Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, specifically to a three-way valve processing center. Background Technology

[0002] A three-way valve is a fluid control component with three flow channels in its body. It includes merging / diverting valves (two inlets and one outlet) and splitting valves (one inlet and two outlets), as well as L-type and T-type flow channel designs. Three-way valves change the direction of medium flow, achieving diversion, merging, or path switching, and are widely used in petroleum, medical, and HVAC fields, suitable for various media such as water, steam, and pharmaceuticals. The main body of a three-way valve typically requires three drilling operations on a drilling machine, followed by three tapping operations. Current three-way valves still use continuous single drilling to achieve three opening operations, resulting in cumbersome multi-point drilling processes, affecting processing efficiency, and making it difficult to guarantee the accuracy of the three drilling points. Therefore, it is necessary to propose a three-way valve machining center with simpler processing procedures, higher processing efficiency, and better processing accuracy. Summary of the Invention

[0018] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0019] like Figure 1 As shown, the three-way valve machining center includes a machining base 2, a worktable 3 mounted on the machining base 2, a three-axis machining device 1 mounted on the side of the worktable 3, and a movable tool holder assembly 5 mounted on the side of the three-axis machining device 1. Chip removal grooves 21 are provided on both the front and rear sides of the machining base 2, and chip removal augers 22 are installed within the chip removal grooves 21. The chip removal grooves 21, in conjunction with the chip removal augers 22, discharge the machining debris generated during machining from the machining base 2. A tool changing drive assembly 112 is provided on the three-axis machining device 1, and each tool holder assembly 5 is used to store several tools 6 of the three-axis machining device 1. A frame 4 is provided on the machining base 2, and a movable vertical clamping cylinder 45 is provided on the frame 4. Three valve support blocks 31 are provided on the worktable 3, and each valve support block 31 has a V-shaped limiting port at its top. The vertical clamping cylinder 45, in conjunction with the valve support blocks 31, is used to position the valve during machining. Specifically, each valve support block 31 is L-shaped, and the tops of the three valve support blocks 31 are fixed to the T-shaped through grooves on the worktable 3 by T-bolts. The three valve support blocks 31 are distributed in a T-shape and are used to support the bottom of the three-way valve to be processed. They work in conjunction with the vertical clamping cylinder 45 to clamp the top of the three-way valve to be processed, thereby achieving the processing and fixing of the three-way valve and facilitating the processing of the three-way valve. Figure 2 and 3As shown, the frame 4 includes a rear U-shaped bracket 41, two front L-shaped brackets 42 fixedly connected to the rear U-shaped bracket 41, and pressure block brackets 43 mounted on the two front L-shaped brackets 42. Each front L-shaped bracket 42 and pressure block bracket 43 are connected by a linear motion guide rail 44. The fixed end of the vertical clamping cylinder 45 is fixedly connected to the pressure block bracket 43, and a clamping block 46 is provided at the extended end of the pressure block bracket 43. The linear motion guide rail 44 can be a linear motion module. Specifically, the linear motion guide rail 44 drives the pressure block bracket 43 to slide back and forth on the L-shaped bracket 42. The vertical clamping cylinder 45 is fixed at the bottom of the pressure block bracket 43. Thus, the linear movement of the linear motion guide rail 44, combined with the linear lifting and lowering of the vertical clamping cylinder 45, achieves the clamping and fixing operation of the top of the three-way valve to be processed by using the clamping block 46 of the vertical clamping cylinder 45.

[0020] like Figure 4 As shown, the tool holder assembly 5 includes a tool holder fixing base 51, a tool moving bracket 52, and a tool holder cylinder 53. The tool holder fixing base 51 is fixed on the machining base 2. The tool moving bracket 52 is slidably mounted on the tool holder fixing base 51. The telescopic end of the tool holder cylinder 53 is fixedly connected to the tool holder fixing base 51, and the fixed end of the tool holder cylinder 53 is fixedly connected to the tool moving bracket 52. A tool placement plate 55 is provided on the tool moving bracket 52. The tool placement plate 55 is provided with several transverse U-shaped tool slots 56, and U-shaped limiting protrusions 57 are provided inside the U-shaped tool slots 56. Two tool holder guide rails 54 are provided on the tool holder fixing base 51. A tool holder slider that cooperates with the tool holder guide rails 54 is fixed on the tool moving bracket 52. The tool holder guide rails and the tool holder slider cooperate to realize the linear guidance operation of the tool moving bracket 52. Specifically, when the tool holder cylinder 53 extends to its closest stroke, it moves the tool moving bracket 52, the tool placement plate 55, and the tool 6 to the outermost position, ensuring that the tool holder assembly 5 does not interfere with the machining operation of the three-axis machining device 1. When the tool holder cylinder 53 extends to its farthest stroke, it moves the tool moving bracket 52, the tool placement plate 55, and the tool 6 to the innermost position, and the tool holder assembly 5, in conjunction with the tool changing drive assembly 112, performs the tool changing operation of the tool 6. In this embodiment, three tool holder assemblies 5 are provided: a first tool holder assembly 501, a second tool holder assembly 502, and a third tool holder assembly 503. The first and second tool holder assemblies 501 and 502 are mounted on the same tool holder fixed base 51 and tool moving bracket 52. The tool holder cylinder 53 is positioned at a 45-degree angle between the first machining center 101 and the second machining center 102, and the third tool holder assembly 503 is positioned at a 45-degree angle between the second machining center 102 and the third machining center. Meanwhile, the first tool post assembly 501 corresponds to the tool change of the first machining center 101, the second tool post assembly 502 corresponds to the tool change of the second machining center 102, and the third tool post assembly 503 corresponds to the tool change of the third machining center 103.

