On above-mentioned boring cutter bar, also be provided with gathering sill, and the holding screw that can inject in the gathering sill is housed on tool rest.
Put in above-mentioned adjustment big locking nut is housed, little locking nut is housed on boring cutter bar.
On adjustment cover, big locking nut and little locking nut, be provided with the circular hole that is convenient to rotate usefulness.
On the circumference of the nose circle cylinder that above-mentioned adjustment is overlapped, also be evenly distributed with scale.
The above-mentioned quantity that is evenly distributed on the scale lattice on the adjustment cover nose circle cylinder circumference is 50.
Owing to adopted technique scheme, the utility model by rotating the depth of cut that adjustment cover or boring cutter bar can be regulated boring cutter easily, is realized the trace adjustment of boring cutter in use, has made things convenient for tool setting and has improved the accuracy of tool setting.Therefore, the utility model compared with prior art, the advantage that the utility model not only has can be easily and fast, adjust the depth of cut of boring cutter exactly, but also have simple in structure, install and operation advantage easily all.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: structural representation of the present utility model as shown in Figure 1, a kind of device of adjusting the boring cutter depth of cut of the present utility model comprises tool rest 1, tool rest 1 is made as sleeve-shaped, and in tool rest 1, make a larger diameter internal bore and a minor diameter endoporus, the larger diameter internal bore of tool rest 1 is made as screwed hole, its minor diameter endoporus is made as smooth hole, in the larger diameter internal bore of tool rest 1, install adjustment cover 4 by the mode that is threaded, and be used for the bolt 2 that is connected with boring tool holder on the conventional boring machine knife bar installing on the tool rest 1, the endoporus of adjusting cover 4 also is made into screwed hole, adjusting the internal thread pitch and the external screw thread pitch of cover 4 can determine according to the needs that use, generally speaking, for the ease of regulating, its thread pitch can be made into 1～2 millimeter pitch (pitch that will adjust the internal thread of cover 4 in the present embodiment is made as 1.5 millimeters, and the external screw thread pitch of adjusting cover 4 is made as 2 millimeters); In the endoporus of adjusting cover 4, install boring cutter bar 5 then, with boring cutter bar 5 by the mode that is threaded
Tail end is made into the polished rod structure, and the polished rod of boring cutter bar 5 tail ends can be inserted in the minor diameter endoporus of tool rest 1 movingly, produces a square hole that boring cutter 9 can be installed at the front end of boring cutter bar 5, and on boring cutter bar 5 two jackscrews 7 that are used to lock boring cutter 9 is installed; In order to regulate and to lock more reliably, can on boring cutter bar 5, make a gathering sill 10, and on tool rest 1, the holding screw 3 that can inject in the gathering sill 10 is installed; Adjusting big locking nut 6 of installation on the cover 4, a little locking nut 8 is installed on boring cutter bar 5 simultaneously; Convenient in order to regulate, can on adjustment cover 4, big locking nut 6 and little locking nut 8, produce the circular hole 11 that is convenient to rotate usefulness; To observe in order being convenient to when regulating, can to produce scale by equally distributed mode on the circumference of the nose circle cylinder of adjusting cover 4, the quantity that generally speaking this is evenly distributed on the scale on the adjustment cover 4 nose circle cylinder circumference is made as 50 and gets final product.
Below using method of the present utility model and operation principle are further described:
Tighten little locking nut 8, adjustment this moment cover 4, big boring cutter bar 5 just become as a whole.Unclamp big locking nut 6, from the gathering sill 10 of boring cutter bar 5 lower ends, screw out holding screw 3, rotate and adjust cover 4, whenever circle, boring cutter 9 just can move a pitch 2mm inwards or outwards according to direction of rotation, rotate the integer circle during use as far as possible, guarantee that the cutting edge direction of boring cutter is constant.Tighten big locking nut 6 and holding screw 3 after adjusting, just can use processing.
If tighten big locking nut 6, just adjustment cover 4, tool rest 1 become as a whole at this moment.Unclamp little locking nut 8, from boring cutter bar 5 lower end gathering sills 10, screw out holding screw 3, rotate boring cutter bar 5, whenever circle, boring cutter 9 just can move a pitch 1.5mm inwards or outwards according to direction of rotation, rotate the integer circle during use as far as possible, guarantee that the cutting edge direction of boring cutter is constant.Tighten little locking nut 8 and holding screw 3 after adjusting, just can use processing.
If unclamp big locking nut 6 and little locking nut 8, holding screw 3 is screwed in the gathering sill 10 of boring cutter bar 5 lower ends, this moment, boring cutter bar 5 can only move axially along adjusting cover 4, and can not rotate, adjust cover 4 and rotate outside mobile 2mm of a week, and the mobile inwards 1.5mm of boring cutter bar 5 has realized the differential feed of boring cutter 9, and in fact 9 of boring cutters have outwards moved 0.5 mm.Therefore, the depth of cut that can be is according to actual needs rotated the depth of cut that corresponding angle can reach expection.Owing to adjust on the cover 4 end circumference 50 equally distributed scales arranged, revolution moves a scale, boring cutter 9 outwards move 0.01 mm(rotate round about then can move inward 0.01mm), thereby can realize the trace adjustment of boring cutter, made things convenient for tool setting and improved the accuracy of tool setting.After adjusting to needed size, tighten big locking nut 6 and little locking nut 8, hold out against holding screw 3 and just can carry out bore hole processing.
