Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to an air blowing mechanism. Background Art

[0002] At present, most CNC machining centers will have a large amount of aluminum chips flying during the machining process. The aluminum chips will remain on the tooling reference positioning surface, resulting in improper placement of parts, positioning failure, and scrapping of processed products. Every time an employee processes a part, before moving on to the next part, the tooling reference positioning surface needs to be purged and checked with a small air gun.

[0003] The traditional method of blowing with an air gun not only wastes labor time and reduces employee efficiency, but also requires manual work at each point, which is time-consuming. In addition, the blowing is not clean. During the manual hand-held air gun blowing process, it is easy to cause aluminum chips to be blown onto the working positioning surface of the adjacent support block, resulting in the need for repeated blowing.

[0007] Two adjacent side surfaces of the blowing block are respectively against two side surfaces of the right-angle notch;

[0008] An air pipe joint for connecting an air pipe is installed on the air blowing block, and the air pipe joint is connected to the strip-shaped air outlet through a guide channel.

[0009] The utility model optimizes the structure of the positioning block and adds an air blowing component, so as to facilitate the blowing away of aluminum chips.

[0010] Further preferably, a mounting hole for passing a mounting bolt is formed on the positioning block, and the mounting hole is vertically arranged.

[0011] Further preferably, the right-angle notch is located at the rear end of the positioning block, and the axial direction of the trachea joint is the left-right direction.

[0012] Further preferably, the blowing block is connected to one end of the connecting rod by a bolt;

[0013] The positioning block is connected to the other end of the connecting rod through a bolt;

[0014] The air blowing block and the positioning block are both provided with threaded holes for threaded connection bolts.

[0015] The utility model facilitates the connection between the air blowing block and the positioning block through the connecting rod.

[0016] Further preferably, the longitudinal width of the strip-shaped air outlet is 0.1-0.2 mm.

[0017] Further preferably, the longitudinal distance between the bottom of the strip-shaped air outlet and the positioning surface is 0.5 mm-1 mm.

[0018] This makes it easier to ensure that the gas acts on the positioning surface.

[0019] Further preferably, the positioning blocks are arranged in one-to-one correspondence with the air pipes, at least three of the air pipes are connected to a main air pipe, a valve is installed on the main air pipe, and the main air pipe is connected to an air supply mechanism.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] The utility model integrates a blowing component on the positioning block, which not only saves the operator's time, but also ensures that the positioning surface of each positioning block can be blown clean without causing secondary pollution. Multiple positioning blocks can be blown at the same time, which is different from employees using air guns to clean one point at a time, with higher efficiency and better stability.
