Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of welding-related technologies, and more specifically, to a high-precision electric welding machine for the production of metallurgical continuous casting equipment parts. Background Technology

[0002] In the production of parts for metallurgical continuous casting equipment, rotary joints are key components, and the welding accuracy of their lugs directly affects the operational stability of the equipment. Currently, welding the four lugs on a rotary joint typically relies on manual placement and positioning before welding, a method that presents significant technical bottlenecks.

[0003] When manually placing the lugs, operators rely on experience to adjust the angle and spacing, making it difficult to precisely control the symmetry and spatial position of the four lugs. This results in significant deviations in the assembly accuracy of the lugs and rotary joint after welding, often leading to problems such as axial misalignment and angular errors, which in turn cause vibration or seal failure during rotary joint operation. Furthermore, manual operation is significantly affected by operator skill and fatigue, resulting in large variations in welding quality between different batches of products, high rework rates, and severely restricting production efficiency.

[0004] Furthermore, manual welding operations are inefficient, requiring multiple positioning adjustments for each set of lugs, which cannot meet the demands of large-scale production. As metallurgical continuous casting equipment develops towards higher speeds and greater precision, traditional manual welding methods can no longer meet the high-precision assembly requirements of rotary joints. There is an urgent need to develop high-precision welding equipment with automatic positioning functions to solve the problem of insufficient precision caused by manual operation, and to improve the consistency of welding quality and production efficiency. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a high-precision electric welding machine for the production of metallurgical continuous casting equipment parts. This solves the technical problem in the prior art where, when manually placing ear plates, operators need to rely on experience to adjust the angle and spacing of the ear plates, making it difficult to accurately control the symmetry and spatial position of the four ear plates. This results in a large deviation in the assembly accuracy of the ear plates and the rotary joint after welding, often leading to problems such as axis offset and angle error.

[0006] According to one aspect, at least one embodiment of this disclosure provides a high-precision electric welding machine for the production of metallurgical continuous casting equipment parts, comprising:

[0007] A base plate and a frame, wherein the frame is fixed to the base plate;

[0008] A loading rack and a conveying and positioning assembly, wherein the loading rack is fixed to the bottom of the frame body and the conveying and positioning assembly is disposed on the loading rack and the frame body;

[0009] A rotation adjustment assembly is mounted on the frame.

[0010] The welding machine body consists of a pair of columns and welding components. The welding machine body is fixed to the surface of the base plate, the columns are fixed to the frame, and the welding components are mounted on the columns.

[0011] The conveying and positioning assembly includes a pair of side plates, both of which are disposed on the surface of the feeding rack. The surface of the feeding rack has an elongated cavity, and a drive screw is disposed inside the elongated cavity. The drive screw is rotated by a motor, and a pusher is connected to the drive screw by a threaded connection. The pusher slides against the inner wall of the elongated cavity.

[0012] As a further technical solution, a swing arm is rotatably connected to the bottom of the frame. The swing arm is rotated by a motor. A crossbeam is provided at the upper end of the swing arm, and a control screw is rotatably connected inside the crossbeam.

[0013] As a further technical solution, the control screw is rotated by a motor, a guide rod is provided inside the cross frame, and both ends of the control screw are connected to claws by threaded engagement, with the claws slidingly fitted to the guide rod.

[0014] As a further technical solution, the rotation adjustment assembly includes a base support, which is fixed to the surface of the base plate. A drive motor is provided at the bottom of the base support, and a rotating seat is provided at the output end of the drive motor.

[0015] As a further technical solution, the welding assembly includes a pair of welding heads, both of which are disposed on the column. The surface of the column is provided with side grooves, and a vertical screw and a vertical rod are respectively disposed in the pair of side grooves.

[0016] As a further technical solution, the vertical screw is rotated by a motor, and a connecting rod is connected to the vertical rod. The connecting rods are fixedly connected to each other, and the welding heads rotate one end of the connecting rod by a pin.

[0017] As a further technical solution, the width of the opening at the top of the elongated cavity is smaller than the thickness of the ear plate.

