Description

Technical Field

[0001] The field involved in this application, in particular, relates to a two-in-one multi-station rotor automatic aluminum casting production line. Background Art

[0002] The rotor is one of the important components of the motor, and the cast aluminum rotor is the most common structural form of the rotor. In related technologies, the cast aluminum rotor is generally prepared by pressure casting. Its essence is to stack a number of rotor punchings with grooves, and then fill the grooves with molten aluminum at a higher speed under pressure, and then form and solidify them under pressure to obtain a casting.

[0003] When casting aluminum, a turntable is usually set on a workbench, and there are several (usually four) workstations on the turntable. There are molds and oil cylinders directly above the workstations, and there are oil cylinders below the workstations. The mold is installed with a superimposed rotor. After the feeder feeds the material (aluminum liquid) to the workstation, the oil cylinder drives the rotor to move down to the workstation to close the mold. The oil cylinder below the workstation quickly pushes the poured aluminum liquid into the rotor to quickly form the aluminum liquid. Aluminum casting production lines are usually equipped with cooling devices to cool the aluminum liquid. Therefore, an aluminum casting device occupies a large area. Due to the limitation of the plant area, the number of aluminum casting devices in the plant is limited, and its production efficiency often does not meet the demand, which needs to be improved. Utility Model Content

[0004] In order to improve the production efficiency of the aluminum casting production line, the present application provides a two-in-one multi-station rotor automatic aluminum casting production line.

[0005] The present application provides a two-in-one multi-station rotor automatic aluminum casting production line, which adopts the following technical solution:

[0006] A two-in-one multi-station rotor automatic aluminum casting production line comprises a workbench, a first work area arranged on the workbench, a second work area arranged on the workbench, an aluminum furnace, a first soup feeder and a second soup feeder, wherein the first work area and the second work area both comprise a driving assembly, a turntable, a plurality of mold racks arranged on the turntable, a mold clamping assembly and a feeding assembly, wherein the driving assembly is used to drive the turntable to rotate, and the plurality of mold racks are circumferentially arranged at equal intervals along the rotation axis of the turntable, the mold clamping assembly comprises a first oil cylinder and a mounting mold, wherein the mounting mold is used to install a rotor, and the first oil cylinder is used to drive the mounting mold into the mold rack; the first soup feeder is used to scoop the aluminum alloy melt in the aluminum furnace into the mold rack in the first work area, and the second soup feeder is used to scoop the aluminum alloy melt in the aluminum furnace into the mold rack in the second work area.

[0007] By adopting the above technical solution, two work areas with the same configuration are set up, and several mold racks (at least two) are installed on the turntable of each work area. The first soup feeder and the second soup feeder take materials in the aluminum furnace at the same time and inject materials into the mold racks on the first work area and the second work area respectively. The rotor is installed on the mounting mold and moves downward through the first oil cylinder to complete the mold closing. Finally, the aluminum alloy melt is injected into the rotor through the feeding assembly to complete the aluminum casting. Compared with the traditional method of setting up one work area on one workbench to cast aluminum for the rotor, the two-in-one multi-station rotor automatic aluminum casting production line places two work areas on one workbench and is equipped with two soup feeders and an aluminum furnace, thereby saving costs to a certain extent. The area occupied by the workbench after the merger is also reduced, so that more work areas can be set up to improve the efficiency of aluminum casting (the number of workbenches remains unchanged, and the number of work areas increases).

[0008] Optionally, there are four mold racks in the first working area and the second working area, and each of the mold racks is provided with a fixing component, and the fixing component fixes the mold rack on the turntable.

[0009] By adopting the above technical solution, four mold racks are set up and installed on a turntable, and the four workstations can continuously complete the aluminum casting operation and maintain the aluminum casting efficiency.

[0010] Optionally, the fixing assembly includes four positioning assemblies and four fixing screws, and the positioning assemblies and the fixing screws are arranged in a one-to-one correspondence. The positioning assembly includes bearings, guide columns and pressure plates. The mold frame is provided with guide holes for bearing installation. The guide columns pass through the bearings and penetrate the turntable. The pressure plate is arranged at the bottom of the turntable and is fixed to the guide columns; the fixing screws fix the mold frame to the turntable.

