Abstract
The utility model discloses a fastening device of an air valve core. The fastening device of the air valve core comprises a base, a power device fixedly connected with the base, a sleeve pipe fixedly connected with the base, a built-in two-cone chuck and a machine head of an elastic piece. The sleeve pipe is connected with the two-cone chuck in a sleeved mode. A front cone portion of the two-cone chuck is attached tightly with an inner wall of the machine head. A front end of a second top rod is attached tightly with a tail end of the two-cone chuck. A front end of a first top rod is attached tightly with a tail end of the air valve core in the two-cone chuck. The second top rod is sleeved with the sleeve pipe in a flexible mode. The first top rod is sleeved with the second top rod in a flexible mode. The first top rod and the second top rod are driven by the power device. According to the problems of the prior art, the fastening device of the air valve core is provided. The fastening device of the air valve core is simple in structure. Clamping the air valve core when the air valve core is needed to be machined can be achieved. Loosening the air valve core and releasing the air valve core after the air valve core is machined.
Description
Technical field
The utility model relates to a kind of valve inside fastener.
Background technology
Valve inside is a kind of vitals of engine, waste gas after being responsible in engine input air specially and discharging burning, from engine structure, be divided into inlet valve core and exhaust valve core, the effect of inlet valve core is with in the air intake engine, burn with fuel mix, the effect of exhaust valve core is that the waste gas after the burning is discharged and heat radiation, therefore the effect of valve inside in transmitter is apparent, in actual processing process, product there is very high requirement, need to carry out many PROCESS FOR TREATMENT to valve inside, yet, lack a kind of device that can tighten up valve inside in the prior art, need artificial participation so that each valve inside processed, not only human cost increases, and efficient is extremely low, needs improvement badly.
The utility model content
For the problem that prior art exists, the purpose of this utility model is to propose a kind of valve inside fastener, and is simple in structure, can realize namely clamping valve inside, after machining when adding man-hour to valve inside, namely unclamp valve inside, and discharge valve inside.
For reaching this purpose, the utility model by the following technical solutions:
A kind of valve inside fastener, comprise pedestal, be fixedly connected with the power set of described pedestal, be fixedly connected with the sleeve pipe of described pedestal, built-in bipyramid chuck, the head of elastic component, described sleeve pipe is socketed described bipyramid chuck, described bipyramid chuck chamfered section is adjacent to described head inwall, the second push rod front end is adjacent to described bipyramid chuck tail end, the first push rod front end is adjacent to valve inside tail end in the described bipyramid chuck, described the second push rod telescopic is connected in the described sleeve pipe, described the first push rod telescopic is connected in described the second push rod, described the first push rod, described the second push rod is moved in described power set
Be subjected to the power of described the second push rod, described bipyramid chuck clamps described valve inside;
Be subjected to the power of described elastic component, described bipyramid chuck unclamps described valve inside;
Be subjected to the power of the first push rod, described valve inside can be pushed.
Described the second push rod front end is offered the groove that cooperates with tapering behind the described bipyramid chuck.
Based on disclosing of above technical scheme, the utlity model has following beneficial effect:
The utility model is simple in structure, can realize namely clamping valve inside when adding man-hour to valve inside, after machining, namely unclamps valve inside, and discharges valve inside.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1:
Wherein: 1, bipyramid chuck; 2, head; 3, elastic component; 4, the first push rod; 5, the second push rod; 6, valve inside; 7, pedestal.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment:
A kind of valve inside fastener is proposed, comprise pedestal 7, be fixedly connected with the power set of pedestal 7, be fixedly connected with the sleeve pipe of pedestal, built-in bipyramid chuck 1, the head 2 of elastic component 3, sleeve pipe socket bipyramid chuck 1, bipyramid chuck 1 chamfered section is adjacent to head 2 inwalls, the second push rod 5 front ends are adjacent to bipyramid chuck 1 tail end, the first push rod 4 front ends are adjacent to bipyramid chuck 1 interior valve inside 6 tail ends, the second push rod 5 telescopics are connected in the sleeve pipe, the first push rod 4 telescopics are connected in the second push rod 5, the first push rod 4, the second push rod 5 is moved in power set
Be subjected to the power of the second push rod 5, bipyramid chuck 1 clamps valve inside 6;
Power set drive the second push rod 5, be subjected to the power of the second push rod 5, bipyramid chuck 1 chamfered section compresses head 2 inwalls, head 2 inwalls then apply reaction force in bipyramid chuck 1, under the radial component effect of reaction force, to make bipyramid chuck 2 inwalls clamp valve inside 6, in like manner, the groove interaction of bipyramid chuck 1 rear tapering and the second push rod 5 front ends impels bipyramid chuck 2 to clamp valve inside 6 equally, after valve inside 6 is clamped, namely can process valve inside 6 by some equipment.
After valve inside 6 machines, power set stop to drive the second push rod 5, the second push rods 5 no longer exerts pressure to bipyramid chuck 1, and bipyramid chuck 1 is subjected to elastic component elastic force, be applied on the bipyramid chuck 1 so that no longer include radial component, so that bipyramid chuck 1 unclamps valve inside 6;
Power set drive the first push rod 4, are subjected to the axial thrust of the first push rod 4, and valve inside 6 will break away from bipyramid chuck 1.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
