Description

Technical Field

[0001] The invention relates to the technical field of gear processing and welding, in particular to a high-efficiency welding device for gear processing. Background Art

[0002] Gears are mechanical parts with teeth that can mesh with each other. They are widely used in mechanical transmission and the entire mechanical field. Gears transmit power from one shaft to another through meshing teeth, realizing the transmission and conversion of motion and power. During the meshing process, the teeth of the driving wheel push the teeth of the driven wheel, causing the driven wheel to rotate, thereby completing the power transmission. Cylindrical gears: The tooth surface is a cylindrical surface, which is divided into spur gears, helical gears and herringbone gears. Spur gears have poor transmission stability, but are simple to manufacture and install; helical gears have a large overlap, stable transmission, and high load-bearing capacity; herringbone gears can offset axial forces and are often used in high-power transmission.

[0003] In the process of gear processing, in order to repair some gear sets damaged by production defects and internal stress and those damaged during durability testing, subsequent repairs will be carried out during production for subsequent inspection and life testing. In addition, welding technology is used to connect multiple parts into a complete gear, which is convenient for processing and manufacturing, and can also save materials and costs. In this process, a welding device is used to weld the structure to cooperate with production. However, the existing welding device lacks a mechanism for fixed welding of different gears and gear sets during the welding process due to the different sizes of the welded gears. In addition, when welding, arc welding, submerged arc welding or electroslag welding will produce molten liquid at the welding position. The welding slag in the molten metal floats due to buoyancy and surface tension. If the operation is improper, the welding slag is easy to be deposited in the molten metal, thereby affecting the stress in the welding and causing internal damage. During welding, some welding slag and smoke splashes will affect the quality of welding and affect the penetration of operators, thereby causing a certain reduction in welding quality. Based on this, an efficient welding device for gear processing is proposed. Summary of the invention

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the device is in use, the user places the welding gear to be welded on the top of the receiving and placing table, and before that, a notch is opened at the repaired position, and then the mounting mechanism is rotated to slide under the sliding support of the arc sliding block, and is placed on the opposite side of the mounting mechanism through the clamping assembly, and is inserted into the inner side of the mounting hole through the fixing bolt, and the fixing bolt is tightened to fix the ball column base on the opposite side of the mounting plate, and then according to the size of the placed welding gear, the mounting mechanism is rotated and the length of the clamping assembly is compressed, the telescopic outer cylinder is compressed inside the telescopic inner rod and the angle position is adjusted under the rotation support of the ball socket seat body and the ball column base, and the telescopic outer cylinder compresses and squeezes the reset spring inside the telescopic inner rod to maintain the relative position of the telescopic outer cylinder and the telescopic inner rod.

[0020] 2. When the rotating motor starts to rotate, it drives the output shaft and the moving gear to rotate.

[0021] 3. When welding operation that generates welding slag is performed, the vibration power motor is started to rotate to drive the eccentric wheel to rotate, and the eccentric wheel and the rolling bearing roller are in rolling contact. The eccentric rotation of the eccentric wheel causes the rolling bearing roller to move up and down, and the up and down movement is transmitted to the movable column through the limit frame, and the sealing piston 2 is driven to move through the movable column. The movement of the sealing piston 2 exerts a position effect on the gas inside the connecting tube.

Through the elastic limit of the supporting spring, the micro-vibration effect is transmitted to the inner side of the top support, and the metal solution generated during the welding process destroys the liquid tension, reduces the effect of deposition inside the welding molten liquid, changes the flow state of the welding liquid, affects the surface tension of the welding liquid, and thereby enhances the buoyancy effect, causes the welding slag to float out, ensures the operation quality during the welding process, avoids internal cracks caused by welding slag deposition, and thus ensures the operation effect.

The meshing action of the moving gear part 604 and the meshing rack 501 presents an active movement effect, which is convenient for driving the arc-shaped concave plate seat 601 to slide on the inner side of the sliding frame 5, and the rolling ball position of the micro universal ball wheel 607 contacts the inner wall of the limiting ring groove 502 to provide rolling support, and the bearing roller sleeve 608 rolls on the inner side of the limiting ring groove 502, which increases the lateral stability of the structure and facilitates maintaining the limiting position, thereby facilitating the movement of the structure and increasing the active rotation effect. The overall circumferential position rotation adjustment is convenient for cooperating with the dead angle movement of the welding operation, thereby increasing the convenience of angle adjustment, providing a relatively stable structural component for the welding control equipment, facilitating efficient operation and adjustment positions including multiple ranges and angles, and improving operating efficiency.

