Description

Technical Field

[0001] This invention relates to the field of milling machine technology, specifically to a horizontal lifting milling machine for machining cylinder liners. Background Technology

[0002] The cylinder liner is a crucial component inside the cylinder block of an internal combustion engine. It is a cylindrical, thin-walled sleeve that fits into the cylinder bore of the cylinder block. The main functions of the cylinder liner include: reducing wear: bearing the friction and wear of the piston during reciprocating motion, protecting the cylinder block, and extending engine life. Cooling: helping to dissipate the heat generated by piston movement, ensuring the engine operates at its normal operating temperature. Facilitating maintenance and replacement: when the cylinder liner is severely worn, it can be replaced individually instead of the entire cylinder block, reducing maintenance costs.

[0003] In the process of machining cylinder liners using a milling machine, cutting technology is required. During cutting, coolant is needed for cooling. The coolant used during cutting may atomize into oil mist, which not only affects the air quality of the working environment, but may also adhere to the electrical components of the machine tool, causing potential malfunctions.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention, through the setting of a spindle mechanism, uses a main motor to drive the spindle speed change device, which in turn rotates the milling cutter on the output port, thereby slotting the cylinder liner on the placement mechanism. Simultaneously, the cooling mechanism at the bottom also starts working, and the nozzle sprays coolant from the storage plate onto the slotted area, thereby reducing the temperature of the milling cutter and cylinder liner at the slotted area, preventing damage to the steel and milling cutter due to excessive temperature. At the same time, the sprayed coolant splashes after contacting the milling cutter, and the splashed coolant carries the debris generated during slotting to impact the collecting arc plate. The splashed debris then accumulates at the bottom of the collecting arc plate, and the coolant enters the flow plate through the drain port on the side plate. After entering the filter box, the oil-absorbing cotton absorbs the oil stains accumulated by the coolant during the splashing atomization process and its movement along the collecting arc plate, and finally returns to the storage plate, thus forming a recycling.

[0018] 2. This invention, through the setting of a main shaft mechanism, causes the servo motor two to drive the motor shaft and gear one to reciprocate at a certain angle, thereby driving gear two to rotate and causing the transmission plate to sieve the iron filings in the collecting arc plate, preventing the iron filings from clogging the drain. At the same time, the bottom support plate three is also driven to swing, thereby causing the brush to brush the top of the nozzle, preventing small pieces of debris from falling to the edge of the nozzle and into the nozzle when the nozzle is not spraying coolant, thus preventing damage to the nozzle. After the grooving is completed, the telescopic rod will drive the disc to extend and brush the milling cutter with the wire. This not only uses conductivity to attract away the static and electromagnetic force generated by the milling cutter during grooving, but also facilitates the subsequent use of coolant to flush the debris on the milling cutter onto the collecting plate one.

[0019] 3. By setting up a vertical placement mechanism, when the cylinder liner needs to be placed on the placement platform with the port facing down, the placement plate is slid to a specific position on the placement platform by the limiting action of the locking block and the locking block. Then, by attaching the bottom of the cylinder liner to the placement plate, the rotating plate is rotated to a position parallel to the placement plate. After that, by rotating the threaded rod, the pressing plate is attached to the bottom of the cylinder liner, thereby fixing the cylinder liner and preventing it from moving during slotting.

[0020] 4. This invention uses a horizontal placement mechanism to place the cylinder liner onto the support frame via an auxiliary mechanism. During the grooving process, if the cylinder needs to rotate to change the grooving position, the servo motor will drive the rotating rod to rotate, thereby causing the rubber rotating block to generate a rotational force against the outer wall of the cylinder liner, thus causing the cylinder liner to rotate. During this process, the fan blades will generate a certain amount of wind force, causing the debris generated during grooving to splash towards the collection plate, preventing these debris from splashing onto the cylinder liner and causing scratches.

[0021] 5. By setting up a cleaning mechanism, at the end of all processes, the extrusion block is placed into the groove between the positioning block and the placement plate. Then the magnetic plate will attract the magnetic block, thereby driving the extrusion block to move along the groove and pushing the debris in the groove into the second collection plate. At the same time, the scraping plate will also scrape the debris that falls on the positioning block into the second collection plate. Attached Figure Description

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0038] Example 1, using Figures 1-14 The following describes a horizontal lifting milling machine for machining cylinder liners according to one embodiment of the present invention.

