[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0025] Please see Figures 1 to 4 The present invention provides a quick-change tool device, comprising a tool fixing seat 1, a tool pressing assembly 2, and several material suction assemblies 3. The tool fixing seat 1 includes a base plate 11 and a side plate 12. The base plate 11 and the side plate 12 are connected and surround a receiving cavity 13. Several material suction assemblies 3 are connected to the base plate 11, and the upper surface of the material suction assembly 3 protrudes from the surface of the base plate 11.

[0026] The pressure knife assembly 2 includes a pressure plate 21 and an elastic element 22. The pressure plate 21 includes a connecting part 211 and a holding part 212. The connecting part 211 is connected to the holding part 212 and is connected to the side plate 12. The holding part 212 is located above the receiving cavity 13. The elastic element 22 is connected to the holding part 212 and is located inside the receiving cavity 13.

[0027] Specifically, in this embodiment, the tool holder 1 includes a base plate 11 and a side plate 12. Preferably, the base plate 11 and the side plate 12 are integrally formed, and the cross-section of the base plate 11 and the side plate 12 is U-shaped. The accommodating cavity 13 is used to place the external tool 100. An air channel and several air holes are machined on the base plate 11, and each air hole is connected to the air channel. The suction assembly 3 is an air nozzle made of plastic. One air nozzle is placed in one air hole. The upper surface of the air nozzle protrudes from the upper surface of the base plate 1. An external vacuum generator is connected to the air channel. The connecting part 211 of the pressure plate 21 is connected to the side plate 12 by an external screw connector. Next, the elastic element 22 is fixed to the holding part 212 by a spring structure. After the external tool 100 is placed in the receiving cavity 13, the external screw connector is tightened to make the connecting part 211 and the side plate 12 firmly connected. Simultaneously, the elastic element 22 presses on the surface of the external tool 100 to pre-fix the tool 100. Then, the vacuum generator starts to work, which generates negative pressure around the air nozzle to adsorb the external tool 100, so that the tool is fixed in the tool fixing seat 1. The upper surface of the air nozzle protrudes from the upper surface structure of the base plate 11, so that the air nozzle and the tool are in full contact, improving the adsorption connection force.

[0028] By setting several suction components 3 in the tool holder 1, the upper surface of the suction components 3 protrudes from the upper surface of the base plate 11. The pressure component 2 includes a connector 21 and an elastic component 22. The connector 21 includes a connecting part 211 and a holding part 212. The elastic component 22 is located in the holding part 212. The elastic component 22 pre-fixes the external tool 100. The suction components 3 vacuum adsorb the external tool 100, thereby improving the firmness of the external tool 100 fixed in the tool holder 1 and meeting the production requirements.

[0029] The connecting part 211 and the pressing part 212 are integrally formed, avoiding the tolerance caused by assembly connection and improving production accuracy.

[0030] The pressing part 212 is provided with a plurality of grooves 2121, the opening of the grooves 2121 is oriented toward the receiving cavity 13, and an elastic member 22 is provided in one of the grooves 2121.

[0031] The three adjacent grooves 2121 are arranged in a triangular shape, that is, the three adjacent elastic elements 22 are arranged in a triangular shape, which provides stability for holding the external tool 100.

[0032] The base plate 11 is cuboid in shape, the side plates 12 are located on opposite sides of the base plate 11, and the accommodating cavity 13 is arranged along the width direction of the base plate 11 to facilitate the side insertion and removal of external tools 100.

[0033] The tool holder 1 is provided with a plurality of side grooves 121. The side grooves 121 are provided on the side plate 12 and are oriented toward the receiving cavity 13. The side grooves 121 reduce the contact surface between the side plate 12 and the external tool 100, thereby reducing the frictional resistance when the external tool 100 is pushed into the receiving cavity 13.

[0034] The thickness of the connecting part 211 is greater than the thickness of the pressing part 212, which increases the elastic range of the elastic member 22, that is, increases the elastic force, and provides the elastic member 22 with the elastic force to press the external tool.

[0035] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
