Abstract
Description
Technical Field
[0001] This utility model relates to the field of gear hobbing technology, and in particular to a shock absorption and buffer device for a horizontal CNC gear hobbing machine. Background Technology
[0002] During the operation of a horizontal CNC gear hobbing machine, vibration control is a key link to ensure gear machining accuracy and extend the service life of the equipment. As the core structure for absorbing vibration energy, the performance of the shock absorption buffer device directly affects the working stability of the gear hobbing machine. Among them, whether the buffering force of the adjusting spring can adapt to the vibration intensity under different working conditions is an important factor in determining the shock absorption effect.
[0003] Traditional horizontal CNC gear hobbing machines have significant limitations in their vibration damping devices: the preload of the adjusting spring is fixed during installation, lacking a flexible adjustment mechanism. Due to the large differences in the specifications and materials of the gears processed by the gear hobbing machine, the resulting vibration intensity varies significantly—vibration is severe when processing large or hard material gears, requiring strong damping force; vibration is gentle when processing small or soft material gears, and excessive damping force can reduce the flexibility of the equipment and even affect the processing accuracy. Therefore, these problems need to be solved. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example: See Figure 1-4 This utility model discloses a shock-absorbing and buffering device for a horizontal CNC gear hobbing machine, comprising a cabinet 2, with a cover plate 1 hinged to the top of the cabinet 2. The cover plate 1 effectively blocks external dust and impurities from entering the interior of the cabinet 2, protecting the shock-absorbing and buffering device and the gear hobbing machine components. A glass window is embedded in the side wall of the cover plate 1. Buffer components are provided at the four corners inside the cabinet 2, and connecting blocks are fixed to the top of the buffer components. Adjustment components are easily installed through the connecting blocks. Adjustment components for adjusting the height of the gear hobbing machine are provided at the bottom of the connecting blocks, and fixing bolts 3 are provided at the four corners of the top of the connecting blocks for fixing to the cabinet 2. The fixing bolts 3 ensure that the connecting blocks are firmly connected to the cabinet 2, preventing the buffer components from shifting due to vibration during operation.
[0020] In this utility model, the buffer component includes four damping shock absorbers 5 located at the four corners inside the cabinet 2. An adjusting ring 11 is threadedly connected to the middle of each damping shock absorber 5, and an adjusting spring 10 is installed on the top of the adjusting ring 11. An installation block 12 is provided at the bottom of each damping shock absorber 5. The buffer component facilitates the absorption of vibration energy, effectively reducing vibration intensity, and allows for adjustment of the connection hole position to optimize the buffer stroke and prevent excessive compression damage to the spring. A threaded post 13 is threadedly connected to the installation block 12, and a connection hole is provided at the top of the threaded post 13. A damping shock absorber spring 7 is installed in the connection hole, and the bottom of the damping shock absorber 5 slides within the connection hole. The bottom end face of the damping shock absorber 5 is fixedly connected to the top of the damping shock absorber spring 7. The threaded post 13 allows for easy adjustment of its height within the installation block 12, thereby changing the position of the connection hole. The adjustment component includes a base 4 fixed to the bottom of the cabinet 2. Two mounting slots are symmetrically provided on the base 4, and two bidirectional damping springs are installed in the two mounting slots. The machine is equipped with two double-acting lead screws, each with a first adjusting member 8 and a second adjusting member 9 threaded to its ends. The top of the first adjusting member 8 is hinged to a first connecting rod, and the other end of the first connecting rod is hinged to a first support plate for lifting the gear hobbing machine. The top of the second adjusting member 9 is hinged to a second connecting rod, and the other end of the second connecting rod is hinged to a second support plate for supporting the lifting operation. These adjusting components facilitate stable adjustment of the overall height of the gear hobbing machine, and allow for individual adjustment of the height at both ends to ensure the machine is horizontal or at the desired tilt angle. A rotating bearing is provided at the connection between the double-acting lead screw and the mounting groove. A knob 6 is fixed to one end of the double-acting lead screw, allowing for easy adjustment of the gear hobbing machine's height. The adjustment ring 11 has a circular structure with anti-slip grooves on its outer side for easy manual rotation. The adjustment ring 11 allows for easy movement up and down along the damping column 5, changing the preload of the adjusting spring 10.
[0021] Working Principle: In use of this utility model, firstly, each electrical component in this application is connected to the power supply. Then, the adjusting component uses the chassis 4 as the mounting base, and the height of the gear hobbing machine is flexibly adjusted by rotating the bidirectional lead screw. When the height of the gear hobbing machine needs to be adjusted, the operator rotates the knob 6 at one end of the bidirectional lead screw. With the support of the rotating bearing, the bidirectional lead screw rotates smoothly in the mounting groove of the chassis 4. Since the first adjusting component 8 and the second adjusting component 9 are respectively threaded to both ends of the bidirectional lead screw, and the thread directions are opposite, when the bidirectional lead screw rotates, the two will slide synchronously in opposite directions along the mounting groove. Then, when the first adjusting component 8 slides, it drives the first connecting rod at the top hinge to change the tilt angle, thereby pushing the first support plate to rise or fall. Similarly, the second adjusting component 9 drives the second support plate to adjust its height synchronously through the second connecting rod. Through this linkage mechanism, the first support plate and the second support plate jointly support the gear hobbing machine, realizing the smooth adjustment of its overall height. The height difference between the two ends of the gear hobbing machine can also be adjusted by precisely controlling the rotation angle of the knob 6 to ensure that the equipment is in a horizontal working state or meets a specific processing angle. The demand is that, then, the buffer components are distributed at the four corners inside the cabinet 2. They absorb the vibration generated by the operation of the gear hobbing machine through the elastic deformation of the springs. When the gear hobbing machine vibrates, the vibration energy is transferred to the connecting block, which in turn drives the damping column 5 to move downward. The bottom of the damping column 5 slides along the connecting hole of the threaded column 13, compressing the damping buffer spring 7 in the connecting hole. At the same time, the adjusting ring 11 in the middle of the damping column 5 squeezes the adjusting spring 10 at the top. The two springs undergo elastic deformation synchronously, converting the kinetic energy of the vibration into elastic potential energy, realizing the first stage of vibration. Dynamic attenuation: When the vibration weakens, the damping buffer spring 7 and the adjusting spring 10 release elastic potential energy, pushing the damping shock absorber column 5 to return to its original position, thus preventing the vibration energy from being directly transmitted to the cabinet 2. In addition, by rotating the adjusting ring 11, the compression of the adjusting spring 10 can be changed, and its preload can be adjusted. Rotating the threaded column 13 can change the height of the connecting hole in the mounting block 12, optimizing the buffer stroke, so that the buffer components can be flexibly adapted according to the vibration intensity of the gear hobbing machine, ensuring a stable and reliable shock absorption effect. This concludes the use of the shock absorption buffer device for the horizontal CNC gear hobbing machine.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
