Description

Technical Field

[0001] This utility model relates to the field of angle coil number positioning fixtures, and in particular to a spring angle coil number positioning fixture. Background Technology

[0002] Springs, as extremely important mechanical components, are widely used in numerous industrial fields such as automobiles, aerospace, electronic equipment, and medical devices. Different applications place strict and precise requirements on the number of coils and the angle of springs. The number of coils directly determines the spring's stiffness, strength, and deformation, while deviations in the angle can cause the spring to malfunction after assembly, affecting the performance and reliability of the entire system. Therefore, accurately controlling the spring's angle and number of coils is crucial during the production and assembly process, necessitating the design of a spring angle and coil number positioning fixture.

[0003] In existing positioning fixtures for spring measurement, there is a lack of effective fixing methods. Due to the elasticity of springs, they are prone to shaking and displacement during measurement. When using simple clamps to fix springs, uneven clamping force or inability to adapt to the shape and size of springs of different specifications can cause the spring's position to change during measurement, which seriously affects the accuracy of the measurement results. This is especially true for some slender or irregularly shaped springs, where traditional fixing methods are difficult to guarantee their stability during measurement. Furthermore, existing positioning fixtures have a spring height measuring structure installed on the left side of the base. This measuring structure can directly obtain the spring's height information, making it easy to measure and detect the spring's height and calculate the number of coils, thus increasing the practicality and convenience of the device. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this utility model is to provide a spring angle coil number positioning fixture to solve the problem mentioned in the background art that the existing positioning fixtures for spring measurement lack effective fixing methods. Due to the elastic characteristics of the spring, it is easy for the spring to shake and shift during measurement. When using simple clamps to fix the spring, the clamping force of the clamps is uneven or cannot adapt to the shape and size of different specifications of springs, which causes the spring position to change during the measurement process, thus seriously affecting the accuracy of the measurement results. Especially for some slender or irregularly shaped springs, traditional fixing methods are difficult to guarantee their stability during the measurement process. In addition, the existing positioning fixture has a spring height measuring structure installed on the left side of the base. This measuring structure can directly obtain the height information of the spring, which is convenient for measuring and detecting the height of the spring and for calculating the number of coils of the spring, thus increasing the practicality and convenience of the device.

[0014] (III) Beneficial Effects

[0015] This utility model provides a spring angle coil number positioning fixture, which has the following beneficial effects:

[0016] 1. This spring angle coil positioning fixture, through the setting of the fixing mechanism, when the device is to be used, first place the outer spring in the middle of the top surface of the chassis, and then adjust the extension length of the telescopic hydraulic rod inside the base according to the height and thickness of the outer spring, so that the top plate outside the base can support the inside of the spring and fix the outer spring in place. This plays the role of supporting and fixing the outer spring from the inside, avoiding the phenomenon of shaking or displacement during measurement, which would cause the spring to change position during the measurement process, thus seriously affecting the accuracy of the measurement results.

[0017] 2. This spring angle coil positioning fixture, through the setting of the measuring mechanism, requires the height to be measured after the external spring is fixed when the device is to be used. Then, based on the width data of one coil of the spring, the specific number of coils is calculated. A measuring ruler A is installed on the left side of the chassis. The surface of the measuring ruler A is set with a data scale. The data on the data scale corresponding to the height of the external spring is the height of the external spring. Then, the height is calculated.
