Abstract
A quick-release pin puller comprises a pull rod, a punch hammer, a nut sleeve and a screw, wherein the head of the nut sleeve is provided with an inner opening and an outer opening which have different sizes at the same side, the opening close to the inner side is larger and is matched with the head of the screw, and the opening close to the outer side is smaller and is matched with the screw. The utility model discloses a percussion hammer is to the striking of pull rod and twist the pulling of screw, the nut cover in the pin screw, is dismantled the pin. The nut sleeve is provided with the opening at the head part, so that the screw can be freely assembled and disassembled in the nut sleeve, and the nut sleeve can be continuously disassembled without screwing down and screwing up the nut sleeve from the pull rod, thereby greatly simplifying the operation and improving the working efficiency.
Description
Technical field
The utility model relates to a kind of maintenance of equipment instrument, especially for the quick-release pin removal of dismounting pin.
Background technology
In the maintenance of equipment process, usually need to dismantle continuously a plurality of counterbore pins.Usually adopt a kind of hand-operated tools of pin removal, it is made of pull bar, block stamp, nut sleeve, screw, and during dismounting, elder generation on screw, is screwed in the nut sleeve string in the screw of pin together, nut sleeve is screwed on the pull bar again, utilizes block stamp bump pull bar, extracts pin.And when another pin of dismounting, need again nut sleeve is screwed off from pull bar, unload screw again, repeat said process then, this makes troubles to maintenance work, inefficiency.
The utility model content
The purpose of this utility model is to overcome the weak point of existing pin removal, provides a kind of simplified control, the quick-release pin removal of high efficiency.
The technical solution of the utility model is: the quick-release pin removal is made of pull bar, block stamp, nut sleeve and screw, screw passes the endoporus of nut sleeve head, head of screw is stuck on the step of endoporus, improvements are inside and outside two openings that there are different sizes nut sleeve head the same side, and wherein inner opening is bigger, and width is a bit larger tham the head of screw diameter, highly be a bit larger tham the head of screw height, outer opening is less, and width is a bit larger tham screw diameter, and height is consistent with hole depth in the nut sleeve head.
Further scheme is: inner A/F is consistent with nut sleeve thread Pilot hole diameter, and outer A/F is consistent with nut sleeve head diameter of bore.
Because the nut sleeve head has two openings, make screw in nut sleeve, load and unload freely, so will nut sleeve do not back out and screw on from pull bar, can carry out the dismounting of a plurality of pins continuously, thereby simplify the operation greatly, increase work efficiency.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a nut sleeve head opening part cutaway view.
The specific embodiment
As figure, block stamp 2 is enclosed within on the pull bar 3 in the quick-release pin removal, pull bar is screwed in the tailing screw flight of nut sleeve 1, during screw 4 is packed the endoporus of nut sleeve head into from the opening 5 of nut sleeve head the same side and opening 6, opening 5 width are with the diameter and the degree of depth with nut sleeve head endoporus is consistent highly respectively, opening 6 width are consistent with nut sleeve thread Pilot hole diameter, highly are a bit larger tham the head of screw height.
Claims (2)
1, a kind of quick-release pin removal, constitute by pull bar, block stamp, nut sleeve and screw, screw passes the endoporus of nut sleeve head, and head of screw is stuck on the step of endoporus, it is characterized in that there are inside and outside two openings of different sizes nut sleeve head the same side, wherein inner opening is bigger, width is a bit larger tham the head of screw diameter, highly is a bit larger tham the head of screw height, and outer opening is less, width is a bit larger tham screw diameter, and height is consistent with hole depth in the nut sleeve head.
2, by the described quick-release pin removal of claim 1, it is characterized in that inner A/F is consistent with nut sleeve thread Pilot hole diameter, outer A/F is consistent with nut sleeve head diameter of bore.
