It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here.

[0023] In order to solve the problems existing in the prior art, an automatic stripping and grinding tool is disclosed, which includes a stripping component and a fixed base plate 6, the stripping component includes an upper positioning plate 1, a product positioning core 2, a stripping plate 3, a fixed column 4 and a stripping cylinder 5, the upper positioning plate 1 is located above the stripping plate 3, the product positioning core 2 includes a first sliding part and a second sliding part arranged up and down, the first sliding part is slidably matched with the upper positioning plate 1, the top of the first sliding part is used to install the workpiece to be polished, the second sliding part is slidably matched with the product positioning core 2, and the first sliding part A transition step is formed between the second sliding part, one end of the fixed column 4 is connected to the upper positioning plate 1, and the other end of the fixed column 4 is slidably matched with the stripping plate 3. The stripping cylinder 5 is fixed to the fixed bottom plate 6 through a mounting bracket, and the stripping cylinder 5 is used to apply an ejection force to the stripping plate 3, so that the stripping plate 3 moves in a direction close to the upper positioning plate 1 relative to the product positioning core 2, so as to eject the target workpiece through the product positioning core 2 after contacting the transition step, wherein the target workpiece is the workpiece to be polished after polishing. In the example of the present application, by slidingly matching the positioning core and the stripping plate 3, after the stripping cylinder 5 pushes the stripping plate 3 to move upward relative to the product positioning core 2 and contacts the transition step newly placed on the product positioning, the product is ejected, so that the automatic stripping function of the workpiece can be realized, the removal speed of the workpiece is improved, the product scratch rate caused by manual workpiece removal in the prior art is reduced, and the quality of the polished product and the work efficiency of polishing and material removal are improved.

[0024] Specifically, in the initial state, the top of the product positioning core 2 can be 0-3mm higher than the upper plane of the upper positioning plate 1, so that the workpiece to be polished is installed on the top of the product positioning core 2 for easy polishing. When the stripping plate 3 is pushed upward by the stripping cylinder 5, the travel distance of the stripping cylinder 5 can make the product positioning core 2 be pushed out of the upper plane of the upper positioning plate 1 by 3-10mm, so as to facilitate the removal of the target workpiece. It can be understood that the above value range is only a preferred range, and in other feasible schemes, it can also be other ranges, which are not specifically limited here.

[0025] Furthermore, the stripping components are multiple groups, and the multiple groups of stripping components are arranged in parallel. Figures 1 to 3 As shown, the stripping components are five groups arranged in parallel. Specifically, when it is necessary to grind the workpiece, first prepare five products whose shapes and sizes match the product positioning core 2. Next, use the round holes on the product and the round holes on the upper positioning plate 1 on the tooling to make guide pins. These guide pins will be used to guide the rivets into the round holes of the product. Place the rivet at one end of the guide pin and make sure it is coaxial with the guide pin. Align the guide pin with the round hole on the product, then gently push the guide pin to make the rivet enter the round hole of the product. Then press the product to the bottom to ensure that they are aligned with the bottom of the product positioning core 2. Through the above working steps, the precise positioning of the product can be achieved to ensure the quality and production efficiency of the product. Adjust the height of the upper positioning plate 1 and the product positioning core 2 to the appropriate position, then start the triangular wire drawing machine and let it start grinding the product. After grinding is completed, start the stripping cylinder 5. Under the push of the stripping cylinder 5, the five stripping plates 33 will simultaneously approach the direction close to the product positioning core 2, and after contacting the transition step, the product positioning core 2 will be ejected, and the target workpiece will be ejected at the same time. Five products are ejected at the same time, so that five polished target workpieces can be quickly obtained, which improves the work efficiency of grinding and material removal. At the same time, the cooperation of the product positioning core 2 and the triangular wire drawing machine can ensure the stable positioning and consistency of the product during the grinding process. It can be understood that by arranging multiple groups of stripping components in parallel, multiple target workpieces can be demolded at the same time, which improves the material removal efficiency of the polished product.

[0026] Furthermore, in the above example, ejecting multiple target workpieces simultaneously is only a preferred implementation scheme. In other feasible schemes, the ejection cylinder 5 can also be selectively started to realize batch ejection of different target workpieces to meet different grinding requirements.

[0027] Further, the above-mentioned parallel arrangement of 5 groups of stripping components is only a preferred embodiment. In another feasible embodiment, as Figure 4 As shown, two groups of stripping components can also be arranged in parallel, or in another feasible solution, as Figure 5As shown, three groups of stripping components can be arranged in parallel. The specific number of groups can be set according to actual needs and is not specifically limited here.

[0028] Furthermore, a slidable piston rod 51 is also provided inside the stripping cylinder 5. The stripping plate 3 is connected to the piston rod 51 of the stripping cylinder 5 through a mechanical connector, and the stripping cylinder 5 pushes the stripping plate 3 to slide up and down relative to the product positioning core 2.

[0029] Furthermore, a first sliding hole is disposed on the upper positioning plate 1 , and a gap is set between the first sliding portion of the product positioning core 2 and the first sliding hole to achieve sliding fit between the first sliding portion and the upper positioning plate 1 .

[0030] Furthermore, the stripper plate 3 is provided with a second sliding hole, and a gap is provided between the second sliding portion of the product positioning core 2 and the second sliding hole to achieve sliding fit between the second sliding portion and the stripper plate 3 .