[0049] In another embodiment, Figure 1-Figure 10 As shown, the ball screw moving mechanism 7 includes a screw rod 701, a servo motor 702 and a slide rod 703. One end of the screw rod 701 is drivingly connected to the output end of the servo motor 702, and the end of the screw rod 701 away from the servo motor 702 is fixed to the opposite side of the mounting frame plate 602 through a bearing support, and the end of the servo motor 702 away from the screw rod 701 is fixed to the opposite side of the mounting frame plate 602. Both ends of the slide rod 703 are fixedly mounted on the opposite sides of the mounting frame plate 602. The interior of the ball screw moving seat 8 is threadedly sleeved with the outer side of the screw rod 701, and the interior of the end of the ball screw moving seat 8 away from the screw rod 701 is slidably sleeved with the slide rod 703.

[0050] The rotation of the servo motor 702 drives the screw rod 701 to rotate, and the screw rod 701 is connected to the ball screw moving seat 8 by threaded transmission. The ball screw moving seat 8 maintains a relatively stable position with the support of the slide rod 703, which enables the ball screw moving seat 8 to exhibit linear movement. In conjunction with the rotational movement of the power moving mechanism 6, the relative stability of the structure is increased, thereby maintaining the stability of the structure, facilitating the coordination of multi-angle coverage effects, and indirectly improving the efficiency of the operation.

[0051] In another embodiment, Figure 1-Figure 4 and Fig.13 As shown, the welding head clamping mechanism 9 includes a mounting tube 901 and a welding head 902. The welding head 902 is placed inside the mounting tube 901. The side wall of the mounting tube 901 is threaded with four mounting bolts 903. The opposite ends of the four mounting bolts 903 are rotatably clamped on the outside of the welding head 902. The four mounting bolts 903 are evenly distributed in a circle inside the welding head 902. A welding slot 1901 is provided on the top of the welding gear 19. The specifications and dimensions of the welding slot 1901 are compatible with the specifications and dimensions of the output end of the welding head 902. The welding gear 19 is placed on the top of the receiving and placing table 10.

[0052] As the electric-controlled telescopic rod 801 moves downward, and the power moving mechanism 6 and the ball screw moving mechanism 7 adjust their positions, the welding position of the welding head 902 is kept relative to the welding slot 1901. During welding, the welding head 902 is moved along the position of the welding slot 1901 for welding, thereby maintaining a relatively stable structural effect and facilitating mobile welding. The setting of the mounting bolts 903 makes it convenient to remove the welding head 902 and replace weldings of different specifications, thereby facilitating the adjustment of the welding mechanism operation.

[0053] In another embodiment, Figure 1-Figure 12As shown, the four elastic support mechanisms 11 all include an outer sleeve 1101, the inner side of the outer sleeve 1101 is movably sleeved with a sealing piston 1105, the top of the sealing piston 1105 is fixedly installed with an inner sleeve column 1102, the outer side of the inner sleeve column 1102 is movably sleeved with a limiting ring 1103, the outer side of the limiting ring 1103 is fixedly sleeved on the inner wall of the top of the outer sleeve 1101, the outer side of the outer sleeve 1101 is sleeved with a support spring 1104, and both ends of the support spring 1104 are connected through the mounting seat They are fixedly connected to the outer sleeve 1101 and the inner sleeve column 1102 respectively. The two ends of the four elastic support mechanisms 11 are fixed to the opposite sides of the top support 1 and the bottom support 13 through the mounting seats. The bottom surface of the bottom support 13 is fixedly mounted with four leg mounting members 12. The air pressure connecting mechanism 15 includes a connecting ball shell 1502. The four sides of the connecting ball shell 1502 are connected with connecting pipes 1501. The opposite ends of the connecting pipes 1501 are fixedly passed through the leg mounting members 12 and are connected to the inside of the outer sleeve 1101. The bottom of the ball shell 1502 is connected with a connecting tube 1508, and the inner side of the connecting tube 1508 is movably sleeved with a sealing piston 1507, and the bottom of the sealing piston 1507 is fixedly installed with a movable column 1506, and the bottom end of the movable column 1506 is fixedly installed with a limit frame 1504, and the inner side of the limit frame 1504 is rollingly installed with a rolling bearing roller 1505, and the top of the limit frame 1504 is fixedly installed with a limit spring 1503, and the top of the limit spring 1503 is fixedly installed with an outer support plate 1509. The outer support plate 1509 is fixedly sleeved on the outer side of the connecting tube 1508, and a mounting bracket 1701 is fixedly installed on the outer side of the vibration power motor 17. The mounting bracket 1701 is fixedly installed on the bottom of the bottom support 13. The output end of the vibration power motor 17 is transmission-connected with an eccentric wheel 1702, and the outer side of the eccentric wheel 1702 is in rolling contact with the outer side of the rolling bearing roller 1505. Compressed gas is arranged inside the connecting tube 1501, the connecting ball shell 1502, the connecting tube 1508 and the outer sleeve 1101.

