Description

Technical Field

[0001] This invention belongs to the field of hydraulic cylinder manufacturing technology, specifically a drilling device for machining hydraulic cylinders. Background Technology

[0002] In the field of hydraulic cylinder manufacturing, the cylinder end cap is a key component, and its structural design and machining accuracy play a crucial role in the overall performance of the hydraulic cylinder. Among them, opening the oil port on the side of the cylinder end cap is a key process in the production process. The opening position, dimensional accuracy, and surface quality of the oil port directly affect the smoothness of oil flow, sealing performance, and system stability during operation. Therefore, efficiently and accurately completing the drilling of the oil port on the side of the cylinder end cap is an important link in improving the production quality and efficiency of hydraulic cylinders.

[0003] Currently, the drilling process mainly relies on clamps to secure the cylinder end caps. Specifically, before starting the drilling operation, the operator needs to spend a certain amount of time and effort to accurately place the cylinder end cap in the designated position of the clamp, and adjust the clamp manually or mechanically to firmly clamp the cylinder end cap. After completing the drilling of one cylinder end cap, the clamp needs to be readjusted before the next cylinder end cap to be processed is fixed. This repeated clamp adjustment process consumes a lot of time, increasing the complexity and time cost of the operation.

[0004] Therefore, the present invention provides a drilling device for hydraulic cylinder machining. Summary of the Invention

The fixing component is used to press into the pressure groove to limit the end cap body when the worktable is rotated to a horizontal position.

[0007] Preferably, the fixing component includes a connecting plate, which is fixedly installed on the outer wall of the column, a reinforcing plate is fixedly installed between the connecting plate and the column, and a fixing pressure plate is fixedly installed on the inner wall of the connecting plate.

[0008] Preferably, the rotating assembly includes a hydraulic cylinder, which is fixedly installed on the top of the base. A lifting seat is fixedly installed at the end of the hydraulic cylinder away from the base. A drive roller is rotatably installed on the inner wall of the lifting seat. A force-bearing frame is fixedly installed at the bottom of the worktable, and the drive roller is located between the force-bearing frame and the worktable.

[0009] Preferably, the positioning component includes two bonding blocks, both of which are bonded to the worktable. An end positioning plate is fixedly installed between the bonding blocks. The end positioning plate is bonded to the end cover body. A guide component is provided on the top of the base.

[0010] Preferably, the guiding assembly includes an upright plate, which is fixedly installed on the top of the base. A horizontal plate is fixedly installed on the top of the upright plate. Guide rods are symmetrically fixedly installed on the outer wall of the horizontal plate. The worktable and the end positioning plate are slidably connected to the guide rods. A force-bearing plate is fixedly installed on one end of each guide rod. An elastic element is fixedly installed between the force-bearing plate and the end positioning plate, and on the outside of the guide rod. Support rods are symmetrically fixedly installed on the outer wall of the horizontal plate. The support rods are slidably connected to the worktable. The end of the support rod away from the horizontal plate is in contact with the end positioning plate.

[0011] Preferably, the top of the workbench is provided with a plurality of collection slots A, one end of the workbench is provided with a chip removal slot, all collection slots A are connected to the chip removal slot, and a collection component is provided at one end of the workbench.

[0012] Preferably, an extension plate is symmetrically fixedly installed on the top of the workbench, and the two extension plates are respectively attached to two side positioning plates, and a support plate is fixedly installed between the bottoms of the extension plates.

[0013] Preferably, the collection component includes a collection box that fits into the workbench. A plug-in block is symmetrically fixed to the outer wall of the collection box, and each plug-in block is inserted into the inner wall of the workbench. A limit block is inserted between each plug-in block and the workbench.

[0014] Preferably, guide plates are symmetrically fixedly installed on the top of the workbench, and the guide plates are respectively attached to the extension plates. Several collection slots B are opened on the top of the collection box.

[0015] Preferably, a plurality of receiving plates are fixedly installed on the top of each extension plate, and an installation plate is fixedly installed between two corresponding receiving plates, and brush bristles are fixedly installed on the inner wall of each installation plate.

[0016] The beneficial effects of this invention are as follows: 1. The drilling device for hydraulic cylinder processing described in this invention uses a rotating component to drive the worktable to rotate around the rotating seat. When the worktable rotates to a horizontal position, the fixing component enters the inner side of the pressure groove and fits against the end cover body to achieve clamping and fixing of the end cover. This method of clamping by rotating the worktable avoids the cumbersome operation of traditional fixtures that require reciprocating adjustments to achieve fixing, shortens the processing preparation time, and improves the overall production efficiency.

