Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0029] The embodiment of the four-station tool rest for the pre-cooled CNC lathe is as follows:
[0030] see Figure 1-5 , a pre-cooled four-station tool post for CNC lathes, including a base 1, a rotary table 2, a servo motor 3, a connecting shaft 4 and an oil injection device 5.
[0031] Wherein, the rotary table 2 includes a positioning hole 21 , a vertical fixing bolt 22 , a horizontal fixing bolt 23 , a backing blade 24 , and a turning tool 25 .

The invention provides a pre-cooled four-station tool holder for a numerically controlled lathe, which relates to the technical field of numerical control manufacturing. The connecting shaft is connected to the top of the base in rotation, the servo motor is fixedly connected to the periphery of the base, the oil injection device is fixedly connected to the inside of the base, a positioning hole is opened in the inside of the rotary table, and the internal positioning of the rotary table The top of the hole is rotatably connected with a vertical fixing bolt, and the right side of the positioning hole inside the turntable is rotatably connected with a horizontal fixing bolt. The pre-cooled four-station tool holder for CNC lathes positions the tool in the up, down, left and right directions, which improves the stability of the tool installation, and can pre-cool the tool to be used after the tool change is completed. The impact on cutting quality and service life of the turning tool due to excessive tool temperature is avoided.
Description
technical field [0001] The invention relates to the technical field of numerical control manufacturing, in particular to a pre-cooled four-station tool holder for a numerical control lathe. Background technique [0002] The four-station tool holder is a mobile tool fixing device installed on the CNC machine tool, which can fix and place four tools at the same time, and through the cooperation of the servo motor and system programming, the four tools can be rotated and switched during CNC cutting, realizing The automatic production of CNC machine tools improves the cutting efficiency. [0003] However, the general four-station tool post only has vertical fastening bolts for the fixing device of the tool, and the tool is squeezed up and down to complete the positioning. However, because a pad blade needs to be placed under the general tool, the stability of the tool installation is reduced. , when the tool is subject to a large cutting stress, it is easy to shift in the horiz...
