Example 1:

the automatic chip removal bench drill shown in fig. 1 comprises a main shaft 1, a drill bit 2 and a workbench 3, wherein the workbench 3 comprises an accommodating part with an open upper part and a hollow table top 303 adapted to the top of the accommodating part; the dust collector also comprises a surrounding and blocking mechanism 5 arranged around the table-board 303 and a dust collecting device 4 communicated with the accommodating part.

The working principle is as follows:

the application provides a bench drill overall structure is the same with current bench drill, including being used for placing fixed work piece's workstation 3 for the drill bit 2 of processing work piece to and the installation and main shaft 1 etc. of controlling 2 heights of drill bit. The bench drill in this application improves the structure of the part of the table 3. As shown in the figure, the surface of the worktable 3 is hollowed to form a table top 303, and a cavity with an open upper part is formed below the table top 303 and corresponding to the table top, so as to form a containing part with a certain volume. During the use, the work piece is fixed on mesa 303, and the piece that produces in the course of working directly falls into the holding portion from the fretwork department of mesa 303, simultaneously, encloses to keep off mechanism 5 and blocks the piece that splashes, makes the piece fall into the holding portion all the time or on the mesa 303, reduces the pollution to the surrounding environment. The dust suction device 4 can collect the scraps intensively after the machining is finished, the manual participation degree of the scrap cleaning is reduced, in addition, the dust suction device 4 can also keep a working state in the machining process, the scraps generated in the machining process are collected immediately, and the cleanness of the table top 303 is kept. It is worth to be noted that when the dust suction device 4 and the drill bit 2 work simultaneously, the enclosure mechanism 5 not only limits the movement range of the fragments, but also concentrates the dust suction range in the space enclosed by the enclosure mechanism 5, and ensures the working effectiveness of the dust suction device 4.

Example 2:

in this embodiment, based on embodiment 1, in order to adapt to some situations that need to cooperate with the coolant or the cutting fluid during the operation of the table drill, the structure of the accommodating portion and the cooperation between the accommodating portion and the table top 303 are further optimized and defined.

As shown in fig. 2 and 4, the accommodating part includes an installation groove 301 and an accommodating box 302 placed in the installation groove 301, and the table surface 303 is detachably connected to the accommodating part. In this embodiment, the accommodating box 302 adapted to the table top 303 is arranged to accommodate and collect the chips generated in the machining process, and the accommodating box 302 is placed in the mounting groove 301 and kept fixed, so that the device for collecting the chips is of a detachable structure relative to the bench drill, and the accommodating box 302 can be conveniently taken down to clean the chips difficult to clean by the dust collector 4. In addition, when liquid such as coolant or cutting fluid need be cooperated in the working process of bench drill for use, when the drill bit 2 works, the liquid is poured on the workpiece and falls into the accommodating box 302 downwards, and the accommodating box 302 which is detachably placed is beneficial for workers to intensively clean the liquid because the dust suction device 4 cannot clean the liquid.

It should be noted that, in the present application, the detachable connection between the table 303 and the accommodating portion is to detach the table 303, so as to not only clean the table 303, but also expose and detach the accommodating box 302 below the table, because the mounting groove and the accommodating box 302 both belong to the accommodating portion, the table 303 and the accommodating portion are detachably connected, either a detachable connection between the table 303 and the mounting groove, or a detachable connection between the table 303 and the accommodating box 302, or a combination of the two connection methods may be adopted, as shown in fig. 2, the bottom surface of the table 303 directly contacts with the top surface of the accommodating box 302, meanwhile, a clamping groove is disposed outside the mounting groove 301, a clamping block corresponding to the clamping groove is disposed at the same position as the side edge of the table 303, and the limit on the table 303 is increased by the cooperation of the clamping block and the clamping groove, thereby maintaining the stability of the table 303 during the processing.

In addition, the mounting groove 301 illustrated in fig. 4 is a structure that is closed at the bottom and open at the top and has the same shape as the accommodating box 302, the mounting groove 301 in this embodiment is only named for placing the structure of the fixed accommodating box 302, in addition, the mounting groove 301 may also be provided in a through hole shape, the edge of the top surface of the accommodating box 302 extends outwards, and the surface of the mounting groove 301 is in contact with the bottom surface of the extending part of the edge of the accommodating box 302, so that the mounting groove can be detachably fixed.

Example 3:

this example was further optimized on the basis of example 1 or 2.

As shown in fig. 4, the enclosure mechanism 5 is enclosed by a first enclosure plate 501 and a second enclosure plate 502 to form a frame shape, the first enclosure plate 501 is fixedly connected with the accommodating portion, one end of the second enclosure plate 502 is hinged to the first enclosure plate 501, and the other end of the second enclosure plate 502 is detachably connected to the first enclosure plate 501. The enclosure mechanism 5 in this embodiment is configured as an openable structure formed by enclosing and connecting a fixed portion and a movable portion, that is, the first enclosure plate 501 is kept in a fixed state, the second enclosure plate 502 hinged thereto is movable to open or close the enclosure mechanism 5, and the openable configuration of the enclosure mechanism 5 is convenient for cleaning up the residual debris of the accommodating portion.

In this embodiment, preferably, the first surrounding baffle 501 and the second surrounding baffle 502 are detachably connected through an elastic snapping slot 503 and a snapping strip 504 adapted to the elastic snapping slot 503. In this embodiment, an example is provided for a structure that the first surrounding baffle 501 and the second surrounding baffle 502 are detachably connected, as shown in fig. 3, an elastic buckling groove 503 is disposed at an end of the first surrounding baffle 501, a buckling strip 504 is disposed at an end of the second surrounding baffle 502, the buckling strip 504 is buckled in the elastic buckling groove 503 to enable the surrounding baffle mechanism 5 to be in a surrounding state, and when the surrounding baffle mechanism 5 needs to be opened, the buckling strip 504 is directly taken out from an opening of the elastic buckling groove 503 by using the elastic buckling groove 503 for elastic deformation. It should be noted that the arrangement of the elastic latching groove 503 and the latching bar 504 is a way to realize the latching-type detachable connection, in the implementation, the elastic latching groove 503 can also be connected with the second baffle 502, and correspondingly, the latching bar 504 is connected with the first baffle 501.

Example 4:

in this embodiment, the fitting of the dust collector 4 and the accommodating portion is further optimized based on embodiment 2.

As shown in fig. 4, the dust suction device 4 includes a dust suction power mechanism and a dust suction pipe connecting the accommodating portion and the dust suction power mechanism, and holes corresponding to the dust suction pipe are formed in the side surfaces of the mounting groove 301 and the accommodating box 302. The dust suction device 4 of the embodiment is connected to the accommodating box 302 through a dust suction pipe, so that the dust suction device 4 can be used to remove the debris in the accommodating box 302 at one time after the bench drill is machined, and the dust suction device 4 can also keep working synchronously during the bench drill machining process, and the debris is sucked out of the space of the accommodating box 302 after passing through the hollow part of the table top 303.

Example 5:
