[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces (stamped parts) of the desired shape and size. Stamping and forging both belong to plastic processing (or pressure processing) and are collectively referred to as forging and pressing. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Of the world's steel, 60-70% is sheet metal, most of which is stamped into finished products. Automobile bodies, chassis, fuel tanks, radiator fins, boiler drums, container shells, and silicon steel sheets for motor and electrical appliance cores are all produced by stamping. A large number of stamped parts are also found in instruments, household appliances, bicycles, office machinery, and household utensils.

Detailed Implementation

[0032] 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.

[0033] Please see Figures 1-4 The present invention provides the following technical solution: a stamping parts grinding device, including a cabinet 1 and a grinding fixture 3. The grinding fixture 3 is installed on the top of the cabinet 1. A protective box 2 is fixed on the top of the cabinet 1, and a door 21 is hinged to the front of the protective box 2. The grinding fixture 3 includes a material conveying mechanism 31 and a grinding mechanism 32.

[0034] Furthermore, by Figure 1 and Figure 2 As shown, in this embodiment, the material conveying mechanism 31 includes a multi-station rotary disk 311, a servo motor 312, and a three-jaw chuck 313. The multi-station rotary disk 311 is rotatably connected to the cabinet 1. The servo motor 312 is fixed on the cabinet 1 to drive the multi-station rotary disk 311 to rotate. Multiple three-jaw chucks 313 are fixed at equal intervals along the circumferential direction on the multi-station rotary disk 311. The grinding mechanism 32 includes an L-shaped fixing frame 321, a lifting plate 322, a rotating disk 323, a grinding disc 324, a first drive motor 325, and a drive mechanism 326. The L-shaped fixing frame 321 is fixed on the cabinet 1. The lifting plate 322 is movably connected to the L-shaped fixing frame 321. The rotating disk 323 is rotatably connected to the lifting plate 322. The first drive motor 325 is fixed on the lifting plate 322 to drive the rotating disk 323 to rotate. The grinding disc 324 is fixed to the rotating disk 323. The drive mechanism 326 drives the lifting plate 322 to move vertically. With the above scheme, when in use, the box door 21 is opened, and the stamped parts to be polished are placed in the three-jaw chuck 313 and clamped by the three-jaw chuck 313. Then, the servo motor 312 is started to drive the multi-station rotary table 311 to rotate. When the stamped parts are transferred to the underside of the polishing table 324, the servo motor 312 stops, and the drive mechanism 326 starts to drive the lifting plate 322 to move down. At the same time, the first drive motor 325 starts to drive the rotary table 323 to rotate, so that the polishing table 324 rotates to polish the stamped parts. After polishing, the drive mechanism 326 starts to drive the lifting plate 322 to rise, and the servo motor 312 restarts to drive the multi-station rotary table 311 to rotate. This cycle is repeated to polish all the stamped parts, greatly improving the processing efficiency.

[0035] It should be noted that the grinding device of this utility model is also applicable to production lines. In a production line, a belt conveyor can be used to transport the stamped parts. When the stamped parts are transported to the picking station, the robot automatically picks them up and places them in the three-jaw chuck 313. During this process, the servo motor 312 is started to drive the multi-station rotary table 311 to rotate, and all the stamped parts placed in the three-jaw chuck 313 are ground in sequence. It is worth noting that during the feeding process, when the stamped parts are transferred to the grounding disc 324, the servo motor 312 pauses and first grinds the stamped parts that have arrived at the grinding station. When the grinding is completed and the servo motor 312 restarts, the robot resumes the picking action.

[0036] In addition, it should be noted that during the grinding process, after the ground stamped parts are removed, the robotic arm is used to remove the ground stamped parts first, and then the new stamped parts are placed. The material handling and loading are completed during the grinding of other stamped parts, so it will not take up extra time.

[0037] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, a guide slide plate 3221 is fixed at the end of the lifting plate 322. The L-shaped fixing frame 321 has a guide slide hole 3211 through which the guide slide plate 3221 passes.

The threaded screw 3262 is rotatably installed between the two fixing plates 3261 and passes through the guide slide plate 3221 and is connected to the guide slide plate 3221 by threaded engagement. The second driving motor 3263 is fixed on the fixing plate 3261 and is used to drive the threaded screw 3262 to rotate. With the above scheme, when in use, the second driving motor 3263 is started to drive the threaded screw 3262 to rotate. Under the threaded engagement, the guide slide plate 3221 drives the lifting plate 322 to move in the vertical direction.

[0038] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, the outer wall of the guide slide plate 3221 abuts against the inner wall of the guide slide hole 3211 to improve the stability of the guide slide plate 3221 and prevent the guide slide plate 3221 from shaking.

[0039] Preferably, by Figure 1 and Figure 3As shown in this embodiment, the drive mechanism 326 further includes: guide posts 3264. Two guide posts 3264 are symmetrically fixed between two fixed plates 3261, and the guide posts 3264 penetrate the guide slide plate 3221. The two guide posts 3264 are used to guide the guide slide plate 3221, thereby further improving the stability of the guide slide plate 3221.

[0040] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, this embodiment also includes: a fixing post 3241, a flange 3242, and a locking bolt 327. The fixing post 3241 is fixed to the top of the grinding disc 324, the flange 3242 is fixed to the top of the fixing post 3241, and the locking bolt 327 passes through the flange 3242 and is fixed to the rotating disc 323 by thread engagement. With the above solution, the grinding disc 324 is fixedly installed by the flange 3242 and the locking bolt 327. Under the premise of ensuring stable installation, it is also convenient to disassemble, repair or replace the grinding disc 324.

[0041] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the three-jaw chuck 313 is fixed to the top surface of the multi-station rotary table 311 with bolts.
