Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fine-tuning structure for polishing machine feed, and in particular to a fine-tuning structure for the feed of a piston rod polishing machine. Background Technology
[0002] In the manufacturing process of piston rods, polishing is a crucial precision machining step that directly determines the final quality of the product. Piston rods are widely used in core fields such as hydraulic and pneumatic equipment. Their surface roughness and precision not only affect the stability and sealing of equipment operation but also play a decisive role in the overall service life of the equipment. Currently, rotary contact polishing technology is commonly used. This involves a high-performance motor driving a fixture to precisely clamp the piston rod and rotate it at a set speed. Simultaneously, the polishing head is in close contact with the high-speed rotating piston rod surface. To ensure the high precision and stability of the polishing process, the fine-tuning structure for the polishing machine's feed plays an indispensable role. The fine-tuning structure for the polishing machine's feed is a device used to precisely control the feed amount of the polishing tool in the polishing machine. It can achieve minute displacement adjustments of the polishing tool to meet the polishing precision requirements of different processing techniques.
[0003] Existing piston rod polishing machines use a fine-tuning structure for feed adjustment. During operation, this often relies on a single cylinder to adjust the position of the polishing head. This method is inconvenient for stable fine-tuning of the polishing head. Firstly, the driving force output of a single cylinder is significantly affected by factors such as air pressure fluctuations and the stability of the air source. When there are slight changes in air pressure, the thrust and stroke control precision of the cylinder decrease, making it difficult for the polishing head to achieve stable and precise displacement during feeding. This easily leads to overfeeding or underfeeding, severely affecting the consistency of the polishing effect. Utility Model Content

[0027] Please see Figures 1-5 The present invention provides a fine-tuning structure for feeding a piston rod processing and polishing machine, including a polishing machine bracket 1.

The roller 382 and the frame plate 38 form a rotating structure through the rotating shaft 381. The roller 382 and the T-shaped guide plate 2 are movably connected.
[0029] By starting the stepper motor 31, the lead screw 32 can be rotated. Since the lead screw 32 is threadedly connected to the movable block 33 through the threaded groove 34, the movable block 33 can be moved, which in turn drives the receiving plate 35 to move. Under the action of the T-shaped guide groove 37, the slider 36 can slide stably along the T-shaped guide plate 2.

[0031] By activating the hydraulic rod 42, the receiving plate 43 can be moved, causing the guide rod 44 to slide stably along the support plate 41, thereby allowing the polishing head 45 installed at the bottom of the receiving plate 43 to be raised and lowered for adjustment.
