Description

Technical Field

[0001] This invention relates to the field of boring technology, and more specifically to an intelligent machining equipment for boring pressure vessels. Background Technology

[0002] Pressure vessels are widely used in many industrial sectors such as petroleum, chemical, and energy. Their cylinders typically require several holes for installing various equipment or connecting pipelines. After initial drilling, these holes usually require subsequent boring to ensure that the hole diameter accuracy, surface roughness, and hole position meet design requirements, thereby ensuring the sealing performance and structural safety of the pressure vessel during use.

[0003] Most existing on-site boring equipment relies on manual or semi-automatic operation, requiring manual adjustment of tool position and feed rate. This not only results in low processing efficiency but also significantly impacts machining quality due to the operator's skill level, making it difficult to guarantee consistent dimensions across multiple holes. Furthermore, during boring, the cutting force on the tool easily causes vibration and misalignment, and existing equipment generally lacks effective positioning and locking mechanisms, leading to insufficient machining stability. This results in surface defects such as vibration marks and dimensional deviations on the hole walls, severely affecting the assembly accuracy and service life of pressure vessels. Simultaneously, the low level of automation in existing equipment hinders rapid positioning and continuous machining of multiple holes, resulting in a long overall processing cycle and failing to meet the demands of modern manufacturing for efficient and intelligent machining. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an intelligent machining equipment for boring pressure vessels to solve the problems existing in the background art.

A motion mechanism is mounted on the mounting frame, and a boring mechanism and a positioning mechanism are mounted on the motion mechanism. The linear motion module drives the mounting frame to move linearly in the horizontal direction to achieve switching between different axial machining positions. The mounting frame supports the motion mechanism and provides an annular guide and circumferential positioning reference. The motion mechanism drives the boring mechanism to move along an annular trajectory. The boring mechanism is used to perform boring machining on holes in the pressure vessel. The positioning mechanism locks the boring mechanism relative to the mounting frame during the boring process to suppress boring vibration and maintain machining stability.

[0006] Preferably, the mounting bracket has a guide groove on its inner side and a positioning groove on its outer side, and a toothed ring is also fixedly mounted on the mounting bracket.

[0007] Preferably, the motion mechanism includes a guide frame and a fixed frame, the guide frame is slidably installed in the guide groove, the fixed frame is located outside the mounting frame, and the fixed frame and the guide frame are fixedly connected.

[0008] Preferably, a first motor and a reducer are fixedly installed on the side of the fixed frame away from the guide frame, and a rotating shaft is also rotatably installed on the side of the fixed frame away from the guide frame. A gear is fixedly installed on the surface of the rotating shaft. The output end of the first motor is fixedly connected to the input end of the reducer, and the output end of the reducer is fixedly connected to one end of the rotating shaft. The gear meshes with the gear ring.

[0009] Preferably, the boring mechanism includes a second motor, a sliding rod, and a movable frame. The second motor is fixedly mounted on the guide frame, and a threaded rod is fixedly connected to the output end of the second motor. One end of the sliding rod is fixedly connected to the guide frame, and the movable frame is threadedly mounted on the surface of the threaded rod and slidably mounted on the surface of the sliding rod.

[0010] Preferably, an extension frame is fixedly installed on the side of the movable frame away from the guide frame, a third motor is fixedly installed on the side of the extension frame away from the movable frame, a boring head is fixedly installed at the output end of the third motor, and a roller is rotatably installed on the movable frame.

[0011] Preferably, the positioning mechanism includes a main hydraulic cylinder, a piston rod, a secondary hydraulic cylinder, and a connecting rod. The main hydraulic cylinder and the guide frame are fixedly connected by a first support frame, and the secondary hydraulic cylinder and the guide frame are fixedly connected by a second support frame.

[0012] Preferably, a main piston is provided inside the main hydraulic cylinder, and the main piston and the main hydraulic cylinder form a sealed sliding guide fit. One end of the piston rod is fixedly connected to the main piston, and the other end of the piston rod passes through the inner wall of the main hydraulic cylinder and extends outward. A receiving frame is fixedly connected to the other end of the piston rod. A triggering inclined surface and a stabilizing plane are provided on the receiving frame, and a compression spring is sleeved on the surface of the piston rod.

