Abstract
The invention relates to a positioning die for machining a screw hole of a top-mounted valve body base. The positioning die can be used for the positioning machining of the screw hole in a flange of the top-mounted valve body base. The positioning die is characterized by comprising a template which is an equiangular hexagon. A cylindrical lug boss concentric with the template is arranged on the upper surface of the template. A round hole is formed in the central position of the lug boss, and penetrates through the template. Six positioning holes are symmetrically distributed outside the lug boss in the template, each positioning hole is opposite to a corner of the hexagonal template, and the center connecting line of every two opposite positioning holes passes through the center of the template. The die is used for the positioning machining of the screw hole of the top-mounted valve body base, so that the machining accuracy can be improved, and the reject rate can be reduced; and moreover, the positioning die is simpler and low in investment cost.
Description
Technical field
The present invention relates to a kind of valve body processing jig, is the positioning and guiding mould that is used for processing the screw hole on the roof-mounted valve base ring flange specifically.
Background technology
At present at mechanical processing industry; Screw to roof-mounted valve base adds man-hour; The main method that adopts is that roof-mounted valve body directly is fixed on the drilling machine machine table; The valve body bottom surface upwards utilizes drill bit on roof-mounted valve base, to get out screw again, and the position of screw needs operating personnel manually or through survey tool to be labeled on the valve base in advance.Yet, operating personnel when carrying out bore operation because vision or operate miss, the position that tends to make the screw misalignment that machines to mark in advance, thereby cause machining accuracy not enough, percent defective is higher.And to this problem, main improvement scheme of the prior art is a mounting positioning on drilling machine, and this navigation system need import control program in advance, marches to the exact position through control program driving drill bit and carries out bore operation.This improvement is comparatively complicated, and has increased the input cost of equipment greatly.
Summary of the invention
The problem that the present invention will solve provides a kind of roof-mounted valve base screw processing and uses jig.Adopt this mould that roof-mounted valve base screw is positioned processing, not only can improve machining accuracy, the rate of reducing the number of rejects and seconds, and also comparatively simple, input cost is low.
For addressing the above problem, the present invention takes following technical scheme:
Roof-mounted valve base screw processing of the present invention is to comprise template with the jig characteristics, and template is the isogonism hexagon, and wherein two relative edge lengths are equal and greater than other four limits.The upper surface of said template has the cylindrical boss concentric with it, and the centre bit of boss is equipped with circular hole, and circular hole runs through template.Six locating holes that symmetrical distribution is arranged outside boss on the said template; Locating hole be through hole and its axis all with template on the parallel axes of circular hole; An angle of all corresponding hexagon template of each locating hole, and the line of centres of two relative locating holes is through template center.
Take such scheme, have the following advantages:
Can find out by such scheme; Because roof-mounted valve base screw processing of the present invention has locating hole with jig on the correspondence position at each angle of hexagon template; In that being carried out screw, roof-mounted valve base adds man-hour; Through locating hole the screwhole position of valve base is carried out pre-determined bit, drill bit only need pass locating hole can process screw accurately on valve base.Like this, not only can improve machining accuracy, the rate of reducing the number of rejects and seconds, and also the improvement method is comparatively simple, and the cost of input is lower.
Description of drawings
Fig. 1 is the structural representation of roof-mounted valve base screw processing of the present invention with jig;
Fig. 2 be among Fig. 1 A-A to cutaway view.
The specific embodiment
As depicted in figs. 1 and 2, roof-mounted valve base screw processing of the present invention comprises template 1 with jig, and template 1 be the isogonism hexagon, and wherein two relative edge lengths are equal and greater than other four limits.The upper surface of said template 1 has the cylindrical boss concentric with it 3, and the centre bit of boss 3 is equipped with circular hole 2, and circular hole 2 runs through template 1.Six locating holes 4 that symmetrical distribution is arranged in boss 3 outsides on the said template 1; Locating hole 4 be through hole and its axis all with template on the parallel axes of circular hole 2; An angle of all corresponding hexagon template 1 of each locating hole 4, and the line of centres of two relative locating holes 4 is through template 1 center.
During operation; At first roof-mounted valve base is fixed on the drilling machine; Upwards insert roof-mounted valve base screw processing of the present invention in the circular hole of valve bases with the boss on the jig template 3 the valve body bottom surface again, and the circular hole of boss 3 and valve base is and closely cooperates at this moment; Utilize drill bit on the drilling machine to stretch into locating hole 4 on the template then, carry out screw processing to valve base.
