Abstract
The invention discloses a fixture for drilling a connecting rod small end hole. The fixture comprises a basal plate (1); an II-shaped bracket (2) is arranged on a horizontal plate of the basal plate; a support plate of the support frame supports a small-end end surface of a connecting rod (14); a first chuck (3) is fixed on the support plate positioned on the left side of the connecting rod small end; a screw rod (5) is screwed on a vertical plate of the basal plate; one end of the screw rod is butted against a frame plate on the left side of the support frame; the horizontal plate of the basal plate is fixedly connected with a bracket (10); a rocker arm (4) is connected to the bracket through a mandrel (9); an ejector head (7) arranged on the support frame is butted against one end of the rocker arm; a second chuck (41) is arranged at the other end of the rocker arm; V-shaped grooves are formed in the first chuck and the second chuck; groove surfaces of the V-shaped grooves can be contacted with the outer circular part of the connecting rod small end; and the screw rod rotates to synchronously move the first chuck and the second chuck oppositely so as to clamp the connecting rod small end. The fixture can realize center positioning of the connecting rod small end hole when clamping the connecting rod small end, so that the drilling efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of boring grab, be used for the hole boring in small end of connecting rod.
Background technology
Generally before the hole bored 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 cross hairs microcephaly to connecting rod looks for, then connecting rod is clamped, drill bit on radial drilling machine is directed at the midpoint boring of cross hairs, such boring method is more complicated, and work efficiency is not high.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of fixture boring connecting rod small end hole, and this fixture has the function of the centralized positioning to connecting rod small end hole, clamping, can improve the work efficiency boring connecting rod small end hole.
The fixture of this brill connecting rod small end hole includes the substrate 1 being fixed on Drilling machines bench, substrate is horizontal L-shaped, it is made up of horizontal plate and vertical plate, the horizontal plate of substrate is provided with the bracket 2 of �� font, bracket is made up of one block of supporting plate and two pieces of frame plates, the horizontal plate of the bottom of frame plate and substrate is 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 further fixedly arranged on the guide post 6 of cylinder, 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 being 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 rod can make the first chuck and the second chuck synchronizing moving in opposite directions be clamped by small end of connecting rod.
The know-why of this fixture is, screw rod can promote bracket to move when rotating, one end of rocking arm is withstood in top on bracket makes rocking arm rotate; the other end of rocking arm moves to carrier direction; the brachium of the arm of force that selection rocking arm two ends are suitable; can make the first chuck on bracket and the second chuck synchronizing moving on rocking arm; during line of relatively crossing on the end face of small end of connecting rod is looked for; small end of connecting rod can be positioned by the first chuck and the V-shaped groove arranged on the second chuck in Y direction, and the synchronization of the first chuck and the second chuck moves towards can to small end of connecting rod in X-direction location. Compared with prior art this fixture can realize the centralized positioning to connecting rod small end hole while clamp linkage microcephaly, is greatly improved drilling efficiency, and this fixture both can use on radial drilling machine and also can use on upright drill simultaneously.
