Description

Technical Field

[0001] The utility model belongs to the technical field of bench-type drilling machines, and in particular relates to a bench-type drilling machine base which is convenient for chip removal. Background Art

[0002] The bench drilling machine is called bench drill for short. It refers to a small drilling machine that can be placed on the workbench with the spindle arranged vertically. The drilling diameter of the bench drilling machine is generally below 13 mm and not more than 25 mm. The bench drilling machine is mainly used for drilling, reaming, boring, tapping, and scraping surfaces of small and medium-sized parts. It is used in processing workshops and mold repair workshops. Compared with similar machine tools at home and abroad, it has the characteristics of low horsepower, high rigidity, high precision, good rigidity, easy operation, and easy maintenance.

[0003] When drilling holes in workpieces, the drill bit of a benchtop drilling machine generates a large amount of debris. A small portion of these debris remains on the workbench, while most of them fall onto the base below the workbench or splash around the base. These randomly scattered debris are difficult to collect together, so they are also difficult to clean. In the prior art, in order to collect the debris generated by the drilling machine during operation and prevent the debris from being scattered everywhere, a negative pressure suction device for the debris is added to the drilling machine, and the attracted debris is uniformly collected in a collection box. When the drilling machine is operating, the collection box needs to be placed next to the drilling machine, and the debris collected by the negative pressure suction device enters the collection box. However, the collection box is an external additional device of the drilling machine, and being located next to the drilling machine may interfere with the processing operations on the drilling machine.

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] Example 1

[0047] A benchtop drilling machine base for easy chip removal, comprising: a base 1, a negative pressure suction component;

[0048] like Figure 1 As shown, the base 1 is arranged at the lower end of the main shaft 2 of the bench-type drilling machine, and the lower end of the main shaft 2 is arranged on the right side of the upper surface of the base 1; a workbench 3 is arranged on the main shaft 2, and the workbench 3 is a processing platform of the drilling machine, and the drilling operation of processing the workpiece is placed on the workbench 3 for execution; the upper end of the main shaft 2 is arranged with a drill driving assembly, and a drill mounting seat and a drill are arranged below the drill driving assembly; the bench-type drilling machine is an existing product, and the structures of the above-mentioned base 1 and main shaft 2, main shaft 2 and workbench 3, and drill driving assembly and the connection relationship between the structures belong to the existing design of the existing bench-type drilling machine, and this embodiment mainly aims at the design improvement of the base 1 of the bench-type drilling machine, so other components are not described in detail.

[0049] The workbench 3 of the bench-top drilling machine is arranged above the base 1. Part of the debris generated on the workbench 3 will fall on the base 1, and the other part will fall on the area outside the base 1; but no matter which area the debris falls on, it is not collected uniformly, which increases the workload of cleaning in the later process of cleaning the debris.

[0050] In this embodiment, a negative pressure suction component is provided to attract and uniformly collect the debris to prevent the debris from flying around; the negative pressure suction component includes: a dust collecting pipe 6, a negative pressure device, a diffuser cover and a negative pressure device connecting pipe 602;

[0051] A buckle is provided on the spindle 2 of the drilling machine, and the tube body of the dust collecting tube 6 is detachably fixed in the buckle, and the dust collecting tube 6 can be fixed on the spindle 2 by means of the buckle; the upper end of the dust collecting tube 6 is connected to a diffuser cover, and the diffuser cover increases the entrance of the debris channel, so that the debris can enter the dust collecting tube 6 more easily; one end of the dust collecting tube 6 connected to the diffuser cover is set as a suction inlet end; the lower end of the dust collecting tube 6 is set as a discharge outlet, and the collected debris is discharged from the discharge outlet; the dust collecting tube 6 forms a low pressure in the tube, and utilizes the pressure difference between the inside and the outside to collect the debris Sucked into the dust collecting pipe 6; however, the discharge port of the dust collecting pipe 6 needs to discharge the debris and cannot be used to connect the negative pressure device; therefore, a negative pressure device connecting pipe 602 for connecting to the negative pressure device can only be set on the side wall of the dust collecting pipe 6; one end of the above-mentioned negative pressure device connecting pipe 602 is connected to the outer wall of the dust collecting pipe 6 and communicates with the inside of the dust collecting pipe 6; the other end of the negative pressure device connecting pipe 602 is connected to the negative pressure device; in this way, the negative pressure device exhausts the air in the dust collecting pipe 6 through the negative pressure device connecting pipe 602, so that an air pressure difference is formed inside and outside the pipe; the suction and collection of the debris is completed.

