Abstract
The invention discloses a special drilling fixture, which belongs to a drilling device, and particularly relates to a device for fixing a workpiece when symmetric holes are drilled in the upper surface and the lower surface of a hollow rotary body. The special drilling fixture is characterized in that a positioning disc which is installed through a bearing is arranged on the front side of a vertical plate of an inverted T-shaped supporting seat, a positioning disc shaft is installed in the bearing, the middle part of a positioning disc core is provided with a positioning disc opening, a chassis of the positioning disc is provided with positioning holes which are symmetric about the central line of the positioning disc opening, two opening pressure plate fixing bolts for fixing an opening pressure plate are installed on the front end of the positioning disc core, the periphery of the positioning disc is provided with three pressure plates which are uniformly distributed, the top of the supporting seat vertical plate is provided with a drilling template, the rear side of the supporting seat vertical plate is provided with a positioning pin system, and a positioning pin penetrates through the supporting seat vertical plate to enter the positioning holes. By utilizing the positioning disc to be matched with the positioning pin for positioning, the accuracy in positioning can be guaranteed; by utilizing an ordinary drill bit, not only is the cost low, but also the precision is improved, and the machining qualification rate is increased from the original 50 percent to 97 percent.
Description
Technical field
The invention belongs to rig, the equipment of fixation workpiece while particularly the upper and lower surface of hollow rotary body being bored to symmetrical holes.
Background technology
In machining, usually need the upper and lower surface of hollow rotary body to bore symmetrical hole, for example a kind of valve body of butterfly type check-valves just need to descend two sides respectively to bore two holes thereon, existing frock is that two set bolts are installed on inverted T-shaped bearing, use strap that work is clamped, then use lengthening drill bit to be once drilled to from top to bottom.This method axiality and center are high unstable, and holing, qualification rate is low only reaches 50%.Lengthening drill bit when rotation whipping is severe, and drill bit is not easy by drill bushing below, and drill bit easily fractures, though by after also can cause the hole dimension that bores defective below, upper and lower two sides' hole size differs.Drawback: drill bit cost is high, at the bottom of passing rate of processing, during assembling, bearing pin is installed difficulty.
Summary of the invention
In order to overcome the deficiency that existing use long drill bit processing cost is high, qualification rate is low, the invention provides a kind of Special drill frock, this kind of Special drill frock not only can be used common drill bit, and machining accuracy is expensive low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Special drill frock, it is characterized in that: the positioning disk that uses bearing to install is housed in the riser front side of inverted T-shaped bearing, positioning disk axle is arranged in bearing, the middle part of positioning disk core has positioning disk opening, the chassis of positioning disk is provided with take positioning disk open centre line as symmetrical locating hole, positioning disk core front end is equipped with the opening pressing plate set bolt of two permanent opening pressing plates, positioning disk periphery is equipped with equally distributed three block pressur plates, bushing plate is equipped with at the top of bearing riser, the rear side of bearing riser is equipped with alignment pin system, alignment pin penetrates locating hole through bearing riser.
Described alignment pin system comprise be fixed on bearing riser rear side location key seat, the positioning pin rod that is positioned at location key seat is equipped with spring spring at front end outward alignment pin handle can be housed on positioning pin rod termination on alignment pin boss, and the conical head of alignment pin front end penetrates in the locating hole on positioning disk chassis through bearing riser.
Described bushing plate is fixed on bearing riser top by bushing plate set bolt, and bushing plate is provided with drill jig hole.
Using method of the present invention is that workpiece is arranged on positioning disk and uses opening pressing plate to compress as shown in Figure 3, use drill bit by two holes of bushing plate spitting drill top, after having bored, pull alignment pin handle to make alignment pin release locating hole, rotation positioning disk 180 is spent to alignment pin and is penetrated new locating hole, use drill bit by bushing plate location, to be got out two holes of an other side, discharging.
The invention has the beneficial effects as follows due to use locating hole on positioning disk and alignment pin to cooperatively interact to locate guaranteed workpiece along with the accurate location of positioning disk Rotate 180 degree in addition on bushing plate the location of bushing plate can guarantee accurate positioning, because each two holes of only boring one side can be used common drill bit to there will not be drill bit whipping, not only reduced costs but also improved precision, testing factually former passing rate of processing is 50%, and after use the present invention, passing rate of processing brings up to 97%.
