Description
Relate generally to of the present invention be used for such as two objects are temporarily clipped together bond or holding workpiece so that the clamp welding, the active grab that particularly moving chuck can advance fast or advance by the little increment that length can be selected.The principle of bar type clamp is old and knows.In recent years, be equipped be used for final workpiece pressing move core type toggle link operating grip, for example United States Patent (USP) 4,088,313 of Pilsen (Pearson) and Wallace's (Wallace) United States Patent (USP) 4,563,921.The shortcoming of this original technology is to adjust moving chuck need cross sizable distance, very inconvenient, also inaccurate.At moving folder with before decide finally to compress object between the chuck, moving chuck is thrown off and free activity often fully.Sometimes the demand of going back during operation helps another people.
The principle of bow type clamp also is old and knows.Be equipped with on the bow type frame and decide chuck, moving chuck is contained on the screw mandrel, rotary screw rod can make chuck to decide chuck near or leave therefrom.The shortcoming of this device is to clamp before workpiece or the several workpiece, and moving chuck will advance sizable distance, and the screw mandrel of the moving chuck of supporting will change a lot of circles.Usually, the handle of rotary screw rod is the slidingtype handle, and it can do transverse movement with respect to the screw mandrel moving direction, so that screw mandrel revolution half-turn just can be slid forward and backward along screw mandrel.Need rotate in the place of position anxiety but 360 ° of whole circles when rotating of the impossible again work of handle, this is an advantage.But the slip of handle transposition is inconvenient and trouble.The bar type clamp that adopts a rhizoid bar to adjust has same problem.
The needed clamp of people is that its moving chuck can the changeable distance of fast moving be clamped workpiece, and the operator only just can comprehensively operate at any time with a hand.
In general, according to the present invention, bow type and bar type clamp apply to clamp rapidly and accurately a workpiece especially.Bar type clamp comprises that one is decided a chuck and a moving chuck relative with deciding chuck.Moving chuck is connected to an end of sliding bar, and sliding bar is movably, is being with moving chuck to draw close and leave with it and is deciding chuck.Utilize the operation of fastening plate machine handle, unidirectional thrust unit releasably with the sliding bar interlock, chuck is advanced to deciding chuck.Unidirectional thrust unit can not make sliding bar unclamp and chuck is left decides chuck.Moving chuck back moves when unidirectional thrust unit unclamps and is finished by manual.Unless during skew and first brake bar of sliding bar interlock be under the state that gets loose with sliding bar, hamper moving chuck from deciding the motion that chuck returns.Therefore, need all unclamp the unidirectional thrust unit and first brake bar for making chuck make return movement.Plate machine handle need promote second bar and advance sliding bar, and second bar is to drive sliding bar when deciding chuck and move with surperficial interlock of sliding bar.Plate machine handle is whenever finished once action, and second bar is just pushed back original position by the strength of spring, slides on the sliding bar surface during the second bar return movement.
Bow type clamp comprises that one is decided a chuck and a moving chuck relative with deciding chuck.Moving chuck is connected to an end of sliding bar, and sliding bar is movably, is being with moving chuck to draw close and leave with it and is deciding chuck.Bow type frame comprises a longitudinal rod parallel with sliding bar; First arm that is horizontally placed on longitudinal rod is used for supporting to decide chuck.Second arm that is horizontally placed on longitudinal rod is used for supporting slidably sliding bar.Fastening plate machine handle, unidirectional thrust unit advances to deciding chuck with regard to releasably make chuck with the sliding bar interlock.Unidirectional thrust unit can not make sliding bar and moving chuck become flexible and leave and decide chuck.Moving chuck back move when unidirectional thrust unit unclamps by manual decide into.First bar unless be offset with the sliding bar interlock is under the state that gets loose with sliding bar.Hampering moving chuck leaves and decide the action that chuck returns: plate machine handle need promote second bar and promote sliding bar.Second bar drives sliding bar when moving forward with sliding bar surface interlock.Second bar is pushed back original position by the strength of spring, slides on the sliding bar surface during this swivel motion of second bar.There is not the handle that rotates on perpendicular to moving chuck moving direction as original technology.
Therefore, providing improved quick-action bar type and bow type clamp, is a target of the present invention, and wherein moving chuck can move past changeable distance soon.

Fig. 9 is the top view of quick-action bow type clamp shown in Figure 8.
