Description

Work holder and workpiece transporting clamp

Technical field

The present invention relates to flank, the workpiece transporting clamp of carrying this workpiece and the work holder that workpiece is fixed thereon that clamping is formed on the back of work side.

Background technology

Hydraulic-transfer is by workpiece is immersed in the water surface of floating the water-soluble film that is formed with printed patterns, this printed patterns is transferred to the surface decoration technique of surface of the work, on resin, form wood grain, leather, the first-class pattern of natural stone, pay senior sensation.

In this case, workpiece is carried the one side submergence by conveyer that moves or the robot that moves arm with the track of stipulating by one side on the hydraulic-transfer groove.But,, therefore be fixed on the transporting clamp, utilize conveyer or robot simultaneously to carry these anchor clamps simultaneously to carry out hydraulic-transfer owing to workpiece directly not being fixed on conveyer or being fixed on the robot arm.

On resin, owing to form flank in the rear side that is not forming decoration in processing and forming, therefore, transporting clamp is the position that makes the corresponding flank of clip of this flank of clamping, be provided with the interval of regulation and form.

And, after the workpiece that operating personnel will be transported to the hydraulic-transfer groove is installed on the transporting clamp that hydraulic-transfer uses, in fact operating personnel unload workpiece from transporting clamp again, this transporting clamp is installed in conveyer or the robot in the installation site, is unloaded from conveyer or robot at discharge location.

In this case, in order to alleviate operating personnel's burden, require to install easily workpiece, and do not allow caducous clamper in hydraulic-transfer, of paramount importance is the latter.

Fig. 3 represents existing transporting clamp 51 as above, and the work holder 53 that clamping is formed on the flank R at the workpiece W back side is installed on the pedestal 52 of the machine of being transferred or robotic delivery with the interval of stipulating.

For work holder 53, flex plate 55 one distolateral superimposed and be weldingly fixed on the rigid plate 54, this rigid plate 54 is fixed on the pedestal 52, and the elastic force clamping by flex plate 55 is inserted into workpiece W between rigid plate 54 and the flex plate 55 from its free end side 55b.

Flex plate 55 is bent to form, and partly forms the clamping part 53a of holding workpiece W with the leading section side of rigid plate 54 butts.

For workpiece W being inserted among the clamping part 53a sleekly, the front of the clamping part 53a of rigid plate 54 and flex plate 55 enlarges laterally and forms with being separated from each other.

And for the workpiece W that inserts clamping part 53a, for can holding workpiece W in the front of flex plate 55, flex plate 55 be bent to form bag portion 56 to the inside expand the ground bending laterally from stiff end 55a after.

Thus, so long as can enter the thickness of this bag portion 56, all can with the thickness of workpiece W irrespectively, make the front and the workpiece W butt of flex plate 55, holding workpiece W.

But, there is following situation to take place recently, promptly, in the hydraulic-transfer groove, produce current, one side make workpiece from its downstream upstream side shifting, one side carry out hydraulic-transfer because the relative velocity of the workpiece W when carrying out hydraulic-transfer accelerates, so this resistance to water-flow also strengthens, in experiment, workpiece W comes off in the hydraulic-transfer groove.

Therefore, the work holder that manufactured experimently and used thicker plate, has improved spring strength (rigidity) is as flex plate 55, but discovery becomes difficult to anchor clamps 51 workpiece loading and unloading W, and not too big variation of clamper intensity in contrast to this.

And,, therefore have the problem that manufacturing cost rises owing to thick leaf spring bending repeatedly must be formed.

Therefore, technical task of the present invention is workpiece easily to be installed with lower manufacturing cost, simple structure, and, do not come off even in conveying, be subjected to the external force workpiece yet.

Summary of the invention

In order to solve above-mentioned problem, work holder of the present invention, its flex plate one distolateral superimposed and be weldingly fixed on the rigid plate, elastic force clamping by above-mentioned flex plate is inserted into workpiece between rigid plate and the flex plate by the free end side from this flex plate, it is characterized in that, above-mentioned flex plate forms hook-shaped cantilever, the free end side of this hook-shaped cantilever is bent into acute angle to the inside, from its vertex, fixing distolateral formation is the plate spring part of free end to the reinforcing of rigid plate side, forms from this summit to free end to make the nip reflex part of (Sun い こ む) workpiece of its front-end edge.On above-mentioned rigid plate, be welded with from flex plate above-mentioned plate spring part is carried out the afterburning dull and stereotyped cantilever of reinforcement to the rigid plate side.

According to work holder of the present invention, because the free end side of flex plate is bent into acute angle to the inside, form hook-shaped cantilever, if therefore workpiece W is inserted the gap of flex plate and rigid plate, then workpiece is guided by the inclined-plane from the summit to free-ended reflex part, one side resist flex plate elastic force, push flex plate open and simultaneously enter, front-end edge is by the clamping of butt ground.

At this, if external force to the directive effect that workpiece is extracted, then since power forward ora terminalis hook and push open the directive effect of flex plate, so front-end edge further blocks workpiece, stop workpiece to come off.

And, because by strengthening using cantilever, above flex plate with plate spring part to the reinforcing of rigid plate side, so front-end edge blocks more firmly.

And, because a flex plate bent front ends side get final product, strengthen getting final product with dull and stereotyped with cantilever, process extremely simple, even so welding times increase a little, manufacturing cost can not increase substantially yet.

The specific embodiment

In this example, the shape by the improvement flex plate and is provided with strengthening part, realize and can workpiece easily be installed with this with not too high manufacturing cost, simple structure, and in hydraulic-transfer adeciduate purpose.

Fig. 1 is the key diagram of expression workpiece transporting clamp of the present invention, and Fig. 2 is the key diagram of expression work holder of the present invention.

