Description

Technical Field

[0001] The invention relates to the technical field of speed reducer processing and production, and in particular to an ion arc welding machine for speed reducer manufacturing. Background Art

[0002] In the production and manufacturing of large reducer housings, due to their large size, higher welding strength and precision are required, and ion arc welding can provide a stable arc and concentrated heat, making the weld quality higher and able to withstand greater internal pressure and external loads.

[0003] Large reducers often need to transmit larger torques and bear heavier loads, so it is necessary to weld reinforcing ribs inside the housing to increase the strength of the reducer housing and key parts to prevent deformation or rupture under high loads. Since ion arc welding will produce slag splashing, when the reducer housing is assembled and welded and then the reinforcing ribs are welded, the slag splashing will fall into the reducer housing and accumulate. Before installing parts in the reducer housing, it is necessary to clean the accumulated slag inside, which is inconvenient. Moreover, when the side panels of the large reducer are large in size, when splicing the side panels of the large reducer housing and the base of the large reducer housing, it is necessary to manually align the side panels of the large reducer housing and use tools to fix them, and then weld the side panels of the large reducer housing to the bottom plate of the large reducer housing. In addition, it is necessary to weld the joints between the side panels of the large reducer housing after several side panels of the large reducer housing and the base of the large reducer housing are welded. In this process, it is troublesome to align and fix the side panels and bottom plate of the large reducer housing, which affects the efficiency of reducer manufacturing.

[0018] As described above, the characteristics and advantages of the ion arc welding machine for manufacturing a reducer in the present invention are:

[0019] Through the arrangement of the guide shaft and the connecting shaft, when the cylinder drives the guide shaft to slide into a section of the groove in the guide groove parallel to the bottom plate under the drive of the connecting shaft, the connecting shaft and the guide shaft are simultaneously in a section of the groove in the guide groove parallel to the bottom plate, so that the rotating arm is in a state parallel to the bottom plate, so that the rotating frame fixedly connected to the connecting shaft rotates ninety degrees toward the side close to the rotating base with the connecting shaft as the center of the circle. At this time, the positioning plate 1 and the reducer housing side plate in the telescopic groove are in a vertical state with the reducer housing bottom plate, so that the reducer housing side plate is aligned with the reducer housing bottom plate and is in a fixed state, without the need for the operator to manually align and fix using tools, which simplifies the assembly process of the reducer housing and also facilitates welding when the reducer housing is aligned;

[0020] Through the setting of the telescopic blocks, when the reducer housing is placed between the first positioning plate and the second positioning plate, one of the telescopic blocks first contacts the reducer housing, and the reducer housing slides toward the bidirectional motor under the driving action of the bidirectional motor on the telescopic blocks until both telescopic blocks contact the reducer housing. At this time, the reducer housing is centered under the action of the two synchronously moving telescopic blocks, so that the side of the reducer housing side plate to be welded with the reducer housing base is aligned with the reducer housing base, which is convenient for subsequent welding processing. At the same time, the two telescopic blocks can further fix the reducer housing side plate, thereby improving its stability in the welding reinforcement process;

[0021] By setting the clamping blocks, after the reducer housing base is placed between the two clamping blocks, when the two clamping blocks are in contact with the reducer housing at the same time, since the side of the clamping blocks close to the placement seat is a plane, during the process of the two clamping blocks contacting the reducer housing and gradually approaching the placement seat, the reducer housing is pushed by the clamping blocks, and its edges gradually become parallel to the clamping blocks, and then the two sides close to the clamping blocks are tightly fitted with the clamping blocks. At this time, the two sides of the reducer housing are respectively facing the two housing splicing components, and the fixing effect of the reducer housing is achieved while quickly positioning, which is not only convenient for cooperation with the housing splicing components, but also convenient for welding the housing in a stable state;

[0022] By cooperating with the rotating base and the telescopic block, when the unwelded reducer housing side panel enters between the two welded reducer housing side panels under the pushing action, since the reducer housing side panels have the same height, the positioning plate 2 will not interfere in this process. When the unwelded reducer housing side panel completely enters between the two welded reducer housing side panels, the positioning plate 2 and the reducer housing base still have a certain clamping effect on the reducer housing side panel, thereby improving the stability of the reducer housing side panel in subsequent welding work, facilitating operation and improving welding accuracy.

[0044] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows:

[0045] The initial state is:

[0046] The guide shaft 303 is located at the bottom of the guide groove 302, the rotating arm 304 is in a vertical state, the opening of the rotating frame 306 is vertically upward, the limit blocks 309 on both sides of the positioning plate 307 are at the highest point in the limit groove 308, the spring 1 314 contracts, so that the telescopic rod 312 is completely retracted into the telescopic groove 311, so that the positioning plate 2 313 and the support arm 310 are in a conflicting state, the bidirectional motor 401 is not started, the two sliding seats 404 are respectively on both sides of the rotating frame 306, the spring 2 408 is extended, so that the telescopic block 407 extends out of the storage groove 406, the motor 510 is not started, the reducer housing is not placed between the clamping blocks 506, and the rotating rod 511 is parallel to the connecting plate 1 505.

[0047] The working status is:

[0048] Insert the reducer housing between the two clamps 506:

[0049] When welding, first place the bottom plate or top plate of the reducer housing flat on the top of the placement seat 507 so that it is located between the two clamping blocks 506, and then start the motor 510 so that the motor 510 drives the rotating rod 511 on the output shaft to rotate, so that the rotating rod 511 drives the first rotating seats 512 on both sides to move in an arc with the motor 510 as the center. When the first rotating seat 512 moves, the second rotating seat 514 is pulled by the pulling rod 513, so that the second rotating seat 514 drives the connecting plate 1 505 to slide toward the placement seat 507 under the pulling action, so that the clamping block 506 on the top of the connecting plate 1 505 slides toward the placement seat 507. When the two clamps 506 are in contact with the reducer housing at the same time, since the side of the clamps 506 close to the placement seat 507 is a plane, in the process of the two clamps 506 contacting the reducer housing and gradually approaching the placement seat 507, the reducer housing is pushed by the clamps 506 and its edges gradually become parallel to the clamps 506, and then the two sides close to the clamps 506 are tightly fitted with the clamps 506. At this time, the two sides of the reducer housing are respectively facing the two housing splicing components, which can achieve the fixing effect of the reducer housing while quickly positioning it, which is not only convenient for cooperation with the housing splicing components, but also convenient for welding the housing in a stable state.

[0050] Place the side panels of the reducer housing onto the support arm 310:

[0051] After the bottom plate in the reducer housing is placed, the side wall housing of the reducer housing to be assembled is placed into the two housing splicing components respectively. First, the edges of the reducer housing side plate and the reducer housing bottom plate that need to be welded are fitted with the positioning plate 1 307, and then placed on the support arm 310. During the placement process, the positioning plate 2 313 is pulled to the side away from the positioning plate 1 307, so that the positioning plate 2 313 pulls the telescopic rod 312 to slide out of the telescopic groove 311, thereby extending the spring 1 314 fixedly connected to the telescopic rod 312. After the reducer housing is placed on the support arm 310, the positioning plate 2 313 is released, so that the spring 1 314 is reset to drive the telescopic rod 312 to retract and telescope. The groove 311 drives the second positioning plate 313 to move toward the side close to the positioning plate 1 307, so that the second positioning plate 313 presses against the side of the reducer housing away from the positioning plate 1 307, and then fixes the reducer housing with the cooperation of the positioning plate 1 307 and the second positioning plate 313. At this time, the reducer housing is placed horizontally, which is convenient for the staff to weld the reinforcing ribs to the fixed reducer housing, and when the reinforcing ribs are welded in this state, there is no obstruction on the edge of the reducer housing, and the slag spatter generated during the ion arc welding process is easy to clean, thereby avoiding the situation that the slag spatter generated when the reinforcing ribs are welded after the reducer housing is assembled will fall into the reducer housing and is difficult to clean.

[0052] Align the reducer housing side plate with the reducer housing base:

[0053] After the side plate of the reducer housing is fixed between the positioning plate 1 307 and the positioning plate 2 313, the bidirectional motor 401 is started, so that the bidirectional motor 401 drives the screw rods 402 on both sides to rotate, so that the two screw rods 402 drive the sliding seat 404 to slide to the side close to the bidirectional motor 401, and then drive the clamping seats 405 on the top of the two sliding seats 404 to slide toward the reducer housing, so that the telescopic blocks 407 on the top of the two clamping seats 405 contact the reducer housing. When the reducer housing is not centered, one of the telescopic blocks 407 first contacts the reducer housing. After the reducer housing contacts, the reducer housing slides toward the bidirectional motor 401 under the driving action of the bidirectional motor 401 on the telescopic block 407 until the two telescopic blocks 407 are in contact with the reducer housing. At this time, the reducer housing is centered under the action of the two synchronously moving telescopic blocks 407, so that the side of the reducer housing side plate to be welded to the reducer housing base is aligned with the reducer housing base, which is convenient for subsequent welding processing. At the same time, the two telescopic blocks 407 can further fix the reducer housing side plate to improve its stability in the welding reinforcement process.

[0054] Assemble the reducer housing side panels onto the reducer housing base:

