Description

Technical Field

[0002] The top of a traditional machine tool is a plane, with a wire cutting device placed at one end of the machine tool, and a movable plate and a workbench arranged from bottom to top at the other end of the machine tool. An X-axis guide rail is arranged between the machine tool and the movable plate, and a Y-axis guide rail is arranged between the movable plate and the workbench, to ensure that the workbench follows a predetermined control program in the two coordinate directions of the horizontal plane, thereby synthesizing various curved trajectories and cutting the workpiece into shape.

[0003] Since there are multiple structures between the workbench and the machine tool, the height of the workbench is relatively high. However, the height of the lower wire rack of the wire cutting machine sold on the market is fixed.

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

[0035] Combine the following Figures 1 to 4 , describing a stepped machine tool in an embodiment of the utility model.

[0036] A stepped machine tool comprises a first base 1 and a second base 2, wherein the first base 1 is used to support a wire cutting device, and the second base 2 is used to support a workbench 6; the end of the first base 1 is fixedly connected to the head end of the second base 2, and the top of the first base 1 is higher than the top of the second base 2;

[0037] The first base 1 and the second base 2 are both provided with a reinforcing rib assembly 3 .

[0038] Beneficial effects: A stepped machine tool of the present invention is divided into two parts, namely a first base 1 and a second base 2 . The first base 1 can support a wire cutting device, and the second base 2 can support a workbench 6 .

[0039] Since the height of the wire cutting equipment sold on the market is fixed, when placed on the first base 1, the height of the lower wire rack is fixed, and the height of the lower wire rack is lower than the height of the workbench 6, making it difficult for the wire cutting equipment to cut the workpiece. In this solution, the height of the first base 1 and the second base 2 is limited, so that the height of the first base 1 is higher than the second base 2, so that the height of the lower wire rack and the workbench 6 in the wire cutting equipment are consistent, thereby ensuring that the wire cutting equipment can cut the workpiece, solving the problem that the traditional wire cutting device is difficult to cut the workpiece after being installed on the machine tool.

[0040] Moreover, reinforcing rib assemblies 3 are provided at the bottom of the first base 1 and the second base 2 to improve the compression, bending and twisting resistance of the first base 1 and the second base 2, and solve the problems of vibration and depression in traditional machine tools during processing.

[0041] The reinforcing rib assembly 3 includes a first reinforcing rib 31, a second reinforcing rib 32 and a reinforcing plate 33, a plurality of the first reinforcing ribs 31 are evenly arranged at the bottom of the first base 1 and the second base 2, a plurality of the second reinforcing ribs 32 are evenly arranged at the bottom of the first base 1 and the second base 2, and the first reinforcing ribs 31 and the second reinforcing ribs 32 are vertically connected;

[0042] The reinforcing plate 33 is located at the bottom of the intersection of the first reinforcing rib 31 and the second reinforcing rib 32 .

[0043] The first reinforcing rib 31 and the second reinforcing rib 32 are vertically connected to each other, so that the bottom of the first base 1 and the second base 2 is a grid-like structure, which can effectively improve the structural rigidity of the first base 1 and the second base 2, and preliminarily improve the compression, bending and twisting resistance of the first base 1 and the second base 2. In addition, a reinforcing plate 33 is provided at the intersection between the first reinforcing rib 31 and the second reinforcing rib 32, and the reinforcing plate 33 can make the first base 1 and the second base 2 have higher structural strength, greater bearing capacity and stronger stability.

[0044] The reinforcing rib assembly 3 also includes a Y-shaped reinforcing rib 34. The first reinforcing rib 31 and the second reinforcing rib 32 are perpendicular to each other to form a plurality of square areas. The Y-shaped reinforcing rib 34 is arranged in the square area. The three ends of the Y-shaped reinforcing rib 34 are fixedly connected to the first reinforcing rib 31 and the second reinforcing rib 32 respectively.

[0045] In the plurality of square regions, Y-shaped reinforcing ribs 34 are arranged. Compared with the conventional cross-shaped reinforcing ribs, the three ends of the Y-shaped reinforcing ribs 34 of the present solution can be respectively fixedly connected with the adjacent first reinforcing ribs 31 and the second reinforcing ribs 32, thereby improving the connection relationship between the first reinforcing ribs 31 and the second reinforcing ribs 32, thereby making the structure more reliable, ensuring that the first base 1 and the second base 2 will not be deformed under a large load, and can effectively reduce the vibration of the first base 1 and the second base 2 when processing the workpiece.

[0046] Two adjacent Y-shaped reinforcing ribs 34 are symmetrically arranged about the Y axis.

[0047] Reference Figure 3 The two adjacent Y-shaped reinforcing ribs 34 in the Y-axis direction are symmetrically arranged in the X-axis direction, and the two adjacent Y-shaped reinforcing ribs 34 in the X-axis direction are relatively arranged, which can further enhance the bending, compression and torsion resistance of the first reinforcing rib 31 and the second reinforcing rib 32, and improve the bearing capacity of the first base 1 and the second base 2.

[0048] A plurality of circular holes 35 are evenly formed at the bottom of the first reinforcing rib 31, and the centers of the circular holes 35 on the plurality of first reinforcing ribs 31 are all on a straight line;

[0049] The thickness of the Y-shaped reinforcing rib 34 is smaller than the thickness of the first reinforcing rib 31 , and the circular hole 35 is located at the bottom of the Y-shaped reinforcing rib 34 .

