Abstract
The invention discloses a hollow dowel opening press mounting tool. The hollow dowel opening press mounting tool comprises a pressing body and a pressing head, wherein the pressing body is of a cylinder structure with big end down step-shaped through holes formed in the middle, a thread is formed on the inner wall of a small-diameter end of each through hole, and the position where the screw thread is formed is one side where the small-diameter end and the large-diameter end are connected; the pressing head is formed by a cone-like expansion part and a cylindrical connecting part, and a screw thread is formed on the outer wall of the connecting part; and the pressing head is put into the middle of the pressing body from the large-diameter end of each through hole, and the connecting part is in thread fit with the small-diameter end of each through hole. The hollow dowel opening press mounting tool disclosed by the invention has the advantages that the expansion of a hollow dowel opening is completed by virtue of a press mounting tool composed of the pressing body and the pressing head, the distance of the pressing head pushing down is controlled by virtue of contact of the bottom of the pressing body and a workpiece, a dowel is avoided being damaged due to excessive expansion of the opening, or the condition that secondary operation needs to be carried out due to small expansion amplitude is avoided, and one-step operation success efficiency is improved.
Description
Technical field
The invention belongs to a kind of installation tool of pin, and in particular to a kind of hollow pin opening press-fits tool.
Background technology
Hollow taper pin as a kind of standardized securing member, when the hinged place for two parts constitutes chain connection,
The opening for expanding hollow taper pin is needed, so that pin will not come off from part.The existing method for expanding hollow taper pin opening
It is the opening of the pressure head alignment pins for using a taper, then with hammer to pressure head applying power, pressure head is pushed so as to expand sky
The opening of heart taper pin.
The distance that the uncontrollable pressure head of this method is pushed, pressure head depression distance greatly ruptures easily opening；Apart from too small
The amplitude of enlarged open can not meet requirement, need secondary operation, affect efficiency, it is impossible to meet the requirement of high-volume operation.
The content of the invention
The present invention proposes to overcome shortcoming present in prior art, its objective is to provide a kind of hollow pin
Opening press-fits tool.
The technical scheme is that：
A kind of hollow pin opening press-fits tool, including laminate and pressure head, and the laminate is the up-small and down-big notch cuttype of intermediate formation
The cylindrical structure of through hole, the miner diameter end inwall of through hole forms one section of screw thread, and is formed at screw thread as miner diameter end and bigger diameter end company
The side for connecing；The pressure head is formed by circular cone build enlarged portion and column type connecting portion, and connecting portion outer wall forms screw thread；The pressure
Head is loaded in the middle of laminate by through hole bigger diameter end, and connecting portion coordinates with through hole miner diameter end screw thread.
The bigger diameter end aperture of the through hole is slightly less than the internal diameter of hollow pin.
Internal diameter of the cone basal diameter of the enlarged portion more than hollow pin.
When the pressure head requires the enlarged open of hollow pin to satisfaction, the bottom of laminate and absorption surface.
The invention has the beneficial effects as follows：
The present invention press-fits the expansion that tool completes hollow pin opening by what laminate, pressure head were constituted, by laminate bottom and workpiece
Contact controlling the distance that pressure head is pushed, it is to avoid by opening excessive enlargement, damage pin, or enlarging amplitude it is too small, need it is secondary
Operation, improves the successful efficiency of one-stop operation.

Specific embodiment
Press-fit tool to hollow pin opening of the present invention with reference to Figure of description and embodiment to be described in detail：
As shown in Fig. 1 ~ 4, a kind of hollow pin opening press-fits tool, including laminate 1 and pressure head 2,
The laminate 1 is the cylindrical structure of the up-small and down-big notch cuttype through hole 11 of intermediate formation, the miner diameter end inwall of through hole 11
One section of screw thread is formed, and forms the side being connected with bigger diameter end for miner diameter end at screw thread；
The pressure head 2 is formed by circular cone build enlarged portion 21 and column type connecting portion 22, and the outer wall of connecting portion 22 forms screw thread, connection
Six side's screws are formed on the top of portion 22；
The pressure head 2 is loaded in the middle of laminate 1 by the bigger diameter end of through hole 11, and connecting portion 22 coordinates with the miner diameter end screw thread of through hole 11.
The bigger diameter end aperture of the through hole 11 is slightly less than the internal diameter of hollow pin 3, certain for ensureing pin and pressure head
Coaxially.
Internal diameter of the cone basal diameter of the enlarged portion 21 more than hollow pin 3.
When the pressure head 2 requires the enlarged open of hollow pin to satisfaction, the bottom of laminate 1 contacts with workpiece 4, so as to
Prevent the depression distance of pressure head 2 excessive.
During the lumen contact of pressure head 2 and hollow pin 3, there is certain distance d between laminate 1 and workpiece 4, it is ensured that to laminate 1
Applying power causes the lower end of laminate 1 that the expansion of the opening of hollow pin 3 is completed when contacting with workpiece 4.
The using method of the present invention：
Size first according to the hollow pin 3 for using, determine suitable axial direction of the pressure head 2 in laminate 1 by installing pad additional
Position, it is ensured that when the bottom of laminate 1 contacts with workpiece 4, pressure head 2 is by the enlarged open of hollow pin 3 to suitable size；Then
Together with pressure head 2 is screwed with laminate 1 using hexagon.
During work, the hollow pin 3 in tool alignment pieces 4 will be press-fited, laminate 1 is stretched in one end of the opening of hollow pin 3
In the macropore of bottom, and contact with the circular cone build enlarged portion 21 of pressure head 2；Then the top applying power of tool is being press-fited（For example with hammer
Son is pounded, or directly pressing etc.）So that laminate 1 is moved down until contact workpiece 4；Laminate 1 is moved down with dynamic head 2, laminate
1 contact with workpiece 4 can control the distance that pressure head 2 is pushed；The cone expansion portion 21 of pressure head 2 expands the opening of hollow pin 3,
Complete one-stop operation.
The present invention completes the expansion of hollow pin opening by the tool that press-fits that laminate, pressure head are constituted, by laminate bottom with
The contact of workpiece is controlling the distance that pressure head is pushed, it is to avoid by opening excessive enlargement, damage pin, or enlarging amplitude it is too small, need
Secondary operation, improves the successful efficiency of one-stop operation.
