Abstract
The utility model relates to an anti-falling cylinder which comprises a cylinder body, a cylinder piston, a cylinder front cover, a cylinder rear cover, a front cylinder rod, a rear cylinder rod, a spring and an overflow copper head. The cylinder front cover and the cylinder rear cover are fixed to the cylinder body respectively. One end of the front cylinder rod passes through the cylinder front cover and the cylinder body to form a retractable structure, and the other end thereof passes through the spring and the cylinder piston in sequence and then is connected with the rear cylinder rod. The rear cylinder rod passes through the cylinder rear cover and the cylinder body to form a retractable structure. The overflow copper head is arranged on the cylinder body. The anti-falling cylinder is connected with a gas source through the overflow copper head. The front cylinder rod is driven by the cylinder piston to extend and retract. When the gas source is cut off, the front cylinder rod completely extends out of the cylinder front cover to prevent the mechanical arm from falling. The anti-falling cylinder has simple structure and low cost, and can prevent the mechanical arm from falling freely when the gas pressure or the power source is suddenly cut off during the operation of the mechanical arm, thereby preventing the damage to humans, arms and dies.
Description
Technical field
The utility model relates to cylinder class device, for a kind of in, under the situation in large-scale manipulator sudden power source or the source of dying when the proper functioning, prevent manipulator fall to the damaging anti-fall cylinder of injection machine mould.
Background technique
Get in the thing process at the automated machine arm, break air pressure or power supply at work and do not have the problem that control is fallen in order to solve manipulator suddenly, once adopted some cylinders to control, but because of not being the special-purpose anti-fall cylinder of mechanism hand,, be unfavorable for the competition in market so thereby the too high complete machine cost that causes of cost is higher.How designing the anti-fall cylinder of a kind of special manipulator simple in structure, with low cost and reduce cost, is the starting point that we carry out the utility model design.
Summary of the invention
Problem to be solved in the utility model is: in, under the situation in large-scale manipulator sudden power source or the source of dying when proper functioning, the manipulator whereabouts injection machine mould of can damaging needs a kind of equipment simple in structure, with low cost prevent that manipulator from falling.
The technical solution of the utility model is: anti-fall cylinder, comprise cylinder body, cylinder piston, the cylinder protecgulum, cylinder back cover, the front air cylinder bar, rear cylinder bar, spring, piston packing, axle is used y-type seal ring, O RunddichtringO, 2 dry type bearings, hole back-up ring and excessive gas copperhead, cylinder protecgulum, cylinder back cover are fixed with back-up ring and cylinder body by the hole respectively, and 2 dry type bearings are pressed in respectively in cylinder protecgulum and the cylinder back cover, piston packing is arranged on the cylinder piston, axle is arranged in the cylinder protecgulum with y-type seal ring, and the O RunddichtringO is located in the cylinder protecgulum draw-in groove, and front air cylinder bar one end passes the cylinder protecgulum and cylinder body constitutes shrinking structure, the other end passes through spring successively, cylinder piston is connected with the rear cylinder bar, the rear cylinder bar passes cylinder back cover and cylinder body and constitutes shrinking structure, and the gas copperhead that overflows is arranged on the cylinder body, the residing spatial communication of rear cylinder bar in two spaces telling in cylinder body with cylinder piston.
Anti-fall cylinder connects source of the gas by the gas copperhead that overflows, and drives the flexible of front air cylinder bar by cylinder piston, and when source of the gas interrupts suddenly, the front air cylinder bar stretches out the cylinder protecgulum fully, stops the whereabouts of manipulator.
The end that the utility model rear cylinder bar stretches out cylinder is provided with through hole, connects a draw ring by through hole.When test-run a machine, manually can spur anti-fall cylinder rear cylinder bar like this, and then drive in the front air cylinder bar withdrawal cylinder body, allow about the manipulator freedom.The anti-fall cylinder of tradition is connected with the rear cylinder bar by a copperhead, is being buckled on the copperhead by draw ring again, and the utility model structure draw ring directly is buckled on the rear cylinder bar, has saved this part of copperhead, and is easy for installation, not fragile.
The anti-fall air cylinder structure of the utility model is simple, with low cost, in the manipulator working procedure, if air pressure or power supply break suddenly, can prevent the free fall of arm, thereby avoid the people, arm, the damage of mould etc.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 (a) is the utility model work schematic representation (b).
Embodiment
As Fig. 1, the utility model is by φ 20 anti-fall cylinder bodies 1, φ 20 cylinder pistons 2, φ 20 cylinder protecgulums 3, φ 20 cylinder back covers 4, φ 8 front air cylinder bars 5, φ 8 rear cylinder bars 6, spring 7, φ 20 piston packings 8,8 of φ are with y-type seal ring 9, φ 19 * 1.8O RunddichtringO 10, cushion pad 11, φ 22 holes back-up ring 12,2 DU0806 dry type bearings 13, the gas copperhead 14 that overflows constitutes.Cylinder body is aluminium extruding cylinder body (bar groove, a circular groove structure; Anodising), cylinder piston is " A6061 " aluminium section bar (anodising), forward and backward cylinder head is the copper lid, adopt " solid Bearing Steel " forward and backward cylinder column, and do the bright chromium of plating and handle, spring is " spring steel " (Nickel Plating Treatment), adopts " NBR " piston packing, y-type seal ring, O RunddichtringO, overall structure is firm, and is corrosion-resistant.The following describes assembling of the present utility model.
Loose mail is assembled: 2 DU0806 dry type bearing 13 usefulness are presented a theatrical performance as the last item on a programme to be pressed into respectively in cylinder protecgulum 3 and the cylinder back cover 4.Piston packing 8 is loaded on the cylinder piston 2.Axle is packed in the cylinder protecgulum 3 with y-type seal ring 9, the O RunddichtringO is packed in the cylinder protecgulum draw-in groove.
The piston assembling: the cylinder protecgulum semi-finished product that will install penetrate front air cylinder bar 5, and front air cylinder bar 5 one ends are connected with rear cylinder bar 6 by cushion pad 11, cylinder piston 2.
