Background technology
The Effec-tive Function of lathe is closely related with the performance of actuating device, spindle gear includes screw mandrel and motor, and screw mandrel operation is by motor-driven, existing spindle gear uses shaft coupling transmission, mounting means seems simple and convenient, but motor needs and screw mandrel is direct-connected, and direct-connected needs take longer space, can affect the entire length of equipment, width, highly, the most existing spindle gear also needs to promote in terms of operation stability.
Summary of the invention
For the deficiencies in the prior art, this utility model provides screw mandrel and the motor high-efficiency transmission device of a kind of compact conformation, good stability and precise control.
The technical solution of the utility model is: a kind of screw mandrel and motor high-efficiency transmission device, seat is fixed including screw mandrel, screw mandrel, synchronous belt drive mechanism, motor fixing plate and servomotor, it is characterized in that: seat side fixed by described screw mandrel, and vertically-mounted to have motor fixing plate and screw mandrel to fix seat bottom face concordant with motor fixing plate bottom surface, screw mandrel is fixed seat opposite side and is provided with screw mandrel, motor fixing plate top is provided with servomotor, servomotor and screw mandrel are positioned at the same side of motor fixing plate, on described motor fixing plate, the opposite side of non-installation motor is provided with synchronous belt drive mechanism, described synchronous belt drive mechanism includes the synchronization wheel A set gradually from top to bottom, Timing Belt and synchronization wheel B, the described wheel A diameter that synchronizes is less than synchronization wheel B, the described wheel A that synchronizes is connected with the rotating shaft of servomotor, synchronization wheel B is fixing with screw mandrel one end to be connected.
The described tooth ratio synchronizing wheel A and synchronization wheel B is 30:40.
Described Timing Belt is the closed ring rubber strip that inner peripheral surface is provided with equidistant tooth.
Described Timing Belt is provided with the carrying rope of low elongation.
Described carrying rope is made up of the material such as glass fibre or steel wire.
Threaded with screw or slide block in described screw mandrel one end.
Described screw mandrel is fixed seat and is included fixing seat main body and a bracer, and described bracer is arranged at fixing seat bottom part body.
The beneficial effects of the utility model are:
1, using synchronization wheel rear motor and screw mandrel installation direction is in same direction, and equipment was compared installing space and can be saved the length of a motor relatively in the past, shortens overall drive mechanism length, more compact structure, and has stable and that control accuracy is high advantage.
2, the mode of little wheel belt bull wheel is used, synchronizing wheel A section is motor output end, and synchronizing wheel B end is screw mandrel input, and synchronization wheel A/ synchronizes the tooth ratio 30/40 of wheel B and improves, strengthening the moment of torsion of motor, the transmission between screw mandrel and screw is played certain cushioning effect by the flexibility of Timing Belt itself.

In figure, 1-screw mandrel fixes seat, 2-motor fixing plate, 3-servomotor, 4-screw mandrel, and 5-synchronizes wheel A, 6-Timing Belt, and 7-synchronizes wheel B.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further:
nullAs depicted in figs. 1 and 2，A kind of screw mandrel and motor high-efficiency transmission device，Seat 1 is fixed including screw mandrel、Screw mandrel 4、Timing Belt 6 drive mechanism、Motor fixing plate 2 and servomotor 3，It is characterized in that: seat 1 side fixed by described screw mandrel, and vertically-mounted to have motor fixing plate 2 and screw mandrel to fix seat 1 bottom surface concordant with motor fixing plate 2 bottom surface，Screw mandrel is fixed seat 1 opposite side and is provided with screw mandrel 4，Motor fixing plate 2 top is provided with servomotor 3，Servomotor 3 and screw mandrel 4 are positioned at the same side of motor fixing plate 2，On described motor fixing plate 2, the opposite side of non-installation motor is provided with Timing Belt 6 drive mechanism，Described Timing Belt 6 drive mechanism includes the synchronization wheel A5 set gradually from top to bottom、Timing Belt 6 and synchronization wheel B7，The described wheel A5 diameter that synchronizes is less than synchronization wheel B7，The described wheel A5 that synchronizes is connected with the rotating shaft of servomotor 3，Synchronization wheel B7 is fixing with screw mandrel 4 one end to be connected.
As further scheme of the present utility model, threaded with screw or slide block in described screw mandrel 4 one end, described screw mandrel is fixed seat 1 and is included fixing seat main body and a bracer, described bracer is arranged at fixing seat bottom part body, the described tooth ratio synchronizing wheel A5 and synchronization wheel B7 is increased to 30:40, described Timing Belt 6 is provided with the closed ring rubber strip of equidistant tooth for inner peripheral surface, described Timing Belt 6 is provided with carrying rope, described carrying rope uses the glass fibre that percentage elongation is the least, the materials such as steel wire are made, Timing Belt 6 transmission is a kind of engaged transmission, although Timing Belt 6 is elastomer, but owing to wherein bearing the carrying rope of load, there is the characteristic not extended, therefore belt pitch can be kept constant, make band and wheel teeth groove energy correct engagement, realize the Synchronous Transmission without slippage, obtain accurate gear ratio.
