The driving rod 345 is connected with the threaded column 32 through a transmission part 346, the transmission part 346 comprises a rotary bevel gear 3461 fixedly installed at the lower end of the driving rod 345, the lower part of the device frame 1 is symmetrically arranged left and right in a rotary mode, the rotary bevel gear 3462 is meshed with the rotary bevel gear 3461, a rotary tray 3463 is rotatably arranged on one side, far away from the device frame 1, of the sliding frame 31, the rotary tray 3463 is slidably sleeved on the outer side of the lower portion of the threaded column 32, and a tensioning structure 3464 is symmetrically arranged on the front part of the device frame 1 in a left and right mode.
Referring to fig. 1, 4, 6, 7, 8, 9 and 10, the tensioning structure 3464 includes a sliding rail plate 34641 fixedly mounted on the front portion of the device frame 1, a tensioning block 34642 is slidably disposed on the lower portion of the sliding rail plate 34641 back and forth, a tensioning wheel 34643 is rotatably disposed on the tensioning block 34642, a tensioning spring is disposed between the tensioning block 34642 and the device frame 1, and a belt is wound between the tensioning wheel 34643, the rotating disc plate 3463 and the transmission bevel gear 3462 at corresponding positions.
When the driving rod 345 rotates forward, the driving rod 345 drives the rotating bevel gear 3461 to rotate synchronously and positively, the rotating bevel gear 3461 drives the driving bevel gears 3462 on two sides to rotate synchronously and reversely, the driving bevel gears 3462 drive the rotating disc plates 3463 on corresponding positions to rotate synchronously and reversely through the tensioning wheels 34643, the rotating disc plates 3463 drive the threaded columns 32 on corresponding positions to rotate synchronously and reversely, the threaded columns 32 move to a direction close to an elbow through the threaded fit with the sliding frame 31, the threaded columns 32 drive the tap 33 to feed to the elbow orifice rapidly and simultaneously accelerate and rotate reversely, and the tap 33 taps the elbow orifice rapidly.
It should be noted that, since the drive bevel gears 3462 are respectively meshed with both sides of the rotation bevel gear 3461, the rotation directions of the two drive bevel gears 3462 are the same, so that the two taps 33 machine the internal threads of the two pipe orifices of the elbow in the same rotation direction.
It should be noted that, the tensioning block 34642 is pushed to move forward by the tensioning spring, so that the tensioning block 34642 drives the belt to be always in a tensioned state by the tensioning wheel 34643, when the clamping block 22 and the V-shaped block 21 clamp elbow pipe orifices with different diameters, the moving distance of the V-shaped block 21 is different, so that the moving distance of the sliding frame 31 is changed, the sliding frame 31 drives the rotating disc plate 3463 to move synchronously, and the transmission bevel gear 3462 is always connected with the rotating disc plate 3463 at the corresponding position.
When the driving pressure plate 3473 at the lower side is attached to the driven pressure plate 3474 at the lower side, the rotating tube 341 is continuously rotated, and the moving plate 3472 continuously moves downwards, so that the moving plate 3472 compresses the pushing spring and the restoring spring at the lower side, the driven pressure plate 3474 at the lower side continuously rotates forwards, and the tap 33 continuously performs internal thread processing on the elbow pipe orifice.
When the reciprocating screw groove 3471 drives the moving plate 3472 to move up to the middle of the rotating tube 341, the lower return spring pushes the lower driving pressure plate 3473 to move up to the initial position, so that the lower driving pressure plate 3473 is out of contact with the lower driven pressure plate 3474, and the tap 33 stops feeding and rotating, so that the internal thread processing of the elbow pipe orifice is stopped.
Then, the reciprocating thread groove 3471 drives the moving plate 3472 to move upwards continuously, so that the moving plate 3472 pushes the upper driving pressure plate 3473 to move upwards synchronously through the upper pushing spring, the upper driving pressure plate 3473 is attached to the upper driven pressure plate 3474, the upper driven pressure plate 3474 drives the driving gear 3475 to rotate forwards, the driving gear 3475 drives the driving rod 345 to rotate backwards through the driven gear 3476, the driving rod 345 drives the tap 33 to rotate forwards through the rotating bevel gear 3461, the tap 33 moves away from the elbow pipe orifice, and the tap 33 brings metal scraps inside the elbow pipe orifice.
