The utility model discloses a crankshaft key groove symmetry detecting tool, which consists of a beam plate (1), a front V-shaped main shaft neck positioning rack (2), a rear V-shaped main shaft neck positioning rack (3), a dial indicator rack (4), dial indicators (5a and 5b) and a crankshaft pin positioning rack (6), wherein supporting legs (6a and 6b) are symmetrically arranged at the left and right ends of the crankshaft pin positioning rack (6); the left and right dial indicators (5a and 5b) are respectively arranged on a horizontal rack plate (41) of the L-shaped dial indicator rack (4) in a left and right symmetry mode; and the whole tool has a left and right symmetry structural shape. The detecting tool is easy and convenient to use, greatly reduces the requirement for the detection level of inspection personnel, is not limited by sites and the like in detection, realizes on-line detection of production, and is high in detecting efficiency.
Description
Technical field
the utility model relates to a kind of cubing that is used for crankshaft key slot symmetry on-line quick detection.
Background technology
The detection of crankshaft key slot symmetry in the past is that bent axle is placed on the v block of platform, and the way that adds lever indicator with vernier height gauge detects, and concrete detection method is following:
The first step: the bent axle that will process keyway is sling, and is placed on two V shape irons of platform, and the location king journal is contacted with two V shape irons;
Second step: the keyway gauge block is inserted crankshaft key slot, two benchmark king journal centers are transferred to wait height with being installed in lever indicator on the vernier height gauge then;
The 3rd step: benchmark crank pin center is transferred to and two benchmark king journal center height such as grade, and promptly benchmark king journal center line is parallel with platform with the plane that the crank pin center line forms;
The 4th step: detect the key tile height in the keyway with another piece lever indicator, record numerical value;
The 5th step: the length direction (promptly axial) along bent axle drags dial gauge, observes dial gauge reading changing value;
The 6th step: with bent axle Rotate 180 degree vertically, repeat the 3rd step, FOUR EASY STEPS again, record detects key tile height numerical value;
the 7th step: with above twice key tile height numeric ratio, count difference, and then with axial detection numeric ratio, get its maximal value.
The problem that
this detection method exists is more.The firstth, checked operation personnel's detection level is had relatively high expectations; The secondth, it is bigger to detect error; The 3rd is to detect to receive the limitation in place, and the 4th is that operation steps is many, and efficient is low.
The utility model content
The purpose of
the utility model provides crankshaft key slot symmetry on-line quick detection cubing a kind of simple in structure, easily manufactured, easy to use.
the utility model crankshaft key slot symmetry cubing is made up of beam slab 1, preceding V-arrangement king journal locating rack 2, back V-arrangement king journal locating rack 3, dial gauge dial framework 4, two dial gauge 5a, 5b, crank pin locating racks 6; Before V-arrangement king journal locating rack 2, back V-arrangement king journal locating rack 3 be fixedly connected on respectively on the lower surface of front and back ends of strip beam slab 1; The fork-shaped crank pin locating rack 6 that is the left-right symmetric leg is fixedly connected on the lower surface at beam slab 1 middle part; L shaped dial gauge dial framework 4 is fixedly connected on the front end face of preceding V-arrangement king journal locating rack 2; Left-right symmetric offers left and right sides dial gauge 5a respectively on the horizontal frame plate 41 of L shaped dial gauge dial framework 4,5b installs and fixes hole 42a, 42b; Left and right sides dial gauge 5a, 5b install through its sounding rod cover and fixed orifice 42a, 42b matching and fixing, the whole left-right symmetric formula planform that forms.
Earlier left and right two dial gauge 5a, 5b are imitated standard on same surface level when
the utility model cubing is used, be about to two dial gauges after the certain decrement of adjustment on the same surface level, two dial gauge pointers are transferred to " 0 " position.
Detect:
Step 1; The preceding V-arrangement king journal locating rack 2 of cubing is placed on the two location king journals 8 of bent axle with back V-arrangement king journal locating rack 3; Along the circumferential direction to a sideway swivel cubing; The leg 6a of crank pin locating rack 6 one sides on the cubing is contacted with the crank pin 81 of bent axle, contact with the key piece 9 of bent axle, write down the reading that dial gauge shows this moment with the gauge outfit of the dial gauge 5a of crank pin 81 homonymies;
The difference of
two meter readings is the radial symmetry degree of crankshaft key slot to the common plane of crankshaft axis and the formation of crank pin center line.
step 3: on the basis of aforesaid operations, move cubing backward; The leg 6a/6b of crank pin locating rack 6 one sides will keep contacting with crank pin 81 in the moving process; (this detects only needs a direction to observe dial gauge pointer variable quantity this moment; Bent axle need not overturn), this variable quantity is shaft with key way to symmetry.Two kinds of symmetries are relatively got its maximal value, are the symmetry of this keyway to this bent axle.
the utility model cubing is simple in structure, easily manufactured, easy to use.Reduce requirement greatly, reduced the detection error, detect the limitation do not receive place etc. reviewer's detection level; Realize producing online detection, detection efficiency is high, and the operator is after processing keyway; Oneself just can detect whenever and wherever possible; No longer need bent axle be hung down, be put on the verifying bench, by reviewer's detection of specialty.
The utility model cubing accuracy of detection and platform detect and the three-coordinates measuring machine contrast:
