Detailed Description
Referring to fig. 1, the present invention provides a workbench of a numerical control machine tool, which includes a workbench body 1 and a cleaning mechanism.
Specifically, the cleaning mechanism includes a cleaning baffle 2 and a cleaning assembly 3.
The cleaning baffle 2 is arranged on the peripheral outer side surface of the workbench body 1 in a surrounding mode, the height of the cleaning baffle is 3 times larger than that of the workbench body 1, and a chip removal port 21 is formed in the cleaning baffle.
The cleaning assembly 3 includes a dust suction duct 31 and a dust collector 32. The dust suction inlet of the dust collector 32 is communicated with the scrap discharging port 21 through the scrap suction pipeline 31, the connection part between the dust suction inlet and the scrap suction pipeline 31 is connected in a sealing way, and the connection part between the scrap discharging port 21 and the scrap suction pipeline 31 is connected in a sealing way.
Therefore, when the numerical control machine tool enters a machining state, the dust collector 32 is started, so that the dust collector 32 can absorb metal chips, and the metal chips of the workbench body 1 can be cleaned. After the numerical control machine tool has finished machining, the dust collector 32 can be allowed to continue working for a period of time, and the dust collector 32 can be closed until metal chips on the workbench body 1 are removed.
As a more preferable technical solution, referring to fig. 2, one end of the powder scrap suction pipe 31 connected with the scrap discharge port 21 is a metal pipe a, and an electromagnetic assembly is arranged around the periphery of the metal pipe a, so as to ensure that the metal scraps are adsorbed on the electromagnet under the magnetic force of the electromagnet in the process that the dust collector 32 sucks the metal scraps or sucked into the dust collector 32 along a certain direction, further limit the recovery track of the metal scraps and avoid the metal scraps from floating due to the suction force of the dust collector 32 in the recovery process, thereby facilitating cleaning; the electromagnetic assembly comprises an electromagnet 33, a power supply, a control switch and a controller which are sequentially connected in series and form a loop; the controller is electrically connected with the control switch and controls the on-off of the electromagnet 33 through the control switch.
In order to improve the intelligence of the whole cleaning mechanism, preferably, the controller is further electrically connected with the dust collector 32, and controls the start and stop of the dust collector 32 according to an externally input numerical control machine tool working signal.
The control of the vacuum cleaner 32 and the control switch by the controller comprises the following steps:
s1: initializing all data;
s2: receiving a numerical control machine tool working signal input from the outside; judging whether the current numerical control machine tool is in a processing state or not according to the working signal of the numerical control machine tool, if so, controlling the dust collector 32 to be started, simultaneously controlling the control switch to be closed, recording the closing time of the control switch in real time, and repeatedly and sequentially executing the steps S3-S4; otherwise, keeping the dust collector 32 closed and the control switch off; the method for acquiring the working signal of the numerical control machine tool can be as follows: by associating the controller of the invention with the corresponding part of the numerical control machine tool, the numerical control part of the numerical control machine tool immediately sends an opening instruction to the controller of the invention as long as the numerical control machine tool enters a processing working state, otherwise, the controller does not receive any effective signal sent by the numerical control part;
s3: judging whether the closing time is equal to or greater than the preset adsorption time, if so, controlling the control switch to be switched off, and recording the switching-off time of the control switch in real time; otherwise, keeping the current state;

At this time, the running time of the electromagnet 33 from the exhaust port 21 to the dust collection inlet can be set according to the speed of the reciprocating driving mechanism 34 driving the electromagnet 33 to move and the stroke required to move, and the running time is stored in the controller, and the controller can control the time of each work of the reciprocating driving mechanism 34 according to the running time, so that the electromagnet 33 can be stopped running at the exhaust port 21 or at the dust collection inlet.
In this embodiment, the reciprocating driving mechanism 34 is a linear reciprocating driving mechanism, and may be an electric push rod.
To minimize the recycling path to further improve the cleaning efficiency, it is preferable that the metal pipe is a straight pipe and its axis is parallel to the top surface of the table body 1, as shown in fig. 3.
In the present embodiment, in order to make the metal chips more easily discharged from the chip discharge port 21, further improve the cleaning efficiency and improve the cleaning effect, it is preferable that the inner wall surface of the bottom end of the opening of the cleaning baffle 2 be flush with the top surface of the table body 1.

a1: initializing all data;
a2: receiving a numerical control machine tool working signal input from the outside; judging whether the current numerical control machine tool is in a machining state or not according to the working signal of the numerical control machine tool, if so, controlling the control switch to be closed, recording the closing time of the control switch in real time, and repeatedly and sequentially executing the steps A3-A4; otherwise, keeping the control switch disconnected;
a3: judging whether the closing time is equal to or longer than the preset adsorption time, if so, controlling the reciprocating driving mechanism 34 to start to drive the electromagnet 33 to move towards the direction of the end position switch; otherwise, keeping the current state;