It should be noted that, because the tap 33 is accelerated to rotate relative to the rotating tube 341 when feeding, the tap 33 is rotated at a constant speed relative to the rotating tube 341 when backing, and because the feeding and backing times of the tap 33 are equal, the feeding distance of the tap 33 is greater than the backing distance of the tap 33 each time, so that the tap 33 can intermittently perform internal thread processing on the elbow pipe orifice, and intermittently discharge metal chips into the elbow pipe orifice.
Referring to fig. 1,4, 5 and 6, the tap 33 is provided with a scraping assembly 35 for driving scraps to the outside, the scraping assembly 35 comprises scraping plate members 351 which are arranged on the tap 33 at equal intervals along the circumferential direction of the tap 33, the scraping plate members 351 are in sliding connection with the tap 33 along the radial direction of the tap 33, tension springs are arranged between the scraping plate members 351 and the tap 33, a damping telescopic rod 352 is arranged in the threaded column 32 along the axial sliding direction of the screw column, one end, close to the tap 33, of the damping telescopic rod 352 is fixedly provided with a conical block 353, and a telescopic section of the damping telescopic rod 352 is fixedly connected with the lower part of the device frame 1.
When the tap 33 feeds in the direction close to the elbow, the damping telescopic rod 352 pulls the conical block 353 not to contact with the scraper plate 351, so that the scraper plate 351 is contracted in the inside of the tap 33 under the pulling of the tension spring, when the tap 33 is prevented from driving the scraper plate 351 to feed, the scraper plate 351 pushes metal scraps into the inside of the elbow, when the tap 33 retreats in the direction far away from the elbow, the damping telescopic rod 352 pushes the conical block 353 to lean against the scraper plate 351, the conical block 353 pushes the scraper plate 351 out of the inside of the tap 33, the outer side face of the scraper plate 351 is propped against the inner wall of the orifice of the elbow, and when the tap 33 drives the scraper plate 351 to retreat, the scraper plate 351 pulls the metal scraps out of the inside of the elbow.
When the pipe orifice of the stainless steel 90-degree elbow is internally threaded, the invention further comprises the following steps: first, the operator places the pipe orifice of the elbow downward on the upper portion of the V-shaped block 21, and then the operator manually rotates the rotating threaded rod 231 to drive the two clamping blocks 22 to abut against the upper side of the pipe orifice of the elbow, so that the clamping blocks 22 and the V-shaped block 21 cooperate to clamp and lock the position of the elbow.
In the second step, the clamping block 22 pushes the synchronizing member 243 to move to the coaxial position of the elbow pipe orifice through the follower rod 241, and the synchronizing member 243 drives the tap 33 to synchronously move to the coaxial position of the elbow pipe orifice through the sliding frame 31.
Third, operating personnel rotates the crank 343, and the crank 343 drives the tap 33 to the quick feed of elbow mouth of pipe and reverse acceleration rotation simultaneously to make the tap 33 carry out the tapping to elbow mouth of pipe fast, simultaneously, scrape the inside shrink at tap 33 under the pulling of extension spring of plate 351, avoid scraping plate 351 to promote metal chip to the inside of mouth of pipe.
Fourth, the crank 343 drives the tap 33 to move away from the direction of the pipe orifice of the elbow, so that the tap 33 brings out metal scraps inside the pipe orifice of the elbow, and meanwhile, the damping telescopic rod 352 pushes the conical block 353 to lean against the scraper plate 351, so that the outer side surface of the scraper plate 351 leans against the inner wall of the pipe orifice of the elbow, and when the tap 33 drives the scraper plate 351 to retreat, the scraper plate 351 pulls out the metal scraps inside the elbow.
