Description

Technical Field

[0001] This application belongs to the technical field of ball valve processing equipment, and particularly relates to a double-station ball valve sphere grinding equipment. Background Art

[0002] As a key actuating element for controlling the flow of media in industrial pipeline systems, the sealing performance of a ball valve directly determines the reliability of the valve under high-temperature, high-pressure, and corrosive working conditions. In the traditional manufacturing process of ball valves, the fitting accuracy between the sphere and the valve seat depends on the manual grinding process after turning and grinding. This operation mode has significant process defects: First, the operator needs to repeatedly adjust the contact angle between the sphere and the grinding tool to cover the entire spherical surface, resulting in high labor intensity and difficult-to-standardize movement trajectories. Second, the uneven manual force application easily leads to deviations in the microscopic geometry of the spherical surface, causing insufficient sealing surface conformity and thus potential media leakage hazards.

[0003] Although single-station mechanical grinding devices have emerged in the prior art, they still have significant limitations: First, the single-station design leads to low processing efficiency, and the equipment utilization rate is restricted by the auxiliary operation time. Second, the coating of grinding media still requires manual intervention, restricting the realization of continuous production.

[0004] Especially for the grinding of large-diameter ball valves, the existing processing generally has the above problems and needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide a double-station ball valve sphere grinding equipment that can solve the above problems.

[0006] The purpose of this application is to provide a double-station ball valve sphere grinding equipment, including: A frame, on the top of which a processing table and a mounting seat are provided; A fixing device, arranged on the processing table, for fixing the sphere to be ground; A grinding device, arranged on the mounting seat, for grinding the fixed sphere; A spraying device, arranged on both sides of the processing table, for spraying auxiliary media for grinding on the sphere; Among them, two fixing devices, two grinding devices, and two spraying devices are provided.

[0007] Using the above-mentioned double-station ball valve sphere grinding equipment, the present application adopts a double-station design to achieve an alternating operation mode. When one station is grinding, the other station can simultaneously complete sphere clamping or other work, effectively eliminating the waiting idle period of traditional single-station equipment, improving the utilization rate of the equipment, and enhancing the processing efficiency. The spraying devices on both sides cooperate with the grinding work to achieve the automation of grinding and spraying. It can effectively eliminate the manual coating link, avoid the problem of uneven medium distribution caused by manual operation, and ensure the stability of grinding quality. The auxiliary medium here is not simply a lubricating fluid, but a composite medium with functions of lubrication, cooling, grinding agent carrier, and cleaning.

[0008] Meanwhile, a control panel is installed on the processing table. There are multiple control buttons on the control panel. The control panel is connected to the fixing device, the grinding device, and the spraying device and is used to control each device.

[0009] Furthermore, the fixing device includes: A fixing seat, including a first seat body and a second seat body arranged at intervals, with a clamping space formed between the two; A first driving structure, arranged on the second seat body, and a first clamping head in contact with the sphere is arranged on its output shaft; A second driving structure, arranged on the first seat body, and a second clamping head in contact with the sphere is arranged on its output shaft; Wherein, the first driving structure can control the first clamping head to extend and cooperate with the second clamping head to clamp the sphere, and the second driving structure can drive the second clamping head to rotate and drive the sphere to rotate.

[0010] When fixing, the first driving structure drives the first clamping head to extend, cooperates with the second clamping head to clamp the sphere. The second clamping head cannot extend and retract, but can only rotate. A force application structure is formed by the first clamping head and the second clamping head to apply an equal pressure to the surface of the sphere. The first driving structure here can be a cylinder, an electric cylinder, or an oil cylinder, which is connected to a power source. Meanwhile, the second driving structure is a motor, which can drive the second clamping head to rotate. The second clamping head directly drives the sphere to rotate around the axis under the clamping state, so as to rotate while ensuring clamping, and then can grind while rotating, and spray the auxiliary medium synchronously during grinding to ensure that the surface of the sphere can be comprehensively ground.

