Abstract
A double hinge joint suspension type oil cylinder system comprises a machine frame and an oil cylinder arranged in the machine frame. The upper end of the oil cylinder is connected to the top of the machine frame through a knuckle bearing, a piston rod of the oil cylinder is connected with a connecting threaded rod, the lower end of the connecting threaded rod is connected with an oil cylinder lug ring knuckle bearing, and the oil cylinder lug ring knuckle bearing is connected with a knife rest. According to the double hinge joint suspension type oil cylinder system, a common gate type hydraulic shear plate oil cylinder is changed to be of a suspension structure from a fixed structure, joints at two ends of the oil cylinder are connected with the machine frame and the knife rest through the knuckle bearings, thus an activity space of the oil cylinder is enlarged, the piston rod of the oil cylinder is in a free state all the time, and fracture of the piston rod is effectively avoided.
Description
Technical field
The utility model relates to mechanical manufacturing field, specifically is a kind of two hinged suspension type cylinder system.
Background technology
Lock formula hydraulic plate shears is a kind of equipment that is applicable to industries such as tubulation, steel construction, steel electric power bar, boats and ships, vehicle, pressure vessel, is high efficiency, high-precision plate straight line cold shearing common apparatus.Common lock formula hydraulic plate shears mainly contains two kinds of structures, and the oil cylinder of small-sized plate shearing machine is connected with the dish spring with knife rest.In, the oil cylinder of large-scale plate shearing machine is connected with connecting plate with oscillating bearing with knife rest.These two kinds of structures all are that oil cylinder is fixed on the frame top, and oil cylinder and knife rest and frame are 1.5 ° of angles.And 1.5 ° of angles are a theoretical value, no matter are processing or assembling, all are difficult to guarantee the accuracy of 1.5 ° of angles, also are difficult for measuring.Even guaranteed 1.5 ° of angles, plate shearing machine is the adjusting play value when cutting the different-thickness plate, and 1.5 ° of angles still can change, and the oil cylinder of common lock formula hydraulic plate shears does not have hunting range all around, in this case, the oil cylinder piston bar very easily ruptures.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of two hinged suspension type cylinder system, to solve the problem that existing common lock formula hydraulic plate shears oil cylinder piston bar very easily ruptures.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of two hinged suspension type cylinder system, comprise frame, be located at the oil cylinder in the frame, described oil cylinder upper end is connected frame top by oscillating bearing, the piston rod of described oil cylinder connects a connecting screw rod, described connecting screw rod lower end connects an oil cylinder earrings oscillating bearing, and described oil cylinder earrings oscillating bearing connects knife rest.
Described connecting screw rod and piston rod are by the first stop pin cross-under.
Described connecting screw rod and oil cylinder earrings oscillating bearing are by the second stop pin cross-under.
The utility model changes common lock formula hydraulic pressure shear oil cylinder into suspended structure by fixed structure, junction, oil cylinder two ends is connected with knife rest with frame with oscillating bearing, the activity space of oil cylinder is increased, and the oil cylinder piston bar is in free state all the time, has avoided the rod fracture problem effectively.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to the accompanying drawings the utility model is described in further details below.
As shown in Figure 1, a kind of two hinged suspension type cylinder system, comprise frame 1, be located at the oil cylinder 2 in the frame 1, oil cylinder 2 upper ends are connected frame 1 top by oscillating bearing 3, the piston rod 4 of described oil cylinder 2 connects a connecting screw rod 5, first stop pin 8 passes connecting screw rod 5 and piston rod 4, makes connecting screw rod 5 and piston rod 4 that relative motion not take place; Described connecting screw rod 5 lower ends are connected with the screw thread position of oil cylinder earrings oscillating bearing 6, and second stop pin 9 passes the screw thread position of connecting screw rod 5 and oil cylinder earrings oscillating bearing 6, the relative motion of restriction connecting screw rod 5 and oil cylinder earrings oscillating bearing 6; The oscillating bearing position of oil cylinder earrings oscillating bearing 6 connects knife rest 7.
Use the plate shearing machine of above-mentioned two hinged suspension type cylinder systems in the course of the work, oil cylinder 2 has certain hunting range in front, rear, left and right, make the piston rod 4 of oil cylinder 2 not suppress strength in the course of the work, has prevented the fracture of piston rod 4; Stop pin 8 prevents piston rod 4 rotations, has avoided oil cylinder 2 and frame 1 to break away from.
Claims (3)
