Detailed implementation manners

[0031] The present invention will be specifically described below with reference to the drawings, as Figures 1 - 8As shown in the figure, a detection device for processing filter parts includes a workbench 1. Two slide rails 12 are arranged in parallel on the workbench 1. Two sliders 121 are slidably arranged on each slide rail 12. On the upper sides of the sliders 121 at the same end of the two slide rails 12, the same mounting plate 122 is bolted. A detection component 2 is fixedly connected to the mounting plate 122. The detection component 2 is connected to both ends of the filter tube to detect the sealing performance of the filter tube.

[0032] The lower side of the mounting plate 122 is bolted to the telescopic end of the driving module 13. The driving module 13 is a prior art. A servo motor drives a lead screw to drive the slider to move along the slide rail. It can accurately control the position and moving speed of the slider and lock the position of the slider. The driving module 13 is used to drive the mounting plate 122 and the detection component 2 on the mounting plate 122 to move, so as to connect the detection component 2 and the end of the filter tube and realize the sealing detection of the filter tube.

[0033] A support platform 11 is bolted in the middle of the workbench 1. A plurality of positioning blocks 111 are bolted to the support platform 11. A positioning groove 112 is arranged at the upper end of the positioning block 111. The positioning groove 112 is a symmetric V shape. Through the setting of the positioning groove 112, the filter tube can be automatically centered to realize the positioning of the filter tube. The positioning is simple and the work efficiency is high.

[0034] Further, referring to Figure 1 , three positioning blocks 111 are provided. The vertical planes where two of the positioning blocks 111 are located are parallel, and the vertical plane where the other positioning block 111 is located forms an acute angle with the vertical plane where the two parallel positioning blocks 111 are located. Since the planes where the three positioning blocks 111 are located are not parallel to each other, the filter tube can be positioned in multiple directions. The filter tube can be positioned only by placing it on the three positioning blocks 111, and the operation is simple, convenient and fast.

[0035] Further, referring to Figure 3 and Figure 5 , the detection component 2 includes a cylinder barrel 22. Two symmetrically arranged guide blocks 23 are fixedly sleeved on the outer side of the cylinder barrel 22. The two guide blocks 23 are bolted and fixedly connected to the outer side of the cylinder barrel 22. A U-shaped fixing seat 21 is bolted at the screwed part of the two guide blocks 23. The lower end of the U-shaped fixing seat 21 is inserted into the upper end of the mounting plate 122. The cylinder barrel 22 is fixedly connected to the mounting plate 122 through the U-shaped fixing seat 21. When the mounting plate 122 moves along the slide rail, the mounting plate 122 drives the cylinder barrel 22 to move.

[0036] A piston disk 229 is slidably arranged inside a cylinder barrel 22. A piston ring 2291 is sleeved outside the piston disk 229. The piston ring 2291 is used to achieve a sliding seal connection between the piston disk 229 and the cylinder barrel 22. A slide bar 227 is bolted to the side surface of the piston disk 229. The slide bar 227 is in the shape of a quadrangular prism. The slide bar 227 passes through a guide plate 228 bolted to the end of the cylinder barrel 22. A spring 2292 is arranged between the piston disk 229 and the guide plate 228. The piston disk 229 is pushed by the spring 2292 to extend into the cylinder barrel 22. The guide plate 228 is used to guide the movement of the slide bar 227 to prevent the slide bar 227 from being deflected. The guide plate 228 also limits the slide bar 227 to prevent the slide bar 227 from rotating.

[0037] Further, referring to Figure 4 and Figure 5 , tooth plates 2271 are fixedly installed on both the front and rear side surfaces of the slide bar 227. The two tooth plates 2271 are meshed and connected to a gear 35 on the side away from each other. The gear 35 is rotatably connected to a fixed ear plate 223. The fixed ear plate 223 is fixedly connected to the end of the cylinder barrel 22. The gear 35 is coaxially and fixedly connected to a turning bar 3. The turning bar 3 is in an L shape. A telescopic rod 31 is slidably inserted into the end of the turning bar 3 away from the gear 35. A clamping arc plate 312 is arranged at the other end of the telescopic rod 31. A locking assembly is arranged on the side surface of the turning bar 3 for locking the telescopic rod 31. The relative positioning between the telescopic rod 31 and the turning bar 3 can be achieved through the locking assembly to prevent the telescopic rod 31 from moving away from the turning bar 3. When the clamping arc plates 312 approach each other, they can be clamped behind the flange at the end of the filter pipe. Through the relative fixation of the clamping arc plate 312 and the flange, the relative fixation between the cylinder barrel 22 and the filter pipe is achieved to prevent the cylinder barrel 22 from detaching from the filter pipe during operation.

