Description

Technical Field

[0001] The present invention relates to the technical field of gear box production, in particular to gear box laser welding production equipment. Background Art

[0002] At present, in order to improve the compressive strength of the gearbox, it is necessary to use laser welding technology to reinforce the box body to improve the wear resistance and corrosion resistance of the gearbox. Different from the reinforcement of the outer surface of the gearbox, the reinforcement process of the inner wall of the box requires the use of laser cladding to clad its surface with an alloy layer. However, the existing laser cladding operation still has certain defects during actual use. Since the inner wall of the gearbox is exposed to the environment, as the laser cladding operation continues, due to the change in temperature in the processing area, the moisture in the environment will cause irregular pores in the cladding of the inner wall of the gearbox. As the gearbox heats up and cools down, more serious cracks will appear on the box wall after cladding.

[0003] In view of this, a gearbox laser welding production equipment was designed to solve the above problems. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in the present invention is: Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0006] In a preferred embodiment, the present invention can be further configured as follows: the cavity blocking mechanism further includes a backing plate fixedly mounted on the outside of the reinforced inner gasket, the outer wall of the sealing gasket is provided with a slot, and the backing plate is adapted to be snapped into the slot, two bolts are inserted into the backing plate, and the threaded sections of the bolts are fixedly mounted in the sealing gasket; A flow guide tube is fixedly installed inside the backing plate and the reinforced inner pad, and the port at the inner end of the flow guide tube is flush with the inner wall of the reinforced inner pad and the sealing pad.

[0009] In a preferred example, the present invention can be further configured as follows: a chassis is fixedly mounted on the middle of the top surface of the base plate, a motor is fixedly mounted in the chassis, and a gear is mounted on the motor, and the teeth of the gear are adapted to engage with the auxiliary rotating member.

[0010] In a preferred example, the present invention can be further configured as follows: the outer support plate is in an L-shaped structure as a whole, and the inner end of the outer support plate is adapted to bear pressure on the outer wall of the sealing gasket.

[0011] In a preferred example, the present invention can be further configured as follows: a slit is provided at the bottom of the external ring sleeve, and the gearbox body is adapted to fit inside the slit, so as to effectively dissipate heat from the laser-clad gearbox body.

[0012] In a preferred example, the present invention can be further configured as follows: the drawer plate is in an arc-shaped structure, and the length of the drawer plate is twice the length of the external ring sleeve.

[0015] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. The present invention uses the gearbox body as the machining center and sets two sets of cavity blocking mechanisms symmetrically distributed at both ends of the gearbox body. The two sets of cavity blocking mechanisms are controlled by the clamping mechanism to adapt and clamp the two ends of the gearbox body, and the two sets of cavity blocking mechanisms are wrapped by the box wall cladding mechanism. Finally, the gearbox body will be in a closed environment until the laser welding end is inserted into the closed environment.

The two guide tubes are used to circulate the inert gas in the closed cavity. Finally, the inner wall of the gearbox body is laser clad, and the smoke and heat energy in the closed cavity can be taken away by the airflow, thereby improving the integrity of the gearbox vertebral body processing.

[0020] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0021] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0022] A gearbox laser welding production device provided by some embodiments of the present invention will be described below with reference to the accompanying drawings. Example 1:

[0023] Combine Figures 1 to 7 As shown, the present invention provides a gearbox laser welding production equipment, including a gearbox main body 400, two sets of cavity blocking mechanisms 200 for clamping the gearbox main body 400, a box clamping mechanism 100 installed on the two sets of cavity blocking mechanisms 200, and a box wall cladding mechanism 300 movably installed outside the two sets of cavity blocking mechanisms 200. The box clamping mechanism 100 is used to control the opening and closing of the two sets of cavity blocking mechanisms 200, and the two sets of cavity blocking mechanisms 200 are used to provide an effective clamping platform for the gearbox main body 400. The box wall cladding mechanism 300 is movably installed outside the two sets of cavity blocking mechanisms 200 and provides an auxiliary rotation platform for the laser welding end.

