Description

Technical Field

[0001] This utility model relates to the field of deburring welded pipes, and in particular to a device for rapidly removing weld burrs from precision welded pipes. Background Technology

[0002] In the production and processing of precision welded pipes, burrs often appear at the weld seam after welding. These burrs not only affect the appearance quality of the welded pipe, but may also pose safety hazards to operators during subsequent assembly, transportation and use. Therefore, the removal of weld burrs is an important process in the production of precision welded pipes.

[0003] Currently, the industry mainly uses two methods to remove burrs from the weld seams of precision welded pipes: manual removal and mechanical removal. Manual removal usually relies on operators to use hand-held grinding tools to grind the burrs. This method not only requires a high level of skill from the operators, but also has extremely low grinding efficiency, making it difficult to meet the production needs of large-volume precision welded pipes. On the other hand, existing mechanical removal devices have a low degree of automation in practical applications, requiring manual assistance to position the welded pipe and feed it into the grinding area. This not only increases labor costs, but also makes it easy for human error to cause the welded pipe feeding position to deviate, making it impossible for the grinding belt to be accurately aligned with the weld seam, thus affecting the burr removal effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a device for rapid removal of weld burrs from precision welded pipes.

[0005] The present invention provides a rapid burr removal device for precision welded pipes, which adopts the following technical solution:

[0006] A rapid burr removal device for precision welded pipes includes a fixed frame, a feeding mechanism, a loading mechanism, a grinding mechanism, a driving mechanism, and a return mechanism. The feeding mechanism and the return mechanism are both located on the same side of the fixed frame. The feeding mechanism feeds the welded pipe into the loading mechanism. The loading mechanism includes a motor, a drive wheel, a belt, a driven wheel, a rotating shaft, a connecting arm, a connecting seat, and a three-jaw external support chuck. The motor is located on the inner wall of the fixed frame, and its output end is connected to the drive wheel. The belt is tensioned between the drive wheel and the driven wheel. The driven wheel is sleeved on the end of the rotating shaft, which is rotatably connected to the fixed frame. Two sets of connecting arms are spaced apart on the rotating shaft, and each set of connecting arms has three arms arranged in a circular array along the axis of the rotating shaft. The connecting seat is located at the end of the connecting arm and has a through hole. The three-jaw external support chuck is rotatably connected to the connecting seat and is used to clamp the welded pipe fed by the feeding mechanism. The grinding mechanism is located on the top of the fixed frame, and the driving mechanism is used to drive the welded pipe inside the three-jaw external support chuck to rotate.

[0007] Optionally, the drive mechanism specifically includes a connecting frame, a fixed plate, a movable frame, a cylinder, a motor, a turntable, and a three-jaw internal support chuck. The connecting frame is disposed on the outer wall of the fixed frame, the fixed plate is disposed on the connecting frame, the cylinder is disposed on the fixed plate, the output end of the cylinder is connected to the movable frame, the bottom of the movable frame is slidably engaged with the fixed plate, the motor is fixed on the movable frame, the output end of the motor is connected to the three-jaw internal support chuck, and the three-jaw internal support chuck is coaxial with the connecting seat at the highest horizontal position in the feeding mechanism.

[0008] Optionally, the grinding mechanism includes a linear module, a moving plate, a cylinder seat, a second cylinder, a push plate, and a belt grinding assembly. The linear module is disposed on the top of the fixed frame, and the linear module drives the moving plate to move horizontally in the length direction of the rotating shaft. The cylinder seat is disposed at the bottom of the moving plate, the second cylinder is fixed on the cylinder seat, the output end of the second cylinder is connected to the push plate, and the belt grinding assembly is disposed at the bottom of the push plate.

[0009] Optionally, the grinding mechanism further includes a guide rod and a guide sleeve. The guide rod is mounted on the push plate, and the guide sleeve is mounted on the cylinder seat. The guide rod and the guide sleeve are slidably engaged.

[0010] Optionally, the feeding mechanism includes a feeding platform, an active feeding wheel set, and a driven feeding wheel set. The active feeding wheel set and the driven feeding wheel set are arranged horizontally at intervals. The welded pipe passes through the active feeding wheel set and the driven feeding wheel set. When the active feeding wheel set rotates, it drives the welded pipe to move horizontally.

