Abstract
The invention relates to a puncher, comprising a puncher shell; and the front end of the shell is provided with a slideable punching head. The puncher is characterized in that the shell is internally provided with an ejecting rod for pushing the punching head to work and an impacting body; one end of the ejecting rod is contacted and connected with the punching head, the outer diameter thereof is sheathed with a first pre-tensioning spring and the other end thereof is contacted and connected with the impacting body; the section of the impacting body, contacted with the ejecting rod, is provided with a blind hole matched with the ejecting rod for impacting; and the outer diameter of the impacting body is sheathed with a second pre-tensioning spring. The puncher can be used for drilling in the machine building industry, overcomes the defects that the strength is wasted and the speed is slow when a hammer and a sample puncher are adopted to knock for punching, reduces the labor intensity of operators, ensures the processing quality and improves the working efficiency.
Description
Technical field
The present invention relates to a kind of piercer, specifically, the present invention relates to a kind of piercer that machine industry is used.
Background technology
In machine industry, often need on part, hole.Line earlier according to the position of line, is carried out the processing in hole then before the boring with drill bit.But need dash a pitting at the central point of line before boring, promptly locating hole helps the drill bit location, prevents that drill bit from skidding on workpiece, and the position in hole is bored partially.Usually people dash (Fig. 1) and one with a sample hammer is knocked this work of finishing, and are about to sample and dash the most advanced and sophisticated position of aiming at line, knock the other end that sample dashes with hammer, form locating hole.Form like this that locating hole is time-consuming, effort and efficient is low.
Wish has a kind of piercer always, but high efficiency, time saving and energy saving the locating hole of getting.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of piercer, dashes and one hammer is knocked the shortcoming that speed when getting locating hole is slow, waste time and energy to overcome with a sample.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
A kind of piercer, comprise the piercer housing, the housing front end is provided with slidably drift, enclosure interior is provided with push rod and the impact body that promotes drift work, push rod one end and drift touch, and are with first preloading spring on the push rod external diameter, and the other end and the impact body of push rod touch, one section of contacting with push rod of impact body is provided with one and cooperates the blind hole of impacting with push rod, is with second preloading spring on the external diameter of impact body.
Described housing can be made up of clamp body, connector, tail-hood, and clamp body is connected with the connector threaded one end, and tail-hood is threaded with the connector other end.
The openend of described blind hole can be flare.
When adopting technical solution of the present invention, have following beneficial effect:
1. overcome to dash and knocked that punching is bothersome, slow-footed shortcoming with hammer, sample;
2. reduce operator's labour intensity, guaranteed crudy;
3. improved operating efficiency.
Below in conjunction with the drawings and specific embodiments the present invention is described in further details.
Description of drawings
Fig. 1 is that sample is towards schematic diagram.
View when Fig. 2 does not use for piercer of the present invention.
Fig. 3 is the view of piercer of the present invention when second spring is compressed to extreme position.
Fig. 4 impacts the view of moment for piercer of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with accompanying drawing and specific embodiment, further set forth the present invention.
As shown in Figure 2, a kind of piercer comprises piercer housing 1, and described housing 1 is made up of clamp body 11, connector 12, tail-hood 13; Housing 1 front end is provided with slidably drift 2, and described drift 2 is by the 11 one-tenth matched in clearance of jump ring 3 and clamp body on the drift 2; Housing 1 inside is provided with push rod 5 and the impact body 6 that promotes drift work, push rod 5 one ends and drift 2 touch, be with first preloading spring 4 on the push rod external diameter, the other end of push rod 5 and impact body 6 touch, one section of contacting with push rod 5 of impact body 6 is provided with one and cooperates the blind hole 61 of impacting with push rod 5, is with second preloading spring 7 on the external diameter of impact body 6; Clamp body 11 is connected with connector 12 threaded one ends, and tail-hood 13 is threaded with connector 12 other ends.
The openend of described blind hole is a flare.
During use, hold the tail-hood 13 of piercer, with the scribe point on drift 2 alignment pieces of piercer, firmly pushing forward, drift 2 promotes push rod 5 compressions first preloading spring 4 and moves right, and push rod 5 is aligned position and coaxial with impact body 6 gradually gradually by connector 12 guiding.Meanwhile push rod 5 right-hand members slide on the flare 62 of the left end of impact body 6, and promote impact body 6 and move right, and compress second preloading spring 7.
As shown in Figure 3, second preloading spring 7 is compressed the position that reaches capacity, and stores ceiling capacity down.As shown in Figure 4, continue with force compresses drift 2 this moment again, and push rod 5 and impact body 6 reach coaxial, push rod 5 right-hand members enter in the blind hole 61 of impact body 6 left ends, under the effect of second preloading spring 7, impact body 6 is moved to the left rapidly, and the right-hand member end face of push rod 5 is impacted at 61 ends of blind hole of impact body 6 left ends.Drift 2 is subjected to from just go out a pitting after the impulsive force of push rod 5 on workpiece.
After drift 2 left workpiece, under the effect of first preloading spring 4, drift 2 and push rod 5 were moved to the left, and came back to the state of diagram 2.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
