Abstract
The utility model belongs to the technical field of transmission components for connecting transmission gears with dies, and discloses a joint, which is mainly technically characterized by comprising a square head and a center shaft. The square head can be inserted into a groove at the end of a die, a square head sleeve hole and an annular sleeve are arranged on one side close to the rear of the square head, a shaft sleeve is sleeved on the center shaft on the rear of the square head, a shaft sleeve head which is inserted into the annular sleeve is disposed at the front end of the shaft sleeve, the outer diameter of the shaft sleeve head is smaller than the inner diameter of the annular sleeve, a key capable of leading the square head and the shaft sleeve to axially move along the center shaft is arranged on a rotating shaft, a first sprocket and a second sprocket are respectively disposed on the outer side of the annular sleeve and the outer side of the shaft sleeve close to the side with the shaft sleeve head, and a double-row chain is sleeved on the first sprocket and the second sprocket. During rotation, the axis line of the die jumps within a certain range while an output shaft of a transmission gear does not jump together, and the joint prevents breakage of a transmission shaft due to fatigue, incapability of fixing of the transmission gear and damage of other components.
Description
Technical field
The utility model belongs to the technical field of transmission that connects gearbox and mould, relates to a kind of bond head concretely.
Background technique
Joint head is the transmission part that connects gearbox and mould, when needing mould to rotate joint head is moved forward, and its side falcon is embedded in the groove of mould one end, and the power (torque) of jack shaft output is passed to mould.To move behind the joint head when needing mould to stop operating, its side falcon is deviate from from the groove of mould, cut off power source.
Die length is bigger, generally reaches 6-12 meters, and the strong point is at two ends during work, because resiliently deformable, there is certain amount of deflection in its shaft axis, and because the flexible nonuniformity of mold integral, the shaft axis of mould is beated within the specific limits in the rotation process.Therefore output shaft of gear-box shaft axis and mould shaft axis can only guarantee coaxial in to a certain degree.
The joint head of usefulness had two kinds in the past: one, but be aligning, employing be the principle of sliding cross coupling, the manufacturing expense height.Because the reason of working environment and the structure narrow limitation of itself are adjusted underaction automatically, not only the high maintenance of rate of fault is frequent, and can not in time find and will cause the accident after damaging in the work.It two is not alignings of integrative-structure, though make simply, often the decentraction because of mould and transmission shaft causes: mould is lifted, transmission shaft can't be fixed and other parts damages because of fatigue fracture, gearbox.
The model utility content
The technical problem that the utility model solves just provides a kind of simple in structure, long service life, can effectively reduce the bond head that gearbox and transmission shaft are damaged.
For solving the problems of the technologies described above, the technological scheme that the utility model proposes is: comprise the square toes and the axis that can insert in the mould ends groove, described square toes are provided with square toes trepanning and ring-shaped sleeve near rear one side, on the axis at described square toes rear, be with axle sleeve, be provided with the axle sleeve head that inserts in the described ring-shaped sleeve at this axle sleeve front end, the external diameter of described axle sleeve head is less than the internal diameter of described ring-shaped sleeve, described rotating shaft is provided with and makes square toes and axle sleeve along the axially movable key of axis, outside the described ring-shaped sleeve outside and axle sleeve, be respectively arranged with first sprocket wheel and second sprocket wheel, on described first sprocket wheel and second sprocket wheel, be with double strand chain near the first side of described axle sleeve.
Its additional technical feature is: described axle sleeve is provided with shift fork.
The bond head that the utility model provides, compare with prior art and to have the following advantages: one, owing to comprise the square toes and the axis that can insert in the mould ends groove, described square toes are provided with square toes trepanning and ring-shaped sleeve near rear one side, on the axis at described square toes rear, be with axle sleeve, be provided with the axle sleeve head that inserts in the described ring-shaped sleeve at this axle sleeve front end, the external diameter of described axle sleeve head is less than the internal diameter of described ring-shaped sleeve, described rotating shaft is provided with and makes square toes and axle sleeve along the axially movable key of axis, outside the described ring-shaped sleeve outside and axle sleeve, be respectively arranged with first sprocket wheel and second sprocket wheel near the first side of described axle sleeve, on described first sprocket wheel and second sprocket wheel, be with double strand chain, when the needs mould rotates, square toes are inserted in the groove of mould ends, give mould the transmission of power of jack shaft output; Move behind the joint head when needing mould to stop operating, its square toes are deviate from from the groove of mould, cut off power source.Mould is long because of length, resiliently deformable takes place in rotation process, there is certain amount of deflection in its shaft axis, and because the flexible nonuniformity of mold integral, the shaft axis of mould is beated within the specific limits in the rotation process, and the external diameter of axle sleeve head is less than the internal diameter of described ring-shaped sleeve, mould and square toes are beated together, but axis and axle sleeve are not beated with square toes, like this, can not cause transmission shaft can't fix and other parts damages because of fatigue fracture, gearbox; Its two because described axle sleeve is provided with shift fork, make that square toes and axle sleeve advance and retreat are convenient.
Description of drawings

Fig. 2 is the left view of Fig. 1;
Structural representation when Fig. 3 uses for bond head.
Embodiment
Be described further below in conjunction with the structure of accompanying drawing the bond head that the utility model proposed.
As Fig. 1, Fig. 2 and shown in Figure 3, be the structural representation of bond head.Its structure includes the square toes 4 and the axis 2 that can insert in mould 3 end recesses 31, square toes 4 are provided with square toes trepanning 41 and ring-shaped sleeve 42 near rear one side, on the axis 2 at square toes 4 rears, be with axle sleeve 5, front end at this axle sleeve 5 is provided with the axle sleeve head 51 that inserts in the ring-shaped sleeve 42, the external diameter of axle sleeve head 51 is less than the internal diameter of ring-shaped sleeve 42, axis 2 is provided with and makes square toes 4 and axle sleeve 5 along the axially movable key 21 of axis, in ring-shaped sleeve 42 arranged outside first sprocket wheel 43 is arranged, in arranged outside second sprocket wheel 52 is arranged near the axle sleeve 5 of axle sleeve head 51 1 sides, on first sprocket wheel 43 and second sprocket wheel 52, be with double strand chain 53, when the needs mould rotates, square toes 4 are inserted in the groove 31 of mould 3 ends, give mould 3 transmission of power of gearbox 1 transmission shaft output; Move behind the joint head when needing mould 3 to stop operating, its square toes 4 are deviate from from the groove 31 of mould 3, cut off power source.Mould 3 is long because of length, only support by supporting runner 7 at the two ends of mould, therefore resiliently deformable takes place in rotation process, there is certain amount of deflection in its shaft axis, and because the nonuniformity of mould 3 integral, flexibles, the shaft axis of mould is beated within the specific limits in the rotation process, the external diameter of axle sleeve head 51 is less than the internal diameter of ring-shaped sleeve 42, mould 3 and square toes 4 are beated together, but axis 2 and axle sleeve 5 are not beated with square toes 4, like this, can not cause transmission shaft can't fix and other parts damages because of fatigue fracture, gearbox 1.
In order to make square toes and axle sleeve advance and retreat convenient, axle sleeve 5 is provided with shift fork 54.
