Description

Technical Field

[0001] The utility model relates to the technical field of valve body production and processing, in particular to a tooling fixture for valve body processing. Background Art

[0002] The valve body is a major component in the valve. There are different mechanical manufacturing methods according to the pressure level, such as casting, forging, etc. It is usually made by casting or forging, and has good corrosion resistance and high temperature performance, as well as high strength and rigidity. The material of the valve body can be cast iron, cast steel, stainless steel, carbon steel, plastic, copper and other materials according to different process media. In the process of valve body production and processing, in order to ensure the accuracy and efficiency of the processing, tooling and fixtures are needed. The valve body maintains a stable position and posture during the processing, thereby improving the processing accuracy and efficiency.

[0003] Common fixtures for valve body processing are usually composed of a main body, a positioning mechanism, a clamping mechanism, an adjustment mechanism, and a connecting mechanism. First, place the valve body at the corresponding position of the main body, and then use the positioning mechanism to determine the exact position of the valve body in the fixture. Finally, fix the valve body through the clamping mechanism, the adjustment mechanism, and the connecting mechanism. This is the common structure and use of fixtures for valve body processing. Traditional fixtures for valve body processing use multiple nuts and screws to cooperate with each other to clamp the valve body. Although its structure is relatively simple, its operation steps are cumbersome and it is not easy to install and disassemble the valve body. For example, patent number CN220145735U is a fixture for processing the valve body of a stop valve. The valve body is placed on a telescopic plate device and pressed down. Then, the circular substrate can be fixed to the valve body by rotating the threaded rod. Otherwise, it can be removed and dismantled. The operation is convenient and the efficiency is improved. However, in this method, since there are many processing methods for the valve body, including cutting and grinding, debris will be generated during the processing, and the debris will splash into the interior of the threaded rod, which will not only cause friction inside the threaded rod, causing wear and even scratches on the thread surface, but will also get stuck between the moving parts of the threaded rod, causing it to get stuck or unable to rotate, resulting in the threaded rod being unable to be used normally. For this reason, a tooling fixture for valve body processing is proposed. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies of the prior art, the utility model provides a tooling fixture for valve body processing to solve the technical problem that the debris splashes into the interior of the threaded rod and cannot be used normally.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a tooling fixture for valve body processing, comprising:

[0008] A workbench, and slideways arranged on the front and back sides of the workbench, and a double-headed motor is installed at the center of the inner cavity of the workbench;

[0009] The rotating gear is arranged at the front and rear ends of the inner cavity center of the workbench and is coaxially connected with the double-head motor, and the top and bottom of the rotating gear are meshed with gear blocks;

[0010] The movable seat is arranged on both sides of the top of the workbench, and the bottom of the movable seat is installed with a slider, and is connected to the corresponding tooth block plate through a slide groove, and a clamp is added on one side of the movable seat. The rotating gear is driven by a double-headed motor to rotate in the inner cavity of the workbench, and the two groups of tooth block plates drive the corresponding movable seat and clamp to move toward each other along the slide groove through the slider, so as to clamp and fix the valve body. On the one hand, since the slide groove is not arranged on the top of the workbench, when the valve body is processed, it is prevented from entering debris, making the movable structure unusable; on the other hand, the movable structure of the device adopts a single set of rotating gears to drive the two groups of tooth block plates to move toward each other, so that the clamp moves toward each other to fix the valve body. Compared with the traditional method of using a threaded rod to drive the clamp to move, the structure is less affected by the vibration generated by the valve body processing.

[0011] Preferably, support legs are longitudinally installed on both sides of the bottom of the workbench, and slide grooves are opened at the upper and lower parts of the front and back of the workbench. The support legs provide stable support for the workbench, and the slider on the moving seat can pass through the corresponding slide groove and be connected to the corresponding gear block plate.

[0012] Preferably, both sides of the center of the surface of the tooth block plate are slidably connected to the limit blocks, and the corresponding parts of the outer surfaces of the limit blocks are connected to the inner wall of the workbench. The tooth block plate can move along the limit blocks, thereby ensuring that the tooth block plate moves horizontally.

[0013] Preferably, hydraulic rods are installed at the front and rear ends of the top center of the moving seat, and an annular box is added just above the top center of the moving seat and connected to the telescopic end of the hydraulic rod. The hydraulic rod can drive the annular box and its connecting structure on the moving seat to perform lifting and lowering adjustment.

[0014] Preferably, a driving motor is installed transversely at the center of the outer side of the annular box, and a rotating ring is rotatably connected to the inner cavity of the annular box and coaxially connected to the corresponding driving motor. The driving motor on the annular box can drive the rotating ring to rotate in the inner cavity of the annular box.

[0015] Preferably, the inner side of the rotating ring is provided with a rotating rod, and the rotating rod extends outward through the annular box and is connected to a connecting plate, and the connecting plate and the clamping plate are connected to each other. The rotating ring drives the connecting plate, the clamping plate and the valve body to rotate in the same direction through the rotating rod. On the one hand, the valve body can be rotated and adjusted to facilitate the subsequent comprehensive processing of the valve body; on the other hand, the valve body can be raised and lowered, which can not only make the clamping plate clamp and fix the corresponding parts of the valve body surface of different sizes within a certain range, but also avoid the collision between the valve body and the workbench when driving the valve bodies of different sizes to rotate.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a tooling fixture for valve body processing, which has the following beneficial effects:

[0018] The tooling fixture for valve body processing uses a double-headed motor to drive the rotating gear to rotate in the inner cavity of the workbench, and the two sets of tooth blocks and plates drive the corresponding moving seats and clamps to move toward each other along the slide groove through the slider, so as to clamp and fix the valve body. With this method, on the one hand, since the slide groove is not arranged on the top of the workbench, when the valve body is processed, it is possible to avoid the entry of debris, which would make the moving structure unusable; on the other hand, the moving structure of the present device uses a single set of rotating gears to drive the two sets of tooth blocks and plates to move toward each other, so that the clamps move toward each other to fix the valve body for processing. Compared with the traditional method of using a threaded rod to drive the fixture to move, the present structure is less affected by the vibration generated by the valve body processing.
