CONTENT OF THE UTILITY MODEL

[0003] The utility model discloses a CAPTO tool holder structure of automatic tool changing applied to numerical control machine tool, effectively improves the positioning precision of tool, the shock resistance of tool and the stability of tool, improves processing accuracy and processing efficiency.

[0004] In order to realize the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0005] A novel CAPTO tool holder structure of automatic tool changing, including tool magazine, ram, tool holder, CAPTO receiver and air-tightness detection device, the tool holder is installed on the tool magazine, the CAPTO receiver is arranged in the lower part of the ram, and the air-tightness detection device is arranged at the side part position of the CAPTO receiver.

[0006] Further, the air-tightness detection device is provided with an oil return pipe and an oil inlet pipe.

[0007] In the device, the tool magazine rotates to the specified position, and the ram is grabbed from the tool magazine to connect the tool holder with the CAPTO receiver, so as to realize the clamping and loosening functions of the tool, the CAPTO tool holder has the air-tightness detection function, detects whether the tool is clamped or loosened, the CAPTO tool holder can make the replacement and combination of the tool more flexible, the CAPTO tool holder adopts double-face positioning to ensure the service life and processing precision of the tool, the CAPTO tool holder has good shock resistance, and simultaneously has the characteristics of center water outlet, so as to more accurately cool the tool and ensure the processing precision.

[0008] The utility model discloses the beneficial effect lies in: compared with traditional knife holder, CAPTO knife holder has the following characteristics: (1) positioning accuracy is high, and CAPTO knife holder has double -sided positioning, and the life and processing accuracy of tool are ensured, (2) connection rigidity is good, and ordinary tool is easy to be damaged under high -speed state, and CAPTO knife holder can provide enough rigidity and stability to cope with the vibration and impact force produced when high -speed cutting, thereby guaranteeing processing accuracy and workpiece surface quality, (3) change is fast, and CAPTO knife holder has the characteristics of quick tool change, and this is because CAPTO knife holder adopts a simple and effective clamping mechanism, and tool can be replaced in short time, and production efficiency is improved, (4) simple structure, compared with traditional knife holder, CAPTO knife holder cancels the broach main shaft and makes the structure more simple, and simultaneously increases the air -tight detection function, and detects whether tool is clamped or relaxed.

[0015] The specific embodiment of the utility model is described below in conjunction with the drawings, so that the utility model can be better understood.

[0016] As Figures 1 to 3 The novel CAPTO knife holder structure of automatic tool changing shown in the figure, including tool magazine 1, ram 2, knife holder 3, CAPTO receiver 4 and air -tight detection device 5, knife holder 3 is installed on tool magazine 1, CAPTO receiver 4 is set in the lower part of ram 2, and air -tight detection device 5 is arranged in the side position of CAPTO receiver 4.

[0017] When the device is used, the tool magazine 1 rotates to a designated position, the ram 2 grabs the tool holder 3 from the tool magazine, and the CAPTO receiver 4 is connected to realize the clamping and loosening functions of the tool, the CAPTO tool holder has an air tightness detection function 5 to detect whether the tool is clamped or loosened, the CAPTO tool holder can make the replacement and combination of the tool more flexible, the CAPTO tool holder adopts double-sided positioning to ensure the service life and machining precision of the tool, the CAPTO tool holder has good shock resistance, and meanwhile, has the characteristics of center water outlet, so that the tool can be cooled more accurately, and the machining precision is ensured.

[0018] In the device, the air tightness detection function is added to detect whether the tool is clamped or loosened. In the CAPTO receiver 4, after oil is fed into the oil removal pipe, the CAPTO tool holder is pushed to be clamped to perform air tightness detection. The air tightness detection function is reflected in that after the tool is clamped and fitted, no air is discharged from the air hole, which indicates that the tool is clamped. Figure 5 In the middle B, the tool is in a clamped state, and in C, the tool is in a loosened state.

[0019] The above is the preferred embodiment of the utility model, and it should be pointed out that for ordinary technical personnel in the technical field, some improvements and refinements can be made without departing from the principles of the utility model, and these improvements and refinements are also regarded as the protection range of the utility model.
