Description

Technical Field

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

[0002] A valve, also known as a valve or a valve, is a device in a machine that regulates the flow, pressure and flow direction of a fluid, such as a stop valve, a check valve, a pressure reducing valve, a safety valve, etc. A valve includes an actuator, a valve core and a valve body, etc. The valve body is a detachable surface component in the valve, which is used to support the fully closed position of the valve core and form a sealing pair. When producing the valve body, it is necessary to load the valve body and process the inner hole of the valve body. Therefore, valve body milling, drilling and tapping production equipment also plays a very important role.

[0003] The rotary tooling currently on the market usually includes a clamping device and a rotating mechanism. The clamping device is responsible for clamping the valve body, while the rotating mechanism is used to apply rotational motion to the workpiece. The design of the tooling must take into account the shape, size and processing requirements of the valve body. First, the valve body is clamped on the tooling to ensure that it is firmly fixed in the appropriate position. The clamping is usually completed by claws, fixtures or other clamping devices to maintain the stability of the valve body during the processing. After the rotating mechanism is started, the tooling causes the valve body to produce a rotational motion. This rotational motion can be horizontal or vertical, depending on the specific requirements of the processing. This rotation allows the valve body to complete a full range of processing under the action of the tool. The tool is usually fixed on the machine tool instead of moving with the rotation of the valve body, which means that the tool does not need to adjust its position during the processing process and only needs to focus on the cutting or processing operation.

[0004] The rotary tooling used in the valve body machining center currently on the market needs to limit the valve body during use, and then drive the valve body to rotate for machining. However, due to the large turntable, the turntable is prone to shaking during the rotation process, resulting in inaccurate machining of the valve body or even rendering the valve body unusable, reducing the balance and stability of the rotary tooling, making the device unable to meet the needs of users, and the turntable is inconvenient to disassemble, which is not conducive to cleaning and maintenance of the turntable, reducing the convenience of the rotary tooling. Therefore, a rotary tooling for valve body machining with better clamping performance and simpler operation is designed. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a rotary tooling for valve body processing, so as to solve the technical problems of insufficient clamping performance of the rotary tooling and complicated clamping steps.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rotary tool for valve body processing, comprising a main body, a cutting knife is installed on the bottom surface of the top of the main body, a rotating shaft is installed inside the main body, a turntable is installed on the top of the rotating shaft, and a plurality of groups of slide grooves are provided on the top of the turntable, a slider is movably installed inside the slide groove, and a plurality of groups of first clamps are installed on the top of each group of sliders, and each adjacent first clamp is movably aligned with each other.

[0007] By adopting the above technical solution, the first clamp moves inside the slide groove to clamp and fix the valve body, the rotating shaft drives the turntable to rotate, and the cutting knife at the top of the main body cuts the valve body.

[0008] The utility model is further configured such that a limiting groove is provided at the top of the first clamp, and two groups of limiting springs are fixed at the bottom of the limiting groove, a limiting block is installed at the top of the limiting spring, and the limiting block is movably contacted with the inner wall of the limiting groove, a second clamp is installed at the top of the limiting block, and four groups of positioning columns are installed at the bottom of the second clamp, and the positioning columns movably pass through the top of the first clamp.

[0009] By adopting the above technical solution, the positioning column assists the second clamp to perform limiting movement, and the second clamp is pressed down to further fix the valve body. After the cutting of the valve body is completed, the second clamp is reset by the limiting spring.

[0010] The utility model is further configured that limiting shafts are movably installed on both sides of the limiting block, and the top end of the outer wall of the limiting shaft is movably engaged with the limiting inclined block, the limiting inclined block movably passes through the first clamp, a limiting plate is installed at one end of the limiting inclined block, and the outer side of the limiting plate is fitted with the inner wall of the first clamp, and the bottom end of the limiting plate is movably contacted with the first clamp.

[0011] By adopting the above technical solution, during the process of clamping the valve body, the limit plate touches the valve body, and the limit plate is squeezed inward by the valve body. During the inward movement of the limit inclined plate, the inclined surface of the limit inclined plate squeezes the limit shaft downward as it moves, thereby driving the second clamp to move downward, thereby completing further clamping of the valve body.

[0012] In summary, the utility model mainly has the following beneficial effects:

[0013] The utility model clamps and fixes the valve body by the first clamp moving inside the slide groove, the rotating shaft drives the turntable to rotate, and the cutting knife at the top of the main body cuts the valve body. In the process of clamping the valve body, the limit plate touches the valve body, and the limit plate is squeezed and moved inward by the valve body.