[0017] 2. The drilling device for hydraulic cylinder processing described in this invention has a worktable that is initially tilted. After the end cap body is placed between the two side positioning plates on the worktable, the end cap will automatically slide down the inclined surface under the action of gravity until it is in contact with the positioning component. This process does not require manual and precise adjustment of the end cap position, which greatly saves positioning time. Compared with the traditional method that requires manual positioning one by one, it significantly improves the efficiency of the loading and positioning process. At the same time, during the rotation of the worktable, the end cap body can always be in contact with the positioning component under the action of gravity, thereby ensuring the accuracy of subsequent drilling.

[0018] 3. The drilling device for hydraulic cylinder processing described in this invention achieves automatic material feeding through the cooperation of the guiding component and the positioning component. When the worktable rotates to the initial position, the hydraulic cylinder continues to retract. Due to the restriction of the guiding component, the end positioning plate cannot rotate. During the rotation of the worktable, it loses its blocking effect on the end cap body, and the end cap body slides down the inclined surface of the worktable. This automatic material feeding process is closely connected with automatic positioning and automatic drilling, forming a complete automated production process, which greatly improves production efficiency.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 7As shown in the embodiment of the present invention, a drilling device for hydraulic cylinder processing includes a base 1, a column 2 fixedly mounted on the top of the base 1, a drilling structure 3 mounted on the outer wall of the column 2, a support seat 4 fixedly mounted on the top of the base 1, a rotating seat 5 rotatably mounted between the support seat 4 and the column 2, a worktable 6 fixedly mounted on the top of the rotating seat 5, side positioning plates 7 symmetrically fixedly mounted on the top of the worktable 6, an end cap body 8 disposed between the side positioning plates 7, and a pressure groove 9 formed on the top of each side positioning plate 7. A fixing component and a positioning component are disposed above the worktable 6, and a rotating component is disposed below the worktable 6. The fixing component is used to press into the pressure groove 9 to limit the end cap body 8 when the worktable 6 rotates to a horizontal position. When opening the oil port on the cylinder end cover, the end cover body 8 is placed on the worktable 6 and positioned between the two side positioning plates 7. Initially, the worktable 6 is tilted, and the end cover body 8 will slide down the inclined surface of the worktable 6 under gravity until it is in contact with the positioning component. Then, the rotating component is activated, which pushes the worktable 6 to rotate around the rotating seat 5. As the worktable 6 rotates, it moves the end cover body 8 closer to the fixing component. When the worktable 6 rotates to a horizontal position, the fixing component enters the inner side of the pressure groove 9 and is in contact with the end cover body 8, thereby clamping and fixing the end cover body 8. After the end cover body 8 is clamped, the drilling structure 3 is activated, which drills holes in the end cover body 8, thus completing the process. In the oil outlet opening process, this invention uses a rotating component to drive the worktable 6 to rotate around the rotating base 5. When the worktable 6 rotates to a horizontal position, the fixing component enters the inner side of the pressure groove 9 and fits against the end cap body 8, achieving clamping and fixing of the end cap. This method of clamping by rotating the worktable 6 avoids the cumbersome operation of traditional fixtures that require reciprocating adjustments to achieve fixing, shortens processing preparation time, and improves overall production efficiency. In the initial state, the worktable 6 is set at an inclination. After the end cap body 8 is placed between the two side positioning plates 7 on the worktable 6, the end cap will automatically slide down the inclined surface under the action of gravity until it fits against the positioning component. This process does not require manual and precise adjustment of the end cap position, greatly saving positioning time. Compared to the traditional method that requires manual positioning of each item, this invention significantly improves the efficiency of the feeding and positioning processes. Simultaneously, as the worktable 6 rotates, the end cap body 8 remains in contact with the positioning components under gravity, ensuring the accuracy of subsequent drilling. From the automatic positioning of the end cap, the rotation and clamping of the worktable 6, to the drilling of the drilling structure 3, the entire process is seamless and smooth, requiring minimal manual intervention and pauses between stages. This enables continuous, uninterrupted production, effectively improving equipment utilization and meeting the demands of large-scale production. Compared to the complex clamping and positioning structures of existing technologies, the clamping structure of this invention is simple, easy to drive, and the mechanical limiting method is more reliable; effective limiting can be achieved simply by controlling the rotation of the worktable 6.

[0024] like Figures 2 to 6As shown, the fixing assembly includes a connecting plate 10, which is fixedly installed on the outer wall of the column 2. A reinforcing plate 11 is fixedly installed between the connecting plate 10 and the column 2, and a fixing pressure plate 12 is fixedly installed on the inner wall of the connecting plate 10. The connecting plate 10 is fixed to one side of the column 2. The reinforcing plate 11 increases the connection strength between the connecting plate 10 and the column 2. The fixing pressure plate 12 is fixed above the worktable 6 through the connecting plate 10. When the worktable 6 rotates to a horizontal position, the end cap body 8 will follow the worktable 6 and move closer to the fixing pressure plate 12. When the worktable 6 rotates to a horizontal position, the fixing pressure plate 12 will enter the inner side of the pressure groove 9 and fit against the top of the end cap body 8, thereby achieving automatic clamping and fixing of the end cap body 8. This automatic clamping method does not require manual intervention and can quickly and accurately fix the end cap body 8 on the worktable 6, improving the clamping efficiency and accuracy. It should be noted that in order to ensure the fixing effect of the fixing pressure plate 12, the contact surface between the fixing pressure plate 12 and the end cap body 8 is treated with anti-slip treatment.

