Description
Technical field
The present invention relates to machining tool technical field, relate to a kind of boring reamer of the hole larger for finished diameter in particular.
Background technology
At present, the cutter that the fine finishining in hole uses is generally reamer, and the cutter used compared with the fine finishining of macropore is generally boring cutter.Use the advantage of reamer machining hole to be that the surface roughness in hole, circularity are all relatively good, but its shortcoming is also obvious, namely position degree affects larger by last process; The advantage using boring cutter machining hole to revise the site error of last process, and position degree is higher, but its shortcoming also clearly, and namely the circularity in hole, surface roughness are poor.
Summary of the invention
In order to overcome above-mentioned defect of the prior art, the invention provides a kind of boring reamer for improving the larger hole fine finishining precision of diameter, this boring reamer both can ensure surface roughness, the circularity in hole, also can ensure its positional precision.
The present invention adopts following technical scheme to realize above-mentioned purpose: a kind of boring reamer, be arranged on boring head, include straight sword reamer and boring cutter, this boring cutter is arranged in the cutter groove of this reamer vertically, and the tactical diameter of the point of a knife of this boring cutter 0.05 ~ 0.10mm less of the maximum gauge of reamer diametrically, the front end face of this boring cutter protrudes from the front end face 0.10 ~ 0.20mm of reamer in the axial direction.
Further illustrating as such scheme:
Preferably, described reamer rear end is provided with flange, this flange is provided with the boring cutter mounting groove corresponding with cutter groove, and the knife bar of described boring cutter is arranged in this boring cutter mounting groove along cutter groove, and be diametrically respectively equipped with tangential direction on this flange for fixing boring cutter knife bar mark closely screw.
Preferably, the tail end of the knife bar of described boring cutter is provided with domatic, and described flange is diametrically also provided with adjusting bolt, and the tail end of this adjusting bolt is provided with taper surface, the domatic corresponding matching of this taper surface and knife bar tail end, in order to regulating boring cutter in the axial direction with the relative position of reamer.
Preferably, described flange is provided with keyway and screwed hole, and this flange is connected and fixed by key connection and bolt and is connected on boring head.
Preferably, described reamer is hollow reamer, and the endoporus of this reamer and the axle of boring head adopt H6/h5 to coordinate to connect.
Preferably, described flange is also provided with the dismounting screwed hole for making reamer be separated with boring head.
Preferably, the key that described key connects is provided with screwed hole and the fastening bolt for this key fastening along flange diameter direction.
The beneficial effect that the present invention adopts above technical scheme to reach is: the boring cutter part of boring reamer of the present invention can play correcting action to the position in hole and remove most allowance, ensure that the uniformity of reamer allowance simultaneously, and then carry out little surplus cutting and extrusion process by reamer part, so both can ensure surface roughness, the circularity in hole, also can ensure its positional precision.

Detailed description of the invention
For setting forth 26S Proteasome Structure and Function of the present invention further, below in conjunction with accompanying drawing and preferred embodiment, the present invention is elaborated, but be to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Fig. 1 is the cross-sectional schematic of boring reamer of the present invention, Fig. 2 is that schematic diagram is looked on a left side of Fig. 1, as shown in FIG., boring reamer of the present invention is arranged on boring head 10, include straight sword reamer 1 and boring cutter 2, this boring cutter 2 is arranged in the cutter groove of this reamer 1 vertically, and the tactical diameter of the point of a knife of this boring cutter 2 0.05 ~ 0.10mm less of the maximum gauge of reamer 1 diametrically, the front end face of this boring cutter 2 protrudes from the front end face 0.10 ~ 0.20mm of reamer 1 in the axial direction, to ensure the machining accuracy of workpiece 3.Described reamer 1 is hollow reamer, its rear end is provided with flange 4, this flange 4 is provided with boring cutter 2 mounting groove corresponding with cutter groove, the knife bar of described boring cutter 2 is arranged in this boring cutter mounting groove along cutter groove, and on this flange 4, be diametrically respectively equipped with screwed hole and first with tangential direction mark closely screw 5 and second and mark closely screw 6, for the knife bar of fixing boring cutter 2, the tail end of the knife bar of this boring cutter 2 is provided with domatic, described flange 4 is diametrically also provided with screwed hole and adjusting bolt 7, the tail end of this adjusting bolt 7 is provided with taper surface, the domatic corresponding matching of this taper surface and knife bar tail end, in order to regulating boring cutter 2 in the axial direction with the relative position of reamer 1.Flange 4 is also provided with flat key keyway and screwed hole vertically, make flange 4 by key connect and bolt be connected and fixed be connected to boring head 10 end face on, and this flat key 9 is provided with screwed hole and fastening bolt 8 along flange 4 diametric(al), for flat key 9 is fixed on flange 4, the endoporus 13 of reamer 1 adopts H6/h5 to coordinate with the axle of boring head 10 to connect, to increase connection precision.Flange 4 is also provided with dismounting screwed hole 12, when boring reamer of the present invention disassembles from boring head 10 by needs, after pulling down the bolt 11 that flange 4 is connected with boring head 10, the bolt screwin that only one need be mated with this dismounting screwed hole 12, make bolt end withstand on boring head 10 end face, boring reamer of the present invention can be pressed down.
