The utility model discloses an angling cylinder which comprises a piston rod, a cylinder barrel, a cylinder cover and a swivel joint body. The swivel joint body is arranged at one end of the piston rod in an embedding mode. The cylinder barrel is embedded at the other end of the piston rod. The cylinder cover and the cylinder barrel are fixedly connected through a fastening piece. The piston rod and the cylinder barrel form a front cavity. The piston rod and the cylinder cover form a back cavity. First double channels and second double channels are arranged in the piston rod. A first oil opening is formed in the outer end face of the swivel joint body. A second oil opening communicated with a first channel is formed in the piston rod. A third oil opening is formed in the outer end face of the swivel joint body. A fourth oil opening communicated with a second channel is formed in the piston rod. According to the angling cylinder, double-hole oil going in and double-hole oil going out can be achieved, hydraulic oil flow is increased, during part clamping, stability is good, and time for clamping and loosening is shortened.

Further, described passage one is connected with ante-chamber, and described passage two is connected with back cavity.

Further, in piston rod central position, be also provided with the central passage of ventilation.

Further, described Twin channel one arranges about piston rod Central Symmetry.

Further, described Twin channel two arranges about piston rod Central Symmetry.

The utility model is obtained following beneficial effect: Twin channel oil inlet and oil return is set, has accelerated the speed of response of clamping and loosening cutter, shortened processing auxiliary time; In piston rod central position, be also provided with central passage, for ventilation, can carry out aeration cleaning to knife bar taper shank portion, the assembly precision when guaranteeing to change the outfit cutter.

Accompanying drawing explanation

Fig. 1 is a kind of angling cylinder embodiment's of the utility model structural representation one;

Fig. 2 is a kind of angling cylinder embodiment's of the utility model structural representation two.

Embodiment

As shown in Figure 1-2, as embodiment of the present utility model, a kind of angling cylinder, comprise piston rod 4, cylinder tube 1, oil cylinder cover 2, swivel coupling body 3 and bearing (ball) cover 14, described swivel coupling body 3 is nested on piston rod 4 one end, bearing (ball) cover 14 is arranged on the exterior edge face of swivel coupling body 3 swivel coupling body 3 is more firmly arranged on piston rod 4, described cylinder tube 1 is nested on the other end of piston rod 4, described oil cylinder cover 2 is positioned at the inner side of cylinder tube 1 and is fixedly connected with described cylinder tube 1 by fastening piece, described piston rod 4 forms ante-chamber 5 with cylinder tube 1, described piston rod 4 forms back cavity 6 with oil cylinder cover 2, in described piston rod 4, be provided with Twin channel 1 and Twin channel 2 10, described Twin channel 1 is connected with ante-chamber 5, in swivel coupling body 3 exterior edge faces, be provided with for the logical oil of passage 1, the hydraulic fluid port 1 of oil return and be provided with the hydraulic fluid port 29 communicating with passage 1 on piston rod 4, described Twin channel 2 10 is connected with back cavity 6, is provided with for passage 2 10 leads to the hydraulic fluid port 3 11 of oil, oil return and on piston rod 4, be provided with the hydraulic fluid port 4 12 communicating with passage 2 10 in swivel coupling body 3 exterior edge faces.

Described Twin channel 1 is about piston rod 4 Central Symmetry settings; Described Twin channel 2 10 is being on 90 ° of crossing longitudinal sections and about piston rod 4 Central Symmetry settings with Twin channel 1.

In piston rod 4 central positions, be also provided with the central passage 13 of ventilation.

This angling cylinder working principle: from hydraulic fluid port one 8 oil-feeds as shown in Figure 1, the flow through revolution oil groove of swivel coupling body 3 of oil, by hydraulic fluid port 29, flow in Twin channel 1, through Twin channel 1, flow in ante-chamber 5, piston rod 4 retreats, tension knife bar, as shown in Figure 2, oil is by Twin channel 2 10 oil returns that are connected with back cavity 6; From hydraulic fluid port 3 11 oil-feeds as shown in Figure 2, the flow through revolution oil groove of swivel coupling body 3 of oil, flow in Twin channel 2 10 by hydraulic fluid port 4 12, through Twin channel 2 10, flow in back cavity 6, piston rod 4 advances, and unclamps knife bar, as shown in Figure 1, oil is by Twin channel one 7 oil returns that are connected with ante-chamber 5.Angling cylinder of the present utility model by Twin channel oil inlet and oil return, has been accelerated the speed of response of clamping and loosening cutter, has shortened processing auxiliary time.