[0024] The clamping mechanism 100 includes a base plate 110, a fixed bracket 130 fixedly mounted on one end of the top of the base plate 110, and a sliding bracket 140 movably mounted on the other end of the top of the base plate 110. A slide groove is defined inside the base plate 110, and the sliding bracket 140 is movably mounted in the slide groove. Two sets of clamps 1101 are fixedly mounted on the bottom of the base plate 110, and a hydraulic component 120 is fixedly mounted in the two sets of clamps 1101 and is horizontally arranged. An end plate 1401 is fixedly mounted on the bottom of the sliding bracket 140, and the hydraulic sub-rod in the hydraulic component 120 is fixedly mounted inside the end plate 1401. A chassis 150 is fixedly mounted in the middle of the top surface of the bottom plate 110, along with a motor 1501 fixedly mounted in the chassis 150 and a gear 1502 mounted on the motor 1501. The teeth of the gear 1502 are adapted to mesh with the rotation-assisting component 320. The cavity blocking mechanism 200 includes two outer support plates 210, a reinforced inner pad 2101 fixedly mounted on the inner ends of the two outer support plates 210, and a sealing pad 230 mounted on the outside of the reinforced inner pad 2101; Two top pressure plates 2301 are fixedly installed in the middle of the inner side of the sealing gasket 230, and a bottom support plate 2302 is fixedly installed at the bottom of the inner side of the sealing gasket 230; The box wall cladding mechanism 300 includes an external ring 310 movably mounted outside the two sets of cavity blocking mechanisms 200, a slide groove 3101 is defined inside the external ring 310, a drawer plate 330 movably mounted in the slide groove 3101, and a slide seat 340 mounted in the middle of the drawer plate 330 and extending through the slide groove 3101. The middle portions of the fixed bracket 130 and the sliding bracket 140 are both U-shaped, which are used to provide an effective rollover path for the laterally extended drawer board 330; The gearbox body 400 is located at the bottom of the inner cavity of the external ring sleeve 310 and is adapted to be clamped by two sets of cavity blocking mechanisms 200 .

[0025] The hydraulic component 120 is preliminarily operated until the hydraulic sub-rod inside it extends outward. The outer end of the hydraulic sub-rod pushes the end plate 1401 and the sliding bracket 140 to move outward laterally. The cavity blocking mechanism 200 installed on the top of the sliding bracket 140 expands the gap with the other cavity blocking mechanism 200 to the maximum extent. The gearbox body 400 to be processed is then placed between the two cavity blocking mechanisms 200. The hydraulic sub-rod is then controlled to retract. As the hydraulic sub-rod retracts, the two cavity blocking mechanisms 200 can finally adapt and clamp the two ends of the gearbox body 400. After the gearbox body 400 is clamped and fixed, the box wall cladding assisting mechanism 300 is adapted to be installed outside the two sets of cavity blocking mechanisms 200. As the motor 1501 runs, the gear 1502 assists the rotation assisting member 320 to flip. After the regular flipping, the outer ring 310 and the drawer plate 330 carry the laser welding end to perform orderly tilting and side flipping. Finally, the inner wall of the gearbox body 400 can be effectively laser clad. The inert gas introduced into the closed cavity through the two flow guide tubes 220 can provide anti-pore protection for the laser cladding of the inner wall of the gearbox body 400, thereby avoiding problems such as cracks during the cladding of the inner wall of the gearbox body 400. Example 2:

[0026] Combine Figure 1 and Figure 7 As shown, based on the first embodiment, the cavity blocking mechanism 200 further includes a backing plate 2102 fixedly mounted on the outside of the reinforced inner pad 2101. A notch is formed on the outer wall of the sealing gasket 230, and the backing plate 2102 is adapted to be snapped into the notch. Two bolts 2103 are inserted into the backing plate 2102, and the threaded sections of the bolts 2103 are fixedly mounted in the sealing gasket 230. The guide tube 220 is fixedly installed inside the backing plate 2102 and the reinforced inner pad 2101, and the port at the inner end of the guide tube 220 is flush with the inner wall of the reinforced inner pad 2101 and the sealing pad 230; The outer support plate 210 is in an L-shaped structure as a whole, and the inner end of the outer support plate 210 is adapted to bear pressure on the outer wall of the sealing gasket 230 .

