Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, and more specifically, to a machining positioning tooling for a four-way valve body. Background Technology

[0002] like Figure 1 The four-way valve body shown needs to be ground and leveled after casting. Traditionally, the processing of the two ends of the four-way valve body relies on manual operation. One end of the four-way valve body is first locked to the workbench with bolts, and the other end is ground. Then it is turned upside down and fixed to grind the other end. This operation is inconvenient and results in low processing efficiency. Utility Model Content

[0003] This utility model provides a machining and positioning fixture for a four-way valve body, which aims to improve the technical problem of low machining efficiency caused by inconvenient operation when manually machining a four-way valve body.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a machining and positioning fixture for a four-way valve body, comprising a base plate, a positioning post and a limiting block provided on the base plate, a detachable mounting cap on the positioning post, and the limiting block provided on one side edge of the base plate.

[0005] Furthermore, the pressure cap includes a disc and a pressure plate, the disc being mounted on the bottom of the pressure plate, and the pressure plate having several pressure blocks protruding circumferentially.

[0006] Furthermore, two positioning rods are provided at the upper end of the positioning post, and two positioning holes are provided on the pressure cap.

[0007] Furthermore, the limiting block includes two blocks, which are symmetrically arranged, and the limiting blocks are equipped with adjustable bolts.

[0008] Furthermore, a frustum is provided on the bottom of the positioning post on the base plate, and the frustum is locked to the base plate by bolts.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This utility model discloses a simple and ingeniously designed machining and positioning fixture for a four-way valve body. It includes a base plate with a positioning post and a limiting block. A detachable mounting cap is attached to the positioning post, and the limiting block is located on one edge of the base plate. In use, the four-way valve body is fitted onto the positioning post, with the side to be ground resting against the limiting block. The mounting cap is then tightened with bolts to secure the four-way valve body to the positioning post. The machine tool then grinds the end face. This utility model allows for quick and easy locking of the four-way valve body to the positioning post via the mounting cap, simplifying operation and improving processing efficiency.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0021] Example

[0022] Reference Figure 2-3 As shown, this utility model discloses a machining and positioning fixture for a four-way valve body 20, including a base plate 10. A positioning post 102 and a limiting block 103 are provided on the base plate 10. The positioning post 102 is used to position the main body of the four-way valve body 20, and the limiting block 103 is used to position the surface of the four-way valve body 20 to be machined, preventing the four-way valve body 20 from rotating.

[0023] Reference Figure 2-3 As shown, a detachable mounting cap 104 is mounted on the positioning post 102. Specifically, the cap 104 includes a disc and a pressure plate. The disc is mounted on the bottom of the pressure plate, and several pressure blocks protrude circumferentially from the pressure plate. In use, the four-way valve body 20 is fitted into the positioning post 102, and the cap 104 covers the four-way valve body 20 from above. The disc is placed inside the four-way valve body 20, and the pressure blocks of the pressure plate press against the edge of the four-way valve body 20. Bolts pass through the cap 104, and the disc is locked onto the positioning post 102, thus locking the four-way valve body 20 onto the positioning post 102.

[0024] Furthermore, a frustum 101 is further provided on the bottom of the positioning post 102 on the base plate 10. The frustum 101 is locked to the base plate 10 by bolts. When the four-way valve body 20 is fitted into the positioning post 102, the frustum 101 is placed inside the four-way valve body 20, which plays a positioning role in the placement of the four-way valve body 20.

[0025] Reference Figure 2-3As shown, two positioning rods 1021 are provided on the upper end of the positioning post 102, and the pressure cover 104 has two positioning holes 1041. When the pressure cover 104 is placed on the positioning post 102, the two positioning rods are inserted into the positioning holes 1041, and the pressure cover 104 can press the four-way valve body 20 vertically downward along the positioning rods 1021.

[0026] Reference Figure 2-3 As shown, the limiting block 103 is located on one side edge of the base plate 10. Specifically, the limiting block 103 includes two blocks, which are symmetrically arranged. The limiting blocks 103 are equipped with adjustable bolts 1031. When the end of the four-way valve body 20 to be ground is placed between the two limiting blocks 103, the adjusting bolts are adjusted to abut against the two sides of the four-way valve body 20, which fixes the end face of the four-way valve body 20 to be ground and prevents the end face of the four-way valve body 20 to be processed from being skewed.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
