Abstract
The utility model discloses a stair-type spring pin punch which is composed of a guide head, a first level punch rod, a second level punch rod, a handle and a rubber sleeve which are integral with the stair-type spring pin punch. The guide head, the first level punch rod, the second level punch rod and the handle are sequentially in a stair shape. The guide head on the end of the stair-type spring pin punch is inserted into a hollow core of an inner spring pin, and the guide head plays a guiding role when the inner spring pin is punched. Then the first level punch rod of the stair-type spring pin punch is used to enable the inner spring pin to be punched out. After the inner spring pin which is sleeved inside a hollow core of an outer spring pin is punched out, the stair-type spring pin punch can continue to punch out the outer spring pin. When the outer spring pin is punched, the first level punch rod enters into the hollow heart of the outer spring pin and plays a guiding role, and the outer spring pin is punched out through the second level punch rod. Therefore, by using the stair-type spring pin punch, spring pins are dismantled conveniently and efficiently, effect is good, efficiency is high, and the stair-type spring pin punch is safe and reliable.
Description
Technical field
The utility model belongs to the power generation technical field of tools, particularly a kind of notch cuttype resilient key punching pin.
Background technology
At mechanical field, the part that spring catch is widely used in being installed on the axle is located by connecting, fixes etc., and spring catch is a kind of cylindrical body of hollow without a head, and is axially grooved, and two cephalic pars have chamfering.Resilient key than being easier to, is driven into gently pin-and-hole with hand hammer and gets final product when mounted.But need punching pin during dismounting.The structure of present punching pin is isometrical column structure.With the minor diameter punching pin resilient key of minor diameter is gone out first during dismounting, and then with large diameter punching pin the major diameter resilient key is gone out.Use present punching pin inconvenient operation, speed slow, slip phenomenon very easily appears in unloading process, injure hand by a crashing object, have a lot of drawbacks.
The utility model content
The utility model provides a kind of easy to operate, safe and reliable, notch cuttype resilient key punching pin that efficient is high.
A kind of notch cuttype resilient key punching pin is that guide head, one-level jumper bar, secondary jumper bar, handle and the rubber sleeve that has one to connect consists of, and described guide head, one-level jumper bar, secondary jumper bar and handle are stepped successively.
The diameter of described guide head is less than the internal diameter of interior resilient key.
The diameter of described one-level jumper bar is less than the internal diameter of outer resilient key.
Be set with rubber sleeve on the described handle.
Terminal guide head of the present utility model inserts in resilient key hollow.The punching in resilient key the time, guide head plays guide effect.Then utilize the one-level jumper bar of notch cuttype resilient key punching pin that interior resilient key is gone out.When punching pin rushes interior resilient key like this, skidding can not appear.
After overlapping the interior resilient key in hollow of resilient key outside and being rushed out, punching pin can continue to go out outer resilient key.Punching is during outer resilient key, and the one-level jumper bar of punching pin has entered in major diameter resilient key hollow, plays guide effect, by the secondary jumper bar major diameter resilient key is gone out.So use that notch cuttype resilient key punching pin dismounting resilient key is convenient and swift, effective, efficient is high, safe and reliable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of notch cuttype resilient key punching pin is that guide head 1, one-level jumper bar 2, secondary jumper bar 3, handle 4, the rubber sleeve 5 that one is with it arranged consists of, and described guide head 1, one-level jumper bar 2, secondary jumper bar 3, handle 4 are stepped successively.The diameter of described guide head 1 is less than interior resilient key internal diameter.Described one-level jumper bar 2 is less than the internal diameter of outer resilient key.Be set with rubber sleeve 5 on the described handle 4, be used for preventing punching pin from skidding and minimizing work in the vibrations that are subject to of hand.
Utilize the utility model, in terminal guide head of the present utility model 1 is inserted in resilient key hollow.The punching in resilient key the time, guide head 1 plays guide effect.Then utilize the one-level jumper bar 2 of notch cuttype resilient key punching pin that interior resilient key is gone out.When notch cuttype resilient key punching pin rushes interior resilient key like this, skidding can not appear.
After overlapping the interior resilient key in hollow of resilient key outside and being rushed out, notch cuttype resilient key punching pin can continue to go out outer resilient key.Punching is during outer resilient key, and the one-level jumper bar 2 of punching pin has entered in outer resilient key hollow, plays guide effect, by secondary jumper bar 3 outer resilient key is gone out.So use that notch cuttype resilient key punching pin dismounting resilient key is convenient and swift, effective, efficient is high, safe and reliable.
Claims (4)
1. notch cuttype resilient key punching pin is characterized in that: be that guide head, one-level jumper bar, secondary jumper bar, handle and the rubber sleeve that has one to connect consists of, described guide head, one-level jumper bar, secondary jumper bar and handle are stepped successively.
2. a kind of notch cuttype resilient key punching pin as claimed in claim 1, it is characterized in that: the diameter of described guide head is less than the internal diameter of interior resilient key.
