Description
Technical field
The utility model belongs to the clamping tool for machine work technical field, particularly relates to a kind of fittings body dowel hole drilling tool.
Background technology
Along with manufacturing development, division of labor specialization, large-scale mass production, product parts lightness, powder metallurgy maturing, high-quality a large amount production capacity power have become the inexorable trend of development, requirement to part processing and manufacturing fixture used is also more and more higher, and fixture is the important frock that guarantees Workpiece Machining Accuracy and production efficiency.Fittings body is a kind of foundry goods that waters, and fittings body comprises centre bore and dowel hole, and the axis of centre bore and dowel hole is vertical, adds man-hour at the dowel hole of butt joint body, requires to guarantee the distance between dowel hole and centre bore.In conventional art, the method that the dowel hole of butt joint body carries out the machining employing is, fittings body is fixed by fixture, operating personnel determine the axial location of dowel hole on fittings body by line, utilize drill bit to get out dowel hole, in this processing mode, crossed process is complicated and consuming time, have a strong impact on the working (machining) efficiency of fittings body, and the positional precision of dowel hole is low.
Summary of the invention
The utility model is intended to solve the technical problems such as the fittings body dowel hole manufacturing procedure that exists in known technology is complicated, machining accuracy is low and a kind of simple in structure, easy to use, good positioning effect is provided, can improves Workpiece Machining Accuracy, improves the fittings body dowel hole drilling tool of workpiece working (machining) efficiency.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of fittings body dowel hole drilling tool, it is characterized in that: comprise the frock main body, described frock main body is provided with the locating shaft that coordinates with the fittings body centre bore, described frock main body is provided with bushing plate, described bushing plate is provided with the drill jig hole, described drill jig is equipped with drill bushing in the hole, the axis in described drill jig hole is vertical with the axis of described locating shaft, and described frock main body is provided with the hold-down mechanism be used to the body of clamping.
The utility model can also adopt following technical scheme:
Described hold-down mechanism comprises the pressing plate of the screw rod that is connected with described locating shaft, the described screw rod of suit and is fitted in locking nut on described screw rod.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, namely design a kind of special tooling of dowel hole of working joint body, this frock can easily be located fittings body, and can guarantee that fittings body has the dowel hole position machining accuracy of unified standard, remove the crossed process in conventional art from, can greatly improve the working (machining) efficiency of fittings body.Outside first, also have advantages of simple in structure, easy to use.
