Description

Roundness and coaxiality detection device for camshaft

Technical Field

The utility model relates to a camshaft processing field specifically is a circularity and axiality detection device of camshaft.

Background

The camshaft is used as an important part of an engine, the requirement on machining precision is high, the transmission efficiency of the engine is directly related, the length of the camshaft is long, a plurality of cams and round tables are arranged along the length direction, the roundness of each round table and the coaxiality between the round tables are one of technical parameters for quality inspection measurement, at present, a dial indicator is mainly used for detecting the parameters, and due to the fact that the length of the camshaft is long, the number of detection points is large, operation is inconvenient during detection, and the detection accuracy is not high.

Disclosure of Invention

The utility model aims at providing a roundness and axiality detection device of camshaft in order to solve present detection circularity and axiality because camshaft length is longer, and the check point is more, operates inconveniently during the detection, and the not high problem of detection accuracy degree.

The utility model has the following concrete scheme: the utility model provides a roundness and axiality detection device of camshaft, includes the workstation, and two V-arrangement support frames have been placed at the workstation top, a portal frame is equipped with at the workstation top, and the portal frame top is equipped with a horizontally cylindrical slide bar, and the slide bar below is equipped with the crossbeam, be equipped with a plurality of sleeve on the slide bar, the slide bar translation or rotation can be followed to the sleeve, and every sleeve outer wall all is equipped with first kilo minute table installation interface.

Every sleeve outer wall still is equipped with extension board A, and extension board A outer end is equipped with second amesdial installation interface.

Sleeve outer wall still is equipped with extension board B, and extension board B and extension board A are located the crossbeam both sides respectively, extension board A and extension board B quilt when the sleeve is rotatory the crossbeam blocks spacingly, telescopic rotation angle scope is 120 ~ 180.

The sleeve outer wall is equipped with the locking bolt.

The working principle of the utility model is as follows: place the camshaft on two V-arrangement support frames, install the amesdial on the sleeve, move the camshaft suitable position the amesdial of being convenient for and detect, remove each sleeve to the check point that corresponds before detecting, rotatory sleeve adjusts the measurement angle of amesdial, then manual rotation camshaft observation amesdial reading can obtain the circularity that corresponds the machined surface, the reading difference through the different amesdials of analytical computation can obtain the axiality of different machined surfaces.

The utility model discloses following beneficial effect has: 1. the operation is more convenient, and the detection accuracy is improved; 2. setting a first dial indicator mounting interface and a second dial indicator mounting interface, selecting and mounting a dial indicator according to an actual position, and detecting different positions of the camshaft; 3. the support plate A and the support plate B play a role in limiting the rotation position of the sleeve.
