Description

Technical Field

[0001] This application relates to the field of cutting machine technology, and in particular to an integrated dual-head device and a cutting machine. Background Technology

[0002] To improve processing efficiency, cutting machines often need to be equipped with dual cutting heads, and the cutting tools mounted on the dual cutting heads perform collaborative cutting operations. Existing solutions typically involve mechanically combining two independent single cutting heads.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0041] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0042] It should be noted that the "upper end, lower end, left side, right side" and other orientation words described below are defined based on the drawings of the specification.

[0043] The embodiments of the present application provide a cutting machine for independently adjusting the height of two machine heads and adjusting the cutting angle of the cutter on the machine head, which has the effects of low cost and small operation difficulty.

[0044] The integrated double-head device includes two machine heads and cutters arranged on the machine heads, wherein the machine head includes a machine shell, a power source and a cutter clamping device, the power source and the cutter clamping device are arranged in the machine head, the power source is used to drive the cutter to vibrate at high frequency, and the cutter clamping device is used to fix the cutter.

[0045] The integrated double-head device further includes a fixed seat 1 and a lifting assembly 2, referring to the accompanying drawings Figure 1 -Appendix Figure 2 The lifting assembly 2 is arranged on the fixed seat 1 in a lifting manner. The fixed seat 1 is the supporting foundation of the whole device, and the fixed seat 1 includes a fixed bottom plate 3, a ball screw 6 and a first motor 4. The first motor 4 is fixedly installed on the fixed bottom plate 3, and the output end of the first motor 4 is connected with the ball screw 6 through a shaft coupling 5, so as to drive the ball screw 6 to rotate. The length extension direction of the ball screw 6 is the Z-axis direction in the accompanying drawings. Figure 1 The ball screw 6 is connected with a screw nut 7, and the screw nut 7 is arranged on the fixed bottom plate 3. The screw nut 7 is connected with a first guide rail 8 through a second motor 9, and the second motor 9 is arranged on the fixed bottom plate 3.

[0046] Referring to the drawings Figure 2 The length extension direction of the fixed base plate 3 is arranged along the direction of the Z axis, and the bottom thereof is further provided with two symmetrically arranged stop blocks for supporting the fixed base plate 3. The first motor 4 is installed on the top of the fixed base plate 3 and connected with the fixed base plate 3 through a motor base. The extension direction of the ball screw 6 corresponds to the arrangement direction of the fixed base plate 3, and is also arranged vertically along the direction of the Z axis.

[0047] The lifting assembly 2 comprises a sliding base plate 10 connected with the outer side of the ball screw 6. The sliding base plate 10 is driven to lift by the forward and reverse rotation of the ball screw 6, thereby driving the lifting assembly 2 to move up and down.

[0048] Referring to the drawings Figure 1 -Appendix Figure 3 The sliding base plate 10 is arranged on the fixed base plate 3 in the positive direction of the Z axis, and the sliding base plate 10 is also parallel to the fixed base plate 3.

[0049] Specifically, the sliding base plate 10 is connected with a screw nut 7, and the ball screw 6 is threadedly connected with the screw nut 7. The fixed base plate 3 is provided with a first guide rail 8 for guiding the lifting assembly 2, and the lifting assembly 2 is used to slide along the first guide rail 8.

[0050] In one possible implementation, when the first motor 4 is started and transmits power to the ball screw 6 through the coupling 5, the ball screw 6 is driven to rotate around its own axis. At the same time, in order to ensure that the lifting assembly 2 only performs lifting motion, at least one first guide rail 8 is arranged on the fixed base plate 3 and parallel to the axial direction of the ball screw 6, and the lifting assembly 2 is slidably connected with the first guide rail 8 through a sliding block. Through the arrangement of the first guide rail 8, on the one hand, the lifting of the lifting assembly 2 is guided, and on the other hand, the lifting assembly 2 and the connected screw nut 7 are restricted from rotating with the ball screw 6.

[0051] One implementation is that when the ball screw 6 rotates, the screw nut 7 is restricted by the first guide rail 8 and cannot rotate, but only moves along the axial direction of the ball screw 6. By controlling the forward or reverse rotation of the first motor 4, the lifting assembly 2 is driven to realize the actions of rising or falling, so as to adjust the machining height of the two head assemblies as a whole.

[0052] Specifically, the lifting assembly 2 comprises a rotating assembly, a first assembly 12 and a second assembly 13.

[0053] Referring to the drawings Figure 4 and Appendix Figure 6, the first assembly 12 and the second assembly 13 are symmetrically arranged on the integrated double-head device, the first assembly 12 comprises a first tool shaft seat 22 and a first gear 20, and the rotation axis of the first gear 20 is perpendicular to the plane formed by the X axis and the Y axis, that is, the Z axis direction, that is, any one of the X axis, the Y axis and the Z axis is perpendicular to the other two. The second assembly 13 comprises a second tool shaft seat 27 and a second gear 24, and the rotation axis of the second gear 24 is also perpendicular to the plane formed by the X axis and the Y axis. The rotating assembly comprises a second motor 9 and a driving wheel 18, and the driving wheel 18 is installed on the sliding base plate 10.

[0054] One of the two heads is mounted on the first assembly 12, and the other head is mounted on the second assembly 13, the rotating assembly is connected with the first assembly 12 and the second assembly 13, the first assembly 12 and the second assembly 13 are arranged on opposite sides of the rotating assembly respectively, and the rotating assembly is used for driving the first assembly 12 and the second assembly 13 to rotate, so as to adjust the rotation angle of the head and change the cutting angle of the tool.

