Embodiment Construction

[0010] The specific embodiment of the present invention will now be described in conjunction with the accompanying drawings.

[0011] The positioning fixture for drilling the small head hole of the connecting rod includes a base body 1 fixed on the drilling machine workbench. The base body is composed of a horizontal plate and a vertical plate in a horizontal L shape. The horizontal plate of the base body is provided with a frame body 2. The shape of the frame body is "door" shape, the bottom ends of the two side walls of the frame body are attached to the horizontal plate of the base body, the end face of the small end of the connecting rod 14 rests on the top wall of the frame body, and the end face of the small end of the connecting rod is placed The support body top wall part is provided with process hole 8, and process hole is the diameter of the drill bit that its diameter of through hole is greater than the drill connecting rod small head hole.

Abstract

The invention discloses a positioning fixture for drilling a hole in a small end of a connecting rod. The positioning fixture comprises a matrix (1) which is fixed on a drilling machine worktable, wherein a frame body (2) is arranged on the matrix, a first chuck (3) and a second chuck (41) are arranged on the frame body, the first chuck is fixed on the top wall of the frame body, and the second chuck can move on the top wall of the frame body; a first ejector rod (7) is arranged on the side wall of the frame body, the lower arm of a rocker arm (4) is propped against the head of the first ejector rod, the head of a second ejector rod (71) which is arranged at the one end of the second chuck is propped against the upper arm of the rocker arm, and the rocker arm can rotate around a mandrel (9); when the frame body is pushed, the first chuck and the second chuck can synchronously move in opposite directions, and the excircle part of the small end of a connecting rod is clamped by V-shaped grooves in the first chuck and the second chuck. The positioning fixture can position the drilling hole in the position where the small end of the connecting rod is clamped, so that the efficiency of drilling the hole in the small end of the connecting rod is greatly improved.

Description

technical field [0001] The invention relates to a positioning fixture for drilling a small end hole of a connecting rod. The positioning fixture is used for positioning and clamping the small end of the connecting rod so that the drilled hole is at the center of the small end of the connecting rod. Background technique [0002] The small head of the connecting rod is integrally formed with the body of the connecting rod. The small head of the connecting rod is an irregular cylinder, and there is a certain error in the outer diameter of the small head. Before drilling the small head of the connecting rod, Usually, according to the outer diameter of the small end of the connecting rod, draw a cross line on the end surface of the small end of the connecting rod to mark the center of the small end, then fix the connecting rod on the workbench of the radial drilling machine, move the drill bit to Drill holes at intersections. This method of drilling is not efficient and needs to...
