Abstract
The utility model discloses a pneumatic valve spring application instrument, including the double -screw bolt, this double -screw bolt is followed and is up installed support, thrust post, packing ring and nut down in proper order, the side of thrust post is provided with the rocking arm, and the below of this rocking arm is provided with the draw -in groove of falling the U -shaped, the lower extreme of rocking arm is connected with the chuck, and this chuck center is provided with the perforation. Rotatory theory is adopted in so design, changes the position of dismouting pneumatic valve spring when the assembly with the angle of rotating the thrust post, and through the plane contact of thrust post with the pneumatic valve spring, enabling spring compression, steady and guarantee spring compression volume is controllable, and reduction spring compression too much causes elastic deformation's probability, plays the purpose that a plurality of pneumatic valves can be torn open to the instrument adorned, has reduced the installation number of times of instrument.
Description
Technical field
This utility model relates to a kind of spring for valve compaction tool, belongs to field of mechanical technique.
Background technology
Spring for valve is arranged in air valve, and the service behaviour of air valve is played vital effect. Real work is frequently encountered the situation of the more gentle valve spring of scavenging air valve, therefore ready it is carried out compression remove and install. Existing spring for valve compaction tool is not easy to dismantle, and has the danger that press mounting tool landing occurs, causes that valve conical ring intwo part flies out and hurt sb.'s feelings, simultaneously as its same cylinder head is repeatedly installed, efficiency is low; Structure complexity is carried and uses also inconvenient.
Utility model content
In consideration of it, this utility model provides one to achieve easy to carry, simple to operate, it is simple to the spring for valve compaction tool of assembling.
Its technical scheme is as follows:
A kind of spring for valve compaction tool, including stud, this stud is sequentially installed with support, stop post, packing ring and nut from the bottom up, the side of described stop post is provided with pivoted arm, this pivoted arm be arranged below inverted U-shaped draw-in groove, the lower end of described pivoted arm is connected to chuck, and this chuck hub is provided with perforation. It is so designed that, adopt rotation theory, when assembling, the angle to rotate stop post changes the position dismounting spring for valve, flat surface contact manner by stop post Yu 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 lower section at these support two ends is each provided with a fixed block. It is so designed that, it is possible to inspiration spring compression instrument is better fixed.
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. It is so designed that, makes overall structure more firm.
Beneficial effect:
The spring for valve compaction tool of above technical scheme, adopt rotation theory, when assembling, the angle to rotate stop post changes the position dismounting spring for valve, flat surface contact manner by stop post Yu 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 instrument and can tear the purpose of multiple air valve open, decrease the installation number of times of instrument, improve work efficiency, avoid the danger that press mounting tool landing occurs when dismounting simultaneously, easy to carry, simple to operate, it is easy to assembling.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
Spring for valve compaction tool as depicted in figs. 1 and 2, including stud 5, the lower end of this stud 5 is provided with rounded corner, convenient installation, described stud 5 is sequentially installed with support 1, stop post 2, packing ring 3 and nut 4 from the bottom up, and described support 1 is strip, and along the symmetrical distribution of stud 5, the lower section at these support 1 two ends is each 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 lower section of support 1, pivoted arm 21 is arranged below inverted U-shaped draw-in groove 210, the lower end of this U-shaped draw-in groove 210 is connected to chuck 22, this chuck 22 is provided centrally 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, by fastening nut 4, spring for valve is compressed, 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. Simultaneously, it is possible to the angle rotating stop post 2 changes the position of dismounting spring for valve, play filling instrument and can tear the purpose of multiple air valve open, decrease the installation number of times of instrument.
