Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal power devices, in particular to a centrifugal power device with adjustable counterweight. Background Art

[0002] The old-fashioned stamping machine includes an electric motor, a V-belt, a large pulley, a transmission shaft, a pinion, a toothed counterweight wheel, a crankshaft, a connecting rod and a slider; the output end of the motor is connected to the large pulley through a V-belt, and a transmission shaft is coaxially connected between the pinion and the large pulley. The motor is fixed to the stamping machine frame, and the transmission shaft is rotatably set on the stamping machine frame. The pinion is engaged with the toothed counterweight wheel, and one side of the toothed counterweight wheel shaft is connected to one end of the crankshaft. Both ends of the crankshaft are rotatably connected to the stamping machine frame, and the middle part of the crankshaft is rotatably connected to the connecting rod sleeve; the working principle of the old-fashioned stamping machine is that when the motor rotates, the large pulley is driven to rotate through the V-belt, and the large pulley drives the toothed counterweight wheel to rotate through the transmission shaft and the pinion. After the counterweight wheel rotates, a large torque is generated to drive the crankshaft to rotate, so that the connecting rod is synchronously moved up and down, driving the connecting rod-linked punch to move up and down to stamp the sheet metal.

[0003] The problem with this old-fashioned punching machine is that the punching force it provides is limited, and the sizes of the large pulley, small gear and toothed counterweight wheel are fixed and cannot be changed after installation. The counterweight of the toothed counterweight wheel cannot be adjusted according to the increase in thickness or hardness of the plate. The torque of the toothed counterweight wheel cannot increase with the increase in thickness or hardness of the plate, which limits the use of the power device of the old-fashioned punching machine. Utility Model Content

[0004] To solve the above problems, the present invention provides a centrifugal power device with adjustable counterweight, which can adjust the device counterweight at any time according to the output torque requirements of the connected power output device (such as a crusher, mixer, punch or centrifuge) to provide corresponding torque output.

[0005] The utility model provides a centrifugal power device with adjustable counterweight, comprising a frame body, an electric motor, a large flywheel, at least one set of adjustable counterweight rotating blades, two rotating pressure seats, a rotating shaft and a first belt;

[0006] The motor is located at the bottom of the frame and provides initial power to the device.

[0007] A large flywheel and a rotary pressure seat are respectively arranged at the lower part of the frame body corresponding to the motor seat, and the rotary pressure seat is arranged at the center position of the lower part of the frame body, and the other rotary pressure seat is coaxially arranged at the corresponding position of the upper part of the frame body. The diameter of the large flywheel is larger than the diameter of the output end of the motor, and the large flywheel is connected to the output end of the motor through a first pulley;

[0008] At least one set of adjustable counterweight rotating blade groups is passed through and fixed in the middle of the rotating shaft, and the upper and lower ends of the rotating shaft are respectively limited and fixed between the two rotating pressure seats, and the rotating shaft can rotate with the rotating pressure seat as the axis. The horizontally rotating adjustable counterweight rotating blades can prevent the detachable counterweight blocks on the vertically rotating counterweight blades from being affected by the earth's gravity to generate a downward external force, which may be loosened from the blades in the reverse direction during repeated circumferential rotation and then splash outward to cause a safety accident. However, the horizontally rotating counterweight blades will not have such a problem. Since the external force of the counterweight blocks affected by the earth's gravity is downward rather than in the horizontal circumferential tangential direction, the detachable counterweight blocks will not rotate backward and loosen during rotation to cause a safety accident; the counterweight blocks on the outer end of each blade arm of the adjustable counterweight rotating blade group can be increased or decreased according to the torque requirements of the output equipment such as the crusher, mixer, punching machine or centrifuge driven by the output end;

[0009] The large flywheel is fixed on the rotating shaft at the output end position of the motor. The large flywheel is connected to the output end of the motor through a first belt. The large flywheel drives the adjustable counterweight rotating blade group on its upper part to rotate through the rotating shaft, so that the torque of the adjustable counterweight rotating blade group can change with the increase or decrease of the counterweight block to adapt to the torque requirements of different output end devices.

[0010] Each set of adjustable counterweight rotating blade groups includes a central support plate, four spiral arm blades and 1-4 counterweight blocks; the central support plate is square or circular, the middle part of the central support plate is passed through and fixed on the rotating shaft, the four spiral arm blades are evenly distributed and fixed on the upper end surface of the central support plate, and 1-4 counterweight blocks are removably fixed on the outer end surfaces of the corresponding number of spiral arm blades. The four spiral arm blades can be screwed with counterweight blocks as needed, or only one blade, two blades or three blades can be screwed with counterweight blocks as needed, so that the adjustable counterweight rotating blade group can generate torque of different sizes when rotating.

[0011] Two spiral arm blades are symmetrically arranged on the front and rear sides corresponding to the upper end surface of the middle support plate, and the other two spiral arm blades are symmetrically arranged on the left and right sides corresponding to the upper end surface of the middle support plate.

The two pairs of long support arm blades are vertically cross-crossed to clamp the middle support plate in between. The two groups of adjustable counterweight rotating blade groups are arranged up and down and coaxially fixed on the rotating shaft. The two groups of adjustable counterweight rotating blade groups are arranged in a vertical position or the two groups of adjustable counterweight rotating blade groups are staggered up and down. The staggered setting of the two groups of adjustable counterweight rotating blade groups can reduce the axial shaking of the rotating shaft, thereby reducing the horizontal shaking of the frame body.

[0014] The two groups of adjustable counterweight rotating blade groups arranged in opposite positions up and down are fixedly connected with each other by fixing bolts; or, the two groups of adjustable counterweight rotating blade groups arranged in opposite positions up and down are fixedly connected with each other by fixing bolts, so as to maintain the stability of the horizontal rotation of the rotary arm blades during the rotation process, reduce the abnormal noise caused by the up and down vibration of a single rotary arm blade and the impact on torque.
