Example Embodiment

[0028] Example 1

[0029] See Figure 1~3 In the embodiment of the present invention, the drive assembly includes a first magnetic block group 23 and a second magnetic block group 26. The first magnetic block group 23 is composed of two electromagnetic blocks respectively fixed to the chute 31 and the tool holder 51. The end of the tool holder 51 close to the center of the turntable 3 is elastically connected to the sliding groove 31 through the first elastic member 22; the end of the tool holder 51 away from the center of the turntable 3 is symmetrically provided with mounting grooves 512 on both sides, and a sliding card in the mounting groove 512 A locking block 24 is provided. The locking block 24 is elastically connected to the mounting groove 512 through a second elastic member 25. The sliding groove 31 is provided with a locking block 311 that is matched with the locking block 24; the second magnetic block group 26 consists of two The second magnetic block set 26 and the f...

Example Embodiment

[0033] Example 2

[0034] See Figure 4~6 In the embodiment of the present invention, the drive assembly includes a telescopic device 9, the fixed end of the telescopic device 9 is fixed in the chute 31, the movable end of the telescopic device 9 is connected to the tool holder 51, and the telescopic device 9 is electrically connected to the trigger assembly.

[0035] In this embodiment, when the sensor 6 rotates to a position that matches the triggering member 7, the telescopic device 9 drives the tool holder 51 to move outwards, and then drives the tool head 52 to extend out of the chute 31. When the sensor 6 rotates to and triggers When the piece 7 is in the matched position, the extension device 9 drives the tool holder 51 to move inward, and then drives the tool head 52 to retract into the chute 31.

[0036] The specific structure of the telescopic device 9 is not limited, and may be an electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod. In this e...

Abstract

The invention discloses an automatic extension cutter frame device for a numerical control machine, relates to the field of numerical control, and mainly solves the problem of lower cutter change efficiency in an existing numerical control machine. The device comprises a mounting base; the mounting base is provided with a groove; a rotating disc is arranged in the groove, and is rotationally connected into the groove through a rotating shaft; a motor for driving the rotating disc to rotate is mounted in the mounting base; at least two chutes are formed in the rotating disc at equal intervals in the peripheral direction; cutters capable of moving back and forth in the length directions are arranged in the chutes; driving modules for driving the cutters to slide back and forth are arranged in the chutes; and the driving modules are electrically connected with trigger modules. The cutters are slidingly arranged on the rotating disc; through cooperation between the driving modules and thetrigger modules, the cutter change can be realized through rotation of the rotating disc without needing excessive manual operations, so that the cutter change efficiency can be effectively improved,and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of numerical control, in particular to an automatic retractable tool rest device for numerical control machines. Background technique [0002] Numerical control technology is the base for the manufacturing industry to realize automation, flexibility, and integrated production. It is the core of modern manufacturing technology and an essential means to improve the product quality and labor productivity of the manufacturing industry. Machine tool builders are constantly advancing new products to help toolmakers and grinding shops increase productivity and reduce costs. In order to improve the utilization rate of machine tools and reduce labor costs, automation has been paid more and more attention. At the same time, through the development of software, the functions of the machine tool can be expanded, and the production schedule can be economically arranged under the condition of small production batches and short del...