[0011] Optionally, the return material mechanism has an additional set of cylinder three and pressure plate compared to the feeding mechanism. The cylinder three is located on the side of the fixed frame away from the return material mechanism. The output end of the cylinder three is connected to the pressure plate, and the pressure plate is aligned with the through hole of one of the connecting seats of the feeding mechanism.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. Under the action of the feeding mechanism, the welded pipe enters the through hole of the connecting seat of the feeding mechanism. The three-jaw external support chuck is activated to clamp the outer wall of the welded pipe. The three-jaw external support chuck and the connecting seat are rotatably connected. Therefore, when the welded pipe rotates, the three-jaw external support chuck rotates accordingly. After the three-jaw external support chuck fixes the welded pipe, motor one rotates 120 degrees to rotate the welded pipe to the top along the axis of the rotating shaft. Cylinder one drives the moving frame to move closer to the connecting seat until the three-jaw internal support chuck abuts the end of the welded pipe. The three-jaw internal support chuck can clamp the inner wall of the welded pipe. At this time, motor two can be activated to drive the welded pipe to rotate. With the help of the grinding mechanism at the top, the weld seam of the welded pipe can be ground.

[0014] 2. Cylinder 2 can control the up and down movement of the belt sanding assembly. When the feeding mechanism moves the welded pipe to the top of the work station, cylinder 2 drives the belt sanding assembly to move down to achieve the sanding of the weld seam of the welded pipe. The linear module can move the cylinder seat horizontally through the moving plate to move the belt sanding assembly to the position of the weld seam.

[0015] 3. The return material mechanism has an additional set of cylinder three and pressure plate compared to the feeding mechanism. Cylinder three is located on the side of the fixed frame away from the return material mechanism. The output end of cylinder three is connected to the pressure plate. The pressure plate is aligned with the through hole of one of the connecting seats of the feeding mechanism. After the weld seam of the welded pipe is ground, motor one rotates 120 degrees to rotate the connecting seat to the return material position. The three-jaw external support chuck is released, cylinder three starts, and drives the pressure plate to push the end of the welded pipe, thereby pushing the welded pipe to the return material mechanism to realize the automatic feeding and automatic return of the welded pipe, which greatly improves the efficiency of deburring the weld seam of the welded pipe.

[0023] Furthermore, "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] This utility model discloses a device for rapidly removing weld burrs from precision welded pipes. (Refer to...) Figure 1-4 A rapid burr removal device for precision welded pipes includes a fixed frame 1, a feeding mechanism 2, a loading mechanism 3, a grinding mechanism 4, a driving mechanism 5, and a return mechanism 6. The feeding mechanism 2 and the return mechanism 6 are both located on the same side of the fixed frame 1. The feeding mechanism 2 is used to feed the welded pipe into the loading mechanism 3.

[0025] The feeding mechanism 3 includes a motor 31, a drive wheel, a belt, a driven wheel, a rotating shaft 32, connecting arms 33, a connecting seat 34, and a three-jaw external support chuck 35. The motor 31 is mounted on the inner wall of the fixed frame 1, and its output end is connected to the drive wheel. A tensioning belt is fitted between the drive wheel and the driven wheel, forming a power transmission path. The driven wheel is fixedly fitted to the end of the rotating shaft 32, and the rotating shaft 32 is rotatably connected to the fixed frame 1 via bearings. Two sets of connecting arms 33 are spaced apart on the rotating shaft 32, each set having three arms. The three connecting arms 33 are arranged in a circular array (within a 120-degree angle) along the axis of the rotating shaft 32. The connecting seat... 34 is fixed to the end of the connecting arm 33, and the connecting seat 34 has a through hole for the welded pipe to pass through. The three-jaw external support chuck 35 is rotatably connected to the connecting seat 34 through the bearing. Its core function is to clamp the welded pipe fed by the feeding mechanism 2. The grinding mechanism 4 is mounted on the top of the fixed frame 1 and is used to remove burrs from the weld seam of the welded pipe. The drive mechanism 5 is used to drive the welded pipe inside the three-jaw external support chuck 35 to rotate in order to cooperate with the grinding operation. It is worth noting that the motor 31 is a stepper motor, and its rotation angle is precisely controlled to 120 degrees each time, thereby ensuring that the connecting arm 33 and the connecting seat 34 can stably stay at the preset position after each rotation.

