Description
Technical field
The utility model relates to the product cylinder manufacturing technology, especially refers to a kind of product cylinder structure of tool dual piston bar.
Background technique
Cylinder is a kind of pneumatic element very commonly used, and it utilizes pressurized air to promote piston, makes piston rod produce motion and drive mechanical part to move.In actual application, so that finish the processing technology of one procedure, just often need the continuous action of a plurality of cylinders to finish; Because every in these a plurality of cylinders can only finish single action, inefficiency not only, and be easy to inharmonious generation the " collisions " image owing to cylinder operation, the installation of a plurality of cylinders can cause fixture component to assemble inconvenient, workpiece processing precise decreasing.For this reason, people expect that the product cylinder of inventing a plurality of actions of a kind of tool comes out, and to overcome the defective and the deficiency of existing common cylinder component function singleness, satisfy the application of multiple operation processing or multiple tracks control technology required.
The model utility content
The technical problems to be solved in the utility model is defective and the deficiency that overcomes existing like product inefficiency, fixture component assembling inconvenience and workpiece processing precise decreasing, provide the product cylinder of a plurality of actions of a kind of tool to society, satisfy the application of multiple operation processing or multiple tracks control technology required.
The technological scheme that its technical problem that solves the utility model adopts is: the combined type double-acting cylinder comprises the assembly cylinder-body that is linked to each other and constituted by long cylinder body and short cylinder body, be provided with the long-term job stopper rod in the described long cylinder body, be provided with short piston rod in the described short cylinder body, described long cylinder body two ends are respectively equipped with front end housing and back cylinder cover, and described short cylinder body two ends are respectively equipped with front cover and rear end cover; Described short piston rod is a sleeve shape, and the two ends of described long-term job stopper rod all stretch out in the front/rear end of described long cylinder body; The axial region that described long-term job stopper rod stretches out in described front end housing passes described short piston rod cavity, stretches out in the front cover of described short cylinder body; Described long-term job stopper rod and the coaxial setting of described short piston rod.
The end that described long-term job stopper rod stretches out in described back cylinder cover is provided with spacing adjusting nut.
The utility model combined type double-acting cylinder, described long-term job stopper rod pass described short piston rod cavity and setting coaxial with it, stretch out in the front cover of described short cylinder body; After the air inlet/outlet of described long cylinder body and described short cylinder body is connected operating air pressure, utilize air pressure to control stretching out of described long-term job stopper rod and described short piston rod respectively or bounce back, thereby realize the two continuous actions of moving of a cover, improved cylinder operation efficient greatly.Compare than existing product, this product has running clearance weak point, coordination, advantage that machining accuracy is high, can satisfy the application of multiple operation processing or multiple tracks control technology required.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model combined type double-acting cylinder comprises by long cylinder body 11 and the assembly cylinder-body that short cylinder body 1 links to each other and constitutes, and is provided with long-term job stopper rod 5 in the described long cylinder body 11, is provided with short piston rod 4 in the described short cylinder body 1, and described short piston rod 4 is a sleeve shape; Described long-term job stopper rod 5 is provided with long-term job plug 10, and described long cylinder body 11 two ends are respectively equipped with front end housing 9 and back cylinder cover 14, and sidepiece is established suction port 13 and air outlet 12; Described short piston rod 4 is provided with short piston 7; Described short cylinder body 1 two ends are respectively equipped with front cover 6 and rear end cover 8, and sidepiece is established suction port 3 and air outlet 2; The two ends of described long-term job stopper rod 5 all stretch out in the front/rear end of described long cylinder body 11, the end that wherein stretches out in described back cylinder cover 14 is provided with spacing adjusting nut 15, described long-term job stopper rod 5 axial regions that stretch out in described front end housing 9 pass described short piston rod 4 inner chambers, stretch out in the front cover 6 of described short cylinder body 1, described long-term job stopper rod 5 and described short piston rod 4 coaxial settings.
Continue in conjunction with the accompanying drawings the working principle of summary the utility model product below.As shown in Figure 1, the described long-term job stopper rod 5 of this product and the end of described short piston rod 4 all stretch out in the front cover 6 of described short cylinder body 1, can be connected different fixture components according to actual needs in the end of described long-term job stopper rod 5 and described short piston rod 4.After the suction port 3 of described short cylinder body 1 was connected operating air pressure, the right side pressurized of described short piston 7 stretched out described short piston rod 4 left and produces an action; And then connect operating air pressure at the suction port 13 of described long cylinder body 11, the right side pressurized of described long-term job plug 10 also stretches out described long-term job stopper rod 5 left and produces an action, thereby has realized the two moving continuous actions of a cover, has improved cylinder operation efficient greatly.Based on same principle, connect operating air pressure in air outlet 2 when described short cylinder body 1, the left side pressurized of described short piston 7 bounces back described short piston rod 4 to the right; And then connect operating air pressure in the air outlet 12 of described long cylinder body 11, the left side pressurized of described long-term job plug 10 also bounces back described long-term job stopper rod 5 to the right, and this modular cylinder resets.
