Description

Technical Field

[0001] The utility model relates to the technical field of the moving coil structure of a vibration table based on engineering plastics, and particularly relates to a moving coil structure of a vibration table based on engineering plastics. Background Technique

[0002] The moving coil is the core component of the vibration table. It is both a force output component and a force transmission component. When an alternating current is passed through the winding of its driving coil, the driving coil will generate an alternating exciting force, and the exciting force will be transmitted to the test piece through the table surface part of the moving coil to drive the test piece to vibrate. The moving coil structure needs to have sufficiently high stiffness and strength.

[0003] The current moving coil is made by injecting molten aluminum alloy into a special mold. Due to the complex structure of the moving coil, the processing difficulty and precision requirements of the casting parts are relatively high. There are many processing procedures and the error tolerance rate is low. Any mistake in any link may cause the moving coil to be scrapped, resulting in all previous efforts being wasted. There are many factors affecting the qualification rate. At present, the sequence of each link in the production of the moving coil is compact. Any unqualified processing or lack of materials in any link will seriously affect the production progress of the moving coil, and the requirement for coordination is relatively high. Therefore, the current production cost of the moving coil is relatively high. While ensuring the same equipment capacity, the lighter the moving coil quality, the better. At present, the most widely used material in the industry is aluminum alloy. Therefore, a structural material with a smaller density is also very necessary. During the metal casting process of the moving coil, it is easy to produce sand holes due to the influence of metal fluidity, which poses a hidden danger that is not easy to detect in time and has a great impact on the equipment performance indicators. Content of the Utility Model

[0004] The purpose of the present utility model is to provide a moving coil structure for a vibration table based on engineering plastics. The material of this moving coil structure uses engineering plastics, and its mass is 1 / 3 lighter than that of an aluminum moving coil. A lighter moving coil requires less energy to generate vibration. A lighter moving coil is beneficial for a faster response speed and higher sensitivity during operation, which is conducive to improving the equipment indicators, reducing energy consumption, and saving resources. The material of the moving coil structure uses engineering plastics. Due to the processing characteristics of engineering plastics that can be injection molded and extruded, it can be integrally formed with less processing and high precision. High precision can reduce wear and extend the service life of the equipment. The coil winding can be prefabricated, which reduces the requirements for processing technology and is conducive to improving production efficiency. The qualified rate and efficiency of the moving coil finished products are higher. The material of the moving coil structure uses engineering plastics, and a good appearance can be achieved without separate metal oxidation. During the metal casting process of the moving coil, it is prone to sand holes due to the influence of metal fluidity, which poses a hidden danger that is not easily detected and has a great impact on the equipment performance indicators. Using engineering plastics can effectively avoid the hidden danger of fluidity to the equipment performance indicators. This engineering plastic is an engineering plastic after process and formula improvement. In addition to maintaining the original characteristics of non-metallic materials, its strength and hardness are close to those of aluminum alloy materials. In addition, by designing a skeleton with a T-shaped through groove, and a T-shaped support plate with ventilation holes inside the skeleton, cooperating with transverse ribs and inclined ribs, the mass of the moving coil structure is further reduced. At the same time, the strength of the skeleton is enhanced by using the T-shaped support plate, transverse ribs and inclined ribs. The T-shaped support plate has ventilation holes and does not contact the transverse ribs and inclined ribs, increasing the contact area of the skeleton with air and facilitating heat dissipation.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: A moving coil structure for a vibration table based on engineering plastics, including an upper coil seat of the moving coil and a driving coil. The lower end surface of the upper coil seat of the moving coil is fixedly connected with skeletons distributed in a circumferential array. The overall plate body of the skeleton is a right trapezoidal plate. T-shaped through grooves penetrating the plate body are formed on the skeletons. A T-shaped support plate is formed on the inner wall of the skeleton. A number of ventilation holes are formed on the T-shaped support plate. Symmetrical transverse ribs and inclined ribs are formed on both sides of the T-shaped support plate.

[0006] Preferably, the transverse ribs and the inclined ribs have the same thickness, and the transverse ribs and the inclined ribs are combined to form a reinforcing mesh plate.

[0007] Preferably, the ends of the transverse ribs and the inclined ribs are fixedly connected to the inner wall of the skeleton, and the transverse ribs and the inclined ribs do not contact the T-shaped support plate.

[0008] Preferably, symmetrical planes are formed on the outer side wall of the upper coil seat of the moving coil, and connection holes for the conductive vibration module used by the vibration table are formed on the outer planes of the upper coil seat of the moving coil.

[0009] Preferably, an upper table surface is installed on the upper end of the upper coil seat of the moving coil, and a number of fixing holes for installing table surface lead screws are formed on the upper table surface.

[0010] Preferably, a drive coil is fixedly installed outside the lower end of the framework, and a reinforcing ring is fixedly arranged at the upper end of the drive coil.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The moving coil structure uses engineering plastics as the material. The mass is 1 / 3 lighter than that of the aluminum brake coil. A lighter moving coil requires less energy to generate vibration. A lighter moving coil is beneficial for a faster and more sensitive response speed during work, which is conducive to improving the equipment index, reducing energy consumption and saving resources.

[0013] 2. The moving coil structure uses engineering plastics as the material. Due to the processing characteristics of injection molding and extrusion of engineering plastics, it can be integrally formed with less processing and high precision. High precision can reduce wear and extend the service life of the equipment. The coil winding can be prefabricated, which reduces the requirements for processing technology and is conducive to improving production efficiency. The qualified rate and efficiency of the moving coil finished product are higher.

[0014] 3. The moving coil structure uses engineering plastics as the material, and a good appearance can be achieved without separate metal oxidation.

[0015] 4. During the metal casting process of the moving coil, it is easy to produce sand holes due to the influence of metal fluidity, which poses a hidden danger that is not easy to detect and has a great impact on the equipment performance index.

[0016] 5. The engineering plastics are engineering plastics after process and formula improvement. In addition to maintaining the original characteristics of non-metallic materials, the strength and hardness are close to those of aluminum alloy materials.

[0017] 6.