[0013] Preferably, the auxiliary hydraulic cylinder is provided with an auxiliary piston, and two auxiliary pistons are symmetrically arranged. The auxiliary pistons and the auxiliary hydraulic cylinder form a sealed sliding guide fit. Two connecting rods are provided corresponding to the auxiliary pistons. One end of the connecting rod is fixedly connected to the auxiliary piston, and the other end of the connecting rod passes through the inner wall of the auxiliary hydraulic cylinder and extends outward. The other end of the connecting rod is fixedly connected to a brake caliper, which is located in a positioning groove. An auxiliary spring is sleeved on the surface of the connecting rod.

[0014] Preferably, the main hydraulic cylinder is provided with an outlet nozzle, and the auxiliary hydraulic cylinder is provided with an inlet nozzle, and the outlet nozzle and the inlet nozzle are fixedly connected by a guide pipe.

[0015] The beneficial effects of this invention are: In this invention, the linear motion module and the motion mechanism work together. The first motor drives the gear to mesh along the gear ring, and with the sliding constraint of the guide frame in the guide groove, the boring mechanism achieves precise movement and circumferential positioning along the annular trajectory. The second motor drives the screw drive to achieve axial feed of the boring head, so that the tool can accurately reach the preset processing position. This enables continuous and automated boring of holes at different locations on the pressure vessel, reducing manual intervention and auxiliary adjustment time, and effectively improving the efficiency of multi-hole processing. In addition, this invention designs a positioning mechanism with hydraulic linkage. When the movable frame of the boring mechanism drives the roller to move forward, the roller passes sequentially through the triggering inclined surface and the stabilizing plane on the receiving frame. During the triggering stage, the squeezing action of the inclined surface drives the main piston to compress the hydraulic oil, which in turn transmits the hydraulic pressure through the guide pipe to make the two auxiliary pistons in the auxiliary hydraulic cylinder move outward synchronously, pushing the brake caliper to make tight contact with the inner wall of the positioning groove from both sides, thereby achieving the locking between the boring mechanism and the mounting frame during the machining process. When the roller enters the stabilizing plane, the positioning mechanism remains locked, effectively suppressing the vibration and displacement caused by the fluctuation of cutting force during boring, ensuring the surface quality and dimensional accuracy of the hole wall. When the movable frame retracts after machining, the roller disengages from the stabilizing plane, and the compression spring and auxiliary spring automatically reset to release the brake caliper. The entire positioning and unlocking process does not require additional control components, which simplifies the equipment structure and improves the positioning response speed and reliability. In addition, this invention integrates motion drive, boring feed and automatic locking positioning on the same mounting frame, with a compact overall structure and small footprint, which facilitates rapid deployment and flexible processing on pressure vessels on site. It breaks through the bottleneck of traditional large machine tools being limited by site and workpiece size, has good adaptability, and meets the intelligent and efficient requirements of on-site boring processing of large pressure vessels.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1 to 2This invention provides an intelligent machining equipment for boring pressure vessels, including a linear motion module 1 and a mounting frame 2. A motion mechanism 3 is mounted on the mounting frame 2, and a boring mechanism 4 and a positioning mechanism 5 are mounted on the motion mechanism 3. The linear motion module 1 drives the mounting frame 2 to move linearly in the horizontal direction to achieve switching between different axial machining positions. The mounting frame 2 supports the motion mechanism 3 and provides an annular guide and circumferential positioning reference. The motion mechanism 3 drives the boring mechanism 4 to move along an annular trajectory. The boring mechanism 4 is used to perform boring machining on holes in the pressure vessel. The positioning mechanism 5 is used to lock the boring mechanism 4 relative to the mounting frame 2 during the boring process to suppress boring vibration and maintain machining stability.

[0029] Reference Figures 1 to 5 The mounting bracket 2 has a guide groove 21 on its inner side and a positioning groove 23 on its outer side. A gear ring 22 is also fixedly mounted on the mounting bracket 2. The guide groove 21 provides precise sliding guidance for the motion mechanism 3, and the positioning groove 23 facilitates subsequent locking and positioning. The gear ring 22 meshes with the gear 36 to achieve circular trajectory movement, providing a basis for the circumferential positioning of the boring mechanism 4.

