Background technology
At present, vehicle-mounted brake cylinder form is a lot, especially spring energy-storage brake cylinder is widely used because it has good self-shield security performance, also just because its good self-shield performance is brought great difficulty and unsafe factor to maintenance, because spring energy-storage brake cylinder is a kind of car brakeing wheel cylinder of double cavity structure, ante-chamber is service brake chamber, back cavity is parking braking chamber, owing to having in back cavity by precompressed thick spring, maximum elastic force reaches more than 500 kilogram, abnormally dangerous during by pump housing breakdown maintenance while disassembling this brake cylinder, be easy to eject and hurt sb.'s feelings, and assembling difficulty.
Application number is the dismantling device that discloses a kind of brake pump in 201320101953.8 patent of invention, the support of this instrument is arranged on base, pushnut is arranged in the middle of the entablature of support, the external screw thread of screw rod and the internal thread rotation of pushnut and, brake cylinder, fixture are placed on support, and between brake cylinder, two perpendicular pin of fixture in support, fixture covers brake cylinder, hydraulic means is installed, on the upper surface of the lower end of screw rod in hydraulic means on brake cylinder. This instrument withstands brake cylinder by operation hydraulic means and rotary screw in use, the spring of brake cylinder can be able to fully be discharged, thereby complete dismounting or the assembling of brake cylinder, but in this instrument, the use of hydraulic means increases cost and has made use difficulty.
Summary of the invention
The object of the invention is to overcome the shortcoming existing in prior art, provide a kind of with low cost, the spring energy-storage brake cylinder obturator that result of use is good, this obturator has reduced tearing open of brake cylinder spring cavity, difficulty and unsafe factor in dress link, the technical scheme adopting is: a kind of spring energy-storage brake cylinder obturator, comprise support, rack-mount force application part and positioning clamping parts, it is characterized in that: described force application part comprises application of force leading screw, be fixed on the feed screw nut on support with application of force leading screw is used in conjunction with, lower end at application of force leading screw is welded with hollow sleeve, thrust bearing is equipped with in the lower end of hollow sleeve, spring energy-storage brake cylinder is contained between described thrust bearing and positioning clamping parts.
Technical characterictic of the present invention also has: described positioning clamping parts comprise the positioning seat being fixed on support, and described positioning seat coordinates with the lower surface of described spring energy-storage brake cylinder.
Technical characterictic of the present invention also has: described positioning seat is empty positioning seat in back taper, and in described back taper, empty positioning seat has the Internal hole positioning face of back taper.
Technical characterictic of the present invention also has: described support comprises upper backup pad and lower supporting plate, between upper backup pad and lower supporting plate, is fixed with support post, and described positioning seat is fixed on lower supporting plate.
Technical characterictic of the present invention also has: described feed screw nut is fixed on described upper backup pad.
Technical characterictic of the present invention also has: the diameter of bore of described thrust bearing and the aperture of hollow sleeve are all bigger than the spring cavity rod diameter of described brake cylinder.
Beneficial effect of the present invention is: the spring cavity of brake cylinder to be repaired is placed between thrust bearing and hollow sleeve, spring cavity push rod is just to application of force leading screw lower end, make it to move down by rotational lead screw and be pressed into spring cavity push rod, under pressure, spring separates with pump case upper end, thereby overcome the elastic force of spring action on pump case, now pull down pump case holding screw, slow circumvolve application of force leading screw makes it to move, spring force is progressively discharged, until after disappearing completely, take off the parts such as back cavity piston, spring; The accurate positioning of this obturator, reliability are high, and the support of frame-type had both been conducive to the operation such as dismounting and adjustment of brake cylinder, hurt sb.'s feelings by avoiding parts to eject; Back taper positioning seat can effectively prevent pump housing sidesway; Application of force leading screw, as the force application means that overcomes spring force, can be adjusted the dynamics of exerting pressure flexibly; The use of thrust bearing has reduced leading screw rotary resistance, makes flexible operation light. The present invention's safety, reliable, use facility flexibly, with low cost.
