For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Combine the following Figures 1 to 6 , describing a cutting machine tool with floating point support according to an embodiment of the utility model.

[0040] A cutting machine tool with floating point support, comprising a first base 1 and a second base 2, wherein the first base 1 is used to support a wire cutting device, and a Y-axis driving device 3 and a workbench 4 are arranged on the top of the second base 2, wherein the Y-axis driving device 3 is used to drive the workbench 4 to move along the Y-axis direction;

[0041] A floating support assembly 5 is provided on the top of the workbench 4, and the floating support assembly 5 includes a plurality of Y-axis support plates 51 and a support cylinder 52. The workbench 4 is provided with a plurality of Y-axis support plates 51 along the X-axis direction, and both ends of the Y-axis support plates 51 are detachably connected to the workbench 4 respectively;

[0042] A plurality of the supporting cylinders 52 are slidably disposed on the workbench 4 and are located below the Y-axis supporting plate 51 to support the Y-axis supporting plate 51;

[0043] The floating support assembly 5 is used to adjust the position of the Y-axis support plate 51 on the workbench 4 .

[0044] The present invention provides a cutting machine with floating point support, wherein a Y-axis support plate 51 is provided on the workbench 4, and two Y-axis support plates 51 can support the workpiece. When the size of the workpiece changes, the floating support assembly 5 can adjust the position of the Y-axis support plate 51, so that the spacing between the two Y-axis support plates 51 changes, thereby adapting to the new workpiece. The mass of the workpiece is large, and the Y-axis support plate 51 is easily bent. At this time, the support cylinder 52 can support the Y-axis support plate 51 in the middle position of the Y-axis support plate 51, so that the Y-axis support plate 51 can always remain horizontal, thereby reducing the bending and depression of the Y-axis support plate 51, which may lead to errors in workpiece processing.

[0045] The interaction between the floating support assembly 5 and the support cylinder 52 can solve the problem that the position of the support plate on the traditional cutting machine is difficult to adjust and cannot adapt to a variety of workpieces, and the support plate is easily bent, which may cause workpiece processing errors.

[0046] Moreover, a Y-axis driving device 3 is provided between the second base 2 and the workbench 4. The Y-axis driving device 3 can timely adjust the position of the workbench 4 so that the wire cutting device on the first base 1 can cut workpieces of different shapes.

[0047] The floating support assembly 5 includes an X-axis support base plate 53 and an X-axis mounting base plate 54; the X-axis support base plates 53 are mounted on both ends of the second base 2 along the Y-axis direction, and the two ends of the Y-axis support plate 51 along the Y-axis direction are detachably connected to the two X-axis support base plates 53, and the two X-axis support base plates 53 and the two Y-axis support plates 51 form a square structure;

[0048] The second base 2 is provided with the X-axis mounting base plate 54, and the X-axis mounting base plate 54 is parallel to the X-axis supporting base plate 53. The X-axis mounting base plate 54 is detachably connected to the bottom of the supporting cylinder 52, and the top of the supporting cylinder 52 is connected to the Y-axis supporting plate 51.

[0049] In this solution, the Y-axis support plate 51 and the X-axis support base plate 53 are detachably connected, so that the staff can adjust the position of the Y-axis support plate 51 on the X-axis support base plate 53 according to the size of the workpiece, and can adjust the distance between the two Y-axis support plates 51, so as to adapt to workpieces of various sizes.

[0050] Moreover, the X-axis mounting base plate 54 is detachably connected to the supporting cylinder 52, so that the staff can synchronously adjust the position of the supporting cylinder 52 on the X-axis mounting base plate 54, so that the supporting cylinder 52 can support the middle part of the Y-axis supporting plate 51 on the X-axis mounting base plate 54, so that the Y-axis supporting plate 51 can always remain horizontal, reducing the bending and depression of the Y-axis supporting plate 51, which may lead to workpiece processing errors.

[0051] The X-axis mounting base plate 54 is connected to the supporting cylinder 52 by screws, and the X-axis supporting base plate 53 is connected to the Y-axis supporting plate 51 by screws.

[0052] The screw connection can simply and quickly install the Y-axis support plate 51 and the support cylinder 52, which not only provides a higher connection strength and can withstand a larger load, but also has higher reliability to ensure that the Y-axis support plate 51 and the support cylinder 52 are not easy to loosen after installation.

