Abstract
The utility model provides a device for increasing the position tolerance measurement efficiency of a crankshaft, belonging to the technical field of crankshaft detection, in particular to a device for adjusting the parallelism of common axes of the crankshaft. The technical scheme provided by the utility model is as follows: the device comprises a base and a pair of V-shaped brackets fixed on the base in parallel, wherein one side of the bottom of each of the V-shaped brackets is rotatably matched with the base through a pin shaft; and the other side of the bottom of each of the V-shaped brackets is in threaded connection with the base through a screw. By adopting the device disclosed by the utility model, the disadvantages of the original detection means are effectively solved; the detection precision and measurement efficiency for the positional tolerance of crankshaft are increased; and the height error between two ends can be controlled within 0.003 mm, so that the detection precision and measurement efficiency for the positional tolerance of crankshaft are increased; furthermore, due to the wider base, the measurement stability of the device is increased.
Description
Technical field
The utility model provides a kind of device that is used to improve crank position tolerance measurement efficient, belongs to bent axle detection technique field, especially a kind of parallel device of bent axle common axis of adjusting.
Background technology
After bent axle process and completion of processing, project that process detects and finished product detection all is absolutely necessary.The detection of rod journal position of related features is one of key project in all measurement projects, be that measurement must be accurate to its requirement, and efficient wants high; Domestic in China; The detection of rod journal position of related features; Generally be to be put into the crankshaft two end king journal on two V-blocks that are positioned on the measuring table, measure two ends king journal peak, its numerical value is equated with dial gauge; So that it is parallel with measuring table that the common axis of bent axle is in, measure the position of related features of rod journal again; Because the mismachining tolerance of main bearing journal and V-block; King journal peak in two ends does not wait high often; Difference is about 0.05mm; And the crank-shaft link neck site error as the depth of parallelism, linearity below 0.01mm, make height such as two ends so must adjust the height of V-block, guarantee the accuracy of measurement result; In actual mechanical process, generally adjust with the mode of V-block bottom pad copper sheet, can fill up one deck superelevation often, go one deck low again; The long time of waste on high steps such as adjustment, efficiency of measurement and accuracy are all lower, thereby the operation turnover and the finished product that have just influenced bent axle are put in storage.
Summary of the invention
The purpose of the utility model will solve the problems of the technologies described above exactly, and a kind of parallel device of bent axle common axis of adjusting is provided, and is used for improving the accuracy and the efficiency of measurement of measurement.
Technical scheme: comprise a pair of V-type support of secured in parallel on base and the base, it is characterized in that: bottom one side and the base of V-type support are rotatably assorted through bearing pin, and opposite side is connected with whorl of base through screw.
Technique scheme also can be improved to: on said V-type support, cushion block is set.
Technique scheme also can be improved to: vertically disposed connecting rod on base, and connecting rod vertically connects cross bar through fixed knob, and the front end of cross bar is provided with dial gauge.
Technique scheme also can be improved to: on said base, concave groove is set, connecting rod is fixed on the concave groove through nut.Described concave groove and V-type support are point-blank.
Technique scheme also can be improved to: described concave groove is a Z type structure, its top and bottom respectively with two V-type supports point-blank.
Beneficial effect: the parallel device of adjustment bent axle common axis that adopts said structure; Solved the deficiency of original detection means effectively; Improve the accuracy of detection and the efficiency of measurement of crank position degree tolerance, can the two ends height error be controlled in the 0.003mm, improved the accuracy of detection and the efficiency of measurement of crank position degree tolerance greatly; And the utility model base broad, increased the stationarity of measuring.
