Problems solved by technology

This method can be adopted for occasions that do not require high coaxiality, but it cannot meet the requirements for occasions that require high coaxiality, and it needs to be measured repeatedly, which is time-consuming and laborious
Or use the method of making simple tooling to determine the coaxiality, but the coaxiality guarantee of these toolings is still not high, and when the diameter of the head changes with the tolerance, these toolings lose their ef

Embodiment Construction

[0021] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0022] like Figure 1~4 As shown, the head 1 of this embodiment includes a centering device 2, a support plate 3 fixed inside the head 1 and a shaft sleeve 4 to be coaxially fixed with the head 1, and the centering device 2 includes three sets of positioning mechanisms 21. Positioning sleeve 22, sliding sleeve 23 and central tube 24; each set of positioning mechanism 21 includes a first connecting piece 211, a second connecting piece 212, a third connecting piece 213, a connecting rod 214 and an extension claw 215; the first connection 211 is fixed on the central tube 24, the second connecting piece 212 is fixed o...

Abstract

The invention discloses a flexible coaxiality centering device and a seal with the same. First connectors are fixed on a center pipe, second connectors are fixed on a slide sleeve, third connectors are fixed on connecting rods, and the first connectors, the second connectors and the third connectors are arranged on three peaks of a triangle respectively. One end of each elongated claw is hinged to each first connector, and the other end is hung in the air. One ends of the connecting rods are hinged to the second connectors and the other ends are hinged to the elongated claws through the third connectors. A positioning sleeve is connected with the bottom of the slide sleeve, the center pipe is sleeved with the slide sleeve, and included angles of adjacent positioning mechanisms are the same along the circumference of the center pipe. The flexible coaxiality centering device can meet the requirement for higher coaxiality. When the diameter of the seal changes as tolerance, the flexible coaxiliaty centering device also changes so as to ensure the requirement for the coaxiality, and flexible centering is embodied.

Description

technical field [0001] The invention relates to an auxiliary tool for a head, in particular to a coaxiality flexible centering device and a head using the device. Background technique [0002] At present, heads are often used in the chemical industry and other industries, and some required parts or components need to be welded on the axis of the head, and then assembled. These parts or components welded on the axis of the head are often required to be welded on the positive axis of the head, and the requirements for coaxiality are very high; otherwise, it will not only affect the welding quality of the product, but also seriously affect the final product. assembly. Taking a certain product as an example, it is required to weld a part in the direction of the head axis, and the concentricity between the part and the head axis needs to be controlled within the range of 0.25, which is very strict. If the coaxiality requirements cannot be guaranteed, multiple adjustments and sh...
