Description

Technical Field

[0001] This utility model belongs to the field of workpiece processing technology, and in particular relates to horizontal machining centers. Background Technology

[0002] Horizontal machining centers are commonly used in the aerospace, automotive and other fields for machining complex parts, and can perform a variety of machining methods such as turning and milling.

[0003] However, in existing horizontal machining centers, the continuous contact between the cutting tool and the workpiece during machining will cause a certain degree of wear, especially after long-term use. Wear such as notches will appear on the tool surface, which will greatly affect the machining accuracy of the workpiece. The efficiency of tool replacement in horizontal machining centers is low. It generally requires multiple steps to complete the replacement, and the operation is cumbersome and time-consuming, which makes it difficult to meet the needs of modern manufacturing for high-efficiency production. Therefore, we propose the horizontal machining center. Utility Model Content

[0004] The purpose of this utility model is to provide a horizontal machining center that, by setting up a tool changing mechanism, specifically by turning a rotating ring clockwise, causes the rotating ring to move outward via a moving column, thereby releasing the tool from the restriction of the tool. The operation is clear and the steps are simple, greatly improving the tool changing efficiency and reducing the impact of tool changing on production. It solves the problem that existing horizontal machining centers have low tool changing efficiency, generally requiring multiple steps to complete the change, and are cumbersome and time-consuming, making it difficult to meet the needs of modern manufacturing for high-efficiency production.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

Afterwards, surface wear will seriously affect the processing effect, and it needs to be replaced. Open the side door and turn the rotating ring 311 clockwise. The rotating ring 311 drives the moving column 323 to move inward and outward through the internal arc groove. The moving column 323 drives the retaining strip 322 to move outward. The retaining strip 322 compresses the spring 321. The spring 321 accumulates elastic force. When the retaining strip 322 no longer holds the tool 312, pull out the tool 312, take out a new tool 312, align it with the inside of the mounting shaft 313 and insert it.

After it is fully inserted, the retaining strip 322 will be bounced back to its original position by the elastic force accumulated by the spring 321 to limit the tool 312. At this time, the replacement is completed.
