Description

Technical Field

[0001] This invention belongs to the technical field of spindle machining, and more specifically, it relates to a special grinding machine for spindle machining based on a control component. Background Technology

[0002] Spindle-type workpieces are widely used in machine tools, automobiles, motors, and precision transmission equipment. Their machining accuracy directly affects the operational stability and service life of the equipment. During spindle machining, rough grinding and fine grinding of the spindle's outer diameter, stepped surfaces, or mating parts are usually required using a grinding machine to improve the spindle's dimensional accuracy, roundness accuracy, and surface quality.

[0003] The existing technology for spindle machining still has the following drawbacks: First, during spindle grinding, the grinding wheel typically rotates at a high speed, easily forming a high-speed airflow layer around its outer circumference. This causes the sprayed coolant to be blocked or scattered by the airflow, making it difficult for it to effectively enter the actual grinding contact area between the grinding wheel and the workpiece. Simultaneously, existing cooling nozzles mostly employ a fixed spray method. When the spindle has dimensional errors, installation deviations, rotational runout, or thermal deformation, the spray position is prone to deviation, further reducing the efficiency of coolant entering the grinding arc zone. This leads to increased temperature in the grinding area, affecting workpiece machining accuracy and surface quality.

[0004] Secondly, the grinding process continuously generates metal shavings, grinding wheel abrasive grains, and fine powder. These impurities mix with the coolant to form grinding slurry. Most existing equipment relies on natural flow or simple baffles for collection. Some of the grinding slurry tends to adhere to the surface of the spindle and workpiece, and then spreads again as the workpiece rotates. Others fly around the equipment, affecting not only the cleanliness of the equipment but also reducing the utilization rate of the coolant, resulting in poor chip removal in the grinding area.

[0005] Third, to achieve coolant recycling, existing grinding machines typically employ filtration structures such as screens and plates to separate grinding slurry. However, the large amount of grinding debris and impurities generated during grinding easily accumulates on the surface of the filtration structure, causing blockage of the filter pores. This leads to a decrease in recovery flow rate and efficiency, and in severe cases, even requires machine shutdown for cleaning. Existing filtration structures generally lack mechanisms for automatic cleaning and anti-clogging during equipment operation, resulting in poor long-term operational stability.

[0006] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a special grinding machine for spindle machining based on the control component, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses a special grinding machine for spindle machining based on a control component. By incorporating a C-shaped flow guide and recovery component, a fluid supply structure, and a floating support, the coolant can form a stable flow path on the outer cylindrical surface of the spindle workpiece and be guided along the workpiece surface to the grinding area between the grinding wheel and the workpiece. Simultaneously, the C-shaped flow guide and recovery component can float to compensate for dimensional errors, installation deviations, rotational runout, and thermal expansion of the spindle workpiece, thereby maintaining a stable flow clearance, improving the coolant's ability to enter the grinding contact area, reducing grinding temperature, minimizing thermal deformation, and improving the machining accuracy and surface quality of the spindle workpiece.

[0019] This invention discloses a special grinding machine for spindle machining based on a control component. By setting up a recovery structure and an elastic scraper that cooperates with the outer diameter of the spindle workpiece, it can promptly scrape off the coolant residue film, grinding mud, and grinding particles adhering to the surface of the spindle workpiece during the grinding process. With the help of negative pressure recovery, the grinding mud is quickly introduced into the recovery system, realizing the centralized collection of grinding fluid and grinding impurities, reducing grinding fluid scattering and impurity accumulation, improving the chip removal effect in the grinding area and the equipment operating environment.

[0020] This invention discloses a special grinding machine for spindle machining based on a control component. By setting a lower roller, a protrusion, a filter frame, and a reset component, the lower roller can periodically drive the filter frame to reciprocate as it rolls with the spindle workpiece. This allows the filter structure to be automatically cleaned using the existing motion source during equipment operation. It reduces the accumulation of grinding slurry and impurities on the filter frame surface without the need for an additional power mechanism, thereby reducing filter blockage and improving the long-term operational stability of the recovery system and the efficiency of coolant recycling.

[0021] This invention discloses a special grinding machine for spindle machining based on a control component. By utilizing the synergistic cooperation between a C-type flow guide and recovery component, a fluid supply structure, a recovery structure, and a filter anti-clogging structure, the coolant can complete a continuous process of flow cooling, grinding chip removal, slurry recovery, filtration separation, and recycling.

[0037] Preferred options are shown in the appendix. Figure 6 To be continued Figure 9 The housing 15 contains a cooling circulation system. Specifically, a cooling cylinder 21 is provided on the outside of the drive shaft 20, and a spiral channel 22 is formed inside the cooling cylinder 21. One end of the spiral channel 22 is connected to an external water pump. A cooling plate 23 is provided inside the dust cover 17. The other end of the spiral channel 22 is connected to one end of the cooling plate 23, and the other end of the cooling plate 23 is connected to the distribution chamber 36 through a delivery pipe 30, thereby forming a coolant delivery passage.

[0038] Preferred options are shown in the appendix. Figure 9 The lower part of the housing 15 is provided with a recovery tank 24, and a filter plate 25 is inclinedly arranged inside the recovery tank 24. One end of the recovery tank 24 is connected to the inlet end of the spiral channel 22 through a one-way valve 27, and the other end of the recovery tank 24 is equipped with a negative pressure water pump 26. The negative pressure water pump 26 is connected to the inside of the filter frame 43 through a recovery pipe 31. One end of the recovery pipe 31 is fixed to the lower support arm of the C-shaped flow guide recovery component 28. The filter frame 43 is covered outside the inlet end of the recovery pipe 31 to facilitate the suction and filtration of the recovered coolant and grinding mud.

[0039] Preferred options are shown in the appendix. Figure 6 The floating support 29 includes a fixed frame 32 and a movable frame 33. The fixed frame 32 is fixedly installed on the outside of the housing 15, and the movable frame 33 is fixedly connected to the C-shaped flow guide and recovery component 28. A pair of connectors 34 are cross-arranged between the fixed frame 32 and the movable frame 33. One end of each connector 34 slides vertically within the fixed frame 32, and the other end slides vertically within the movable frame 33, thereby forming a stable guiding structure.

[0040] Preferred options are shown in the appendix. Figure 2 To be continued Figure 6 The fixed frame 32 is connected to the corresponding ends of the movable frame 33 at both ends. The elastic element 35 is used to push the movable frame 33 towards the main shaft workpiece 13, so that the upper roller 39 and the lower roller 40 always maintain rolling contact with the outer circle of the main shaft workpiece 13. This allows the C-type flow guide and recovery component 28 to automatically generate floating compensation according to the size change, installation deviation, rotational runout and thermal expansion of the main shaft workpiece 13, and always maintain a stable flow guide gap.

[0041] Specific usage of this invention: Before processing begins, the operator installs the spindle workpiece 13 to be processed into the clamping and rotating mechanism 11 on the grinding machine body 10, and uses the control component 12 to adjust the relative position between the grinding wheel assembly 14 and the spindle workpiece 13, so that the grinding wheel 18 and the processing area of ​​the spindle workpiece 13 are set accordingly.

[0042] After adjustment, the cooling and chip removal assembly 19, located on one side of the grinding wheel assembly 14, is positioned close to the outer diameter of the spindle workpiece 13. At this time, the floating support 29 is connected to the housing 15 via a fixed frame 32, a movable frame 33, a pair of connecting parts 34, and a pair of elastic parts 35. Under the elastic force of the pair of elastic parts 35, the movable frame 33 drives the C-shaped flow guide and recovery part 28 to move towards the spindle workpiece 13, causing the upper roller 39 and lower roller 40 to roll into contact with the outer diameter of the spindle workpiece 13. Since the two ends of the pair of connecting parts 34 slide vertically within the fixed frame 32 and the movable frame 33 respectively, the movable frame 33 can float smoothly vertically. When the spindle workpiece 13 experiences installation deviations, dimensional errors, rotational runout, or thermal expansion, the upper roller 39 and lower roller 40 can roll along with the changing position of the outer diameter of the spindle workpiece 13, causing the movable frame 33 to float slightly relative to the fixed frame 32, thus ensuring that the C-shaped flow guide and recovery part 28 maintains a stable flow guide gap with the outer diameter of the spindle workpiece 13.

[0043] Subsequently, the clamping and rotating mechanism 11 drives the spindle workpiece 13 to rotate at high speed, and the drive motor 16 drives the drive shaft 20 and the grinding wheel 18 to rotate synchronously, and the grinding wheel 18 begins to perform grinding on the spindle workpiece 13.

[0044] Meanwhile, external coolant enters the spiral channel 22 under the action of a water pump. As the coolant flows along the spiral channel 22, it cools and dissipates heat from the interior of the housing 15 and absorbs the heat generated by the drive motor 16 and drive shaft 20 during operation. Subsequently, the coolant enters the cooling plate 23 to cool the area surrounding the grinding wheel 18. Afterward, the coolant enters the distribution chamber 36 through the delivery pipe 30 and is evenly sprayed out through several outlet holes 37.

