Description

Technical Field

[0001] This invention belongs to the technical field of automotive engine parts processing equipment, and particularly relates to a boring machine for machining automotive engine cylinder heads. Background Technology

[0002] The cylinder head of an automobile engine is one of the core components of the engine. Its structure is complex and requires the machining of multiple high-precision hole systems, sealing end faces and other key features. Boring is the core process in the cylinder head manufacturing process, which directly affects the airtightness, power performance and service life of the engine.

[0003] Currently, existing automotive engine cylinder head boring equipment suffers from insufficient clamping stability. Some equipment uses rigid pressure plates to clamp the cylinder head, concentrating the clamping force in a localized area, which can easily lead to plastic deformation or surface damage. At the same time, some clamping mechanisms only clamp a single part of the cylinder head, which can cause vibration and displacement of the cylinder head during processing, affecting the boring accuracy and causing key indicators such as hole coaxiality and end face flatness to exceed the standards.

[0022] In one embodiment of the present invention, such as Figures 1-8 As shown, a boring machine for machining automotive engine cylinder heads is provided, including a lower frame 1, an upper frame 2, a positioning mechanism 4, a clamping mechanism 5, a cutting mechanism 6, and a blanking mechanism 7; The lower frame 1 is fixedly installed on the base; the lower frame 1 is equipped with a conveying mechanism 3 for conveying and supporting the cylinder head, and a positioning mechanism 4 for positioning the cylinder head; the upper frame 2 is equipped with a clamping mechanism 5 for pressing the cylinder head in conjunction with the conveying mechanism 3; the cutting mechanism 6 is installed on the base and located on the lower side of the lower frame 1; the unloading mechanism 7 is installed on the base. Positioning mechanism 4, clamping mechanism 5, cutting mechanism 6, and unloading mechanism 7 are arranged from right to left; The cutting mechanism 6 includes a fixed sawing assembly and a movable sawing assembly, which are mounted on a base; the fixed sawing assembly is located to the right of the movable sawing assembly. like Figure 2As shown, the clamping mechanism 5 includes a first clamping component 51, a second clamping component 52, and a third clamping component 53. Multiple sets of first clamping components 51 are symmetrically installed on the upper frame 2. The second clamping components 52 and the third clamping components 53 are installed on the upper frame 2. The second clamping components 52 and the third clamping components 53 are located between the first clamping components 51 and are distributed from right to left.

[0023] like Figure 2 As shown, the positioning mechanism 4 includes a side positioning component 41 and an end positioning component 42. Multiple sets of side positioning components 41 are mounted on the lower frame 1, and the end positioning components 42 are mounted on the base.

[0024] like Figure 2 As shown, the feeding mechanism 7 includes a moving component 71, an adjusting linear module 72, a material transfer component 73, and a placement platform 74. The moving component 71 is mounted on the base, and the adjusting linear module 72 is fixedly mounted on the base. The moving component 71 is provided with two sets, one set of material transfer components 73 is mounted on the base, and the other set of material transfer components 73 is mounted on the output end of the adjusting linear module 72. The placement platform 74 is located between the two sets of material transfer components 73. The placement platform 74 is fixedly mounted on the base.

[0025] The placement table 74 is equipped with a movable frame for supporting the slit cylinder head or a belt conveyor for transferring the cylinder head.

[0026] In this embodiment, when the boring equipment for machining automobile engine cylinder heads is working normally, the cylinder head is moved from right to left by the conveying mechanism 3. During this process, the side positioning component 41 positions the side of the cylinder head to ensure that the cylinder head moves in a straight line. When the cylinder head moves to the fixed sawing component, the first clamping component 51 clamps the cylinder head. Then, as the cylinder head continues to move, the fixed sawing component cuts the cylinder head along the middle position. After the cylinder head moves to the underside of the second clamping component 52, the second clamping component 52 clamps the cylinder head. This continues until the cylinder head moves to the position where it contacts the end positioning component 42, where the end positioning component 42 positions the cylinder head to ensure the sawing accuracy. At this point, the third clamping component 53... The cylinder head is pressed down, and then the cylinder head is cut by the moving sawing assembly. The moving direction of the moving sawing assembly is perpendicular to the moving direction of the cylinder head, and the sawing direction of the fixed sawing assembly is parallel to the moving direction of the cylinder head, so that the cylinder head is cut into two pieces at once, achieving high-speed and high-efficiency sawing. By adjusting the linear module 72, a set of material transfer assemblies 73 is moved, thereby changing the distance between the two sets of material transfer assemblies 73 to adapt to cylinder heads of different sizes. The third pressing assembly 53 is reset, the end positioning assembly 42 makes way, and the conveying mechanism 3 continues to move the sawn cylinder head to the moving assembly 71. The moving assembly 71 moves the cylinder head to the material transfer assembly 73, and the material transfer assembly 73 continuously stacks the sawn cylinder head to ensure that the stacking efficiency meets the requirements of high-speed sawing.