[0025] like Figures 1 to 3 and Figure 7 As shown, the rotating assembly includes a hydraulic cylinder 13, which is fixedly installed on the top of the base 1. A lifting seat 14 is fixedly installed at the end of the hydraulic cylinder 13 away from the base 1. A drive roller 15 is rotatably installed on the inner wall of the lifting seat 14. A force-bearing frame 16 is fixedly installed at the bottom of the worktable 6. The drive roller 15 is located between the force-bearing frame 16 and the worktable 6. When the worktable 6 needs to rotate, the hydraulic cylinder 13 will retract. When the hydraulic cylinder 13 retracts, it will drive the lifting seat 14 to rise and fall. When the lifting seat 14 rises and falls, the drive roller 15 will follow. When the drive roller 15 rises and falls, it will push the worktable 6 or pull the worktable 6 through the force-bearing frame 16, thereby realizing the rotation of the worktable 6.

[0026] like Figures 4 to 6 and Figures 8 to 9As shown, the positioning assembly includes two fitting blocks 17, both of which are fitted to the worktable 6. An end positioning plate 18 is fixedly installed between the fitting blocks 17 and is fitted to the end cap body 8. A guide assembly is provided on the top of the base 1. The end positioning plate 18 is positioned at one end of the side positioning plate 7 via the fitting blocks 17. When the end cap body 8 slides down the worktable 6 between the two side positioning plates 7, the end positioning plate 18 will block the sliding end cap body 8. After being blocked, the end cap body 8 will remain fitted to the end positioning plate 18, thereby achieving the positioning of the end cap body 8. Through the provided guide assembly, when the worktable 6 rotates horizontally and returns to its original position, the end positioning plate 18 can follow the rotation and remain at the end of the side positioning plate 7 to limit the end cap body 8. When the worktable 6 returns to its initial position, the liquid... As the pressure cylinder 13 continues to retract, the worktable 6 continues to rotate. At this time, the end positioning plate 18 cannot rotate due to the restriction of the guide component. During the rotation of the worktable 6, the end positioning plate 18 loses its blocking effect on the end cap body 8. After losing the obstruction of the end positioning plate 18, the end cap body 8 slides down the inclined surface of the worktable 6 and is received and transported by external equipment. This invention realizes the automatic feeding function through the cooperation of the guide component and the positioning component. When the worktable 6 rotates back to the initial position, the hydraulic cylinder 13 continues to retract. Due to the restriction of the guide component, the end positioning plate 18 cannot rotate. During the rotation of the worktable 6, it loses its blocking effect on the end cap body 8. The end cap body 8 slides down the inclined surface of the worktable 6. This automatic feeding process is closely connected with automatic positioning and automatic drilling, forming a complete automated production process, which greatly improves production efficiency.

[0027] like Figures 3 to 4 and Figures 8 to 9As shown, the guide assembly includes a vertical plate 19, which is fixedly installed on the top of the base 1. A horizontal plate 20 is fixedly installed on the top of the vertical plate 19. Guide rods 21 are symmetrically fixedly installed on the outer wall of the horizontal plate 20. The worktable 6 and the end positioning plate 18 are both slidably connected to the guide rods 21. A force-bearing plate 22 is fixedly installed on one end of each guide rod 21. Elastic elements 23 are fixedly installed between the force-bearing plate 22 and the end positioning plate 18, and on the outside of the guide rods 21. Support rods 24 are symmetrically fixedly installed on the outer wall of the horizontal plate 20. The support rods 24 are slidably connected to the worktable 6. The end of the support rod 24 away from the horizontal plate 20 is in contact with the end positioning plate 18. The guide rods 21 and support rods 24 are fixed by the vertical plate 19 and the horizontal plate 20. The guide rods 21 provide a precise track for the rotation of the end positioning plate 18. When the worktable 6 rotates to a horizontal position, the worktable 6 pushes the contact block 17 to rotate along with it. The contact block 17 then drives the end positioning plate 18 to rotate along the guide rods 21. The end positioning plate 18 rotates, thus keeping it at the end of the side positioning plate 7 for limiting operation. During this rotation, the end positioning plate 18 compresses the elastic element 23, causing it to contract. When the worktable 6 rotates back to its original position, the end positioning plate 18 will follow the worktable 6 to rotate back to its original position under the reverse elastic force of the elastic element 23, thus preparing for the next drilling operation. After the end positioning plate 18 is reset, it will be in contact with one end of the support rod 24. At this time, the hydraulic cylinder 13 continues to contract, causing the worktable 6 to continue to rotate. The end positioning plate 18 cannot continue to rotate due to the restriction of the support rod 24, so the end positioning plate 18 will move away from the worktable 6. As the distance increases, when the end positioning plate 18 can no longer limit the end cap body 8, the end cap body 8 will slide down the inclined surface of the worktable 6 due to the loss of restriction, thus achieving the effect of automatic unloading. This automatic unloading method does not require manual intervention, improves production efficiency, and reduces errors and safety hazards caused by manual operation.

