Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a welding auxiliary device for circular workpieces. Background Technology

[0002] Medical devices, broadly speaking, refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are used directly or indirectly on the human body, including the necessary computer software. Currently, common medical devices in hospitals include operating tables, hospital beds, surgical lights, monitors, anesthesia machines, ventilators, blood cell analyzers, differentiation analyzers, enzyme-linked immunosorbent assay (ELISA) readers, plate washers, urine analyzers, ultrasound machines, and so on. In routine emergency or nursing care in hospitals, trolleys or carts are typically used to store various medications, medical devices, or medical equipment, facilitating their transfer to the required locations. These related devices and instruments typically involve many components. The components of medical instruments used in different scenarios vary in shape and specification. For example, towers and trolleys often require various connection and support structures, necessitating the installation of connectors and other parts on circular tubes. After connecting two components, welding is usually required to ensure the stability of the connection. When connectors are attached to the wall of a circular tube, because the tube wall is curved, the welding torch tip needs to be moved along the welding area on the tube wall. This operation is manual, inefficient, and the welding quality depends on the operator's skill level, making it difficult to guarantee consistent welding quality. Currently, some methods use a rotating mechanism to clamp the tube. During welding, the operator rotates the tube using this mechanism, while the handheld welding torch remains relatively fixed, making the movement more stable. Although this improves welding quality compared to purely manual methods, it still relies heavily on manual labor, and overall work efficiency remains low. Utility Model Content

Detailed Implementation

[0022] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0023] Reference Figures 1 to 4This utility model provides a circular workpiece welding auxiliary device, including a machine base 1, a rotary welding auxiliary mechanism 2 disposed on the machine base 1, a feeding conveying mechanism 3 disposed on the machine base 1, a discharging conveying mechanism 4 disposed on the machine base 1, and a transfer mechanism 5 disposed on the machine base 1 for transferring the workpiece between the feeding conveying mechanism 3, the discharging conveying mechanism 4, and the rotary welding auxiliary mechanism 2. The feeding conveying mechanism 3 conveys the workpiece to be welded. The transfer mechanism 5 clamps the workpiece from the feeding conveying mechanism 3, moves the workpiece to the rotary welding auxiliary mechanism 2, and performs the welding operation. After welding is completed, the transfer mechanism 5 clamps the workpiece from the rotary welding auxiliary mechanism 2, transfers the workpiece to the discharging conveying mechanism 4, and places the workpiece into the discharging conveying mechanism 4.

[0024] The transfer mechanism 5 includes a first linear module 51 arranged horizontally, a second linear module 52 connected to the first linear module 51, and a rotary clamping assembly 53 for clamping products connected to the second linear module 52. The second linear module 52 is arranged vertically. The first linear module 51 and the second linear module 52 constitute an X-axis and Z-axis moving mechanism, while the feeding conveying mechanism 3 and the discharging conveying mechanism 4 convey materials in the Y-axis direction. Essentially, the above mechanisms cooperate to form a three-axis mechanism.

[0025] The rotary clamping assembly 53 includes a first drive member 531 connected to the second linear module 52, a gripper cylinder 532 connected to the output end of the first drive member 531, and a clamping member 533 (each of the two grippers is connected to a clamping member 533) connected to the output end of the gripper cylinder 532. The contact surface between the clamping member 533 and the workpiece can be matched with the workpiece being processed and is processed into an arc shape. When clamping the workpiece, with the cooperation of the first linear module 51 and the second linear module 52, the clamping member 533 moves to the height corresponding to the workpiece on the feeding conveying mechanism 3 / discharging conveying mechanism 4. Taking the feeding conveying mechanism 3 as an example, when the clamping member 533 reaches the designated position, the feeding conveying mechanism 3 drives the workpiece to move toward the clamping member 533 until the clamping member 533 enters the clamping range of the clamping member 533. Then, the gripper cylinder 532 can drive the clamping member 533 to clamp the workpiece. After the clamping member 533 clamps the workpiece, the second linear module 52 drives the clamping assembly to rise. Then, the first driving member 531 drives the gripper cylinder 532 to rotate 90 degrees, making the workpiece perpendicular to the horizontal plane, which facilitates the placement of the workpiece into the rotary welding auxiliary mechanism 2. In this embodiment, the first driving member 531 is a rotary cylinder.

