Abstract
The invention relates to a split-type valve spring seat, which comprises a stepped disc and a taper hole sleeve, wherein a circular hole with a disc step is arranged in the middle of the stepped disc; the taper hole sleeve is cylindrical, and a sleeve step is arranged at the upper end of the taper hole sleeve; the outer diameter of the cylinder of the taper hole sleeve is same as the inner diameter of the circular hole of the stepped disc; and the inner diameter of the disc step is same as the outer diameter of the sleeve step. The split-type valve spring seat has the beneficial effects that: the production efficiency is high, and the working efficiency can be improved by 3-5 times compared with a machining process mostly based on round steel turning in the prior art; the material utilization ratio is high; and the surface treatment of each component is easy, therefore the precision of the surface size is conveniently improved.
Description
Technical field
The present invention relates to a kind of engine valve assembly, relate in particular to a kind of split type cotter seat.
Background technique
Cotter seat is the effect that is used for restriction cotter seat position in the engine air door assembly; Have the seat of honour and following branch; Form according to different engine valves, seat has different shapes and specification up and down, but moulding process all is the same with treatment process; It is round steel → car ladder platform → bore basic hole → cut-out → car taper hole → surface turning chamfering → heat treatment → surface treatment; The product that forms is an integral structure all, when adopting this explained hereafter cotter seat, has following problem; The one, stock utilization is low, and particularly during car ladder platform, a lot of waste material under the car causes the significant wastage of material, and according to calculating, stock utilization is less than 50%; The 2nd, manufacturing efficiency is low, certainly will improve cost of production.The cotter seat that does not also have appearance to be assembled in the existing technology by split type parts.
Summary of the invention
The purpose of this invention is to provide a kind of split type cotter seat, solved low, the low problem of stock utilization of manufacturing efficiency that existing cotter seat exists.
The objective of the invention is to realize through following technological scheme:
A kind of split type cotter seat; Comprise ladder dish and taper hole cover; Be provided with the circular hole of a tep reel step in the middle of the said ladder dish, the taper hole cover is cylindrical shape, and its upper end is provided with the cover step; Wherein the external diameter of taper hole cover cylinder is identical with the internal diameter of ladder dish circular hole, and the internal diameter of dish step is identical with the external diameter of cover step.
Beneficial effect of the present invention is:
1, manufacturing efficiency is high, and ladder dish and tapered sleeve hole can be distinguished punching press and accomplish, and assemble the all-in-one-piece cotter seat then, than being master's processing technology with round steel turning in the existing technology, can improve work efficiency 3-5 times;
2, stock utilization is high, because ladder dish and taper hole cover directly are stamped to form through after the accurate blanking, does not produce waste material in the course of working, therefore, has improved the utilization ratio of material significantly with respect to existing technology;
3, the surface treatment of each parts is easy, is convenient to improve the precision of surface size.
Description of drawings
According to accompanying drawing the present invention is done further explain below.
Fig. 1 is the sectional view of ladder dish;
Fig. 2 is the sectional view of taper hole cover;
Fig. 3 is an erection drawing of the present invention.
Among the figure:
1, ladder dish; 2, taper hole cover; 3, dish step; 4, cover step; 5, circular hole.
Embodiment
Shown in Fig. 1-3, the described a kind of split type cotter seat of the embodiment of the invention comprises ladder dish 1 and taper hole cover 2; Be provided with the circular hole 5 of a tep reel step 3 in the middle of the said ladder dish 1, taper hole cover 2 is a cylindrical shape, and its upper end is provided with cover step 4; Wherein to overlap the external diameter of 2 cylinders identical with the internal diameter of ladder dish 1 circular hole 2 for taper hole, and the internal diameter of dish step 3 is identical with the external diameter of cover step 4, and ladder dish 1 and taper hole overlap 2 and be stamped to form by steel; Through Overheating Treatment, surface treatment; Be assembled into product, be fixed together, can both be fixed through the form of gang welding for making ladder dish 1 and taper hole cover 2.
