After the tool is installed on the tool spindle, the tool is driven to rotate at high speed to achieve processing. Using the tool for milling, drilling and other processes has the advantage of rapid material removal.

[0004] In fact, the CNC machine tool is only partially assembled before being shipped from the factory. The Y-axis saddle and the tool spindle box can slide freely, and the tool spindle will extend from the bottom of the tool spindle box. In order to prevent the tool spindle box and tool spindle from being damaged during the transportation of the CNC machine tool, how to fix the tool spindle box and protect the tool spindle is an urgent problem to be solved. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present utility model is to provide a tool spindle transportation protection structure, which is intended to fix the tool spindle box and protect the tool spindle.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A tool spindle transportation protection structure comprises a Y-axis crossbeam, a Y-axis saddle slidably arranged on the Y-axis crossbeam along the Y-axis, a spindle box slidably arranged on the Y-axis saddle along the Z-axis, and a tool spindle arranged on the spindle box, wherein the axis of the tool spindle extends vertically and the output end of the tool spindle extends from the bottom of the spindle box, and is characterized in that a protective frame is provided at the bottom of the spindle box to surround the output end of the spindle box; the spindle box and the Y-axis saddle are fixedly connected by a locking block and a locking screw, and the Y-axis saddle is fixedly connected to the Y-axis crossbeam by a locking seat and a locking screw.

[0008] As a further improvement of the above technical solution, the protective frame includes a bottom plate, a back plate vertically arranged on the bottom plate, and two side plates; in the top-down projection, the back plate and the two side plates enclose a "冂"-shaped to form an inner cavity, and horizontal wing plates are provided on the outer sides of the two side plates, and a first mounting hole is opened on each wing plate.

DETAILED DESCRIPTION

[0020] The utility model provides a tool spindle transport protection structure. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0021] See also Figure 1-Figure 3 The utility model provides a tool spindle 14 transportation protection structure, including a Y-axis crossbeam 11, a Y-axis saddle 12 which can be slidably arranged on the Y-axis crossbeam 11 along the Y-axis, a spindle box 13 which can be slidably arranged on the Y-axis saddle 12 along the Z-axis, and a tool spindle 14 arranged on the spindle box 13, the axis of the tool spindle 14 extends vertically and the output end of the tool spindle 14 extends from the bottom of the spindle box 13, and the bottom of the spindle box 13 is provided with a protection frame 2 which surrounds the output end of the spindle box 13; the spindle box 13 and the Y-axis saddle 12 are fixedly connected by a locking block 3 and a locking screw, and the Y-axis saddle 12 is fixedly connected to the Y-axis crossbeam 11 by a locking seat 4 and a locking screw.

[0022] When the CNC machine tool is shipped, the sliding assembly of the Y-axis saddle 12 and the spindle box 13 has been completed on the CNC machine tool. Since the Y-axis drive mechanism and the Z-axis drive mechanism need to be传动调试 (transmission debugging) after the CNC machine tool is transported to the destination, they do not form a transmission relationship with the Y-axis saddle 12 and the spindle box 13. Therefore, the Y-axis saddle 12 can move freely along the Y-axis, and the spindle box 13 can move automatically along the Z-axis. A tool spindle 14 is provided on the spindle box 13, and the output end of the tool spindle 14 extends from the bottom of the spindle box 13. In order to prevent the spindle box 13 from moving on its own during transportation and the tool spindle 14 from being damaged, before shipping, the protective frame 2 is first installed at the bottom of the spindle box 13 so that the protective frame 2 can provide external protection for the output end of the tool spindle 14. Then, by moving the Y-axis saddle 12 and the spindle box 13, the spindle box 13 is moved directly above the workbench 5 (the workbench 5 has been pre-fixed) of the CNC machine tool, and the spindle box 13 is slowly lowered so that the protective frame 2 presses against the workbench 5. The weight of the spindle box 13 is supported by the workbench 5. Then, the protective frame 2 is fixed to the workbench 5 again so that the protective frame 2 cannot be separated from the workbench 5, ensuring that the spindle box 13 cannot move on its own during transportation and preventing the spindle box 13 from being damaged due to strong vibration or collision, thus protecting the tool spindle 14.

[0023] It should be noted that since the weights of the Y-axis saddle 12 and the spindle box 13 are relatively large, once the CNC machine tool tilts or vibrates during transportation, the Y-axis saddle 12 and the spindle box 13 will generate a large amount of kinetic energy of motion, which is likely to cause the failure of the above-mentioned transportation protection structure for the tool spindle 14. Therefore, in order to better ensure the stability of the transportation protection structure for the tool spindle 14, the Y-axis saddle 12 is fixed on the Y-axis crossbeam through the locking seat 4 and locking screws, and the spindle box 13 is locked on the Y-axis saddle 12 through the locking block 3 and locking screws, ensuring that the Y-axis saddle 12 and the spindle box 13 will not slip during transportation.

