Description

Technical Field

[0001] This invention belongs to the field of friction welding processing technology, specifically a friction welding tubular workpiece loading and unloading auxiliary equipment. Background Technology

[0002] Friction welding is a method of welding that uses the heat generated by friction between the contact surfaces of workpieces as a heat source to induce plastic deformation of the workpiece under pressure. Friction welding is commonly used for welding tubular workpieces such as drill pipes. In routine friction welding production, workers need to place the joint into a friction welding chuck and then manually move the tubular workpiece to the designated friction welding position. After welding, it is moved to the next process. However, due to the high residual heat after welding, manual handling poses many safety hazards during production.

[0003] An existing auxiliary device for loading and unloading friction welding tubular workpieces (publication number CN221870636U) uses a moving device to transfer the tubes to be welded to a loading rack, thus achieving the effect of transporting the welded tubes. However, when transferring the welded tubes, this device tends to concentrate the tubes on one side, which can lead to difficulties in planning the overall production line during actual production and processing. This results in low space utilization and difficulty in coordinating with other devices. Therefore, improvements are needed. Summary of the Invention

[0004] To address the problem in existing technologies where welded pipes tend to concentrate on one side during transfer, the present invention provides an auxiliary device for loading and unloading friction-welded tubular workpieces, comprising a clamping component, a suspension component, and a limiting component. The clamping component is located inside the suspension component, and the limiting component is located at the bottom of the clamping component. The clamping component includes a main sleeve, a feed sleeve, a central rotating column, an outer rotating shell, a driven rotating column, an outer rotating shell, and an active gripper: A rotary motor is inserted into the top of the propulsion sleeve shaft, and the rotary motors on the upper and lower sides are respectively inserted into the upper and lower sides of the inner wall of the main sleeve. The propulsion sleeves on the upper and lower sides drive the main sleeve to slide up and down by pushing the rotary motors. Due to the limiting effect of the propulsion sleeve rod, the rotary motor cannot be turned. Therefore, when the rotary motor rotates the passive rotating column, the main sleeve remains stationary and does not rotate on its own. The outer surface of the rotating motor shaft is inserted into the center of the inner cavity of the shaft rotating column, the outer surface of the shaft rotating column is rotatably connected to the center of the inner wall of the main sleeve, the outer surface of the shaft rotating column is rollingly connected to the outer surface of the passive rotating column, and the outer surface of the passive rotating column is rotatably connected to the outer surface of the main sleeve through a rotating groove. The inner wall of the outer rotating cylinder shell is rotatably connected to the middle of the outer surface of the main sleeve. The outer surface of the passive rotating column is rollingly connected to the inner wall of the outer rotating cylinder shell. The active gripper is set on the outer surface of the outer rotating cylinder shell. The upper and lower push sleeves drive the active gripper to slide up and down by pushing the main sleeve up and down through the push rotation motor. The rotation motor twists the central rotating column, and drives the outer rotating cylinder shell to rotate through the transmission action, thereby driving the active gripper to rotate around.

[0005] Furthermore, the active gripper includes: An arc-shaped pressure shell, wherein traction connecting rods are symmetrically inserted into the outer surface of the arc-shaped pressure shell; An inner pressure arc plate, wherein buffer spring strips are uniformly inserted into the outer surface of the inner pressure arc plate; An external pressure plate, the inner wall of which is engaged with the middle of the outer surface of the arc-shaped pressure shell, and the inner wall of which is inserted into the end of the buffer spring belt away from the inner pressure arc plate.

[0006] Furthermore, the clamping component also includes: A connecting base plate is provided, the outer surface of which is inserted into the outer surface of the outer rotating shell via a plug rod. A biasing turntable, the outer surface of which is rotatably connected to the axis of the inner wall of the connecting base plate via a motor wheel; The torsion joint rollers are symmetrically arranged on both sides of the outer surface of the deflection turntable. Both ends of the torsion joint rollers are rotatably connected to the outer surface of the deflection turntable via torque motors. The outer surface of the torsion joint rollers is inserted into the outer surface of the arc-shaped pressure shell via traction connecting rods. When the torque motors on both sides drive the torsion joint rollers to rotate around the groove on the outer surface of the deflection turntable, they will drive the active gripper to deflect as a whole via the traction connecting rods.