[0011] Furthermore: The grinding device includes: A positioning rod, arranged on the fixing seat, and an installation arm is slidably arranged on the positioning rod; A grinding structure, arranged on the installation arm, for grinding the sphere; An adjusting structure, arranged on the installation arm, for adjusting the position of the grinding structure in the horizontal direction; Among them, a first driver for driving the mounting arm to move up and down is provided at the top of the positioning rod.

[0012] In this application, the mounting base is located at the edge of the processing table, the positioning base is located below the mounting base, and the positioning rod is installed above the mounting base and fixed by bolts, playing a supporting and isolating role. The first driver can be a device with a vertical driving effect, such as a cylinder, an oil cylinder, etc., installed at the top of the positioning rod, and the output shaft is connected to the mounting arm, and can drive the mounting arm to move up and down under the control of the control panel.

[0013] The sliding fit between the positioning rod and the mounting arm forms a vertical guiding reference. With the lifting control of the first driver, it ensures that the grinding structure always maintains a preset trajectory in the Z-axis direction, thus avoiding the problem of grinding pressure fluctuation caused by gravity sag in traditional equipment, especially suitable for the curved surface grinding of large-diameter ball valve spheres. At the same time, the grinding structure can adjust its position in the horizontal direction through the adjustment structure and can adapt to spheres of different diameters.

[0014] Furthermore, the grinding structure includes: A second driver, movably installed above the mounting arm; A rotating rod, arranged on the output shaft of the second driver, and the rotating rod passes through the mounting arm and extends downward; A connecting head, arranged at the bottom of the rotating rod; A universal joint, arranged at the bottom of the connecting head; A grinding head, arranged at the bottom of the universal joint and connected to the sphere; Among them, the second driver drives the connecting head to rotate through the rotating rod, and the connecting head drives the grinding head to rotate through the universal joint to grind the sphere.

[0015] In this application, the second driver is a motor. A slide rail is fixedly connected to the mounting arm, and the second driver is slidably installed on the slide rail. The second driver drives the connecting head to rotate through the rotating rod, and the connecting head drives the grinding head to rotate through the universal joint. The grinding head always maintains contact with the ball head and grinds the sphere by rotating.

[0016] The universal joint can swing freely in three-dimensional space. Through the installation of the universal joint, the grinding head can always maintain contact with the spherical surface of the sphere, and can also automatically compensate for the axial offset during the rotation of the sphere, eliminating the grinding pressure fluctuation caused by the change of the spherical curvature. At the same time, the combined movement of the connecting head and the universal joint makes the grinding head generate a planetary motion trajectory. Compared with single-rotation grinding, this mode can improve the grinding accuracy and grinding range and improve the grinding efficiency of the sphere.

[0017] Further, the connector includes a support plate, a first connecting plate and a second connecting plate located at both ends of the support plate. The first connecting plate is connected to the rotating rod, the second connecting plate is connected to the universal joint, and the length of the second connecting plate is longer than that of the first connecting plate.

[0018] The lengthened design of the second connecting plate can form a lever amplification effect, converting the rotational displacement of the rotating rod into the extended swing amplitude of the grinding head, expanding the contact area of the grinding medium from point contact to surface contact, and eliminating the grinding blind area generated by the traditional symmetric structure. At the same time, as a rigid bearing matrix, the support plate can effectively inhibit the torsional deformation of the connector when bearing the grinding reaction force, ensuring the structural stability. In addition, the lengthened second connecting plate can expand the swing range of the grinding head, enabling the same grinding structure to adapt to the spherical surfaces with different curvature radii, further improving the grinding efficiency.

[0019] Further, the adjustment structure includes: An adjustment space is arranged inside the mounting arm, and a screw rod is arranged inside the adjustment space; A slider is slidably arranged in the adjustment space and is threadedly connected to the screw rod, and the rotating rod passes through the slider; An adjustment handwheel is arranged outside the mounting arm and is connected to the screw rod; Wherein, adjustment grooves communicating with the adjustment space are also formed at the top and bottom of the mounting arm for the rotating rod to move.

