Abstract
An accurately assembled positioner comprises a base, a machine body, a horizontal adjusting bolt, a vertical adjusting bolt, a pin shaft, a horizontal nut, gaskets, a bearing (with a groove), a bearing fastening nut and a fastening bolt. The accurately assembled positioner is characterized in that the machine body is mounted on the base via the pin shaft so that the machine body can rotate around the base, the horizontal adjusting bolt and the vertical adjusting bolt are mounted on the machine body, the gasket and the bearing are mounted on the horizontal adjusting bolt, the gaskets are located on two sides of the bearing, and the gaskets are fixed with the bearing via double nuts. After the positioner is assembled, the positioner is fixed on a cross beam of an angle iron via the fastening bolt, and then the cross beam is mounted at a proper position.
Description
Technical field the utility model belongs to assembling and positioning device field, relates to specifically in a kind of large-scale precision equipment installation process, by datum line (center line etc.) adjustment component position, carry out the accurate auxiliary mould of installing.
Often there is the difficult problem of location difficulty in background technology in the assembling process of large-scale precision equipment.As in the installation process of large-size steam turbine, require the center line of each cylinder and bearing housing must be on same straight line, but in assembling process, be difficult to determine reference for installation.Even if the machining accuracy of each parts all meets the demands, if assembly precision is not enough, system still can't normally move, and problems such as fluctuation of service, operational efficiency be low perhaps occur.Therefore equip precision and whole system is played a part very important, it is necessary improving assembly precision.
Traditional assembly method: one is to use measurers such as meter ruler to carry out rough measurement and adjustment, and this method often can't reach very high precision; The 2nd, accurately to locate according to different equipment designs, the special frock of manufacturing, this method has increased the use of cost and material.
Summary of the invention the utility model is a kind of easy accurate positioning device of using in assembling process.Comprise pedestal, body, horizontal adjusting bolt, vertical adjusting bolt, bearing pin, horizontal nut, pad, band groove bearing, bearing clamp nut, fastening bolt.
The technical solution of the utility model is achieved in that
With bearing pin body is installed on the pedestal, makes body to rotate around pedestal; Horizontal adjusting bolt and vertical adjusting bolt are installed on the body; Pad and bearing are installed on the horizontal adjusting bolt, and pad is positioned at the both sides of bearing, re-use double nut with pad and bearing fixing; After the device assembling finishes, device is fixed in the measurement of angle bar, again crossbeam is installed to correct position with fastening bolt.
The utility model has designed a kind of universal simple tool, can be used for various installation processes by the line centering.Utilize the utility model and simple auxiliary article (angle bar, bolt, plain clamp) can make the sectional center line accurately, and according to this boost line assembling, assembly precision can reach in the 0.3mm.
Description of drawings
Fig. 1 is this device installation diagram;
Fig. 2 replenishes installation diagram for this device;
Fig. 3 is this device using method schematic diagram;
Fig. 4 is a dead eye measuring position enlarged drawing.
The specific embodiment comprises mainly that as the present invention as described in Fig. 1, Fig. 2, Fig. 3 pedestal 1 (band through hole 6), body 2, horizontal adjusting bolt 3, vertical adjusting bolt 4, bearing pin 5, horizontal nut 7, band groove bearing 8, pad 9, bearing clamp nut 10, the anti-skidding nut 11 of bearing form.Its essential characteristic is: with bearing pin 5 body 2 is installed on the pedestal 1, the 0-0.024mm matched in clearance is adopted in the cooperation of bearing pin, makes body 2 to rotate around pedestal 1; Horizontal adjusting bolt 3 and vertical adjusting bolt 4 are installed on the body 2; Pad 9 and bearing 8 are installed on the horizontal adjusting bolt 3, and pad 9 is positioned at the both sides of band groove bearing 8; With bearing clamp nut 10, the anti-skidding nut 11 of bearing pad 9 and band groove bearing 8 are fixed; After the device assembling finishes, device is fixed in the measurement 13,21 of angle bar, again crossbeam is installed to correct position (in the installation of turbine low pressure cylinder and corresponding bearing housing, measurement being loaded on bearing housing 16,20 outermost dead eye sides) with fastening bolt.The fixing finer wire 18 of 0.8mm on device 12,22 bearing groove; With the distance of inside micrometer 16 measuring steel wire to left and right, following three directions of dead eye of bearing housing 15,20.According to measurement result, usage level is regulated bolt 3 and is vertically regulated the position that bolt 4 is regulated steel wire, makes steel wire be positioned at the center of dead eye.After the fixed-site of steel wire, again with inside micrometer 16 measure before the low pressure (LP) cylinders half 17, the dead eye of low pressure (LP) cylinder later half 19 left and right, down and the distance of steel wire 18, adjust the later half position of half-sum before the low pressure (LP) cylinder according to measurement result, make the axial line of bearing housing and low pressure (LP) cylinder dead eye at same straight line.
