Description

TECHNICAL FIELD

[0001] The utility model belongs to rotor processing technical field, specifically is a rotor outer diameter displacement detection device. BACKGROUND

[0002] During the operation of the rotor, its outer diameter may change due to various factors. This change may be caused by temperature changes, mechanical stress, wear or other external factors. If not detected and adjusted in time, it may cause the rotor to be unbalanced, thereby affecting the stability and efficiency of the equipment, and even causing failure. When the rotor is processed, the displacement of the outer diameter of the rotor needs to be detected in advance to ensure its normal operation and maintain its service life. The existing detection method is that the operator fixes the rotor to the workpiece tray manually, and then measures the outer diameter of the rotor by using a vernier caliper. Then the rotor is taken out and rotated several times, and the outer diameter is measured again. Since the clamping condition of the vernier caliper clamping the rotor is not fixed, the measurement needs to be repeated to ensure the accuracy of the measurement data. Moreover, the measurement of the outer diameter of the rotor twice or more times will cause deviation and influence due to the uncertain clamping condition. Manual measurement needs to be measured again after the rotor rotates, and then it needs to be manually placed on the workpiece tray for measurement, which requires more measurement time, slow detection efficiency and low detection quality.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0018] As shown in Figs. 1-3 A rotor outer diameter displacement detection device, comprising a main frame 2, a placing rack 3 is installed on the main frame 2, a servo motor 31 is installed on the placing rack 3, the servo motor 31 is connected with a lifting module 4 below, a placing table 41 is slidably arranged on the lifting module 4, a telescopic cylinder 42 is installed at the bottom of the placing table 41, a plurality of positioning pins 43 for fixing and positioning the rotor workpiece are fixedly installed on the telescopic cylinder 42;

[0019] The placement frame 3 is also equipped with a fixing frame 51, and a fixing plate 52 is installed on the fixing frame 51. The fixing plate 52 has a through hole, and a plurality of first cylinders 53 are arranged around the center of the through hole. A displacement sensor 54 is fixed on the first cylinder 53 in the direction of the center of the fixing plate 52. The displacement sensor 54 is used to align with the outer surface of the rotor.

[0020] The center of the placement platform 41, the rotor workpiece, and the center of the fixing plate 52 are located on the same axis.

[0021] Using the above structure, when detecting the outer diameter displacement of the rotor, the rotor workpiece is first rotated once by a rotating device. Then, a robotic arm picks up the rotor workpiece and places it on the placement platform 41. The piston rod of the telescopic cylinder 42 at the bottom of the placement platform 41 raises the positioning pin 43. The rotor workpiece has several holes, and the positioning pin 43 passes through the holes in the rotor workpiece, limiting and fixing the rotor workpiece on the placement platform 41. Subsequently, the servo motor 31 drives the rotor workpiece on the placement platform 41 to rise into the through hole and be at the same height as several unique sensors. At this time, the first cylinder 53 drives the displacement sensor 54 to move towards the center of the through hole to the predicted position. The outer diameter of the rotor workpiece is measured and calculated by the several displacement sensors 54. Servo motor 31 drives the rotor workpiece on the placement platform 41 to descend, and the robot arm removes the rotor workpiece. It then rotates twice, and the robot arm grips it again, placing it back onto the placement platform 41 for positioning and fixation. Servo motor 31 then lifts the rotor workpiece to the predicted position. The first cylinder 53 drives the displacement sensor 54 to move towards the center of the through hole, and the displacement sensor 54 again measures and calculates the outer diameter of the rotor workpiece. After two or more measurements and calculations, the servo motor 31 lowers the rotor on the placement platform 41 and resets it. Then, the telescopic cylinder 42 drives the positioning pin 43 to retract downwards, and the robot arm picks the rotor workpiece from the placement platform 41 to the next station. By arranging several displacement sensors 54 around the fixed plate 52, with the sensors 54 aligned with the outer diameter of the rotor workpiece at the center of the through hole, it is beneficial to automatically and quickly measure the outer diameter of the rotor workpiece multiple times, improving the quality and efficiency of the inspection, making the inspection faster, more convenient, and less labor-intensive.

[0022] Specifically, such as Figs. 1-3 As shown, the lifting module 4 has a slide rail 6, and the slide rail 6 is slidably mounted on a placement platform 41.

[0023] With the above structure, by setting the slide rail 6, the lifting module 4 drives the slide rail 6, and the slide rail 6 drives the placement platform 41 to move up or down automatically, which is conducive to automatically lifting the rotor workpiece to the predetermined detection position or completing the reset of the rotor workpiece.

[0024] As shown in Figs. 1-3 The placing table 41 is provided with a proximity sensor 7.

[0025] By arranging the proximity sensor 7, when the rotor workpiece placed on the placing table 41 is lifted below the fixing plate 52, the distance between the rotor workpiece and the fixing table can be detected in real time, the detection effect is good, the situation that the rotor workpiece is too high or too low compared with the predetermined detection position is reduced, and the rotor workpiece is always located at the correct detection position, so that the detection quality is improved.

[0026] As shown in Figs. 1-3 Each displacement sensor 54 is symmetrically provided with another displacement sensor 54 aligned with it on the placing table 41.

[0027] In the utility model, the displacement sensor 54 and the proximity sensor 7 are prior art.

[0028] By being provided with a plurality of displacement sensors 54 around the fixing plate 52, and the displacement sensors 54 being aligned with the outer diameter of the rotor workpiece in the center of the through hole, the outer diameter of the rotor workpiece can be automatically detected multiple times quickly, the quality and efficiency of detection are improved, the detection speed is faster, and it is more convenient and labor-saving.

[0029] As shown in Figs. 1-3 The placing rack 3 is provided with a solenoid valve 8. By arranging the solenoid valve 8, the solenoid valve 8 is connected with the servo motor 31, and the opening and closing of the servo motor 31 can be controlled through the solenoid valve 8.
