Description

Technical Field

[0001] The utility model relates to an auxiliary tool for measuring workpiece dimensions, belonging to the technical field of steel component production measurement. Background Art

[0002] The dimension verification step is indispensable in the production and installation process of steel components. However, in many cases, due to the rounded corners of steel pipes, it is necessary to use a square ruler for auxiliary measurement when measuring the dimensions. Traditional square ruler-assisted measurement, especially for long-distance measurement, requires three people to ensure the accuracy of dimension measurement. One person fixes the square ruler, one person fixes one end of the tape measure, and the other person measures with a ruler. The measurement process is not only cumbersome, but also requires a lot of personnel, and the measurement accuracy and efficiency will be affected. In view of this situation, a simple measurement auxiliary tool is designed. Summary of the invention

[0003] The utility model aims to solve the problem of dimension verification of steel components during production and installation, and discloses an auxiliary tool for measuring the dimension of a workpiece.

[0004] The technical solution implemented by the utility model is as follows: an auxiliary tool for measuring the size of a workpiece, comprising a square ruler body with a slide groove, a cylindrical slider with a slot and a thread, and a nut; the square ruler body with a slide groove is a planar disc structure composed of a 90° central angle and a concentric circular groove; the cylindrical slider with a slot and a thread can be inserted into the circular groove and move along the circumference of the circular groove; the nut cooperates with the internal thread of the cylindrical slider with a slot and a thread, and fixes the cylindrical slider with a slot and a thread on the square ruler body with a slide groove; the 90° central angle of the square ruler body with a slide groove can be used to place the workpiece to be measured.

[0005] The cylindrical slider with a slot and a thread is a T-shaped cylindrical structure, which is short at the top and long at the bottom; a small rectangular slot is opened in the middle of the upper end face, and an internal screw hole is opened at the bottom, which matches the external thread of the nut; the small outer circle diameter at the bottom is smaller than the slot width of the main body of the square ruler with a slot; the large outer circle diameter at the top is larger than the slot width of the main body of the square ruler with a slot; the length of the lower cylinder is smaller than the thickness of the main body of the square ruler with a slot.

[0006] One end of the nut is an external thread, and the other end is a disc, the diameter of which is larger than the groove width of the main body of the square ruler with the sliding groove.

[0007] The slot of the cylindrical slider with a slot and a thread can be inserted into the hook of the tape measure.

[0008] The beneficial effect of the utility model is that the utility model improves the traditional square ruler, changes the main structure of the square ruler, and adapts to different measuring angles by designing a combination of a slide groove and a slider, and fixes the hook of the tape measure by a slot designed on the slider, so as to ensure the accuracy and efficiency of our measurement.

[0016] The specific implementation of the utility model is shown in the accompanying drawings.

[0017] The present embodiment is a workpiece size measurement auxiliary tool, comprising a square ruler body 1 with a slide groove, a cylindrical slider 2 with a slot and a thread, and a nut 3. The square ruler body 1 with a slide groove is as shown in FIG. Figure 1 and Figure 2 As shown; the cylindrical slider 2 with slot and thread is as shown Figure 3 and Figure 4 As shown; Nut 3 as Figure 5 shown.

[0018] like Figure 1 and Figure 2 As shown, the main body 1 of the slide groove square ruler of this embodiment is a planar disc structure composed of a central angle of 90° and a concentric circular groove.

[0019] like Figure 3 and Figure 4As shown, the cylindrical slider 2 with a slot and a thread of the present embodiment can be inserted into the annular groove and move in a circular motion along the annular groove; the nut 3 of the present embodiment cooperates with the internal thread of the cylindrical slider 2 with a slot and a thread, and fixes the cylindrical slider 2 with a slot and a thread on the main body 1 of the square ruler with a slot; the workpiece to be measured is placed at the 90º central angle of the main body 1 of the square ruler with a slot of the present embodiment.

[0020] The working principle of this embodiment is as follows: first, insert the cylindrical slider 2 with a slot and a thread into the main body 1 of the square ruler with a slot, and then screw the nut 3 into the screw hole of the cylindrical slider 2 with a slot and a thread. At this time, the square ruler is assembled.

[0021] like Figure 6 As shown, when measuring, fit the 90° central angle of the main body 1 of the sliding groove square ruler to the surface of the workpiece 5 to be measured, then insert the hook of the tape measure 4 into the end face slot of the cylindrical slider 2 with slots and threads, and finally pull the tape measure 4 to the other end of the workpiece to be measured. When the tape measure 4 is straightened, the 100 mm scale position of the tape measure 4 will be exactly at the right angle position of the square ruler 1, so the final measured value of the workpiece 5 to be measured is the actual measured value of the ruler minus 100 mm, that is, the actual measured value of the workpiece 5.

[0022] Only two people are needed during the measurement process, one is responsible for fixing the auxiliary square ruler, and the other is responsible for measuring with the ruler. No personnel are required to fix the measuring starting point of the tape measure. This not only improves the measurement accuracy, but also greatly improves the measurement efficiency.
