Cooling manipulator of die-casting machine for automobile aluminum alloy hub

Abstract

The invention provides a cooling manipulator of a die-casting machine for an automobile aluminum alloy hub. The cooling manipulator comprises two supporting seats, a bracket, a transverse driving mechanism, a mechanical grabber, a longitudinal driving mechanism, a cooling water tank and a discharging rack, wherein the two supporting seats are arranged in parallel, and the bracket is mounted on the two parallel supporting seats; the transverse driving mechanism is mounted on the bracket; the mechanical grabber, comprising a moving rack, a first cylinder and a grabber body, is mounted on the transverse driving mechanism and is driven by the transverse driving mechanism to horizontally move; the longitudinal driving mechanism is mounted below the transverse driving mechanism; the cooling water tank is mounted in front of the longitudinal driving mechanism; the discharging rack is mounted at the front side of the cooling water tank. The cooling manipulator of the die-casting machine for the automobile aluminum alloy hub is simple in structure, high in automation degree, and free of manual carrying of the hub casting; the automobile aluminum alloy hub can be automatically clamped, moved, cooled, turned over and discharged in production, so that the automation level of a hub production device can be improved.

Description

Technical field [0001] The invention relates to an automobile wheel hub production equipment, in particular to a cooling manipulator of an automobile aluminum alloy wheel hub die casting machine. Background technique [0002] In the existing casting equipment, after leaving the mold, the wheel casting falls on a pallet that can swing around a point. The casting worker first rotates the pallet to make the wheel casting leave the upper and lower clamping area of ​​the casting equipment, and then clamp the wheel casting with pliers. The edge removes it from the tray and places it in the sink to soak in water to cool it. After the hub casting has cooled, the caster uses pliers to clamp the hub casting again to remove it from the sink and place it on the subsequent workbench. In this way, the hub casting The process of soaking in water is completely performed manually, and the casting workers need to be in close contact with the high-temperature hub castings during the transportation ...

AI Technical Summary

Problems solved by technology

The wheel hub automatic soaking device has a simple structure, saves time and effort in handling the wheel hub castings, effectively solves potential safety hazards, and improves the production efficiency of the wheel hub; however, the device also has the following defects: (1) The grabbing mechanism in the manipulator Using two independent first clamping arms and second clamping arms to move toward each other along the clamping shaft, the manipulator can grab or loosen the wheel hub castings in the tray or in the soaking tank, due to the first clamping arm and the second The two clamping arms are independent of each other, which can easily cause the movement of the first clamping arm and the second clamping arm to be out of sync, and cause damage to the hub during the clamping process; (2) The movement of the manipulator is driven by a single chain, Due to the heavy weight of the manipulator after clamping the hub, the use of a single chain drive may easily cause the manipulator to shake during the movement process, and the manipulator may swing to both sides during the movement process, which may easily cause position deviation when the manipulator approaches the positioning detection switch; (3) Cool the hub casting by driving the soaking platform down. Since the cooling of the hub generally takes 10-20 minutes, it means that during this cooling time, the manipulator must always clamp the hub and cannot perform other actions. The cooling efficiency is reduced, and the power requirement for moving the water soaking platform is high, which may easily cause cooling water to overflow; (4) It is necessary to set up an additional material receiving mechanism to transport the wheel hub to the bottom of the manipulator first, resulting in complicated equipment and increased equipment costs
