DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] refer to Figure 1 The present invention provides a hydraulic tool for milling a sensing valve body, comprising a base plate 1 mounted on a milling machine via bolts. A first clamping portion 2, a second clamping portion 3, and a third clamping portion 4 are provided on the upper surface of the base plate 1. When the first clamping portion 2 clamps a valve body 5, the valve body 5 is in a vertical position, while when the second and third clamping portions 3 and 4 clamp the valve body 5, the valve body 5 is in a horizontal position. However, when the second clamping portion 3 clamps the valve body 5, the connecting plate on the valve body 5 faces downward, while when the third clamping portion 4 clamps the valve body 5, the connecting plate on the valve body 5 faces upward. This allows the valve body 5 to be clamped in three different positions, enabling milling of various angles of the valve body 5.

[0021] refer to Figure 2 The first clamping part 2 includes a cylinder 21 and a cross plate 22. The output shaft of the cylinder 21 is set parallel to the long side of the base plate 1, and the cross bar is set perpendicular to the long side of the base plate 1. The output end of the cylinder 21 is fixedly connected to a pressure strip 211. The length of the pressure strip 211 is greater than the distance between the axes of two adjacent valve bodies 5, so that the pressure strip 211 can achieve the purpose of clamping the two valve bodies 5 at the same time.

[0022] Two pairs of first locating pins 221 are fixedly connected to the cross plate 22. The first locating pins 221 are arranged on a side surface of the cross plate 22 near the pressure strip 211. The first locating pins 221 and the pressure strip 211 are arranged at the same height. The spacing between the two first locating pins 221 in a pair is set to the same spacing as the two connecting holes on the connecting plate. That is, the two connecting holes on the valve body 5 can be sleeved on the first locating pins 221, thereby locating and limiting the valve body 5. When clamping, one side surface of the connecting plate is abutted against the cross plate 22, and the pressure strip 211 is abutted against the side end surface of the valve body 5 facing away from the connecting plate. The valve body 5 is then clamped by the pressure strip 211 and the cross bar.

[0023] The bottom plate 1 is also provided with an avoidance opening 11, which is arranged between the cylinder 1 21 and the cross plate 22, so that when the first clamping part 2 clamps the valve body 5, the bottom end of the valve body 5 can extend into the avoidance opening 11 to avoid interference with the bottom plate 1.

[0024] The second clamping portion 3 includes a horizontal plate 31, which is arranged parallel to and fixedly connected to the base plate 1. Two pairs of pressure blocks 32 are mounted on the upper surface of the horizontal plate 31. The pressure blocks 32 are rotatably connected to bolts that are threadedly connected to the horizontal plate 31. That is, rotating the bolts can drive the pressure blocks 32 to move up and down.

[0025] A valve body 5 is arranged between any pair of pressure blocks 32 , and the surface of the connecting plate is downwardly arranged to be in close contact with the horizontal plate 31 . The bolts are adjusted by turning the pressure blocks 32 to press the connecting plate, thereby achieving a clamping effect on the valve body 5 .

[0026] A second locating pin 311 is fixedly connected to each pressure block 32 on the horizontal plate 31. The second locating pin 311 is located directly below the pressure block 32. The spacing between the two second locating pins 311 in a pair is the same as the spacing between the two connecting holes on the connecting plate. In other words, the two connecting holes on the valve body 5 can be fitted over the second locating pins 311, thereby positioning and limiting the valve body 5. After the connecting plate is positioned using the second locating pins 311, the bolts are rotated to drive the pressure block 32 downward to clamp the connecting plate, thereby clamping the valve body 5.

[0027] The third clamping part 4 includes a second cylinder 41 and a vertical plate 42. The vertical plate 42 is arranged parallel to the long side of the bottom plate 1. The vertical plate 42 is used to abut against the flange end face of the valve body 5. The output end of the second cylinder 41 is fixedly connected to the original top block, and the top block is adapted to the end of the valve body 5 away from the vertical plate 42.

[0028] The top block is set to be stepped, and the end with a small diameter of the top block is smaller than the inner diameter of the valve body 5. During installation, the end with a small diameter can be inserted into the interior of the valve body 5, and the end with a large diameter of the top block is larger than the inner diameter of the valve body 5, that is, the end with a large diameter can be against one end of the valve body 5.

[0029] Two cylinders 41 are provided so as to be able to simultaneously clamp two valve bodies 5. Two positioning blocks are fixedly connected to the vertical plate 42 corresponding to the cylinders 41. The positioning blocks are arranged in a circular shape, and the diameter of the positioning blocks is set to be the same as the inner diameter of the valve body 5. During installation, the positioning blocks can be inserted into the interior of the valve body 5.

[0030] A U-shaped limit frame 43 is also installed between the vertical plate 42 and the cylinder 2 41. The valve body 5 is placed inside the limit frame 43. The bottom end of the limit frame 43 is telescopically connected to the bottom plate 1 through three telescopic rods, and springs are sleeved on the telescopic rods on both sides. The top end of the spring is against the limit frame 43, and the bottom end of the spring is against the bottom plate 1. Positioning notches are provided on the two top ends of the limit frame 43, which correspond to the two connecting holes on the connecting plate. By using a top screw to thread the connecting hole and then tightening the top screw to the positioning notch, the valve body 5 can be further limited.

[0031] To sum up, the utility model can achieve the clamping effect of the valve body 5 at different angles through the arrangement of the first clamping part 2, the second clamping part 3 and the third clamping part 4, thereby meeting the milling process of different positions on the valve body 5, and replacing the processing surface only needs to be performed on different clamping parts, and there is no need to replace different fixtures on the machine tool, which further saves the time of replacing the fixture and greatly improves the processing efficiency.
