Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1, Figure 2 and Figure 3, the special fixture of the transfer robot of the present embodiment.This special fixture includes main body 14, connection dish 11 and two clamping devices, and the two clamping device is installed in main body 14, and special fixture also includes four buffer units 13 and two self-reacting devices 20.
Buffer unit 13 includes first mounting seat the 131, first guide post 133, shock absorber part 135.Being fixed with a connecting plate 12 on connection dish 11, the first mounting seat 131 is machined with an installing hole, be fixed with a graphite copper sheathing 132 in this installing hole, this first mounting seat 131 is fixed on connecting plate 12 by screw.The lower end of the first guide post 133 is fixed with a mounting blocks 136, and this mounting blocks 136 is fixed in main body 14, thus is fixed in main body 14 by the first guide post 133.First guide post 133 is set in the graphite copper sheathing 132 of the first mounting seat 131, and through the first mounting seat 131, graphite copper sheathing 132 can move along the first guide post 133, and the i.e. first mounting seat 131 can move along the first guide post 133.The end stretching out the first mounting seat 131 on first guide post 133 has been screwed the first block 134.Shock absorber part 135 is set on the first guide post 133 at main body 14.Decision design, shock absorber part 135 is vibration-reducing rubber block.
Self-reacting device 20 includes second mounting seat the 204, second guide post 202, spring 203 and transverse slat 201.Being machined with installing hole in second mounting seat 204, this second mounting seat 204 is fixed in main body 14 by screw.One end of second guide post 202 is connected with transverse slat 201, and the other end of the second guide post 202 is set in the installing hole of the second mounting seat 204, and the second guide post 202 is through the second mounting seat 204, and the second mounting seat 204 can move along the second guide post 202.The end stretching out the second mounting seat 204 on second guide post 202 has been screwed the second block 205.Spring 203 is set on the second guide post 202.
Preferred design, clamping device includes driving cylinder 17, clamp arm 16, clamping plate 12 and support bar 18.Driving cylinder body and main body 14 chain connection of cylinder 17, one end of clamp arm 16 and the piston rod chain connection driving cylinder 17, clamping plate 12 is fixed on the other end of clamp arm 16 by screw.Support bar 18 is fixed in main body 14, and the center of clamp arm 16 is fixed with a connecting rod 19, this connecting rod 19 and support bar 18 chain connection, so that clamp arm 16 and support bar 18 carry out chain connection.In palletization, cylinder 17 is driven to drive clamping plate 12 to carry out opening action or pinching action, to realize unclamping alloy pig or clamping alloy pig.
Below the operation principle of the special fixture of transfer robot of the present utility model is described in further detail.
Connection dish 11 is connected with the mechanical arm (accompanying drawing is not shown) of transfer robot, drives cylinder 17 to drive two clamping plates 12 to open.During piling, transfer robot drives special fixture to move and be positioned at the surface of alloy pig, then special fixture is driven to decline, during decline, transverse slat 201 contacts with the end face of alloy pig, then to transverse slat one pressure of applying, compression spring 203 makes the second guide post 202 move along the installing hole of the second mounting seat 204 to alloy pig, so that special fixture is adaptive to the skimble-scamble alloy pig of height dimension.Special fixture declines the rear drive cylinder 17 that puts in place and drives two clamping plates 12 to clamp alloy pig, then transfer robot drives special fixture to rise, and move to setting position, then special fixture is driven to decline and put down alloy pig, it is provided with buffer unit due to connection dish 11 and main body 14 during putting down, therefore can buffer the alloy pig put down and the shock of lower floor's alloy pig, thus prevent special fixture and damage because of clashing into.Last special fixture decline puts in place, drives cylinder 17 to drive two clamping plates 12 to open and unclamp alloy pig.
To sum up, the special fixture of transfer robot of the present utility model is provided with buffer unit and self-reacting device, adapts to the skimble-scamble alloy pig of height dimension, preferably clamps alloy pig, to reduce the probability of ingot, it is ensured that the safety of production;There is situation about clashing in its buffer unit when being avoided that piling, thus prevents special fixture from damaging, and decreases maintenance cost.Further, its clamping plate is detachably replaced, and therefore versatility is higher, can be suitably used for the alloy pig of different demoulding degree;Overall structure is the compactest, it is adaptable to most alloy pig code ingot machine;Use modularized design, be convenient for changing parts;Using graphite copper sheathing and the first guide rod to coordinate, ruggedness is more preferable, extends the service life of part;The scope being suitable for is also wide, extensively can apply at field of industrial production.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
