In mechanical processing industry, boring refers to processes the operation of portalling on solid material with drill bit.Polygon base 1 as shown in Figure 1, according to production requirement, need to process through hole 101 to its four bights, because the structure of this polygon base 1 is comparatively complicated, and its bottom is with round boss 102, the interior circular hole (not shown in figure 1) with concentric layout also in round boss 102, therefore traditional frock clamp cannot be realized its location and accurately process, must use special positioning fixture to meet the machining accuracy of boring.Utility model content
The applicant, for above-mentioned existing issue, is studied improvement, and a kind of hole drilling positioning fixture is provided, and it is simple in structure, accurate positioning, and machining accuracy is high.
The technical scheme that the utility model adopts is as follows:
A kind of hole drilling positioning fixture, comprises base, and installation base and slippage slot are set respectively on base, is positioned at the periphery of installation base, is also symmetrical arranged alignment pin and has multiple the first through holes on base; One end of fixed head and base is affixed, and screw rod runs through described fixed head and is threaded with slide block, and described slide block is rabbeted in described slippage slot.
Its further technical scheme is:
Described slide block comprises dovetails, in described dovetails, to external symmetry, extends abutting part, forms " V " shape opening between two abutting parts, and resilient key is also set on described abutting part;
Fixed head is "T"-shaped;
Locating cover is also set on described base, the locating hole that has multiple the second through holes and be arranged symmetrically with on described locating cover, the circle centre position that is positioned at described locating cover also has the installing hole connecting for locking nut;
Described locating cover is circular;
Described base has a round nose, and the diameter of described round nose is identical with the diameter of locating cover.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, easy for installation, slippage by screw drive slide block in slippage slot, and by resilient key, realized the accurate location to Assembly of the parts, the layout of locating cover has guaranteed the solid stability of part in process, has greatly improved machining accuracy and working (machining) efficiency.
