Description

Technical Field

[0002] Positioning fixtures are indispensable auxiliary tools in modern machining, widely used in turning, milling, drilling, grinding and other processes. They are mainly used to fix the workpiece to be processed on the machining equipment and ensure its positional accuracy during the machining process. The function of positioning fixtures is to accurately and stably fix the workpiece on the machine table or fixture, ensuring repeatability and accuracy during the machining process. Especially in mass production, positioning fixtures can greatly improve production efficiency and machining quality.

[0003] Existing technologies, such as the utility model patent with publication number CN219027327U, disclose a positioning clamp. This patent includes a base, an alignment mechanism, a drive mechanism, and a transfer mechanism. The base has a placement area for placing a first and / or a second part to be assembled. The alignment mechanism includes multiple alignment members arranged around the placement area. The drive mechanism is connected to the alignment members and drives them to move closer to or away from the placement area to clamp and align the first or second part to be assembled. The transfer mechanism includes a movable component and a suction cup connected to each other. The movable component is located on the base or to the side of the base, and the suction cup is located above the placement area. The suction cup can move the aligned first and second parts to be assembled up or down under the action of the movable component. The positioning clamp provided by this utility model can effectively ensure the alignment and fit between the first and second parts to be assembled, avoiding uneven gaps around the edges after fitting.

[0004] In daily use, it has been found that when using traditional clamps to hold parts to be cut, manual clamping is usually used. Workers need to manually adjust the clamp to fix the workpiece according to its shape and size. This operation is not only cumbersome and time-consuming, but also prone to human error due to the fact that the adjustment of the clamp usually depends on the operator's experience and skills, resulting in unstable clamping. In addition, traditional clamps usually cannot be rotated or their angle adjusted after clamping. Due to the design and structural limitations of the clamp, the workpiece is fixed in one position after clamping, and the cutting angle cannot be flexibly adjusted.

[0005] Therefore, it is necessary to provide a new type of thread cutting tool with adjustable cutting angle positioning fixture to solve the above-mentioned technical problems. Utility Model Content
