Description

Technical Field

[0001] The present invention relates to the technical field of camshaft processing equipment, in particular to a punching device for camshaft processing. Background Art

[0002] In the field of camshaft processing, drilling is a key process, and existing drilling devices have many problems that need to be solved urgently.

[0003] During the drilling process, friction between the drill bit and the camshaft generates significant heat, posing significant challenges. Existing, simple coolant spray cooling methods are ineffective. High temperatures reduce drill bit hardness, exacerbating wear, shortening tool life, and increasing tool replacement costs. Heat is also transferred to the camshaft, causing thermal deformation, impacting dimensional accuracy and surface quality, and ultimately reducing performance.

[0004] The cleaning process also suffers from flaws. After processing, the camshaft must be disassembled from the drilling equipment and transferred to specialized cleaning equipment. This process is not only tedious and time-consuming, but can also easily cause secondary contamination or damage. Furthermore, specialized cleaning equipment takes up a large space, is costly, and offers poor cleaning results, making it difficult to completely remove even small debris and oil stains.

[0005] Furthermore, existing devices have limited functionality, with dispersed drilling and cleaning processes, resulting in low equipment utilization and long processing cycles. The cleaning fluid is discharged after a single use, wasting water resources and polluting the environment. Furthermore, the system has a low degree of automation and relies heavily on manual operations, increasing labor costs and human error, while reducing processing efficiency and product quality stability. Therefore, a drilling device for camshaft machining was proposed that allows for timely cooling during the drilling process, improving drilling quality and drill bit life. Furthermore, the device allows for cleaning of the completed camshaft during machining, improving processing efficiency and reducing production costs. Summary of the Invention

[0006] The purpose of the present invention is to provide a drilling device for camshaft processing, which can timely cool down during the drilling process, improve the drilling quality and drill bit life; at the same time, the processed camshaft can be cleaned during the processing process, thereby improving processing efficiency and reducing production costs.

[0007] In order to achieve the above object, the present invention provides the following technical solutions: The technical solution provided by the present invention is: a drilling device for camshaft processing, comprising a base, a reinforcement rod fixedly provided above the base, a lifting device fixedly provided on one side of the reinforcement rod, a gas assembly fixedly provided on one side of the lifting device, a drilling assembly fixedly provided on the other side of the lifting device, a rotating device fixedly provided above the base, and a cleaning assembly provided on one side of the base; The lifting device includes a lifting slide rail fixedly installed on one side of the reinforcement rod. Above the lifting slide rail, a lifting motor is fixedly provided. The output end of the lifting motor is adaptively provided with a lifting threaded rod, and the surface of the lifting threaded rod is threadedly adapted with a lifting slide plate.

[0008] Furthermore, the gas component includes a connecting plate fixedly installed on one side of the lifting slide plate. Above the connecting plate, an air pump is fixedly provided. Below the connecting plate, an air pipe is fixedly provided. One end of the air pipe is connected to and communicates with the air pump. Below the air pipe, a pressure plate is fixedly provided, and a number of air holes are evenly opened on the side of the pressure plate.

[0009] Furthermore, the drilling component includes a drilling box fixedly installed on one side above the base and a drilling fixing plate fixedly installed on the other side of the lifting slide plate. Below the drilling fixing plate, a horizontal slide rail is fixedly provided. On one side of the horizontal slide rail, a drilling machine is fixedly provided. On one side of the drilling machine, a snap ring is fixedly provided; Below the drilling box, a filter box is opened. On the surface of the filter box, a number of filter plates are provided. On one side of the filter box, a filter pipe is opened.

[0010] Furthermore, the rotating device includes a rotating motor fixedly installed in the base. The output end of the rotating motor is fixedly provided with a rotating shaft. On both sides of the rotating shaft, rotating plates are symmetrically provided. At one end of each rotating plate, a snap-in ring is fixedly provided. On the side of the snap-in ring, a number of air permeable grooves are opened. Inside the snap-in ring, a camshaft is snap-fitted and placed; On the inner wall of the snap-in ring, a number of telescopic damping rods are evenly provided. Below the telescopic damping rods, a snap-in plate is fixedly provided, and the size of the snap-in plate is the same as that of the bottom of the snap-in ring.

[0011] Furthermore, the cleaning component includes a cleaning box fixedly installed on one side of the inner wall of the base. Inside the cleaning box, a number of cleaning filter meshes are evenly provided. Below the cleaning box, a circulation pipe is fixedly provided. Above the cleaning box, a cleaning groove is opened.

[0012] Furthermore, the size of the cleaning groove is the same as that of the snap-in plate.