[0039] like Figures 1-3As shown, a horizontal lifting milling machine for cylinder liner machining according to the present invention includes a base 1, a bed 2 fixedly connected to the top of the base 1, a main motor 3 fixedly connected to the back of the bed 2, an auxiliary mechanism 4 fixedly connected to the outer surface of the base 1, an operating table 5 fixedly connected to the outer surface of the bed 2, a lifting platform 6 provided on the top of the operating table 5, a placement mechanism 7 fixedly connected to the top of the lifting platform 6, a sliding saddle 11 provided at the end of the operating table 5 away from the bed 2, a lifting button 12 provided on the outer surface of the lifting platform 6, a feed speed change device 10 fixedly connected to the outer surface of the operating table 5, a cantilever beam 9 fixedly connected to the top of the bed 2, a spindle speed change device 13 provided on the bed 2, and a spindle mechanism 8 fixedly connected to the output end of the spindle speed change device 13.

[0040] When a horizontal lifting milling machine for machining cylinder liners is working, the main motor 3 first drives the spindle speed change device 13 to operate and drives the spindle mechanism 8 to work. The cylinder liner to be machined is placed on the placement mechanism 7 through the auxiliary mechanism 4, and then the spindle mechanism 8 will machine the cylinder liner.

[0041] like Figures 9-11 As shown, the spindle mechanism 8 includes an end plate 81. An output port 82 is fixedly connected to the inner wall of the end plate 81. A milling cutter 83 is fixedly connected to one end of the output port 82. A servo motor 84 is fixedly connected to the outer surface of the end plate 81. A motor shaft 85 is fixedly connected to the output end of the servo motor 84. A gear 86 is fixedly connected to the end of the motor shaft 85 away from the servo motor 84. A cooling mechanism 87 is fixedly connected to the outer surface of the output port 82. A collar 88 is rotatably connected to the end of the output port 82 near the milling cutter 83. A gear 89 is rotatably connected to the collar 88. Telescopic rods 810 are evenly arranged on the inner wall of the output port 82. A disc 811 is fixedly connected to one end of the telescopic rod 810. Wires 812 are evenly arranged on the inner wall of the disc 811.

[0042] Servo motor 84 drives motor shaft 85 and gear 86 to reciprocate at a certain angle, which in turn drives gear 89 to rotate and causes transmission plate to screen iron filings in collection arc plate 875, preventing iron filings from clogging the drain. At the same time, support plate 8712 at the bottom is also driven to swing, causing brush 8713 to brush the top of nozzle 873, preventing small pieces of debris from falling to the edge of nozzle 873 and into the interior of nozzle 873 when it is not spraying coolant, thus preventing damage to nozzle 873. After grooving is completed, telescopic rod 810 drives disc 811 to extend and wire 812 to brush milling cutter 83. This not only attracts the electrostatic force generated by milling cutter 83 during grooving through conductivity, but also facilitates the subsequent use of coolant to flush the debris on milling cutter 83 onto collection plate 77.

[0043] like Figures 11-13As shown, the cooling mechanism 87 includes a pendant plate 871, a liquid storage plate 872 fixedly connected to the outer surface of the pendant plate 871, a nozzle 873 fixedly connected to the outer surface of the liquid storage plate 872, a support rod 874 fixedly connected to the top of the output port 82, a collecting arc plate 875 fixedly connected to the top of the support rod 874, side plates 876 symmetrically arranged on both sides of the collecting arc plate 875, a drain port 877 provided on the side plate 876, a flow plate 878 fixedly connected to the outer surface of the side plate 876, the bottom of the flow plate 878 fixedly connected to the outer surface of the liquid storage plate 872, a filter box 879 fixedly connected to the flow plate 878, oil-absorbing cotton 8710 provided on the inner wall of the filter box 879, a slidably connected scraper plate 8711 on the inner wall of the collecting arc plate 875, a support plate 8712 fixedly connected to the bottom of the gear 89, and brushes 8713 evenly arranged on the bottom of the support plate 8712.

