Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of pick-up unit, particularly a kind of pick-up unit that is used to detect crankshaft strength.
Background technology
Bent axle is the main rotary gadget of engine, load onto connecting rod after, can accept connecting rod about (back and forth) motion become circulation (rotation) and move.Bent axle is important parts on the engine, and its material is processed by structural carbon steel or spheroidal-graphite cast iron.
Bent axle is made up of keyway, gear axle journal, king journal, crank arm, rod journal, oil sealing platform, flywheel axle journal etc.Wherein the two ends of rod journal are connected on the crank arm, and connectivity robustness has determined the stability of bent axle between the two.
Bent axle need carry out multinomial detection to it after being fabricated to finished product, for example throw of crank shaft detection, the detection of crankshaft thrust face roughness etc.But, also do not have special-purpose device or instrument that it is detected for the detection of the connectivity robustness between rod journal and the crank arm.
Summary of the invention
The purpose of the utility model is the problems referred to above that exist to prior art, and a kind of crankshaft strength pick-up unit simple in structure, easy and simple to handle is provided.
The purpose of the utility model can realize through following technical proposal: a kind of pick-up unit of crankshaft strength, comprise a frame, and it is characterized in that; This device comprises power twister, holder, torsion torque sensor and shaft coupling; Holder is connected in frame one end and holder can be fixed bent axle one end, and power twister is connected in the frame other end, and an end and the shaft coupling of power twister link; The other end of shaft coupling can be fixed with the bent axle other end, and above-mentioned torsion torque sensor is positioned at the shaft coupling place.
Power twister detects it through torsion torque sensor the torsion that shaft coupling applies, and that is to say, the fixing torque value of output detects strength of crankshaft.Torque value improves constantly in the test process, when bent axle is destroyed this bent axle at this torque value during at a certain torque value, is strength degree.Whether the torque value when certainly, being destroyed according to it can be judged is specification product.
In the pick-up unit of above-mentioned a kind of crankshaft strength; The quantity of said shaft coupling is two: shaft coupling one and shaft coupling two; Above-mentioned shaft coupling one is connected in the torsion torque sensor both sides respectively with shaft coupling two; The other end and the power twister of said shaft coupling one link, and the other end of said shaft coupling two can link with the other end that is positioned at the bent axle on the holder.
Can find out that torsion torque sensor is arranged between two shaft couplings, make torsion torque sensor can accurately test its torque value like this.
In the pick-up unit of above-mentioned a kind of crankshaft strength; Described holder comprises air spider and anchor clamps; Air spider is used for bent axle middle part clamping, and anchor clamps are connected on other end of bent axle and the anchor clamps has two connecting links, and above-mentioned two connecting links and the shaft coupling other end link.
Because the bent axle middle part is held, so torsion torque sensor is through just making an end of bent axle receive twisting force in the connecting link drive anchor clamps rotation process.
In the pick-up unit of above-mentioned a kind of crankshaft strength, described air spider is a scroll chuck.
Can be through scroll chuck with bent axle firm the grasping in middle part.
In the pick-up unit of above-mentioned a kind of crankshaft strength, said torsion torque sensor place has the display screen that is used to show torque value.
Through display screen, the torque value of the understanding power twister output of operator's ability current events.
Compared with prior art, after this device grasps crank, can accomplish the detection operation through the power twister outputting torsion.Therefore, this device is easy and simple to handle.Simultaneously, can also in time understand torque value through display screen in the test process, applicability is higher, has higher utility.

Fig. 1 is the structural representation of the pick-up unit of this crankshaft strength.
Among the figure, 1, frame; 2, power twister; 3, air spider; 4, anchor clamps; 5, torsion torque sensor; 6, shaft coupling one; 7, display screen; 8, connecting link; 9, bent axle; 10, shaft coupling two.
Embodiment
As shown in Figure 1, the pick-up unit of this crankshaft strength comprises frame 1, power twister 2, holder, torsion torque sensor 5 and shaft coupling.
Holder is connected in frame 1 one ends and holder can be fixed bent axle 9 one ends.The quantity of shaft coupling is two: shaft coupling 1 and shaft coupling 2 10; Shaft coupling 1 is connected in torsion torque sensor 5 both sides respectively with shaft coupling 2 10; The other end of shaft coupling 1 and power twister 2 link, and the other end of shaft coupling 2 10 can link with the other end that is positioned at the bent axle 9 on the holder.In the present embodiment, torsion torque sensor 5 places have the display screen 7 that is used to show torque value.
Holder comprises air spider 3 and anchor clamps 4, and air spider 3 is used for bent axle 9 middle part clampings, and anchor clamps 4 are connected on bent axle 9 other ends and the anchor clamps 9 has two connecting links 8, and above-mentioned two connecting links 8 link with shaft coupling 2 10 other ends.In the present embodiment, air spider 3 is a scroll chuck.
The torsion that 2 pairs of shaft couplings of power twister apply detects it through torsion torque sensor 5, that is to say, the fixing torque value of output detects the intensity of bent axle 9.Torque value can be adjusted according to the actual requirements in the test process, when bent axle 9 is destroyed this bent axle 9 at this torque value during at a certain torque value, is strength degree.Certainly, also can judge whether bent axle 9 is specification product through this device.
