Description

TECHNICAL FIELD

[0001] The application relates to the technical field of shaft flow fan casing processing, in particular to an industrial shaft flow fan casing laser welding post-processing grinding machine. BACKGROUND

[0002] The shaft flow fan is widely used, that is, the airflow is in the same direction as the shaft of the fan blade, for example, the fan of an air conditioner outdoor unit is a shaft flow type operation fan. The reason why it is called "axial flow type" is that the gas flows parallel to the fan shaft. The axial flow fan is usually used in places where the flow requirement is high and the pressure requirement is low. The axial flow fan is fixed in position and moves air. The axial flow fan is mainly composed of a fan impeller and a casing, and has a simple structure but high data requirement. The casing of the axial flow fan is in a cylindrical shape, and a flange is made at both ends of the casing by spinning or welding to enhance the strength of the casing and can be used for installing protective covers at both ends. In addition, a support or mounting seat for mounting the casing is arranged outside the casing, and a mounting seat for mounting a motor and a fan blade is arranged inside the casing.

[0003] During the production of the shaft flow fan, the flange and other structures are welded at the corresponding positions of the cylinder after the steel plate is rolled and welded, so as to perform welding production. During the welding process, a clamp is usually used to fix and clamp the flange and the cylinder for welding. The position of clamping needs to be adjusted to assist welding. When different sizes of shaft flow fan casings are welded, the clamp usually needs to be replaced. During the laser welding of the shaft flow fan casing, very fine smoke is generated, which affects the working environment. The diameter of the smoke particles is usually 0.1-1 mu m, which is easy to suspend in the air. If it is not discharged in time, it may adhere to the surface of the workpiece or the laser lens. Some smoke components (such as Cr 6+ , manganese compounds) are toxic and can harm the respiratory tract if inhaled for a long time. During the welding process, the metal is rapidly vaporized due to high-energy laser, and the steam is sprayed at high speed, which will generate a recoil force on the molten pool. If the volume of the molten pool is small and the solidification is fast, in order to adapt to the larger power of the laser energy, the recoil force may "blow away" part of the liquid metal from the molten pool, forming spatter and slag which is difficult to clean after adhering to the inner wall of the cylinder. If the front surface is not treated before welding, it will affect the welding process and quality, thereby affecting the production quality and efficiency. Therefore, the industrial shaft flow fan casing laser welding post-processing grinding machine is proposed. SUMMARY

The mounting part of the electric control telescopic rod 303 is welded on the outer wall of the bearing wall of the support bearing frame 310, so the electric control telescopic rod 303 and the mounting plate 305 can rotate with the support bearing 304 and the support bearing frame 310 providing the circumferential position.

At this time, the electric control telescopic rod 303 pushes the alignment column 306, the electromagnet column 308 and the flange to the appropriate welding position. With the welding process, the flange and the cylinder form a fixed point, and the rolling mechanism 8 still applies a rotating force to the cylinder to adjust the welding position. At this time, the flange must rotate with the cylinder, so that the electromagnet column 308, the alignment column 306, the mounting plate 305 and the electric control telescopic rod 303 will produce synchronous rotation, so the support bearing 304 and the support bearing frame 310 need to rotate to stabilize the position, and the insertion of the fixing bolt 307 into the alignment hole 309 limits the insertion, which is convenient for the installation of the alignment column 306 and can replace the new alignment column 306 to replace the alignment column 306 of different lengths, so as to change the pushing position of the flange and assist the structure to work, increasing the overall convenience.

[0048] In another embodiment, as shown in Figures 1-9As shown, the sealing support cylinder 702 is a hollow structure, and the hydraulic telescopic column three 703 is circumferentially and linearly uniformly distributed on the outside of the sealing support cylinder 702. The inside of the hydraulic telescopic column three 703 is in communication with the inside of the sealing support cylinder 702. The input end of the sealing support cylinder 702 is in communication with the output end of the hydraulic driving mechanism 5 through a pipeline.

[0049] The hollow inside the sealing support cylinder 702 facilitates the input of hydraulic oil. When the hydraulic driving mechanism 5 inputs hydraulic oil into the inside of the sealing support cylinder 702 through the oil pipeline, the hydraulic oil is isostatically delivered to the inside of the hydraulic telescopic column three 703 through the chamber of the sealing support cylinder 702 at this time, and the synchronous jacking and expansion of the hydraulic telescopic column three 703 promotes the high-temperature-resistant rubber roller 704 to be on the inner wall of the cylinder, thereby promoting the cylinder to be on the outside of the sealing support cylinder 702, promoting the sealing support cylinder 702 to maintain the rotating position of the concentric shaft with the cylinder, and the sealing support cylinder 702 and the support cylinder one 302 are both kept in the synchronous position by the synchronous output of the power of the hydraulic power output device 11, so as to facilitate the coaxial structure to assist the welding operation, increase the relative stability of the structure, increase the stability of the structure, and facilitate synchronization.

[0050] In another embodiment, as shown, Figures 1-12 As shown, the adjusting holes 103 are linearly and uniformly distributed on the top of the workbench 1, and the adjusting holes 103 are linearly and symmetrically and uniformly distributed on both sides of the mounting groove 102. The servo motor 801 is embeddedly installed in the inside of the workbench 1 through the groove, and the end of the rotating shaft 802 away from the servo motor 801 is rotatably fixed to the inner wall of the mounting groove 102 through a bearing seat. One side of the strong electromagnet 804 is fixedly installed with the brush two 809, one end of the brush two 809 is in electrically sliding contact with the slip ring two 805, the slip ring two 805 is movably sleeved on the outside of the rotating shaft 802, one side of the slip ring two 805 is fixedly installed with the fixed supporting rod 806, the fixed supporting rod 806 is fixedly installed on the inner wall of the mounting groove 102, the other side of the strong electromagnet 804 is fixedly installed with the slip ring one 808, the outside of the slip ring one 808 is in electrically sliding contact with the fixed brush 807, the fixed brush 807 is fixedly installed on the inner wall of the mounting groove 102, and the strong electromagnet 804 is linearly and uniformly distributed on the outside of the rotating shaft 802.

