Abstract
Description
Technical Field
[0001] This utility model belongs to the field of valve plate grinding and processing, and in particular relates to a valve plate grinding machine. Background Technology
[0002] The choke manifold is a crucial piece of equipment connecting the well control unit and the remote control console, used to establish drilling fluid circulation. It is an important means of preventing water jetting during drilling operations. Therefore, the reliability of the choke and kill manifold valve plate is a vital component in preventing well control accidents and ensuring well control safety.
[0003] Currently, valve plates for choke manifolds and kill manifolds in China can only be ground manually. However, manual grinding suffers from uneven force application due to individual differences in technique, resulting in significant variations in friction values of valve plates of the same size and under the same pressure, leading to low reliability of valve plate performance.
[0004] Therefore, it is necessary to design and develop a valve plate grinding machine to achieve automated grinding of the throttle valve plate and avoid the problem of low reliability of valve plate performance caused by manual grinding. Utility Model Content
[0005] The purpose of this invention is to provide a valve plate grinding machine that can automate the grinding of throttle valve plates, improve the reliability of valve plate performance, and ensure that the friction value of the valve plate meets the requirements under the same size and pressure.
[0006] The valve plate grinding machine includes a cabinet. A second sliding mechanism is fixed side by side on the left and right sides of the top of the cabinet. A first sliding mechanism that can move back and forth along the second sliding mechanism is mounted on the second sliding mechanism on the left and right sides. A lifting mechanism that can move left and right along the first sliding mechanism is mounted on the first sliding mechanism. A mounting plate is fixed at the lifting end of the lifting mechanism. A grinding fixture is mounted on the mounting plate. The grinding fixture is used to clamp and fix the valve plate workpiece to be ground and drive the valve plate workpiece to move back and forth. A grinding plate is provided on the cabinet below the first sliding mechanism.
[0007] By coordinating the first sliding mechanism, the second sliding mechanism, and the lifting mechanism, the position of the grinding fixture is changed, thereby driving the valve plate workpiece to reciprocate and rub against the grinding plate. This not only achieves automated grinding of the valve plate workpiece, avoiding the problem of low reliability of valve plate workpiece performance caused by manual grinding, but also improves the reliability of valve plate performance. This ensures that the friction value of the valve plate meets the requirements under the same size and pressure. Furthermore, it enables the position adjustment of the valve plate workpiece in three axes and six directions, allowing the machine to grind and process valve plate workpieces of different sizes and specifications, greatly improving the adaptability of the machine.
[0008] Furthermore, a second drive motor for driving the first sliding mechanism to move back and forth is fixed at the rear end of the second sliding mechanism, and a first drive motor for driving the lifting mechanism to move left and right is fixed at the right end of the first sliding mechanism.
[0009] The first sliding mechanism is driven to move back and forth by the second drive motor, and the lifting mechanism is driven to move left and right by the first drive motor. This not only enables the position adjustment of the grinding fixture, but also ensures the quality of the valve plate grinding process and improves the reliability of the valve plate performance by controlling the high precision of the motor.
[0010] Furthermore, a first cable chain is connected between the lower part of the first drive motor and the top of the cabinet, and a second cable chain is connected between the rear side of the lifting mechanism and the top of the first sliding mechanism.
[0011] By setting up the first and second drag chains, the movement process of the first sliding mechanism and the lifting mechanism can be made more stable, thereby further ensuring the quality of the valve plate grinding process and improving the reliability of the valve plate performance.
[0012] Furthermore, the grinding fixture includes a clamping cylinder, clamping blocks, and clamping seats. Both ends of the piston rod of the clamping cylinder are fixed with clamping blocks. The clamping cylinder can drive the two clamping blocks to move towards each other or away from each other. A clamping seat is clamped between the clamping blocks on both sides. The valve plate workpiece is placed in the clamping seat. The clamping seat is made of soft material.
