[0028] Example
[0029] like Figure 1-5 As shown, the processing tooling described in the embodiment of the present application includes a bottom plate 1, a top plate 2, a column 3 and a placement seat 4, the column 3 is arranged between the bottom plate 1 and the top plate 2, the placement seat 4 is arranged on the top plate 2, and the side of the placement seat 4 is provided with at least two groups of first pressing mechanisms 5, at least two groups of limiting mechanisms 6 and at least two groups of second pressing mechanisms 7, the first pressing mechanisms 5, the limiting mechanisms 6 and the second pressing mechanisms 7 are all arranged on the top plate 2, and the number of the limiting mechanisms 6 and the second pressing mechanisms 7 is the same and they are arranged one by one.
[0030] When in use, after the die-casting 19 is placed on the placement seat 4, the first pressing mechanism 5 is used to roughly position the die-casting 19, and then under the joint action of the limiting mechanism 6 and the second pressing mechanism 7, the ends of the die-casting 19 are fixed at different positions, so as to further improve the stability of the die-casting 19, avoid the deformation of the die-casting 19 affecting the CNC processing process, improve the quality stability and precision of the CNC process, and ensure the processing quality of the die-casting 19 products.
[0031] In this embodiment, the first pressing mechanism 5 includes a first cylinder 8, a first articulated seat 9, a first pressure block 10 and a first connecting rod 16. The first cylinder 8 and the first articulated seat 9 are both arranged on the top plate 2. The first pressure block 10 is hinged on the first articulated seat 9. One end of the first connecting rod 16 is hinged to the first pressure block 10, and the other end of the first connecting rod 16 is hinged to the telescopic end of the first cylinder 8. Under the driving action of the first cylinder 8, the first pressure block 10 rotates around the first articulated seat 9, so that the first pressure block 10 is close to or away from the placement seat 4.
[0032] When in use, after the die-casting 19 is placed on the placement seat 4, the first cylinder 8 is controlled to work. Under the driving action of the first cylinder 8, the first pressure block 10 rotates around the first hinge seat 9 to the side close to the die-casting 19, and stops after the first pressure block 10 contacts the die-casting 19, thereby fixing the local position of the die-casting 19 with stable flatness, thereby achieving rough positioning of the die-casting 19.
[0033] In this embodiment, two groups of first pressing mechanisms 5 are provided, and the two groups of first pressing mechanisms 5 are symmetrically distributed on both sides of the placement seat 4 to improve the positioning effect of the die-casting 19 .
[0034] In this embodiment, the second pressing mechanism 7 includes a second cylinder 11, a second articulated seat 12 and a second pressure block 13. The second cylinder 11 is arranged on the top plate 2. The second articulated seat 12 includes a fixed seat 17 and a second connecting rod 18. The fixed seat 17 is arranged on the top plate 2 or the second cylinder 11. One end of the second connecting rod 18 is hinged on the fixed seat 17, and the other end of the second connecting rod 18 is hinged to the second pressure block 13. The second pressure block 13 is hinged to the second cylinder 11. Under the driving action of the second cylinder 11, the second pressure block 13 rotates around the second articulated seat 12, so that the second pressure block 13 is close to or away from the limiting mechanism 6.
[0035] After the rough positioning of the die-casting 19 is completed, the limiting mechanism 6 is used to support and limit the die-casting 19, and then under the driving action of the second cylinder 11, the second pressing block 13 rotates around the second hinge seat 12 to the side close to the die-casting 19, and stops after the second pressing block 13 abuts against the die-casting 19, thereby fixing the end of the die-casting 19.
[0036] In this embodiment, four groups of second pressing mechanisms 7 are provided. The four groups of second pressing mechanisms 7 are distributed in a rectangular shape and adopt a multi-point fixing method to further improve the stability of the die-casting 19 .
[0037] In this embodiment, the limiting mechanism 6 includes a third cylinder 14 and a limiting column 15. The third cylinder 14 is installed on the top plate 2, and the third cylinder 14 drives the limiting column 15 to rise and fall.
[0038] After the die casting 19 is roughly positioned, the third cylinder 14 is controlled to work, and the third cylinder 14 drives the limiting column 15 to move upward, and stops after the limiting column 15 abuts against the die casting 19, supports and limits the lower end of the die casting 19, and then uses the second pressing mechanism 7 to fix the die casting 19. After the die casting 19 is processed, the third cylinder 14 drives the limiting column 15 to move downward, so that the limiting column 15 is away from the die casting 19.
[0039] In this embodiment, a plurality of columns 3 are provided to improve the stability of the connection between the bottom plate 1 and the top plate 2 .
[0040] The working principle of a processing tool in the embodiment of the present application:
[0041] After the die-casting 19 is placed on the placement seat 4, the first cylinder 8 is controlled to work. Under the driving action of the first cylinder 8, the first pressing block 10 rotates around the first hinge seat 9 to the side close to the die-casting 19, and stops after the first pressing block 10 abuts against the die-casting 19, fixes the local position of the die-casting 19 with stable flatness, and realizes the rough positioning of the die-casting 19, and then controls the third cylinder 14 to work. The third cylinder 14 drives the limiting column 15 to move upward, stops after the limiting column 15 abuts against the die-casting 19, supports and limits the lower part of the end of the die-casting 19, and then under the driving action of the second cylinder 11, the second pressing block 13 rotates around the second hinge seat 12 to the side close to the die-casting 19, and stops after the second pressing block 13 abuts against the die-casting 19, thereby fixing the end of the die-casting 19.
[0042] After the die-casting 19 is processed, the second cylinder 11 is controlled to work so that the second pressure block 13 rotates around the second hinge seat 12 to the side away from the die-casting 19, and the third cylinder 14 drives the limit column 15 to descend. Then, by controlling the first cylinder 8 to work, the first pressure block 10 rotates around the first hinge seat 9 to the side away from the die-casting 19, so that the die-casting 19 can be easily removed.
[0043] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
