Abstract
The invention discloses a hold-down device for air valve spring. The hold-down device comprises a stud; a support, an anti-thrust column, a washer and a nut; a tumbler is arranged on a side surface of the anti-thrust column; an inverted U-shaped clamping groove is formed below the tumbler; a lower end of the tumbler is connected with a chuck; a through hole is formed in the center of the chuck. On the basis of an idea of rotation, during assembling, an angle of the anti-thrust column is rotated to change a position of mounting and demounting the air valve spring; due to a planar contact manner between the anti-thrust column and the air valve spring, the spring can be compressed steadily and controllable amount of compression of the spring can be guaranteed; the probability of elastic deformations caused by excessive compression of the spring can be reduced and a purpose of demounting a plurality of air values by mounting the tool once can be achieved, and furthermore, the mounting times of the tool are reduced.
Description
Technical field
The present invention relates to a kind of hold down gag on spring for valve, belong to field of mechanical technique.
Background technology
Spring for valve is arranged in air valve, plays vital effect to the service behaviour of air valve.In real work, often can run into the situation of the more gentle valve spring of scavenging air valve, therefore readyly compression is carried out to it remove and install.Existing spring for valve compaction tool is not easy to dismantle, and have the danger that press mounting tool landing occurs, cause valve conical ring intwo part to fly out and hurt sb.'s feelings, meanwhile, because its same cylinder head is repeatedly installed, efficiency is low; Complex structure carries and uses also inconvenient.
Summary of the invention
Given this, the invention provides one and achieve easy to carry, simple to operate, be convenient to the hold down gag on spring for valve assembled.
Its technical scheme is as follows:
A kind of hold down gag on spring for valve, comprise stud, this stud is provided with support, stop post, packing ring and nut from the bottom up successively, the side of described stop post is provided with pivoted arm, the below of this pivoted arm is provided with inverted U-shaped draw-in groove, the lower end of described pivoted arm is connected with chuck, and this chuck hub is provided with perforation.Design like this, adopt rotation theory, change the position of dismounting spring for valve with the angle rotating stop post when assembling, by the flat surface contact manner of stop post and spring for valve, can make spring-compressed steadily and ensure that amount of spring compression is controlled, reducing spring-compressed and too much cause elastically-deformable probability.
As preferably, described support is strip, and along the symmetrical distribution of stud, the below at these support two ends is respectively provided with a fixed block.Design like this, better can fix inspiration spring compression instrument.
As preferably, the lower end of described stud is provided with rounded corner.Adopt this result, convenient installation.
As preferably, the upper surface metal binding agent of described packing ring and stop post carries out bonding.Design like this, makes overall structure more firm.
Beneficial effect:
The hold down gag on spring for valve of above technical scheme, adopt rotation theory, change the position of dismounting spring for valve with the angle rotating stop post when assembling, by the flat surface contact manner of stop post and spring for valve, can make spring-compressed steadily and ensure that amount of spring compression is controlled, reduce spring-compressed and too much cause elastically-deformable probability, play and fill the object that instrument can tear multiple air valve open, decrease the installation number of times of instrument, improve operating efficiency, avoid the danger that press mounting tool landing occurs when dismantling simultaneously, easy to carry, simple to operate, be convenient to assembling.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
The hold down gag on spring for valve as depicted in figs. 1 and 2, comprise stud 5, the lower end of this stud 5 is provided with rounded corner, convenient installation, described stud 5 is provided with support 1, stop post 2, packing ring 3 and nut 4 from the bottom up successively, and described support 1 is strip, and along the symmetrical distribution of stud 5, the below at these support 1 two ends is respectively provided with a fixed block 11, and this fixed block 11 is provided with nut.
The side of described stop post 2 is provided with pivoted arm 21, this pivoted arm 21 is in half " C " font, and stretch out the below of support 1, inverted U-shaped draw-in groove 210 is provided with below pivoted arm 21, the lower end of this U-shaped draw-in groove 210 is connected with chuck 22, this chuck 22 center is provided with perforation 220, and perforation 220 communicates with U-shaped draw-in groove 210.The upper surface metal binding agent of described packing ring 3 and stop post 2 carries out bonding.
During use, support 1 is fixed on cylinder cover, then chuck 22 is fixed on spring for valve fixture block, spring for valve fixture block stretches into U-shaped draw-in groove 210 by perforation 220, compressed by fastening nut 4 pairs of spring for valves, chuck 22 and the flat surface contact manner of spring for valve, can make spring-compressed steadily and ensure that amount of spring compression is controlled.Meanwhile, the angle that can rotate stop post 2, to change the position of dismounting spring for valve, plays and fills the object that instrument can tear multiple air valve open, decrease the installation number of times of instrument.
