Abstract

The invention discloses a drilling fixture for a crank positioning pin hole, which comprises a fixture body, a cylinder, an upright post, an upper tip, a positioning plate, a template, a drilling sleeve, a floating tip and a positioning pin. The drilling fixture realizes initial positioning by utilizing the matching between the outer end surface of a crank and the floating tip at the top end of the fixture body as well as the positioning pin; the cylinder in the fixture body is started to pull the upright post so as to realize the matching between the downward upper tip at the top end of the upright post and an upward central hole of the crank, thereby realizing axial positioning and clamping of the crank; and the crank positioning pin hole is accurately drilled according to the drilling sleeve on the template. With synchronous installing and positioning, synchronous positioning and compacting, good drilling quality, short auxiliary working hours and high production efficiency, the drilling fixture is particularly suitable for mass production and application.

Description

Drilling fixture for crank positioning pin hole
Technical field
The present invention relates to a kind of clamping tool for machine work, particularly a kind of boring grab.
Background technology
Crank is the main building block of bent axle, belongs to shaped piece.The crank inner face is provided with a dowel hole, this hole site required precision height, and the drilling difficulty of processing is big.Prior art adopts template and crank inner face location, is aided with shop bolt and only revolves, and the drill jig of this structure can be realized location processing, but can not accurately locate processing.The drill jig of this kind indirect addressing is difficult to satisfy the requirement of crank dowel hole drilling machining accuracy.
Summary of the invention
The present invention is primarily aimed at the deficiencies in the prior art, proposes that a kind of location structure is simple, accurate positioning, positioning and reliable clamping drilling fixture for crank positioning pin hole.These anchor clamps are bearing-surface with the crank large end face, and shop bolt only revolves, and centre bore location and clamping realize accurately location.
The present invention is achieved through the following technical solutions technical goal.
Drilling fixture for crank positioning pin hole, it comprises clamp body, cylinder, column, it is top to go up, location-plate, template, drill bushing, top and shop bolt floats.Described cylinder is built in the clamp body inner chamber of frame structure, and the column that cylinder connects upwards passes from clamp body top end face endoporus.Its improvements are: described column top is connected with the location-plate right-hand member, the location-plate left end that is horizontal boom is provided with down last top, be provided with up unsteady top and shop bolt at clamp body top end face left part, it is top and last top coaxial to float, the clamp body left side wall exceeds top end face and connects template towards right level, and the template right-hand member is provided with vertical drill bushing.
In the said structure, end surface supporting is rotated by the shop bolt and the crank hole engagement limits of prismatic on the clamp body top end face beyond the crank, and the top and last top acting in conjunction of floating makes crank axle to centering and clamping.
The present invention compared with prior art has following good effect:
1, cooperate with crank axial center hole and end-face hole with alignment pin, this location structure is simple, the positioning accuracy height;
2, location and clamping synchronization implementation are installed and are promptly put in place, and installation is few unproductive time;
3, drilling is easy to process, and charge and discharge operations is easy.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The invention will be further described with reference to the accompanying drawings below.
Drilling fixture for crank positioning pin hole shown in the drawings, it comprises clamp body 1, cylinder 2, column 3, it is top 4 to go up, location-plate 5, template 6, drill bushing 7, float top 8 and shop bolt 9.Clamp body 1 is the frame shape main component among the present invention, and clamp body 1 inner chamber is installed cylinder 2, and top end face is provided with unsteady top 8 and shop bolt 9 up, and left side wall exceeds top end face and connects template 6 towards right level, and template 6 right-hand members are provided with vertical drill bushing 7.Be located at cylinder 2 in clamp body 1 inner chamber and connect columns 3 and pass from clamp body 1 top face, column 3 tops are connected with location-plate 5 right-hand members, location-plate 5 left ends that are horizontal boom be provided with down last top 4.During practical application of the present invention, at first the outer face with crank is bearing on clamp body 1 top end face, cooperate with the crank end face by shop bolt 9, rotating crank then, top 8 cooperates with centre bore on the crank end face and to realize location just until floating, start the cylinder 2 downward columns 3 that spur, make to be located at column 3 tops last top 4 cooperating down with crank centre bore up, realize crank axial location and clamping, by the drill bushing 7 accurate drilling crank dowel holes on the template 6.The present invention installs i.e. location, locatees and compress synchronous realization, and the drilling quality is good, and unproductive time is few, the production efficiency height.
