Description

Technical Field

[0001] The invention belongs to the technical field of automatic processing, and in particular relates to an automatic tapping processing device for a pipe elbow. Background Art

[0002] A pipe elbow is a pipe fitting used to change the direction of a pipe. To ensure the stability and tightness of the pipe connection, it is usually tapped at both ends or one end. Tapping is to cut the outer and inner diameters of the threads at the end of the pipe elbow to meet the specified tolerance range, so as to facilitate threaded connection with other pipes or equipment. This connection method can not only improve the connection strength, but also ensure the normal operation of the pipeline system, so automatic tapping equipment for pipe elbows is used.

[0003] In the Chinese patent with announcement number CN110722227B, an automatic tapping processing device for pipe elbows is mentioned, including a workbench, and also including a loading component, a feeding component, a positioning component, a tapping component and a blanking chute. The loading component is arranged on one side of the workbench, the positioning component is arranged on the top of the workbench, the feeding component is arranged on the top of the workbench, and the feeding component is located between the loading component and the positioning component, the tapping component is arranged on the top of the workbench, and the tapping component is located on the side of the positioning component away from the feeding component, the loading component includes a vibration plate, a first vibration track, a second vibration track and a limit mechanism, the blanking chute is arranged on the side of the workbench through a second bracket, and a blanking box is also provided at one end of the blanking chute. The present invention solves the problem that the pipe elbow cannot be automatically loaded and unloaded and accurately positioned during processing, improves processing efficiency, and prevents vibration during pipe elbow processing.

[0004] When the above-mentioned equipment is in use, the material moving mechanism needs to repeatedly clamp the material and send the material to the positioning component for positioning and then tapping, and then the tapped material is unloaded. This is not only cumbersome to operate but also limits work efficiency. In addition, the material moving mechanism of the equipment can only clamp one end of the elbow head, and after positioning this end, tap the other end, but cannot tap one end of the clamping point, that is, it is impossible to tap the double ports of the elbow.

The output end of the tapping motor 28 has a tapping drill bit for tapping the elbow. In addition, the bottom of the tapping motor 28 A lifting mechanism and a pushing mechanism can be installed. The lifting mechanism is used to adapt to the processing of different elbows. The pushing mechanism is used to push the tapping motor 28 so that its output end actively approaches the elbow after positioning and clamping for processing; the positioning assembly 25, the side plate assembly 26 and the stopper assembly 27 cooperate with each other for sequential loading of materials in an assembly line linkage manner; the unloading guide block 24 is composed of two abutting blocks, one is used to abut the clamping end of the elbow, and the other is used to abut the non-clamping end of the elbow, thereby pushing the elbow out of the positioning assembly 25;

[0046] The turning mechanism 3 includes a turning guide rail 31, and the turning mechanism 3 is used to adjust the tapped ports and the untapped ports of the turning pipe head;

[0047] The linkage mechanism 4 is consistent with the tapping mechanism 2, and the linkage mechanism 4 cooperates with the flip mechanism 3 to tap the untapped port of the elbow.

[0048] In a further embodiment, one end of the half-frame guide box 21 is fixedly connected to a stepper motor 22, and a threaded rod 23 is installed at the output end of the stepper motor 22. The positioning assembly 25 includes a receiving frame 251 and a receiving slider 253. The threaded rod 23 passes through one side of the threaded receiving frame 251. A lower clamping plate 252 is installed on the inner side of the receiving frame 251, and an upper clamping plate 254 is installed below the receiving slider 253.

[0049] In this embodiment, there is a slide groove on the inner side of the half-frame guide box 21, and part of the threaded rod 23 is located in the slide groove. At the same time, there is a connecting block at the back of the receiving frame 251, and the connecting block is threadedly connected by the threaded rod 23; there is a dovetail slider under the receiving frame 251, and a dovetail slide groove is also provided at the corresponding position of the half-frame guide box 21, but the dovetail slide groove is connected to the support seat 12 at the bottom, and the waste chips after tapping will fall into the inside of the support seat 12.

[0050] In a further embodiment, the upper clamp plate 254 and the lower clamp plate 252 are symmetrical in the upper and lower parts, and the two sides of the receiving slider 253 are slidingly connected to the inner side of the receiving frame 251. A spring 1 255 is arranged below the sliding connection of the receiving slider 253. A receiving plate 258 is embedded in the inner bottom surface of the receiving frame 251, and a spring 259 is fixedly connected below the receiving plate 258.

