[0002] Hydraulic cylinders are the core actuators in hydraulic systems. Their function is to convert hydraulic energy into mechanical energy to drive the load to complete linear reciprocating motion or short-distance oscillation.

[0003] Chinese patent CN144869040U discloses a product processing cutting device. The workpiece is placed on a placement mesh plate, a clamping cylinder pushes the clamping plate to move, and a clamping pad clamps the workpiece. An adjusting cylinder pushes the protective cover downward, and a cutting motor drives the cutting head to rotate to cut the surface of the workpiece. The rotating motor facilitates the rotation and adjustment of the workpiece and facilitates cutting operations on other surfaces of the workpiece.

[0004] However, in this scheme, the position of the cutting motor is fixed, and the workpiece can only be processed by lifting. During the processing of the hydraulic cylinder, the workpiece can only be fixed by the clamping plate. During the cutting of the hydraulic cylinder, high-frequency vibration will inevitably be generated. The two clamping plates are difficult to fix the workpiece under high-frequency vibration, which makes it easy to cause processing errors when cutting the hydraulic cylinder. Utility Model Content

[0022] Example 1

[0023] like Figures 1-3As shown, the cylinder head cutting device for hydraulic cylinder machining in this embodiment includes a base 1. A front support platform 2 is installed at the front end of the base 1, and a rear support platform 3 is installed at the rear end of the base 1. The front support platform 2, the base 1, and the rear support platform 3 together form the core support assembly. A rotating disk 10 is rotatably mounted at the rear center of the front support platform 2. A four-jaw chuck 11 is mounted on the outer end of the rotating disk 10, which is existing technology and is used to clamp the workpiece to be machined in four positions. A drive device is installed inside the front support platform 2 and connected to an external power source. The output end of the drive device is connected to the rotating disk 10, and the drive device drives the rotating disk 10 to rotate. When the rotating disk 10 rotates, it drives the four-jaw chuck 11 to rotate. The front end of the rear support platform 3 is longitudinally symmetrically mounted with... Two first active push rods 18 are provided, and each of the two first active push rods 18 is equipped with a clamping plate 12. Several threaded through grooves 13 are equally spaced on the upper end of the clamping plate 12. A cutting tool is clamped between two threaded through grooves 13. The cutting tool is an existing device, and the cutting tool used may vary depending on the cutting requirements. By placing the cutting tool inside the two clamping plates 12, placing the bolt inside the threaded through grooves 13, and moving the bolt toward the cutting tool, the cutting tool is limited and clamped by the bolt. Finally, the first active push rods 18 drive the clamping plates 12 to move, thereby driving the cutting tool toward the cylinder. The rotating disk 10 drives the four-jaw chuck 11 and the internal cylinder to rotate, thus cooperating with the cutting tool to complete the cutting function.

[0024] Specifically, an extension plate 8 is installed on the upper front end of the front support platform 2, and multiple water spray nozzles 9 are installed on the lower end of the extension plate 8. The water spray nozzles 9 are connected to an external water source through a water pump and pipes. During the cutting process, water is sprayed onto the cutting position through the multiple water spray nozzles 9 to cool down the temperature generated during cutting and ensure the cutting function.

[0025] Furthermore, a driven rod 15 is installed on each of the two first active push rods 18 at the front end of the rear support platform 3. The front ends of the two driven rods 15 are connected to the clamping plate 12 at the same horizontal level. The two driven rods 15 are sleeved inside the rear support platform 3. When the first active push rod 18 drives the clamping plate 12 to move, the two driven rods 15 will move synchronously. The two driven rods 15 and the rear support platform 3 are slidably connected, which can guide and limit the movement trajectory of the clamping plate 12. When installing the tool, the tool needs to be placed between the two clamping plates 12. According to the position of the tool, the connecting bolt is rotated through the threaded through groove 13 above to apply pressure to the tool and complete the clamping of the tool. According to the user's needs, multiple different tools can be installed for processing at the same time. The specific number can be adjusted according to the user's needs.