Embodiment 1

Workpiece transporting clamp shown in Figure 11 since clamping be formed on the rear side of workpiece W flank R, carry this workpiece W, therefore on the pedestal B that is transferred machine or robot (not having diagram) conveying, the clamper C of the above-mentioned flank R of clamping is installed with the interval of regulation on the position corresponding with this flank R.

Work holder C forms the distolateral superimposed and be weldingly fixed on the rigid plate 2 of flex plate 3, and this rigid plate 2 is fixed on the pedestal B, is inserted workpiece W between rigid plate 2 and the flex plate 3 from its free end 3a side by the elastic force clamping of flex plate 3.

Rigid plate 2 is used than the high metal material of flex plate 3 flexural rigidities (EI value), even identical material also can improve rigidity by selecting the bigger material of thickness * width.

In addition, the size of rigid plate 2 has various according to workpiece W, for example can use the corrosion resistant plate of width 7cm * height 15cm * thickness 4mm.

Flex plate 3 uses the low metal material of specific rigidity plate 2 flexural rigidities (EI value), for example, uses the corrosion resistant plate of width 5cm * height 10cm * thickness 1.5mm.

And free end 3a side is by to the inside with the acute angle bending, from its summit 3b, stiff end 3c side becomes the leaf spring side 3d to rigid plate 2 side reinforcings with free end 3a, forms from this summit 3b to free end 3a to make its front-end edge 3e block workpiece W, become the hook-shaped cantilever of the doubling of reflex part 3f.

Because flex plate 3 is formed hook-shaped by bending, therefore the front-end edge 3e of free end 3a more is positioned at stiff end 3c side than summit 3b, from free end 3a side, from free end 3a to the limit the reflex part 3f of 3b form the inclined-plane of expansion laterally, rigid plate 2 also is the inclined-plane that its leading section 2a expands laterally.

Therefore, the leading section 2a of rigid plate 2 and the reflex part 3f of flex plate 3 form to the direction expansion that is separated from each other, and this part becomes the guide portion that workpiece W is guided sleekly between rigid plate 2 and flex plate 3.

In addition, because reflex part 3f forms the inclined-plane, therefore under the state that inserts workpiece W free end 3a is amplified when observing, the front-end edge 3e as the bight of the thickness of slab part of flex plate 3 blocks flank R ground butt as can be seen

And, on rigid plate 2, be welded with above flex plate 3 the reinforcement cantilever 4 of this plate spring part 3d to rigid plate 2 side reinforcings.In this example, this strengthens using the material identical with flex plate 3, the material of same thickness with cantilever 4.

And, since with plate spring part 3d to rigid plate 2 side reinforcings, so summit 3b is by to rigid plate 2 side reinforcings, its result, front-end edge 3e by being pressed on the rigid plate 2, when inserting workpiece W, can be made front-end edge 3e block workpiece W effectively by securely.

Like this, work holder C welds the flat rigid plate 2 of having only front end to expand laterally successively, be folded in half into hook-shaped flex plate 3 and flat reinforcement gets final product with cantilever 4, can reduce manufacturing cost.

And, get final product because 3 of flex plates form doubling, strengthen getting final product with cantilever 4 usefulness flat board, process very simple, even so welding times increase a little, manufacturing cost can not increase substantially yet.

And, making with metallic plate etc. under the situation of above-mentioned parts, can utilize waste material etc. to make according to its size, can further reduce manufacturing cost.

Above-mentioned is a configuration example of the present invention, below describes with regard to its effect.

When workpiece W is installed, shown in Fig. 2 (a), flank R is inserted between the rigid plate 2 and flex plate 3 of work holder C along the inclined-plane of the reflex part 3f of the leading section 2a of rigid plate 2 and flex plate 3.

At this moment, flank R is owing to by the guiding of the inclined-plane of the reflex part 3f of the leading section 2a of rigid plate 2 and flex plate 3, therefore, can insert between it sleekly.

And, shown in Fig. 2 (b), push the reflex part 3f of flex plate 3 open by the front end of flank R, plate spring part 3d is that the center is crooked laterally with stiff end 3c, reflex part 3f is that the center is crooked foldedly with summit 3b, and by its elastic force, front-end edge 3e is blocked the ground clamping with flank R.

Then,, make robot arm hold this anchor clamps 1, workpiece W is immersed in the hydraulic-transfer groove (not having diagram), then it is picked up in that flank R is clamped under the state on all work holder C that are installed on the transporting clamp 1.

During this period, workpiece W is subjected to the resistance by generations such as current, if the directive effect that external force comes off to the flank R that is held device C clamping, then with flank R block ground butt front-end edge 3e move to the direction that comes off, its result, the angle folding of the summit 3b of reflex part 3f enlarges, and summit 3b moves laterally.

Promptly, if flank R is come off, then not only must be shown in the dotted line of Fig. 2 (b), opposing plate spring part 3d and the elastic force of strengthening with dull and stereotyped cantilever 4, one side makes its crooked one side that summit 3b is moved laterally, but also must resist doubling flex plate 3 elastic force push the angle folding of reflex part 3f open.

And above-mentioned parts are crooked more, and its elastic force is strong more, and front-end edge 3e blocks flank R more firmly, therefore are not easy to make flank R to come off.

Therefore, even workpiece W is subjected to the resistance of current etc., external force is to the directive effect that flank R is come off from work holder C, and front-end edge 3e also can block flank R, so workpiece W is not easy to come off.

As mentioned above, the present invention goes for carrying the workpiece that can not be directly installed in conveyer or the robot or simultaneously carrying one side to carry out under the situation of certain processing, the fairly simple and purposes that fix effectively with this workpiece.
