Description

A kind of self-centering Boring machine school knife rest
Technical field
The utility model relates to machining manufacturing technology field, specifically is meant a kind of self-centering Boring machine school knife rest.
Background technology
In the shipbuilding or other manufacturing industry of convention, usually need utilize Boring machine that large-sized structural parts is carried out bore hole, as carrying out bore hole to the inner hole of bearing seat of screw shaft of ship or to the endoporus of rudder stock seat.As shown in Figure 1; The boring bar 201 of Boring machine is a round bar; Tool holder body 301 be one be set on the boring bar 201 and can slide along boring bar 201 front and back columnar structured; Knife rest head 302 is for being fixed on the box-structure in tool holder body 301 outsides, and bolt 303 fixing and lockings that boring cutter 304 passes through the end are on knife rest head 302.The radius of required machining hole is the distance into point of a knife 305 to boring bar 201 centers; This distance can be decomposed into boring bar 201 radius r and point of a knife 305 to boring bar 201 outer rims apart from the d sum; But; Owing to there is the knife rest head 302 of tool holder body 301 cylindraceous and box between point of a knife 305 and the boring bar 201, have the influence that intercepts to measuring, so can't directly measure from point of a knife 305 to boring bar 2 outer rims apart from d; If directly measure not only operation inconvenience with existing chi, rule class measurer, and the precision of measuring is lower; So in actual process; The a bit of endoporus of examination boring is as measuring section earlier; Through the apertometer of measuring examination boring section calculate point of a knife to boring bar outer rim apart from d, promptly be equivalent to measure two distances between the concentric circles, but this measuring method is had relatively high expectations to operators'skills; And the examination boring need take more man-hour with the adjustment boring cutter, has reduced production efficiency.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of self-centering Boring machine school knife rest that can confirm the bore hole internal diameter size easily is provided.
The utility model is realized through following technical scheme, mainly comprises footstock, positioning bar, seat bar, round bar chi, elastic component, fixed head, gage beam and positioning nut;
Said footstock bottom is provided with can be at the self-centering V-type groove of boring bar outer rim, and footstock inside has elastomeric element;
Said positioning bar is installed on the footstock with the bottom of seat bar, after fixed head is passed on the top, is fixed plate through nut and fixes;
Said round bar chi with scale wears and is installed in the footstock, and is fixed on the elastomeric element, and fixed head is passed on round bar chi top, and the bottom is located in the V-type groove, and elastomeric element offers the downward elastic force of round bar chi;
Said gage beam is sleeved on positioning bar, seat bar and the round bar chi, and can be arranged on the positioning bar and two adjusting nuts that lay respectively at the gage beam above and below through rotation, and the control survey arm is along adjusting rod axial adjustment and fixing.
The bottom surface of said gage beam is a measurement face.
Said elastomeric element is the spring of band spring base.
The advantage of the utility model is, 1. can measure the distance of point of a knife to boring bar outer rim easily, the fixed position of sizing tool, thus confirm the bore hole internal diameter size; 2. certainty of measurement is high; 3. convenient to operation, practiced thrift man-hour, improved production efficiency; 4. in light weight, to make simple and easyly, cost is low.
Description of drawings
Fig. 1 is the sketch map of prior art;
Fig. 2 is one of structural representation;
Fig. 3 is two of a structural representation;
Fig. 4 is the user mode sketch map.
The specific embodiment
Preferred embodiment below in conjunction with 2 to 4 pairs of the utility model of accompanying drawing is described further, and mainly comprises footstock 1, positioning bar 2, seat bar 3, round bar chi 4, elastic component 5, fixed head 8, gage beam 7 and positioning nut 6;
Said footstock 1 bottom is provided with can be at the self-centering V-type groove 11 of boring bar 201 outer rims, and footstock 1 inside has elastomeric element 5;
Said positioning bar 2 is installed on the footstock 1 with the bottom of seat bar 3, after fixed head 8 is passed on the top, is fixed plate 8 through nut 9 and fixes;
Said round bar chi 4 with scale wears and is installed in the footstock 1, and is fixed on the elastomeric element 5, and fixed head 8 is passed on round bar chi 4 tops, and the bottom is located in the V-type groove 11, and elastomeric element 5 offers the downward elastic force of round bar chi 4;
Said gage beam 7 is sleeved on positioning bar 2, seat bar 3 and the round bar chi 4, and can be arranged on the positioning bar 2 and two adjusting nuts 6 that lay respectively at gage beam 7 above and belows through rotation, and control survey arm 7 is along adjusting rod 2 axial adjustment and fixing.
The bottom surface of said gage beam 7 is a measurement face.
Said elastomeric element 5 is the spring of band spring base.
During use; Earlier with the bottom of footstock 1 vertically by being located on the boring bar 201; Because the footstock bottom is provided with the self-centering structure of V-type groove 11; Therefore the center line of the positioning bar 2 on the footstock 1, seat bar 3 and round bar chi 4 is all perpendicular to the center line of boring bar 201, and the measurement face of gage beam 7 is parallel with boring bar 4; And under the effect of the elastomeric element 5 of being with spring base, the bottom end face of round bar chi 4 is close to the outer rim of boring bar 201, and then the scale of the measurement face of gage beam 7 on round bar chi 4 is the distance of measurement face to boring bar 201 outer rims.Again according to the bore size requirement of drawing requirement; Regulate the position of gage beam 7 through rotation positioning nut 6; Make the measurement face scale and the boring bar 201 radius sums of gage beam 7 equal required bore hole processing radius, locking positioning nut 6 makes gage beam 7 location, the point of a knife 305 of boring cutter 304 is tightly propped up the measurement face of gage beam 7; Clamping screw 303 is promptly accomplished the installation site of boring cutter 304 and the correction of processing radius fast, easily.
