Background technology
Connecting rod is the very important high-speed moving part of engine, therefore higher to the accuracy requirement of connecting rod machining, the wherein processing of crank pin end pore, status requirement to big end hole axis and plane verticality is very high, if this verticality is overproof, when the engine link parts assemble, will produce between connecting rod and the check of crankshaft quality problems such as sideshake is too small.For preventing that the overproof connecting rod of verticality from flowing into assembling, the reviewer must detect at the measurement flat board, and is not only time-consuming but also require great effort.If be equipped with the special electronic measuring instrument in the production scene, cost compare is expensive.
Summary of the invention
The purpose of this utility model is to provide a kind of comparatively fast and convenient big end axially bored line and plane verticality survey instrument, realizes the fast detecting to big end axially bored line and plane verticality data, thereby improves detection efficiency, controlled working quality.
The utility model is achieved in that big end axially bored line and plane verticality survey instrument, comprises base plate, support, clamp axle, elastic expansion-sleeve, cover for seat, handle, dial gauge, the location backing pin, tailstock, rhombus pin, proofread and correct the sample circle, keyway, pin and holding screw, support and tailstock be vertical being fixedly installed on the base plate two ends respectively, cover for seat is installed on the support, clamp axle and be installed on the cover for seat, an end internal thread that clamps axle and handle have keyway to be threaded on the clamping axle, pin is installed on the cover for seat inserts in the keyway, will clamp axle and carry out circumference calmly
The position, the two ends internal conical surface of elastic expansion-sleeve, be positioned at simultaneously on the outer conical surface of cover for seat and clamping axle, keep the gap between the inner cylinder face of elastic expansion-sleeve and the cover for seat, keep the gap between the end face of cover for seat and clamping axle, crank pin end pore is installed on the external cylindrical surface of elastic expansion-sleeve, and dial gauge is fixedly installed on the cover for seat, measure between gauge outfit and the big end plane and keep in touch state, realize the measurement of big end axially bored line and plane verticality.
The utility model can accurately record easily in the production scene verticality actual numerical value on big end axially bored line and plane, reduce overproof finished product connecting rod and flow into assembling line, cause quality accident to occur, and simple to operate, with low cost, be applicable to the big end axially bored line of different pore size and the measurement of plane verticality.
Description of drawings
Fig. 1 is big end axially bored line and plane verticality survey instrument schematic diagram.
Fig. 2 is crank pin end pore big end hole location schematic diagram.
Fig. 3 proofreaies and correct sample circle schematic diagram.
Among the figure, 1 is base plate, and 2 is support, and 3 for clamping axle, and 4 is elastic expansion-sleeve, and 5 is cover for seat, 6 is handle, and 7 is dial gauge, and 8 are the location backing pin, and 9 is tailstock, and 10 is the rhombus pin, and 11 for proofreading and correct the sample circle, 12 is measured connecting rod, and 13 is keyway, and 14 is pin, and 15 is measured plane, and 16 is holding screw.
Embodiment
Such as Fig. 1,2, shown in 3, big end axially bored line and plane verticality survey instrument comprise base plate 1, support 2, clamp axle 3, elastic expansion-sleeve 4, cover for seat 5, handle 6, dial gauge 7, location backing pin 8, tailstock 9, rhombus pin 10, proofread and correct sample circle 11, keyway 13, pin 14 and dial gauge holding screw 16, support 2 and tailstock 9 be vertical base plate 1 two ends that are fixedly installed in respectively, cover for seat 5 is installed on the support 2, clamp axle 3 and be installed on the cover for seat 5, an end internal thread that clamps axle 3 and handle 6 have keyway 13 to be threaded on the clamping axle 3, pin 14 is installed on the cover for seat 5 to be inserted in the keyway 13, to clamp axle 3 and carry out circumferential registration, the two ends internal conical surface of elastic expansion-sleeve 4 is positioned at cover for seat 5 and the outer cone that clamps axle 3 simultaneously
On the face, keep the gap between the end face of cover for seat 5 and clamping axle 3, crank pin end pore is installed on the external cylindrical surface of elastic expansion-sleeve 4, dial gauge 7 is fixedly installed on the cover for seat 5, support 2 is mainly used to the positioning and clamping of crank pin end pore and measures verticality numerical value, rhombus pin 10 on the tailstock 9 is the coarse positioning of connecting rod small end hole, plays guide effect when connecting rod is installed.During measurement, at first must proofread the zero-bit of 3 dial gauges 7 on the cover for seat 5, clockwise direction rotary handle 6, make elastic expansion-sleeve 4 be in the state of being totally released, then load onto and proofread and correct sample circle 11, when correction sample circle 11 contacts with the location backing pin 8 of cover for seat 5 lower ends, be rotated counterclockwise handle 6, drive clamping axle 3 mobile to the inside, clamping under the acting force of axle 3, so that clamp 30 ° of outer conical surface in axle 3 outsides and 30 ° of outer conical surface in cover for seat 5 outsides, contacting with 30 ° of internal conical surfaces of inboard, elastic expansion-sleeve 4 two ends simultaneously, make the synchronous spreading in elastic expansion-sleeve 4 two ends, clamp and proofread and correct sample circle 11, the measurement gauge outfit contacts with the measurement face of proofreading and correct sample circle 11 and measures, and the pointer that then will be distributed in 3 dial gauges 7 on the support is corrected to zero-bit, loosen the holding screw 16 on the cover for seat 5, finish check and correction.Clockwise direction rotary handle 6 makes elastic expansion-sleeve 4 be in the state of being totally released, and after will proofreading and correct sample circle 11 and pulling down, can measure the verticality on big end axially bored line and plane, and operation steps is with top identical.When contacting with the location backing pin, measured connecting rod 12 planes clamp measured connecting rod 12, the measured connecting rod 12 big end hole faces of cylinder are contacted with the elastic expansion-sleeve external cylindrical surface fully, at this moment, be distributed in 3 numerical value that dial gauge obtains on the support, the difference of maximal value and minimum value is exactly the verticality numerical value on measured connecting rod 12 big end hole axis and plane in 3 tables.
The utility model can accurately detect easily in the production scene verticality actual numerical value on big end axially bored line and plane, reduce overproof finished product connecting rod and flow into assembling line, avoid the generation of quality accident, simple to operate, with low cost, be applicable to the big end axially bored line of different pore size and the measurement of plane verticality.