[0018] As a further technical solution, a pair of telescopic cylinders are provided on the surface of the frame, and each telescopic cylinder has a sleeve at its output end.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. In this disclosure, the conveying and positioning component achieves automatic conveying of ear plates through the cooperation of the drive screw and the pusher frame, avoiding errors caused by manual placement. The side plate guides the ear plates to ensure accurate conveying path. The rotation adjustment of the swing arm and the crossbeam enables the claws to accurately clamp the ear plates and fit against the rotary joint. The control screw and guide rod drive the claws to close synchronously, accurately controlling the angle and spacing of the ear plates. This solves the problem of difficulty in controlling symmetry and spatial position by manual operation, achieving precise positioning of the four ear plates, improving the assembly accuracy of the ear plates and rotary joint after welding, reducing axial offset and angular errors, reducing quality dispersion caused by human experience, improving product consistency, and avoiding multiple manual positioning adjustments, thus improving production efficiency.

[0021] 2. In this disclosure, the vertical screw and vertical rod of the welding assembly enable synchronous lifting and lowering of the welding head. The pin connection allows for fine-tuning of the welding head's angle to adapt to different weld requirements. The simultaneous operation of the two welding heads reduces welding time per station and improves welding efficiency. The drive motor of the rotation adjustment assembly drives the rotary seat to rotate precisely, allowing the rotary joint to switch to different welding positions, achieving multi-angle welding within a 360° range. No manual adjustment of the workpiece posture is required. In conjunction with the welding assembly, the continuous welding of the four ear plates is completed, ensuring the consistency of the welding angle and position of each ear plate and avoiding positioning deviations caused by manual workpiece rotation. At the same time, the telescopic cylinder and the sleeve fix the rotating structure to prevent workpiece displacement during welding, further ensuring welding accuracy and meeting the high-precision welding requirements of metallurgical continuous casting equipment accessories.

[0034] like Figures 1-4 As shown, it illustrates a high-precision welding machine for producing metallurgical continuous casting equipment parts according to an embodiment of this disclosure, comprising:

[0035] The base plate 1 and the frame 2 are fixed on the base plate 1;

[0036] The feeding rack 3 and the conveying and positioning component 6 are provided. The feeding rack 3 is fixed to the bottom of the frame 2, and the conveying and positioning component 6 is provided on the feeding rack 3 and the frame 2.

[0037] Rotation adjustment component 7 is disposed on the frame 2;

[0038] The welding machine body 4, a pair of columns 5, and welding components 8 are provided. The welding machine body 4 is fixed to the surface of the base plate 1, the columns 5 are all fixed to the frame 2, and the welding components 8 are arranged on the columns 5.

[0039] The conveying and positioning assembly 6 includes a pair of side plates 6-1, both of which are disposed on the surface of the feeding rack 3. The surface of the feeding rack 3 has an elongated cavity 6-2, and a drive screw 6-3 is disposed in the elongated cavity 6-2. The drive screw 6-3 is rotated by a motor. A pusher frame 6-4 is threadedly connected to the drive screw 6-3. The pusher frame 6-4 slides against the inner wall of the elongated cavity 6-2. A swing arm 6-5 is rotatably connected to the bottom of the frame 2. The swing arm 6-5 is rotated by a motor. A crossbeam 6-6 is disposed at the upper end of the swing arm 6-5. A control screw 6-7 is rotatably connected to the crossbeam 6-6. The control screw 6-7 is rotated by a motor. A guide rod 6-8 is disposed in the crossbeam 6-6. Both ends of the control screw 6-7 are threadedly connected to claws 6-9. The claws 6-9 are slidably fitted with the guide rods 6-8.

[0040] In some examples, during the welding process of metallurgical continuous casting equipment parts production, a conveying and positioning component 6 is designed to achieve continuous conveying and precise positioning of ear plates. This component is guided by a pair of side plates 6-1 fixed to the surface of the loading rack 3. A drive screw 6-3 is installed in the long cavity 6-2 inside the loading rack 3. When the motor drives the screw 6-3 to rotate, it drives the pusher 6-4 to slide along the inner wall of the long cavity 6-2 through threaded engagement, pushing the stacked ear plates one by one to the designated position. The swing arm 6-5 at the bottom of the frame 2 is controlled by a motor to rotate, which can adjust the upper crossbar 6-6 above the ear plates. The two ends of the control screw 6-7 inside the crossbar 6-6 are connected to the claws 6-9 through reverse threads. When the control screw 6-7 rotates, the claws 6-9 on both sides close synchronously along the guide rod 6-8, precisely clamping the ear plates and then fitting them against the surface of the rotary joint after the swing arm 6-5 rotates, thus completing the positioning.

