Description
Technical field
The utility model relates to a kind of adjusting screw rod, specifically
oneplant New Buffering screw rod regulating mechanism, be applicable to the place of various adjusting screw rod series.
Background technique
Traditional buffering adjusting screw rod, adopt motor reducer to drive, its structure is that transmission shaft directly connects with motor reducer, and transmission shaft directly connects with driving screw, and transmission shaft is male splined shaft, and driving screw is internal spline, outer T-shaped motion thread.This traditional controlling mechanism has following two kinds of drawbacks: have some setbacks if driving screw rotates, and when having the phenomenons such as card pauses, motor reducer there will be the situations such as overload or even damage.It two is that traditional adjusting screw rod driving screw outside thread adopts T-shaped screw thread, and endoporus adopts splined hole, and processing relative difficulty, reduces conforming product rate.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of New Buffering screw rod regulating mechanism.
The utility model is by the following technical programs: a kind of New Buffering screw rod regulating mechanism, comprises support body, motor reducer, transmission shaft, driving screw and be arranged on mother nut on driving screw;
Described motor reducer is connected by torque force limiting device with transmission shaft;
Described transmission shaft is connected with joining shaft, and joining shaft is fixedly connected on the end of driving screw.
It is further: described driving screw axle center has unthreaded hole, and upper-end surface has deep gouge; Described joining shaft, driving screw are enclosed within transmission shaft successively, and joining shaft is fixedly connected on driving screw end by linking bond and bolt.
The described end winding support limited location block being positioned at the transmission shaft in driving screw axle center.
Described torque force limiting device is fixed on support body by buffering mounting bracket.
Described transmission shaft is provided with circumferential formula step, and the position on the downside of step is provided with thrust bearing, and the position on the upside of step is provided with tapered roller bearing; Described thrust bearing and tapered roller bearing are fixed on buffering mounting bracket by bearing support.
The utility model increases torque force limiting device between motor reducer and transmission shaft, protects motor reducer, transmission shaft, driving screw, the critical components such as nut, extends product working life, improves work efficiency; Increase a joining shaft in the middle of transmission shaft connects with driving screw, play the effect of a transition, the processing technology of complexity is transferred on joining shaft, reduce the difficulty of processing of driving screw, save cost, improve conforming product rate; Transmission shaft designs a step, the thrust bearing of an axially mounting is installed, prevents transmission shaft from down coming off; Transmission shaft bottom increases the limiting stopper of an axis, prevents from threading off.

In figure: 1, motor reducer; 2, mounting bracket is cushioned; 3, bearing support; 4, joining shaft; 5, linking bond; 6, transmission shaft; 7, driving screw; 8, mother nut; 9, torque force limiting device; 10, tapered roller bearing; 11, thrust bearing; 12, limiting stopper; 13, support body.
Embodiment
Be below a specific embodiment of the present utility model, existing the utility model is described in further detail by reference to the accompanying drawings.
As depicted in figs. 1 and 2, a kind of New Buffering screw rod regulating mechanism, motor reducer 1 is by torque force limiting device 9 connection for transmission axle 6, and transmission shaft 6 enters in the unthreaded hole in driving screw 7 axle center through bearing support 3, joining shaft 4 downwards successively.Again shown in composition graphs 3 and Fig. 4, joining shaft 4 has internal spline, and its lower end has deep gouge, has four equally distributed tapped holes at its periphery; Driving screw 7 axle center has unthreaded hole, and its upper-end surface has deep gouge; Joining shaft 4 is fixedly connected on driving screw 7 upper end by linking bond 5 and bolt.Again shown in composition graphs 5 and Fig. 7, the external splines coordinated with joining shaft 4 is had outside driving screw 7, be positioned at the end winding support limited location block 12 of the transmission shaft 6 in driving screw 7 axle center, the effect of limiting stopper 12 is when avoiding the situations such as workman's misoperation, phenomenon of threading off between transmission shaft and driving screw; Transmission shaft 6 is provided with circumferential formula step, position on the downside of step is provided with thrust bearing 11, position on the upside of step is provided with tapered roller bearing 10, thrust bearing 11 and tapered roller bearing 10 are fixed on buffering mounting bracket 2 by bearing support 3, and buffering mounting bracket 2 is fixed on support body 13.When practical set, all parts are all with between buffering mounting bracket 2 or be indirectly connected, and whole mechanism installation can form one independently after parts outside, and integral installation, in slide block both sides, improves mounting process, improves manufacturing efficiency.
Motor reducer drives drive axis, and transmission shaft drives driving screw to rotate by joining shaft, linking bond, and driving screw center is unthreaded hole, and mother nut maintains static, and cheaply can be realized rising and the decline function of driving screw by the clockwise and anticlockwise changing decelerating through motor.Add rotating coder, the electric control systems such as PLC just can realize numerical control function, numeral can set the distance risen and decline.The problems such as the utility model avoids overload, processed complex, do not worry problems such as threading off between transmission shaft and driving screw simultaneously yet.Extend product working life, improve work efficiency, reduce production and processing cost.
