Description

Technical Field

[0001] This utility model relates to the field of valve processing equipment technology, and in particular to a tooling fixture for processing valves. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control the flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the conveyed medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc.

[0003] The utility model with authorization announcement number CN218965227U relates to the field of valve processing technology, and in particular to a valve processing fixture, including a support base, with movable plates on both sides of the support base, and movable grooves on opposite sides of the two movable plates. A one-way lead screw is installed in the movable groove, with an adjusting nut at the top of the one-way lead screw. Threaded blocks are fitted onto both one-way lead screws. An installation block is located on the side of the threaded block closest to the movable groove, and a connecting block is located on the side of the installation block furthest from the movable groove. A replaceable limiting rod is located on one side of the connecting block, and a limiting groove is located at the bottom of the installation block. A limiting block is fitted into the limiting groove. This utility model allows for adjustment of the angle of the replaceable limiting rod. By inserting the limiting block into the limiting groove, the position of the replaceable limiting rod is fixed when the valve is fixed. When the valve's position angle needs to be adjusted, the limiting block is removed, and the valve angle is adjusted by adjusting the height of the two installation blocks. The structure is simple and improves the overall practicality of the device.

[0004] The valve processing fixture mentioned in the aforementioned utility model patent lacks a structure for fixing the valve vertically. Fixing the valve solely with a clamp can easily cause the valve to slide down against the clamp during processing, affecting the valve processing. Utility Model Content

[0005] In order to enable valve processing fixtures to reliably clamp and fix valves, this application provides a tooling fixture for processing valves.

[0006] The technical solution for a tooling fixture used in valve machining provided in this application is as follows:

[0007] A tooling fixture for processing valves includes a base with two mounting seats slidably disposed on it. A first driving assembly is provided on the base to drive the two mounting seats closer together or further apart. A protective shell is connected to each mounting seat. The protective shell is cylindrical and can extend into the valve port. Support plates are provided on the protective shell, arranged along its length. Several support plates are equidistantly distributed along the circumference of the protective shell. A second driving assembly is provided on the protective shell to drive the support plates to synchronously spread outward or converge inward along the radial direction of the protective shell. The support plates can press against the inner wall of the valve port. A limiting plate is provided on the support plate, located at the end of the support plate that does not enter the valve port.

[0008] Preferably, the first drive assembly includes a fixed bearing, a bidirectional threaded rod, a nut seat, a mounting plate, and a drive motor. The base has a mounting groove along its length. The fixed bearing is connected to the mounting groove, with one fixed bearing at each end of the groove. The bidirectional threaded rod connects between the two fixed bearings. The drive motor is mounted on the base, and its output shaft is coaxially connected to the bidirectional threaded rod via a coupling. The nut seat is connected to the bidirectional threaded rod, with one nut seat symmetrically located at each end of the rod. The nut seat is cubic in shape, and its sidewalls slide against the inner wall of the mounting groove. The mounting plate is connected to the nut seat, and is positioned parallel to the base. The mounting base is connected to the mounting plate.

[0009] Preferably, the nut seat is arranged in an inverted "T" shape, and the inner cavity of the mounting groove is adapted to the nut seat.

[0010] Preferably, the second drive assembly includes a push cylinder, a push block, a first hinge seat, a second hinge seat, a first connecting rod, a third hinge seat, a fourth hinge seat, and a second connecting rod. The push cylinder is installed inside the protective housing, and the axis of the piston rod of the push cylinder is collinear with the axis of the protective housing. The push block is connected to the end of the piston rod of the push cylinder. The first hinge seat is connected to the side wall of the push block, and three first hinge seats are arranged along the circumference of the push block. The second hinge seat is connected to the support plate and located at the top of the support plate.

The fourth hinge seat is connected to the support plate and located at the bottom of the support plate. One end of the second connecting rod is connected to the third hinge seat via a pin, and the other end is connected to the fourth hinge seat via a pin.

[0011] Preferably, the support plate is provided with anti-slip texture, which is located on the side wall of the valve port inner wall where the support plate presses against the valve.