[0044] The main motor 3 drives the spindle speed change device 13 to rotate and the milling cutter 83 on the output port 82 to rotate, thereby slotting the cylinder liner on the placement mechanism 7. At the same time, the cooling mechanism 87 at the bottom will also start to work. The nozzle 873 will spray the coolant in the liquid storage plate 872 onto the slotted area, thereby reducing the temperature of the slotted area of ​​the milling cutter 83 and the cylinder liner, and preventing the steel and the milling cutter 83 from being damaged due to excessive temperature.

[0045] The sprayed coolant splashes after contacting the milling cutter 83. The splashed coolant carries the debris generated by the grooving and impacts the collecting arc plate 875. The splashed debris then accumulates at the bottom of the collecting arc plate 875. The coolant enters the flow plate 878 through the drain port 877 on the side plate 876. After entering the filter box 879, the oil absorbent cotton 8710 absorbs the oil stains accumulated by the coolant during the splashing atomization process and during its movement along the collecting arc plate 875. Finally, it enters the storage plate 872 again, thus forming a recycling process.

[0046] The outer surface of the end plate 81 is fixedly connected to the outer surface of the bed 2, the end of the output port 82 away from the milling cutter 83 is fixedly connected to the spindle speed change device 13, and the top of the drooping plate 871 is fixedly connected to the bottom of the output port 82.

[0047] Gear 1 86 and Gear 2 89 mesh with each other, and the bottom of the shovel plate 8711 is fixedly connected to the top of Gear 2 89.

[0048] like Figure 14As shown, the auxiliary mechanism 4 includes a support frame 41. An operation box 42 is fixedly connected to the outer surface of the support frame 41. A guide device 43 is symmetrically arranged on the top of the support frame 41. A guide rod 44 is fixedly connected to the inner wall of the guide device 43. A guide device 45 is slidably connected to the outer surface of the guide rod 44. A guide rod 46 is fixedly connected to the inner wall of the guide device 45. A moving block 47 is slidably connected to the outer surface of the guide rod 46. A retractable device 48 is fixedly connected to the bottom of the moving block 47. A stabilizing rope 49 is rotatably connected to the inner wall of the retractable device 48.

[0049] Guide device 1 43 and guide device 2 45 work together to slowly move the cylinder liner on the stabilizing rope 49 under the take-up and release device 48 to the placement mechanism 7, which facilitates subsequent processing.

[0050] The bottom of the support frame 41 is fixedly connected to the outer surface of the base 1.

[0051] The specific workflow is as follows:

[0052] During operation, the main motor 3 drives the spindle speed change device 13 to rotate, causing the milling cutter 83 on the output port 82 to rotate, thereby slotting the cylinder liner on the placement mechanism 7. At the same time, the cooling mechanism 87 at the bottom also starts to work, and the nozzle 873 sprays the coolant in the storage plate 872 onto the slotted area. The sprayed coolant splashes after contacting the milling cutter 83, and the splashed coolant carries the debris generated by the slotting to the collecting arc plate 875. The splashed debris then accumulates at the bottom of the collecting arc plate 875, and the coolant enters the flow plate 878 through the drain port 877 on the side plate 876. After entering the filter box 879, it is absorbed by the oil-absorbing cotton 8710. The coolant was atomized during the splashing process and along the flow plate. The oil stains accumulated during the movement of the collection arc plate 875 are finally returned to the liquid storage plate 872. At the same time, the servo motor 84 drives the motor shaft 85 and the gear 86 to reciprocate at a certain angle, which in turn drives the gear 89 to rotate and causes the transmission plate to sieve the iron filings in the collection arc plate 875 to prevent the iron filings from clogging the drain. Meanwhile, the bottom support plate 8712 is also driven to swing, so that the brush 8713 brushes the top of the nozzle 873 to prevent small pieces of debris from falling to the edge of the nozzle 873. The telescopic rod 810 drives the disc 811 to extend and the wire 812 to brush the milling cutter 83. The wire 812 can not only attract away the electrostatic force generated by the milling cutter 83 when it is slotting through conductivity.

[0053] Example 2, using Figures 1-14 The following describes a horizontal lifting milling machine for machining cylinder liners according to one embodiment of the present invention.

