Description

Technical Field

[0001] This utility model relates to the field of low-noise electric slide table technology, specifically a low-noise electric slide table. Background Technology

[0002] An electric slide table is an automated transmission component that converts the rotary motion of a motor into linear motion. Its main applications include: Industrial automation: In automated production lines, electric slide tables are commonly used for material handling, conveying, and component assembly; Precision machining and manufacturing: In precision machining equipment such as CNC machine tools, grinding machines, and EDM machines, electric slide tables serve as key feed mechanisms, precisely controlling the position and speed of the cutting tool or workpiece to achieve high-precision cutting, grinding, and EDM operations; Inspection and measurement equipment: In inspection equipment such as coordinate measuring machines, optical measuring instruments, and electron microscopes, electric slide tables are used to move the measuring probe or the workpiece being measured, enabling precise measurement of objects at different positions and angles.

[0003] However, some existing electric slides do not have low noise, which may not only interfere with normal communication between staff, but also affect their own performance and reduce their practicality.

[0004] Therefore, those skilled in the art have provided a low-noise electric slide to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a low-noise electric slide table to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A low-noise electric slide table includes a fixed base; several connecting blocks are fixedly connected to the lower front and rear ends of the fixed base, a shock-absorbing box is provided at the lower outer end of the connecting blocks, a buffer plate is fixedly connected to the lower side of the connecting blocks, several lower limit sliding grooves are cut on the left and right sides of the buffer plate, shock-absorbing springs are fixedly connected to the lower front and rear ends of the buffer plate, and a shock absorber is fixedly connected to the middle of the shock-absorbing spring; support side frames are fixedly connected to the upper left and right ends of the fixed base, a rotating shaft is rotatably connected inside the support side frames, a servo motor is fixedly connected to the left side of the rotating shaft, and a rotating lead screw is fixedly connected to the right side of the rotating shaft.

[0007] As a further embodiment of this invention, the outer side of the rotating lead screw is threaded with a movable slide.

[0008] As a further embodiment of this utility model, a motor mounting bracket is provided on the outer side of the servo motor.

[0009] As a further embodiment of this utility model, a number of linear guide rails are fixedly connected to one side of the support side frame, and a number of slots are cut into the outer surface of the support side frame.

[0010] As a further embodiment of this utility model, the outer side of the support frame is provided with several protective shields, and several locking blocks are fixedly connected to one side of the protective shields.

[0011] As a further embodiment of this utility model, movable sliders are fixedly connected to the front and rear ends of the lower side of the movable slide.

[0012] As a further embodiment of this invention, the outer side of the movable slider is provided with an upper limit groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Vibration during equipment operation can be reduced by using shock-absorbing springs and shock absorbers. When starting up, the servo motor drives the rotating screw to rotate and move the sliding table, which will generate a large impact force instantly. When stopping, there will also be an impact from braking. The shock-absorbing springs and shock absorbers can buffer such impact forces. For example, damping springs undergo elastic deformation upon impact, absorbing and storing some energy, while shock absorbers utilize their internal damping structures to dissipate energy. Together, they make the starting and stopping process of the moving slide smoother, avoiding strong vibrations caused by rigid impacts, thereby reducing the transmission of noise and keeping the moving slide relatively quiet during the start and end phases of operation. Especially in applications with frequent starts and stops, this buffering effect can effectively reduce the overall vibration and noise levels, improve the user experience, and help protect other equipment components. Furthermore, during the operation of the moving slide, although precise rotating screws and linear guides ensure linear motion, vibrations are inevitable due to various factors (such as microscopic unevenness on the surface of the linear guides, slight transmission fluctuations in the rotating screws, and load changes). The damping springs and shock absorbers at the bottom act as vibration absorbers, continuously absorbing this vibration energy and preventing it from being transmitted to the mounting base and the surrounding environment. In addition, when the moving slide bears different weight loads, its motion stability will be affected to varying degrees. The presence of damping springs and shock absorbers optimizes the adaptability of the movable slide to load changes. The spring constant of the damping spring can be reasonably selected according to the design load range of the movable slide, so that it can provide appropriate support and cushioning effect when bearing different weight loads; the shock absorber can dynamically adjust the damping force according to load changes, ensuring that the movable slide can still operate smoothly under load changes, without large vibrations or displacement deviations due to sudden increases or decreases in load, further ensuring the stability and accuracy of the movable slide's movement.

[0014] 2. Protective shields provide excellent protection. When the equipment is idle, dust from the surrounding environment gradually settles and adheres to surfaces such as the lead screw, linear guide, and upper limit slide. Even after cleaning before subsequent use, it is difficult to completely remove all dust, affecting the smooth operation between these components, increasing friction and wear. This can lead to problems such as uneven movement, decreased accuracy, and increased noise when the equipment is restarted. Furthermore, the accumulated dust can disrupt the original smooth movement of the equipment. For example, dust particles entering between the lead screws increase the coefficient of friction, affecting the movement accuracy of the moving slide and easily generating additional noise due to increased friction. Protective shields effectively block dust from contacting critical internal components, keeping them clean and ensuring the equipment maintains good performance upon next use. Moreover, when not in use, the equipment may be subject to accidental collisions, compression, or other physical damage, or be damaged by improper stacking of items during storage. The protective shield can serve as an external protective barrier, capable of withstanding a certain degree of external impact, dispersing and buffering these external forces, preventing direct impact on key components inside the equipment (such as rotating lead screws, linear guides, etc.), preventing deformation or damage to components, ensuring the integrity of the moving slide, and enabling it to continue to operate normally and in a low-noise state when needed in subsequent use.

