Problems solved by technology
However, in the long-term processing process, the screw of the screw mechanism will gradually heat up and cause the temperature to rise, which will affect the processing precision of the machine tool
The traditional way to solve the heat generation of the screw is: to cool the screw through the shower coolant or to increase the lubricating oil to reduce the friction to solve the heat problem, but the effect of these two methods is not good, and the operation is troublesome

The invention relates to an automatic cooling lead screw mechanism for a five-axis linked machining center. The automatic cooling lead screw mechanism comprises a bearing block, a motor fixing seat, a screw, a motor, a screw internal-cooling fixing seat and a cooling oil pipe, wherein the head end of the screw is arranged on the motor fixing seat; the tail end of the screw penetrates through the bearing block; the motor is arranged on the motor fixing seat and is coupled with the head end of the screw; the screw is provided with a cooling hole from the tail end to the head end; the cooling oil pipe is inserted into a cooling hole; a clearance is formed between the cooling oil pipe and the inner wall of the cooling hole; the screw internal-cooling fixing seat is fixed on the bearing block and surrounds the tail end of the screw; and an oil inlet channel communicating with the cooling oil pipe and an oil outlet channel communicating with the cooling hole are arranged in the screw internal-cooling fixing seat. According to the automatic cooling lead screw mechanism for the five-axis linked machining center, disclosed by the invention, the cooling oil pipe is arranged in the screw, and the oil inlet channel and the oil outlet channel which are used for allowing the cooling oil to flow in and out are arranged on the screw internal-cooling fixing seat, so that the heat in the screw can be taken away, and automatic cooling of the lead screw mechanism is realized.
Description
technical field [0001] The invention relates to the field of drive equipment, in particular to an automatic cooling lead screw mechanism for a five-axis linkage machining center. Background technique [0002] The five-axis linkage machining center is a kind of CNC machine tool, which is generally equipped with a base, a workbench and a processing department. On the five-axis linkage machining center, in order to move the parts to be processed to the bottom of the processing part, a screw mechanism is often used to drive the table to move. However, in the long-term processing process, the screw rod of the screw mechanism will gradually heat up and cause the temperature to rise, which will affect the processing precision of the machine tool. The traditional way to solve the heating problem of the screw is: to cool the screw through the shower coolant or to increase the lubricating oil to reduce the friction to solve the heating problem, but the effect of these two methods is ...