[0030] The motion mechanism 3 includes a guide frame 31 and a fixed frame 32. The guide frame 31 is slidably installed in the guide groove 21, and the fixed frame 32 is located outside the mounting frame 2 and is fixedly connected to the guide frame 31. A first motor 33 and a reducer 34 are fixedly installed on the side of the fixed frame 32 away from the guide frame 31. A rotating shaft 35 is also rotatably installed on the side of the fixed frame 32 away from the guide frame 31. A gear 36 is fixedly installed on the surface of the rotating shaft 35. The output end of the first motor 33 is fixedly connected to the input end of the reducer 34, and the output end of the reducer 34 is fixedly connected to one end of the rotating shaft 35. The gear 36 meshes with the gear ring 22. The first motor 33 drives the gear 36 to mesh along the gear ring 22 via the reducer 34. With the sliding constraint of the guide frame 31 in the guide groove 21, the boring mechanism 4 achieves precise movement and circumferential positioning along a circular trajectory, and the self-locking function of the first motor 33 ensures that the position is fixed.

[0031] In use, the linear motion module 1 pulls the mounting frame 2 to move linearly in the horizontal direction. The motion mechanism 3, boring mechanism 4 and positioning mechanism 5 also move synchronously with the mounting frame 2. When the mounting frame 2 reaches the preset position, the first motor 33 drives the rotating shaft 35 to rotate around its own axis through the reducer 34. The rotating shaft 35 rotates and drives the gear 36 to rotate synchronously around the axis of the rotating shaft 35. While rotating, the rotating shaft 35 moves synchronously along the gear ring 22. At the same time, the guide frame 31 slides synchronously along the guide groove 21. The first motor 33 can make the guide frame 31 slide in two different directions by rotating forward or backward. In addition, the self-locking function of the first motor 33 ensures that the guide frame 31 remains fixed after reaching any position.

[0032] In summary, through the cooperation of linear motion module 1 and mounting frame 2, the equipment can be rapidly moved along the axis of the pressure vessel cylinder, facilitating the sequential processing of holes at different axial positions. The guide groove 21 on the inner side of mounting frame 2 slides with guide frame 31, and the gear ring 22 fixed on the outer side meshes with gear 36. With the cooperation of the first motor 33 and reducer 34 on the fixed frame 32, the gear 36 can be driven to move smoothly along the gear ring 22. At the same time, the guide frame 31 is constrained by the guide groove 21, enabling the boring mechanism 4 to move along a precise circular trajectory, achieving rapid positioning at any position in the circumference. The entire motion process is completed by mechanical meshing and sliding guidance, reducing the time for manual adjustment and providing a foundation for the automated continuous boring process, thus improving the overall efficiency and intelligence level of on-site boring of pressure vessels.

[0033] Reference Figures 1 to 9 The boring mechanism 4 includes a second motor 41, a sliding rod 43, and a movable frame 44. The second motor 41 is fixedly mounted on the guide frame 31, and a threaded rod 42 is fixedly connected to the output end of the second motor 41. One end of the sliding rod 43 is fixedly connected to the guide frame 31. The movable frame 44 is threaded onto the surface of the threaded rod 42 and slidably mounted on the surface of the sliding rod 43. An extension frame 45 is fixedly mounted on the side of the movable frame 44 away from the guide frame 31, and a third motor 46 is fixedly mounted on the side of the extension frame 45 away from the movable frame 44. A boring head 47 is fixedly mounted on the output end of the third motor 46, and a roller 48 is rotatably mounted on the movable frame 44. The second motor 41 drives the threaded rod 42 in conjunction with the sliding rod 43 to achieve stable axial feed of the movable frame 44, while the third motor 46 independently drives the boring head 47 to rotate. The feed and cutting are controlled separately, improving machining flexibility and accuracy.