[0052] One end of the dust collecting pipe 6 connected to the expansion housing serves as an inlet end for the debris and should be arranged beside the workbench 3 so that when the drill bit processes the workpiece on the workbench 3, the debris generated can be absorbed by the dust collecting pipe 6 at the fastest speed.

[0053] As a preferred embodiment, the upper part of the dust collecting pipe 6, that is, the part close to the expansion mouth, is set as a gooseneck tube, which can be bent and adjusted in direction at will, and can be maintained after adjustment; this makes it convenient to adjust the expansion mouth to the side close to the workbench 3; and it is the position that is most conducive to the absorption of debris.

[0054] The debris output from the discharge port of the dust collecting pipe 6 needs to be collected uniformly, so a collection box is needed; a separate collection box is set up beside the drilling machine, which may interfere with the workpiece processing based on the drilling machine;

[0055] like Figure 2 As shown, in this embodiment, the base 1 of the drilling machine is set to a structure with a certain height; the interior of the base 1 is set to a hollow structure, and the upper surface of the base 1 is set to an open structure, so that the base 1 is equivalent to a dust box with a certain volume; the discharge port of the dust collecting pipe 6 is connected to the opening structure on the upper surface of the base 1; in this way, the debris absorbed by the dust collecting pipe 6 is directly output from the discharge port of the dust collecting pipe 6 to the inside of the base 1; and is uniformly collected by the base 1.

[0056] In this embodiment, the negative pressure suction component and the dust box formed by the base 1 are integrated with the drilling machine itself; some additional devices or additional structures are reduced; and the drilling machine can be prevented from being disturbed by these additional devices during the processing.

[0057] Example 2

[0058] Based on Example 1, in Example 1, most of the debris generated near the workbench 3 can be absorbed by the dust collecting pipe 6 and then enter the base 1 to be collected. However, it is inevitable that a small amount of debris is not absorbed by the dust collecting pipe 6, and this part of the debris may fall directly from the workbench 3; in the process of falling, this part of the debris may not only fall directly into the base 1, but also fly to the area outside the base 1.

[0059] like Figure 3 As shown, in this embodiment, a detachable baffle plate 4 is provided on the front and rear sides of the base 1 and the left side of the base 1; the upper edge of the baffle plate 4 is close to the workbench 3; in this way, the baffle plate 4 is used to enclose and isolate the space between the workbench 3 and the base 1; the debris falling from the workbench 3 will only fall directly into the base 1 under the action of the baffle plate 4; the debris can be prevented from flying around.

[0060] like Figure 4Two mounting slots 102 are respectively provided on the front and rear sides and the left side of the base 1; a plug-in block 401 is provided on the lower bottom edge of the enclosure plate 4, and the position of the plug-in block 401 corresponds to the mounting slot 102, and the plug-in block 401 is detachably provided in the mounting slot 102, so that the enclosure plate 4 can be detachably provided on the front and rear sides and the left side of the base 1.

[0061] Example 3

[0062] Based on the embodiment 2, since the baffle plate 4 is provided in the embodiment 2, the dust collecting tube 6 may be installed on the baffle plate 4 instead of on the main shaft 2 .

[0063] like Figure 7 As shown, buckles 601 are provided on the inner side surfaces of the baffle plates 4 on the front and rear sides; similarly, the dust collecting tube 6 is detachably fastened to the buckles 601; this makes it more convenient to face the lower end discharge port of the dust collecting tube 6 to the opening structure on the base 1.

[0064] Example 4

[0065] Based on Example 1, in Example 1, an opening structure is provided on the upper surface of the base 1 so that the debris coming out of the dust collecting tube 6 can enter the base 1; however, if the top of the base 1 is set to a completely open structure, the base 1 itself completely becomes a container with an opening on the top; the structure of the base 1 is completely changed.

