Description

Technical Field

[0001] The present invention relates to the technical field of commutator segments, and in particular to a safety auxiliary device for commutator segment production. Background Art

[0002] Commutator segments are key components used in motors and generators to convert alternating current (AC) to direct current (DC). During the production process, safety equipment may be required, especially during welding and surface treatment, to ensure worker safety and product quality. Spot welding involves welding the two sides of the commutator segments together to form a commutator segment assembly.

[0003] In the prior art, when spot welding commutator segments, due to the high degree of precision required, workers are usually required to manually align the commutator shaft with the clamping point, and then use a positioning sensor to determine the welding position before welding. However, if the positioning sensor fails and the equipment is mistakenly turned on, the worker is too close to the equipment at this time. The impact force of the welding can easily hit the commutator segment towards the worker, endangering his personal safety.

[0004] In addition, during welding, the welding needle usually contacts the workpiece and the welding material, and the welding area is heated by electric current to fuse the welding material and the workpiece together to form a welded joint. However, after each welding is completed, the welding material is easily adhered to the vicinity of the welding needle, making it easy to melt the remaining welding material together during the next welding, causing overflow at the welding point. After cooling and solidification, there will be obvious bulges in the welding point area, which makes it difficult to polish later.

[0020] 2. Through the arrangement of arc-shaped semicircular blocks and alloy leaf springs, when the semicircular blocks come into contact with the steering shaft, the mutual squeezing force between the multiple semicircular blocks, combined with the squeezing method of the alloy leaf springs toward the axis, can effectively clamp the commutator shaft in the center. In addition, the elastic force of the alloy leaf springs and the arc-shaped surface of the semicircular blocks can prevent the shaft from being scratched during clamping, thereby improving the clamping effect.

[0021] 3. Through the setting of the telescopic material removal mechanism, when the telescopic plate moves toward the direction of the welder, the bottom of the pressure plate is polished by the grinding brush to make its bottom flat, and the unsolidified welding material remaining at the bottom of the welding needle is brushed off by the silicon carbide brush. Combined with the setting of the open groove and the pocket box, the open groove can prevent the residue from falling from the side to the bottom working area during the brushing process. The pocket box can collect the residue falling from the end of the brush head when the telescopic plate is retracted, and recycle it to avoid the residual welding material melting during welding, resulting in overflow of the welding point, which increases the difficulty of grinding.

[0046] Further examples:

[0047] Please refer to Figure 1 、 Figure 3 、 Figure 8 and Figure 9 As shown, the telescopic removal mechanism 7 includes a rack plate 74 fixedly connected to the top of the sliding plate 66, the top of the rack plate 74 is meshed with a gear 710, and the center of the gear 710 is fixedly connected to a one-way threaded rod 73. The one-way threaded rod 73 rotates through the top of the support plate 610 away from the side of the gear 710, and the outer wall of the one-way threaded rod 73 away from the gear 710 is threadedly connected to the telescopic plate 71;

[0048] The telescopic material removal mechanism 7 also includes a material pocket box 75 fixedly connected to the edge of the telescopic plate 71. An open groove 79 is formed on the side of the telescopic plate 71 away from the support plate 610. A silicon carbide brush 77 is fixedly connected to one side of the inner wall of the telescopic plate 71, and a grinding brush 78 is fixedly connected to the other side of the inner wall of the telescopic plate 71.

[0049] A welding needle 72 is fixedly mounted on the bottom of the welding device 5, and a pressure plate 76 is slidably connected to the outer wall of the bottom of the welding needle 72;

[0050] The material pocket box 75 is located below the silicon carbide brush 77 and the grinding brush 78, and the width of the material pocket box 75 is consistent with the width of the open groove 79;

[0051] The silicon carbide brush 77 corresponds to the position of the welding needle 72 , the grinding brush 78 corresponds to the position of the pressing plate 76 , and both the silicon carbide brush 77 and the grinding brush 78 are located in the middle of the open groove 79 .

[0052] The effects achieved by this embodiment are as follows: In the prior art, after each welding is completed, welding material is easily adhered near the welding needle 72, making it easy to melt the remaining welding material together during the next welding, causing overflow at the welding point. After cooling and solidification, there will be obvious bulges in the welding point area, which makes it difficult to grind later. Compared with the prior art, through the implementation of this embodiment, a telescopic material removal mechanism 7 is set to be able to grind the bottom of the pressure plate 76 through the grinding brush 78 when the telescopic plate 71 moves toward the welder 5 to make its bottom flat, and the unsolidified welding material remaining at the bottom of the welding needle 72 is brushed off by the silicon carbide brush 77. In combination with the setting of the open groove 79 and the material pocket box 75, the open groove 79 can collect residues during the brushing process to prevent residues from falling from the side to the bottom working area.

