Detailed Description
In order to make the structure and function of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention.
Referring to fig. 1-2, a large turntable bearing assembly workbench comprises six guide rails 1, a movable square box 2 and six hydraulic jacks 3 for supporting; six guide rails 1 are evenly distributed on the ground along the circumferential direction, every two guide rails form an angle of 30 degrees, each guide rail 1 is provided with a movable square box 2, each movable square box 2 is provided with a hydraulic jack 3 for supporting, the hydraulic jacks 3 for supporting are in contact with the end face of the outer ring of the bearing and support the outer ring 12 of the bearing, and the six hydraulic jacks 3 for supporting are set to be started in a hydraulic synchronous mode and are provided with small hydraulic stations. The movable square box 2 is a main body part of the movable platform, and aims to improve the fit height to 800mm and the bearing height to reach the waist-aligning height, so that the fit and detection operations are facilitated. The outer ring 12 of the bearing is supported and fixed by the hydraulic jack 3 for supporting, so that the assembly and the sleeve combination of the large-scale bearing are convenient.
Further, each movable square box 2 is provided with a hydraulic jack 4 for detection, the hydraulic jacks 4 for detection are in end face contact with the inner ring 11 of the bearing, and the six hydraulic jacks 4 for detection are set to be started in a hydraulic synchronous mode and are provided with hydraulic stations. The six hydraulic jacks 4 for detection are used for synchronously moving the workpieces to do relative motion, and detecting the axial play, the end face runout, the radial runout, the tooth runout and the like of the bearing.
Further, a measuring meter 5 is arranged on one of the movable square boxes, the measuring meter 5 is fixedly connected to a meter seat movable support 7 through a magnetic meter seat 6, the meter seat movable support 7 is arranged on the movable square box 2, and a measuring meter probe is in contact with the inner diameter of the bearing inner ring 11 or the outer diameter of the bearing outer ring 12 and is mainly determined by looking at the position where the spigot diameter is located. The gauge stand movable support 7 is connected to the movable square box 2 through bolts, can be detached at any time, can be used for replacing and adjusting the measuring position, and can be used for measuring bearings with different diameters.
Further, a pulley 8 is arranged at the bottom of the movable square box 2, and the movable square box 2 is in sliding connection with the guide rail 1 through the pulley 8.
Further, the six guide rails 1 are arranged below the ground level by 10mm, each guide rail is 2 m long, and the installation flatness is controlled to be within 0.20mm. A protection foundation is needed to be used for preventing the sinking of the foundation from influencing the accuracy of the guide rail.
The supporting bearing inner ring or outer ring is determined according to the bearing structural characteristics and the required detected clearance, namely, the bearing inner ring 11 can be supported and fixed by a supporting hydraulic jack, and the axial clearance of the bearing outer ring 12 can be detected by the detecting hydraulic jack.
