[0032] One or more embodiments of this specification provide a valve end cover punching device, such as Figures 1 to 6 As shown, it includes a body 101, on which a rotatable circular bearing platform 102 is mounted for bearing the end cover, and a punching assembly 401 is arranged above the bearing platform 102 for punching holes in the end cover.

[0033] At least three groups of clamping block assemblies 201 are also installed on the carrying platform 102, and the three groups of clamping block assemblies 201 are distributed in a circular array with the center of the carrying platform 102 as the center point;

[0034] A column 115 is provided below the carrying platform 102, a mounting platform 113 is rotatably mounted on the column 115, a fixed platform 109 that can move up and down is mounted on the mounting platform 113, a rotating seat 110 is sleeved on the outer periphery of the fixed platform 109, and an electric telescopic rod 112 is connected between the rotating seat 110 and the mounting platform 113 for driving the fixed platform 109 to move up and down;

[0035] At least three groups of connecting seats 111 are arranged in an array around the rotating seat 110. The three groups of connecting seats 111 are respectively connected to the pull rods 216 through the rotating shaft. The other end of the pull rod 216 is axially connected to the bottom of the clamping block assembly 201. The supporting platform 102 is provided with an avoidance groove 1022 for the movement of the pull rod 216. The electric telescopic rod 112 drives the fixed platform 109 to move up and down, pulls the pull rod 216 to move, and drives the three groups of clamping block assemblies 201 to gather or move away from the center at the same time.

[0036] The mounting platform 113 is connected to a transmission assembly 301 for driving the mounting platform 113 to rotate, thereby driving the supporting platform 102 to rotate and changing the punching position of the end cover.

[0037] When punching, the end cover is placed on the supporting platform 102 and located in the middle of the three groups of clamping block assemblies 201. Then the device is started, the electric telescopic rod 112 contracts, thereby pulling the rotating seat 110 and the fixed platform 109 downward, the pull rod 216 receives the pulling force, and pulls the three groups of clamping block assemblies 201 to gather toward the center, thereby clamping the valve end cover. After the clamping is completed, the punching assembly 401 punches the first hole in the end cover. After the first hole is completed, the transmission assembly 301 drives the mounting platform 113 to rotate, thereby driving the rotating seat 110 to rotate on the fixed platform 109. The pull rod 216 is located in the avoidance groove 1022, thereby driving the supporting platform 102 to rotate a certain angle, so that the punching assembly 401 processes the second hole, and so on, until all the holes are processed. The three groups of clamping block assemblies 201 cooperate with each other to achieve the fixation of the end cover, improve stability, and thus improve the punching accuracy.

[0038] In some optional specific embodiments, such as Figures 1 to 4 As shown, the clamping block assembly 201 includes a slider 202, and two sets of guide rails 214 are provided at the bottom of the slider 202. The support platform 102 is provided with a guide groove 1021 adapted to the guide rail 214, which is used to guide the slider 202 to be close to or away from the center of the array. A pull rod connecting part 215 is also installed at the bottom of the slider 202, and the pull rod connecting part 215 is connected to the pull rod 216 through a rotating shaft.

[0039] In some optional specific embodiments, such as Figures 1 to 5 As shown, the slider 202 is provided with a mounting groove 204, a clamping shaft 205 is installed inside the mounting groove 204, a rocker 206 is installed on the clamping shaft 205, one end of the rocker 206 is abutted and connected with a toggle plate 210, the toggle plate 210 is connected with an electric drive shaft 209, the electric drive shaft 209 is installed on the slider 202, the other end of the rocker 206 is connected with a connecting plate 207, the connecting plate 207 is connected with an auxiliary abutting block 208, the auxiliary abutting block 208 extends to the upper front of the slider 202, and a pneumatic component is connected to the side of the rocker 206 away from the toggle plate 210, which is used for driving the rocker 206 to rotate to the side where the end cover is located after the slider 202 is pressed against the end cover, so that the auxiliary abutting block 208 clamps the end cover from the upper edge of the end cover.

