Description
Technical field
The present invention relates to a kind of Wedge drive or pin key, this Wedge drive or pin key comprise slide receptacle, movable sliding part and actuator, and wherein slidingsurface is set between sliding part and the actuator.
Background technology
The Wedge drive that is also referred to as sliding part is mainly used to extruding force is transferred to punching press or forming tool, thereby can cut, bores a hole or be shaped in the special area of body part, these bodies partly have an inclination or undercut construction.In this arrangement, Wedge drive comprises at least one slide receptacle, movable sliding part and actuator.Have on the part that the slide receptacle of rigidity for example is connected to extruding or compression tools usually, in this pressure or compression tool, Wedge drive is used for carrying out punching press or shaping operation.If its slide receptacle is fixed in the top of compression tool, Wedge drive is called the top slider so, and this compression tool is connected on the extrusion head of motion.If its slide receptacle is connected on the bottom compression tool that is fixed on the rigidity extruding workbench, be called as the bottom slider so.Irrelevant with the part that the slide receptacle of Wedge drive is connected thereto, it has linear guide apparatus usually, and in this linear guide apparatus, movable sliding part can move back and forth, but similarly, it is firmly connected on the slide receptacle.Actuator is the form of rigid member usually, and this rigid member is connected on this part of compression tool securely, and slide receptacle is not fixed on this part.So actuator has the wedge part of inclination usually and is used as the actuator of movable sliding part.
Comprising that compression tool in fact vertically travels forward under the situation of (this is called driving stroke), be in sliding part on its rear positions and prop up, therefore make it to advance by its sloped position (wedge shape) towards operative orientation against the upright actuator of rigidity and supported.In this case, the gradient of the linear guide apparatus of slide receptacle and the sloped position of actuator are complementary, and therefore with respect to actual extrusion speed, related movable sliding part does not quicken.Therefore, only drive movable sliding part, and controllably promote this sliding part forward or outwards, thereby can carry out punching press or shaping work by compression tool.Outside compression tool moves to its lower dead point position and in the backward stroke motion that moves apart again each other of two parts, movable sliding part is by the elastic component of appropriate designs and be pushed usually on the home position of getting back to it, so this process can be restarted.The needed return force of the return movement of sliding part be generally real work power and sliding part weight 2% to 10%.Aspect this, the decision aspect of extruding force size is size, each gradient of the linear guide apparatus in the slide receptacle and sloped position and the cooperation of these surfaces and gradient and the structure of sliding part itself of actuator that is used for transmitting the surface of this pressure, and these surfaces are called slidingsurface.The pressure that will be transmitted is generally several 100KN to many 10,000KN.
Linear guide apparatus in the slide receptacle is used for guiding movable sliding part as far as possible very close to each otherly and bears bigger extruding force in doing so, and is provided long service life.In order to make workpiece can not have the cutting or the perforation of burr, therefore need be the tolerance of motion accuracy of the movable sliding part of 0.02mm to the maximum.If this tolerance is not being met, what the workpiece that is cut, bores a hole or be shaped with some alternate manners no longer can be with accurate aligning so concerns that one is placed on another, therefore having produced mistake in the basic housing construction and/or workpiece rubs against each other and means to have produced faster and corrode, the strength of machine body of being constructed has reduced, and may produce the noisiness that increases because sheet metal parts fluffs.For fear of all these shortcomings, especially the requirement in auto industry is, Wedge drive has extremely high motion accuracy and for good and all bears needed squeeze pressure or make them useful with respect to punching press or forming tool.
For needed motion accuracy is provided, therefore produced various designs, some of them will propose hereinafter.As an example, known have the sliding part guider of side sliding panel and with the actuator of arranged at right angles and the spiral cover plate that is used for keeping sliding part.The sort of sliding part guider really can bear very high extruding force and lateral thrust, but very complexity and manufacturing expense are very high for they, because need the manual coordination complexity of high level and expense to mate guiding clearance between these elements.The other problem of having found is to prevent that inadequately the sliding part guider from descending separately, and in this case, sliding part weight adds that backward connection power sum acts on the hold-down screw of cover plate and can make their overload very apace.In addition, the physical dimension of this sliding part guider is relatively large, and therefore this guider is not suitable for constructing small-sized sliding part.
