Abstract
The utility model relates to a pressurizing-type multi-position cylinder, which comprises a large cylinder chamber, a small cylinder chamber, a small piston, a large piston, a middle piston, a front rod and a vent rod, wherein one end of the front rod is fixedly connected with the middle piston in the small cylinder chamber, the other end of the front rod penetrates through a front cover, and an executing end is formed; a through air-inlet channel is drilled in the vent rod along the axis direction of the vent rod, one end of the vent rod extends into the small piston, an air-inlet cavity is formed between one end of the vent rod and the middle piston, and the other end of the vent rod is fixedly connected with the small piston in the large cylinder chamber; and a first air-inlet hole communicated with the inner part of the small cylinder chamber is drilled on the front cover, a fourth air-inlet hole communicated with the inner part of the large cylinder chamber is drilled on a middle cover, a second air-inlet hole and a third air-inlet hole are respectively drilled on a rear cover, the second air-inlet hole is communicated with the air-inlet channel in the vent rod through an air-inlet hole on the large piston, and the third air-inlet hole is communicated with an air-inlet gap. By integrating the structures of a pressurizing cylinder and a multi-position cylinder inside a cylinder and drilling a vent hole on the vent rod, the whole external structure is reduced, the use in a smaller space is realized, and the complicated mechanical action can be realized by combining the output difference of the large cylinder chamber and the small cylinder chamber.
Description
Technical field
This practicality relates to a kind of cylinder, relates in particular to a kind of boosting type multiposition cylinder.
Background technique
Existing cylinder is commonly used multiposition type cylinder and boosting type cylinder, though these 2 kinds of cylinders all each have advantage, if can and design a kind of novel cylinder then have more market prospects their advantages.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of boosting type multiposition cylinder is provided, and this cylinder has been integrated the advantage of multiposition cylinder and pressurized cylinder, exerts oneself big and complicated mechanical work to be implemented in can finish in the little working space.
For achieving the above object, the utility model adopts a kind of boosting type multiposition cylinder, comprise vat chamber, little cylinder chamber, small piston, big piston, middle piston, preceding bar and vent rod, vat chamber one end is provided with bonnet, the other end links to each other with little cylinder chamber by middle cover, and the other end of little cylinder chamber is provided with protecgulum; It is indoor that middle piston is positioned at little cylinder, and it is indoor that big piston and small piston all are arranged on vat, and big piston is shaped as the U type, and the central authorities of big piston offer inlet hole, are provided with the air inlet gap between big piston and the bonnet, and small piston places the bottom of big piston; Before the indoor middle piston of bar one end and little cylinder fixedly connected, the other end passes protecgulum and forms actuating station; Offer the gas-entered passageway of perforation in the vent rod along its axial direction, vent rod one end stretch in the little cylinder chamber and and middle piston between form air-inlet cavity, the indoor small piston of the vent rod the other end and vat is fixedlyed connected; On protecgulum, offer first inlet hole that is communicated with little cylinder chamber interior, on middle cover, offer the 4th inlet hole that is communicated with the vat chamber interior, on bonnet, offer second inlet hole and the 3rd inlet hole respectively, second inlet hole is communicated with gas-entered passageway in the vent rod by the inlet hole on the big piston, and the 3rd inlet hole is communicated with the air inlet gap.
The inwall that this practicality further is set to opening one side of big piston is provided with the anticreep collar.
This practicality further is set to form depression towards big piston one side on the bonnet and constitutes above-mentioned air inlet gap.
This practicality further is set to be provided with Sealing on the outer wall of small piston and between the inwall of big piston.
The utility model is by integrating the structure of pressurized cylinder and multiposition cylinder from cylinder interior, on vent rod, offer vent, dwindled whole external structure, realized in littler space, using, can realize the complicated mechanical action in conjunction with the difference of exerting oneself of vat chamber and little cylinder chamber.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Embodiment
As shown in Figure 1, specific embodiment of the utility model is a kind of boosting type multiposition cylinder, comprise vat chamber 1, little cylinder chamber 2, small piston 3, big piston 4, middle piston 5, preceding bar 6 and vent rod 7, vat chamber 2 one ends are provided with bonnet 8, the other end links to each other with little cylinder chamber 3 by middle cover 9, and the other end of little cylinder chamber 3 is provided with protecgulum 10; Middle piston 5 is positioned at little cylinder chamber 2, and big piston 4 and small piston 3 all are arranged in the vat chamber 1, and big piston 4 is shaped as the U type, and the central authorities of big piston 4 offer inlet hole, are provided with air inlet gap 81 between big piston 4 and the bonnet 8, and small piston 3 places the bottom of big piston 4; Preceding bar 6 one ends are fixedlyed connected with the middle piston 4 in the little cylinder chamber 2, and the other end passes protecgulum 10 and forms actuating station; Offer the gas-entered passageway 71 of perforation in the vent rod 7 along its axial direction, vent rod 7 one ends stretch in the little cylinder chamber 2 and and middle piston 5 between form air-inlet cavity, vent rod 7 the other ends and vat chamber 1 interior small piston 3 is fixedlyed connected; On protecgulum 10, offer first inlet hole 101 with little cylinder chamber 2 internal communication, on middle cover 9, offer the 4th inlet hole 91 with vat chamber 1 internal communication, on bonnet 8, offer second inlet hole 82 and the 3rd inlet hole 83 respectively, second inlet hole 82 is communicated with by the inlet hole on the big piston 4 and vent rod 7 interior gas-entered passageways 71, and the 3rd inlet hole 83 is communicated with air inlet gap 81.The inwall of opening one side of big piston 4 is provided with anticreep collar 11.Form depression towards big piston 4 one sides on the bonnet 8 and constitute above-mentioned air inlet gap 81.Be provided with Sealing on the outer wall of small piston 3 and between the inwall of big piston 4.
This cylinder combines vat chamber 1 and little cylinder chamber 2.When 82 air inlets of second inlet hole, when cylinder runs to the supercharging position, 83 air inlets of the 3rd inlet hole, the supercharge cylinders motion, the 3rd inlet hole 83 was stopped the supple of gas or steam after work put in place, 82 air inlets of second inlet hole, when cylinder was got back to the supercharging position, the air inlet area of first inlet hole 101 was bigger than the 4th inlet hole 91, so big piston 4 stops, the second last inlet hole 82 is stopped the supple of gas or steam, and cylinder is got back to original position.
