[0002] Welding equipment refers to the equipment required to implement the welding process. Welding equipment includes welding machines, welding process equipment and welding auxiliary equipment. However, various welding equipment on the market still have various problems. For example, automatic welding equipment is difficult to achieve welding at any position.

[0003] A patent with publication number CN116618919A discloses a welding device for processing metal products, including an electric motor, an output end of the electric motor is fixedly connected to a positioning device, the positioning device includes a groove shell, the inner wall of the groove shell is rotatably connected to a transmission shaft, the outer surface of the transmission shaft is sleeved with a transmission chain, the inner wall of the transmission chain is sleeved with a sprocket gear shaft, the outer surface gear of the sprocket gear shaft is meshed with a sprocket plate, the end of the sprocket plate away from the sprocket gear shaft is fixedly connected to a threaded rod, the end of the threaded rod away from the sprocket plate is fixedly connected to a four-corner rotating block, the motor is turned on to drive the transmission shaft to rotate, and the sprocket gear shaft is driven to rotate through the transmission chain to achieve left and right translation inside the groove shell, thereby changing the position of metal processing welding, thereby achieving position adjustment. After the welding is completed, the four-corner rotating blocks are rotated to disengage the sprocket plate from the meshing limit with the sprocket gear shaft, thereby correcting the welding position again.

[0004] In the current existing technology, when the existing gear shaft is processed and welded, the gear shaft and the shaft need to be butt-jointed and then welded by a welder. The gear shaft and the shaft are cast separately, and the side that needs to be joined cannot be kept in the best condition. Moreover, manual grinding cannot maintain the horizontal angle between the fitting surface of the gear shaft and the shaft. The polished surface will have a certain inclination angle or the polished surface is not polished thoroughly enough, which will lead to bubbles in the weld when the gear shaft and the shaft are welded because the fitting surface is not thorough enough. When the gear shaft and the shaft are operated at high speed, the bubbles will cause the gear shaft to break due to the bubbles.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1-4 and Figures 6 and 7 As shown, a gear shaft processing and welding device according to an embodiment of the present invention includes a gear shaft limiting frame 13 and a gear shaft 16 movably sleeved on the inner wall surface of the gear shaft limiting frame 13, a gear shaft pushing frame 14 movably sleeved on the outer surface of the gear shaft 16, and a support frame 15 located in the middle position of the gear shaft limiting frame 13 and the gear shaft pushing frame 14. Two groups of motor three 153 are fixedly installed on the outer surface of the support frame 15, and the output end of the motor three 153 is fixedly connected to a swing arm movably overlapped on the outer surface of the support frame 15. Plate 154, a grinding disc 157 is provided at one end of the swing arm plate 154; a slider 2 151 is fixedly installed on the bottom surface of the support frame 15, and the outer surface of the slider 2 151 is movably sleeved on the outer surface of the processing overlap table 11, and a lap strip 152 is fixedly connected to the inner wall surface of the support frame 15, and a clamping plate 155 is fixedly connected to the other end of the swing arm plate 154, and a docking groove 156 is provided on the outer surface of the clamping plate 155, and the inner wall surface of the docking groove 156 is movably adjusted on the outer surface of the lap strip 152; A hydraulic rod 2 143 is fixedly installed on the top surface of the gear shaft pushing frame 14, a downward pressure slide 142 is fixedly connected to the output end of the hydraulic rod 2 143, an arc-shaped downward pressure plate 144 is fixedly connected to the bottom surface of the downward pressure slide 142, and an anti-slip arc pad 145 is provided on the inner wall of the gear shaft pushing frame 14 and at the bottom edge position.

[0023] The gear shaft and the shaft rod are respectively sleeved on the inner wall surfaces of the gear shaft limiting frame 13 and the gear shaft pushing frame 14, and the required fitting surfaces are fitted so that the fitting surfaces of the gear shaft and the shaft rod can be kept at the same horizontal angle. After alignment, the gear shaft and the shaft rod are moved apart. At this time, the swing arm plate 154 is rotated by the motor 3 153 so that the grinding disc 157 moves to the outer surface of the gear shaft and the shaft rod. Since the swing angles and directions of the two sets of grinding discs 157 are at the same horizontal angle at this time, when the grinding disc 157 is grinding on the surface of the gear shaft and the shaft rod, the fitting surfaces of the gear shaft and the shaft rod can be leveled under the grinding of the grinding disc 157. Before the gear shaft is clamped, the hydraulic rod 2 143 is cooperated to lower the downward pressure slide 142, and the arc-shaped downward pressure plate 144 is squeezed on the shaft surface of the gear shaft, and the gear part of the gear shaft is overlapped on the side edge position of the anti-slip arc pad 145 and the arc-shaped downward pressure plate 144. The arc-shaped downward pressure plate 144 and the anti-slip arc-shaped pad 145 are used to limit the side surface of the gear, and under the downward pressure of the arc-shaped downward pressure plate 144, the gear shaft is firmly positioned inside the gear shaft pushing frame 14 under the limitation of the anti-slip arc pad 145 and the arc-shaped downward pressure plate 144, reducing the shaking of the gear shaft during processing.

