[0001] The present invention relates to the technical field of part processing, and in particular to an automatic tooling for a wall-piercing hole cover that can be trimmed. Background Technique

[0002] The wall-piercing hole cover is mainly used in the construction and electrical fields. In the construction field, such as the wall-piercing holes for the indoor and outdoor connection wires of air conditioners, pipe wall-piercing holes, flue wall-piercing holes in kitchens and bathrooms, etc., which play the roles of beautification, covering, and blocking. In the electrical field, it is used for sealing the holes where electrical cable trays, cables, etc. pass through shafts, walls, floors or enter electrical panels and cabinets to achieve functions such as fire prevention and moisture prevention.

[0003] In the prior art, during the installation process of the wall-piercing hole cover, problems such as size mismatch may occur. Generally, the wall-piercing hole cover needs to be trimmed, but most of the existing trimming methods adopt manual operations, with low efficiency and unstable trimming effects. Therefore, the present invention provides an automatic tooling for a wall-piercing hole cover that can be trimmed. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic tooling for a wall-piercing hole cover that can be trimmed to solve the problems raised in the above background technique.

[0005] The technical solution of the present invention is: an automatic tooling for a wall-piercing hole cover that can be trimmed, including an installation bottom box. Inside the installation bottom box, there is a fixedly connected installation bottom plate. On the top of the installation bottom plate, there is a fixedly connected adjustment motor. Inside the installation bottom box, there is a rotatably connected upper toothed ring. At the bottom of the upper toothed ring, there is a fixedly connected connection chassis, and the connection chassis is fixedly connected to the output end of the adjustment motor. On the top of the installation bottom box, there is a fixedly connected support bottom plate. At the bottom of the support bottom plate, there are two fixedly connected connection pillars. At the bottom of the connection pillar, there is a fixedly connected limit chassis. On the top of the limit chassis, there are two fixedly connected limit support columns. At the top of the limit support column, there is a fixedly connected limit outer ring. Inside the limit outer ring, there is a rotatably connected fixed drum. On the outside of the fixed drum, there is a fixedly connected adjustment toothed ring, and the adjustment toothed ring meshes with the top of the upper toothed ring. On the top of the limit chassis, there are two fixedly connected limit inner groove plates. Inside the limit inner groove plate, there is a slidably clamped adjustment groove column. One end of the adjustment groove column is threadedly connected to the fixed drum, and the other end of the adjustment groove column is fixedly connected to an installation hole plate. On the top of the installation hole plate, there is a slidably clamped installation plug. On the top of the installation plug, there is a fixedly connected trimming blade. The installation plug is slidably clamped inside the support bottom plate. On the top of the support bottom plate, there is a fixedly connected installation inner column. On the top of the installation inner column, there is a threadedly connected installation top cover. The trimming blade is clamped inside the installation inner column; during use: insert the installation plug downward through the top of the installation inner column into the top of the installation hole plate, and fix the top through the installation top cover for limiting. Place the hole cover to be trimmed outside the installation inner column. Through the adjustment motor, drive the connection chassis and the upper toothed ring to rotate. The upper toothed ring drives the adjustment toothed ring to rotate, driving the fixed drum to rotate. The limit chassis is fixed through the connection pillar, and the fixed drum is limited by the limit outer ring. Also, because the adjustment groove column is limited by the limit inner groove plate, the two adjustment groove columns move away from each other, causing the two installation plugs and the trimming blades to move away from each other, making the two trimming blades contact the inner wall of the hole cover, causing the hole cover to rotate for inner wall trimming, and at the same time controlling the distance between the two trimming blades to control the inner diameter of the inner circle.

[0006] Preferably, a placement outer ring is fixedly connected to the top of the limit chassis. Four trapezoidal pressing plates are slidably clamped inside the placement outer ring. One end of each trapezoidal pressing plate is fixedly connected to a fixed pressing ring. Two reset pull columns are fixedly connected to the side of the fixed pressing ring adjacent to the trapezoidal pressing plate. The reset pull columns are slidably clamped inside the placement outer ring, and a reset spring is fixedly connected to the end of each reset pull column away from the fixed pressing ring. A support column foot is fixedly connected to the outside of the installation bottom box. The top of the support column foot is fixedly connected to an installation top plate. A rotating motor is fixedly connected to the top of the installation top plate. The output end of the rotating motor is fixedly connected to a rotating chassis. A connecting sliding column is fixedly connected to the top of the rotating chassis. A protective top ring is fixedly connected to the top of the connecting sliding column. The protective top ring is rotatably connected to the bottom of the installation top plate. A rotating connecting disk is movably sleeved outside the connecting sliding column. A rotating connecting column is fixedly connected to the bottom of the rotating connecting disk. A rotating pressing ring is fixedly connected to the bottom of the rotating connecting column. Four inclined grooves adapted to the trapezoidal pressing plates are formed in the bottom of the rotating pressing ring. Two fixed electric cylinders are fixedly connected to the inside of the installation top plate. The output end of each fixed electric cylinder is fixedly connected to a downward-pushing ring. The downward-pushing ring is rotatably connected to the top of the rotating connecting disk. When in use: The rotating motor is started to control the rotation of the rotating chassis, driving the connecting sliding column to rotate, driving the rotating connecting disk to rotate, driving the rotating pressing ring to rotate. By pushing with the fixed electric cylinder, the downward-pushing ring is pushed downward, pushing the rotating connecting disk downward, so that the rotating pressing ring presses the trapezoidal pressing plate. By pushing the fixed electric cylinder to squeeze the hole cover for fixation, the hole cover is fixed. The rotation of the rotating pressing ring drives the hole cover to rotate for trimming. Similarly, the positions of the fixed pressing ring and the trimming blade can be swapped to trim the outer ring. After completion, it is released by the reset of the reset spring.

