Description

Technical Field

[0001] The utility model belongs to the technical field of rotatable oil cylinders, in particular to a large torque rotatable oil cylinder. Background Art

[0002] The hydraulic rotary cylinder is a compact accessory that combines very high torque in a small space through hydraulic pressure. The rotary cylinder has been successfully used in almost all fields requiring limited rotational motion and high torque.

[0003] In the prior art, the rotary cylinder can rotate and move the rotary rod by spiral rotation, and the rotary cylinder is applicable to various mechanical fields. Before use, the rotary cylinder needs to be fixed at a specified position. Since the fixed position needs to be punched, once the punching position deviates, it will cause the installation position of the rotary cylinder to be difficult to match the punching position, making the fixing of the rotary cylinder more troublesome. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a large torque rotatable oil cylinder, comprising an oil cylinder body, an oil injection channel, a piston threaded sleeve, a threaded shaft and a rotating rod, wherein an oil injection channel is welded to the top of the oil cylinder body, a piston threaded sleeve is installed inside the oil cylinder body, the internal threads of the piston threaded sleeve are connected to the threaded shaft, and the end of the threaded shaft is connected to the rotating rod.

[0006] Preferably, a connecting block is welded to the outer side of the cylinder body, the outer side of the connecting block is connected to a rotating rod through a bearing, a bidirectional screw rod is installed inside the connecting block through a bearing, a bevel gear set is installed between the rotating rod and the bidirectional screw rod, and two sets of bevel gears of the bevel gear set are respectively welded to the outer sides of the rotating rod and the bidirectional screw rod.

[0007] Preferably, the outer side of the bidirectional screw rod is threadedly connected with a slider, the outer side of the slider is welded with a moving block, and the end of the moving block is welded with a fixing seat.

[0008] Preferably, a sliding structure is formed between the moving block and the connecting block, and a threaded structure is formed between the sliding block and the bidirectional lead screw.

[0009] Preferably, a mounting block is welded to the top of the oil cylinder body near the oil injection channel, and a sealing ring is installed inside the mounting block.

[0010] Preferably, a return spring is connected inside the mounting block, and one end of the return spring is connected to a clamping block.

[0011] Preferably, a sliding rod is connected to the surface of the clamping block.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When the utility model needs to be fixed, the rotating rod rotates, driving the two sets of bevel gears on the bevel gear set to mesh and rotate, so that the bidirectional screw rotates with the rotation of the rotating rod, and when the slider thread slides, it drives the moving block to move. When the moving block moves, it can slide with the connecting block. When the fixed seat moves to the specified position, the mounting hole on the fixed seat is docked with the slot hole on the mounting position, and the fixed seat can be fixed, so that the oil cylinder body can be quickly installed and fixed. At the same time, the installation position of the oil cylinder body can be adjusted according to actual conditions, thereby improving the practicality of the oil cylinder body.

[0014] 2. When the rotating rod of the utility model moves, it drives the clamping block to move, thereby compressing the reset spring. When the reset spring is compressed to a specified degree, the oil pipe is inserted into the mounting block. When the end of the oil pipe passes through the sealing ring and docks with the fixing seat, the two sets of sliding rods are loosened. When the reset spring is reset, the two sets of clamping blocks squeeze the oil pipe towards each other. The utility model can improve the sealing between the oil pipe and the oil injection channel through the sealing ring and the clamping block, thereby reducing the occurrence of oil leakage between the oil pipe and the oil injection channel.

When the moving block 11 moves, it can slide with the connecting block 6. When the moving block 11 slides, it drives the fixed seat 12 to move. When the fixed seat 12 moves to the specified position, the mounting hole on the fixed seat 12 is docked with the slot hole on the mounting position, and the fixed seat 12 can be fixed, so that the cylinder body 1 can be quickly installed and fixed.
