Description

Technical Field

[0001] The present application relates to the technical field of spherical surface grinding, and in particular to a spherical surface grinding device. Background Art

[0002] The core of the ball valve, as an indispensable control component in the pipeline system, is to achieve the flow control, cut-off and even fine adjustment of the fluid medium through the internal rotating ball. The realization of this function is highly dependent on the smoothness and sealing performance of the outer surface of the ball. Therefore, fine grinding and polishing of the ball is not only a key step to improve its appearance texture and aesthetics, but also a necessary measure to ensure the sealing effect of the valve, reduce the flow resistance of the medium, and enhance the overall performance.

[0003] However, in traditional processes, the grinding process of valve balls is quite cumbersome and inefficient. In the specific operation, the valve ball needs to be firmly fixed with a clamp, and then the surface of the ball is carefully polished one by one with sandpaper held manually.

[0004] The above traditional process is not only time-consuming, but also highly dependent on the operator's experience and patience. The slightest mistake may affect the uniformity and accuracy of grinding. After a single valve ball is polished, it needs to be removed from the fixture before the next valve ball can be processed. This cycle will undoubtedly greatly limit production efficiency, especially in the face of large-scale production needs. Its limitations are particularly significant and there is room for improvement. Summary of the invention

[0005] The purpose of this application is to provide a spherical grinding device to solve the problem that the valve ball grinding efficiency of the above-mentioned related technology is low and cannot meet the needs of mass production.

[0007] By adopting the above technical solutions, the spherical grinding equipment has efficient and precise grinding capabilities. The support table is provided with clamping members with adjustable spacing, which can firmly clamp and drive the sphere to rotate. Together with the protective cover and the slidable cabinet door, it ensures the safety and cleanliness during the grinding process. The moving table and the installation table are respectively driven by a driving member and a power member to achieve all-round grinding operations. The grinding head rotates efficiently driven by a driving source to finely grind the surface of the sphere. This design not only greatly improves the grinding efficiency, reduces the tediousness and errors of manual operations, but also ensures the uniformity and precision of grinding through automatic control, meets the requirements of large-scale production, and brings significant benefits to the ball valve manufacturing industry.

[0008] Optionally, the clamping member includes a clamping table installed on the upper side of the support table and a clamping motor fixed on the clamping table. The output shafts of the two clamping motors are arranged facing each other, and a clamping rod is coaxially fixed on the output shaft of the clamping motor; one of the two clamping tables is slidably arranged on the support table, and the other is fixed on the support table; a power source for driving the slidable clamping table to reciprocally slide and adjust in the direction close to the other clamping table is provided on the side of the support table.

[0009] By adopting the above technical solutions, the cooperation between the clamping motor and the clamping rod enables the sphere to be firmly and precisely clamped. At the same time, the output shafts of the clamping motors are arranged facing each other, ensuring the balance of clamping. The slidable design of one clamping table, combined with the power source on the side of the support table, realizes the flexible adjustment of the distance between the two clamping tables, so as to be able to adapt to the clamping requirements of spheres of different sizes. This design not only improves the versatility and adaptability of the equipment, but also makes the clamping and rotation operations of the sphere more convenient and efficient, provides a stable and reliable basis for subsequent grinding treatment, and helps to improve the overall grinding efficiency and quality.

[0010] Optionally, a receiving cavity is opened in the middle of the upper side of the support table. An inlet plate is provided above the base table. A feeding cylinder with a vertically upward hydraulic rod is fixed on the bottom side of the receiving cavity. The end of the hydraulic rod of the feeding cylinder is fixedly connected to the bottom side of the inlet plate. A limiting notch for the sphere to be inserted is opened on the upper side of the inlet plate.

[0011] By adopting the above technical solutions, the cooperation between the receiving cavity opened on the support table, the feeding cylinder and the inlet plate enables the sphere to be accurately placed and lifted to the clamping position. The limiting notch on the inlet plate ensures the stability of the sphere during the lifting process, avoiding the deviation or slipping of the sphere. This design not only simplifies the manual operation, improves the work efficiency, but also reduces the errors caused by human factors, ensures the accuracy and consistency of sphere clamping, and provides a strong guarantee for subsequent grinding treatment.

[0012] Optionally, the two cabinet doors can slide back and forth in a direction parallel to the length direction of the support platform, and the protective cover is blocked when the two cabinet doors slide toward each other to an abutment state. Abutment strips facing the support platform are fixed on the side edges of the two cabinet doors that are close to each other; a locking plate is hinged on the vertical side of the support platform close to the cabinet door, and a locking notch is provided on the locking plate; an adjusting member is provided on the side of the feed plate for driving the locking plate to rotate and adjust, and when the locking plate is rotated to a horizontal state, the two abutment strips in the abutment state can be jointly inserted into the locking notch.

[0013] By adopting the above technical solution, the two cabinet doors can slide along the length of the support platform, and when they slide toward each other to the abutment state, the protective cover can be effectively blocked to prevent the splash of grinding debris and ensure the safety of the working environment. The locking plate hinged on the support platform cooperates with the adjustment piece on the side of the feed plate, so that when the feed plate moves, it can automatically drive the locking plate to rotate to a horizontal state. At this time, the two abutment bars in the abutment state can be inserted into the locking notch together to realize the automatic locking of the cabinet door without the need for additional manual operation, which simplifies the work process, improves work efficiency, and also enhances the safety protection performance of the equipment.

