Furthermore, a rod body movable groove and a tailstock movable groove are formed in the sliding hammer rod, and anti-skidding grains are arranged on the outer side surface of the sliding hammer rod.
Further, the rod body movable groove is formed in the lower end of the interior of the sliding hammer rod, the tailstock movable groove is formed in the upper end of the interior of the sliding hammer rod, and the rod body movable groove is communicated with the tailstock movable groove.
Furthermore, a tailstock is arranged at the top end of the pin pulling rod, and the radial size of the tailstock is larger than that of the pin pulling rod body.
Further, the radial dimension of the shaft moving groove is smaller than that of the tailstock, and the dimension of the tailstock moving groove is larger than that of the tailstock.
Furthermore, the lower end of the pin pulling rod is provided with an anti-falling seat, and the anti-falling seat is arranged between the pin pulling connecting piece and the hammer sliding rod.
Further, the size of the pin pulling connector is not unique, and the size and shape of the lower end of the pin pulling connector are selected according to the pin cap structure of the positioning pin.
Through adopting above-mentioned technical scheme, select suitable pulling pin connecting piece according to the nut structure of locating pin, will pull pin connecting piece and locating pin and be connected, pull pin pole itself can dismantle with pulling pin connecting piece and be connected, through the mode that removes the slide hammer pole, with the help of the tail stock that the slide hammer pole was constantly beaten on the pulling pin pole, slowly extract the locating pin in the work piece hole, and is simple and convenient.

FIG. 2 is an exploded view of the pull-out type manual pin puller according to the present invention;
fig. 3 is a sectional schematic view of the sliding hammer rod structure of the present invention;
in the figure: 1. pulling the pin rod; 11. a tailstock; 12. an anti-drop seat; 2. a ram rod; 21. a rod body movable groove; 22. a tailstock movable groove; 3. a pin pulling connecting piece.
Detailed Description
Examples
The present invention will be described in further detail with reference to the accompanying fig. 1-3.
The utility model provides a pull out manual pin puller of formula, is including pulling out pin rod 1, smooth hammer stem 2 and pulling out pin connecting piece 3, it passes to pull out pin rod 1 smooth hammer stem 2, the upper end of pulling out pin rod 1 with smooth hammer stem 2 sliding connection, the lower extreme of pulling out pin rod 1 with 3 threaded connection of pulling out pin connecting piece.
A rod body movable groove 21 and a tailstock movable groove 22 are formed in the sliding hammer rod 2, and anti-skidding grains are arranged on the outer side face of the sliding hammer rod 2.
The rod body moving groove 21 is formed in the lower end of the interior of the hammer slide rod 2, the tailstock moving groove 22 is formed in the upper end of the interior of the hammer slide rod 2, and the rod body moving groove 21 is communicated with the tailstock moving groove 22.
The top end of the pin pulling rod 1 is provided with a tailstock 11, and the radial size of the tailstock 11 is larger than that of the pin pulling rod 1.
The radial dimension of the shaft moving groove 21 is smaller than the radial dimension of the tailstock 11, and the dimension of the tailstock moving groove 22 is larger than the radial dimension of the tailstock 11.
The lower end of the pin pulling rod 1 is provided with an anti-drop seat 12, and the anti-drop seat 12 is arranged between the pin pulling connecting piece 3 and the hammer slide rod 2.
The size of the pin pulling connecting piece 3 is not unique, and the size and the shape of the lower end of the pin pulling connecting piece 3 are selected according to the pin cap structure of the positioning pin.
The working principle is as follows: the pin pulling connecting piece 3 is arranged at the tail end of the pin pulling rod 1, the device is connected with the positioning pin through the pin pulling connecting piece 3, at the moment, one hand holds the anti-falling seat 12, the other hand holds the sliding hammer rod 2, and the sliding hammer rod 2 is pulled up and down continuously and repeatedly, because the size of the rod body movable groove 21 only can pass through the rod body of the pin pulling rod 1, but the tail seat 11 of the pin pulling rod 1 cannot pass through, in the process that the sliding hammer rod 2 moves up and down, the bottom of the tail seat movable groove 22 in the sliding hammer rod 2 continuously impacts the tail seat 11 to generate an upward force, the upward force is transmitted to the pin pulling connecting piece 3 arranged on the rod body through the pin pulling rod 1 and then transmitted to the positioning pin, so that the outward pulling force is continuously applied to the positioning pin, the positioning pin is slowly pulled up, and the positioning pin can be completely separated from a workpiece hole after the positioning.
It should be noted that the present embodiment is only for explaining the present invention, and it is not a limitation of the present invention, and those skilled in the art can make modifications to the present embodiment as necessary without inventive contribution after reading the present specification, but all are protected by patent law within the scope of the claims of the present invention.
