Abstract
The invention provides an embedded type piston ring wet type edge grinding machine guide key which comprises base bodies (1, 6 and 8), key bodies (3, 7 and 9) and connection bolt holes (2,4 and 5). The guide key is characterized in that the base bodies and the key bodies of the guide key are manufactured separately, the key bodies of the guide key are made of hard alloy, the key bodies of the guide key and grooves of the base bodies are in interference fit, interference fit portions of the key bodies and the base bodies are manufactured into rectangles, after assembly of the key bodies and the base bodies is finished, portions exposed out of the base bodies are manufactured into a trapezoid shape, the lower end of each key body is manufactured into an inclined face, the two connection bolt holes are machined in the base bodies so that the base bodies can be firmer when being fixed, the defect that the base bodies rotate when one connection bolt works is overcome, and internal threads are machined in the two connection bolt holes. Replacement frequency of the embedded type piston ring wet type edge grinding machine guide key is reduced in actual use, the trouble of frequently replacing tools is eliminated for operators, and the guide key also makes due contribution to cost reduction and efficiency improvement of enterprises.
Description
Technical field:
The invention belongs to piston ring and produce equipment frock, be specifically related to a kind of embedded piston ring wet type and repair a mouthful machine feather key.
Technical background:
It is known that piston ring is a kind of important spare part in automobile engine, and piston ring be high temperature, high pressure, stress alternation,
Working in the poorest this adverse circumstances of lubricating condition, in addition to main frame is supporting, the replacement frequency of In-Use Motor Vehicles piston ring is the most at a relatively high on the market,
Causing this parts social required quantity big, make a general survey of manufacturing enterprise, its objective is cost minimization, and interests efficiency maximizes.With regard to piston ring repair opening
For production process, traditional to repair mouthful machine feather key short for not only service life, also brings the worry frequently changing frock to operative employee, simultaneously
Also have impact on production efficiency and economic benefit.In order to achieve the above object, therefore a mouthful machine feather key will be repaiied and be fabricated to split, be i.e. matrix and key body
It is fabricated separately, and feather key uses hard alloy, improves its wearability, key system is made the rectangular and trapezoidal shape combined simultaneously, prolongs
Grow operative employee and changed the time interval of frock, substantially increased production efficiency, also reduced frock making cost, reached enterprise and dropped this increasing
The purpose of effect.
Summary of the invention:
Technical solution of the present invention, feather key matrix and key body are fabricated separately, and feather key key body material uses hard alloy, feather key key body
And using interference fit to be attached between groove of substrate, key body and matrix Fit are fabricated to rectangle, and after assembling, naked leakage is at matrix
Outside part be fabricated to trapezoidal shape, and key body lower end is fabricated to an inclined-plane, matrix is processed two link bolts hole so that when fixing more
Add firmly, the disadvantage rotated when overcoming a link bolt hole job, in two link bolts hole, be all machined with interior tooth；
Feather key key body uses different materials with matrix, and feather key key body uses hard alloy, improves the wearability of feather key key body, extends
In the service life of feather key, even if feather key key body excessive wear, the most only need to change its key body, and without changing matrix, matrix can repeat
Use；
Feather key key body rectangle part uses interference fit to be connected with key body groove, has stopped the waste of enterprise's frock material, for enterprise
Industry cost efficiency is made that contribution.
Accompanying drawing illustrates:
Fig. 1 is that one embedded piston ring wet type of the present invention repaiies a mouthful machine feather key structure front schematic view；
Fig. 2 is that one embedded piston ring wet type of the present invention repaiies a mouthful machine feather key texture edge schematic diagram；
Fig. 3 is that one embedded piston ring wet type of the present invention repaiies a mouthful machine feather key structure schematic top plan view.
Detailed description of the invention:
Below in conjunction with the accompanying drawings 1, one embedded piston ring wet type of the present invention is repaiied a mouthful machine feather key texture edge schematic diagram by Fig. 2, Fig. 3
It is described in further detail；
From Fig. 1, Fig. 2, Fig. 3, this enforcement is that a kind of embedded piston ring wet type repaiies a mouthful machine feather key, by matrix (1,6,8),
Key body (3,7,9), link bolt hole (2,4,5) is constituted, it is characterised in that: feather key matrix and key body are fabricated separately, feather key
Key body material uses hard alloy, uses interference fit to be attached between feather key key body and groove of substrate, key body and matrix Fit
After being fabricated to rectangle, key body and matrix assembling, naked leakage part outside matrix is fabricated to trapezoidal shape, and key body lower end is fabricated to one
Inclined-plane, matrix is processed two link bolts hole so that more firm when fixing, overcomes the disadvantage rotated when a link bolt hole works,
Interior tooth all it is machined with in two link bolts hole；
In the technical program, this embedded piston ring wet type is repaiied a mouthful machine feather key and is changed the frequency in actual use and reduced, for behaviour
Workmanship eliminates the worry frequently changing frock, is made that its due contribution for enterprise's cost efficiency especially.
Claims (1)
