Description
Technical field
The present invention relates to a kind of braiding tool bar, be fixed on the braiding tool device on the FX of main body with main body and at least one, wherein, main body has the seamed edge adjacent with the braiding tool device.
Background technology
In order to allow braiding instrument of the same type in braiding machine, especially in the same manner motion in warp loom is arranged braiding instrument of the same type at the braiding tool bar.Such sley bar extends past the working width of braiding machine.Therefore sley bar may have several meters length fully.Now working width and thereby sley bar length can be 6 m.
In each lopping circulation, must accelerate and brake this class braiding tool bar.For this reason, people make every effort to keep the quality of braiding tool bar as far as possible little.Replace early stage widely used light metal, such as magnesium or aluminium is that the main sley bar of being made by fibre reinforced plastics that uses wherein often uses carbon fiber as fortifying fibre in the recent period.
The braiding instrument concentrates in together in groups.They remain in so-called bearing or the braiding tool support, and described bearing is fixed in FX on the braiding tool bar.These braiding tool supports fixing braiding instrument in the ashbury metal of being everlasting, plastics or light metal.They concentrate in together the braiding instrument, and width reaches 1 inch (Zoll) or several inches.The fixing usually thus realization of braiding tool support on the braiding tool bar namely, guide the eye that passes in the braiding tool support with set bolt, and this set bolt is screwed in the threaded bore in the FX of braiding tool bar.Can make like this threaded bore, namely after cutting screw thread or can be in advance screwing element be positioned on the predetermined position making when weaving tool bar in the boring of processing.Threaded bore is with corresponding arranged in patterns.Only obtain to weave the mobile possibility of tool support owing to the gap of the set bolt in the eye of bearing.
In addition, the defective of this way is, threaded bore destroyed the braiding tool bar main body structure and thereby weakened the braiding tool bar.Correspondingly, must in FX, establish the sley bar material of q.s, in order to satisfy requirement of strength.This has limited the operating rate of braiding tool bar.High operation speed requires the quality of braiding tool bar very little.
Summary of the invention
Technical problem to be solved by this invention is that sley bar can be used as far as possible widely.
This technical problem starts in the braiding tool bar of described type at this paper and solves thus, that is, the braiding tool device clamps ground and surrounds (umgreifen) FX from the outside.
Can realize a plurality of advantages with this layout.Because the braiding tool device clamps ground and surrounds FX from the outside, so people needn't enter agent structure again and arbitrarily fixing boring or other perforation that can weaken main body is set there.The braiding tool bar can be configured to continuous section or rather, and this continuous section has identical cross section and identical internal structure in its whole length.Therefore can make more simply.No longer include necessity and in main body, processing eye or threaded bore afterwards, therefore make and become simple, because omitted a few thing step, main body has surface of the same type in its whole length, thereby the post processing of braiding tool bar after manufacturing, for example to the grinding on its surface, be simplified.The installation of retaining element in main body also no longer is necessary during fabrication.The fixing of braiding tool device only realized by clamping.This has further advantage, that is, the braiding tool support can move and thereby be fixed in fact arbitrarily in the position along FX.This has greatly enlarged possibility when using the braiding tool bar.Because up to now, the Material reinforcement in FX in circumference no longer includes necessity, so realized favourable Mass Distribution.Can avoid in the position away from the pivotal axis that weaves tool bar larger quality being arranged.Produced more favorably moment of inertia.
The braiding tool device preferably surrounds seamed edge.Therefore weaving tool device can keep littlely.The braiding tool device only surrounds the less part of main body, that is the part of contiguous seamed edge.
The braiding tool device preferably has pedestal and clamping element, and clamping element is towards the direction of pedestal pretension flexibly.This has simplified installation.People can be thus pre-assembled braiding tool device to a certain extent, that is, will weave tool device and be clipped in and weave on the tool bar.
Use flexible pretension for this reason.This pretension can realize with different modes, for example compression or the extension by spring or the parts by the braiding tool device.Can implement orientation afterwards, and the risk that can not exist the braiding tool device to drop from sley bar.At last, clamping element can be loaded by tensioning apparatus, can produce greater than the prestressed tension force of spring between clamping element and pedestal with tensioning apparatus.When being used for making the flexible pretension that weaves tool bar work abundant not, can handle tensioning apparatus, with it the braiding tool device is fixed on the braiding tool bar like this, so that the braiding tool device can resist the power that occurs when the operation of braiding tool bar, and can not change its position on the braiding tool bar.
Clamping element preferably can not remain on the pedestal with losing.This has simplified installation.In fact the assembly crewman can will weave tool device with hand and be installed on the main body.
