Description

Technical Field

[0001] The present application relates to the field of power mechanical devices, and in particular to an arc-shaped hook-type cylinder. Background Art

[0002] In the field of industrial automation, cylinders are widely used in various automation equipment, such as machine tools, packaging machines, printing machines, etc. In the field of industrial automation, cylinders, as key components of internal combustion engines, usually use linear reciprocating motion for power transmission, thereby converting heat energy or pressure energy into mechanical energy to provide power for the device. However, with the widespread use of automation industry, when producing materials with a certain curvature on the surface such as production wire harnesses and pipelines, the traditional cylinders provide linear drive that cannot effectively fix the curved materials. Buckles or cable ties are needed for bundling and fixing, and additional tools are needed for disassembly, which is very troublesome and will also cause wear on the surface of the curved materials. Utility Model Content

[0003] In order to improve the problem that traditional linear drive cylinders have single power transmission and cannot perform targeted fixation of arc-shaped materials, the present application provides an arc-shaped hook cylinder.

[0004] The application provides an arc-shaped hook cylinder adopting the following technical solution:

[0005] An arc-shaped hook-type cylinder comprises a main shell, a rotation groove is opened on one side of the main shell, a piston hole is opened at the bottom of the rotation groove, and a piston rod is movably arranged in the piston hole.

[0006] The main shell is provided with a first rotating rod in the middle of the rotating groove, and a rotating plate is connected to the surface of the first rotating rod. A connecting block is provided on one side of the rotating groove bottom located on the first rotating rod, and the connecting block is elastically connected to the side surface of the rotating plate.

[0007] By adopting the above technical solution, the piston rod moves forward along the piston hole, thereby applying thrust to the rotating plate, causing the rotating plate to tilt. When the rotating plate is tilted, it is plugged into the connecting block, and the subsequent arc block is stretched a second time to facilitate the placement of materials. The piston rod moves backward along the piston hole, causing the rotating plate to tilt in the opposite direction, thereby cooperating with the removal of the connecting block, causing the arc block to contract, thereby fixing the material.

[0008] Preferably, a threaded hole communicating with the piston hole is provided on one side of the bottom of the main shell, and an air inlet is threadedly connected to the threaded hole.

[0009] By adopting the above technical solution, the air inlet thread is installed in the threaded hole to form a fixation, and the compressed air delivered from the outside is transmitted from the threaded hole to the inside of the piston hole to provide power for the movement of the piston rod.

[0010] Preferably, a sealing layer is fixedly provided in the middle of the piston rod, and the outer surface of the sealing layer abuts against the inner wall of the piston hole.

[0011] By adopting the above technical solution, the sealing layer seals the part inside the piston hole, so that the compressed air transmitted by the air intake port generates thrust on the sealing layer, and then transmits the thrust to the piston rod. At the same time, the sealing layer can prevent the engine oil transmitted by the air intake port from entering the cylinder.

[0012] Preferably, a connecting hole is opened in the middle of the rotating plate, and the inner wall of the connecting hole is movably abutted against the surface of the first rotating rod.

[0013] By adopting the above technical solution, the connecting hole abuts against the first rotating rod to form a fixation, so that the rotating plate rotates with the first rotation as the central fulcrum.

[0014] Preferably, a movable groove is provided inside the rotating plate on one side of the connecting hole, and a second rotating rod is fixedly provided on one end of the inner wall of the movable groove away from the connecting hole.

[0015] By adopting the above technical solution, the movable groove reserves space for the subsequent rotation of the connecting rod, and the second rotating rod provides a rotation fulcrum for the subsequent rotation of the rotating seat.

[0016] Preferably, a rotating seat is rotatably provided on the surface of the second rotating rod, a connecting rod is fixedly provided on a side of the rotating seat close to the movable groove, and an arc block is fixedly provided on a side of the rotating seat away from the connecting rod.

[0017] By adopting the above technical solution, the rotating seat connects the connecting rod and the arc block to form a whole, and the rotating seat rotates around the second rotating rod to drive the arc block to fix the material.

[0018] Preferably, a connection port is provided on the outer side of the rotating seat at a position aligned with the connection block, a rubber layer is fixed to one end of the connection block inserted through the connection port, and the side of the rubber layer away from the connection block is fixed to the connection rod.

[0019] By adopting the above technical solution, the rubber layer has a certain degree of deformability, which prevents the connecting block from being staggered when inserted into the connecting port. At the same time, the connecting block applies thrust to the connecting rod to provide power for the rotation of the arc block.

