Abstract
The utility model discloses a boring fixture for engine cylinder cover camshaft bearing caps. The boring fixture for engine cylinder cover camshaft bearing caps is mounted on a machine tool which is provided with a compressing mechanism. The fixture comprises a positioning support for holding a bearing cap and a positioning mechanism which is disposed on the positioning support and which is used for positioning the bearing cap. The compressing mechanism is used for compressing the bearing cap on the positioning support. The positioning support is further provided with a semicircular hole which matches with a camshaft hole of the bearing cap in precision and position. Compared with the prior art, the boring fixture for engine cylinder cover camshaft bearing caps is simple in structure, is available for compressing the bearing cap by placing the bearing cap on the positioning support in each clamping, and is convenient to use and efficient in clamping.
Description
Technical field
The utility model relates to the engine cubing, and specifically, the utility model relates to a kind of engine cylinder cover camshaft-bearing cap boring jig.
Background technology
At present, camshaft of car engine fixing on its cylinder cap generally be framework by an integral body be installed in engine cylinder cover above, and be to finish by some bolting.Be cast with half camshaft bearing hole with the cylinder cap correspondence on the whole framework, after this dead eye bearing cap corresponding with it is with bolting, need carry out accurate processing to it and satisfy the performance requirement of engine operation to guarantee whole camshaft hole, generally be that bearing cap will carry out a bore hole processing before fine finishining, just can carry out finishing of this finishing step afterwards.But often adopt built-up jig general on the lathe to realize that frock clamps in the most bore hole process, this just needs the operator that very masterful technique is arranged, and the operator is consuming time a lot of when selecting for use and general built-up jig is installed, and this has caused unnecessary influence again to cylinder cap bearing cap working (machining) efficiency.Secondly, bearing cap of the bore hole of ordinary circumstance lower ball cover each clamping of processing, it also is lower coming angle to say from processing benefit.So select for use a kind of special use, efficiently, accurately a kind of engine cylinder cover camshaft-bearing cap bore hole clamp for machining of clamping just seems particularly urgent.
The utility model content
Technical problem to be solved in the utility model is a kind of engine cylinder cover camshaft-bearing cap boring jig, to improve bearing cap adds man-hour at bore hole clamping efficient.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of engine cylinder cover camshaft-bearing cap boring jig, be installed on the lathe, has hold-down mechanism on the lathe, described anchor clamps comprise for the positioning supports seat of placing described bearing cap and are located at the detent mechanism that bearing cap is positioned on this positioning supports seat, described hold-down mechanism is used for bearing cap is pressed on the positioning supports seat, also is provided with on the positioning supports seat and the camshaft hole precision of bearing cap, the semicircle orifice that the position matches.
Described detent mechanism comprises cylinder alignment pin and the rhombus alignment pin of the semicircle orifice both sides that are distributed in described positioning supports seat, cylinder alignment pin and rhombus alignment pin and with described bearing cap on the aligned in position of bolt hole.
Described cylinder alignment pin and described rhombus alignment pin are respectively equipped with two.
The utility model adopts technique scheme, and compared with prior art, this clamp structure is simple, and is as long as bearing cap is placed on the position of setting on the positioning supports seat and compresses, easy to use during each clamping bearing cap, clamping efficient height.
Description of drawings
Fig. 1 is the vertical view of the utility model anchor clamps;
Fig. 2 is the A-A cutaway view among Fig. 1;
Mark among the above-mentioned figure is: 1, cylinder alignment pin; 2, positioning supports seat; 3, rhombus alignment pin; 4, bearing cap; 5, bolt.
The specific embodiment
As depicted in figs. 1 and 2, a kind of engine cylinder cover camshaft-bearing cap of the utility model boring jig, it comprises for the positioning supports seat 2 of placing bearing cap 4 and is located at the detent mechanism that bearing cap 4 is positioned on this positioning supports seat 2, positioning supports seat 2 is installed on the lathe by two bolts 5 at the certain location place, on the lathe and have a hold-down mechanism, hold-down mechanism is used for bearing cap 4 is pressed on positioning supports seat 2, also is provided with on positioning supports seat 2 and the camshaft hole precision of bearing cap 4, the semicircle orifice that the position matches.Detent mechanism comprises cylinder alignment pin 1 and the rhombus alignment pin 3 of the semicircle orifice both sides that are distributed in positioning supports seat 2, cylinder alignment pin 1 and rhombus alignment pin 3 and with bearing cap 4 on the aligned in position of bolt hole.Cylinder alignment pin 1 and rhombus alignment pin 3 are fixed in the installing hole that arranges on the positioning supports seat 2.When clamping bearing cap 4, the bearing cap 4 for the treatment of bore hole is installed on the positioning supports seat 2 by cylinder alignment pin 1 and rhombus alignment pin 3, at last with the hold-down mechanism on the lathe push down bearing cap 4 above.Whole bearing cap 4 just is completely fixed and can have been processed.
As shown in Figure 1, cylinder alignment pin 1 and rhombus alignment pin 3 in the semicircle orifice both sides of positioning supports seat 2 are respectively equipped with two, so just can process simultaneously by two bearing caps 4 of a clamping, further improve the efficient of clamping in bearing cap 4 processing, also reduced the time of bearing cap 4 bore holes processing widely.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