[0013] The beneficial effects of this technical solution are: (1) During the drilling process, the air pump, the circulation pipe, and the cleaning box together constitute an efficient cooling system. The air pressure generated by the air pump transports the cleaning liquid in the cleaning box to the drilling site through the circulation pipe, cooling the camshaft and the drilling machine in a timely manner. A large amount of heat generated during the drilling process will cause the temperature of the drill bit and the camshaft to rise sharply. Excessive temperature will accelerate the wear of the drill bit, reduce the service life of the drill bit, and may also affect the material properties of the camshaft. Through the cooling system of the present invention, the temperature at the drilling site can be effectively reduced, the adverse effects of heat on the drill bit and the camshaft can be reduced, the service life of the drill bit can be extended, and the maintenance cost and replacement frequency of the equipment can be reduced.

[0014] (2) One of the greatest advantages of the present invention is that it can clean the machined camshaft while machining the camshaft. During the drilling process, the gas assembly descends to push the clamping plate to immerse the machined camshaft into the cleaning tank. The bubbles generated by the air pump drive the cleaning liquid to fluctuate to clean the camshaft. This synchronous machining and cleaning method avoids the step of transferring the camshaft to a dedicated cleaning device for cleaning in the traditional machining process, saving a large amount of time and labor costs and greatly improving the machining efficiency. The rotating device can achieve a 180-degree rotation of the clamping ring, enabling the camshaft to be machined and the machined camshaft to quickly switch positions, realizing continuous cyclic machining. The operator only needs to place the camshaft to be machined on one side, and the equipment can automatically complete a series of operations such as drilling, cleaning, and position switching, forming an efficient machining cycle. This continuous cyclic machining mode reduces the idle time of the equipment, improves the utilization rate of the equipment, and further enhances the overall machining efficiency.

[0015] (3) The cleaning tank, the filtering tank, and the filter pipe jointly realize the recycling of the cleaning liquid. After the cleaning liquid cleans the camshaft and cools the drilling machine, it flows into the filtering tank carrying impurities. The filter plate in the filtering tank can effectively filter out impurities such as debris in the cleaning liquid, purifying the cleaning liquid. The purified cleaning liquid returns to the cleaning tank through the filter pipe and continues to participate in the cleaning and cooling process. This recycling method greatly reduces the consumption of the cleaning liquid, reduces the production cost, and at the same time meets the environmental protection requirements and reduces the pollution to the environment.

