Description

Technical Field

[0001] The invention relates to the technical field of gear inner wall processing rollers, and in particular to a gear inner wall processing roller and a production device thereof. Background Art

[0002] In the production and processing of gears, the processing of the inner wall of the gear is of great importance. At present, there are some problems in the use of the existing gear inner wall processing roller.

[0003] On the one hand, when the traditional gear inner wall processing roller is processing the gear inner wall, the debris generated is easy to enter the gear hole, which not only affects the processing accuracy, but also causes serious wear on the surface of the processing roller. As the processing progresses, the wear continues to increase, which not only reduces the service life of the processing roller, but also requires frequent replacement of the processing roller, increasing production costs and production time.

[0004] On the other hand, the existing processing roller is usually an integrated structure. When the size of the inner wall of the gear changes, the entire processing roller needs to be replaced, which undoubtedly increases the cost investment. Moreover, the integrated processing roller is also inconvenient in storage and transportation and occupies a large space.

[0005] In addition, in the production process of the processing roller, the traditional production method often requires manual installation of bolts one by one to splice the processing part and the main part together. This method is not only inefficient, but also prone to loose installation, affecting the quality and performance of the processing roller. At the same time, manual operation is also easily affected by human factors, resulting in poor consistency and stability in production.

[0006] Therefore, it is necessary to design a gear inner wall processing roller and a production device thereof to solve the above problems. Summary of the invention

[0017] The present invention has the following beneficial effects:

[0018] 1. Compared with the prior art, the processing roller is provided with an annular opening on the hollow plate. When processing the inner wall of the gear, the annular opening will continuously blow air into the gaps between the teeth of the processing roller, and quickly blow out the debris generated during processing, thereby avoiding the situation in which the residue of the debris causes excessive wear between the roller body and the gear, resulting in a shortened service life of the roller body, and at the same time, the accuracy of the processing of the inner wall of the gear can be ensured;

[0021] 4. Compared with the prior art, in the process of producing the processing roller, the processing part is driven to rotate by the rotary alignment assembly, so that the threaded holes on the hollow plate are aligned with the threaded holes on the fixed plate, so that the subsequent bolts can stably enter the corresponding two threaded holes to connect the main part of the processing roller and the processing part together;

[0022] 5. Compared with the prior art, through the setting of the limit assembly, after the position of the processing part is adjusted, the downward movement of the processing table will drive the limit block and the card to move in the direction close to the first gear, thereby limiting the first gear and avoiding the rotation of the fixed plate due to the vibration of the equipment during the processing, which may cause the threaded hole to be misaligned.

[0023] In summary, the gear inner wall processing roller and its production device of the present invention have significant advantages. First, when processing the inner wall of the gear, the annular opening on the hollow plate of the processing roller blows air into the gap between the teeth to quickly blow out debris, thereby avoiding excessive wear of the roller body and the gear caused by residual debris, ensuring processing accuracy, and extending the service life of the roller body. Secondly, the processing part is integrally formed and can be processed after installation, and when the radius of the gear hole changes, only the processing part needs to be replaced, reducing production costs. In terms of production equipment, the tightening assembly and the placement table can automatically screw multiple bolts into the threaded holes of the hollow plate and the fixed plate to realize the automated production of the processing roller. The rotating alignment assembly can drive the processing part to rotate so that the threaded holes are aligned, which is convenient for bolting the main part and the processing part. In addition, after the position of the processing part is adjusted, the limit assembly can avoid the rotation of the fixed plate and the misalignment of the threaded holes due to equipment vibration, thereby ensuring stable processing.

