Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1 to 3 The tool holder fixture shown is for limiting the length of a tool magazine in a universal machine tool. It includes a fixture base 1, a machining fixture assembly 2 fixed to the top of the fixture base 1, and a tool holder mechanism 4 mounted on the side of the machining fixture assembly 2 via a chip-proof sheet metal 3. The fixture base 1 and the machining fixture assembly 2 enclose one or more tool protection areas 5. The tool holder mechanism 4 is inverted and the tool clamping area 6 of the tool holder mechanism 4 is positioned directly opposite the tool protection area 5.

[0021] In this embodiment, the fixture base 1 includes a base plate 101, on which multiple sets of upright plates 102 are vertically fixed. The area between two adjacent upright plates 102 is a tool protection area 5. The outer surface of the upright plate 102 located at the edge is provided with anti-chip sheet metal 103. The fixture base 1 also includes an oil passage docking block 104 that is connected to the oil passages on the base plate 101 and the upright plates 102.

[0022] In this embodiment, the tool clamping mechanism 4 includes a mounting base 401, on which spring-loaded tool clamps A402 and B403 are mounted opposite each other, forming the tool clamping area 6.

[0023] In this embodiment, a blade clamp positioning key 404 is installed between the spring blade clamp A402 and the spring blade clamp B403. The blade clamp positioning key 404 is used to prevent the spring blade clamp A402 and the spring blade clamp B403 from excessively retracting and clamping.

[0024] In this embodiment, a tool positioning gas detection device 405 is provided on the mounting base 401 directly opposite the tool clamping area 6.

[0025] In this embodiment, multiple sets of the blade clamping mechanism 4 are arranged in parallel.

[0026] In this embodiment, a set of flushing nozzles 7 is provided on the anti-chip sheet metal 3 opposite to each set of the knife clamp mechanism 4.

[0027] The innovation of this application lies in providing a layered tool holder fixture that is suitable for the length limitations of tool magazines in ultra-universal machine tools. The bottom layer is a fixture base 1, the middle layer is a tool holder mechanism 4 and a tool protection zone 6 positioned opposite the tool holder mechanism 4, and the upper layer is a machining fixture assembly 2.

[0028] Specifically, the spring clips A402 and B403 are driven to move relative to each other by the drive mechanism built into the mounting base 401 (this drive mechanism is existing technology and will not be described in detail here), thereby clamping the tool. Most of the tool area is directly hidden in the tool protection area 5, which can play a good protective role. The tool clip positioning key 404 is used to prevent the spring clips A402 and B403 from excessively retracting and clamping, thus protecting the spring clips and the tool. The tool positioning air detection device 405 can detect whether the tool clip mechanism 4 is clamping the tool and feed back to the control terminal, so as to accurately realize the picking and putting of the tool.

[0029] The machining fixture assembly 2 is a conventional technical means in this field. It is conventionally configured with components such as a mounting base plate, positioning pins, guide blocks, flushing nozzles, and hydraulic clamping devices. The above-mentioned structural components can be flexibly positioned on the mounting base plate as needed.