Figure 10 is the right view of quick-action bow type clamp shown in Figure 8.
Figure 11 is the action of expression quick-action bow type clamp and be similar to the partial enlarged drawing of Fig. 8.
With reference to Fig. 1-7, quick-action bar type clamp 10 contains a moving chuck 12 that is connected to sliding bar 14.Sliding bar is supported on the slotted eye 16(Fig. 4 that passes plate machine handle-Handleset 18 slidably) in.
Plate machine handle-Handleset 18 comprises that 19, one of the housings of a grooved hole break-through are contained on the housing 19 to be contained on the housing 19 the handle 20 of slotted eye 16 1 sides and one and decides chuck 22 at slotted eye 16 opposite sides.Plate machine handle 24 usefulness pivot pins 26 are contained on the housing 19 rotationally near on the position of slotted eye 16.Move chuck 12 and decide chuck 22 and be oppositely arranged.
Represent very clearly among Fig. 4 that handle 20 is local dents, in order to peace plate putting machine handle in groove 28.Second groove 30 on the housing 19 separated slotted eye 16.Catch bar 32 is suspended on the sliding bar 14, and sliding bar was worn from the opening 34 of catch bar 32.Spring 36 is compressed between the surface 38 of catch bar 32 and groove 30, makes the upper end 40 of catch bar 32 plate for forcing machine handles 24.40 one-tenth fork-shapeds in upper end of plate machine handle 24 are on sliding bar 14.The strength of spring 36 is pressed onto plate machine handle 24 on the inner surface 42 of housing 19, forms dormant state.Under dormant state, catch bar 32 is the vertical direction of motion with sliding bar 14 shown in the arrow 44 when operation.Plate machine handle 24 all makes spring 36 skews around any motion of pivot pin 26 on arrow 44 directions.
It should be noted that in the standby position that Fig. 4 represents catch bar 32 is substantially perpendicular to the longitudinal axis of sliding bar 14, and brake bar 46 engages with sliding bar 14 that part of be the longitudinal axis that is horizontally placed on bar 14, but be not orthogonal to its longitudinal axis.In this state, if along the direction shown in the arrow 44 moving chuck 12 is applied a power, sliding bar 14 just can pass hole 34 And in the catch bar 32 and pass spring 36 and move freely.Because when direction shown in the arrow 44 adds a power to moving chuck 12, the bias voltage of brake bar 46 antagonism springs 54 can freely swing, and this of 46 pairs of sliding bars of brake bar do not move and can present obstruction, and moving chuck 12 just can continue to draw close to deciding chuck 22.
But, in the standby position that Fig. 4 represents, if when the rightabout shown in the arrow 44 applies a power to moving chuck 12, the surface that the edge of the opening 48 on the bar 46 blocks sliding bar 14, if there is not other active force, can not as hereinafter proving absolutely, draw back moving chuck from deciding chuck 22.And when pressing brake bar 46 to make spring 56 compressions along the direction plate of arrow 44, with regard to stretchy sliding bar 14, chuck 12 is left decide chuck 22.This strength makes the termination 50 of bar 46 vertical with the predetermined moving direction of sliding bar.The opening 48 that sliding bar 14 just can pass brake bar 46 is free to slide at both direction.
Along the handle of direction pulling trigger shown in the arrow 44 24, can little by little make sliding bar 14 and be contained in moving chuck 12 above it and draw close and decide chuck 22.Rotation around pivot pin 26 when oppressed, will take place in plate machine handle 24 between operator's hand (not shown) and handle 20, moved along the direction of arrow 44 in the termination 40 of plate machine handle 24.This just causes catch bar 32 around its upper end (Fig. 4) swing, so catch bar 32 is just no longer perpendicular to the predetermined moving direction 44 of sliding bar 14.The swing of catch bar 32 is spring 36 compressions, the surface that the while also makes the edge in the hole 34 of passing catch bar 32 block sliding bar 14.Because interlock no longer perpendicular to the predetermined moving direction 44 of sliding bar 14, has taken place in catch bar 32 thus.Continue movable plate machine handle 24, catch bar 32 will move along the direction of arrow 44.Spring 36 is further compressed in this motion, in this process, because the interlock between bar 32 and the bar 14, makes bar 14 and the moving chuck 12 that connected is drawn close to deciding chuck 22.When spring 36 compresses fully, perhaps in another kind of structure, when plate machine handle 24 was run into the surface 58 of handle 20, this one stroke of plate machine handle 24 just made chuck 12 reach maximum advance distance.