[0027] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figure 3 and Figure 4 As shown, the conveying mechanism 3 includes a first roller conveyor 31, a first support platform 32, a second support platform 33, and a second roller conveyor 34. The first roller conveyor 31, the first support platform 32, the second support platform 33, and the second roller conveyor 34 are fixedly installed on the base from right to left. The fixed sawing assembly is located to the left of the first roller conveyor 31, and the movable sawing assembly is located between the first support platform 32 and the second support platform 33.

[0028] like Figures 3-5As shown, the side positioning assembly 41 includes a guide rail 411, a guide seat 412, a side baffle 413, a threaded rod 414, and an adjusting wheel 415. Multiple guide rails 411 are symmetrically fixedly installed on the lower frame 1. Multiple guide seats 412 are fixedly installed on the lower side of the side baffle 413. The guide seats 412 are slidably connected to the guide rails 411. One end of the threaded rod 414 is rotatably connected to the side baffle 413, and the other end of the threaded rod 414 is fixedly installed with an adjusting wheel 415. The threaded rod 414 is threadedly connected to the lower frame 1 through a threaded sleeve. The end positioning assembly 42 includes a first cylinder linear module 421, an end baffle 422, and a fixed baffle 423. The first cylinder linear module 421 is fixedly installed on the base and is located between the second support platform 33 and the second roller conveyor 34. The output end of the first cylinder linear module 421 is fixedly installed with the end baffle 422. The fixed baffle 423 is fixedly installed on the left side of the second roller conveyor 34.

[0029] like Figure 6 As shown, the first pressing assembly 51 includes a second cylinder linear module 511, a first mounting frame 512, and a first pressure roller 513. The second cylinder linear module 511 is fixedly mounted on the upper frame 2. The output end of the second cylinder linear module 511 is fixedly mounted with the first mounting frame 512. The lower side of the first mounting frame 512 is rotatably mounted with the first pressure roller 513 for pressing the middle part of the cylinder head at equal intervals. The second pressing assembly 52 includes a third cylinder linear module 521, a second mounting bracket 522, and a second pressure roller 523. The third cylinder linear module 521 is fixedly mounted on the upper frame 2. The output end of the third cylinder linear module 521 is fixedly mounted with the second mounting bracket 522. The second pressure roller 523 is rotatably mounted on the lower side of the second mounting bracket 522. The third clamping assembly 53 includes a fourth cylinder linear module 531 and a pressure plate 532. The fourth cylinder linear module 531 is fixedly installed on the upper frame 2, and the pressure plate 532 is fixedly installed at the output end of the fourth cylinder linear module 531.

[0030] like Figure 2 and Figure 4 As shown, the fixed sawing assembly includes a fixed base 61 and a fixed sawing machine 62. The fixed base 61 is fixedly installed on the base, and the fixed sawing machine 62 is fixedly installed on the fixed base 61. The output end of the fixed sawing machine 62 is aligned with the middle of the cylinder head. The mobile sawing assembly includes a sawing line module 63 and a mobile sawing machine 64. The sawing line module 63 is fixedly installed on the base, and the mobile sawing machine 64 is fixedly installed on the moving end of the sawing line module 63. The fixed sawing machine 62 includes a support base, a drive motor, a transmission assembly, and a saw blade. The support base is fixedly mounted on a fixed base 61, and the drive motor is fixedly mounted on the support base. The output end of the drive motor is fixedly connected to the power input end of the transmission assembly, and the power output end of the transmission assembly is fixedly connected to the saw blade. The saw blade is rotatably mounted on the support base. The transmission assembly adopts a synchronous belt and synchronous belt pulley transmission structure. The mobile sawing machine 64 and the stationary sawing machine 62 have the same structure.

