Abstract
The utility model discloses a kind of positioning pin and knocks in mechanism, for the positioning pin (1) being knocked in the pin hole (5) of workpiece (2), it includes guide pad (3), the locating piece (6) that is connected between guide pad (3) and workpiece (2) and the stamp (4) that the positioning pin (1) is knocked in pin hole (5), the guide pad (3) offers pilot hole (7), the guide pad (3) after being connect with workpiece (2) by locating piece (6) pilot hole (7) be aligned with the pin hole (5).It is simple, easy to use that the positioning pin of the utility model knocks in mechanism structure, easily positioning pin can be loaded vertically into pin hole and will not the installation such as run-off the straight it is bad the phenomenon that, it needs to install the situation of multiple positioning pins especially suitable for workpiece surface, can work and improve efficiency, save the time.
Description
Technical field
The utility model is related to a kind of positioning pins to knock in mechanism.
Background technology
Positioning pin is very common in machinery, due to its connection with hole frequently with interference fit or transition coordinate, because
This its certain difficulty is installed, need larger strength that can just make in its load hole.In factory's practical operation, often use
The mode that hammer taps, at this point, 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 for drawbacks described above of the prior art, a kind of positioning pin is provided and knocks in mechanism,
In the loading workpiece for enabling positioning pin vertical, will not run-off the straight the phenomenon that.
To realize above-mentioned purpose of utility model, the utility model employs following technical solution：A kind of positioning pin knocks in machine
Structure for the positioning pin to be knocked in the pin hole of workpiece, including guide pad, is connected between guide pad and workpiece and determines
Position part and the stamp that the positioning pin is knocked in pin hole, the guide pad offer pilot hole, the guide pad and workpiece
The pilot hole is aligned with the pin hole after being connected by locating piece.
In addition, the utility model also proposes following attached technical scheme：
The locating piece is pin or the positioning column voluntarily processed.
The positioning column one is spherical in shape.
The locating piece is bolt.
Described stamp one end is provided with pressure end, and the pressure end can be stretched into the pilot hole.
Shock absorbing ring is arranged in the pressure end.
The damping loop material is rubber.
Compared with the prior art, the utility model has the advantage of：The positioning pin of the utility model knocks in mechanism structure letter
It is single, easy to use, it may be convenient to by positioning pin be loaded vertically into pin hole and will not the installation such as run-off the straight it is bad the phenomenon that,
It needs to install the situation of multiple positioning pins especially suitable for workpiece surface, can work and improve efficiency, save the time.
Description of the drawings
Fig. 1 is the structure diagram that the utility model positioning pin knocks in mechanism.
Specific embodiment
Technical solutions of the utility model are made below in conjunction with preferred embodiment and its attached drawing further unrestricted detailed
Explanation.
As shown in Figure 1, knock in mechanism corresponding to a kind of positioning pin of preferred embodiment of the utility model, for by positioning pin
In 1 installation to the pin hole 5 of workpiece 2, including guide pad 3, locating piece 6 and stamp 4.
Offer pilot hole 7 and mounting hole 11 on guide pad 3, the hole of the pin hole 5 on the Kong Weiyu workpiece 2 of pilot hole 7
Position is consistent.Connecting hole 12 is further opened on workpiece 2, pilot hole 7 cooperates with connecting hole 12.
Locating piece 6 is connected between mounting hole 11 and connecting hole 12, and when connecting hole 12 is threaded hole, locating piece 6 is preferred
For bolt, when connecting hole 12 is unthreaded hole, locating piece 6 is preferably pin or the positioning column 8 voluntarily processed, and the one of positioning column 8
End can be set to hemispherical, facilitates and carries out installation guiding.When guide pad 3 is connected to by locating piece 6 on workpiece 2, pilot hole 7
It is aligned with pin hole 5.The diameter of pilot hole 7 is slightly larger than the diameter of positioning pin 1, and positioning pin 1 can be placed in pilot hole 7.
Stamp 4 one is provided with pressure end 9, and the diameter of pressure end 9 is slightly less than the diameter of pilot hole 7, can stretch
Enter in pilot hole 7.Shock absorbing ring 10 is arranged in pressure end 9, shock absorbing ring 10 is preferentially made of rubber material, can prevent stamp
4 damage, while can reduce the generation of noise when striking down with the directly shock of guide pad 3.
When knocking in mechanism using this positioning pin, first guide pad 3 with workpiece 2 by locating piece 6 is connected with each other, is positioned, so
Positioning pin 1 to be tapped is fitted into pilot hole 7 afterwards, positioning pin 1 is tapped using stamp 4, positioning pin 1 can be made to be packed into pin hole
In 5.Due to there is a guiding role of pilot hole 5 in installation process, in the loading workpiece 2 that positioning pin 1 can be vertical, will not incline
Tiltedly.When 2 surface of workpiece have multiple positioning pins need installation when, guide pad 3 need to only be installed with workpiece 2 once can be completed it is multiple fixed
The installation of position pin.
It is simple, easy to use that the positioning pin of the utility model knocks in mechanism structure, it may be convenient to vertically fill positioning pin
Enter in pin hole and will not the installation such as run-off the straight it is bad the phenomenon that, need that multiple positioning pins are installed especially suitable for workpiece surface
Situation, can work improve efficiency, save the time.
It should be pointed out that above-mentioned preferred embodiment is only to illustrate the technical concepts and features of the utility model, purpose
It is the content for allowing person skilled in the art that can understand the utility model and implements according to this, can not this reality be limited with this
With novel protection domain.All equivalent change or modifications substantially made according to the spirit of the present invention, should all cover in this reality
Within novel protection domain.