The sliding part guider also is known as, the drive plate that has horizontal angle bar and arrange with the right angle.Different with above-mentioned sliding part guider, laterally the combination of sliding panel and cover plate causes the size of needed structure space to reduce, and therefore in particular, it also is possible as a result of constructing littler slider size.But will notice that bigger masterpiece is used on the hold-down screw of angle bar, and the result provided, had higher relatively accident hazard.In addition, the cooperation element is higher with the complexity and the expense of mating this guiding clearance, has therefore also caused extra-pay here.
The sliding part guider of employed other kind comprises horizontal slip and cover plate, and this plate tilts with 45 ° angle.Therefore they are disposed generally in the roof shape structure.This is possible below making, has promptly reduced structure width, because cover rod and one of sliding panel are arranged on another, rather than a next door that is positioned at another.But, notice that needed structure space is still very big, therefore may form less sliding part hardly.In addition, the tractive force that is produced has injurious effects to the hold-down screw of cover plate, and has caused the processing uncertainty of high level.
Other known structure comprises the sliding part guider with drive plate and has one or two post guiders of lining, thereby laterally maintains sliding part and prevent that it from dropping out.Use with lead of drive plate means, can't deny that ground only needs still small construction space relatively, and when using technique scheme in the prior art, the manufacturing that realizes obvious less expense is possible.But, will notice that the post guider can not compensate higher transverse pressure owing to the type of included structure.In addition, it can not carry any heavy especially sliding part, so these sliding parts have produced less extruding force and have been more prone to the influence of the trouble in the process of being squeezed.
For example EP 1 035 965 61 discloses another kind of sliding part guiding layout.This layout provides about the clamping of sliding part guider and has surrounded relation, and wherein actuator provides prismatic guide, and sliding panel is inserted between actuator and the sliding part.Included roof shape means, very high sliding part active force is possible, has produced the small construction space simultaneously, and has similarly produced point-device guiding clearance, therefore Wedge drive or sliding part guider are stable, and have long working life.But, will notice that in fact the manufacturing of clamping guider is complicated owing to need expensive cutting mechanics work to obtain accurately shape to be installed and as a result of is that expense is high.
For example EP 1259371B1, DE 198 60 178 C1 and EP 1 197 319 B1 also disclose other Wedge drive.
All above-mentioned design principles of the sliding part guider of Wedge drive have one or more sliding panel and transmit bigger generally extruding force, and similarly, the keeper of design is used for sliding part remained on and is above-mentioned set guide suitably.This sliding panel is used for for good and all being delivered to movable sliding part and therefore guaranteeing actual driving effect of advancing from slide receptacle and actuator by the operating pressure that compression tool applied.Keeper is used for linearly sliding part being remained on the sliding panel of slide receptacle, in this case, they for good and all guarantee needed motion accuracy, and are intended to possibility compensate for lateral thrust, and this lateral thrust results from shaping operation or cutting or the punching course.
Summary of the invention
Now, the objective of the invention is further to research and develop by this way the Wedge drive that is proposed in a kind of classified part as claimed in claim 1, so that provide a kind of guide of movable sliding part, compare with technical scheme of the prior art, this guide allows to have better motion accuracy, it can transform extruding force best, this extruding force affacts in punching press or the building motion, compared with prior art, this has compensated lateral thrust better, and compare with the possibility of the technical scheme of prior art, for Wedge drive provides longer service life.The present invention also seeks to provide, coordinate Wedge drive and more economical manufacturing become may the time, complexity and expense are reduced.
The Wedge drive that is proposed in the classified part for claim 1 has reached this purpose, because dovetail shape (dovetail-like) or prismatic guider are set between sliding part and the slide receptacle.For the sliding part of this Wedge drive, reached purpose of the present invention, because sliding part has dovetail shape or prismatic sidepiece.Other improvement of the present invention are defined out in the dependent claims.