[0040] During use, under normal circumstances, the toggle plate 210 presses down the rocker 206, causing the rocker 206 to deflect toward the side away from the end cover, and the auxiliary holding block 208 is located above the slider 202 to avoid affecting the clamping action of the slider 202. When the slider 202 completes the clamping, the pneumatic component drives the rocker 206 to rotate toward the side where the end cover is located, so that the auxiliary holding block 208 clamps the end cover from the upper edge of the end cover to improve stability.

[0041] In some optional specific embodiments, such as Figures 1 to 5 As shown, this embodiment takes the need to drill three groups of holes as an example, the pneumatic component includes an air cavity platform 103 installed under the carrier 102, the air cavity platform 103 and the carrier 102 are rotatably connected, and a sealed bearing is installed around the contact surface between the air cavity platform 103 and the carrier 102, an air cavity 1031 is provided inside the air cavity platform 103, three adsorption holes 1032 are opened on the top of the air cavity 1031, and three accommodating holes 1023 adapted to the adsorption holes 1032 are opened on the carrier 102, and an adsorption block 213 is adapted to be installed in the accommodating hole 1023, and the adsorption block 213 is adapted to be installed in the adsorption block 213. 13 is connected with a connecting rope 212, and the connecting rope 212 is fixedly connected to one end of the rocker 206 close to the end cover. The piston cylinder 104 is connected to the lower part of the air cavity 1031, and a piston 105 is adapted to be installed in the piston cylinder 104. The piston 105 is fixedly connected with a connecting rod 106. The peripheral side of the connecting rod 106 is connected to a fixed platform 109 through fins. A guide cylinder 107 is sleeved on the outer periphery of the connecting rod 106. A plurality of avoidance openings 108 are provided on the guide cylinder 107. The avoidance openings 108 are used for the fins to move up and down. The bottom of the guide cylinder 107 is fixedly connected to the column 115.

[0042] During clamping, the rotating seat 110 moves downward, thereby driving one end of the multiple pull rods 216 to move downward and the other end to close, so that the three sliders 202 gather together. At this time, the connecting rod 106 pulls the piston 105 downward, so that negative pressure is generated in the air cavity 1031. When the three sliders 202 complete the clamping of the end cover, at this time, the adsorption block 213 located in the through hole 211 on the slider 202 is aligned with the accommodating hole 1023 and the adsorption hole 1032. The negative pressure adsorbs the adsorption block 213 and pulls the rocker 206, so that the auxiliary supporting block 208 clamps the end cover from above.

[0043] In some optional specific embodiments, a sealing gasket is provided at a portion of the bottom of the slider 202 located on the contact path of the receiving hole 1023 to maintain the sealing of the receiving hole 1023, and the slider 202 still covers the receiving hole 1023 when it is at the extreme position.

[0044] In some optional specific embodiments, a photoelectric switch is installed on the slider 202, and the photoelectric switch is used to monitor the position of the toggle plate 210. When the auxiliary abutment block 208 abuts against the end cover, the toggle plate 210 is lifted and the photoelectric switch is triggered. The photoelectric switch is electrically connected to a controller, and the controller is used to control the punching component 401 to perform the punching action. When the three groups of photoelectric switches are triggered at the same time, the controller controls the punching component 401 to perform the punching action, otherwise an alarm is issued.

[0045] Taking drilling three holes as an example, when the support platform 102 rotates to drill the second hole, only when the adsorption blocks 213 on the three sliders 202 are all adsorbed by the adsorption holes 1032, the rotation angle is determined to be correct. At this time, all three photoelectric switches are triggered, otherwise, it is determined that the rotation angle is deviated. Similarly, if n holes are to be drilled, n groups of sliders 202 are set.

[0046] In some optional specific embodiments, such as Figure 5 As shown, an arc-shaped abutting portion 203 is installed at the end of the slider 202 close to the center of the array.

[0047] In some optional specific implementations, such as Figures 1 to 6 As shown, the transmission assembly 301 includes a driving motor 302, the driving motor 302 is powered and connected to a transmission shaft 303, a driving bevel gear 306 is installed at the end of the transmission shaft 303, the driving bevel gear 306 is meshingly connected to a driven bevel gear 114, and the driven bevel gear 114 is fixedly installed at the bottom of the mounting platform 113, and a transmission hole 116 is opened on the body 101 for inserting the transmission shaft 303 into the body 101.

