[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1-5 As shown, a safety protection device for a bench drilling machine includes a bench drill 1 provided with a workbench 2, and also includes a protective cover 3 provided with a storage box 33, and the two are clamped with the workbench 2, and a slide bar 31 is provided on the side of the protective cover 3 to slide with the workbench 2;

[0027] The slide bar 31 is provided with a locking rod 32 which is plugged and locked with the workbench 2;

[0028] A scraper 34 is provided in the protective cover 3 , and the scraper 34 cooperates with the end surface of the workbench 2 for scraping.

[0029] Specifically, the workbench 2 is installed on the bench drill 1, and a clamping member can be provided on the workbench 2 to fix the parts to be processed. A fixedly installed cover is provided on the back of the bench drill 1 to intercept scattered waste chips so that the waste chips remain on the surface of the workbench 2 to be collected. This is the prior art and will not be elaborated here.

[0030] Furthermore, the cover body of the protective cover 3 on the upper surface of the workbench 2 is transparent, which is convenient for checking the processing status of the parts. Two slide bars 31 are fixedly installed on the inner side of the protective cover 3 which is "U"-shaped when viewed from above, and the side wall of the workbench 2 is provided with a groove for the slide bars 31 to slide into.

[0031] Furthermore, the end of the scraper 34 made of elastic metal sheet is in a barb shape, and the workbench 2 is located between the storage box 33 and the scraper 34 .

[0032] By sliding the slide bars 31 on both sides of the protective cover 3 into the grooves on the workbench 2, and with the workbench 2 being used as an auxiliary clamping limiter by the storage box 33 and the scraper 34, the protective cover 3 can be stably restricted up and down and left and right during the installation process. Then, the locking rod 32 on the slide bar 31 is inserted into the workbench 2 again, so that the protective cover 3 can be stably installed on the workbench 2 and shield the working area of ​​the workbench 2 to prevent the waste chips generated during processing from scattering and injuring the staff. When removing the processed parts on the workbench 2, the protective cover 3 is slid out to allow the scraper 34 to scrape the waste chips on the surface of the workbench 2 into the storage box 33 for storage, thereby reducing the accumulation of waste chips on the workbench 2 and collecting the waste chips in a centralized manner to reduce pollution to the environment.

[0033] As an embodiment further provided by the present invention, an elastic member is provided on the locking rod 32, and a plug hole is provided on the side of the workbench 2. In a default state, the elastic member enables the locking rod 32 to be inserted into the plug hole.

[0034] Specifically, the elastic member is a tension spring, and a ring is provided at the end of the locking rod 32 to facilitate pulling by fingers.

[0035] The slide bar 31 is retracted by pulling the lock rod 32 so that the slide bar 31 slides into the slideway, accompanied by deformation of the elastic member. When the lock rod 32 reaches a predetermined position, the elastic member is reset so that the lock rod 32 is inserted into the insertion hole, thereby locking and fixing the protective cover 3.

[0036] As another embodiment further provided by the present invention, a groove 21 is provided on the workbench 2 , and a plurality of partition bars 22 are fixedly installed in the groove 21 .

[0037] Specifically, the spacer bar 22 is a prior art on the workbench 2 and will not be described in detail herein, and the groove 21 is in a concave state.

[0038] The groove 21 is used to gather the waste chips that fall onto the workbench 2 to the depressed lower position, so that the scraper 34 can scrape the waste chips gathered at the depressed position into the storage box 33 .

[0039] As another embodiment further provided by the present invention, a scraping groove 23 cooperating with the scraper 34 is provided on the partition bar 22 .

[0040] Specifically, the scraping groove 23 is arranged on the path of the scraper 34 to facilitate the end of the scraper 34 to scrape the waste, and the length of the scraper 34 and the storage box 33 is less than the length of the slide bar 31, and the width of the storage box 33 is greater than the width of the scraper 34.