[0027] Preferably, the two top pressure plates 2301 and the bottom support plate 2302 form a triangular frame, and the end of the gear box body 400 is inserted into the triangular frame until the two ends of the gear box body 400 are plugged into the two sets of triangular frames. The upward port of the gear box body 400 will face the closed inner cavity, and the inert gas will diffuse in the inner wall of the gear box body 400. As the laser cladding operation continues, the inert gas can effectively prevent the moisture in the environment from interfering with the inner wall of the gear box body 400. At the same time, the circulating inert gas can effectively dissipate heat from the inner wall of the gear box body 400. Example 3:

[0028] Combine Figure 5 and Figure 6 As shown, in the above embodiment, the box wall cladding assist mechanism 300 further includes two rotation assist members 320 fixedly mounted at both ends of the external ring 310, two locking bolts 3401 threadedly mounted in the slide 340, a pressure boosting gasket 3402 movably mounted on the inner ends of the locking bolts 3401, and a laser head sheath 350 inserted into the interior of the slide 340; A gap is formed at the bottom of the external ring 310, and the gearbox body 400 fits inside the gap to effectively dissipate heat from the laser-clad gearbox body 400. The drawer plate 330 is in an arc-shaped structure, and the length of the drawer plate 330 is twice the length of the external ring sleeve 310; An anti-skid pad is fixedly installed on the inner wall of the boosting gasket 3402, and the laser head sheath 350 is adapted to the inner cavity of the slide seat 340 for stabilizing and clamping the laser welding end.

[0029] In the initial state, the slide 340 and the laser head sleeve 350 are located in the middle of the top of the external ring sleeve 310. When in use, the drawer plate 330 is stretched horizontally until the slide 340 moves to one end of the external ring sleeve 310. At this time, the laser welding machine is operated until the laser is orderly flipped along the inner wall of the gear box body 400. As the drawer plate 330 slides at a uniform speed, the height of the laser welding end is adjusted inside the laser head sleeve 350. Finally, the laser welding end with the changed height can be used to perform adaptive cladding processing on the gradually changing hole depth of the gear box body 400.

[0030] The working principle and use process of the present invention are as follows: the two sets of cavity blocking mechanisms 200 are respectively fixedly installed on the top of the fixed bracket 130 and the sliding bracket 140, and the box wall cladding mechanism 300 is movably installed between the two sets of cavity blocking mechanisms 200. At the same time, the gear box body 400 to be processed needs to be inserted into the box wall cladding mechanism 300. As the hydraulic component 120 operates, the hydraulic sub-rod inside it contracts, which drives the end plate 1401 and the sliding bracket 140 to move closer to the fixed bracket 130, until the exposed ends of the gear box body 400 are adapted and clamped by the two sets of cavity blocking mechanisms 200, and the ports of the clamped gear box body 400 face upwards. Next, the laser welding tip is inserted along the laser head sheath 350. When the laser welding tip extends into the inner cavity of the box wall cladding mechanism 300 and reaches the designated area, the two locking bolts 3401 are adjusted with a wrench. The two pressurizing washers 3402 pushed by the two locking bolts 3401 tighten the laser head sheath 350 and the laser welding tip. Then, the two flow guide tubes 220 are used to transfer the inert shielding gas into the sealed cavity formed by the box wall cladding mechanism 300 and the two sets of cavity blocking mechanisms 200. As the laser welder operates, the laser irradiation directly illuminates the inner wall of the gearbox body 400. At this time, by running the motor 1501, the gear 1502 mounted on the motor 1501 assists in rotating one of the auxiliary rotating parts 320. The auxiliary rotating part 320 and the external ring 310 as a whole regularly reciprocate along the outside of the two sealing gaskets 230, and the laser welding end can effectively perform a cladding operation along the inner wall of the gearbox body 400. Under the protection of the inert gas, the problem of irregular air holes will not appear during the cladding of the inner wall of the gearbox body 400. After the laser welding end head flips regularly along the inner wall of the gear box body 400, the slide 340 is driven to move horizontally by controlling the drawer plate 330, and the laser welding end head clamped by the laser head sleeve 350 can perform horizontal cladding treatment on the remaining parts of the inner wall of the gear box body 400. During the horizontal movement of the drawer plate 330, according to the processing requirements of the gradual hole depth of the inner wall of the gear box body 400, the laser welding end head after horizontal movement can be height-controlled along the inside of the laser head sleeve 350. At this time, the laser welding end head can effectively perform cladding operation on the gradual hole depth in the gear box body 400.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
