Description
(1) technical field:
The directed holding mechanism of lever type pneumatic pressurizing cradle belongs to textile machine.
(2) background technology
The holding mechanism that existing lever type pneumatic pressurizing cradle is installed, be to adopt former and later two tangential screws to connect installation deck that upper and lower two halves separate and reel cage is anchored on to grip on the pipe, insert the initial angular position that the locating hole that grips on the pipe is determined reel cage with being loaded on down the locating piece of installing on the deck, use former and later two screws to regulate the angular position that deck is installed again, to adjust the reel cage plus-pressure in the mode of " tight at first but afterwards loose " or " loose at first but afterwards tight ".The shortcoming that it exists is: 1. have excessive control gap because the upper and lower two halves of reel cage are installed between the deck end face, in reel cage installation, pressure regulation and fastening process, inconsistent because of front and back screw precession length, reel cage can be along gripping tube hub rotation, the uncontrollable unanimity of angular position; 2. for adjusting the rated operating pressure of reel cage, during fastening forward and backward screw, the dynamics of tightening is all inconsistent usually, and the upper and lower installation deck of reel cage is out of shape because of excessive load, causes the lever type pneumatic pressurizing cradle installation procedure loaded down with trivial details, adjustment rated pressure difficulty.
To three installations that list roller bearing, be to adopt to be installed in respectively to adjust on seat, the groove seat, combine by bearing block, jump ring and supporting pad three groups decks are installed and respectively three axle journals that list roller bearing are carried out orientation and grip and support.The three staff gauge reticle contrapositions of then leaning on visual bearing block, adjusting on seat and the housing of spacing that list roller bearing are adjusted.The shortcoming that it exists is: 1. because jump ring hardness is irregular, yielding, fracture, can't lists roller bearing to three and implement safe and reliable gripping; 2. supporting pad supports the supporting mooring points of upper roller bearing axle journal, and the wearing and tearing of the strong point directly influence the stressed stability of reel cage; 3. the bearing block positioning and guiding has reduced and has guaranteed that reel cage lists the reliability that the three-way depth of parallelism of roller bearing requires to three apart from weak point; 4. the staff gauge reticle spacing on bearing block, the adjustment seat is big, and the scale on the groove seat is installed easily crooked, has reduced visual adjusting three and has listed the accuracy that roller bearing spaces.
(3) summary of the invention
Problem to be solved in the utility model is to provide a kind of can improve lever type pneumatic pressurizing cradle angular position installation accuracy and can improve its three directed holding mechanism that lists the three-way parallel accuracy of roller bearing at above deficiency.Its technical scheme is as follows:
The utility model comprises upper and lower installation deck, and before, during and after the bearing deck, on deck is installed is enclosed within and grips on the pipe, and connect with the reel cage housing, under deck be installed connected with last installation deck, under install locating piece arranged on the deck, locating piece inserts the locating hole that grips on the pipe.On the reel cage housing, be equipped with and adjust seat and groove seat, on the adjustment seat, fore bearing deck, middle (center) bearing deck and spring of top apron cradle are housed, rear bearing deck and scale are housed on the groove seat.Its key technology is at last installation deck front end hinge seat to be installed, and hinge axis is housed on the hinge seat, on the deck rear end is installed nut is housed, the front end of upper and lower installation deck is hinged by hinge axis, the rear end is connected with nut with a screw for closed mouthful.Fore bearing deck and rear bearing deck have big spacing guiding slot port in the left and right sides that grips jaw, the back claw middle part that the fore bearing deck grips jaw disconnects, the preceding claw middle part that the middle (center) bearing deck grips jaw disconnects, and fore bearing deck, middle (center) bearing deck, rear bearing deck jaw inner chamber have the cylindrical profile isometrical with the roller bearing axle journal.
Compared with prior art the utlity model has following beneficial effect:
1, reel cage angular position installation accuracy is improved, and guarantees the unanimity of reel cage installation angular position.Easy for installation, reliable and stable, greatly reduce installation labour intensity.
2, the reel cage installation is fastening separates with the program of pressure regulation, has simplified the pressure regulation program, thoroughly solves the disadvantage of lever type pneumatic pressurizing cradle pressure regulation difficulty.
3, reel cage requires to have obtained stable raising to the three three-way parallel accuracy that list roller bearing.
4, bearing installation deck supports safe and reliable to the three elasticity gripping and the faces of cylinder that list roller bearing.
5, visual adjustment three lists roller bearing and spaces easy to operate, accurate.