[0051] The upper clamping plate 254 and the lower clamping plate 252 are symmetrically provided with arc-shaped depressions, and rubber pads are provided in the depressions for protecting the elbow and increasing friction when the elbow is clamped. The receiving frame 251 is provided with a vertical sliding groove corresponding to the sliding connection of the receiving slider 253, and the sliding groove has a limit column inside, and the spring 1 255 surrounds the periphery of these limit columns, so that the spring 1 255 can always hold up the receiving slider 253; the receiving plate 258 is slidably connected to the inside of the receiving frame 251, and the upper surface of the receiving plate 258 is a concave arc. When the receiving slider 253 moves downward, the lower end of the elbow will first allow the receiving plate 258 to move downward so that the spring 2 259 contracts.

Fig.13 .

[0052] In a further embodiment, the side panel assembly 26 includes a baffle 261, and the block assembly 27 is slidably connected to the side of the baffle 261 close to the half-frame guide box 21. The baffle 261 is fixedly connected to the half-frame guide box 21, and the baffle 261 is provided with an inlet 262 and an outlet 263. The baffle 261 is provided with an upper slide groove 264 and a lower slide groove 266 which are symmetrical in upper and lower directions on the side close to the half-frame guide box 21.

[0053] In this embodiment, a sliding chamber is provided on the inner side of the feed port 262 to allow the bevel block 272 to be slidably connected. In addition, the sliding chamber is connected to the upper slide groove 264 through the bayonet 265, and the barrel connecting groove 267 is connected to the lower slide groove 266.

[0054] In a further embodiment, a bayonet 265 is provided on the inner wall of the upper slide groove 264, and a connecting groove 267 is provided on the inner wall of the lower slide groove 266. The bayonet 265 and the connecting groove 267 are both connected to the sliding connection of the block assembly 27. The upper slide groove 264 is internally slidably connected to an upper slide bar 256, and the lower slide groove 266 is internally slidably connected to a lower slide bar 257. Both the upper slide bar 256 and the lower slide bar 257 are fixedly connected to one side of the receiving frame 251 close to the baffle 261.

[0055] In this embodiment, the bayonet 265 allows the block 1 274 to be inserted into the interior of the upper slide groove 264, so that when the upper slide bar 256 and the lower slide bar 257 move to the left at the same time, the block 1 274 will shrink to the interior of the bevel block 272. At this time, the bottom of the block 278 is blocked by the lower slide bar 257, so there is no obstruction above and below the bevel block 272, and under the rebound of the spring three 271, the column feed port 262 will be blocked.

[0056] In a further embodiment, the block assembly 27 includes a bevel block 272 and four spring threes 271, the spring three 271 is fixedly connected to one side of the bevel block 272, the other end of the bevel block 272 is fixedly connected to the baffle 261, a slide groove 1 273 is provided inside the bevel block 272, and the inside of the slide groove 1 273 is slidably connected with a block 1 274 and a block 2 278 which are symmetrical in upper and lower directions, a connecting rod 275 is fixedly connected below the block 1 274, and a connecting slider 276 is fixedly connected below the connecting rod 275.

[0057] In this embodiment, the block 1 274, the connecting rod 275, the connecting slider 276, the spring 5 279 and the block 2 278 are fixedly connected in sequence from top to bottom. Figure 9The middle bevel block 272 is in the "feeding" state. At this time, the block 1 274 passes through the bayonet 265 and enters the interior of the upper slide 264, and is located on the left side of the upper slide bar 256. At this time, if the upper slide bar 256 and the lower slide bar 257 move to the left at the same time, the block 1 274 will be squeezed into the interior of the bevel block 272, and form a "tapping" state under the rebound of the spring three 271. At this time, the upper slide bar 256 and the lower slide bar 257 move to the right at the same time to temporarily shrink the block 2 278 into the bevel block 272. After the lower slide bar 257 passes, the block 2 278 The second 278 will pass through the connecting groove 267 again and enter the interior of the sliding groove 266, forming the "discharging" state. Finally, the upper slide bar 256 and the lower slide bar 257 move to the left at the same time and return to the "feeding" state. The above states are all caused by the operation of the stepper motor 22, which makes the receiving frame 251 slide with the positioning component 25 and the lower slide bar 257, and the sliding distance can be set in advance through the existing technical program; after the bending head is clamped by the positioning component 25, the operation of the stepper motor 22 allows the bending head to passively approach the output end of the tapping motor 28, thereby completing the tapping process.

[0058] In a further embodiment, a spring five 279 is fixedly connected to the bottom of the connecting slider 276, the lower end of the spring five 279 is fixedly connected to the upper end of the block two 278, a spring four 277 is surrounded by the periphery of the connecting rod 275, the bottom end of the spring four 277 fits into the inner wall of the slide groove one 273, the block one 274 fits into the interior of the bayonet 265, and the block two 278 fits into the interior of the connecting groove 267.

