Abstract
The utility model relates to a screw-on machine driven by electromotion comprising a main grip head, a back grip head and an orbit base that the back grip head moves on. The main grip head adopts an involutes staggered surface clamping mechanism, and the back grip head adopts a palate grillage clamping mechanism. The utility model is characterized in that: the driving gear of the main grip head is connected on the transmission shaft of a speed reduction motor or an adjustable speed motor through a cluster gear. The screw-on machine can be fixedly connected with the palate grillage that is arranged out of the back grip head and provided with a weighted rod and the back grip head; the palate grillage arranged in the back grip head is instead by a friction back grip; the orbit body of one side of the back grip is fixedly provided whit an another back grip head, the palate grillage arranged in the another back grip head is instead by the friction back grip that is in reverse installation with the friction back grip arranged in the first back grip head. The electric screw-on machine adopting the above schemes can be driven by a motor alone, the screwing can also be realized by the combination of electromotion and manually operation, and the utility model has the advantages of simple operation, saving and practicality.
Description
One, technical field: the utility model relates to the thread screw on and-off machine of a kind of thread screw on and-off machine, particularly a kind of motorized motions.
Two, background technology: the main binding clip back-up tong head of the electronic thread screw on and-off machine of use all is to adopt hydraulic drive mode to drive the driven wheel main, that the back-up tong head is interior to implement to tighten and turn at present, because the Hydraulically Operated Equipment price is expensive, the maintenance cost height, and complicated operation makes troubles for the use of thread screw on and-off machine.
Three, summary of the invention: the purpose of this utility model is exactly the problems referred to above that exist at existing thread screw on and-off machine hydraulic driving mode, and a kind of electronic thread screw on and-off machine is provided.It comprises the rail bed composition that main binding clip, back-up tong head and back-up tong head move, main binding clip adopts the staggered curved surface clamp mechanism of involute, the back-up tong head adopts palate plate frame clamping body, and it is characterized in that: the driven wheel of main binding clip is connected the power transmission shaft of reducing motor or buncher by gear train.It can also be provided with weighted lever and fixedly connected with the palate plate frame of back-up tong head outside the back-up tong head capsule; Substitute the clamping body of palate plate frame and palate plate composition with the friction back-up tong; Be installed with another back-up tong head on the track body of the first side of back-up tong, the palate plate frame in the back-up tong head substitutes with the friction back-up tong, and oppositely installs with the friction back-up tong in first back-up tong head.
Adopting the electronic thread screw on and-off machine after above-mentioned several scheme, can use Motor Drive separately, also can be electronicly and manual to twist button in conjunction with realizing, has effect easy and simple to handle, economical and practical.
Four, description of drawings:
Fig. 1 is the appearance assumption diagram of a kind of embodiment of the present utility model;
Fig. 2 is the appearance assumption diagram of another kind of embodiment;
Fig. 3 is the structure enlarged drawing of the friction back-up tong among the figure.
Five, the specific embodiment:
Contrast accompanying drawing 1, it comprises rail bed 5 compositions of main binding clip 2, back-up tong head 3 and back-up tong head track body 6, and main binding clip 2 adopts the staggered curved surface clamp mechanism of involutes, and back-up tong head 3 adopts palate plate frame clamping bodies.On the basis that does not change original structure, the driven wheel of main binding clip 2 is connected by gear train on the power transmission shaft of reducing motor 1 (or buncher), substitutes hydraulic drive mechanism.Outside back-up tong head 3 shells, be provided with weighted lever 4 and fixedly connected, manually move weighted lever 4 and substitute original hydraulic drive mechanism, realize that the chucking of pipe fitting is fixed with the palate plate frame of back-up tong head 3.
Contrast accompanying drawing 2 and Fig. 3, be installed with another back-up tong head 14 on the track body 6 of back-up tong head 3 one sides, palate plate frame and palate plates in the back-up tong head 3 and 14 are removed, and substitute with friction back-up tong 8, and two interior friction back-up tongs 8 of back-up tong head are oppositely installed.In the outside of back-up tong head 14 pipe pressure clamp 7 is installed, can effectively prevents moving of pipe fitting.
Claims (5)