Therefore a kind of Wedge drive or pin key are provided, in this driver or pin key, movable sliding part has dovetail shape or prismatic sidepiece, wherein slide receptacle is in the match form of part of correspondence, and the sliding part that therefore has dovetail shape or a prismatic sidepiece can join in the slide receptacle and can be directed to and be held in wherein.Sliding part that is provided by dovetail shape and prism shape and/or the surface on the slide receptacle are propped up each other and are leaned on respectively, in this case, rely on this surface in dovetail or the prism shape can carry the power of pointing to different directions, and this surface is oriented relative to one another to an angle without any problem ground.Dovetail shape means, be inserted into slide receptacle, in the corresponding reception structure that is shaped after, do not having under the situation of other measures, can prevent that movable sliding part from dropping out or laterally move.
Advantageously, slidingsurface is set on sliding part and/or the slide receptacle.In particularly preferred feature, dovetail shape or prismatic guider comprise at least two sliding panels, and these two sliding panels are arranged to be oriented relative to one another to an angle.Advantageously, the cross section of the sliding panel of dovetail shape or prismatic guider can be L shaped cross section.If sliding panel is set on all surface of sliding part and slide receptacle, be favourable by further finding so, slide against each other in this surface, therefore in each case, at least two sliding panels relative to each other arranging with an angle are set on sliding part and the slide receptacle.Cross section is that roof shape or L shaped sliding panel can advantageously be arranged to, and the sidepiece of their internal pinch provides the undercut construction that is in above-mentioned dovetail guide frame form owing to the outward-dipping sloped position of sliding panel.
Because sliding panel is provided respectively on the both sides of sliding part and slide receptacle simultaneously, wherein they are arranged symmetrically and are in L shaped or are in roof shape, therefore can obtain the shape of dovetail guider, therefore linear keeper that need not other, that expense is high is an advantageous particularly, possible.In addition, compare with the technical scheme of prior art, can reduce manufacturing expense significantly, because compared with prior art, under the situation of the mode of operation that does not have to influence unfriendly by any way Wedge drive, set parts are less, but allow to work more reliably and more safely under the situation that keeper is not provided, and have high motion accuracy.
Advantageously, dovetail shape or prismatic guider comprise effective locking (positively locking) connecting portion between sliding part and slide receptacle.The setting of this effective locking connecting portion provides compact unit, by this unit, even can transmit higher extruding force without any problem ground.In addition, because the effective locking relation in the zone of dovetail or prismatic guider and in the mechanical contact site between two parts wanting engaged sliding part and slide receptacle provides the power that will be transmitted in fact to transmit by the surface that contacts with each other, it can prevent that sliding part and slide receptacle from undesirably skidding off each other, this surface is oriented relative to one another to an angle, and in aspect this, rely on their angle orientation to help parts are kept together.
If slide receptacle has outstanding structure in the zone of the receiving system of the slidingsurface of sliding panel and/or sliding panel, so further be proved to be favourable.With respect to slide receptacle, this slip for sliding part provides bigger surface, therefore by the receiving surface of these expansions, can make extruding force obtain extraordinary transmission.
Advantageously, sliding panel can releasably be fixed on slide receptacle and/or the sliding part, especially is fixed on slide receptacle and/or the sliding part by hold-down screw.Sliding panel unclamps from slide receptacle and sliding part respectively and means, can change them when having produced wearing and tearing.Should be understood that the corresponding slidingsurface that disposes slide receptacle and sliding part by this way also is possible in principle, promptly under the situation of not inserting sliding panel, they can slide against each other.But, if under the situation that wearing and tearing take place, need to change slide receptacle and sliding part they itself, so this to be proved to be expense cheap and simple to operate with regard to processing, if this layout has releasable sliding panel, its replacing can be fast and without any difficulty so.
