[0002] A regulating valve is a valve used to adjust process parameters such as medium flow, pressure, temperature, liquid level, etc. in the field of industrial automation process control. It automatically adjusts the valve opening according to the control signal in the automation system, thereby achieving the regulation of medium flow, pressure, temperature and liquid level.

[0003] Reference Figure 1 The valve flap 40 of the regulating valve is provided with a first bore hole 401 and a second bore hole 402. During the processing of the valve flap 40, the valve flap is first turned to form a shape, and then the first bore hole 401 and the second bore hole 402 are processed. Since the diameters of the first bore hole and the second bore hole are different, in the actual drilling operation, the first bore hole is first processed by a drilling machine, and then the valve flap is transferred to another drilling machine for processing the second bore hole, which is troublesome and requires manual transfer, and is not convenient.

At this time, the first drill rod is located above the valve disc, and the mounting plate descends, which drives the first drill rod to descend. The first drill rod drills the valve disc to form a first borehole. After the first borehole is formed, the rotating plate rotates to rotate the second drill rod to the position of the first drill rod. Because the first drill rod and the second drill rod are located on the same rotation trajectory, when the rotating plate rotates, the second drill rod can be rotated to the first drill rod. Then the mounting plate descends, and the second drill rod drills the valve disc to form a second borehole. The drilling device of the present application can realize the forming of the first borehole and the second borehole without the need to transport the valve disc, which is more convenient and reduces the labor intensity of manual labor.

[0042] The valve disc is placed on the base 1 and located between the three clamping plates 21. The three clamping plates 21 slide synchronously to clamp and fix the valve disc and center the valve disc. Then the mounting plate 3 descends, driving the rotation to descend. The first drill rod 41 works first to form the first drill rod 41. After forming, the mounting plate 3 is reset, the rotating plate 4 rotates 180 degrees, and the second drill rod 42 moves to the top of the valve disc. The mounting plate 3 then drives the second drill rod 42 to descend to form the second borehole. The drilling device of the present application can be used to form the first borehole and the second borehole at one time. The valve disc does not need to be transported in the middle, which is more convenient, helps to reduce the labor intensity, and helps to improve processing efficiency.

[0043] Reference Figure 2 , Figure 3 and Figure 4 , the three clamping plates 21 are distributed in a circular array, and three sliding grooves 12 are provided on the surface of the base 1 corresponding to the three clamping plates 21, and the clamping plates 21 are slidably connected in the corresponding sliding grooves 12. A mounting groove 13 is provided in the base 1, and the driving member is set as a driving disk 22. A rotating shaft 131 is connected to the mounting groove 13 in a vertical direction, and the driving disk 22 is coaxial with the rotating shaft 131. The rotating shaft 131 is driven to rotate by a rotating cylinder, which is not shown in the figure. Three connecting rods 221 are hinged on the driving disk 22, and the three connecting rods 221 correspond to the three clamping plates 21 one by one. The end of the connecting rod 221 away from the driving disk 22 is hinged to the corresponding clamping plate 21, wherein the hinge point between the connecting rod 221 and the driving disk 22 is eccentric to the center of the circle of the driving disk 22. The rotary cylinder drives the rotating shaft 131 to rotate, which drives the driving plate 22 to rotate, and the three connecting rods 221 move accordingly, and drive the three clamping plates 21 to slide synchronously, so as to clamp and fix the valve disc.

[0044] Reference Figure 2 , Figure 5 and Figure 6 The lower side of the mounting plate 3 is rotatably connected with a rotating sleeve 5, and a driving assembly 6 for driving the rotating sleeve 5 to rotate is arranged on the mounting plate 3; a linkage rod 7 is arranged inside the rotating sleeve 5, and a lifting groove 51 is provided on the inner wall of the rotating sleeve 5 in the vertical direction, and two lifting grooves 51 are arranged, and the two lifting grooves 51 are arranged opposite to each other, and two lifting blocks 71 are integrally formed on the linkage rod 7, and the two lifting blocks 71 correspond to the two lifting grooves 51 one by one, and the lifting blocks 71 are inserted into the corresponding lifting grooves 51, and the lifting blocks 71 and the lifting grooves 51 form a sliding fit in the vertical direction. Through the cooperation of the lifting blocks 71 and the lifting grooves 51, the coaxial rotation and lifting and sliding fit of the linkage rod 7 and the rotating sleeve 5 are realized, and the lower end of the linkage rod 7 passes through the rotating sleeve 5, and the lower end of the linkage rod 7 is in a smooth ball shape. The rotating sleeve 5 is located in the lifting slot 51 and is installed with a compression spring 52, which is vertically arranged and located on the upper side of the lifting block 71. One end of the compression spring 52 is connected to the lifting block 71, and the other end of the compression spring 52 is connected to the inner wall of the lifting slot 51. A sliding slot 72 is provided on the lower side wall of the linkage rod 7. Two sliding slots 72 are provided and are arranged opposite to each other. The linkage rod 7 is slidably provided with a locking block 73 in the sliding slot 72.

