Problems solved by technology

The first method is to use a deep hole drilling machine and a CNC four-axis machining center for processing. Two sets of different fixtures are required on two different machine tools; The technical requirements for finding the datum are high
The second method is to use a large gantry drilling machine for processing. Two sets of different fixtures are used, and the process of changing fixtures is cumbersome, which can ensure the processing accuracy but is inefficient.
The third method is to use a high-end CNC five-axis machining center for processing, only one set of molds is required, which can guarantee accuracy but is expensive

Embodiment Construction

[0033] The present invention will be further described now in conjunction with accompanying drawing.

[0034] see Figure 1 to Figure 6 , Figure 1 to Figure 6 Shown is an embodiment of the present invention, which includes a clamping system 1 , an indexing system 2 and a limiting system 3 . The clamping system 1 includes a V-shaped support block 1-2 for placing the pipe body. First, the reference level ruler 1-1 is rotated around the pin shaft 1-5 from the ruler base 1-4 to stand up, and the pipe body is placed on the V-shaped support block 1-2, and one end is clamped by the four-jaw chuck 1-3. tight.

[0035] The indexing system includes an X-axis rotation positioning mechanism 2-1, which controls the rotation of the tube around its central axis by driving a four-jaw chuck 1-3. The X-axis rotary positioning mechanism 2-1 uses an electric control four-jaw chuck 1-3 to complete the rotation and positioning of the workpiece around the X-axis (ie, the central axis of the pip...

Abstract

The tooling and fixture used to manufacture the offset pipe body of the completion device. The clamping system includes a V-shaped support block for placing the pipe body; the indexing system includes: X-axis rotary positioning mechanism, which controls the pipe body by driving a four-jaw chuck Rotate around the central axis; and the Z-axis rotary positioning mechanism controls the rotation of the tube body around the vertical central axis through the rotating shaft; the limit system includes several locking mechanisms to limit the position after the Z-axis rotary positioning mechanism rotates. The invention can flexibly adjust the angle between the pipe body and the fixed tool. In the operation of processing multiple inclined holes or straight holes, the original two or more processes are combined into one, the operation is simplified, the processing efficiency is improved, and the production cost.

Description

technical field [0001] The invention relates to a device for manufacturing a pipe body, in particular to a tooling fixture used for manufacturing an offset pipe body of a well completion device. Background technique [0002] At present, there are three processing methods for pipe bodies with oblique holes and deep straight holes. The first method is to use a deep hole drilling machine and a CNC four-axis machining center for processing. Two sets of different fixtures are required on two different machine tools; Finding the datum requires high technical requirements. The second method is to use a large gantry drilling machine for processing. Two sets of different fixtures are used, and the process of changing the fixtures is cumbersome, which can ensure the machining accuracy but is inefficient. The third method is to use a high-end CNC five-axis machining center for processing, which only requires a set of molds, which can guarantee accuracy but is expensive. [0003] In ...
