Description

Technical Field

[0001] This utility model relates to the technical field of machining center worktables, specifically a worktable used in machining centers. Background Technology

[0002] Machining centers mainly refer to milling machines. Milling machines are machine tools that use milling cutters to process various surfaces on workpieces. They are a wide range of machine tools. In a machining center, during the milling process, a spray nozzle is attached to the side of the milling cutter to continuously spray coolant onto the workpiece to cool it and allow the milling cutter to process the workpiece better. While the workpiece is being processed by the milling cutter, waste chips are constantly being cut off and fall onto the worktable and the grooves on the worktable. A large amount of waste chips are washed away and accumulate on the bottom surface of the outer protective shell. Therefore, after each processing, the operator needs to use a broom to enter the outer protective shell to clean up these waste chips.

[0003] Chinese utility model patent, authorized announcement number CN205571921U, announcement date September 14, 2016, announces a workbench for a machining center. The key technical points of the solution are: it includes a workbench body, a surrounding wall, and a collection trough formed between the surrounding wall and the workbench body. A filter screen is installed in the collection trough, and a liquid outlet is provided in the collection trough. A flexible hose is connected to the liquid outlet, and the other end of the hose is connected to a storage tank. In the aforementioned prior art, the collection trough is located between the workbench body and the surrounding wall. Waste debris on the workbench body flows into the collection trough along with the coolant. After entering the collection trough, the waste debris is filtered and collected on the filter screen. After each machining operation, the operator needs to use a broom and enter the outer protective shell to clean the waste debris, which is relatively cumbersome.

[0004] Therefore, we propose a worktable for machining centers. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This workbench for machining centers features a waste chip trough and a guide ramp. Waste chips generated during machining are flushed from the workbench body to the guide ramp by coolant, then flow into a filter box through a channel. After being filtered by a filter belt, the waste chips are scraped off the filter belt by a scraper and flow into the waste chip trough. When the waste chips in the waste chip trough accumulate to a certain level, the chip removal motor is activated to drive the propeller blades to rotate, discharging the waste chips through the discharge port. This allows for convenient collection and unified processing of the waste chips generated during machining, and the operation is simple and convenient.

[0015] The workbench used in the machining center is equipped with a splash guard. When the mixture of waste chips and coolant enters the filter box through the channel, the splash guard prevents the coolant from splashing and confines the waste chips to the filter screen belt. The coolant is then filtered through the filter screen belt and then flows back to the cutting fluid reservoir via the connecting pipe. Attached Figure Description

By setting up the waste chip trough 7 and the guide ramp 4, the waste chips generated during the processing are flushed from the workbench body 5 to the guide ramp 4 by the coolant, and then flow into the filter box 3 through the channel 2. After being filtered by the filter screen belt 9, the waste chips on the filter screen belt 9 are scraped off by the scraper 11 and flow into the waste chip trough 7. When the waste chips in the waste chip trough 7 accumulate to a certain extent, the chip removal motor 13 is started to drive the propeller blade 12 to rotate and discharge the waste chips through the discharge port 14. This makes it convenient to collect and process the waste chips generated during processing. The operation is simple and convenient.

[0023] A scraper 11 is fixedly installed on the top rear side of the filter box 3. The top of the scraper 11 slides in contact with the bottom of the filter belt 9.

The filtered coolant is filtered again through the filter plate 10 and then flows back to the cutting fluid storage tank through the connecting pipe 15.

[0024] Working principle:

[0025] The waste chips generated during the processing are flushed from the worktable body 5 to the guide ramp 4 by the coolant, and then flow into the filter box 3 through the channel 2. After being filtered by the filter screen belt 9, the waste chips on the filter screen belt 9 are scraped off by the scraper 11 and flow into the waste chip trough 7. When the waste chips in the waste chip trough 7 accumulate to a certain extent, the chip removal motor 13 is started to drive the propeller blade 12 to rotate and discharge the waste chips through the discharge port 14. This facilitates the collection and unified treatment of the waste chips generated during processing. The operation is simple and convenient. When the mixture of waste chips and coolant enters the filter box 3 through the channel 2, the splash guard 16 prevents the coolant from splashing and at the same time confines the waste chips on the filter screen belt 9. The coolant is then filtered by the filter screen belt 9. After being filtered again by the filter plate 10, the coolant flows back to the cutting fluid storage tank through the connecting pipe 15.
