Description

Technical Field

[0001] The utility model relates to a self-lubricating drill press for the production of steel shovels, in particular to a self-lubricating drill press for the production of steel shovels applied to the field of drill press equipment. Background Art

[0002] A drill press mainly refers to a machine tool for machining holes in workpieces with a drill bit. Usually, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The drill press has a simple structure and relatively low machining accuracy. It can drill through holes and blind holes. By replacing special tools, it can perform operations such as reaming, countersinking, boring, or tapping. During the machining process, the workpiece remains stationary while the tool moves. The center of the tool is aligned with the center of the hole, and the tool rotates (main movement). The characteristic of the drill press is that the workpiece is fixed and the tool makes a rotational movement.

[0003] The specification of Chinese Patent CN220943241U discloses a drill press device, belonging to the technical field of drill presses. It includes a workbench, and a guide rail is fixedly connected to the workbench. In the utility model, the protective box can block the splashing of debris and protect the staff from being injured. The installation operation of the fixture is simplified by the engagement of the clamping block and the clamping groove, so that the working surface of the clamping plate can be quickly replaced to complete the drilling work of different workpieces.

[0004] The specification of Chinese Patent CN220278942U discloses a drill press, which relates to the technical field of machining. It includes a bottom plate. In the utility model, by fixedly connecting a mounting plate to the top end of the electric telescopic rod, the situation that the drilling position deviates due to the manual adjustment of the spherical workpiece by the worker is avoided.

[0005] After placing the original steel shovel piece on the drill table and fixing it with the fixture table, the drill bit can perform drilling operations on the original steel shovel piece. After the drill bit has been drilling for a period of time, when a large amount of debris adheres to the surface of the drill bit, this will not only reduce the service life of the drill bit, but also may increase the surface roughness of the workpiece and affect the machining quality. In the prior art, manual intervention is required to disassemble, clean the chips and apply oil and other maintenance operations to the drill bit, which is not conducive to ensuring the relevant processing efficiency. Therefore, it is necessary to design a self-lubricating drill press for the production of steel shovels with a drill bit maintenance function to solve the above problems. Summary of the Utility Model

[0006] Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is that after the drill bit has been drilling for a period of time, when a large amount of debris adheres to the surface of the drill bit, this will not only reduce the service life of the drill bit, but also may increase the surface roughness of the workpiece and affect the machining quality. In the prior art, manual intervention is required to disassemble, clean the chips and apply oil and other maintenance operations to the drill bit, which is not conducive to ensuring the relevant processing efficiency.

[0007] To solve the above problems, the present utility model provides a self-lubricating drill press for steel shovel production, including a vertical rod. The upper end of the vertical rod is fixedly connected with a driving housing. The output end of the driving housing is equipped with a bearing rod. The lower end of the bearing rod is equipped with a drill bit. The outer end of the vertical rod is equipped with a drill table. The middle of the drill table is provided with an opening. The left and right inner walls of the opening are symmetrically provided with side slots. The inner side wall of the side slot is fixedly connected with an electric push rod. The output end of the electric push rod is fixedly connected with a semi-circular oil-soaked sponge ring, which is in contact with the drill bit. The left and right inner walls of the opening are symmetrically equipped with self-returning rotating shaft parts. The outer end of the self-returning rotating shaft part is provided with an abutting block. The left and right inner walls of the opening are symmetrically equipped with electric push rod contact switches.

[0008] In the above self-lubricating drill press for steel shovel production, this solution uses the opening in the drill table to attach the oil liquid to the outer wall of the drill bit to achieve a maintenance effect. At the same time, the driving point of the electric push rod can be realized by setting an electric push rod contact switch in the opening. The overall process path is reasonable. At the same time, the semi-circular scraping ring contacts the outer wall of the drill bit to scrape off the attached residual debris, eliminating the need for manual intervention in disassembling and cleaning the drill bit and applying oil for maintenance operations, which is conducive to ensuring the processing efficiency of the original steel shovel pieces.

[0009] As a further improvement of the present application, the left and right sides of the lower end of the drill table are symmetrically and fixedly connected with side crossbars, and a semi-circular scraping ring is installed at one end of the side crossbar close to the semi-circular oil-soaked sponge ring.

[0010] As a further improvement of the present application, the semi-circular scraping ring cooperates with the drill bit, and the lower end of the vertical rod is fixedly connected with a base.

[0011] As a further improvement of the present application, the drill bit corresponds to the opening, and a fixture table is arranged at the upper end of the drill table.

[0012] As another improvement of the present application, the two electric push rod contact switches cooperate with the corresponding abutting blocks, and the abutting blocks cooperate with the bearing rod.

[0013] As a supplementary improvement of the present application, a transparent bottom frame is clamped at the lower end of the drill table, and the transparent bottom frame is located outside the semi-circular scraping ring.

[0014] As a supplementary improvement of the present application, a brush ring is fixedly connected to the inner side wall of the semi-circular scraping ring, and the brush ring is in contact with the outer side wall of the drill bit.

[0015] In summary, in the present solution, two side slots are provided in the opening in the drill floor. The electric push rods in the two side slots can drive the oil-soaked sponge semi-circular ring close to the returning drill bit, attach the oil liquid to the outer wall of the drill bit, and achieve the maintenance effect. At the same time, the driving point of the electric push rod can be realized by setting an electric push rod contact switch in the opening. The overall process path is reasonable. When the drill bit presses down, the semi-circular scraping ring contacts the outer wall of the drill bit to scrape off the attached residual debris, making the coating and maintenance effect of the oil liquid better. There is no need for manual intervention in the maintenance operations such as disassembling, clearing chips, and applying oil to the drill bit, which is conducive to ensuring the processing efficiency of the original steel shovel pieces.