[0054] When welding operation that produces welding slag is carried out, the vibration power motor 17 is started, and the rotation of the vibration power motor 17 drives the eccentric wheel 1702 to rotate. The eccentric wheel 1702 rolls in contact with the rolling bearing roller 1505, and the eccentric rotation of the eccentric wheel 1702 causes the rolling bearing roller 1505 to move up and down, and the up and down movement is transmitted to the movable column 1506 through the limit frame 1504, and the sealing piston 1507 is driven to move through the movable column 1506. The movement of the sealing piston 1507 exerts a position effect on the gas inside the connecting tube 1508. With the high-frequency movement, the compressed gas is transmitted to the inside of the outer sleeve 1101 through the connecting tube 1501. Although the high-pressure gas is in a compressed state, it still has a certain compressibility and elasticity. When the sealing piston 1507 vibrates, it will produce periodic squeezing and release on the gas in contact with it. When the gas is squeezed, the distance between molecules decreases and the pressure increases; when the gas is released, the distance between molecules increases and the pressure decreases. This periodic change of pressure will propagate in the gas in the form of waves, thereby transmitting the vibration from the sealing piston 1507 to the sealing piston 1105 via the connecting pipe 1501, thereby realizing vibration transmission, and driving the inner sleeve 1102 to vibrate through the sealing piston 1105, and through the elastic limit of the supporting spring 1104, the micro-vibration effect is transmitted to the inner side of the top support 1, and the metal solution is generated during the welding process, thereby destroying the liquid tension, reducing the effect of deposition inside the welding molten liquid, changing the flow state of the welding liquid, affecting the surface tension of the welding liquid, and thereby enhancing the buoyancy effect, causing the welding slag to float out, ensuring the operation quality during the welding process, avoiding internal cracks caused by welding slag deposition, and thus ensuring the operation effect.

[0055] In another embodiment, Figure 1-Figure 10 As shown, the receiving and placing table 10 includes a hollow placing plate 1001, a supporting sleeve 1002 is fixedly installed on the bottom of the hollow placing plate 1001, a threaded bar 1003 is arranged on the inner side of the supporting sleeve 1002, a fixing ring 1004 is threadedly connected to the inner side of the supporting sleeve 1002 through the threaded bar 1003, a stainless steel screen 1005 is fixedly installed on the inner side of the fixing ring 1004, and a filter paper disc 1006 is placed on the top of the stainless steel screen 1005.

[0056] When the welding gear 19 is placed on the top of the receiving and placing table 10, the welding operation fan assembly 16 starts to rotate, and a negative air pressure is formed at the bottom of the top support 1 through the rubber soft sleeve 14. The airflow is transmitted downward through the air vent 1301 and forms an airflow flow on the inner side of the receiving and placing table 10. The airflow drives the welding smoke downward and is filtered through the filter paper disc 1006, thereby orienting the welding smoke to avoid affecting the visual system and image processing equipment as well as the observation of the operator. The hollow placement plate 1001 receives the welding slag, so that it is convenient to remove the receiving and placing table 10 for cleaning, and the filter paper disc 1006 is replaced by rotating the fixing ring 1004 to remove it from the inner side of the threaded strip 1003 and the support sleeve 1002, thereby facilitating stable operation, thereby increasing the protection effect, facilitating auxiliary operation, and increasing the relative stability of the overall structure.

[0057] In another embodiment, Figure 1-Figure 10 As shown, the bottom end of the rubber soft sleeve 14 is fixedly mounted on the top of the bottom support 13, and the rubber soft sleeve 14 is located on the outside of the air vent 1301 and the fan assembly 16. The top surface of the top support 1 is provided with a slot for placing the receiving and placing platform 10, which is connected and has a sunken support groove structure. The size of the rubber soft sleeve 14 is larger than that of the receiving and placing platform 10.

[0058] The flexible operation of the rubber soft sleeve 14 makes it easy to operate under the guidance of airflow without affecting the vibration of the top support 1, thereby ensuring stability and facilitating use. A sunken installation groove is provided on the top of the top support 1 to facilitate the placement of the receiving platform 10, and the bottom of the sunken installation groove is connected to facilitate the passage of airflow and stable air guidance, thereby facilitating the use of the structure.
