Abstract
The present invention discloses a location degree detection tool of a turbocharger turbine casing. The location degree detection tool of the turbocharger turbine casing comprises a detection platform, wherein one side of the detection platform is equipped with an inclined wedge pair via a support, and the inclined wedge plane of the inclined wedge pair is attached to the plane of an air inlet of the to-be-detected turbine casing; an adjustable push rod is arranged on the detection platform to match the inner side of the air inlet of the turbine casing, and the detection platform is equipped with a telescopic push rod relative to the other side of the inclined wedge pair. The location degree detection tool of the turbocharger turbine casing is based on the pair of inclined wedges which move in the opposite directions, so that the elevation movement is obtained in one direction while the inclined wedges advance along the other direction, and accordingly, the gapless attachment with a workpiece is guaranteed.
Description
Technical field
The present invention relates to a kind of position detecting tool, relate in particular to a kind of turbocharger turbine shell position detecting tool.
Background technology
At present, machining center adds man-hour turbocharger turbine shell is carried out to position, hole, and engine charge actinal surface is the sense of rotation benchmark of whole part.The use of this benchmark has directly determined whether hole location can reach process capability index: CPK>1.67, in addition, this corner is except carrying out three-dimensional coordinates measurement, field control means are always unreliable, and MSA (measurement System Analysis) test and appraisal of on-the-spot cubing do not reach target call yet.Because field position degree cubing is the double link detent mechanisms that adopt in the time determining directional reference more, mouth of pipe direction location is inaccurate, be not enough to guarantee the Repeatability and Reproducibility index of measurement, cannot measure accurately and reliably assessment for field control provides, cause Site Detection can not effectively find defective, the inspection frequency that three-dimensional covers is very limited, even detect under the frequency and still find that there is unacceptable product in limited three-dimensional, process faces out of control.
Summary of the invention
The object of the present invention is to provide a kind of turbocharger turbine shell position detecting tool, to solve the problem that in prior art, turbocharger turbine shell position detecting tool exists.
For reaching this object, the present invention by the following technical solutions:
A kind of turbocharger turbine shell position detecting tool, it comprises detection platform, wherein, one side of described detection platform is provided with wedge pair by bearing, the cammed surface of described wedge pair and turbine case air inlet actinal surface to be detected fit, coordinate the inner side of described turbine case air intake opening to be provided with adjustable ejector rod in described detection platform, and be provided with Extendible knockout pin with respect to the opposite side of wedge pair in described detection platform.
Especially, described adjustable ejector rod comprises the first mount pad, connects rocking bar, push rod and top, and one end of described connection rocking bar is articulated with on described the first mount pad, and the other end is fixed with push rod by gib screw, and described top is installed on the end of described push rod.
Especially, described Extendible knockout pin is installed in described detection platform by the second mount pad, in described the second mount pad, flexible push rod is set.
Especially, described top is made of plastics, and it is conical.
Beneficial effect of the present invention is, compared with prior art described turbocharger turbine shell position detecting tool adopts the wedge pair of move toward one another, advance simultaneously along a direction at wedge, obtain in another one direction the motion that raises, ensure like this gapless laminating with workpiece.Through having the following advantages in the checking of turbine case process:
1) measurement System Analysis reached repeatability and in existing property (R & R) requirement.
2) exactly production run workpiece is assessed, and this monitoring is had ready conditions and is undertaken by 100% the detection frequency.
3) be site error analysis, debugging provides technique guarantee, coordinates the use of mouth of pipe face high-band table rule, for the accurate control that improves processing location and processing site cutter compensation opportunity provides reliable means.
4), through on-line monitoring and processing and debugging, through proof procedure Capability index CPK>1.67, thereby make process capability index meet automobile industry amount product quality control ability standard.
