Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, specifically to a camshaft processing equipment. Background Technology

[0002] The camshaft is a critical component of an engine, and its machining process typically involves turning and grinding, requiring the use of cutting fluid for cooling, lubrication, and chip removal. Current camshaft machining equipment often includes a cutting fluid circulation system, but this presents the following problems: 1. The purification units mostly use simple filtration or external electronic control purification devices, which are complex in structure, expensive, and prone to failure. 2. Incomplete removal of impurities such as metal chips and oil from the cutting fluid leads to rapid deterioration of the cutting fluid, affecting machining accuracy; 3. The circulation system relies on pumps and electronic sensors, which result in low reliability and inconvenient maintenance in harsh processing environments. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a camshaft processing equipment that can improve the purification function and utilization rate of cutting fluid through multi-stage circulation purification.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a camshaft machining equipment, comprising a machining unit and a cutting fluid circulation and purification system, wherein the machining unit includes a bed, a tool holder, and a machining area, characterized in that: the cutting fluid circulation and purification system is integrated inside the bed; the cutting fluid circulation and purification system includes: A collection tank, located below the machining area, is used to collect used cutting fluid; A delivery pump, the inlet of which is connected to the liquid collection tank via a pipe, is used to pump out the liquid in the liquid collection tank; A multi-stage purification tank includes an outer shell and an inner shell containing a cyclone separator, a magnetic filter, and a fine filter arranged sequentially and connected along the flow direction of the cutting fluid. The inlet of the cyclone separator is connected to the outlet of the delivery pump via a pipe. The cyclone separator separates large particulate impurities from the cutting fluid. The magnetic filter is used to adsorb ferromagnetic debris. The fine filter is used to filter out fine particles. The liquid storage tank has its inlet connected to the outlet of the fine filter via a pipe; And a nozzle, which is connected to the liquid storage tank via a return pipe, is used to spray the purified cutting fluid into the machining area.

[0005] Furthermore, the fine filter is a cartridge filter, and the cartridge of the fine filter is detachable.

[0006] Furthermore, it also includes a blockage indicator, which is connected in communication with the inlet side of the fine filter to indicate the pressure of the fine filter.

[0007] Furthermore, the blockage indicator includes a pressure probe, a pressure value indicator frame, and a U-shaped tube. The pressure value indicator frame is fixed outside the housing, and pressure values ​​are set along the height on the pressure value indicator frame. The U-shaped tube is fixed to the pressure value indicator frame, and colored liquid is placed inside the U-shaped tube. The pressure probe is a rubber diaphragm probe, which is located inside the fine filter and is connected to one end of the U-shaped tube through an air tube.

[0008] Furthermore, the bottom of the collection tank is constructed in an inclined funnel shape, which facilitates the collection of cutting fluid at the inlet of the delivery pump under the action of gravity.

[0009] Furthermore, a liquid level control device is provided inside the liquid storage tank. The liquid level control device includes a support rod, a float valve, a lever, and a cover plate. The support rod is vertically installed inside the liquid storage tank. The lever is hinged to the top of the support rod. The float valve is located at one end of the lever, and the cover plate is located at the other end of the lever. The liquid inlet of the liquid storage tank is located on the bottom plate of the liquid storage tank. When the liquid level in the liquid storage tank rises to a set height, the float valve lifts and pushes the lever to rotate until the cover plate covers the liquid inlet to close the liquid inlet.

[0010] The beneficial effects of this utility model are at least as follows: 1. Employing a multi-stage, series-connected purification process of "cyclone separation + magnetic adsorption + fine filtration," this system systematically removes various contaminants from the cutting fluid. The cyclone separator first removes most large particles, the magnetic filter efficiently removes ferromagnetic debris, and finally, the fine filter intercepts micron-sized particles. This synergistic effect ensures that the cutting fluid returning to the machining area remains highly clean, effectively preventing scratches on the workpiece surface caused by impurities, significantly improving the surface finish of the camshaft, and reducing tool wear caused by impurities, thus extending tool life.

[0011] 2. From the collection, pumping, and multi-stage purification of cutting fluid to its final reuse, the entire process is completed automatically within the equipment, forming a closed loop. Operators do not need to frequently stop the machine to change or add cutting fluid, nor do they need to transfer the cutting fluid to an external treatment facility, ensuring the continuity and stability of the machining process, thereby improving the overall production efficiency of the camshaft.

[0012] 3. The efficient purification system greatly extends the service life of the cutting fluid, reduces the amount of fresh cutting fluid to be replenished and the amount of waste fluid to be disposed of, and directly reduces production costs. Attached Figure Description

[0015] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model.

Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] Please see Figures 1 to 4 This utility model provides a camshaft machining equipment, including a machining unit and a cutting fluid circulation and purification system. The machining unit includes a bed 1, a tool post 2, and a machining area 3. The cutting fluid circulation and purification system is integrated inside the bed 1 and includes a collection tank 100, a delivery pump 200, a multi-stage purification tank 300, and nozzles 500. Specifically, the fluid collection tank 100 is located below the machining area 3 to collect used cutting fluid. In practice, the bottom of the fluid collection tank 100 can be designed as an inclined funnel shape. This design utilizes the principle of gravity flow. After the used cutting fluid, carrying chips, falls into the fluid collection tank 100, it can automatically and quickly converge at the inlet of the delivery pump 200 located at the lowest point, guided by the inclined bottom plate.

