Detailed Description
The invention relates to a coiling machine capable of quickly changing a coiling block, which is described in detail with reference to the attached drawings and the detailed description.
As shown in fig. 1 and 2, a coiling machine capable of rapidly changing a coiling block comprises a coiling block main shaft 3, wherein an expansion and contraction component is arranged on the periphery of the coiling block main shaft 3, the coiling block main shaft 3 is of a hollow structure, a pull rod 1 is axially arranged in the coiling block main shaft 3, one end of the pull rod 1 is connected with a crosshead 5 corresponding to the expansion and contraction component, and the other end of the pull rod 1 is connected with a hydraulic oil cylinder 19 through a detachable connecting piece 7; under the condition that the hydraulic oil cylinder 19 drives the pull rod 1 to move, the crosshead 5 is used for driving the expansion and contraction component to move;
one end of the winding drum main shaft 3 is provided with a supporting component, the other end of the winding drum main shaft 3 is connected with the gear main shaft 4 through a flange component, the flange component is provided with a plurality of screw holes and gear main shaft screw holes 16 corresponding to the winding drum main shaft 3 and the gear main shaft 4 respectively, and the screw holes are connected with the gear main shaft screw holes 16 through handle bolts 6.
As shown in fig. 3, further, the screw holes include a first bobbin screw hole 17 axially corresponding to the gear spindle screw hole 16, and a second bobbin screw hole 18 connecting the first bobbin screw hole 17 through a conduction opening having a radial dimension larger than that of the first bobbin screw hole 17, wherein the opening dimension of the conduction opening is larger than the diameter of the fastening bolt 6.
Furthermore, the collapsible assembly comprises four axial wedges 9 and four radial wedges 12 corresponding to each axial wedge 9, four long grooves are uniformly formed in the circumferential direction of the winding drum main shaft 3 corresponding to the axial wedges 9, the axial wedges 9 are arranged in the long grooves, and the crosshead 5 is correspondingly connected with each axial wedge 9.
Further, the pull rod 1 is circumferentially sleeved with a disc spring 8 at a position close to the detachable connecting piece 7.
Further, the supporting component comprises a connecting sleeve 14 and an outer support 11, the connecting sleeve 14 is sleeved at one end of the reel spindle 3, and the outer support 11 is connected to the outer support 11 along the radial direction of the reel spindle 3.
Further, a spacer sleeve 10 is arranged between the connecting sleeve 14 and the reel spindle 3.
The working principle and the process of the coiling machine capable of quickly replacing the coiling drum are as follows;
the winding drum main shaft 3 is connected with the gear main shaft 4 through a bolt 6, the outer support 11 is contacted with a winding drum head of the winding drum main shaft 3 through a roller, due to the roller structure, when the winding drum main shaft 3 moves axially, the winding drum main shaft is always in close contact with a winding drum shaft of the winding drum main shaft 3, a spacer sleeve 10 is arranged between two bearings in the winding drum head of the winding drum main shaft 3, so that when the support sleeve contacted with a bearing inner ring rotates, a bearing outer ring and a winding drum head outer sleeve are relatively static with the outer support 11, so that when the winding drum works, an oil cylinder in the winding drum drives 5 through the cross head 1, the cross head 5 pushes the axial wedge 9 to move axially, and meanwhile, the radial wedge 12 expands and contracts radially, otherwise, the diameter is the working principle of the winding.
According to the coiling machine capable of quickly changing the coiling block, the coiling block main shaft 3 and the gear main shaft 4 are detachably arranged, and the coiling block main shaft 3 is optimized and improved, so that the purpose of quickly changing the coiling block is achieved, the operation efficiency of the coiling machine is improved to a certain extent, and the coiling machine has certain practical significance.