[0045] Because several outlet holes 37 are oriented towards the outer circle of the spindle workpiece 13, the sprayed coolant first enters the guide gap formed between the C-shaped guide recovery member 28 and the spindle workpiece 13. Under the guidance of the arc-shaped guide section in the middle of the C-shaped guide recovery member 28, the coolant does not directly scatter, but forms a continuous liquid film along the outer circle of the spindle workpiece 13, and flows along the surface of the spindle workpiece 13 towards the grinding arc area between the grinding wheel 18 and the spindle workpiece 13.

[0046] Since the coolant enters the grinding arc area in the form of an attached liquid film, it can effectively overcome the airflow obstruction caused by the high-speed rotation of the grinding wheel 18, allowing more coolant to enter the actual grinding contact area, continuously cooling, lubricating and flushing the grinding area, thereby reducing the grinding temperature, reducing thermal deformation, and improving the machining accuracy and surface quality of the spindle workpiece 13.

[0047] During the grinding process, metal shavings, grinding wheel particles, and fine powder generated are carried by the coolant and together with the coolant form grinding slurry. The grinding slurry continues to flow downward along the outer circle of the spindle workpiece 13 and enters the corresponding area of ​​the lower support arm of the C-type guide recovery component 28.

[0048] When the grinding mud flows to the lower support arm area, it first passes through several elastic scrapers 47 arranged radially inside a set of arc-shaped baffles 45. One end of each elastic scraper 47 maintains slight contact with the surface of the spindle workpiece 13. During the rotation of the spindle workpiece 13, the elastic scrapers 47 can continuously scrape off the coolant residue, grinding mud, and metal particles adhering to the surface of the spindle workpiece 13 and guide them to the corresponding area of ​​the recovery pipe 31.

[0049] Meanwhile, the negative pressure water pump 26 continues to work, creating a negative pressure adsorption effect inside the recovery pipe 31. The filter frame 43, located at the inlet of the recovery pipe 31, blocks and filters large particles of grinding debris entering the recovery area, while coolant, fine grinding debris, and grinding slurry enter the recovery pipe 31 under negative pressure and are eventually transported to the recovery tank 24.

[0050] After entering the recycling tank 24, the coolant and grinding debris mixture flows through the filter plate 25 for filtration and separation. The grinding debris particles are intercepted and collected, and the filtered coolant re-enters the cooling cylinder 21 through the one-way valve 27, realizing the recycling of coolant, thereby reducing coolant waste and improving the continuous operation capability of the equipment.

[0051] To prevent grinding slurry and impurities from accumulating on the surface of the filter frame 43 and affecting the recovery effect, the lower roller 40 continuously rolls synchronously during the rotation of the main shaft workpiece 13. As the lower roller 40 rotates, it drives several protrusions 42 within the annular groove 41 to rotate synchronously, and these protrusions 42 sequentially contact the wear-resistant block 44. When the protrusions 42 contact the wear-resistant block 44, they push the filter frame 43 and a set of arc-shaped baffles 45 to move upwards in an arc along the inner wall of the C-shaped flow guide recovery component 28, simultaneously compressing the corresponding return spring 46.

[0052] As the filter frame 43 moves upward, the filtered coolant in the lower support arm washes over the lower area of ​​the filter frame 43, thereby removing grinding mud and impurities adhering to the lower part of the filter frame 43.

[0053] As the protrusion 42 continues to rotate and disengages from the wear-resistant block 44, the return spring 46 releases its elastic force, pushing the arc-shaped partition 45 and the filter frame 43 downwards in an arc-shaped reset. During the reset process, the coolant once again flushes the upper area of ​​the filter frame 43, thereby removing impurities adhering to the upper part of the filter frame 43.

[0054] Therefore, under the periodic pushing action of several protrusions 42 and the elastic force of the return spring 46, the filter frame 43 can continuously perform arc reciprocating motion along the inner wall of the C-shaped flow guide recovery component 28, thereby achieving automatic flushing and cleaning of the surface of the filter frame 43, reducing the accumulation of impurities, preventing the filter frame 43 from clogging, and improving the long-term operational stability of the recovery system.

[0055] At the same time, when a set of arc-shaped baffles 45 reciprocates, it drives several elastic scrapers 47 to reciprocate synchronously, so that the elastic scrapers 47 can continuously scrape different positions on the surface of the spindle workpiece 13, thereby further improving the removal effect of grinding mud and impurities.

[0056] In summary, this invention, through the cooperation of structures such as the C-shaped flow guide and recovery component 28, the floating support 29, the upper roller 39, the lower roller 40, the distribution cavity 36, the liquid outlet 37, the recovery pipe 31, the filter frame 43, and the arc-shaped baffle 45, achieves the functions of precise introduction of coolant into the grinding arc zone, timely recovery of grinding slurry, and automatic anti-clogging of the filter structure, thereby improving the cooling effect, chip removal effect, machining accuracy, and equipment operation stability during the spindle grinding process.