Preferably, tensioning apparatus has plug-in unit, and this plug-in unit inserts pedestal from a side, and wherein, clamping element is arranged on the opposite side of pedestal, and plug-in unit and clamping element pass pedestal and interconnect by securing member.Securing member for example can be a kind of screw bolt.The layout of passing through to paint, all can not remained on the braiding tool device at element required in order will to weave tool device and to be fixed on the sley bar time with losing.The assembly crewman must only be placed in the braiding instrument in the desired position that weaves on the tool bar, and directed there.When assembly crewman's operated fastener, the braiding instrument can be final afterwards, but can be fixed on the braiding tool bar with removing.
At this preferably, clamping element relatively plug-in unit pivot around jointed shaft.Clamping element and pedestal consist of a kind of pincers, can produce the required power of tensioning in simple mode with it.In addition, jointed shaft is used for parts can not tightened together with losing.
At this preferably, clamping element has the projection of giving prominence to with exceeding jointed shaft, and projection abuts on the pedestal.Can produce the power that can be used for the elasticity pretension by this projection.
FX preferably has the groove that is parallel to the seamed edge extension, and the part of braiding tool device is positioned in this groove.Although the main body of braiding tool bar does not have perforation, hole or eye, can produce a kind of form fit with this groove, form fit has further improved security when fixing braiding tool device.In addition, when people used the elasticity pretension of clamping element, this groove had been simplified installation.In this case, the braiding tool device is clipped on the main body of braiding tool bar thus simply, that is, with a part of kayser of clamping element in groove.In case this point has occured, danger that just there will be no the braiding tool device to come off from sley bar.The assembly crewman is then can be by easy stages directed, and does not need the immobilising device that adds etc.
At this preferably, groove has the sidewall with the seamed edge adjacency, and sidewall tilts.When the braiding tool device on the braiding tool bar during tensioning, this inclination just be used for making the braiding tool device perpendicular to the longitudinal extension of braiding instrument and perpendicular to the thickness direction of braiding tool bar move a preposition to.This be convenient to need not larger cost ground with all braiding instruments along identical arranged in a straight line.
At this preferably, the part of braiding tool device is that clamping element and clamping element have clamping area, and the gradient of clamping area and the gradient of sidewall match.When tensioning, to a certain extent, two chock mating reactions, chock is located in desired mode relative to each other by the descending power (Hangabtriebskraft) of tensile force and associated.
Main body preferably has locating slot, and the braiding tool device stretches into this locating slot.At this, the braiding tool device can have the inclined-plane, and the inclined-plane stretches in the locating slot.Locating slot can have with the inclined-plane matches and docks the inclined-plane.Therefore locating slot finishes two tasks.It defines the final position on the one hand, and the braiding tool device can be perpendicular to the longitudinal extension direction that weaves tool bar and mobile until this final position at the braiding tool bar perpendicular to the thickness direction of braiding tool bar.On the other hand, prevented that with the docking inclined-plane of inclined-plane mating reaction the main body of the relative sley bar of braiding tool device from tumbling.Locating slot will weave to a certain extent tool device and be fixed on the second place in the FX.
The braiding tool device preferably has the braiding tool support, and braiding instrument pedestal configurations becomes the plane symmetry of extending about being parallel to main body.In this case, can for example reuse a pin that has that has has worn and torn by upset braiding tool support.
Also advantageously, the braiding tool device has the acting surface that at least one is used for orientation tool.This has simplified the location that the braiding tool device weaves tool bar relatively.
Description of drawings
Next by preferred embodiment and be described with reference to the accompanying drawings the present invention.In the accompanying drawing:

Fig. 2 shows the cross section A-A by Fig. 1;
Fig. 3 is the amplification sectional view by the details C of Fig. 2;
Fig. 4 is a kind of alternative design scheme of relative Fig. 1;
Fig. 5 shows the section B-B by Fig. 4;
Fig. 6 is the stereogram of braiding tool support; And
Fig. 7 shows the braiding tool support by Fig. 6 from the side.
The specific embodiment
The braiding tool bar 1 that schematically shows in Fig. 1 is configured to yarn guiding chase comb under present case, and has main body 2, and main body has seamed edge 3.Braiding tool device 4 is fixed on the main body 2.For this reason, main body 2 has the FX with abutment face 5, and as shown in Figure 2, braiding tool device 4 can be contained on the abutment face.
Clamping element 11 has hinge protrusions 12, and hinge protrusions stretches into through hole 8.Plug-in unit 9 has hinge cover 13, thus clamping element 11 relatively plug-in unit 9 pivot around jointed shaft 14 with relative braiding tool support 7.
Clamping element 11 has in the side back to fastening bolt 10 and exceeds the projection 15 that jointed shaft 14 ground are given prominence to, and can contact with the braiding tool support in any case projection 15 abuts on the braiding tool support 7 or when clamping element 11 pivots around jointed shaft 14.
