The stepping type mechanical hand comprises a pair of stepping beams arranged in the X direction and two sets of clamping jaws arranged in the Y direction, and the two sets of clamping jaws are connected to the two stepping beams respectively, are symmetrically arranged, and correspond in a one-to-one manner; the clamping jaws are connected to the stepping beams through connecting components; and the connecting components comprise clamping jaw seats, trigger rods and detection switches; the trigger rods are arranged in the stepping beams in a penetrating manner in the Y direction, and the clamping jaws are fixedly connected to one ends of the trigger rods through the clamping jaw seats; and the detection switches are located at the other ends of the trigger rods and fixedly connected to the stepping beams. The stepping type mechanical hand is exquisite in structure, wide in application range, good in use effect, low in potential safety hazard and the like.

Description

A kind of step mechanical gearing mechanism hand

Technical field

The present invention relates to step rate feeding field, particularly relate to the improvement that step mechanical gearing mechanism hand (fixture) is proposed.

Background technology

At present, for enhancing productivity, the automation multistation forging and stamping mode of production adopting step mechanical gearing mechanism hand (also known as step rate manipulator) to carry out feeding is widely used.Wherein, representative as State Bureau be called " the forging industry multistation stepped feeding method based on articulated robot " in the portion that on February 1st, 2012 announces, application number is the document of " 201110301016.8 ", be equipped with one to one " two groups of jaws " on two " motion beams " in this case, to realize the conveying of forging between multiple station.

But, preset because the specification of jaw in each station is generally, therefore, once there is machining deviation in reality processing, then will cause effectively cannot clamping, taking out; If now manipulator works on, then the workpiece gone up in a station will directly be extruded, and by the impact of its high temperature high weight, very easily will cause damage to whole hot forging equipment, and bring great potential safety hazard.

Summary of the invention

The present invention is directed to above problem, provide that a kind of structure is simple, method of operating is simple, applied widely, effectively can avoid the step mechanical gearing mechanism hand occurring not clamping phenomenon.

Technical scheme of the present invention is: comprise a pair along X to the step rate arranged and two groups of jaws arranged along Y-direction, jaw described in two groups is connected on two step rates, described in two groups, jaw is symmetrical arranged and one_to_one corresponding, described jaw is connected on step rate by coupling assembling, and described coupling assembling comprises jaw seat, frizzen and sense switch;

Described frizzen is located in described step rate along Y-direction, and described jaw is fixedly connected on one end of frizzen by jaw seat, and described sense switch is positioned at the other end of described frizzen and is fixedly connected on step rate.

Described coupling assembling also comprises at least one axis of guide arranged along Y-direction, and the described axis of guide is located in described step rate, and one end of the described axis of guide to be fixedly connected on jaw seat and to be provided with Flat wire spring between the other end of the axis of guide and described step rate.

Linear bearing is socketed with outside the described axis of guide.

Described jaw seat offers at least one strip through hole, and described strip through hole arranges along Y-direction and is provided with the dog screw be fixedly connected on jaw in described strip through hole.

The present invention has set up the coupling assembling be made up of frizzen and sense switch etc. between jaw and step rate, it is made to add man-hour, once occur that the phenomenon of " folder is empty " can be reported to the police, thus effectively avoid the problem of whole the hot forging equipment damage caused because of " folder is empty ".It has delicate structure, applied widely, result of use good and the feature that potential safety hazard is low.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention,

Fig. 2 is the left view of Fig. 1,

Fig. 3 is the top view of Fig. 1,

Fig. 4 is the A place partial enlarged drawing of Fig. 3;

In figure, 1 is step rate, and 2 is jaws, and 3 is coupling assemblings, and 31 is jaw seats, and 311 is strip through holes, and 312 is dog screws, and 32 is frizzens, and 33 is sense switches, and 34 is axis of guides, and 35 is Flat wire springs, and 36 is linear bearings.

Detailed description of the invention

The present invention as Figure 1-4, comprise a pair along X to the step rate 1 arranged and two groups of jaws 2 arranged along Y-direction, jaw 2 described in two groups is connected on two step rates 1, described in two groups, jaw 2 is symmetrical arranged and one_to_one corresponding, described jaw 2 is connected on step rate 1 by coupling assembling 3, and described coupling assembling 3 comprises jaw seat 31, frizzen 32 and sense switch 33;

Described frizzen 32 is located in described step rate 1 along Y-direction, and described jaw 2 is fixedly connected on one end of frizzen 32 by jaw seat 31, and described sense switch 33 is positioned at the other end of described frizzen 32 and is fixedly connected on step rate 1.During use, if frizzen contact (propping up) sense switch, then sense switch does not send signal; Otherwise then send alarm signal (display lamp constantly glimmers), alert does not clip to workpiece.

Its operation principle is: when bar sends into lathe first station after punching press by material guide device, two step rates carry out Y-direction motion toward lathe center simultaneously, until clip to workpiece, if the jaw folder of each station is less than workpiece, the sense switch of jaw afterbody can send signal warning, be shown as and do not clip to workpiece, lathe and manipulator can quit work; If the sense switch of jaw does not give a warning, then step rate along Z-direction lifting, can make the upper plane exceeding bed die bottom of workpiece; Then move in the direction that step rate yearns for next station along X, workpiece is delivered to next station; Then step rate moves downward along Z-direction, ensures that workpiece can fall in the mould of station accurately, and then two step rates open along Y-direction to both sides simultaneously, ensures the normal work not affecting lathe; Finally, step rate in the contrary X of feed direction to motion, a station before moving to; Complete.

Because the coupling assembling be made up of frizzen and sense switch etc. has been set up in this case between jaw and step rate, it is made to add man-hour, once occur that the phenomenon of " folder is empty " can be reported to the police, thus effectively avoid the problem of whole the hot forging equipment damage caused because of " folder is empty ".It has delicate structure, applied widely, result of use good and the feature that potential safety hazard is low.

Described coupling assembling 3 also comprises at least one axis of guide 34 arranged along Y-direction, the described axis of guide 34 is located in described step rate 1, and one end of the described axis of guide 34 to be fixedly connected on jaw seat 31 and to be provided with Flat wire spring 35 between the other end of the axis of guide 34 and described step rate 1.Play the guiding role by the motion of the axis of guide to jaw seat, by Flat wire spring, jaw seat is played reset role.

Linear bearing 36 is socketed with outside the described axis of guide 34.

Described jaw seat 31 offers at least one strip through hole 311, and described strip through hole 311 arranges along Y-direction and is provided with the dog screw 312 be fixedly connected on jaw 2 in described strip through hole 311.Make the Y-direction position of jaw adjustable, like this, as there is above-mentioned " folder is empty " problem, then the Y-direction position by adjusting the jaw of corresponding station solves.