[0055] In an embodiment, the sliding base plate 10 is further connected with a first plate 16 and a second plate 17, and the driving wheel 18 is rotatably installed between the first plate 16 and the second plate 17 through a first bearing 19. The output end of the second motor 9 is connected with the shaft center of the driving wheel 18, and the driving wheel 18 is driven to rotate by the driving action of the second motor 9.

[0056] Referring to the accompanying drawings Figure 3 In order to provide a stable mounting position for the driving wheel 18 and the second motor 9, one end (in the X axis direction) of the sliding base plate 10 is fixedly connected with the first plate 16 and the second plate 17, and the first plate 16 and the second plate 17 are connected with each other. The top surface of the first plate 16 is consistent with the top of the sliding base plate 10 and smoothly transitions, and together forms a mounting platform for mounting the second motor 9.

[0057] The first assembly 12 is connected with the first gear 20, the second assembly 13 is connected with the second gear 24, the driving wheel 18 is engaged with the first gear 20 and the second gear 24, the first gear 20 and the second gear 24 are driven to rotate by the rotation of the driving wheel 18, so as to adjust the rotation angle of the first assembly 12 and the second assembly 13. The first gear 20 and the second gear 24 are located on opposite sides of the driving wheel 18 respectively.

[0058] The sliding base plate 10 is provided with a second guide rail 11 for guiding the first assembly 12, and the sliding base plate 10 is further provided with a third guide rail 15 for guiding the second assembly 13, the first assembly 12 is used for sliding along the second guide rail 11, and the second assembly 13 is used for sliding along the third guide rail 15;

[0059] The tooth height range of the driving wheel 18 covers the effective sliding stroke of the second guide rail 11 and the third guide rail 15, so as to ensure that the driving wheel 18 is always in engagement with the first gear 20 and the second gear 24 during the lifting of the first assembly 12 or the second assembly 13. That is, no matter the first assembly 12 and the second assembly 13 are at any height position in the respective lifting stroke, the first gear 20 and the second gear 24 thereon can always be in stable and reliable engagement with the tooth surface of the driving wheel 18.

[0060] In a possible implementation, in order to adjust the cutting angle of the cutter on the head, the second motor 9 of the rotating assembly and the driving wheel 18 are cooperated, specifically: power is sent out by the second motor 9 to drive the driving wheel 18 to rotate, the first assembly 12 and the first gear 20 are coaxially fixed, the second assembly 13 and the second gear 24 are coaxially fixed, and the driving wheel 18 is always in engagement with the first gear 20 and the second gear 24. When the driving wheel 18 rotates, the first gear 20 and the second gear 24 are synchronously applied with a rotating torque, and then the cutting angle of the cutter on the head is adjusted.

[0061] Specifically, the first assembly 12 is connected with the first cylinder 26, and the second assembly 13 is connected with the second cylinder 14, and the first cylinder 26 and the second cylinder 14 are respectively used to independently control the lifting adjustment of the two heads.

[0062] The first assembly 12 includes a first connecting seat 21, the first connecting seat 21 is rotatably connected with a first cutter shaft seat 22 through a second bearing 23, and the first gear 20 is coaxially fixedly connected with the first cutter shaft seat 22. The second assembly 13 includes a second connecting seat 25, the second connecting seat 25 is rotatably connected with a second cutter shaft seat 27 through a third bearing 28, and the second gear 24 is coaxially fixedly connected with the second cutter shaft seat 27.

[0063] The first cylinder 26 includes a cylinder body and a piston rod, the piston rod can be telescopically moved relative to the cylinder body, and similarly to the first cylinder 26, the second cylinder 14 also includes a cylinder body and a piston rod, the piston rod can be telescopically moved relative to the cylinder body; the piston rod of the first cylinder 26 is connected with the first assembly 12 and is used to drive the first assembly 12 to slide along the second guide rail 11. The piston rod of the second cylinder 14 is connected with the second assembly 13 and is used to drive the second assembly 13 to slide along the third guide rail 15.

[0064] In one embodiment, there are first air cylinders 26 and second air cylinders 14, the cylinder bodies of which are fixed above the first plate 16, the first assembly 12 is driven by the first air cylinders 26 to perform precise lifting adjustment, the second assembly 13 is driven by the second air cylinders 14 to perform precise lifting adjustment, so that the heights of the two heads can be adjusted, and this design allows one head to remain stationary or in a raised state, while the other head is lowered for processing, which has high flexibility.

[0065] In one possible embodiment, in order to ensure the stability of the lifting actions of the first assembly 12 and the second assembly 13, a second guide rail 11 is arranged on the sliding base plate 10, which is used to constrain the sliding direction of the first assembly 12. A third guide rail 15 is arranged on the sliding base plate 10, which is used to constrain the sliding direction of the second assembly 13. In this way, it is ensured that the first assembly 12 and the second assembly 13 can only move up and down in a straight line, thereby ensuring the accuracy of the tool processing.

[0066] In summary, when it is necessary to independently lift the heads, the actions of the first air cylinders 26 and the second air cylinders 14 are controlled to drive the first assembly 12 or the second assembly 13 to move up and down along the respective guide rails. During this movement, no matter what height the first gear 20 and the second gear 24 are at in their stroke, they are always in meshing state with the tooth surface of the driving wheel 18. Therefore, when it is necessary to adjust the cutting angle, the second motor 9 can be started at any time to drive the driving wheel 18 to rotate, and through the transmission of the rotation, the first gear 20 and the second gear 24 at different heights are driven to rotate synchronously, and then the first tool shaft seat 22 and the second tool shaft seat 27 connected with the heads are driven to rotate synchronously, so that the cutting angle of the tool is adjusted.

[0067] It should be noted that in the present specification, relational terms such as first and second are used only to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between these entities.
