Embodiment 1

[0055] Embodiment 1: For measuring the deflection angle of the flat hole of the crank relative to the center line of the flat hole and the round hole

[0056] see figure 1 , Figure 5 and Figure 6 , in this embodiment of the device of the present invention, the corresponding flat hole sleeve pin 7 and round hole sleeve pin 9 shall be selected respectively according to the size of the flat hole and the round hole on the measured crank, and the flat pin shaft 2-1 and the positioning pin Column 5-3 cooperates with suit to connect. First insert the flat hole of the crank to be tested into the flat hole sleeve pin 7, then slide the positioning device 5 so that the round hole sleeve pin 9 on the positioning pin 5-3 can pass through the round hole on the crank to be tested smoothly, and Fasten the positioning device 5 to the ruler body 1; at this time, it is necessary to slowly adjust the main ruler 4 and the slider block 8 to an appropriate position, and when the round hole slee...

Embodiment 2

[0057] Embodiment 2: The device of the present invention can also be used to mark and determine the position of the round hole to be processed on the crank

[0058] Install the crank of the round hole to be processed on the flat pin shaft 2-1 or the flat hole sleeve pin 7, firstly adjust the reading position of the main ruler 4 according to the deflection angle requirements of the flat hole; then according to the hole distance between the round hole and the flat hole Requirement, positioning device 5 is fixed to the definite position of ruler body 1, at this moment replaces positioning pin post 5-3 with circular needle sample punching 11, just can mark the center position of the circular hole to be processed on the crank.

Embodiment 3

[0059] Embodiment 3: The device of the present invention can also be used to measure the deflection angle of the flat hole on the crank assembly

[0060] refer to Figure 7, when the slider pin 6 is assembled on the round hole of the crank, the crank becomes a part; when measuring the deflection angle of the flat hole without disassembling the slider pin 6, the positioning block of the positioning device 5 needs to be removed first 5-7, there will be a U-shaped gap, so first adjust and fasten the proper position of the positioning plate 5-8-1 on the vertical bar 5-4 according to the slider pin 6 on the measured crank, so that the slider The pin shaft 6 is placed in the U-shaped notch; and then according to the outer diameter of the slider pin shaft 6, an appropriate gauge block is selected to be close to the inner surface of the U-shaped notch to determine that the slider pin shaft 6 and the original cylindrical pin The positions of the positioning pins 5-3 coincide with each...

Abstract

The invention discloses a crank flat hole deflection angle measuring tool, which includes a ruler body, a flat pin shaft, a fixed ruler, a main ruler, a slider block, a positioning device, a plurality of round hole bushing pins and flat hole bushing pins, etc. Wherein the ruler body, the flat pin shaft, the fixed length, the main ruler and the slider block form a right triangle. The device of the present invention adjusts the main ruler and the fixed ruler, and adjusts the position of the positioning device on the ruler body, so that the circular hole sleeve pin on the positioning device passes through the circular hole on the crank, and the angle between the fixed ruler and the ruler body It is equal to the deflection angle of the flat hole to be measured, read the reading displayed on the main ruler, and calculate the deflection angle value of the flat hole to be measured according to the specific trigonometric function relation; at the same time, measure the flat pin shaft and positioning pin The distance is the center-to-center distance between the flat hole and the circular hole on the crank part.

Description

technical field [0001] The invention relates to a crank flat hole deflection angle positioning and measuring tool. Background technique [0002] The crank is mainly used in engineering to adjust the angle of the axial fan vane, see Figure 5 , Figure 6 and Figure 7 , which is provided with a flat hole and a positioning circular hole; the crank component is also provided with a slider pin passing through the positioning circular hole on the crank. The angle between the center plane of the planes on both sides of the flat hole and the center line of the flat hole and the round hole is the flat hole deflection angle α; various cranks have flat holes and positioning round holes of corresponding sizes, and the deflection angle of the flat hole is different. [0003] In the prior art, when measuring the deflection angle of the flat hole, only three-coordinate testing equipment can be used. However, due to the limitation of the fixed platform and the operation of professional ...
