Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically a drilling machine frame with a function to prevent iron filings from flying. Background Technology

[0002] Drilling machines are widely used in the field of metal processing, but during operation, the high-speed friction between the drill bit and the metal workpiece generates a large amount of high-temperature iron filings.

[0003] The existing patent document CN219211664U discloses a positioning plate machining drilling machine. This utility model adjusts the relative position of the workpiece and the drilling mechanism through an adjustment mechanism. The drive mechanism drives the drilling mechanism to move through the feed box, thereby achieving the effect of drilling the workpiece. When the feed box moves closer to the workpiece, the transmission mechanism drives the protective box to move downward. The protective box can shield the workpiece and the three-jaw chuck, which helps to reduce the probability of waste chips splashing when the drilling mechanism processes the workpiece, and facilitates the protection of the operator. The upper end of the recovery box of this utility model is fixed with a filter plate, and an inclined plate is fixed inside the recovery box. The recovery box is connected to a drain pipe. The filter plate helps to collect waste chips, and the coolant will flow into the recovery box through the filter plate, which facilitates the effect of coolant recovery.

[0004] However, existing drill press frames designed to prevent metal shavings from splashing are not conducive to building efficient and easy-to-maintain metal shavings handling structures. Although existing drill press frames collect waste chips through filter plates and use inclined plates for auxiliary flow guidance, the filter plates are mostly fixedly installed and lack a design similar to the sliding fit between the plug plate and the base groove. Subsequent disassembly, cleaning, or replacement requires disassembling the relevant components of the recycling box, which is cumbersome. Furthermore, there is no protective side door corresponding to the metal shavings accumulation area of ​​the filter plate. Daily cleaning of waste chips requires opening the entire structure of the recycling box (such as the box door), making it impossible to directly target the accumulation area for quick cleaning. This can easily lead to waste chips scattering or interfering with other internal components during the cleaning process. At the same time, conventional flat plate filter plates cannot expand the contact area of ​​metal chips and guide the flow of waste chips like inverted V-shaped filter plates, which can easily lead to local accumulation and blockage of waste chips on the filter plate. The effect of balancing metal shavings collection efficiency and maintenance convenience is poor. Utility Model Content

[0005] Technical problems to be solved The purpose of this invention is to provide a drill press frame with a feature to prevent metal shavings from splashing, thereby solving the problem mentioned in the background art that existing drill press frames with features to prevent metal shavings from splashing are not convenient for constructing efficient and easy-to-maintain metal shavings handling structures.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a drilling machine frame with anti-splattering iron filings, comprising a base, with support columns vertically welded to the four corners of the upper surface of the base, the tops of the four support columns jointly supporting a horizontally arranged worktable, the upper surface of the worktable covered with a transparent protective cover, an inverted V-shaped filter plate horizontally arranged inside the base, with plug-in plates symmetrically extending from both sides of the inverted V-shaped filter plate, and grooves adapted to the plug-in plates corresponding to the inner sidewalls of the base, the plug-in plates slidingly engaging with the grooves, and protective side doors hinged to both sides of the base at positions corresponding to the lower ends of the inverted V-shaped filter plates.

[0007] As a further improvement to the above solution, the side of the transparent protective cover is hinged with an operating door, and a main shaft clearance hole is provided in the middle of the top of the transparent protective cover.

[0008] As a further improvement to the above solution, a machining hole is provided in the middle of the top of the worktable, and the machining hole is coaxially arranged with the spindle clearance hole.

[0009] As a further improvement to the above solution, rectangular positioning grooves are radially distributed around the machining holes on the upper surface of the worktable, and external threaded positioning pins are movably arranged inside the rectangular positioning grooves.

[0010] As a further improvement to the above solution, the outer surface of the external threaded locating pin is threadedly fitted with an internal threaded locating block, which is located above the worktable.