[0007] Furthermore, the suspension component includes: A splicing guide rail, wherein a through groove is provided at the center of the inner cavity of the splicing guide rail; The traction machine is symmetrically arranged on the left and right sides of the inner wall of the splicing guide rail, and the inner cavity of the traction machine is slidably connected with a traction steel cable. The built-in slider has an end of the traction cable away from the traction machine inserted into the inner cavity of the built-in slider. The outer surface of the built-in slider is slidably connected to the inner wall of the splicing guide rail. An internal clamp is inserted into the outer surface of the built-in slider, and the outer surface of the internal clamp is sleeved with the outer surface of the propulsion sleeve shell. The traction machines on both sides drive the built-in slider to perform directional sliding motion by retracting and releasing the traction cable. The upper internal clamp engages with the outer surface of the upper propulsion sleeve, and the lower internal clamp engages with the outer surface of the lower propulsion sleeve.

[0008] Furthermore, the suspension component also includes: The bidirectional telescopic cylinder has its upper and lower ends inserted into the inner walls of the upper and lower side splicing guide rails, respectively. The bidirectional telescopic cylinder can adjust the spacing between the upper and lower side splicing guide rails by sliding rods on both sides, and then lock the sliding rods to achieve the effect of fixing the splicing guide rails. A fixed base plate is provided, and a protective sleeve is inserted into the top of the fixed base plate. The inner wall of the protective sleeve is sleeved with the middle part of the outer surface of the bidirectional telescopic cylinder.

[0009] Furthermore, the limiting component includes: The long box shell has a guide groove at the top of its inner cavity and supporting feet symmetrically inserted at the bottom. A passive sliding plate has a docking suction cup inserted at the center of its upper surface. The docking suction cup extends to the outside of the long box shell through a guide groove. The top of the docking suction cup is pressed against the lower surface of the bottom push sleeve. The air pump inside the passive sliding plate uses a pumping method to make the docking suction cup tightly adhere to the lower surface of the bottom push sleeve.

[0010] Furthermore, the limiting component also includes: A bending rotating rod, the top of which is inserted into the bottom of the passive sliding plate, and the end of the bending rotating rod away from the passive sliding plate is provided with sliding balls evenly arranged in a groove, and the outer surface of the sliding balls is in rolling contact with the inner wall of the long box shell. A transverse guide rail is symmetrically arranged on both sides of the bottom of the inner wall of the long box shell, and a buffer connecting rod is slidably connected to the inner wall of the transverse guide rail. The top end of the buffer connecting rod is inserted into the outer surface of the bent rotating rod.

[0011] Furthermore, the limiting component also includes: A resistance spring band is symmetrically arranged on both sides of the outer surface of the bent rotating rod, and the end of the resistance spring band near the bent rotating rod is inserted into the outer surface of the bent rotating rod through a ring sleeve. Pressure-sensitive baffles are symmetrically arranged on the left and right sides of the inner wall of the long box shell. The outer surface of the pressure-sensitive baffles is symmetrically arranged with pressure points, and the end of the resistance spring away from the bending rod is inserted into the outer surface of the pressure point.

[0012] The beneficial effects of this invention are as follows: 1. This device can facilitate the handling of welded pipe bodies, providing auxiliary loading and unloading for friction welding. During operation, the device can rotate the motor to turn the central column, allowing the welding rod clamped at the front to be moved to the welding and transfer components at the rear. This facilitates the planning of the production line layout and significantly improves the space utilization of the factory. After the welding rod is clamped, before friction welding its end, the connecting base plate can be twisted to ensure that the end of the welding rod is aligned during friction welding, thus avoiding the problem of obvious creases on the welded rod due to the misalignment of the welding rod joint.