[0066] like Figure 2 As shown, in this embodiment, the opening structure is configured as a plurality of slits 101 arranged side by side on the upper surface of the base 1; the debris coming out of the dust collecting pipe 6 falls onto the surface of the base 1 and also flows into the base 1 through the slits 101; in this way, the upper surface of the base 1 with a plurality of slits 101 can not only leak the debris into the base 1, but also place some small parts or small tools on the upper surface of the base 1.

[0067] However, it is undeniable that there may still be a small amount of debris between the leak gaps 101 and 101 , which cannot leak into the base 1 ; in this case, assistance is needed to allow it to leak into the base 1 .

[0068] like Figure 4 As shown, in this embodiment, a cleaning plate 7 is movably provided on the upper surface of the base 1; the lower bottom edge of the cleaning plate 7 should always be in contact with the upper surface of the base 1; the cleaning plate 7 moves left and right on the upper surface of the base 1, so that the debris on the upper surface of the base 1 that has not leaked into the base 1 can be cleaned into the base 1.

[0069] The connection structure between the cleaning plate 7 and the base 1 is configured as follows: a transverse leak slit 101 is provided on the upper surface of the base 1 near the front and rear sides;

[0070] A slider 701 is provided near the left and right ends of the lower bottom edge of the cleaning plate 7; the two sliders 701 are movably embedded in two horizontal slits 101; the slits 101 serve as slide rails for the movement of the cleaning plate 7 and can also allow debris to fall into the base 1.

[0071] When there are debris on the base 1 that cannot flow into the base 1 , the cleaning plate 7 only needs to be moved left and right, and the lower bottom edge of the cleaning plate 7 contacts the upper surface of the base 1 , so that the debris on the upper surface of the base 1 can be swept to the leak 101 and flow into the base 1 from the leak 101 .

[0072] As a preferred embodiment, Figure 5 As shown, the portion of the lower bottom edge of the cleaning plate 7 between the two sliders 701 is set as a bristle 702 structure; the bristle 702 structure itself is composed of a plurality of bristles; compared with the structure of the lower bottom edge of the cleaning plate 7 which is a whole piece, the bristle 702 structure has smaller movement resistance after contacting the upper surface of the base 1; in addition, the bristle 702 structure can more cleanly sweep the debris on the upper surface of the base 1 that has not leaked into the base 1 into the base 1.

[0073] Example 5

[0074] Based on Example 1, in Example 1, the debris leaked into the base 1 and collected needs to be cleaned out from the base 1 little by little during cleaning, and cannot be directly dumped; such a cleaning method is slow.

[0075] like Figure 2 As shown, an opening is provided on the left side of the base 1, and a pull-out dust box 5 is provided inside the base 1. A drawer structure is provided between the dust box 5 and the base 1; the dust box 5 can be pulled out or pushed back into the base 1 from the opening; the debris leaking into the base 1 is collected in the dust box 5. In this way, when the debris is fully collected, it is only necessary to take out the dust box 5 and clean up the debris in the dust box 5.

[0076] like Figure 4 As shown, since the dust box 5 is provided, corresponding to the second embodiment, the installation slot 102 of the baffle plate 4 installed on the left side is correspondingly provided on the left side surface of the dust box 5 .

[0077] Example 6

[0078] Based on Example 5, if the debris collected in the dust box 5 is non-recyclable, it can be dumped directly; but if it is some metal material, after the debris is collected, these metal debris can be reused after melting, so it is necessary to consider how to avoid some smaller and lighter metal debris from flying around in the dust box 5 or when the dust box 5 is taken out, causing losses.

[0079] like Figure 8As shown, in this embodiment, a magnetic plate 502 is detachably arranged below the bottom surface of the dust box 5. The bottom surface of the dust box 5 can be set to a metal material, and the magnetic plate 502 can be directly adsorbed on the bottom surface; the metal debris leaking into the dust box 5 can be condensed under the magnetic attraction of the magnetic plate 502, so that some small and light debris can be prevented from being dispersed; the condensed metal debris is also more convenient to clean and remove.
