[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0038] Example 1: See Figure 1 、 2 As shown, a tool setting instrument installation structure for a CNC machine tool comprises a machine tool body 1, a workbench 2 is provided on the machine tool body 1, a tool setting instrument 3 is installed on the workbench 2, and the tool setting instrument 3 is installed on the workbench 2 via a connecting mechanism;

[0039] The connecting mechanism includes a column 4 and a fixed block 5. The bottom of the fixed block 5 is installed on the workbench 2. The bottom of the column 4 is detachably connected to the top of the fixed block 5. The tool setting instrument 3 is locked and installed on the top of the column 4 by multiple first bolts 6.

[0040] In this embodiment, when the CNC machine tool is installed with the tool setter, it is quickly installed on the workbench through the column and the fixed block. During installation, the fixed block can be pre-installed on the workbench, and then the column and the fixed block can be connected, and finally the tool setter can be quickly installed on the top of the column. In this way, the installation is fast, and columns and fixed blocks of corresponding sizes can be designed according to the sizes of different tool setters. In this way, the assembly is simple, the workbench will not be occupied more, the cost is low, and the tool setting accuracy can be guaranteed, the previous tool setting time can be shortened, and the processing efficiency of the workpiece can be improved.

[0041] See also Figure 1 As shown, a workpiece positioning turntable 7 is provided in the middle of the workbench 2 , and the tool setting instrument 3 and the connecting mechanism are arranged away from the workpiece positioning turntable 7 .

[0042] In this method, the workpiece can be mounted directly on the workpiece positioning turntable, while the tool setter can be installed on the workbench without having to be disassembled, thus not affecting the normal processing of the workpiece. Furthermore, each time a product is changed, the tool setter can be quickly used to set the tool, thus ensuring the processing accuracy of each product. Of course, the tool setter can also be removed.

[0043] A plurality of first screw holes 8 are arranged around the outer edge of the top of the column 4 , and each of the first bolts 6 passes through the base of the tool setting instrument 3 and is screwed to one of the first screw holes 8 .

[0044] In this embodiment, a plurality of first screw holes are provided on the top of the column, which are used to correspond to the hole positions on the base of the tool setting instrument, so that the tool setting instrument and the column can be quickly locked and fixed by the first bolts.

[0045] See also Figure 2 As shown, an annular boss 9 extending outward is provided at the outer edge of the bottom of the column 4, and a plurality of second bolts 10 are screwed on the annular boss 9. A plurality of second screw holes 11 are provided on the top surface of the fixing block 5, which correspond one to one with the second bolts 10. Each second bolt 10 is screwed to one of the second screw holes 11, and the second bolts 10 lock the column 4 to the fixing block 5.

[0046] To facilitate quick connection and disassembly of the column and the fixing block, an annular boss is provided at the bottom of the column, a second bolt is screwed onto the annular boss, and a second screw hole is provided on the fixing block to correspond to the second bolt. When quickly connecting the column and the fixing block, the column is placed on top of the fixing block, and the second bolt is rotated so that the bottom of the second bolt is screwed into the second screw hole, thereby achieving quick locking and fixing of the column and the fixing block. The same principle applies when disassembling, which also enables quick disassembly of the column and the fixing block.

[0047] The fixing block 5 is fixed on the workbench via a locking mechanism.

[0048] In this embodiment, the locking mechanism includes a T-shaped pressing block 12 and a first locking bolt 13;

[0049] An upper hole 14 is provided on the top of the fixing block 5 , and a coaxial lower hole 15 is provided at the bottom of the upper hole 14 . The lower hole 15 is connected to the bottom surface of the fixing block 5 . The diameter of the upper hole is larger than that of the lower hole.

[0050] An inverted T-slot 16 is provided on the workbench 2, and the T-shaped pressure block 12 is inserted into the inverted T-slot 16. The bottom of the first locking bolt 13 passes through the upper hole 14 and the lower hole 15 and is connected to the T-shaped pressure block 12. The first locking bolt 13 and the T-shaped pressure block 12 lock the fixing block 5 and limit it to the workbench 2.