[0034] The positioning mechanism 5 includes a main hydraulic cylinder 51, a piston rod 52, an auxiliary hydraulic cylinder 55, and a connecting rod 56. The main hydraulic cylinder 51 and the guide frame 31 are fixedly connected by a first support frame 511, and the auxiliary hydraulic cylinder 55 and the guide frame 31 are fixedly connected by a second support frame 551. A main piston 53 is provided inside the main hydraulic cylinder 51, and the main piston 53 and the main hydraulic cylinder 51 form a sealed sliding guide fit. One end of the piston rod 52 is fixedly connected to the main piston 53, and the other end of the piston rod 52 passes through the inner wall of the main hydraulic cylinder 51 and extends outward. A receiving frame 54 is fixedly connected to the other end of the piston rod 52. The receiving frame 54 is provided with a triggering inclined surface 541 and a stabilizing plane 542. A compression spring is sleeved on the surface of the piston rod 52. 521. A secondary piston 57 is installed inside the secondary hydraulic cylinder 55. Two secondary pistons 57 are symmetrically arranged, forming a sealed sliding guide fit with the secondary hydraulic cylinder 55. Two connecting rods 56 are also provided corresponding to the secondary pistons 57. One end of the connecting rod 56 is fixedly connected to the secondary piston 57, and the other end of the connecting rod 56 passes through the inner wall of the secondary hydraulic cylinder 55 and extends outward. A brake caliper 59 is fixedly connected to the other end of the connecting rod 56. The brake caliper 59 is located in the positioning groove 23. An auxiliary spring 561 is sleeved on the surface of the connecting rod 56. A liquid outlet 512 is provided on the main hydraulic cylinder 51, and a liquid inlet 552 is provided on the secondary hydraulic cylinder 55. The liquid outlet 512 and the liquid inlet 552 are fixedly connected and communicated through a guide pipe 58. The inclined surface of the receiving frame 54 is triggered by the roller 48, and the brake caliper 59 automatically locks into the positioning groove 23 via hydraulic linkage. No additional control components are required, resulting in a compact structure and reliable response, effectively suppressing cutting vibration and improving machining stability.

[0035] In use, when the guide frame 31 reaches the preset position, the second motor 41 drives the threaded rod 42 to rotate around its own axis. The rotation of the threaded rod 42 drives the movable frame 44 to move synchronously along the sliding rod 43 in the direction away from the guide frame 31. The extension frame 45, the third motor 46 and the boring head 47 move synchronously with the movable frame 44. At the same time, the third motor 46 drives the boring head 47 to rotate synchronously around the output shaft of the third motor 46. During this process, the roller 48 on the movable frame 44 first rolls along the triggering inclined surface 541. While the roller 48 rolls along the triggering inclined surface 541, it squeezes the receiving frame 54, causing the receiving frame 54 to move synchronously towards the main hydraulic cylinder 51. The compression spring 521 contracts and increases its elasticity under the compression of the receiving frame 54. The movement of the receiving frame 54 drives the main piston 53 to slide synchronously along the main hydraulic cylinder 51 through the piston rod 52. The main piston 53 squeezes the hydraulic oil. Then, under the action of the hydraulic oil, the two auxiliary pistons 57 move synchronously in opposite directions. The auxiliary spring 561 contracts and increases its elasticity under the compression of the auxiliary pistons 57. The movement of the auxiliary pistons 57 drives the two brake calipers 59 to move synchronously in opposite directions through the connecting rod 56. When the roller 48 leaves the triggering inclined surface 541 and enters the stable plane 542, the position of the receiving frame 54 remains unchanged, and the positions of the two brake calipers 59 remain unchanged. The brake calipers 59 abut against the inner wall of the positioning groove 23 to ensure the stability of the overall structure. During this process, the boring head 47 completes the boring operation on the hole on the pressure vessel cylinder. After the boring operation of the hole is completed, the second motor 41 drives the movable frame 44 to move along the sliding rod 43 towards the guide frame 31. During this process, the roller 48 gradually leaves the stable plane 542 and returns to the triggering inclined plane 541. The elastic force of the compression spring 521 is gradually released and drives the main piston 53 back to the initial position. The elastic force of the auxiliary spring 561 is also gradually released and drives the two auxiliary pistons 57 to move towards each other and return to the initial position. The brake caliper 59 separates from the positioning groove 23.

[0036] In summary, the second motor 41 drives the threaded rod 42 to rotate, and with the guiding effect of the sliding rod 43, the movable frame 44 is stably fed in a straight line, thereby driving the extension frame 45, the third motor 46, and the boring head 47 to accurately reach the machining position. At the same time, the third motor 46 directly drives the boring head 47 to rotate, ensuring the independence and controllability of the cutting action. During this feeding process, the roller 48 rotatably mounted on the movable frame 44 passes through the triggering inclined surface 541 and the stabilizing plane 542 in sequence. The inclined surface pressing action pushes the receiving frame 54 and the piston rod 52 to move, thereby driving the main piston 53 to compress the hydraulic oil in the main hydraulic cylinder 51, pushing the two auxiliary pistons 57 to move synchronously, and driving the brake caliper 59 to tightly contact the inner wall of the positioning groove 23. The contact mechanism locks the boring mechanism 4 and the mounting bracket 2 during the machining process. When the roller 48 enters the stable plane 542, the position of the receiving bracket 54 remains constant, and the brake caliper 59 maintains the locked state, effectively suppressing the vibration and displacement caused by the fluctuation of cutting force during boring, and improving the surface quality and dimensional accuracy of the hole wall. After machining is completed, the brake caliper 59 is released synchronously. The entire positioning and unlocking process does not require additional electrical or pneumatic control components, which simplifies the equipment structure, improves the reliability and automation of positioning response, and ensures the repeatability and consistency of locking and unlocking during multi-hole continuous machining, reducing the time of manual operation and meeting the requirements of high efficiency, stability and intelligence for on-site boring of pressure vessels.