[0045] Reference Figure 2 , Figure 6 and Figure 7 The upper ends of the first drill rod 41 and the second drill rod 42 are coaxially fixed with a linkage disk 8, and the peripheral edge of the linkage disk 8 is formed with an inclined guide surface 81. The middle of the linkage disk 8 is provided with an avoidance groove 82 for avoiding the linkage rod 7, and the avoidance groove 82 is in a concave spherical shape. The edge of the linkage disk 8 located at the avoidance groove 82 is provided with two locking grooves 83, and the two locking grooves 83 correspond to the two locking blocks 73. When the linkage rod 7 enters the avoidance groove 82, the locking block 73 slides outward and plugs into the locking groove 83.

[0046] In the initial state, the lower end of the linkage rod 7 is located in the avoidance groove 82 of the linkage disk 8 of the first drill rod 41. When the driving motor 61 drives the rotating sleeve 5 to rotate, the locking block 73 slides outward and plugs into the locking groove 83. The cooperation of the locking block 73 and the locking groove 83 realizes the coaxial rotation cooperation of the linkage rod 7 and the first drill rod 41. The rotating sleeve 5 drives the first drill rod 41 to rotate through the linkage rod 7 to realize the forming of the first borehole. After the first drill rod 41 is formed, the first drill rod 41 is separated from the valve disc, and the rotating sleeve 5 stops rotating. At this time, the locking block 73 slides and engages with the locking block 73. The groove 83 disengages, the rotating plate 4 rotates, and the second drill rod 42 rotates to the position of the first drill rod 41. The lower end of the linkage rod 7 first contacts the guide surface 81 of the linkage disk 8, and the linkage rod 7 moves along the guide surface 81 of the linkage disk 8 to the upper surface of the linkage disk 8 until it enters the avoidance groove 82. The linkage rod 7 is lifted and lowered by the action of the compression spring 52. Then the driving assembly 6 drives the rotating sleeve 5 to rotate, and the locking block 73 enters the locking groove 83, realizing the coaxial rotation cooperation between the linkage rod 7 and the second drill rod 42. After that, the drilling operation can be carried out to form the second drill hole.

[0047] Reference Figure 5 and Figure 6 The mounting plate 3 is provided with a driving rod 9 for lifting and lowering. The driving rod 9 is vertically arranged and extends into the linkage rod 7. The lower end of the driving rod 9 is formed with a first wedge surface 91. The ends of the two locking blocks 73 that are close to each other are formed with a second wedge surface 731. When the driving rod 9 descends, the two locking blocks 73 can slide by the cooperation of the first wedge surface 91 and the second wedge surface 731. The linkage rod 7 is also provided with an annular groove 721 on the peripheral side of the slide groove 72. The peripheral side of the locking block 73 is integrally formed with an annular plate 732. The linkage rod 7 is provided with a return spring 74 in the annular groove 721. The length direction of the return spring 74 is consistent with the sliding direction of the locking block 73. One end of the return spring 74 is connected to the annular plate 732, and the other end of the return spring 74 is connected to the inner wall of the annular groove 721. The driving rod 9 descends, and the locking block 73 slides outward to cooperate with the locking groove 83. When the driving rod 9 rises, under the action of the reset spring 74, the locking block 73 is reset and disengaged from the locking groove 83.

