[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] Example 1, please refer to Figures 1-8 This embodiment provides a reaming device for machining an engine cover, comprising a base 1; an arc-shaped seat 2, the arc-shaped seat 2 being fixedly connected to the upper end of the base 1; a rotating ring 3, the rotating ring 3 being slidably connected to the upper end of the arc-shaped seat 2, the arc-shaped seat 2 providing a sliding contact surface for the rotating ring 3, and providing a movable space for the rotating ring 3 through the sliding connection, so that the rotating ring 3 can rotate freely on the seat; a placement plate 4, the placement plate 4 being fixedly connected between the two rotating rings 3; and a mounting plate 8, the mounting plate 8 being fixedly connected to the upper end of the base 1; The inner side of the mounting plate 8 is rotatably connected with a threaded rod 51, the outer wall of the threaded rod 51 is threadedly connected with a moving cylinder 52, the outer wall of the moving cylinder 52 is movably sleeved with a moving seat 53, the interior of the moving seat 53 is provided with an accommodating cavity 54 and a through groove, the interior of the through groove and the accommodating cavity 54 are respectively slidably connected with a moving block 55 and a lifting block 56, the outer wall of the moving block 55 is provided with a V-shaped groove 57, the outer wall of the lifting block 56 is fixedly connected with a movable shaft 58, the movable shaft 58 is slidably connected to the interior of the V-shaped groove 57, the inner side of the moving seat 53 is rotatably connected with a positioning block 59, the positioning Block 59 is used to secure the engine cover during the reaming process, preventing it from moving or shifting during the reaming operation. One end of the movable cylinder 52 is fixedly connected to a connecting plate 510. A linkage rod 512 slides through the lower side of the connecting plate 510. A connecting rod 511 is fixedly connected to the bottom of the placement plate 4. One end of the linkage rod 512 is fixedly connected to the connecting rod 511. The outer wall of the movable cylinder 52 is provided with a limit groove 516. The bottom of the lifting block 56 is inserted into the interior of the limit groove 516. The limit groove 516 and the lifting block 56 form a mechanical interlock to control the clamping timing. The inner top of the accommodating chamber 54 is fixedly connected to a spring A513. The bottom of the spring A513 is fixedly connected to the lifting block 56. The end of the movable cylinder 52 away from the connecting plate 510 is fixedly connected to a limit ring 514. The threaded rod 51 movably passes through the limit ring 514. A telescopic rod 515 is fixedly connected to the inner side of the mounting plate 8. The other end of the telescopic rod 515 is fixedly connected to the movable seat 53. The outer wall of the base 1 is equipped with a lifting assembly 6 , and the interior of the base 1 is provided with a buffer assembly 7 .

[0027] When in use, first place the cover to be expanded on the inner side of the placing plate 4, and then start the external motor to drive the threaded rod 51 to rotate. Since the moving seat 53 is limited by the telescopic rod 515, and at the same time the lifting block 56 at the bottom of the internal accommodating chamber 54 of the moving seat 53 is inserted into the limiting groove 516 opened on the surface of the moving cylinder 52, then when the threaded rod 51 rotates, the moving cylinder 52 threadedly connected to the outer wall will move accordingly, and can drive the moving seat 53 to move. When one side of the moving block 55 inside the through groove opened by the moving seat 53 contacts the side surface of the cover layer, the moving seat 53 continues to move and pushes the moving block 55 to slide into the inside of the through groove, and then because the movable shaft 58 on the outer wall of the lifting block 56 is slidably connected to the V-shaped groove 57 of the moving block 55, and since the lifting block 56 cannot move horizontally, when the moving block 55 moves, the movable shaft 58 will slide from the lowest point of the V-shaped groove 57 to the top, thereby driving the lifting block 56 to move upward, which will make When the bottom of the lifting block 56 leaves the limit groove 516, when the lifting block 56 completely leaves the limit groove 516, the positioning block 59 on the side of the moving seat 53 will contact the outer wall of the machine cover to achieve the positioning of the machine cover, and at the same time, the motor stops driving the threaded rod 51. At this time, although the moving seat 53 is disconnected from the moving cylinder 52, the limiting ring 514 on one side of the moving cylinder 52 will prevent the moving seat 53 from moving outward, thereby ensuring its positioning stability. At this time, the hole enlarging operation can be carried out. When the hole enlarging is complete and the machine cover needs to be flipped to the other side, the motor is started again to drive the threaded rod 51 to rotate. At this time, since the moving cylinder 52 has lost its restriction, the moving cylinder 52 will rotate accordingly, and then drive the connecting rod 511 to rotate through the connecting plate 510, and then the connecting rod 511 will drive the placement plate 4 to rotate through the linkage rod 512. While rotating, the positioning block 59 still clamps the placement plate 4, but since it can rotate, it will not affect the rotation of the machine cover.

