Description

Technical Field

[0002] A butterfly valve is a valve that has a disc as the opening and closing part, which can be opened and closed by rotating 90° around its axis. The butterfly valve is mainly composed of five parts: valve body, butterfly plate, valve seat, valve stem, and driver. The driver is connected to the valve body. The rotation of the driver drives the rotation of the valve stem, and the rotation of the valve stem drives the rotation of the butterfly plate. The valve is opened and closed by the rotation of the butterfly plate.

[0049] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0050] As attached Figure 1 As shown, an automated butterfly valve processing device includes a frame 1, a longitudinal slide 2, a positioning mechanism 3, a clamping mechanism 4, a calibration mechanism 6, a processing mechanism 7, a tool installation mechanism 8 and a tool switching mechanism 9.

[0051] As attached Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, a longitudinal base 11 is provided on the upper surface of the frame 1, and a longitudinal slide 2 is provided on the longitudinal base 11, and the longitudinal slide 2 is provided on the longitudinal base 11 for longitudinal movement, and a positioning mechanism 3 is provided on the longitudinal slide 2, and the specific positioning mechanism 3 includes a fixed column 31, a pusher 32 and a positioning block 34, the fixed column 31 is provided on the upper surface of the longitudinal slide 2, and a plurality of positioning blocks 34 are provided on the circumferential outer side of the fixed column 31, and the positioning block 34 is a fan-shaped structure, and a positioning groove 342 is provided on the top of the positioning block 34, and the positioning block 34 is provided on the side of the fixed column 31 for synchronous extension and contraction. When processing the butterfly plate 51, by extending and contracting the positioning block 34, when the butterfly plate 51 is mounted between the plurality of positioning blocks 34, the butterfly plate 51 can be just placed in the space surrounded by the positioning grooves 342 on the plurality of positioning blocks 34, which plays a positioning role for the butterfly plate 51, and at the same time, the convex strip 511 on the butterfly plate 51 is placed in the gap between the adjacent positioning blocks 34 to avoid affecting the placement of the butterfly plate 51. When processing the valve body 52 , by telescoping the positioning block 34 , when the valve body 52 is placed on the upper surface of the longitudinal slide 2 , the valve body 52 can be sleeved on the outside of the positioning block 34 , and the outer surfaces of several positioning blocks 34 can contact the inner wall of the valve body 52 , thereby playing a positioning role for the valve body 52 .

[0052] Among them, as attached Figures 5 to 7 As shown, the pushing member 32 is used to realize the synchronous extension and retraction of the positioning block 34. Specifically, a mounting groove 21 is penetrated on the side of the longitudinal slide 2 facing the transverse base 12, and a plurality of openings penetrating into the mounting groove 21 are provided on the upper surface of the longitudinal slide 2. The pushing member 32 is located in the mounting groove 21 and is lifted and lowered. The pushing member 32 is driven by a positioning piston cylinder 35 provided in the mounting groove 21. The pushing member 32 and the fixed column 31 are parallel to each other, and the fixed column 31 and the pushing member 32 are coaxial. A connecting arm 33 is hinged at the bottom of the positioning block 34, and the connecting arm 33 is hinged to the upper surface of the pushing member 32 after passing through the opening. At the same time, a transverse guide rod 341 is provided on the circumferential inner wall of the positioning block 34, and a plurality of guide holes 311 are provided on the circumferential outer side of the fixed column 31. When the positioning block 34 is located outside the fixed column 31 and retracts, the transverse guide rod 341 slides in the guide hole 311. When in use, the pushing member 32 is driven to rise and fall by the positioning piston cylinder 35. During the process, the pushing member 32 drives the positioning block 34 to move through the connecting arm 33. In addition, due to the guiding effect of the guide hole 311 on the transverse guide rod 341, the positioning block 34 can only be located on the outside of the fixed column 31 and extend and retract synchronously, so as to realize the positioning of the butterfly plate 51 or the valve body 52.

[0053] Further, as attached Figure 6 and Figure 7As shown, a vertical guide rod 313 is provided on the bottom surface of the fixed column 31, and the vertical guide rod 313 can slide through the pusher 32, and the vertical guide rod 313 can guide the lifting and lowering of the pusher 32 to avoid the risk of the pusher 32 being skewed during the lifting and lowering process. In addition, a spring 36 is sleeved on the outer side of the vertical guide rod 313, and the two ends of the spring 36 respectively abut against the bottom surface of the fixed column 31 and the upper surface of the pusher 32, and the spring 36 can make the lifting and lowering of the pusher 32 more stable.

