Description

Technical Field

[0002] Boring machines are specially used for deep hole machining of oil cylinders, gas cylinders and hydraulic cylinders. They can also process the spindle holes, blind holes and stepped holes of machine tools. The machine tools can not only undertake various drilling and boring operations, but also roll machining. The internal or external chip removal methods are used during drilling. Boring machines are also used for boring cylinder holes and cylinder liner inner holes of internal combustion engines such as automobiles and tractors, and can also be used for precision boring of inner holes of other mechanical parts.

[0003] In the prior art, for example, Chinese patent CN214290989U discloses a boring machine, which includes a machine body, a base provided on the machine body, and electromagnetic plates rotatably connected on both sides of one end of the base in the length direction. The rotation axis of the electromagnetic plate is arranged in the vertical direction, and a limit assembly for limiting the rotation of the electromagnetic plate is provided on the base.

[0004] In the prior art, such as the above-mentioned patent, although it can prevent iron chips from splashing to a certain extent when processing the workpiece to avoid safety hazards, and at the same time, the electromagnetic plate generates magnetism when it is energized, thereby absorbing iron chips and facilitating centralized processing, but there are still the following disadvantages. Since there is no limiting structure, when drilling a workpiece, the contact area between the drill bit and the workpiece is very small. The drill bit needs to be subjected to a large friction force during cutting to keep the drill bit and the workpiece in contact, which will generate a large axial force. Under the influence of the axial force, the workpiece is prone to side shifting, thereby affecting the drilling accuracy of the workpiece. Utility Model Content
