Abstract

The utility model discloses a detector for jerk value of gear rack meshing, being characterized in that the detector clamps a rack by using a positioning clamp workpiece; a limit device fixes one end of the rack; a torque sensor is arranged on an input axis of a gear; a displacement sensor is arranged on the other end of the rack; and the displacement sensor and the torque sensor respectively access a signal processor. Due to the above structure, the detector for jerk value of gear rack meshing has the advantages that 1, the jerk value of the gear rack meshing can be accurately detected; 2, the detecting data can be displayed real-timely; and 3, the influence of the impact force can be avoided by manually applying the torque force uniformly, thus having high detection accuracy.

Description

A kind of pick-up unit of rack-and-pinion engagement jerk value

Relate to the field

The utility model relates to a kind of pick-up unit of rack-and-pinion engagement jerk value.

Background technology

Various plant equipment are all used the engagement of rack-and-pinion, and more and more important for the detection of rack-and-pinion engagement jerk value, this is the key that guarantees equipment quality.The jerk value of rack-and-pinion engagement at present mainly is that employing equipment applies certain torsion at an end of gear input shaft end or tooth bar; Detect with dial gauge at the tooth bar other end; The back is by the number of beating of manual record dial gauge, and this number of beating is exactly the jerk value of rack-and-pinion engagement.

Measure not only inefficiency like this, labour intensity is big, and owing to receive the restriction of testing conditions, for example the torsion of equipment input has certain impulsive force etc., detected result is inaccurate.

A kind of novel pick-up unit is provided, and it is the problem that prior art need solve that rack-and-pinion engagement jerk value is accurately measured.

The utility model content

The utility model technical matters to be solved is that the pick-up unit that provides a kind of rack-and-pinion to mesh jerk value has reached the purpose that rack-and-pinion engagement jerk value is accurately measured.

For solving the problems of the technologies described above; The technical scheme of the utility model is; A kind of pick-up unit of rack-and-pinion engagement jerk value, it is characterized in that: described pick-up unit is clamped tooth bar for the locating clip clamping of workpieces, an end of stop means stationary rack; Torsion torque sensor is installed on the input shaft of gear, and displacement transducer is installed in the other end of tooth bar; Displacement transducer, torsion torque sensor insert signal processor respectively, thereby utilize signal processor to realize rack-and-pinion engagement jerk value is accurately measured.

Described displacement transducer, torsion torque sensor insert signal processor through signal amplifier respectively.

Described signal processor passes to the jerk value that calculates on the equipment display screen, makes measurement data shown in real time.

Described torsion torque sensor is provided with spanner, and the manual torsion that evenly applies of utilization is avoided owing to impulsive force influences the accurate of test.

A kind of pick-up unit of rack-and-pinion engagement jerk value, owing to adopt said structure, this pick-up unit has the following advantages: 1, the jerk value of rack-and-pinion engagement is accurately measured; 2, test data can show in real time; 3, utilize the manual influence that torsion is avoided impulsive force that evenly applies, measuring accuracy is high.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation;

Fig. 1 is the structural representation of the pick-up unit of a kind of rack-and-pinion engagement of the utility model jerk value;

Fig. 2 is that the A of pick-up unit of a kind of rack-and-pinion of the utility model engagement jerk value is to cross-sectional view;

In Fig. 1-2,1, displacement transducer; 2, spanner; 3, torsion torque sensor; 4, locating clip clamping of workpieces; 5, stop means.

Embodiment

The utility model purpose is to change existing metering system, improves existing testing conditions, improves the accuracy rate that rack-and-pinion engagement jerk value detects.

As shown in Figure 1, the utility model is that locating clip clamping of workpieces 4 is clamped tooth bar, and an end of stop means 5 stationary racks, torsion torque sensor 3 are installed on the input shaft of gear, and displacement transducer 1 is installed in the other end of tooth bar; Displacement transducer 1, torsion torque sensor 3 insert signal processor through signal amplifier respectively, thereby utilize signal processor to realize rack-and-pinion engagement jerk value is accurately measured.Signal processor passes to the jerk value that calculates on the equipment display screen, makes measurement data shown in real time.

Torsion torque sensor 3 is provided with spanner 2, and the manual torsion that evenly applies of utilization is avoided owing to impulsive force influences the accurate of test.

The utility model is separated and is utilized locating clip clamping of workpieces 4; With stop means 5 stationary racks one end; Use the spanner 2 of subsidiary torsion torque sensor 3 at the uniform velocity afterburning at input shaft end by manual work; Use displacement transducer 1 to lean against the jerk value that the tooth bar other end detects tooth bar, torsion torque sensor 3 is connected with the device signal processor through signal amplifier with displacement transducer 1, on the equipment display screen, shows the curve of torsion and displacement when reinforcing detects jerk value; On this curve, get the pairing shift value of certain torsion, this numerical value is exactly the jerk value of rack-and-pinion engagement.Equipment is gathered this value automatically and is transferred to the total data storehouse through network simultaneously.

Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as the various improvement of having adopted the utility model technical scheme to carry out; Or directly apply to other occasion without improvement, all within the protection domain of the utility model.
