DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figure 1 to Figure 2 As shown, a valve end cover processing device according to an embodiment of the present invention comprises a processing table 1, a conveyor belt 11 is arranged on the top of the processing table 1, and a plurality of receiving plates 2 are evenly arranged on the surface of the conveyor belt 11; a first connecting member is arranged between the receiving plate 2 and the conveyor belt 11;

[0036] A clamping assembly is provided at the top of the receiving plate 2; the clamping assembly is used to clamp and fix the end cover of the valve to be processed;

[0037] In actual drilling operations, workers need to install the valve end cover on the mounting seat each time a drilling operation is performed, and then remove the valve end cover when the drilling is completed; this process will take up a lot of time, so the drilling efficiency of the valve end cover needs to be further improved, which is not conducive to the drilling operation of large quantities of valve end covers; in order to solve the above problems, the embodiment of the present invention provides a conveyor belt 11, and when in use, the worker fixes the valve end cover to be punched on the clamping assembly on the receiving plate 2; then the conveyor belt 11 is controlled to rotate, and the conveyor belt 11 stops when the receiving plate 2 is moved to the drilling position through the first connecting member, and then the drilling operation is performed; At the same time, the staff is fixing other valve end covers to be punched to the receiving plates 2 at other positions of the conveyor belt 11; when the punching of the valve end cover on the previous receiving plate 2 is completed, the conveyor belt 11 transports another receiving plate 2 to the punching position to continue the punching operation; at the same time, the valve end cover to be punched continues to be installed on the next receiving plate 2; and the valve end cover after the punching is completed is removed; compared with a single punching operation of the valve end cover through a mounting seat, the whole process utilizes the time of the punching operation process to load and unload the valve end cover; thereby improving the punching efficiency of the valve end cover; it is particularly beneficial for the punching operation of large quantities of valve end covers.

[0038] like Figures 1 to 7 As shown, the clamping assembly includes a positioning block 21, and a pair of positioning blocks 21 are symmetrically arranged based on the center line of the receiving plate 2; a first hydraulic cylinder 22 is installed through the side of the positioning block 21, and a second connecting member 23 is arranged at the end of the output end of the first hydraulic cylinder 22; a push rod 24 is arranged at one end of the second connecting member 23 away from the first hydraulic cylinder 22;

[0039] The end of the push rod 24 located in the middle of the positioning block 21 is sleeved with a cylinder 25; a steel belt 26 is provided at one end of the cylinder 25 away from the push rod 24; a pair of baffles 27 are symmetrically provided on the side of the steel belt 26 facing the push rod 24 and based on the cylinder 25;

[0040] When clamping the valve end cover, for the valve end cover with a circular structure as a whole, a steel belt 26 is provided; specifically, when clamping, the valve end cover is placed at the center position of the top of the receiving plate 2; then the first hydraulic cylinder 22 is started, and the output end of the first hydraulic cylinder 22 drives the push rod 24 to move to the center position of the receiving plate 2 through the second connecting piece 23, and the push rod 24 located at the center position of the positioning block 21 drives the steel belt 26 to press against the side of the valve end cover through the cylinder 25; and the push rods 24 located on both sides of the valve end cover symmetrically drive the steel belt 26 to press against the side of the valve end cover; at the same time, The first hydraulic cylinders 22 on both sides of the center of the positioning block 21 drive the push rod 24 to further extend, thereby squeezing the surface of the steel belt 26, so that the steel belt 26 is deformed and attached to the side of the valve end cover, and stops when it is pressed against the baffle 27. The steel belt 26 is fully pressed against the side of the valve end cover; and is pressed and fixed by the push rod 24, thereby fixing the valve end cover on the receiving plate 2, and the force-bearing area of ​​the valve end cover is effectively increased compared to that fixed by the clamping plate, thereby preventing the valve end cover from being clamped and causing uniform deformation and damage, and the clamping effect of the valve end cover can be ensured by applying sufficient clamping force.

[0041] like Figures 2 to 8 As shown, two pairs of limit plates 28 are symmetrically arranged on the side of the steel belt 26 facing the push rod 24 and based on the cylinder 25; the spacing between the pair of limit plates 28 is the same as the diameter of the push rod 24; the end of the limit plate 28 away from the cylinder 25 is connected to the baffle 27; when the valve end cover is fixed by the steel belt 26, the ends of the push rod 24 located on both sides of the center position of the positioning block 21 are limited by the pair of limit plates 28, and when the steel belt 26 is bent, the push rod 24 is accurately guided to one side of the baffle 27 by the pair of limit plates 28 to prevent the steel belt 26 from changing its angle relative to the cylinder 25 when it is bent, causing the push rod 24 and the baffle 27 to be staggered; it should be pointed out that the limit plate 28 can be deformed synchronously with the steel belt 26.

[0042] A roller 241 is rotatably provided at one end of the push rod 24 close to the steel belt 26; when the end of the push rod 24 squeezes the steel belt 26 to deform it, the roller 241 at the end of the push rod 24 will press against the surface of the steel belt 26, thereby reducing the friction between the steel belt 26 and the push rod 24 and protecting the steel belt 26.

