At first, as shown in Figure 2, angle adjustable blowning installation for a kind of turning centre machine main shaft pine folder cutter provided by the utility model, mainly form by a cylinder body 20, a supercharging part 30, a piston 40, a locating ring 50, a positioning block 60, a fixture 70 and an elastic parts 80 assembly, wherein:

Cylinder body 20 has one and presses chamber 21 in it, and presses chamber 21 to be equipped with first and second source of the

gas

22,23, and the end at cylinder body 20 is formed with a groove 24 in addition, offers a passage 25 that communicates with pressure chamber 21 in groove 24 bottom surfaces, and offers an oil circuit 26 on the wall of passage 25.

Supercharging part 30 is formed with a depression bar 31 on it, but supercharging part 30 reciprocating actions ground group be located in the pressure chamber 21 of cylinder body 20, and depression bar 31 is subjected to passage 25 guidings and protrudes into groove 24.

Piston 40, the one end is formed with a side direction air flue 41, and the other end forms a holding part 42, holding part 42 is organized the groove 24 that is located at cylinder body 20 movably, the room 43 that in holding part 42, has corresponding depression bar 31, and outside holding part 42, be formed with a frizzen 44, be provided with first and second

inductive switch

45,46 at beginning, the end of the stroke of frizzen 44.

Locating ring 50 is formed with a location breach 51 on it, locating ring 50 is sheathed on piston 40, and the frizzen 44 of piston 40 is subjected to 51 of locating notches spacing.Locating piece 60 is sheathed on piston 40, and is positioned at the end face of locating ring 50, offers a lateral guide air flue 61 on it, and is connected with the 3rd source of the gas 62.Fixture 70 is sheathed on piston 40, and joins with the end face of locating piece 60.

Special feature of the present utility model is to be formed with on the locating piece 60 a ring protuberance 63, and a port of the airtube 61 of locating piece 60 is positioned at the end face of ring protuberance 63.Be formed with the storage tank 71 of a ring-type on the fixture 70, and on its cell wall, offer most elongated slots 72, storage tank 71 is sleeved on the ring protuberance 63 of locating piece 60, and forms a ring air chamber 73, communicates with the airtube 61 of locating piece 60 for the air flue 41 after piston 40 actions.In addition, be arranged with an elastic parts 80 between piston 40 and locating ring 50, and the one end is resisted against the holding part 42 of piston 40, the other end is resisted against locating piece 60.At last, as Fig. 4, shown in Figure 5, be provided with eight gag lever posts 74 between fixture 70 and cylinder body 20, and put along the axial rings winding of piston 40, the frizzen 44 of piston 40 then is limited between every adjacent gag lever post 74.

Further introduce manner of execution of the present utility model and effect below, as Fig. 2, shown in Figure 3, behind the storage tank 71 of fixture 70 and the ring protuberance 63 mutual fits of locating piece 60, be formed with a ring air chamber 73 with the periphery of piston 40, and ring air chamber 73 communicates with the airtube 61 of locating piece 60, and after piston 40 carries out axial action, when 41 mouthfuls of air flues treating piston 40 communicated with ring air chamber 73, the gases (this gas is continued to provide by the 3rd source of the gas 62) in the ring air chamber 73 were then by air flue 41 ejections of piston 40.Therefore when assembling, because the air flue 41 of piston 40 is for communicating with the airtube 61 of locating piece 60 by ring air chamber 73, therefore, the utility model is when assembling, the contraposition step of 41 mouthfuls of the air flues that can reduce

piston

40 and 61 mouthfuls of the airtubes of locating piece 60, make assembling more simple and easy, also just because of this, piston 40 can be done the adjustment of vertical axial on cylinder body 20, make the frizzen 44 on the piston 40 rotate adjustment thereupon, and be limited between every adjacent gag lever post 74 frizzen 44 corresponding with it first of piston 40 by this simultaneously, two

inductive switches

45,46 can be according to required and the change group is established angle, as Fig. 4, shown in Figure 5.

It should be noted that, as Fig. 2, shown in Figure 3, first inductive switch 45 is compressed by the frizzen 44 of piston 40 and controls first source of the gas 22 gases at high pressure are provided, 30 of supercharging parts are action vertically, and drives piston 40 and carry out axial action synchronously, and 80 of elastic parts are subjected to piston 40 actions and compress, when 41 mouthfuls of air flues treating piston 40 communicate with ring air chamber 73, gas in the ring air chamber 73 then sprays through the air flue 41 of piston 40, and the gases in each elongated slot 72 are detached, and makes each elongated slot 72 be vacuum state; Piston 40 in axial action, its frizzen 44 is pressed against second inductive switch 46, then control second source of the gas 23 gases at high pressure are provided, and allow first source of the gas, 22 stop supplies gases simultaneously, 40 in piston was subjected to the restoring force of elastic parts 80 immediately and returned to initial position this moment, and make the air flue 41 of piston 40 break away from ring air chamber 73, and because each elongated slot 72 interior no gas, therefore, the gas that the 3rd source of the gas 62 continues supply then is filled in earlier in each elongated slot 72, makes piston 40 can proceed axial action.

In sum, the utility model by the ring air chamber make piston can on cylinder body, do heavy d-axis to adjustment, make piston frizzen inductive switch corresponding with it can according to required change to organize establish angle, and can improve its packaging efficiency.
