Description

Based on the connecting rod screw stretching-machine for determining moment of torsion slow-speed of revolution electric wrench
Technical field
Machine power transformation, control and detection means are the utility model is related to, more particularly to one kind is based on determining low turn of moment of torsion The connecting rod screw stretching-machine of fast electric wrench.
Background technology
Connecting rod screw is diesel locomotive connecting rod assembling vital part, in order to ensure that pretightning force is stable, it is desirable to which screw, which has, to be filled Divide reliable elastic performance, require to carry out pre-stretching experiment before assembly for this, to confirm to reach 0.66 ± 0.02mm of amount of tension After can recoil to initial length completely.Tension test is the first procedure in the assembling of diesel locomotive connecting rod.Existing hinge connects Direct type stretching-machine and hidrodynamic form stretching-machine are manufactured and designed by specialized factory, and cost is high, and it is inconvenient to safeguard, is only applicable to large-scale Locomotive works' internal combustion engine workshop uses, and is not easy to the small-sized assembling in Along Railway Locomotive Overhaul workshop and uses.
Utility model content
The purpose of this utility model is that to solve the above problems and provided a kind of electronic based on the moment of torsion slow-speed of revolution is determined The connecting rod screw stretching-machine of spanner.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model includes supporting mechanism, determines moment of torsion slow-speed of revolution electric wrench, handgrip, box spanner, connecting rod screw, drawing Stretch set, dial framework and measurement table, it is described to determine moment of torsion slow-speed of revolution electric wrench and be fixed on the supporting mechanism, it is described to determine low turn of moment of torsion The output shaft of fast electric wrench is connected with one end of the handgrip, and the other end of the handgrip is connected with the box spanner, institute State box spanner to be connected with the connecting rod screw, for the connecting rod screw positioned at stating in expanding sleeve, the dial framework is arranged at the drawing The end of set is stretched, the measurement table is located on the dial framework, the measurement end of the measurement table and the other end of the connecting rod screw Connection.
Further, pass through between the handgrip and the output shaft and box spanner for determining moment of torsion slow-speed of revolution electric wrench Cylinder pin connection.
The beneficial effects of the utility model are:
The utility model is a kind of based on the connecting rod screw stretching-machine for determining moment of torsion slow-speed of revolution electric wrench, with prior art phase Than the utility model can be widely used in railway locomotive depot repairing I. C. locomotive workshop, also suitable for diesel locomotive connecting rod spiral shell Accessory workshop is followed closely, it is not only cost-effective, and can controllably ensure that connecting rod screw is pre-stretched quality, control accuracy and detection Precision is high, can control error within 3%, fully meets 6% error of Element Design permission.Data herein are based on drawing The amount of stretching design load is 0.66 ± 0.02mm, and centimeter check device precision is 0.01mm, beneficial to popularization and is promoted.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure:1- supporting mechanisms, 2- determine moment of torsion slow-speed of revolution electric wrench, 3- handgrips, 4- box spanners, 5- connecting rod screws, 6- expanding sleeves, 7- dial frameworks, 8- measurement tables.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1:The utility model includes supporting mechanism 1, determines moment of torsion slow-speed of revolution electric wrench 2, handgrip 3, sleeve barrel spanner Hand 4, connecting rod screw 5, expanding sleeve 6, dial framework 7 and measurement table 8, it is described to determine moment of torsion slow-speed of revolution electric wrench 2 and be fixed on the support In mechanism 1, the output shaft for determining moment of torsion slow-speed of revolution electric wrench 2 is connected with one end of the handgrip 3, the handgrip 3 it is another One end is connected with the box spanner 4, and the box spanner 4 is connected with the connecting rod screw 5, and the connecting rod screw 5, which is located at, to be stated In expanding sleeve 6, the dial framework 7 is arranged at the end of the expanding sleeve 6, and the measurement table 8 is located on the dial framework 7, the survey The measurement end of scale 8 is connected with the other end of the connecting rod screw 5.
Further, between the handgrip 3 and the output shaft and box spanner 4 for determining moment of torsion slow-speed of revolution electric wrench 2 Pass through cylinder pin connection.
The course of work and operation principle of the present utility model are that operating personnel's installing connecting rods screw 5 allows into expanding sleeve 6 The measurement end of measurement table 8 withstands on the tail end face of connecting rod screw 5, and connecting rod screw 5 is adjusted to zero afterwards.The starting torque slow-speed of revolution is electronic Connecting rod screw 5 is tightened in spanner 2, the slow-speed of revolution, observes measurement table 8, to be tensioned to after desired length, reversion, unloads connecting rod screw 5, and whether measurement connecting rod screw 5 recovers to deform again, illustrates that the connecting rod screw 5 is qualified if recovering, it is on the contrary then unqualified, from And complete the tension test of connecting rod screw 5.
It is PID-LP-2000 to determine moment of torsion slow-speed of revolution electric wrench model.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model Claimed scope is by appended claims and its equivalent thereof.
