Description

Technical Field

[0001] This utility model relates to the field of bench drill cleaning technology, and in particular to a debris cleaning device for bench drills. Background Technology

[0002] A bench drill, also known as a bench drill, is a small drilling machine that can be placed on a worktable with a vertically arranged spindle. Spindle speed is typically changed by altering the position of the V-belt on the conical pulley, and spindle feed is manually operated.

[0003] During bench drill operation, the drill bit directly impacts the workpiece, generating a large amount of debris. This debris gradually accumulates on the bench drill's support platform, hindering the placement of the next workpiece.

[0004] Therefore, machining personnel need to clean up the debris frequently. If the debris is simply swept off the support table, it will accumulate around the drill press, interfering with subsequent machining. Machining personnel need to collect and clean the debris around the drill press.

[0005] In order to avoid machining debris from hindering the operation of the bench drill and affecting subsequent processing, this application proposes a debris cleaning device for bench drills, which is used to clean and collect debris during bench drill operation. Utility Model Content

[0006] In view of the shortcomings of the prior art mentioned above, the purpose of this utility model is to provide a chip cleaning device for bench drills, which solves the problem mentioned in the prior art that chips affect subsequent processing during bench drill operation.

[0007] To achieve the above and other related objectives, this utility model provides a chip cleaning device for bench drills, including a connecting support mechanism and a chip recycling mechanism. The connecting support mechanism is used to support the chip recycling mechanism. The connecting support mechanism cooperates with an external air pump to draw air from the chip recycling mechanism and suck the chips into the chip recycling mechanism.

[0008] The connecting support mechanism includes a support frame, the inside of which is provided with a cavity, and an exhaust pipe is provided on the support frame, the exhaust pipe communicating with the cavity inside the support frame;

[0009] The debris recycling mechanism includes a recycling frame, with an isolation net at the bottom of the recycling frame, and the isolation net is stacked on top of the support frame;

[0010] The top edge of the recycling frame is provided with a sealing skirt, and the top of the sealing skirt overlaps with the bottom of the external bench drill body support platform.

[0011] Preferably, two support plates are symmetrically arranged on the left and right sides of the top of the support frame, and a connecting plate is provided on the top of each support plate;

[0012] The connecting plate is connected to the bottom of the bench drill body support platform.

[0013] Preferably, the vertical height of the support plate is equal to the vertical height of the recycling frame, and the outer wall of the recycling frame is respectively attached to the inner wall of the two support plates.

[0014] Preferably, all of the connecting plates are provided with a support groove on the side facing the axis of the support frame;

[0015] The bottom of the sealing skirt fits into the top of the support groove.

[0016] Preferably, a limit baffle is provided at the rear end of the support slide to block the end of the support slide.

[0017] Preferably, the top of the sealing skirt is provided with an elastic limiting member, the elastic limiting member is elastic, and the top of the elastic limiting member overlaps with the bottom of the bench drill body support table.

[0018] Preferably, the top of the sealing skirt is provided with a telescopic groove, which is located directly below the elastic limiting member.

[0019] Preferably, the cross-section of the recycling frame is an inverted trapezoid, and the cross-section of the recycling frame is wider at the top and narrower at the bottom.

[0020] Preferably, the exhaust pipe is disposed on the side wall of the support frame.

[0021] Preferably, a filter element is provided inside the support frame, and the size of the filter element is adapted to the size of the cavity inside the support frame;

[0022] The top of the filter element overlaps with the bottom of the recycling frame.

[0023] As described above, the chip removal device for bench drills according to this utility model has the following beneficial effects:

[0024] This invention involves installing a support frame at the bottom of the bench drill body support platform, and setting an exhaust pipe on the support frame to connect with an air pump. A recovery frame is also installed on the support frame, with its top overlapping the bottom of the bench drill body support platform. During the operation of the bench drill body, the airflow drawn by the air pump carries debris through holes in the bench drill body support platform into the recovery frame for collection, preventing debris from accumulating on the support platform and thus avoiding interference with workpiece processing.

[0025] This utility model limits the recycling box by setting support plates on both sides of the top of the support frame, and further limits the recycling box by using support grooves and limiting baffles. As a result, the recycling box can be pulled out at any time during use, improving the convenience of cleaning up debris.

