The main body 21 is formed with three support columns 210 extending upward and downward, and the support columns 210 are respectively provided with three mounting hole groups 211. Each mounting hole group 211 has five mounting holes 212 arranged in order from the bottom. The distance between two adjacent mounting hole groups 211 is 300 mm, and the installation The distance between the highest and lowest two mounting holes 212 in the hole group 211 is 100 to 300 mm, which is 150 mm in this embodiment. A plurality of hanging holes 213 are defined in the bottom of the body 21.

The first X-axis slide rail 22 and the second X-axis slide rail 23 are respectively disposed on the top surface of the body 21, and the first X-axis slide rail 22 is not equal to the second X-axis slide rail 23, that is, The slide rails are closer to the mounting hole group 211 than the mounting rails. The upper surface of the first X-axis slide rail 22 is higher than the upper surface of the second X-axis slide rail 23, and the vertical distance therebetween is 90 to 110 mm, which is 100 mm in this embodiment. The first X-axis slides 24 are mounted on the first X-axis slide rail 22. The second X-axis sliders 25 are also mounted on the second X-axis slide rail 23.

A second Y-axis slider 34 is disposed on the second Y-axis slide 32. After the linear sliding rail of the Y-axis (ie, the combination of the Y-axis slide rails 31, 32 and the Y-axis sliders 33, 34) is assembled, the first Y-axis slider 33 and the second Y-axis are further The slider 34 is snapped to the top of the saddle 3.

The above-mentioned Y-axis linear slide rail mounting method is different from the conventional one. The conventional mounting method is to fix the slide rail, then set the slider, and set the sliding object on the slider, that is, the slider carries the sliding object. . However, the present invention is to allow the slide rail to carry the sliding object (ie, the column 4) to be installed in an upside down manner, that is, the first Y-axis slider 33 and the second Y-axis slider 34 are mounted thereon. The saddle 3 is mounted on the column 4 and the first Y-axis rail 31 and the second Y-axis rail 32 are mounted on the column 4. This type of installation is contrary to the conventional method. This method makes it difficult for the iron filings generated during processing to accumulate on the first Y-axis slide rail 31 and the second Y-axis slide rail 32, and it is also difficult to accumulate water, thereby effectively preventing The chipping and waterproofing improve the service life of the drilling and tapping center machine.

Referring to FIG. 2, FIG. 4 and FIG. 5, the column 4 includes a first column body 41 and a second column body 42. The first column body 41 is substantially a right-angled triangular column, and the bottom portion is provided for the first Y-axis slide rail 31 and the second Y-axis slide rail 32. The first pillar body 41 has a slanted connecting wall 411 , a sidewall 412 , and a first through hole 413 . The first pillar body 41 is viewed from a side view, and the long side is the inclined connecting wall 411, and the short side is the side wall 412. The first through hole 413 penetrates from the inclined connecting wall 411 to the side wall 412 . A plurality of outer reinforcing ribs 43 are disposed on opposite sides of the first column body 41, and the outer reinforcing ribs 43 are connected to the inclined connecting wall 411.

The second pillar body 42 extends outward from the inclined connecting wall 411 and is located slightly lower than the first through hole 413. The second column body 42 has an elongated column shape and a slightly truncated triangle in cross section, and a second through hole 421 is defined. The second through hole 421 extends through the second pillar body 42 and continues to penetrate from the inclined connecting wall 411 of the first pillar body 41 to the sidewall 412. The second through hole 421 is substantially parallel to the extending direction of the first through hole 413 and has a larger aperture than the first through hole 413. A plurality of inner reinforcing ribs 44 are disposed in the second through hole 421 and the first through hole 413.

A first Z-axis slide rail 45 and a second Z-axis slide rail 46 are mounted on the side wall 412 of the column 4. The first Z-axis slide 45 is connected to a spindle head 5 by a first Z-axis slider 48. The second Z-axis slide 46 is coupled to the spindle head 5 by a second Z-axis slider 49.

The column 4 is detachably connected to the spindle head 5. Since the column 4 itself is affected by the slider span of the Z-axis, it is necessary to satisfy the length of the displacement in the Z-axis direction, and the length of the side wall 412 of the first column body 41 has a certain limit, and further, during operation In order to facilitate the driving of the column 4, the weight of the column 4 is reduced by the design of the second through hole 421 and the first through hole 413, and the inner reinforcing ribs 44 are disposed therein to reduce the force. The outer ribs 43 are placed on the outside to increase the overall strength. Thus, without affecting the height of the side wall 412 and the strength of the column 4, the hollow design can effectively reduce the weight.

It is worth mentioning that the number of through holes can be one, or three or more, depending on the degree of weight reduction, and the position and number of inner reinforcing ribs 44 and outer reinforcing ribs 43 can also be made according to actual needs. The adjustment can also be confirmed by software calculation to measure the strength of the column 4.

Referring to FIG. 1, the first screw 6 is mounted between the base 2 and the saddle 3. The first screw 6 is sleeved with a first screw sleeve (not shown) that engages with the saddle 3. The rotation of the first screw 6 can drive the first screw sleeve to move into The base 2 is driven to be displaced relative to the saddle 3. The second screw 7 is mounted between the saddle 3 and the column 4, and the second screw 7 is sleeved with a second screw sleeve (not shown) that engages with the saddle 3. The rotation of the second screw 7 can drive the second screw sleeve to move, thereby driving the saddle 3 and the column 4 to be relatively displaced.