[0007] The present invention provides an automatic tooling for a wall-piercing hole cover that can be trimmed. Compared with the prior art, it has the following improvements and advantages:

[0008] First: For the automatic tooling for a wall-piercing hole cover that can be trimmed according to the present invention, the installation insertion block is inserted downward through the top of the installation inner column into the top of the installation hole plate, and the top is fixed by the installation top cover for limitation. The hole cover to be trimmed is placed outside the installation inner column. By adjusting the motor, the connecting chassis and the upper tooth ring are driven to rotate. The upper tooth ring drives the adjusting tooth ring to rotate, driving the fixed rotating cylinder to rotate. The limit chassis is fixed through the connecting support column. The fixed rotating cylinder is limited by the limit outer ring. Also, because the adjusting groove column is limited by the limit inner groove plate, the two adjusting groove columns move away from each other, causing the two installation insertion blocks and the trimming blades to move away from each other, making the two trimming blades contact the inner wall of the hole cover, causing the hole cover to rotate for inner wall trimming, and simultaneously controlling the distance between the two trimming blades to control the inner diameter of the inner ring.

[0009] Second: For the automatic tooling for a trim - able wall - piercing hole cover of the present invention, when the rotating motor starts, it controls the rotation of the rotating chassis, drives the connecting sliding column to rotate, drives the rotating connecting disk to rotate, drives the rotating pressure ring to rotate. Through the pushing of the fixed cylinder, the lower - pushing ring is pushed downward, the rotating connecting disk is pushed downward, so that the rotating pressure ring presses the trapezoidal pressing plate. By pushing the fixed cylinder to squeeze the hole cover for fixation, the hole cover is fixed. The rotation of the rotating pressure ring drives the hole cover to rotate for trimming. Similarly, the positions of the fixed pressure ring and the trimming blade can be swapped to trim the outer ring. After completion, it is released by the reset of the reset spring.

[0010] Summary: The automatic tooling for a trim - able wall - piercing hole cover of the present invention realizes automatic trimming, greatly improving the trimming efficiency and quality. Specifically, it realizes the automatic trimming of the inner and outer walls of the wall - piercing hole cover, and the trimming diameter can be flexibly adjusted, with a wide range of applications. In addition, the tooling has a compact structure, is easy to operate, and is easy to maintain and repair, with high practical value. Brief Description of the Drawings

On the top of the installation inner column 13, an installation top cover 14 is threadedly connected. The trimming blade 23 is clamped inside the installation inner column 13. When in use: Insert the installation insert block 22 downward through the top of the installation inner column 13 into the top of the installation hole plate 21, and fix the top through the installation top cover 14 for limiting. Place the hole cover to be trimmed outside the installation inner column 13. Through the adjustment motor 8, drive the connection chassis 9 and the upper toothed ring 10 to rotate. The upper toothed ring 10 drives the adjustment toothed ring 19 to rotate, driving the fixed rotating cylinder 18 to rotate. The limit chassis 12 is fixed through the connection support columns 11, and the fixed rotating cylinder 18 is limited by the limit outer ring 17. Also, because the adjustment groove column 20 is limited by the limit inner groove plate 16, the two adjustment groove columns 20 move away from each other, causing the two installation insert blocks 22 and the trimming blades 23 to move away from each other, making the two trimming blades 23 contact the inner wall of the hole cover, causing the hole cover to rotate for inner - wall trimming, and at the same time controlling the distance between the two trimming blades 23 to control the inner - ring diameter.

The upper gear ring 10 drives the adjustment gear ring 19 to rotate, driving the fixed rotating cylinder 18 to rotate. The limit chassis 12 is fixed through the connection support column 11. The fixed rotating cylinder 18 is limited by the limit outer ring 17. Also, because the adjustment groove column 20 is limited by the limit inner groove plate 16, the two adjustment groove columns 20 move away from each other, causing the two installation insert blocks 22 and the trimming blades 23 to move away from each other, making the two trimming blades 23 contact the inner wall of the hole cover, causing the hole cover to rotate for inner wall trimming. At the same time, control the distance between the two trimming blades 23 to control the inner diameter of the inner ring. The rotation motor 4 is started to control the rotation of the rotation chassis 30, driving the connection sliding column 31 to rotate, driving the rotation connection disk 33 to rotate, driving the rotation pressure ring 35 to rotate. By the push of the fixed electric cylinder 5, push the lower push ring 29 downward, push the rotation connection disk 33 downward, so that the rotation pressure ring 35 presses the trapezoidal pressing plate 28, and fix the hole cover by pushing and squeezing the hole cover with the fixed electric cylinder 5. Rotate the rotation pressure ring 35 to drive the hole cover to rotate for trimming. Similarly, the positions of the fixed pressure ring 26 and the trimming blade 23 can be swapped to trim the outer ring. After completion, release it by resetting with the reset spring 27.