[0026] This invention provides elastic support to the retrieval frame by setting an elastic limiting member at the top of the sealing skirt. When the retrieval frame is inserted between the support frame and the support table of the bench drill body, the elastic limiting member provides elastic support to the retrieval frame after being compressed, thereby preventing the retrieval frame from moving during machining and achieving the effect of improving stability.

[0027] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0039] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0040] Please see Figures 1 to 7 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0041] like Figures 1-3 As shown, this utility model provides a debris cleaning device for bench drills, including a connecting support mechanism 1 and a debris recovery mechanism 2. The connecting support mechanism 1 supports the debris recovery mechanism 2. The connecting support mechanism 1 cooperates with an external air pump to draw air from the debris recovery mechanism 2 and suck the debris into the debris recovery mechanism 2.

[0042] Specifically, the connecting support mechanism 1 includes a support frame 101, which has an internal cavity. An exhaust pipe 102 is installed on the support frame 101, communicating with the internal cavity. When the exhaust pipe 102 is connected to an air pump via a conduit, the air pump draws air from inside the support frame 101, creating a negative pressure inside. At this time, the airflow acts on the surface of the support platform of the bench drill body 3 through the slots in the support platform. The negative pressure drives the external airflow to move the debris generated during the operation of the bench drill body 3.

[0043] The debris collection mechanism 2 includes a collection frame 201 for holding the collected debris. A separation net 202 is provided at the bottom of the collection frame 201, which is stacked on top of the support frame 101 to serve as an airflow channel and to isolate the debris.

[0044] A sealing skirt 203 is provided at the top edge of the recycling frame 201. The top of the sealing skirt 203 overlaps with the bottom of the support platform of the bench drill body 3, sealing the connection between the sealing skirt 203 and the bottom of the support platform of the bench drill body 3. This prevents leakage during debris extraction, which would weaken the debris removal effect.

[0045] like Figures 2-5 As shown, in some embodiments, two support plates 103 are symmetrically arranged on the left and right sides of the top of the support frame 101 to support the support frame 101 and limit the position of the recycling frame 201. Each support plate 103 has a connecting plate 104 at its top, which is connected to the bottom of the support platform of the bench drill body 3. The connecting plate 104 has through holes for bolts to pass through, and is connected by bolts to facilitate the disassembly and maintenance of the support frame 101.

[0046] like Figure 3 As shown, in some embodiments, the vertical height of the support plate 103 is equal to the vertical height of the recycling frame 201, and the outer wall of the recycling frame 201 is respectively attached to the inner walls of the two support plates 103. This ensures stability and uniqueness of the installation position after the recycling frame 201 is inserted between the support plates 103. It also effectively improves the fit between the bottom of the recycling frame 201 and the top of the support frame 101.

[0047] like Figures 3-5 As shown, in some embodiments, all connecting plates 104 of this invention have a support groove 105 on the side facing the axis of the support frame 101. The bottom of the sealing skirt 203 fits against the top of the support groove 105, thereby supporting the sealing skirt 203 through the support groove 105 and further limiting the installation of the recycling frame 201. Furthermore, the support groove 105 can form a sliding track, facilitating the insertion of the recycling frame 201.

[0048] like Figure 5 As shown, in some embodiments, a limiting baffle 106 is provided at the rear end of the support slide 105 to block the end of the support slide 105. When installing the recycling frame 201, the limiting baffle 106 provided at the end of the support slide 105 will block the sealing skirt 203, which can prevent the recycling frame 201 from being over-inserted and causing misalignment between the bottom of the recycling frame 201 and the top of the support frame 101. This improves the positioning accuracy of the lifting device assembly.

[0049] like Figure 4 and Figure 6 As shown, in some embodiments, the top of the sealing skirt 203 of this invention is provided with an elastic limiting member 204. The elastic limiting member 204 is elastic, and its top overlaps with the bottom of the support table of the bench drill body 3. The bench drill body 3 vibrates during processing. At this time, the recovery frame 201 will gradually shift under the vibration of the bench drill body 3. Therefore, the elastic limiting member 204 increases the pressure at the connection between the sealing skirt 203 and the bottom of the support table of the bench drill body 3 through elastic pressure, thereby reducing the possibility of the recovery frame 201 moving.