[0014] Optionally, a clearance gap is provided on the side of the support platform close to the cabinet door, and a rotating shaft rotatably connected to the locking plate is provided on the inner wall of the clearance gap, and a torsion spring is sleeved on the outer periphery of the rotating shaft for driving the locking plate to rotate downward; the adjusting member includes an adjusting rod fixedly arranged on the lower edge of the feed plate, and an adjusting plate is vertically fixedly arranged on the side edge of the locking plate close to the rotating shaft; the adjusting plate is located in the accommodating cavity and in a horizontal state when the locking plate is in a vertical state, and the adjusting rod can squeeze the adjusting plate to rotate the locking plate to a horizontal state after the feed plate moves downward.

[0015] By adopting the above technical solution, the adjustment rod on the feed plate interacts with the adjustment plate on the locking plate; the two cabinet doors are slid toward each other in advance to abut each other. When the feed plate moves down (feeding is completed and the ball is ready for grinding), the adjustment rod squeezes the adjustment plate, overcomes the rebound force of the torsion spring, and rotates the locking plate to a horizontal state, realizing automatic locking of the cabinet door, reducing the possibility of unauthorized opening of the cabinet door during grinding. This design not only simplifies the operation process and improves work efficiency, but also ensures that the locking plate can automatically return to a vertical state when not subject to external force through the reset effect of the torsion spring, preparing for the next opening of the cabinet door, further enhancing the safety and reliability of the equipment.

[0016] Optionally, an observation window is installed on the cabinet door, and a scraper for cleaning the inner surface of the observation window is slidably provided on the side of the cabinet door facing the support platform; guide holes are relatively opened on the cabinet door in the vertical direction and are respectively located on both sides of the observation window, and guide rods are fixed at both ends of the scraper, which penetrate the guide holes and extend to the outside, and the guide rods can drive the scraper to slide up and down along the length direction of the guide hole.

[0017] By adopting the above technical solution, the observation window on the cabinet door facilitates the operator to observe the grinding situation in real time, and the setting of the scraping plate effectively solves the problem of blocked line of sight caused by the attachment of grinding debris to the observation window. By sliding the guide rod in the guide through hole, the operator can easily control the up and down movement of the scraping plate to clean the inner side of the observation window and ensure the clarity of observation. This design not only improves work efficiency, reduces operation errors that may be caused by unclear line of sight, but also extends the service life of the observation window and reduces maintenance costs.

[0018] Optionally, a vertically downward positioning rod is fixedly provided on the lower side surface of the scraping plate, a fixing rod is slidably provided horizontally on the inner side surface of the cabinet door, the fixing rod is located on the side of the positioning rod close to the abutting strip, and a fixing groove for the fixing rod to slide and insert is provided on the positioning rod; an elastic pressing member for driving the fixing rod to slide away from the positioning rod is provided on the cabinet door, and a guiding inclined surface is provided on the edge of the end of the fixing rod away from the positioning rod; when the locking plate rotates to the horizontal state, it presses the fixing rod along the guiding inclined surface to insert the fixing rod into the fixing groove.

[0019] By adopting the above technical solution, when the locking plate rotates to the horizontal state, it will press the fixing rod along the guiding inclined surface to insert the fixing rod into the fixing groove of the positioning rod, thereby firmly fixing the scraping plate at the required position and ensuring that the scraping plate will not move due to vibration or other factors during the grinding process; at the same time, the setting of the elastic pressing member enables the fixing rod to automatically rebound when not subjected to external force, facilitating the subsequent adjustment and reset of the scraping plate. In this state, it can drive the scraping plate to move up and down, and then clean the inner side surface of the observation window.

[0020] Optionally, the elastic pressing member includes a guiding block fixedly provided on the inner side surface of the cabinet door, a baffle plate fixedly provided on the outer periphery of the fixing rod, and a first spring. A guiding through hole for the fixing rod to penetrate is provided on the guiding block, the guiding block is located on the side of the baffle plate close to the positioning rod, and both ends of the first spring are fixedly connected to the mutually close side surfaces of the baffle plate and the guiding block.

[0021] By adopting the above technical solution, the cooperation between the guiding block and the guiding through hole provides a stable guiding effect for the sliding of the fixing rod and ensures the accuracy of the movement of the fixing rod. The setting of the baffle plate and the first spring enables the fixing rod to automatically rebound to the initial position under the elastic force of the first spring after being pressed by the locking plate and move, preparing for the next locking operation. This design not only improves the use flexibility of the fixing rod, but also enhances the automation degree of the equipment and reduces the need for manual intervention.

[0022] Optionally, a sealing plate is fixedly provided on the outer periphery of the guide rod, one side of the sealing plate abuts against the outer side surface of the cabinet door, and the sealing plate seals the guide through hole when the guide rod slides up and down to the limit position.

[0023] By adopting the above technical solution, the blocking plate slides up and down along the guide rod, and can block the guide through-hole during its sliding process, preventing debris or dust generated during the grinding process from entering the cabinet through the guide through-hole, thereby protecting the cleanliness inside the cabinet and the normal operation of the equipment.

[0025] By adopting the above technical solution, both ends of the traction rope are fixedly connected to the outer ends of the two guide rods respectively, so that the operator can control the sliding of the two guide rods simultaneously only by holding and moving the traction rope, and then drive the scraper to clean the inner side of the observation window.