[0013] By using a clamping seat made of soft material, rigid contact between the clamping block and the valve plate workpiece can be avoided, thus preventing damage to the surface of the valve plate workpiece. At the same time, the clamping cylinder drives the valve plate workpiece to reciprocate, thereby utilizing the friction between the valve plate workpiece and the grinding plate to achieve the grinding process of the valve plate workpiece. Compared with the traditional manual masking method, the force is more uniform, and the friction value of the valve plate of the same size and under the same pressure after processing is smaller, which improves the performance reliability of the valve plate.
[0014] Furthermore, a U-shaped groove is provided at the lower part of the clamping seat, and the depth of the U-shaped groove is less than the thickness of the valve plate workpiece.
[0015] By setting the U-shaped groove, the upper part of the valve plate workpiece can be embedded in the U-shaped groove, thereby increasing the contact area between the valve plate workpiece and the clamping seat, increasing the clamping force of the grinding fixture on the valve plate workpiece, avoiding the phenomenon of unsatisfactory grinding effect due to poor clamping of the valve plate workpiece, and helping to ensure the quality of grinding processing.
[0016] Furthermore, a control panel is formed on the upper part of the cabinet, and a display module and a power switch are arranged on the control panel from left to right. An operation knob is arranged on the control panel below the power switch.
[0017] The display module is used to set and display the parameters of the grinding process, the power switch is used to control the power supply to the cabinet, and the operation knob is used to control and adjust the grinding process. By setting the display module, power switch, and operation knob, the automation level of the machine can be improved, and the automated grinding of valve plate workpieces can be better realized.
[0018] Furthermore, multiple support components are provided at the bottom of the cabinet.
[0019] The installation of multiple support components can improve the stability of the cabinet during the grinding process, which helps to ensure the grinding quality of the valve plate workpiece.
[0020] Furthermore, the support assembly includes a support leg, a fixing plate, and fixing bolts. The upper end of the support leg is fixedly connected to the bottom of the cabinet, and the lower end of the support leg is fixedly connected to the center of the fixing plate. Multiple fixing bolts are installed on the fixing plate around the support leg.
[0021] The support components described above enable a stable and reliable connection between the cabinet and the ground, which helps to ensure the grinding quality of the valve plate workpiece.
[0022] Furthermore, the grinding plate is fixed to the top of the cabinet by multiple fixing fixtures.
[0023] Fixtures can improve the fixation of the grinding plate, preventing it from shifting during the grinding process and affecting the grinding effect.
[0024] Furthermore, the cabinet includes a cabinet body, hinges, and a cabinet door. The left and right sides of the cabinet body are respectively rotatably connected by several hinges and the outer side of a cabinet door. The inner side of the cabinet door is connected to the cabinet body by a locking mechanism.
[0025] The cabinet structure described above allows for easy installation of control modules and power supplies, and facilitates maintenance of the cabinet's internal structure by opening the cabinet door.
[0026] Compared with the prior art, the present invention has the following beneficial effects:
[0027] This utility model, through the cooperation of the first sliding mechanism, the second sliding mechanism, the clamping fixture (10) and the lifting mechanism, can not only drive the valve plate workpiece to move back and forth to realize the automated grinding of the throttle valve plate workpiece, avoiding the problem of low reliability of valve plate workpiece performance caused by manual grinding, but also improve the reliability of valve plate performance, thereby ensuring that the friction value of the switch valve plate under the same size and pressure meets the requirements. Moreover, it realizes the position adjustment of the valve plate workpiece in three axes and six directions, so that the machine can grind and process valve plate workpieces of different sizes and specifications, greatly improving the adaptability of the machine.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
[0033] See appendix Figure 1 -Appendix Figure 3 A valve plate grinding machine includes a cabinet 1. A second sliding mechanism 16 is fixed side by side on the left and right sides of the top of the cabinet 1. A first sliding mechanism 8 is straddling the second sliding mechanism 16 on the left and right sides, and a lifting mechanism 11 is installed on the first sliding mechanism 8, which can move back and forth along the second sliding mechanism 16. A mounting plate 12 is fixed at the lifting end of the lifting mechanism 11. A grinding fixture 10 is installed on the mounting plate 12. The grinding fixture 10 is used to clamp and fix the valve plate workpiece 9 to be ground and drive the valve plate workpiece 9 to reciprocate. A grinding plate 7 is provided on the cabinet 1 below the first sliding mechanism 8. The grinding plate 7 is fixed to the top of the cabinet 1 by multiple fixing fixtures 6.
