Description

A coaxiality detection device for a waveguide switch shaft assembly

technical field

The invention relates to a coaxiality detection tool of a rotating shaft, in particular to a coaxiality detection device of a waveguide switch rotating shaft assembly.

Background technique

The motor of the waveguide switch, the motor output shaft, the shaft on the motor output shaft, and the flange between the motor and the shaft need to be tested for coaxiality before assembly. For coaxiality testing, the shaft is generally placed on a V-shaped table, and then Use a dial indicator to detect both ends of the rotating shaft, and push the dial indicator from one end of the rotating shaft to the other. The rotating shaft and the motor must be coaxial, but the V-shaped stage cannot guarantee the coaxial rotation of the rotating shaft and the motor during detection, because the rotating shaft and the motor Different shafts lead to errors in the detection of the coaxiality of the rotating shafts.

Contents of the invention

In order to solve the defect that the rotating shaft and the motor are not coaxial during detection in the prior art, the present invention provides a coaxiality detection device for a waveguide switch rotating shaft assembly.

The technical solution of the present invention is: a coaxiality detection device for a waveguide switch shaft assembly, including a dial indicator and a positioning seat, a positioning groove is provided on the positioning seat, and a sliding device for installing The mounting seat of the waveguide switch is provided with a through groove for the waveguide switch shaft to be inserted in the mounting seat, and the sliding direction of the mounting seat in the positioning groove is parallel to the axis of the rotating shaft. The detection window where the dial indicator probe contacts the rotating shaft.

Preferably, a support seat for supporting the end of the rotating shaft away from the waveguide switch motor is also provided on the mounting seat.

Preferably, the support seat is a hole, and a bearing is arranged in the hole.

Preferably, the positioning groove is a V-shaped groove.

Preferably, a positioning portion that cooperates with the positioning groove is provided on the mounting base.

Preferably, the positioning portion is an arc surface.

Preferably, the mounting base is provided with threaded holes for screwing with the waveguide switch screws.

Beneficial effects of the present invention: the waveguide switch is installed on the mounting seat, and the sliding direction of the mounting seat in the positioning groove is parallel to the axis of the rotating shaft, so that the motor and the rotating shaft remain coaxial, thereby ensuring no error in the coaxiality detection of the rotating shaft.

Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

The technical scheme of the present invention is as follows: a coaxiality detection device of a waveguide switch shaft assembly, including a dial indicator and a positioning seat 1, as shown in Figure 1, a positioning groove 2 is provided on the positioning seat 1, and a positioning groove 2 is arranged on the positioning groove 2 A mounting seat 3 for installing the waveguide switch is slidingly arranged. The mounting seat 3 can be cylindrical, and the mounting seat is on the same axis as the rotating shaft. There is a through groove 4 for the waveguide switch rotating shaft to be inserted in the mounting seat 3. Between the rotating shaft and the through groove There is a gap between them, enough for the rotating shaft to rotate in the through groove. The sliding direction of the mounting seat 3 in the positioning groove 2 is parallel to the axis of the rotating shaft. There is also a detection window 5 on the mounting seat 3 for the contact between the dial gauge probe and the rotating shaft. , the detection window is set corresponding to the positions at both ends of the rotating shaft.

In order to prevent the rotating shaft from moving and affect the coaxiality of the rotating shaft and the motor, as shown in Figure 2, a supporting seat 6 is provided on the mounting seat 3 to support the end of the rotating shaft away from the waveguide switch motor. The supporting seat 6 is a hole. Bearings are provided, and the bearings are used for positioning and rotating shafts, and the rotating shafts can also rotate in the bearings.

As shown in FIG. 1 , the positioning groove 2 is a V-shaped groove, and a positioning portion 7 cooperating with the positioning groove 2 is provided on the mounting base 3 , and the positioning portion 7 is an arc surface or a V-shaped surface.

As shown in Figure 2, the mounting base 3 is provided with a threaded hole 8 that is threadedly matched with the waveguide switch screw. The threaded hole is set on the end face of the mounting base. Lan on.

Working process: as shown in Figure 3, the reference numeral 9 is a dial gauge, and the dial gauge 9 is zeroed based on the surface of the rotating shaft. 6 position values, subtract the minimum value from the maximum value to get the runout at the proximal end of the shaft; move the mounting base so that the 9 heads of the dial indicator are in contact with the far end of the shaft, and start to test the runout at the far end of the shaft, and pass the test at the proximal end of the shaft The runout method is used to detect the runout at the far end of the rotating shaft, and whether the coaxiality of the rotating shaft meets the requirements is judged according to the runout at the proximal end and the far end of the rotating shaft.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present invention are included in the protection scope of the present invention.
