Abstract
The invention provides a positioning clamp which is used for positioning and clamping a connecting rod in a process of multistep integrated machining by utilizing a numerical-control machining center and is significant for concentrating the procedures such as the milling of an end surface of the connecting rod in small-lot production and cutting of a small-end hole. According to the positioning clamp provided by the invention, a positioning way, a clamping method and an overturning function convenient to operate of the connecting rod are effectively designed. The connecting rod can be overturned in a machining process, the repeated positioning and clamping times of the connecting rod when the front end surface and the back end surface of the connecting rod are milled can be reduced, so that the possibility of the positioning error in the machining process can be reduced. When the positioning clamp is used for positioning and clamping, a machined surface of the connecting rod is adequately used as a positioning benchmark, and through the assistance of an auxiliary clamping device, a bending moment produced by the cutting force in the radial direction and the axial direction in the machining process can be counteracted, and the machined member cannot be subject to the deformation caused by the large bending distance in the machining process. The positioning clamp is simple to operate and precise to position; and meanwhile, a great amount of clamping time and labor cost can be saved.