[0051] The position of the adjusting hole 103 facilitates the adjustment of the position of the side cylinder limiting seat 104, which limits the two ends of the cylinder and the flange to avoid the cylinder from deviating during welding, and plays an auxiliary limiting safety role. The high-temperature-resistant rubber roller 704 is in the same axial direction as the rotating direction of the cylinder and the rolling mechanism 8, and the high-temperature-resistant rubber roller 704 limits the lateral movement of the cylinder, so that the combination of the side cylinder limiting seat 104 and the safety limiting function can facilitate the welding operation of the cylinder in a limited position. When the servo motor 801 rotates, it drives the rotating shaft 802 to rotate, and the strong electromagnet 804 generates an electromagnetic force that attracts the outer wall of the cylinder through the high-temperature-resistant rubber ring 803, exerting a rotating force on the cylinder. The power source of the strong electromagnet 804 is the power supply connected to the slip ring two 805, which is connected to the fixed support rod 806 through the fixed mounting groove 102, and the fixed brush two 809 is connected to the strong electromagnet 804, thereby realizing current conduction at one end. The current at the other end of the strong electromagnet 804 is conducted through the fixed slip ring one 808 along with the rotation of the strong electromagnet 804, and then through the fixed brush 807 connected to the outer side of the slip ring one 808 to form a current loop. The fixed brush 807 is fixed in the mounting groove 102, and the slip ring one 808 is fixed on the outer side of the strong electromagnet 804, so that the current loop can be formed during rotation to start the electromagnetic effect of the strong electromagnet 804. This operation can also be achieved by using a conventional permanent magnet, but the purpose of using the strong electromagnet 804 is to facilitate the perfect rotation of the cylinder of the shell within a certain weight range, thereby assisting the operation.

[0052] In another embodiment, as shown in Figures 1-5 The hydraulic active mechanism 5 includes an electrically controlled telescopic column 501 fixedly installed on the top of the workbench 1.

The end of the oil delivery pipeline one 503 away from the sealing cylinder 502 is communicated with the inside of a sealing branch cylinder 702. The inside of the sealing cylinder 502, the oil delivery pipeline one 503, the sealing branch cylinder 702, and a hydraulic telescopic column three 703 are all provided with hydraulic oil.

[0053] When the electric control telescopic column 501 applies hydraulic power to the sealing support cylinder 702, the electric control telescopic column 501 is started to drive the power sealing piston 504 to move inside the sealing cylinder 502, so as to push the hydraulic oil to flow to the inside of the sealing support cylinder 702 through the oil pipeline 503, and then the pressure of the sealing support cylinder 702 promotes the hydraulic telescopic column three 703 to rise to the inner wall of the shell cylinder, so that the telescopic expansion of one electric control telescopic column 501 realizes the synchronous telescopic expansion of the hydraulic telescopic column three 703, thereby assisting the operation, reducing the use of additional power, and increasing the effect of synchronous expansion.

[0055] When the air flow processing mechanism 9 starts to adsorb the air flow, the strong fan 906 starts to extract the air flow inside the axial flow installation pipe 904 and the guide pipe 903 with strong wind power, the air flow is introduced through the corrugated hose 901 and the gas collector 902, the air flow of the corrugated hose 901 is introduced through the branch cylinder one 302 and the hollow pipe 1308, and the hollow pipe 1308 is connected through the adjustable telescopic pipe 1301, the air flow enters the inside of the hollow column 1302 through the air inlet hole 1303, and then forms an air flow circuit in the hollow column 1302, the adjustable telescopic pipe 1301, the hollow pipe 1308, the branch cylinder one 302 and the corrugated hose 901, and the hollow pipe 1308 is installed inside the branch cylinder one 302 through a plurality of bearings, so that the generated debris and particles are sucked into the hollow column 1302 during the grinding process, and the overflow is reduced, and the air flow of the gas collector 902 is introduced through the installation groove 102, reducing the dispersion of smoke dust, and the air flow is introduced into the guide pipe 903 through the corrugated hose 901 and the gas collector 902, and then the air flow is adsorbed and filtered by the filter assembly 905, first filtering 10 μm particles through the polyester fiber mesh, then filtering 0.3 μm particulate matter through the HEPA grade glass fiber filter cotton, and finally absorbing through the activated carbon fiber felt, thereby reducing the overflow of particles and smoke dust and increasing the environmental protection effect of the equipment, and the retaining ring 907 is installed on one side of the guide pipe 903 through the flange and bolt of the axial flow installation pipe 904, and the axial flow installation pipe 904 is also of the axial flow fan type, after installation, the axial flow installation pipe 904 limits the filter assembly 905 on the inside of the guide pipe 903 through the retaining ring 907, and the guide pipe 903 is fixedly welded on the outside of the bottom bracket 101, and the axial flow installation pipe 904 is movable, in order to replace the filter assembly 905, the axial flow installation pipe 904 is disassembled through the bolt, and then the retaining ring 907 is released from the limiting of the filter assembly 905, so that the filter assembly 905 is replaced and maintained regularly, thereby increasing the overall convenience, and the flange structure of the output end of the axial flow installation pipe 904 can be externally connected to the exhaust pipe to exhaust the extracted air flow, reducing the impact on the working environment.
