Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a tooling fixture with auxiliary positioning function. Background Technology

[0002] In machining and assembly processes, tooling fixtures are key equipment for achieving accurate workpiece positioning and stable clamping. As the manufacturing industry moves towards higher precision and efficiency, traditional tooling fixtures are gradually revealing their shortcomings in terms of positioning accuracy, ease of operation, and applicability. Especially in the machining of complex workpieces and in multi-variety, small-batch production, traditional fixtures struggle to meet the demands for rapid changeovers and precise positioning. Therefore, a tooling fixture with auxiliary positioning functions is needed.

[0003] A search revealed Chinese Patent Publication No. CN219403361U, which discloses a universal tooling fixture with positioning and clamping functions. The fixture includes an industrial robot and multiple sets of universal tooling. Each set of tooling includes a clamping base plate fixed to the industrial robot's worktable and a traveling tooling plate detachably connected to the clamping base plate. Due to the connecting components used to connect the clamping base plate and the traveling tooling plate, a clamping assembly is detachably connected to the traveling tooling plate. A zero-point positioning rivet is provided on one side of the traveling tooling plate, and the zero-point positioning rivet is adapted to the industrial robot's gripper. The clamping base plate and connecting components in each set of universal tooling are of the same specifications. This invention allows for quick product replacement on a five-axis machine tool without multiple manual clamping interventions, and is suitable for mixed-line processing of multiple product varieties on automated production lines.

[0004] In the aforementioned utility model, by disassembling the accompanying tooling plate on the clamping base plate and positioning the zero-point positioning rivet on the accompanying tooling plate with the matching elements of the industrial robot's gripper, multiple manual interventions are not required for clamping. This method is applicable to mixed-line processing of multiple products on automated lines. However, in actual use, there are still problems such as low positioning accuracy and poor operating efficiency. Utility Model Content

Specifically, by driving the sliding table 901 to slide on the upper surface of the base 1, the sliding table 901 is positioned. The sliding table 901 is limited by sliding on the outer wall of the slide rail 902. The slide rail 902 fixes the base 1.

[0029] Reference Figure 5A drive cylinder 10 is fixedly connected inside the sliding table 901, and a connecting block 11 is fixedly connected to the output end of the drive cylinder 10.

Specifically, the laser emitter 19 installed inside the base 1 can achieve precise positioning. The laser emitter 19 and receiver 20 are both red lasers, and the receiver 20 works in conjunction with the laser emitter 19 to achieve precise positioning.

[0031] Working principle: When the fixture is needed, it is first positioned to the required position. The sliding table 901 is moved to slide on the outer wall of the slide rail 902. The laser emitter 19 is activated. With the cooperation of the receiver 20, the sliding table 901 is moved to the appropriate position. At this time, the fixing plate 7 is moved to slide on the outer wall of the limiting block 6. Then, the spring 5 can move the sliding plate 4 to slide inside the positioning block 2. At the same time, the positioning pin 3 is moved to slide inside the base 1, thereby achieving the function of limiting the positioning block 2. Then, the positioning block 2 and the base 1 are connected and fixed by rotating the bolt 8, achieving the effect of precise positioning of the fixture. The machine to be processed is placed on the upper surface of the sliding table 901. By starting the drive cylinder 10, the connecting block 11 can slide on the outer wall of the limiting plate 17. While the limiting plate 17 is sliding, the rotating plate 13 can rotate on the outer wall of the rotating shaft 12. Then, by rotating the rotating plate 13 on the outer wall of the rotating shaft 14, the sliding block 15 can slide on the outer wall of the limiting strip 16, which in turn drives the clamping arm 18 to slide inside the sliding table 901. This achieves the effect of clamping and fixing the machine with the clamping arm 18, improving the stability of the workpiece clamping. This fixture can not only achieve the effect of stable clamping of the workpiece for precise positioning, but also enhance the adaptability of the fixture, enabling it to meet the needs of multi-variety small-batch production.
