Description

Technical Field

[0001] The invention relates to the technical field of pipe fitting processing, and in particular to a deburring device for a pipe fitting end and a use method thereof. Background Art

[0002] During the manufacturing process of pipe fittings, especially cast pipe fittings, burrs are inevitable on the pipe fittings. In the past, manual deburring methods took a long time to process, and the operators had to work for a long time with high labor intensity. Manual deburring was inefficient and it was difficult to keep up with the rhythm of the production line during online production. Now, deburring machines are generally used to deburr pipe fittings to ensure the processing efficiency of pipe fittings.

[0003] However, when deburring the two ends of a bent pipe, the existing deburring machine generally requires the cooperation of staff. The specific working process is as follows: the staff places the bent pipe to be processed on the lower positioning seat, and then the hydraulic cylinder drives the lower positioning seat to move the bent pipe to the processing position. The upper positioning seat on the upper side of the processing position presses down the bent pipe on the lower positioning seat under the drive of the hydraulic cylinder, and then controls the motor to feed, removes the burrs on both ends of the positioned bent pipe, and then the upper positioning seat drives the deburred bent pipe to move up through a suction cup or an electromagnet, and the lower positioning seat resets and moves back under the action of the hydraulic cylinder. The upper positioning seat releases the restriction on the processed bent pipe, and the processed bent pipe automatically falls off, and the staff places another bent pipe to be processed on the reset lower positioning seat. The above-mentioned entire operation process works independently between each process action, with poor continuity, and the actions need to be performed one by one, which takes a long time to operate. At the same time, the staff waits for a long time to discharge the material each time, which occupies human resources and increases the cost of pipe processing. Summary of the invention

[0023] S2: Control the conveying motor to operate, the output shaft of the conveying motor drives the first reciprocating screw to rotate, the first movable plate moves along the axial direction of the first reciprocating screw, the first movable plate drives the lower positioning seat to move to the lower side of the upper positioning seat through the first pneumatic elastic telescopic tube, the first elastic telescopic member and the first connecting plate, and the support plate temporarily supports the bent pipe member at the bottom of the placement rack until the lower positioning seat abuts against the stopper;

[0024] S3: When the first reciprocating screw rotates, the active bevel gear meshes with the driven bevel gear on the second reciprocating screw to transmit the second movable plate along the axial direction of the second reciprocating screw. The second movable plate drives the upper positioning seat to move downward through the second pneumatic elastic telescopic tube, the second elastic telescopic member and the second connecting plate. As the first reciprocating screw continues to rotate, the first movable plate continues to move, the first pneumatic elastic telescopic tube is compressed, and the air in the first pneumatic elastic telescopic tube is introduced into the pneumatic elastic telescopic rod on the base through the air guide tube, so that the pneumatic elastic telescopic rod is stretched and inserted into the socket of the lower positioning seat, thereby locking the position of the lower positioning seat;

[0025] S4: As the second movable plate continues to move downward, the upper positioning seat is finally fitted on the lower positioning seat, the positioning rod of the upper positioning seat is inserted into the positioning hole of the limit block, the lower limit groove and the upper limit groove cooperate to position the bending pipe member, and as the first reciprocating screw and the second reciprocating screw keep rotating, the second elastic telescopic member and the second pneumatic elastic telescopic tube are continuously compressed, and the pneumatic elastic telescopic plug rod on the U-shaped frame is stretched and inserted into the plug hole of the upper positioning seat to lock the position of the upper positioning seat;

[0026] S5: When the second movable plate moves downward, it drives the pressing block to press down the force-bearing block, and the force-bearing block drives the slide seat to slide in the base, so that the rotating tool touches the end of the bent pipe and deburrs it;

[0027] S6: With the continuous operation of the conveying motor and the completion of the deburring of the bent pipe, the first movable plate moves to the end of the first reciprocating screw track groove and then starts to move back, the first pneumatic elastic telescopic tube is restored, and the pneumatic elastic telescopic plug rod on the base is contracted, releasing the movement restriction of the lower positioning seat, so that the lower positioning seat moves back with the return of the first movable plate, while the second movable plate still maintains the downward movement state along the second reciprocating screw, and the upper positioning seat cooperates with the upper limit groove to limit the processed bent pipe, so that it will not move with the lower positioning seat that moves back, and when the bottom of the lower positioning seat no longer supports the processed bent pipe during the return movement, the processed bent pipe automatically falls off;

[0028] S7: After the lower positioning seat moves to the lower side of the placement rack, the bent pipe piece at the bottom of the placement rack falls into the lower limit groove, and then the second moving plate moves to the end of the second reciprocating screw track groove and starts to move back, the second pneumatic elastic telescopic tube is restored, the upper positioning seat releases the movement restriction and moves upward, the upper positioning seat no longer limits the lateral movement of the limit block through the positioning rod, and the limit block is reset under the pull of the first elastic telescopic member, so that the limit block cooperates with the lower positioning seat to place the bent pipe piece to be processed in the lower limit groove;

