DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] Please refer to Figures 1 to 3 , a three-way valve machining clamping table in the embodiment, including machining table 1, the number of two horizontal adjusting seat 5 and vertical adjusting seat 16, the top of machining table 1 is equipped with the clamping structure for three-way valve clamping and fixing, the top of machining table 1 is equipped with the adjusting structure for three-way valve clamping force balance.

[0025] Both the horizontal adjustment seat 5 and the vertical adjustment seat 16 are located on the top of the processing table 1.

[0026] The bottom of the processing table 1 is fixedly equipped with four support bases 2, and a base plate 19 is fixedly installed between the four support bases 2.

[0027] In this embodiment, the adjustment structure includes a bidirectional threaded rod 7 that is rotatably connected inside the horizontal adjustment seat 5 and the vertical adjustment seat 16. The horizontal adjustment seat 5 and the vertical adjustment seat 16 are both provided with movable holes. The bidirectional threaded rod 7 is rotatably connected inside the movable holes. Two limiting rings 18 are fixedly installed on the outer peripheral wall of the bidirectional threaded rod 7.

[0028] It should be noted that limiting the bidirectional threaded rod 7 improves the stability of the bidirectional threaded rod 7 during its movement.

[0029] In this embodiment, the outer peripheral wall of the bidirectional threaded rod 7 is threaded with two threaded rings 8. A mounting base 9 is fixedly installed on the outer peripheral wall of the threaded rings 8. A connecting base 10 is fixedly installed on the outer wall of one side opposite to the two mounting bases 9. An external pressure plate 11 is fixedly installed on the side of the connecting base 10 away from the mounting base 9. The external pressure plate 11 is arc-shaped, and the two external pressure plates 11 form a pressure sleeve. An arc-shaped rubber plate 12 is fixedly installed inside the external pressure plate 11. A limiting seat 13 is fixedly installed on the outer peripheral wall of the threaded rings 8. A limiting slide rod 14 is fixedly installed on the outer wall of one side opposite to the two limiting seats 13. Two limiting grooves are opened inside the transverse adjusting seat 5 and the vertical adjusting seat 16. Two adjacent limiting grooves are staggered. The limiting slide rod 14 is slidably connected inside the limiting groove, and the size of the limiting slide rod 14 is adapted to the size of the limiting groove.

[0030] It should be noted that, since the limiting slide bar 14 has a certain length, opening the limiting slide groove in a staggered manner can ensure the range of movement of the limiting slide bar 14.

[0031] In this embodiment, the clamping structure includes two mounting plates 3 fixedly installed on the top of the processing table 1. A first electric telescopic rod 4 is fixedly installed on the outer wall of the opposite side of the two mounting plates 3. Two lateral adjustment seats 5 are respectively movably installed on the opposite side of the two mounting plates 3. A lateral limiting clamp 6 is fixedly installed on the outer wall of the opposite side of the two lateral adjustment seats 5. A second electric telescopic rod 15 is fixedly installed on the top of the bottom plate 19. A vertical adjustment seat 16 is fixedly installed on the top end of the telescopic shaft of the second electric telescopic rod 15. A vertical limiting clamp 17 is fixedly installed on the top of the vertical adjustment seat 16. The outer walls of the opposite side of the two lateral adjustment seats 5 are respectively fixedly installed on the opposite end of the two first electric telescopic rods 4. Both the lateral limiting clamp 6 and the vertical limiting clamp 17 are in the shape of a frustum conical.

[0032] It should be noted that this design facilitates the clamping and fixing of the three-way valve, thus improving the stability of the three-way valve clamping.

[0033] It should be noted that the limiting ring 18 limits the bidirectional threaded rod 7, so that the bidirectional threaded rod 7 can only rotate inside the horizontal adjusting seat 5 and the vertical adjusting seat 16.

[0034] It should be noted that handles are installed at the top of the two upper bidirectional threaded rods 7, and a handle is installed at the right end of the lower bidirectional threaded rod 7.

[0035] It should be noted that the processing table 1 has an opening inside, which will move downward when the vertical limiting clamp 17 is not in use, so as to avoid blocking the horizontal limiting clamp 6.

[0036] The working principle of the above embodiments is as follows:

[0037] First, the first electric telescopic rod 4 is activated, causing the horizontal adjusting seat 5 to move closer to the three-way valve. When the two horizontal limiting clamps 6 move to the inside of the valve ports on the left and right sides of the three-way valve, the top bidirectional threaded rod 7 is rotated. At this time, the two external pressure plates 11 and the arc-shaped rubber plate 12 are moved closer to the valve ports and clamped externally through the action of the bidirectional threaded rod 7. Finally, the second electric telescopic rod 15 is activated, causing the vertical limiting clamp 17 to move upward. When the vertical limiting clamp 17 moves to the inside of the bottom valve port of the three-way valve, the bottom bidirectional threaded rod 7 is rotated. At this time, the arc-shaped rubber plate 12 at the bottom will clamp and wrap the outer peripheral wall of the bottom valve port of the three-way valve, thus balancing the clamping pressure inside and outside the three-way valve.

[0038] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