[0013] 2. The arc-shaped pressure shells on both sides clamp the transferred welding rod through the inner pressure arc plate. Since the inner pressure arc plate can slide by squeezing the buffer spring belt, it can adapt to the actual diameter of the welding rod, ensuring stable clamping of welding rods of different models. This makes the device highly versatile. It can also dampen the clamping components through the buffer spring belt when the welding rod is being friction welded, preventing the deflection turntable and outer rotating cylinder from undergoing slight deflection under high-frequency vibration, which could lead to misalignment between the welding rod and the weld point.

[0014] 3. The upper and lower end push sleeves of the clamping component are slidably connected to the axis of the upper and lower splicing guide rails respectively, and the upper and lower splicing guide rails are kept parallel. Therefore, the clamping component can always slide in a stable vertical state, thereby avoiding the problem that the center of gravity of the clamping component shifts due to clamping a heavy welding rod on one side, which causes the welding rod to easily tip over and tilt and fail to stably align with the welding point.

[0015] 4. When the passive slide is sliding, the buffer link at the bottom can perform shock absorption and buffering work on the passive slide in the vertical direction. As the push sleeve moves in a directional manner, the resistance spring band will also increase the resistance on the clamping component, thereby decelerating the clamping component and eliminating the inertia of the clamping component. This prevents the clamping component from sliding a certain distance due to inertia when the traction machine stops working, which could lead to deviations in the placement of the welding rod.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: an auxiliary device for loading and unloading friction-welded tubular workpieces, comprising a clamping component 2, a suspension component 1, and a limiting component 3. The clamping component 2 is disposed inside the suspension component 1, and the limiting component 3 is disposed at the bottom of the clamping component 2. Clamping component 2 includes a main sleeve 21, a push sleeve 23, a spindle column 24, an outer rotating shell 26, a driven column 25, an outer rotating shell 26, and an active gripper 4. A rotary motor 22 is inserted into the top of the shaft of the push sleeve 23, and the rotary motors 22 on the upper and lower sides are respectively inserted into the upper and lower sides of the inner wall of the main sleeve 21. The push sleeves 23 on the upper and lower sides drive the main sleeve 21 to slide up and down by pushing the rotary motors 22. Due to the limiting effect of the rod of the push sleeve 23, the rotary motor 22 cannot be turned. Therefore, when the rotary motor 22 rotates the passive rotating column 25, the main sleeve 21 remains stationary and does not rotate. The outer surface of the rotating shaft of the rotating motor 22 is inserted into the center of the inner cavity of the shaft rotating column 24. The outer surface of the shaft rotating column 24 is rotatably connected to the center of the inner wall of the main sleeve 21. The outer surface of the shaft rotating column 24 is rolledly connected to the outer surface of the passive rotating column 25. The outer surface of the passive rotating column 25 is rotatably connected to the outer surface of the main sleeve 21 through a rotating groove. The inner wall of the outer rotating cylinder shell 26 is rotatably connected to the middle of the outer surface of the main sleeve 21. The outer surface of the passive rotating column 25 is rollingly connected to the inner wall of the outer rotating cylinder shell 26. The active gripper 4 is set on the outer surface of the outer rotating cylinder shell 26. The upper and lower push sleeves 23 drive the active gripper 4 to slide up and down by pushing the main sleeve 21 up and down through the push rotation motor 22. The rotation motor 22 twists the shaft rotating column 24, and drives the outer rotating cylinder shell 26 to rotate through the transmission action, thereby driving the active gripper 4 to rotate around.

[0020] The active gripper 4 includes: Arc-shaped pressure shell 42, with traction connecting rods 41 symmetrically inserted on the outer surface of the arc-shaped pressure shell 42; An inner pressure arc plate 45 has buffer spring strips 44 evenly inserted into its outer surface. The outer sensing pressure plate 43 has its inner wall snapped into the middle of the outer surface of the arc-shaped pressure shell 42, and its inner wall is inserted into the end of the buffer spring band 44 away from the inner pressure arc plate 45.