[0048] A connecting rod 10 is provided on the mounting plate 3 for lifting. A plug-in slot 101 is provided at the lower end of the connecting rod 10 in the vertical direction. A plug-in rod 92 is integrally formed at the upper end of the driving rod 9. The plug-in rod 92 is plugged and slidably matched with the plug-in slot 101. A buffer spring 93 is sleeved on the peripheral side of the plug-in rod 92. One end of the buffer spring 93 is connected to the driving rod 9, and the other end of the buffer spring 93 is connected to the connecting rod 10. In practice, the following situations may occur:

[0049] 1) After the linkage rod 7 enters the avoidance groove 82, the locking block 73 slides outward, but the locking block 73 is not aligned with the locking groove 83, that is, the locking block 73 is misaligned with the locking groove 83, and the locking block 73 will abut against the inner wall of the avoidance groove 82, that is, the sliding of the locking block 73 is small, and the descending stroke of the connecting rod 10 remains unchanged, that is, at this time, the descending stroke of the driving rod 9 becomes smaller, and the buffer spring 93 is in a compressed state. When the rotating sleeve 5 rotates, the rotating sleeve 5 drives the linkage rod 7 to rotate, and the locking block 73 gradually aligns with the locking groove 83. When aligned, the buffer spring 93 quickly acts on the driving rod 9, and the driving rod 9 descends, driving the sliding block to slide outward and plug into the locking groove 83.

[0050] When the locking block 73 is in the locked state, the locking block 73 will be in the locked state, and the locking block 73 will be in the locked state when the locking block 73 is in the locked state.

[0051] That is, the structural design of the present application can automatically solve the above two situations when the rotating sleeve 5 rotates.

The center of curvature of the arc groove 301 is located at the center of the driving wheel 30. The bottom wall of the arc groove 301 is wedge-shaped, that is, the two ends of the arc groove 301 are the lowest end and the highest end respectively. The eccentric rod 361 extends into the arc groove 301 and slides with the arc groove 301. In the initial state, the eccentric rod 361 is located at the lowest end of the arc groove 301.

At the same time, the third sprocket 33 rotates, and the third sprocket 33 drives the first pulley 34 to rotate. The first pulley 34 drives the second pulley 36 to rotate through the belt 37. When the second pulley 36 rotates, the eccentric rod 361 slides in the arc groove 301 of the driving wheel 30, and slides from the lowest end of the arc groove 301 to the highest end. Then, the second pulley 36 drives the driving wheel 30 to rotate synchronously. When the eccentric rod 361 slides from the lowest end to the highest end of the arc groove 301, due to the height difference between the lowest end and the highest end, the driving wheel 30 will descend, and drive the connecting rod 10 to descend through the lifting plate 20, thereby realizing the sliding of the locking block 73. The sliding of the locking block 73 cooperates with the locking groove 83 to realize the coaxial rotation cooperation of the linkage rod 7 and the linkage disk 8, and then the drill rod can be driven to rotate. When the drilling is completed, the driving motor 61 stops rotating. At this time, the abutment spring 381 acts on the lifting plate 20, and the lifting plate 20 rises. The eccentric rod 361 will reset to the lowest end of the arc groove 301, and the driving rod 9 will also rise. The locking block 73 will retract into the linkage rod 7 under the action of the reset spring 74 and disengage from the locking groove 83.

[0056] The implementation principle of a drilling device for a regulating valve flap in the embodiment of the present application is as follows: the valve flap is placed on the base 1 and located between the three clamping plates 21, the driving plate 22 rotates, driving the three clamping plates 21 to slide toward each other, clamping and fixing the valve flap, and the driving motor 61 is started. At this time, the linkage rod 7 and the first drill rod 41 rotate coaxially, the rotating sleeve 5 rotates, and then the first drill rod 41 rotates, and the mounting plate 3 descends, and the first drilling hole of the valve flap can be formed. After forming, the mounting plate 3 rises, the driving motor 61 stops, the linkage rod 7 and the first drill rod 41 contact and rotate coaxially, the rotating plate 4 rotates, and the second drill rod 42 moves to the lower side of the linkage rod 7, and the driving motor 61 is started. At this time, the linkage rod 7 and the second drill rod 42 rotate coaxially, and the mounting plate 3 descends, and the second drilling hole of the valve flap can be formed. Through the drilling device of the present application, the first drilling hole and the second drilling hole can be formed at one time, which is faster and does not require the valve flap to be transported, reducing the labor intensity and improving the processing efficiency.