[0020] The threaded engagement between the screw rod and the slider forms a self-locking linear guiding mechanism, and the slider can generate a linear displacement along the inside of the adjustment space under the drive of the adjustment handwheel. After the adjustment is completed, the position is automatically locked by the thread to avoid displacement caused by vibration interference during the grinding operation. The opening of the adjustment groove can not only allow the rotating rod to pass through and move, but also limit the moving range of the rotating rod, restricting its moving distance within the adjustment groove. In addition, the adjustment handwheel is installed at one end of the outer wall of the mounting arm close to the control panel, enabling the staff to adjust the grinding position at any time, only by rotating the adjustment handwheel.

[0021] Further, the spraying device includes: A spraying seat, inside which a flow control mechanism is arranged; A robotic arm is installed above the spraying seat, and a spray pipe is installed at the front end of the robotic arm. The spray pipe is connected to the flow control mechanism through a pipeline; Wherein, the flow control mechanism includes a hydraulic pump. The hydraulic pump is connected to a throttle valve through a pipeline. The throttle valve is provided with an inlet and an outlet. The outlet pipeline of the throttle valve is connected to a pump, and the pump is connected to the spray pipe through a pipeline.

[0022] During spraying, the robotic arm can adjust the spraying angle and position of the spray nozzle so that the replication medium can always be sprayed on the sphere. It can also adapt to spheres of different sizes. The robotic arm is a commonly used robotic arm in existing processing, and its specific structure will not be elaborated here. At the same time, through the combined design of a hydraulic pump and a throttle valve, precise control of the spraying medium flow rate can be achieved, avoiding overspraying or insufficient flow, and improving spraying uniformity. Moreover, the structure where the outlet of the throttle valve is connected to the pump forms a dual-pressure guarantee mechanism. The initial pressure can be adjusted through the throttle valve, and the stability of the end output can be maintained through the pump, reducing pressure fluctuations during the spraying process. The flow control mechanism is built into the spraying seat, reducing external pipeline interference and optimizing the utilization rate of the working space.

[0023] By installing a flow control mechanism, through the synergistic effect of hydraulic drive and throttle regulation, waste of the spraying medium can be reduced, and the conveying efficiency can be improved by cooperating with the boosting function of the pump, achieving energy conservation and consumption reduction.

[0024] Furthermore, a falling port is also provided on the processing table. The falling port is located below the clamping space and is used to collect the auxiliary medium.

[0025] The inner wall of the falling port is inclined. The falling hopper fits with the falling port, facilitating the sliding of the auxiliary medium. A falling hopper is also installed on the falling port. Handles are installed on both sides of the falling hopper, facilitating the staff to take out the falling hopper. A collection box is also installed inside the processing table, and the replication medium falling from the falling port is collected in the collection box.

[0026] The beneficial effects of this application are as follows: 1. This application adopts a dual-station design to achieve an alternating operation mode. When one station is grinding, the other station can synchronously complete sphere clamping or other work, effectively eliminating the waiting idle period of traditional single-station equipment, improving the utilization rate of the equipment, and enhancing the processing efficiency; 2. The spraying devices on both sides cooperate with the grinding work, realizing the automation of grinding and spraying, effectively eliminating the manual coating link, avoiding the problem of uneven distribution of the medium caused by manual operation, and ensuring the stability of the grinding quality; 3. The lengthened design of the second connecting plate can form a lever amplification effect, converting the rotational displacement of the rotating rod into the extended swing amplitude of the grinding head, expanding the contact area of the grinding medium from point contact to surface contact, and eliminating the grinding blind area generated by the traditional symmetric structure.

