Description

Technical Field

[0001] This utility model belongs to the field of valve body processing technology, specifically relating to a tooling fixture for processing fluid control valve bodies. Background Technology

[0002] Fluid control valves are the core components of fluid control systems. Through their internal channel design and cooperation with movable valve cores (such as slide valves, ball valves, butterfly valves, etc.), they achieve precise adjustment and control of parameters such as pressure, flow rate, and flow direction of liquids or gases. Their structure typically includes inlet / outlet ports, valve core chambers, sealing components, and drive mechanisms (manual, electric, pneumatic, etc.). They are widely used in hydraulics, pneumatics, water treatment, petrochemicals, and other fields, and are key fundamental components ensuring the efficient and stable operation of industrial equipment, construction machinery, and automation systems.

[0003] like Figure 4 As shown, the fluid control valve body is generally cylindrical, with multiple ports on its circumference. During manufacturing, when grinding or threading is required on the inner side of the fluid control valve body, it must first be fixed in place. However, due to the irregular shape of the fluid control valve body, clamping and fixing it is inconvenient. Even with corresponding tooling fixtures, only a single model of fluid control valve body can be fixed, resulting in poor applicability.

[0004] Therefore, there is an urgent need for a fluid control valve body tooling fixture with strong clamping stability and wide applicability. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a tooling fixture for machining fluid control valve bodies, aiming to solve the problems of poor clamping stability and low applicability of existing fluid control valve body fixtures.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] A tooling fixture for machining fluid control valve bodies includes a base plate, on which a vertically arranged hydraulic lifting column and a horizontally arranged electric push rod are provided. A support plate is provided at the upper end of the hydraulic lifting column, and a limiting block with a V-shaped notch is provided on one side of the support plate. A sliding groove is provided on the base plate, and a vertical plate is slidably connected to the sliding groove. The V-shaped notch of the limiting block faces the vertical plate. The electric push rod is used to drive the vertical plate to move horizontally along the sliding groove. A through groove is provided on the vertical plate, and a baffle is slidably connected to the upper part of the through groove. A stop block is slidably connected to both ends of the through groove.

[0008] The vertical plate is equipped with a baffle adjustment mechanism and a stop block adjustment mechanism. The baffle adjustment mechanism is used to adjust the relative position of the baffle and the through groove. One stop block corresponds to one stop block adjustment mechanism, which is used to adjust the relative position of the stop block and the through groove.

[0009] It is also equipped with a controller, and the hydraulic lifting column and electric push rod are both electrically connected to the controller.

[0010] Furthermore, the baffle adjustment mechanism includes a first screw and a movable groove disposed on the surface of the vertical plate and communicating with the through groove. The baffle is disposed in the movable groove. The first screw is threadedly connected to the vertical plate. The lower end of the first screw is rotatably connected to the baffle. The upper end of the first screw passes through the vertical plate and is fixedly connected to a first knob.

[0011] Furthermore, the abutment adjustment mechanism includes a guide groove disposed inside the vertical plate and communicating with the through groove. A second screw is rotatably connected in each guide groove. One abutment corresponds to one abutment adjustment mechanism. The lower part of the abutment extends into the guide groove and is threadedly connected to the corresponding second screw. The end of the second screw away from the vertical plate passes through the vertical plate and is fixedly connected to a second knob.

[0012] This structural design allows for flexible adjustment of the positions of the baffles and blocks according to needs, making it more versatile.

[0013] Furthermore, a pressure sensor is provided on the limiting block.

[0014] This structural design allows for the detection of clamping force by a pressure sensor during the clamping process, ensuring stable clamping while preventing damage to the valve body from excessive force.

[0015] Furthermore, threaded holes are provided at all four corners of the base plate.

[0016] This structural design allows the base plate to be securely fixed with bolts.

The electric push rod 3 is used to drive the vertical plate 6 to move horizontally along the sliding groove. A through groove is provided on the vertical plate 6, and a baffle 7 is slidably connected to the upper part of the through groove. A stop block 8 is slidably connected to both ends of the through groove. The vertical plate 6 is equipped with a baffle adjustment mechanism and a stop block adjustment mechanism. The baffle adjustment mechanism is used to adjust the relative position of the baffle 7 and the through groove; one stop block 8 corresponds to one stop block adjustment mechanism, which is used to adjust the relative position of the stop block 8 and the through groove.

[0027] The tooling fixture of this utility model is also equipped with a controller. The hydraulic lifting column 2, the electric push rod 3, and the pressure sensor are all electrically connected to the controller. The fluid control valve body clamped in this embodiment is as follows: Figure 4 As shown.

[0028] As a preferred embodiment, the baffle adjustment mechanism includes a first screw 9 and a movable groove disposed on the surface of the vertical plate 6 and communicating with the through groove. The baffle 7 is disposed in the movable groove. The first screw 9 is threadedly connected to the vertical plate 6. The lower end of the first screw 9 is rotatably connected to the baffle 7. The upper end of the first screw 9 passes through the vertical plate 6 and is fixedly connected to a first knob.

[0029] As a preferred embodiment, the abutment adjustment mechanism includes a guide groove disposed inside the vertical plate 6 and communicating with the through groove. A second screw 10 is rotatably connected in the guide groove. One abutment 8 corresponds to one abutment adjustment mechanism.

The end of the second screw 10 away from the vertical plate 6 passes through the vertical plate 6 and is fixedly connected to a second knob.

[0030] The specific process of using the tooling fixture of this utility model to clamp the fluid control valve body is as follows:

[0031] First, place the fluid control valve body to be processed on the support plate 4. Then, adjust the height of the support plate 4 so that the interface end of the fluid control valve body is directly aligned with the through groove of the vertical plate 6, and the other end of the fluid control valve body is in close contact with the V-shaped notch of the limiting block 5. Then, according to the size of the fluid control valve body to be processed and the size of its interface end, adjust the relative positions of the baffle 7 and the stop block 8 to match the interface end of the fluid control valve body for easy clamping later.

[0032] Baffle 7 adjustment: By rotating the first screw 9 through the first knob, under the limiting action of the movable groove, the first screw 9 drives the baffle 7 to move up and down along the movable groove until the distance from the bottom plate 1 of the baffle 7 to the lower side of the through groove is equal to the overall height of the fluid control valve body interface end.

[0033] Adjustment of abutment block 8: By rotating the second screw 10 through the second knob, under the limiting action of the guide groove, the second screw 10 drives the abutment block 8 to move left and right along the guide groove until the abutment block 8 abuts against the side of the fluid control valve body interface end, and the distance between the two abutment blocks 8 is equal to the overall width of the fluid control valve body interface end.

[0034] After the baffle 7 and the stop block 8 are adjusted, the electric push rod 3 is started by the controller. The electric push rod 3 drives the vertical plate 6 to move horizontally along the slide groove until the vertical plate 6 is in close contact with the cylindrical surface of the fluid control valve body. At this time, the support plate 4 supports the fluid control valve body, the vertical plate 6 and the limit block 5 with V-shaped notch clamp the cylindrical part of the fluid control valve body, and the vertical plate 6, the baffle 7 and the stop block 8 limit the interface end of the fluid control valve body, thereby realizing the stable clamping and fixing of the fluid control valve body, which is convenient for subsequent processing.
