DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Example 1: Please refer to Figure 1 - Figure 5 The present invention provides a technical solution: a cutting device for machining gears of aircraft parts, specifically comprising: A machine base 1, with an arc bar 2 fixedly mounted on the top of the machine base 1, and spacing adjustment devices 3 movably mounted on both sides of the top of the arc bar 2, the spacing adjustment devices 3 are used to adjust the lateral spacing; The distance adjustment device 3 includes a pressure plate 31, a vertical piece 32 is fixedly installed on the top of the pressure plate 31, and the vertical piece 32 can slide in the horizontal direction along the inner cavity of the pressure plate 31. A groove corresponding to the pressure block 33 is opened in the inner cavity of the vertical piece 32. The vertical piece 32 is slidably installed with the pressure block 33. A vertical rod 36 is movably installed in the middle of the top of the pressure block 33. A sleeve pad 37 is fixedly sleeved on the outer surface of the vertical rod 36. A seat 35 and a middle piece 34 are movably installed in the middle of the top of the arc bar 2. The middle piece 34 is located behind the seat 35. The seat 35 protects the sliding Too much sliding and falling, glue is coated between the middle piece 34 and the arc strip 2, and the holder 35 is embedded and installed in the inner cavity of the middle piece 34. The holder 35 prevents the middle piece 34 from sliding too much and falling. The middle piece 34 and the holder 35 cooperate to facilitate auxiliary clamping of the middle plate 67. The pressure plate 31 is symmetrically designed with the center line of the middle piece 34 as a reference. A sliding groove corresponding to the pressure plate 31 is arranged at the bottom of the vertical piece 32. The pressure plate 31 is made of stainless steel, and a notch is arranged on the side of the vertical piece 32. The vertical directions of the vertical piece 32 and the pressure plate 31 are opposite.

[0017] Since the lengths of workpieces are different, when the length needs to be adjusted, a slide rail corresponding to the pressure plate 31 is set at the bottom of the vertical member 32, and the vertical member 32 can slide horizontally along the inner cavity of the pressure plate 31. A groove corresponding to the pressure block 33 is opened in the inner cavity of the vertical member 32. The slide rail at the bottom end of the pressure block 33 can slide in the front and back directions along the inner cavity of the vertical member 32, and the pressure block 33 drives the vertical rod 36 to move synchronously, thereby ensuring that the equipment has the problem of quickly adjusting the length and distance, and achieving the purpose of processing.

The connecting plate on the sleeve pad 37 is pressed downward and contacts with the pressure block 33, and the connecting plate on the sleeve pad 37 is deformed. The front and rear sides of the connecting plate on the sleeve pad 37 have a tendency to press downward, and the mounting strip on the sleeve pad 37 moves along the top of the pressure block 33, and the connecting plate on the sleeve pad 37 is driven from the inside to the outside, thereby forming an extended deformation on the upper connecting plate of the sleeve pad 37, and the expanded downward pressure will strengthen the stability of the bottom, thereby causing the sleeve pad 37 to gradually improve the stability performance of the vertical rod 36, and the vertical rod 36 slowly slides from the inner cavity of the connecting plate at the top of the sleeve pad 37, and the sleeve pad 37 is sleeved on the outside of the vertical rod 36.

When the plate seat 471 is pressed downward, the plate seat 471 is sleeved on the outer side of 472, and the plate seat 471 slides down along the outer surface of the middle side piece 472, and the middle side piece 472 forms a downward displacement and extrusion trend. The top of the middle side piece 472 opens outward, and a bottom arc strip 473 is fixedly installed at the bottom end of the middle side piece 472. The bottom of the middle side piece 472 is tightened, and the two middle side pieces 472 in each group move closer to the middle, and the middle side piece 472 squeezes the bottom arc strip 473.

The middle side parts 472 are evenly distributed with reference to the center line of the plate seat 471, and the middle side parts 472 are made of stainless steel.

[0021] As the cutting waste gradually flies out and gradually pollutes the inside of the equipment, the vertical rod 36 penetrates the sleeve pad 37 and extends to the inside of the plate seat 471. The synchronous waste moves towards the plate seat 471 under the action of cutting. The upper surface of the plate seat 471 is squeezed by the accumulated dust. When the plate seat 471 is pressed downward, the plate seat 471 is sleeved on the outer side of 472, and the plate seat 471 slides down along the outer surface of the middle side member 472. When the plate seat 471 is pressed downward, the plate seat 471 slides down along the outer surface of the middle side member 472, and the plate seat 471 forms a downward displacement and extrusion trend. The top of the middle side member 472 opens outward, and the bottom of the middle side member 472 is tightened. The side piece 472 expands outward, and the middle side piece 472 squeezes the bottom arc strip 473. The middle side piece 472 itself has an inclined surface. The middle side piece 472 is limited by the groove of the plate seat 471 to deform the inclined surface, and the middle side piece 472 moves in the direction close to 474. The pulling piece 474 moves under the influence of the middle side piece 472, and the pulling piece 474 slides along the outer surface of the thin support strip 475. The pulling piece 474 and the thin support strip 475 move closer to each other, and the top of the middle side piece 472 is gradually stretched open.
