Abstract
The invention discloses a high-reliability oscillating cylinder, which has a two-stage telescopic cylinder structure. The high-reliability oscillating cylinder comprises cylinders symmetrically arranged on two sides of a middle end cover, and pistons and cylinder end covers arranged in the cylinders, wherein the two pistons are connected with each other through a rack serving as a piston rod, and the rack passes across the middle end cover. The high-reliability oscillating cylinder also comprises a gear shaft which is vertically embedded in the middle end cover and is meshed with the rack; the middle end cover is an aluminum alloy cover and is integrally arranged; the upper end of the gear shaft is provided with an upper bearing gland to seal the gear shaft into the middle end cover, and the upper bearing gland is connected with the middle end cover through threads; and the end covers are provided with angle adjusting screws which are arranged in the same axial direction with the pistons. The high-reliability oscillating cylinder is more reasonable and practical in structure, is convenient to maintain by using customers, improves the stress condition of the angle adjusting screws, and is more reliable in work and more smooth and steady in oscillating, and the service life of a product is longer.
Description
Technical field
The invention belongs to pneumatics field, particularly relate to a kind of highly reliable oscillating cylinder.
Background technique
Along with the raising of industrial automation level, China's pneumatic industry obtained swift and violent development at nearly 15 years, every year with 20% speed increment.Its huge market demand, development prospect is wide.Oscillating cylinder is due to unreasonable structure in the market, and general structure is heavy and angle modulation screw easily severs, swing not smoothly simultaneously, and the life-span is not long.
Summary of the invention
For above-mentioned technological deficiency, the technical problem that the present invention need solve is to provide a kind of highly reliable oscillating cylinder.
The technical problem that the present invention need solve is achieved through the following technical solutions: a kind of highly reliable oscillating cylinder, it is telescopic cylinder of two stages structure, comprise symmetry and be located at piston, cylinder end piece in the cylinder barrel of middle end cap both sides and cylinder barrel, connected by the tooth bar as piston rod between two-piston, tooth bar passes across middle end cap, it also comprise end cap in vertical embedding and with tooth bar meshed gears axle, described middle end cap is aluminum alloy lid and integrated setting; The upper bearing (metal) gland of end cap during described gear shaft upper end is provided with and is enclosed by gear shaft, upper bearing (metal) gland adopts with middle end cap and is threaded; Described end cap is also provided with angle modulation screw, and angle modulation screw and piston are at same axial direction.
Further: in above-mentioned highly reliable oscillating cylinder, described end cap to be also provided with as gas buffering and with the buffer ring of non-return valve function.Described tooth bar is also provided with and regulates compensate for wear and the axis of guide bearing sleeve of guiding.
Compared with prior art, above-mentioned highly reliable oscillating cylinder, middle end cap aluminum alloy material, end cap integration, namely eliminates old-fashioned lower bearing gland structure; Upper bearing (metal) gland adopts with middle end cap and is threaded, and eliminates the old-fashioned structure by socket head screw fastener shaft pressure cap; Angle modulation screw is placed in two end cap, axial direction same as piston, limited piston stroke, reaches the effect regulating pendulum angle; The gas buffering of two end cap adopts the buffer ring with non-return valve function; The guiding of tooth bar adopts the guide structure that can regulate compensate for wear.So the structure of above-mentioned oscillating cylinder is more reasonable and practical, the maintenance of client easy to use, improves the force-bearing situation of angle modulation screw, and work is more reliable, swings more smoothly, steadily.The long service life of product.The speed governing of above-mentioned oscillating cylinder throttle valve, when piston rod is not creeped, minimum use pressure: 2bar; Lowest operation speed≤50mm/s; Operating life is no less than 4 years.
Accompanying drawing explanation
Fig. 1 is oscillating cylinder explosive view of the present invention; Wherein end cap, 2 cylinder barrels, 3 pistons, 4 end caps, 5 tooth bars, 6 gear shafts, 7 upper bearing (metal) glands, 8 angle modulation screws, 9 buffer rings, 10 axis of guide bearing sleeves in 1.
Specific embodiments
With reference to accompanying drawing 1 and embodiment, the present invention is described.
A kind of highly reliable oscillating cylinder, it is telescopic cylinder of two stages structure, comprise symmetry and be located at piston 3, cylinder end piece 4 in the cylinder barrel 2 of middle end cap 1 both sides and cylinder barrel, connected by the tooth bar 5 as piston rod between two-piston 3, tooth bar 5 passes across middle end cap 1, it also comprise end cap 1 in vertical embedding and with tooth bar 5 meshed gears axle 6, described middle end cap 1 is aluminum alloy lid and integrated setting; The upper bearing (metal) gland 7 of end cap during described gear shaft 6 upper end is provided with and is enclosed by gear shaft, upper bearing (metal) gland 7 adopts with middle end cap 1 and is threaded; Described end cap 4 is also provided with angle modulation screw 8, and angle modulation screw 8 and piston 3 are at same axial direction.Described end cap 4 to be also provided with as gas buffering and with the buffer ring 9 of non-return valve function.Described tooth bar 5 is also provided with and regulates compensate for wear and the axis of guide bearing sleeve 10 of guiding.
Above-mentioned highly reliable oscillating cylinder, middle end cap 1 uses aluminum alloy material and integrated setting, namely eliminates old-fashioned lower bearing gland structure; Upper bearing (metal) gland 7 adopts with middle end cap 1 and is threaded, and eliminates the old-fashioned structure by socket head screw fastener shaft pressure cap; Angle modulation screw 8 is placed in two end cap 4, axial direction same as piston 3, limited piston stroke, reaches the effect regulating pendulum angle; The gas buffering of two end cap 4 adopts the buffer ring 9 with non-return valve function; The guiding of tooth bar 5 adopts the guide structure that can regulate compensate for wear.So the structure of above-mentioned oscillating cylinder is more reasonable and practical, the maintenance of client easy to use, improves the force-bearing situation of angle modulation screw, and work is more reliable, swings more smoothly, steadily.
The above is a preferred embodiment of the present invention, is not departing from design situation of the present invention, is carrying out any apparent distortion and replacement, all belong to protection scope of the present invention.