Advantageously, the sidepiece with sliding part of dovetail shape or prism shape has stayed surface as slidingsurface, is particularly useful for the connection of sliding panel.Two sliding panels are set in each case, be proved to be especially favourable, and these two sliding panels are arranged to be oriented relative to one another to an angle, because here can avoid difficultly adjusting four independent sliding panels, and this sliding panel is arranged to be oriented relative to one another to an angle.Only need adjust on a stayed surface separately for each sliding panel, thereby can change sliding panel apace.
Advantageously, the wedge guider is set between sliding part and the actuator.This layout provides, and can carry very large power, yet has relative small construction space, can carry out accurate, stable guiding for the sliding part on the actuator simultaneously when motion.
Advantageously, the wedge guider comprises two sliding panels, and these two sliding panels are arranged to be oriented relative to one another to an angle.Advantageously, these sliding panels comprise such material, and promptly this material helps to slide, and especially has the bronze of solid lubricant.Especially replaceably the setting that is fixed to the sliding panel on driver and/or the sliding part provides in a simple manner, promptly this plate can be replaced under the situation of wearing and tearing, when work, provide the best on actuator and sliding part surface to slide simultaneously, and this surface is engaged with each other.
Also proof advantageously is oriented relative to one another to an angle if dovetail shape or prismatic guider and wedge guider are provided on the sliding part.Relative to each other there is this layout of a plurality of angles to mean, especially can reduces the physical dimension size of Wedge drive, therefore compact unit is provided, even can use this unit under the restricted clearance condition in compression tool.
Also find advantageously, if dovetail shape or prismatic guider and wedge guider are set at two side located adjacent one another places of sliding part.This makes can improve the motion accuracy, but mainly simultaneously, compare with the technical scheme of prior art, can reduce the physical dimension size, and the technical scheme of the prior art is usually included in exercisable joint on the actuator and the exercisable joint on slide receptacle, and it is positioned at two sidepiece places that arrange relative to one another of sliding part.
Sliding part can have the 3rd side of contiguous other both sides, and the 3rd side has the receiving system that is used to receive machining tool.In this case, advantageously, the 3rd side has at least two undercut construction and/or groove, and this undercut construction and/or groove are used for inserting the prodger of the receiving system that is used to receive machining tool.Setting be used for receiving machining tool as this independent receiving system of perforation stamping machine can so that, without any changing this instrument difficultly, simply, because only need from the 3rd side of sliding part, pull down this receiving system, and change with another receiving system that for example loads different instruments.Can be by in sliding part, getting out other holes, this has eliminated the troublesome process of screwing on and backing out machining tool itself fully.At the 3rd side place of sliding part undercut construction is set and/or groove means, receiving system can be inserted into the there, for example, be pushed on the correct position, in this case, even do not need other to fix, because the optimum transfer of power is guaranteed, especially utilize undercut construction, because provide effective locking to connect.
The 3rd side of sliding part also can be provided with at least one wedge surface, in this case, so receiving system preferably has corresponding wedge surface, connects so that effective locking to be provided between the receiving system of sliding part and machining tool.Therefore can carry lateral thrust, and the transmission optimization that can exert all one's strength.
The mode of operation of Wedge drive generally includes driving stroke and return movement.During driving stroke, sliding part is outwards moved between the slidingsurface of actuator and slide receptacle, and this slidingsurface is arranged to the wedge shape form, in this case, slide receptacle and actuator can be driven by extrusion stroke towards motion with being perpendicular to one another.Aspect this, corresponding by the extruding force that compression tool applied with reaction force, Wedge drive applies this reaction force and works as cutting, perforation or postforming body part by it, wherein according to single slidingsurface all angles position relative to each other, it is assigned on the slidingsurface.Owing to be provided with slidingsurface, and this slidingsurface is arranged to be oriented relative to one another to an angle and this slidingsurface and is arranged and relative to each other is in roof shape or prism shape, therefore movable sliding part between slide receptacle and the actuator or on its slidingsurface automatically by centering.This can be compensated by making the manufacturing tolerance or other mistake that are produced, and therefore no longer have adverse influence simultaneously for sliding part provides very high motion accuracy and laterally steering.
