Description
Technical field
The utility model is about measuring the cubing of arc surface internal diameter, in particular for detecting the cubing of clutch can alley circular arc.
Background technology
Clutch can is a strength member of rzeppa joint, the precision of its alley arc size just is directly connected to the fit-state of interior steel ball of alley and alley, and then have influence on its serviceable life, it is very big to use common survey instrument to measure difficulty, and measuring error is big.Use advanced three-coordinates measuring machine, can carry out the measurement of three-dimensional dimension to tested part, have advantages such as measuring accuracy height, the automatic processing of data, but because its complex structure, price are high, general medium-sized and small enterprises can't be purchased, and its measuring process is more loaded down with trivial details, is difficult to promote the use of in the production scene.Detection method commonly used at present is to adopt a standard-sized detection steel ball, appearance is smeared red lead powder, to detect steel ball then and in alley, slide, judge the fit-state of steel ball and alley, thereby make whether qualified judgement by the scraping vestige of analyzing and testing steel ball surface red lead powder.Though the method is easy, accuracy is not high, and erroneous judgement, and operating personnel easily needs abundant operating experience, and is therefore, very inconvenient when online detection or upper frequency detect.
The disclosed a kind of arc radius of Chinese patent literature is measured cubing (application number: 200820005263.1), measure the arc surface radius by relative method, mainly comprise clock gauge, cubing body, straight pin, calibration block, described cubing body both sides are bending, and be respectively equipped with straight pin, straight pin and clock gauge gauge outfit and arc surface applying to be checked change by the action of measurement with the calibrated bolck arc surface, measure the radius of circular arc again through calculating.But it is applicable to the measurement of column arc surface, and because the restriction of structure makes it be difficult to adapt to the less occasion of arc radius, therefore also inapplicable detection to clutch can alley circular arc.
The utility model content
The utility model is in order to overcome the shortcoming that prior art cost height, the online detection of incompatibility and high-frequency detect, and provides that a kind of cost is low, precision is high, need not to calculate, clutch can alley circular arc cubing conveniently.
The utility model is achieved by following technical proposals: it comprises underframe, be located at the work piece platform that is used for tested clutch can location above the underframe, the measurement bracket of fixedlying connected with underframe, be located at measurement bracket one side and the swing arm hinged side by side with it, described work piece platform is fixedlyed connected with underframe, the front end of described measurement bracket is provided with cydariform positioning head fixedly connected with it and that match with tested clutch can alley circular arc, cydariform positioning head axle center is provided with through hole, be provided with the sounding rod that is slidingly matched with it in the through hole, sounding rod two ends end to end all is semisphere or bullet-headed, its tail end compresses with the swing arm front end and cooperates, also be provided with the clock gauge that is used to measure the swing arm oscillating quantity on the underframe, the clock gauge gauge outfit compresses with the swing arm rear end and cooperates, and sounding rod and clock gauge table bar are all perpendicular to swing arm.The utility model is not directly measured the size of clutch can alley circular arc, but adopt relative method that it is made whether qualified judgement, detected clutch can is placed on the work piece platform, fit in the end face of clutch can and work piece platform surface, the clutch can cavity covers the front end of measurement bracket, at this moment, the cydariform positioning head that matches with clutch can alley circular arc can slip in the alley, the sounding rod head of being located in the cydariform positioning head axis through-hole is subjected to compressing of alley arc surface, generation endwisely slips, and then promotion and sounding rod tail end compress the swing arm that cooperates and produce a swing, and gauge outfit compresses the clock gauge that cooperates with the swing arm rear end promptly can show its oscillating quantity.Before the measurement, measure earlier the clutch can that two alley circular arcs have upper and lower dimension limit respectively, can obtain the limit oscillating quantity of two swing arms, when measuring clutch can alley circular arc, the oscillating quantity of swing arm is positioned at the scope of above-mentioned two limit oscillating quantities, and it is qualified then can be judged to, and is defective if exceed above-mentioned scope, whole testing process is simple and direct fast, is suitable for on-line quick detection.Because sounding rod and clock gauge table bar are all perpendicular to swing arm, sounding rod tail end and clock gauge gauge outfit are in the slippage on swing arm surface in the time of can reducing the swing arm swing, thereby reduce wear, prolong the serviceable life of cubing, the semisphere at sounding rod two ends or bullet-headed design, make contacting of itself and clutch can alley and swing arm be the some contact, thereby can guarantee the accuracy that detects.
As preferably, described sounding rod axial line is parallel with the work piece platform outside surface, and distance between the two equals the distance of tested clutch can alley center and clutch can end face.Because it is equal that above-mentioned two distances are made as, and make sounding rod be positioned at clutch can and cross on the xsect at alley center, thereby the circular arc that can guarantee measurement point on sounding rod and the alley is positioned at same plane.
As preferably, compress abutting end with sounding rod on the swing arm and be provided with the sounding rod contact stud, its other end is provided with the gauge outfit contact stud, the sounding rod tail end compresses with the sounding rod contact stud and cooperates, the clock gauge gauge outfit compresses with the gauge outfit contact stud and cooperates, and the swing arm oscillation centre is 0.5: 1～1: 1 to the distance of sounding rod axial line with its ratio to the distance of clock gauge table bar axial line.Lever amplification by swing arm can improve the precision of measurement, two contact studs set up the wearing quality that can improve swing arm, thereby prolong the serviceable life of cubing.
As preferably, between swing arm and measurement bracket, be provided with spring, underframe is provided with the table support of fixedlying connected with it, and clock gauge is axially movable to be socketed on the table support.Clock gauge and the axially movable socket of table support, the convenient clock gauge position of adjusting guarantees that its gauge outfit cooperates with the mortgage of gauge outfit contact stud, is provided with spring between swing arm and measurement bracket, make the sounding rod head can be close to tested clutch can alley arc surface, with the accuracy of guaranteeing to detect.
Therefore, the utlity model has following beneficial effect: (1) is simple in structure, and cost is low.(2) measurement result need not to calculate, and detection speed is fast, can adapt to online detection, and reduces reviewer's workload.(3) artifical influence factor is little, and the error of detection is little, the accuracy height.
