Abstract
The invention relates to a simultaneous torsion method for two ears of a flyweight support and connecting sleeves for the same. The simultaneous torsion method comprises the following steps that two connecting sleeves are adopted, one of the connecting sleeves is fixedly arranged on a working platform to form a fixed connecting sleeve, one ear of the flyweight support is embedded into the fixed connecting sleeve to enable the flyweight support to be positioned without rotation relative to the fixed connecting sleeve, then the other connecting sleeve is embedded into the other ear of the flyweight support to form a movable connecting sleeve, a torsion wrench standard block is used for connecting the connecting sleeves and a torsion wrench in a relative zero-rotation manner, the torsion wrench is revolved to a preset value, and the two ears are screwed up with same torsion. 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, relate in particular to a kind of flying hammer bracket two ears with torsion method and adapter sleeve thereof.
Background technology
A kind of flying hammer bracket in the high-pressure fuel pump of diesel engine, its symmetrical both sides are threaded connection respectively a rod member (being also referred to as ear), and two ears will reach the given torsion that screws after screwing in screw corresponding to flying hammer bracket.
If tighten respectively two ears to setting torque value by torque spanner, have following defective: the one inefficiency; The wherein tight situation of an otorrhea appears in its two meeting.
Summary of the invention
The object of the present invention is to provide a kind of by once tightening action, can screw simultaneously two ears and guarantee two ears with a kind of flying hammer bracket two ears of torsion with torsion method and adapter sleeve thereof, its concrete technical scheme is as follows:
Described method is: adopt two adapter sleeves, wherein an adapter sleeve is fixed on the work top, cover forms a fixed connection, then with being plugged in the fixed operating sleeve an of ear of flying hammer bracket, make the relative fixed operating sleeve of flying hammer bracket without location rotationally, again another adapter sleeve is plugged in another ear of flying hammer bracket, form and be flexibly connected cover, relatively without connecting rotationally adapter sleeve and torque spanner, rotate torque spanner to preset value with a torque spanner calibrated bolck, two ears are tightened with same torsion.
Described method is characterised in that, a prism is set on the described work top, and described adapter sleeve is provided with the rib hole corresponding with described prism, and adapter sleeve is fixed on the work top adapter sleeve by rib hole and prismatic cooperating.
Described method is characterised in that described prism is the prism identical with described torque spanner calibrated bolck.
Described adapter sleeve comprises a cylinder, the two ends at this cylinder center be respectively equipped with the rib hole corresponding with the calibrated bolck of torque spanner and with flying hammer bracket two ears on prismatic corresponding rib hole.
It is characterized in that of described adapter sleeve, described cylinder center is provided with through hole, and this through hole middle part is circular hole, and this circular hole is communicated with respectively the rib hole at two ends.
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 of adapter sleeve, by once tightening action, makes two ears reach simultaneously the value of tightening of setting, and becomes to tighten for twice to be operating as once-through operation, makes the operational motion simple and fast, and operating efficiency improves greatly; Because two ears are screwed simultaneously, the phenomenon that an ear is not tightened can not occur, assembly quality is effectively guaranteed.
Description of drawings
Fig. 1 is flying hammer bracket and two ear Workpiece structure schematic diagrames.
Fig. 2 is that flying hammer bracket two ears of the present invention consist of schematic diagram with the torsion method.
Fig. 3 is connecting jacket structure schematic diagram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Figure 1 shows that the assembly relation of flying hammer bracket and two ears, flying hammer bracket 2 both sides are respectively the rod members (being also referred to as ear) that is threaded, and the screw arrival of another ear 3 screw-in flying hammer brackets 2 of flying hammer bracket one ear 1 and flying hammer bracket screws the torsion that also needs to reach given behind the position and screws.The method that flying hammer bracket two ears of the present invention screw with torsion is that an adapter sleeve 4 wherein is fixed on the work top 5, cover forms a fixed connection, then an ear 1 prismatic end with flying hammer bracket is plugged in the fixed operating sleeve 4, make flying hammer bracket 2 relative fixed operating sleeves 4 without locating rotationally, again another adapter sleeve 6 is plugged in the prism end of another ear 3 of flying hammer bracket, form and be flexibly connected cover 6, peg graft respectively with the two ends of the torque spanner calibrated bolck 8 of a quadrangular shape and to be flexibly connected cover 6 and torque spanner 7, make the three without relatively rotating connection, rotate torque spanner 7 to default torque value, two ears are tightened with same torsion.
Contrast Fig. 2 in implementing the method that above-mentioned flying hammer bracket two ears screw with torsion, arranges a prism 9 on the work top 5, this prism 9 is the four prism type identical with calibrated bolck 8.Fixed operating sleeve 4 one ends are provided with the rib hole corresponding with prismatic 9, cooperate with prismatic 9 by this rib hole, and adapter sleeve 4 is fixed on the work top 5.Fixed operating sleeve 4 other ends are provided with the rib hole corresponding with prism on flying hammer bracket one ear 3, are used for flying hammer bracket one ear without being connected in relative rotation.
Please refer to Fig. 2, an end rib hole that is flexibly connected cover 6 is the rib hole corresponding with torque spanner calibrated bolck 8 again, be flexibly connected cover 6 and cooperate with the calibrated bolck 8 of a four prism type by this rib hole, thereby realization and torque spanner without being connected with relatively rotating.The other end that is flexibly connected cover 6 be provided with flying hammer bracket one ear on prismatic corresponding rib hole, equally this rib hole be used for flying hammer bracket on another ear be connected without relatively rotating.Can find out that thus the structure of the fixed operating sleeve 4 of present embodiment and flexible connection cover 6 is identical.
Contrast Fig. 3, the adapter sleeve 4 in above-described embodiment, 6 body are a cylinder, and the cylinder center is provided with through hole, and this through hole middle part is circular hole, and this circular hole is communicated with respectively the four rib rib holes at two ends.
When adopting above-mentioned adapter sleeve 4,6 pairs of flying hammer bracket two ears to implement to screw with torsion, at first the torque value of torque spanner 7 is adjusted to given torsion numerical value, when pulling torque spanner 7 and arriving set-point numerical value, by standard contiguous block 8, be flexibly connected cover 6, flying hammer bracket one ear 1, flying hammer bracket 2, another ear 3 of flying hammer bracket, and power realizes transmission and the balance of torsion making the installation lashing force of two ears of flying hammer bracket 2 all reach specified value simultaneously between the prism 9 on fixed operating sleeve 4 and the work top 5.
