Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic cylinder processing, and particularly to a boring device and method for hydraulic cylinder processing. Background Technique

[0002] Through precise cutting processing, the boring device can effectively remove the rough surface of the inner hole of the cylinder barrel, ensure that geometric parameters such as the diameter, roundness, and coaxiality of the inner hole meet the design requirements, thereby improving the working efficiency and service life of the hydraulic cylinder. In addition, the boring process can also help remove the internal stress brought by processes such as casting or forging, reduce the risk of deformation, and provide a good foundation for subsequent processes such as grinding and polishing. The structure of the boring device usually includes several main parts such as a main shaft, a cutting tool, a support frame, a feeding device, and a cooling system. The main shaft is responsible for rotating the cutting tool and transmitting power, the cutting tool is used for cutting the inner hole of the cylinder barrel, the support frame is used to fix the workpiece, the feeding device controls the feeding speed and amount of the cutting tool, and the cooling system reduces the cutting temperature during the processing to prevent the cutting tool from overheating;

[0003] As disclosed in the patent application publication number CN118577846A, a guiding boring device and method for a hydraulic cylinder include a base, at least two tool bars, and a clamping and positioning device. At least two of the tool bars are arranged in parallel at intervals and can rotate and move simultaneously along the axial direction of the tool bar; a clamping and positioning device for installing and fixing the base to be processed is arranged on the base; a first boring tool and a second boring tool are detachably and fixedly installed on each tool bar; a first installation space for installing the first boring tool is provided outside the first guiding section of the base to be processed, and a second installation space for installing the second boring tool is provided outside the second guiding section of the base to be processed. It aligns the hydraulic cylinder and the boring tool through a lifting assembly to perform boring operations, and can achieve two-way support and guidance for the hydraulic cylinder, enabling the hydraulic cylinder to perform stable boring operations. It can be seen that the existing oil cylinder boring technologies and device operation methods are basically the same, that is, by combining fixing the workpiece, rotating the tool, and cutting processing, the required inner hole shape and size are gradually formed. However, when performing continuous boring operations on the oil inlet hole and oil outlet hole of the hydraulic cylinder using the above technical solution, the staff needs to perform at least two operations of replacing the position and debugging the hydraulic cylinder barrel. That is, after the first boring operation, the staff needs to replace the position and adjust the cylinder barrel for the second boring operation. However, the cylinder barrel of the hydraulic cylinder is a long cylindrical workpiece with high requirements for the depth and length of boring. After each position replacement, the operator needs to re-debug the equipment and set parameters, which will introduce new error factors, such as inaccurate positioning of the fixture, resulting in the final processed two hole positions not being on the same horizontal extension line, making the bored hole positions not meet the design requirements and affecting the performance of the hydraulic cylinder. Moreover, each position replacement requires disassembling and reinstalling the workpiece, adjusting the fixture, setting the tool, etc. These operations not only consume time but also affect the production progress. Especially in the case of mass production, frequent position replacement and debugging will lead to an extended production cycle and reduced overall production efficiency. Summary of the Invention

On both sides of the top of the carrier bracket 1, double-layer fixed clamping members 5 are installed. Inside the double-layer fixed clamping members 5, double-layer sliding clamping members 6 are slidably installed. On one outer wall of the carrier bracket 1, an X-axis conveying and shifting mechanism 2 for driving the double-cylinder position clamping assembly 3 and the cylinder barrel to slide is provided. Inside the carrier bracket 1, a swing-arm type synchronous pushing assembly 7 for driving the two double-layer sliding clamping members 6 in the Y-axis direction to slide towards each other is provided; The side frame 8 is fixed on the outer wall of the other side of the support bracket 1. And a U-shaped frame 9 is installed on the outer wall of the side frame 8 in a lifting manner. On both sides of the top end of the U-shaped frame 9, Y-axis feed assemblies 10 are provided. And a boring assembly 11 is installed on the moving end of the Y-axis feed assembly 10. On the outer wall of one side of the support bracket 1, there is an installation that is electrically connected to the input ends of the X-axis conveying and shifting mechanism 2, the swing-arm type synchronous pushing assembly 7, the Y-axis feed assembly 10, and the boring assembly 11; On the outer wall of one side of the side frame 8, a Z-axis cylinder 12 is installed. The top end of the piston rod of the Z-axis cylinder 12 is fixedly connected to the bottom end of the U-shaped frame 9. The Z-axis cylinder 12 is used to push the U-shaped frame 9, the Y-axis feed assembly 10, and the boring assembly 11 to slide in the Z-axis direction until the central axis of the output shaft of the boring assembly 11 coincides with the horizontal linear reference plane of the cylinder barrel, so as to ensure the machining accuracy of the cylinder barrel hole position.