[0024] like Figures 1 to 2 and Figure 7 As shown, a limit bar 141 is fixedly connected to the inner wall surface of the gear shaft pushing frame 14, and the outer surface of the pressing slide 142 is movably overlapped on the outer surface of the limit bar 141. A motor 2 147 is fixedly installed on the top surface of the processing overlapping table 11, and a threaded rod 2 146 is fixedly connected to the output end of the motor 2 147. The outer surface of the threaded rod 2 146 is threaded and movably sleeved on the outer surface of the gear shaft pushing frame 14.

[0025] When hydraulic rod 2 143 presses down the pressing plate 142, the limit bar 141 cooperates to limit the movement of the pressing plate 142, so that the pressing plate 142 is in a vertical downward movement. The vertically downward pressing plate 142 will drive the arc-shaped pressing plate 144 to be squeezed and fitted on the top surface of the anti-slip arc pad 145 at a vertical angle, thereby vertically fitting the gear shaft. After the gear shaft is fixed, the threaded rod 2 146 is cooperated to push the gear shaft pushing frame 14, and the gear shaft is fitted with another shaft rod.

[0026] like Figures 1 to 4As shown, a limiting circular groove 131 is provided on the inner wall surface of the gear shaft limiting frame 13, and an electric roller 132 is provided on the inner wall surface of the limiting circular groove 131. A hydraulic rod 133 is fixedly installed on the side surface of the gear shaft limiting frame 13, and an arc-shaped pushing ring 134 is fixedly connected to the output end of the hydraulic rod 133. An arc-shaped groove 135 is provided on the inner wall surface of the arc-shaped pushing ring 134. A support arm 136 is fixedly connected to the side surface of the gear shaft limiting frame 13 and located at the edge position of one side of the limiting circular groove 131.

[0027] One end of the shaft rod is sleeved into the inside of the limiting circular groove 131, and at this time, the hydraulic rod 133 is cooperated to push the arc-shaped push ring 134, and then the arc-shaped groove 135 on the inner wall of the arc-shaped push ring 134 is used to squeeze the swing soft plate 137 on one end of the support arm 136, and the silicone elastic ring 138 on the inner wall of the swing soft plate 137 is fit and squeezed on the outer surface of the shaft rod. At this time, the extrusion of multiple silicone elastic rings 138 is used to increase the fitting force and friction force with the roller rod assembly, so that the roller rod is firmly positioned on the surface of the gear shaft limiting frame 13 under the limitation of the limiting circular groove 131 and the silicone elastic ring 138, reducing the situation where the roller rod will not shake too much and tilt during the later processing.

[0028] like Figures 1 to 5 As shown, a swinging soft plate 137 is fixedly connected to one end of the support arm 136, and the outer surface of the arc groove 135 is movably overlapped on the outer surface of the swinging soft plate 137. A silicone elastic ring 138 is fixedly connected to the inner wall of the swinging soft plate 137. The outer surface of the silicone elastic ring 138 is movably overlapped on the outer surface of the gear shaft 16. The bottom surface of the gear shaft limit frame 13 is fixedly connected to the processing overlap table 11, and a limiting slide groove 111 is provided on the top surface of the processing overlap table 11. A limiting sleeve 12 is fixedly installed on the two side surfaces of the processing overlap table 11. The limiting sleeve A motor 121 is fixedly installed on one side surface of 12, and a threaded rod 122 movably sleeved on the inner wall of the limiting sleeve 12 is fixedly connected to the output end of the motor 121. A slider 123 is threadedly movably sleeved on the outer surface of the threaded rod 122, and a hydraulic pump 124 is fixedly installed on the upper and lower inner wall surfaces of the slider 123. A fitting docking plate 125 is fixedly connected to the output end of the hydraulic pump 124, and a semicircular arc plate 126 is provided on one end of the fitting docking plate 125. A laser welder 127 is fixedly installed on the inner wall surface of the semicircular arc plate 126.