[0026] The drive mechanism 5 specifically includes a connecting frame 51, a fixed plate 52, a movable frame 53, a first cylinder 54, a second motor 55, a turntable 56, and a three-jaw inner support chuck 57. The connecting frame 51 is disposed on the outer wall of the fixed frame 1, the fixed plate 52 is disposed on the connecting frame 51, the first cylinder 54 is disposed on the fixed plate 52, the output end of the first cylinder 54 is connected to the movable frame 53, the bottom of the movable frame 53 is slidably engaged with the fixed plate 52, the second motor 55 is fixed on the movable frame 53, and the output end of the second motor 55 is connected to the three-jaw inner support chuck 57. The three-jaw inner support chuck 57 is coaxial with the connecting seat 34, which is the highest horizontal position in the feeding mechanism 3.

[0027] With this design, the welded pipe enters the through hole of the connecting seat 34 of the feeding mechanism 3 under the action of the feeding mechanism 2. The three-jaw outer support chuck 35 is activated to clamp the outer wall of the welded pipe. The three-jaw outer support chuck 35 and the connecting seat 34 are rotatably connected. Therefore, when the welded pipe rotates, the three-jaw outer support chuck 35 rotates accordingly. After the three-jaw outer support chuck 35 fixes the welded pipe, the motor 1 31 rotates 120 degrees, rotating the welded pipe to the top along the axis of the rotating shaft 32. The cylinder 1 54 drives the moving frame 53 to move closer to the connecting seat 34 until the three-jaw inner support chuck 57 abuts against the end of the welded pipe. The three-jaw inner support chuck 57 can clamp the inner wall of the welded pipe. At this time, the motor 2 55 can drive the welded pipe to rotate. With the help of the grinding mechanism 4 at the top, the weld seam of the welded pipe can be ground.

[0028] The grinding mechanism 4 specifically includes a linear module 41, a moving plate 42, a cylinder seat 43, a second cylinder 44, a push plate 45, and a belt sanding assembly. The linear module 41 is located on the top of the fixed frame 1, and drives the moving plate 42 to move horizontally along the length of the rotating shaft 32. The cylinder seat 43 is located at the bottom of the moving plate 42, and the second cylinder 44 is fixed on the cylinder seat 43. The output end of the second cylinder 44 is connected to the push plate 45. The belt sanding assembly is located at the bottom of the push plate 45. The grinding mechanism 4 also includes a guide. The guide rod 47 and guide sleeve 48 are mounted on the push plate 45 and the guide sleeve 48 is mounted on the cylinder seat 43. The guide rod 47 and the guide sleeve 48 are slidably engaged. The second cylinder 44 can control the up and down movement of the belt sanding assembly. When the feeding mechanism 3 moves the welded pipe to the top position, the second cylinder 44 drives the belt sanding assembly to move downward to achieve the sanding of the weld seam of the welded pipe. The linear module 41 can drive the cylinder seat 43 to move horizontally through the moving plate 42 to move the belt sanding assembly to the position of the weld seam.

[0029] The feeding mechanism 2 includes a feeding platform 21, an active feeding wheel set 22, and a driven feeding wheel set 23. The active feeding wheel set 22 and the driven feeding wheel set 23 are arranged horizontally at intervals. The welded pipe passes between the active feeding wheel set 22 and the driven feeding wheel set 23. When the active feeding wheel set 22 rotates, it drives the welded pipe to move horizontally. The return mechanism 6 has an additional set of cylinder 3 61 and pressure plate 62 compared to the feeding mechanism 2. The cylinder 3 61 is located on the side of the fixed frame 1 away from the return mechanism 6. The output end of cylinder 3 61 is connected to pressure plate 62. Pressure plate 62 is aligned with the through hole of one set of connecting seats 34 of the feeding mechanism 3. After the weld seam of the welded pipe is ground, motor 1 31 rotates 120 degrees to rotate the connecting seat 34 to the return station. The three-jaw external support chuck 35 is released, cylinder 3 61 starts, driving pressure plate 62 to push the end of the welded pipe, thereby pushing the welded pipe to the return mechanism 6 to realize automatic feeding and automatic return of the welded pipe, which greatly improves the efficiency of deburring the weld seam of the welded pipe.

[0030] In this utility model, the driving wheel, driven wheel and belt of the feeding mechanism 3 can also be replaced by gear meshing. That is, the motor 31 drives the rotating shaft 32 to rotate through the meshing gear set, so as to prevent the rotating shaft 32 from rotating due to insufficient friction between the driven wheel and the belt when the sanding belt grinding component is working. The gear meshing transmission will not produce this problem.

[0031] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