[0018] The inlet of the transfer pump 200 is connected to the liquid collection tank 100 via a pipe, and is used to pump out the liquid in the liquid collection tank 100. The transfer pump 200 can be a liquid pump commonly used in the prior art.

[0019] The multi-stage purification tank 300 includes a shell and three sequentially arranged and connected components inside the shell along the flow direction of the cutting fluid: a cyclone separator 320, a magnetic filter 330, and a fine filter 340. The inlet of the cyclone separator 320 is connected to the outlet of the transfer pump 200 via a pipe; the cyclone separator 320 is used to centrifuge and separate large particulate impurities in the cutting fluid; the magnetic filter 330 is used to adsorb ferromagnetic debris in the cutting fluid; and the fine filter 340 is used to filter out small particles in the cutting fluid.

[0020] In practical implementation, the cyclone separator 320 can be a commonly used cyclone separator 320 in the prior art, and the magnetic filter 330 can be a commonly used magnetic filter 330 or a fine filter 340 in the prior art. The fine filter 340 is a commonly used cartridge filter in the prior art.

[0021] The inlet of the reservoir 400 is connected to the outlet of the fine filter 340 via a pipe. The nozzle 500 is connected to the reservoir 400 via a return pipe and is used to spray the purified cutting fluid into the machining area 3. In a specific implementation, a resistance pump 510 can be installed between the fine filter 340 and the nozzle 500 to pump the purified fluid into the nozzle 500.

[0022] During the purification process, the cutting fluid enters the collection tank 100 through the drain hole in the machining area 3, and is then pumped into the multi-stage purification tank 300 by the transfer pump 200, where it undergoes three stages of purification.

[0023] The cyclone separator 320 performs purification: the cutting fluid enters the cylindrical cavity of the cyclone separator 320 at high speed along the tangential direction, generating a strong vortex. Under the action of centrifugal force, large particles such as denser metal particles and grinding wheel debris are thrown against the cavity wall and settle into the slag collection hopper at the bottom, achieving primary physical separation.

[0024] The magnetic filter 330 purifies the cutting fluid: after cyclone separation, the cutting fluid then flows through the magnetic filter 330. At the core of the magnetic filter 330 is a continuously rotating magnetic drum driven by a spindle. The powerful magnetic field of the drum's permanent magnets attracts all ferromagnetic debris (such as cast iron chips and steel chips) from the cutting fluid.

[0025] The cutting fluid is then purified by the fine filter 340: Finally, driven by pump pressure, the cutting fluid passes through the replaceable filter element of the fine filter 340. This filter element is composed of multiple layers of filter materials with different precision, which can effectively intercept residual tiny non-ferromagnetic particles and some oil stains, completing the fine filtration.

[0026] Finally, the purified clean cutting fluid flows into the reservoir 400 and is delivered to the nozzle 500 through the return pipe, where it is precisely sprayed back onto the contact point between the tool and the workpiece, completing a full, fully automatic cycle.

[0027] In practical implementation, the fine filter 340 can be rotated to become a removable filter cartridge, which is convenient for regular replacement.

[0028] In a preferred embodiment, a blockage indicator 600 is also included, which is connected in communication with the inlet side of the fine filter 340 and is used to indicate the pressure of the fine filter 340.

[0029] Specifically, the blockage indicator 600 includes a pressure probe 610, a pressure value indicator 620, and a U-shaped tube 630. The pressure value indicator 620 is fixed outside the housing 310, and pressure values ​​are set along the height on the pressure value indicator 620. The U-shaped tube 630 is fixed to the pressure value indicator 620, and colored liquid is placed inside the U-shaped tube 630. The pressure probe 610 is a rubber diaphragm probe, which is located inside the fine filter 340 and is connected to one end of the U-shaped tube 630 through an air tube.

[0030] When the filter element is clean and the flow is smooth, the system pressure is normal. As the usage time increases, the filter element gradually becomes clogged with impurities, causing the liquid pressure inside to gradually increase. The rubber diaphragm of the rubber diaphragm probe is pressurized and pushes the gas, which in turn moves the colored liquid inside the U-shaped tube 630. The operator can read the pressure value to decide whether to replace the filter element.

[0031] As another preferred embodiment, a mechanical float valve 720 is provided inside the liquid storage tank 400 as a liquid level control device 700.

[0032] Specifically, the liquid level control device 700 includes a support rod 710, a float valve 720, a lever 730, and a cover plate 740. The support rod 710 is vertically installed inside the liquid storage tank 400. The lever 730 is hinged to the top of the support rod 710. The float valve 720 is installed at one end of the lever 730, and the cover plate 740 is installed at the other end of the lever 730. The liquid inlet of the liquid storage tank 400 is installed on the bottom plate of the liquid storage tank 400. When the liquid level in the liquid storage tank 400 rises to the set height, the float valve 720 is lifted and pushes the lever 730 to rotate until the cover plate 740 covers the liquid inlet to close the liquid inlet.

[0033] In use, when the liquid level in the reservoir 400 drops, the float descends accordingly, opening the inlet valve via lever 730, allowing purified cutting fluid to be replenished. When the liquid level rises to the set height, the float rises, pushing lever 730 to close the inlet valve, stopping fluid replenishment. This process is fully automatic, maintaining a stable liquid level in the reservoir 400.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
