Description
Technical field
The present invention relates to oscillating cylinder field, particularly a kind of adjusting screw rod of piston type oscillating cylinder.
Background technique
Piston type oscillating cylinder is a kind of pneumatic apparatus utilizing the piston rod driver output axle of one or two cylinder to do reciprocating rotating motion within the scope of several angle, and it is widely used in the transposition of object, upset, classification, clamping, the opening and closing of valve and the arm action etc. of robot.The rotational angle range of the output shaft of existing piston type oscillating cylinder is determined by the stroke of piston rod, and the stroke of piston rod is controlled by the adjusting screw rod that is located along the same line with it.Existing piston type oscillating cylinder is provided separately for the adjusting screw rod of the stroke of regulating piston bar and the inlet hole of cylinder body, causes overall structure to compare dispersion, increase size, and install and use cumbersome.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of adjusting screw rod of piston type oscillating cylinder, thus the shortcoming that the inlet hole of the adjusting screw rod and cylinder body that overcome existing oscillating cylinder is provided separately.
For achieving the above object, the invention provides a kind of adjusting screw rod of piston type oscillating cylinder, wherein, described adjusting screw rod is provided with a through hole using the inlet hole as cylinder body, and described adjusting screw rod is provided with one and runs through its sidewall to extend to the air intake adjusting screw in described inlet hole, described air intake adjusting screw is for adjusting the openings of sizes of described inlet hole.
Preferably, in technique scheme, described adjusting screw rod one end be positioned at outside described cylinder body is provided with a square-shaped head, and described air intake adjusting screw is arranged on described head.
Preferably, in technique scheme, the end face that described adjusting screw rod is positioned at one end of described cylinder body is arranged with a cone shape hole corresponding with described inlet hole.
Compared with prior art, the present invention has following beneficial effect:
1, the present invention is arranged at the inlet hole of cylinder body on adjusting screw rod, can simplified structure, makes compact overall structure, and increases the installing space of external feed stream device.
2, the end face of one end that adjusting screw rod of the present invention extends in cylinder chamber is arranged with a cone shape hole, and it can lead to air-flow and spread, and to increase the area that uniform stream acts on the end of piston rod, makes piston rod movement more steady.
Accompanying drawing explanation
Fig. 1 is the perspective view of the adjusting screw rod according to inventive piston formula oscillating cylinder.
Fig. 2 is the structural representation be installed on according to the present invention on cylinder body.
Main Reference Numerals illustrates:
1-adjusting screw rod, 11-inlet hole, 12-air intake adjusting screw, 13-head; 2-cylinder body, 21-end cap; 3-piston rod; 4-output shaft, 41-gear.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 1 to Figure 2, a kind of embodiment according to the specific embodiment of the invention is: a kind of adjusting screw rod of piston type oscillating cylinder, as shown in Figure 1, adjusting screw rod 1 is provided with one and runs through the through hole at its two ends using the inlet hole 11 as cylinder body, and adjusting screw rod 1 being provided with the screw that runs through its sidewall, this screw is perpendicular to inlet hole 11 and communicate with inlet hole 11.Air intake adjusting screw 12 is screwed in screw, and the end of air intake adjusting screw 12 extends in inlet hole 11, is controlled the openings of sizes of inlet hole 11 by adjustment air intake adjusting screw 12 degree of depth be screwed in screw.Preferably, air intake adjusting screw 12 is sunk screw.
When adjusting screw rod 1 is installed on an oscillating cylinder, as shown in Figure 2, adjusting screw rod 1 is arranged on the end cap 21 of the cylinder body 2 of oscillating cylinder, and one end of adjusting screw rod 1 is positioned at outside, and its other end is positioned at cylinder body 1 and corresponding with piston rod 3.Preferably, adjusting screw rod 1 one end be positioned at outside cylinder body 2 is provided with a square-shaped head 13, and air intake adjusting screw 1 is arranged on one of them side of head.Can to be screwed into easily and flexibly or to back-out adjusting screw rod 1 by the head 13 of square spigot, so that the stroke of adjustment piston rod 3.Further preferably, as depicted in figs. 1 and 2, the end face that adjusting screw rod 1 is positioned at one end of cylinder body is arranged with a cone shape hole corresponding with inlet hole 11, and the axis of cone shape hole and the axis of inlet hole 11 are located along the same line.Cone shape hole can lead to air-flow and spread, to increase the area that uniform stream acts on the end of piston rod 3, with when promoting piston rod 3, enable the striking force of the gear 41 on piston rod 3 pairs of output shafts 4 even, reduce wear, and it is more steady that piston rod 3 is moved.
External feed stream device is connected with the inlet hole 11 of adjusting screw rod 1, and air inlet system is slided to promote piston rod 3 toward inflation in cylinder body 1 by the inlet hole 11 of adjusting screw rod 1, thus makes gear 41 drive output shaft 4 to rotate.The present invention is arranged at the inlet hole 11 of cylinder body 1 on adjusting screw rod 1, and it can simplified structure, makes compact overall structure, and increases the installing space of external feed stream device, easy to use.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