[0054] In addition, as attached Figure 3 , Figure 8 , Fig. 9 , Fig.19 and Fig. 20 As shown, a clamping mechanism 4 is provided on the longitudinal slide 2 for clamping the butterfly plate 51 or the valve body 52 after positioning. The clamping mechanism 4 includes a truss 41 and a clamping plate 42. The clamping plate 42 is fixed to the bottom surface of the truss 41. The truss 41 is arranged above the longitudinal slide 2 for lifting. Specifically, both ends of the bottom surface of the truss 41 are provided with a light rod 43, and the light rod 43 is connected to the piston of the clamping piston cylinder 44. The clamping piston cylinder 44 is arranged in the mounting groove 21 of the longitudinal slide 2. When the butterfly plate 51 is positioned on the longitudinal slide 2, the upper surface of the butterfly plate 51 is higher than the upper surface of the positioning block 34. When the valve body 52 is positioned on the longitudinal slide 2, the upper surface of the valve body 52 is higher than the upper surface of the positioning block 34. Then, the truss 41 is driven to rise and fall by the pressing piston cylinder 44 until the pressing plate 42 is pressed on the upper surface of the butterfly plate 51 or the upper surface of the valve body 52, thereby pressing and fixing the butterfly plate 51 on the positioning block 34 and the valve body 52 on the longitudinal slide 2. The bottom surface of the pressing plate 42 is provided with a notch 421. When the pressing plate 42 is pressed on the upper surface of the butterfly plate 51, the convex strip 511 of the butterfly plate 51 is located in the notch 421 to ensure that the pressing plate 42 can smoothly press and fix the butterfly plate 51. At the same time, a clearance groove 312 can also be set on the upper surface of the fixing column 31 according to actual needs, so that when the butterfly plate 51 is placed in the positioning groove 342 of the positioning block 34, the convex strip 511 of the butterfly plate 51 is located in the clearance groove 312, thereby preventing the convex strip 511 from affecting the placement of the butterfly plate 51 in the positioning groove 342.

[0055] As attached Figure 1 and Fig.10As shown, a calibration mechanism 6 for calibrating the butterfly plate 51 and the valve body 52 is provided on the frame 1. The calibration mechanism 6 includes a push rod 62 and an electric push rod 61 for driving the push rod 62 to extend and retract. The electric push rod 61 is fixed to the frame 1 through a calibration mounting frame 63. When people place the butterfly plate 51 and the valve body 52 on the positioning block 34 and the longitudinal slide 2 for positioning, people can roughly adjust the processing angles of the butterfly plate 51 and the valve body 52, and then move the butterfly plate 51 and the valve body 52 to the calibration station through the longitudinal slide 2, and then drive the push rod 62 to extend outward through the electric push rod 61, so that the conical tip of the push rod 62 is inserted into the initial shaft hole 53 of the butterfly plate 51 or the valve body 52 to align with the center. During the process, the butterfly plate 51 or the valve body 52 rotates slightly to complete the calibration, and finally the butterfly plate 51 or the valve body 52 is clamped and fixed by the clamping plate 42. After calibration, it can be ensured that the initial shaft hole 53 on the butterfly plate 51 or the valve body 52 will not be skewed during subsequent reprocessing, thereby ensuring the processing quality.