[0021] Clamping component 2 also includes: The outer surface of the connecting base plate 27 is inserted into the outer surface of the outer rotating cylinder shell 26 via a plug rod. The outer surface of the biasing turntable 28 is rotatably connected to the axis of the inner wall of the connecting base plate 27 via a motor wheel; The torsion joint roller 29 is symmetrically arranged on both sides of the outer surface of the deflection turntable 28. Both ends of the torsion joint roller 29 are rotatably connected to the outer surface of the deflection turntable 28 through a torque motor. The outer surface of the torsion joint roller 29 is inserted into the outer surface of the arc-shaped pressure shell 42 through the traction link 41. When the torque motors on both sides drive the torsion joint roller 29 to rotate around the groove on the outer surface of the deflection turntable 28, the active gripper 4 will be deflected as a whole through the traction link 41.

[0022] A transport device for supplying welded pipes is set at the front of the device, and a transport device for removing welded pipes is set at the back of the device. After the welded pipes are transported to the front of the clamping component 2, the upper and lower push sleeves 23 can adjust the actual height of the active gripper 4 by vertically pushing the main sleeve 21. After the active gripper 4 clamps the welded pipes, the rotating motor 22 drives the outer rotating cylinder shell 26 to deflect 180° by twisting the shaft rotating column 24, and transfers the clamped welded pipes to the rear position. Then, the two ends of the clamped welded pipes are friction welded by the welding equipment on the outside.

[0023] After the welding of the pipe is completed, the suspension component 1 drives the upper and lower propulsion sleeves 23 to shift laterally, transferring the pipe to the transport equipment near the back of the pipe. Then the pipe is placed on the transport device here. After unloading, the clamping component 2 is reset to the initial state and the new pipe is clamped again for friction welding.

[0024] The connecting base plate 27 changes the deflection angle of the active gripper 4 by twisting the deflection turntable 28, so that after the active gripper 4 clamps the weld pipe, it can drive the pipe body to make a certain deflection movement, thereby ensuring that the end of the pipe can be directly facing the welding end face. The torsion joint roller 29 on the deflection turntable 28 will drive the corresponding arc-shaped pressure shell 42 to cover the outer surface of the welding rod under the torque of the torque motors on both sides, thereby clamping the welding rod by pressing the welding rod with the arc-shaped pressure shells 42 on both sides.

[0025] The inner pressure arc plate 45 inside the arc-shaped pressure shell 42 is in direct contact with the outer surface of the welding rod. When clamping the welding rod, the inner pressure arc plate 45 will move towards the inner wall of the arc-shaped pressure shell 42 under the action of the extrusion force, thereby applying pressure to the outer pressure plate 43 by squeezing the buffer spring band 44. When the pressure reading of the outer pressure plate 43 reaches the standard, it means that the inner pressure arc plate 45 has been attached to the inner wall of the arc-shaped pressure shell 42. At this time, it is not necessary to continue to deflect and twist the joint roller 29, otherwise the clamping force on the welding rod will be too large, resulting in obvious indentations on the outer surface of the welding rod. When the welding rod is friction welding, it will be subjected to strong vibration due to the friction force. At this time, the active gripper 4 holding the welding rod can perform a large vibration reduction through the compressed buffer spring band 44, thereby reducing the vibration interference of the device.

[0026] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the suspension component 1 includes: The splicing guide rail 11 has a through groove at the center of its inner cavity; The traction machine 12 is symmetrically arranged on the left and right sides of the inner wall of the splicing guide rail 11, and the inner cavity of the traction machine 12 is slidably connected with the traction steel cable 13. The built-in slider 14 has one end of the traction cable 13 away from the traction machine 12 inserted into the inner cavity of the built-in slider 14. The outer surface of the built-in slider 14 is slidably connected to the inner wall of the splicing guide rail 11. The outer surface of the built-in slider 14 is inserted with a built-in clip 15, and the outer surface of the built-in clip 15 is sleeved with the outer surface of the outer shell of the push sleeve 23. The traction machines 12 on both sides drive the built-in slider 14 to perform directional sliding motion by winding and unwinding the traction cable 13. The upper built-in clip 15 engages with the outer surface of the upper push sleeve 23, and the lower built-in clip 15 engages with the outer surface of the lower push sleeve 23.

