Description

Technical Field

[0001] The utility model belongs to the field of quadrant inspection and testing, and in particular relates to a high-frequency vibration test fixture device for a quadrant. Background Art

[0002] The quadrant is an angle measuring instrument based on the principle of a level. It is a mechanical reading instrument used to measure the inclination angle and installation angle of a plane or tube or shaft fixed at a specified angle to the horizontal plane. The reliability of the level mechanism, the stability of the adjustment, and the strength of the entire quadrant must be subjected to a high-frequency vibration test on a vibration test bench. The quadrant should not be damaged after the vibration, and the indications should comply with the relevant technical standards. At present, the device used for the vibration test of the quadrant is a rectangular wooden box. During the high-frequency vibration process, the quadrant and its accessories are prone to shaking in the wooden box and on the vibration test platform, which poses a risk of collision and causes inaccurate test data, making it impossible to guarantee product quality. Therefore, a high-frequency vibration test fixture is urgently needed to solve the above problems. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the structure of the utility model;

[0014] Figure 2 This is the structure diagram of the quadrant. DETAILED DESCRIPTION

[0015] In order to make the purpose, content, and advantages of the utility model clearer, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments.

[0016] This embodiment provides a quadrant high-frequency vibration test fixture device, including: a quadrant fixing slot 1, a fixing block 2, a bolt 3, and a set screw 4;

[0017] The quadrant fixing slot 1 is a square structure, with a groove on the upper surface, the quadrant is fixed in the groove, the top and side walls of the quadrant are in contact with the inner wall of the groove, a fixing block 2 is provided above the quadrant, the fixing block 2 is a rhombus structure, threaded holes are provided at the front and rear ends of the fixing block 2, and set screws 4 are provided in the holes;

[0018] The fixing block 2 has an elliptical notch in the middle, and a bolt 3 is arranged in the middle of the notch, and the fixing block is fixed to the bottom of the groove by the bolt 3 .

[0019] The bolt 3 is configured as an M12 hexagonal bolt.

[0020] The set screw 4 is configured as an M10 hexagon socket flat-point set screw.

[0021] When in use, first place the quadrant to be tested in the quadrant fixing slot 1, press the fixing block 2 on the quadrant frame and the quadrant slide, and then use 1 M12 external hexagonal bolt and 2 M10 internal hexagonal flat-end set screws to install them on the middle slot and the threaded holes on both sides of the fixing block 2 to press the fixing block 2 and the quadrant frame to prevent the risk of collision and achieve the purpose of clamping firmly. The frame structure and size of the quadrant are similar to the external structure of the quadrant during the vibration test. It is made of aluminum metal material, which ensures a certain weight and is different from other steel materials that are too heavy, making it easy to move;

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
