Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical manufacturing, and particularly relates to a milling device for intelligent manufacturing of bearing covers. Background Art

[0002] In many mechanical devices, the bearing cover plays a crucial role. It is not only used to fix and protect the bearing housing, but also undertakes the important responsibility of maintaining the normal operation of the device. The main bearing cover, as a special form of the bearing cover, is commonly found in mechanical devices that require high precision and can withstand large loads, especially in engines, transmission systems, and heavy machinery. The main bearing cover is usually used to support the main shaft and bear the axial and radial loads generated during the operation of the machinery. In modern engineering technology, the design of the main bearing cover usually takes into account strength, rigidity, and durability. It needs to have high compressive resistance, be able to effectively prevent external impurities from entering the bearing interior, and maintain the lubrication state of the bearing to ensure the smooth operation of the device. In addition, the main bearing cover usually needs to be precisely matched with the bearing seat, the bearing itself, and other mechanical parts to maintain a stable geometric shape and good sealing performance.

[0003] Since the design of the inclined surface can improve the contact conditions and reduce the vibration and noise during mechanical operation on the contact surface between the main shaft and the bearing cover, inclined surfaces are provided on both contact surfaces of the main bearing cover. The existing milling devices for intelligent manufacturing of bearing covers usually require the cutting tool to perform milling on the two inclined slopes on one side of the main bearing cover in multiple steps and with tool direction changes during processing. Therefore, multiple devices are needed for milling, increasing the factory investment cost. At the same time, one milling device can only mill the inclined surfaces of the main bearing cover of one specification, resulting in great limitations in the processing process of the device, thereby reducing the working performance of the milling device for the main bearing cover. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a milling device for intelligent manufacturing of bearing covers.

[0005] The technical solution adopted to solve the above technical problem is: A milling device for intelligent manufacturing of bearing covers, including a main body, wherein a control mechanism for adjusting the height is installed inside the main body, and a milling mechanism is installed on the top of the control mechanism for performing back-and-forth milling on the double-sided inclined surfaces on the same side of the bearing cover during processing;

[0006] The milling mechanism includes a connecting shaft, and a first adjusting plate and a second adjusting plate for adjusting the inclination angle are respectively installed at both ends of the connecting shaft for manually adjusting the milling angle. A fixed seat is rotatably connected to the top of the second adjusting plate, and a milling driver is fixed inside the fixed seat. An adjusting mechanism is rotated on the top of the first adjusting plate for automatically adjusting the milling angle;

[0007] The adjusting mechanism includes a disc. A connecting rod is installed between the first adjusting plate and the disc. A rectangular seat slides on the surface of the disc, which is used to control the distance between the connecting rod and the first adjusting plate, thereby controlling the milling inclination angle.

[0008] A base is installed at the bottom of the main body. An intelligent control box for intelligently controlling the machining operation is installed on the outer surface of one end of the main body away from the milling mechanism.

[0009] Furthermore, a moving mechanism is installed on one side of the base away from the main body, which is used to detect the standard and perform reciprocating milling machining. The moving mechanism includes a bottom plate and a moving disc. End plates are installed at both ends of the top of the bottom plate and the moving disc. A positioning plate for separating the space is installed inside the bottom plate and the moving disc and between the two end plates. A machining platform slides at the bottom of the bottom plate and the moving disc. A first threaded rod for driving the sliding of the bottom plate and the moving disc is installed inside the machining platform. One end of the first threaded rod is installed with a first motor fixed on the surface of the machining platform. A plurality of main bearing covers separated by the positioning plate are installed inside the bottom plate and the moving disc.

