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 the pneumatics field, relate in particular 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, and is annual with 20% speed increment.Its huge market demand, development prospect is wide.Oscillating cylinder is owing to unreasonable structure in the market, and general structure heaviness and angle modulation screw easily sever, swing simultaneously is freely not suitable, and the life-span is not long.
Summary of the invention
At above-mentioned technological deficiency, the technical problem that the present invention need solve provides 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 a telescopic cylinder of two stages structure, comprise that symmetry is located at the cylinder barrel of middle end cap both sides and piston, the cylinder end piece in the cylinder barrel, connect by tooth bar between the two-piston as piston rod, tooth bar passes across middle end cap, it also comprise in the vertical embedding end cap and with tooth bar meshed gears axle, described in end cap be aluminum alloy lid and integrated setting; Described gear shaft upper end is provided with the upper bearing (metal) gland with end cap in the gear shaft inclosure, and the upper bearing (metal) gland adopts with middle end cap and is threaded; Also be provided with angle modulation screw on the described end cap, angle modulation screw and piston are at same axial direction.
Further: in above-mentioned highly reliable oscillating cylinder, also be provided with the buffer ring that cushions and have non-return valve function as gas on the described end cap.Also be provided with the axis of guide bearing sleeve of regulating compensate for wear and guiding on the described tooth bar.
Compared with prior art, above-mentioned highly reliable oscillating cylinder, middle end cap aluminum alloy material, end cap is integrated, promptly eliminates old-fashioned lower bearing gland structure; The upper bearing (metal) gland adopts with middle end cap and is threaded, and eliminates the old-fashioned structure of passing through socket head screw fastener shaft pressure cap; Angle modulation screw is placed on the two end cap, with the same axial direction of piston, limited piston stroke, reaches the effect of regulating pendulum angle; The gas buffering of two end cap adopts the buffer ring that has non-return valve function; The guiding of tooth bar adopts can regulate the guide structure of compensate for wear.So the structure of above-mentioned oscillating cylinder is more reasonable and practical, conveniently use client's maintenance, improve the force-bearing situation of angle modulation screw, it is more reliable to work, and swings more smooth suitable, steady.The long service life of product.The throttle valve speed governing of above-mentioned oscillating cylinder, when piston rod is not creeped, minimum working pressure: 2bar; Lowest operation speed≤50mm/s; Operating life is no less than 4 years.
Description of drawings
Fig. 1 is an 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 a telescopic cylinder of two stages structure, comprise that symmetry is located at the cylinder barrel 2 of middle end cap 1 both sides and piston 3, the cylinder end piece 4 in the cylinder barrel, connect by tooth bar 5 between the two-piston 3 as piston rod, tooth bar 5 passes across middle end cap 1, it also comprise in the vertical embedding end cap 1 and with tooth bar 5 meshed gears axles 6, described in end cap 1 be aluminum alloy lid and integrated setting; Described gear shaft 6 upper ends are provided with the upper bearing (metal) gland 7 with end cap in the gear shaft inclosure, and upper bearing (metal) gland 7 adopts with middle end cap 1 and is threaded; Also be provided with angle modulation screw 8 on the described end cap 4, angle modulation screw 8 and piston 3 are at same axial direction.Also be provided with the buffer ring 9 that cushions and have non-return valve function as gas on the described end cap 4.Also be provided with the axis of guide bearing sleeve 10 of regulating compensate for wear and guiding on the described tooth bar 5.
Above-mentioned highly reliable oscillating cylinder, middle end cap 1 usefulness aluminum alloy material and integrated setting promptly eliminated 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 of passing through socket head screw fastener shaft pressure cap; Angle modulation screw 8 is placed on the two end cap 4, with piston 3 same axial directions, limited piston stroke, reaches the effect of regulating pendulum angle; The gas buffering of two end cap 4 adopts the buffer ring 9 that has non-return valve function; The guiding of tooth bar 5 adopts can regulate the guide structure of compensate for wear.So the structure of above-mentioned oscillating cylinder is more reasonable and practical, conveniently use client's maintenance, improve the force-bearing situation of angle modulation screw, it is more reliable to work, and swings more smooth suitable, steady.
The above is a preferred embodiment of the present invention, is not breaking away under the design situation of the present invention, carries out any conspicuous distortion and replacement, all belongs to protection scope of the present invention.