[0034] This embodiment uses the cooperation of the first sliding mechanism 8, the second sliding mechanism 16, and the lifting mechanism 11 to change the position of the grinding fixture 10. The grinding fixture 10 drives the valve plate workpiece 9 to slide back and forth, realizing the frictional movement between the valve plate workpiece 9 and the grinding plate 7. This not only realizes the automated grinding of the valve plate workpiece 9, avoiding the problem of low reliability of the valve plate workpiece 9 caused by manual grinding, but also improves the reliability of the valve plate performance. This ensures that the friction value of the switch valve plate meets the requirements under the same size and pressure. Furthermore, it realizes the position adjustment of the valve plate workpiece 9 in three axes and six directions, so that the machine can grind and process valve plate workpieces 9 of different sizes and specifications, greatly improving the adaptability of the machine.
[0035] In this example, the mounting plate 12 is L-shaped, with its vertical portion connected to the lifting end of the lifting mechanism 11, and the grinding fixture 10 fixedly mounted on the lower surface of its horizontal portion.
[0036] from Figure 1 It can also be seen that a control panel 2 is formed on the upper part of the cabinet 1. A display module 3 and a power switch 4 are arranged on the control panel 2 from left to right. An operation knob 5 is located on the control panel 2 below the power switch 4. The display module 3 is used to set and display the parameters of the grinding process, the power switch 4 is used to control the power supply to the cabinet 1, and the operation knob 5 is used to control and adjust the grinding process. Thus, the arrangement of the display module 3, power switch 4, and operation knob 5 improves the automation level of the machine and better realizes the automated grinding of the valve plate workpiece 9. Furthermore, multiple support components 15 are arranged at the bottom of the cabinet 1. The arrangement of multiple support components 15 improves the stability of the cabinet 1 during the grinding process, helping to ensure the grinding quality of the valve plate workpiece 9. Ventilation windows 19 are also provided on the left and right side walls of the cabinet 1 for heat dissipation of the equipment inside the cabinet 1.
[0037] In this example, in order to drive the first sliding mechanism 8 to move back and forth and drive the lifting mechanism 11 to move left and right, a second drive motor 18 for driving the first sliding mechanism 8 to move back and forth is fixed at the rear end of the second sliding mechanism 16, and a first drive motor 13 for driving the lifting mechanism 11 to move left and right is fixed at the right end of the first sliding mechanism 8.
[0038] Meanwhile, in order to make the movement of the first sliding mechanism 8 and the lifting mechanism 11 more stable, thereby further ensuring the quality of the valve plate grinding process and improving the reliability of the valve plate performance, a first drag chain 14 is connected between the lower part of the first drive motor 13 and the top of the cabinet 1, and a second drag chain 17 is connected between the rear side of the lifting mechanism 11 and the top of the first sliding mechanism 8.
[0039] In this example, the first sliding mechanism 8 and the second sliding mechanism 16 both adopt linear slide modules, and the lifting mechanism 11 adopts a lifting cylinder or a linear slide module.
[0040] from Figure 1 As can be seen from the diagram, the cabinet 1 includes a cabinet body 101, hinges 102, and a cabinet door 103. The left and right sides of the cabinet body 101 are respectively rotatably connected by several hinges 102 and the outer side of a cabinet door 103. The inner side of the cabinet door 103 is connected to the cabinet body 101 by a locking mechanism.
[0041] With the structure of the cabinet 1 described above, control modules and power supplies can be easily installed inside the cabinet 1, and the structure inside the cabinet 1 can be easily maintained by opening the cabinet door 103.