[0055] After the reinforcement ribs on the side plate of the reducer housing are welded, the cylinder 315 is started, so that the cylinder 315 pushes the push block 316 through the output shaft, thereby driving the connecting shaft 305 to move in the direction close to the rotating base 2, and then the connecting shaft 305 drives the rotating arm 304 and the guide shaft 303 to rotate with the initial position of the lower part of the guide groove 302 as the center point. At this time, the upper end of the rotating arm 304 and the connecting shaft 305 move to the side close to the rotating base 2. After the rotating arm 304 rotates to a certain angle, since the position of the cylinder 315 is fixed, the cylinder 315 continues to push the push block 316 through the output shaft, so that the connecting shaft 305 continues to drive the upper end of the rotating arm 304 to move toward the rotating base 2. At this time, the rotating arm 304 continues The guide shaft 303 is pulled and driven to slide upward in the guide groove 302. Therefore, the guide shaft 303 moves upward in the guide groove 302 during the movement of the connecting shaft 305, so that the connecting shaft 305 moves vertically in the guide groove 302 during the process of horizontally approaching the rotating base 2. At this time, the rotating arm 304 between the connecting shaft 305 and the guide shaft 303 changes from vertically downward to gradually inclined, so that the connecting shaft 305 drives the rotating frame 306 to rotate and tilt. In the process of further movement of the connecting shaft 305 causing the tilt angle of the rotating arm 304 to gradually increase, the tilt angle of the rotating frame 306 increases synchronously, thereby driving the reducer side plates in the positioning plate 1 307 and the positioning plate 2 313 to gradually tilt. The rotating frame 306 is gradually approached to the rotating base 2. When the guide shaft 303 slides into a groove at the top of the guide groove 302 parallel to the bottom plate 1 driven by the connecting shaft 305, the connecting shaft 305 and the guide shaft 303 are simultaneously in a groove in the guide groove 302 parallel to the bottom plate 1. The guide shaft 303 and the connecting shaft 305 are at the same height, so that the rotating arm 304 is parallel to the bottom plate 1. In the process of the rotating arm 304 tilting from vertical downward and finally rotating to be parallel to the bottom plate 1, the rotating frame 306 fixedly connected to the connecting shaft 305 rotates 90 degrees to the side close to the rotating base 2 with the connecting shaft 305 as the center. At this time, the positioning plate 1 307 and the reducer housing side plate clamped in the telescopic groove 311 are The edge of the reducer housing bottom plate fixed on the top of the rotating base 2 is in a vertical state. When the cylinder 315 further pushes the connecting shaft 305 through the push block 316, the positioning plate 1 307 rotated ninety degrees will contact the reducer housing base, so that the positioning plate 1 307 is squeezed and retracted into the rotating frame 306. Then the bottom of the reducer housing side plate contacts the reducer housing bottom plate and is fixed to the edge of the reducer housing bottom plate under the action of the two telescopic blocks 407 and the positioning plate 2 313. At this time, the reducer housing side plate is aligned with the reducer housing bottom plate and is in a fixed state. There is no need for the operator to manually align and use tools to fix it. This simplifies the reducer housing assembly process while facilitating welding when the reducer housing is aligned.

[0056] Switch the direction of the reducer housing base and continue welding:

[0057] After both sides of the reducer housing base are welded, all components are driven to reset. At this time, two reducer housing side panels have been welded on the reducer housing bottom plate. Then, the reducer housing is rotated ninety degrees, and the motor 510 is started, so that the two clamping blocks 506 slide toward the reducer housing base, and clamp the reducer housing from both sides where the reducer housing side panels have been welded, so as to fix the reducer housing base again, so that the two sides of the reducer housing side panels that are not welded on the reducer base are aligned with the two housing splicing components, and the positioning plate 1 307, the positioning plate 2 313 and the telescopic block 407 are used again to fix the reducer housing side panels to be welded, and the reinforcement welding operation is performed. After the welding is completed, the cylinder 315 is started. The side panels of the reducer housing to be welded, which are clamped in the positioning plate 1 307 and the positioning plate 2 313, are erected and gradually moved toward the two sides of the reducer housing base to be welded. At this time, since two reducer housing side panels have been welded on the reducer housing base, and the width of the two reducer housing side panels to be welded is the same as the spacing between the two welded reducer side panels, the telescopic blocks 407 are located on both sides of the reducer housing side panels to be welded when the rotating frame 306 rotates 90 degrees and approaches the reducer housing base. The telescopic blocks 407 will contact the welded side panels and be squeezed by the welded reducer housing side panels, so that the telescopic blocks 407 slide into the storage slots 406. During the process of entering the receiving groove 406, the reducer housing side plate to be welded is continuously pushed by the support arm 310 fixedly connected to the rotating frame 306, and gradually slides between the two welded reducer housing side plates. When the telescopic block 407 is completely retracted into the receiving groove 406, the positioning plate 1 307 is also retracted into the rotating frame 306 under the pressure of the reducer housing base. Since the reducer housing side plates have the same height, the positioning plate 2 313 will not interfere in this process. Therefore, when the support arm 310 pushes the reducer housing side plate to be welded between the two welded reducer housing side plates, the clamping structure of the reducer housing side plate to be welded automatically shrinks and will not interfere with the reducer housing base and The two welded reducer housing side panels interfere with each other. When the unwelded reducer housing side panel completely enters between the two welded reducer housing side panels, the two welded reducer housing side panels have a certain clamping effect on the reducer housing side panels to be welded. At this time, the positioning plate 2 313 located on the top of the reducer housing side panel to be welded still has a downward pressing effect on the top of the reducer housing side panel to be welded under the contraction of the spring 1 314, thereby cooperating with the fixed clamped reducer housing base to produce a clamping effect on the reducer housing side panel to be welded, thereby improving the stability of the reducer housing side panel in subsequent welding work, facilitating operation and improving welding accuracy.