[0043] The sliding fit between the positioning rod 310 and the mounting arm 311 forms a vertical guiding reference. With the lifting control of the first driver 312, it is ensured that the grinding structure 320 always maintains a preset trajectory in the Z-axis direction, thus avoiding the problem of grinding pressure fluctuation caused by gravity sag of traditional equipment, especially suitable for the curved surface grinding of large-diameter ball valve spheres. At the same time, the grinding structure 320 can be adjusted in the horizontal direction through the adjusting structure 340 and can adapt to spheres of different diameters.

[0044] Embodiment 4: The embodiment of the present application provides a double-station ball valve sphere grinding device. In addition to including the above technical features, the double-station ball valve sphere grinding device of the embodiment of the present application further includes the following technical features.

[0045] As Figures 1 to 3 shown, the grinding structure 320 includes: A second driver 321, movably installed above the mounting arm 311; A rotating rod 322, arranged on the output shaft of the second driver 321, and the rotating rod 322 passes through the mounting arm 311 and extends downward; A connecting head 330, arranged at the bottom of the rotating rod 322; A universal joint 324, arranged at the bottom of the connecting head 330; A grinding head 325, arranged at the bottom of the universal joint 324 and connected to the sphere; Wherein, the second driver 321 drives the connecting head 330 to rotate through the rotating rod 322, and the connecting head 330 drives the grinding head 325 to rotate through the universal joint 324 to grind the sphere.

[0046] In the embodiment of the present application, the second driver 321 is a motor. A slide rail is fixedly connected to the mounting arm 311, and the second driver 321 is slidably installed on the slide rail. The second driver 321 drives the connecting head 330 to rotate through the rotating rod 322, and the connecting head 330 drives the grinding head 325 to rotate through the universal joint 324. The grinding head 325 always keeps in contact with the ball head and grinds the sphere by rotation.

[0047] The universal joint 324 can swing freely in three-dimensional space. Through the installation of the universal joint 324, the grinding head 325 can always be in contact with the spherical surface, and it can also automatically compensate for the axial offset during the rotation of the sphere, eliminating the grinding pressure fluctuation caused by the change of the spherical curvature. At the same time, the combined movement of the connecting head 330 and the universal joint 324 makes the grinding head 325 generate a planetary motion trajectory.

At the same time, the support plate 331, as a rigid bearing matrix, effectively inhibits the torsional deformation of the connecting head 330 when bearing the grinding reaction force, ensuring the structural stability. In addition, the lengthened second connecting plate 333 can expand the swing range of the grinding head 325, enabling the same grinding structure 320 to adapt to spherical surfaces with different curvature radii, further improving the grinding efficiency.

The slider 343 can generate a linear displacement along the inside of the adjustment space 341 under the drive of the adjustment handwheel 344. After the adjustment is completed, the thread automatically locks the position to avoid displacement caused by vibration interference during the grinding operation. The opening of the adjustment groove 345 can not only allow the rotating rod 322 to pass through and move, but also limit the moving range of the rotating rod 322, so that its moving distance is limited within the adjustment groove 345.

At the same time, through the combined design of the hydraulic pump 423421 and the throttle valve 422, precise control of the flow rate of the spraying medium can be achieved, avoiding overspray or insufficient flow rate, and improving the spraying uniformity. And the structure of connecting the pump 423 to the outlet of the throttle valve 422 forms a dual pressure guarantee mechanism. The initial pressure can be adjusted through the throttle valve 422, and the stability of the end output can be maintained through the pump 423, reducing the pressure fluctuation during the spraying process. Moreover, the flow control mechanism 420 is built into the spraying seat 410, reducing external pipeline interference and optimizing the utilization rate of the operation space.

[0056] By installing the flow control mechanism 420, it is possible to reduce the waste of spraying medium through the synergistic effect of hydraulic drive and throttling regulation, cooperate with the boosting function of the pump 423 to improve the conveying efficiency, and achieve energy conservation and consumption reduction.
