Description

Technical Field

[0001] The utility model relates to the technical field of welding, and particularly relates to a welding tooling for compensating for the welding deformation of a flange and a head. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate the components in a mixture of liquid and solid particles or liquid and liquid. The magnitude of the centrifugal force is determined by the rotational speed, the radius of rotation, and the mass of the substance. A centrifuge and a method for controlling the centrifuge include a rotor having a rotating shaft, at least one container for a blood sample container, a controller device for controlling the rotational speed of the rotor, at least one optical transmitter for transmitting an optical signal, at least one optical receiver for recording the amplitude of the optical signal, etc. Among them, the centrifuge flip cover body and the flip cover body flange need to be fixed together by welding.

[0003] For example, for a tooling for welding and assembling a head and a flange with the application number CN201711221209.0 and the authorization announcement date of September 17, 2019, a pressure plate and a backing plate are sleeved on the upper part of the main shaft, and the pressure plate is located above the backing plate. The ends of each mounting rod on the circumference of the pressure plate are respectively provided with an offset adjustment bolt, and the top of each offset variable adjustment bolt corresponds to the head support surface at the edge of the upper surface of the circumference of the backing plate. The lift adjustment bolt is installed on the backing plate. There are a plurality of radially extending support rods on the outer circumferential surface of the backing plate; the edge of the upper surface of the support rod is an arc surface that fits the inner arc surface of the head. There are mounting holes for the lift adjustment bolts on each support rod. The present invention can realize the pre-welding assembly of ellipsoidal opening heads with various thicknesses and various diameters and flanges, and the assembly quality meets the requirements of the welding process.

[0004] It is concluded from long-term production practice that when the centrifuge flip cover body and the flip cover body flange are welded, under the condition that other conditions are the same, the flange plane will generate a 2-mm welding deformation. This deformation amount will deteriorate the overall airtightness of the centrifuge. To eliminate this deformation amount, the previous method was to increase the flange thickness to reserve the machining allowance after deformation, and then machine it after welding deformation. These two steps increase the material cost and the labor cost of the process. Therefore, it is urgent to design a welding tooling for compensating for the welding deformation of the flange and the head to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a welding tooling for compensating for the welding deformation of a flange and a head to solve the above deficiencies in the prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A welding tooling for compensating the welding deformation between a flange and a head, comprising a fixed seat. A flange member is provided on the top of the fixed seat. A flip body is arranged inside the flange member. A plurality of fixing components are provided on the outer wall of the top of the fixed seat. The fixing component includes a clamping seat. A plugging hole is formed on one side of the outer wall of the top of the clamping seat. A limit bolt is slidably plugged inside the plugging hole, and the bottom end of the limit bolt is threadedly connected to the fixed seat.

[0008] Further, the fixed seat includes an installation cylinder. An installation groove is formed at the center of the outer wall of the top of the installation cylinder. The flange member is clamped inside the installation groove.

[0009] Further, a plurality of threaded holes are formed at the edge of the outer wall of the top of the installation cylinder. The bottom end of the limit bolt is threadedly connected inside the threaded hole.

[0010] In the above technical solution, for a welding tooling for compensating the welding deformation between a flange and a head provided by the present utility model, the beneficial effects are as follows:

[0011] (1) By providing the fixed seat and the fixing components, the welding tooling composed of the fixed seat and the fixing components can incline the plane of the flange member by 2 mm during welding. During subsequent welding, the original welding deformation can be eliminated through this welding tooling, greatly saving the material cost and the labor cost of the process.
