Description
Technical Field
The invention belongs to the technical field of mechanical assembly, and relates to a double-end stud disassembling tool.
Background
In industrial application, especially in aeroengine application, connecting fastener has used double-end stud in a large number, and double-end stud is different from general bolt stud, and its structure has decided that ordinary instrument can't the dismouting, adopts instrument clamping screw to carry out the dismouting usually, and at the in-process of dismouting, the clamp force directly acts on the screw thread, often can produce the destruction to the screw thread, or can't grasp the stud, and this makes the dismouting of double-end stud become for a work heavy and difficult.
Disclosure of Invention
The invention aims to provide a double-ended stud disassembling and assembling tool, which can be used for disassembling and assembling studs by converting rotating force into pretightening force of bolts on internal threads of sleeves by rotating a handle and protecting the threads in the disassembling and assembling process.
In order to achieve the above purpose, the invention provides the following technical scheme:
a double-head stud disassembling tool comprises a stud support 1, a rotating handle 2, a fixed handle 3, a limiting pin 4 and a threaded sleeve 5; the stud support column 1, the rotating handle 2 and the limiting pin 4 form a rotating part, the fixed handle 3 and the threaded sleeve 5 form a fixed part, and the fixed part and the rotating part are coaxial; the section of the stud support pillar 1 is T-shaped, and the stud support pillar is an integrated structure consisting of an installation platform and a support rod, and the side surface of the support rod is provided with a threaded hole; the rotary handle 2 is arranged on an installation platform at the upper part of the stud support pillar 1, and the stud support pillar 1 is externally sleeved with a threaded sleeve 5; the fixed handle 3 is arranged at the upper end of the threaded sleeve 5, the side wall of the threaded sleeve 5 is provided with an inclined sliding groove, and the sliding groove is inclined in the vertical direction; the limiting pin 4 is arranged on a mandril threaded hole of the stud mandril 1 through a sliding groove on the threaded sleeve 5, and the axis of the limiting pin 4 is vertical to the axis of the stud mandril 1; the stud support 1, the limit pin 4 and the threaded sleeve 5 form a locking mechanism, and an internal thread matched with the double-head stud is arranged in the lower end of the threaded sleeve 5. The invention has the beneficial effects that:
1. by utilizing the matching of the sliding groove and the limiting pin, the rotating handle is rotated clockwise when the stud is screwed, and the operations of clamping and screwing in the stud are simultaneously completed; after the screwing is completed, the handle is rotated anticlockwise, namely the threaded sleeve is withdrawn, the stud and the tool are separated, and the operation is easy.
2. One end of the stud is clamped by increasing the pretightening force of one end, so that the stud is prevented from being damaged by clamping threads by using a clamp tool, and the reusability of the stud is improved.
3. The size of the tool is suitable, the tool is suitable for operation in a narrow area, and the operation can be completed by one hand.

Detailed Description
The invention is described in detail below with reference to the figures and examples.
The invention provides a double-head stud disassembling tool which has the characteristics of simple and reliable structure, low manufacturing cost and convenience in operation. According to different sizes of target stud, the sleeve is replaced to act on different bolts.
As an embodiment of the invention, the invention provides a double-ended stud disassembling tool which comprises a stud support 1, a rotating handle 2, a fixed handle 3, a limit pin 4 and a threaded sleeve 5; the stud support column 1, the rotating handle 2 and the limiting pin 4 form a rotating part, the fixed handle 3 and the threaded sleeve 5 form a fixed part, and the fixed part and the rotating part are coaxial; the section of the stud support pillar 1 is T-shaped, and the stud support pillar is an integrated structure consisting of an installation platform and a support rod, and the side surface of the support rod is provided with a threaded hole; the rotary handle 2 is arranged on an installation platform at the upper part of the stud support pillar 1, and the stud support pillar 1 is externally sleeved with a threaded sleeve 5; the fixed handle 3 is arranged at the upper end of the threaded sleeve 5, the side wall of the threaded sleeve 5 is provided with an inclined sliding groove, and the sliding groove is inclined in the vertical direction; the limiting pin 4 is arranged on a mandril threaded hole of the stud mandril 1 through a sliding groove on the threaded sleeve 5, and the axis of the limiting pin 4 is vertical to the axis of the stud mandril 1; the stud support 1, the limit pin 4 and the threaded sleeve 5 form a locking mechanism, and an internal thread matched with the double-head stud is arranged in the lower end of the threaded sleeve 5.
The implementation steps of the invention are as follows: 1. the fixing handle 3 is connected with the threaded sleeve 5, a countersunk bolt hole is formed in one end of the fixing handle 3, an internal thread hole for installation is formed in the upper side of the threaded sleeve 5, and the fixing handle 3 and the threaded sleeve 5 form a fixing part through an installation bolt.
2. Insert stud fore-set 1 in the fixed part from threaded sleeve 5 top, rotatory stud fore-set 1 makes the screw hole of ejector pin part coincide with the spout on the threaded sleeve 5 mutually, inserts spacer pin 4 in the spout outside the threaded sleeve 5 to the screw in of ejector pin is downthehole. The outer side of the limit pin 4 is cut with a square end, and is conveniently screwed down by using a clamp tool.
3. And screwing the rotating handle 2 into the threaded hole at the upper end of the stud support 1 to finish the assembly of the tool.
When the double-head stud disassembling tool is used for installing a double-head stud, the rotating handle 2 is firstly rotated to the maximum angle, the stud support pillar 1 is lifted to the highest point, and then the lower end of the threaded sleeve 5 is screwed into the double-head stud to be installed to the required depth. Because the bigger fit clearance that the internal thread adopted, install the double-end stud in the instrument easily. The hand is held tight rotatory handle 2 and fixed handle 3, accomplishes the clamp of stud and instrument and tightly, after aiming at the mounting hole with the other end of stud, rotates rotatory handle 2, screws up the stud to the target hole downthehole, because spout and spacer pin 4 combined action, when clockwise rotation handle 2, can lock the double-end stud, with the other end of moment transmission to the stud, in the screw in target hole. After the screwing is completed, the fixed handle 3 is fixed, the rotating handle 2 is rotated anticlockwise, the sliding groove drives the limiting pin 4 to enable the stud support 1 to be lifted while rotating, the locking force between the stud and the disassembling tool is removed, and the tool is separated from the stud.
When the stud is to be removed, the knob 2 is first rotated to the maximum angle and then the threaded sleeve 5 is mounted at the end of the stud to be removed. After screwing, the instantaneous needle rotates the rotating handle 2, the fixed handle 3 and the rotating handle are tightly held, and the stud ejection column 1 compresses the stud when the handle is tightly held, so that great stud pre-tightening force is provided; then the fixed handle 3 and the rotating handle 2 are rotated to unscrew the stud from the connected piece. And loosening the rotating handle 2 and rotating anticlockwise to separate the tool from the stud to finish the disassembly.