[0028] like Figures 10 to 11As shown, the top of the workbench 6 has several collection slots A25, and one end of the workbench 6 has a chip removal slot 26. All collection slots A25 are connected to the chip removal slot 26. A collection assembly is provided at one end of the workbench 6. During the drilling operation, the device generates a large amount of debris. After each drilling operation, the workbench 6 tilts to allow the end cap body 8 to be unloaded. When the workbench 6 tilts, the debris on its surface slides down the inclined surface. During this sliding process, the debris is collected by the collection assembly. When debris passes through the collection tank A25, it falls to the inside of the collection tank A25 under the action of gravity. The debris that enters the inside of the collection tank A25 will gather in the chip discharge tank 26 and enter the collection component for collection, realizing the effect of automatic debris handling. This avoids the residue and accumulation of debris on the surface of the workbench 6, prevents debris from flying and spreading on the surface of the workbench 6, and allows operators to work in a relatively clean working environment, reducing the risk of inhaling debris and protecting their health.

[0029] like Figure 10 and Figure 12 As shown, extension plates 27 are symmetrically fixedly installed on the top of the workbench 6. The two extension plates 27 are respectively attached to the two side positioning plates 7. A support plate 28 is fixedly installed between the bottoms of the extension plates 27. The extension plates 27 provide a clear and specific unloading path for the end cap body 8. When the workbench 6 is tilted for unloading, the end cap body 8 slides down the inclined surface of the workbench 6 under the action of gravity. The presence of the extension plates 27 further constrains and guides the movement direction of the end cap body 8, so that it can slide down smoothly according to the predetermined trajectory, avoiding deviation or jamming of the end cap body 8 during the unloading process, and ensuring the smoothness of the unloading process.

[0030] like Figures 10 to 11 and Figure 13 As shown, the collection assembly includes a collection box 29, which is fitted to the workbench 6. Plug-in blocks 30 are symmetrically fixed to the outer wall of the collection box 29, and each plug-in block 30 is inserted into the inner wall of the workbench 6. A limiting block 31 is inserted between each plug-in block 30 and the workbench 6. The collection box 29 is located at the end of the workbench 6 and communicates with the chip discharge groove 26. When debris enters the chip discharge groove 26 through the collection groove A25, the debris slides along the chip discharge groove 26 into the inner side of the collection box 29, thus automatically collecting the debris. The plug-in blocks 30 and limiting blocks 31 facilitate the disassembly of the collection box 29, thereby facilitating the processing of the collected debris.

[0031] like Figure 10 and Figure 13As shown, guide plates 32 are symmetrically fixedly installed on the top of the workbench 6. The guide plates 32 are respectively attached to the extension plates 27. The top of the collection box 29 is provided with several collection slots B33. The guide plates 32 can guide the debris on the workbench 6 and move the debris to the position of the collection slots A25, so as to facilitate the processing of the debris. The guide plates 32, in cooperation with the extension plates 27, block the area outside the two extension plates 27, thereby preventing the debris from sliding off the workbench 6. The edge of the collection slots A25 is aligned with the guide plates 32 to ensure that the debris outside the extension plates 27 can be collected. The collection slots B33 opened on the collection box 29 are located inside the two extension plates 27, thereby increasing the number of collection slots inside the extension plates 27. By increasing the number of collection slots inside the extension plates 27, the effect of processing the debris inside the extension plates 27 is improved.

[0032] like Figure 10 and Figure 12 As shown, several receiving plates 34 are fixedly installed on the top of the extension plate 27, and an mounting plate 35 is fixedly installed between two corresponding receiving plates 34. Brush bristles 36 are fixedly installed on the inner wall of the mounting plate 35. The receiving plates 34 and mounting plates 35 fix the multiple brush bristles 36 on the moving path of the end cap body 8 when it is unloaded. When the end cap body 8 is unloaded, the end cap body 8 will pass under each brush bristle 36 in sequence. The brush bristles 36 clean the top of the end cap body 8 and brush off any debris that may be located on the top of the end cap body 8, thereby improving the debris handling effect.
