2. Automatic hole expanding mechanism 3

The automatic reaming mechanism 3 comprises two hydraulic pipe expanders 301 which respectively correspond to the two ends of the pipe fitting. Three clamping mechanisms 302 are arranged between the two hydraulic pipe expanders 301; the clamping mechanism 302 comprises a clamping frame 3021, a clamping head 3022 is slidably connected to the bottom of the clamping frame 3021, and an air cylinder for driving the clamping head 3022 to clamp or separate is arranged in the clamping frame 3021 (the structure is an existing clamping structure and is not described any more).

The clamping frame 3021 is fixedly connected with a fixed seat 3023. The fixed seat 3023 is fixedly connected with a push plate 3024, and the push plate 3024 is fixedly connected with two push rods 3025. The two push rods 3025 are fixedly connected with the same push cylinder 3026. The pushing cylinder 3026 is connected with a lifting block 3027. The top of the lifting block 3027 is fixedly connected with a lifting plate 3028.

The driving cylinder 307 is fixedly connected with the sliding frame 303.

The working process comprises the following steps:

(1) A clamping process:

when a single pipe fitting is placed on the magnet 209 and the placing rack 208, the driving cylinder 307 drives the sliding rack 303 to move towards the position of the magnet 209. When the clamping head 3022 corresponds to one side of a single pipe, the clamping head 3022 is separated by the driving of the cylinder. Thereafter, the gripping heads 3022 are moved towards the position of the single tubular until reaching the top of the tubular by the pushing cylinder 3026, after which the gripping heads 3022 are moved to the position of the tubular by the lifting cylinder so that the tubular is between the gripping heads 3022. The cylinder drives the clamping head 3022 to clamp the pipe fitting, thereby achieving the process of clamping the pipe fitting.

(2) The first processing process comprises the following steps:

after the pipe fitting is clamped, the pipe fitting moves upwards under the driving of the lifting cylinder. The pushing cylinder 3026 drives the pipe fitting to be far away from the magnetic block 209. Drive actuating cylinder 307 and drive the pipe fitting and remove one side position department to first hydraulic pipe expander 301, later lift cylinder makes the pipe fitting remove to with hydraulic pipe expander 301 parallel and level, under the drive of pushing cylinder 3026, the pipe fitting removes towards hydraulic pipe expander 301, finally makes the pipe fitting cup joint on hydraulic pipe expander 301's expanding head 3011. The hydraulic pipe expander 301 works to complete the reaming of one end of the pipe fitting, so that the first machining process is realized.

(3) And (3) a second processing process:

after the first machining process is completed, the middle clamping mechanism 302 of the three clamping mechanisms 302 is driven by the driving cylinder 307 to move to the position of the hydraulic pipe expander 301, and meanwhile, the clamping mechanism 302 close to the magnetic block 209 continues to clamp a new unprocessed pipe fitting. The clamping mechanism 302 in the middle moves towards the pipe after the first processing on the hydraulic pipe expander 301 under the action of the lifting mechanism and the pushing cylinder 3026, and finally clamps the pipe after the first processing. Then, the clamping mechanism 302 in the middle part conveys the pipe fitting to the hydraulic pipe expander 301 for the second processing, and performs reaming processing on the other end of the pipe fitting. Since the overall process is similar to the above process, it is not described in detail.

(4) The recovery process comprises the following steps:

after the second machining process is completed, the clamping mechanism 302 on the outermost side clamps the pipe subjected to the second machining process from the hydraulic pipe expander 301, and the pipe reaches the position of the recovery mechanism 4 to be recovered, so that the whole machining process is completed.

The three clamping mechanisms 302 work simultaneously, so that the processes of clamping the pipe fitting, processing the pipe fitting for the first time, processing the pipe fitting for the second time and recovering the processed pipe fitting are performed simultaneously, and the operation of the whole system is controlled by the sensor and the PLC component.

In addition, the opposite sides of the two hydraulic pipe expanders 301 are respectively provided with a pressing cylinder 308 for pressing a pipe fitting sleeved on the expansion head 3011, one end of the pressing cylinder 308 is connected with a pressing head 309, and the pressing cylinder 308 is fixedly connected with the base 1.