[0020] The boring method for machining a hydraulic cylinder of this embodiment, like the boring device for machining a hydraulic cylinder described above, includes the following steps: S101: Clean the hydraulic cylinder barrel to be machined, and place the cleaned hydraulic cylinder barrel between the double-layer fixed clamping member 5 and the double-layer sliding clamping member 6. And use the double-cylinder position clamping assembly 3 to ensure that one end of the cylinder barrel is firmly clamped. Subsequently, through the X-axis conveying and shifting mechanism 2, the operator moves the clamped cylinder barrel in the X-axis direction to ensure that the tool of the boring assembly 11 accurately aligns with the predetermined hole position; S102: After confirming that the position is correct, the staff turns on the swing-arm type synchronous pushing assembly 7 to work through the control panel 4. Use the swing-arm type synchronous pushing assembly 7 to make the two double-layer sliding clamping members 6 approach the double-layer fixed clamping member 5 synchronously until the cylinder barrel is firmly fixed. The staff inputs the relevant parameters of boring on the control panel 4, including the Y-axis feed speed, the rotation speed of the boring assembly 11, and the boring depth; S103: After confirming that all the settings are correct, the operator starts the device to start boring machining. The Y-axis feed assembly 10 drives the boring assembly 11 to move in the Y-axis direction until the tool of the boring assembly 11 completes the boring operation on the cylinder barrel; S104: After the first hole is finished being milled, the staff controls the swing - type synchronous pushing assembly 7 through the control panel 4 to work, so that the swing - type synchronous pushing assembly 7 drives the two double - layer sliding clamping parts 6 to move away from the double - layer fixed clamping part 5 synchronously, to relieve the clamping restriction of the cylinder barrel, and uses the X - axis conveying and shifting mechanism 2 to push the double - cylinder - position clamping assembly 3 and the clamped cylinder barrel to continue moving in the X - axis direction until the cylinder barrel is moved to the next hole position. After the cylinder barrel is moved, the swing - type synchronous pushing assembly 7, the double - layer sliding clamping part 6, and the double - layer fixed clamping part 5 continue to clamp and fix the cylinder barrel secondarily, and make the boring assembly 11 and the Y - axis feeding assembly 10 continue to bore holes, so as to form two hole positions on the same horizontal straight line of the cylinder barrel body; S105: After confirming that the machining is correct, the operator uses the control panel 4 to release the clamping state of the double - cylinder - position clamping assembly 3, loosen the fixture and take out the cylinder barrel.

