Abstract

The utility model discloses an axial withdrawal tool of a hinge pin, and the tool is characterized in that a stepped hole is formed in the center of a pull-out screw; the pull-out screw is locked on the section of the hinge pin by penetrating an inner hexagon screw which is matched with a threaded hole of the hinge pin through the stepped hole; the pull-out screw is connected with the hinge pin into a whole; an outer ring of the pull-out screw is sleeved into a crossing frame; two pressing pins of the crossing frame press on solids on the two sides of the hinge pin to form a supporting point of a pull force; a bearing is sleeved on the outer ring of the pull-out screw; the lower end face of the bearing presses on the upper flat surface of the crossing frame; a nut is screwed in from the top end of the pull-out screw and presses on the upper end face of the thrust ball bearing; and a pulling force is provided for the hinge pin through rightwards screwing the nut. The axial withdrawal tool can be widely applied to the detachment operation of hinge pins with threaded holes in the end faces, the operation is simple and convenient, the labor is saved, the hinge pin can be rapidly pulled out in the axial direction, and the aim of detachment is achieved.

Description

A kind of axial extracting tool of bearing pin
Technical field
The utility model relates to a kind of axial extracting tool of bearing pin, especially relates to a kind of simple to operationly, laborsaving, can fast bearing pin axially be pulled out, and reaches the extracting tool of the purpose of dismounting.
Background technology
Now the axial extracting tool of the bearing pin that uses is that a nut that is complementary by a screw rod that is complementary with the pin roll end face screw, and screw rod, center are drilled with the size mechanism that steel plate that the thickness of through hole conforms to width, annular bloom that a tile height conforms to centre bore constitute that conforms to.Earlier screw rod is spun on the end face screw of bearing pin when installing and using, puts the steel plate that annular bloom and center are drilled with through hole again, at the other end precession nut of screw rod, by screwing nut at steel plate bearing pin is pulled out then.
The shortcoming of this structure is: because screw rod is meticulous, so when screwing nut, screw rod is easy to just cause distortion and sliding tooth under the effect of shearing force and torsion, finally cause losing efficacy.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of can prevent screw rod distortion and sliding tooth, and the axial extracting tool of a kind of bearing pin simple to operation, laborsaving and that fast bearing pin is axially pulled out.
It is such that structure of the present utility model constitutes, a kind of axial extracting tool of bearing pin, its feature has the center stepped hole that soket head cap screw (5) is installed pulling out screw rod (1), soket head cap screw (5) is tightened on the bearing pin termination, pull out screw rod (1) middle part external diameter and stride frame (4), striding frame (4) outer end is bearing (3), and bearing (3) outer end is nut (2), and nut (2) is spun on pulls out screw rod (1) outer end.
The center stepped hole of pulling out screw rod (1) is locked on the section of bearing pin by putting on a soket head cap screw that is complementary with the bearing pin screw thread (5), makes to pull out screw rod (1) and be connected with bearing pin.
The cylindrical of pulling out screw rod (1) packs into strides frame (4), two presser feets of striding frame (4) are pressed on the entity of bearing pin both sides, bearing (3) is enclosed within on the outer ring of pulling out screw rod (1), the lower surface is pressed in the upper surface of striding frame (4), the upper surface is pressed on nut (2) inner face, nut (2) is pressed in the upper surface of bearing (3) from pulling out the top precession of screw rod (1).
The utility model has the advantages that: be widely used in the dismounting that end face has the bearing pin of screw, simple to operation, by bearing pin minor thread originally is transformed into the suitable screw thread of size, thereby reach laborsaving, fast and effectively bearing pin is axially pulled out, reach the purpose of dismounting, for maintenance of equipment has reduced the time, improve production efficiency, increased the benefit of enterprise.
Description of drawings
Fig. 1 is the utility model front view.
Among the figure, pull out screw rod (1), nut (2), bearing (3), stride frame (4), soket head cap screw (5).
The specific embodiment
Further specify parts and the structure of the extracting tool of the utility model bearing pin below in conjunction with accompanying drawing.
As shown in drawings, the extracting tool of the utility model bearing pin, there is a stepped hole at the center of pulling out screw rod (1), is locked on the section of bearing pin by putting on a soket head cap screw that is complementary with the bearing pin screwed hole (5), makes to pull out screw rod (1) and be connected with bearing pin; The center of striding frame (4) upper head plate has through hole, and the outer ring of pulling out screw rod (1) packs into the through hole of striding frame (4), and two presser feets of striding frame (4) are pressed on the entity of bearing pin both sides, forms the strong point of pulling force; Bearing (3) is enclosed within on the outer ring of pulling out screw rod (1), and the lower surface is pressed in the last plane of striding frame (4), can play the effect of the power of reducing friction; Nut (2) is pressed in the upper surface of bearing (3) from pulling out the top precession of screw rod (1), just can provide pulling force to bearing pin behind the right-handed nut.
The utility model as long as will pull out screw rod (1) with soket head cap screw (5) is connected with bearing pin, just can provides pulling force to bearing pin behind the right-handed nut (2) again, thereby bearing pin is pulled out in use.

Claims (3)

1. the axial extracting tool of a bearing pin, its feature has the center stepped hole that soket head cap screw (5) is installed pulling out screw rod (1), soket head cap screw (5) is tightened on the bearing pin termination, pull out screw rod (1) middle part external diameter and stride frame (4), striding frame (4) outer end is bearing (3), bearing (3) outer end is nut (2), and nut (2) is spun on pulls out screw rod (1) outer end.
2. according to the axial extracting tool of the described a kind of bearing pin of claim 1, it is characterized in that the center stepped hole of pulling out screw rod (1) is locked on the section of bearing pin by putting on a soket head cap screw that is complementary with the bearing pin screw thread (5), make and pull out screw rod (1) and be connected with bearing pin.