3. Recovery mechanism 4

The recovery mechanism 4 includes a recovery tank 401. A material collecting block 402 is arranged on one side of the recovery tank 401. The material collecting block 402 is provided with a slope 403. After the gripping mechanism 302 moves the finished pipe to the position of the recovery tank 401, the pipe falls onto the inclined surface 403 and is guided into the recovery tank 401 through the inclined surface 403 to complete the recovery of the pipe.

Example 2:

as shown in fig. 5 to 7, the difference from embodiment 1 is that the following scheme is provided in order to solve the problem of automatic screening of inferior products after pipe processing in the present invention: the recovery mechanism 4 comprises a recovery frame 404, and a material collecting block 402 is connected to one side of the base 1 in a sliding manner. The material receiving block 402 is provided with an inclined plane 403. The inclined surface 403 is provided with a plurality of mounting grooves 405, the base 1 is provided with a material receiving plate 406 at one side of the material receiving block 402, and a spring (not shown) is fixedly connected between the material receiving plate 406 and the base 1. The back side of the material receiving plate 406 is abutted with a support rod 407, the other end of the support rod 407 is connected with a pushing cylinder 408, and the pushing cylinder 408 is fixedly connected with the support column 306. One side of the material collecting block 402 is provided with a bearing seat 409, the bearing seat 409 is provided with a first gear 410, one side of the bearing seat 409 is connected with a piston rod 412, the piston rod 412 is connected with a fixed air cylinder 413, one side of the fixed air cylinder 413 is fixedly connected with a rotating motor 414, the rotating motor 414 is connected with a rotating rod 415, and one end of the rotating rod 415 is fixedly connected with a second gear 411 matched with the first gear 410.

The recovery working process comprises the following steps:

when the clamping mechanism 302 puts the finished pipe between the material receiving block 402 and the material receiving plate 406, the support rod 407 is driven to move by the pushing cylinder 408. The support rods 407 move to move the material receiving plate 406 toward the position of the material receiving block 402. The pipe fitting that is in between material receiving plate 406 and material receiving block 402 moves to the position department of inclined plane 403 under the drive of material receiving plate 406, and simultaneously, because the complete machine during operation can produce the vibration, make the pipe fitting become horizontal under vibrations, in-process at material receiving plate 406 removal to inclined plane 403, horizontal pipe fitting matches one by one with the arrangement groove 405 on the inclined plane 403, the pipe fitting that matches successfully can the butt accomplish the arrangement in arrangement groove 405, the specification after the reaming of explanation pipe fitting is according with the standard, if mismatch then can't accomplish the arrangement, get back again between material receiving plate 406 and material receiving block 402. Thereafter, the push cylinder 408 is operated in the reverse direction, so that the material receiving plate 406 no longer abuts against the holder bar 407. The receiving plate 406 returns to its original position under the action of the spring. The material collecting block 402 is driven by the fixing cylinder 413 to move outwards to the position of the material collecting rack 404, and at this time, the first gear 410 is meshed with the second gear 411. The rotating motor 414 drives the rotating rod 415 to rotate, so that the second gear 411 drives the first gear 410 to rotate for a half cycle, and finally drives the bearing block 409 to rotate, and the bearing block 409 rotates to drive the material collecting block 402 to rotate, so that the standard-met pipes on the material collecting block 402 fall into the recovery rack 404 to complete recovery. Then, the rotating motor 414 rotates in the reverse direction, so that the material collecting block 402 returns to the original position and enters the base 1 again for the subsequent recovery process under the driving of the fixed cylinder 413. In the above process, the reversed second gear 411 drives the first gear 410 to return to the original position, so that the problem that the first gear 410 and the second gear 411 cannot be meshed subsequently does not exist. The recovery scheme can effectively screen out the pipe fittings which do not meet the standard, and subsequent quality screening is not needed. However, this solution can only screen out pipes that cannot enter the seating groove 405 due to over-reamed holes, and cannot screen out pipes that are under-reamed holes, so there is room for further improvement.
