Abstract
The utility model provides a device for detecting mechanical property of a clock spring, and an objective is to accurately detect the mechanical property of the clock spring. The device comprises a drive plate, a clock spring inner ring, a base, a positioning tool, a work bench, a torque sensor, a hexagonal prism shaft, and a motor. The motor is fixed with the hexagonal prism shaft through socket head cap screws. The drive plate is provided with a hexagon hole matched with the hexagonal prism shaft. The positioning tool is disposed in the base. The base positioning tool is a duralumin block which is chamfered according to the shape of the base, and the base positioning tool is fixed on the torque sensor through four struts.
Description
Technical field
The utility model relates to a kind of equipment that detects the clock spring mechanical property.
Background technology
Clock spring is used for air bag system, requires performance reliably, so the Performance Detection of clock spring is extremely important, directly to affect the reliability of air bag.The mechanical property of clock spring detected in the past just manual sensation rotating torque, and it also is by people's number that the number of turns detects, last centering.Quality can't guarantee that in case artificial carelessness, the centering number of turns is not right, will cause clock spring not turn enough enough number of turns with bearing circle, causes clock spring inside impaired.
Summary of the invention
The utility model purpose is the deficiency that overcomes above-mentioned prior art, provides a kind of and can accurately detect the mechanical property of clock spring and the clock spring mechanical property checkout equipment of automatic centering.
The utility model comprises driver plate, clock spring inner ring, base and positioning tool, worktable, torque sensor, hexagonal prism axle, motor.Be fixed with the hexagonal prism axle by socket head cap screw on the motor shaft, driver plate is provided with the hexagonal hole that cooperates with the hexagonal prism axle, and electric machine rotation drives the hexagonal prism axle and driver plate rotates, and rotates thereby drive the clock spring inner ring.The base positioning tool is the duralumin piece of pressing the grooving of base shape, and positioning tool is put into base, makes the base can not axial-rotation, and the base positioning tool is fixed on the torque sensor by four pillars.Rotated by PLC control driven by motor hexagonal prism axle, when the hexagonal prism axle drives the rotation of clock spring inner ring together with driver plate, clock spring rotates and produces moment, then this moment makes the clock spring base produce the rotation of certain angle, the base gyration, because it is fixed on the torque sensor, torque sensor is the certain moment of corresponding generation then, torque sensor changes into electric signal with this moment and is reacted among the PLC, and system compares through the corresponding torque limit of changing and presetting and judges whether part is qualified.In the number of turns of setting, moment of torsion does not exceed standard, and thinks that then the number of turns is qualified, and system realizes workpiece centering by PLC control motor.Moment of torsion exceeds standard, and then thinks defective, and system alarm quits work.
The utility model can solve the simple manual inspection number of turns centering of tradition, improving product detecting reliability, the effective ways of reduction workman's labour intensity.The mechanical property checkout equipment carries out torque measurement with accurate sensor, and maximal value must not surpass 15Ncm, system and automatically gather peak torque, and the number of turns is by setting value inspection, satisfactory then centralized positioning.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, driver plate; 2, clock spring inner ring; 3, positioning tool; 4, worktable, 5, torque sensor; 6, hexagonal prism axle; 7, motor.
Embodiment
The socket head cap screw of hexagonal prism axle 6 usefulness M3 is fixed on motor 7 axles, when motor 7 rotates, drives hexagonal prism axle 6 and driver plate 1 rotation, rotates thereby drive clock spring inner ring 2.Pass worktable 4 for the driver plate 1 of stirring the clock spring inner ring and be connected to following motor 7 axles, four M5 screws of positioning tool 3 usefulness are fixed on the torque sensor by four pillars.PLC control motor 7 rotates, driving clock spring inner ring 2 together with driver plate 1 rotates, clock spring rotates and produces moment, then this moment makes the clock spring base produce the rotation of certain angle, the base gyration, because it is fixed on the torque sensor 5,5 certain moments of corresponding generation of torque sensor, torque sensor 5 changes into electric signal with this moment and is reacted among the PLC, and system compares through the corresponding torque limit of changing and presetting and judges whether part is qualified.In the number of turns of setting, moment of torsion does not exceed standard, and thinks that then the number of turns is qualified, and system realizes workpiece centering by PLC control motor.Moment of torsion exceeds standard, and then thinks defective, and system alarm quits work.