[0038] Further, referring to Figure 4 and Figure 8 , the locking assembly includes fixing plates 32 bolted to the side surfaces of the two turning bars 3 away from each other. There are two fixing plates 32 and they are symmetrically arranged. A clamping plate 33 is hinged to the top of the fixing plate 32. A leaf spring 34 is hinged to the top of the fixing plate 32. One end of the leaf spring 34 abuts against the side surface of the clamping plate 33 close to the fixing plate 32, and the other end abuts against the surface of the turning bar 3. Through the arrangement of the leaf spring 34, the leaf spring 34 presses the inner side of the clamping plate 33, so that the other end of the clamping plate 33 always has a tendency to move towards the turning bar 3, making the clamping plate 33 abut against the surface of the turning bar 3.

[0039] A plurality of card slots 311 are evenly distributed on the side surface of the telescopic rod 31 close to the locking assembly. There is a rectangular slot on the turning bar 3 between the card slots 311 and the clamping plate 33. The end of the clamping plate 33 away from the leaf spring 34 passes through the rectangular slot and abuts in the card slot 311. By clamping the clamping plate 33 in the card slot 311, the telescopic rod 31 is prevented from moving away from the turning bar 3, realizing the locking of the telescopic rod 31.

[0040] Furthermore, referring to Figure 3 and Figure 4 , driving grooves 2272 are symmetrically arranged on the upper and lower sides of the sliding rod 227. A sliding rod 232 is slidably connected in each driving groove 2272. One end of the sliding rod 232 away from the driving groove 2272 is connected to a push rod 231. The push rod 231 slidably penetrates through the guiding block 23. An extrusion arc block 233 is arranged at one end of the push rod 231 away from the sliding rod 232. During operation, when the detection assembly 2 moves towards the filter pipe, the extrusion arc block 233 abuts against the flange at the end of the filter pipe. The flange drives the extrusion arc block 233 to drive the sliding rod 232 to slide in the guiding block 23. The sliding rod 232 drives the push rod 231 to move away from the cylinder barrel 22. The push rod 231 abuts against the inner side of the driving groove 2272, driving the sliding rod 227 away from the cylinder barrel 22. The toothed plates 2271 on both sides of the sliding rod 227 drive the gear 35 to rotate, and the gear 35 drives the flipping rod 3 to move closer to and close to the filter pipe.

[0041] Furthermore, referring to Figure 5 , a positioning inclined surface 224 is arranged at one end of the cylinder barrel 22 away from the guiding plate 228. The positioning inclined surface 224 facilitates inserting the cylinder barrel 22 into the filter pipe, facilitating the docking of the filter pipe and the cylinder barrel 22. A retaining ring 226 is arranged at the end of the cylinder barrel 22 close to the positioning inclined surface 224. The diameter of the retaining ring 226 is larger than the inner hole diameter of the filter pipe. An airbag 225 is sleeved between the retaining ring 226 and the positioning inclined surface 224. The airbag 225 is communicated with a pressure sensor. The internal pressure of the airbag 225 can be sensed through the pressure sensor. The pressure sensor is a prior art technology. It can be arranged inside the airbag 225 or communicated with the airbag 225 through a pipeline to achieve the internal communication between the pressure sensor and the airbag 225 for sensing the internal pressure of the airbag 225.

[0042] During operation, when the cylinder barrel 22 approaches the filter pipe, the positioning inclined surface 224 enters the inner hole at the end of the filter pipe. At this time, the airbag 225 abuts against the edge of the inner hole of the filter pipe, achieving the sealing of the end of the filter pipe. At this time, the retaining ring 226 abuts the airbag 225 between the retaining ring 226 and the flange at the end of the filter pipe. The airbag 225 also seals between the cylinder barrel 22 and the inner hole of the filter pipe, thereby achieving the complete sealing of the end of the filter pipe.

[0043] Furthermore, referring to Figure 2 and Figure 3, a water inlet pipe 222 and a drain pipe 221 are connected to the cylinder barrel 22. The water inlet pipe 222 and the drain pipe 221 are close to the side of the retaining ring 226 away from the airbag 225. When the piston disc 229 expands and contracts, it will not block the water inlet pipe 222 and the drain pipe 221, and the water inlet pipe 222 and the drain pipe 221 can normally achieve water inlet and drainage. A stop valve 2211 is provided on the drain pipe 221. When working, the stop valve 2211 is closed. When the work is completed, the stop valve 2211 is opened to drain the water.

