Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 this utility model and are not intended to limit this utility model.

[0029] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a countersinking device for a car engine rear bracket, including a bottom box 1 that extends through both sides and the top. The through-holes on both sides facilitate the outward pulling of a storage box 2, while the through-hole at the top allows debris generated from drilling at the top to fall downwards into the storage box 2 for collection, reducing cleaning time after subsequent processing and improving work efficiency. The bottom box 1 contains a removable storage box 2, which collects and centrally processes debris through its upper opening. A controller 119 is installed on the outside of the bottom box 1, allowing operation of the electrical components within the device via an externally purchased controller 119, resulting in higher efficiency and greater convenience. Symmetrical "U"-shaped brackets are installed on the front and rear sides of the upper end of the bottom box 1, facilitating the insertion of the rear bracket for mounting. The design incorporates a rear support that is easily placed across the bottom of the support structure to bear force. A movable mechanism is installed at the upper end of the bottom box 1, allowing the supports to move back and forth, thus adjusting the spacing between them. This enables the placement of rear supports of different sizes, enhancing its practicality. The support structure includes a movable force-bearing plate 3 at the bottom, with a top sliding rod 4 mounted on the upper end of the movable force-bearing plate 3. A first pushing slider 10 is slidably connected to the top sliding rod 4. Connecting fixing rods 5 are provided on both sides of the movable force-bearing plate 3 and are fixed to the top sliding rod 4. The movable mechanism includes a first lead screw 6 rotatably mounted on one side of the upper end of the bottom box 1 via a bearing. The outer threads of the first lead screw 6 are mirrored on both sides of the middle, facilitating the movement of the supports on both sides inward or outward during rotation. The processing work is carried out by adjusting different spacings, and the positioning slide rod 8 is fixedly installed on the other side. One side of the moving force plate 3 is provided with a rotating threaded hole 7 that is rotatably connected to the first lead screw 6, so that the rotating threaded holes 7 of the two supports are respectively connected to the threads on both sides to achieve simultaneous movement. The other side of the moving force plate 3 is provided with a positioning slide hole 9 that is slidably connected to the positioning slide rod 8. This enhances the stability of the support and prevents it from falling. The positioning slide hole 9 and the positioning slide rod 8 can be set to rectangular or circular shapes to enhance their stability performance and make the support more stable during movement. The first motor 17 is installed on the outside of the bottom box 1 and connected to the first lead screw 6, so that the first motor 17 can rotate the first lead screw 6. Simultaneously, it drives the supports on both sides to move and adjust. Several first push sliders 10 are slidably installed at the upper end of the supports, allowing multiple rear supports to be fixed at once. This enables the processing of more rear supports, avoiding the low efficiency of single-unit processing and preventing the waste of time and low overall work efficiency caused by only replacing one part after stopping processing. A first electric push rod 13 is installed at the bottom of the first push slider 10, and a pressure plate 14 is connected to the output end of the first electric push rod 13. The first electric push rod 13 pushes the lower pressure plate 14 downward to press the rear supports placed horizontally on the two side supports, preventing instability during processing.To improve processing results, a pad 16 is mounted on the bottom surface of the pressure plate 14 via a pressure sensor 15. This allows the downward pressure to be monitored by the pressure sensor 15, preventing excessive downward force. The pad 16 can be made of rubber, providing friction and improving the clamping effect. A connecting threaded hole 11 is installed at the bottom of the first push slider 10, and a rotating screw 12 is rotatably connected inside the threaded hole 11. Rotation of the knob at the upper end of the rotating screw 12 causes the bottom to contact the top slide bar 4 via the rotating screw 12, applying force to it. This makes the first push slider 10 more stable during processing, preventing movement that could affect the drilling effect.

[0030] Please see Figure 4 Mounting plates 18 are installed on both sides of the front and rear ends of the bottom box 1. A movable slide rod 19 is connected to the top of the mounting plate 18. A push slide plate 110 is installed between the movable slide rods 19. The push slide plate 110 has movable sliding holes 111 on both sides that slide slidably with the movable slide rods 19, allowing workers to manually push the push slide plate 110 left and right to adjust the position of the countersink 118 for drilling. A fixed frame 112 with an open bottom is installed at the bottom of the push slide plate 110. A second lead screw 113 is installed inside the fixed frame 112 via a bearing. A second motor 114 is installed on the outside of the fixed frame 112 and connected to the second lead screw 113. A second push slider 115 is installed inside the fixed frame 112 and connected to the second lead screw 113, ensuring the second push slider 115 fits snugly against the inside of the fixed frame 112 to reduce wobbling during movement. The second motor 114 drives the second lead screw 113 to rotate, which in turn drives the second push slider 115 to move the countersink 118 back and forth. This movement of the upper end in all directions makes it easier to adjust the drilling position, resulting in higher work efficiency and enabling processing at different positions on the rear support. A countersinking assembly is installed at the bottom of the second push slider 115. The countersinking assembly includes a second electric push rod 116 installed at the bottom of the second push slider 115. A third motor 117 is installed at the output end of the second electric push rod 116 through the mounting box. The countersink 118 is installed at the output end of the third motor 117 through the mounting box. Different types of countersinks 118 can be replaced as needed. The height of the countersink 118 can be moved up and down by the second electric push rod 116 to process different positions, and the third motor 117 drives the countersink 118 to rotate and drill holes.

[0031] Working principle: In use, first connect the first electric push rod 13, pressure sensor 15, first motor 17, second motor 114, second electric push rod 116, and third motor 117 to the controller 119 and connect them to an external power supply. Then, with the first motor 17 driving the first lead screw 6 to rotate, the first lead screw 6 drives the moving force plates 3 on both sides and the top slide rod 4 to move, so that the moving force plates 3 move closer to each other. After the moving force plates 3 move closer, the rear bracket can be placed horizontally on both sides of the moving force plates 3, so that the rear bracket is suspended. Under the action of the moving first push slider 10, the bottom end... The pressure plate 14 is positioned at the upper end of the suspension point. Then, the first electric push rod 13 is pushed downwards, causing the pressure plate 14 to press and fix the rear bracket, preventing shaking during processing. During processing, the sliding plate 110 can be manually pushed to adjust the bottom countersink 118, allowing the countersink 118 to move to the marked position on the rear bracket for processing. The second electric push rod 116 pushes downwards, causing the third motor 117 to rotate the bottom countersink 118 for drilling. The second motor 114 drives the second lead screw 113, which in turn drives the second push slider 115 to adjust the countersink 118 to another position and direction, thereby completing the processing work.