Detailed Implementation

[0020] Please see Figures 1-4In this embodiment of the present invention, a low-noise electric slide table includes a fixed base 1; several connecting blocks 2 are fixedly connected to the front and rear ends of the lower side of the fixed base 1, a shock-absorbing box 3 is provided at the lower outer end of the connecting block 2, a buffer plate 4 is fixedly connected to the lower side of the connecting block 2, several lower limit sliding grooves 5 are slotted on the left and right sides of the buffer plate 4, shock-absorbing springs 6 are fixedly connected to the front and rear ends of the lower side of the buffer plate 4, and a shock absorber 7 is fixedly connected to the middle of the inside of the shock-absorbing spring 6; support side frames 8 are fixedly connected to the left and right ends of the upper side of the fixed base 1, a rotating shaft 9 is rotatably connected inside the support side frame 8, and the left side of the rotating shaft 9 is fixedly connected to A servo motor 10 is connected to the servo motor 10, and a rotating lead screw 11 is fixedly connected to the right side of the rotating shaft 9. A movable slide 12 is threadedly connected to the outer side of the rotating lead screw 11. A motor fixing bracket 13 is provided on the outer side of the servo motor 10. Several linear guide rails 14 are fixedly connected to one side of the support side frame 8, and several slots 15 are cut on the outer surface of the support side frame 8. Several protective shields 16 are provided on the outer side of the support side frame 8, and several locking blocks 17 are fixedly connected to one side of the protective shields 16. Movable sliders 18 are fixedly connected to the front and rear ends of the lower side of the movable slide 12. An upper limit groove 19 is provided on the outer side of the movable slider 18.

[0021] The working principle of this utility model is as follows: When in use, simply place the device in a suitable position using the shock-absorbing box 3, and then move the protective shields 16 on the upper, front, and rear sides of the support side frame 8 outwards until the locking block 17 and the locking groove 15 are no longer in contact. At this point, the fixation between the protective shield 16 and the support side frame 8 is released, and the protective shield 16 can provide good protection. When the device is idle, dust in the surrounding environment will gradually fall and adhere to the surfaces of the rotating lead screw 11, linear guide rail 14, and upper limit slide groove 19. Even if cleaning is performed before subsequent use, it is difficult to completely remove the dust, which will affect the smooth cooperation between these components, increase friction and wear, and cause problems such as unsmooth movement, decreased accuracy, and increased noise when the device is restarted. In addition, the adhered dust will also disrupt the original smooth movement of the device. For example, dust particles entering between the rotating lead screws 11 will increase the coefficient of friction, affecting the motion accuracy of the moving slide 12. It can also easily generate additional noise due to increased friction. The protective shield 16 can effectively block dust, preventing it from contacting the key components inside the equipment, keeping the components clean, and ensuring that the equipment can maintain good performance when it is used again. Moreover, when not in use, the equipment may also be subject to some accidental collisions, squeezing or other physical damage, or be squeezed due to improper stacking of items during storage. The protective shield 16 serves as an external protective barrier, capable of withstanding a certain degree of external impact, dispersing and buffering these forces, and preventing direct impact on critical internal components (such as the rotating lead screw 11 and linear guide rail 14). This prevents deformation and damage to the components, ensuring the integrity of the movable slide 12 and allowing it to continue operating normally and at low noise levels when needed. Then, the servo motor 10 is started, driving the rotating shaft 9 and the rotating lead screw 11 to rotate. The rotating lead screw 11 then drives the movable slide 12 and the movable slider 18 to move horizontally along the upper limit groove 19. The movable slide 12 can then be used normally. During operation, the servo motor 10 will generate slight vibrations, which will cause the fixed base 1 to vibrate up and down. Then, the fixed base 1 will drive the connecting block 2 and the buffer plate 4 to move up and down along the lower limit slide groove 5. During the movement, the buffer plate 4 will squeeze the damping spring 6 and the shock absorber 7, which can reduce the vibration of the equipment during operation. When starting, the servo motor 10 will drive the rotating screw 11 to rotate and drive the moving slide 12 to start moving, which will generate a large impact force. When stopping, there will also be an impact from braking. The damping spring 6 and the shock absorber 7 can buffer such impact forces.For example, the shock-absorbing spring 6 undergoes elastic deformation upon impact, absorbing and storing some energy, while the shock absorber 7 dissipates energy using its internal damping structure. Together, they make the starting and stopping process of the moving slide 12 smoother, avoiding strong vibrations caused by rigid impacts, thereby reducing noise transmission and keeping the moving slide 12 relatively quiet during both the start and end phases of operation. Especially in applications with frequent starts and stops, this buffering effect effectively reduces overall vibration and noise levels, improves the user experience, and also helps protect other equipment components. During operation, although precise components such as the lead screw 11 and linear guide 14 ensure linear motion, vibrations are inevitable due to various factors (such as microscopic surface unevenness of the linear guide 14, slight transmission fluctuations of the lead screw 11, and load changes). The damping spring 6 and damper 7 at the bottom act as vibration absorbers, continuously absorbing this vibration energy and preventing its transmission to the mounting base and surrounding environment. Furthermore, when the movable slide 12 bears loads of varying weights, its motion stability is affected to varying degrees. The presence of the damping spring 6 and damper 7 optimizes the movable slide 12's adaptability to load changes. The spring constant of the damping spring 6 can be reasonably selected according to the design load range of the movable slide 12, so that it can provide appropriate support and buffering effect when bearing different weight loads; the damper 7 can dynamically adjust the damping force according to the load change, so as to ensure that the movable slide 12 can still run smoothly under load changes, and will not have large vibration or displacement deviation due to sudden increase or decrease of load, further ensuring the stability and accuracy of the movement of the movable slide 12.
