Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a deburring fixture for steel pipe processing. Background Technology

[0002] During steel pipe processing, long steel pipes need to be cut, and burrs will be generated on the cut surface during this process. The presence of burrs can affect the quality of the steel pipe, and may cause scratches to operators or other parts during assembly or use. It is also possible that burrs will fall off and enter the hydraulic / pneumatic system during use, causing blockages and reducing the risk of equipment downtime.

[0003] Therefore, it is necessary to remove the burrs from the steel pipes. Most steel pipe deburring equipment on the market directly feeds the steel pipes to the grinding area for grinding without stabilizing them, which may lead to uneven stress and affect the processing effect. Some equipment is equipped with a clamping and stabilizing mechanism, but the opening and closing of this mechanism takes time, resulting in long processing intervals and affecting processing efficiency. Utility Model Content

[0004] This utility model discloses a deburring fixture for steel pipe processing, which aims to solve the technical problem that the long opening and closing time of the clamping mechanism affects the efficiency of steel pipe deburring.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A deburring fixture for steel pipe processing includes two grinding machines, each of which has a movable grinding disc, and further includes:

[0007] The clamping mechanism, located between two grinding machines, is used to rotate and transfer multiple steel pipes, and to individually clamp the steel pipes at the grinding position during the transfer process to maintain their stability during the grinding process.

[0008] The adjustment mechanism is connected to the bottom of the two grinders and the clamping mechanism respectively, and is used to adjust the distance between the two grinders and the clamping distance of the clamping mechanism.

[0009] The guiding mechanism is fixedly connected to one side of the clamping mechanism and is used to guide the polished steel pipe and remove the debris from the polished surface of the steel pipe by vibration.

[0010] The clamping mechanism includes:

[0011] The main support frame is located between the two grinding machines, and a snap-fit ​​seat is fixedly connected to the top outer wall of the main support frame;

[0012] A circular support plate has a snap-fit ​​edge fixedly connected to its outer circumference, and the circular support plate is movably snapped into the snap-fit ​​seat through the snap-fit ​​edge.

[0013] The motor is fixedly mounted on the main support frame;

[0014] The clamping mechanism further includes:

[0015] Gear 2 is fixedly connected to the output shaft of the motor via support shaft 1;

[0016] Gear one engages with the outer wall of gear two.

[0017] Two circular brackets are symmetrically distributed on both sides of the snap-fit ​​base, and multiple limiting plates are fixedly connected to the outer circumference of each circular bracket at equal intervals.

[0018] The clamping mechanism further includes:

[0019] Two central supports are fixedly connected to the center positions of two circular supports respectively;

[0020] The U-shaped bracket is fixedly connected to the top outer wall of the card holder, and the two ends of the U-shaped bracket are respectively fixedly connected to the sleeves;

[0021] The clamping mechanism further includes:

[0022] Support shaft two is rotatably connected to the U-shaped bracket, and both ends of support shaft two pass through the two ends of the U-shaped bracket respectively;

[0023] Two support shafts three are fixed to the two ends of support shaft two respectively. Each support shaft three has a torsion spring fixedly connected to one side of its outer wall, and the other end of the torsion spring is fixedly connected to the inner wall of the sleeve.

[0024] The clamping plate, located between the two circular brackets and fixedly connected to the outer wall of one side of the support shaft, is used to assist the limiting plate in clamping the steel pipe.

[0025] By incorporating a clamping mechanism, the steel pipe is rotated and moved. When the steel pipe reaches the uppermost area, it can be clamped by the clamping plate and the limiting plate to ensure stability during processing. As the rotation continues, the steel pipe pushes the clamping plate until it detaches from the surface of the steel pipe, and the steel pipe falls off. This structure ensures processing stability while also shortening the clamping time required by the fixture, thereby improving work efficiency.

