and 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 respectively provided on the opposite side of the two slide rails. The rack and the slide rails are parallel to each other, and the moving assembly includes two rolling components arranged at the bottom of the bed frame, and the two rolling components are respectively located at both ends of the bed frame.

[0012] 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, and a gear is provided at the end of the roller, and the gear is meshed with the rack.

[0013] As a further improvement and optimization of the present invention, a driving motor for driving the roller to rotate is arranged on the bed frame, and a worm gear is included in the power transmission route between the roller and the driving motor.

[0014] 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.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This solution adopts a modular design and sets up several machine tool units. The machine tool units can move and connect in series, and are assembled into a large machine tool, which 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 efficiency and market competitiveness.

An inclined plane is arranged on the opposite side of the two slide rails, and the distance between the two inclined planes decreases along the vertical direction from bottom to top. A limiting boss is arranged 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 plane. Its significance lies in that, in normal use, the support of the machine tool monomer is realized 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 components. When it is necessary to move, the hydraulic foot shrinks, and under the action of gravity, the machine tool monomer has a downward movement tendency. Under the cooperation of the outer cylindrical surface of the limiting boss and the corresponding inclined plane, it can play a self-positioning role, so that the two adjacent machine tool monomers can be accurately aligned. 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, so that any part of the large workpiece can be processed by CNC, which solves 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"; On this basis, two supporting assemblies are provided at the bottom of the workbench, respectively, close to the two ends. In this way, at the beginning, the support of the two ends of the workbench is achieved by the two supporting assemblies. When the workbench needs to be moved later, the supporting assemblies are in rolling cooperation with the linear rail through a rotating rod, unlike the sliding connection between the slide seat 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 motion accuracy of the workbench, and not affecting the CNC machining of large workpieces.

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] This plan is attached Fig.11 With attached Fig.12 In the figure, a refers to the contact position of the linear rails 108 on the two workbenches 101 after the two machine tool units 100 are assembled and spliced, which is indicated by a thick line.

[0020] Reference Figure 3-Figure 12 A CNC machine tool 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 processing system of the machine tool unit 100, etc. These are all achievable by existing technologies and will not be described in detail.

[0021] In this solution, two machine tool units 100 are taken as an example for explanation.

[0022] A moving assembly is disposed 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 attached to each other.

[0023] Specifically, refer to Figure 6-Figure 8A 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 herein. 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 weight of the machine tool unit 100 is large, it is necessary to prevent the moving components from being easily damaged by being subjected to large forces for a long time. When it is necessary to move, the hydraulic foot 102 contracts and breaks away from contact with the ground, thereby releasing the support for the machine tool unit 100. Then, the machine tool unit 100 can be driven to move through the moving components. After moving, the hydraulic foot 102 is extended and reset.

[0024] 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 of the two facing sides of the slide rails 201 . The rack 202 and the slide rails 201 are parallel to each other.

[0025] 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.

[0026] 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 .

[0027] A driving motor 106 for driving the roller 104 to rotate is arranged on the bed frame.

[0028] 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 the fasteners 300, including but not limited to fixation between the bed frames and fixation between the workbenches 101. The fasteners 300 can be implemented by existing fixing methods, such as bolts.

[0029] Preferred embodiment, refer to Figure 7, an inclined plane is arranged on the opposite side of the two slide rails 201, and the distance between the two inclined planes decreases along the vertical direction from bottom to top. A limiting boss 105 is arranged on the opposite side of the two rollers 104 of the rolling component, and 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 plane; its significance lies in that, in normal use, the support of the machine tool monomer 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 keeps meshing with the rack 202. When it is necessary to move, the hydraulic foot 102 contracts. Under the action of gravity, the machine tool monomer 100 has a downward tendency. Under the cooperation of the outer cylindrical surface of the limiting boss 105 and the corresponding inclined plane, it can play a self-positioning role, so that the two adjacent machine tool monomers 100 can be accurately aligned.

[0030] Reference Fig. 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. A linear module 107 for driving the workbench 101 to move along the length direction is also provided on the bed frame. The linear module 107 can be realized by using the existing screw linear motion technology and will not be elaborated on.

[0031] 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."

[0032] In the preferred embodiment, on the one hand, after the two machine tool monomers 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 achieve 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 very high, the slide 109 cannot be separated from the linear rail 108 and enter another linear rail 108, otherwise it will affect the moving accuracy of the workbench 101, 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, but this will cause the supporting effect of the workbench 101 to be affected, that is, the supporting effect and the moving action cannot be taken into account at the same time. In order to solve this problem: Reference Fig. 9 and Fig.10 The bottom of the workbench 101 is provided with two supporting assemblies 110 respectively close to the two ends, and 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 line 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 line. The lowest point of the outer cylindrical surface of the rotating rod 1102 is lower than the lower surface of the supporting seat 1101. The rotating rod 1102 contacts with 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 assemblies 110. When the workbench 101 needs to move later, since the supporting assembly 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. Therefore, both the supporting effect of the workbench 101 and the moving accuracy of the workbench 101 are taken into account, and the CNC machining of large workpieces is not affected.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
