Abstract
The utility model relates to a percussion type pin shaft dismounting device, which belongs to a pony-sized pin shaft dismounting device. One end of a bolt is connected with a pin shaft with screw threads and the bolt is connected with a link stopper which moves along the bolt and runs without a mistake upon the pin shaft with screw threads. As the space necessary for the movement of the link stopper is small, the pin shaft can be dismounted conveniently at some narrow places. The utility model has the advantages of simple structure, convenient operation and installation and needs no any auxiliary tool while dismounting the pin shaft and therefore shows a superiority at some narrow places where the pin shaft cannot be dismounted even with the help of some auxiliary tools. Therefore, when designing the structures of machines, reasonably making use of the device makes the structural design more compact.
Description
Technical field
The utility model relates to a kind of attaching/detaching apparatus of small-sized bearing pin, particularly a kind of impacting type bearing pin attaching/detaching apparatus.
Background technology
At present, engineering machinery field at home, the dismounting of some small-sized bearing pins mainly is to finish by hammer and other aid, during dismounting, the workman uses hammer and other instrument to knock bearing pin, bearing pin is pulled down, in narrow and small place, some spaces, when being unable to hold other instrument and hammer, it is very difficult that disassembling and assembling pin shaft just becomes.
Summary of the invention
Even the purpose of this utility model is to provide a kind of in narrow and small place, some spaces, the also impacting type bearing pin attaching/detaching apparatus of disassembling and assembling pin shaft easily.
The purpose of this utility model is achieved in that this bearing pin attaching/detaching apparatus has bolt, collision block and is threaded the bearing pin in hole, and the bearing pin that is threaded the hole is connected an end of bolt, and collision block is sleeved on the bolt.
Beneficial effect: owing to adopt such scheme, end at bolt is connected with screwed bearing pin, on bolt, connect collision block, collision block moves on bolt, impinge upon accurately on the threaded bearing pin, requisite space is little during the collision block motion, can be in narrow and small place, some spaces, disassembling and assembling pin shaft has reached the purpose of this utility model easily.This apparatus structure is simple, use, easy for installation, disassembling and assembling pin shaft need not be by any aid, some use aids also can't the small space of disassembling and assembling pin shaft in, more can demonstrate the superiority of this device, in the design process of some frame for movements, this device of reasonable use can make the compact more of structural design.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
Embodiment 1: this bearing pin attaching/detaching apparatus has bolt 1, collision block 2 and is threaded the bearing pin 3 in hole, and the bearing pin 3 that is threaded the hole is connected an end of bolt 1, and collision block 2 is sleeved on the bolt 1.
During work, the collision block cover is installed on the bolt, and then bolt and bearing pin are bound up, can load onto bearing pin or pull down very easily by the bump of collision block.
Claims (1)
1, a kind of impacting type bearing pin attaching/detaching apparatus is characterized in that: this bearing pin attaching/detaching apparatus has bolt, collision block and is threaded the bearing pin in hole, and the bearing pin that is threaded the hole is connected an end of bolt, and collision block is sleeved on the bolt.
