Each connecting sleeve comprises a column body, and two ends in the center of the column body are respectively provided with a ridge hole corresponding to the torsion wrench standard block and ridge holes corresponding to ridge columns on the two ears of the flyweight support. By the adoption of a pair of connecting sleeves, according to one tightening movement, the two ears are enabled to simultaneously reach a preset tightening value, the movement of operation is simple and rapid, the working efficiency is greatly improved, the phenomenon that one ear is not screwed up does not occur, and the quality of assembly is effectively guaranteed.
Description
Technical field
The present invention relates to the technical field of diesel engine part assembling, particularly relate to a kind of flying hammer bracket two ear with torsion method and adapter sleeve thereof.
Background technology
A kind of flying hammer bracket in high-pressure fuel pump of diesel engine, its symmetrical both sides are respectively by the rod member (also referred to as ear) that is threaded, and two ears will reach after screwing in screw corresponding to flying hammer brackets and given screw torsion.
If tighten two ears respectively to setting torque value by torque spanner, there is following defect: one inefficiency; It two there will be the situation that wherein an otorrhea is tight.
Summary of the invention
The object of the present invention is to provide a kind of by once tightening action, can screw two ears simultaneously and ensure that a kind of flying hammer bracket two ear of two ears with torsion is with torsion method and adapter sleeve thereof, its concrete technical scheme is as follows:
Described method is: adopt two adapter sleeves, to wherein be fixed on work top by an adapter sleeve, form a fixed connection cover, then be plugged in fixed operating sleeve by an ear of flying hammer bracket, make the relative fixed operating sleeve of flying hammer bracket without locating rotationally, again another adapter sleeve is plugged in another ear of flying hammer bracket, formed and be flexibly connected cover, with two ends grafting flexible connection cover and the torque spanner respectively of a torque spanner calibrated bolck, make three without relatively rotating connection, rotate torque spanner to preset value, two ears are tightened with same torsion.
The feature of described method is, described work top is arranged a prism, and described adapter sleeve is provided with the rib hole corresponding with described prism, and adapter sleeve is coordinated by rib hole and prism, and adapter sleeve is fixed on work top.
The feature of described method is, described prism is the prism identical with described torque spanner calibrated bolck.
Described adapter sleeve, comprises a cylinder, and the two ends at this cylinder center are respectively equipped with the rib hole corresponding with the calibrated bolck of torque spanner and the rib hole corresponding with prism on flying hammer bracket two ear.
It is characterized in that of described adapter sleeve, described cylinder center is provided with through hole, is circular hole in the middle part of this through hole, and this circular hole is communicated with the rib hole at two ends respectively.
It is characterized in that of described adapter sleeve, described cylinder is cylinder.
It is characterized in that of described adapter sleeve, described rib hole is the four rib holes corresponding with described prism and calibrated bolck
Beneficial effect of the present invention is: the present invention adopts a pair adapter sleeve, and by once tightening action, what make two ears reach setting tightens value simultaneously, becomes to tighten for twice to be operating as once-through operation, and make operational motion simple and fast, operating efficiency improves greatly; Because two ears are screwed simultaneously, there will not be the phenomenon that an ear is not tightened, assembly quality is effectively ensured.
Accompanying drawing explanation
Fig. 1 is flying hammer bracket and two ear Workpiece structure schematic diagrames.
Fig. 2 is that flying hammer bracket two ear of the present invention forms schematic diagram with torsion method.
Fig. 3 is connecting jacket structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Figure 1 shows that the assembly relation of flying hammer bracket and two ears, flying hammer bracket 2 both sides are the rod member (also referred to as ear) be threaded respectively, and flying hammer bracket one ear 1 and another ear 3 of flying hammer bracket also need to reach given torsion after screwing in the screw arrival tightened position of flying hammer bracket 2 and screw.Flying hammer bracket two ear of the present invention is be fixed on work top 5 by a wherein adapter sleeve 4 with the method that torsion screws, form a fixed connection cover, then an ear 1 prism end of flying hammer bracket is plugged in fixed operating sleeve 4, make the relative fixed operating sleeve 4 of flying hammer bracket 2 without locating rotationally, again another adapter sleeve 6 is plugged in the prism end of another ear 3 of flying hammer bracket, formed and be flexibly connected cover 6, with two ends grafting flexible connection cover 6 and the torque spanner 7 respectively of the torque spanner calibrated bolck 8 of a quadrangular shape, make three without relatively rotating connection, rotate torque spanner 7 to the torque value preset, two ears are tightened with same torsion.
Contrast Fig. 2, in the method that above-mentioned flying hammer bracket two ear of execution screws with torsion, work top 5 is arranged a prism 9, this prism 9 is the four prism type identical with calibrated bolck 8.Fixed operating sleeve 4 one end is provided with the rib hole corresponding with prism 9, is coordinated with prism 9 by this rib hole, and adapter sleeve 4 is fixed on work top 5.Fixed operating sleeve 4 other end is provided with the rib hole corresponding with prism on flying hammer bracket one ear 3, for flying hammer bracket one ear without being connected in relative rotation.
Please refer to Fig. 2 again, the rib hole, one end being flexibly connected cover 6 is the rib hole corresponding with torque spanner calibrated bolck 8, is flexibly connected cover 6 and is coordinated with the calibrated bolck 8 of a four prism type by this rib hole, thus realizes being connected without relative rotation with torque spanner.The other end being flexibly connected cover 6 is provided with the rib hole corresponding with prism on flying hammer bracket one ear, and this rib hole is for being connected without relatively rotating with another ear on flying hammer bracket equally.Can find out thus, the fixed operating sleeve 4 of the present embodiment is identical with the structure being flexibly connected cover 6.
Contrast Fig. 3, the body of the adapter sleeve 4,6 in above-described embodiment is a cylinder, and its center is provided with through hole, is circular hole in the middle part of this through hole, and this circular hole is communicated with the four rib rib holes at two ends respectively.
When adopting 4, the 6 pairs of flying hammer bracket two ears executions of above-mentioned adapter sleeve to screw with torsion, first the torque value of torque spanner 7 is adjusted to given torsion numerical value, pull torque spanner 7 when arriving set-point numerical value, by standard connector blocks 8, be flexibly connected cover 6, another ear 3 of flying hammer bracket one ear 1, flying hammer bracket 2, flying hammer bracket, with power realizes transmission and the balance of torsion between the prism 9 on fixed operating sleeve 4 and work top 5, make the installation lashing force of two ears of flying hammer bracket 2 all reach specified value simultaneously.
