Abstract
The utility model discloses a clearance measuring tool between generator stator iron core and rotor magnetic pole, it is inconvenient to have solved the use that current measuring instrument exists, problem that measurement accuracy is low. Include in intraductal be provided with negative thread (4) of the right -hand member of long tube (1), be in the same place at the lateral wall of a measurement section of thick bamboo (5) and the right -hand member face fixed connection of long tube (1), it communicates together through through -hole (8) on it hole with long tube (1) to measure a section of thick bamboo (5), the bottom is provided with pressure spring (6) in measuring a section of thick bamboo (5), it has movement measuring staff (7) to peg graft in the hole of a measurement section of thick bamboo (5) above pressure spring (6), head at ejector pin (2) is provided with the pin thread, the head of ejector pin (2) passes the negative thread spiro union of the intraductal setting of right -hand member of long tube (1) back and long tube (1) along direction from left to right, the head of ejector pin (2) and the side of movement measuring staff (7) activity apical grafting. The utility model has the characteristics of easily operation and measurement accuracy are higher.
Description
Technical field
The utility model relates to a kind of clearance measurement utensil, particularly a kind of survey instrument measuring gap between stator core in generator and rotor magnetic pole.
Background technology
In the assembling process of generator, will adjust the gap between stator core and rotor magnetic pole, whole adjustment carries out according to when Measurement accuracy to the air gap in generator.Existing measuring method be by vapour in generator, whether the gap position of encouraging two ends gap-gas segregating ring directly carries out clearance between measurement stator and rotor even, measurement adopts Special air gap measurer to measure, this specific purpose tool is by measuring extension rod and measuring head forms, measuring head is screwed onto the end of extension rod, composition L shape measuring appliance.During use, measuring head is reached in the measured gap in generator and predict, length due to each measuring head is fixing, wants Measurement accuracy space, just needs the measuring head constantly changing different length, until the length of measuring head and gap coincide, just gap length accurately can be obtained.It is inconvenient to there is use in this measuring appliance, the shortcoming that measuring accuracy is low.
Summary of the invention
The utility model provides clearance measurement tool between a kind of electricity generator stator core and rotor magnetic pole, solves the use inconvenience that existing measuring appliance exists, the technical matters that measuring accuracy is low.
The utility model solves above technical matters by the following technical programs:
Clearance measurement tool between a kind of electricity generator stator core and rotor magnetic pole, comprise long tube and measuring cylinder, female screw is provided with in the right-hand member pipe of long tube, be fixed together at the lateral wall of measuring cylinder and the right side of long tube, measuring cylinder is connected together by the endoporus of the through hole on it and long tube, measuring cylinder inner bottom part is provided with stage clip, movement measuring staff is plugged with in the endoporus of the measuring cylinder above stage clip, the head of push rod is provided with pin thread, the head of push rod is screwed together with the female screw that arranges in the right-hand member pipe of long tube along direction from left to right through after long tube, the head of push rod and the side of movement measuring staff are movably connected.
The afterbody of push rod is provided with handle.
It is simple that the utility model has structure, and cost is low, is easy to the feature operated and measuring accuracy is higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
Clearance measurement tool between a kind of electricity generator stator core and rotor magnetic pole, comprise long tube 1 and measuring cylinder 5, female screw 4 is provided with in the right-hand member pipe of long tube 1, be fixed together at the lateral wall of measuring cylinder 5 and the right side of long tube 1, measuring cylinder 5 is connected together with the endoporus of long tube 1 by the through hole 8 on it, measuring cylinder 5 inner bottom part is provided with stage clip 6, movement measuring staff 7 is plugged with in the endoporus of the measuring cylinder 5 above stage clip 6, the head of push rod 2 is provided with pin thread, the head of push rod 2 is screwed together along direction from left to right through the female screw arranged after long tube 1 and in the right-hand member pipe of long tube 1, the head of push rod 2 and the side of movement measuring staff 7 are movably connected.
The afterbody of push rod 2 is provided with handle 3.The utility model is applicable to the measurement of measuring clearance and other sheltered situation inside dimension between stator and rotor during all types of generator is installed, and also can be used for the measurement of the inner size gap such as process component middle slot, hole.
After measuring head stretches into surveying work place, movable measuring head is retracted by Compress Spring, then turning handle, make rotating shaft nose threads securing rod by the locked movable measuring head of pressure effect, take out survey instrument, measure this instrument measuring head front and back end distance size with outside micrometer, be gap, measuring point.