[0050] like Figure 6 and Figure 7 As shown, in some embodiments, the top of the sealing skirt 203 of this invention has a telescopic groove 205, which is located directly below the elastic limiting member 204. When the elastic limiting member 204 is compressed and deformed, it bends into the telescopic groove 205, thereby keeping the top of the sealing skirt 203 flush. This prevents gas leakage caused by a gap between the top of the sealing skirt 203 and the bottom of the support platform of the bench drill body 3 due to the elastic limiting member 204.

[0051] In some embodiments, the cross-section of the recycling frame 201 of this invention is an inverted trapezoid, wider at the top and narrower at the bottom. After the debris is carried into the recycling frame 201 by the negative pressure airflow, the debris will concentrate on the narrow side of the recycling frame 201 for easy recycling. At the same time, the inclined support surface can provide more contact area and more stable force, thereby improving the strength of the recycling frame 201.

[0052] like Figures 1-5 As shown, in some embodiments, the exhaust pipe 102 of this utility model is disposed on the side wall of the support frame 101. When adjusting the height of the support platform of the bench drill body 3, if the exhaust pipe 102 is installed at the bottom of the support frame 101, then the exhaust pipe 102 and the conduit connected to the exhaust pipe 102 will inevitably hinder the lifting and lowering of the support platform of the bench drill body 3, reducing the lifting and lowering stroke of the support platform of the bench drill body 3.

[0053] like Figure 4 As shown, in some embodiments, a filter element 107 is provided inside the support frame 101 of this utility model, and the size of the filter element 107 is adapted to the size of the internal cavity of the support frame 101. The top of the filter element 107 overlaps with the bottom of the recovery frame 201. When debris is recovered by the negative pressure airflow generated by the air pump, the debris will inevitably move with the airflow. At this time, the filter element 107 is used to separate the airflow and debris, preventing debris from entering the air pump through the conduit and causing damage to the air pump.

[0054] The specific usage process of this utility model is as follows:

[0055] Equipment installation and connection

[0056] The support frame 101 is connected and installed by fixing the connecting plate 104 to the bottom of the support table of the bench drill body 3 with bolts.

[0057] The recycling box 201 is inserted between the two support plates 103 and placed on top of the support box 101, and the installation position of the recycling box 201 is positioned by the limiting baffle 106.

[0058] Connect the exhaust pipe 102 and the air pump using conduits respectively;

[0059] Debris cleaning and recycling

[0060] When machining a workpiece using the bench drill body 3, adjust the height and angle of the bench drill body 3 support table, calibrate the machining position of the workpiece, and then start the air pump. The air pump generates negative pressure airflow that acts on the surface of the bench drill body 3 support table.

[0061] When the drill bit of the bench drill body 3 generates debris during operation, the debris will be sucked into the inside of the recovery frame 201 by the negative pressure airflow and collected.

[0062] After processing is completed, turn off all equipment, then remove the recycling box 201 to clean and recycle the accumulated debris in the recycling box 201. At the same time, remove the filter element 107 for cleaning to prevent clogging.

[0063] In summary, the chip cleaning device for bench drills of this invention, by installing a support frame 101 at the bottom of the support platform of the bench drill body 3, and setting an exhaust pipe 102 on the support frame 101 to connect with an air pump, and setting a collection frame 201 on the support frame 101, with the top of the collection frame 201 overlapping with the bottom of the support platform of the bench drill body 3, during the operation of the bench drill body 3, the airflow drawn by the air pump carries the chips into the collection frame 201 through the holes on the support platform of the bench drill body 3 for collection, avoiding the accumulation of chips on the support platform of the bench drill body 3, and preventing the accumulation of chips from interfering with the processing of the workpiece.

[0064] Meanwhile, this utility model limits the recycling frame 201 by setting support plates 103 on both sides of the top of the support frame 101, and further limits the recycling frame 201 by using support groove 105 and limiting baffle 106, so that the recycling frame 201 can be pulled out at any time during use, improving the convenience of cleaning debris.

[0065] This invention provides elastic limiting member 204 at the top of the sealing skirt 203. When the recovery frame 201 is inserted between the support frame 101 and the support table of the bench drill body 3, the elastic limiting member 204 provides elastic support to the recovery frame 201 after being compressed, thereby preventing the recovery frame 201 from moving during machining and achieving the effect of improving stability.

[0066] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0067] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
