BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0015] As shown in the accompanying drawings, this embodiment provides a clamping type contour positioning tool for processing a shell, including a fixture body 1, a contour groove 2 corresponding to the shape of a large workpiece 8 is provided in the middle of one side of the fixture body 1, and the contour groove 2 is used to contour and position the workpiece 8 to limit the angular positioning of the workpiece 8.

[0016] Three lever cylinders 3 are arranged on the fixture body 1 at the periphery of the profiling groove 2 for jointly pressing the workpiece 8. The three lever cylinders 3 form a triangular distribution outside the profiling groove 2. The lever cylinders 3 jointly press the workpiece 8 to ensure that the workpiece 8 has sufficient fixed clamping force.

[0017] Support blocks 4 are provided at both ends of the bottom of the corresponding profiling groove 2 on the fixture body 1. A plurality of positioning blocks 7 with air outlets 6 are provided on the support blocks 4 and are connected to the pressure switch outside the equipment. The change of the air source pressure is used to detect whether each positioning block 7 is in contact with the processing surface of the workpiece 8 (the green light of the pressure switch can be visually observed to be all on, and a red light will be displayed if the positioning point is not in contact, and the machine tool alarm will be issued). This verifies the inaccurate positioning caused by the residual aluminum chips on the positioning surface of the tooling, which greatly ensures the positioning accuracy of the workpiece 8.

[0018] Linear cylinders 5 are respectively arranged on the fixture body 1 outside the profiling groove 2 in the vertical and horizontal directions for pre-positioning the workpiece 8, thereby reducing the efficiency loss and positioning inconsistency caused by the inconvenience of manual operation.

[0019] The installation operation of the tooling is simple. When installing the workpiece 8, the operator only needs to hold the workpiece 8 with both hands and install the workpiece 8 as a whole into the tooling profiling groove 2. After manual installation, the action sequence of the tooling is the side push of the linear cylinder 5 in the X direction, the side push of the linear cylinder 5 in the Y direction, the air source contact detection, the lever cylinder 3 is pressed together, and the processing starts.

[0020] It can be understood that the above specific description of the utility model is only used to illustrate the utility model and is not limited to the technical solution described in the implementation mode of the utility model. Ordinary technicians in the field should understand that the utility model can still be modified or replaced by equivalents to achieve the same technical effect; as long as the use requirements are met, they are within the protection scope of the utility model.
