[0030] Example 1:

[0031] like Figure 1-7 As shown, a workpiece angle cutting fixture for one-time clamping includes a base plate 1, a workpiece support mechanism 2 on the base plate 1, a clamping mechanism 3 on the workpiece support mechanism 2, the workpiece support mechanism 2 having displacement to drive the workpiece 5 to change angle, and angle limiting mechanisms 4 on both sides of the workpiece support mechanism 2 on the base plate 1.

[0032] In this embodiment, as a specific solution, the base plate 1 is provided with a bearing 11, and the workpiece support mechanism 2 is set on the bearing 11. The bearing 11 is used to drive the workpiece support mechanism 2 to move circumferentially. More specifically, the workpiece 5 is placed on the workpiece support mechanism 2, and the workpiece is clamped by the clamping mechanism 3. The workpiece support mechanism 2 rotates to the angle limiting mechanism 4, and the workpiece is cut by the saw blade, so that the cutting and angle processing of the workpiece can be realized at the same time.

[0033] In this embodiment, as a specific solution, the workpiece support mechanism 2 is provided with a handle 7 for driving its rotation.

[0034] In this embodiment, as a specific solution, the base plate 1 is provided with a rotating fixing mechanism 6, which is used to fix the workpiece support mechanism 2; more specifically, there are two rotating fixing mechanisms 6, which are located at two corners of the workpiece support mechanism 2 respectively. Before processing, when the workpiece support mechanism 2 is adjusted to be close to the angle limiting mechanism 4 on one side as a backing, the rotating fixing mechanism 6 at the opposite corner is tightened to quickly pre-tighten the workpiece support mechanism 2.

[0035] In this embodiment, as a specific solution, the workpiece support mechanism 2 is provided with a support disk 21, which includes an inner support disk 211 and an outer support disk 212. The workpiece 5 has a convex ring 51 structure, which is locked between the inner support disk 211 and the outer support disk 212 during processing.

[0036] In this embodiment, as a specific solution, the workpiece support mechanism 2 is composed of two symmetrical structures with a cutting groove 22 in the middle between the two symmetrical structures; more specifically, the two symmetrical structures can be processed separately, and when one of them is worn or damaged, it can be replaced separately without scrapping the whole structure, which can save equipment costs.

[0037] In this embodiment, as a specific solution, the workpiece support mechanism 2 is provided with workpiece positioning pins 7; more specifically, at least one workpiece positioning pin 7 is provided on each of the opposite corners of the workpiece support mechanism 2, and the workpiece is positioned by the workpiece positioning pins 7 after being placed on the workpiece support mechanism 2.

[0038] In this embodiment, as a specific solution, the clamping mechanism 3 is a rotatable pressure plate clamping mechanism.

[0039] In this embodiment, as a specific solution, the angle limiting mechanism 4 is symmetrically arranged on both sides of the workpiece support mechanism 2, located at two corners of the workpiece support mechanism 2, while the rotation fixing mechanism 6 is located at the other two corners of the workpiece support mechanism 2. During processing, when the workpiece support mechanism 2 is rotated to be close to one of the angle limiting mechanisms 4, the diagonal rotation fixing mechanism 6 is tightened, and the workpiece is cut by a saw blade. After cutting, the workpiece support mechanism 2 is rotated to be close to the other angle limiting mechanism 4, the diagonal rotation fixing mechanism 6 is tightened, and the workpiece is cut by a saw blade. In this way, the cutting and angle processing of the workpiece are realized simultaneously.

[0040] In this embodiment, as a specific solution, the angle limiting mechanism 4 adopts a limiting pin, which makes it easier to install and disassemble.

[0041] The working principle of this utility model is as follows:

[0042] Step 1: Install the tooling of this utility model on the worktable 9 of the sawing machine and install the angle limiting mechanism 4;

[0043] Step 2: Position the workpiece 5 to be processed on the workpiece support mechanism 2, and clamp the workpiece 5 with the clamping mechanism 3.

[0044] Step 3: Rotate and adjust the workpiece support mechanism 3 to be close to the first angle limiting mechanism 41 or the second angle limiting mechanism 42 as a backing, tighten the rotation fixing mechanism 6 diagonally opposite to the angle limiting mechanism, pre-tighten the workpiece support mechanism 3, and start the saw blade 10 to cut.

[0045] Step 4: Loosen the rotating fixing mechanism 6, rotate the workpiece support mechanism 3 in the opposite direction, and adjust it to be close to the first angle limiting mechanism 41 or the second angle limiting mechanism 42 on the other side as a support. Tighten the rotating fixing mechanism 6 diagonally opposite to the angle limiting mechanism again, and start the saw blade 10 to cut.