[0048] In some optional implementations, such as Figure 5 and Figure 6As shown, a rotating ring 304 is sleeved on the transmission shaft 303, and a plurality of light emitters are arranged in an array on the rotating ring 304. A light receiver 305 adapted to the light emitter is arranged on the side of the rotating ring 304, and the light receiver 305 stops rotating after receiving the light emitted by the rotating ring 304. By setting the time when the light emitter on the rotating ring 304 lights up, the rotation angle of the carrier 102 can be controlled. At the same time, when drilling, the light emitter and the light receiver 305 are opposite to each other, and it can be monitored whether the carrier 102 is deflected due to the drilling action during drilling.

[0049] In some optional specific embodiments, such as Figures 1 to 6 As shown, the punching assembly 401 includes a vertical plate 402 fixedly connected to the body 101, a telescopic sleeve 403 is installed on the top side of the vertical plate 402, a telescopic plate 404 is installed in the telescopic sleeve 403, a power plate is installed at the bottom of the telescopic plate 404, a transverse driving rod is connected between the power plate and the vertical plate 402, a screw seat 410 is connected to the bottom end of the power plate, a screw 408 is installed between the screw seat 410 and the telescopic plate 404, and a lifting rod is installed on the telescopic plate 404. The lowering motor 405 is used to drive the screw 408, and a lifting plate 409 is adapted to be installed on the screw 408. A guide column is also installed between the screw seat 410 and the telescopic plate 404 to guide the lifting and lowering of the lifting plate 409.

An avoidance hole 406 for avoiding the punching motor 407 is opened on the telescopic plate 404.

[0050] In some optional specific embodiments, in order to prevent air leakage in the air cavity 1031 due to aging of the device or other reasons, resulting in insufficient negative pressure in the air cavity 1031 , the air cavity 1031 is connected to an air pump to replenish the negative pressure in the air cavity 1031 .

[0051] The working principle of the present invention is as follows: when punching, the end cover is placed on the supporting platform 102 and is located in the middle of the three groups of clamping block assemblies 201. Then, the device is started, the electric telescopic rod 112 contracts, thereby pulling the rotating seat 110 and the fixed platform 109 downward, the pull rod 216 receives the pulling force, and pulls the three groups of clamping block assemblies 201 to gather toward the center, thereby clamping the valve end cover. After the clamping is completed, the punching assembly 401 punches the first hole in the end cover. After the first hole is completed, the transmission assembly 301 drives the mounting platform 113 to rotate, thereby driving the rotating seat 110 to rotate on the fixed platform 109. The pull rod 216 is located in the avoidance groove 1022, thereby driving the supporting platform 102 to rotate a certain angle, so that the punching assembly 401 processes the second hole, and so on, until all the holes are processed. The three groups of clamping block assemblies 201 cooperate with each other to achieve the fixation of the end cover, improve stability, and thus improve the punching accuracy.

[0052] At the same time, when clamping, the rotating seat 110 moves downward, thereby driving one end of the multiple pull rods 216 to move downward and the other end to close, so that the three sliders 202 gather together. At this time, the connecting rod 106 pulls the piston 105 downward, so that negative pressure is generated in the air cavity 1031. When the three sliders 202 complete the clamping of the end cover, at this time, the adsorption block 213 located in the through hole 211 on the slider 202 is aligned with the receiving hole 1023, and is aligned with the adsorption hole 1032. The negative pressure adsorbs the adsorption block 213, pulling the rocker 206 , so that the auxiliary holding block 208 clamps the end cover from above. Taking drilling three holes as an example, when the carrier 102 rotates to drill the second hole, only when the adsorption blocks 213 on the three sliders 202 are all adsorbed by the adsorption holes 1032, the rotation angle is determined to be correct. At this time, all three photoelectric switches are triggered, otherwise, it is determined that the rotation angle is deviated. By analogy, if n holes are to be drilled, n groups of sliders 202 are set, which can verify and detect the rotation angle of the workpiece and improve the drilling accuracy.
