In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of disassembling positioning pin accessory, bag
Include pull bar 1, gland 2, help pull a cart 3, anti-rotation handle 4 and straight pin 5.
The profile of gland 2 is cylindric, the center drilling of gland upper end；The side of the upper end of gland 2 is connected with anti-rotation handle 4；
The lower end of gland 2 has an opening, and open interior installation helps pull a cart 3, and is available for helping pull a cart and 3 moves up and down；The symmetrical position in lower end two sides of gland 2
Install and be equipped with mounting hole；
The outer-hexagonal bolt of pull bar 1 one, is located in the center drilling of the upper end of gland 2；The upper end of pull bar 1 is outer-hexagonal head,
Lower head has flange face；The lower end of pull bar 1 is screwed cylinder, and upper end is polished rod.
Help pull a cart and 3 be provided with the cylinder of stepped hole for bottom, 3 upper end center of helping pull a cart has the screwed hole of an insertion, and with drawing
Bar 1 is connected through a screw thread；The 3 upper end both sides symmetric position of helping pull a cart is provided with pin-and-hole, for installing straight pin 5；The one end of straight pin 5 with
The mounting hole of gland 2 coordinates, and the other end is connected with 3 interference of helping pull a cart.
When turning pull bar 1 and rotating, by pull bar 1 and help pull a cart 3 screw thread pair relative motion, pass through straight pin 5
Limitation is helped pull a cart in the presence of rotation, and under the active force of screw thread pair relative motion, help pull a cart 3 moves up in gland 2；
Help pull a cart 3 lower ends stepped hole it is in a shape of big-top and small-bottom, stepped hole side outer wall formed a breach, for entangle will
The positioning pin head part of dismounting.
Disassembling positioning pin accessory of the present utility model can realize fast quick-detach alignment pin, and unloading process is simple, time saving, province
Power, and it is simple in construction, using convenient and reliable operation, the defects of solving in the prior art, improve correction efficiency.
