Description

Bore the fixture of connecting rod small end hole
Technical field
The utility model relates to a kind of boring grab, is used for boring the hole in small end of connecting rod.
Background technology
Usually before boring the hole on small end of connecting rod, with small end of connecting rod cylindrical for benchmark, the end face of small end of connecting rod manually draw during the microcephaly of cross hairs to connecting rod look for, then connecting rod is clamped, drill bit on radial drilling machine is aimed at the mid point boring of cross hairs, such boring method more complicated, operating efficiency is not high.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of fixture boring connecting rod small end hole, and this fixture has the function of centralized positioning to connecting rod small end hole, clamping, can improve the operating efficiency of boring connecting rod small end hole.
The fixture of this brill connecting rod small end hole comprises the substrate 1 be fixed on Drilling machines bench, substrate is horizontal L shape, be made up of with vertical plate horizontal plate, the horizontal plate of substrate is provided with the bracket 2 of Π font, bracket is made up of one block of supporting plate and two pieces of frame plates, the bottom of frame plate and the horizontal plate of substrate are affixed, the little end surface of connecting rod 14 held by the supporting plate of bracket, the supporting plate being positioned at the small end of connecting rod left side is fixed with the first chuck 3, the vertical plate of substrate is rotary with screw rod 5, one end of screw rod props up the frame plate on the bracket left side, the vertical plate of substrate is also fixedly installed columniform guide post 6, one end of guide post is passed from the frame plate on the bracket left side, it is characterized in that, the horizontal plate of substrate is also fixedly connected with support 10, Rocker arm 4 is connected on support by mandrel 9, the top 7 be located on the frame plate on the right of bracket props up one end of rocking arm, the other end of rocking arm is provided with the second chuck 41, first chuck and the second chuck are provided with V-shaped groove, the groove face of V-shaped groove can contact with the excircle part of small end of connecting rod, rotating screw bolt can make the first chuck and the second chuck in opposite directions synchronizing moving small end of connecting rod is clamped.
The know-why of this fixture is, bracket can be promoted during bolt rotary move, one end that rocking arm is withstood in top on bracket makes rocking arm rotate; the other end of rocking arm moves to carrier direction; select the brachium of the suitable arm of force in rocking arm two ends; can make the first chuck on bracket and the second chuck synchronizing moving on rocking arm; during relative line of crossing on the end face of small end of connecting rod is looked for; the V-shaped groove that the first chuck and the second chuck are arranged can be located in Y direction small end of connecting rod, and the locking phase of the first chuck and the second chuck can be located in X-direction small end of connecting rod to movement.Compared with prior art this fixture can realize, to the centralized positioning of connecting rod small end hole, greatly improving drilling efficiency while clamping small end of connecting rod, and this fixture both can use and also can use on upright drill on radial drilling machine simultaneously.