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Please refer to Figure 1-6 , a technical solution provided by the present invention: a drilling device for camshaft processing, including a base 1, a reinforcing rod 2 is fixedly arranged above the base 1 by welding. This welding fixing method can ensure the stability of the connection between the reinforcing rod 2 and the base 1, providing a stable support for the installation of subsequent other devices. One side of the reinforcing rod 2 is fixedly provided with a lifting device 3 by bolts. The bolt connection is convenient for installation and disassembly, facilitating the maintenance and replacement of the lifting device 3. One side of the lifting device 3 is fixedly provided with a gas assembly by welding 4 to ensure that the gas assembly 4 can be lifted and lowered stably with the lifting device 3; on the other side of the lifting device 3, a drilling assembly 5 is also fixedly provided by welding. A rotating device 6 is fixedly arranged above the base 1 by bolts, and a cleaning assembly 7 is fixedly arranged on one side of the base 1 by bolts; The lifting device 3 includes a lifting slide rail 301 fixedly installed on one side of the reinforcing rod 2 by bolts. A lifting motor 302 is fixedly arranged above the lifting slide rail 301 by bolts. The output end of the lifting motor 302 is key-connected with a lifting threaded rod 303 through a coupling. The key connection can ensure the effective transmission of the power of the lifting motor 302 to the lifting threaded rod 303, making it rotate synchronously. A lifting slide plate 304 is thread-fitted on the surface of the lifting threaded rod 303. When the lifting threaded rod 303 rotates, the lifting slide plate 304 will move up and down along the lifting slide rail 301, thereby driving the gas assembly 4 and the drilling assembly 5 to lift and lower; The gas assembly 4 includes a connecting plate 401 fixedly installed on one side of the lifting slide plate 304 by welding. Above the connecting plate 401, an air pump 402 is fixedly installed by bolts, which facilitates the maintenance and repair of the air pump 402. Below the connecting plate 401, an air pipe 403 is fixedly installed by welding. One end of the air pipe 403 is connected and communicated with the air pump 402 through a sealing joint to ensure the tightness of gas transmission. Below the air pipe 403, a pressure plate 404 is fixedly installed by welding. A number of air holes 405 are evenly opened on the side of the pressure plate 404. The air pump 402 operates to generate gas, which is transported to the pressure plate 404 through the air pipe 403, and the gas is discharged from the air holes 405, which can generate bubbles in the water source in the cleaning tank 701 and generate air pressure during the cleaning process; The drilling assembly 5 includes a drilling box 501 fixedly installed on one side above the base 1 by bolts and a drilling fixing plate 502 fixedly installed on the other side of the lifting slide plate 304 by welding. Below the drilling fixing plate 502, a horizontal slide rail 503 is fixedly installed by bolts. On one side of the horizontal slide rail 503, a drilling machine 504 is arranged in a manner of cooperating with a slider and the slide rail. This cooperation method enables the drilling machine 504 to move smoothly on the horizontal slide rail 503, facilitating the adjustment of the drilling position. On one side of the drilling machine 504, a clamping ring 505 is fixedly installed by welding. Below the drilling box 501, a filter box 506 is opened. A number of filter plates 507 are fixedly installed on the surface of the filter box 506 through card slots. The card slot fixing method facilitates the installation and replacement of the filter plates 507. On one side of the filter box 506, a filter pipe 508 is opened. The drilling machine 504 can move on the horizontal slide rail 503 to drill the camshaft 605. The cooled water source is collected through the filter box 506, filtered by the filter plates 507, and then recycled through the filter pipe 508; The rotating device 6 includes a rotating motor fixedly installed in the base 1 by bolts. The output end of the rotating motor is fixedly connected to a rotating shaft 601 through a key connection by a coupling, ensuring the effective transmission of the power of the rotating motor to the rotating shaft 601. On the side of the rotating shaft 601, rotating plates 602 are symmetrically arranged by welding. One end of each rotating plate 602 is fixedly installed with a clamping ring 603 by welding. A number of air permeable grooves 604 are opened on the side of the clamping ring 603. A camshaft 605 is clamped and placed in the clamping ring 603. A number of telescopic damping rods 606 are evenly fixedly installed on the inner wall of the clamping ring 603 by bolts. Below the telescopic damping rods 606, a clamping plate 607 is fixedly installed by bolts. The clamping plate 607 has the same size as the bottom of the clamping ring 603. When the rotating motor operates, it drives the rotating shaft 601 and the rotating plates 602 to rotate, thereby rotating the clamping ring 603 and realizing the position switching of the camshaft 605; The cleaning component 7 includes a cleaning tank 701 fixedly installed on one side of the inner wall of the base 1 by bolts. A number of cleaning filters 702 are evenly arranged in the cleaning tank 701 through card slots, which facilitates the replacement and cleaning of the cleaning filters 702. A circulation pipe 703 is fixedly installed below the cleaning tank 701 by welding. A cleaning groove 704 is opened above the cleaning tank 701, and the size of the cleaning groove 704 is the same as that of the clamping plate 607. The cleaning tank 701 is filled with a cleaning liquid, and the camshaft 605 is cleaned by the air pressure and bubbles generated by the air pump 402. The cleaned water source is recycled through the circulation pipe 703; The specific implementation process is as follows: Before using the drilling device for machining the camshaft 605, first inject an appropriate amount of cleaning liquid into the cleaning tank 701, and at the same time ensure that all components such as the lifting device 3, the gas component 4, the drilling component 5, and the rotating device 6 are correctly installed and debugged, and the control device can normally control the operation of each motor and the air pump 402; First processing flow: Place the camshaft 605 to be processed into the clamping ring 603, so as to firmly fix the camshaft 605 in the clamping ring 603, prevent it from rotating or shaking during the subsequent drilling