Description

Technical Field

[0001] This application relates to the technical field of gas transmission, and particularly to a device for automatically drilling holes in PE valve parts. Background Art

[0002] At present, polyethylene (PE) pipes have more performance advantages and price advantages than pipes of other materials and are widely used in the gas industry. As an indispensable pipe control element in PE pipes, PE ball valves are receiving more and more use and attention.

[0003] The opening and closing of existing PE ball valves are controlled by an operating cap with a square head. To ensure its stable installation, a mounting hole needs to be drilled horizontally on it. Existing operating caps come in different sizes, and in some cases, the mounting hole needs to be drilled on an arc surface. Since a slender drill bit is used for drilling, manual drilling with a pistol drill often causes deviation, affecting the installation quality, with low efficiency, and requires connection to a power source, posing a risk of electric shock.

[0077] As Figure 2 shown, the starting component 14 is fixedly installed on the base plate 1 near the position of the cylinder 23. Figure 12 Yes Figure 4 Schematic perspective view of the starting component 14 of the automatic reciprocating motion component shown. Refer to Figure 12 , the starting component 14 includes: a valve mounting seat 141, a start button 142, a positioning pin 146, a guide pin 143, a locking pin 148 and a small connecting rod 144.

[0078] The valve mounting seat 141 is fixedly installed on the base plate 1 by bolts on one side of the central axis of the base plate 1. Figure 18 Yes Figure 13 Schematic diagram of the structure of the valve mounting seat 141 of the starting component 14 shown. Refer to Figure 18The valve mounting seat 141 is a Z-shaped structure, having a fixed end 1411 at the bottom, a valve portion 1412 in the middle, and a start end 1413 at the top. The fixed end 1411 is a horizontal plane with a light hole thereon for mounting and fixing on the base plate 1; the valve portion 1412 is a vertical plane with a threaded hole that passes through from front to back thereon for mounting a manual mechanical directional valve 15; the start end 1413 of the valve mounting seat 141 is a cubic structure, and the start end 1 A vertical light hole 1414 is opened from top to bottom at the center of the starter end 1413, and the side of the starter end 1413 corresponding to the positioning seat 3 is opened from outside to inside with a first threaded hole 1415 and a horizontal light hole 1416 respectively perpendicular to and through the vertical light hole 1414, and the side of the starter end 1413 corresponding to the cylinder 23 is opened with a through light hole 1417 perpendicular to the vertical light hole 1414 and through the starter end 1413. The through light hole 1417 is parallel to the horizontal light hole 1416, and the through light hole 1417 is perpendicular to the vertical light hole 1414 but does not penetrate.

[0079] Figure 13 yes Figure 4 The internal structure diagram of the starting assembly 14 in the automatic reciprocating motion component is shown. Figure 13 The start button 142 is provided with a first compression spring 147 and inserted into the vertical light hole 1414, and the part of the start button 142 inserted into the vertical light hole 1414 has a limit groove 1421 and a self-locking groove 1422 respectively; the positioning pin 146 extends from the first threaded hole 1415 into the start end 1413 and its end is inserted into the limit groove 1421 to prevent the start button 142 from slipping out of the start end 1413 upward under the action of the first compression spring 147; the guide pin 143 is provided with a second compression spring 149 and inserted from right to left into the through light hole 1417; the locking pin 148 extends from the horizontal light hole 1416 into the start end 1413 and its end is inserted into the self-locking groove 1422; the small connecting rod 144 is provided with two side-by-side through holes for inserting and locking the ends of the guide pin 143 and the locking pin 148.

[0080] Figure 14 yes Figure 13 The schematic diagram of the structure of the start button 142 of the start component 14 is shown. Figure 14, the start button 142 is basically a cylindrical structure with a disc at its upper end for finger pressing. An adjacent annular limit groove 1421 and a self-locking groove 1422 are formed at the lower end of the start button 142. The limit groove 1421 is used to prevent the start button 142 from being ejected by the first compression spring 147 after the positioning pin 146 extends into it. The self-locking groove 1422 is used for the insertion of the locking pin 148, which can realize the self-locking function of the start button 142, so that the start button 142 cannot rise under the action of the first compression spring 147 after the hand is released.

[0081] Figure 15 Yes Figure 13 Schematic structural diagram of the small connecting rod 144 of the start assembly 14 shown. Refer to Figure 15 , the small connecting rod 144 is a long strip structure, with a threaded hole and a smooth hole formed respectively. The two holes are parallel to each other and perpendicular to the strip plane. Figure 16 Yes Figure 13 Schematic structural diagram of the guide pin 143 of the start assembly 14 shown. Refer to Figure 16 , the guide pin 143 is basically divided into three sections. The right end is a thick cylinder, the middle is a slender cylinder, and the left end is the thinnest cylinder with external threads. After the guide pin 143 extends into the through hole 1417 of the start end 1413, it is fixedly connected to the threaded hole of the small connecting rod 144 by threads on its left side. Figure 17 Yes Figure 13 Schematic structural diagram of the locking pin 148 of the start assembly 14 shown.

