Technical Field

[0001] This invention belongs to the field of pipeline processing technology and relates to a boring tool holder device for thinning the inner wall of pipelines in industries such as petroleum, chemical, and natural gas, or for beveling the inner wall of pipelines. Background Technology

[0002] With the increasing demand for pipeline installation and maintenance in various fields, the inner wall of pipelines must be internally machined before on-site socket welding. In some cases where high weld quality is required, an internal bevel needs to be drilled at a certain depth inside the pipeline to meet welding requirements. However, the processing equipment currently available on the market can only drill internal and external bevels on the end face, which cannot meet market demand. To solve this technical problem, a brand-new boring tool holder device has been invented. This device solves the technical problems of boring the inside of the plug-in pipeline and internal bevel processing at a certain boring depth, thus meeting the technical requirements for bevel in the next process of socket welding. Summary of the Invention

[0003] The purpose of this invention is to provide a boring tool holder device. This device has a novel concept and ingenious design, which can meet the requirements of internal boring and internal beveling processing of pipes with different diameters and wall thicknesses on site. At the same time, the tool holder is positioned and fixed by pressure blocks, making installation and disassembly extremely convenient.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a boring tool holder device, including a fixed plate, a left support plate, a right support plate, a tool holder slider, and a vertical motion component.

[0025] A boring tool holder device includes a fixed plate 1, a support plate 2, an adjusting bolt 4, a copper knob 5, a tool holder slider 7, and a vertical motion component 8. The fixed plate 1 is fixed to the front of the tool holder slider by bolts and a groove fit. The fixed plate 1 connects to a left support plate 2 and a right support plate 3, which are fixed to both sides of the fixed plate. The vertical motion component 8 is fixed between the two support plates by the adjusting bolt 4 and the copper knob 5. The vertical motion component 8, from top to bottom, consists of a top handwheel 9 connected to a feed screw 16. The top of the feed screw 16 is fixed inside a graduated cylinder 11 by a pressure cap 10, a spacer, and a thrust bearing 15. The feed screw 16 is fitted and fixed to a feed seat 17 inside a telescopic rod 14. The feed screw 16 feeds... The seat 17 drives the telescopic rod 14 to move vertically. The pressure cap 10 is fixed to the top of the scale cylinder 11, and the bottom of the scale cylinder 11 is fixed to the base 12. The bottom of the base 12 is connected to the fixed copper nut seat 13. The guide block 18 is fixed in the middle of the copper nut seat 13 by a snap ring. With the guide groove on the telescopic rod 14, the telescopic rod 14 moves vertically without rotating. The guide block 18 realizes the guiding function. The bottom sides of the copper fixed seat 13 are provided with positioning pins. The left support plate 2 and the right support plate 3 are provided with corresponding fixing holes. The copper fixed seat 13 is rotatably connected to the support plate 2 through the positioning pins and fixing holes. The left support plate 2 and the right support plate 3 are provided with arc-shaped grooves corresponding to the fixing holes. The adjustment bolts are used to realize the angle rotation function. The copper knob 5 is fixed in the arc-shaped groove by the adjusting bolt 4 at the top of the right support plate 3. The other end of the adjusting bolt 4 is fixed in the arc-shaped groove of the left support plate 2. At the same time, the adjusting bolt 4 is also connected and fixed to the vertical motion component 8. A spring pin 6 is provided on the upper part of the vertical motion component 8 near the copper knob 5 for vertical positioning. Two positioning pins are provided on the left and right sides of the bottom of the vertical motion component 8 to ensure that the vertical motion component 8 can rotate around the pin shaft within a certain range.

[0026] The tool holder slider 7 can drive the boring tool holder device to move horizontally via a lead screw, and the vertical movement component 8 can move vertically via a rotating handwheel 9. Therefore, the boring tool holder device can move in any direction along the X, Y and Z axes, satisfying the processing of pipes at any position along the axial and radial axes.

[0027] Specific example: First, fix the boring tool holder device before the external clamping pipe cutting motor. Rotate the dial wheel to drive the boring tool holder to move radially along the pipe to the appropriate position. Turn on the power to start the equipment. Manually rotate the handwheel 9 to achieve axial movement along the pipe. The scale indication on the scale cylinder 11 indicates the precise boring function. After the boring is completed, when the inner beveling of the internal step part is required, loosen the adjusting bolt 4 and press down the spring pin 6. Hold the scale cylinder 11 and rotate it counterclockwise according to the beveling angle requirement. Observe that the copper knob 5 coincides with the required angle. At this time, tighten the adjusting bolt in place, and the inner beveling can be performed.
