Description

Technical Field

[0001] This utility model belongs to the field of valve processing technology, and in particular relates to a valve flange grinding device. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, and regulating valves, etc. Valves used in fluid control systems have various structures and functions, ranging from the simplest shut-off valves to the various valves used in extremely complex automatic control systems; their types and specifications are quite numerous. The valve body is the main component of the valve, and the other parts of the valve are installed on the valve body to form the valve.

[0003] Flanges need to be machined at the fluid inlet, fluid outlet, and upper end of the valve stem mounting hole on the valve body. The fluid inlet and fluid outlet are used to connect to the pipe body, and the upper end of the valve stem mounting hole is used to install the valve body's upper cover. Currently, existing valve bodies are usually made of casting, forging, or welded steel plates. To ensure the flange's sealing performance and prevent burrs on the flange from scratching workers, the flange usually needs to be ground during valve body machining.

[0004] Currently, traditional grinding devices have a relatively simple structure, and can only adjust the position of the grinding head in the vertical direction. Therefore, they can only be used to grind the outer surface of the workpiece, which limits the grinding range and results in low work efficiency. In addition, when driving the grinding head to move up and down, traditional grinding devices often use a drive motor that drives the grinding head to move up and down synchronously. However, due to the large weight of the drive motor, the stability of the lifting and moving is poor. At the same time, the drive motor is large in size, which requires a lot of space when moving, making it difficult to make reasonable use of space and inconvenient to use. Therefore, there is an urgent need to design a valve flange grinding device to solve the above problems. Utility Model Content

[0005] This invention provides a valve flange grinding device with a reasonable structural design to solve the technical problems existing in the prior art. The grinding wheel in this invention can move in the X, Y, and Z axes, thereby performing grinding operations on the outside and inside of the valve flange, expanding the grinding range and improving work efficiency; at the same time, the grinding wheel does not drive its drive motor to rise or fall when it moves, requiring only a small space to achieve lifting and moving, and has strong movement stability.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A valve flange grinding device includes a frame, on which a clamping assembly for clamping workpieces is mounted; it also includes a support base fixed to the frame, on which a longitudinal sliding mounting base is mounted; it further includes a Y-axis adjustment assembly mounted on the support base for driving the longitudinal sliding mounting base to move along the axial direction; it also includes an X-axis adjustment assembly mounted on the Y-axis adjustment assembly for driving the longitudinal sliding mounting base to move along the X-axis; and it further includes a Z-axis adjustment assembly mounted on the X-axis adjustment assembly for driving the longitudinal sliding mounting base to move along the Z-axis; a longitudinally arranged... The assembly includes a wheel axle with a grinding wheel mounted at its lower end; a rotary drive assembly mounted on a Z-axis adjustment component for driving the wheel axle to rotate; the rotary drive assembly includes a rotary drive sleeve rotatably connected to the Z-axis adjustment component and slidingly engaged with the wheel axle, the wheel axle and the rotary drive sleeve being fixed in the circumferential direction and capable of relative movement in the axial direction; a rotary drive mechanism for driving the rotary drive sleeve to rotate; and a clamping assembly including a clamping mounting base with two sets of clamping blocks mounted on it, a valve support for supporting the workpiece between the two sets of clamping blocks, and a clamping drive mechanism for driving the two sets of clamping blocks to move synchronously towards each other or away from each other.

[0007] The advantages and positive effects of this utility model are as follows: This utility model provides a valve flange grinding device. Through the clamping assembly, the valve flange to be ground can be clamped and positioned. Through the rotary drive assembly, the wheel axle and grinding wheel can rotate, allowing the rotating grinding wheel to grind the workpiece. Through the movable engagement of the rotary drive sleeve with the wheel axle, it is ensured that the grinding wheel's lifting and lowering movement will not cause the rotary drive mechanism driving its rotation to lift or lower. Therefore, only a small space is needed to achieve the lifting and lowering movement of the grinding wheel, resulting in strong movement stability. Through the Y-axis adjustment assembly, X-axis adjustment assembly, and Z-axis adjustment assembly, the grinding wheel can be moved in the X-axis, Y-axis, and Z-axis directions, thereby adjusting the grinding range of the valve flange. This allows the rotating grinding wheel to grind both the exterior and interior of the flange, improving work efficiency.