[0010] Through the above technical solution, during use, the intelligent control box is used to control the programming in the prior art for milling machining, so that the milling machining can achieve automated machining. At the same time, when machining the main bearing cover, the moving mechanism is used to drive a plurality of main bearing covers to move reciprocally at this time. The purpose is to mill the two different inclined surfaces of the main bearing cover back and forth, and to provide time for the device to adjust the inclination angle during the moving process. Specifically, a plurality of main bearing covers are respectively placed in the bottom plate and the moving disc in groups by the positioning plate. When the inclined surface of the main bearing cover is milled, the first motor is started to drive the first threaded rod to rotate, thereby driving the bottom plate and the moving disc on the outer wall of the first threaded rod to slide along the machining platform, so as to ensure that a plurality of main bearing covers can be processed at a consistent inclination angle, making the specifications uniform. It should be understood that the bottom plate and the moving disc can accommodate a plurality of main bearing covers at the same time. The end plates limit the main bearing cover axially, and the reinforcing plates and the top plate on both sides of the end plates limit the main bearing cover radially, preventing the main bearing cover from shifting during the machining process, realizing rapid positioning, and being able to place a sample cover for comparison to facilitate controlling the size. Moreover, the positioning plate divides the bottom plate and the moving disc into two spaces. One space contains the sample cover and the eighth main bearing cover, and the other space contains the first to seventh main bearing covers, which is convenient for controlling the size.

[0011] Furthermore, the control mechanism includes a plurality of chutes opened on the inner wall of the main body. A plurality of placement plates slide inside the plurality of chutes. A second motor is installed on the top of the main body. The output end of the second motor is installed with a second threaded rod for driving the placement plate to move up and down.

[0012] Through the above technical solution, when the main bearing cap is placed and waiting for machining, the control mechanism can be used for preliminary adjustment at this time to ensure that the machining area is at the machining position of the inclined surface of the main bearing cap. At the same time, when switching to another inclined surface on the same side, since the heights of the two inclined surfaces are the same but only the inclination angles and surfaces are different, the control mechanism needs to adjust the height again to ensure that the machining position is accurate. Specifically, start the second motor to drive the placement plate on the second threaded rod to move up and down along multiple sliding grooves, and then the height of the machining tool can be adjusted.

[0013] Furthermore, a support plate is installed on the top of the placement plate, and a support ring is installed on the surface of the bent end of the support plate, which can be used to provide support when the milling driver slides. A tool is installed at the output end of the milling driver. A fixing plate is installed on the top of the placement plate on the side away from the support plate, and a third motor is installed on the surface of the fixing plate. The third motor drives the disc to drive the first adjustment plate at the other end of the connecting rod to swing, and then the second adjustment plate at the other end of the connecting shaft at the bottom of the first adjustment plate swings.

[0014] Through the above technical solution, when the machining height adjustment is completed, the milling mechanism can be used to adjust the machining position again. The purpose of this adjustment is to replace the two inclined surfaces on the same side of the main bearing cap, change the machining position, and during the adjustment process, the tool can be moved on the inclined surface of the main bearing cap to change the machining area of the tool and reduce wear. Specifically, start the third motor to drive the disc to drive the first adjustment plate at the other end of the connecting rod to swing. At this time, it will drive the second adjustment plate at the other end of the connecting shaft connected inside the first adjustment plate to swing. It should be noted that the inclination angle adjustment of the first adjustment plate and the second adjustment plate can change the inclination angle of the milling inclined surface. The larger the relative inclination angle adjustment of the first adjustment plate and the second adjustment plate, the larger the switching angle of the milling mechanism. As the second adjustment plate swings, at this time, it will drive the milling driver connected to the fixed seat to expand and contract and change the angle along the support ring. When the angle is determined, the milling driver will drive the tool to machine the inclined surface of the main bearing cap. It should be noted that when the connecting rod rotates to the lower right corner side away from the first adjustment plate on the disc, at this time, the internal inclined surface of the main bearing cap will be machined, and during the adjustment process, when the connecting rod is adjusted to the highest position on the disc, the milling inclined surface is switched, and at the same time, during the process of the semi-circle rotation, this is the process of the milling driver moving on the support ring.

[0015] Furthermore, a third threaded rod is installed inside the rectangular seat, and two strip-shaped grooves are opened on the surface of the disc. The third threaded rod rotates to drive the rectangular seat to move along the two strip-shaped grooves, thereby shortening the distance of the connecting rod. An iron plate is fixed on the surface of the disc at the top of the two strip-shaped grooves, and a fourth motor is installed on the surface of the iron plate. The third threaded rod is fixedly connected to the output end of the fourth motor, and the fourth motor drives the third threaded rod to rotate.

