Abstract

The utility model relates to an unhooking device for falling work piece, which comprises two vertically fixed guide column, a fixed panel sliding up and down along the two guide columns and a pothook that revolves at the center and is fixed at the bottom of the fixed panel; wherein the center of the hook is fixed by a moveable peg between two juxtaposed fixation blocks at the bottom to the fixed panel; the pothook is formed by a hook and a hook stem and takes the L shape; a tightening spring is arranged between the hook stem and the fixed panel, corresponding to the end of the hook stem; the fixed panel fixes an electromagnet that can stick out a contactor downward, the contactor can press the end of the hook stem when sticking out so as to make the hook slant downward and enable the work piece on the hook automatically fall; when the contactor contracts, the end of the hook stem stops at the contactor and at the same time the hook is in the vertical status and is easily to hook up the work piece. The utility model provides an unhooking device for falling work piece that can be operated conveniently and save the accessory.

Description

Workpiece falling bodies trip mechanism

Technical field

The utility model belongs to workpiece falling bodies punch test device, the workpiece drop test device that particularly a kind of workpiece is automatically-unhooked.

Background technology

In the prior art, carry out often running into workpiece in the workpiece drop test process and how to break off relations, can adopt oil pressure, cylinder or mechanical system that hook and workpiece are thrown off usually, this way needs many annexes, as oil hydraulic system, pneumatic supply and other mechanisms, manufacturing cost height.

Summary of the invention

In order to remedy above deficiency, the utility model provides a kind of not only easy to operate but also saves the workpiece falling bodies trip mechanism of annex.

The technical solution of the utility model is achieved in that a kind of workpiece falling bodies trip mechanism, the guide pillar that comprises two vertical fixing, the fixed head that slides up and down along this two guide pillar, the middle part rotational fixation is formed in the hook of this fixed head bottom, this hook is made up of the hook and the neck of hook and is the L type, and be provided with back-moving spring between this neck of hook and this fixed head, to should neck of hook end, this fixed head is fixed an electromagnet that can stretch out contact downwards, when stretching out, this contact can push down this neck of hook end downwards, make this hook downward-sloping, be convenient to the automatic falling bodies of workpiece on this hook, and this contact when shrinking this neck of hook end stop bit this hook in the time of this contact be convenient to hook workpiece in vertical state.

As further improvement of the utility model, this hook middle part is fixed between these two fixed blocks that are arranged side by side in fixed head bottom by movable pin.

As further improvement of the utility model, these fixed head two ends are recess, and are limited between this two guide pillar, are convenient to this fixed head and slide up and down along this two guide pillar, and this fixed head also can be set between this two guide pillar in activity.

As further improvement of the utility model, activity wears a guiding block between this two guide pillar of this hook bottom, this guiding block that should link up with is fastened a guide rod that can hook this hook, this guide rod top wears the counterweight that is used for the workpiece drop test, and bottom fixation workpiece drop test mould, this fixed head top is provided with frame, and fixing electric block, and this electric block can should hook and the guiding block that should link up with by the retainer plate pull-up on this fixed head.

Useful technique effect of the present utility model:

This fixed head bottom is fixed in based on movable pin in this hook middle part, when the electromagnet contact is made contractive action, back-moving spring between this hook and this fixed head upwards draws this neck of hook, cause this neck of hook end stop bit when this electromagnet contact, to become horizontal direction, the hook of this hook is in plumbness, slides up and down along this two guide pillar thereby hook workpiece;

When the electromagnet contact was done to stretch out action, this contact was pushed down the neck of hook of this hook, makes the hook of this hook downward-sloping, thus the automatic landing of workpiece on the hook.

Fig. 2 is in the structural representation of the state of hooking for the utility model;

Fig. 3 is in the structural representation of unhook state for the utility model.

Embodiment

In conjunction with Fig. 1, Fig. 2 be further described below Fig. 3:

A kind of workpiece falling bodies trip mechanism, the

guide pillar

11 and 12 that comprises two vertical fixing, the fixed head 2 that slides up and down along this two guide pillar, the middle part rotational fixation is formed in the hook 3 of this fixed head bottom, this hook middle part is fixed between these two fixed blocks that are arranged side by side 21 in fixed head bottom by movable pin, these fixed head two ends are recess, and be limited between this two guide pillar, being convenient to this fixed head slides up and down along this two guide pillar, this hook 3 is made up of the hook 31 and the neck of hook 32 and is the L type, and be provided with back-moving spring 4 between this neck of hook 32 and this fixed head 2, to should neck of hook end, this fixed head be fixed an electromagnet 5 that can stretch out contact 51 downwards.Electromagnet described in the utility model is a kind of device that utilizes electromagnetic attraction manipulation, hitching machinery, to finish the expection action, the sticking that also is used for steel-iron components is fixed, lifting carrying etc., and electromagnet is made up of fixed core that field copper is housed and movably moving institute unshakable in one's determination.Described electromagnet is installed on described fixed head 2 bottoms, can push down this neck of hook 32 ends downwards when this contact 51 stretches out when energising, make this hook 31 downward-sloping, be convenient to the automatic falling bodies of workpiece on this hook, and when dead electricity and this contact 51 when shrinking these neck of hook 32 end stop bits this hook 31 in the time of this contact 51 be convenient to hook workpiece in vertical state.

Activity wears a guiding block 7 between this two guide pillar of this hook bottom, this guiding block that should link up with is fastened a guide rod 8 that can hook this hook, this guide rod top wears the counterweight 9 that is used for the workpiece drop test, and bottom fixation workpiece drop test mould, this fixed head top is provided with frame 6, and fixing electric block 61, this electric block can by the retainer plate pull-up on this fixed head should hook and should hook on guiding block 7.
