Embodiment 2
[0023] like image 3 As shown, on the basis of Embodiment 1, the above-mentioned fixed disc 31 and the movable disc 21 face each other, and grooves for fixing springs are provided on the two adjacent end surfaces of the fixed disc 31 and the movable disc 21 22. A slider 4 for fine-tuning the position of the spring is arranged in the groove 22, and a fixing bolt is arranged on the slider 4. Scales are provided at the lower edges of the grooves 22 on the end faces of the fixed disc 31 and the movable disc 21 to precisely adjust the fixed positions of the springs so that the measured springs are on a straight line.
[0024] The mounting cylinder 33 is also provided with a ring groove 32 for mounting the spring and a spring clip 34 for fixing the spring, which can also be used for fixing the spring and are suitable for different types of springs.
[0025] The above-mentioned test base 1 is installed on the ground through four damping devices 5, and the damping devices 5 adopt dam...

The invention discloses a fixing device with strong universality for testing spring torque. The fixing device with the strong universality for testing the spring torque comprises a testing machine base (1), and a fixed support (2), a sliding seat (3) and a pair of sliding rails (5) are arranged on the testing machine base (1). The fixed support (2) is fixedly arranged on the left side of the testing machine base (1), and the fixed support (2) is provided with a movable disc (2) used for fixing a spring. The sliding seat (3) is arranged on the sliding rails (5) and is connected with two screw rods (6, 7) through screw rod nuts, the two screw rods (6, 7) are parallel to each other, one ends of the two screw rods (6, 7) are both connected on the fixed support (2), the other ends of the two screw rods (6, 7) are both connected to the output shafts of driving motors (8, 9), and the sliding seat (3) is provided with a fixed disc (31) used for fixing the spring and a mounting column (33). The fixing device with the strong universality for testing the spring torque supports the torque testing of springs with different lengths, is strong in universality, and supports accurate adjustment of spring positions, measurement is made to be more accurate, the structure is simple and compact, and cost is low.
Description
technical field [0001] The invention relates to mechanical product testing equipment, in particular to a highly versatile fixing device for spring torque testing. Background technique [0002] In recent years, with the development of modern industrial technology, various springs have been widely used in my country, and the requirements for the characteristics of springs are getting higher and higher. At the same time, more precise requirements are put forward for the measurement of springs, especially in the Precision machinery, instrumentation industry, etc. [0003] Traditional measurement methods can no longer meet the precise measurement requirements of springs. Therefore, more and more measurements use torque sensors, angle sensors and other sensors for precise measurement, and the measurement parameters are dynamically displayed during the test process and can be stored in the computer or print it out. [0004] In the process of spring measurement, it is very importa...
