Abstract

The invention relates to a processing clamp apparatus for a rocker of an automobile engine. A rectangular slot-shaped clamp apparatus body is arranged between a left supporting seat and a right supporting seat; six to ten chip removal holes coordinated with shaft holes of the rocker is uniformly distributed on a slot bottom of the clamp apparatus body along the left and right directions while a supporting ring is arranged on an upper hole port of the chip removal hole on the external side of the slot bottom of the clamp apparatus body; a front saddle is arranged in the front of the upper hole port and a mandril slideway is arranged in the rear part of the upper hole port along the left and the right directions; a mandril is positioned inside the mandril slideway and a mandril cam is pressed against and connected with the rear end of the mandril; a spring is positioned between the mandril and the mandril slideway; a levers in front and rear direction with fulcrums above the mandril slideway is arranged in the rear part of the upper hole port; a pressure fork is articulated with the front end of the lever while a link rod is arranged on the rear end of the lever; a link rod cam is pressed against and connected with the lower end of the link rod and the front end of a cam shaft is provided with a hand wheel. The invention has multi-station and can fulfill the assembly and disassembly of workpieces by rotating two cams of the mandril cam and the lever cam, which provides great convenience to the assembly and the disassembly of the workpieces. In addition, when a blank is placed on the clamp apparatus, the blank is strictly constrained and stably clamped on the clamp apparatus, without deformation due to reasonable force bearing.

Description

technical field [0001] The invention relates to a jig used for cutting mechanical parts with a cutting machine tool, in particular to a jig for machining a rocker arm of an automobile engine. Background technique [0002] The rocker arm of the automobile engine is processed by cutting the casting blank of the rocker arm of the automobile engine with a cutting machine tool. The rocker arm of the automobile engine is in the shape of a curved arm. When the casting blank is processed into a product, it is necessary to use a cutting machine tool to cut multiple processing surfaces in multiple directions of the casting blank to process the rocker shaft hole and the rocker shaft hole. Planes, bearing frames, bearing holes, hydraulic tappet holes, etc., require high processing precision after processing. In order to facilitate cutting and ensure machining accuracy, the machining center can be used to cut the blank when machining the blank. When using the machining center to cut and...
