The invention discloses a coil winding support for an electric generator, which comprises a stander, a plurality of wire spool devices, a pneumatic brake valve and a damp ejector rob, wherein the stander comprises a base plate and a plurality of vertical rods, wherein the lower ends of the vertical rods are fixed on the base plate, and the heights of the vertical rods are gradually reduced, the wire spool devices are arranged at the upper ends of the vertical rods, each wire spool device comprises a support shaft and a wire spool, one ends of the support shafts are supported in bearing boxes by bearings, the bearing boxes are fixed at the upper ends of the vertical rods, and the wire spools are fixedly connected with the support shafts; and the lower sides of the wire spool devices are joined with the pneumatic brake valve, and the damp ejector rob is arranged at the upper side of the pneumatic brake valve. The coil winding support is simple in structure, and convenient to operate. The damp ejector rob is additively arranged between the wire spools and the pneumatic brake valve, so that the problem that the wire spools positively rotate and negatively rotate along with the inertia when a wire coiling machine stops can be avoided. According to the coil winding support, the wire spools are axially braked by the pneumatic brake valve, so that the brake moment can be greatly reduced, the transverse load can not be applied to the support shafts, the fault that the support shafts are flatly pressed can be avoided, and the service life of the coil winding support can be prolonged.
Description
Technical field
The present invention relates to the special equipment that a kind of motor is made, especially a kind of when being used for the electricity generator stator coil coiling unwrapping wire drum stand, belong to the motor manufacturing equipment technical field.
Background technology
Electricity generator stator coil adopts the coil winding machine coiling, and during coil winding machine main shaft rotation coiling stator coil, the drum of drum stand needs to discharge synchronously copper wires, places a plurality of wire spools on the drum stand, and the confession coil winding machine is with many copper wires and become a circle coiling.The wire spool of existing drum stand adopts two rows centralized arrangement mode, two wire spools of every row, though floor space is little, higher because of center of gravity, the long-time running meeting produces vibrations because of anchor bolt is loosening, influences the coiling quality of coil.Four wire spools adopt the two rows horizontal arrangement, and the copper wires on two wire spools discharges on same horizontal level, are easy to generate that copper wires is staggered twines, and must manual work make in order could the coiling stator coil, influences operating efficiency.When coil winding machine quit work, wire spool must stop operating synchronously, can prevent that just copper wires is lax around not tightening subcoil.Existing drum stand adopts the dry type friction pulley of pneumatic control to press down the radial system flowing mode at the block plate edge of wire spool, because the linear velocity at the block plate edge of wire spool is maximum, required braking moment is also big, and the wearing and tearing of dry type friction pulley are very fast; Because braking moment is big, causes back shaft to be pressed partially, influences wire spool and discharge copper wires.
Summary of the invention
Can not take place when the purpose of this invention is to provide a kind of simple in structure, unwrapping wire that many copper wires are staggered twines, the wire spool braking moment is less, easy to use, the generator coil drum stand of high efficiency.
The present invention is achieved through following technical scheme:
A kind of generator coil drum stand; Comprise frame, several wire spool devices, aerobraking valve and damping push rod; Said frame comprises that base plate, several lower end are separately fixed at the vertical rod on the base plate, the height of several vertical rods reduces gradually, and the vertical rod upper end connects into ladder-shaped frame through brace; The wire spool device is arranged on the vertical rod upper end, comprises back shaft, wire spool,, back shaft one end is bearing in the bearing box through bearing, and bearing box is fixed on the vertical rod upper end, and back shaft axis and vertical rod facade intersect vertically, and wire spool is fixedly connected with back shaft; Wire spool device downside is connected with the aerobraking valve, and the damping push rod is arranged on aerobraking valve upside, and damping push rod one end is fixed in the vertical rod, and the damping push rod other end withstands on the wire spool.
The object of the invention can also further realize through following technical measures.
Aforesaid generator coil drum stand, wherein said aerobraking valve one end is fixed in the vertical rod, and the aerobraking valve other end is provided with compressed air inlet, and aerobraking valve upside is provided with groove, and the block plate downside of wire spool one end is arranged in groove.
Aforesaid generator coil drum stand, wherein said damping push rod comprises the housing of push rod, spring and containing push rod, spring, and said push rod one end is supported on spring one end, and the push rod other end is resisted against on the block plate end face.
The present invention is simple in structure, easy to operate; The base areas of frame is bigger, and the height of several vertical rods is fixed on the base plate with reducing gradually, and wire spool reduces high inclination one by one and is arranged on the frame; The center of gravity of complete machine is lower; Anchor bolt can not become flexible, and complete machine can not shake, and has improved the coiling quality of coil.The present invention has set up the damping push rod between the block plate of wire spool and pneumatic brake valve, sluggish power has been set up in the rotation of wire spool, and wire spool is along with the problem of inertia forward or reverse when avoiding appearing at coil winding machine and stopping.The block plate downside of wire spool one end of the present invention is arranged in the groove of aerobraking valve upside; The dry type friction pulley of prior art is pressed down the radial system flowing mode at the block plate edge of wire spool; The brake block that changes the aerobraking valve into clamps the mode that the block plate both ends of the surface of wire spool are axially braked wire spool, greatly reduces braking moment, and back shaft does not receive transverse load; Back shaft can not take place pressed the inclined to one side problem that influences unwrapping wire, prolonged the useful life of drum stand.A plurality of wire spool height become oblique arrangement to be arranged on corresponding vertical rod upper end gradually with reducing, and the height of each wire spool release copper wires is inconsistent, can not produce the staggered problem that influences coil winding of twining of copper wires.
Advantage of the present invention and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the enlarged left view of Fig. 1;
Fig. 3 is the I portion enlarged drawing of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Like Fig. 1-shown in Figure 3, present embodiment comprises frame 1,6 wire spool devices 2, aerobraking valve 3 and damping push rods 4, and frame 1 is a welding structural element, comprises 11,6 vertical rods 12 that reduce highly gradually of base plate, vertical rod 12 lower ends and base plate 11 weldering companies.Brace 13 is linked to be ladder-shaped frame with each vertical rod 1 upper end weldering.Wire spool device 2 is arranged on vertical rod 12 upper ends; Comprise back shaft 21, wire spool 22; Back shaft 21 1 ends are bearing in the bearing box 23 through bearing; Bearing box 23 1 ends are fixed on vertical rod 12 upper ends through securing member, and back shaft 21 axis and vertical rod facade intersect vertically, and wire spool 22 and back shaft 21 are fixedly connected through flat key.Wire spool device 2 downsides are connected with aerobraking valve 3.Present embodiment is provided with 6 wire spools 22 altogether, the coil of 6 copper wires of ability coiling and a circle.Be with a plurality of axle sleeves on the back shaft 21, back shaft 21 other ends are equipped with end cap 211, carry out spacing to the wire rod axle sleeve that is enclosed within on the back shaft 21.
