Description
Technical field
The utility model relates to piston pin hole circlip groove field, in particular, relates to pulsation measurement cubing in footpath at the bottom of a kind of piston pin hole circlip groove.
Background technology
The piston stopper groove is the groove that extends the position processing of a bit of distance at the piston pin hole cylindrical inwards, is used to install the back-up ring of piston pin, prevents that piston pin from coming off.Piston stopper bottom land footpath is no more than 0.2mm with respect to general requirement of beating of piston pin hole center line, if it is overproof directly to beat at the bottom of the circlip groove, circlip groove is prone to eject makes piston pin produce axially play, influences the operate as normal of piston.
The one segment distance position, the inside of the pin-and-hole of circlip groove is difficult to measure so it is beated.In the former production run, the main method that adopts frock to guarantee of beating in footpath is controlled the detection of this project at the bottom of the circlip groove, and it is qualified promptly in process, to control the beating of axle of rising, and it is qualified then directly to beat at the bottom of the circlip groove.And the procedure arrangement of car bumper ring recess after precision bored hole, thereby can guarantee the precision of the axle degree size of circlip groove and pin-and-hole.Now, in order to enhance productivity, suitable adjustment has been carried out in the technological process of piston processing, the manufacturing procedure of circlip groove is incorporated into heavy boring pin-and-hole operation in advance.Under this technological process, the processing of circlip groove can settle at one go when guaranteeing roughing, needs a cover cubing can detect the skew of beating of circlip groove.
Existing measurement cubing is to utilize lever principle to accomplish this detection.Its shown in accompanying drawing 1, measure excellent shell 7 ' through coupling bolt 1 ' be fixed on support 2 ' on, dial gauge 4 ' connection table bar 3 ' connections outward six square bolts 5 ', outer six square bolts 5 ' with fork 10 ' fix; The fork other end install gauge head 9 ', through central shaft 6 ' rotation form lever construction, utilize lever principle; Earlier adjustment centring ring 11 ' with gauge head 9 ' distance, make piston run into centring ring 11 ' time gauge head 9 ' just in time and be stuck in the circlip groove place, adjust again dial gauge 4 ' with outer six square bolts, 5 ' distance; Make on the measurement face of outer six square bolts 5 of dial gauge 1 ' be pressed in ' top, depress outer six square bolts 5 ', gauge head 9 ' indentation is measured in the hole of rod; Pass pin-and-hole then and measure rod, run into 11 ' time of centring ring when piston, unclamp outer six square bolts 5 '; Because spring 12 ' elastical retraction, fork 10 ' right-hand member is upwarped, left end descends; Gauge head 9 ' lean out is pressed in circlip groove bottom, then with housing screw 8 ' with gauge head 9 ' compress; Fixing adjustment dial gauge 4 ' the precompressed amount, piston is rotated a circle, observation dial gauge 4 ' value of reading.
In above-mentioned measurement cubing; It exists in following deficiency: at first, whole measurement cubing is to be accomplished by lever principle to measure, and just has certain included angle during six square bolts motion so outside; The generation that this will certainly cause measuring principle property error is inevitable; Secondly, total is complicated, needs when mounted to adjust the distance of centring ring to gauge head earlier, and then will adjust the distance of dial gauge and outer six square bolts, makes the whole erection time also very long like this; Once more, it is poor that this measures cubing versatility, to the piston that differs greatly with the pin-and-hole diameter specifications, this cubing need to measure excellent shell 7 ', gauge head 9 ', fork 10 ' change accordingly, increased manufacturing cost so again virtually.
Therefore, how designing a cover does not have original reason error, simple in structure, convenient inspection, has the measurement cubing of certain versatility simultaneously, is the problem that those skilled in the art need solution badly.