[0082] As Figure 2As shown in the figure, the manual mechanical direction valve 15 is fixedly installed on the valve part 1412 of the valve mounting seat 141 by bolts. The manual mechanical direction valve 15 is connected to the cylinder 23 through a hose and is used to control the extension and retraction of the piston rod of the cylinder 23. When the start button 142 is pressed, the guide pin 143 moves to the right under the action of the second compression spring 149, driving the small connecting rod 144 and the locking pin 148 to move to the right. The locking pin 148 is inserted into the self-locking groove 1422 of the start button 142, so that the start button 142 cannot rise under the action of the first compression spring 147 after the hand is released. The start button 142 presses the manual mechanical direction valve 15, thereby controlling the cylinder 23 to drive the square linear bearing 9 to slide leftward on the guide rod 5, and then driving the pneumatic drill 13 to drill holes. When the adjustment bolt 1022 on the automatic return connecting rod 10 pushes the guide pin 143 to move leftward during the leftward movement, the guide pin 143 drives the small connecting rod 144 and the locking pin 148 to move leftward. The locking pin 148 exits the self-locking groove 1422 of the start button 142, and the start button 142 rises under the action of the first compression spring 147 and no longer presses the manual mechanical direction valve 15, so that the cylinder 23 drives the square linear bearing 9 and the pneumatic drill 13 to move rightward and retract until the retraction is in place to complete the drilling.

[0083] Figure 19 is Figure 4 The structural schematic diagram of the automatic return connecting rod 10 of the automatic reciprocating moving part shown in the figure. Refer to Figure 19 As shown in the figure, the automatic return connecting rod 10 includes a connecting rod main body 101 and a long rod 102 connected thereto.

An L-shaped hook 1021 extends from the free end of the long rod 102. A threaded hole parallel to the direction of the long rod 102 is opened on the L-shaped hook 1021, and an adjustment bolt 1022 corresponding to the valve mounting seat 141 is installed thereon.

[0084] As Figure 2 As shown in the figure, a circular buffer pad 20 is sleeved on the guide rod 5 between the square linear bearing 9 and the guide rod seat 4, and the buffer pad 20 fits against the inner side of the guide rod seat 4.

[0085] As Figure 2 As shown in the figure, the pneumatic drill component is used to drill holes in the operation cap 24 of the product to be processed. Figure 3 is Figure 2 The structural schematic diagram of the pneumatic drill component of the device for automatically drilling holes in PE valve parts shown in the figure. Refer to Figure 3, the pneumatic drill component includes: a pneumatic drill 13, a drill bit 8, a pneumatic drill fixing cover 12, a valve support 18, a mechanical on-off valve 19, and an on-off valve pressing rod 11. The pneumatic drill 13 is horizontally installed on the pneumatic drill mounting seat 17 and is clamped and fixed by the pneumatic drill fixing cover 12; one end of the drill bit 8 is clamped and installed at the rotation center of the pneumatic drill 13 and is parallel to the central axis of the base plate 1, and the other end is a free end and can extend into the guide sleeve 7.

[0086] Figure 11 is Figure 2 The structural schematic diagram of the pneumatic drill fixing cover 12 of the automatic punching device for the PE valve parts shown. See Figure 11 , the pneumatic drill fixing cover 12 has a semi-circular notch, which cooperates with the pneumatic drill mounting seat 17 for installing and fixing the pneumatic drill 13.

[0087] Figure 21 is Figure 3 The structural schematic diagram of the pneumatic drill 13 of the pneumatic drill component shown. See Figure 21 , on the left side of the pneumatic drill 13 is a three-jaw clamping part for clamping the drill bit 8, and on the right side is for connecting the air nozzle. The pneumatic drill fixing cover 12 and the pneumatic drill mounting seat 17 are fixedly connected by bolts, and the pneumatic drill 13 is horizontally installed on the pneumatic drill mounting seat 17 by being clamped and fixed through the circular hole formed by the combination of the pneumatic drill fixing cover 12 and the pneumatic drill mounting seat 17. The drill bit 8 is parallel to the piston rod of the air cylinder 23 at the rotation center of the pneumatic drill 13.

[0088] As Figure 3 shown, the valve support 18 is fixedly installed on the base plate 1 near the air cylinder 23 by bolts and is arranged on both sides of the piston rod of the air cylinder 23 with the starting component 14; the mechanical on-off valve 19 is fixedly installed on the valve support 18 by bolts. The mechanical on-off valve 19 is connected to the pneumatic drill 13 through a hose, and the roller 191 of the mechanical on-off valve 19 is set upward; the on-off valve pressing rod 11 is fixedly installed on the square linear bearing 9 on the same side as the mechanical on-off valve 19 by bolts, and the slender rod 111 extending from the on-off valve pressing rod 11 presses above the roller 191 of the mechanical on-off valve 19.

[0089] Figure 22 is Figure 3 The structural schematic diagram of the valve support 18 of the pneumatic drill component shown. See Figure 18 , the valve support 18 is a vertical flat plate with horizontal threaded holes for installing the mechanical on-off valve 19, and there are two horizontal small flat plates on both sides with through holes from top to bottom for fixing to the base plate 1.

