Description

Technical Field

[0001] The utility model relates to the technical field of gear grinding devices, and specifically refers to a gear grinding device for vehicle engines. Background Art

[0002] In modern automotive industry, vehicle engine gears are crucial transmission components in the engine system, and their performance and quality directly affect the working efficiency and stability of the engine. Engine gears usually need to have high precision, high strength, and good wear resistance to ensure reliable transmission under high-speed operation and complex working conditions.

[0003] In order to ensure the good performance of vehicle engine gears, fine grinding of their end faces is an essential processing step. However, there are many defects in traditional vehicle engine gear grinding devices.

[0004] In terms of gear clamping and fixing, traditional grinding devices often cannot provide a stable and reliable clamping. Due to insufficient clamping force or unreasonable clamping method, the gear is prone to displacement and shaking during the grinding process, which not only seriously affects the grinding precision and quality, but also may cause uneven grinding of the gear end face, and even damage the gear. Unstable clamping and fixing will also increase the rejection rate, raise production costs, reduce production efficiency, and cannot meet the requirements of modern automotive industry for high-quality, high-precision, and high-efficiency production.

[0028] Reference appendix Figure 2 , the grinding assembly includes an electric push rod 11 fixedly arranged on the upper end of the support plate 2. The piston end of the electric push rod 11 extends into the lower end of the support plate 2 and is fixedly provided with a U-shaped bracket 12.

[0032] The gear grinding device for the vehicle engine achieves precise grinding of the gear through the following synergistic effects: The bidirectional drive mechanism can flexibly adjust the position of the gear clamping assembly according to gears of different sizes, thereby achieving precise, stable and reliable clamping. The ingenious cooperation of the guide rod, slider and spring endows the clamping with a certain elastic buffering function, enabling the gear fixing post to have a certain range of elastic adaptive adjustment ability. This design effectively avoids clamping damage to the gear caused by excessive clamping force or size mismatch. At the same time, the limiting mechanism can further fix the slider to prevent the gear fixing post that holds the gear from shifting, ensuring that the gear always remains stable during the grinding process. The electric suction cup on the gear placement table further enhances the fixing effect on the gear, greatly reducing the error caused by gear shaking, thereby greatly improving the grinding accuracy and quality.

[0033] Before the utility model is used, an external power supply is first connected, and its working process is described as follows:

[0034] First, place the vehicle engine gear to be ground steadily at the central position of the gear placement table 3, and turn on the electric suction cup 22 to generate a strong suction force to tightly adsorb the bottom surface of the gear, providing basic stable support for the gear.

[0035] Then, according to the actual size of the gear, manually rotate the runner 18 of the bidirectional drive mechanism. The rotation of the runner drives the bidirectional lead screw 16 to start operating, causing the two sleeve blocks 17 to move towards or away from each other as required in the groove 15, and then driving the moving block 5 to accurately move to the appropriate position. The slider 8 on the moving block 5 gently contacts the side surface of the gear under the elastic action of the spring 9. After adjusting the general position, tighten the fixing bolt 19, and use the pressing plate 20 to firmly squeeze and fix the slider 8 to ensure that the gear is clamped safely and reliably.

[0036] Next, start the electric push rod 11, and its piston end slowly extends, driving the U-shaped bracket 12 and the grinding sand belt 13 to descend until the grinding sand belt 13 accurately contacts the end surface of the gear.

[0037] Finally, start the motor 14, and the motor drives the grinding sand belt to rotate at a high speed and stably, and start to finely grind the end surface of the gear. During the grinding process, the operator can flexibly fine-tune the extension length of the electric push rod according to the real-time grinding situation to obtain the best grinding effect.

[0038] After the grinding operation is completed, turn off the motor, electric push rod and electric suction cup in sequence, loosen the fixing bolt, and carefully take out the ground gear.