[0043] The second connecting member 23 includes a cylinder 231; a piston 232 is slidably connected inside the cylinder 231, a connecting rod 233 is vertically installed on the side of the piston 232, and the end of the connecting rod 233 away from the piston 232 is connected to the push rod 24; a first hose 234 is connected to the side of the cylinder 231; a pressure relief valve 235 is connected to the end of the first hose 234 away from the cylinder 231; the pressure relief valve 235 is installed on the top surface of the positioning block 21; when the push rod 24 presses against the surface of the steel belt 26, the air in the cylinder 231 is released. The body is compressed by squeezing the piston 232 through the connecting rod 233. When the gas pressure in the cylinder 231 reaches a certain level, the gas in the cylinder 231 is discharged through the pressure relief valve 235 at the end of the first hose 234, thereby avoiding excessive gas pressure in the cylinder 231. Based on the transmission of force, the pressure of the push rod 24 on the steel belt 26 is the same as the gas pressure in the cylinder 231. Therefore, the pressure of the push rod 24 on the steel belt 26 is synchronously limited, thereby preventing the steel belt 26 from clamping the valve end cover with excessive force to fix it, causing deformation and damage to the valve end cover.

[0044] A second hose 236 is provided on the side of the cylinder 231, and a transition air box 2361 is provided at one end of the second hose 236 away from the cylinder 231, and a one-way valve 2362 is provided at one end of the transition air box 2361 away from the second hose 236; a third hose 2363 is provided at the input end of the one-way valve 2362; an air pump 2364 is provided at one end of the third hose 2363 away from the one-way valve 2362; the air pump 2364 is installed on the surface of the conveyor belt 11; when in use, the air pump 2364 is started, and the air pump 2364 inflates the transition air box 2361 through the third hose 2363 and the one-way valve 2362, and the transition air box 2361 injects gas into the cylinder 231 through the second hose 236, so that the cylinder 231 is continuously inflated, ensuring that the cylinder 231 is full of gas and can be used continuously.

[0045] like Figure 3As shown, the first connecting member includes a support bar 20 and a support spring 201; one side of the support bar 20 is connected to the receiving plate 2, and the other side is connected to the surface of the conveyor belt 11; one end of the support spring 201 is connected to the conveyor belt 11, and the other end is connected to the receiving plate 2; the support bar 20 cooperates with the support spring 201 to support the receiving plate 2 on the surface of the conveyor belt 11; when the conveyor belt 11 drives the receiving plate 2 to move through the first connecting member, when it moves to the corner, the support spring 201 is deformed, so that the conveyor belt 11 will not be excessively pulled, and the support bar 20 supports the receiving plate 2, so that the receiving plate 2 maintains sufficient support effect when the valve end cover is punched.

[0046] like Figure 1 to Figure 2 As shown, a pair of slide grooves 3 are symmetrically provided on the surface of the receiving plate 2 based on the center line; a slider 31 is slidably connected inside the slide groove 3; an adjustment plate 32 is provided on one side of the slider 31 located at the notch of the slide groove 3; when clamping the valve end cover, the valve end cover needs to be placed at the center position of the top of the receiving plate 2, and when the staff operates, by pushing the slider 31 to slide in the slide groove 3, the slider 31 drives the adjustment plate 32 to push the valve end cover on the receiving plate 2, thereby adjusting the position of the valve end cover, which facilitates the adjustment process; it should be pointed out that the steel belt 26 symmetrically presses the valve end cover, so the steel belt 26 can also adjust the position of the valve end cover.

[0047] A scale code is set at the slot of the slide groove 3; when adjusting the position of the valve end cover, the staff can judge the adjustment accuracy of the valve end cover based on the scale code at the slot of the slide groove 3, and then operate accordingly.

[0048] A pair of second hydraulic cylinders 4 are symmetrically arranged on both sides of the processing table 1, and a limiting plate 41 is arranged at the output end of the second hydraulic cylinder 4; the limiting plate 41 is used to clamp and fix the end of the receiving plate 2; when performing the punching operation, the second hydraulic cylinder 4 is started, and the second hydraulic cylinder 4 drives the limiting plate 41 to press against the side of the receiving plate 2, thereby strengthening and fixing the position of the receiving plate 2, which is beneficial to improving the stability of the punching.

