Abstract

The utility model discloses a taper pin roll dismounting apparatus used in the installation and maintenance of mechanical equipment, namely a special pin roll extractor. The pin roll extractor mainly consists of a handle with one end provided with internal threads, a screw mandrel with the two ends both provided with threads, and an impinger which can be sheathed on the handle. Practices prove that the pin roll extractor has the advantages of simple structure, convenient installation, safety, reliability and strong practicability and can greatly shorten man-hour for examining and fixing the equipment and improve the work efficiency.

Description

The bearing pin extractor
Technical field
The utility model relates to and a kind ofly using in plant equipment installation and maintenance engineering, has the removal tool of tapering bearing pin on the extraction device, specifically is exactly a kind of special-purpose bearing pin extractor.
Background technology
The many plant equipment of China enterprise are when repairing, some parts need dismounting (as bearing block, some wallboards etc.), the matched in clearance of the same bearing block of tapering bearing pin, wallboard taper hole is tighter, remove very difficulty, remove with common instrument, the maintainer has no way of doing it at all, and work brings very big inconvenience to repair and maintenance.
Summary of the invention
The utility model is at above deficiency, and development and design also provides a kind of simple in structure, easy to operate special use instrument of pulling pin, for the quick field-strip equipment of repair and maintenance personnel provides reliable assurance.
The technical scheme that its technical problem that solves the utility model adopts is:
This bearing pin extractor mainly is made up of handle, screw mandrel and beating device.
One end of described handle connects screw mandrel, and the two ends of screw mandrel are all threaded, and handle grip one end can put beating device.
Facts have proved that the utility model apparatus structure is simple, and is easy for installation, safe and reliable, practical, can shorten man-hour of repair apparatus greatly, increase work efficiency.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in the figure, the utility model is mainly by handle 2 that has internal thread and the externally threaded screw mandrel 3 of double end, and the beating device 1 that can be enclosed within on the handle 2 is formed.
This device is when taking out the tapering bearing pin, should check earlier whether tapering bearing pin top has a hole, if any suitable silk hole (the same) with the screw thread on all threaded screw mandrel in two ends, screw mandrel 3 one ends are screwed into, then the handle 2 that is with beating device 1 screw mandrel 3 other ends of screwing on, whether firmly to check to impact (necessarily being screwed into enough degree of depth) several times with 1 pair of handle 2 top of beating device, the tapering bearing pin is just taken out smoothly, can carry out service work then.A tapering bearing pin upper end as a nothing silk hole then need carry out carrying out behind the drilling and tapping.
The position of considering some tapering bearing pins is special, can use the size of lengthening screw mandrel or change handle according to actual conditions instead.
