Description

Connecting rod cover semi-finished position inspection tool

technical field

The invention relates to the technical field of detection of engine connecting rod parts, in particular to a position inspection tool for a semi-finished product of a connecting rod cover. the

Background technique

The connecting rod of the engine is composed of the connecting rod body and the connecting rod cover. When the connecting rod cover and the connecting rod body are separately forged, the semi-finished product after the forging of the connecting rod cover is in the form of multiple connecting rod cover monomers side by side. The position of the screw hole on the joint surface of the semi-finished product is generally detected by a three-coordinate detection machine, which has high precision, but its detection is complicated, time-consuming, and low in efficiency, and is not suitable for mass production and processing of connecting rod cover semi-finished products. Rapid detection, and high requirements for the use of testing personnel, testing personnel need to undergo systematic training on the theoretical knowledge of three-coordinate testing, resulting in high testing costs. the

Contents of the invention

In view of the above problems, the present invention provides a position inspection tool for the semi-finished product of the connecting rod cover, which is simple and quick to detect, improves the detection efficiency, and is suitable for the rapid detection of the semi-finished product of the connecting rod cover. , further reducing the detection cost. the

Its technical solution is as follows: the semi-finished product position of the connecting rod cover includes a base plate, and the four corners of the bottom surface of the base plate are installed with feet through bolts. and a mechanical watch, one side of the reference seat is fixed to the bottom plate by bolts, and the other side is inserted and positioned on the bottom plate by two taper pins evenly distributed in the longitudinal direction, and the quick clip seat has two and Located on the left side of the reference seat, at both ends of its longitudinal direction, the quick clamp is fixed to the quick clamp seat through its flange surface, the screw hole on the bottom surface of the semi-finished connecting rod cover to be tested is positioned through the tapered end of the taper pin, The longitudinal ends of the upper surface are compressed and fixed by quick clips. the

It is further characterized by:

It includes a limit pin, the base plate has a perforation at the place where the taper pin is inserted, and the bottom plate is threaded with a groove nut at the bottom of the perforation, and the bottom of the taper pin has a groove, which is located at the bottom of the taper pin. A spring is installed between the bottom groove and the groove of the groove nut, and the side wall of the taper pin has a limiting groove, which is located on the side wall of the reference seat and corresponds to the limiting groove of the taper pin. The limit hole of the perforation, the limit pin is inserted into the limit hole, and one end thereof is located in the limit groove of the taper pin;

It also includes a measuring seat, a clamping block and a clamping ring. Corresponding to each taper pin, the base plate is equipped with a measuring seat. A guide hole is opened, and the clamping block is in interference fit with the guide hole of the measuring base. The mechanical watch is inserted into the clamping block and clamped by the clamping ring.

After adopting the present invention, its beneficial effects are: one side of the semi-finished connecting rod cover is positioned by the taper pin, and its upper end is clamped by a quick clamp, and whether the taper pin is inserted can quickly determine whether the semi-finished connecting rod cover has two adjacent connecting rod covers. Whether the positional relationship of the screw hole of the body meets the requirements, since the distance from the center of the taper pin to the end face of the measuring seat is known, the connection of the semi-finished product of the connecting rod cover can be quickly judged by using the mechanical gauge inserted in the measuring seat. Whether the distance from the center of the single screw hole of the rod cover to its end face meets the processing requirements, when testing the screw holes on the other side of the semi-finished connecting rod cover, it is only necessary to turn the direction of the semi-finished connecting rod cover to be tested; the detection is simple and fast, and improves It improves the detection efficiency and is suitable for the rapid detection of the semi-finished products of the connecting rod cover. At the same time, its operation is simple, which reduces the requirements for the detection personnel and further reduces the detection cost. the
