Description

Technical Field

[0001] The utility model relates to the technical field of end face processing, in particular to an end face processing device used for manufacturing an intake valve. Background Art

[0002] In the production and manufacturing process of the intake valve, polishing and grinding its end face is a crucial step to ensure that the end face of the intake valve is flat, so as to have a high sealing performance when connected. However, there are some problems with the traditional method of polishing and grinding the end face of the intake valve. The traditional method is usually to polish and grind the end face of the intake valve by manually operating a polishing machine after the intake valve is fixed. This method is not only labor-intensive and inefficient, but also in the process of polishing and grinding, the dust particles produced by grinding are easily adhered to the polishing wheel, which is not easy to clean. This not only causes the end face of the intake valve to be affected by the dust particles, resulting in scratches, thereby reducing the end face quality of the intake valve, but also shortens the service life of the polishing wheel;

[0003] After searching, the applicant found that a Chinese patent disclosed "an end face processing device for intake valve manufacturing", and its publication (announcement) number is "CN215788667U". This patent mainly fixes a fixing block on the left side of the top of the base plate, and a clamping mechanism is installed on the right side of the fixing block, and two sets of limit parts are installed on the clamping mechanism, and connecting devices are installed on the front and rear sides of the clamping mechanism; the pushing mechanism is installed on the top of the base plate, and a grinding mechanism is installed on the left side of the pushing mechanism, but the fixing device of the device has no arc and is single, and there are problems such as unsatisfactory fixing effect and overheating during grinding. For this reason, we propose an end face processing device for intake valve manufacturing. Utility Model Content

The nozzle sprays water to remove heat through evaporation of the water, thereby protecting the end surface from heat damage. Some impurities such as cutting fluid, oil, and dust may remain on the end surface, and the nozzle can promptly remove these impurities to ensure grinding quality.

[0006] As a further solution of the present invention: the sliding groove is consistent in size with the guide post at the lower end of the L-plate, and the guide post is embedded in the sliding groove.

[0013] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model provides a reinforcement structure to firmly fix the intake valve, which can be adapted to intake valves of different sizes and specifications, so that the intake valve will not move or shake during the end surface processing. This is crucial to ensuring processing accuracy, because any slight movement may cause processing errors, which in turn affects the performance and quality of the intake valve. It ensures the accuracy and consistency of processes such as polishing and grinding. Operators can more conveniently install, fix and remove the intake valve, thereby saving a lot of time and labor costs. It works in conjunction with components such as the grinding wheel to achieve fast and efficient end surface processing, further improving production efficiency.

[0015] 2. The utility model is provided with a nozzle fixedly installed at the other end of the L-shaped support column. The water spraying from the nozzle can effectively reduce the temperature during the grinding process of the intake valve end face. During the polishing and grinding processes, the intake valve end face will generate a large amount of heat due to friction and cutting, which may cause defects such as deformation and cracks on the intake valve end face. The water spraying from the nozzle can take away the heat through the evaporation of water and protect it from heat damage. Some impurities such as cutting fluid, oil, dust, etc. may remain on the end face. The nozzle can remove these impurities in time to ensure the grinding quality.

[0016] Other advantages, objectives and features of the present invention will be described in part in the following description and will be apparent to those skilled in the art based on an examination of the following or may be learned from the practice of the present invention.