[0016] Through the above technical solution, when the milling of the inner inclined plane of the main bearing cap is completed, it can be switched at this time. Since the two inclined planes on the same side are of the same height but different surfaces, it is necessary to ensure that the cutting tool can fully contact the main bearing cap during the switching process. At this time, the adjusting mechanism is used for adjustment. Furthermore, during the switching process, it can be switched in two ways. It can be switched by rotation or by shortening the distance between the connecting rods, so that the first adjusting plate changes its angle, thereby ensuring the change of the milled inclined plane. Specifically, the fourth motor is started to drive the third threaded rod to rotate, driving the rectangular seat to move along the two strip grooves, thereby shortening the distance between the connecting rods, so as to realize the switching of the milled inclined plane.

[0017] The beneficial effects of the present invention are as follows: (1) By designing the moving mechanism, control mechanism, milling mechanism and adjusting mechanism, the present invention can use the same machine tool to process inclined planes in different directions according to the processing requirements of the main bearing cap during the milling process of the main bearing cap, and adjust according to the inclined angle of the inclined plane of the main bearing cap, thereby improving the working performance of the milling device; (2) When the main bearing cap is milled by the moving mechanism of the present invention, it can first ensure that the main bearing cap can move step by step during the milling process. When multiple main bearing caps are placed side by side, it can ensure that the processing standards of the main bearing caps are consistent. And through the base, multiple main bearing caps can be accommodated at the same time. The end plates limit the main bearing cap axially, and the reinforcing plates and top plates limit the main bearing cap radially, preventing the main bearing cap from shifting during the processing, realizing rapid positioning, and being able to place a sample cap for comparison to facilitate the control of dimensions; (3) Through the control mechanism, milling mechanism and adjusting mechanism, when the main bearing cap is milled, it can control the inclined angle of the inclined plane of the main bearing cap according to the specifications of the main bearing cap, and can polish the double-sided inclined planes on the same side, so that the same equipment can meet multiple processing operations of the main bearing cap, reducing the handling time, thereby reducing the factory input cost while improving the processing efficiency.

Detailed implementation manners

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] Such as Figures 1-7As shown in the figure, a milling device for intelligent manufacturing of bearing covers in this embodiment includes a main body 12. A base 11 is installed at the bottom of the main body 12. An intelligent control box 13 for intelligent control of machining operations is installed on the outer surface of one end of the main body 12 away from the milling mechanism 4. A moving mechanism 2 is installed on one side of the base 11 away from the main body 12 for detecting standards and milling back and forth. The moving mechanism 2 includes a bottom plate and a moving disk 24. End plates 25 are installed at both ends of the top of the bottom plate and the moving disk 24. A positioning plate 27 for separating spaces is installed between the inside of the bottom plate and the moving disk 24 and the two end plates 25. A machining platform 21 slides at the bottom of the bottom plate and the moving disk 24. A first threaded rod 23 for driving the sliding of the bottom plate and the moving disk 24 is installed inside the machining platform 21. A first motor 22 fixed to the surface of the machining platform 21 is installed at one end of the first threaded rod 23. A plurality of main bearing covers 26 separated by the positioning plate 27 are installed inside the bottom plate and the moving disk 24. During use, the milling machining is controlled by the intelligent control box 13 according to the programming in the prior art, so that the milling machining can achieve automated machining. At the same time, when machining the main bearing covers 26, the moving mechanism 2 is used to drive a plurality of main bearing covers 26 to move reciprocally. The purpose is to mill the two different inclined surfaces of the main bearing covers 26 back and forth, and to provide the device with time to adjust the inclination angle during the moving process. Specifically, a plurality of main bearing covers 26 are respectively placed in the bottom plate and the moving disk 24 by groups through the positioning plate 27. When milling the inclined surface of the main bearing cover 26, the first motor 22 is started to drive the first threaded rod 23 to rotate, and then drive the bottom plate and the moving disk 24 on the outer wall of the first threaded rod 23 to slide along the machining platform 21, so as to ensure that a plurality of main bearing covers 26 can be processed at a consistent inclination angle, making the specifications unified. It should be understood that the bottom plate and the moving disk 24 can accommodate a plurality of main bearing covers 26 at the same time. The end plates 25 limit the main bearing covers 26 axially, and the reinforcing plates and the top plate on both sides of the end plates 25 limit the main bearing covers 26 radially, preventing the main bearing covers 26 from shifting during the machining process, realizing rapid positioning, and being able to place sample covers for comparison to facilitate controlling the dimensions. And the positioning plate 27 divides the bottom plate and the moving disk 24 into two spaces. A sample cover and the eighth main bearing cover 26 are placed in one space, and the first to seventh main bearing covers 26 are placed in the other space, which is convenient for controlling the dimensions.