[0020] Preferably, a limiting hole is provided on one side of the rotating groove of the connecting block, a spring is fixed in the limiting hole, and one end of the spring away from the limiting hole is fixedly connected to the side wall of the rotating plate.

[0021] By adopting the above technical solution, when the rotating plate stops applying pressure, the spring rebounds from the limiting hole, thereby applying a thrust to the rotating plate, so that the rotating plate returns to its initial vertical state.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The piston rod is used to push the rotating plate to rotate back and forth, driving the connecting block to push and pull the connecting rod back and forth, so that the arc block swings around the second rotating rod, converting the linear motion transmitted by the piston rod into rotational motion. The arc surface at the bottom of the arc block contacts the surface of the material, effectively fixing the material on the arc surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The embodiment of the present application discloses an arc-shaped hook-type cylinder.

[0033] Example 1

[0034] Reference Figure 1 、 24. An arc-shaped hook cylinder comprises a main shell 1, a rotation groove 2 is provided inwardly on one side of the outer surface of the main shell 1, the rotation groove 2 is divided into two parts, an inclined surface and a vertical surface, and the angle between the inclined surface and the vertical surface is 120°, a piston hole 3 is provided inwardly at the middle of the vertical surface of the rotation groove 2 of the main shell 1, a piston rod 4 is movably inserted in the piston hole 3, and the end of the piston rod 4 facing the rotation groove 2 is conical, a sealing layer 5 is glued and fixed to the middle of the surface of the piston rod 4, the sealing layer 5 is annular as a whole, and the outer surface of the sealing layer 5 abuts against the inner surface of the piston hole 3, a threaded hole 19 is provided at the position where the lower end surface of the main shell 1 is aligned with the piston hole 3, the threaded hole 19 passes through the main shell 1 and is connected with the inside of the piston hole 3, and an air inlet 6 is connected and fixed to the threaded surface of the threaded hole 19.

[0035] It should be noted that the air inlet 6 is hollow inside, and a device for supplying compressed air is connected to the external interface. The sealing layer 5 is made of cast iron or steel, which has high hardness and wear resistance.

[0036] The opening of the rotating groove 2 reserves space for the subsequent movement of the rotating plate 8. At the same time, the air inlet 6 is connected to the outside to transmit compressed air to apply thrust or pull to the piston rod 4, so that the piston rod 4 moves in the piston hole 3, thereby providing power for the swing of the rotating plate 8. The sealing layer 5 is synchronously translated by the movement of the piston rod 4, and the outer surface of the sealing layer 5 fits with the inner wall of the piston hole 3, so that the part of the sealing layer 5 in the piston hole 3 to the bottom of the hole is in a sealed state, preventing gas leakage while avoiding the infiltration of engine oil.

[0037] Reference Figure 2 、 4 , 5, a first rotating rod 7 is fixed on both sides of the middle of the rotating groove 2, and a rotating plate 8 is rotatably connected to the surface of the first rotating rod 7. The bottom of the rotating plate 8 near the piston hole 3 is fixed to the tapered end of the piston rod 4. At the same time, a connecting hole 9 with a width consistent with the diameter of the first rotating rod 7 is opened in the middle of the side surface of the rotating plate 8. The inner wall of the connecting hole 9 is movably plugged into the surface of the first rotating rod 7, so that the rotating plate 8 rotates around the first rotating rod 7 as the center. A movable groove 10 is opened from top to bottom on the upper end surface of the rotating plate 8. A second rotating rod 12 is fixed at the top of the movable groove 10 in the rotating plate 8. A rotating seat 14 is rotatably connected to the surface of the second rotating rod 12. A hook-shaped arc block 13 is fixed on the side of the rotating seat 14 away from the second rotating rod 12. A connecting rod 20 is fixed on the side of the rotating seat 14 away from the arc block 13, and the rod body of the connecting rod 20 is located inside the movable groove 10. It should be noted that under normal conditions, the rotating plate 8 is vertically arranged in the rotating groove 2 (such as Figure 2 shown).

[0038] When the piston rod 4 moves, the tapered end of the piston rod 4 drives the bottom of the rotating plate 8 to translate, and at the same time, the middle part of the rotating plate 8 is connected to the first rotating rod 7, thereby forming a center fixation, so that the rotating plate 8 rotates with the first rotating rod 7 as the center. As the rotating plate 8 transmits the rotational force to the second rotating rod 12, the second rotating rod 12 drives the rotating seat 14 to rotate synchronously, and the rotating seat 14 drives the arc block 13 to rotate, so that the rotating plate 8 and the arc block 13 form an overall swing, thereby changing from a vertical state to an inclined state, which is convenient for fixing materials.

