Abstract
The invention provides a stator measuring frame which comprises a base. A main pillar is fixed on the base. A ball screw pair is arranged on the body vertical column. The lead screw of the ball screw pair is arranged at the side of the body vertical column. The lead screw nut of the ball screw pair is fixedly connected with a fixing frame. The fixing frame is nested outside the body vertical column, and is slidably connected with the body vertical column through a linear guiderail which is radially arranged along the body vertical column. A slewing bearing is arranged outside the fixing frame. The inner ring of the slewing bearing is fixed with the fixing frame. The outer ring of the slewing bearing is connected with a measuring device. According to the stator measuring frame, the ball screw pair is used for combining a motor structure, thereby realizing automatic centering and automatic horizontal height adjustment. Through arranging an upward movement stop device and a downward movement stop device, a lead screw nut and a speed reducer are used for realizing dual insurances, thereby preventing falling of the measuring device in measuring a large stator. Furthermore an added wireless control device can remotely control the measuring device. The measuring diameter reaches 12m, and the measuring precision can reach 0.05mm.
Description
Technical field
The present invention relates to a kind of stator measurement bay.
Background technology
The closed-in construction that the motor stator of hydroelectric facility is normally made up of unshakable in one's determination and coil.And in the Assembling Production process of motor stator, likely there will be the problem of the right alignment generation deviation of motor stator integral level degree and lamination, this directly will have influence on the air gap of electric machine rotor, thus finally has influence on the performance of motor.The diameter that existing stator measurement bay can both be measured is all smaller, and precision not high be usually all that manual adjustments is measured after height and length well.
Summary of the invention
The problem to be solved in the present invention is to provide simple, easy to use can be used in of a kind of structure and detects the right alignment of major diameter stator and the stator measurement bay of flatness.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of stator measurement bay, is characterized in that: comprise base, and described base top is fixed with main post, described main post is provided with ball screw assembly, and the leading screw of described ball screw assembly, is arranged on main post side; The feed screw nut of ball screw assembly, is fixedly connected with a fixed mount; Described fixed mount is nested in outside described main post, and the line slideway arranged along main post radial direction by, is slidably connected with main post; Arrange a turntable bearing outside described fixed mount, inner ring and the described fixed mount of described turntable bearing are fixed, outer 1 circle connection one measurement mechanism of described turntable bearing.
Further, described measurement mechanism comprises swivel mount, spandrel girder and dip stick, described swivel mount is connected with the outer ring of described turntable bearing, can move in a circle around main post, one end of described spandrel girder is fixedly installed on the side of swivel mount, and the other end of described spandrel girder is connected with dip stick extension type.
Further, described chassis interior is provided with variable-frequency motor and reductor, and described variable-frequency motor controls ball screw assembly, and described reductor is connected with variable-frequency motor.
Further, the top of described main post is provided with up stop means, and bottom is provided with descending stop means.
Preferably, described variable-frequency motor also connects a wireless controller.
Preferably, described dip stick is carbon fibre material.
Optionally, described ball screw assembly, can be replaced trapezoidal screw pair.
The advantage that the present invention has and good effect are: adopt ball screw assembly, in conjunction with electric machine structure, can self-centering, automatic adjustment level height, uplink and downlink stop means is set, utilize feed screw nut and reductor double insurance, the coming off of measurement mechanism when avoiding measuring large-size stator, the control device of wireless simultaneously installed additional also can long-distance remote control; Spandrel girder and dip stick are carbon fibre material, and quality is light, is easy to use and measure, and measuring diameter can reach 12m, and precision can reach 0.05mm.