[0054] like Figure 4 and Figure 6 As shown, a horizontal lifting milling machine for cylinder liner machining according to the present invention, based on embodiment one, includes a placement mechanism 7 comprising a placement table 71, a knob 72 on the outer surface of the placement table 71, a locking block 73 evenly distributed on the top of the placement table 71, the bottom of the locking block 73 being fixedly connected to the top of the placement table 71, a vertical placement mechanism 75 slidably connected to the inner wall of the locking block 73, a horizontal placement mechanism 76 slidably connected to the inner wall of the locking block 73, a cleaning mechanism 74 slidably connected to the top of the placement table 71, a collection plate 77 fixedly connected to one end of the placement table 71 near the bed 2, a collection plate 78 fixedly connected to one end of the placement table 71 away from the knob 72, and a magnetic plate 79 fixedly connected to the outer surface of the collection plate 78.

[0055] like Figure 7 As shown, the reclining placement mechanism 76 includes a placement plate 761, a locking block 762 fixedly connected to the bottom of the placement plate 761, a support plate 763 fixedly connected to the outer surface of the placement plate 761, a rotating shaft 764 rotatably connected to the top of the support plate 763, rotating plates 765 fixedly connected to both ends of the rotating shaft 764, a threaded rod 766 threadedly connected to the inner wall of the rotating plate 765, and a pressing plate 767 fixedly connected to the bottom of the threaded rod 766.

[0056] When the cylinder liner needs to be placed on the placement platform 71 with the port facing down, the placement plate 761 is slid to a specific position on the placement platform 71 by the limiting action of the locking block 762 and the locking block 73. Then, the bottom of the cylinder liner is brought into contact with the placement plate 761, and the rotating plate 765 is rotated to a position parallel to the placement plate 761. After that, the pressing plate 767 is brought into contact with the bottom of the cylinder liner by the rotation of the threaded rod 766, thereby fixing the cylinder liner and preventing it from moving during the grooving process.

[0057] like Figure 8 As shown, the vertical placement mechanism 75 includes a second placement plate 751, a second locking block 752 fixedly connected to the bottom of the second placement plate 751, a placement rack 753 fixedly connected to the top of the second placement plate 751, a support column 754 fixedly connected to the outer surface of the second placement plate 751, a second support plate 755 fixedly connected to the end of the support column 754 away from the second placement plate 751, a first servo motor 756 fixedly connected to the inner wall of the second support plate 755, a rotating rod 757 fixedly connected to the output end of the first servo motor 756, a rubber rotating block 759 fixedly connected to the outer surface of the rotating rod 757, and a fan blade 758 fixedly connected to the end of the rotating rod 757 near the first servo motor 756.

[0058] The cylinder liner is placed onto the support frame via the auxiliary mechanism 4. During the grooving process, if the cylinder needs to be rotated to change the grooving position, the servo motor 756 will drive the rotating rod 757 to rotate, thereby causing the rubber rotating block 759 to generate a rotational force against the outer wall of the cylinder liner, thus causing the cylinder liner to rotate. During this process, the fan blade 758 will generate a certain amount of wind force, causing the debris generated during grooving to splash towards the collecting plate 77, thus preventing these debris from splashing onto the cylinder liner and causing scratches to the cylinder liner.

[0059] like Figure 5 As shown, the cleaning mechanism 74 includes an extrusion block 741, a scraping plate 742 symmetrically arranged on the top of the extrusion block 741, a magnetic block 743 fixedly connected to the outer surface of the extrusion block 741, and the bottom of the scraping plate 742 slidably connected to the top of the locking block 73.

[0060] At the end of all processes, by placing the extrusion block 741 into the groove between the positioning block 73 and the placement plate, the magnetic plate 79 will attract the magnetic block 743, thereby moving the extrusion block 741 along the groove and pushing the debris in the groove into the collection plate 78. At the same time, the scraping plate 742 will also scrape the debris that falls on the positioning block 73 into the collection plate 78.

[0061] The bottom of the placement platform 71 is fixedly connected to the top of the lifting platform 6, the bottom of the placement plate 1 761 is slidably connected to the top of the locking block 73, the top of the placement plate 2 751 is fixedly connected to the top of the locking block 73, and the bottom of the extrusion block 741 is slidably connected to the top of the placement platform 71.

[0062] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