[0026] In a preferred embodiment, the adjusting mechanism includes:

[0027] A sleeve is provided, and a mounting bracket is fixedly connected to one outer wall of the sleeve. The sleeve and the mounting bracket are simultaneously fixedly connected to the circular support plate, and a gear is fixedly connected to the outer wall of the sleeve and the mounting bracket.

[0028] The sliding groove is installed throughout the sleeve;

[0029] Electric double-headed telescopic rod, fixedly connected to the inner wall of the mounting frame;

[0030] The adjustment mechanism further includes:

[0031] Two support shafts are fixedly connected to the inner walls of opposite sides of the two central supports, and the outer periphery of the support shafts is fixedly connected with locking strips. The two support shafts extend into the two ends of the slide groove and are movably locked into the slide groove by the locking strips.

[0032] Two connecting plates are fixedly connected to the outer wall of the same side of the two support shafts, and the two output ends of the electric double-headed telescopic rod are fixedly connected to the two connecting plates respectively. The electric double-headed telescopic rod is used to adjust the distance between the two ring supports.

[0033] The adjustment mechanism also includes:

[0034] Two sliders are fixedly connected to the bottom outer walls of the two grinders, respectively;

[0035] A bidirectional linear electric guide rail, with two sliders symmetrically and movablely connected to it, is used to adjust the distance between two grinders.

[0036] The system is equipped with an adjustment mechanism. The distance between the two grinding machines can be changed by a bidirectional linear electric guide rail, thus adapting to the use of steel pipes of different lengths. In addition, the distance between the two circular supports can be changed by the action of an electric double-headed telescopic rod, making it suitable for processing steel pipes of different specifications.

[0037] In a preferred embodiment, the guiding mechanism includes:

[0038] Connecting support plates are fixedly connected to one side of the outer wall of the main support frame;

[0039] The guide ramp is fixedly connected to one side of the outer wall of the main support frame, and its bottom end slopes downwards.

[0040] The guiding mechanism also includes:

[0041] Multiple protruding strips are fixedly connected at equal intervals to one side of the outer wall of the guide slope;

[0042] A conveyor belt is installed at the bottom of a guide ramp, which is used to guide the falling steel pipes, and the ribs are used to cause the steel pipes to vibrate during the falling process.

[0043] With a guiding mechanism, the steel pipe moves along the slope of the guide ramp, passing through multiple protrusions. This causes vibrations in the steel pipe, causing the debris adhering to both ends to fall off under the action of vibration, thus completing the cleaning of the debris generated during grinding.

[0044] As described above, a deburring fixture for steel pipe processing includes two grinding machines, each with a movable grinding disc. It also includes: a clamping mechanism positioned between the two grinding machines for rotating and transporting multiple steel pipes, and individually clamping the steel pipe at the grinding position during transport to maintain stability during grinding; an adjusting mechanism connected to the bottom of the two grinding machines and the clamping mechanism for adjusting the distance between the two grinding machines and the clamping distance of the clamping mechanism; and a guiding mechanism fixedly connected to one side of the clamping mechanism for guiding the ground steel pipe and removing debris from the ground surface of the steel pipe through vibration. The deburring fixture for steel pipe processing provided by this utility model ensures processing stability while shortening the clamping time and improving work efficiency.

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0051] The present invention discloses a deburring fixture for steel pipe processing, which is mainly used in the scenario of steel pipe deburring.

[0052] Reference Figure 1 A deburring fixture for steel pipe processing includes two grinding machines 2, each grinding machine 2 having a movable grinding disc 3, and further includes:

[0053] The clamping mechanism 4 is located between the two grinding machines 2. It is used to rotate and transfer multiple steel pipes, and to clamp the steel pipes at the grinding position individually during the transfer process to maintain their stability during the grinding process.

[0054] The adjustment mechanism 5 is connected to the bottom of the two grinding machines 2 and the clamping mechanism 4 respectively, and is used to adjust the distance between the two grinding machines 2 and the clamping distance of the clamping mechanism 4.

