Embodiment 1

[0028] A method for positioning and assembling ring parts, such as figure 1 As shown, for the positioning installation of ring parts, the positioning assembly method includes the following steps:

[0029] Step 1. Positioning the assembly fixture: assemble the fixture at the connection position of the part I1 and the part II2; Step 2. Axial reference positioning: Position the two axial faces of the single piece 1a and the lower single piece 1b of the part Ⅰ1; Step 3. Radial reference positioning: Radial positioning of the part I1 of the parts with precise inner circle size and roundness; step four, reserved interference parts: such as figure 2 As shown, reserve space for the interference of screws and lugs on part II2; step five, point-to-point assembly: use a three-point fixed plane method to fix; step six, remove the fixture and check the parts.

[0030] Such as image 3 As shown, the fixture includes a fixture upper cover 7 ( Figure 4 ) And fixture lower cover 8 ( Figure 5 ), ...

Embodiment 2

[0033] Place the lower cover 8 of the fixture on the platform symmetrically, put the part Ⅰ 1 into the positioning slot 3, loosen the part Ⅱ 2 and the part Ⅰ 1 with screws, cover the upper cover of the fixture on the parts Ⅰ1 and Ⅱ 2, and pass the screws with 3 screws Hole Ⅰ 4a, screw hole Ⅱ 4b and screw hole Ⅲ 4c are connected to realize a three-point fixed plane, so that the upper cover 7 and lower cover 8 of the fixture are tightly matched with the positioning surface of part Ⅰ1, and the connecting screws of part Ⅰ1 and part Ⅱ2 are aligned according to the required torque Point connection, the setting of holes I5 and II5b avoid the interference of the screws on the part II2; the setting of the lug interference groove I6a, the lug interference groove II6b and the lug interference groove III6c avoid the interference of the lugs on the part II2; cover the fixture 7 Loosen the connecting screw with the lower cover 8 of the fixture, remove the upper cover 7 of the fixture, take ou...

Abstract

The invention discloses a locating assembly method of a ring part. The locating assembly method is used for location and installation of the ring part, and comprises the following steps of assembly and location of a fixture, axial reference location, radial reference location, involved part reservation, point-to-point assembly, fixture removal and part inspection. The locating assembly method hasthe advantages of high assembly accuracy, simple operation, convenience, low cost and good on-site using effect. The problems of unqualified assembly, high rework rate and complicated regulating process of the ring part can be solved.

Description

Technical field [0001] The invention relates to the field of mechanical manufacturing and ring parts assembly, in particular to a positioning assembly method for ring parts. Background technique [0002] Assembling ring-shaped parts is a relatively large-scale part in the current production. This type of part is a plurality of ring segments connected in the radial direction, without axial positioning. During the assembly process, there are many factors that affect the quality of the part after assembly. The rework rate is high, and the factors affecting the assembly cannot be confirmed during the rework process. Workers are required to debug repeatedly. The workload is large and the process is cumbersome, which seriously affects the delivery of parts. Therefore, a fast and convenient assembly method is imminent. Summary of the invention [0003] The purpose of the present invention is to address the shortcomings of the prior art, alleviate the problems of large workload and cumber...
