Description

Technical Field

[0001] The utility model belongs to the technical field of machining, and is a variable machining tooling. Background Art

[0002] In the original machining field, when a numerically controlled gantry milling machine processes double-curved aluminum profiles, one kind of part requires one kind of tooling for fixation. When processing a series of parts with similar structures but different sizes, a large number of toolings need to be made, and the installation of toolings is time-consuming and laborious, increasing the manufacturing cost of workpieces. Summary of the Invention

[0003] The utility model is a variable machining tooling improved according to the disadvantages of the need for a large number of toolings in the field of machining series aluminum profiles in the background art.

[0004] Its characteristics are as follows: It includes a machine tool table, a tooling column, cushion blocks, rubber pressing blocks, pressing plates, nuts, screw rods, columns, and workpieces to be machined. The tooling column is installed on the machine tool table, and the left, middle, and right cushion blocks are respectively fixed on the tooling column. The placement positions and quantities of the tooling column and the cushion blocks depend on the machining positions and lengths of the workpieces. The cushion blocks are made of hard wood, with low cost and easy to machine. The rubber pressing blocks can be in close contact with the upper curved surface of the workpiece without machining, firmly pressing the workpiece without damaging it. The tooling column is installed at a position where there is no interference between the tool and the tooling during machining. Before machining, the heights of the workpieces to be machined are sorted in ascending order. First, the workpieces with smaller heights are machined. The three-dimensional data of the corresponding positions to be fixed of the workpieces to be machined are extracted, and this data is used as the basis for programming the machining of the upper surfaces of the corresponding cushion blocks. After the upper surfaces of the cushion blocks are machined, the workpieces to be machined are placed on the cushion blocks, and rubber pressing blocks are placed on the workpieces at the positions of the tooling column. Then, by using the combination of the pressing plate, column, screw rod, and nut, the nut is rotated to fix the workpieces to be machined. The workpieces are machined according to the machining program. After machining is completed, the workpieces are taken out, and the above procedure is repeated to machine the second workpiece. The characteristic of sorting the series of parts in ascending order of height for machining is that the cushion blocks are machined successively, and the workpieces are machined successively. The machining amount of each cushion block is small during the machining of a batch of series parts. The number of toolings is reduced, and the auxiliary time and cost are also significantly reduced.

[0005] The utility model has a simple structure and a short process time, and can realize the machining of series parts quickly and at low cost. Brief Description of the Drawings

[0006] The following further describes the utility model with reference to the drawings.

[0009] The tooling column 2 is installed on the machine tool table 1. The left, middle, and right pads 3 are respectively fixed on the tooling column 2. The placement positions and quantities of the tooling column 2 and the pads 3 depend on the machining positions and lengths of the workpieces. The pads 3 are made of hard wood, which has low cost and is easy to process. The rubber pressing block 4 can be in close contact with the curved surface of the workpiece without machining, firmly pressing the workpiece without damaging it. The tooling column 2 is installed at a position where there is no interference between the tool and the tooling during machining. Before machining, the arc heights of the workpieces to be machined 9 are sorted in ascending order. First, the workpieces with smaller arc heights are machined. The three-dimensional data of the corresponding positions to be fixed for the workpieces to be machined 9 are extracted, and this data is used as the basis for programming the machining of the upper surfaces of the corresponding pads 3. After the upper surfaces of the pads 3 are machined, the workpieces to be machined 9 are placed on the pads 3, and the rubber pressing blocks 4 are placed on the workpieces at the position of the tooling column 2. Then, by using the combination of the pressing plate 5, the column 8, the screw 7, and the nut 6, the nut 6 is turned to fix the workpieces to be machined 9. The workpieces are machined according to the machining program. After machining is completed, the workpieces are taken out, and the above procedure is repeated to machine the second workpiece. The characteristic of machining a series of parts by sorting the arc heights in ascending order is that the pads are machined successively, the workpieces are machined successively, the machining amount of each pad during each machining is small. For the machining of a batch of series parts, the number of toolings is reduced, and the auxiliary time and cost are also significantly reduced.