[0011] As a further improvement to the above solution, a material guiding channel is connected between the workbench and the base, and a sealed door is hinged to one side of the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This drilling machine frame with anti-splashing features constructs an efficient scrap handling structure through an inverted V-shaped filter plate, plug-in plates, and protective side doors. The inverted V-shaped filter plate is horizontally positioned inside the base. The V-shaped structure diverts and receives scrap falling from the guide channel, expanding the contact area and guiding the scrap to slide to both sides, preventing accumulation and blockage. The plug-in plates on both sides of the filter plate slide into the grooves inside the base, facilitating filter plate disassembly, cleaning, or replacement without disassembling the entire base. The protective side doors on both sides of the base, corresponding to the bottom of the filter plate, can be directly aimed at the scrap accumulation area. Daily cleaning does not require opening the base's sealed door; simply opening the protective side doors allows for quick scrap removal, balancing collection efficiency and maintenance convenience, and ensuring stable frame operation. 2. This drilling machine frame with a chip-proof design features a transparent protective cover over the worktable, with hinged operating doors on the sides and a spindle clearance hole at the top, creating a comprehensive chip protection structure. The transparent cover blocks chips that fly in all directions during machining, preventing burns to operators or environmental pollution. The side operating doors facilitate workpiece clamping and loading, and reduce chip leakage gaps when closed. The top spindle clearance hole is coaxial with the machining holes on the worktable, ensuring that the drilling machine spindle can smoothly pass through the protective cover for operation. This does not affect the machining process and achieves complete protection from the top and sides, significantly reducing the safety hazards of chip splashing. 3. This drilling machine frame with anti-chip splash feature uses radial rectangular positioning grooves around the machining hole on the worktable, along with external threaded positioning pins and internal threaded positioning blocks, to achieve flexible workpiece positioning. The external threaded positioning pins can slide and adjust their position along the rectangular positioning grooves to accommodate workpieces of different sizes and shapes. After adjustment, tightening the internal threaded positioning block above the worktable will fix the positioning pins, quickly completing the workpiece limiting and preventing workpiece displacement during machining from expanding the chip splash range or affecting machining accuracy. Compared with traditional fixed fixtures, the adaptability and ease of operation are significantly improved. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 4This utility model provides a technical solution: a drill press frame with anti-scraping iron filings frame, including a base 1, with support columns 2 vertically welded to the four corners of the upper surface of the base 1, the tops of the four support columns 2 jointly supporting a horizontally set worktable 3, the upper surface of the worktable 3 covered with a transparent protective cover 4, an inverted V-shaped filter plate 5 horizontally set inside the base 1, and plug-in plates 6 symmetrically extending from both sides of the inverted V-shaped filter plate 5, and grooves adapted to the plug-in plates 6 correspondingly opened on the inner side wall of the base 1, the plug-in plates 6 slidingly engaging with the grooves, and protective side doors 7 hinged to the lower ends of both sides of the base 1 on both side walls corresponding to the lower ends of the inverted V-shaped filter plate 5.

[0017] The inverted V-shaped filter plate 5 inside the base 1 catches the falling iron filings. Its V-shaped structure expands the contact area and guides the iron filings to slide down the inclined surfaces on both sides, preventing them from accumulating and clogging in the middle of the filter plate. This achieves the diversion and collection of iron filings. When cleaning iron filings, simply open the protective side doors 7 on both sides of the base 1, which correspond to the lower end of the inverted V-shaped filter plate 5, to quickly clean the iron filings accumulated on the filter plate without disassembling other structures. If a deep cleaning or replacement of the inverted V-shaped filter plate 5 is required, the plug plates 6 on both sides of the filter plate (which slide apart from the inner groove of the base 1) can be pulled out to remove the filter plate for maintenance.

[0018] The transparent protective cover 4 has an operating door 8 hinged to its side. A spindle clearance hole 9 is provided in the middle of the top of the transparent protective cover 4. A machining hole 10 is provided in the middle of the top of the worktable 3. The machining hole 10 is coaxial with the spindle clearance hole 9. Rectangular positioning grooves 11 are radially distributed around the machining hole 10 on the upper surface of the worktable 3. An external threaded positioning pin 12 is movably installed inside the rectangular positioning groove 11. An internal threaded positioning block 13 is threadedly sleeved on the outer surface of the external threaded positioning pin 12. The internal threaded positioning block 13 is located above the worktable 3. A material guide channel 14 connects the worktable 3 and the base 1. A sealing door 15 is hinged to one side of the base 1.

