The assembly technology clamp realizes the boring of the inner-ring axle hole and the outer-ring axle hole of the guide vane in-step, the machining precision is high, the large scale equipment is not occupied, the investment is small, and the universality is wide.
Description
Technical field
The utility model relates to a kind of axis hole machining tool fixture, more specifically to a kind of tubular stator inner and outer rings axis hole machining tool fixture.
Background technology
In axle extend through flow type hydraulic turbine, unit overcurrent part water distributor is made up of parts such as ring, stator outer shroud, gate linkage, control loop, servomotor in 16 stators, the stator.Stator is contained between the interior ring of stator, the stator outer shroud, and hydraulic turbine inflow-rate of water turbine is regulated and emergency shutdown is mainly realized by regulating guide vane opening.Accept to distribute the oil pressure that comes when servomotor after from governing system, the just size of adjustable guide blade aperture.Therefore, require the rotation of stator flexibly necessary.In the unit design, the axis hole of the interior ring of stator, stator outer shroud is concentric, and ring, outer shroud center line and axis hole center line are 65 ° of angles in the stator, and this will encircle in the differentiate leaf, the outer shroud axis hole must be processed with cutter, can guarantee with one heart.In the prior art, be not exclusively used in tubular stator inner and outer rings axis hole machining tool fixture, realize that ring in the stator, outer shroud axis hole must carry out with cutter processing in main equipment, therefore investment is big, and versatility is little.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of simple in structure, small investment, the tubular stator inner and outer rings axis hole machining tool fixture that versatility is good.
The purpose of this utility model is achieved by following technical scheme:
A kind of tubular stator inner and outer rings axis hole machining tool fixture, comprise bearing, basis, swivel bearing dish, slide block, positioning clamping fixture, mark post, boring bar, sloping platform, boring head and slide unit, design an endoporus in swivel bearing disk center bearing is installed, simultaneously design has slide block, supporting disk to be designed to a seam to cooperate with the positioning clamping fixture cylindrical on supporting disk.In the positioning clamping fixture centre bottom, design a boss, be bearing on the bearing of swivel bearing dish, the positioning clamping fixture height is determined by supporting disk, interior ring, outer shroud.Positioning clamping fixture chassis external diameter is determined by stator outer shroud small end flange outer diameter and seam position.There is calibration to measure piece in the design of cylindrical place, positioning clamping fixture chassis, the swivel bearing dish vertically is contained on the basis, according to positioning clamping fixture height design mark post and the sloping platform that is 25 ° of inclination angles, mark post vertically is contained on the positioning clamping fixture, boring head and slide unit are installed on the sloping platform, boring bar is contained on boring head and the slide unit, the axis alignment mark post of boring bar top.In the bore hole process, longer because of boring bar, easily produce vibration, cause machining accuracy can not reach requirement to axis hole, even have oval phenomenon, for this reason, design a boring bar carriage and a support plate, hold boring bar, solve the boring bar vibration problem, so machining accuracy is higher.
This frock clamp is simple to operate, the machining accuracy height, and practicality is good; In the axle extend through flow type hydraulic turbine stator of each model specification of processing ring, during the outer shroud axis hole, only need to adjust supporting disk and positioning clamping fixture chassis external diameter gets final product, versatility is good.
The processing technology scheme is as follows:
1, the lifting workpiece is adjusted the calibration piece, makes calibration evenly also fixing, compresses positioning clamping fixture, mounting support plate and carriage.
2, process first group of axis hole, after processing by drawing, unclamp positioning clamping fixture, after being rotated in place according to calibration piece position, compress positioning clamping fixture, corresponding mounting support plate and carriage are pressed second group of axis hole of figure paper conversion;
3, according to last step, process the back successively and respectively organize axis hole.
The beneficial effects of the utility model are the same boring processing that has realized ring, outer shroud axis hole in the stator, and the machining accuracy height does not take main equipment, small investment, and versatility is big.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure 1, bearing; 2, basis; 3, swivel bearing dish; 4, slide block; 5, positioning clamping fixture; 6, stator outer shroud; 7, ring in the stator; 8, mark post; 9, support plate; 10, carriage; 11, boring bar; 12, boring head and slide unit; 13 sloping platforms.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Among the figure, in the tubular stator, outer shroud axis hole machining tool fixture comprises bearing, the basis, the swivel bearing dish, slide block, positioning clamping fixture, mark post, boring bar, sloping platform, carriage, support plate, boring head and slide unit part, ring in the stator, outer shroud in unit assembling large end face at same horizontal plane, ring in the stator, the outer shroud center is at same axis, design an endoporus in swivel bearing disk center bearing is installed, design has slide block on supporting disk simultaneously, supporting disk is designed to a seam and cooperates with the positioning clamping fixture cylindrical, in the positioning clamping fixture centre bottom, design a boss, be bearing on the bearing of swivel bearing dish, like this, it is little that positioning clamping fixture rotates resistance, and can displacement in rotary course.The positioning clamping fixture height is determined by supporting disk, interior ring, outer shroud, and the interior ring of stator, outer shroud are fixed on the mold, and positioning clamping fixture chassis external diameter is determined that by stator outer shroud small end flange outer diameter and seam position the design calibration is measured piece at cylindrical place, positioning clamping fixture chassis.The swivel bearing dish vertically is contained on the basis, design a mark post and the sloping platform that is 25 ° of inclination angles according to the positioning clamping fixture height, mark post vertically is contained on the positioning clamping fixture, and boring head and slide unit are installed on the sloping platform, boring bar is contained on boring head and the slide unit, the axis alignment mark post of boring bar top.
In the bore hole process, longer because of boring bar, easily produce vibration, cause machining accuracy can not reach requirement, even have oval phenomenon axis hole, for this reason, design a boring bar carriage and a support plate, hold boring bar, solve the boring bar vibration problem.
This frock clamp is simple to operate, the machining accuracy height, and practicality is good; In the axle extend through flow type hydraulic turbine stator of each model specification of processing ring, during the outer shroud axis hole, only need to adjust supporting disk and positioning clamping fixture chassis external diameter gets final product, versatility is good.