[0056] As attached Figure 1 , Figure 2 , Fig.11 and Fig.12As shown, two transverse bases 12 are provided on the upper surface of the frame 1, and the two transverse bases 12 are respectively provided on both sides of the longitudinal base 11, and a processing mechanism 7 is provided on each of the two transverse bases 12, and the processing mechanism 7 includes a transverse slide 71, a spindle box 72 and a pneumatic three-jaw chuck 73. The transverse slide 71 is provided on the transverse base 12 and moves transversely, and the spindle box 72 is provided on the transverse slide 71 and moves transversely, and the spindle box 72 is used to drive the pneumatic three-jaw chuck 73. At the same time, a tool mounting mechanism 8 is provided on each of the two horizontal bases 12, and the tool mounting mechanism 8 is located between the pneumatic three-jaw chuck 73 and the longitudinal slide 2. The tool mounting mechanism 8 includes a tool holder 81, a tool handle 82 and a tool 84. The tool holder 81 is arranged above the horizontal slide 71 for rotation, and the tool holder 81 can be raised and lowered relative to the horizontal slide 71. Two tool handles 82 are provided on the tool holder 81, and the two tool handles 82 form a "cross" structure. The two tool handles 82 are respectively arranged at the upper and lower ends of the tool holder 81. The tool handle 82 is arranged in the tool holder 81 through a bearing for rotation, and both ends of the tool handle 82 extend from the surface of the tool holder 81, and tools 84 are installed on both ends of the tool handle 82. When in use, different types or models of tools 84 can be installed on the two tool holders 82 according to actual needs. After the butterfly plate 51 or the valve body 52 is pressed and fixed, the butterfly plate 51 or the valve body 52 is moved to the processing station through the longitudinal slide 2 for processing. During the process, the appropriate tool 84 is directed toward the butterfly plate 51 or the valve body 52 by the rotation and lifting of the tool holder 81 according to the processing procedure. After the tool 84 is adjusted, the spindle box 72 is moved to make the pneumatic three-jaw chuck 73 close to the tool holder 82 and clamp it, and then the pneumatic three-jaw chuck 73, the tool holder 82 and the tool 84 are driven to rotate by the spindle box 72, and then the transverse slide 71 is moved to make the tool 84 close to the butterfly plate 51 or the valve body 52, and the initial shaft hole 53 on the butterfly plate 51 or the valve body 52 is rough-drilled, fine-drilled, punched hexagonal holes, etc. The structures at both ends of the tool holder 82 can be a spinning tool holder structure, which is convenient for the disassembly and replacement of the tool 84.

[0057] As attached Figures 12 to 18 as well as Fig.21As shown, the rotation and lifting of the tool holder 81 are driven by the tool switching mechanism 9, and a tool switching mechanism 9 is provided under the tool holder 81. The tool switching mechanism 9 includes a connecting rod 91, a rotating disk 92, a fixed disk 93, a guide frame 95 and a threaded sleeve 96. A fixed disk 93 is provided on the upper surface of the transverse slide 71, and a rotating disk 92 is provided on the outer side of the fixed disk 93. The rotating disk 92 is sleeved on the outer side of the fixed disk 93 for rotation. Specifically, the rotating disk 92 is a pulley structure, and the rotating disk 92 is connected to the main pulley 922 through a belt 921. The main pulley 922 is driven by a rotating motor 94 fixed to the transverse slide 71, and the upper surface of the rotating disk 92 is connected to the bottom surface of the tool holder 81 through a number of connecting rods 91. When in use, the rotating disk 92 is driven to rotate by the rotating motor 94, and the rotating disk 92 drives the tool holder 81 to rotate through the connecting rod 91, so that different tools 84 on the tool holder 81 can face the butterfly plate 51 or the valve body 52 on the processing station, thereby completing the switching of the tool 84.

[0058] Among them, as attached Figures 13 to 18 As shown, the connecting rod 91 is a telescopic rod, which includes an inner rod 912 and a rod sleeve 911 that slides on the outside of the inner rod 912. The top of the rod sleeve 911 is connected to the bottom surface of the tool holder 81, and the bottom end of the inner rod 912 is connected to the upper surface of the turntable 92. At the same time, a guide frame 95 is provided on the fixed plate 93, and the guide frame 95 is sleeved on the outside of the threaded sleeve 96. The top of the threaded sleeve 96 is connected to the bottom surface of the tool holder 81 through a bearing. A threaded rod 97 is provided in the threaded sleeve 96, and the threaded rod 97 and the threaded sleeve 96 are threadedly connected. A through hole 99 is provided on the fixed plate 93, and the through hole 99 extends to the bottom surface of the horizontal slide 71. The threaded rod 97 penetrates downward through the through hole 99 and is connected to the driven gear 971. A lifting motor 98 for driving the driving gear 972 to rotate is provided on the horizontal slide 71, and the driving gear 972 is meshed with the driven gear 971. When in use, the threaded rod 97 is driven to rotate by the lifting motor 98, and the threaded sleeve 96 drives the tool holder 81 to rise and fall under the action of the threaded rod 97, so that the switched tool 84 can be aligned with the pneumatic three-jaw chuck 73 for use. During the process, since the connecting rod 91 is a telescopic rod, it will not affect the lifting of the tool holder 81. In addition, the outer surface of the threaded sleeve 96 is provided with an inwardly concave slide groove, and the inner wall of the guide frame 95 is provided with a protruding slider. When the threaded sleeve 96 is set in the guide frame 95 and lifted, the slider is located in the slide groove and slides. The outer wall of the slider plays a limiting and guiding role on the inner wall of the slide groove, so that the threaded sleeve 96 can smoothly drive the tool holder 81 to rise and fall.