[0053] The Y-axis driving device 3 includes a Y-axis driving motor 31, a Y-axis driving screw 32, a screw nut 33 and a fixing block 34. The Y-axis driving motor 31 is rotatably mounted on the bottom wall of the workbench 4. The end of the Y-axis driving screw 32 is fixedly mounted with the Y-axis driving motor 31. The driving end of the Y-axis driving motor 31 is fixedly connected to the end of the Y-axis driving screw 32. The Y-axis driving screw 32 is movably sleeved with the screw nut 33.

[0054] The fixing block 34 is fixedly installed on the top of the second base 2, and the fixing block 34 is fixedly connected to the screw nut 33;

[0055] A limit assembly 6 and an energy-saving assembly 7 are sequentially arranged between the workbench 4 and the second base 2 along the X-axis direction. The limit assembly 6 is used to limit the moving direction of the workbench 4, and the energy-saving assembly 7 is used to reduce the energy consumption of the Y-axis driving device 3.

[0056] Start the Y-axis drive motor 31, the Y-axis drive motor 31 can drive the Y-axis drive screw 32 to rotate, and the screw nut 33 is movably connected to the Y-axis screw. Under normal conditions, the screw nut 33 will move along the Y-axis direction under the action of the Y-axis drive screw 32. However, in this solution, the screw nut 33 is fixedly connected to the fixing block 34, and the screw nut 33 is fixedly installed on the second base 2. Therefore, the Y-axis drive screw 32 rotates while moving along the Y-axis direction under the reaction force of the screw nut 33, so that the Y-axis drive device 3 can drive the workbench 4 to move along the Y-axis direction.

[0057] At this time, the limit component 6 and the energy-saving component 7 are both installed between the workbench 4 and the second base 2. The limit component 6 can limit the moving direction of the workbench 4 to prevent the workbench 4 from being displaced during the moving process; the energy-saving component 7 can reduce the energy consumption of the Y-axis drive device 3 to meet the environmental protection requirements of energy saving and emission reduction.

[0058] The energy-saving assembly 7 includes a first energy-saving guide rail 71, a second energy-saving guide rail 72 and an energy-saving roller 73, wherein the first energy-saving guide rail 71 is installed at the bottom of the workbench 4;

[0059] The second energy-saving guide rail 72 is installed on the top of the second base 2. The second energy-saving guide rail 72 is provided with a through slot 74 horizontally along the Y-axis direction. A mounting plate 75 is fixedly installed on the top of the second energy-saving guide rail 72. The mounting plate 75 is provided with a plurality of energy-saving square holes horizontally along the Y-axis direction. The energy-saving square holes are connected to the through slot 74. The bottom of the energy-saving roller 73 is located in the through slot 74. The top of the energy-saving roller 73 passes through the energy-saving square hole. The rolling direction of the energy-saving roller 73 is the Y-axis direction.

[0060] The first energy-saving guide rail 71 and the second energy-saving guide rail 72 are arranged opposite to each other, and the bottom wall of the first energy-saving guide rail 71 abuts against the rolling surfaces of the plurality of energy-saving rollers 73 .

[0061] The second energy-saving guide rail 72 is mounted at one end of the second base 2. The second energy-saving guide rail 72 is provided with a through slot 74 in the Y-axis direction, and a plurality of energy-saving rollers 73 can be placed in the through slot 74. A mounting plate 75 is mounted on the top of the second energy-saving guide rail 72, wherein the mounting plate 75 is provided with a plurality of energy-saving square holes, and the tops of the energy-saving rollers 73 pass through the energy-saving square holes. At this time, the energy-saving square holes can limit the position of the energy-saving rollers 73 to prevent the energy-saving rollers 73 from rolling out of the through slots 74.

[0062] Among them, the bottom wall of the first energy-saving guide rail 71 on the workbench 4 is in contact with the multiple energy-saving rollers 73. Since the rolling direction of the energy-saving rollers 73 is the Y-axis direction, when the workbench 4 moves in the Y-axis direction driven by the Y-axis driving device 3, the first energy-saving guide rail 71 can move along the Y-axis direction on the multiple energy-saving rollers 73. At this time, the multiple energy-saving rollers 73 roll under the action of the moving contact of the first energy-saving guide rail 71, so that the friction between the energy-saving rollers 73 and the first energy-saving guide rail 71 is converted into rolling friction, which effectively reduces the friction between the energy-saving rollers 73 and the first energy-saving guide rail 71, reduces the workload of the Y-axis driving device 3, and reduces the energy consumption and heat generation of the Y-axis driving device 3.

[0063] Since the energy-saving roller 73 is movably installed in the through groove 74, when the energy-saving roller 73 is severely worn, the staff can also take out the energy-saving roller 73 from the top of the energy-saving square hole in time and replace it with a new energy-saving roller 73, thereby extending the service life of the cutting machine tool of this scheme.