[0055] The guiding mechanism 1 is fixedly connected to one side of the clamping mechanism 4 and is used to guide the polished steel pipe and remove the debris from the polished surface of the steel pipe by vibration.

[0056] Reference Figure 2 In a preferred embodiment, the clamping mechanism 4 includes:

[0057] The main support frame 408 is located between the two grinding machines 2, and a snap-fit ​​seat 409 is fixedly connected to the top outer wall of the main support frame 408;

[0058] A circular support plate 411 has a snap-fit ​​edge 410 fixedly connected to its outer circumference, and the circular support plate 411 is movably snapped into the snap-fit ​​seat 409 through the snap-fit ​​edge 410.

[0059] Motor 407 is fixedly installed on main support frame 408.

[0060] Reference Figure 2 In a preferred embodiment, the clamping mechanism 4 further includes:

[0061] Gear 2 405 is fixedly connected to the output shaft of motor 407 via support shaft 1 406;

[0062] Gear 1, 404, engages with the outer wall of gear 2, 405.

[0063] Two circular brackets 402 are symmetrically distributed on both sides of the snap-fit ​​base 409, and multiple limiting plates 401 are fixedly connected at equal intervals to the outer circumference of each circular bracket 402.

[0064] Reference Figure 2 and Figure 3 In a preferred embodiment, the clamping mechanism 4 further includes:

[0065] Two central supports 403 are fixedly connected to the center positions of two circular supports 402 respectively;

[0066] The U-shaped bracket 412 is fixedly connected to the top outer wall of the snap-fit ​​base 409, and the two ends of the U-shaped bracket 412 are respectively fixedly connected to the sleeve 417.

[0067] Reference Figure 3 In a preferred embodiment, the clamping mechanism 4 further includes:

[0068] Support shaft 2 414 is rotatably connected to U-shaped bracket 412, and both ends of support shaft 2 414 pass through both ends of U-shaped bracket 412 respectively;

[0069] Two support shafts 3 416 are fixed to both ends of support shaft 2 414 respectively. A torsion spring 415 is fixedly connected to one side of the outer wall of each support shaft 3 416, and the other end of the torsion spring 415 is fixedly connected to the inner wall of the sleeve 417.

[0070] The clamping plate 413, located between the two annular supports 402 and fixedly connected to one side of the outer wall of the support shaft 414, is used to assist the limiting plate 401 in clamping the steel pipe. The clamping mechanism 4 moves the steel pipe between the two grinding machines 2 by placing it on the corresponding two limiting plates 401 and rotating the annular supports 402. The burrs at both ends of the steel pipe are ground by the movable grinding disc 3. When the steel pipe moves to the uppermost area, it contacts the clamping plate 413, and the clamping plate 413 and the steel pipe can be clamped together. The limiting plate 401 clamps the steel pipe to ensure stability during processing. As it rotates continuously, the limiting plate 401 pushes the steel pipe, causing the torsion spring 415 to compress until the clamping plate 413 detaches from the surface of the steel pipe. The steel pipe falls as it moves. After the clamping plate 413 detaches from the steel pipe, it springs back to its original position under the action of the torsion spring 415, clamping and limiting the steel pipe at the next position. With this structure, while ensuring processing stability, the clamping time required by the fixture can also be shortened, thereby improving work efficiency.

[0071] Reference Figure 2 In a preferred embodiment, the adjusting mechanism 5 includes:

[0072] A sleeve 504 is provided, and a mounting bracket 505 is fixedly connected to one outer wall of the sleeve 504. The sleeve 504 and the mounting bracket 505 are simultaneously fixedly connected to the circular support plate 411, and a gear 404 is fixedly connected to the outer walls of the sleeve 504 and the mounting bracket 505.

[0073] The slide groove 506 is provided through the sleeve 504;

[0074] The electric double-headed telescopic rod 503 is fixedly connected to the inner wall of the mounting bracket 505.

