Abstract

The utility model relates to a fast checking fixture capable of simultaneously detecting an included angle and a position of parts, and provides a simple and effective structure scheme for checking form and position errors of mechanical parts. A measurement method is basically characterized in that the plane of an angle needed to be measured is rotated to a position parallel to the bottom surface of the checking fixture, thus changing angle measurement into parallelism measurement; and a standard parallel height plane is arranged at a proper position of the checking fixture, so that a detection dial indicator can obtain a correct reference measurement height datum, and the complex processes of measuring the angle can be simplified through the method. In addition, a plurality of measurement bases are arranged on the checking fixture, so that a plurality of related angle parameters of a workpiece can be checked in one-time installation, thus being fast and accurate.

Description

A kind of quick cubing that can detect part angle and position simultaneously

Affiliated technical field:

The utility model is a kind of quick cubing that is used to detect mechanical component angle angle and position, provides a kind of simple and easy effective organization plan to the morpheme error-detecting of mechanical component.

Background technology:

The known common detection mechanical component angle angle and the appliance of position are the protractor that follows for a long time basically, height gauge etc., and detecting operation inconvenience, accuracy of detection is not high; The three-coordinates measuring machine that developed recently gets up then and be not suitable for the production scene and carry out in enormous quantities instant the detection and use, the Modern Manufacturing Technology high speed development now, urgent need will be researched and developed a series of novel appliance and satisfy demand of practical production.

Some relevant imaginations of carrying out shaped position degree context of detection that recently though some relevant patent disclosures arranged, " the position degree pick-up unit " of for example one " patent No.: CN201285267 ", be a kind of providing, come the position degree pick-up unit of measurement axis and hole location with plane positioning; " the position degree pick-up unit " of another " patent No.: CN201285265 " is to obtain the pick-up unit of V-type groove and hole location on the parts; " a kind of piston ring tread angle detection device " of another " patent No.: CN201434659 ", provide a kind of energy fast detecting piston ring tread angle whether to meet the pick-up unit of accuracy requirement, by elastic component interlock probe, displacement is presented on the angle display instrument, judge whether the piston ring gradient meets accuracy requirement, but all can not solve the problem that can detect mechanical component angle angle and aspect, position simultaneously of required solution herein.

Summary of the invention:

The present utility model a kind of employing be with multiple altitude datum, the quick cubing that is used to detect mechanical component angle angle and position that multi-angle pattern piece is formed provides a kind of simple and easy effective organization plan to the morpheme error-detecting of mechanical component.Use the mentality of designing that this programme provides, can solve many many size detection problems with open-and-shut way with complex angles workpiece.

The technical scheme that its technical matters that solves the utility model adopts is:

This cubing comprises a dial gauge and support, and a polygonal detection piece, this detection piece are used for fixing the detection workpiece.

Workpiece angle examination requirements by required detection designs corresponding angle pattern, and the altitude datum outshot that matches of the side setting in the angle master plate, and being convenient to provides a height positioning reference when making the angle height and position with dial gauge and detect.

A measuring basis face in the angle master plate is placed on the flat board, detect parallel on a workpiece to be detected angle plane with band gauge stand dial gauge with this measuring basis face, carry out parallel moving, if the altitude reading on this angle plane all remains unchanged on front and back position, with regard to the angle that this this angle plane is described be with the angle master plate in bottom measuring basis face be parallel, promptly angle is correct; If the altitude reading on this angle plane is consistent with corresponding height positioning reference in the angle master plate, the height and position that just shows this angle plane on the workpiece to be detected also is correct.

The basic characteristics of this measuring method are: the angle plane of required measurement is rotated to the position that parallels with the cubing baseplane, change measurement of angle into the measurement of paralleism; The parallel height plane that sets up standard in the suitable position of cubing makes to detect and can obtain a correct reference measure altitude datum with dial gauge, by such method, the complex process of measurement of angle is oversimplified processing.Simultaneously, by a plurality of measuring basiss are set on cubing, just can be in one-step installation, detect a plurality of angle correlation parameters of workpiece, not only soon but also accurate.

The beneficial effects of the utility model are:

This novel mentality of designing of taking the advanced person has been simplified the process of mechanical component angular detection and the structure of cubing greatly, can generally be extended in the mechanical detection operation, improves the accuracy of detection and the speed of production scene.
