Technical Field
[0001] This utility model relates to the field of gear processing technology, and in particular to a vibration damping device for processing automotive engine gears. Background Technology
[0002] As one of the key components of a car engine, the quality and precision of automotive engine gears play a crucial role in the engine's performance and stability. During the machining process of automotive engine gears, cutting operations are usually required. Due to the enormous cutting force, the gears will experience strong impacts and vibrations. In order to reduce the impact of vibration on machining accuracy and quality, vibration damping measures are usually required for the gears.
[0003] Existing technologies, such as Chinese Patent Publication No. CN222885953U, disclose a vibration damping device for machining automotive engine gears, including a base and a gear placement platform. First damping mechanisms are connected between the four corners of the upper surface of the base and the gear placement platform. Second damping mechanisms, arranged in a cross shape, are matched and connected between the base and the bottom surface of the gear placement platform. A clamping assembly for clamping and fixing the gear is fixedly installed at the center of the upper surface of the gear placement platform. This invention, by setting the first damping mechanism and the cross-shaped second damping mechanism between the base and the gear placement platform, can effectively absorb and reduce the huge impact force and vibration generated during the cutting process, reducing machining errors caused by vibration. The inner ring of the gear is sleeved outside the clamping assembly. The design of the bidirectional lead screw and slider in the clamping assembly allows the fastening block to evenly clamp and fix the gear from the inner ring outwards, avoiding the gear eccentric movement problem caused by the traditional method of tightening from top to bottom with a nut. However, the vibration damping structure of this utility model is exposed, and dust and debris generated during gear processing may enter the structure, affecting the vibration damping effect or damaging the vibration damping components. In addition, the spring is not easy to maintain and replace, and the buffering effect deteriorates after long-term use, resulting in insufficient overall durability.
[0004] To address the issue that vibration damping devices used in automotive engine gear machining are easily damaged or have their damping effect affected by dust and debris generated during machining, existing equipment often exposes the damping structure directly during gear machining. This results in dust and debris generating during machining damaging the structure or affecting the damping effect. A few additional protective mechanisms are added around the damping structure, but this increases equipment costs, and the protective mechanisms are also prone to damage under continuous vibration. Therefore, improvements are needed. Utility Model Content
[0005] The purpose of this invention is to solve the problem that existing vibration damping devices used in automotive engine gear processing are easily damaged or have their vibration damping effect affected by dust and debris generated during processing. Therefore, this invention proposes a vibration damping device for automotive engine gear processing.

There are two sets of telescopic rods. There are four sets of buffer grooves, springs, push plates, push rods, hemispherical blocks and receiving grooves.

[0014] Furthermore, a knob is fixedly connected to the surface of the screw, and the surface of the knob is provided with anti-slip texture. The anti-slip texture consists of multiple sets and is evenly distributed around the circumference.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] 1. In this utility model, by setting a vibration damping mechanism, when the processing table vibrates vertically along the slide groove, it squeezes the hemispherical block and causes the push rod to drive the push plate to slide along the buffer groove. The vibration is buffered by a damping system composed of a spring, push plate, push rod, and buffer groove. The vibration damping mechanism is sealed to prevent processing dust and debris from entering and affecting the vibration damping effect. When it is necessary to disassemble the spring for maintenance or replacement or to adjust the spring's elasticity, simply turn the knob to move the screw away from the insertion rod along the screw hole, so that the screw is disengaged from the positioning hole. Then, the insertion rod can be pulled out of the slot to maintain or replace the spring. After that, reinsert the insertion rod into the slot, observe the scale line, and move the insertion rod to an appropriate position in the buffer groove to squeeze the spring to an appropriate degree, thereby adjusting the spring's elasticity. Then, reverse the knob to insert the screw into the corresponding positioning hole to fix the insertion rod.

The whole is sealed to prevent processing dust and debris from entering and affecting the vibration damping effect. At the same time, it is also convenient to maintain and replace the springs or adjust the elasticity of the springs, thus effectively improving the durability of the equipment.