At the return movement of sliding part, be called in the backward stroke, wherein compression tool moves apart each other, and therefore slide receptacle is moved apart actuator, sliding part is retracted back in the zone between slide receptacle and actuator.The dovetail shape of the guider between slide receptacle and sliding part allow again sliding part from the centering linear steering.When compression tool is removed, only by the weight of sliding part with act on withdrawal force on slide receptacle, sliding part and the actuator and be limited in the backward stroke or in return movement, act on this power on the sliding part.
With respect to the slidingsurface of in driving stroke, advancing against each other, the size of slidingsurface that advance against each other in this case, sliding part and sliding guide piece can be reduced, and is therefore finding aspect this that the slidingsurface of above-mentioned L shaped shape on the dovetail guider be fit closely.
Under the situation that top sliding part or Wedge drive are draped, the weight of sliding part acts on the surface of slide receptacle, and should prop up the sliding part slidingsurface of arranging against the dovetail guiding with effective locking relation in the surface, and the dispersion force (spreading force) of sensing downwards is applied on those surfaces of slide receptacle.But, because sliding part supports with respect to effective locking shoulder of slide receptacle, therefore those lateral thrusts are compensated, and can for good and all and stably be fixed to sliding part on the slide receptacle and are positioned on the sliding panel on sliding part and the slide receptacle.Therefore the hold-down screw of sliding panel does not bear any power of for example damaging it, does not especially bear tension force.Under the situation that other parts that are in the linear guide apparatus shape are not provided, can realize the guiding of sliding part by the dovetail guider along slide receptacle, and the accuracy of height and insensitive and manufacturing expense is cheap to lateral thrust, consequently, Wedge drive with compactness of very high-caliber motion accuracy, this Wedge drive is also insensitive to manufacturing tolerance.Owing to no longer need to clamp guide or other element, compare with the technical scheme of prior art, not only can reduce expense, and the reliability of this process is improved also and has reduced possible accident hazard.Because sliding part only need be pushed in the slide receptacle, compares with the technical scheme of prior art, the assembly of Wedge drive is simplified.The expensive grinding operation of expense that saves in the guide is possible, because the prismatic guide of slide receptacle, sliding part and actuator or dovetail guide are insensitive to manufacturing tolerance.Also produced very high motion accuracy from the centering effect about the carrying lateral thrust by what prismatic guide reached.Because the compact conformation of Wedge drive, so it not only is suitable for resulting small-scale structure space in compression tool, and as can knowing, it also is suitable for comprising the purposes of large-size.Therefore the prismatic guider or the dovetail shape guider that are arranged between sliding part and the slide receptacle can be used to equip small-sized, medium-sized and large-scale Wedge drive, and therefore the bigger scope of application is provided.With reference to accompanying drawing exemplary embodiment is described in further detail hereinafter, more fully to describe the present invention.

The specific embodiment
Fig. 1 shows the cutaway view of Wedge drive 1 or pin key (cotter key), and this Wedge drive or pin key comprise slide receptacle 2, sliding part 3 and receive the receiving system 4 of machining tool.The actuator that is connected on the sliding part 3 can not be seen in Fig. 1, but can find in the perspective view of Fig. 4.
Sliding part and slide receptacle link together by dovetail shape or prismatic guider 6.In this case, sliding part 3 has the part 30 of dovetail shape structure.It comprises two slidingsurfaces 31,32,33,34, and these two surfaces are separately positioned on the both sides mutually at a certain angle.In this arrangement, two slidingsurfaces 31 and 33 are less than two slidingsurfaces 32 and 34.Its reason is, in driving stroke, the extruding force that compression tool applied is delivered to sliding part by slidingsurface 32,34 from the slider receiving system, in this compression tool, has arranged Wedge drive.In the return movement or backward stroke (strake) motion of compression tool, sliding part is by 31,33 withdrawals of two slidingsurfaces, in this case, on sliding part, apply a much smaller power, therefore just enough for these less sizes of this slidingsurface.
