Shown in Fig. 1, Fig. 2, Fig. 3 A, Fig. 3 B, Fig. 3 C, a kind of discharging processing machine electrode of the utility model rotating shaft group, its first embodiment mainly comprises:
One motor 10 is fixed in outside one first interconnecting device 16.
One transmission group 15 is organized in first interconnecting device 16, is made of first gear 17 and second gear 18 institute that is meshed, and this first gear 17 closes with power transmission shaft 11 pivots of motor 10.
One rotating shaft 20, its top and second gear, 18 pivots close, so can be by motor 10 driven rotary; The axle body of this rotating shaft 20 passes in one second interconnecting device 21 and the rotating shaft shell 22 in regular turn, this second interconnecting device 21 is mounted on first interconnecting device, 16 bottoms, this rotating shaft shell is located at second interconnecting device, 21 bottoms for 22 groups, establishes two bearings 23 in this rotating shaft shell 22 and wears pivot, peripheral hardware one conducting strip 221 for rotating shaft 20.
One chuck group 30 is made of in conjunction with a chuck 32 pull bar 31, but the cutter of this chuck 32 clippings discharge processing usefulness; This pull bar 31 closes the pull bar duct 24 that the footpath pivot is through at these rotating shaft 20 bottoms, the wall ring in this pull bar duct 24 is established several hole of beads 241, fill out a steel ball 25 in this hole of bead 241, ring is established a pearl groove 33 on this pull bar 31, can embed by the part that the hole of bead 241 protrudes from pull bar duct 24 for this steel ball 25.
One air clutch control structure comprises an end cap 41, is mounted on the axle body of these rotating shaft 20 nearly bottoms, and this end cap 41 times group is established a lower cover 42, one clutching members 43 and closed and directly be arranged between lower cover 42 and the rotating shaft 20; The wall ring of these clutching member 43 relative these rotating shafts 20 is established a bead returning groove 431; Establish a spring 44 between these clutching member 43 bottoms and the lower cover 42, with the strength that provides a normality up to shore, clutching member 43 inwalls are gone into steel ball 25 pushing tows in the hole of bead 241 and partly beading protrusion pull bar duct 24 are arranged; The avris that one air flue 45 axially runs through rotating shaft 20 is communicated in the inner space of this lower cover 42, establish an air drain 46 at the position of rotating shaft 20 relative these second interconnecting devices 21 ring in addition, this air drain 46 also is communicated with this air flue 45, this air drain 46 also is communicated with a pneumatic circuit 47 that is fixed on second interconnecting device 21, this pneumatic circuit 47 provides pressure air to inject this air drain 46, enter the inner space of this lower cover 41 via air flue 45, and act on the top of this clutching member 43, provide one to break through these spring 44 flexible strength that press down, make 431 pairs of the bead returning grooves should steel ball 25 (as Fig. 3 B), when pull bar 31 was down detached, this steel ball 25 was retracted in this bead returning groove 431 by pearl groove 33 pushing tows of pull bar.Otherwise, to let out except that gas pressure, this spring 44 pushes back this clutching member 43, and steel ball 25 pushing tows are protruded the hole of bead 241.Press by the notes of gas in view of the above and release, control this clutching member 43 and axially move back and forth, make steel ball 25 must protrude pull bar duct 24, perhaps withdraw from pull bar duct 24 with removal pull bar 31 and chuck 32 in conjunction with pull bar 31 and chuck 32.For reaching airtight effect, between this rotating shaft 20 and second interconnecting device, 21 inwalls, between this end cap 41 and the lower cover 42, between clutching member 43 and lower cover 42 inwalls and between clutching member 43 and rotating shaft 20 outer walls, respectively establish at least one leak-proof gasket 48, avoid gas to leak, guarantee that air pressure can act on this clutching member 43 fully, controls the stroke that moves down of this clutching member exactly.
One working fluid injecting structure comprises one and connects the fluid passage 51 that these rotating shaft 20 axle center are communicated to this pull bar duct 24, and this fluid passage 51 is connected with the fluid pipeline 52 that is fixed to first interconnecting device 16, in order to do injecting processing fluid; These pull bar duct 24 first halves are established a leakproof jacking block 53, and these leakproof jacking block 53 central authorities also establish wholeheartedly that hole 531 fuel feeding liquid are circulated to pull bar 31 and chuck 32; Establish a spring 54 between this leakproof jacking block 53 and 24 tops, pull bar duct,, make leakproof jacking block 53 and pull bar 31 top fluid-tight engagement, fluid can be poured in pull bar and the chuck really, prevent that fluid from leaking outside by oiling pressure and spring 54 pushing tows.As Fig. 3 C, when removal pull bar 31 and chuck 32, discharge air pressure, clutching member 43 is moved in spring 44 ejections reset, steel ball 25 ejection convexes in pull bar duct 24, can be blocked this leakproof jacking block 53, avoid its down slippage.
Shown in Fig. 4, Fig. 5, Fig. 6 A, Fig. 6 B, Fig. 6 C, it is partly identical with first embodiment that the utility model second embodiment also comprises motor 10, rotating shaft 20, chuck group 30 and working fluid injecting structure etc., do not add the gift presented to a senior at one's first visit as a mark of esteem at this and state.Only second embodiment rechanges with the major technique of air clutch control structure and designs the manual clutch control structure.
This manual clutch control structure comprises an end cap 61, is mounted on the axle body of these rotating shaft 20 nearly bottoms, and this end cap closes the footpath for 61 times and sets a lower cover 62, and keep out in the base of this lower cover 62 with a clasp 63 these rotating shaft 20 bottoms, prevents that lower cover 62 breaks away from; The wall ring of these lower cover 62 relative these rotating shafts 20 is established a bead returning groove 621; Establish a spring 64 between this lower cover 62 and the end cap 61, the strength that lower cover is pushed away for 62 times is provided normally, the lower cover inwall in pull bar duct 24, in the pearl groove 33 that embeds pull bar 31, reaches the purpose of steady brace 31 with steel ball 25 pushing tow convexes.Otherwise, outside and up push away and pull out to hold this lower cover 62, break through the elastic force of this spring 64, make 621 pairs of the bead returning grooves should steel ball 25, when pull bar 31 was down detached, this steel ball 25 was retracted in this bead returning groove 621 by pearl groove 33 pushing tows of pull bar.
The utility model is controlled the part beading protrusion of this steel ball 25 or is recessed pull bar duct 24 with pneumatic control structure or manual control structure, to reach purpose in conjunction with pull bar or release pull bar, making group change pull bar and chuck stirs work and can finish easily to push away, easily and fast and accurate positioning, particularly pneumatic control mode makes the utility model more can cooperate Chu Daocang to carry out the automatic tool changer action.
Though this case is to do explanation with two most preferred embodiments, is skillful in this skill person and can makes various multi-form changes not breaking away under this case spirit and the category.Above illustrated embodiment is only in order to explanation this case, and is non-in order to limit the scope of this case.Such as do not disobey various modifications or the variation that this case spirit is engaged in, all belong to this case claim.