[0021] Embodiment 2, based on Embodiment 1, is given by Figure 4 、 Figure 5 and Figure 6 The double - cylinder - position clamping assembly 3 includes a T - shaped plate 301 installed on the mobile end of the X - axis conveying and shifting mechanism 2, two symmetrically installed extended columns 302 on the outer wall of the T - shaped plate 301 close to one side of the bearing bracket 1, and a four - jaw chuck 303 fixed at one end of the extended column 302 away from the T - shaped plate 301. When using the double - cylinder - position clamping assembly 3 to clamp two cylinders to be machined synchronously, the staff uses the four - jaw chuck 303 to fix one end of the cylinder barrel and ensure its stability, provides a uniform clamping force through the four - jaw chuck 303, avoids workpiece deformation or loosening caused by single - cylinder clamping, and the extended column 302 serves the purpose of increasing the pushing distance of the X - axis conveying and shifting mechanism 2 during this process; The X - axis conveying and shifting mechanism 2 is used to realize the movement of the workpiece in the horizontal direction during the machining process. Its rapid movement can significantly shorten the positioning time of the workpiece and improve the overall machining efficiency; The double - layer fixed clamping part 5 includes two main clamping plates 501 fixed on one side of the top of the bearing bracket 1 and four steel columns 502 installed between the two main clamping plates 501. A triangular notch is provided on the outer wall of the steel column 502 close to the vertical central reference plane of the bearing bracket 1, and a tooth groove is provided on the triangular notch. The extended column 302 and the main clamping plate 501 are both made of components of alloy steel material; The double-layer sliding clamping part 6 includes a guide seat 601 fixed on one of the steel columns 502, sliding rods 602 slidably installed at both ends inside the guide seat 601, and a U-shaped end frame 603 fixed on the same end of the two sliding rods 602. Auxiliary clamping plates 604 are fixed on the outer walls on both sides of the U-shaped end frame 603. Triangular notches are also provided on the outer wall of the auxiliary clamping plate 604 close to the main clamping plate 501. The cylinder to be processed passes through between the main clamping plate 501 and the auxiliary clamping plate 604 in the Y-axis direction. The double-layer design provides a stronger clamping force by increasing the contact area, ensuring that the position of the workpiece does not change during the processing, and the double-layer fixation can effectively reduce vibration and improve the machining surface quality; The swing-arm type synchronous pushing and pressing assembly 7 includes a rectangular cavity 101 provided at one end inside the bearing bracket 1, rotating shafts 702 rotatably installed on both sides inside the rectangular cavity 101, a straight swing arm 704 fixed at the top of the rotating shaft 702, and a straight notch provided on the surface of the straight swing arm 704. A protruding part 705 extending downward is fixed at the bottom end of the U-shaped end frame 603, and the end of the protruding part 705 passes through the straight notch. A reduction motor 701 for driving one of the rotating shafts 702 to rotate is installed at one end inside the bearing bracket 1. A gear 703 is fixed at one end on the surface of the rotating shaft 702, and the two gears 703 are meshed with each other; When the swing-arm type synchronous pushing and pressing assembly 7 is working, the reduction motor 701 is turned on through the control panel 4 to work. Then the rotating power of the reduction motor 701 is transmitted to the two rotating shafts 702 through the gears 703. At this time, the two rotating shafts 702 rotate synchronously in the opposite direction, that is, the two straight swing arms 704 swing towards each other. Since the protruding part 705 is located in the straight notch of the straight swing arm 704, the swinging action of the straight swing arm 704 is converted into a linear motion of the U-shaped end frame 603, the sliding rod 602, and the auxiliary clamping plate 604 in the Y-axis direction, that is, the U-shaped end frame 603 and the auxiliary clamping plate 604 approach the main clamping plate 501 until the auxiliary clamping plate 604 and the main clamping plate 501 stably clamp the cylinder. It ensures the uniform distribution of the clamping force, avoids workpiece deformation caused by local over-tightening or over-loosening, and enables the operator to easily clamp and release, improving the operation convenience.

