Abstract
The utility model provides a pneumatic orbit clamping device which is used for overcoming the defects of the prior art, and is firm to clamp, time-saving and effort-saving, and easy to operate. The pneumatic orbit clamping device is designed by abandoning the old mechanical clamping principle design conception and finally determining the pneumatic combined mechanical gear transmission principle by virtue of comprehensive consideration according to the practical situation of the needed clamping force. The pneumatic orbit clamping device has the advantages of being simple in structure, convenient to operate, safe and reliable, and low in cost.
Description
Technical field
The utility model relates to a kind of clamping device, specifically a kind of pneumatic railway clamping device.
Background technology
Track welding workshop is after welding track, need carry out to track the detections such as Performance Detection and welding flaw detection, in testing process, the putting position of track is had to strict requirement, must within the scope of a segment distance, guarantee linearity and the fixing-stable that track is put, can not tremble.In prior art, still adopt the mechanical gripping means of manual helical clamping mode, easily loosening and vibration during this kind of mode grip track, and cannot guarantee the linearity that track is put, and because need operation is wasted time and energy, being not easy to operation, labour intensity increases.
Summary of the invention
The utility model overcomes above-mentioned the deficiencies in the prior art, and a kind of pneumatic railway clamping device firm, time saving and energy saving, easy operating that clamps is provided.The utility model has been abandoned old-fashioned mechanical grip principle design theory, according to the actual conditions of the required clamping force of track, has considered final this pneumatic railway clamping device of having determined with the principle design of pneumatic combination mechanical gear transmission.
The utility model solves the problems of the technologies described above taked technical scheme: a kind of pneumatic railway clamping device, it comprises mounting seat, cylinder and gear jaw, it is characterized in that: in described mounting seat, be provided with cylinder, the piston rod of described cylinder is connected with gear jaw lower end by jaw engaging lug;
In described mounting seat, be provided with gyroaxis bracing frame, on described gyroaxis bracing frame, gyroaxis be set, described gyroaxis is connected with gear jaw middle part by bearing;
Intermeshing by half gear arranging on it between described gear jaw.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side view of the present utility model;
1, mounting seat; 2, cylinder; 3, gear jaw; 4, jaw engaging lug;
5, gyroaxis bracing frame; 6, gyroaxis; 7, bearing; 8, half gear.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, a kind of pneumatic railway clamping device, it comprises mounting seat 1, cylinder 2 and gear jaw 3.In described mounting seat 1, be provided with cylinder 2, the piston rod of described cylinder 2 is connected with gear jaw 3 lower ends by jaw engaging lug 4; In described mounting seat 1, be provided with gyroaxis bracing frame 5, on described gyroaxis bracing frame 5, gyroaxis 6 be set, described gyroaxis 6 is connected with gear jaw 3 middle parts by bearing 7; Described gear jaw 3 is intermeshing by half gear 8 arranging on it.
Pneumatic railway clamping dress adopts a wafer type, and two groups of gear jaws 3 are arranged side by side in mounting seat 1, and two groups of gear jaws connect gyroaxis 6 by bearing 7, form homonymy coaxial between two, relies on respectively jaw engaging lug 4 to connect two cylinders 2.When the rodless cavity of cylinder is connected source of the gas, piston rod stretches out, and does synchronous clamping move by jaw engaging lug promotion gear jaw; Otherwise when the rod chamber of cylinder is connected source of the gas, piston rod retraction, gear jaw is done and is synchronously unclamped action.Because gear jaw adopts the intermeshing transmission operation principle design of half gear, even if two cylinders can not be worked simultaneously, also can guarantee the centering synchronous clamping action of two pairs of gear jaws.Simultaneously can by change cylinder venting pressure regulate the size of clamping force.
The utlity model has advantage simple in structure, easy to operate, safe and reliable and with low cost.