[0059] It is worth mentioning that Figure 4As shown, cooling water is needed when processing the butterfly plate 51 or the valve body 52. ​​At this time, the bottom of the installation groove 21 can be tilted toward the two sides of the two transverse bases 12, and the tilting direction is from the longitudinal base 11 to the transverse base 12, and tilted downward, so as to drain the cooling water flowing into the longitudinal slide 2, and avoid the positioning piston cylinder 35 and the pressing piston cylinder 44 from being soaked in water for a long time and causing damage. In addition, baffles 22 can be set at the top of the notches on both sides of the installation groove 21. The baffles 22 are hinged to the side of the longitudinal slide 2, and the height of the baffles 22 is less than the height of the installation groove 21. On the one hand, the bottom of the installation groove 21 can be exposed, so that the accumulated water in the installation groove 21 can flow away in time, and on the other hand, the impact of cooling water on the positioning piston cylinder 35 and the pressing piston cylinder 44 can be reduced.

[0060] In summary, during processing, the present invention positions the butterfly plate 51 or the valve body 52 by synchronously telescoping the positioning block 34, then moves the butterfly plate 51 or the valve body 52 to the calibration station, uses the telescopic push rod 62 to align the center, completes the calibration, and then lowers the truss 41 until the clamping plate 42 is pressed against the upper surface of the butterfly plate 51 or the valve body 52 to complete the fixing of the butterfly plate 51 or the valve body 52, and then moves the butterfly plate 51 or the valve body 52 to the processing station, and then rotates the tool holder 81 and Lift and lower, so that different tools 84 on the tool holder 81 can be aligned with the pneumatic three-jaw chuck 73, then move the spindle box 72, so that the pneumatic three-jaw chuck 73 is close to the tool handle 82 and clamped and fixed, finally drive the pneumatic three-jaw chuck 73, the tool handle 82 and the tool 84 to rotate through the spindle box 72, and move the transverse slide 71 at the same time, so that the tool 84 is close to the butterfly plate 51 or the valve body 52, and the initial shaft hole 53 on the butterfly plate 51 or the valve body 52 is rough-drilled, fine-drilled, etc. The positioning, calibration, fixing and processing of the butterfly plate 51 and the valve body 52 in the present invention are all automated, which reduces labor intensity and greatly improves processing efficiency. At the same time, the present invention is provided with a processing mechanism 7, a tool installation mechanism 8 and a tool switching mechanism 9 at both ends of the butterfly plate 51 and the valve body 52, so that both ends can be processed at the same time, further improving processing efficiency.

[0061] In addition, the movement of the longitudinal slide 2, the transverse slide 71 and the main shaft box 72 is driven by a screw mechanism. Specifically, the longitudinal base 11, the transverse base 12 and the transverse slide 71 are all provided with screws installed through bearings, and the screws are driven by screw motors provided on the longitudinal base 11, the transverse base 12 and the transverse slide 71, respectively. The bottom surfaces of the longitudinal slide 2, the transverse slide 71 and the main shaft box 72 are all provided with screw slides, and the screw slides on the longitudinal slide 2, the transverse slide 71 and the main shaft box 72 are respectively threadedly connected with the screws on the longitudinal base 11, the transverse base 12 and the transverse slide 71. When in use, the screw motor drives the screw to rotate, so that the longitudinal slide 2, the transverse slide 71 and the main shaft box 72 move under the drive of the screw slide. In the present invention, the movement of the positioning block 34, the push rod 62, the clamping plate 42, the longitudinal slide 2, the transverse slide 71 and the spindle box 72, the rotation and lifting of the tool holder 81, and the use of the pneumatic three-jaw chuck 73 are all controlled by a control box arranged on the frame 1. Specifically, a controller is arranged in the control box, and the positioning piston cylinder 35, the clamping piston cylinder 44, the electric push rod 61, the screw motor, the lifting motor 98, the rotating motor 94, and the pneumatic three-jaw chuck 73 are all electrically connected to the controller, and the equipment is controlled to process the butterfly plate 51 or the valve body 52 through a program compiled in the controller.

