Abstract
The utility model discloses a kind of pin pulling attachments, including slide bar, sleeve and clamping head, sleeve is slideably socketed on slide bar, clamping head is connect with slide bar one end, the slide bar other end is fixed with handle, and block plate is equipped between handle and slide bar, and the clamping head includes slide bar linkage section and pin linkage section, the pin linkage section axis of clamping head is chosen hole equipped with pin, and the pin linkage section of clamping head is radially equipped with chooses multiple threaded fastening holes that hole connects with pin.The utility model passes through rapidly moving upward sleeve, it is made to generate larger impact force between block plate so as to extract pin, in this way can be reliable and stable, quick fast and pin be nondestructively extracted, the pin for being applicable to the higher multiple types part of surface requirements is chosen.
Description
Technical field
The utility model is related to airline carriers of passengers auxiliary power unit maintenance technique fields, and in particular to a kind of pin is chosen dress
It puts.
Background technology
On large and medium-sized aircraft and big payload helicopter, in order to reduce the dependence to ground (airport) power supply unit, it is equipped with
Independent miniature power unit, referred to as auxiliary power unit.Auxiliary power unit includes loading calm the anger diffuser and power
It calms the anger the parts such as diffuser, is usually mounted with multiple for positioning the pins of Assembly part on such part, and pin is usually adopted
With the mode of interference fit, general tool is difficult to be pulled out, and is easily damaged piece surface after extracting, and leads to maintenance cost
Increase.
Invention content
The purpose of this utility model is to provide a kind of reliable and stable, rapid easily pin pulling attachments.
The purpose of this utility model is achieved through the following technical solutions：A kind of pin pulling attachment, including slide bar, set
Cylinder and clamping head, sleeve are slideably socketed on slide bar, and clamping head is connect with slide bar one end, and the slide bar other end is fixed with
Handle, is equipped with block plate between handle and slide bar, the clamping head includes slide bar linkage section and pin linkage section, the pin of clamping head
Linkage section axis is chosen hole equipped with pin, the pin linkage section of clamping head be radially equipped with pin choose hole connect it is multiple
Threaded fastening hole.
Further, the shape of described sleeve one end and the shape of block plate match.
Further, the pin chooses hole as blind hole.
Further, the clamping head passes through thread fitting with slide bar.
The utility model makes it generate larger impact force between block plate so as to extract by rapidly moving upward sleeve
Pin, in this way can be reliable and stable, quick fast and nondestructively extracts pin, and it is higher to be applicable to surface requirements
The pin of multiple types part is chosen.

Specific embodiment
As shown in FIG. 1 to 3, pin pulling attachment provided in this embodiment includes slide bar 1, sleeve 2 and clamping head 3, set
Cylinder 2 is slideably socketed on slide bar 1, and clamping head 3 and the threaded one end of slide bar 1 coordinate, and the other end of slide bar 1 is fixed with handle
4, block plate 6 is equipped between handle 4 and slide bar 1, the shape and the shape of block plate 6 of described 2 one end of sleeve match.The clamping head
3 include slide bar linkage section and pin linkage section, and the axial direction of the pin linkage section of clamping head 3 is chosen hole 7 equipped with pin, and is pressed from both sides
It holds radially being equipped with for first 3 pin linkage section to choose multiple threaded fastening holes 8 that hole 7 connects with pin, the pin is chosen
Hole 7 is blind hole.
The course of work of the utility model is：Clamping head 3 is connect, and passed through using bolt with the pin 5 for needing to extract
Threaded fastening hole 8 fixes pin 5, and holding sleeve 2 makes it rapidly moving upward from 1 bottom of slide bar, 2 top of sleeve and block plate 6
The enormous impact force generated after shock can be such that pin 5 smoothly extracts, and entirely the process of choosing needs that slide bar 1 is made to keep same with pin 5
Spindle Status.
The above is only the utility model preferred embodiment, but the scope of protection of the utility model is not limited to
This, any transformation carried out based on technical solution provided by the utility model and inventive concept and replacement should all be covered in this reality
With in novel protection domain.
