Description

Technical Field

[0001] The utility model belongs to the technical field of angular displacement sensors, and in particular relates to a fixing structure of an angular displacement sensor. Background Art

[0002] An angular displacement sensor is a type of displacement sensor that converts angle measurement into measurement of other physical quantities. It adopts a non-contact design and effectively improves long-term reliability compared with other traditional angular displacement measuring instruments such as synchronous analyzers and potentiometers. For example, the existing patent with publication number CN113280221A discloses "an angular displacement sensor equipped with a coupling, which relates to the technical field of angular displacement sensors, and solves the problem that the existing angular displacement sensors are usually single-body structures and can only detect one detection target, affecting the accuracy of detection; at the same time, the shaft of the angular displacement sensor is a fixed structure, and the shaft cannot rotate to obtain data when non-coaxial rotation occurs. It includes a set of sensing connection holes connected to the front hinge of the sensor base; two sets of magnetic transmission blocks are rotatably connected on both sides of the sensor base; and two sets of displacement sensors installed at right angles are fixedly connected to the top of the sensor base." It can be seen that the application describes a common angular displacement sensor;

[0003] When installing the angular displacement sensor in the prior art, an annular hoop is generally used and fixed to the base with bolts. On the one hand, this traditional fixing method is not very convenient for assembly and disassembly, and is not easy to install in the early stage and to remove after damage in the later stage. On the other hand, excessive pressure may cause the surface of the angular displacement sensor to be squeezed and damaged, affecting the normal use of the angular displacement sensor. For this reason, the utility model proposes an angular displacement sensor fixing structure. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] See also Figures 1 to 3 , is an embodiment of the utility model, which provides a technical solution: an angular displacement sensor fixing structure, including

[0023] The bracket 1 is welded and fixed on the top surface of the base 6, and has an arc-shaped notch at the center of the top for the angular displacement sensor body 5 to enter, and slots 12 for the U-shaped fixed pressure seat 2 to be inserted are symmetrically opened on both sides of the top;

[0024] The U-shaped fixed pressure seat 2 installed on the top of the bracket 1 has its two ends inserted into the two slots 12 respectively, and the inner surface of the U-shaped fixed pressure seat 2 is installed with an arc-shaped rubber pad 4 that is pressed against the angular displacement sensor body 5 to ensure that the angular displacement sensor body 5 is pressed and fixed;

[0025] The limiting mechanism 3 arranged between the bracket 1 and the U-shaped fixed pressure seat 2 includes two movable clamping plates 31 movably installed on the two side surfaces of the bracket 1, a triangular clamping block 32 welded and fixed to the inner side of the top of the movable clamping plate 31, side through-holes 34 opened on the two side surfaces of the bracket 1, and rectangular clamping holes 33 opened on the two end surfaces of the U-shaped fixed pressure seat 2. The ends of the triangular clamping blocks 32 pass through the side through-holes 34 to the rectangular clamping holes 33, which can stably limit the U-shaped fixed pressure seat 2 and ensure the tight fixing stability of the U-shaped fixed pressure seat 2 on the angular displacement sensor body 5. The limiting mechanism 3 also includes two bottom slide grooves 35 opened inside the bracket 1, an installation The spring 36 and the inner slider 38 in the bottom slide groove 35, the bottom connecting rod 37 welded and fixed to the side surface of the inner slider 38, and one end of the bottom connecting rod 37 penetrates the side of the bracket 1 and is fixed to the movable clamping plate 31. If the angular displacement sensor body 5 is to be removed laterally, it is only necessary to first pull the movable clamping plate 31 sideways with force, so that the bottom connecting rod 37 moves sideways with the inner slider 38 and compresses the spring 36, so that the end of the triangular clamping block 32 can be moved out of the rectangular clamping hole 33, and the limit of the U-shaped fixed pressure seat 2 can be released. Then the U-shaped fixed pressure seat 2 can be lifted up, and the U-shaped fixed pressure seat 2 can be separated from the bracket 1. When the angular displacement sensor body 5 is in the correct position, the angular displacement sensor body 5 can be directly removed for inspection and maintenance. When the angular displacement sensor body 5 is installed and fixed in the early stage, the angular displacement sensor body 5 is first placed on the top of the bracket 1, and the positioning block 11 is inserted into the positioning notch 51 to complete the preliminary positioning of the angular displacement sensor body 5. At this time, the U-shaped fixed pressure seat 2 is moved to the top of the angular displacement sensor body 5 and aligned with the slot 12, and then the U-shaped fixed pressure seat 2 is pressed down with force to be inserted into the slot 12, so that the two ends of the U-shaped fixed pressure seat 2 are respectively inserted into the two slots 12, and the triangular clamping block 32 is squeezed to one side so that the movable clamping plate 31 with the bottom The connecting rod 37 and the inner slider 38 move sideways, and the spring 36 is gradually compressed, so that the arc-shaped rubber pad 4 on the inner side of the U-shaped fixed pressure seat 2 fits with the angular displacement sensor body 5, and then the U-shaped fixed pressure seat 2 is pressed down with force, so that the arc-shaped rubber pad 4 is elastically deformed and pressed against the angular displacement sensor body 5 until the U-shaped fixed pressure seat 2 can no longer be inserted. At this time, the triangular clamping block 32 and the movable clamping plate 31 will rebound due to the push of the spring 36, so that the end of the triangular clamping block 32 is clamped into the rectangular clamping hole 33, and the U-shaped fixed pressure seat 2 can be limited again, completing the rapid compression and fixed installation of the U-shaped fixed pressure seat 2 on the angular displacement sensor body 5.

[0026] One end of the spring 36 abuts against the side surface of the inner slide block 38 , and the other end of the spring 36 abuts against the inner wall of the bottom slide groove 35 .

[0027] Among them, rod holes communicating with the bottom slide groove 35 are opened on both side surfaces of the bracket 1, and the rod holes correspond to the bottom connecting rod 37, so that the bottom connecting rod 37 can pass through smoothly later.

[0028] Among them, a pinch block 39 is welded and fixed on the outer surface of the movable clamping plate 31 to facilitate the subsequent operator to pull the movable clamping plate 31 sideways.

[0029] The inner wall of the U-shaped fixed pressure seat 2 is provided with an arc-shaped installation notch, and the top end of the arc-shaped rubber pad 4 is embedded in the installation notch to achieve stable installation of the arc-shaped rubber pad 4.

[0030] Among them, a positioning block 11 is welded and fixed in the arc-shaped notch at the center of the top of the bracket 1, and a positioning notch 51 corresponding to the positioning block 11 is opened on the surface of the angular displacement sensor body 5, which can play a positioning role when the angular displacement sensor body 5 is installed.

[0031] Among them, four corners of the base 6 are provided with reserved installation holes for subsequent fixing of the base 6 to an external substrate.

[0032] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
