Description

Technical Field

[0001] This utility model belongs to the technical field of ball valve assembly equipment, and relates to a low-torque ball valve processing equipment. Background Technology

[0002] Ball valves are mainly used to cut off or connect the medium in pipelines, and can also be used for fluid regulation and control. A ball valve consists of a valve body, within which a valve stem and a ball are housed. One end of the valve stem is connected to the ball, and the end of the valve stem furthest from the ball is connected to a handle. By turning the handle, the valve stem rotates, thereby rotating the ball. The valve body has an inlet and an outlet at both ends. Due to the excessive torque caused by the rotational friction of the ball core in injection-molded ball valves, the ball core needs to be repeatedly rotated and lubricated with oil after assembly to achieve lubrication and enable the manufacturing of low-torque ball valves.

[0003] Patent application number CN202323291691.9 discloses a highly automated oil spraying device for ball valves, including a base with an oil spraying assembly connected to the base. The oil spraying assembly includes a frame, a fixing mechanism, and an upper oil sprayer. The frame is connected to the base. The fixing mechanism includes a fixed oil spray seat, a movable oil spray seat, and a downward pressure cylinder. The fixed oil spray seat is connected to the base and is used to place the ball valve. The movable oil spray seat is slidably connected to the frame, and the sliding direction of the movable oil spray seat is vertical. The downward pressure cylinder is connected to the frame and is used to drive the movable oil spray seat to slide. The movable oil spray seat and the fixed oil spray seat are used to fix the ball valve. The upper oil sprayer is connected to the movable oil spray seat and is used to spray oil onto the ball valve core.

[0004] The above-mentioned equipment still has some shortcomings: the ball valve is positioned downwards when placed on the fixed injection seat, but the position of the manual mounting cannot be adjusted because it is fixed to the base. This means that when the ball valve handle is inserted into the groove of the manual mounting used to position the irregular handle, it needs to undergo a certain deformation to be inserted horizontally. During this process, the edge of the groove can easily scratch and damage the surface of the handle, thus affecting the surface quality of the ball valve product. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a low-torque ball valve processing equipment. The technical problem this utility model aims to solve is that existing oiling equipment easily leads to surface quality defects in ball valve products.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A low-torque ball valve processing device includes a worktable, a positioning seat, a lifting seat, and a handle rotating seat. A downwardly extending oil injection cylinder is fixedly connected to the lifting seat. The lifting seat is located above the worktable and can move up and down relative to the worktable. The positioning seat has an upwardly protruding positioning boss for positioning and engaging with the ball valve port. A horizontally arranged rotating shaft is rotatably connected to the handle rotating seat. The end of the rotating shaft has a slot for inserting and positioning a ball valve handle. The handle rotating seat is characterized in that it is slidably connected to the upper side of the worktable in a horizontal direction. When the positioning boss is directly below the oil injection cylinder, the handle rotating seat can drive the rotating shaft to translate along the axial direction of the rotating shaft towards the positioning seat.

[0008] The positioning boss on the positioning seat allows the ball valve port to be fitted onto its outer circumference, providing horizontal positioning for the ball valve and ensuring a stable position of the ball valve relative to the positioning seat. This facilitates a stable and reliable oil injection process. The lifting seat, located above the worktable, can move downwards to cooperate with the positioning seat, clamping and positioning the ball valve. Simultaneously, it allows the oil spray nozzle to face downwards, aligning with the ball's center for lubrication. The rotating shaft on the handle rotating seat rotates the ball valve handle via the inner wall of the slot, ensuring even application of lubricating oil to the ball's center and reducing torque caused by ball friction. The handle on the worktable... The handle rotating seat is horizontally slidably connected to the upper side of the worktable, and at the same time, the handle rotating seat moves horizontally along the setting direction of the rotating shaft. In this way, after the ball valve is placed on the positioning seat and held by the lifting seat, the handle rotating seat can move towards the positioning seat so that the ball valve handle is embedded in the slot in the horizontal direction. When the operator positions the ball valve on the positioning seat by hand or with a robotic arm, he only needs to control the ball valve to be placed downwards on the positioning boss. During this process, the ball valve handle will not interfere with the handle rotating seat, thereby avoiding deformation of the ball valve handle during positioning and causing scratches, which helps to ensure the surface quality of the ball valve product.

[0009] In the aforementioned low-torque ball valve processing equipment, the worktable has a horizontally arranged slide rail, and the positioning seat is slidably connected to the slide rail and can move along the slide rail to directly below the oil injection cylinder. This allows the positioning seat to reciprocate along the slide rail, facilitating the placement of the ball valve on the positioning seat, followed by the positioning seat moving directly below the oil injection cylinder for oiling. This effectively separates the ball valve loading position from the oiling position, preventing the loading process from being constrained by the position of the lifting seat or the oil injection cylinder, and ensuring a safe loading space.

[0010] In the aforementioned low-torque ball valve processing equipment, at least one end of the slide rail extends to the edge of the worktable. This facilitates the movement of the positioning seat along the slide rail to the edge of the worktable, allowing the operator to easily pick up the ball valve workpiece from the outside of the worktable for loading, thus improving operational convenience.

