A kind of brake ribbon assembly tooling
Technical field
The utility model relates to a kind of brake ribbon assembly tooling.
Background technology
The wide model of band brake is applied to manual, hydraulic brake system fields such as deck machinery.Mainly be to be loaded on the brake steel band with no asbestos brake ribbon, with the counterbore screw both compressed then.Require brake steel band and brake ribbon to fit tightly, do not have the gap substantially.
Assembler people is being perplexed in the assembling of brake ribbon and steel band always, does not form because brake ribbon has the asbestos fabric by copper wire, and certain degree of hardness and intensity are arranged, and brake ribbon and steel band are difficult to accomplish to fit tightly.At present the common process method is with a plurality of agrafes both to be clipped together, and with the counterbore screw both is compressed then, and then is assembled to that deck machinery etc. is manual, water brake equipment gets on.But adopt the band brake of this method assembling, the fit clearance of brake ribbon and steel band still has the 0.5-1mm gap, can not meet the demands.Excesssive gap between the two can cause brake ribbon and brake hub loose contact, the wearing and tearing of brake ribbon local excessive; Also there is the risk that is sheared fracture in housing screw, then can cause brake system to lose efficacy if the screw shear fracture occurs, brings serious security incident for equipment such as boats and ships, locomotive.
Summary of the invention

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail: see Fig. 1, a kind of band brake 1, what comprise steel band 10 and be arranged on steel band 10 sides does not have the brake ribbon 12 that the asbestos fabric is formed by copper wire.During use, need be with bolt with brake ribbon 12 being fitted on the steel band 10 tightly.Traditional assembling mode is to offer bolt hole after with agrafe both being clipped together, twist then and establish bolt and make both combinations, be understandable that, but adopt this mode of agrafe, have only the stressed place of agrafe to fit tightly, all the other are local owing to do not have strongly to be clamped on steel band 10 and the brake ribbon 12, so inevitably both the gap will occur.
Main purpose of the present utility model is reliably with brake ribbon 12 being fitted on the steel band 10 tightly.Avoid both the gap to occur.
A kind of brake ribbon assembly tooling, comprise workbench 3, described workbench 3 is provided with for the fixture 5 that steel band 10 is fastened on the workbench 3, and described workbench 3 is provided with for promoting brake ribbon 12 slippages and preventing the drive unit 7 of brake ribbon 12 resiliences corresponding to the end of band brake brake ribbon 12.In the utility model, described fixture 5 is provided with 2, and one of them fixture 5 is positioned at 2/3rds positions of steel band 10, another fixture 5 is positioned at 9/10ths positions of steel band 10, when fixture 5 is fastened at workbench 3 with steel band 10 like this, the acquisition balance of can exerting all one's strength, thus brake ribbon 12 is fitted on the steel band 10 more closely.
Described fixture 5 comprises the chute 30 that is arranged on workbench 3 upper surfaces, the inside narrow contracting in the upper end of described chute 30 is embedded with slide block 53 in the described chute 30, because the narrow contracting in upper end of chute 30, make this slide block 53 still can not move up and down along slippage in chute 30.
The top of described slide block 53 is provided with first bolt 51, one pressing plate 50 is set on this first bolt 51, the upper end of described first bolt 51 is twisted and is provided with nut 52, described pressing plate 50 belows also are provided with bracing or strutting arrangement 54 described bracing or strutting arrangements 54 and comprise cushion block 541, and the top of described cushion block 541 is twisted and is provided with second bolt 542.Be provided with bracing or strutting arrangement, steel band 10 is flushed with bracing or strutting arrangement, thereby make pressing plate 50 obtain dynamic balance, clamp steel band 10 thereby more utilize.And the bracing or strutting arrangement adjustable height, like this pressing plate 50 under normal condition, substantially horizontal.Steel band 10 is clamped reliably.
Described drive unit 7 comprises the fixed head 70 that is fixed on the workbench 3, twists on the described fixed head 70 and is provided with the 3rd bolt 73, and the end that described brake ribbon 12 ends are provided with baffle plate 72, the three bolts 73 leans on the sidewall of baffle plate 72.
The method of brake ribbon assembling comprises the steps: 1) offer some through holes at steel band 10 sidewalls in advance; 2) turn first bolt 51, make pressing plate 50 1 side pressures on bracing or strutting arrangement 54, opposite side is pressed on the steel band 10, and steel band 10 vertically is fixed on the workbench 3; 3) with brass bolt one end of steel band 10 and brake ribbon 12 is fixed,, and make brake ribbon 12 in the length of length greater than steel band 10; Because the relative plain bolt toughness of brass bolt is stronger, adopting the effect of brass bolt is to prevent brake ribbon 12 pressure breaks.
4) steel band 10 and brake ribbon 12 are fit together; 5) end of the pressing plate 50 promotion brake ribbons 12 of rotation the 3rd bolt 73, the three bolts 73 ends makes brake ribbon 12 be close to steel band 10.And promote the end of brake ribbon 12 and the end of steel band 10 always and flush, finally make brake ribbon 12 and steel band 10 as shown in Figure 1.When rotating the 3rd bolt 73, can also beat the sidewall of brake ribbon 12 with wooden mallet, beat in the process of wooden mallet, can make brake ribbon 12 itself exist male and fomale(M﹠F) to improve.Also further make brake ribbon 12 be close to steel band 10.In addition, beat wooden mallet and also can make brake ribbon 12 press to steel band 10 always, prevent by brake ribbon 12 perks.
6) pass brake ribbon 12 with brass bolt and be located in the through hole, the end of brass bolt is twisted and is provided with nut, and brake ribbon 12 and steel band 10 are fit together closely.
The utility model is owing to the length of brake ribbon 12 length greater than steel band 10, under the forceful action of baffle plate 72, unnecessary brake ribbon 12 can be compressed on the steel band 10, also be that brake ribbon 12 can be by abutting on the steel band 10 tightly, also be brake ribbon 12 and steel band 10 arbitrary positions all fit very tight, the part situation closely of not fitting can not appear.Therefore brake ribbon 12 and steel band 10 gaps have effectively been avoided.In addition, owing in the assembling process, only need to rotate the 3rd bolt, just can make the brake ribbon 12 can be by abutting on the steel band 10 tightly, so greatly reduce installation time, improve production efficiency greatly.
