Once the debris enters, it will accelerate the wear of equipment parts, cause electrical faults, and lead to frequent machine downtime for maintenance, significantly reducing production efficiency and increasing production costs. Therefore, an automated precision grinding device for stamping parts is proposed to solve the above problems. Summary of the Invention

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figure 1 - Figure 2 One embodiment of this utility model is an automated precision grinding device for stamped parts, including a CNC grinding machine 1. A grinding head 2 is provided on the inner side wall of the CNC grinding machine 1. The grinding head 2 can be moved vertically and horizontally by corresponding electronic control components (such as electric telescopic rods, electric slide rails, etc.) and perform grinding operations. This is prior art and will not be explained in detail here. A collecting mechanism 3 is provided on the inner bottom of the CNC grinding machine 1. The collecting mechanism 3 is provided to collect the chips during the grinding process and reduce the chips from splashing outward.
[0035] Reference Figure 2 - Figure 3 and Figure 5The collecting mechanism 3 includes a support column 302, with a base plate 301 fixedly connected to the top of the support column 302. The support column 302 supports the base plate 301, and the base plate 301 has multiple sets of circular through holes to facilitate the downward discharge of debris. Baffles 304 are rotatably connected to the front and rear sides of the base plate 301, and partitions 305 are rotatably connected to the left and right sides of the base plate 301. The partitions 305 and baffles 304 can be opened or closed as needed. When both are in the upright position, this prevents debris from splashing outwards. A connecting plate 308 is detachably installed on the movable end of the grinding head 2. A connecting hole matching the grinding head 2 is opened at the center of the connecting plate 308. Folding plates 307 are rotatably connected to the left and right sides of the connecting plate 308. The connecting plate 308 supports the folding plates 307, and the folding plates 307... The setup allows for horizontal movement of the grinding head 2. When the grinding head 2 moves horizontally, the folding plates 307 on both sides prevent chips from splashing out from above. A positioning plate 306 is rotatably connected to the side of the folding plate 307 away from the connecting plate 308. The positioning plate 306 supports the folding plate 307. A connecting piece is provided on the outer wall of the positioning plate 306. The connecting piece ensures that the positioning plate 306 and the connecting plate 308 are on the same horizontal line. A collection box 303 is in contact with the bottom of the inner side of the CNC grinding machine 1. The collection box 303 is located at the bottom of the base plate 301 to collect chips. A positioning pin 310 is fixedly connected to the bottom end of the positioning plate 306. Multiple sets of positioning pins 310 are provided. A disassembly mechanism 4 is provided at the top of the connecting plate 308. The disassembly mechanism 4 allows the collection mechanism 3 to be disassembled when not in use.
[0036] Reference Figure 2 - Figure 4 The connecting parts include a telescopic rod 309. The side of the telescopic rod 309 away from the grinding head 2 is fixedly connected to the top protrusion of the positioning plate 306, and the side of the telescopic rod 309 near the grinding head 2 is fixedly connected to the top protrusion of the connecting plate 308. The telescopic rod 309 ensures that the folding plate 307 is in a horizontal state and will not fall downwards. The rear end of the collection box 303 contacts the inner side wall of the CNC grinding machine 1, and the outer wall of the collection box 303 contacts the outer wall of the support column 302. The bottom end of the support column 302 is fixedly connected to the inner bottom of the CNC grinding machine 1. The contact setting ensures that the collection box 303 is in a stable state after installation. A set of round holes are opened at the top of the baffle 304 and the partition 305. The bottom end of the positioning pin 310 is inserted into the inner wall of the round hole. The insertion of the two can fix and limit the vertical state of the baffle 304 and the partition 305.
[0037] Reference Figure 3 , Figure 5 and Figure 6The disassembly mechanism 4 includes a limiting plate 402. The inner wall of the limiting plate 402 is elastically connected to a limiting post 405 via a connecting spring 404. The limiting post 405 has an inclined surface facing the grinding head 2. The inclined surface is designed to facilitate the pre-positioning of the connecting plate 308. The outer wall of the grinding head 2 is fixedly connected to a fixing block 401. Two sets of fixing blocks 401 are provided. The side of the limiting post 405 near the grinding head 2 is inserted into the inner wall of the fixing block 401. The insertion setting can achieve the positioning effect.
[0038] Reference Figure 3 , Figure 5 and Figure 6 One end of the connecting spring 404 is fixedly connected to the inner wall of the limiting plate 402, and the other end of the connecting spring 404 is fixedly connected to the outer arc surface of the limiting post 405. The outer wall of the limiting post 405 is slidably connected to the inner wall of the limiting plate 402. The elasticity of the connecting spring 404 enables the limiting post 405 to have the purpose of resetting and limiting. The bottom end of the limiting plate 402 is fixedly connected to the top end of the connecting plate 308. When the two are fixed, disassembling the limiting plate 402 is equivalent to disassembling the connecting plate 308. The limiting plate 402 is concave. The concave design allows the connecting plate 308 to move upward when it is installed. The inner wall of the limiting post 405 is threaded with a bolt 403. The side of the bolt 403 closest to the grinding head 2 is threadedly connected to the inner wall of the fixing block 401. The bolt 403 can fix the connecting plate 308.
[0039] Working principle: The operator places the collection box 303 under the base plate 301, with its rear end contacting the inner side wall of the CNC grinding machine 1 and its outer wall fitting against the outer wall of the support column 302, forming a stable placement to collect grinding debris. The operator rotates the baffles 304 on the front and rear sides of the base plate 301 and the partitions 305 on the left and right sides to the upright position, then starts the grinding head 2, causing the positioning pin 310 to move downwards until it inserts into the round holes at the top of the baffles 304 and partitions 305, fixing and limiting the vertically positioned baffles 304 and partitions 305 to prevent debris from splashing outwards during grinding. When the grinding head 2 moves horizontally, the folding plate 307 on one side will fold, while the folding plate 307 on the other side will open, thus adapting to the movement of the grinding head 2. Through the cooperation of the two folding plates 307, the top of the partition 305 is closed, preventing debris from splashing out from above. The splashed debris will be blocked and fall into the collection box 303 for directional collection.
[0040] When the grinding work is completed and the collecting mechanism 3 needs to be disassembled, first loosen the bolt 403 connected to the inner wall of the limiting post 405 so that the bolt 403 disengages from the inner wall of the fixing block 401. Then pull the limiting post 405 outward to release the insertion limit between the limiting post 405 and the fixing block 401. Then move the connecting plate 308 downward to remove it. During installation, move the connecting plate 308 upward. When the inclined surface of the limiting post 405 contacts the fixing block 401, the limiting post 405 moves away from the grinding head 2. When the connecting plate 308 moves to a certain extent, the elasticity of the connecting spring 404 causes the limiting post 405 to reset and insert into the fixing block 401, completing the pre-positioning. Then tighten the bolt 403 to complete the fixing.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