[0049] During work, the staff fixes the valve end cover to be punched on the clamping assembly on the receiving plate 2; then controls the conveyor belt 11 to rotate, and stops when the conveyor belt 11 drives the receiving plate 2 to move to the punching position through the first connecting piece, and then performs the punching operation; at the same time, the staff fixes other valve end covers to be punched to the receiving plate 2 at other positions of the conveyor belt 11; when the punching of the valve end cover on the previous receiving plate 2 is completed, the conveyor belt 11 transports another receiving plate 2 to the punching position and continues the punching operation; at the same time, continues to install the valve end cover to be punched on the next receiving plate 2; and removes the valve end cover after the punching is completed; the whole process is compared with a single through a mounting seat The valve end cover is punched, and the time of the punching operation process is used to load and unload the valve end cover; thus, the punching efficiency of the valve end cover is improved; it is particularly beneficial to the punching operation of a large number of valve end covers; when the valve end cover is clamped, for the valve end cover with an overall circular structure; a steel belt 26 is provided; specifically, when clamping, the valve end cover is placed at the center position of the top of the receiving plate 2; then the first hydraulic cylinder 22 is started, and the output end of the first hydraulic cylinder 22 drives the push rod 24 to move to the center position of the receiving plate 2 through the second connecting piece 23, and the push rod 24 located at the center position of the positioning block 21 drives the steel belt 26 to press against the side of the valve end cover through the cylinder 25; and the two ends of the valve end cover are located at the center of the valve end cover. The push rods 24 on the sides symmetrically drive the steel belt 26 to press against the side of the valve end cover; at the same time, the first hydraulic cylinders 22 located on both sides of the center of the positioning block 21 drive the push rods 24 to further extend, thereby squeezing the surface of the steel belt 26, so that the steel belt 26 is deformed and attached to the side of the valve end cover, and stops when it presses against the baffle plate 27. The steel belt 26 is fully pressed against the side of the valve end cover; and is pressed and fixed by the push rods 24, thereby fixing the valve end cover on the receiving plate 2, and the force-bearing area of ​​the valve end cover is effectively increased compared to fixing by the clamping plate, thereby preventing the valve end cover from being clamped and causing uniform deformation and damage, and the clamping effect of the valve end cover can be ensured by applying sufficient clamping force; wherein when fixed by the steel belt 26 When the valve end cover is formed, the ends of the push rod 24 located on both sides of the center position of the positioning block 21 are limited by a pair of limit plates 28. When the steel belt 26 is bent, the push rod 24 is accurately guided to the side of the baffle 27 by the pair of limit plates 28 to prevent the steel belt 26 from changing its angle relative to the cylinder 25 when it is bent, causing the push rod 24 and the baffle 27 to be misaligned. It should be pointed out that the limit plate 28 can be deformed synchronously with the steel belt 26. A roller 241 is rotatably provided at one end of the push rod 24 close to the steel belt 26. When the steel belt 26 is squeezed at the end of the push rod 24 to deform it, the roller 241 at the end of the push rod 24 will press against the surface of the steel belt 26, thereby reducing the friction between the steel belt 26 and the push rod 24, thereby protecting the steel belt 26.

[0050] When the push rod 24 is pressed against the surface of the steel belt 26, the gas in the cylinder 231 is compressed by squeezing the piston 232 through the connecting rod 233. When the gas pressure in the cylinder 231 reaches a certain level, the gas in the cylinder 231 is discharged through the pressure relief valve 235 at the end of the first hose 234, thereby avoiding excessive gas pressure in the cylinder 231. Based on the transmission of force, the pressing force of the push rod 24 on the steel belt 26 is the same as the gas pressure in the cylinder 231. Therefore, the pressing force of the push rod 24 on the steel belt 26 is synchronously limited, thereby preventing the steel belt from being damaged. 26 clamps the valve end cover with too much force, causing the valve end cover to deform and be damaged; when in use, start the air pump 2364, the air pump 2364 inflates the transition air box 2361 through the third hose 2363 and the one-way valve 2362, and the transition air box 2361 injects gas into the cylinder 231 through the second hose 236, so that the cylinder 231 is continuously inflated, ensuring that the gas in the cylinder 231 is full and can be used continuously; when the conveyor belt 11 drives the receiving plate 2 to move through the first connecting piece, when it moves to the corner When the conveyor belt 11 is pulled, the support spring 201 is deformed, so that the conveyor belt 11 will not be over-pulled, and the support strip 20 supports the receiving plate 2, so that the receiving plate 2 maintains sufficient support effect when the valve end cover is punched; when clamping the valve end cover, the valve end cover needs to be placed at the center position of the top of the receiving plate 2. When the staff operates, by pushing the slider 31 to slide in the slide groove 3, the slider 31 drives the adjustment plate 32 to push the valve end cover on the receiving plate 2, thereby adjusting the position of the valve end cover, which is convenient for the adjustment process; it should be pointed out that the steel belt 26 symmetrically presses the valve end cover, so the steel belt 26 can also adjust the position of the valve end cover; wherein the notch of the slide groove 3 is provided with a scale code; when adjusting the position of the valve end cover, the staff can judge the adjustment accuracy of the valve end cover according to the scale code at the notch of the slide groove 3, and then attach the staff to operate; wherein when performing the punching operation, the second hydraulic cylinder 4 is started, and the second hydraulic cylinder 4 drives the limiting plate 41 to press against the side of the receiving plate 2, thereby strengthening and fixing the position of the receiving plate 2, which is conducive to improving the stability of the punching.