[0059] In this embodiment, when the block 1 274, the connecting rod 275, and the connecting slide block 276 are retracted into the interior of the bevel block 272 due to the upper slide bar 256, the bottom of the block 2 278 is blocked by the lower slide bar 257, so the spring 4 277 and the spring 5 279 are both compressed.

[0060] In a further embodiment, the adjustment component 29 includes a guide member 291, which is located above the receiving slider 253. An adjustment bolt 293 is rotatably connected to the top of the guide member 291. The adjustment bolt 293 penetrates through a threaded connection to the half-frame guide box 21. Guide columns 292 fixedly connected to the guide member 291 are provided on both sides of the adjustment bolt 293. The guide columns 292 penetrate through the half-frame guide box 21. The guide member 291 is composed of three sections and is used to guide the receiving slider 253.

[0061] In this embodiment, the guide member 291 is composed of three sections: left, middle and right. The right section contacts the top of the receiving slider 253, the middle section guides the receiving slider 253, and the left section is the shortest distance between the lower clamping plate 252 and the upper clamping plate 254. Therefore, by rotating the adjusting bolt 293, the overall height of the guide member 291 can be adjusted, and then the shortest distance between the lower clamping plate 252 and the upper clamping plate 254 can be adjusted, that is, the clampable diameter of the clampable elbow can be adjusted.

[0062] In a further embodiment, the upper end of the flipping guide rail 31 is fixedly connected to the periphery of the discharge port 263, the lower end of the flipping guide rail 31 is fixedly connected to the periphery of the feed port 262 of the linkage mechanism 4, the middle of the flipping guide rail 31 is fixedly connected with a protrusion 32, one side of the protrusion 32 is provided with a torsion guide piece 1 33 fixedly connected to the inner wall of the flipping guide rail 31, and the side of the protrusion 32 away from the torsion guide piece 1 33 is provided with a torsion guide piece 2 34 fixedly connected to the inner wall of the flipping guide rail 31.

[0063] In this embodiment, since the linkage mechanism 4 is the centrally symmetrical tapping mechanism 2, the flipping mechanism 3 connects the outlet (discharge port 263) of the tapping mechanism 2 and the inlet (feed port 262) of the linkage mechanism 4; the torsion guide piece 1 33 and the torsion guide piece 2 34 are connected to the inner wall of the flipping guide rail 31 through a connecting bolt; the torsion guide piece 1 33 and the torsion guide piece 2 34 are guide iron pieces with a certain toughness, so that they can be twisted to guide the bending pipe heads at different angles; the flipping mechanism 3 needs to be manually debugged before the overall use so that the flipping mechanism 3 can adjust the bending pipe head, such as Fig.10 Schematic diagram of elbow changes.

[0064] In a further embodiment, the linkage mechanism 4 and the half-frame guide box 21 are both installed above the support seat 12, a vibration plate 15 is installed above the workbench 11, the feeding end of the vibration plate 15 is fixedly connected to a loading guide rail 16, the end of the loading guide rail 16 away from the vibration plate 15 is located outside the feeding port 262 of the tapping mechanism 2, the outer periphery of the discharge port 263 of the linkage mechanism 4 is fixedly connected to a blanking guide rail 14, a collection box 13 is installed above the workbench 11, and the end of the blanking guide rail 14 away from the linkage mechanism 4 is located above the collection box 13.

[0065] In this embodiment, the vibration plate 15 and the feeding guide rail 16 are both vibration plates for feeding in the prior art; a through groove is provided at the top of the support seat 12 corresponding to the dovetail groove of the half-frame guide box 21, so that debris can enter the interior of the support seat 12. In addition, the interior of the support seat 12 has a certain inclination, so the debris can be guided to facilitate cleaning and prevent debris from accumulating in the tapping mechanism 2 or the linkage mechanism 4.