In principle, such protuberance is not set also to be fine, but, in this case, by such protuberance 35, improved the mutual maintenance of sliding part and slide receptacle significantly, this protuberance 35 joins in the corresponding recess 25 of slide receptacle with effective locking relation.
As from can further seeing Fig. 1, sliding panel is set on slide receptacle and the sliding part, to form corresponding slidingsurface 21 to 24 and 31 to 34 respectively.The cross section of the sliding panel 26,27 on the slide receptacle 2 is L shaped cross sections, and independent smooth sliding panel 36,37,38,39 is connected on the respective surfaces of sliding part, as from can seeing better Fig. 3.L shaped sliding panel 26,27 is fixed on the slide receptacle by hold-down screw 28,29.Sliding panel 36 to 39 also is fixed on the sliding part by corresponding hold-down screw, and is shown in Figure 1 but these do not have.
Thisly releasably sliding panel is respectively fixed to setting on slide receptacle and the sliding part, when wearing and tearing are being arranged, can changes sliding panel without any problem ground.Hold-down screw is disposed in the sliding panel with the relation that sinks to, so the setting of hold-down screw does not stop slidingsurface against each other slip.
As especially from can being clear that the sectional elevation of Fig. 1, slide receptacle is protruding in the zone of dovetail shape guider, thereby provides enough big slidingsurface 22,24 for supporting and slip on sliding part 3.
As from can further seeing Fig. 1, the receiving system 4 that is used for receiving machining tool is provided with T shape protuberance 40, and sliding part 3 is provided with corresponding T connected in star 41.Arrange that by this receiving system of machining tool can easily be pushed in the T connected in star 41, therefore fixing simply is possible with remaining on the sliding part reliably.Without T connected in star and T shape protuberance, also be possible but in that zone, the wedge shape with corresponding recesses and protuberance is set, therefore the centering effect can also be provided and in that zone, carry lateral thrust.But, the motion of sliding part with respect to receiving system is not provided, under most situation, provide T connected in star and T shape protuberance just enough.
Fig. 2 show slide receptacle and sliding part details, from following perspective view of looking obliquely.These two elements illustrate with being separated, therefore can see the sliding panel 26,27 of slide receptacle 2 and the dovetail shape part 20 of slide receptacle.In addition, can also be clear that the part 30 of sliding part, this part 30 is that dovetail shape structure and sliding panel are fixed to the upper, and also is expressed out by its of screw is fixing.As from the perspective exploded view of Fig. 3 even seeing better, each sliding panel is fixed to respectively on slide receptacle and the sliding part by three hold-down screws.Sliding panel has the corresponding hole that is used for receiving hold-down screw.
Fig. 2 and 3 also shows the wedge shape receiving surface 300 that is used to be connected on the actuator 5, and this actuator can be in sight in Fig. 4.Wedge shape receiving surface 300 is divided into two and have two slidingsurfaces 301,302, and each sliding panel is connected on these two slidingsurfaces, but sliding panel can not be in sight in Fig. 2 and 3.Wedge shape receiving surface 300 with respect to dovetail shape part 30 and sidepiece with T connected in star 41 at angle, this T connected in star 41 is used for receiving the receiving system of machining tool, therefore for sliding part provides extremely compact structure shape, there is not obsolete side surface in fact.This also can be seen from the perspective view of the Wedge drive that assembles 1 shown in Figure 4 particularly, and in this Fig. 4, slide receptacle, sliding part, actuator and the receiving system that is used for machining tool are assembled.Can also see aspect this, return clip 7 by useful effect actuator and sliding part are linked together.In the motion of the backward stroke of compression tool, they are used for carrying secretly better sliding part.Useful effect is returned clip 7 and is bonded on sliding part and actuator in opening, recess or the groove that is arranged on the there.
Can be clear that from Fig. 5 for this purpose, useful effect is returned clip 7 and had ledge 70, this ledge 70 can be bonded in the corresponding recesses of actuator.Can also see that from Fig. 5 sliding panel 303,304 is fixed on the slidingsurface 301,302 by hold-down screw 305.
