Detailed implementation manners

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figures 1 - 5 shown, the present invention provides a technical solution: a tooling fixture for the blanking of injection-molded workpieces, including a mounting plate 1. A plurality of mounting seats 2 are arranged at the bottom of the mounting plate 1. The mounting seats 2 are fixedly installed at the bottom of the mounting plate 1 through fastening bolts 3. Connecting frames 4 are symmetrically arranged at both ends of the mounting seats 2. A pull ring 5 is arranged at one end of the connecting frame 4. The other end of the connecting frame 4 is fixedly connected to a movable rod 6. A spring 7 is sleeved on the outer side of the movable rod 6. One end of the movable rod 6 is connected to a wedge block 8. A mounting groove 9 is opened at the bottom of the mounting seat 2. Clamping grooves 10 are symmetrically opened inside the mounting seat 2. A clamping assembly is installed inside the mounting groove 9.

[0024] In this embodiment, through the elasticity of the spring 7, the movable rod 6 can be driven to slide inside the mounting seat 2, and then the wedge block 8 is pushed to fix the clamping assembly. When disassembling, by pulling the pull ring 5, the movable rod 6 slides outward of the mounting seat 2, and at the same time, the spring 7 is compressed and contracted, so that the wedge block 8 moves into the clamping groove 10, thereby releasing the fixing effect on the clamping assembly, reducing the disassembly and assembly difficulty of the clamping assembly, saving labor and time costs, effectively improving the overall work efficiency, and meeting the actual use requirements.

[0025] Embodiment 2: As Figures 1 - 5As shown, the clamping assembly includes a finger cylinder 13. At both ends of the top of the finger cylinder 13, two fixing brackets 11 are symmetrically arranged. The fixing brackets 11 are fixedly installed on the top of the finger cylinder 13 through two countersunk head bolts 12. At the output end of the finger cylinder 13, two clamping plates 14 are symmetrically arranged. At both ends of the top of the mounting plate 1, two aluminum profile frames 15 are symmetrically arranged. At the top of the two aluminum profile frames 15, a connecting seat 16 is fixedly installed. On one side of the aluminum profile frame 15, two stiffening rib plates 17 are arranged. The bottom of the stiffening rib plate 17 is fixedly connected to the mounting plate 1. At the bottom of the mounting plate 1, a plurality of suction cups 18 are fixedly installed. There are twenty-four suction cups 18. Among the twenty-four suction cups 18, every twelve are in a group. The two groups of suction cups 18 are both arranged on the outside of the mounting seat 2, and the two groups of suction cups 18 are symmetrically arranged with the connecting seat 16 as the center axis. There are two movable rods 6, and the wedge-shaped blocks 8 are fixedly connected to one end of the two movable rods 6. There are twelve mounting seats 2. Among the twelve mounting seats 2, every six are in a group. The two groups of mounting seats 2 are symmetrically arranged with the connecting seat 16 as the center axis.

[0026] In this embodiment, through the special design of the two wedge-shaped blocks 8, when the clamping assembly is installed, the wedge-shaped blocks 8 can be extruded to quickly retract into the card slots 10, so as to reduce the installation time required and improve the stability of the clamping assembly during use. The fixing brackets 11 can be fixedly installed on the finger cylinder 13 through the countersunk head bolts 12 to enhance the connection strength between the two. By using the clamping plates 14, the clamping area can be increased to improve the stability when clamping workpieces. Through the two aluminum profile frames 15, the stability at both ends of the connecting seat 16 can be maintained. At the same time, the connecting seat 16 can be used to connect the whole tooling fixture to the manipulator to achieve more complex and diversified blanking operations. Through the stiffening rib plates 17, the connection strength can be effectively improved and the stability during the use of the tooling clamping can be enhanced. Through the suction cups 18, the workpieces to be blanked can be adsorbed to reduce the blanking difficulty and improve the work efficiency. Through the arrangement of the two movable rods 6, the stability of the movement of the wedge-shaped blocks 8 can be improved, and at the same time, rotation misalignment can be prevented.

[0027] Working principle of this embodiment: When in use, first connect the connecting seat 16 to the manipulator to control the overall operation of the tooling fixture. Then, turn the countersunk bolt 12 to fixedly install the fixing frame 11 on the finger cylinder 13, and then push the finger cylinder 13 upward and insert it into the installation groove 9. At this time, the two fixing frames 11 squeeze the wedge blocks 8 toward both sides, causing the movable rod 6 to slide outward of the mounting seat 2. At the same time, the spring 7 is compressed and contracted, and the wedge block 8 retracts into the card slot 10. When the fixing frame 11 is completely inserted into the installation groove 9, the spring 7 quickly rebounds, driving the movable rod 6 to push the wedge block 8 to clamp and limit the fixing frame 11, thereby fixing the finger cylinder 13. Finally, when disassembling the finger cylinder 13, pull the two pull rings 5 at the same time, causing the movable rod 6 to slide outward of the mounting seat 2. At the same time, the spring 7 is squeezed and contracted, and the wedge block 8 retracts back into the card slot 10. At this time, the finger cylinder 13 falls off from the installation groove 9, thus completing the use of the injection-molded workpiece blanking tooling fixture.

[0028] The above are only the preferred embodiments of the present invention, and are not limitations on the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as the technical solution content of the present invention is not departed from, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
