Problems solved by technology
At present, welding is often used to connect the support arm and the stern hub. Due to the large structure of the support arm and poor heat dissipation, the stern tube is easily deformed during the welding process. In order to ensure that the installed stern shaft and stern shaft The concentricity between the tubes often needs to be bored on the stern tube. Due to the large size of the stern tube and the support arm, the boring is difficult, time-consuming and laborious, and the processing efficiency is low. The labor intensity is high. The cost is high and cannot well meet the production requirements of the enterprise

Embodiment Construction
[0020] Combine now figure 1 The present invention is described, and the present invention comprises the following steps:
[0021] a. Machining the welding slit 2 on the support arm 1, the support arm 1 is divided into the upper support arm 11 and the lower support arm 12, and processing the welding slit 2 on the lower end surface of the lower support arm 12;
[0022] b. Weld the two lower support arms 12 on the stern hub 3 at a certain angle. According to the welding position of the root of the lower support arm 12, the center line and the horizontal line are drawn, and the center line is also drawn on the side of the stern hub 3, and the center line is extended to the said stern hub 3 connected. At the root of the lower support arm 12, a center line is drawn on the leading edge and the trailing edge of the root of the lower support arm 12, and the lower support arm 12 is welded to the stern hub 3 according to the center line drawn above;
[0023] c. welding the stern sh...

The invention discloses a boring-free process of a fiberglass ship oil lubrication stern shaft tube and aims at providing the boring-free process of the fiberglass ship oil lubrication stern shaft tube with the advantages that the processing cost is low, the operation is simple, and the precision is high. The boring-free process comprises the following steps that a, welding grooves (2) are formed in support arms (1); b, lower support arms (12) are wedded on a stern shaft hub (3); c, the stern shaft hub (3) is welded on a seamless steel tube (13) and is welded with a stern shaft fore bearing hub (14); d, the stern shaft tube formed by welding in the step c is subjected to finish machining on a lathe; e, positioning plates (4) are welded between upper support arms (11) and the lower support arms (12), the upper support arms (11) and the lower support arms (12) are welded and fixed, fixing plates are welded on the upper support arms (11) after positioning, and the fixing plates are fixed by bolts. The boring-free process of the fiberglass ship oil lubrication stern shaft tube is applied to the technical field of fiberglass ship stern shaft tube mounting.
Description
technical field [0001] The invention relates to a boring-free technology for a fiberglass ship oil lubricated stern shaft tube. Background technique [0002] In small and medium-sized fiberglass boats, in order to maintain a certain stability of the stern shaft, it is often necessary to install a stern shaft bracket at the stern of the ship. The stern shaft bracket is composed of a support arm and a stern shaft hub fixedly connected with the support arm. When in use, the support arm is fixedly installed on the stern of the ship, the stern shaft hub is fixedly sleeved on the stern shaft tube, and the stern shaft tube is sleeved on the stern shaft. At present, welding is often used to connect the support arm and the stern hub. Due to the large structure of the support arm and poor heat dissipation, the stern tube is easily deformed during the welding process. In order to ensure that the installed stern shaft and stern shaft The concentricity between the tubes often needs to ...