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The deburring device for the end of the pipe fitting and the method of using the same drive the lifting assembly to work when the conveying mechanism is working, and the lifting assembly drives the deburring component to work when the lifting assembly is working, so as to realize the automatic loading, positioning, deburring and unloading of the bent pipe, so that the actions of each process of deburring the bent pipe are coordinated and coordinated, the fault tolerance of loading and unloading the bent pipe is reduced, the standardization and automation of the deburring process is improved, and the staff does not need to manually wait for the material to be discharged, thus shortening the working time of the pipe deburring action, reducing the workload of the staff, and improving the production efficiency of pipe deburring;

[0032] 2. The deburring device for the end of the pipe fitting and the method of using the same, by using the pneumatic elastic telescopic rod to position the lower positioning seat when the bent pipe is loaded and using the pneumatic elastic telescopic rod to position the upper positioning seat when the bent pipe is positioned, it is convenient to improve the stability of the deburring work on the end of the bent pipe and ensure the deburring quality of the bent pipe;

[0033] 3. The deburring device for the end of the pipe fitting and the method of using the same, by arranging an elastic push switch electrically connected to the deburring component on the base, when the lifting assembly drives the upper positioning seat to move downward to position the bent pipe, the elastic push switch controls the operation of the driving motor, so that the driving motor drives the tool to rotate and gradually approach the end of the bent pipe to deburr it, and when the lifting assembly drives the upper positioning seat to move upward, the elastic push switch is reset, and the deburring component no longer works, thereby preventing the tool of the deburring component from always rotating, thereby reducing the energy consumption of the deburring component when deburring is not performed, and reducing the production cost of pipe deburring.

[0058] Specifically, when the conveying mechanism is working, the conveying motor 901 is controlled to operate, and the output shaft of the conveying motor 901 drives the first reciprocating screw 902 to rotate. The first movable part 10 moves axially along the first reciprocating screw 902, so that the first movable part 10 drives the lower positioning seat 4 to move on the base 1, thereby realizing the feeding and pushing work of the lower positioning seat 4.

[0064] Specifically, when the conveying mechanism is working, the first movable plate 1001 moves axially along the first reciprocating screw rod 902, and the first movable plate 1001 drives the lower positioning seat 4 to move to the lower side of the upper positioning seat 7 through the first pneumatic elastic telescopic tube 1002, the first elastic telescopic member 1003 and the first connecting plate 1004 until the lower positioning seat 4 abuts against the stopper 102, and the conveying mechanism drives the lifting assembly to move, and the second movable plate 1311 drives the upper positioning seat 7 to move downward through the second pneumatic elastic telescopic tube 1314, the second elastic telescopic member 1312 and the second connecting plate 1313. With the continuous rotation of the first reciprocating screw rod 902, the first movable plate 1001 continues to move, the first pneumatic elastic telescopic tube 1002 is compressed, and the air in the first pneumatic elastic telescopic tube 1002 is introduced into the pneumatic elastic telescopic plug rod 12 on the base 1 through the air guide tube, so that the pneumatic elastic telescopic plug rod 12 is stretched and inserted into the socket 121 of the lower positioning seat 4, so as to achieve the locking of the position of the lower positioning seat 4;

As the first reciprocating screw rod 902 and the second reciprocating screw rod 13 keep rotating, the second elastic telescopic member 1312 and the second pneumatic elastic telescopic tube 1314 are continuously compressed, and the pneumatic elastic telescopic plug rod 12 on the U-shaped frame 6 is stretched and inserted into the insertion hole 121 of the upper positioning seat 7, thereby locking the position of the upper positioning seat 7;

[0066] As the conveying motor 901 continues to run and the deburring of the bent pipe part 3 is completed, the first movable plate 1001 moves to the end of the track groove of the first reciprocating screw 902 and then begins to move back, the first pneumatic elastic telescopic tube 1002 is restored, and the pneumatic elastic telescopic plug 12 on the base 1 contracts, releasing the movement restriction of the lower positioning seat 4, so that the lower positioning seat 4 moves back with the return of the first movable plate 1001, while the second movable plate 1311 still maintains the downward movement state along the second reciprocating screw 13, and the upper positioning seat 7 cooperates with the upper limit groove 701 to limit the processed bent pipe part 3, so that it will not move with the returning lower positioning seat 4, and after the bottom of the lower positioning seat 4 no longer supports the processed bent pipe part 3 during the return period, the processed bent pipe part 3 automatically falls off;

[0067] After the lower positioning seat 4 moves to the lower side of the placement rack 2, the bent pipe member 3 at the bottom of the placement rack 2 falls into the lower limit groove 401, and then the second movable plate 1311 moves to the end of the track groove of the second reciprocating screw 13 and begins to move back, and the second pneumatic elastic telescopic tube 1314 is restored, and the upper positioning seat 7 releases the movement restriction and moves upward.
