Description

A device for cleaning iron filings from a steering gear sector shaft chamfering machine Technical Field

[0001] This utility model relates to the technical field of iron filings cleaning devices, and in particular to an iron filings cleaning device for a steering gear sector shaft chamfering machine. Background Technology

[0002] Currently, during the precision chamfering of the sector shaft of a steering gear using a chamfering machine, fine iron filings and various debris inevitably fall onto the positioning and clamping surfaces of the fixture. Due to their small size and sharpness, these scattered iron filings and debris easily scratch and wear the working surfaces of the fixture, subsequently causing clamping damage to the workpiece itself in subsequent processing stages. Once the workpiece is clamped, not only will its surface finish and precision be severely affected, failing to meet predetermined quality standards, but more importantly, this damage can also lead to inaccurate positioning of the workpiece on the automated production line, or even jamming, directly causing the entire automated line to malfunction and production to stop. This not only significantly reduces production efficiency and product quality but also increases equipment maintenance costs and the difficulty of production management. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a metal chip cleaning device for a steering gear sector shaft chamfering machine, thereby achieving the purpose of cleaning metal chips from the positioning and clamping surfaces of the fixture.

[0004] This utility model provides a device for cleaning iron filings from a steering gear sector shaft chamfering machine. The device is characterized by comprising a connecting frame and a cleaning mechanism. The cleaning mechanism is mounted on the connecting frame and includes a rotating disk and a universal direct-fire nozzle. The rotating disk has a cavity inside, and its upper wall has multiple circumferentially distributed through holes. Universal direct-fire nozzles are installed within the through holes of the rotating disk. An air inlet pipe is located on the side wall of the rotating disk, and the cavity of the air inlet pipe is connected to the cavity of the rotating disk. The air inlet pipe is connected in sequence to a solenoid valve and a compressed air tank via a pipeline.

[0005] Furthermore, the connecting frame includes a chassis, connecting columns, and a sleeve. The upper end of the chassis is connected to the sleeve through multiple connecting columns. The sleeve has a cavity with an opening at the upper end, and a cleaning mechanism is installed inside the cavity of the sleeve.

[0006] Furthermore, the chassis is provided with multiple mounting through holes evenly distributed in a circular shape, which facilitates the installation of the chassis on the chamfering machine by bolts.

[0007] Furthermore, the cavity of the sleeve is rotatably connected to the lower end of the rotating disk, and the rotating disk is connected to the power mechanism.

[0008] Furthermore, the power mechanism includes an electric motor, a drive gear, an internal gear ring, and an external gear ring. A through hole is provided on the lower end wall of the sleeve, and the electric motor is fixedly installed at the lower end of the sleeve. The motor shaft passes through the through hole of the sleeve and is fixedly connected to the gear hole of the drive gear. An internal gear ring and an external gear ring are installed at the lower end of the rotating disk. The internal gear ring is installed outside the external gear ring, and the internal and external gear rings are arranged coaxially. The drive gear is placed between the internal and external gear rings. The drive gear is an incomplete gear, and during rotation, it can sequentially mesh with the internal and external gear rings.

[0009] Compared with the prior art, the present invention has the following outstanding advantages:

[0010] 1. When using this utility model, gas is injected into the rotating plate through a compressed air tank, and the gas is sprayed out from the universal direct injection nozzle, thereby cleaning the iron filings on the positioning surface and clamping surface of the fixture.

[0011] 2. During the blowing process, the universal direct spray nozzle of this utility model starts the motor, which drives the drive gear to rotate. The drive gear rotates in sequence with the inner gear ring and the outer gear ring, driving the rotating disk to rotate back and forth, and driving the universal direct spray nozzle to rotate back and forth, thereby blowing the iron filings on the positioning surface and clamping surface of the fixture more cleanly.
