An automatic cleaning mechanism for CNC gear hobbing machines

Abstract

This utility model relates to an automatic cleaning mechanism for a CNC gear hobbing machine. The collecting device includes a collecting component installed inside the CNC gear hobbing machine body for left and right movement. A grid for restricting the cleaning device is fixedly installed inside the collecting component. The cleaning device includes a draining component installed inside the collecting device for automatically discharging coolant. A connecting pipe is provided at the bottom end of the draining component. When the connecting pipe generates suction controlled by an external water pump, the coolant in the collecting tank can be discharged along the fixed ring into the funnel and reused along the connecting pipe. At the same time, the float and the T-shaped limiting plate move in the limiting groove to keep the fixed ring always above the coolant surface in the collecting tank. After the coolant in the collecting tank is automatically discharged, the collecting tank can be removed from the CNC gear hobbing machine body by the handle, and the iron filings in the collecting tank can then be cleaned and discharged.

Description

Technical Field

[0001] This utility model relates to the field of CNC gear hobbing machine technology, and in particular to an automatic cleaning mechanism for CNC gear hobbing machines. Background Technology

[0002] When processing cylindrical gears and worm gears in batches, small batches, and single pieces, CNC hobbing machines are required. CNC hobbing machines use radial feed to cut ordinary worm gears. The adjustment and processing methods for machining splined shafts and sprockets are the same as when machining cylindrical spur gears. Currently, existing CNC hobbing machines generate a large amount of iron filings that mix with the coolant during production, making automatic cleaning of this mixture inconvenient. For example, in an automatic cleaning mechanism for a CNC hobbing machine as described in Chinese patent application CN202120503103.5, a collection box is fixedly installed on the inner bottom wall of the base frame. A support plate is fixedly connected inside the collection box. A vacuum cleaner is fixedly connected to the top of the support plate. The vacuum cleaner has suction pipes extending to the top of the base frame fixedly connected to its left and right input ends, and an outlet pipe penetrating the support plate is fixedly connected to its output end.

[0003] However, when using a vacuum cleaner to absorb and clean the iron filings in the collection box, the lack of a device to separate the iron filings and coolant means that the vacuum cleaner will clean both at the same time, resulting in a waste of coolant; thus, it is not convenient to reuse the iron filings and coolant. Utility Model Content

[0004] To address the problem mentioned in the background art—that the lack of a device to separate iron filings and coolant in the collection box leads to the vacuum cleaner cleaning both simultaneously, resulting in coolant waste and hindering the reuse of both—this invention provides the following technical solution:

[0005] An automatic cleaning mechanism for a CNC gear hobbing machine includes a CNC gear hobbing machine body. A protective cover is provided at the top of the CNC gear hobbing machine body to protect the CNC gear hobbing machine body. A collection device for collecting iron filings and coolant is provided inside the CNC gear hobbing machine body. A cleaning device for automatically cleaning and discharging the coolant is provided inside the collection device.

[0006] The collection device includes a collection component installed inside the CNC gear hobbing machine for left and right movement, and a grid for restricting the cleaning device is fixedly installed inside the collection component.

[0007] The cleaning device includes a drain assembly installed inside the collection device for automatically draining the coolant, and a connecting pipe is provided at the bottom end of the drain assembly.

[0008] Furthermore, the collecting device includes a collecting box disposed within the body of the CNC gear hobbing machine for collecting iron filings and coolant, and a slider for restricting the collecting box is fixedly installed at the bottom end of the collecting box.

[0009] Furthermore, a handle for driving the collection box to move is fixedly installed on the left end of the collection box, and a limiting groove for restricting the drainage assembly is opened on the left end of the collection box cavity.

[0010] Furthermore, the drainage assembly includes a fixed ring disposed in a collection tank, a funnel for communicating with a connecting pipe is fixedly installed at the bottom end of the fixed ring, fixed plates are fixedly installed at the front and rear ends of the fixed ring, a float for floating the fixed ring in the collection tank is fixedly installed at the bottom end of the fixed plate, and a limiting plate for moving up and down in a limiting groove is fixedly installed on the ring body of the fixed ring.

[0011] Furthermore, the top of the CNC gear hobbing machine body is provided with a rotating disk for placing the cylinder, and the top of the rotating disk is fixedly installed with fixing bolts. The top of the CNC gear hobbing machine body is provided with a chip discharge groove for discharging iron chips and coolant into a collection box.

[0012] Furthermore, the bottom end of the CNC gear hobbing machine body is fixedly equipped with support legs for supporting the CNC gear hobbing machine body, and there are four support legs. The CNC gear hobbing machine body body is provided with a sliding groove for the slider to slide.

[0013] Furthermore, the protective cover is provided with two protective doors for opening the protective cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting up a collection device and a cleaning device, when it is necessary to separate the coolant and iron filings in the collection box, an external water pump can be used to control the suction of the connecting pipe, allowing the coolant in the collection box to be discharged into the funnel along the fixed ring and reused along the connecting pipe. At the same time, the float and the T-shaped limiting plate move in the limiting groove to keep the fixed ring always on the surface of the coolant in the collection box. After the coolant in the collection box is automatically discharged, the collection box can be removed from the CNC gear hobbing machine body by the handle, and then the iron filings in the collection box can be cleaned and discharged.