[0053] The complete usage steps and working principle of the above embodiment are as follows:

[0054] In the initial state, the two clamping plates 613 are at positions away from each other, the telescopic plate 71 is at a position away from the welder 5, and the return spring 611 and the semicircular block 614 are both in a naturally relaxed state.

[0055] When in use, first place the commutator between the two trapezoidal blocks 62, with the part of the commutator segment to be welded facing one side of the welder 5, then start the electric push rod 64 through the external control system, and the electric push rod 64 pushes the U-shaped frame 65 to move toward the welder 5. When the U-shaped frame 65 moves, it can synchronously push the sliding plate 66 and the rear bracket 63 to move. When the sliding plate 66 moves, it can drive the connecting column 612 and the clamping plate 613 to move synchronously as a whole. Since the adjustment blocks 67 are symmetrically arranged and the sides close to each other are set to be equal, the adjustment blocks 67 are symmetrically arranged and the sides close to each other are set to be equal. The waist trapezoidal plate, so the two connecting columns 612 are squeezed close to each other when they contact the adjustment block 67, and the distance of closeness can be adjusted according to the size of the commutator segment. The position of the adjustment block 67 is then adjusted, and the semicircular block 614 on the clamping plate 613 and the commutator shaft are squeezed against each other. Since the outer wall of the semicircular block 614 is provided with an alloy leaf spring 617, and the alloy leaf spring 617 and the semicircular block 614 are distributed along the arc of the arc groove 618, the commutator shaft can be clamped in the center under the elastic force of the alloy leaf spring 617, and can be To prevent the shaft from being scratched, the rear bracket 63 is pushed to move by the electric push rod 64, and the top trapezoidal block 62 and the commutator segments are pushed together to the position of the shaft clamp 3, so that the shaft is clamped during the movement, which can prevent the commutator segments from slipping due to inertia. The shaft is clamped in the center so that its end can smoothly enter the shaft clamp 3. At this time, the clamping plate 613 has reached the edge of the adjustment block 67. Therefore, under the elastic force of the reset spring 611, the clamping plate 613 returns to its initial state and disengages from the shaft, while the shaft has been clamped by the shaft clamp 3, starting. The welder 5 moves downward to perform spot welding, and then cooperates with the external drive motor to drive the rotating column 4 to rotate and change the spot welding position. During the feeding process of the commutator segments, the adjustment block 67 is used to achieve the effect of intermittent clamping, automatically feeding the commutator segments to the points without the need for manual alignment by employees, which can improve safety. If the size of the commutator segments changes, the hand wheel 69 can be turned to drive the bidirectional threaded rod 616 to rotate, so that the distance between the adjustment blocks 67 is moved away from or closer to each other to adapt to different sizes. The limit plate 68 can keep the adjustment block 67 moving smoothly.

[0056] Please refer to the above working process Figures 1 to 7 .

[0057] Furthermore, when the sliding plate 66 moves toward one side of the welder 5, it can synchronously drive the rack plate 74 to move. After the rack plate 74 engages the gear 710, the gear 710 drives the one-way threaded rod 73 to rotate. Since the telescopic plate 71 is threadedly connected to the outer wall of the one-way threaded rod 73, the rotation of the one-way threaded rod 73 can drive the telescopic plate 71 to move toward the welder 5. When the telescopic plate 71 moves, it drives the grinding brush 78 and the silicon carbide brush 77 to move synchronously toward the pressure plate 76 and the welding needle 72. The bottom of the pressure plate 76 is polished by the grinding brush 78 to make its bottom flat, and the unsolidified welding material remaining at the bottom of the welding needle 72 is brushed away by the silicon carbide brush 77. In combination with the arrangement of the open groove 79 and the material pocket box 75, the open groove 79 can prevent the residue from falling from the side to the bottom working area during the brushing process, and the material pocket box 75 can collect the residue falling from the end of the brush head when the telescopic plate 71 is retracted for recycling, which can effectively prevent the residual welding material from melting during welding and causing overflow of the welding point;

[0058] Please refer to the above working process Figure 1 、 Figure 3 and Figures 8 and 9 .

[0059] Summary: Through the setting of the auxiliary positioning mechanism 6, during the feeding process of the commutator segments, the setting of the isosceles trapezoidal plate on the side where the two adjustment blocks 67 are close to each other can be used, and the clamping plate 613 can be used to achieve the effect of intermittent clamping, and automatically assist in the point-to-point feeding of the commutator segments without the need for manual alignment by employees. Secondly, through the setting of the telescopic removal mechanism 7, when the telescopic plate 71 moves toward the direction of the welder, the bottom of the pressure plate is polished by the grinding brush 78 to make its bottom flat, and the unsolidified welding material remaining at the bottom of the welding needle is brushed off by the silicon carbide brush 77. In combination with the setting of the open groove 79 and the material pocket box 75, the open groove 75 can prevent residue from falling from the side to the bottom working area during the brushing process, and the material pocket box 79 can collect the residue falling from the end of the brush head when the telescopic plate is retracted for recycling.
