[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] The rotating assembly 22 comprises a T-shaped cylinder 221, and a plurality of rectangular grooves 222 are formed in a circular array on the upper end of the T-shaped cylinder 221, and a rotating shaft 223 is provided in each rectangular groove 222 for rotatably connecting the movable housing 23;

[0049] The limiting assembly 25 includes a cylinder 251; a spiral piece 252 is provided on the outer wall of the cylinder 251, and a C-shaped ring 253 is integrally provided on the top of the cylinder 251; the spiral piece 252 is arranged 180 degrees around the cylinder 251, and the opening direction of the C-shaped ring 253 is toward the initial end of the spiral piece 252.

[0050] By adopting the above technical solution, when installing the valve seat, the valve seat is first placed on the movable shell 23. When the rotating component 22 rotates, the raised block 231 on the movable shell 23 gradually flips along the guidance of the spiral sheet 252. At this time, the movable shell 23 rotates around the rotating shaft 223. When it rotates to the C-ring 253, it is in an upright state and closed with the fixed shell 24, thereby achieving the fixation of the valve seat.

[0051] The above fixing method does not require cylinders, bolts and other fixing components for fixing, and does not require manual participation; and a plurality of sets of movable shells 23 and fixed shells 24 are provided on the rotating component 22, so that a plurality of valve seats can be clamped one by one, and the punching equipment punches holes in the plurality of valve seats one by one; in this process, the equipment can be processed without stopping, and there is no waiting time in the middle; compared with traditional punching equipment, the punching efficiency of the valve seat is doubled.

[0052] Specifically, both the fixed housing 24 and the movable housing 23 are provided with cavities for installing the valve seat of the regulating valve, wherein a magnetic block is embedded in the cavity inside the movable housing 23 .

[0053] By adopting the above technical solution, the magnetic block can be set to attract the valve seat to prevent the valve seat from falling when the movable shell 23 is turned over, thereby ensuring the positioning accuracy of the valve seat and the fixed shell 24 and the movable shell 23 after closing.

[0054] Please see attached Figure 12 to Figure 14 In this embodiment, an outer cylinder 226 is welded to the bottom of the T-shaped cylinder 221, and a gear ring 225 is installed at the lower end of the outer cylinder 226; the gear ring 225 is meshed and connected with the gear 3, wherein the gear 3 is installed on the rotating motor 4.

[0056] In this embodiment, a limiting blocking rod 224 is disposed on the inner side of each rectangular slot 222 and close to the outer edge. The height of the limiting blocking rod 224 is lower than the rotating shaft 223 .

[0057] By adopting the above technical solution, the limit stop rod 224 plays a certain limiting role on the movable shell 23, ensuring that the movable shell 23 is in a horizontal state when it is against the limit stop rod 224, and the raised block 231 on the inner side of the movable shell 23 is located below the initial end of the spiral piece 252; when the movable shell 23 is in the above state, the valve seat can be better fixed and installed, and when the T-shaped cylinder 221 rotates, the function of the raised block 231 to deflect along the spiral piece 252 can be utilized to realize the closure of the fixed shell 24 and the movable shell 23.

[0058] See also Fig.10 In this embodiment, the two ends of the C-shaped ring 253 are end a and end b, wherein end a is the starting end and end b is the ending end; end b is arranged in an arc shape with respect to the initial end of the spiral sheet 252.

[0059] Specifically, the gap between the cylinder 251 and the inner wall of the T-shaped cylinder 221 is the length of the protruding block 231 ; the gap between the C-shaped ring 253 and the inner wall of the T-shaped cylinder 221 is the width of the protruding block 231 .

[0060] By adopting the above technical solution, the rotating assembly 22 rotates clockwise, and the protruding block 231 deflects along the spiral piece 252. When the protruding block 231 rotates to the end a, the protruding block 231 is in an upright state, so that the movable housing 23 stands upright and the valve seat is buckled in the fixed housing 24.

