The servo pressurization mechanism is characterized by being provided with a piston rod for pressurizing and a ball screw mechanism, wherein the piston rod is supported on a shell in a sliding manner and is fixedly connected with a guide sleeve; the guide sleeve is sleeved on a guide rod; the guide rod is positioned and supported relative to the shell; the axis of the guide rod is parallel to that of the piston rod; the ball screw mechanism consists of a ball screw and a ball nut; the ball nut is fixedly connected with the piston rod; the ball screw is matched with the ball nut; one end of the ball screw is connected with a second synchronous wheel; the second synchronous wheel is connected with a first synchronous wheel through a synchronization band in a transmission manner; and the first synchronous wheel is connected with a servo motor in a transmission manner. The servo pressurization mechanism has a simple structure and precise transmission property, can work stably, is low in cost, and is applicable to a servo welding gun.
Description
Technical field
The utility model relates to the electric welding equipment field, the servo pressing mechanism in particularly a kind of servo torch.
Background technology
In machine-building, use the industrial robot soldering turret that workpiece is welded in all trades and professions automatically and applied, this application is more general in auto manufacturing especially.The industrial robot soldering turret generally is made up of manipulator and electric resistance welder two parts.Wherein, the comparatively advanced at present technology of electric resistance welder is to adopt servo torch, and servo torch is made up of welding gun and servo pressing mechanism usually.The shortcoming that at present existing servo pressing mechanism exists is: 1. poor reliability; 2. complex structure; 3. cost is high.Therefore, how to design the problem that a kind of good reliability, servo pressing mechanism simple in structure and that cost is low are the utility model research.
Summary of the invention
The utility model provides the servo pressing mechanism in a kind of servo torch, is intended to solve the high problem of poor reliability, complex structure and cost that existing at present servo pressing mechanism exists.
For achieving the above object; The technical scheme that the utility model adopts is: the servo pressing mechanism in a kind of servo torch, and its innovation is: said servo pressing mechanism has the piston rod of pressurization together, and this piston rod sliding bearing is on a housing; Piston rod is fixedly connected with a fairlead; Fairlead is enclosed within on the guide post, guide post relative housing positioning support, the axis of guide post and the parallel axes of piston rod.
Said servo pressing mechanism also is provided with a ball wire rod mechanism; This ball wire rod mechanism is made up of ball screw and ball nut; Ball nut is fixedly connected with piston rod, and ball screw cooperates with ball nut, and an end of ball screw links to each other with one second synchronizing wheel; Second synchronizing wheel is with one first synchronizing wheel through synchronously and is in transmission connection, and first synchronizing wheel and a servomotor are in transmission connection.
The utility model design principle and effect are: utilize servomotor to pass through synchronous pulley driving mechanism and drive the ball screw rotation, drive piston rod movement through ball nut then, thereby piston rod is done rectilinear motion because of the constraint that receives guide post and fairlead.The rectilinear motion of piston rod produces pressurization.This programme is simple in structure, transmission precision, and reliable operation, cost is low, is suitable as the servo pressing mechanism in the servo torch.
Description of drawings
Accompanying drawing 1 is the servo pressing mechanism front view of the utility model embodiment;
Accompanying drawing 2 is the vertical view of Fig. 1.
In the above accompanying drawing: 1. servomotor; 2. piston rod; 3. ball screw; 4. second synchronizing wheel; 5. guide post; 6. housing; 7. fairlead; 8. ball nut; 9. be with synchronously; 10. first synchronizing wheel.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment: the servo pressing mechanism in a kind of servo torch
As depicted in figs. 1 and 2; This servo pressing mechanism has the piston rod 2 of pressurization together; These piston rod 2 sliding bearings are on a housing 6, and piston rod 2 is fixedly connected with a fairlead 7, and fairlead 7 is enclosed within on the guide post 5; Guide post 5 relative housing 6 positioning supports, the parallel axes of the axis of guide post 5 and piston rod 2.
Said servo pressing mechanism also is provided with a ball wire rod mechanism; This ball wire rod mechanism is made up of ball screw 3 and ball nut 8; Ball nut 8 is fixedly connected with piston rod 2, and ball screw 3 cooperates with ball nut 8, and an end of ball screw 3 links to each other with one second synchronizing wheel 4; Second synchronizing wheel 4 is through be with 9 and 1 first synchronizing wheel 10 to be in transmission connection synchronously, and first synchronizing wheel 10 is fixedly connected with the output shaft of a servomotor 1.
During present embodiment work; Servomotor 1 drives first synchronizing wheel 10 and rotates; First synchronizing wheel 10 rotates through being with 9 and second synchronizing wheel 4 to drive ball screw 3 synchronously; Ball screw 3 drives piston rods 2 motions through ball nut 8, thereby piston rod 2 is owing to receive guide post 5 and rectilinear motion is done in the constraint of fairlead 7, and when welding, plays pressurization.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