But plate machine handle 24 can reduce its stroke when moving arbitrary less radian, thereby reduces the distance that moving chuck 12 moves in a stroke, and this distance is proportional with the angle of plate machine handle stroke.Can take the stroke of arbitrary size of several plate machine handles 24 continuously,, perhaps the workpiece (not shown) between them be clamped solidly up to together chuck 12,22 And.
Horizontal pin 60 passes the free end of sliding bar 14, and when the direction of brake bar 46 at arrow 44 is pressed, and when drawing back from deciding chuck 22 with the moving chuck 12 of handgrip, pin 60 can prevent from sliding bar 14 is pulled out from slotted eye 16.Should be noted that console panel machine handle 24, can not make sliding bar 14 do any moving at the rightabout of arrow 44.
Only, represented to be contained in the protection liner plate 62 on chuck 12 and 22 as example.Also be as an example, moving chuck 12 and plate machine handle-Handleset 18 all are to do into two, and And is fixed together with screw 66.In the explanation of the embodiment of the invention (Fig. 4), sliding bar 14 has rectangular cross section.In other embodiments of the invention, sliding bar 14 can be an Any shape, for example square, garden shape, triangle, the opening 34,48 of bar 32,46 adopts corresponding shape respectively simultaneously, so as with sliding bar 14 interlocks.
In a word, want piece-holder between chuck 12,22, moving chuck 12 is to decide drawing close of chuck 22, both can be only move as one-time continuous along the direction promotion chuck 12 of arrow 44, but console panel machine handle 24 finished the stroke that a succession of length depends on the operator again.Can adopt long stroke earlier, use short stroke subsequently again, be used for workpiece is applied required pressure, make in the operation that chuck draws close at this, whenever push away further, brake bar 46 will stop sliding bar 14 any moving backward.When brake bar 46 blocked bar 14, plate machine handle 24 unclamped.So spring 36 just back into position shown in Figure 4 to plate machine handle 24 and catch bar 32, prepare the another one stroke.Whenever the operator wishes to make chuck 12 to recess when deciding chuck 22, for example, unclamp workpiece or open bar type clamp, only need when pressing the rightabout pulling chuck 12 of arrow 44, to withhold brake bar 46 with compression spring 54 by the direction of arrow 44 to accept workpiece.
Should be noted that and to finish with that hand of holding bar type clamp 10 whole operations of plate machine handle 24 and brake bar 46.When several fingers centers on and holding plate machine handle 24 and handle 20, can press brake bar 46 with forefinger or middle finger on demand.
Can know in Fig. 2 and Fig. 3 and find out that the profile of quick-action bar type clamp 10 of the present invention is flat basically, it is few to take up space, and can use in the place of operating difficulties.Sliding bar 14 can adopt various length.
In Fig. 1-4, plate machine handle-Handleset 18 is done into two, is fixed together with screw 66, and plate machine handle 24 is whole, is inlaid in the groove 28 of handle 20.(Fig. 5-7) in another embodiment, a quick-action bar type clamp 110 of the present invention contains the plate machine handle-Handleset 118 of an integral body, and it does not have inner groove, and also containing one is the plate machine handle 124 of U type basically.When plate machine handle 124 was pressed to handle 120, as obviously seeing in Fig. 7, handle 124 moved along the direction of arrow 144, rides on the handle 120.The termination 150 of brake bar 146 can be rotated in the recess 152 of plate machine handle-Handleset housing 119.Plate machine handle 124 can rotate the flat board 170 that ， And contain half garden shape around axis 126, and it is inserted in the groove 172 of respective shapes of housing 119.
The operation of the bar type clamp of Fig. 5-7 is identical with the embodiment of Fig. 1-4, notice that label among Fig. 5-7 is to add 100 corresponding to being used for the number of key-drawing 1-4.
Comprise the moving chuck 212 that is fixed in sliding bar 214 with reference to Fig. 8-11, bow type clamp 210.Sliding bar 214 is to be bearing in slidably in the slotted eye 216 that passes bow type frame 218.