[0062] A processing step of an automated butterfly valve processing device is characterized by being performed in the following steps:

[0063] Processing of butterfly plate 51:

[0064] In the first step, the push member 32 is lifted or lowered. During the process, the push member 32 drives the positioning block 34 to move through the connecting arm 33. Since the guide hole 311 guides the transverse guide rod 341, the positioning block 34 can only be located outside the fixed column 31 and extend and retract synchronously.

[0065] The second step is to install the butterfly plate 51 between the plurality of positioning blocks 34. At this time, the butterfly plate 51 can be just placed in the space surrounded by the positioning grooves 342 on the plurality of positioning blocks 34, which plays a positioning role for the butterfly plate 51. At the same time, the convex strips 511 on the butterfly plate 51 are placed in the gaps between the adjacent positioning blocks 34 to avoid affecting the placement of the butterfly plate 51.

[0066] The third step is to move the butterfly plate 51 to the calibration position through the longitudinal slide 2;

[0067] The fourth step is to drive the push rod 62 to extend outward through the electric push rod 61, so that the conical tip of the push rod 62 is inserted into the initial shaft hole 53 of the butterfly plate 51 and aligned with the center. During the process, the butterfly plate 51 rotates slightly to complete the calibration. After the calibration, it can be ensured that the initial shaft hole 53 on the butterfly plate 51 will not be skewed when it is subsequently reprocessed, thereby ensuring the processing quality;

[0068] Step 5: lower the truss 41 until the pressing plate 42 is pressed against the upper surface of the butterfly plate 51, and the butterfly plate 51 is pressed and fixed on the positioning block 34;

[0069] Step 6: Move the butterfly plate 51 to the processing station via the longitudinal slide 2;

[0070] Step 7: Rotate the turntable 92 according to the processing steps. The turntable 92 drives the tool holder 81 to rotate through the connecting rod 91, so that different tools 84 on the tool holder 81 can face the butterfly plate 51 on the processing station, and the tool 84 is switched;

[0071] Step 8: The tool holder 81 is driven to rise and fall by the threaded sleeve 96 so that the switched tool 84 can be aligned with the pneumatic three-jaw chuck 73 for use. During the process, since the connecting rod 91 is a telescopic rod, the rise and fall of the tool holder 81 will not be affected;

[0072] Step 9, move the spindle box 72 to make the pneumatic three-jaw chuck 73 close to the tool handle 82 and clamp it;

[0073] The tenth step is to drive the pneumatic three-jaw chuck 73, the tool handle 82 and the tool 84 to rotate through the spindle box 72, and at the same time move the transverse slide 71 to make the tool 84 close to the butterfly plate 51, and perform rough drilling, fine drilling and other reprocessing on the initial shaft hole 53 on the butterfly plate 51.

[0074] Processing of valve body 52:

[0075] In the first step, the push member 32 is lifted or lowered. During the process, the push member 32 drives the positioning block 34 to move through the connecting arm 33. Since the guide hole 311 guides the transverse guide rod 341, the positioning block 34 can only be located outside the fixed column 31 and extend and retract synchronously.

[0076] The second step is to place the valve body 52 on the upper surface of the longitudinal slide 2. At this time, the valve body 52 can be sleeved on the outside of the positioning block 34, and the outer surfaces of the positioning blocks 34 can contact the inner wall of the valve body 52, which plays a positioning role for the valve body 52.

[0077] The third step is to move the valve body 52 to the calibration position via the longitudinal slide 2;

[0078] Step 4: The electric push rod 61 drives the push rod 62 to extend outward, so that the conical tip of the push rod 62 is inserted into the initial shaft hole 53 of the valve body 52 and aligned with the center. During the process, the valve body 52 rotates slightly to complete the calibration. After the calibration, it can be ensured that the initial shaft hole 53 on the valve body 52 will not be skewed when it is re-processed later, thereby ensuring the processing quality;

[0079] In the fifth step, the truss 41 is lowered until the clamping plate 42 clamps and fixes the valve body 52 on the longitudinal slide 2 , and the remaining processing steps of the valve body 52 are consistent with the processing steps of the butterfly plate 51 .

[0080] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