[0041] The protective cover 3 slides away from the workbench 2 but does not detach, so that the slide bar 31 remains connected to the slideway, and at this time the scraper 34 completely scrapes the waste chips in the scraping groove 23 off the workbench 2 and makes the waste chips fall into the storage box 33.

[0042] As another embodiment further provided by the present invention, a notch is provided on the end surface of the protective cover 3, and a door panel 35 is hingedly provided in the notch.

[0043] Specifically, a torsion spring is provided at the hinged position of the door panel 35, and the torsion spring closes the gap of the door panel 35 in a default state.

[0044] By hingedly setting the door panel 35, when the protective cover 3 is not far away from the workbench 2, the worker can put his hand through the gap and cause the door panel 35 to deflect into the protective cover 3, so that the worker can adjust the position of the parts on the workbench 2 and perform other operations.

[0045] As another embodiment further provided by the present invention, an air cavity 36 is opened on the side of the protective cover 3 , and an air outlet 373 with a port facing the groove 21 is arranged at a lower position of the air cavity 36 .

[0046] Specifically, an air inlet 372 is provided on the outside of the protective cover 3, and a one-way valve sheet is provided in the air inlet 372 and the air outlet 373 (the installation method and the sealing method are both existing technologies and are not described here), so that the air cavity 36 has the function of pumping in and discharging gas, and the port of the air outlet 373 is inclined downward toward the groove 21.

[0047] The air in the air cavity 36 is blown into the groove 21 through the downwardly inclined air outlet 373 , so that the waste chips on the high edge of the groove 21 can be blown to the low position, making it convenient for the scraper 34 to scrape and collect the waste chips.

[0048] As another embodiment further provided by the present invention, a plug 37 is slidably disposed in the air cavity 36 , and a contact member 371 that is pushed and moved by the door plate 35 is disposed on the plug 37 .

[0049] Specifically, a spring and a telescopic rod (with damping arranged therein, which is a prior art and will not be described in detail here) are fixedly installed between the plug 37 and the air cavity 36, and a hole is also opened on the side wall of the air cavity 36 above the sliding of the plug 37 to provide gas flow on the back side of the piston movement, and a rubber ring is also fixedly sleeved on the plug 37.

[0050] Furthermore, the contact member 371 is a "Z"-shaped rod, which makes it easy for the end of the door panel 35 to push the plug 37 to slide, and the sliding has a larger stroke to ensure the amount of air pumped in / out.

[0051] Furthermore, a vertical hole connected to the air cavity 36 is opened on the side wall of the protective cover 3, and a rubber membrane is fixedly installed in the vertical hole, and the rubber membrane wraps the touch-receiving member 371, so that the rubber membrane can keep the air cavity 36 sealed during the up and down movement of the touch-receiving member 371.

[0052] When the door panel 35 deflects into the protective cover 3, the end of the door panel 35 pushes the contact member 371 to move upward, so that the air inlet 372 is opened during the upward sliding of the plug 37, and the outside air is pumped into the air cavity 36. When the door panel 35 is reset, the plug 37 slides down to open the air outlet 373, so that the protective cover 3 is kept covered by the door panel 35 during the blowing process, reducing the risk of waste chips being blown up by the air flow and escaping from the gap.

[0053] Working principle: by pulling the locking rod 32 to retract the slide bar 31, accompanied by the deformation of the elastic part, the slide bars 31 on both sides of the protective cover 3 are slid into the grooves on the workbench 2, and the workbench 2 is used as an auxiliary clamping limit by the storage box 33 and the scraper 34, so that the protective cover 3 can be stably restricted up and down and left and right during the installation process, and then the locking rod 32 is inserted into the workbench 2, so that the protective cover 3 can be stably installed on the workbench 2 and shield the working area of ​​the workbench 2. When the processed parts on the workbench 2 are removed, the protective cover 3 is slid out to allow the scraper 34 to scrape the waste chips on the surface of the workbench 2 into the storage box 33 for storage, thereby reducing the accumulation of waste chips on the workbench 2.

[0054] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