[0031] In this embodiment, when the conveying mechanism 3, positioning mechanism 4, pressing mechanism 5, and cutting mechanism 6 are working normally, the adjusting wheel 415 is rotated, which drives the threaded rod 414 to rotate. The threaded rod 414 drives the side baffle 413 to move horizontally under the limiting action of the guide rail 411 and the guide seat 412, thereby adjusting the position of the side baffle 413 so that the cylinder head is in contact with the side baffles 413 on both sides. The cylinder head is moved from right to left by the first roller conveyor 31 until it moves onto the first support platform 32. The first mounting bracket 512 and the first pressure roller 513 are moved vertically by the second cylinder linear module 511 until the first pressure roller 513 cooperates with the first support platform 32 to vertically press the cylinder head. At this time, the first roller conveyor 31 continues to move the cylinder head, and the fixed sawing machine 62 is started. The cylinder head is cut along the middle position of the cylinder head by a fixed sawing machine 62. After the cylinder head moves to the lower side of the second pressure roller 523, the third cylinder linear module 521 drives the second mounting bracket 522 and the second pressure roller 523 to move vertically downward, and the second pressure roller 523 presses the cylinder head tightly until the cylinder head moves to contact the end baffle 422. The fourth cylinder linear module 531 drives the pressure plate 532 to move vertically, and the pressure plate 532 cooperates with the second support platform 33 to press the cylinder head tightly to ensure the stability of the cylinder head. At this time, the sawing linear module 63 drives the moving sawing machine 64 to move horizontally, and the moving sawing machine 64 cuts the cylinder head. The moving direction of the moving sawing component is perpendicular to the moving direction of the cylinder head, and the sawing direction of the fixed sawing component is parallel to the moving direction of the cylinder head, so that the cylinder head is cut into two pieces at one time. After sawing is completed, the fourth cylinder linear module 531 drives the pressure plate 532 to reset, and the first cylinder linear module 421 drives the end baffle 422 to move vertically downward, so that the end baffle 422 no longer obstructs the movement of the cylinder head; the first support platform 32 continues to drive the cylinder head to move horizontally, so that the sawn cylinder head moves to the second roller conveyor 34, and the second roller conveyor 34 continues to drive the sawn cylinder head to move to the moving component 71.

[0032] Example 3: In some embodiments, as a preferred embodiment of the present invention, such as Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the moving component 71 includes a clearance hydraulic linear module 711, a first belt conveyor 712, and a second belt conveyor 713. The clearance hydraulic linear module 711 is fixedly mounted on the base. Multiple first belt conveyors 712 are evenly and uniformly fixedly mounted at equal intervals at the output end of the clearance hydraulic linear module 711. The first belt conveyors 712 are located below the second roller conveyor 34. The second roller conveyor 34 has a clearance inside for clearing the first belt conveyors 712. The second belt conveyor 713 is fixedly mounted on the base. The material transfer assembly 73 includes a fifth cylinder linear module 731, a sixth cylinder linear module 732, a seventh cylinder linear module 733, a material transfer mounting frame 734, and rollers 735. One set of fifth cylinder linear modules 731 is fixedly mounted on the base, and another set of fifth cylinder linear modules 731 is fixedly mounted on the moving end of the adjusting linear module 72. The sixth cylinder linear module 732 is fixedly mounted on the moving end of the fifth cylinder linear module 731, and the seventh cylinder linear module 733 is fixedly mounted on the moving end of the sixth cylinder linear module 732. The material transfer mounting frame 734 is fixedly mounted on the moving end of the seventh cylinder linear module 733. Multiple rollers 735 are evenly and rotatably mounted at equal intervals on the inner side of the material transfer mounting frame 734.

[0033] The drive component for the seventh cylinder linear module 733 is a multi-stroke cylinder.

[0034] In this embodiment, when the unloading mechanism 7 is working normally, a movable frame for supporting the cylinder head or a belt conveyor for transferring the cylinder head is placed on the placement platform 74. The second roller conveyor 34 drives the sawn cylinder head to move until it contacts the fixed baffle 423. At this time, the clearance hydraulic linear module 711 drives the first belt conveyor 712 to move vertically upward, so that the first belt conveyor 712 supports the cylinder head, and the cylinder head is no longer in contact with the second roller conveyor 34. The first belt conveyor 712 drives the cylinder head to move horizontally onto the second belt conveyor 713, and the second belt conveyor 713 drives a cylinder head to move horizontally. The roller 735 moves to the lower side of the cylinder head edge. At this time, the seventh cylinder linear module 733 drives the edge of the cylinder head upward. The cylinder head is lifted, and then the fifth cylinder linear module 731 drives the seventh cylinder linear module 733 horizontally via the sixth cylinder linear module 732 to the moving frame on the placement platform 74 or the belt conveyor for transferring the cylinder head. The seventh cylinder linear module 733 drives the material transfer mounting frame 734 and the roller 735 vertically until the bottom of the roller 735 contacts the lower cylinder head. At this time, the sixth cylinder linear module 732 drives the seventh cylinder linear module 733, the material transfer mounting frame 734 and the roller 735 to move horizontally to both sides of the cylinder head, so that the roller 735 is separated from the cylinder head. This operation is repeated to stack the cylinder head. In the process, the cylinder head is moved by the roller 735, so that the roller 735 rolls and contacts the cylinder head, completing the stacking while avoiding scratching the cylinder head.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
