Description
Technical field
This application involves technical field of mechanical processing, specifically a kind of pin removal for T-type pin.
Background technique
T-type pin is mainly used for the structure connection of metal material tooling, and such pin is usually used in fixing tool wheel, tooling
The connection between toolings attachment and tooling main body such as gantry type frame, tooling block.Since tooling main body is when in use for attached
The position accuracy demand of part is very high, it is therefore desirable to is located by connecting using pin.For common T-type pin, when in use
Firstly the need of holding cross bar, then pin is firmly extracted into location hole.But due to the connection between tooling attachment and tooling main body
It is influenced by gravity factor, often has very big frictional force, pin is caused not to be drawn out easily, if pulled out by force using percussion mode
Out, it be easy to cause injury to personnel or pin to destroy, to form security risk.
Existing patent application such as Patent No. CN201520688923.0, the applying date 20150908, a kind of entitled T shape
The utility model patent of pin pin removal, technical solution are as follows: the utility model discloses a kind of T shape pin pin removals, it is wrapped
Bolt (2), sliding hammer (4), nylon jacket (5) and pin pulling head (6) are included, bolt (2) is made of bolt head (1) and screw rod (3), bolt
Head (1) and screw rod (3) are integrally formed, and are provided with internal screw thread (9) on pin pulling head (6), and bolt (2) and pin pulling head (6) pass through spiral shell
Line connects, and the side on screw rod (3) close to pin pulling head (6) is fixedly installed with nylon jacket (5) by interference fit, nylon jacket (5)
It is provided between bolt head (1) sliding hammer (4), first baffle (8) and second baffle (7) is additionally provided on pin pulling head (6), the
The shape of one baffle (8) is U-shaped.
The pin removal head of above-mentioned patent is only applicable to round pin, can not be suitable for existing frequently-used T-type pin.
Summary of the invention
Existing T-type pin is not drawn out easily, there are security risks in order to solve the problems, such as to exist in the prior art, currently proposed
It is a kind of that convenient for fixed T-type pin, energy is mechanical firmly for the pin removal of T-type pin again.
A kind of pin removal for T-type pin, it is characterised in that: described including dead man, sliding sleeve, nylon jacket and pin pulling head
Having on dead man can be along the sliding sleeve that dead man slides above and below, and the dead man bottom is disposed with nylon jacket and pin pulling head, described to pull pin
Head includes attachment base, is provided with hook on the attachment base, there is arc-shaped structure, and the hook inside the hook bottom of the hook
Free end be crotch structure.
The hook bottom top of the hook is inclined to set for surface interconnecting piece.
The quantity of the hook is two, and two hook structures are identical and are arranged side by side, and there are gaps between two hooks.
The attachment base bottom of the pin pulling head is provided with screw thread, and the pin pulling head is connected by screw thread with the bottom of dead man.
The nylon jacket is fixed on dead man bottom end.
The application is connect using the crotch structure on pin pulling head with the cross bar of T-type pin, pin pulling head crotch inner diameter size with
Spacing can be adjusted according to T-type pin size.Recycling slides over when fast moving on dead man, to shape for hat knot at the top of sliding sleeve
The impact force of structure extracts T-type pin.
The advantages of the application, is:
The application uses hand after pin pulling head is connect with T-type pin with following good effect compared to existing mode of pulling pin
Sliding sleeve part is held, then firmly quickly impact upwards, is extracted pin using the instantaneous impact between sliding sleeve and dead man.It keeps away
Bring firmly insufficient problem of directly being pulled pin with hand is exempted from, while hand being avoided to be hurt.Impact is in Buddhist nun when sliding sleeve is sprung back downwards
On the actor playing a supporting role, avoid damaging pin pulling head.
Detailed description of the invention

Specific embodiment
In order to further illustrate rather than limit the application above-mentioned implementation, in the following with reference to the drawings and specific embodiments
The application is described further, but therefore the application is not limited among the practical range.All these designs
It should be regarded as the protection scope of content and the application disclosed in the present application.
Embodiment 1
A kind of pin removal for T-type pin 5, including dead man 1, sliding sleeve 2, nylon jacket 3 and pin pulling head 4, on the dead man 1
Having can be along the sliding sleeve 2 that dead man 1 slides above and below, and 1 bottom of dead man is disposed with nylon jacket 3 and pin pulling head 4, described to pull pin
