Description

A kind of triangle automatic fixture

Technical field

The utility model relates to a kind of triangle automatic fixture, belongs to the flanged technical field of burning jar of lifting.

Background technology

At present, in the electrode production process flow process, after the burning jar that needs to be equipped with electrode lifts on the kiln car, transport to again and carry out roasting in the calcining kiln, maybe will burn a jar operation that hangs kiln car and all need adopt suspender; Usually, the burning jar of several kinds of different sizes can be arranged all in each roasting process, and need to burn jar and closely be emitted on the kiln car; To improve the calcining kiln service efficiency, existing suspender all adopts four eave tiles, and is the criss-cross layout; Utilize 2 groups of symmetrical eave tiles to come the clamping object, when this suspender clamping or put was burnt jar, requisite space was bigger; With the service efficiency that reduces calcining kiln, and increased the use of material, so prior art and imperfection.

Summary of the invention

The purpose of the utility model is: provide a kind of simple in structure; When safe and reliable, novel in design, its clamping or put is burnt jar; The convenient and swift a kind of triangle automatic fixture that can saving in material of the less and clamping of taking up room is to overcome the deficiency of prior art.

The utility model is to be constructed as follows: a kind of triangle automatic fixture; Comprise suspension ring, suspension ring link to each other with the ear seat through bolt, and the ear seat is connected with automatic hitch through bolt; The ear seat is connected with suspension hook one end through jointed shaft; The other end of suspension hook is connected with guide frame through jointed shaft, and guide frame is provided with support, the automatic hitch top be provided with can with the normal pin gib head of hook mutually of groove on the support.

On the ear seat, be connected with three suspension hooks, three suspension hooks are mutually 120 ° of layouts.

Guide frame is provided with the long slot bore of the jointed shaft of can pegging graft.

In the support groove, be provided with the touch panel that can make normal pin gib head half-twist.

Owing to adopted technique scheme, during the utility model work, at first in advance the normal pin gib head on the automatic hitch hooked the groove of support; Suspension hook is opened to maximum position, through overhead traveling crane the triangle automatic fixture is imported then and burns a jar flange end, after guide frame contacts with the burning pot process is blue; The normal pin gib head contacts with the touch panel of support; Normal pin gib head half-twist along with the triangle automatic fixture is sling by overhead traveling crane, makes the normal pin gib head break away from the groove on the support; Three suspension hook gib heads hook and burn the blue lower surface of pot process, will burn the pot process orchid at last and sling; After the burning jar is hung the desired location, by gravity, the normal pin gib head of automatic hitch imports the groove of support; When with after touch panel contacts; The normal pin gib head revolves the groove that turn 90 degrees and hook support, afterwards, and overhead traveling crane lifting triangle automatic fixture upward movement; Triangle automatic fixture and burning jar are separated, finish the work; Owing to adopted technique scheme; The utility model compared with prior art, that the utility model not only has is simple in structure, make the advantage novel, that cost of manufacture is low, but also has safe and reliable; When its clamping or put is burnt jar, advantage such as take up room and clamping is convenient and swift less.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.

The enforcement of the utility model: a kind of triangle automatic fixture shown in Fig. 1～2, comprises suspension ring 1; Suspension ring 1 link to each other with ear seat 2 through bolt; Ear seat 2 is connected with automatic hitch 7 through bolt, and ear seat 2 is connected with suspension hook 4 one ends through jointed shaft 3.1, and the other end of suspension hook 4 is connected with guide frame 5 through jointed shaft 3.2; Guide frame 5 is provided with support 6, automatic hitch 7 tops be provided with can with the normal pin gib head 9 of hook mutually of groove 8 on the support 6.

On ear seat 2, be connected with three suspension hooks 4, three suspension hooks 4 are mutually 120 ° of layouts.

Guide frame 5 is provided with the long slot bore 10 of the jointed shaft 3.2 of can pegging graft.

In support 6 grooves 8, be provided with the touch panel 11 that can make normal pin gib head 9 half-twists.

A kind of method of clamping workpiece; When adopting anchor clamps to come the clamping workpiece, the bite of its anchor clamps is made as three bites, with these three bites by same intervals equably distributed and arranged on the circumference on the same plane; And the anchor clamps that adopt three suspension hooks come the clamping workpiece; Make anchor clamps when the clamping workpiece, the action direction of the Clamping force of the bite of its three suspension hooks all passes through the center of circle of same circle, can steadily piece-holder be lived like this.

In the utility model, employed anchor clamps all are to adopt the steel of high strength and high hardness to be made, and can prevent in the process of carrying, safety misadventure to occur, the workman's of assurance safety.

During the utility model work, at first the hook of the normal pin on the automatic hitch 79 is hooked the groove 8 of support 6, at this moment, the gib head of suspension hook 4 partially opens maximum position, and the triangle automatic fixture is in locking state; Hook the suspension ring 1 of triangle automatic fixture with the overhead traveling crane suspension hook; The triangle automatic fixture is imported a burning jar flange end; After burning the blue end face of pot process and the lower plane of triangle automatic fixture guide frame 5 contacts, suspension ring 1 and suspension hook 4 and automatic hitch 7 continue to move downward under the deadweight effect; After the touch panel 11 in the groove 8 of the normal pin of automatic hitch 7 hook 9 and support 6 contacts, make normal pin link up with 9 and revolve and turn 90 degrees; Afterwards, the triangle automatic fixture is upward movement under the lifting of overhead traveling crane, and ear seat 2 drives automatic hitch 7 and suspension hook 4 upward movements; Make normal pin hook 9 throw off the groove 8 of support 6, simultaneously, the long slot bore 10 of three suspension hooks guide frame 5 in the restriction lower edge of jointed shaft 3.2 upwards slides and rotates; Partly hook until, suspension hook 4 gib heads and to burn the blue lower surface of pot process, the same day, hitch was lived suspender when continuing up to move; Can will burn jar sling, promptly overhead traveling crane can sling whole suspender with burn jar also upward movement together.

After the burning jar was hung the desired location, overhead traveling crane drove the triangle automatic fixture and moves downward by gravity; Ear seat 2 promote three suspension hooks 4 drive jointed shafts 3.2 along the long slot bore 10 of guide frame 5 to lower slider and rotate, the normal pin hook 9 of automatic hitch 7 imports the groove 8 of supports 6, after the touch panel 10 in the groove 8 of normal pin hook and support 6 contacts; Normal pin hook 9 revolves and turn 90 degrees; Normal pin hook 7 hooks the groove of support, and afterwards, the triangle automatic fixture is upward movement under the effect of overhead traveling crane; Be that overhead traveling crane can separate suspender and burning jar, accomplish the work of lifting.

The guide piece that the utility model is provided with can be exactly with burning in jar importing triangle automatic fixture; Three guide frames 5 are mutually 120 ° of layouts; When its clamping or put is burnt jar; And the action direction of the Clamping force of the bite of three suspension hooks all passes through the center of circle of same circle, according to 3 principles of confirming a plane, during the clamping object; Not only stable but also take up room lessly, also saved material.
