Detailed Description
The following description is made in conjunction with the embodiments of the present invention, and it should be noted that the present invention is not limited to the following embodiments, and all the same changes made on the basis of the technical solution of the present invention fall into the protection scope of the present invention.
As shown in the following figures 1-3, the butt joint device for the two-stage engine combustion chamber for solving the problem of assembling the two-stage engine combustion chamber with the diameter of less than 600mm comprises a supporting platform 1, an adjusting block 2, a hoop component 3, a butt joint pressing device component 4 and a linear guide rail 5.
The height of the supporting platform 1 is 820mm, and two groups of holes are respectively drilled on two supporting legs on the left side of the supporting platform 1 in parallel and are used for connecting two groups of same devices; the bottom of the supporting platform 1 is provided with an adjusting block 2 which is connected with the supporting legs of the supporting platform through threads and used for adjusting the levelness of the supporting platform 1; two linear guide rails 5 are arranged above the supporting platform 1 and used for adjusting the position of the hoop component 3. The clamp component 3 is connected with a sliding block on the linear guide rail 5 through a bolt, the clamp component 3 comprises an upper clamp and a lower clamp, and the upper clamp and the lower clamp are used for clamping a combustion chamber of an engine and are fixed through bolts and nuts. The butt joint pressing device assembly 4 comprises a rubber mat, a butt joint top plate, a bearing seat assembly, a guide rod seat, a lead screw and a hand wheel, the butt joint pressing device assembly 4 is installed on the right side above the supporting platform 1 through bolts, feeding of the butt joint top plate in the pressing device is achieved through rotation of the hand wheel, and a pressing process of the two-stage engine combustion chamber after concentricity is completed.
