Description

Technical Field

[0001] The utility model relates to the fields of mechanical manufacturing and automation, in particular to an automatic cutting fixture. Background Art

[0002] With the development of the modern mechanical processing industry, the requirements for cutting quality and precision are constantly increasing. At the same time, the demand for improving production efficiency, reducing production costs and realizing highly intelligent automatic cutting functions is also increasing. The development of automatic cutting fixtures must adapt to the development requirements of the modern mechanical processing industry. Traditional electric abrasive cutting machines require manual clamping of the cutting parts during use and manual release after the cutting is completed. This operation method has low working efficiency. By using an automated clamping mechanism, manual operation can be reduced and production efficiency can be improved.

[0003] In existing automatic cutting fixtures, in order to adapt to a variety of workpieces, the shape of the fixture usually cannot completely match the outer surface shape of the workpiece being processed, resulting in unstable clamping of workpieces with special shapes. During cutting, the position of the workpiece on the fixture may shift or vibrate under the force of the cutting blade. It is difficult for the automatic cutting machine to perform accurate deep cutting on the workpiece, which can easily damage the workpiece, affect production efficiency, and increase production costs. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide an automatic cutting fixture, in which the operator aligns the protruding structure on the side of the product to be cut with the position between insert one and insert two, and matches the shape of the top surface of insert one and insert two with the limit block to position the product on the lower pressure plate one, thereby limiting the position of the product in the horizontal direction. Then the operator turns on the cylinder to control the upper pressure plate two to descend to the top surface of the product, pressing the product and limiting the position of the product in the vertical direction. This makes the clamping of the processed product more stable and the deep cutting process more precise, thereby improving production efficiency and reducing production costs.

[0005] The utility model is achieved through the following technical solutions:

[0006] An automatic cutting fixture includes a lower die locking plate, a pressure block, and also includes lower pressure plate two and upper pressure plate one. The lower die locking plate is connected to the bottom surface of the internal shell of the automatic cutting machine, the lower pressure plate two is connected to the front top of the lower die locking plate, the top of the pressure block is connected to the cylinder output end of the automatic cutting machine, the upper pressure plate one is connected to the front of the pressure block, the top surface of the lower pressure plate two is connected to the lower pressure plate one, the top surface of the lower pressure plate one is connected to the insert one and the insert two, and the bottom surface of the upper pressure plate one is connected to the upper pressure plate two.

[0007] Furthermore, the lower die locking plate is connected to the bottom surface of the housing just in front of the cutting blade inside the automatic cutting machine.

[0008] Furthermore, the upper pressure plate 2 and the lower pressure plate 1 are arranged in the same vertical direction. When the cylinder output end of the automatic cutting machine is retracted to the uppermost end, the distance between the bottom surface of the upper pressure plate 2 and the top surface of the lower pressure plate 1 is greater than the width of the product.

[0009] Furthermore, the bottom surface of the upper pressing plate 2 is arc-shaped, which adapts to the side shape of the cylindrical body of the non-cutting part of the product.

[0010] Furthermore, the insert 1 and the insert 2 are parallel and relatively connected to the front and rear ends of the top surface of the lower pressing plate 1 respectively.

[0011] Furthermore, the distance between the opposing surfaces of the first insert and the second insert is equal to the length of the protruding structure on the cylindrical side surface of the non-cutting portion of the product.

[0012] Furthermore, the insert 1 includes a panel 1, the top surface of the panel 1 is connected with a embedding groove, and the shapes of the top surface of the panel 1 and the embedding groove connected to the top surface adapt to the shape of the edge portion with a protruding structure of the non-cutting part of the product.

[0013] Furthermore, insert 2 includes panel 2, the top surface of which is arc-shaped to adapt to the side shape of the column of the product close to the cutting part. The bottom of panel 2 opposite to insert 1 is connected to a limiting block, and the thickness of the limiting block is equal to the distance from the tail end of the product protruding structure to the positioning piece on the product protruding structure.

[0014] Furthermore, after the upper pressing plate 2 and the lower pressing plate 1 clamp the product, the position of the product to be cut is vertically aligned with the cutting blade in the automatic cutting machine.

[0015] Compared with the prior art, the present invention has the following obvious advantages:

[0016] 1. In the present invention, the distance between the opposite surfaces of insert 1 and insert 2 connected to the top surface of the lower pressure plate 1 is equal to the length of the protruding structure on the side of the column of the non-cutting part of the product, and the top surface shapes of insert 1 and insert 2 adapt to the shapes of the two ends of the protruding structure of the non-cutting part of the product, and the bottom of the side of panel 2 opposite to insert 1 is also connected to a limiting block. When the operator places the product on the two inserts, the protruding structure of the product can be accurately embedded between the two inserts, thereby realizing precise limitation of the horizontal position of the product.

[0017] 2. In the present invention, since the bottom of the upper pressure plate 2 is arc-shaped, it adapts to the cylindrical side shape of the non-cutting part of the product. After the product is positioned on the lower pressure plate 1, the operator turns on the cylinder in the automatic cutting machine, controls the pressure block connected to the output end of the cylinder and the upper pressure plate 1 and upper pressure plate 2 connected to the pressure block to descend to the top surface of the product, presses the product, and cooperates with the insert 1 and insert 2 connected to the top surface of the lower pressure plate 1 to effectively limit the position of the product in the vertical direction.

[0018] 3. The utility model uses the insert 1 and insert 2 connected to the top surface of the lower pressure plate 1 which adapts to the shape of the non-cutting part of the product and the upper pressure plate 2 to limit the product to be processed, so that the product to be processed can be clamped more stably and accurately, making the deep cutting process more accurate, improving the processing success rate, reducing the waste of processing materials, and helping to improve production efficiency and reduce production costs.