[0028] As Figure 3As shown, a height adjustment control mechanism 3 is installed inside the main body 12. The control mechanism 3 includes a plurality of sliding grooves 34 opened on the inner wall of the main body 12. A placement plate 33 is slidably arranged in each of the plurality of sliding grooves 34. A second motor 31 is installed on the top of the main body 12. The output end of the second motor 31 is provided with a second threaded rod 32 for driving the placement plate 33 to move up and down. When the main bearing cover 26 is placed and waiting for processing, the control mechanism 3 can be used for preliminary adjustment at this time to ensure that the processing area is at the processing position of the inclined surface of the main bearing cover 26. At the same time, when switching to another inclined surface on the same side, since the heights of the two inclined surfaces are the same but only the inclination angles and surfaces are different, the control mechanism 3 needs to adjust the height again to ensure that the processing position is accurate. Specifically, start the second motor 31 to drive the placement plate 33 on the second threaded rod 32 to move up and down along the plurality of sliding grooves 34, so that the height of the processing tool 49 can be adjusted.

[0029] As Figures 5-6As shown, a milling mechanism 4 is installed on the top of the control mechanism 3 for reciprocating milling of the same-side double-sided inclined surfaces of the bearing cover. The milling mechanism 4 includes a connecting shaft 45. At both ends of the connecting shaft 45, a first adjusting plate 44 and a second adjusting plate 46 for adjusting the inclination angle are installed to manually adjust the milling angle. The top of the second adjusting plate 46 is rotatably connected to a fixed seat 410. Inside the fixed seat 410, a milling driver 48 is fixed. On the top of the placement plate 33, a support plate 43 is installed. On the surface of the bent end of the support plate 43, a support ring 47 is installed, which can provide support when the milling driver 48 slides. The output end of the milling driver 48 is installed with a tool 49. On the top of the placement plate 33, on the side away from the support plate 43, a fixing plate 41 is installed. On the surface of the fixing plate 41, a third motor 42 is installed. By driving the disc 57 with the third motor 42, the first adjusting plate 44 at the other end of the connecting rod 56 swings. Furthermore, the second adjusting plate 46 at the other end of the connecting shaft 45 connected to the bottom of the first adjusting plate 44 swings. When the machining height adjustment is completed, at this time, the machining position can be adjusted again by using the milling mechanism 4. The purpose of this adjustment is to replace the two inclined surfaces on the same side of the main bearing cover 26, change the machining position, and during the adjustment process, the tool 49 can be moved on the inclined surface of the main bearing cover 26 to change the machining area of the tool 49 and reduce wear. Specifically, start the third motor 42 to drive the disc 57 to drive the first adjusting plate 44 at the other end of the connecting rod 56 to swing. At this time, the second adjusting plate 46 at the other end of the connecting shaft 45 connected inside the first adjusting plate 44 will be driven to swing. It should be understood that the adjustment of the inclination angles of the first adjusting plate 44 and the second adjusting plate 46 can change the inclination angle of the milled inclined surface. The greater the relative inclination angle adjustment of the first adjusting plate 44 and the second adjusting plate 46, the greater the switching angle of the milling mechanism 4. As the second adjusting plate 46 swings, at this time, the milling driver 48 connected to the fixed seat 410 will be telescoped and angled along the support ring 47. When the angle is determined, at this time, the milling driver 48 will drive the tool 49 to mill the inclined surface of the main bearing cover 26. It should be understood that when the connecting rod 56 rotates on the disc 57 to the side away from the lower right corner of the first adjusting plate 44, at this time, the inner inclined surface of the main bearing cover 26 will be milled, and during the adjustment process, when the connecting rod 56 is adjusted to the highest position on the disc 57, the switching of the milled inclined surface occurs. At the same time, during the semi-circular rotation process, this is the process of the milling driver 48 moving on the support ring 47.

