Description

Technical Field

[0001] This utility model relates to the field of pneumatic diaphragm valve double-layer diaphragm production technology, specifically a pneumatic diaphragm valve double-layer diaphragm positioning drilling device. Background Technology

[0002] A double-layer diaphragm is used as a sensitive elastic element in the valve core of a diaphragm valve. A diaphragm valve contains a double-layer diaphragm within the valve body and cover, and its closing element is a compression device connected to the diaphragm. The valve seat can be weir-shaped or a straight-through pipe wall. The advantage of a diaphragm valve is that its operating mechanism is isolated from the media passage. As the heart of the valve, the diaphragm's hygienic quality is strictly monitored by health authorities.

[0003] Reference patent publication number "CN107972114A" discloses a positioning drilling device for a double-layer diaphragm production equipment for diaphragm valves, which includes a positioning fixture, a rotating mechanism for driving the positioning fixture to rotate intermittently, and a drilling mechanism disposed next to the rotating mechanism. The rotating mechanism includes a horizontal turntable and a driving component for driving the turntable to rotate intermittently horizontally, and the positioning fixture is disposed on the turntable.

[0004] This patent avoids the situation where the drilling positions of the soft diaphragm and hard diaphragm are inconsistent. When drilling the positioning holes of the double-layer diaphragm of the pneumatic diaphragm valve, feeding is required. Most existing feeding methods involve conveying the material through a conveying mechanism and feeding it into the drilling device through a corresponding robotic arm. This feeding method results in a large overall footprint of the positioning drilling device and reduced work efficiency. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 The pneumatic diaphragm valve double-layer diaphragm positioning drilling device provides two technical solutions:

[0025] The first embodiment includes a support box 1 and a drilling assembly 2. A rapid feeding mechanism is provided on the upper part of the support box 1. A pneumatic diaphragm valve double-layer diaphragm stacking box 5 is fixedly connected to the right side of the support box 1. The pneumatic diaphragm valve double-layer diaphragm stacking box 5 is located above the feeding tray 32, and the bottom of the pneumatic diaphragm valve double-layer diaphragm stacking box 5 is flush with the top of the feeding tray 32. A chip removal plate 6 is fixedly connected to the top of the inner wall of the support box 1, and the chip removal plate 6 penetrates the support box 1 and extends to the left side of the support box 1. A through hole is opened on the top of the support box 1, and the position of the through hole corresponds to that of the chip removal plate 6. The rapid feeding mechanism includes:

[0026] Intermittent feeding assembly 3 is used for continuous feeding of the double-layer diaphragm of the pneumatic diaphragm valve. The intermittent feeding assembly 3 includes a main shaft 31, which is rotatably connected to the right side of the top of the support box 1. A feeding plate 32 is fixedly connected to one end of the main shaft 31 above the support box 1. Four placement slots 33 for placing the double-layer diaphragm of the pneumatic diaphragm valve are evenly spaced on the top of the feeding plate 32. Multiple hollow slots 34 are evenly spaced on the bottom of the inner wall of the placement slots 33. A driven plate 35 is fixedly connected to one end of the main shaft 31 that passes through the support box 1 and extends into the interior of the support box 1. Four guide slots 36 are evenly spaced along the circumference on the surface of the driven plate 35. A support plate 37 is fixedly connected to the back of the inner wall of the support box 1. A drive motor 38 is fixedly connected to the top of the support plate 37. A disc 39 is fixedly connected to the output end of the drive motor 38. A guide rod 310 for cooperating with the guide slots 36 is fixedly connected to the top of the disc 39.

[0027] When drilling for positioning of the double-layer diaphragm of the pneumatic diaphragm valve, the intermittent feeding assembly 3 is used to feed the double-layer diaphragm of the pneumatic diaphragm valve. The intermittent feeding assembly 3 has a compact structure, small footprint, and high continuity during feeding, which improves the practicality of the device.

[0028] The second embodiment differs from the first embodiment in that: the positioning component 4 is located on the left side of the intermittent feeding component 3 and is used to press and position the double-layer diaphragm of the pneumatic diaphragm valve in the hollow groove 34. The positioning component 4 includes a cylinder 41, which is fixedly connected to the left side of the top of the support box 1. An arc plate 42 is fixedly connected to the telescopic end of the cylinder 41. An infrared transmitter 43 is fixedly connected to the right side of the cylinder 41. Four infrared receivers 44 that cooperate with the infrared transmitters 43 are fixedly connected at equal intervals at the bottom of the feeding tray 32. The positions of the four infrared receivers 44 correspond to the positions of the four hollow grooves 34.

[0029] When the feeding tray 32 rotates, the cylinder 41 works through the cooperation of the infrared generator 43 and the infrared receiver 44 to position the double-layer diaphragm of the pneumatic diaphragm valve in the placement slot 33, and at the same time, the drilling assembly 2 starts to work, which improves the automation level of the device.

[0030] In use, multiple pneumatic diaphragm valve double-layer diaphragms are stacked in the pneumatic diaphragm valve double-layer diaphragm valve stacking box 5. The bottom pneumatic diaphragm valve double-layer diaphragm valve enters the hollow groove 34. The drive motor 38 is started to make the disc 39 rotate continuously. The rotation of the disc 39 drives the guide rod 310 to rotate. With the cooperation of the guide rod 310 and the guide groove 36, the feeding disc 32 rotates intermittently. When the infrared receivers 44 and 45 are aligned, the infrared receiver 44 receives the infrared laser emitted by 45. Then the cylinder 41 starts to work and presses and positions the pneumatic diaphragm valve double-layer diaphragm valve through the arc plate 42. At the same time, the drilling assembly 2 starts to drill holes in the pneumatic diaphragm valve double-layer diaphragm valve. This process is repeated. The debris generated by drilling enters the chip removal plate 6 through the hollow groove 34 and slides out.