[0026] The method of use in this embodiment is as follows: First, gently place the hydraulic cylinder body to be processed into the four-jaw chuck 11 of the front support platform 2, start the drive device, then place the matching tool between the two clamping plates 12 of the rear support platform 3, insert the bolt and tighten it, and the tool is stably clamped by the bolt compression. At the same time, the driven rod 15 slides along the rear support rod to guide the tool until the tool is aligned with the part to be cut on the cylinder head. After starting the processing, turn on the drive device to make the rotating disk 10 rotate at a constant speed to drive the cylinder body to rotate, and simultaneously advance the first active push rod 18. The tool completes the cutting as the cylinder body rotates. During the process, the water pump supplies water and the water spray nozzle 9 continuously sprays water to cool it down. After the processing is completed, turn off the drive and push rod, loosen the bolt, remove the tool, and take out the workpiece to complete the operation.

[0027] Example 2

[0028] The structure of the piston for the hydraulic cylinder in this embodiment is basically the same as that of the cylinder head cutting device for hydraulic cylinder machining in Embodiment 1. The difference is that: a moving assembly 4 is installed on the upper end of the base 1. Two telescopic shafts 5 are symmetrically installed inside the moving assembly 4. A clamping arc plate 6 is installed at one end of the two telescopic shafts 5 facing each other. This is used for machining long cylinders and provides auxiliary support. The moving assembly 4 includes a moving plate 401 and a longitudinal plate 402. The moving plate 401 is slidably connected to the upper end of the base 1. Two longitudinal plates 402 are symmetrically installed at the upper edge of the moving plate 401. A telescopic shaft 5 is rotatably installed on the inner side of each longitudinal plate 402. A driving device is installed inside any one of the longitudinal plates 402. The output end of the driving device is connected to the telescopic shaft 5 through a turntable. The rear support platform 3 A guide rod 17 is installed at the front end of the rear support platform 3. One end of the guide rod 17 is fixedly connected to the front support platform 2, and the guide rod 17 is slidably connected to the moving component 4. A second active push rod 14 is installed on the outer side of the guide rod 17 at the front end of the rear support platform 3. One end of the second active push rod 14 is fixedly connected to the side wall of the moving component 4. The second active push rod 14 drives the moving plate 401 in the moving component 4 to move inside the base 1. The drive device inside any one of the longitudinal plates 402 can drive the telescopic shaft 5 to rotate. It should be noted that when the two clamping arc plates 6 clamp the internal cylinder, when the drive device drives any one of the telescopic shafts 5 to rotate, it will drive the cylinder, the two clamping arc plates 6 and the other telescopic shaft 5 to rotate synchronously, thereby changing the direction of the cylinder (see Figure 4 ).

[0029] Furthermore, both the lower ends of the moving component 4 and the rear support platform 3 are provided with water channels 16, and the rear end of the rear support platform 3 is equipped with a water tank 7. The water channels 16 are connected to the water tank 7. During cutting, the cooling water will fall onto the upper end of the base 1 and flow into the interior of the water tank 7 through the two water channels 16 for storage.

[0030] The method of use in this embodiment is as follows: First, gently place the cylinder body between the two clamping arc plates 6 of the moving component 4, start the drive device in any of the longitudinal plates 402, drive the telescopic shaft 5 to rotate and clamp the cylinder body, and then push the moving component 4 to slide along the guide rod 17 through the second active push rod 14 to adjust the lateral position of the cylinder body and the tool. When it is necessary to change the processing direction, drive the telescopic shaft 5 to rotate again, and the cylinder body and the clamping arc plate 6 will rotate synchronously to the target angle. After the tool is installed, the water spray nozzle 9 continuously cools down during the cutting process. The water flows through the water channel 16 at the upper end of the base 1 and enters the water tank 7 at the rear end of the rear support platform 3 for storage. After the processing is completed, turn off the push rod and the drive device, loosen the bolts to remove the tool, and release the cylinder body by loosening the clamping arc plate 6.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