[0064] The limiting assembly 6 includes a first limiting guide rail 61, a second limiting guide rail 62 and a limiting roller 63. The first limiting guide rail 61 is installed at the bottom of the workbench 4. The bottom of the first limiting guide rail 61 has a first limiting groove.

[0065] The second limiting guide rail 62 is installed on the top of the second base 2, and the second limiting guide rail 62 is horizontally opened with a second limiting groove 64 along the Y-axis direction. A limiting plate 65 is fixedly installed on the top of the second limiting guide rail 62, and the limiting plate 65 is horizontally opened with a plurality of limiting square holes along the Y-axis direction. The limiting square holes are connected with the second limiting groove 64, and the bottom of the limiting roller 63 is tilted and located in the second limiting hole, and the top of the limiting roller 63 is tilted and passes through the limiting square hole, and the rolling surface of the limiting roller 63 is respectively in contact with the inner wall of the first limiting groove and the inner wall of the second limiting groove 64.

[0066] Reference Figure 6 The second limiting guide rail 62 is installed at the end of the second base 2 away from the second energy-saving guide rail 72. The second limiting guide rail 62 is provided with a second limiting groove 64 in the Y-axis direction, and a plurality of limiting rollers 63 can be placed obliquely in the through groove 74. A limiting plate 65 is installed on the top of the second limiting guide rail 62, wherein a plurality of limiting square holes are provided on the limiting plate 65, and the top of the limiting roller 63 obliquely passes through the limiting square hole and is then located in the first limiting groove.

[0067] When the workbench 4 moves in the Y-axis direction driven by the Y-axis driving device 3, the inner walls of the first limiting groove on the workbench 4 respectively abut against the rolling surfaces of multiple limiting rollers 63, which can effectively limit the position deviation of the workbench 4 during movement.

[0068] Moreover, the friction force between the inner walls of the first limiting grooves of the multiple limiting rollers 63 is rolling friction, which effectively reduces the friction force between the limiting rollers 63 and the first limiting guide rail 61, reduces the workload of the Y-axis drive device 3, and reduces the energy consumption and heat generation of the Y-axis drive device 3.

[0069] At this time, the limiting square hole can limit the position of the limiting roller 63 to prevent the limiting roller 63 from rolling out of the second limiting groove 64. Since the limiting roller 63 is movably installed in the second limiting groove 64, when the limiting roller 63 is seriously worn, the staff can also take out the limiting roller 63 from the top of the limiting square hole in time and replace it with a new limiting roller 63, thereby extending the service life of the cutting machine tool of this solution.

[0070] The first limiting groove and the second limiting groove 64 are both V-shaped grooves, and the rolling surface of the limiting roller 63 abuts against the inner walls of the first limiting groove and the second limiting groove 64 respectively;

[0071] The limiting roller 63 includes a first sub-limiting roller 631 and a second sub-limiting roller 632 which are arranged alternately, and the inclination directions of the first sub-limiting roller 631 and the second sub-limiting roller 632 are different. The rolling surface of the first sub-limiting roller 631 abuts against an inner wall of the first limiting groove, and the rolling surface of the second sub-limiting roller 632 abuts against the other inner wall of the first limiting groove.

[0072] Among them, the first limiting groove and the second limiting groove 64 are both V-shaped grooves, so that the limiting roller 63 can be placed in the second limiting groove 64 at an angle, and the top of the limiting roller 63 can be tilted in the first limiting groove. If the limiting rollers 63 are all set to the same tilt direction, then only one side wall of the first limiting groove can abut against the rolling surface of the limiting roller 63, the limiting effect is poor, and the workbench 4 will still be offset. Therefore, in this solution, the first sub-limiting roller 631 and the second sub-limiting roller 632 with two tilt directions are defined, so that the two side walls of the first limiting groove can abut against the rolling surface of the limiting roller 63, thereby improving the limiting effect and avoiding the workbench 4 from being offset.

[0073] The inclination direction of the first sub-limiting roller 631 and the inclination direction of the second sub-limiting roller 632 are perpendicular to each other.

[0074] This solution further limits the inclination direction of the first sub-limit roller 631 and the second limit roller 63, ensuring that the rolling surface of the first sub-limit roller 631 can abut against one inner wall of the first limit groove, and the rolling surface of the second sub-limit roller 632 can abut against the other inner wall of the first limit groove, further avoiding position displacement of the workbench 4.

[0075] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