[0051] In the prior art, some CNC machine tools have a plurality of inverted T-slots on their workbenches, which are mainly for the convenience of fixing tooling fixtures, etc. Therefore, in this embodiment, an inverted T-slot is provided on the workbench, and its two ends are connected to the two ends of the workbench, and the top is connected to the top surface of the workbench. The T-shaped pressure block 12 includes a vertical plate 17 and a horizontal plate 18, and the bottom of the vertical plate is connected to the middle of the top surface of the horizontal plate. The inverted T-slot 16 includes a vertical groove 19 and a horizontal groove 101, and the bottom of the vertical groove is connected to the middle of the horizontal groove. The width of the horizontal groove is greater than the width of the vertical groove, and the width of the horizontal plate is greater than the width of the vertical plate. The horizontal plate is inserted into the horizontal groove, and the vertical plate is inserted into the vertical groove. The thickness and width of the horizontal plate are both smaller than the thickness and width of the horizontal groove, but the width of the horizontal plate is greater than the vertical plate. The width of the slot, the width and height of the vertical plate are also slightly smaller than the width and height of the vertical slot. When installing the fixing block, the T-shaped pressure block is inserted into the inverted T-shaped slot, and a screw hole is provided on the top of the vertical plate. Then the fixing block is placed on the workbench. In this embodiment, the top surface of the workbench is flat, not inclined or curved. Then the bottom of the first locking bolt is passed through the upper hole and the lower hole and screwed to the screw hole on the top of the vertical plate. During the screwing process, the T-shaped pressure block is pulled upward and the fixing block is moved downward at the same time, so that the top surface of the horizontal plate is against the top surface of the horizontal slot. The fixing block is tightly pressed against the top surface of the workbench, and the screw head of the top of the first locking bolt is in the upper hole, so that the first locking bolt will not leak out and will not affect the installation of the column. In this way, the fixing block can be quickly locked and installed.

[0052] Example 2: See Figure 3 、 4 As shown, a tool setting instrument installation structure for a CNC machine tool is shown. In this embodiment, its structure is basically similar to that of the first embodiment, except that: in this embodiment, the structure of the locking mechanism is different from that of the first embodiment. In this embodiment, the locking mechanism includes an inverted T-bar 21 and a nut 22.

[0053] The fixing block 5 is provided with a vertical through hole 23, and the workbench 2 is provided with an inverted T-slot 24.

[0054] The bottom of the inverted T-shaped rod 21 is inserted into the inverted T-shaped slot 24, the top of the inverted T-shaped rod 21 passes through the vertical through hole 23 and is arranged above the top surface of the fixing block 5, the nut 22 is screwed to the top of the inverted T-shaped rod 21, and the bottom surface of the nut 22 is against the top surface of the fixing block 5.

[0055] In this embodiment, the inverted T-slot 24 includes a vertical slot 25 and a horizontal slot 26, the bottom of the vertical slot is connected to the middle of the horizontal slot, and the width of the horizontal slot is greater than the width of the vertical slot. The inverted T-bar 21 includes a horizontal bar 27 and a vertical bar 28, the bottom of the vertical bar is connected to the middle of the horizontal bar, the length of the horizontal bar is greater than the diameter of the vertical bar, the length and thickness of the horizontal bar are less than the width and height of the horizontal slot, the length of the vertical bar is greater than the height of the vertical slot, and the length of the horizontal bar is greater than the width of the vertical slot. Therefore, when using, the inverted T-shaped rod is inserted into the inverted T-shaped slot in advance, the horizontal rod is in the horizontal slot, and the top of the vertical rod passes through the vertical slot and is above the top surface of the workbench. Then, the vertical through hole of the fixing block is directly opposite the vertical rod. Then, the fixing block is lowered onto the workbench, the top of the vertical rod passes through the vertical through hole and is above the top surface of the fixing block. The top outer surface of the vertical rod is provided with an external thread. Then, the nut and the vertical rod are screwed together, and the inverted T-shaped rod is pulled upward to move, so that the horizontal rod is against the top surface of the horizontal slot, and the top surface of the nut is against the top surface of the fixing block, so that it is tightly pressed against the fixed surface of the workbench. In this embodiment, the preferred inverted T-shaped rod and nut are respectively used in two groups, and the vertical through hole is used in two groups, which are respectively located on both sides of the column. This can ensure that the fixing block is firmly and balancedly locked on the workbench. In this embodiment, the use of the inverted T-shaped rod and nut arrangement, compared with the selection of the T-shaped pressing block, uses less material and is more cost-effective.

