Embodiment Construction

[0015] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0016] figure 1 and figure 2 The shown adjustable V-shaped support seat includes a V-shaped seat 1, a slider 2, a pin 3, a screw 4, an axle sleeve 5, a handle 6, an axle 7 and a screw sleeve 8. The shaft 7 is a screw shaft, the left end is provided with a left-handed external thread, the right section is provided with a right-handed external thread, and the right end of the shaft 7 is equipped with a handle 6 . The main body of the screw sleeve 8 is a hollow tube, and the outer wall at one end is a cone with a conical angle of 20° to 30°. A screw sleeve 8 installed with the small end of the cone facing to the right has a left-handed thread that matches the shaft 7, and the small end of the cone is Another screw sleeve 8 installed towards the left is a right-handed screw thread that is matched with the shaft 7 . The bottom of the V-s...

Abstract

The invention discloses an adjustable V-shaped supporting seat. The adjustable V-shaped supporting seat comprises a V-shaped seat, sliding blocks, pins, screws, shaft sleeves, a handle, a shaft and swivel nuts A transverse through hole is formed in the center of the bottom of the V-shaped seat, the inclined faces of the two sides of a V-shaped groove located in the upper portion are each providedwith a rectangular counter bore, a vertical hole communicated with the transverse through hole is formed in the center of the bottom of each counter bore, and the pins are installed in the vertical holes. Each sliding block is a rectangular block with a cut corner, the sliding blocks are assembled in preset counter bores in the inclined planes at the two sides of the V-shaped seat, and the slidingblocks with the set height are locked through the screws installed on the side faces of the V-shaped seat. The shaft is a screw shaft provided with a right-hand thread and a left-hand thread, the matched swivel nuts are screwed on the two ends of the shaft to be then plugged into the transverse through hole of the V-shaped seat together, the two ends of the shaft are axially positioned and connected through the shaft sleeves respectively, the handle is rocked to drive the two swivel nuts to do relative axial displacement through the shaft, and therefore a wedging type adjusting structure withthe pins at the two sides and the sliding blocks synchronously ascending and descending is formed.

Description

technical field [0001] The invention belongs to a technical solution in the technical field of fixtures for mechanical processing. Specifically, the invention relates to a V-shaped support seat, especially an adjustable V-shaped support seat. Background technique [0002] Oil drill pipe joints are a typical thick-walled pipe fittings. It is divided into internal thread joints and external thread joints. The two supporting oil pipe joints are connected to the rod body through welding. Due to the different internal threads, external threads and matching sealing structures, the diameters of the outer walls of the oil drill pipe joints at both ends are not equal, forming a section of pipe fittings with different outer walls. According to the design requirements of oil drill pipe joints, there must be a process of milling grooves or planes at the relevant outer walls in the manufacturing process. Due to the objective size difference of the outer walls of both ends of the oil dri...
