Abstract
The utility model relates to a hydraulic fixture used for finishing a support-type seal tape of a cylinder cover of a diesel engine. The hydraulic fixture comprises an oil cylinder assembly, a base, a compression disc and a compression bar, wherein the base of a fixture body is positioned and arranged on a machine tool through a positioning key; the oil cylinder assembly is arranged in the base of the fixture; the compression disc of the fixture is arranged at the top end of an oil cylinder push rod; and a return diagonal iron is arranged at the lower end of the compression bar. After the cylinder cover of the diesel engine is placed in the fixture, a hydraulic cylinder pushes and compresses the compression disc, and then a locking diagonal iron pushes the compression bar to compress the cylinder cover of the diesel engine to be automatically locked. The fixture is loosened after machining a valve guide pipe hole of the cylinder cover and a sealing conical surface composite hole. In the utility model, the mechanical diagonal iron self-locking and the hydraulic control loop self-locking are adopted, and the cutting force is calculated according to the cutting parameters of different products to adjust the clamping force, so that the hydraulic fixture has stronger generality and compact structure, is convenient to operate and greatly improves the production efficiency.
Description
Technical field
The utility model relates to a kind of diesel engine cylinder cover pop-up formula band fine finishining hydraulically operated fixture.
Background technology
In the manufacturing procedure of diesel engine part, particularly the processing of valve guide hole and sealing cone composite holes is a very crucial procedure in the cylinder head, the above diesel engine cylinder cover of four valve Europe III all require usually the relative guide hole axis of seat ring sealing cone beat≤0.05, and a cylinder center and the six cylinder centre distances of working as the high-end six cylinder four-valve cylinder heads of forward part surpass more than the 600mm, this just causes the anchor clamps of original old-fashioned manual clamping, valve deflection uniformity can't guarantee that this also directly has influence on detonation pressure power and air flue consistency of performance.Therefore needing a kind of novel anchor clamps badly remedies this defective.
The utility model content
The utility model provides a kind of diesel engine cylinder cover pop-up formula band fine finishining hydraulically operated fixture, this kind anchor clamps can be realized mechanical wedge self-locking, hydraulic control circuit self-locking, and can regulate clamping force according to the cutting force that the different product cutting parameter calculates, highly versatile not only, and clamp automatically, compact conformation, easy to operate, easy to assembly, low production cost.
For achieving the above object, by the following technical solutions:
A kind of diesel engine cylinder cover pop-up formula band fine finishining hydraulically operated fixture, its composition comprises the oil hydraulic cylinder assembly, base, compress disk, positioning sleeve, turning set, bearing pin, move back wedge, with self-locking wedge etc., described clamp body base passes through the positioning key location and installation on lathe, the oil hydraulic cylinder assembly is in the base of anchor clamps, for anchor clamps provide the driving clamping force, clamp body is installed on the base, the left and right sides is that a side plate is respectively arranged, be fixed with gib block by dog screw on the side plate, there is upper cover plate the upper end, the disk that compresses of described anchor clamps is tightened by round nut and is installed in the compressor arm top, bearing pin is housed on the compressor arm, be set with turning set outward, the self-locking wedge is arranged under the turning set, its lower end is equipped with moves back wedge, after diesel engine cylinder cover is put into anchor clamps, gib block on the side cover plate and the fairlead on the upper cover plate and spacer pin are auxiliary accurately locatees cylinder head, oil hydraulic cylinder promotes to compress disk and compresses diesel engine cylinder cover, two groups of oil hydraulic cylinders promote compressor arm after compacted position by the rolling cover that the self-locking wedge promotes on the compressor arm in addition, auto lock, finish processing to diesel engine cylinder cover valve guide hole and sealing cone composite holes, machine the back under the driving of oil hydraulic cylinder, anchor clamps unclamp tight diesel oil cylinder cap, finish operation.
Because the utility model has adopted mechanical wedge self-locking, hydraulic control circuit self-locking, and the cutting force adjusting clamping force that can calculate according to the cutting parameter of different product, make that versatility of the present utility model is stronger, and compact conformation, simple operation has improved production efficiency greatly.
