the specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1 to Figure 3, a kind of clamping pay-off 1 that the utility model embodiment provides, automated exchanged cutter and feeding while being mainly used in the cutting of drawing and forming material, the Drilling operations such as five metals, watchband.Comprise base plate 11 and be arranged on the first holder 12 of can be movable relatively on base plate 11 and the second holder 13, the first holders 12 are provided with the first clamping assembly 14, the second holders 13 the second clamping assembly 15 is installed.Base plate 11 is fixed for the installation of whole clamping device 1, the stability while guaranteeing to use; And the first holder 12 on it and the second holder 13 can relative motions, thereby realize the conveying for the treatment of rapidoprint.In the present embodiment, the second holder 13 is also connected with and drives the feeding driven unit 17 self moving, the second holder 13 can move back and forth under the driving of feeding driven unit 17, material to be processed is delivered to the first clamping assembly 14 to be clamped, thereby realize processing, by automatic transport, improved the efficiency of processing.
As shown in Figure 1 to Figure 3, the first clamping assembly 14 and the second clamping assembly 15 include holder 141, are placed on fixed mould 142, the movable block 143 in holder 141 and pass through fixed mould 142 and press from both sides the 144 binder folder groups that form by a plurality of binders, the bottom of every binder folder 144 is all connected with movable block 143 by connecting rod 145, and the first movable block 143 of the first clamping assembly 14 and the second movable block (not shown) of the second clamping assembly 15 are connected with compression driven unit respectively.By such setting, compressing driven unit can drive movable block down to move, just can realize material sandwiched to be processed is pressed between movable block and fixed mould 142, and when movable block up moves, just the material to be processed being folded between movable block and fixed mould 142 can be unclamped, motion, has realized and has treated the clamping of rapidoprint or unclamp and so forth.In concrete application, compressing driven unit can directly be connected with movable block, realizes the function that drives movable block motion, also can will compress driven unit setting separated with movable block, again by adopting other member to carry out transmission of drive force, can realize equally the function that drives movable block motion between the two.The position that compresses driven unit installation can compress the mode connecting between driven unit and movable block or require concrete setting according to reality, is not limited only to position set in the present embodiment.Adding man-hour, both fasten the first clamping assembly 14 and the second clamping assembly 15 material clip to be processed jointly, and the stability of clamping is high, can not become flexible, and has guaranteed to add the precision in man-hour.Can according to the needs setting of actual conditions, pass through the number of the binder folder group of fixed mould 142 in addition, when so just can realize many materials to be processed, be fixedly clamped, improve production efficiency.
A kind of clamping pay-off 1 that the utility model provides, the row of passing through the binder folder group that fixed mould 142 is fixedly connected with the first movable block 143 in the first clamping assembly 14 can be selected to arrange with the row of passing through the binder folder group that fixed mould 142 is fixedly connected with the second movable block in the second clamping assembly 15 according to the actual needs, to realize the demand that can compress many materials to be processed simultaneously.And adding man-hour, both fasten the first clamping assembly 14 and the second clamping assembly 15 material clip to be processed jointly, have guaranteed the stability clamping.In addition, the second holder 13 is also by the effect of feeding driven unit 17, can move around, the second clamping assembly 15 can be moved around by relative the first clamping assembly 14, and the first clamping assembly 14 and the second clamping assembly 15 clampings or the state unclamping are to realize under the control of corresponding program, thereby have realized the function of self-feeding, for saved man power and material's input when actual production is processed, improved the efficiency of producing, for enterprise has created profit.
Particularly, as shown in figures 1 and 3, the both sides that holder 141 is relative are provided with for being installed with the clamping cap 1411 of fixed mould 142, in binder, press from both sides on the fixed mould 142 of 144 both sides and all offer for holding the holddown groove 1421 of material to be processed, the top of binder folder 144 is provided with the inclined-plane for pushing.Like this, fixed mould 142 can be fixed by clamping cap 1411, prevents that it is loosening; Also be convenient to dismounting and change.When needs are fixed and clamped material to be processed, material to be processed is placed in the holddown groove 1421 between fixed mould 142 and binder folder 144, then compress driven unit and drive down motion of binder folder 144, at this moment the inclined-plane along with binder folder 144 down pushes material to be processed, has just realized material to be processed is pressed abd fixed between fixed mould 142 and binder folder 144.Inclined plane shape is arranged to in the top of binder folder 144, when being fixed, not only can plays like this effect of guiding, can also be along with the variation on inclined-plane, the more firm stable that material to be processed is fixed; In addition, binder folder 144 can be fixed the material to be processed of its relative both sides simultaneously, has improved the radical of disposable clamping, has further improved and has produced efficiency.The inclined-plane that binder presss from both sides 144 tops can be plane, also can be the curved surface of smooth transition etc.
Preferably, as shown in Figure 3, the top of binder folder 144 is " V " type, and inclined-plane is burnishing surface.Like this, not only realized the function that both sides can both be fixed; And inclined-plane is set to burnishing surface, can when being fixed, slide smoothly, be also convenient to production and processing.
Particularly, as shown in figures 1 and 3, binder folder group at least arranges a row, often drains into two binder folders 144 are set less, and holddown groove 1421 at least arranges two.Like this, met the function of basic clamping, every row pressure feed collet group that arranges, just can on the fixed mould 142 of its both sides, offer two holddown grooves 1421, and, have owing to often draining into rare two binders folder 144, like this, when compressing, can compress material to be processed simultaneously, make compression more firm, guarantee the stability clamping.Certainly, the row of binder folder group also can be set according to actual requirement, as two rows, three rows or more, to realize the function that clamps many materials to be processed simultaneously.
Preferably, as shown in Figure 3, binder folder group is set to two rows, and every row is provided with two binder folders 144, and holddown groove 1421 is set to four.In the present embodiment, binder presss from both sides group and is set to two rows, and every row arranges two described binders, and holddown groove 1421 is set to four, like this, when one action, can be fixed four materials to be processed simultaneously, has improved the efficiency of producing.
