Abstract
The invention discloses an internal threaded pin which comprises a pin body (3). The internal threaded pin is provided with a through hole (32) which extends along the axial direction and penetrates through the pin body (3), and the partial inner wall, close to the exterior of a pin hole (4), of the through hole (32) is provided with an internal thread; and when the internal threaded pin is installed, gas in the pin hole (4) is discharged from the through hole (32), and the phenomenon that the gas in the pin hole (4) is compressed by the pin body (3) so as to generate resistance for installing the internal threaded pin can be avoided, therefore, the labor intensity for installing the internal threaded pin is further reduced; and the two ends of the internal threaded pin are provided with chamfers (33).
Description
Technical field
The present invention relates to mechanical assembling and positioning device technique field, particularly a kind of internal thread pin.
Background technique
The internal thread pin has cylindrical pin with internal thread and taper pin with internal thread.
Cylindrical pin with internal thread is a kind of of straight pin.Straight pin is a kind of be used for location or connection, relies on interference fit to be fixed on the device in the pin-and-hole.Usually do not receive load when straight pin is used to locate or receive very little load, quantity is no less than two, is distributed on the integrally-built symmetry direction of connected piece, and farther apart is good more, and the length of pin in each connected piece is about 1-2 times of shank diameter.
Taper pin with internal thread is a kind of of taper pin.Taper pin has 1: 50 tapering, and self-locking performance is good, and Location accuracy is high, and is easy for installation, repeatedly installs and removes the influence of Location accuracy lessly, is mainly used in the location, also can connect pin.
Shown in the mounting structure schematic representation of internal thread pin in Fig. 1 existing technology; The now normal internal thread pin that uses is only near the outside end axial aperture 01 of pin-and-hole 4; At the end near pin-and-hole inside is solid-end 02; Like this when the internal thread pin is installed, the gases in the pin-and-hole 4 can't be discharged and received the compression of shank solid-end 02, thereby internally the installation of threaded has produced resistance; Need increase the labor intensity of mount pin, thereby the installing force that further increases is damaged pin-and-hole seat 1 and 2 easily for this reason.
Summary of the invention
In view of this, the invention provides a kind of novel internal thread pin that reduces the installation labor intensity of internal thread pin.
This internal thread pin is used to be installed in the pin-and-hole, it is characterized in that, comprises shank, said shank have one in axial direction extend and run through said shank through hole, the inwall of said through hole has internal thread.
Further, said through-hole aperture is to successively decrease to being cascade towards the inner end of pin-and-hole from the end of said shank towards box outer.
Further, the internal thread in the said through hole is distributed in the part of through-hole wall near box outer.
Further, said shank is that external diameter can the micro-shank that shrinks.
Further, there is chamfering said shank end.
Further, said shank is shaped as cylindrical body or cone.
A kind of internal thread pin provided by the present invention since have one in axial direction extend and run through said shank through hole; Like this when the internal thread pin is installed; The pin-and-hole gas inside can be discharged through through hole, thereby has avoided gas to receive the installation generation resistance that shank compresses internal threaded.Therefore, the present invention has reduced the labor intensity that the internal thread pin is installed.
Description of drawings
Fig. 1 is the mounting structure schematic representation of the internal thread pin of existing technology;
Fig. 2 is the mounting structure schematic representation of the internal thread pin of embodiment one.
Embodiment
Core of the present invention provides a kind of internal thread pin, and this internal thread pin comprises shank, shank have one in axial direction extend and run through shank through hole, the inwall of through hole has internal thread.When the internal thread pin was installed, the gas in the pin-and-hole was discharged by through hole, had avoided the interior gas of pin-and-hole to receive the installation generation resistance that shank compresses internal threaded, thereby, further reduced the labor intensity that the internal thread pin is installed.
In order to make those skilled in the art person understand the present invention program better, the present invention is done further detailed description below in conjunction with accompanying drawing and embodiment.
Embodiment is just like Fig. 2, positions with inner pinhole seat 2 through internal thread pin 3 external pin-and-hole seats 1 to be connected.
The internal thread pin of this mode of execution has tubular shank 31.Can find out that by Fig. 1 the external diameter of shank 31 is a bit larger tham the diameter of pin-and-hole 4 column parts, straight pin is fixed in the pin-and-hole 4 by interference fit.This internal thread pin have one in axial direction extend and run through shank through hole 32, through hole 32 has been communicated with pin-and-hole inside and box outer.Like this, in installation internal thread pin 3, the gas in the pin-and-hole 4 is discharged by through hole 32, has avoided the interior gas of pin-and-hole to receive shank 31 compressions and the installation generation resistance of internal threaded.
Successively decrease to being cascade towards the inner end of pin-and-hole from the end of shank 31 towards box outer in the aperture of through hole 32, such design can reduce the amount of deformation of shank when the internal thread pin is installed.Through hole 32 has internal thread on the inwall near the part of box outer, if cooperate being bolted in the through hole 32 of internal thread with one, the part of utilizing bolt to expose through hole 32 can be extracted the internal thread pin from pin-and-hole 4.The two ends of this internal thread pin also have chamfering 33.
It is cylindrical internal thread pin that a kind of shank is provided in the above-described embodiment, and when shank when not being cylindrical, the technological scheme of technical solution problem of the present invention stands good when being cone such as shank.
The similar of the internal thread pin that the structure of the internal thread pin that embodiment two is introduced and embodiment one are introduced is the cone that is shaped as of shank.The shank of the internal thread pin that this mode of execution relates to is for having the cone of 1: 50 tapering.This internal thread pin have one in axial direction extend and run through shank through hole, when the internal thread pin was installed, the gas in the pin-and-hole was discharged by through hole, had avoided gas in the pin-and-hole to receive the installation that shank compresses internal threaded and had produced resistance.Successively decrease to being cascade towards the inner end of pin-and-hole from the end of shank towards box outer in the aperture of said through hole, such design can reduce the amount of deformation of shank when the internal thread pin is installed.Through hole has internal thread on the inwall near box outer, if cooperate being bolted in the through hole of internal thread with one, the part of utilizing bolt to expose through hole can be extracted the internal thread pin from pin-and-hole.The two ends of this internal thread pin also have chamfering.
Used concrete example among this paper principle of the present invention and mode of execution are set forth, above embodiment's explanation just is used for helping to understand method of the present invention and core concept thereof.Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of invention claim.