[0024] Specifically, the protective frame 2 includes a bottom plate 21, a back plate 22 vertically arranged on the bottom plate 21, and two side plates 23. In the top view projection, the back plate 22 and the two side plates 23 enclose a "冂" shape to form an inner cavity 27. Horizontal wing plates 24 are provided on the outer sides of the two side plates 23. A first mounting hole 241 is opened on each wing plate 24. A third threaded hole corresponding to the first mounting hole 241 is provided at the bottom of the spindle box 13. The fifth locking screw passes through the first mounting hole 241 from bottom to top and is screwed into the third threaded hole, thereby fixing the protective frame 2 on the spindle box 13. On the one hand, the protective frame 2 provides external protection for the output end of the tool spindle 14, and on the other hand, it serves as a fixing medium between the spindle box 13 and the workbench 5.

[0025] In fact, an operation window is formed in front of the protection frame 2 to connect the inner cavity 27 of the protection frame 2 to the outside. The bottom plate 21 is provided with a plurality of second mounting holes 211. In addition to the horizontal workbench 5, the bed can also be provided with a cradle turntable to realize multi-axis processing, that is, the protection frame 2 can be fixed on the workbench 5 / cradle turntable. The workbench / 5 cradle turntable has a clamping slot. After the head of the locking bolt is inserted into the clamping slot, it passes through the second mounting hole 211 and is tightened and fixed with a nut. The staff can extend their hands into the operation window to enter the inner cavity 27 for operation.

[0026] In order to strengthen the structural strength of the wing plate 24 to prevent the wing plate 24 from being deformed by pressure, an H-shaped frame 25 is connected to the bottom of the wing plate 24, the inner side of the H-shaped frame 25 is connected to the side plate 23, and the bottom of the H-shaped frame 25 is connected to the bottom plate 21, so that the H-shaped frame 25 provides stable support for the wing plate 24.

[0027] Preferably, an inner strip 26 is provided in the inner cavity 27 to strengthen the connection between the back plate 22 and the two side plates 23 .

[0028] Preferably, the side panel 23 is in a right-angle trapezoidal shape. By arranging in this way, the front corners of the side panel 23 can be eliminated to prevent the corners from hindering the operation of the staff.

[0029] Specifically, the locking block 3 is a bent structure, with a first waist-shaped hole 31 on one end of the locking block 3 and a second waist-shaped hole 32 on the other end. The first waist-shaped hole 31 extends along the Z-axis direction, and the second waist-shaped hole 32 extends along the X-axis direction. The spindle box 13 is provided with the same number of first threaded holes as the first waist-shaped holes 31 and one-to-one corresponding to each other, and the Y-axis slide saddle 12 is provided with the same number of second threaded holes as the second waist-shaped holes 32 and one-to-one corresponding to each other. A first locking screw (not shown in the figure) matching the first threaded hole on the spindle box 13 is installed at the first waist-shaped hole 31, and a second locking screw (not shown in the figure) matching the second threaded hole on the Y-axis slide saddle 12 is installed at the second waist-shaped hole 32. Tightening the first locking screw and the second locking screw can fix the spindle box 13 and limit the vertical movement of the spindle box 13. The first waist-shaped hole 31 and the second waist-shaped hole 32 also ensure that the first locking screw and the second locking screw have enough surplus for installation.

[0030] In this embodiment, two locking blocks 3 are provided.

[0031] Furthermore, the locking seat 4 includes a stand 41 fixed on the top of the Y-axis beam 11 and an L-shaped plate 42 arranged in front of the stand 41, the L-shaped plate 42 includes a vertical plate 421 and a flat plate 422, the vertical plate 421 is provided with a third waist-shaped hole 43 extending along the Z-axis direction, the flat plate 422 is provided with a fourth waist-shaped hole 44 extending along the X-axis direction, the stand 41 is provided with the same number of third threaded holes as the third waist-shaped holes 43 and one-to-one corresponding, and the Y-axis saddle 12 is provided with the same number of fourth threaded holes as the fourth waist-shaped holes 44 and one-to-one corresponding. The third waist-shaped hole 43 is installed with a third locking screw (not shown in the figure) that matches the third threaded hole on the stand 41, and the fourth waist-shaped hole 44 is installed with a fourth locking screw (not shown in the figure) that matches the fourth threaded hole on the Y-axis saddle 12. Tightening the third locking screw and the fourth locking screw can fix the Y-axis saddle 12 and limit the left and right movement of the Y-axis saddle 12. The third waist-shaped hole 43 and the fourth waist-shaped hole 44 also ensure that the third locking screw and the fourth locking screw have sufficient margin for installation.

[0032] In this embodiment, the locking seat 4 is provided with two pieces.
