Description

Technical Field

[0001] This utility model relates to the field of vibration table sensor technology, specifically a rigid fixing structure for vibration table sensors. Background Technology

[0002] A vibration table, also known as a vibration exciter or vibration generator, is a device that uses electric, electro-hydraulic, piezoelectric or other principles to obtain mechanical vibration. It is used to simulate vibration environments and test the vibration resistance of products. It is widely used in electronics, electromechanical, automotive, aviation, aerospace and pharmaceutical packaging fields.

[0003] Currently, sensors are often installed on vibration tables to accurately measure, monitor, and analyze the vibration characteristics of the vibration table and its load-bearing objects, providing key data support for experimental verification, quality control, equipment optimization, and safety assessment. Existing vibration table sensors are often fixed using adhesive bonding or clamping methods. Adhesive bonding results in poor sensor stability and easy loosening, while clamping can easily damage the sensor. Therefore, a rigid fixing structure for vibration table sensors is needed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a rigid fixing structure for vibration table sensors, thus solving the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a rigid fixing structure for a vibration table sensor, installed on the vibration table worktable, including a first fixing screw, the first fixing screw having an internal threaded hole in its center, a second fixing screw being installed through the internal threaded hole, the upper end of the second fixing screw extending outward through the internal threaded hole, a sensor structure being provided on the upper surface of the first fixing screw, the sensor structure being threadedly connected to the second fixing screw.

[0006] Preferably, the sensor structure includes a sensor body, a sensor base, and a vertical baffle. The sensor base has a screw hole in the center, and the sensor base is threadedly connected to a No. 2 fixing screw through the screw hole.

[0007] Preferably, the sensor body is disposed at the center of the upper surface of the sensor base, and a plurality of vertical baffles are provided, which are arranged in a circumferential array on the upper surface of the sensor base and located outside the sensor body.

[0008] Preferably, a washer is fitted on the upper end of the outer surface of the first fixing screw.

[0009] Preferably, the workbench surface has a mounting screw hole that mates with the No. 1 fixing screw, and the lower end of the No. 1 fixing screw passes through the mounting screw hole and is threaded with a fastening nut.

[0010] Preferably, the threads on the outer surfaces of the first fixing screw and the second fixing screw are in opposite directions.

[0011] Preferably, the end of the second fixing screw is provided with an internal hexagon screw head, and the lower end face of the first fixing screw is provided with a hidden groove that cooperates with the internal hexagon screw head.

[0012] Preferably, the internal threaded hole and the hidden groove are interconnected.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This rigid fixing structure for vibration table sensors uses a No. 1 fixing screw and a No. 2 fixing screw. When the upper end of the No. 2 fixing screw passes through the internal thread hole and locks the sensor structure, the sensor structure, the No. 1 fixing screw, and the No. 2 fixing screw form a whole. The whole structure is locked to the worktable by the No. 1 fixing screw. The locking direction of the sensor structure and the No. 1 fixing screw is opposite, which can effectively prevent loosening. When the lower end of the No. 1 fixing screw passes through the worktable, the fastening nut is tightened to further ensure the stability of the No. 1 fixing screw. It is convenient for disassembly, maintenance, or replacement in the future.

[0014] 2. The rigid fixing structure used for the vibration table sensor, after the upper end of the No. 2 fixing screw passes through the internal thread hole to lock the sensor structure, the internal hexagonal screw head of the No. 2 fixing screw is inserted into the hidden groove, which does not affect the next step of locking the No. 1 fixing screw to the worktable through the mounting screw hole.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 A rigid fixing structure for a vibration table sensor is installed on the vibration table work surface 6. It includes a first fixing screw 2 with an internal threaded hole 201 in the center. A second fixing screw 4 is installed on the first fixing screw 2 through the internal threaded hole 201. The upper end of the second fixing screw 4 extends out of the external area through the internal threaded hole 201. A sensor structure 1 is provided on the upper surface of the first fixing screw 2. The sensor structure 1 is threadedly connected to the second fixing screw 4.

[0019] The sensor structure 1 includes a sensor body 101, a sensor base 102, and a vertical baffle 104. The sensor base 102 has a screw hole 103 in the center. The sensor base 102 is threadedly connected to the second fixing screw 4 through the screw hole 103. When the upper end of the second fixing screw 4 passes through the internal thread hole 201, the sensor base 102 can be effectively threadedly connected to the second fixing screw 4 through the screw hole 103, thereby locking the sensor structure 1.

[0020] The sensor body 101 is located at the center of the upper surface of the sensor base 102. Several vertical baffles 104 are arranged in a circular array on the upper surface of the sensor base 102 and located outside the sensor body 101. By providing the vertical baffles 104, the sensor body 101 can be effectively protected and prevented from being damaged by collision.

[0021] The first fixing screw 2 has a washer 3 fitted on its upper outer surface. The worktable 6 has a mounting screw hole that mates with the first fixing screw 2. The lower end of the first fixing screw 2 passes through the mounting screw hole and is threaded with a fastening nut 5. The threads on the outer surfaces of the first fixing screw 2 and the second fixing screw 4 are opposite in direction. When the upper end of the second fixing screw 4 passes through the inner thread hole 201 and locks the sensor structure 1, the sensor structure 1, the first fixing screw 2, and the second fixing screw 4 form a whole. The whole structure is locked on the worktable 6 by the first fixing screw 2. The locking directions of the sensor structure 1 and the first fixing screw 2 are opposite, which can effectively prevent loosening. When the lower end of the first fixing screw 2 passes through the worktable 6, the fastening nut 5 is tightened to further ensure the stability of the first fixing screw 2.

[0022] Among them, the end of the second fixing screw 4 is provided with an internal hexagon screw head 401, and the lower end face of the first fixing screw 2 is provided with a hidden groove 202 that cooperates with the internal hexagon screw head 401. The internal thread hole 201 and the hidden groove 202 are interconnected. When the upper end of the second fixing screw 4 passes through the internal thread hole 201 to lock the sensor structure 1, the internal hexagon screw head 401 of the second fixing screw 4 is inserted into the hidden groove 202, which does not affect the next step of locking the first fixing screw 2 on the workbench 6 through the mounting screw hole.

[0023] Working principle: When the upper end of the second fixing screw 4 passes through the internal thread hole 201, the sensor base 102 can be effectively threadedly connected to the second fixing screw 4 through the screw hole 103, thereby locking the sensor structure 1. After the upper end of the second fixing screw 4 passes through the internal thread hole 201 and locks the sensor structure 1, the sensor structure 1, the first fixing screw 2 and the second fixing screw 4 form a whole. The whole structure is locked on the worktable 6 by the first fixing screw 2. The locking direction of the sensor structure 1 and the first fixing screw 2 is opposite, which can effectively prevent loosening. When the lower end of the first fixing screw 2 passes through the worktable 6, tighten the fastening nut 5 to further ensure the stability of the first fixing screw 2.

[0024] Furthermore, after the upper end of the second fixing screw 4 passes through the internal thread hole 201 to lock the sensor structure 1, the internal hexagonal screw head 401 of the second fixing screw 4 is inserted into the hidden groove 202. This does not affect the next step of locking the first fixing screw 2 onto the workbench 6 through the mounting screw hole. The vertical baffle 104 effectively protects the sensor body 101 and prevents it from being damaged by collision.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
