Workpiece fixing device and method for cylinder cover machining

Abstract

The invention discloses a workpiece fixing device and method for cylinder cover machining. The workpiece fixing device is used for being installed on the top face of an operation platform. Lifting threaded rods are symmetrically arranged on the top surface of a bearing base through bearings, lifting sleeves are connected to the top ends of the lifting threaded rods in a sleeving mode, and the lifting sleeves are in threaded connection with the lifting threaded rods. Rotating guide rods are included, arranged in the lifting threaded rods in a penetrating mode and rotationally arranged on the top faces in the lifting sleeves through bearings. The bottom ends of the rotating guide rods are arranged in the bearing base in a penetrating manner. A driving shaft is rotationally arranged in the bearing base through a bearing, and a machining frame body is pre-arranged on the top surface of the bearing base. According to the workpiece fixing device for cylinder cover machining, overall overturning is carried out while height adjustment is carried out on the machining frame body through the bearing base and lifting mechanisms on the left side and the right side, the machining frame body clamps a cylinder cover, and the situation that the cylinder cover falls off and is damaged in the overturning process is prevented.

Description

technical field [0001] The invention relates to the technical field of workpiece processing, in particular to a workpiece fixing device and method for cylinder head processing. Background technique [0002] The cylinder head is a circular metal workpiece in the automobile engine. If the cylinder head is not fixed firmly during the manufacturing process, it will easily cause processing cracks. Due to the expansion of the cracks, the cylinder head will break far before reaching the strength limit of the material. . [0003] However, most of the cylinder heads cannot be fixed in all directions during processing, especially cylinder heads that cannot be well adapted to various diameters, sizes or structures. The applicability and versatility are poor, and it is easy to cause the fixing device to fail It is inconvenient to use, and because the overall weight of the cylinder head is relatively large, it is difficult for processing personnel to move the cylinder head only by manpo...

Problems solved by technology

[0005] The object of the present invention is to provide a workpiece fixing device and method for cylinder head processing, to solve the problem that most cylinder heads on the market cannot achieve all-round fixation of the cylinder head during processing, especially not very well. Adapt to cylinder heads with various diameters, sizes or structures, poor applicability and versatility, easy to cause inconvenience in the use of fixing devices, and because of the large overall weight of the cylinder head, it is difficult for processing personnel to carry out manual inspection of the cylinder head alone. The problem of moving