[0028] Example 2, please refer to Figures 1-8Based on Example 1, the lifting assembly 6 includes a fixed column 61, which is fixedly connected to both sides of the base 1. The fixed column 61 is slidably connected to the mounting bracket 62. A hydraulic chamber 63 is fixedly connected to the side of one side of the fixed column 61. Hydraulic rods A64 and B65 are slidably connected to the inside of the hydraulic chamber 63 via pistons. The other end of hydraulic rod A64 is fixedly connected to a movable rod 66. Hydraulic rod B65 is fixedly connected to the bottom of one side of the mounting bracket 62. The inner wall of the fixed column 61 on the other side is rotatably connected to an L-shaped rod 67 via a pin. The bottom of the other side of the mounting bracket 62 is fixedly connected to a toothed plate 613. A block 68 is fixedly connected to the top of the L-shaped rod 67. A spring B610 is fixedly connected to the bottom of one side of the L-shaped rod 67. A stop rod 69 is fixedly connected to the bottom of the connecting rod 511. The lifting assembly 6 also includes a vertical rod 611 and a fixed rod 612. The vertical rod 611 is fixedly connected to the upper end of the L-shaped rod 67, and the fixed rod 612 is fixedly connected to the outer wall of the placement plate 4 on one side. The movable rod 66 and the support rod 69 are in the same vertical plane, and the vertical rod 611 and the fixed rod 612 are in the same vertical plane.

[0029] When in use, when the linkage rod 512 drives the placement plate 4 to rotate, the push rod 69 at its bottom will also rotate accordingly. When the push rod 69 rotates to a certain angle, it will contact the movable rod 66. At this time, the push rod 69 continues to rotate to push the movable rod 66 in the opposite direction, and then the movable rod 66 will drive the hydraulic rod A64 to move inside the hydraulic warehouse 63. Then the hydraulic rod B65 inside the other end of the hydraulic warehouse 63 will push the mounting bracket 62 to rise. At this time, the bottom of the other side of the mounting bracket 62 will drive the tooth plate 613 to rise. When the teeth of the tooth plate 613 contact the block 68, it will push the L-shaped rod 67 to move around the pin axis to the outside at a certain angle, and then reset under the action of the spring B610, and the tooth plate 613 will suddenly fall. After 613 drives the block 68 to rotate and move a certain angle, it will abut against the tooth plate 613 itself, and the rotation angle of the L-shaped rod 67 in this direction is very small, which can prevent the mounting frame 62 from falling suddenly. When the placement plate 4 is about to be flipped over, the abutment rod 69 has already contacted the movable rod 66, and the fixed rod 612 will contact the top of the vertical rod 611, and then squeeze the vertical rod 611, so that the vertical rod 611 drives one end of the L-shaped rod 67 to squeeze the spring, and then the block 68 at the top of the other end of the L-shaped rod 67 will move away from the tooth plate 613, and then the mounting frame 62 can drop again after the placement plate 4 is flipped over, so that the reaming device at the bottom of the mounting frame 62 can reame again, avoiding the mounting frame 62 blocking the placement plate 4 from flipping over.

[0030] Example 3, please refer to Figures 1-8Based on Example 1, the buffer assembly 7 includes an L-shaped plate 71. A crossbar 72 is fixedly connected to the inner side of the L-shaped plate 71. A slider 73 is slidably connected to the outer wall of the crossbar 72. A connecting rod 74 is hinged to the upper end of the slider 73. The other end of the connecting rod 74 is hinged to a buffer plate 75. A spring C76 is fixedly connected to the inner side of the L-shaped plate 71 and the base 1. The other end of the spring C76 is fixedly connected to the buffer plate 75. The central axis of the buffer plate 75 is in the same vertical plane as the central axis of the stop rod 69. The central axis of the buffer plate 75 is in the same vertical plane as the central axis of the stop rod 69.

[0031] During use, the waste generated by the expansion hole will fall to the upper end of the buffer plate 75 to reduce the amount and avoid too large a splashing range. After the cover is expanded, the placement plate 4 is rotated to its original position, and the support rod 69 at the bottom of the linkage rod 512 will squeeze one end of the buffer plate 75, thereby causing the buffer plate 75 to tilt, thereby causing impurities to fall. At the same time, when the mounting bracket 62 falls and resets, the buffer rod 77 on the outer wall of the mounting bracket 62 will also fall and contact the buffer plate 75 before the mounting bracket 62 falls to the bottom. After being impacted, the buffer plate 75 will move to the lower end, and then drive the slider 73 to slide to both sides on the outer wall of the cross bar 72 through the connecting rod 74, and then the slider 73 will squeeze the spring C76, thereby achieving a buffering effect.

[0032] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
