Abstract

The invention discloses machining equipment for producing a truck engine piston. The machining equipment comprises a workbench, a hydraulic cylinder arranged on the table top of the workbench, a drilling device, a piston blank feeding device and an end face grinding device, the drilling device is arranged on the right side of the hydraulic cylinder, the piston blank feeding device is arranged on the front side of the hydraulic cylinder, and the end face grinding device is arranged on the right side of the piston blank feeding device and arranged between the hydraulic cylinder and the drilling device; and a movable plate is fixedly arranged at an acting end of a piston rod of the hydraulic cylinder, a sliding table is fixedly arranged on the top surface of the movable plate, a power unit and a tool clamp are arranged on the top surface of the sliding table, the tool clamp comprises an upper pressing block, a lower pressing block and a rack, and the rack is fixedly arranged on the top surface of the sliding table. The machining equipment has the beneficial effects that the piston machining efficiency is improved, the piston blank tool efficiency is improved, the labor intensity of workers is relieved, and the oil passing hole machining precision is improved.

Description

technical field [0001] The invention relates to the technical field of processing truck engine pistons, in particular to processing equipment and a processing method for producing truck engine pistons. Background technique [0002] The engine is the power part of the truck. The engine is mainly composed of cylinders, pistons, connecting rods, crankshafts, valve trains, propeller reducers, casings, etc. The piston is an important part of the engine. It is a reciprocating motion in the cylinder block of the truck engine. parts. The structure of the piston is as Figure 1~2 As shown, two oil holes 35 are opened on its cylindrical surface, and the two oil holes 35 are arranged symmetrically. The process steps of processing the piston are first to use the press-fitting device to install the piston blank on the table of the drilling rig, drill the first oil hole 35 on the cylindrical surface of the piston blank through the drilling rig, and then turn the piston blank 180°, turn o...

Problems solved by technology

Yet, although the method for this processing piston can process piston, following defect still exists: 1, when drilling the second oil passage hole, need carry out tooling to piston blank again and fix, and this has undoubtedly increased accumulation positioning error, causes The two processed oil holes are asymmetrical, which reduces the machining accuracy of the oil holes

2. Transferring from the drilling station to the grinding station increases the transfer cycle and reduces the processing efficiency of the piston. In addition, special fixtures are required to fix the piston blank before grinding, which further increases the processing time of the piston and further reduces the processing efficiency of the piston

3. The pressing device is a pressing plate. When the tooling is used to fix the piston blank, the worker needs to press multiple pressing plates on the cylindrical surface of the piston blank to fix the piston blank. This not only increases the labor intensity of the worker, but also reduces the tooling. Efficiency of piston blanks

4. The piston blank is heavy and bulky, and it is difficult to manually transport the piston blank to the table of the drilling rig, which is time-consuming and laborious