[0021] like Figure 5 and 6 As shown, the three-axis machining device 1 includes an X-axis base 11, a linearly movable Y-axis base 12, a linearly movable Z-axis body 13, a linearly lifting machining slide 111, and a tool changing drive assembly 112. The Y-axis base 12 is mounted on the X-axis base 11, the linearly movable Z-axis body 13 is mounted on the Y-axis base 12, the lifting machining slide 111 is mounted on the Z-axis body 13, and the tool changing drive assembly 112 is mounted on the lifting machining slide 111.

[0022] A rotatable X-axis lead screw 15 is mounted on the X-axis base 11. An X-axis lead screw slider that mates with the X-axis lead screw 15 is fixed to the bottom of the Y-axis base 12. One end of the X-axis lead screw 15 is fixedly connected to an X-axis motor. Two X-axis guide rails 14 are provided on the X-axis base 11, and an X-axis slider that mates with the X-axis guide rails 14 is provided at the bottom of the Y-axis base 12. Specifically, the X-axis motor drives the X-axis lead screw slider to move the Y-axis base 12 along the X-axis.

[0023] A rotatable Y-axis lead screw 17 is mounted on the Y-axis base 12. A Y-axis lead screw slider that mates with the Y-axis lead screw 17 is fixed to the bottom of the Z-axis body 13. A Y-axis motor is fixedly connected to one end of the Y-axis lead screw 17. Two Y-axis guide rails 16 are provided on the Y-axis base 12, and a Y-axis slider that mates with the Y-axis guide rails 16 is provided at the bottom of the Z-axis body 13. Specifically, the Y-axis motor drives the Y-axis lead screw slider to move the Z-axis body 13 along the Y-axis.

[0024] A rotatable Z-axis lead screw 19 is mounted on the Z-axis machine body 13. A Z-axis lead screw slider that mates with the Z-axis lead screw 19 is fixed on the lifting machining slide 111. A lifting motor 110 is fixedly connected to the top of the Z-axis lead screw 19. Two Z-axis guide rails 18 are provided on the Z-axis machine body 13, and Z-axis sliders that mate with the Z-axis guide rails 18 are provided on the lifting machining slide 111. Specifically, the lifting motor 110 drives the Z-axis lead screw slider to move the lifting machining slide 111 along the Z-axis.

[0025] like Figure 7 , 8As shown in Figure 9, the tool changing drive assembly 112 includes a chuck 1121 rotatably mounted on the lifting machining slide 111, a drive motor 1122, and a tool ejection cylinder 1126. A driven gear 1124 is fixed to the rear side of the chuck 1121, and a driving gear 1123 is fixed to the output end of the drive motor 1122. The driven gear 1124 and the driving gear 1123 are connected by a drive belt 1125. Specifically, the drive motor 1122 drives the chuck 1121 and the tool 6 to rotate together, thereby using the tool 6 to process the three-way valve to be processed. The chuck 1121 and the tool ejection cylinder 1126 are coaxially coupled. The tool ejection cylinder 1126 ejects the tool 6 to be replaced from the chuck 1121, thereby storing the tool 6 in the U-shaped tool slot 56 of the tool holder assembly 5.

[0026] Working process and principle: Before processing, the tool holder cylinder 53 of the tool holder assembly 5 extends and retracts to its maximum stroke. The three-axis machining device 1 moves the chuck 1121 on the lifting machining slide 111 to the side of the corresponding tool 6. Then, the three-axis machining device 1 controls the chuck 1121 to move so that the tool 6 is inserted into the chuck 1121. After the tool 6 is successfully docked and fixed with the chuck 1121, the three-axis machining device 1 controls the chuck 1121 to slide the tool 6 laterally out of the tool holder assembly 5. After the tool 6 has completely left the tool holder assembly 5, the tool holder cylinder 53 of the tool holder assembly 5 extends and retracts to its minimum stroke, and moves the tool moving bracket 52 to the side that does not affect the operation of the three-axis machining device 1, thus completing the tool loading operation. When a tool change is required during machining in the three-axis machining device 1, the tool change operation is basically the same as the tool loading operation. The difference is that the three-axis machining device 1 needs to move the tool 6 to the empty U-shaped tool slot 56 on the tool placement plate 55, put the tool 6 into the empty U-shaped tool slot 56, and then select the corresponding tool 6 to perform the tool loading operation.
