Problems solved by technology

[0004] In the prior art, when drilling, the workpiece is generally held manually, or a fixed structure is used to limit the workpiece, but the first method is prone to large errors, resulting in the deviation of the drilled hole. The second method, in the The process of fixing-drilling-unfixing needs to be repeated every time drilling, the operation is more cumbersome, which affects the drilling efficiency, and when drilling, debris is prone to splash, resulting in a wide range of debris distribution and difficult cleaning

Embodiment 1

[0044] see figure 1 , a numerical control machine tool for entrainment drilling, comprising a worktable 1, a through hole 2 is dug on the worktable 1, a control box is installed on the worktable 1, a drilling assembly 3 is installed on the control box, and a drilling assembly 3 A drill bit 4 is installed in the middle part of the lower end.

[0045] see figure 2 The lower end of the drilling assembly 3 is equipped with a pneumatic hard cover, the pneumatic hard cover is located on the outside of the drill bit 4, and the pneumatic hard cover includes an inset blocking tube 6 connected to the lower end of the drilling assembly 3 and a fixed connection between the end of the internal blocking tube 6 and the The positioning soft capsule 5 between the outer ends of the drilling assembly 3, the positioning soft capsule 5 is made of elastic sealing material, and the outer fixed cylinder 61 and the inner moving cylinder 62 are made of hard materials, so that the inner block cylinder...

Embodiment 2

[0049] see Figure 9-10 , the connection between the shaping layer 81 and the pneumatic layer 82 is fixedly connected with a separation layer 12, the space surrounded by the separation layer 12 and the pneumatic layer 82 is filled with magnetic powder, and the separation layer 12 is made of an elastic sealing material, which is suitable for ferromagnetic materials. Drilling, after the air control ball 8 enters the outer fixed cylinder 61, the magnetic powder is squeezed into the shaping layer 81, and the gas enters the pneumatic expansion bar 9. At this time, the distance between the magnetic powder and the inner blocking cylinder 6 is closer, The adsorption between ferromagnetic chips is stronger, which effectively reduces the occurrence of ferromagnetic chips adhering to the workpiece and causing the impact on drilling.

[0050] The difference between this embodiment and Embodiment 1 is the internal setting of the air control ball 8, and the rest are consistent with Embodime...

Abstract

The invention discloses a numerical control machine tool for entrainment type drilling, and belongs to the field of numerical control machine tools. The numerical control machine tool for entrainment type drilling has the advantages that a pneumatic hard cover is arranged, a drill bit makes contact with a workpiece before drilling, and the workpiece is positioned, so that compared with the prior art, limiting and drilling are combined into one step, the operation complexity is reduced, the drilling efficiency is obviously improved; meanwhile, during drilling, a pneumatic suction roll enters a sunken blocking barrel along with an inner movable barrel, then internal gas is transferred into a pneumatic spreading strip, and the pneumatic spreading strip stretches to expose nylon roll hairs, so that the adhesive force of the pneumatic spreading strip to chippings is remarkably improved; on one hand, the sunken blocking barrel effectively intercepts the chippings from splashing outwards, so that the distribution range of the chippings is obviously narrowed, and cleaning difficulty is reduced; and on the other hand, the pneumatic spreading strip buffers splashing force of the chippings, and can adhere part of the chippings, so that the influence on drilling of the drill bit caused by rebounding of the chippings is effectively reduced, and the drilling effect is remarkably improved.

Description

technical field [0001] The invention relates to the field of numerical control machine tools, and more specifically relates to a numerical control machine tool for entrainment drilling. Background technique [0002] Machine tool (English name: machine tool) refers to a machine that manufactures a machine, also known as a machine tool or a machine tool, and is customarily referred to as a machine tool. Generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. There are many ways to process mechanical parts in modern machinery manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. The final machining is done by cutting on the machine tool. Machine tools play an important role in the modernization of the national economy. [0003] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Drills, reamers, reamers, taps, dies and knurling tools can ...