[0020] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided in detail:

[0021] Please see Figure 1 The valve flange grinding device of this utility model includes a frame 1, with several support legs and several casters installed at the bottom of the frame 1. A clamping assembly 2 for clamping the workpiece is installed on the frame 1.

[0022] See further Figure 4The aforementioned clamping assembly 2 includes a clamping mounting base 2-2 mounted on the frame 1, on which two sets of clamping blocks 2-3 are mounted opposite each other. Each clamping block 2-3 has a V-groove at its inner end that adapts to the outer wall of the flange for clamping the outer wall of the valve flange. A valve support 2-4, mounted on the clamping mounting base 2-2, for supporting the workpiece is provided between the two sets of clamping blocks 2-3. The assembly also includes a clamping drive mechanism 2-1 for driving the two sets of clamping blocks 2-3 to move synchronously towards each other or away from each other.

[0023] like Figure 5 As shown, the clamping drive mechanism 2-1 includes a horizontally arranged clamping guide rail 2-1-8 fixedly connected to the clamping mounting base 2-2. Two sets of clamping sliders 2-1-7 for mounting two sets of clamping blocks 2-3 are slidably connected to the clamping guide rail 2-1-8. Multiple sets of bent drive swing arms 2-1-5 are pivotally connected to the clamping guide rail 2-1-8. All drive swing arms 2-1-5 are L-shaped. -5 The bent end is pivotally connected to the clamping guide rail 2-1-8 via a pin; in addition, the above-mentioned drive swing arms 2-1-5 are provided in four sets, the four sets of drive swing arms 2-1-5 are arranged in pairs, and the two drive swing arms 2-1-5 in each pair are respectively arranged on both sides of the clamping guide rail 2-1-8, and are symmetrically arranged about the clamping guide rail 2-1-8. In addition, the two sets of drive swing arms 2-1-5 located on the same side of the clamping guide rail 2-1-8 are also symmetrically arranged.

[0024] Each drive arm 2-1-5 has a second slot 2-1-6 at its upper end. The drive arm 2-1-5 is movably connected to the corresponding clamping slider 2-1-7 by a screw that slides through the second slot 2-1-6. Each drive arm 2-1-5 has a first slot 2-1-3 at its lower end.

[0025] In actual operation, the flange to be ground is placed on the valve support 2-4, and the clamping drive mechanism 2-1 is activated, which drives the clamping drive block 2-1-2 to descend, thereby pulling the lower end of the drive swing arm 2-1-5. Since the drive swing arm 2-1-5 is pivotally connected to the clamping guide rail 2-1-8, pulling the lower end of the drive swing arm 2-1-5 downward can cause its upper end to flip inward, thereby causing the corresponding two sets of clamping sliders 2-1-7 to move towards each other, thus achieving the purpose of moving the clamping blocks 2-3 installed on them towards each other, thereby achieving the purpose of clamping the flange.

In this embodiment, the grinding wheel 4 is a nylon wheel, and the outer diameter of the grinding wheel 4 is smaller than the inner diameter of the flange, thereby facilitating the grinding wheel 4 to perform grinding and deburring operations on the inside of the flange.

[0040] Working principle:

[0041] Place the flange to be ground on the valve support 2-4, and start the clamping cylinder 2-1-1 in the clamping drive mechanism 2-1. Its piston rod retracts, causing the two sets of clamping blocks 2-3 to move towards each other, thereby clamping the flange. Then, turn on the rotary motor 9-5 in the rotary drive assembly 9 to drive the wheel axle 5 and the grinding wheel 4 to rotate. At the same time, start the Z-axis motor 8-5 in the Z-axis adjustment assembly 8 to drive the grinding wheel 4 to move longitudinally to a position where it can grind the flange held by the clamping assembly 2. During the grinding process, the Y-axis adjustment assembly 6, X-axis adjustment assembly 7 and Z-axis adjustment assembly 8 can drive the grinding wheel 4 to move in the X-axis, Y-axis and Z-axis directions, thereby adjusting the grinding range of the workpiece to be ground. This allows the rotating grinding wheel 4 to perform grinding operations on the outside and inside of the flange, improving work efficiency.