[0075] Reference Figure 2 In a preferred embodiment, the adjusting mechanism 5 further includes:

[0076] Two support shafts 507 are fixedly connected to the inner walls of opposite sides of two central supports 403, and the outer periphery of the support shafts 507 is fixedly connected with a retaining strip 508. The two support shafts 507 extend into the two ends of the slide groove 506 respectively, and are movably engaged in the slide groove 506 by the retaining strip 508.

[0077] Two connecting plates 509 are fixedly connected to the outer wall of the same side of the two support shafts 507, and the two output ends of the electric double-headed telescopic rod 503 are fixedly connected to the two connecting plates 509 respectively. The electric double-headed telescopic rod 503 is used to adjust the distance between the two ring brackets 402.

[0078] Reference Figure 1 In a preferred embodiment, the adjusting mechanism 5 further includes:

[0079] Two sliders 501 are fixedly connected to the bottom outer walls of the two grinding machines 2 respectively;

[0080] The bidirectional linear electric guide rail 502 has two sliders 501 symmetrically and movably connected to it, used to adjust the distance between the two grinding machines 2. In the adjustment mechanism 5, the bidirectional linear electric guide rail 502 drives the two sliders 501 to move in relative or opposite directions, thereby changing the distance between the two grinding machines 2, thus adapting to the use of steel pipes of different lengths. In addition, based on the fact that the support shaft 407 is movably engaged in the slide groove 506 under the action of the locking strip 508, the distance between the two circular brackets 402 can be changed under the action of the electric double-headed telescopic rod 503, without changing the rotational transmission of the gear 404 to the support shaft 407 through the sleeve 504, thus enabling it to adapt to the processing of steel pipes of different specifications.

[0081] Reference Figure 4 In a preferred embodiment, the guide mechanism 1 includes:

[0082] The connecting plate 103 is fixedly connected to one side of the outer wall of the main support frame 408;

[0083] The guide ramp 102 is fixedly connected to one side of the outer wall of the main support frame 408, and its bottom end is inclined downwards.

[0084] Reference Figure 1 and Figure 4In a preferred embodiment, the guiding mechanism 1 further includes:

[0085] Multiple protrusions 104 are fixedly connected at equal intervals to one side of the outer wall of the guide ramp 102;

[0086] The conveyor belt 101 is located at the bottom of the guide ramp 102. The guide ramp 102 is used to guide the falling steel pipe, and the protrusions 104 are used to make the steel pipe vibrate during the falling process. When the processed steel pipe falls with the rotation of the clamping mechanism 4, it is located at the top of the guide ramp 102. Then the steel pipe rolls down the slope of the guide ramp 102 to the conveyor belt 101 for conveying to the next process. During the process, it passes through multiple protrusions 104, which causes the steel pipe to vibrate during the movement, causing the debris adhering to both ends to fall off under the action of vibration, thus completing the cleaning of the debris generated by grinding.

[0087] Working principle: The clamping mechanism 4 places the steel pipe on two corresponding limiting plates 401, and the rotation of the ring bracket 402 pushes the steel pipe to move between the two grinding machines 2. The burrs at both ends of the steel pipe are ground by the movable grinding disc 3. When the steel pipe moves to the uppermost area, it contacts the clamping plate 413. The clamping plate 413 and the limiting plate 401 clamp the steel pipe to ensure its stability during processing. As the rotation continues, the limiting plate 401 pushes the steel pipe, which causes the torsion spring 415 to compress until the clamping plate 413 is removed from the surface of the steel pipe. The steel pipe falls down as it moves. After the clamping plate 413 is removed from the steel pipe limiting position, it rebounds and returns to its original position under the action of the torsion spring 415 to clamp and limit the steel pipe at the next position. With this structure, while ensuring processing stability, the clamping time required by the fixture can also be shortened to improve work efficiency.

[0088] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
