[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0031] The present application provides a three-axis composite sensor to solve the problems in the above related technologies and monitor vibration in multiple directions.
[0032] In order to make the above purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.
[0033] Referring to Figs. 1-6 The present embodiment provides a three-axis composite sensor, which comprises a circuit board 5, a joint 6, a shell 2 and a structure.
[0034] The circuit board 5 is provided with a sensor module 53, an operational amplifier circuit module 52 and a power supply circuit module 51. The sensor module 53 can simultaneously collect vibration signals and impact pulse signals in three axial directions (X-axis direction, Y-axis direction and Z-axis direction, and any two directions are perpendicular to each other) of space. The operational amplifier circuit module 52 is used for amplifying the signals output by the sensor module 53, and the power supply circuit module 51 is used for supplying power to the circuit board 5. The joint 6 is provided with a wire, which is electrically connected with the operational amplifier circuit module 52 and the power supply circuit module 51 respectively, so as to output the signals processed by the operational amplifier circuit module 52 to the outside and transmit the external power to the power supply circuit module 51. The shell 2 is sleeved outside the circuit board 5 and connected with the joint 6. The structure is arranged between the circuit board 5 and the shell 2 and fixedly connected with the circuit board 5 and the shell 2 respectively, and used for transmitting the vibration of the shell 2 to the circuit board 5.
[0035] The working principle of the three-axis composite sensor in the embodiment is as follows:
[0036] The structure is fixedly connected with the circuit board 5 and the shell 2 respectively, forming a whole, which is beneficial to force transmission. In use, the shell 2 is fixed on a workpiece which needs to be monitored, and the vibration of the workpiece is transmitted to the circuit board 5 through the shell 2 and the structure, and then collected by the sensor module 53. The collected signals are transmitted to the operational amplifier circuit module 52, and then amplified by the operational amplifier circuit module 52 and transmitted to the outside. The wire in the joint 6 has at least two strands, one of which is connected with the power supply circuit module 51 and used for transmitting power to the power supply circuit module 51, and the other of which is connected with the operational amplifier circuit module 52 and used for transmitting the signals amplified by the operational amplifier circuit module 52 to the outside.
[0037] As a possible example, in the embodiment, the joint 6 and the shell 2 are both made of metal, so that the joint 6 and the shell 2 can play the role of electromagnetic shielding, thereby protecting the internal circuit board 5.
[0038] As a possible example, in the embodiment, the joint 6 and the shell 2 are welded together to improve the connection strength of the connection part of the joint 6 and the shell 2 and avoid separation under severe vibration. According to different actual needs, those skilled in the art can also use other connection methods, for example, the joint 6 and the shell 2 are connected by adhesion.
[0039] As a possible example, in the embodiment, the structure includes a shielding shell 4 and an insulator 3. The shielding shell 4 is used for electromagnetic shielding. The insulator 3 is arranged between the shielding shell 4 and the shell 2 and used for separating the shielding shell 4 from the shell 2. By arranging the shielding shell 4 in the shell 2, the role of secondary shielding can be played, the electromagnetic shielding effect is improved, and the internal circuit board 5 is better protected. The insulator 3 separates the shell from the shielding shell 4, and no current is transmitted between the shell and the shielding shell 4, so that the shell and the shielding shell 4 can play the role of electromagnetic shielding respectively.
[0040] Exemplarily, the material of the shielding shell 4 is aluminum alloy.
[0041] As a possible example, in the embodiment, the shell 2, the insulator 3, the insulator 3, the shielding shell 4, and the shielding shell 4 and the circuit board 5 are connected by structural adhesive. By using structural adhesive for bonding, the relative positions of the two adjacent components are ensured, thereby improving the consistency of the overall vibration frequency and vibration amplitude.
[0042] As a possible example, in the embodiment, the shielding shell 4 is provided with a strip-shaped groove, and the circuit board 5 is inserted into the strip-shaped groove. Exemplarily, the number of strip-shaped grooves is two and the positions are opposite, and the two side edges of the circuit board 5 are respectively inserted into the two strip-shaped grooves. By using the strip-shaped groove to limit the circuit board 5, on the one hand, it is convenient to install the circuit board 5, and the circuit board 5 can be slidably inserted into the strip-shaped groove and then bonded by structural adhesive; on the other hand, the strip-shaped groove can limit the circuit board 5 from both sides, thereby ensuring the consistency of the vibration frequency and vibration amplitude of the circuit board 5 and the shielding shell 4.
[0043] As a possible example, in the embodiment, the insulator 3 and the shielding shell 4 are concentrically arranged in a cylindrical structure. It can be understood that the end of the shielding shell 4 should be closed by its own end face or adjacent components to ensure its electromagnetic shielding effect.
[0044] As a possible example, in the embodiment, the outer side of the insulator 3 is provided with an outer groove, the inner side of the insulator 3 is provided with an inner groove, the outer groove and the inner groove extend along the axial direction of the insulator 3, and the outer groove and the inner groove are filled with a glue layer. It should be noted that the above structural adhesive can only play a role in fixed connection, and there is still a gap between the adjacent components. Due to the existence of the gap, the vibration frequency and vibration amplitude of the adjacent components may not be consistent, and even collision occurs, which affects the transmission of vibration energy. On the basis of using structural adhesive, the embodiment further fills the gap with a glue layer, which can improve the consistency of the vibration process of the adjacent components.
[0045] Exemplarily, the insulator 3 and the glue layer are both made of epoxy resin material. In actual use, liquid epoxy resin is injected from the end of the outer groove and the inner groove, and the epoxy resin can also diffuse to other gaps after filling the outer groove and the inner groove. The outer groove and the inner groove provide a certain depth size to facilitate the rapid filling of the epoxy resin.
[0046] As a possible example, in the embodiment, the three-axis composite sensor further includes a locking bolt 1. The shell 2 includes a cylinder one and a cylinder two which are fixedly connected at an included angle, the locking bolt 1 passes through the cylinder one, the circuit board 5 and the structure are located in the cylinder two, and the connector 6 is connected to one end of the cylinder two away from the cylinder one.
[0047] Exemplarily, the through hole on the cylinder one through which the locking bolt 1 passes is not provided with internal thread, so that the shell 2 can rotate around the locking bolt 1 before locking, thereby facilitating the adjustment of the installation angle of the shell 2 according to the actual installation space.
[0048] Exemplarily, the cylinder one and the cylinder two are perpendicular to each other and are both in cylindrical shape.
[0049] As a possible example, in the embodiment, the joint 6 has external thread, and the wire in the joint 6 is located in the center of the joint 6. In actual use, the external plug-in module is connected with the joint 6 in a rotating manner, and after rotation, the wire in the center of the joint 6 is connected with the wire in the center of the internal plug-in module.
[0050] The principle and implementation mode of the utility model are described by applying specific examples in the utility model, and the above embodiment is only used for helping to understand the method and core idea of the utility model; meanwhile, for the general technical personnel in the field, according to the idea of the utility model, there will be changes in the specific implementation mode and application range. In conclusion, the content of the specification should not be understood as the limitation of the utility model.