[0027] Suspension component 1 also includes: The bidirectional telescopic cylinder 17 has its upper and lower ends inserted into the inner walls of the upper and lower side splicing guide rails 11 respectively. The bidirectional telescopic cylinder 17 can adjust the spacing between the upper and lower side splicing guide rails 11 by sliding rods on both sides. Then, the bidirectional telescopic cylinder 17 locks the sliding rods to achieve the effect of fixing the splicing guide rails 11. A fixed base plate 18 is provided, and a protective sleeve 16 is inserted into the top of the fixed base plate 18. The inner wall of the protective sleeve 16 is sleeved with the middle of the outer surface of the bidirectional telescopic cylinder 17.

[0028] Limiting component 3 includes: The long box shell 31 has a guide groove at the top of its inner cavity and support feet 32 ​​symmetrically inserted at the bottom of the long box shell 31. The passive slide plate 33 has a docking suction cup 34 inserted into the center of its upper surface. The docking suction cup 34 extends to the outside of the long box shell 31 through the guide groove. The top of the docking suction cup 34 is pressed against the lower surface of the bottom push sleeve 23. The air pump inside the passive slide plate 33 presses the docking suction cup 34 tightly against the lower surface of the bottom push sleeve 23 by pumping.

[0029] The limiting component 3 also includes: The bent rotating rod 35 has its top end inserted into the bottom of the passive slide plate 33. The end of the bent rotating rod 35 away from the passive slide plate 33 is evenly provided with sliding balls 36 through a groove, and the outer surface of the sliding balls 36 is in rolling connection with the inner wall of the long box shell 31. A transverse guide rail 38 is symmetrically arranged on both sides of the bottom of the inner wall of the long box shell 31, and a buffer connecting rod 37 is slidably connected to the inner wall of the transverse guide rail 38. The top end of the buffer connecting rod 37 is inserted into the outer surface of the bent rotating rod 35.

[0030] The limiting component 3 also includes: Resistance spring band 39 is symmetrically arranged on both sides of the outer surface of the bending rod 35, and the end of the resistance spring band 39 near the bending rod 35 is inserted into the outer surface of the bending rod 35 through a ring sleeve. Pressure-sensitive baffles 310 are symmetrically arranged on the left and right sides of the inner wall of the long box shell 31. The outer surface of the pressure-sensitive baffles 310 is symmetrically arranged with pressure points, and the end of the resistance spring band 39 away from the bending rod 35 is inserted into the outer surface of the pressure point.

[0031] The traction machines 12 on both sides drive the built-in slider 14 to slide directionally along the inner wall of the splicing guide rail 11 by winding the traction steel cable 13, thereby driving the upper and lower push sleeves 23 of the clamping component 2 to move directionally through the built-in clamping clip 15.

[0032] The bottom end of the bottom push sleeve 23 is attracted and connected to the passive slide plate 33 below by the suction cup 34. When the push sleeve 23 slides directionally along the inner wall of the splicing guide rail 11, it will drive the passive slide plate 33 to slide synchronously along the inner wall of the long box shell 31. This will pressurize the pressure point of the pressure baffle 310 by compressing the resistance spring band 39, thereby triggering the pressure baffle 310. The compression amplitude of the resistance spring band 39 is judged according to the pressure reading of the pressure baffle 310, and then fed back to the traction machines 12 on both sides, so that the traction machines 12 gradually decelerate and pull, thereby avoiding the hidden danger of the clamping component 2 hitting the protective sleeve 16 on the side.

[0033] When the passive slide 33 slides, the buffer link 37 at the bottom can perform shock absorption and buffering work on the passive slide 33 in the vertical direction. As the push sleeve 23 moves in a directional manner, the resistance of the resistance spring band 39 on the clamping component 2 will also increase, thereby decelerating the clamping component 2 and eliminating the inertia of the clamping component 2. This prevents the clamping component 2 from sliding a certain distance due to inertia when the traction machine 12 stops working, thus avoiding the problem of deviation in the placement of the welding rod.

[0034] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
