Embodiment

[0016] like figure 1 As shown, the fixed seat to ensure the positioning accuracy includes a base 4, and the base 4 is provided with several positioning holes 5, and the positioning holes 5 are through holes formed on the upper end surface of the base 4, and each through The holes are all in communication with the wall of the base 4 ; the preferred number of positioning holes 5 is four, and they are evenly distributed on the base 4 .

[0017] The positioning hole 5 is used as the installation channel of the grounding bolt, and the nut of the grounding bolt is in contact with the upper surface of the base 4. The size of the nut of the grounding bolt is larger than the size of the positioning hole 5, so that the nut can be clamped on the base 4. During loading and unloading, the grounding bolt can be easily taken out, avoiding the phenomenon of interference, and the positioning hole 5 is provided to increase the stability during work, so that the stability of the fixing seat is h...

Abstract

The invention discloses a fixed base ensuring positioning precision. The fixed base ensuring positioning precision comprises a base, wherein the base is provided with multiple positioning holes; the positioning holes are through holes formed by inwards sinking the upper end face of the base, and each through hole is communicated with the wall surface of the base; the fixed base is placed on a level ground; an opening of a groove points upwards; four positioning bolts are utilized to penetrate the positioning holes; the end heads of the positioning bolts stretch into the underground; screw caps tightly press the base; a work-piece is placed in the groove and is tightly clamped through sidewalls of a support post, so that the work-piece is supported. The fixed base can efficiently solve the toppling problem, is fixed more steadily, is simple in structure, is good for positioning the positioning holes of the opening, is convenient for assembling and disassembling a grounding bolt, and avoids an interference problem.

Description

technical field [0001] The invention relates to a fixed seat, in particular to a fixed seat for ensuring positioning accuracy and a method for using the same, belonging to the field of mechanical processing equipment. Background technique [0002] Petroleum, also known as crude oil, is a viscous, dark brown (sometimes greenish) liquid. There are oil reserves in parts of the upper crust. The nature of petroleum varies with the place of origin, the density is 0.8 ~ 1.0 g / cm3, the viscosity range is very wide, the freezing point varies greatly (30-60 degrees Celsius), the boiling point ranges from room temperature to above 500 degrees Celsius, and is soluble in many organic solvents , Insoluble in water, but can form emulsion with water. However, the composition and appearance of oil in different oil fields can be greatly distinguished. Petroleum is mainly used as fuel oil and gasoline, and fuel oil and gasoline constitute one of the most important primary energy sources in ...