The perspective view of the Wedge drive 1 of Fig. 6 (Fig. 6 has changeed 90 ° with respect to the view of Fig. 4) shows the view of the receiving system 4 that is used for receiving machining tool.To see aspect this that receiving system 4 is provided with corresponding wedge surface, this corresponding wedge surface comprises two slidingsurfaces 43,44, and this slidingsurface can slide on the corresponding wedge part 50 of actuator 5.
From the side view of Wedge drive shown in Figure 71 even can see better, the part 30 of dovetail shape structure, wedge shape receiving surface 300 and the 3rd sidepiece with T connected in star 41 are arranged to be oriented relative to one another to an angle respectively, and this T connected in star 41 is used for receiving this receiving system 4 of the machining tool that is used for sliding part 3.With respect to vertical line or horizontal line also at angle, with dotted line in Fig. 78,9 represent respectively by this vertical line or horizontal line in the sidepiece of sliding part each.Again can be clear that Wedge drive has extremely compact structure shape here.
Respective side in the section of Wedge drive 1 shown in Figure 8 also shows the spring part 10 that is gas pressure spring shape.In the backward stroke motion of machining tool, it is used for making sliding part to be withdrawn on its starting position.Therefore this helps the retraction movement of sliding part when backward stroke moves, execution work stroke more apace again.But, each self-structure according to Wedge drive, save this spring part even also be possible, especially be provided with when being in useful effect and returning the useful effect Returning equipment of particular design of clip 7 forms, for example be in the form of useful effect Returning equipment, can save this spring part with rolling friction part.
From the perspective view of the Wedge drive 1 of Fig. 9, can also be clear that, since arranged suitably it three sidepieces (part of dovetail shape structure join to slide receptacle in), be used to receive the wedge shape receiving surface that the T connected in star and being used for of the receiving system 4 of machining tool cooperates with actuator 5, so sliding part has extremely compact structure.
As shown in Figure 10, the perspective view of the Wedge drive 1 of looking from below (actuator 5 is removed) shows, sliding panel 303,304 can have such length, be their receiving systems 4 of also being bonded on machining tool wedge surface 42 slidingsurface 43,44 below, in other words, except having only sliding panel 303,304, more sliding panel is not set, so this layout provides the integral surface that matches with the corresponding wedge part 50 of actuator 5 here.
The receiving system that can see machining tool the perspective view from top from Wedge drive 1 again is removed sliding panel 303,304 afterwards, as shown in Figure 11.Be apparent that also that in this respect hole 305 and corresponding hold-down screw (yet this screw is not illustrated among Figure 11) by being provided with in the sliding panel 303,304 provide to suitable the fixing of the receiving system of machining tool.Utilize this method, the receiving system 4 that can also further improve machining tool is fixing to sliding part, and provides even more stable unit.
Above-mentioned sliding panel and slide receptacle on sliding part and the actuator preferably include the bronze with solid lubricant, thereby make the slide unit of tackling mutually against sliding particularly well each other.Should be appreciated that, in principle, other material that use is used for sliding panel also is possible, wherein the friction than low degree in the surface of sliding against each other means, in the driving stroke and backward stroke of the compression tool of having arranged this Wedge drive, the especially best motion of sliding part in Wedge drive is possible.
Except the embodiment of Wedge drive shown in described above and the figure, that have dovetail shape or prismatic guider, it also is possible forming many other embodiment, in these other embodiment, the dovetail shape slidingsurface is arranged between slide receptacle and the sliding part, and perhaps prismatic guide is set between sliding part and actuator and slide receptacle and the sliding part.Compared with prior art, this has improved each accuracy of the motion of sliding part between slide receptacle and actuator significantly, and lateral thrust is absorbed and the foozle of slide receptacle, sliding part and guide is compensated.A dovetail shape or prismatic guider only are set between slide receptacle and sliding part, make and to save the more multi-part that helps guide effect, and therefore compared with prior art, make the manufacturing expense of Wedge drive obviously reduce.