[0026] The rotary welding auxiliary mechanism includes a rotary chuck 21 for clamping workpieces, a housing 22, a rotating base 23 mounted on the housing 22, a welding torch fixing assembly 24 mounted on the housing 22 for fixing the welding torch, and a drive assembly 25 for driving the rotating base 23. The rotary chuck 21 is connected to the rotating base 23. When the drive assembly 25 drives the rotating base 23 to rotate, the chuck rotates accordingly. The chuck can be a pneumatic chuck or other chuck capable of automatic clamping and releasing. After the transfer mechanism 5 places the workpiece into the rotary chuck 21, the rotary chuck 21 automatically clamps the workpiece (since the components installed on the pipe are not limited to one type, only the pipe is shown in the attached figure). After the workpiece is clamped, the jaws of the gripper cylinder 532 release. If the gripper cylinder 532 will not interfere with the welding process, it can remain stationary. If the gripper cylinder 532 may interfere with the welding process, the second linear module 52 drives the rotary clamping assembly 53 to move above the workpiece.

[0027] The drive assembly 25 includes a second drive member 251, a gearbox 252 connected to the output end of the second drive member 251, and a synchronous pulley 253 connected to the gearbox 252. The synchronous pulley 253 is connected to the rotating base 23. In this embodiment, the second drive member 251 is a motor.

[0028] The welding torch fixing assembly 24 includes a column 241 mounted on the chassis 22, a connecting rod 242 connected to the column 241, a connecting seat 243 connected to the connecting rod 242, and a welding torch fixing bracket 244 connected to the connecting seat 243. The welding torch fixing bracket 244 is used to fix the welding torch. The welding torch fixing bracket 244 and the connecting seat 243 can be configured to be rotatably connected and locked with screws after adjustment. Alternatively, a damping structure can be provided between the welding torch fixing bracket 244 and the connecting seat 243.

[0029] Both the feeding conveying mechanism 3 and the discharging conveying mechanism 4 include a first conveying component 31 and a second conveying component 32 arranged in parallel, and a third driving component 33 for driving the first conveying component 31. The first conveying component 31 and the second conveying component 32 are connected by a transmission shaft 34. In this embodiment, the third driving component 25 is a motor. If there is a need to control the speed during actual operation, a gearbox 252 can also be set with reference to the rotary welding auxiliary mechanism 2. After receiving the workpiece from the previous workstation, each discharging conveying mechanism transports the workpiece to the transfer mechanism 5. The discharging conveying mechanism 4 receives the workpiece from the transfer mechanism 5 and sends the workpiece to the next workstation.

[0030] The first conveying assembly 31 and the second conveying assembly 32 both include a conveying bracket 311, a drive wheel 312 disposed on the conveying bracket 311, and a conveyor belt 313 connected to the drive wheel 312.

[0031] The conveyor belt 313 is provided with a plurality of partitions 314, and the adjacent partitions 314 form a receiving space for accommodating workpieces. In addition, in specific implementation, limiting members can be provided on the conveyor support 311 to limit the two ends of the workpiece.

[0032] The first linear module 51 and the second linear module 52 both include a transfer bracket 511, a lead screw assembly 512 disposed on the transfer bracket 511, and a fourth drive member 513 for driving the lead screw assembly 512. The fourth drive member 513 adopts a motor. The use of a lead screw can precisely control the stroke of the clamping assembly and ensure the accuracy of the transfer.

[0033] In actual operation, the welding torch is first placed in the welding torch holder 244, and the position of the welding torch is adjusted according to the product being processed. The feeding conveyor 3 orderly conveys the workpiece to one side of the transfer mechanism 5. The transfer mechanism 5 clamps the workpiece from the feeding conveyor 3 and rotates it 90 degrees. Then, it moves the workpiece to the chuck of the rotary welding aid and places it in the rotary chuck 21. The drive assembly 25 drives the rotary chuck 21 to rotate, and the welding torch welds the workpiece. After welding, the rotary chuck 21 releases the workpiece, the transfer mechanism 5 clamps the welded workpiece, moves it above the discharge conveyor 4, and rotates it 90 degrees again. Then, the workpiece is placed in the discharge conveyor 4, which then transports the workpiece to the next work station.

[0034] This utility model is equipped with a feeding conveying mechanism 3, a discharging conveying mechanism 4, and a transfer mechanism 5. It can clamp the workpiece and transfer it to the rotary chuck 21 of the rotary welding auxiliary mechanism 2 for clamping. The rotary welding operation is achieved by driving the drive component 25. After welding is completed, the transfer mechanism 5 can also transfer the workpiece to the discharging conveying mechanism 4. The whole process is basically automated, which reduces labor intensity, ensures the consistency of welding quality, and improves the yield.
