Abstract

The utility model discloses a nitrogen balance cylinder, including shell, front end housing, rear end cap and inside piston rod, the end was connected with the connector before the piston rod front end stretched out just from the front end housing, thereby the diameter of piston rod be lighter than behind the piston of internal diameter and the piston rod of shell end surface and the contact of shell inner wall form a length along with the piston rod motion the closed nitrogen gas chamber of change, it imports and exports nitrogen gas chamber and outside intercommunication and shows at nitrogen gas exit department setting pressure to set up nitrogen gas on the shell first half wall. The utility model discloses use with drive machine and reduction gear cooperation, can realize very conveniently that pressure is invariable to equilibrium stability of each action when effectively promoting the manual work of pile up neatly machine and doing is an elastomeric element who has good flexible performance.

Description

A kind of nitrogen balance cylinder

Technical field

This utility model is related to a kind of nitrogen balance cylinder, supports the use with intelligent heavy-load robot, is particularly well-suited to case class With building materials, walling, brick and tile.

Background technology

Robot palletizer be used in industrial processes execution high-volume workpiece, the crawl of package, carrying, piling, One class industrial robot of the tasks such as destacking, be integrate electromechanics, information, intellectual technology, computer science subject high-new Electronic product.With the continuous development of robot of China industry, technology and research field have reached certain level, robot palletizer Technical merit is also developed rapidly.

But current robot palletizer is substantially all does not install compensating cylinder or metal elastic between armstand and revolving bed The common elastic assembly such as spring, is simply provided with driving motor and decelerator, and the stability of equilibrium when completing each action seems not Enough.

Utility model content

Goal of the invention of the present utility model is：For above-mentioned problem, provide a kind of nitrogen balance cylinder, for code Between the armstand of buttress robot and revolving bed, use cooperatively with driving motor and decelerator, can effectively lift robot palletizer work The stability of equilibrium of each action when making.

The technical solution adopted in the utility model is such：

A kind of nitrogen balance cylinder, including the piston rod of shell, drive end bearing bracket, rear end cap and inside, piston rod front end is in the past End cap stretches out and front end is connected with union joint, and described diameter of piston rod is less than the internal diameter of shell and the piston rear end head of piston rod Outer surface is contacted with outer casing inner wall thus forming the closing nitrogen chamber that a length changes with piston rod movement, before described shell Import and export of nitrogen is opened up on half portion wall pressure gauge is installed by nitrogen chamber and ft connection and at import and export of nitrogen.

Technique scheme with high pressure nitrogen as working media, whole compensating cylinder has that small volume, elastic force is big, stroke length, Stable working, manufacture precision, long service life（About 1,000,000 times）, the gentle feature of spring curve.

Piston rear end head position phase preferably, being also fixedly connected cushion pad on described rear end cap inwall, with piston rod Correspond to enter row buffering.Cushion pad can avoid piston rod that rear end cap is impacted, thus effectively increasing the service life.

Preferably, being respectively provided with an installing hole and lifting hanger in left and right sides on described outer shell outer wall.Lifting hanger For, in transport of the present utility model and installation process, installing hole is used for for this utility model being arranged on robot palletizer.

In sum, due to employing technique scheme, this utility model is used cooperatively with driving motor and decelerator, Can easily realize that pressure is constant, thus effectively the work of lifting robot palletizer when each action stability of equilibrium, be one Plant the elastomeric element with good flexibility performance.

Fig. 2 is perspective view of the present utility model.

In figure labelling：1 is shell, and 2 is drive end bearing bracket, and 3 is rear end cap, and 4 is union joint, and 5 is piston rod, and 6 is piston rear end Head, 7 is cushion pad, and 8 is nitrogen chamber, and 9 is import and export of nitrogen, and 10 is pressure gauge, and 11 is installing hole, and 12 is lifting hanger.

Specific embodiment

Below in conjunction with the accompanying drawings, this utility model is described in detail.

Embodiment：

As Fig. 1, a kind of nitrogen balance cylinder, including the piston rod 5 of shell 1, drive end bearing bracket 2, rear end cap 3 and inside, piston Bar 5 front end is stretched out from drive end bearing bracket 2 and front end is connected with union joint 4, and described piston rod 5 diameter is less than internal diameter and the work of shell 1 Piston rear end head 6 outer surface of stopper rod 5 and shell 1 contact internal walls move with piston rod 5 and change thus forming a length Closing nitrogen chamber 8, described shell 1 first half wall opens up import and export of nitrogen 9 by nitrogen chamber 8 with ft connection and in nitrogen turnover Pressure gauge 10 is installed at mouth 9.

Also be fixedly connected cushion pad 7 on described rear end cap 3 inwall, corresponding with piston rear end head 6 position of piston rod 5 with Enter row buffering.

It is respectively provided with an installing hole 11 and lifting hanger 12 in left and right sides, as shown in Figure 2 on described shell 1 outer wall.