[0041] By driving the screw 6-3 to push, adjusting the angle of the swing arm 6-5, and synchronously clamping the jaws 6-9, the conveying and positioning assembly 6 realizes the function of continuous conveying of the ear plate and direct contact with the rotary joint, providing stable workpiece positioning for the welding process.

[0042] like Figures 1-4 As shown in the figure, the rotation adjustment component 7 proposed in this embodiment includes a base 7-1, the base 7-1 is fixed on the surface of the base plate 1, a drive motor 7-2 is provided at the bottom of the base 7-1, and a rotating seat 7-3 is provided at the output end of the drive motor 7-2.

[0043] In some examples, to meet the multi-directional welding requirements of continuously cast parts, a rotation adjustment assembly 7 was designed. This assembly is supported by a base support 7-1 fixed to the surface of the base plate 1. The rotating seat 7-3 at the output end of the bottom drive motor 7-2 is rotatably connected to the base support 7-1 via bearings. A rotary joint and workpiece can be installed on the rotating seat 7-3. When the drive motor 7-2 starts, it drives the rotating seat 7-3 to rotate precisely, allowing the workpiece to switch to different welding positions without the need for manual adjustment of the workpiece posture. This structure enables 360° switching of welding positions through the motor-driven rotating seat 7-3. Combined with the welding assembly 8, it can continuously weld multi-angle joints of the workpiece, improving welding efficiency and accuracy.

[0044] like Figures 1-4 As shown in the figure, the welding assembly 8 in this embodiment includes a pair of welding heads 8-1, each of which is mounted on the column 5. The surface of the column 5 is provided with a side groove 8-2. A vertical screw 8-3 and a vertical rod 8-4 are respectively installed in the pair of side grooves 8-2. The vertical screw 8-3 is rotated by a motor. A connecting rod 8-5 is connected to the vertical screw 8-3 and the vertical rod 8-4. The connecting rod 8-5 is fixedly connected to each other. The welding heads 8-1 rotate one end of the connecting rod 8-5 by means of a pin.

[0045] In some examples, a welding assembly 8 is designed to improve production efficiency by enabling synchronous welding at two workstations. A pair of welding heads 8-1 of this assembly are respectively installed in the side grooves 8-2 of the column 5. The vertical screw 8-3 in the side groove 8-2 is driven to rotate by a motor. Through threaded engagement, it drives the connecting rod 8-5 to move up and down along the vertical rod 8-4, realizing the synchronous lifting and lowering of the two welding heads 8-1. The welding heads 8-1 are rotatably connected to the connecting rod 8-5 through a pin, which can finely adjust the welding angle to adapt to the tilt requirements of different welds. When the workpiece is switched from the rotation adjustment assembly 7 to the welding position, the two welding heads 8-1 move synchronously to the specified height and perform welding operations at the same time, reducing the waiting time for single-station welding.

[0046] Through the synchronous drive of the vertical screw 8-3, the angle adjustment of the pin shaft, and the coordinated operation of the two welding heads 8-1, the welding assembly 8 realizes the synchronous movement and welding function of the two welding heads 8-1, which greatly improves the welding efficiency and consistency of metallurgical parts.

[0047] For example, such as Figure 3 As shown, the width of the top opening of the long cavity 6-2 is smaller than the thickness of the ear plate.

[0048] In some examples, a smaller opening size is used to prevent the earplate from getting stuck in the long cavity 6-2 during movement.

[0049] For example, such as Figure 1 As shown, a pair of telescopic cylinders 9 are provided on the surface of the frame 2, and each of the telescopic cylinders 9 is provided with a sleeve 10 at its output end.

[0050] In some examples, by providing a telescopic cylinder 9 and a sleeve 10, the rotating structure can be fixed during the welding process to prevent displacement.

Rod 8-3 and vertical rod 8-4 are connected. Welding head 8-1 is rotatably connected to connecting rod 8-5 via a pin. Telescopic cylinder 9 is fixed to the surface of frame 2. Sleeve 10 is installed at the output end of telescopic cylinder 9. Start drive screw 6-3 motor. Pusher 6-4 pushes ear plates in long cavity 6-2 one by one to the designated position. Swing arm 6-5 motor drives swing arm 6-5 to rotate. Horizontal frame 6-6 moves above ear plate. Control screw 6-7 motor drives chuck 6-9 to close and clamp ear plate. Swing arm 6-5 rotates to attach ear plate to rotary joint. Rotation adjustment component 7 drive motor 7-2 drives rotary seat 7-3 to rotate, so that rotary joint switches welding position.
