Description
Technical field
It the utility model is related to a kind of positioning pin and knock in mechanism.
Background technology
Positioning pin is very common in machinery, since the connection in itself and hole coordinates frequently with interference fit or transition, because
This its certain difficulty is installed, it is necessary to which larger strength can just make in its load hole.In factory's practical operation, often use
The mode that hammer taps, at this time, positioning pin axis and the axis in hole cannot be guaranteed on one wire during due to human hand held positioning pin,
Often it is askew there is a situation where striking, influence part installation accuracy, even result in part rejection, and this kind of mode be easier to pound it is in one's hands,
There is certain security risk.
Utility model content
The purpose of this utility model is that it is directed to drawbacks described above of the prior art, there is provided one kind can be vertical by positioning pin
The positioning pin knocked in dowel hole knocks in mechanism.
To realize above-mentioned purpose of utility model, the utility model employs following technical solution：A kind of positioning pin knocks in machine
Structure, including body and transmission rod are oriented to, described guiding body one end offers pilot hole, and the other end offers and the pilot hole
The prepackage hole communicated, the transmission rod are slidably installed in the pilot hole, and described transmission rod one end is provided with and can stretch into
The power transmission portion in the prepackage hole, the prepackage hole are used to accommodate the positioning pin.
In addition, the utility model further includes following attached technical scheme：
The guiding body and the transmission rod are in cylinder.
The positioning pin knocks in mechanism and further includes the clump weight for being connected to described transmission rod one end.
The air hole communicated with the pilot hole is further opened with the guiding body.
Compared with the prior art, the utility model has the advantage of：The positioning pin of the utility model knocks in mechanism, its structure
Simply, install, is easy to use, ensure that positioning pin is vertically knocked in hole, will not strike situations such as askew, and be not easy to knock
Finger.In addition, the installation of the positioning pin for human hand recessed inside parts not easy to install, also can be fine using the utility model
Installation.
Brief description of the drawings
Fig. 1 is the structure diagram that the utility model positioning pin knocks in mechanism.
Fig. 2 is that the utility model positioning pin knocks in the structure diagram that mechanism installs clump weight additional.
Fig. 3 is that the utility model uses schematic diagram.
Embodiment
Technical solutions of the utility model are made below in conjunction with preferred embodiment and its attached drawing further nonrestrictive detailed
Explanation.
As shown in Figure 1 to Figure 2, a kind of preferred embodiment of mechanism is knocked in corresponding to the utility model positioning pin, it includes：
It is oriented to body 1, transmission rod 2.It is oriented to 1 one end of body and offers the pilot hole 3 for leading to inside, the other end offers and pilot hole 3
Interconnected prepackage hole 4, the diameter in prepackage hole 4 are slightly larger than the diameter for the positioning pin 6 to be assembled.Transmission rod 2, which is installed on, leads
Into hole 3, it can be slided along pilot hole 3, and 2 one end of transmission rod is additionally provided with power transmission portion 2a, and the diameter of power transmission portion 2a is than prepackage
The diameter in hole 4 is small, it can be stretched into prepackage hole 4, when preferably transmission rod 2 stretches into the extreme position in prepackage hole 4, power transmission portion 2a
End face be oriented to body 1 end face it is concordant.
Transmission rod 2 is tapped for convenience of people and increases impact force, which, which knocks in mechanism, can also install clump weight 5, institute additional
State clump weight 5 with transmission rod 2 to be connected, offer the mounting hole 7 slightly larger than 2 section of transmission rod thereon, during connection, by transmission rod 2
It is inserted into mounting hole 7.
As shown in figure 3, this positioning pin knocks in mechanism when installing positioning pin 6, first need to positioning pin 6 to be mounted fill in it is pre-
Fill in hole 4, then press down the location hole 9 in 6 alignment pieces 10 of positioning pin, the hand-held body 1 that is oriented to so that positioning pin 6 supports
Transmission rod 2 is played, since the end face for being oriented to body 1 is plane, it is bonded to each other with 10 surface of workpiece, can ensure positioning pin 6 at this time
The axis of axis and location hole 9 be located substantially on a straight line.With hammer tap clump weight 5 (if not installing clump weight 5,
Tap transmission rod 2), impact force is passed to positioning pin 6 by transmission rod 2, and positioning pin 6 will be pressed into location hole 9, due to leading
It is bonded to the end face of body 1 with 10 surface of workpiece, therefore positioning pin 6 will not strike askew, ensure that accuracy, be oriented to the end of body 1
Face can also suitably do the cooperation area bigger greatly, being allowed to the surface of workpiece 8, be less susceptible to tilt.People when being additionally, since percussion
Hand-held to be oriented to body 1, when percussion, is not easy to pound in one's hands.Furthermore, it is contemplated that when transmission rod 2 moves in pilot hole 3, internal gas
It is not easy to discharge, resistance can be increased, therefore, the air hole 1a communicated with pilot hole 3 is offered on body 1 is oriented to, passed with reducing
Power bar 2 is influenced by air pressure during the motion.Air hole 1a is preferably to be arranged at pilot hole 3 to put down with what prepackage hole 4 was connected
On face.
The positioning pin of the utility model knocks in mechanism, its is simple in structure, installs, is easy to use, ensure that positioning pin is vertical
Knock in hole, will not strike situations such as askew, and be not easy to knock finger.In addition, for human hand it is not easy to install recessed zero
The installation of positioning pin inside part, can also be installed well using the utility model.
It is pointed out that above-mentioned preferred embodiment is only to illustrate the technical concepts and features of the utility model, its purpose
The content that is to allow person skilled in the art to understand the utility model is simultaneously implemented according to this, can not limit this reality with this
With new protection domain.All equivalent change or modifications made according to the utility model Spirit Essence, should all cover in this reality
Within new protection domain.