[0044] Working principle: Refer to Figure 1 and Figure 6 , when not working, the driving module 13 drives the two mounting plates 122 and the detection components 2 thereon to move away from each other. The piston disc 229 of the detection component 2 is driven by the spring 2292 and extends into the cylinder barrel 22. The piston disc 229 drives the slide bar 227 to contract into the cylinder barrel 22. The toothed plate 2271 on the slide bar 227 drives the gear 35 to rotate. The gear 35 drives the turning rods 3 to move away from each other until the turning rods 3 abut against the slide bar 227. At this time, the slide bar 227 stops contracting and the turning rods 3 stop moving. At this time, the slide bar 227 and the turning rods 3 are in a static state. At the same time, the sliding rod 232 of the push rod 231 abuts against the side of the driving groove 2272 away from the cylinder barrel 22.

[0045] When working, place the filter pipe in the positioning groove 112 of the positioning block 111 on the support table 11. Due to the limitation of the positioning groove 112, the filter pipe is automatically positioned, and there is no need to repeatedly move the filter pipe, and the filter pipe can be quickly installed.

[0046] After the filter pipe is installed, the two driving modules 13 simultaneously drive the two detection components 2 to approach the filter pipe. During the approaching process, the positioning inclined surface 224 at the end of the cylinder barrel 22 enters the through hole at the center of the flange at the end of the filter pipe. At this time, the airbag 225 abuts against the edge of the through hole. Under the extrusion of the cylinder barrel 22 and the retaining ring 226, the pressure in the airbag 225 continuously increases until the pressure sensor connected to the airbag 225 reaches the set pressure. At this time, the driving module 13 stops working and fixes the positions of the mounting plate 122 and the detection component 2.

[0047] During the movement of the detection component 2, the extrusion arc block 233 abuts against the flange side of the filter pipe. At this time, the extrusion arc block 233 drives the push rod 231 and the sliding rod 232 to move away from the cylinder barrel 22 relatively. The sliding rod 232 extrudes the driving groove 2272 away from the cylinder barrel 22. The driving groove 2272 drives the slide bar 227 away from the cylinder barrel 22, that is, extends out of the cylinder barrel 22. The toothed plates 2271 on both sides of the slide bar 227 drive the gear 35 to rotate. The gear 35 drives the turning rods 3 to approach and close together. At this time, the turning rods 3 drive the clamping slide plate 312 at the end of the telescopic rod 31 to move to the other side of the filter pipe flange away from the extrusion arc block 233.

[0048] Here, due to the different inner hole diameters of the filter pipes and the different test pressures, the set pressure values of the airbag 225 are different. At this time, the pressures required by the airbag 225 are also different, that is, the distances between the cylinder barrel 22 and the flanges of the filter pipes are different. In this way, it may occur that the cylinder barrel 22 moves into place and stops moving, while the clamping arc plates 312 do not contact the outer side of the filter pipe, that is, the clamping arc plates 312 can still move closer to each other.

[0049] In this case, during the sealing test, the water pressure will squeeze the piston disc 229 to move. The piston disc 229 drives the sliding rod 227 to continue to extend out of the cylinder barrel 22. The toothed plate 2271 on the side of the sliding rod 227 continues to drive the gear 35 and the turning rod 3 to turn, thereby driving the clamping arc plates 312 to move closer to each other until the clamping arc plates 312 contact the outer surface of the filter pipe. At this time, the clamping arc plates 312 stop moving, and the turning rod 3 and the gear 35 also stop moving. At this time, the sliding rod 227 and the toothed plate 2271 also stop moving, completing the installation process. During this process, since the push rod 231 stops moving, at this time the push rod 231 will no longer contact the side of the driving groove 2272, and its state is as shown in the attachment Figure 2 as shown.

[0050] It may also occur that the clamping arc plates 312 abut against the outer surface of the filter pipe, but the clamping arc plates 312 do not abut against the side of the flange. At this time, only need to press the telescopic rod 31 to make the telescopic rod 31 contract into the turning rod 3 until the clamping arc plates 312 abut against the side of the filter pipe flange to complete the installation.

[0051] After the installation is completed, water is injected into the cylinder barrel 22 through the water inlet pipe 222. The water enters the filter pipe through the cylinder barrel 22 until the required detection pressure is reached, and then the pressure is maintained to detect whether the filter pipe is sealed until the detection is completed.

[0052] After the detection is completed, the drive module 13 drives the cylinder barrel 22 away from the filter pipe. At this time, under the extrusion of the spring 2292, the piston disc 229 drives the sliding rod 227 to contract into the cylinder barrel 22. During this process, the toothed plate 2271 on the side of the sliding rod 227 drives the turning rod 3 and the telescopic rod 31 to turn outwards, and the clamping arc plates 312 move away from the filter pipe and disengage from the flange, completing the detachment of the detection assembly 2 from the filter pipe.

[0053] During the detection process, the filter can be quickly installed, and the detection assembly 2 can automatically dock and seal with the filter pipe, realizing automatic detection of the filter pipe, eliminating the complex flange docking process, and improving the detection efficiency.
