The detection device is characterized in that a square blind hole (3) is formed on the upper end of the torque sensor (2), and an adapter (4) adaptive to the shape of a spanner head is movably inserted in the blind hole; the thrust locating mechanism is a counterforce arm stopper (6) in which the position can be adjusted; and the digital display instrument (9) is internally provided with an electric signal digital processing system and a digital display panel. The detection device has a simple structure; the torque sensor and the adapter are conveniently and quickly inserted; the position of the counterforce arm stopper can be adjusted; the detection device is suitable for the torque detection of hydraulic torque spanners with different types and different shapes of spanner heads; and the digital display instrument can directly display the detected torque value.

Description

The hydraulic torque wrench pick-up unit

Technical field

The utility model belongs to pick-up unit, is specifically related to a kind of device that the moment of torsion of hydraulic torque wrench is detected.

Background technology

At present, the hydraulic torque wrench kind is a lot, and specification does not wait, but few at the instrument of the detection of hydraulic torque wrench and verification, and existing hydraulic torque wrench detector substantially all exists complex structure, damages and deficiency such as versatility difference easily.

The utility model content

The purpose of this utility model is to overcome deficiency of the prior art, proposes a kind of simple in structure, hydraulic torque wrench pick-up unit that versatility is good.

The technical scheme that realizes above-mentioned purpose is: a kind of hydraulic torque wrench pick-up unit, comprise the torque sensor that is fixed on the housing and thrust detent mechanism and the digital display instrument that is connected with sensor, it is characterized in that, there is a square blind hole upper end of described torque sensor, in this blind hole movable be plugged with one with the suitable adapter of driving end shape; Described thrust detent mechanism is an adjustable counter-force arm stop block in position; Electric signal digital processing system and digital display plate are installed in the described digital display instrument.

During detection, the hydraulic torque wrench head is connected with torque sensor by adapter, and the handle of spanner is contacted with counter-force arm stop block, give the reinforcing of hydraulic pressure dial torque wrench, the spanner occurred level is rotated by hydraulic pump.In this process, counter-force arm stop block stops that spanner rotates, and the moment of torsion of generation passes to torque sensor by adapter, and sensor deforms and will be out of shape the electric signal that is produced and outputs on the digital display instrument, and digital display instrument shows its torque value at once.

The utility model is simple in structure, and torque sensor and adapter are pegged graft convenient, fast, the counter-force arm stop block adjustable positions, and the moment of torsion that is fit to the hydraulic torque wrench of different model, difformity driving end detects, and digital display instrument can directly show the torque value of mensuration.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As Fig. 1 to shown in Figure 6, the utility model hydraulic spanner calibrating instrument mainly comprises housing 1, be fixed on the housing 1 torque sensor 2 and as the counter-force arm stop block 6 of thrust detent mechanism.The signal output part of torque sensor is connected with digital display instrument 9 through data line by the test interface 7 that is installed on the housing 1; There is a square blind hole 3 upper surface of torque sensor 2, and the hypomere of adapter 4 and square blind hole 3 are adaptive and peg graft wherein, the top of adapter 4 have one with the suitable spliced eye 5 of driving end shape; Counter-force arm stop block 6 is by being bolted on the housing 1, and its horizontal level can be adjusted.

Sensor 2 tops are fixed on the housing 1 by assembly parts such as back-up ring and bearings, and the below prevents that by on the base plate that is bolted to housing sensor 2 from rotating.

The spliced eye 5 on adapter 4 tops can be multiple shape, and for example square (as shown in Figure 6), regular hexagon or other regular polygons, the different shape difform driving end that is used to peg graft so both can guarantee that this device had versatility.

The inside of housing 1 is equipped with built-in power 8 (as shown in Figure 2), its effect is to torque sensor 2 power supplies, when deformation takes place in torque sensor 2, built-in power 8 is supplied with these sensor 2 original magnitudes of voltage and will be changed, test interface 7 is passed to digital display instrument 9 with the voltage signal that changes, and digital display instrument is through demonstrating the torque value of tested hydraulic spanner after the data processing.

Claims

1. hydraulic torque wrench pick-up unit, the digital display instrument (9) that comprises housing (1), is fixed on torque sensor (2) and the thrust detent mechanism on the housing and is connected with sensor, it is characterized in that: there is a square blind hole (3) upper end of described torque sensor (2), in this blind hole movable be plugged with one with the suitable adapter (4) of driving end shape; Described thrust detent mechanism is an adjustable counter-force arm stop block in position (6); Electric signal digital processing system and digital display plate are installed in the described digital display instrument (9).

2. according to the described pick-up unit of claim 1, it is characterized in that: the spliced eye (5) on described adapter (4) top is square, regular hexagon or other regular polygons.
