The above cleaning mechanism can only clean the iron filings in the T-slot, and the iron filings on the surface of the workbench cannot be automatically cleaned. Moreover, the cleaning of iron filings by only using a nozzle is not clean enough. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an automatic iron filings cleaning device for a work surface, which can automatically clean the work surface.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a device for automatically cleaning iron chips from a work surface, comprising a chip guard plate arranged on the work surface and a driving mechanism arranged on one side of the work surface and used to drive the chip guard plate to move back and forth; both ends of the chip guard plate extend out of the work surface to form an extension, the driving mechanism acts on the extension, the side of the work surface is provided with a guide rail, and the extension slides with the guide rail; the lower end of the chip guard plate is provided with a scraper plate that fits the work surface, and one side of the chip guard plate is provided with a plurality of high-pressure nozzles facing the work surface. Principle of the utility model: After the workpiece is processed, the workpiece is removed, and the chip guard plate is driven by the driving mechanism to move on the work surface. During the movement of the chip guard plate, the scraper plate and the high-pressure nozzle are used to clean the iron chips on the work surface. After the cleaning is completed, the chip guard plate is reset under the action of the driving mechanism to make room for the workpiece to be fixed and wait for the next cleaning work.

[0005] As an improvement, two chip guard plates are provided on the work surface, and driving mechanisms are provided on both sides of the work table respectively. The two driving mechanisms drive the two chip guard plates to move in opposite directions, and the initial position of the chip guard plates is in the middle of the work surface.

[0006] As an improvement, the driving mechanism is a cylinder, a hydraulic cylinder, a gear rack or a screw nut mechanism.

[0007] As an improvement, the lower end of the chip guard plate is bent into an L-shaped portion, and the scraper plate and the high-pressure nozzle are arranged on the L-shaped portion.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] During the movement of the chip guard plate, the scrapers and high-pressure nozzles are used to clean the iron chips on the work surface. The cleaning effect is good, no manual intervention is required, and the degree of automation is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] like Figures 1 to 4 As shown, a device for automatically cleaning iron chips from a worktable surface can be used for machining machine tools, and includes a chip guard plate 2 arranged on the surface of the worktable 1 and a driving mechanism 3 arranged on one side of the worktable 1 and used to drive the chip guard plate 2 to move back and forth. The left and right ends of the chip guard plate 2 extend out of the surface of the worktable 1 to form an extension 21, and the extension 21 is bent into an L shape to enhance its structural strength. The lower end of the extension 21 extends downward to the side of the worktable 1, and the driving mechanism 3 acts on the extension 21; the side of the worktable 1 is also provided with a guide rail 6, and the groove or slider on the extension 21 is slidably matched with the guide rail 6, and the guide rail 6 can improve the stability of the movement of the chip guard plate 2. The lower end of the chip guard plate 2 is bent into an L-shaped portion to improve the structural strength of the chip guard plate 2. The L-shaped portion is provided with a scraper plate 5 that fits the surface of the workbench 1 and a plurality of high-pressure nozzles 4 arranged in a line above the scraper plate 5. The scraper plate 5 is screwed to the chip guard plate 2. In this embodiment, the surface of the workbench 1 is a plane, and the workpiece is fixed on the surface of the workbench 1. The driving mechanism 3 is a cylinder, a hydraulic cylinder, a gear rack or a screw nut mechanism. In this embodiment, a cylinder is used as the driving cylinder. Figure 3 , 4As shown, in order to improve production efficiency, the rotary worktable 1 of this embodiment is arranged as a double station, that is, two chip guard plates 2 are provided on the surface of the worktable 1, and driving mechanisms 3 are respectively provided on both sides of the worktable 1. The two driving mechanisms 3 drive the two chip guard plates 2 to move in opposite directions. The initial position of the chip guard plate 2 is in the middle position of the worktable 1 surface. The middle chip guard plate 2 divides the worktable 1 surface into two processing stations 11. One of the processing stations 11 is in processing, and the other processing station 11 is in workpiece 7 clamping. After the workpiece 7 is processed, the corresponding chip guard plate 2 moves outward to clean the iron chips on the worktable 1 surface.

[0016] Principle of the utility model: After the workpiece is processed, the workpiece is taken away and the driving machine is used to drive the chip guard plate 2 to move on the workbench 1. During the movement of the chip guard plate 2, the scraper plate 5 and the high-pressure nozzle 4 are used to clean the iron chips on the workbench 1. After the cleaning is completed, the chip guard plate 2 is reset under the action of the driving mechanism 3, freeing up space for the workpiece to be fixed and waiting for the next cleaning work.