process, and ensure the accuracy of the drilling position; The operator starts the rotating motor through the control device. The rotating motor starts to operate and drives the rotating shaft 601 to rotate through the key connection of the coupling. The rotation of the rotating shaft 601 causes the rotating plate 602 fixedly welded to it to rotate synchronously, and then drives the clamping ring 603 welded to the end of the rotating plate 602 to rotate 180 degrees. In this way, the clamping ring 603 carrying the camshaft 605 is moved into the drilling box 501 and is directly below the drilling component 5. At the same time, another empty clamping ring 603 rotates to a position where a new camshaft 605 can be placed, and the operator can place a new camshaft 605 to be processed here; The operator starts the lifting motor 302 again through the control device. The lifting motor 302 operates, and its output end drives the lifting screw rod 303 to rotate through the key connection of the coupling. Since the lifting screw rod 303 is thread-fitted with the lifting slide plate 304, the rotation of the lifting screw rod 303 will cause the lifting slide plate 304 to move downward along the lifting slide rail 301. Because the connecting plate 401 of the gas component 4 and the drilling fixing plate 502 of the drilling component 5 are respectively welded on both sides of the lifting slide plate 304, the gas component 4 and the drilling component 5 will descend together with the lifting slide plate 304; During the descent of the drilling component 5, the drilling machine 504 can be moved and adjusted on the transverse slide rail 503 according to the actual drilling position requirements. When the drilling machine 504 moves to a suitable position, start the drilling machine 504 and start the drilling operation on the camshaft 605 in the clamping ring 603 below; When the gas assembly 4 descends, the air pressure plate 404 will contact the clamping plate 607 within the clamping ring 603 above the cleaning assembly 7 and push it into the cleaning tank 701; During the drilling process, the air pump 402 is started. The gas generated by the air pump 402 is transported through the air pipe 403 to the air pressure plate 404 and discharged from the air holes 405 on the side of the air pressure plate 404. The gas enters the cleaning liquid in the cleaning tank 701 to generate a large number of bubbles. On the one hand, these bubbles drive the cleaning liquid to fluctuate, creating conditions for the subsequent cleaning of the camshaft 605. On the other hand, since the cleaning tank 701 is relatively sealed, the continuous injection of gas increases the air pressure inside the tank, squeezing out the cleaning liquid through the circulation pipe 703. The other end of the circulation pipe 703 is fixedly connected to the clamping ring 505. The squeezed cleaning liquid will flow towards the camshaft 605 and the drilling machine 504 during the drilling process to cool them, reducing the impact of the heat generated by drilling on the drilling quality and the drill bit life; When the drilling operation is completed, the lifting motor 302 is controlled by the control device to reverse, causing the lifting device 3 to rise, driving the gas assembly 4 and the drilling assembly 5 back to the initial position. Then, the rotation motor is started again to rotate the rotating device 6 by 180 degrees, rotating the processed camshaft 605 above the cleaning assembly 7 for subsequent cleaning, and at the same time moving the newly placed camshaft 605 to be processed to the drilling position; For the second and subsequent processing processes, the basic processes of the second and subsequent processing are similar to the first processing, but there are more coherent operations in terms of the cleaning and cooling cycles; The rotating device 6 moves the clamping ring 603 where the camshaft 605 that has been preliminarily cleaned and is above the cleaning assembly 7 to inside the drilling box 501, below the drilling assembly 5, and rotates the camshaft 605 that was processed last time above the cleaning assembly 7; The lifting motor 302 is started, and the lifting device 3 descends, driving the drilling assembly 5 to drill the new camshaft 605 to be processed. At the same time, the air pressure plate 404 of the gas assembly 4 descends. The air pressure plate 404 is movably adapted to the inner wall of the clamping ring 603. It will push the camshaft 605 above the cleaning assembly 7, causing the camshaft 605 to push the clamping plate 607 down, completely immersing the camshaft 605 in the cleaning liquid in the cleaning tank 701; The air pump 402 continues to operate, continuously injecting gas into the cleaning tank 701 to generate bubbles. The bubbles drive the cleaning liquid to fluctuate violently, comprehensively cleaning the camshaft 605 immersed in it to remove impurities such as debris and oil stains on the surface. At the same time, the increased air pressure in the cleaning tank 701 squeezes out the excess cleaning liquid through the circulation pipe 703 and transports it to the drilling machine 504 for cooling. The cooled cleaning liquid carries debris and other impurities generated by drilling and flows into the filter tank 506 below the drilling box 501; The filter plate 507 in the filter box 506 filters the incoming cleaning liquid to remove impurities such as debris. When the air pump 402 does not extend the air pressure plate 404 into the cleaning box 701, the filtered clean cleaning liquid is discharged back into the cleaning box 701 through the filter pipe 508, realizing the recycling of the cleaning liquid, saving water resources and reducing production costs.

[0020] Working principle: When used for the first time, the camshaft 605 is placed into the clamping ring 603, the rotation motor is started to rotate the rotating plate 602 by 180 degrees to move the camshaft 605 to the drilling position. The lifting motor 302 is started to lower the drilling assembly 5, and at the same time, the drill 504 is started to drill the camshaft 605. The air pump 402 is started to generate air pressure and bubbles to circulate the water source in the cleaning box 701 to cool the camshaft 605 and the drill 504 during the drilling process. After the drilling is completed, the lifting device 3 rises and the rotating device 6 rotates by 180 degrees to move the processed camshaft 605 to the cleaning position. During the second and subsequent processing, the above steps are repeated. The air pressure plate 404 descends to push the camshaft 605 into the cleaning box 701 for cleaning, and at the same time, the cleaning liquid is recycled to cool the drill 504.
