Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, and in particular to a helical swing hydraulic cylinder with adjustable rotation angle. Background Technology

[0002] The working principle of the spiral swing cylinder is that when the hydraulic control system injects hydraulic oil into the cylinder, the hydraulic oil will push the piston to move linearly in the cylinder. Since the piston and the cylinder are meshed by a helical thread, when the piston moves linearly, the piston will also rotate under the action of the thread, which will drive the output shaft connected to the piston to rotate together, thereby realizing the conversion of the linear motion of the piston into the swing motion of the output shaft.

[0003] A search revealed a patent with application number 202020181159.9, which discloses a helical oscillating cylinder comprising a cylinder body, a piston, and a drive shaft. This patent converts the piston's helical motion into rotation of the drive shaft by injecting hydraulic oil into the cylinder body. However, existing helical oscillating cylinders have a fixed rotation angle, making it impossible to flexibly adjust the rotation angle according to different work tasks, thus failing to meet diverse production needs. Furthermore, long-term operation of the helical oscillating cylinder leads to increased surface temperature and the inability to dissipate heat quickly, severely affecting its normal use and working efficiency, and reducing its service life.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, referring to Figure 1-2 A helical swing cylinder with adjustable rotation angle includes a base 1 and an angle adjustment mechanism;

[0025] In this embodiment, a spiral swing cylinder body 2 is fixedly connected to the top outer wall of the base 1. Two oil inlets 3 are symmetrically provided on the top of the spiral swing cylinder body 2. A main controller 6 is fixedly installed on the side wall of the base 1.

[0026] When the helical swing cylinder is working: hydraulic oil is injected into the left oil port 3 through the external hydraulic control system to push the piston in the cylinder to move backward, thereby causing the helical shaft to rotate in the forward direction; conversely, hydraulic oil is injected into the right oil port 3 to push the piston in the cylinder to move forward, thereby causing the helical shaft to rotate in the reverse direction.

[0027] Specifically, the angle control mechanism includes an angle sensor 4 installed on the spiral shaft of the spiral swing cylinder body 2 and two oil injection solenoid valves 5 installed sequentially on two oil injection ports 3. The angle sensor 4 and the two oil injection solenoid valves 5 are all electrically connected to the main controller 6.

[0028] In this embodiment, when adjusting the angle, simply input the desired rotation angle value into the main controller 6. As hydraulic oil is continuously injected, the spiral shaft rotates continuously. When the angle sensor 4 installed on the spiral shaft detects the desired rotation angle, it transmits a stop signal to the main controller 6, which then controls the corresponding oil injection solenoid valve 5 to close, ensuring the oil injection work stops. At this time, the rotating shaft will stop rotating. In this way, through the intelligent collaborative cooperation between the angle sensor 4, the oil injection solenoid valve 5, and the main controller 6, the rotation angle of the spiral swing cylinder can be flexibly adjusted according to different work tasks, making it easier to meet diverse production needs.

[0029] Example 2, refer to Figure 1-5This embodiment is an optimization based on embodiment 1, specifically: a spiral swing cylinder with adjustable rotation angle, and also includes a cooling mechanism;

[0030] In this embodiment, the cooling mechanism includes a temperature-conducting plate 7 fixedly connected to the top outer wall of the spiral swing cylinder body 2, a temperature sensor 8 fixedly installed on the top outer wall of the temperature-conducting plate 7, a reciprocating air blowing assembly, and a drive assembly.

[0031] Furthermore, the reciprocating blower assembly includes a reciprocating screw 9 rotatably mounted on the base 1, a reciprocating slider 10 adapted to be mounted on the reciprocating screw 9, an L-shaped connecting pipe fixedly connected to the upper outer wall of the reciprocating slider 10, a hollow blower ring 11 fixedly connected to the top of the L-shaped connecting pipe, an air supply box 12 fixedly connected to the bottom of the L-shaped connecting pipe, an air supply fan 13 fixedly mounted on one outer wall of the air supply box 12, and a slide 19 opened on the bottom inner wall of the base 1.

[0032] Furthermore, the lower outer wall of the reciprocating slider 10 is slidably connected to the inner wall of the slide rail 19, which can ensure the stability of the linear motion of the reciprocating slider 10. The hollow blower ring 11 is provided with evenly distributed blower holes 14, which can blow cold air evenly onto the surface of the spiral swing cylinder body 2.

[0033] Furthermore, the drive assembly includes a fixed cover 15 fixedly connected to the outer wall of the other side of the base 1, a motor 16 fixedly mounted on one side of the outer wall of the fixed cover 15, a driving bevel gear 17 fixedly mounted on the output shaft of the motor 16, and a driven bevel gear 18 fixedly mounted on one end of the reciprocating screw 9. The output shaft of the motor 16 passes through one side of the fixed cover 15, and the driving bevel gear 17 and the driven bevel gear 18 mesh with each other.

[0034] In this embodiment, the temperature sensor 8, the motor 16, and the fan 13 are all electrically connected to the main controller 6;

[0035] In this embodiment, when the temperature sensor 8 senses that the surface temperature of the temperature-conducting plate 7, which is attached to the surface of the spiral swing cylinder body 2, is abnormal, a cooling signal will be transmitted to the main controller 6, which will then control the motor 16 and the fan 13 to start reciprocating cooling.

[0036] Secondly, the cold air is sent from the air box 12 into the L-shaped connecting pipe by the air supply fan 13. Then the cold air flows from the L-shaped connecting pipe into the hollow air ring 11 and is finally blown onto the surface of the spiral swing cylinder body 2 by the air blowing holes 14 evenly distributed on the surface.

[0037] Finally, the reciprocating screw 9 is driven to rotate by the motor 16. Under the limit of the slide rail 19, the reciprocating slider 10 matched with the reciprocating screw 9 will drive the hollow blower ring 11 to reciprocate in the surface area of ​​the spiral swing cylinder body 2. In this way, the reciprocating hollow blower ring 11 can uniformly cool the surface of the spiral swing cylinder body 2, ensuring the normal use and working efficiency of the spiral swing cylinder and helping to extend the service life of the spiral swing cylinder.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
