Description

Technical Field

[0001] The utility model belongs to the technical field of lathe clamps, and specifically relates to a clamp structure for lathe processing of a three-way valve body. Background Art

[0002] In fluid control systems, three-way valves are used as a key fluid distribution component in various industrial fields, such as petrochemicals, water treatment, pharmaceuticals, and HVAC. As the core component, the design and processing quality of the three-way valve body directly affect the overall performance of the valve, including flow control accuracy, sealing performance, and service life. The structural feature of the three-way valve body is that it has multiple non-collinear fluid channels, which are interconnected through different end interfaces to achieve fluid distribution or mixing in different directions.

[0003] Among traditional processing methods, lathes occupy an important position in the rotary processing of cylindrical or symmetrical standard cylindrical workpieces due to their high precision and high efficiency. However, facing non-cylindrical or multi-end interface parts with complex geometric shapes such as three-way valve bodies, the processing methods of traditional lathes face significant technical challenges. Specifically, due to the irregular layout of the various end faces and fluid channels of the three-way valve body, and often lacking the characteristics of a cylindrical or symmetrical standard cylinder, it is difficult for traditional lathes to perform effective clamping and positioning, thus limiting their application in the processing of three-way valve bodies. In addition, the main processing content of the three-way valve body still includes the finishing of circular holes and end faces. These processes have extremely high requirements for surface quality and processing accuracy to ensure the sealing of the valve and the smoothness of the fluid flow. Although lathes have significant advantages in rotary processing, due to the limitations of their clamping methods, it is difficult to fully tap their potential in high-precision and high-efficiency processing.

[0023] Example:

[0024] See attached Figures 1 to 4. The present embodiment provides a fixture structure for lathe processing of a three-way valve body, which is used to solve the problem that the lathe processing fixture of the prior art cannot effectively clamp and position the three-way valve body 1, and includes a lathe processing fixture, on which a fixture body 3 is further fixed, and the workpiece that does not have a cylindrical or symmetrical standard cylindrical shape is clamped by the fixture body 3. The fixture body 3 of the present embodiment can be used to clamp the three-way valve body 1, and a positioning hole and a through hole are provided in the fixture body 3. By providing a detachable positioning plate 4 on the three-way valve body 1, the three-way valve body 1 is placed in the through hole, and the positioning plate 4 cooperates with the positioning hole, and then the three-way valve body 1 is fixed by the locking device of the positioning locking assembly, and then the processing is carried out. The width of the through hole of the clamp body 3 of the utility model is greater than the width of the three-way valve body 1, ensuring that the three-way valve body 1 can be placed in the through hole. The height of the through hole is slightly greater than the height of the three-way valve body 1, leaving redundant space for placing the three-way valve body 1, and the three-way valve body 1 is fixed in the through hole by a locking device.

[0025] The lathe processing fixture uses a three-jaw chuck 2, which has the advantages of high clamping force, good stability, large clamping range, high clamping accuracy, fast clamping and loosening speed, etc., and evenly applies clamping force from three directions. The fixture body 3 is an arc with a through hole in the middle. The width of the through hole is greater than the width of the three-way valve body 1. The three-way valve body 1 can rotate in the through hole before and after processing. A number of mounting threaded blind holes are evenly arranged above the processing surface of the three-way valve body 1. Specifically, four mounting threaded blind holes are arranged to form a rectangle. The positioning locking assembly includes a positioning plate 4, which is a rectangular plate with threaded through holes at four corners. The four threaded through holes on the positioning plate 4 are aligned with the four mounting threaded blind holes on the three-way valve body 1 and fixed by threaded pins 5. The positioning plate 4 can cooperate with the positioning holes of the fixture body 3.

[0026] The fixture body 3 is provided with a locking device, which includes two locking bolts 6. The fixture body 3 is provided with a locking mounting hole that matches the locking bolts 6. After the three-way valve body 1 is connected to the positioning plate 4, the positioning plate 4 is matched with the positioning hole. At this time, the three-way valve body 1 and the fixture body 3 are in a relatively movable state. The locking bolts 6 are screwed, and the locking bolts 6 extend downward and contact the positioning plate 4. The locking bolts 6 are continued to be screwed, and the positioning plate 4 and the three-way valve body 1 are abutted against the fixture body 3 to complete the positioning and locking of the three-way valve body 1. Then, the end surface is processed. The locking bolts 6 are provided with an auxiliary screwing wrench to assist in the screwing of the locking bolts 6, so that it is more stable after locking. A limit baffle 7 is set at one end of the positioning hole, so that the three-way valve body 1 can be positioned on the fixture body 3 more quickly.

[0027] When the valve body 1 is in the state of being moved horizontally, the locking bolt 6 is tightened to prevent the valve body 1 from moving horizontally and horizontally, and the locking bolt 6 is tightened to prevent the valve body 1 from moving horizontally and horizontally.
