Description

Technical Field

[0001] This utility model relates to the field of milling machine technology, specifically to a positioning fixture for a milling machine. Background Technology

[0002] Rolls are key equipment in industries such as metallurgy and papermaking. Their surfaces need to be precision machined to achieve the required dimensions and surface roughness. The design and manufacture of positioning fixtures are crucial to ensuring the machining quality of rolls. They work together to fix the rolls and ensure that they do not shift or rotate during the milling process.

[0003] Chinese patent publication number CN221019878U discloses a utility model that uses a telescopic rod to move a positioning fixture, thereby clamping and fixing the product. A drive motor moves the positioning frame in the front-back direction, adjusting the fixture's position. A pusher moves a sliding plate, adjusting its position in the left-right direction. This design offers the advantage of timely fixture positioning adjustment, avoiding inaccurate positioning and clamping during clamping, and allowing for continued adjustment even after the fixture has been positioned.

[0004] In actual operation, the aforementioned equipment demonstrated its excellent adjustability to the positioning device. Even after the positioning device is fixed, the equipment can still effectively fine-tune the product to ensure clamping stability. However, the clamping range of the equipment has certain limitations. Since products of different sizes are clamped using the same clamping blocks, the clamping effect achieved for products of different sizes will also vary. This difference is particularly noticeable in the subsequent milling process. When the equipment rotates, the friction generated may cause displacement of products that are not clamped stably. This displacement not only affects the processing accuracy of the product but may also lead to a decrease in the overall quality of the product. Optimization and improvement are needed.