[0025] The following will describe in detail the two embodiments of the present application with reference to the drawings.

[0026] The first embodiment:

[0027] Figures 1-6There is shown a self-lubricating drill press for shovel production, including a vertical rod 1. The upper end of the vertical rod 1 is fixedly connected to a driving housing 2. The output end of the driving housing 2 is equipped with a bearing rod 7. The lower end of the bearing rod 7 is equipped with a drill bit 3. The outer end of the vertical rod 1 is equipped with a drill table 4. A through hole 8 is formed in the middle of the drill table 4. Side slots 9 are symmetrically formed in the left and right inner walls of the through hole 8. The inner side wall of the side slot 9 is fixedly connected to an electric push rod 18. The output end of the electric push rod 18 is fixedly connected to an oil-soaked sponge semi-circle 10. The oil-soaked sponge semi-circle 10 is in contact with the drill bit 3. Self-returning rotating shaft members 11 are symmetrically installed on the left and right inner walls of the through hole 8. A contact block 12 is arranged at the outer end of the self-returning rotating shaft member 11. Electric push rod contact switches 13 are symmetrically installed on the left and right inner walls of the through hole 8.

[0028] Figures 1-6 It is shown that symmetrically fixed connection side cross bars 16 are arranged on the left and right sides at the lower end of the drill table 4. A semi-circular scraping ring 15 is installed at one end of the side cross bar 16 close to the semi-circular scraping ring 15. The semi-circular scraping ring 15 cooperates with the drill bit 3. The lower end of the vertical rod 1 is fixedly connected to a base 6. The drill bit 3 corresponds to the through hole 8. A fixture table 5 is arranged at the upper end of the drill table 4. The two electric push rod contact switches 13 cooperate with the corresponding contact blocks 12. The contact block 12 cooperates with the bearing rod 7.

[0029] Figures 1-6It is shown that after the original steel shovel piece is placed on the drilling table 4 and fixed by the fixture table 5 in this solution, the drill bit 3 can perform drilling operations on the original steel shovel piece. After the drill bit 3 has been drilling for a period of time, when a large amount of debris adheres to the surface of the drill bit 3, this will not only reduce the lifespan of the drill bit, but may also cause an increase in the surface roughness of the workpiece, affecting the processing quality. In the prior art, manual intervention is required to disassemble, clean the chips, and apply oil to the drill bit 3 for maintenance operations, which is not conducive to ensuring the relevant processing efficiency. Therefore, it is necessary to design a self-lubricating drill press for steel shovel production with a drill bit 3 maintenance function to solve the above problems. Therefore, two side slots 9 are provided in the opening 8 in the drilling table 4. The electric push rods 18 in the two side slots 9 can drive the oil-soaked sponge semi-circular ring 10 to approach the returning drill bit 3, attaching the oil fluid to the outer wall of the drill bit 3, achieving a maintenance effect. At the same time, the driving point of the electric push rod 18 can be realized by setting an electric push rod contact switch 13 in the opening 8. The electric push rod contact switch 13 is driven by an externally connected control terminal, which is prior art and will not be elaborated in this solution. The starting point of the electric push rod contact switch 13 is when the drill bit 3 completely penetrates the opening 8. The slightly wider load-bearing rod 7 squeezes the abutting block 12 outside the self-returning rotating shaft member 11 to make it rotate downward and contact the electric push rod contact switch 13. At this time, the electric push rod 18 is synchronously pushed out. After the oil-soaked sponge semi-circular ring 10 is pushed out, it just contacts the outer wall of the returning drill bit 3. The overall process path is reasonable. At the same time, before the oil-soaked sponge semi-circular ring 10 contacts the drill bit 3, when the drill bit 3 presses down, the inner side wall of the semi-circular scraping ring 15 can contact the outer side wall of the drill bit 3. The contact between the semi-circular scraping ring 15 and the outer wall of the drill bit 3 can scrape off the attached and remaining debris, making the oil application and maintenance effect better. There is no need for manual intervention to disassemble, clean the chips, and apply oil to the drill bit 3 for maintenance operations, which is conducive to ensuring the processing efficiency of the original steel shovel piece.

[0030] The second implementation method:

[0031] Figure 3 , Figure 7 It is shown that a transparent bottom frame 14 is clamped at the lower end of the drilling table 4. The transparent bottom frame 14 is located outside the semi-circular scraping ring 15. A brush ring 17 is fixedly connected to the inner side wall of the semi-circular scraping ring 15, and the brush ring 17 contacts the outer side wall of the drill bit 3. A self-lubricating drill press for steel shovel production. At the same time, when the semi-circular scraping ring 15 scrapes off the debris outside the drill bit 3, a brush ring 17 can be added at the inner ring position of the semi-circular scraping ring 15. The brush ring 17 can improve the contact efficiency with the threaded outer wall surface of the drill bit 3, making the scraping efficiency of debris better. At the same time, a transparent bottom frame 14 is provided under the drilling table 4. The transparent bottom frame 14 can collect the scraped debris, and it is not easy to generate the risk of material splashing, which is conducive to ensuring the standardization of the operation platform.

[0032] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