[0090] Figure 20 is Figure 3 The structural schematic diagram of the on-off valve pressing rod 11 of the pneumatic drill assembly shown. See Figure 20, on the left side of the on-off valve push rod 11 is a square structure with a grooved countersunk hole drilled from top to bottom. A slender rod 111 extends to the right from the upper part of the square structure. A section at the tail of the side of the extended slender rod 111 in contact with the roller 191 is widened downward, and there is an arc or bevel transition between the widened part and the non-widened part. When the start button 142 is pressed to make the automatic reciprocating moving part move to the left, the square linear bearing 9 drives the on-off valve push rod 11 to move to the left, thereby pressing down the roller 191 of the mechanical on-off valve 19, connecting the air passage to make the pneumatic drill 13 drive the drill bit 8 to rotate and perform the drilling and cutting action. When the automatic reciprocating moving part returns to the in-place position, the on-off valve push rod 11 no longer presses down the roller 191 of the mechanical on-off valve 19, thereby cutting off the air passage of the mechanical on-off valve 19 and the pneumatic drill 13 stops rotating.

[0091] As Figure 2 shown, the guiding component is installed on the base plate 1 and is located adjacent to the positioning seat 3 for guiding the pneumatic drill component. The guiding component includes: a guide sleeve mounting seat 6 and a guide sleeve 7. Figure 23 is Figure 2 a schematic structural view of the guide sleeve mounting seat 6 of the automatic punching device for PE valve parts shown. Refer to Figure 23 , the guide sleeve mounting seat 6 is in a "7" shape. A through hole is drilled downward in its horizontal part for fixing with the base plate 1; a horizontal through hole and a horizontal threaded hole are drilled in its vertical part for installing the guide sleeve 7; the guide sleeve mounting seat 6 is installed at the central axis position of the base plate 1 and is adjacent to the positioning seat 3; Figure 24 is Figure 2 a schematic structural view of the guide sleeve 7 of the automatic punching device for PE valve parts shown. Refer to Figure 24 , the guide sleeve 7 is installed at the top of the guide sleeve mounting seat 6. The guide sleeve 7 is a stepped cylindrical structure with a through hole drilled in the center. A local plane is opened on the cylindrical surface of the large head for fitting and installing with the vertical part of the guide sleeve mounting seat 6.

[0092] Figure 1 is an application schematic view of the automatic punching device for PE valve parts according to an embodiment of the present application. As Figure 1 shown, a protective cover 22 is installed above the pneumatic drill component and the automatic reciprocating moving component on the base plate 1 for safety protection. The protective cover 22 is a U-shaped thin plate structure, and a square hole is opened in its upper part for the start button 142 to protrude. As Figure 1 shown, the pressure regulating valve 21 is connected to the external air source for adjusting the air pressure; the pressure regulating valve 21 is installed on the protective cover 22, and the air inlets of the mechanical on-off valve 19 and the manual mechanical direction valve 15 are respectively connected to the pressure regulating valve 21 through flexible hoses.

[0093] The specific implementation process is as follows: According to the model of the operating cap 24, quickly replace the positioning seat 3. Connect the air source to the pressure regulating valve 21, adjust the pressure of the pressure regulating valve 21, install the operating cap 24 on the positioning seat 3. After pressing the start button 142, the guide pin 143 moves to the right under the action of the second compression spring 149, driving the small connecting rod 144 and the locking pin 148 to move to the right. The locking pin 148 is inserted into the self-locking groove 1422 of the start button 142, so that the start button 142 cannot rise under the action of the first compression spring 147 after releasing the hand. The start button 142 presses the manual mechanical direction valve 15, thereby controlling the air cylinder 23 to drive the square linear bearing 9 to slide leftward on the guide rod 5, thereby driving the pneumatic drill 13 to drill holes. At the same time, the square linear bearing 9 drives the on-off valve pressing rod 11 to move leftward, thereby pressing down the roller 191 of the mechanical on-off valve 19, thereby connecting the air path so that the pneumatic drill 13 drives the drill bit 8 to rotate. The drill bit 8 is guided by the guide sleeve 7 to drill holes in the operating cap, performing drilling and cutting actions; when moving leftward until the adjusting bolt 1022 on the automatic return connecting rod 10 pushes the guide pin 143 to move leftward, the guide pin 143 drives the small connecting rod 144 and the locking pin 148 to move leftward. The locking pin 148 exits the self-locking groove 1422 of the start button 142, and the start button 142 rises under the action of the first compression spring 147, no longer pressing the manual mechanical direction valve 15, thereby causing the air cylinder 23 to drive the square linear bearing 9 and the pneumatic drill 13 to move rightward and retract. When the retraction is in place, the on-off valve pressing rod 11 no longer presses down the roller 191 of the mechanical on-off valve 19, so that the mechanical on-off valve 19 cuts off the air path with the pneumatic drill 13, and the pneumatic drill 13 stops rotating. Remove the operating cap to complete automatic drilling. By replacing different positioning seats 3, operating caps of different models can be processed.
