Description
One, technical field
The utility model belongs to the textile machine member, particularly a kind of pneumatic pressurizing cradle.
Two, background technology
Pneumatic pressurizing cradle is the application of pneumatic pressurization technology at field of textiles, and it is stable that it has plus-pressure, and elastic force does not have decline, can realize advantages such as collective's pressure regulation, half release of pressure, is applicable to the various drafting systems of spinning machine.Pneumatic pressurizing cradle mainly by pressure exerting arrangement, bearing rocker arm body, preceding in leverage, middle back leverage, block down and gripping pipe that air bag and pressure transmission part be housed constitutes.Wherein, pressure exerting arrangement, bearing rocker arm body, preceding middle leverage and middle back leverage are formed the reel cage main body.In the reel cage main body, lever in preceding in the leverage---adjust the structure of seat and the performance that the accuracy of manufacture directly influences drafting system, especially top roller is to the depth of parallelism of bottom roll in the drawing plane direction, simultaneously, also have influence on precision and interchangeability that pneumatic pressurizing cradle distributes power, so this member is most important.
The disclosed compensating error formula of Chinese patent ZL97210380.5 reel cage guarantees the depth of parallelism of bottom roll in the drawing plane direction by compensation arrangement is set, thereby suitably reduces the accuracy of manufacture of forming each member of reel cage, to reduce production costs.So-called error-compensating apparatus, be with former be that holistic short lever (adjust seat) is decomposed into short lever (upper pedestal) and following short lever (lower base) manufacturing, to go up short lever (upper pedestal), short lever (lower base), preceding gripping pawl (preceding little seat), middle gripping pawl (the little seat in back) connection (this belongs to dress just) down with screw, after finishing the error compensation of adjusting each member of realization on the adjustment instrument, will go up short lever (upper pedestal), following short lever (lower base) and preceding gripping pawl (preceding little seat) soldering again and be integral.Though this technical scheme can make bottom roll reach requirement and reduce the machining accuracy of each member in the depth of parallelism of drawing plane direction, has the following disadvantages: 1, combination comprise just dress, adjust, welding, operation is various; 2, the last location of each member is determined by the specific adjusted instrument that is fit to certain spinning machine, and preceding gripping pawl (preceding little seat) links to each other with following short lever (lower base) by welding, thereby can't adjust and lack interchangeability; 3, upward the contact-making surface of the structure of short lever (upper pedestal) and long lever is bigger, influences the precision of distribution power; 4, adopt soldering, structural strength is low.
Three, summary of the invention
The utility model provides a kind of new construction pneumatic pressurizing cradle at the deficiency that prior art exists, and this kind reel cage had both had high service precision, had interchangeability again, and can simplify production process.
The technical solution of the utility model is: the structure and the compound mode of exchanging bed rearrangement are improved.Adjusting seat is combined by upper pedestal and lower base, symmetrical centre at upper and lower pedestal is provided with the location structure that guarantees the combination precision, during combination, positional precision by location structure control upper pedestal and lower base left and right directions, adjust the perpendicularity of upper and lower each corresponding aperture of pedestal by anchor clamps, after being seated, adopt welding manner that they are linked into an integrated entity, adopt spot welding during welding, to improve structural strength.
In order further to improve service precision, the technical scheme of employing is at the upper pedestal two lug arranged outside boss of adjusting seat.
In order further to improve interchangeability, the lower base of adjusting seat is designed to the slot type guide rail structure, and the size of the size of guide-track groove and little seat is complementary, and the little seat that is positioned at guide-track groove is fixed by screw, unclamping screw can move along guide-track groove, to adjust the installation site as required.
For the adjustment with little seat installation site matches, adjust seat lower base lateral surface and be provided with gage mark, in order to measure the distance that little seat moves.
The utility model is compared with existing pneumatic pressurizing cradle, has following beneficial effect:
1. adjust the location structure that passes through himself when the upper and lower pedestal of seat makes up and guarantee assembly precision, can not only satisfy design accuracy and depth of parallelism requirement, and improve service precision and interchangeability, simplified clustered operation, saved special-purpose adjustment instrument.
2. the boss of adjusting seat upper pedestal two lug arranged outside can reduce the contact-making surface of adjusting seat and groove seat, thus the precision of raising distribution power.
3. little seat with adjust seat for ease of being threaded of dismounting, can adjust little installation site according to the requirement of different spinning machines, further improved interchangeability.
4. the lower base arranged outside has gage mark, is convenient to control the amount of movement that little seat moves along guide-track groove.
5. change rear leather roller seat just applicable to V-arrangement drawing-off and plane drawing-off, have advantage of wide range of application.
6. spot welding is adopted in welding, has improved structural strength.