[0050] A plurality of circular holes 35 are provided at the bottom of the first reinforcing rib 31 , which can save the material of the first reinforcing rib 31 and achieve the purpose of saving costs. Moreover, the circular shape can ensure that the stress is concentrated toward the center of the circle and ensure rigidity.

[0051] Moreover, in order to further ensure that the end of the Y-shaped reinforcing rib 34 can be connected to the first reinforcing rib 31 , the position of the circular hole 35 is limited so that the circular hole 35 is located at the bottom of the Y-shaped reinforcing rib 34 .

[0052] A plurality of X-axis guide rails 21 are evenly arranged on the top of the second base 2, and a plurality of X-axis sliders 22 are slidably connected to the X-axis guide rails 21. A third base 4 is fixedly connected to the side of the X-axis slider 22 away from the X-axis guide rail 21, and the bottom of the third base 4 is fixedly connected to the plurality of X-axis sliders 22, and the length direction of the third base 4 is the Y-axis direction;

[0053] An X-axis driving assembly 23 is also provided on the top of the second base 2, and the driving end of the X-axis driving assembly 23 is fixedly connected to the bottom of the third base 4. The X-axis driving assembly 23 is used to drive the third base 4 to move along the X-axis, and the third base 4 is used to support the workbench 6.

[0054] According to actual production needs, the workpiece needs to be cut into various shapes, so the workbench 6 needs to move in multiple directions so that the workpiece can be cut into a specific shape. Therefore, an X-axis drive assembly 23 is provided on the second base 2. The X-axis drive assembly 23 drives the third base 4 to move back and forth in the X-axis direction. Among them, the third base 4 is provided with an X-axis slider 22, and the second base 2 is provided with an X-axis guide rail 21. The X-axis slider 22 is slidably connected with the X-axis guide rail 21, so that the X-axis guide rail 21 can limit the movement direction and range of the third base 4.

[0055] A Y-axis guide rail 41 and a Y-axis driving assembly 43 are provided on the top of the third base 4. The two Y-axis guide rails 41 are provided at the left and right ends of the third base 4. The Y-axis guide rail 41 is slidably connected with a Y-axis slider 42. The workbench 6 is fixedly installed on the side of the Y-axis slider 42 away from the Y-axis guide rail 41. The driving end of the Y-axis driving assembly 43 is fixedly connected to the bottom of the workbench 6. The Y-axis driving assembly 43 is used to drive the workbench 6 to move along the Y-axis.

[0056] The Y-axis driving assembly 43 is started, and the Y-axis driving assembly 43 can drive the workbench 6 to move back and forth in the Y-axis direction. Since the bottom of the workbench 6 is fixedly connected to the Y-axis slider 42, a Y-axis guide rail 41 is provided on the third base 4, and the Y-axis guide rail 41 and the Y-axis slider 42 are slidably connected, so that the Y-axis guide rail 41 can play a role of limiting, which not only limits the workbench 6 to move only along the Y-axis direction, but also limits the range of movement of the workbench 6.

[0057] At this time, the X-axis driving assembly 23 and the Y-axis driving assembly 43 cooperate with each other so that the workbench 6 can move in the X-axis direction and the Y-axis direction, thereby ensuring that the workpiece can be cut into a specific shape.

[0058] The X-axis drive assembly 23 has the same structure as the Y-axis drive assembly 43. The X-axis drive assembly 23 includes a motor 5, a screw rod 51 and a drive slider 52. The output end of the motor 5 is fixedly connected to the screw rod 51, and the screw rod 51 is movably sleeved with the drive slider 52.

[0059] The motor 5 of the X-axis driving member is installed on the top of the second base 2, the screw rod 51 of the X-axis driving assembly 23 is rotatably installed on the top of the second base 2, and the length direction is the X-axis direction, and the driving slider 52 of the X-axis driving assembly 23 is connected to the third base 4;

[0060] The motor 5 of the Y-axis driving member is installed on the top of the third base 4, so the screw rod 51 of the Y-axis driving component 43 is rotatably installed on the top of the third base 4, and the length direction is the X-axis or Y-axis, and the driving slider 52 of the Y-axis driving component 43 is fixedly connected to the workbench 6.

[0061] It is worth noting that the structures of the X-axis drive assembly 23 and the Y-axis drive assembly 43 are basically the same, and both include a motor 5, a screw rod 51, and a drive slider 52. Among them, the output end of the motor 5 is fixedly connected to the screw rod 51, and the drive slider 52 is movably sleeved on the screw rod 51. When the motor 5 drives the screw rod 51 to rotate, the drive slider 52 can move on the screw rod 51. Since the two drive sliders 52 are fixedly connected to the third base 4 and the workbench 6 respectively, the motor 5 of the X-axis drive assembly 23 can drive the third base 4 to move along the X-axis, and the motor 5 of the Y-axis drive assembly 43 can drive the workbench 6 to move along the Y-axis.

[0062] The X-axis driving assembly 23 and the Y-axis driving assembly 43 cooperate with each other to ensure that the workpiece can be cut into various specific shapes.

[0063] The first base 1 and the second base 2 are integrally formed, which can achieve the effects of simpler casting process, compact structure and higher rigidity.

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.