The carrier mechanism 8 is detachably mounted on the side wall 412 of the base 2. The carrier mechanism 8 includes a table 81 and a bracket 82. The bracket 82 is mounted to the mounting holes 212 of the body 21 through a plurality of fixing members. The table 81 is detachably disposed on the bracket 82. Since the mounting holes 212 are sequentially arranged from the bottom to the bottom, the user can select the mounting hole 212 at a suitable position according to the size of the workpiece to be processed to adjust the working table 222 and the spindle. The distance between the heads 14 to change the amount of space used to accommodate the workpiece. The fixing member of this embodiment is a screw.

It is worth mentioning that the position of the bearing mechanism 8 is lower than that of the linear slide rail in the X-axis direction, so that the cutting fluid is more difficult to be sprayed onto the first X-axis slide rail 22 and the first X-axis slide rail 24, It can avoid the occurrence of corrosion.

A water tank 9 is mounted outside the base 2, and the water tank 9 is located below the carrying mechanism 8. A water tank positioning groove 214 is defined in the base 2, and an edge of the water tank 9 can be inserted into the water tank positioning groove 214 to be installed in a card position.

Through the above description, the advantages of the present invention can be summarized as follows:

1. The bearing mechanism 8 of the present invention can adjust the bearing mechanism 8 on the mounting hole groups 211 according to the size of the workpiece. The position, in turn, adjusts the space between the spindle head 5 and the table 81 to accommodate workpieces of different sizes.

2. The water tank 9 is disposed below the support mechanism 8, so that the iron filings during processing can be directly carried by the cutting fluid, thereby improving the working efficiency and extending the maintenance period.

3. The position of the bearing mechanism 8 is lower than that of the linear slide rail in the X-axis direction, so that the cutting fluid is more difficult to be sprayed onto the first X-axis slide rail 22 and the first X-axis slide block 24, thereby avoiding corrosion. happened.

4. The conventional slide rail and the slider are installed by first installing the slide rail, then setting the slider thereon, and setting the object to be slid on the slider. The present invention installs the Y-axis in an inverted manner. The slide rails 31, 32 and the sliders 33, 34 in the direction, that is, the slide rails 31, 32 in the Y-axis direction are first mounted on the bottom of the column 4, and the Y-axis directions are further provided on the Y-axis slide rails 31, 32. The sliders 33, 34 are then engaged to the saddle 3 by the entirety of the uprights 4. Such a method of installing the linear slide rail in the Y-axis direction reversely causes the iron scraps generated during the processing to be less likely to accumulate on the first Y-axis slide rail 31 and the second Y-axis slide rail 32, and is also less likely to accumulate water. This can effectively prevent chipping and waterproofing, and improve the service life of the drilling and tapping center machine.

5. Through the design of the present invention, the user only needs to provide a shield on the slide rail and the slider on the X-axis, so that the cost of setting the shield can be saved.

6. The height difference between the first X-axis slide rail 22 and the second X-axis slide rail 23 is designed to bias the weight of the saddle 3, so when the saddle 3 is moved forward in the Y-axis direction , capable of balancing the column 4 and the spindle The weight of the head 5 can play a better balance.

7. The first through hole 413 and the second through hole 421 are opened on the column 4 to reduce the weight of the column 4 by setting the first and second through holes 421 without affecting the displacement distance of the Z axis. The ribs 43 and the inner ribs 44 are used to effectively increase the rigidity of the column 4.

[Second embodiment]

Referring to Figure 6, the second embodiment of the drilling and tapping center machine of the present invention is substantially the same as the first embodiment except that the carrier mechanism 8 is different.

The carrier mechanism 8 includes a set of A-axis 83 and a connecting plate 84. The connecting plate 84 is mounted on the mounting holes 212 of the body 21 through a plurality of fixing members. The A-axis 83 is detachably disposed on the connecting plate 84. The A-axis 83 is disposed on the connecting plate 84, which is rotatable about the X-axis, so that the workpiece carried thereon can also be rotated to rotate about the X-axis. The fixing member of this embodiment is a screw.

The A-axis mounting method in the conventional tapping machine is to longitudinally mount it on a table (not shown) located on the X-axis slide rail (not shown). Since the A-axis itself occupies a certain volume, the workpiece placed on the A-axis will be closer to the spindle head, that is, the space for accommodating the workpiece will be reduced, resulting in the ability to process only smaller-sized workpieces. The A-axis 83 of the present invention is laterally mounted on the side of the base 2 through the connecting plate 84, so that the vertical distance between the workpiece placed on the A-axis 83 and the spindle head 5 is constant, and thus the receiving space It will not change. Furthermore, the user can adjust the mounting position of the A-axis 83 downwards, so that the present invention can apply to the larger-sized workpiece. work.

In summary, the bearing mechanism 8 can adjust the position of the bearing mechanism 8 on the mounting hole group 211 according to the size of the workpiece, and then adjust the space that can be processed to accommodate workpieces of different sizes. It is indeed possible to achieve the object of the invention.

However, the above is only the embodiment of the present invention, and the scope of the present invention is not limited thereto, and the simple equivalent changes and modifications made by the scope of the patent application and the patent specification of the present invention are still Within the scope of the invention patent.