[0029] When the gear shaft and the shaft are polished, the motor 121 is used to rotate the threaded rod 122. Under the push of the threaded rod 122, the semicircular arc plate 126 is moved to the joint of the gear shaft and the shaft, and the hydraulic pump 124 is used to press down the fitting plate 125, so that the two sets of semicircular arc plates 126 are sleeved on the fitting outer surfaces of the gear shaft and the shaft. At this time, the laser welder 127 is used to weld and position the upper and lower joints of the gear shaft and the shaft to form welds. When the gear shaft and the shaft are fixed, the hydraulic rod 2 143 is used to retract the arc-shaped lower pressure plate 144, so that the gear shaft is in a loose state, and then the arc-shaped push ring 134 is pulled back by the hydraulic rod 133 to make the silicone elastic ring 138 detached from the surface of the shaft. At this time, the electric roller 132 is used to rotate the shaft, so that the laser welder 127 effectively welds the remaining positions of the gear shaft and the shaft surface.

[0030] Working principle: before the gear shaft is clamped, the hydraulic rod 143 is used to lower the pressing plate 142, and the arc-shaped pressing plate 144 is squeezed on the shaft surface of the gear shaft, and the gear part of the gear shaft is overlapped on the edge of one side of the anti-slip arc pad 145 and the arc-shaped pressing plate 144. The arc-shaped pressing plate 144 and the anti-slip arc pad 145 are used to define the side surface of the gear, and under the downward pressure of the arc-shaped pressing plate 144, the gear shaft is firmly positioned inside the gear shaft pushing frame 14 under the definition of the anti-slip arc pad 145 and the arc-shaped pressing plate 144, thereby reducing the shaking of the gear shaft during processing. When the hydraulic rod 143 presses down the pressing plate 142, the limiting bar 141 is used to limit the movement of the pressing plate 142 so that the pressing plate 142 moves vertically downward. The pressing plate 142 that moves vertically downward will drive the arc-shaped pressing plate 144 to press and fit on the top surface of the anti-slip arc pad 145 at a vertical angle, thereby fitting the gear shaft vertically. After the gear shaft is fixed, the threaded rod 146 is used to push the gear shaft pushing frame 14, so that the gear shaft is fitted with the other shaft rod. One end of the shaft is sleeved into the inner part of the limiting circular groove 131, and the hydraulic rod 133 is used to push the arc-shaped pushing ring 134, and then the arc groove 135 on the inner wall of the arc-shaped pushing ring 134 is used to squeeze the swing soft plate 137 on one end of the support arm 136, so that the silicone elastic ring 138 on the inner wall of the swing soft plate 137 is pressed against the outer surface of the shaft. At this time, the multiple silicone elastic rings 138 are used to increase the contact force and friction with the roller assembly, so that the roller is firmly positioned on the surface of the gear shaft limiting frame 13 under the limitation of the limiting circular groove 131 and the silicone elastic ring 138, thereby reducing the roller from shaking or tilting during the later processing. The gear shaft and the shaft rod are respectively sleeved on the inner wall surfaces of the gear shaft limiting frame 13 and the gear shaft pushing frame 14, and the required fitting surfaces are fitted so that the fitting surfaces of the gear shaft and the shaft rod can be kept at the same horizontal angle. After alignment, the gear shaft and the shaft rod are moved apart. At this time, the swing arm plate 154 is rotated by the motor 3 153 so that the grinding disc 157 moves to the outer surface of the gear shaft and the shaft rod. Since the swing angles and directions of the two sets of grinding discs 157 are at the same horizontal angle at this time, when the grinding disc 157 is grinding on the surface of the gear shaft and the shaft rod, the fitting surfaces of the gear shaft and the shaft rod can be leveled under the grinding of the grinding disc 157. When the gear shaft and the shaft are polished, the motor 121 is used to rotate the threaded rod 122. Under the push of the threaded rod 122, the semicircular arc plate 126 is moved to the joint of the gear shaft and the shaft, and the hydraulic pump 124 is used to press down the fitting plate 125, so that the two sets of semicircular arc plates 126 are sleeved on the fitting outer surfaces of the gear shaft and the shaft. At this time, the laser welder 127 is used to weld and position the upper and lower joints of the gear shaft and the shaft to form welds. When the gear shaft and the shaft are fixed, the hydraulic rod 2 143 is used to retract the arc-shaped lower pressure plate 144, so that the gear shaft is in a loose state, and then the arc-shaped push ring 134 is pulled back by the hydraulic rod 133 to make the silicone elastic ring 138 detached from the surface of the shaft. At this time, the electric roller 132 is used to rotate the shaft, so that the laser welder 127 effectively welds the remaining positions of the gear shaft and the shaft surface.