[0061] After the valve seat is processed, as the rotating component 22 continues to rotate, when the protrusion block 231 rotates to the b end, the activity space of the protrusion block 231 becomes larger, the movable shell 23 deflects outward, and unfolds into a horizontal state. At this time, the protrusion block 231 is just located at the initial end of the spiral piece 252, which facilitates the removal of the processed valve seat.

[0062] Please see attached Figure 1 To Attachment Figure 4 In this embodiment, two slide rails 5 are fixed to the frame body 1, each slide rail 5 is slidably connected to a slide seat 6, and the two slide seats 6 are fixed to the bottom of the vertical frame 7; a screw feed assembly 13 is also provided at the bottom of the vertical frame 7;

[0063] A longitudinal screw drive assembly 10 is also installed on the inner side of the vertical frame 7 , and a transverse linear module 8 is installed on the longitudinal screw drive assembly 10 ; a drill assembly 9 is provided on the transverse linear module 8 .

[0064] By adopting the above technical solution, when the screw feed assembly 13 is in motion, it can drive the vertical frame 7 to move forward and backward along the slide rail 5 through the slide seat 6 arranged at the bottom; the setting of the horizontal linear module 8 can drive the drill assembly 9 to move left and right, thereby realizing the hole opening operation at different positions on the same valve seat;

[0065] The longitudinal screw drive assembly 10 can drive the transverse linear module 8 and the drill assembly 9 to move up and down, thereby achieving control of the valve seat opening depth.

[0066] In this embodiment, a support arm 11 is fixed to one side of the upper end of the vertical frame 7 ; and a tool changing mechanism 12 is mounted on one end of the support arm 11 away from the vertical frame 7 .

[0067] By adopting the above technical solution, a plurality of drill bits are installed on the tool changing mechanism 12, and the tool changing function can be realized more conveniently when opening holes of different sizes.

[0068] The working principle is: when installing the valve seat, first place the valve seat on the movable shell 23, and the limit stop rod 224 plays a certain limiting role on the movable shell 23, ensuring that the movable shell 23 is in a horizontal state when it is against the limit stop rod 224, and the raised block 231 on the inner side of the movable shell 23 is located below the initial end of the spiral piece 252; when the movable shell 23 is in the above state, the valve seat can be better fixed and installed, and when the T-shaped cylinder 221 rotates, the raised block 231 can be used to deflect along the spiral piece 252 to realize the closing of the fixed shell 24 and the movable shell 23; due to the setting of the magnetic suction block, the valve seat can be sucked in to prevent the valve seat from falling when the movable shell 23 is flipped, thereby ensuring the positioning accuracy of the valve seat and the fixed shell 24 and the movable shell 23 after closing.

[0069] When the rotating motor 4 drives the gear 3 to rotate, the T-shaped cylinder 221 is driven to rotate in cooperation with the gear ring 225, so that the valve seat is placed below the drill assembly 9; when the screw feed assembly 13 is in motion, it can drive the vertical frame 7 to move forward and backward along the slide rail 5 through the slide seat 6 set at the bottom; the setting of the horizontal linear module 8 can drive the drill assembly 9 to move left and right, thereby realizing the hole opening operation at different positions on the same valve seat;

[0070] The longitudinal screw drive assembly 10 can drive the transverse linear module 8 and the drill assembly 9 to move up and down, thereby achieving control of the valve seat opening depth.

[0071] After the valve seat is processed, as the rotating component 22 continues to rotate, when the protrusion block 231 rotates to the b end, the activity space of the protrusion block 231 becomes larger, the movable shell 23 deflects outward, and unfolds into a horizontal state. At this time, the protrusion block 231 is just located at the initial end of the spiral piece 252, which facilitates the removal of the processed valve seat.

[0072] The processing and fixing method of the valve seat does not require cylinders, bolts and other fixing components for fixing, and does not require manual participation; and a plurality of sets of movable shells 23 and fixed shells 24 are provided on the rotating component 22, so that a plurality of valve seats can be clamped one by one, and the punching equipment punches holes in the plurality of valve seats one by one; in this process, the equipment can be processed without stopping, and there is no waiting time in the middle; compared with traditional punching equipment, the punching efficiency of the valve seat is doubled.