[0066] The working principle of the present invention is as follows:

[0067] When it is necessary to perform tapping on the dual ports of the assembly line linkage type elbow, after the elbow is placed inside the vibration disk 15, the vibration disk 15 is operated through external equipment so that the elbows are slowly arranged in order through vibration and the feeding guide rail 16 guides the arranged elbows to the feed port 262 opened by the baffle 261. At this time, the bevel block 272 is in an open state, and under the monitoring of the industrial camera, when a single elbow enters the interior of the positioning assembly 25, the stepper motor 22 starts to operate so that the threaded rod 23 starts to rotate forward, so that the receiving frame 251 starts to move the elbow toward the tapping motor 28, and during the movement, one end of the receiving slider 253 contacts the guide member 291 and allows the receiving slider 253 to continue to move downward, thereby clamping the elbow up and down, and after clamping, due to the continuous operation of the stepper motor 22, the clamped port of the elbow is moved by the output end of the tapping motor 28 The tapping process is carried out. After the tapping is completed, the stepper motor 22 starts to operate in the reverse direction, thereby allowing the positioning assembly 25 to move away from the tapping motor 28 until the blanking guide block 24 is plugged into the positioning assembly 25, and the elbow head is pushed out from the discharge port 263 opened by the baffle 261. At this time, the middle of the elbow head will be placed on the top of the convex frame 32, and the two ends will be in a suspended state. Since the flip guide rail 31 is inclined, the elbow head will slide, and during the sliding process, the tapped port is blocked below by the twisting guide piece 1 33, and the untapped port is held up by the twisting guide piece 2 34. As the sliding is carried out, the direction of the tapped port and the untapped port of the elbow head is reversed. At this time, the reversed elbow head will enter the interior of the linkage mechanism 4 to tap the untapped port, and after tapping, it is collected in the collection box 13 through the blanking guide rail 14 to complete the tapping of the double ports of the elbow head, as well as the assembly line linkage processing method;

[0068] First, after the elbow head enters the interior of the positioning assembly 25 through the feed port 262, Figure 9 In the state of feeding in the middle, due to the operation of the stepper motor 22, the receiving frame 251 will slide the upper slide bar 256 inside the upper slide groove 264, and let the lower slide bar 257 slide inside the lower slide groove 266. Since the bevel block 272 is in the open state at this time, the upper slide bar 256 will push the block 1 274 into the inside of the bevel block 272 when sliding in the upper slide groove 264, so that the spring four 277 and the spring five 279 will shrink. Since the lower part of the block 278 is blocked by the lower slide bar 257 at this time, the bevel block 272 will quickly close the feeding port 262 under the rebound of the spring three 271, and when closing, due to the bevel surface on one side of the bevel block 272, the two elbows arranged in contact with each other are separated, and at this time, it will be in a Figure 9Secondly, with the completion of tapping, the reversal of the stepper motor 22 causes the upper slider 256 and the lower slider 257 to slide to the right, at which time the second card block 278 is inserted into the interior of the connecting groove 267, but with the sliding of the lower slider 257, the second card block 278 will briefly enter the interior of the bevel block 272, and after the lower slider 257 passes, the second card block 278 will bounce out, and when the upper slider 256 and the lower slider 257 reach the right side of the bevel block 272, the positioning assembly 25 cooperates with the feed guide block 24, and the tapped elbow will be pushed out of the discharge port 263, and it will be in Figure 9 When the upper and lower slide bars 256 and 257 are in the state of discharging in the middle, the stepper motor 22 starts to rotate forward again after the discharging is completed, so that the upper slide bar 256 and the lower slide bar 257 slide to the left, and in the process of sliding, the lower slide bar 257 will contact the second block 278 and then slide to the left with the bevel block 272. When the block 1 274 slides to the bayonet 265, the block 1 274 quickly enters the interior of the upper slide groove 264 under the rebound of the spring four 277 and is located at the left end of the upper slide bar 256. Because the block 1 274 is connected to the slider 276 through the connecting rod 275, the spring five 279 is connected to the block 2 278, so that the block 2 278 will also shrink to the interior of the bevel block 272, so that the bevel block 272 opens the feeding port 262, and it will be in the state of discharging in the middle; finally, after the discharging is completed, the stepper motor 22 starts to rotate forward again, so that the upper slide bar 256 and the lower slide bar 257 slide to the left, and in the process of sliding, the lower slide bar 257 will contact the second block 278 and then slide to the left with the bevel block 272. Figure 9 The state of feeding in the middle, waiting for the elbow to enter and proceed to the next cycle;

[0069] When the above-mentioned elbow head enters the interior of the positioning component 25, the bottom end of the elbow head will be located above the receiving plate 258. At this time, the positioning component 25 is driven by the stepper motor 22, and the receiving slider 253 will move down with the upper clamping plate 254 when sliding, so that the upper clamping plate 254 begins to contact the upper end of the elbow head. With continued downward pressure, one side of the elbow head will contact the lower clamping plate 252, and the lower end of the elbow head will rise accordingly until the lower clamping plate 252 and the upper clamping plate 254 complete the clamping of the upper port of the elbow head. Therefore, the positioning component 25 can clamp and position elbow heads with different curvatures (such as 90° elbow heads, 60° elbow heads and 45° elbow heads).