[0038] The functional principle of the present invention can be explained through the following operation mode: during the use of the processing roller, a suitable processing part is selected according to the radius of the inner wall of the gear hole, and then the processing part is connected to the main part by using multiple bolts 6. After the fixing frame 4 is fixed in a suitable position by multiple fixing screws 12, the rotating shaft 7 is connected to the existing feeding device, and the connecting pipe 11 is connected to the air outlet of the existing fan, so that the inner wall of the gear can be processed. During the processing, the fan is in a running state, so as to blow out the debris generated during the processing;

[0039] In the process of processing roller production, after the main part and the processing part are produced separately, the processing part is placed in the square groove so that the hollow plate 2 is located above the roller body 1. The staff controls the two second pneumatic rods 23 to stretch, drive the two positioning blocks 22 to move relatively, clamp the processing part, and then place the main part on the placement table 17 so that the fixing frame 4 is located in the placement groove 26. At the same time, the two cross tubes 9, the rotating shaft 7 and the two first gears 8 pass through the opening 27, and the fixing plate 5 is rotated so that the laser beam emitted by the alignment sensor passes through one of the threaded holes, and then a plurality of bolts 6 are placed in the placement opening 46;

[0040] After the main body and the processing part are placed, due to the setting of the alignment sensor, when the threaded hole on the hollow plate 2 is not aligned with the threaded hole on the fixed plate 5, an electrical signal will be generated and transmitted to the controller, and the controller will control the third pneumatic rod 29 to contract, so that the adjustment block 30 drives the second rack 33 to move right, so that the third gear 32 drives the vertical rod 31 to rotate, so that the placement table 17 drives the processing part to rotate, so that the threaded hole on the hollow plate 2 is aligned with the threaded hole on the fixed plate 5. When the corresponding threaded holes are aligned, the controller will control the third pneumatic rod 29 to stop running;

[0041] When the positioning is completed, the staff first controls the first pneumatic rod 18 to retract, so that the placement table 17 drives the main part to move downward, so that the fixed plate 5 contacts the hollow plate 2. After the placement table 17 moves downward, the second gear 20 is driven to rotate through the first rack 19, so that the screw rod 49 rotates, so that the limit block 47 drives the card 48 to move backward, thereby limiting the first gear 8. The staff controls the first motor 24 to operate, and the operation of the first motor 24 drives the bidirectional threaded rod 15 to rotate, thereby driving the two moving blocks 16 to move relative to each other, so that the tightening assembly drives the multiple bolts 6 to move above the corresponding threaded holes;

[0042] When the two moving blocks 16 move to the designated positions, the infrared sensor senses the distance between the two moving blocks 16 and generates an electrical signal to transmit to the controller, and the controller controls the first motor 24 to stop running, and controls the two second motors 40 and the electromagnet 35 to be powered on;

[0043] When the electromagnet 35 is energized, a repulsive force is generated on the slider 37, so that the slider 37 drives the mounting plate 39 and the arc block 45 to move downward, so that the multiple bolts 6 are vertically located above the corresponding threaded holes. When the arc block 45 moves downward, the arc block 45 is first moved to the top of the fixed plate 5. As the mounting plate 39 continues to move downward, the second spring 44 is compressed. Since the operation of the second motor 40 drives the multiple hexagonal wrenches 42 to rotate, when the bolts 6 are aligned with the hexagonal wrenches 42, the bolts 6 enter the hexagonal wrenches 42, and then through the rotation of the second motor 40 and the repulsive force of the electromagnet 35, the multiple bolts 6 are rotated into the corresponding threaded holes, thereby fixing the main body and the processing part together;

[0044] When the fixation is completed, the staff controls the second motor 40 to stop running, and first controls the electromagnet 35 to cut off the power, so that the two sliders 37 drive the mounting plate 39 to move back and reset. At this time, due to the obstruction of the bolt 6, the two arc blocks 45 cannot move. Then the staff controls the first motor 24 to drive the bidirectional threaded rod 15 to rotate in the opposite direction, so that the two moving blocks 16 drive the tightening components to move away from each other, so that the arc block 45 is separated from the bolt 6. After separation, under the elastic action of the second spring 44, the arc block 45 will be reset. At this time, the staff can control the two first pneumatic rods 18 to stretch, so that the placement table 17 and the fixed processing roller move up, separate the processing roller from the rotating table 21, and then lift the fixing frame 4 from the placement slot 26 and then pull it out from the opening 27.

[0045] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