It should be noted that in standby position shown in Figure 8 catch bar 232 is substantially perpendicular to the longitudinal axis of sliding bar 214, and brake bar 250 engages with sliding bar 214 that partly, be the longitudinal axis that is horizontally placed on bar 214, but be not orthogonal to its longitudinal axis.In this state, if when the direction shown in the arrow 264 applies a power to handle 228, opening 234 and spring 236 free ends that sliding bar can pass catch bar 232 move.Because with respect to moving direction 264, brake bar 250 tilts, and this of 250 pairs of sliding bars of brake bar do not move and can present obstruction, and moving chuck 212 just can continue to draw close to deciding chuck 226.
But, shown in standby position in, if when the rightabout shown in the arrow 264 applies a power to handle 228, be subjected to the promotion of spring 258, the edge of opening 252 blocks the surface of sliding bar 214, if there is not other active force, be impossible as hereinafter will proving absolutely, chuck 226 draws back from deciding moving chuck.Can make sliding bar and moving chuck 212 from deciding the other active force that chuck 226 draws back, withhold brake bar 250 with compression spring 258 along the direction of arrow 264 exactly.This just makes the termination 254 of bar 250 vertical with the predetermined moving direction of sliding bar 214.The opening 252 that sliding bar just can pass brake bar 250 is free to slide on both direction.
Along the handle of direction pulling trigger shown in the arrow 248 242, can little by little make sliding bar 214 and be contained in moving chuck 212 above it and draw close and decide chuck 226.Rotation around pivot pin 244 when oppressed, will take place in plate machine handle 242 between operator's hand (not shown) and transverse arm 224, moved along the direction of arrow 264 in the termination 246 of plate machine handle 242.This just causes catch bar 232 around its upper end 266 swings, so catch bar is just no longer perpendicular to the predetermined moving direction 264 of sliding bar 214.The swing of catch bar 232 makes spring 236 compressions, also makes the edge in the hole 234 of passing catch bar 232 block the surface of sliding bar 214 simultaneously, thereby catch bar 232 is moved along direction 264.This moves further compression spring 236, in this process, because the interlock between bar 232 and the bar 214, makes bar 214 and the moving chuck 212 that connected is drawn close (Figure 11) to deciding chuck 226.When moving of bar 232 blocked by the surface 268 of transverse opening 230, when perhaps plate machine handle 242 was run into block (not shown) on the frame 218, this one stroke of plate machine handle 242 just made chuck 212 reach the advance distance of maximum.
But plate machine handle 242 can reduce its stroke when moving arbitrary less radian, thereby reduces the distance that moving chuck moves, and this distance is proportional with the angle that plate machine handle moves.The stroke of arbitrary size that can take several plate machine handles 242 is continuously perhaps clamped the workpiece (not shown) between them up to chuck 212,226 And together solidly.
In a word, want piece-holder between chuck 212,226, moving chuck 212 is to deciding drawing close of chuck 226, both can be only move as one-time continuous, but console panel machine handle 242 is finished the stroke of a succession of length again, depends on the operator along the direction driving handle 228 of arrow 264.Can adopt long stroke earlier, come workpiece is applied the pressure of expection subsequently again with short stroke.Make in the operation that chuck draws close at this, whenever push away further, brake bar 250 will stop any of sliding bar 214 to move backward.When brake bar 250 blocked bar 214, plate machine handle 242 unclamped, so spring 236 just back into position shown in Figure 8 to plate machine handle 242 and catch bar 232, prepared another stroke.Whenever the operator wishes for example, is unclamped workpiece or opens bow type clamp to accept workpiece when deciding chuck 226 and recess moving chuck 212, only needs to pull handle in 228 in arrow 264 opposite directions, pushes brake bar 250 by the direction of arrow 264.
Should be noted that and to finish with that hand of holding bow type clamp 210 whole operations of plate machine handle 242 and brake bar 250.When several fingers centers on and holding plate machine handle 242 and transverse arm 224, can press brake bar 250 with thumb on demand.
Can know in Fig. 9 and Figure 10 and find out that the profile of quick-action bow type clamp 210 of the present invention is flat basically, it is few to take up space, and can use in the place of operating difficulties.Bow type frame 218 can adopt the used any common shape of original bow type clamp, and the length of transverse arm 222,224 and they all are variable with respect to the angle that sliding bar 214 moving directions are presented.
So can find out, the top target of stating, comprise by those shown targets of front explanation and be effectively achieved And and owing to can do some to said structure and change also without prejudice to the spirit and scope of the present invention, the whole contents that are included in above-mentioned explanation or the accompanying drawing are interpreted as just illustrating, and not limit by this.
