Abstract
The utility model discloses a line drawing tool with adjustable angle, which comprises a horizontal base with scale marks on the side surface; one end face of the horizontal base is a reference plane, two sides of the horizontal base are provided with an inward-contracting sliding rail perpendicular to the reference plane, a sliding block perpendicular to the horizontal base is installed on the inward-contracting sliding rail groove, and the sliding block is positioned through a locking bolt on the side face of the sliding block; the upper part of the sliding block is provided with a rotating support which is connected and positioned through a rotating support fixing bolt; one end of the cantilever penetrates through the middle of the rotating support and is positioned through a cantilever fixing bolt on the upper portion of the rotating support, the other end of the cantilever penetrates out of one side of the reference plane, and a scriber is arranged at the front end of the cantilever. The tool effectively solves the problem that the matching size of invisible parts is difficult to calibrate and measure, reduces the difficulty of calibrating and measuring the matching size of the invisible parts, improves the accuracy of the matching size of the invisible parts, reduces the calibration error of the matching size of the invisible parts, and ensures the accuracy of part positioning.
Description
Technical Field
The utility model belongs to the technical field of the setting-out instrument, a but angle regulation's setting-out instrument is related to.
Background
In the process of aircraft assembly, the fit dimension between each part of an aircraft usually has higher requirements, and after the skin on the outer surface of the aircraft is installed, the inner part and the outer part cannot be simultaneously seen, and the fit dimension cannot be directly calibrated and measured. Meanwhile, because the skin parts of the airplane have very large sizes and irregular shapes, the calibration and measurement of the matching sizes are also greatly difficult. The existing manual line drawing measuring mode has large error, is difficult to ensure the uniformity and the accuracy of the fit size, has very low efficiency, often causes rework due to unqualified fit size, increases the work difficulty and the workload, and influences the assembly progress of an airplane.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can effectively overcome current manual survey setting-out a great deal of not enough setting-out instrument of adjustable angle.
The utility model adopts the technical proposal that: the tool comprises a horizontal base with scale marks on the side surface; the method is characterized in that: one end face of the horizontal base is a reference plane, two sides of the horizontal base are provided with an inward-contracting type slide rail groove which is vertical to the reference plane, a slide block which is vertical to the horizontal base is arranged on the inward-contracting type slide rail groove, and the slide block is positioned through a locking bolt on the side face of the slide block; the upper part of the sliding block is provided with a rotating support which is connected and positioned through a rotating support fixing bolt; one end of the cantilever penetrates through the middle of the rotating support and is positioned through a cantilever fixing bolt on the upper portion of the rotating support, the other end of the cantilever penetrates out of one side of the reference plane, and a scriber is arranged at the front end of the cantilever.
The utility model provides a pair of line drawing instrument of adjustable angle, this instrument has solved invisible type part cooperation size effectively and has been difficult to mark and the measuring problem, has reduced the degree of difficulty that such kind of cooperation size was markd and was measured, has improved the degree of accuracy of such kind of part cooperation size, has reduced the calibration error of such kind of part cooperation size, has guaranteed the accuracy of part location. The utility model has the advantages of simple structure and reasonable design, the workman operates more conveniently, and convenience simple to use, subsidiary interior contracting type track groove, the different cooperation size's of perfect adaptation demarcation and measurement, the practicality is strong.
Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 is a schematic view of the three-dimensional structure of the present invention.
In the figure: 1 is a horizontal base; 2 is a slide block; 3 is a locking bolt; 4 is a rotary support; 5 is a cantilever; 6, a marking pin; 7 is a rotary support fixing bolt; 8 is a cantilever fixing bolt; 9 is an inward-contracting type slide rail groove; and 10 is a scale mark. A is a reference plane.
Detailed Description
As shown in the figure, the utility model discloses a horizontal base 1 that the side is equipped with scale mark 10. One end face of the horizontal base 1 is a reference plane A, two sides of the horizontal base are provided with an inward-shrinkage type slide rail groove 9 perpendicular to the reference plane A, and a slide block 2 perpendicular to the horizontal base 1 is installed on the inward-shrinkage type slide rail groove 9. Thus, the sliding block 2 can slide back and forth along the horizontal base 1 through the inner-contracting rail sliding groove 9. The slide 2 is positioned by means of a locking bolt 3 on its side. The upper part of the sliding block 2 is provided with a rotating support 4 which is connected and positioned through a rotating support fixing bolt 7. One end of the cantilever 5 penetrates through the middle of the rotating support 4 and is positioned through a cantilever fixing bolt 8 at the upper part of the rotating support 4, the other end of the cantilever penetrates out of one side of the reference plane A, and a line drawing needle 6 is arranged at the front end of the cantilever.
The utility model discloses a working process as follows:
s1: loosening the locking bolt 3, moving the sliding block 3 to a proper scale according to the actual matching size calibration requirement, and screwing the locking bolt 3;
s2: placing the tool in the part, wherein the reference plane A is tightly attached to the reference surface of the internal part;
s3: loosening the fixing bolt 7 of the rotary support, and adjusting the angle of the rotary support 4 according to the surface appearance of the external part to ensure that the line drawing needle 6 is just attached to the surface of the external part;
s4: moving the tool along the reference surface of the internal part, keeping the reference plane A tightly attached to the reference surface of the internal part in the moving process, and applying a certain pressure to the line drawing needle 6 to make a calibration line on the surface of the external part;
s5: if the fit sizes of the internal and external parts need to be measured, the slide block 2 can be moved according to the actual size position to enable the reference plane A and the line drawing needle 6 to be placed at the 2 measured references, and at the moment, the reading is carried out, so that the size measurement can be completed.