[0019] Open the operating door 8 on the side of the transparent protective cover 4, place the workpiece to be processed on the worktable 3, and adjust the position of the external thread positioning pin 12 by sliding along the rectangular positioning grooves 11 that are radially distributed around the processing hole 10, according to the size of the workpiece and the processing position requirements, so that the positioning pin fits against the edge of the workpiece. Then tighten the internal thread positioning block 13 above the worktable 3, and fix the external thread positioning pin 12 by thread locking, thus completing the stable positioning of the workpiece and preventing the workpiece from shifting during processing and causing the range of metal chips to expand. After confirming that the workpiece is positioned correctly, close the operating door 8 to form a closed protective space. The drill spindle is vertical through the spindle clearance hole 9 at the top of the transparent protective cover 4. The spindle moves downwards, passes through the protective cover, and aligns with the machining hole 10 on the worktable 3 to make contact with the workpiece for drilling. During the machining process, the transparent protective cover 4 prevents iron filings from splashing in all directions, avoiding burns to operators or environmental pollution. The coaxial design of the spindle clearance hole 9 and the machining hole 10 ensures normal spindle operation without compromising the integrity of the protection. The iron filings generated during machining fall through the machining hole 10 into the guide channel 14 between the worktable 3 and the base 1, and are then directionally transported to the interior of the base 1 through the guide channel 14. By opening the sealing door 15 on the side of the base 1, residual iron filings inside the base 1 or the guide channel 14 can be inspected and repaired, ensuring the long-term stable operation of the machine frame.

[0020] Working principle: Open the operating door 8 on the side of the transparent protective cover 4, place the workpiece to be processed on the worktable 3, and adjust the position of the external thread positioning pin 12 along the rectangular positioning grooves 11 radially distributed around the processing hole 10 according to the workpiece size and processing position requirements. Make the positioning pin fit against the edge of the workpiece. Then tighten the internal thread positioning block 13 above the worktable 3 to fix the external thread positioning pin 12 through thread locking, thus completing the stable positioning of the workpiece and preventing the workpiece from shifting during processing and causing the iron filings to spread. After confirming that the workpiece is correctly positioned, close the operating door 8 to form a closed protective space. The drill spindle moves vertically downward through the spindle clearance hole 9 at the top of the transparent protective cover 4, passes through the inside of the protective cover, and aligns with the processing hole 10 on the worktable 3 to make contact with the workpiece for drilling. During the processing, the transparent protective cover 4 prevents iron filings from splashing in all directions, avoiding burns to operators or environmental pollution. The spindle clearance hole 9 and the processing hole 10 are coaxially designed. To ensure the spindle operates normally without compromising its protective integrity, the iron filings generated during processing fall through the machining holes 10 into the guide channel 14 between the worktable 3 and the base 1. The guide channel 14 then directs the iron filings into the base 1, where the inverted V-shaped filter plate 5 receives them. Its V-shaped structure expands the contact area and guides the iron filings to slide down the inclined surfaces on both sides, preventing them from accumulating and clogging in the middle of the filter plate. This achieves the diversion and collection of iron filings. For routine cleaning, simply open the protective side doors 7 on both sides of the base 1, corresponding to the lower end of the inverted V-shaped filter plate 5, to quickly clean the accumulated iron filings on the filter plate without disassembling other structures. If deep cleaning or replacement of the inverted V-shaped filter plate 5 is required, the plug plates 6 on both sides of the filter plate (slidably separated from the inner groove of the base 1) can be pulled out, and the filter plate removed for maintenance. Opening the sealing door 15 on the side of the base 1 allows for inspection of residual iron filings inside the base 1 or the guide channel 14, ensuring long-term stable operation of the machine frame.

[0021] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
