Abstract
The utility model discloses a drilling machine tool rest for processing a large hole, which comprises a tool bar and is characterized in that the tool bar is also fixedly connected with a tool apron; the tool apron is provided with a tool groove and a screw hole for fixing a tool; the tool bar on the lower part of the tool apron is also provided with a guide sleeve; the upper end of the tool apron is also provided with a fixed sleeve; and the outer diameter of the fixed sleeve is greater than the that of the guide sleeve. The drilling machine tool rest for processing the large hole has the advantages of high processing accuracy and high efficiency.
Description
Technical field
The utility model relates to a kind of drilling machine knife rest, is used to process the drilling machine knife rest of macropore.
Background technology
Process circular hole at present on equipment such as large-sized boiler, the volute drill bit that common driller uses only is suitable for during less than 136mm in the aperture, and aperture senior general again can't process; It is long to use boring machine processing then to take the cycle, can not guarantee ordinary production, and the cost height.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of drilling machine knife rest that is used to process macropore is provided, and it has the high and high advantage of efficient of machining accuracy.
For achieving the above object, the drilling machine knife rest that is used to process macropore of the present utility model comprises knife bar, it is characterized in that also being fixedly connected with tool rest on knife bar, is provided with the screw of cutter groove and fixed cutting tool on tool rest; Guide pin bushing also is housed on the knife bar below the tool rest, in the upper end of tool rest fixed cover is housed also, the external diameter of fixed cover is greater than the external diameter of guide pin bushing.
During use, stage properties such as white steel knife are loaded in the cutter groove, and lock by bolt; In the process that knife bar descends, the guide pin bushing of below is introduced in the bottom outlet to be expanded and leads, and cutter descends gradually bottom outlet is carried out reaming, and when guide pin bushing shifted out in the hole, fixed cover entered and continues guiding in the hole, can guarantee machining accuracy, and the efficient height;
As further improvement of the utility model, be provided with screw thread in the lower end of knife bar, guide pin bushing is loaded on the knife bar by positioning sleeve and nut; Fixed cover is loaded on the upper end of tool rest by bolt; Be convenient to change guide pin bushing and fixed cover, with the circular hole of processing different size, versatility is good;
In sum, the utlity model has the high and high advantage of efficient of machining accuracy, and versatility is good.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
By shown in Figure 1, the drilling machine knife rest that this is used to process macropore comprises knife bar 1, and also welding is fixedly connected with tool rest 2 on knife bar 1, is provided with the screw 2b of cutter groove 2a and fixed cutting tool on tool rest 2; Be provided with screw thread on the knife bar below the tool rest 21, by positioning sleeve 3 and nut 4 guide pin bushing 5 be housed also on the knife bar below the tool rest 21, by bolt fixed cover 6 is housed also in the upper end of tool rest 2, the external diameter of fixed cover 6 is greater than the external diameter of guide pin bushing 5.
During use, stage properties such as white steel knife are loaded among the cutter groove 2a, and lock by bolt; In the process that knife bar 1 descends, the guide pin bushing 5 of below is introduced in the bottom outlet to be expanded and leads, and cutter descends gradually bottom outlet is carried out reaming, and when guide pin bushing 5 shifted out in the hole, fixed cover 6 entered and continues guiding in the hole, can guarantee machining accuracy, and the efficient height.