[0037] The working principle of this invention is as follows: Several holes are opened at different positions on the cylinder of the pressure vessel. These holes are used to install various equipment or connect to various pipelines. After the holes are opened, the pressure vessel is placed on the support for subsequent boring operations.

[0038] The linear motion module 1 pulls the mounting frame 2 to move linearly in the horizontal direction. The motion mechanism 3, boring mechanism 4 and positioning mechanism 5 also move synchronously with the mounting frame 2. When the mounting frame 2 reaches the preset position, the first motor 33 drives the rotating shaft 35 to rotate around its own axis through the reducer 34. The rotating shaft 35 rotates and drives the gear 36 to rotate synchronously around the axis of the rotating shaft 35. While rotating, the rotating shaft 35 moves synchronously along the gear ring 22. At the same time, the guide frame 31 slides synchronously along the guide groove 21. The first motor 33 realizes the sliding of the guide frame 31 in two different directions by rotating forward or backward. In addition, the self-locking function of the first motor 33 ensures that the guide frame 31 remains fixed after reaching any position.

[0039] When the guide frame 31 reaches the preset position, the second motor 41 drives the threaded rod 42 to rotate around its own axis. The rotation of the threaded rod 42 drives the movable frame 44 to move synchronously along the sliding rod 43 in the direction away from the guide frame 31. The extension frame 45, the third motor 46 and the boring head 47 move synchronously with the movable frame 44. At the same time, the third motor 46 drives the boring head 47 to rotate synchronously around the output shaft of the third motor 46.

[0040] During this process, the roller 48 on the movable frame 44 first rolls along the triggering inclined surface 541. While the roller 48 rolls along the triggering inclined surface 541, it squeezes the receiving frame 54, causing the receiving frame 54 to move synchronously towards the main hydraulic cylinder 51. The compression spring 521 contracts and increases its elasticity under the compression of the receiving frame 54. The movement of the receiving frame 54 drives the main piston 53 to slide synchronously along the main hydraulic cylinder 51 through the piston rod 52. The main piston 53 squeezes the hydraulic oil. Then, under the action of the hydraulic oil, the two auxiliary pistons 57 move synchronously in opposite directions. The auxiliary spring 561 contracts and increases its elasticity under the compression of the auxiliary pistons 57. The movement of the auxiliary pistons 57 drives the two brake calipers 59 to move synchronously in opposite directions through the connecting rod 56.

[0041] When the roller 48 leaves the triggering inclined surface 541 and enters the stable plane 542, the position of the receiving frame 54 remains unchanged, and the positions of the two brake calipers 59 remain unchanged. The brake calipers 59 abut against the inner wall of the positioning groove 23 to ensure the stability of the overall structure. During this process, the boring head 47 completes the boring operation on the hole on the pressure vessel cylinder.

[0042] After the boring operation of the hole is completed, the second motor 41 drives the movable frame 44 to move along the sliding rod 43 towards the guide frame 31. During this process, the roller 48 gradually leaves the stable plane 542 and returns to the triggering inclined plane 541. The elastic force of the compression spring 521 is gradually released and drives the main piston 53 back to the initial position. The elastic force of the auxiliary spring 561 is also gradually released and drives the two auxiliary pistons 57 to move towards each other and return to the initial position. The brake caliper 59 separates from the positioning groove 23.

[0043] Afterwards, the linear motion module 1 continues to pull the mounting frame 2 to move linearly in the horizontal direction, and the first motor 33 continues to drive the guide frame 31 to slide along the guide groove 21, so that the guide frame 31 reaches the next preset position and performs boring operation on another hole.