[0030] As Figure 7As shown, a regulating mechanism 5 is rotatably mounted on the top of the first adjusting plate 44 for automatically adjusting the milling angle. The regulating mechanism 5 includes a disc 57. A connecting rod 56 is installed between the first adjusting plate 44 and the disc 57. A rectangular seat 54 is slidably mounted on the surface of the disc 57 for controlling the distance between the connecting rod 56 and the first adjusting plate 44, thereby controlling the milling inclination angle. A third threaded rod 53 is installed inside the rectangular seat 54. Two strip-shaped grooves 55 are formed on the surface of the disc 57. By rotating the third threaded rod 53, the rectangular seat 54 is driven to move along the two strip-shaped grooves 55, thereby shortening the distance of the connecting rod 56. An iron plate 51 is fixed on the surface of the disc 57 at the top of the two strip-shaped grooves 55. A fourth motor 52 is mounted on the surface of the iron plate 51. The third threaded rod 53 is fixedly connected to the output end of the fourth motor 52. The fourth motor 52 is used to drive the third threaded rod 53 to rotate. When the inner inclined surface of the main bearing cover 26 is milled, it can be switched at this time. Since the two inclined surfaces on the same side are of the same height but different surfaces, it is necessary to ensure that the cutter 49 can fully contact the main bearing cover 26 during the switching process. At this time, the regulating mechanism 5 is used for adjustment. Then, during the switching process, it can be switched in two ways. It can be switched by rotation or by shortening the distance of the connecting rod 56, so that the angle of the first adjusting plate 44 changes, thereby ensuring the change of the milled inclined surface. Specifically, the fourth motor 52 is started to drive the third threaded rod 53 to rotate, driving the rectangular seat 54 to move along the two strip-shaped grooves 55, thereby shortening the distance of the connecting rod 56, so as to realize the switching of the milled inclined surface.

[0031] The working principle of this embodiment is as follows. During use, intelligent control box 13 is used to control the programming in the prior art for milling processing, enabling the milling processing to achieve automated processing. Subsequently, multiple main bearing covers 26 are respectively placed in groups on the bottom plate and the moving plate 24 through the positioning plate 27. After that, the second motor 31 is started to drive the mounting plate 33 on the second threaded rod 32 to move up and down along multiple sliding grooves 34. After determining the processing height, the third motor 42 is started to drive the disc 57 to drive the first adjusting plate 44 at the other end of the connecting rod 56 to swing. At this time, the second adjusting plate 46 at the other end of the connecting shaft 45 connected inside the first adjusting plate 44 will be driven to swing. With the swing of the second adjusting plate 46, the milling driver 48 connected to the fixed seat 410 will be driven to expand and contract and change the angle along the support ring 47 at this time. When the angle is determined, the milling driver 48 will drive the tool 49 to perform milling bevel processing on the main bearing cover 26. At the same time, the first motor 22 is started to drive the first threaded rod 23 to rotate, thereby driving the bottom plate and the moving plate 24 on the outer wall of the first threaded rod 23 to slide along the processing platform 21, so as to ensure that multiple main bearing covers 26 can be processed at a consistent inclination angle. When the inner bevel processing is completed, the distance rotates in the reverse direction to drive multiple main bearing covers 26 to move in the reverse direction, and then the milling bevel processing is switched. The fourth motor 52 is started to drive the third threaded rod 53 to rotate, driving the rectangular seat 54 to move along two strip-shaped grooves 55, thereby shortening the distance of the connecting rod 56 until multiple main bearing covers 26 are processed.

[0032] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