[0011] By adopting the above technical solution, a positioning assembly is set to position the mold frame. After the positioning is completed, the mold frame is fixed to the turntable by a fixing screw. The four sets of positioning assemblies and the fixing screws enable the mold frame to be stably fixed on the turntable.

[0012] Optionally, a mounting hole is provided on the turntable, and the mounting hole is used to accommodate the mold frame.

[0013] By adopting the above technical solution, a mounting hole is provided for mounting the mold frame, so that the mold frame can be easily mounted on the turntable.

[0014] Optionally, two aluminum cylinders are provided on the workbench, and the two aluminum cylinders are respectively arranged in the first working area and the second working area. The top surface of the aluminum cylinder is flush with the bottom surface of the mold frame. A feeding channel is opened on the top surface of the aluminum cylinder, and the feeding channel is for accommodating the rotor. The mounting mold is located directly above the feeding channel. When the first oil cylinder drives the mounting mold to move, the rotor is driven to extend into the feeding channel, and the feeding assembly pushes the molten aluminum alloy upward into the rotor.

[0015] By adopting the above technical solution, the first soup feeder and the second soup feeder simultaneously feed the molten aluminum alloy into the mold racks on the first working area and the second working area, and the molten aluminum alloy is injected into the feeding channel. Then the corresponding first oil cylinder drives the rotor into the molds on the first working area and the second working area and completes the mold closing. At this time, the rotor enters the feeding channel to wait for the feeding assembly to cast aluminum.

[0016] Optionally, the feeding assembly includes a lower cylinder fixing rod arranged on the workbench, a lower cylinder fixing plate arranged at the bottom end of the lower cylinder fixing rod and a second oil cylinder arranged on the lower cylinder fixing plate, and the piston rod of the second oil cylinder extends into the feeding channel.

[0017] By adopting the above technical solution, a second oil cylinder is set up and the aluminum alloy melt is pushed upward by the piston rod of the second oil cylinder, so that the aluminum alloy melt is injected into the groove on the rotor, and then the aluminum alloy melt is quickly cooled to complete the aluminum casting.

[0018] Optionally, the driving assembly includes a servo motor and a reducer, the output shaft of the servo motor is fixed to the input shaft of the reducer, a cam is coaxially fixed to the output shaft of the reducer, and the turntable is fixed to the cam.

[0019] By adopting the above technical solution, the servo motor can control the rotation speed and is connected to the turntable through the reducer, thereby driving the turntable to rotate regularly to automatically unload the rotor after cast aluminum.

[0020] Optionally, a conveyor belt is provided on the workbench, and the turntable rotates 90° to convey the aluminum-cast rotor to the conveyor belt. A clamp is provided on the workbench, and the clamp is used to clamp the aluminum-cast rotor and place it on the conveyor belt.

[0021] By adopting the above technical solution, the rotor is driven by the turntable to rotate 90° after being cast with aluminum, and the next station continues to cast aluminum on the new rotor. Then the second rotor is rotated 90°, and then the third rotor is cast with aluminum at the third station. At this time, the first aluminum-cast rotor is clamped by the clamp to the conveyor belt and transferred to the collection area, and so on. The turntable drives the aluminum-cast rotor to move to the conveyor belt, and is clamped by the clamp to be placed on the conveyor belt.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By setting two work areas with the same configuration, a number of mold racks (at least two) are installed on the turntable of each work area, the first soup feeder and the second soup feeder take materials from the aluminum furnace at the same time and inject materials into the mold racks on the first work area and the second work area respectively, the rotor is installed on the installation mold and moves downward through the first oil cylinder to complete the mold closing, and finally the aluminum alloy melt is injected into the rotor through the feeding assembly to complete the aluminum casting. Compared with the traditional setting of one workbench and one work area to cast aluminum for the rotor, the two-in-one multi-station rotor automatic aluminum casting production line places two work areas on one workbench and is equipped with two soup feeders and an aluminum furnace, thereby saving costs to a certain extent. The area occupied by the combined workbench is also reduced, so that more work areas can be set to improve the efficiency of aluminum casting (the number of workbenches remains unchanged, and the number of work areas increases);

By analogy, the turntable drives the cast rotor to move to the conveyor belt and is clamped by the clamp and placed on the conveyor belt. BRIEF DESCRIPTION OF THE DRAWINGS