[0039] Reference Figure 2 、 3 , 5. A connecting block 17 is fixedly provided on the middle part of the inclined surface of the rotating groove 2. At the same time, a connecting port 11 is provided on the surface of the rotating plate 8 close to the connecting block 17. The connecting port 11 is aligned with the center of the connecting block 17, and the connecting port 11 passes through the rotating plate 8 and is communicated with the movable groove 10. Under normal circumstances, the surface of the connecting block 17 close to the rotating plate 8 is inserted through the connecting port 11 and fixedly connected to the rod surface of the connecting rod 20, and a rubber layer 18 is fixed at the connection between the connecting block 17 and the connecting rod 20. A limiting hole 15 is provided on one side of the connecting block 17 on the inclined surface of the rotating groove 2. A spring 16 is glued and fixed in the limiting hole 15, and one end of the spring 16 close to the connecting rod 20 is located outside the limiting hole 15, and the end face of the spring 16 located on the outside is fixedly connected to the side wall of the rotating plate 8.

[0040] The rotating plate 8 is pushed by the piston rod 4 to rotate clockwise, so that the upper half of the rotating plate 8 with the first rotating rod 7 as the center rotates clockwise, so that the connecting block 17 is inserted into the connecting port 11, and a thrust is applied to the bottom of the connecting rod 20. The bottom of the connecting rod 20 is driven by the thrust to drive the rotating seat 14 to rotate synchronously, so that the arc block 13 rotates twice to form an expanded state, which is convenient for putting in materials, and under normal circumstances, the connecting block 17 is located outside the rotating plate 8, so that the connecting rod 20 is continuously applied with a pulling force, so that the connecting rod 20 is in a tilted state of 15° counterclockwise, thereby fixing the material. When the piston rod 4 is retracted and stops applying thrust, the spring 16 pops out from the limiting hole 15 to apply thrust to the rotating plate 8, thereby assisting the rotating plate 8 to return to a vertical state.

[0041] The implementation principle of the arc-shaped hook-type cylinder of the embodiment of the present application is as follows: when using the device, first, an external air compression device is connected to the air inlet 6. As the compression device continues to deliver compressed air, the pressure generated is transmitted from the air inlet 6 to the piston hole 3, thereby contacting the rod portion of the piston rod 4 and the side surface of the sealing layer 5, generating a thrust that pushes the piston rod 4 to translate outward along the piston hole 3. At the same time, the sealing layer 5 seals the compressed air, so that the main pressure of the compressed air is applied to the side wall of the sealing layer 5, which helps to enhance the thrust on the piston rod 4.

[0042] The piston rod 4 translates along the piston hole 3 and finally comes into contact with the bottom of the rotating plate 8, and then pushes forward to push the rotating plate 8. The rotating plate 8 rotates clockwise with the first rotating rod 7 as the center, so that the top of the rotating plate 8 is pressed into the inclined surface of the rotating groove 2. As the rotating plate 8 rotates, the distance from the inclined surface of the rotating groove 2 is shortened, so that the connecting block 17 is pressed into the movable groove 10 from the connecting port 11, and the connecting block 17 applies a thrust to the bottom of the connecting rod 20. The connecting rod 20 transmits the thrust to the rotating seat 14, so that the rotating seat 14 rotates clockwise with the second rotating rod 12 as the center, and then drives the arc block 13 to rotate synchronously, forming the rotating plate 8 driving the arc block 13 to rotate with the first rotating rod 7 as the center, and at the same time cooperating with the arc block 13 to perform a second rotation with the second rotating rod 12 as the center, forming an overall bending and unfolding action, which is convenient for placing the material into a fixed range;

[0043] The air compression device stops inputting compressed air and starts extracting it instead. The piston rod 4 moves inward along the piston hole 3, thereby applying a pulling force to the bottom of the rotating plate 8, causing the rotating plate 8 to rotate counterclockwise around the first rotating rod 7, thereby increasing the distance between the rotating plate 8 and the inclined surface of the rotating groove 2, so that the connecting block 17 is pulled out from the connecting port 11, thereby applying a pulling force to the bottom of the connecting rod 20, and the connecting rod 20 transmits the pulling force to the rotating seat 14, thereby causing the rotating seat 14 to rotate counterclockwise around the second rotating rod 12, thereby driving the arc block 13 to contract, forming a clamping action as a whole, thereby abutting and fixing the arc-shaped material.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