[0056] Example 3: See Figure 5 As shown, a tool setting instrument installation structure for a CNC machine tool. In this embodiment, its structure is basically similar to that of Example 1, except that: in this embodiment, the structure of the locking mechanism is different from that of the locking mechanism of Example 1. In this embodiment, the locking mechanism includes a second locking bolt 31, and the second locking bolt 31 is screwed to the fixed block 5. A positioning screw hole 32 is provided on the workbench 2, and the bottom of the second locking bolt 31 is screwed to the positioning screw hole 32.

[0057] Some existing CNC machine tools lack inverted T-slots on their worktables. This embodiment addresses this type of worktable. Therefore, to facilitate the installation of the tool setter, alignment screw holes are provided on the worktable, and corresponding screw holes are provided on the fixed block for threading the second locking bolt. When installing the fixed block, simply place it on the worktable (which should also be flat, not inclined), align the second locking bolt with the alignment screw hole, and then thread the second bolt into the alignment screw hole. This quickly locks the fixed block and worktable into position. For disassembly, reverse the rotation of the second locking bolt to separate it from the alignment screw hole for quick disassembly.

[0058] Example 4: See Figure 6 、 7As shown, a tool setting instrument installation structure for a CNC machine tool is shown. In this embodiment, its structure is basically similar to that of the first embodiment, except that: in this embodiment, the structure of the locking mechanism is different from that of the first embodiment. In this embodiment, an inverted T-slot 41 is provided on the workbench 2, and an inverted T-block 42 is provided at the bottom of the fixed block 5. The inverted T-block 42 is inserted into the inverted T-slot 41.

[0059] At least two third locking bolts 43 are screwed to the top of the fixing block 5 , and the bottoms of the third locking bolts 43 are against the top surface of the workbench 2 .

[0060] In this embodiment, the middle part of the workbench is a plane, and the sides are inclined or curved surfaces. The inclined or curved surfaces facilitate chip removal, water drainage, and other processes. The inverted T-slot 41 includes a vertical slot 44 and a horizontal slot 45. The bottom of the vertical slot is connected to the middle of the horizontal slot, and the width of the horizontal slot is greater than the width of the vertical slot.

[0061] The inverted T-block 42 includes a vertical plate 46 and a horizontal plate 47. The width of the vertical plate is smaller than the width of the horizontal plate and the fixed block. The thickness and width of the horizontal plate are both smaller than the thickness and width of the horizontal slot. The width and height of the vertical plate are also slightly smaller than the width and height of the vertical slot. The width of the horizontal plate is greater than the width of the vertical slot. The top and bottom of the vertical plate are connected to the middle of the bottom surface of the fixed block and the middle of the top surface of the horizontal plate, respectively. The length of the vertical plate is greater than the height of the vertical slot. When installing the fixed block, the inverted T-block is inserted into the inverted T-slot, with the horizontal plate in the horizontal slot, the bottom of the vertical plate in the vertical slot, and the top of the vertical plate above the top surface of the workbench. At this time, the fixed block is above the workbench. The top surface of the workbench below the fixed block can be flat, inclined, or curved. In this embodiment, taking the top surface of the workbench below the fixed block as an inclined surface (or originally a plane, but due to wear and tear over time, it has become tilted), two third locking bolts are used, one on each side of the inverted T-slot. The two third locking bolts are then screwed downward so that the bottoms of the third locking bolts rest against the top surface of the workbench, and the top surface of the horizontal plate rests against the top surface of the horizontal slot. Even if the top surface of the horizontal slot is tilted (at least one side of the horizontal plate rests against the top surface of the horizontal slot next to the vertical slot), the two third bolts can be used to rest against the corresponding positions on the top surface of the workbench to adjust the top plane of the fixed block so that the top surface of the fixed block is parallel to the horizontal plane. During the adjustment process, the angle of the downward screwing of the two third locking bolts, that is, the height of the bottom of the third bolt protruding from the bottom of the fixed block, is adjusted to adjust the rotation angle of the fixed block relative to the workbench, and to adjust the top surface angle of the fixed block, thereby ensuring the installation accuracy and tool setting accuracy of the subsequent tool setting instrument. At the same time, this debugging method is convenient and fast, and the debugging difficulty is also low.
