Abstract
The utility model discloses a pneumatic brake for a welding material winding device, which comprises cylinders, pistons, a brake seat, a spring, bolts and the like, wherein the two cylinders are symmetrically fastened on the brake seat by the bolts; and the cylinders and the brake seat are sealed by sealing rings, and communicated through a gas circuit. The pistons are arranged in the cylinders; one end of the cylindrical spring is adhered on the pistons, and the other end is propped against a gland; the other side of the gland is adhered to a hole elastic collar; the elastic collar is arranged in a cylinder circular groove; and the spring plays the role of resetting the pistons. A hexagon bolt and a flat washer fasten brake pads on the end surfaces of the pistons. When driving wheels need to be braked, the compressed air pushes the two pistons at the same time through cylinder gas inlets, and the brake pads on the pistons press the wheels and stop the same from rotating, and then the spring resets the brake pads which are fixed on the pistons, and wait for the next time of braking. The double-cylinder brake for the welding material winding device adopts double-cylinder braking, has the advantages of compact structure, large braking force, balanced stress of braked pieces, and reduced additional load to the shaft and a bearing brought by braking.
Description
Technical field
The utility model belongs to the pneumatic braking device in the mechanical device.
Background technique
Break is the comparatively general device of application in machine equipments, and form has multiple.In pneumatic braking device in the past, no matter adopt the braking of common double cylinder is the application of force or the device of axial force distribution has all occupied bigger space radially to moving runner, and the installation of this pair of cylinder break is restricted under some small space condition.If adopt the radially application of force then make the wheel unbalance loading of single cylinder, wheel, axle stress by bending in this case, and bearing produced additional load; If adopt single cylinder under application of force situation radially, axle is subjected to the symmetrical cycle varying load, simultaneously bearing is produced additional load, therefore adopts the method for single cylinder all will reduce spool and life-span of bearing.Special propose is, for twining wlding or the employed braking device of wire rod, have two kinds of situations to need in time to stop, the one, when changing thread, the 2nd, when having the fracture of wire phenomenon to occur in winding process, it is quick to require to stop.But present braking equipment can't satisfy the requirement that the wlding winding process stops immediately.Designed based on this utility model that to have an axial dimension little, compact structure does not produce additional load to axle and bearing, and the big wlding wind of braking force has enlarged the application area of pneumatic braking device with two cylinder breaks.
Summary of the invention
The purpose of this utility model be a kind of compact structure is proposed, braking force is big, axial dimension is little, axle and bearing are not produced two cylinder breaks of additional load, is applied to the braking device of wlding wind and other mechanical braking.
Structural principle of the present utility model is shown in accompanying drawing 1,2.The wlding wind comprises with two cylinder breaks: compositions such as piston y-type seal ring 1, cylindrical spring 2, plain washer 3, hexagon head bolt 4, piston 5, circlip for hole 6, bolt 7, O RunddichtringO 8, cylinder body 9, brake mount 10, gland 12, brake block 13.Two cylinder body 9 usefulness bolts 7 symmetries are anchored on the brake mount 10, have gas circuit 11 to communicate between two cylinder bodies 9 and brake mount 10, seal with O RunddichtringO 8 between cylinder body 9 and the brake mount 10 simultaneously.Cylinder body (right-hand member as shown) in two cylinder bodies is provided with a suction port 14.Piston 5 is loaded in the cylinder body 9, seals with y-type seal ring 1 between piston 5 and cylinder body 9.Cylindrical spring 2 one ends are affixed on piston 5, and the other end withstands gland 12, i.e. 5 reset responses of 2 pairs of pistons of cylindrical spring.Circlip for hole 6 is loaded in cylinder body 9 circular grooves, and the opposite side of gland 12 is close to circlip for hole 6, plays position-limiting action for gland 12 at this circlip for hole 6.Hexagon head bolt 4 and plain washer 3 are anchored on brake block 13 on the end face of piston 5.The spiral shell tail of hexagon head bolt 4 all is screwed in the piston 5, and hexagon head bolt 4 radially, axially all leaves the gap with brake block 13, and this is the locking measure of hexagon head bolt 4.
Description of drawings
Fig. 1 is the main pseudosection of wlding wind with two cylinder breaks, and figure low order end arrow is an inlet end.
Fig. 2 is the right elevation of Fig. 1.
Embodiment
During installation, at first single cylinder is assembled, y-type seal ring 1 is installed in piston 5 grooves, with gland 12 spring 2 is pressed in the piston 5 then.With the above-mentioned parts cylinder body 9 of packing into, compress, circlip for hole 6 is installed on cylinder body 9 then.Uniform three sulculuses of cylinder body 9 open ends are opened a technology groove on the piston 5, for brake block 13 usefulness are installed.With piston 5 gland 12 end faces of emerging, pass the brake block center hole with bolt 4 covers one plain washer 3 and be screwed into piston 5, bolt 4 spiral shell tails all are screwed in the piston 5.This moment, single cylinder assembling finished.Finish when two cylinders all assemble, seal ring 8 is put into cylinder body 9 grooves, two cylinders are connected on the brake mount 10 with bolt 7.Tracheae is inserted the suction port 14 (arrow shown in Figure 1) of right-hand member cylinder, get final product work.
The working procedure of break is as follows: when prime mover pass stopping time of wheels 15 rotations, solenoid valve is opened, pressurized air enters cylinder interior from cylinder body suction port 14, pressurized air promotes two pistons simultaneously, piston 5 holddown springs 2, the piston 5 end faces gland 12 of emerging simultaneously, the brake block 13 that is fixed on the piston 5 is pressed to wheel 15, wheel 15 is stopped operating, thereby reach the purpose of braking.Work as closed electromagnetic valve, pressurized air discharges, and cylindrical spring 2 promotes piston 5, the piston end surface withdrawal, and the brake block that is fixed on the piston resets, and waits for braking next time.
The effect that the utility model is useful is, adopts two cylinder brakings, compact conformation, and brake force is big, and braked part is subjected to Dynamic balance has reduced axle and bearing because the additional load that braking brings.
