Description

Drilling and tapping center machine

The present invention relates to a processing machine, and more particularly to a drilling and tapping center machine.

Drilling and tapping center machine is a metal cutting machine tool and also a digital control processing equipment. Its style and function are similar to those of the machining center. However, because the spindle adopts a lower inertia design, the spindle has higher stability under operation, and the tool change of the clamp arm magazine is faster and more accurate, and the tool change time is higher. Short, and easy to operate, etc., is therefore widely used in the industry.

However, the cutting device of the drilling and tapping center machine currently used in the market is easy to accumulate iron scraps and cutting fluid on the linear slide rail in the Y-axis during the machining process, which not only affects the smoothness and accumulation of the slip. The cutting fluid is also prone to corrosion, resulting in a reduced service life of the drilling and tapping center machine, which has an improved need.

Therefore, the object of the present invention is to provide a drilling and tapping center machine which can effectively prevent water and debris and improve the service life.

Therefore, the novel drilling and tapping center machine comprises a sliding device and a processing device.

The sliding device includes a base, a saddle, and at least one Y-axis rail set. Each Y-axis rail set has a Y-axis slider disposed at the top of the saddle and a Y-axis slide rail disposed on the slider.

The processing device is disposed on the Y-axis slide of the Y-axis rail set for machining the workpiece.

The effect of the new model: the traditional way of installing the slide rail and the slider is to install the slide rail first, then set the slider thereon, and set the object to be slid on the slider, the new type is reversed. The Y-axis rail set is mounted, that is, the Y-axis slide rails are first mounted on the processing device, and then the Y-axis slides are snapped onto the saddle. This reverse installation method will make it difficult for the iron filings generated during processing to accumulate in the Y-axis rail group, and it is also difficult to accumulate water, which can effectively prevent chipping and waterproofing, and improve the service life of the drilling and tapping center machine.

The mounting hole groups 42 are respectively formed on the support columns 41, and thus are also formed on the same side of the body 211 of the base 21, and each mounting hole group 42 has five mounting holes arranged in order from the bottom to the bottom. 421. The distance between two adjacent mounting holes 421 in each mounting hole group 42 is 70 to 80 mm. It should be noted that the number of the mounting holes 421 can be adjusted as long as there are at least two mounting holes 421 in each mounting hole group 42, and the highest and lowest installations can be adjusted according to requirements. The distance between the holes 421 is between 100 and 300 mm, and within this distance, the user can also open the mounting holes 421 as needed, or can not be opened separately. Therefore, the number of the mounting holes 421 can be It can be two to four, and it can be six or more.

The carrier mechanism 43 is disposed in the mounting hole set 42 for carrying the workpiece so that the workpiece can be processed by the spindle head 33. The carrier mechanism 43 includes a bracket 431 and a table 432. The bracket 431 is generally L-shaped from the side, wherein one side is disposed on the mounting hole group 42 through a plurality of screws, and the other side allows the table 432 to be disposed. The table 432 is movable along the X-axis on the bracket 431 and is positioned lower than the X-axis rail sets 22, so that the cutting fluid is less likely to splash and corrode the X-axis rail sets 22.

Referring to FIG. 1 and FIG. 4 , the water tank 5 is disposed under the supporting mechanism 43 , and the top edge thereof is disposed on the positioning groove 213 of the base 21 . The length and width of the water tank 5 are larger than the table 432 so that the cutting fluid can Iron filings are brought into the water tank 5, wherein the water tank 5 is of sufficient length to cover the extent to which the table 432 slides. In the present embodiment, the width of the water tank 5 is about twice the width of the table 432, and the side edges are aligned with the support columns 41 when mounted to the positioning groove 213.

Referring to FIGS. 1 and 2, the driving device 6 is disposed between the body 211 and the saddle 23, and includes an X-axis screw 611 group 61, a Y-axis screw group 62, and a Z-axis screw group 63. The X-axis screw 611 group 61 is used to drive the saddle 23 to move along the X-axis and has an X-axis screw 611 and an X-axis threaded sleeve 612. The X-axis screw 611 is disposed on the screw groove 212 of the base 21, and the X-axis threaded sleeve 612 is disposed on the bottom surface 231 of the saddle 23. The Y-axis screw set 62 is disposed between the saddle 23 and the upright 31 for driving the saddle 23 to move in the Y-axis direction. The Z-axis screw set 63 is disposed between the column 31 and the spindle head 33 for driving the spindle head 33 to move in the Z-axis direction. After the workpiece is placed, the user can operate the saddle 23, the column 31 through the driving device 6, and the spindle head 33 moves in the X, Y, and Z axis directions, respectively, so that the spindle head 33 can reach the predetermined position.