[0011] In the aforementioned low-torque ball valve processing equipment, the positioning seat has a vertical support plate with a U-shaped positioning notch along its upper edge. The rotating shaft is perpendicular to the support plate. This positioning notch on the support plate allows the ball valve handle to extend out and engages with the columnar valve body portion at the handle for positioning, ensuring a stable orientation of the ball valve handle. This allows the handle to accurately engage in the slot when the handle rotating seat moves towards the positioning seat, resulting in a stable and smooth oiling process.

[0012] In the aforementioned low-torque ball valve processing equipment, the upper side of the positioning boss has a relief groove with a spherical inner wall. This allows lubricating oil flowing down from above to partially accumulate in the relief groove. After the ball valve is positioned on the positioning seat, it can be partially immersed in the relief groove to achieve oiling. This eliminates the need for an additional oil spraying mechanism, enabling simultaneous oiling from both above and below, resulting in more uniform oiling.

[0013] In the aforementioned low-torque ball valve processing equipment, several vertically arranged guide columns are fixed on the worktable, and all guide columns penetrate the lifting seat. This allows the lifting seat to be guided and limited by the guide columns during its up-and-down movement, facilitating high-precision movement and ensuring optimal oil injection performance.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] After the ball valve is placed on the positioning seat and held by the lifting seat, the handle rotating seat of this low-torque ball valve processing equipment can be moved horizontally towards the positioning seat so that the ball valve handle is embedded in the slot in the horizontal direction. When the operator positions the ball valve on the positioning seat by hand or with a robotic arm, he only needs to control the ball valve to be placed downwards on the positioning boss. During this process, the ball valve handle will not interfere with the handle rotating seat, thus avoiding the ball valve handle being scratched by the edge of the slot and ensuring the surface quality of the ball valve product.

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1 As shown, the ball valve 8 ball core oiling device includes a worktable 1, a positioning seat 2, a lifting seat 3, and a handle rotating seat 4. A downward-pointing oil spray nozzle 5 is fixedly connected to the lifting seat 3. The structure of the oil spray nozzle 5 can refer to the prior art in the background section. The lifting seat 3 is located above the worktable 1 and can move up and down relative to the worktable 1. The up and down movement of the lifting seat 3 can be achieved by existing cylinder drive or motor screw mechanism drive. The positioning seat 2 has an upward-protruding positioning boss 21. A horizontally arranged rotating shaft 41 is rotatably connected to the handle rotating seat 4. The end of the 1 has a slot 411 for the ball valve 8 handle to be inserted and positioned. The shape and structure of the slot 411 can be referred to the prior art in the background. The handle rotating seat 4 is slidably connected to the upper side of the worktable 1 in the horizontal direction. Specifically, the handle rotating seat 4 can be driven by the existing cylinder below to achieve horizontal reciprocating motion, while the rotation of the rotating shaft 41 can be achieved by the transmission of the existing motor and reduction assembly. When the positioning boss 21 is located directly below the fuel injector 5, the handle rotating seat 4 drives the rotating shaft 41 to translate along the axis of the rotating shaft 41 towards the positioning seat 2. The worktable 1 has two horizontally parallel slide rails 6. The direction of the slide rails 6 is perpendicular to the axis of the rotating shaft 41. The positioning seat 2 is slidably connected to the slide rails 6 and can be translated along the slide rails 6 to directly below the fuel injector 5. The positioning seat 2 can be moved horizontally by the existing screw and nut mechanism to ensure the accuracy of movement. The stroke limit of the positioning seat 2 can be achieved by setting and triggering the existing limit switch or position sensor. Its setting and connection method is the prior art. At least one end of the slide rail 6 extends to the edge of the worktable 1. The positioning seat 2 has a vertical support plate 22, and the upper edge of the support plate 22 has a U-shaped positioning notch 221. The rotating shaft 41 is perpendicular to the support plate 22. The upper side of the positioning boss 21 has a relief groove 211 with a spherical inner wall. Four vertically arranged guide posts 7 are fixed on the worktable 1, and the guide posts 7 all pass through the lifting seat 3.

[0021] like Figure 2 As shown, the positioning boss 21 is positioned and engaged with the port of the ball valve 8, and the handle of the ball valve 8 extends out of the positioning notch 221 and the valve body is adapted to the positioning notch 221.

[0022] Working process: The positioning seat 2 moves outward along the slide rail 6 to the edge of the worktable 1. The operator rotates the handle to the specified angle and places the ball valve 8 on the positioning boss 21 of the positioning seat 2. Then, under the drive of the drive mechanism, the positioning seat 2 drives the ball valve 8 to move horizontally along the slide rail 6 to directly below the oil injection cylinder 5. When the lifting seat 3 moves downward, the oil injection cylinder 5 extends into the ball valve 8 and achieves vertical positioning and clamping of the ball valve 8. Then, the handle rotating seat 4 moves towards the positioning seat 2 so that the handle extending out of the positioning notch 221 can be inserted into the slot 411 at the end of the rotating shaft 41. Then, the oil injection cylinder 5 sprays oil onto the ball center. After spraying oil, the rotating shaft 41 rotates actively and drives the ball center to rotate through the handle, so that the lubricating oil is evenly applied to all parts of the ball center.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