[0022] Embodiment 3, on the basis of Embodiment 2, by Figure 7 and Figure 8Given that the Y-axis feed assembly 10 includes a belt rail support table 1001 fixed to the top of the U-shaped frame 9, a double-sliding carriage 1002 slidably mounted on the upper surface of the belt rail support table 1001, and a Y-axis hydraulic cylinder 1003 mounted on one outer wall of the U-shaped frame 9. The top of the piston rod of the Y-axis hydraulic cylinder 1003 is fixedly connected to the bottom of the double-sliding carriage 1002. The boring assembly 11 is mounted on the upper surface of the double-sliding carriage 1002. There is a rectangular opening inside the double-sliding carriage 1002, and a connecting seat is slidably mounted inside the rectangular opening. The top of the connecting seat is fixedly connected to the bottom of the double-sliding carriage 1002, and the top of the piston rod of the Y-axis hydraulic cylinder 1003 is fixedly connected to one outer wall of the connecting seat. The Y-axis hydraulic cylinder 1003 pushes the double-sliding carriage 1002 and the boring assembly 11 to slide in the Y-axis direction, so that the tool of the boring assembly 11 forms a hole position on the cylinder barrel, and can be adjusted according to different processing requirements to adapt to workpieces of different thicknesses and materials.

[0023] When the embodiment of the present application is in use, first, the staff cleans the hydraulic cylinder barrel to be processed to ensure that there is no oil stain, rust or other impurities, so as not to affect the processing accuracy. Subsequently, the cleaned hydraulic cylinder barrel is placed between the double-layer fixed clamping member 5 and the double-layer sliding clamping member 6, and the double-cylinder clamping assembly 3 is used to ensure that one end of the barrel is firmly clamped. During this process, the operator needs to pay attention to the symmetry and clamping force of the fixture to prevent the workpiece from shifting during the processing. Subsequently, through the X-axis conveying and shifting mechanism 2, the operator moves the clamped barrel in the X-axis direction to ensure that the tool of the boring assembly 11 accurately aligns with the predetermined hole position. This step requires careful adjustment to ensure the accuracy of each hole position; after confirming that the position is correct, the staff starts the swing-type synchronous pushing assembly 7 to work through the control panel 4. The swing-type synchronous pushing assembly 7 is used to make the two double-layer sliding clamping members 6 approach the double-layer fixed clamping member 5 synchronously until the barrel is firmly fixed. At this time, the staff needs to confirm the clamping state again to ensure that the barrel will not loosen during the processing; the staff inputs the relevant parameters of boring on the control panel 4, including the Y-axis feed speed, the rotation speed of the boring assembly 11, and the boring depth. These parameters need to be reasonably set according to the material characteristics and tool specifications to ensure the processing effect; after confirming that all settings are correct, the operator starts the device to start boring processing. During this process, the Z-axis cylinder 12 will gradually control the Z-axis height of the U-shaped frame 9, the Y-axis feed assembly 10, and the boring assembly 11 according to the set boring parameters, and the Y-axis feed assembly 10 drives the boring assembly 11 to move in the Y-axis direction until the tool of the boring assembly 11 completes the boring operation on the barrel. During the processing, the staff needs to monitor the running state of the device at all times, observe the cutting situation of the tool and the reaction of the workpiece. If any abnormality is found, such as abnormal cutting sound or excessive chips, etc., the processing needs to be immediately paused for inspection and adjustment; after the boring of this hole position is completed, the staff controls the swing-type synchronous pushing assembly 7 to work through the control panel 4, so that the swing-type synchronous pushing assembly 7 drives the two double-layer sliding clamping members 6 to move away from the double-layer fixed clamping member 5 synchronously to release the clamping restriction of the barrel, and the X-axis conveying and shifting mechanism 2 is used to push the double-cylinder clamping assembly 3 and the clamped barrel to continue to move in the X-axis direction until the barrel is moved to the next hole position. After the barrel is moved, the swing-type synchronous pushing assembly 7, the double-layer sliding clamping member 6, and the double-layer fixed clamping member 5 continue to clamp and fix the barrel for the second time, and the boring assembly 11 and the Y-axis feed assembly 10 continue to perform boring, so as to form two hole positions on the same horizontal straight line of the barrel body; after confirming that the processing is correct, the operator releases the clamping state of the double-cylinder clamping assembly 3 through the control panel 4, loosens the fixture and takes out the barrel. After taking out the barrel, the staff needs to clean it to remove the chips and oil stains on the surface for subsequent inspection or assembly.
