Problems solved by technology
[0002] The angle between the arms at both ends of the torsion spring is a spatial angle. If you use an ordinary angle ruler to measure, you can only project the arms at both ends of the spring onto the paper and then measure it. If there are many springs, the process of measuring the angle is very cumbersome. Invisibly increase the production cycle and cost
[0003] figure 1 As shown, when the measuring tool is not used in the prior art, when the operator checks and measures the angle of the two arms of the spring, he places the spring vertically, projects the positions of the two arms, and uses a protractor to measure the α angle, which is not only cumbersome to operate, but also There is an error

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The following examples are only used to illustrate the present invention, and are not intended to limit the protection scope of the present invention.
[0018] image 3 and Figure 3a As shown, the torsion spring space angle measuring tool of the present invention includes a sleeve 1, and the spring 4 is put into the sleeve 1. One end of the sleeve 1 has a groove portion, and the groove portion is arranged along the circumferential direction of the sleeve. Two notches 2 are arranged opposite to each other. The width a of the notch 2 is 5.5mm, which can fix the straight arm 41 at the right end of the spring. The other end of the sleeve 1 is formed with a protruding part along the center line of the sleeve 1. The protruding part is used to place the curved arm 42 at the left end of the spring. The protruding part is a cylindrical groove 3, and th...

The invention discloses a torsional spring space angle measuring tool. The torsional spring space angle measuring tool comprises a sleeve, wherein one end of the sleeve is provided with a groove portion, the groove portion comprises two notches which are arranged along the peripheral direction of the sleeve, the two notches are oppositely arranged and fix a straight arm at the right end of a spring, a projecting part is formed at the other end of the sleeve along the center line of the sleeve, and the projecting part is used for placing a bent arm at the left end of the spring and is a cylindrical slot. When the torsional spring space angle measuring tool is used for measuring the spring, the spring is put into the sleeve, the arm at one end of the spring is fixed, an angle required by the spring is 90 minus and plus 8 degrees, the interval range is labelled at the other end of the sleeve, the spring is put into the sleeve, and the spring is qualified if the spring is in the labelled range. The torsional spring space angle measuring tool disclosed by the invention can effectively shorten an inspection period in a part production process, and production cost is reduced.
Description
technical field [0001] The invention relates to a measuring tool, in particular to a torsion spring space angle measuring tool. Background technique [0002] The angle between the arms at both ends of the torsion spring is a spatial angle. If you use an ordinary angle ruler to measure, you can only project the arms at both ends of the spring onto the paper and then measure it. If there are many springs, the process of measuring the angle is very cumbersome. Invisibly increased the production cycle and cost. [0003] figure 1 As shown, when the measuring tool is not used in the prior art, when the operator checks and measures the angle of the two arms of the spring, he places the spring vertically, projects the positions of the two arms, and uses a protractor to measure the α angle, which is not only cumbersome to operate, but also There is an error. [0004] Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the inven...
