Abstract

The invention discloses a horizontal double-station drilling and tapping machine tool. The horizontal double-station drilling and tapping machine tool comprises a machine tool body (1), a clamp (6), acylinder surface drilling mechanism (2), a cylinder surface tapping mechanism (3), a hydraulic unit (4) and a cooling unit (5), wherein the cylinder surface drilling mechanism (2) and the cylinder surface tapping mechanism (3) are symmetrically arranged on the machine tool body (1); the cylinder surface drilling mechanism (2) comprises a drilling driving motor (201) and a drilling device (202); the cylinder surface tapping mechanism (3) comprises a tapping driving motor (301) and a tapping device (302); the hydraulic unit (4) is arranged on one side of the machine tool body (1) and comprisesa servo motor (401) and hydraulic oil cylinders (402); the hydraulic oil cylinders (402) are respectively in hydraulic connection with the clamp (6), the cylinder surface drilling mechanism (2) and the cylinder surface tapping mechanism (3); and the cooling unit (5) is arranged on the other side of the machine tool body (1). According to the horizontal double-station drilling and tapping machine tool, the drilling and tapping of a workpiece are simultaneously realized, the vibration in the machining processes can be reduced, and the machining precision and efficiency are high.

Description

technical field [0001] The invention belongs to the field of drilling machine tools, and more specifically relates to a horizontal double-station drilling and tapping machine tool. Background technique [0002] A drilling machine is a machine tool that mainly uses a drill bit to process holes on a workpiece. Usually, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The drilling machine has a simple structure and relatively low machining accuracy. It can drill through holes and blind holes, replace special tools, and can be expanded, countersinked, reamed, or tapped. [0003] The existing drilling and tapping machine tools are generally vertical. The drilling and tapping machine tools with this structure take up more space, and the assembly of the whole equipment is more troublesome. The most important thing is that the vertical center of gravity is high during processing. , prone to vibration, so the machining...

Problems solved by technology

[0003] The existing drilling and tapping machine tools are generally vertical. The drilling and tapping machine tools with this structure take up more space, and the assembly of the whole equipment is more troublesome. The most important thing is that the vertical center of gravity is high during processing. , prone to vibration, so the machining accuracy is not high

In addition, the power head will generate a very high temperature during high-speed operation, so cooling water is generally used to cool down the temperature mechanically. The existing power head generally uses the nozzle to spray water against the position of the tool to achieve the effect of cooling , this way of cooling can only reduce the temperature at the knife edge position, the temperature of the main shaft inside the power head is still very high, so long-term processing will cause the temperature of the main shaft to rise, which will affect the performance of the power head, and finally reduce the processing accuracy, even Damage to the spindle, resulting in equipment failure
