Problems solved by technology

[0002] In the process of machining the arc surface of the connecting rod, because the workpiece is very heavy (up to 67KG) and is shaped, the machined surface is not a full circle but an arc, and the roughness of the machined surface, the roundness of the machined surface and the The precision of the coaxiality between the processing surface and the inner hole is very high, and often only the machining center can be used to process the arc surface of the connecting rod, which takes a long time. The axial degree can not meet the requirements of finishing

Embodiment Construction

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] A method for clamping the arc surface of a finishing connecting rod of the present invention comprises the following steps:

[0029] (1) Use the headstock rotating mandrel conical surface locking nut to lock the headstock flange and the rotating mandrel of the grinding machine headstock;

[0030] (2) Install the flange of the fixed seat on the front side of the flange of the head frame, adjust the flange of the fixed seat and the flange of the head frame to be coaxial, and then lock and fix with screws; the bottom of the flange of the fixed seat Equipped with a counterweight, and the upper part of the flange of the fixed seat is provided with two clamping seats;

[0031] (3) Install the connecting flange of the clamping mandrel on the front side of the flange of the fixed seat, adjust the connecting flange of the clamping mandrel and the flange of...

Abstract

The invention provides a clamping method and device for finish machining of a connecting rod arc surface. A set of concentrically mounted flange plates are adopted to be coaxially connected with a rotary spindle of a grinding machine head frame, a workpiece inner hole is fixed through a fixing axis unit, a workpiece is clamped and fixed through a clamping seat, so that the large-scale workpieces can be stably and coaxially fixed on the rotary spindle of the grinding machine head frame. The clamping method and device have the advantages that installation is easy, use is convenient, the machining efficiency and the machining precision are high, generation of waste products can be reduced, the machining cost of arc surface machining can be greatly reduced, the product quality is fully guaranteed, and remarkable economic benefits are achieved.

Description

technical field [0001] The invention relates to a method and a device for clamping the arc surface of a finishing connecting rod, and belongs to the technical field of the finishing arc surface of a connecting rod of a numerical control grinding machine. Background technique [0002] In the process of machining the arc surface of the connecting rod, because the workpiece is heavy (up to 67KG) and has a special shape, the machining surface is not a full circle but an arc, and the roughness of the machining surface, the roundness of the machining surface and the The precision of the coaxiality between the machining surface and the inner hole is very high. Often, only the arc surface of the connecting rod can be processed by the machining center, which takes a long time. The axial degree also does not meet the requirements of finishing. [0003] Therefore, it is imperative to develop a clamping method that can finish the arc surface of the connecting rod on the grinding machin...