[0042] from Figure 1 It can also be seen that the support assembly 15 includes a support leg 1501, a fixing plate 1502, and fixing bolts 1503. The upper end of the support leg 1501 is fixedly connected to the bottom of the cabinet 1, and the lower end of the support leg 1501 is fixedly connected to the center of the fixing plate 1502. Multiple fixing bolts 1503 are provided on the fixing plate 1502 around the support leg 1501.
[0043] The support component 15 of the above structure enables a stable and reliable connection between the cabinet 1 and the ground, which helps to ensure the grinding quality of the valve plate workpiece 9.
[0044] See appendix Figure 3 The grinding fixture 10 includes a clamping cylinder 1001, a clamping block 1002, and a clamping seat 1003. The piston rod of the clamping cylinder 1001 is fixed with clamping blocks 1002 at both ends. The clamping cylinder 1001 can drive the two clamping blocks 1002 to move towards each other or away from each other. The clamping seat 1003 is clamped between the clamping blocks 1002 on both sides. The valve plate workpiece 9 is placed in the clamping seat 1003. The clamping seat 1003 is made of soft material.
[0045] In this embodiment, the clamping seat 1003, made of soft material, avoids rigid contact between the clamping block 1002 and the valve plate workpiece 9, thus preventing damage to the surface of the valve plate workpiece 9. At the same time, the clamping cylinder 1001 drives the valve plate workpiece 9 to reciprocate, thereby utilizing the friction between the valve plate workpiece 9 and the grinding plate 7 to achieve the grinding process of the valve plate workpiece 9. Compared with the traditional manual masking method, the force is more uniform, and the friction value of the valve plate of the same size and under the same pressure after processing is smaller, which improves the performance reliability of the valve plate.
[0046] Preferably, the lower part of the clamping seat 1003 is provided with a U-shaped groove, and the depth of the U-shaped groove is less than the thickness of the valve plate workpiece 9. By providing the U-shaped groove, the upper part of the valve plate workpiece 9 can be embedded in the U-shaped groove, thereby increasing the contact area between the valve plate workpiece 9 and the clamping seat 1003, increasing the clamping and fastening force of the grinding fixture 10 on the valve plate workpiece 9, and avoiding the phenomenon of unsatisfactory grinding effect due to poor clamping of the valve plate workpiece 9, thus helping to ensure the quality of the grinding process.
[0047] Based on the above structural description, the working principle of the valve plate grinding machine described in this embodiment is as follows:
[0048] First, turn on the machine using power switch 4, and then set the grinding parameters using control panel 2;
[0049] Then, the clamping cylinder 1001 is controlled to drive the clamping blocks 1002 on both sides to move, so as to fix the valve plate workpiece 9 between the clamping blocks 1002 on both sides through the clamping seat 1003.
[0050] Then, control the first drive motor 13 and the second drive motor 18 to drive the lifting mechanism 11 to move within the range of the grinding plate 7;
[0051] Next, abrasive sand is placed on the grinding plate 7, and the lifting mechanism 11 is controlled to drive the valve plate workpiece 9 to sink until it contacts the grinding plate 7.
[0052] Finally, the first drive motor 13 and the second drive motor 18 are controlled to drive the lifting mechanism 11 and the grinding fixture 10 to move, so that the valve plate workpiece 9 moves back and forth on the grinding plate 7, thereby using the grinding plate 7 and the grinding sand on it to grind the valve plate workpiece 9 to the process requirements.
[0053] In summary, this machine achieves automated grinding of valve plate workpiece 9. Compared with the traditional manual masking method, the force is more uniform, and the friction value of the valve plate of the same size and under the same pressure after processing is smaller, which improves the performance reliability of the valve plate and ensures that the friction value of the valve plate of the same size and under the same pressure meets the requirements. Moreover, it realizes the position adjustment of valve plate workpiece 9 in three axes and six directions, which enables the machine to grind and process valve plate workpieces 9 of different sizes and specifications, greatly improving the adaptability of the machine.
