Description

Technical Field

[0001] The utility model relates to the technical field of piston rod processing, and particularly relates to a surface grinding device for piston rod processing. Background Technique

[0002] The processing of piston rods is a complex and delicate process, involving multiple steps and processes, and this process requires the use of a variety of machine tools and equipment, such as sawing machines, forging machines, lathes, milling machines, grinding machines, polishing machines, etc. With the development of technology, the application of numerical control machine tools in piston rod processing is becoming more and more extensive, and its characteristics of high precision and high efficiency make the processing process more stable and reliable.

[0003] A Chinese patent with the publication number CN218947149U discloses a piston rod end face processing device, which relates to the field of piston rod processing, including a grinding processing substrate. Both upper surfaces at the two ends of the grinding processing substrate are fixedly connected with end face processing boxes. End face grinding grooves are opened between the opposite inner surfaces of the two end face processing boxes. Driving motors are fixedly connected to the opposite outer surfaces of the two end face processing boxes through mounting connecting rods, and grinding discs are fixedly connected to the output shafts of the driving motors. By setting two grinding discs and adjusting studs in the utility model, the rotation of the adjusting studs enables the fixture connecting blocks, piston rod fixtures, and piston rods connected to the piston rod fixtures on the adjusting studs to move, come into contact with any one of the grinding discs, and achieve the synchronous polishing and grinding of the end and the outer surface, so as to reduce the processing time and improve the processing efficiency.

[0004] As described above, this patent provides a piston rod end face processing device, which can achieve the synchronous polishing and grinding of the end and the outer surface, so as to reduce the processing time and improve the processing efficiency. However, when grinding, the piston rod is not positioned at multiple positions, which leads to the piston rod being laterally deflected when grinding one surface and then grinding another surface, and then it is difficult to determine the verticality of the piston rod after grinding, and the overall processing efficiency still needs to be improved. Content of the Utility Model

[0011] The beneficial effects of adopting the above technical solutions are:

[0012] By setting up a grinding component, during operation, a placement chuck is used to place the piston rod. When placing, first open the placement top plate, then put in the piston rod, and later thread-mount the placement top plate into the mounting frame. The electric telescopic rod works to drive the locking chuck plate to move up and down, enabling the installation of piston rods of different lengths. When grinding later, to ensure the perpendicularity of grinding, four rotating card shafts are set. A grinding roller is fixed on the surface of each rotating card shaft, and a driven gear is fixed at the bottom end of the rotating card shaft. The placement chuck is connected to a transmission shaft, and a driving gear is fixed on the surface of the transmission shaft. When the transmission shaft rotates, it drives the driving gear to rotate.

Here, the four grinding rollers grind together, which can grind the surface of the piston rod from multiple angles and can also limit each surface of the piston rod, preventing the piston rod from deviating sideways during grinding and ensuring the perpendicularity of the piston rod, improving the grinding efficiency.

[0023] Through the above technical solution, the placing chuck 3 can rotate on the top of the workbench 1.