As shown in Figure 2, main body 2 has locating slot 21, bearing 7 usefulness two tops 22(Fig. 1) stretch into this locating slot.Top 22 has respectively an inclined-plane 23.Locating slot 21 has corresponding docking inclined-plane 24.When the braiding tool support 7 along arrow 25 when the abutment face 5 of main body moves, locating slot 21 is finished two tasks in conjunction with top 22.Locating slot has limited braiding tool support 7 along the moving of arrow 25 directions, and defines thus the final position on this direction.Then inclined-plane 23 and docking inclined-plane 24 cause, and the braiding tool support closely abuts on the abutment face 5.But inclined-plane 23 and docking inclined-plane 24 have prevented that at first braiding tool support 7 from leaving abutment face 5 and tumbling.
In order to install, fastening bolt is released, until relative braiding tool supports 7 elastic dilatations so far away of clamping element 11, thereby so that stop protrusion 18 can be crossed protuberance moves and enter groove 17.This position is shown in Figure 3.Because when expansion projection 15 contact with braiding tool support 7 and in the two at least one can slight elasticity be out of shape, so flexible expansion has occured.Even when the clamping force of setting up under this situation also is not enough in 1 operation of braiding tool bar, also braiding tool support 7 can be fixed tightly on the main body 2 safely, can not be clamped on the main body 2 but realized to weave tool device 4 with losing.The assembly crewman can vertically positioning braiding tool device 4 along main body 2.When arriving desired position, braiding tool device 4 is tensioned firmly by handling fastening bolt 10 thus, namely by fastening bolt 10 is rotated relative to clamping element 11.Under many circumstances, can lack than fastening bolt 10 is rotated also relative to clamping element 11 at this desired.
In this tensioning, clamping element 11 moves on the plug-in unit 9.At this, clamping area 20 slides at the sidewall 19 of the inclination of groove 17, thereby braiding tool support 7 is pulled and top 22 is moved into locating slot along arrow 25 directions.
In some cases, when the elasticity pretension between the tool support 7 at clamping element 11 and braiding can be otherwise, when realizing by fastening bolt 10 and plug-in unit 9, then can cancel the projection 15 on clamping element.
Fastening bolt 10 is located on the side of braiding tool bar 1, and the assembly crewman can get at this fastening bolt.Or rather, on this side, also carry warp thread.
Figure 4 and 5 show a kind of relatively by the form of implementation after the form of implementation modification of Fig. 1 to 3.The identical element identical with function marks with identical Reference numeral.
As seen from Figure 5, abutment face 5 is arranged on the opposite side of main body 2 now.Bolt 10 passes clamping element 11 and inserts and be screwed in the plug-in unit 9.Therefore the assembly crewman gets at fastening bolt 10 from a side identical with Fig. 1 to 3.
The advantage of this layout is that braiding tool support 7 deviates from this case the yarn direction 26 that is shown in broken lines and tilts.Two advantages have been produced thus.First is that yarn direction 26 can be more near the main body 2 that weaves tool bar 1.When use has a pin as braiding instrument 6, can with there being a pin to construct than all wanting up to now much shorter, therefore improve rigidity.
Fig. 6 shows a pin bearing 7 that has that does not clamp device.Can see that bearing 7 is configured to about in their front 27 and the plane symmetry between the back side 28.When having a pin to be worn, can reuse a pin that has that has has worn and torn by upset braiding tool support 7.
Establishing hollow-out parts in the zone 29 of braiding instrument 6, this hollow-out parts is used for reducing quality.This hollow-out parts can also be improved orientation in addition, because can create thus two limited tops 22, the top can enter locating slot 21.
In addition, as shown in Figure 7 about the symmetry on plane 30.
Can see that by Fig. 1 and 4 braiding tool support 7 has boring 31,32, the braiding tool support can be as the acting surface of orientation tool.
This braiding tool bar especially is fit to use the carbon fiber reinforced plastics.The main body 2 of braiding tool bar 1 can have in its whole length identical cross section and identical internal structure.Can not weaken main body 2 by boring etc.Also needn't establish insert during fabrication.Therefore make relatively simple.On the cross section of braiding tool bar 1, also realized favourable Mass Distribution.Because main body 2 can be not weakened by boring, need not to increase intensity and the rigidity that quality just can reach braiding tool bar 1.When main body 2 is hardened, after sclerosis, no longer need the post processing of doing to waste time and energy in mould.
Fixing comparatively simple on FX 16 of braiding tool support 7.Braiding tool device 4 at first is clipped on the FX 16 simply, then can be directed.After carrying out orientation, can carry out tensioning by fastening bolt 10.
