Description
Technical field
The utility model relates to a kind of nozzle concentricity and detects tool.
Background technology
At present, the anterior diametric size concentricity requirement higher (in the 0.01mm) of flange and nozzle when detecting size with this, must be put on the three-dimensional measurement bed and measure, and not only efficient is low but also amount bed mobility is low.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of nozzle concentricity to detect tool, and this tool is not only simple in structure, and efficient is high.
The utility model for the technical scheme that solves its technical matters and adopt is: a kind of nozzle concentricity detects tool; Comprise substrate, pillar plate, hoodle adjustable plate, Workpiece carrier plate, location-plate, hoodle and hold-down mechanism; Said pillar plate is two, and is fixedly arranged on said substrate top at interval; Said Workpiece carrier plate is fixedly arranged on said two blocks of pillar plates top; Said hoodle adjustable plate is fixedly arranged on said Workpiece carrier plate top one side, and said location-plate is fixedly arranged on the opposite side of said Workpiece carrier plate top; Said location-plate is provided with a v-notch at least near said hoodle adjustable plate one end, on said hoodle adjustable plate, be provided with just over against said v-notch place can ccontaining said hoodle through hole, said hold-down mechanism just can drive said hoodle and in this through hole, move; On said Workpiece carrier plate, be provided with bigger than nozzle od to be detected at least workpiece hole over against said v-notch place.During use, nozzle one end to be detected passes the workpiece hole of the v-notch and the Workpiece carrier plate of location-plate successively, starts hold-down mechanism then hoodle is moved to the v-notch direction; Until hoodle tightly against the flange in the nozzle to be detected outside, like this, the co-extruded effect of the dual-side of v-notch and hoodle; Nozzle to be detected is positioned, detects concentricity meter contact zones the lower end of nozzle then, at this moment rotary nozzle; Observe scale swing numerical value, can detect the concentricity numerical value of nozzle.
Further improvement as the utility model; Said hold-down mechanism just can drive the structure that said hoodle moves in this through hole: said hold-down mechanism comprises spring and setting nut; Said spring is in said through hole and between said setting nut and hoodle; Said setting nut is positioned at the end of said through hole away from said Workpiece carrier plate, is connected through screw-threaded engagement between said setting nut and the said through hole.Like this, the precession through setting nut and select the acting in conjunction of spring can make hoodle in through hole, move, to realize the pressuring action of hoodle to nozzle to be detected.
As the further improvement of the utility model, said two pillar plates are parallel and be located at interval the two ends of said substrate.
As the further improvement of the utility model, said v-notch, through hole, workpiece hole are two.
As the further improvement of the utility model, said hoodle is a steel ball.
The beneficial effect of the utility model is: this tool leans on two limits of v-notch to contact tangent with band detection nozzle; The location workpiece centre; The spring top clamping hoodle; To prevent that workpiece from pasting not tight V-type face and can't feel relieved in rotation, again owing to, therefore can reduce the friction force of workpiece in rotation greatly for the some contact; But this tool self-centering can be under the situation of not using 3D coordinate measurement, and the processor can use scale, detects the concentricity of workpiece voluntarily, not only saves time, and detects very convenient.