[0012] Preferably, the support plate is an arc-shaped plate.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This utility model provides a tooling fixture for processing valves. Through the second driving component, all the support plates are driven to expand outward synchronously, so that the support plates are pressed tightly against the inner wall of the valve port. This fixes the valve and restricts its vertical displacement. In addition, the flange of the valve abuts against the limiting plate, which restricts the horizontal displacement of the valve. Thus, the tooling fixture for processing valves can reliably clamp and fix the valve. Attached Figure Description

[0020] This application discloses a tooling fixture for machining valves. (Refer to...) Figure 1 and Figure 2 The tooling fixture for processing valves includes a base 1, on which two mounting seats 2 are slidably mounted. A first drive assembly 3 is provided on the base 1 to drive the two mounting seats 2 to move closer or further apart. A protective shell 4 is connected to the mounting seats 2. The protective shell 4 is cylindrical and can extend into the valve port. A support plate 5 is provided on the protective shell 4. The support plate 5 is arranged along the length of the protective shell 4. Several support plates 5 are evenly distributed along the circumference of the protective shell 4. A second drive assembly 6 is provided on the protective shell 4 to drive the several support plates 5 to synchronously spread outward or converge inward along the radial direction of the protective shell 4. The support plate 5 can press against the inner wall of the valve port. A limit plate 51 is provided on the support plate 5. The limit plate 51 is located at the end of the support plate 5 that does not enter the valve port.

[0021] The second drive assembly 6 drives all the support plates 5 to expand outward synchronously, so that the support plates 5 press tightly against the inner wall of the valve port, fixing the valve and restricting its vertical displacement. The valve flange and the limiting plate 51 abut against each other, restricting the valve's horizontal displacement. Furthermore, the distance between the two mounting seats 2 can be adjusted by the first drive assembly 3 to adjust the spacing between the two clamping stations, which can accommodate valves of different specifications and improve the practicality of the tooling fixture.

[0022] The first drive assembly 3 includes a fixed bearing 31, a bidirectional threaded rod 32, a nut seat 33, a mounting plate 34, and a drive motor 35. A mounting groove is provided on the base 1 along its length. The fixed bearing 31 is connected to the mounting groove, with one fixed bearing 31 at each end of the groove. The bidirectional threaded rod 32 is connected between the two fixed bearings 31. The drive motor 35 is mounted on the base 1, and its output shaft is coaxially connected to the bidirectional threaded rod 32 via a coupling. The nut seat 33 is connected to the bidirectional threaded rod 32, with one nut seat 33 symmetrically located at each end of the rod. The nut seat 33 is cubic in shape, and its sidewalls slide against the inner wall of the mounting groove. The mounting plate 34 is connected to the nut seat 33 and is positioned parallel to the base 1. A mounting base 2 is connected to the mounting plate 34.

[0023] The nut seat 33 is designed in an inverted "T" shape, and the inner cavity of the mounting groove is adapted to the nut seat 33 to prevent the bidirectional threaded rod 32 from shaking when under force.

[0024] The second drive assembly 6 includes a push cylinder 61, a push block 62, a first hinge seat 63, a second hinge seat 64, a first connecting rod 65, a third hinge seat 66, a fourth hinge seat 67, and a second connecting rod 68. The push cylinder 61 is installed inside the protective shell 4, and the axis of the piston rod of the push cylinder 61 is collinear with the axis of the protective shell 4. The push block 62 is connected to the end of the piston rod of the push cylinder 61. The first hinge seat 63 is connected to the side wall of the push block 62, and three first hinge seats 63 are arranged circumferentially along the push block 62. The second hinge seat 65... 64 is connected to the support plate 5 and located at the top of the support plate 5. One end of the first connecting rod 65 is connected to the first hinge seat 63 by a pin, and the other end is connected to the second hinge seat 64 by a pin. The third hinge seat 66 is connected to the side wall of the protective shell 4. Three third hinge seats 66 are arranged along the circumference of the protective shell 4. The fourth hinge seat 67 is connected to the support plate 5 and located at the bottom of the support plate 5. One end of the second connecting rod 68 is connected to the third hinge seat 66 by a pin, and the other end is connected to the fourth hinge seat 67 by a pin.

[0025] The support plate 5 is provided with anti-slip texture. The anti-slip texture is located on the side wall of the valve port inner wall of the support plate 5 that presses against the valve. The anti-slip texture increases the friction between the valve and the support plate 5, which is beneficial to improving the clamping effect.

[0026] The support plate 5 is an arc-shaped plate to prevent the sharp part of the support plate 5 from contacting the inner wall of the valve orifice, which helps to protect the valve when clamping and fixing.

[0027] The implementation principle of a tooling fixture for processing valves according to an embodiment of this application is as follows: During operation, the valve is placed between two protective shells 4, and then the bidirectional threaded rod 32 is driven to rotate by the drive motor 35. The two nut seats 33 move closer to each other synchronously along the mounting groove, driving the mounting seat 2, protective shell 4 and support plate 5 to move closer to the valve, so that the support plate 5 enters the valve port and the limiting plate 51 abuts against the valve flange. Then, the push cylinder 61 is activated to push the push block 62 forward. The push block 62 drives the three arc-shaped plates to simultaneously press against the inner wall of the valve port through the connecting mechanism of the first connecting rod 65 and the second connecting rod 68, so as to achieve a firm fixation.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
