Description

Fixture for machining big end of connecting rod with outer circle positioning

technical field

The utility model relates to a process equipment for mechanical processing, in particular to a process equipment for processing the big end of a connecting rod.

Background technique

Due to the irregular external shape of the big end of the connecting rod, it is difficult to process and locate during turning, and it is difficult to achieve machining accuracy. In addition, the current processing equipment is inconvenient to install, resulting in high processing hours and increased processing costs.

Utility model content

The purpose of this utility model is to provide a fixture for processing the large end of connecting rod with outer circle positioning. The cost of processing.

The fixture for processing the large end of the connecting rod with outer circle positioning of the utility model is composed of a base 1, a splint 2, a helical compression spring 3 and a bolt 4, and the base 1 has a base side hole 1-1 and a base center hole 1-2; the splint 2. Set above the center hole 1-2 of the base 1. There is a circular groove 2-1 on the splint 2. The center of the circular groove 2-1 is aligned with the center of the center hole 1-2 of the base. The circular groove The groove 2-1 runs through to the edge of the splint 2; there is a bolt 4 on the left and right parts of the splint 2, and the bolt 4 connects the splint 2 to the base 1, and the screw rod of the bolt 4 is equipped with a helical compression spring 3, which is a helical compression spring 3 The two ends rest on the base 1 and the splint 2.

The clamp for processing the large end of the connecting rod with outer circle positioning of the utility model has the advantages of easy installation, high processing and positioning accuracy, fast processing and low processing cost.

Fig. 1 is a structural representation of the utility model;

Fig. 2 is a cross-sectional view along line A-A of Fig. 1 .

Detailed ways

Below in conjunction with accompanying drawing and with best embodiment the utility model is described in detail.

Referring to Figure 1-2, the fixture for processing the large end of the connecting rod with outer circle positioning is composed of a base 1, a splint 2, a helical compression spring 3 and a bolt 4, and the base 1 has a base side hole 1-1 and a base center hole 1-2 Clamping plate 2 is arranged on the base center hole 1-2 top of base 1, and there is a circular groove 2-1 on splint 2, and the center of circle of circular groove 2-1 is aligned with the center of circle of base center hole 1-2, and the circle The groove 2-1 runs through to the edge of the splint 2; there is a bolt 4 at the left and right parts of the splint 2, and the bolt 4 connects the splint 2 with the base 1, and a helical compression spring 3 is set on the screw rod of the bolt 4. Two ends of the compression spring 3 bear on the base 1 and the splint 2 .

When in use, the small end of the connecting rod is installed in the side hole of the base through bolts, and the protruding outer edge of the large end hole of the connecting rod is inserted into the circular groove of the splint, and fixed by the bolt and the splint. The splint can be loosened and removed by loosening the bolt, and the connecting rod can be installed or removed.

The above embodiment is one of the more preferred specific implementations of the utility model, and ordinary changes and substitutions performed by those skilled in the art within the scope of the technical solution shall be included in the protection scope of the utility model.
