A high-efficiency and precise positioning vertical lathe combined fixture

Abstract

The invention discloses a high-efficiency and precise positioning vertical lathe combined fixture, specifically relates to the field of machine tool fixtures, including a base, two fixture bodies are arranged on the top of the base, assembly connecting plates are arranged on both sides of the fixture body, and the fixture An anti-rotation support frame is provided on the outside of the main body, a locking support frame is provided on one side of the anti-rotation support frame, a push slideway is provided at the connection between the base and the assembly connecting plate, a lifting ring is provided at the center of the base, and the two ends of the clamp body Both are provided with a centering positioning block, the centering positioning block and the inner wall of the fixture main body are provided with anti-slip protrusions, the centering positioning block is provided with a mounting hole, and a locking bolt is provided inside the mounting hole. The invention fixes the positions of the base and the fixture main body, locks the support of the support frame and the floating bar, facilitates the self-centering of the fixture main body, and avoids the angular rotation of the fixture main body on the base during the processing process, ensuring the clamping of the fixture. The stability is maintained, the time for alignment is saved, and the speed of product processing is improved.

Description

technical field [0001] The invention relates to the technical field of machine tool fixtures, more specifically, the invention relates to an efficient and precise positioning vertical lathe combined fixture. Background technique [0002] A machine tool fixture is a device on a machine tool used to clamp a workpiece and guide a tool. Refers to a fixture specially designed for a certain process of a certain workpiece. It is characterized by compact structure, fast, convenient and labor-saving operation, and can guarantee high machining accuracy and production efficiency, but the design and manufacturing cycle is long and the manufacturing cost is also high. When the product is changed, the jig will be scrapped because it can no longer be used. It is only suitable for production with fixed products and large batches. It is in contact with the positioning datum of the workpiece, and is used to determine the correct position of the workpiece in the fixture, so as to ensure the...

Problems solved by technology

Most of the existing mechanical processing is semi-finished product assembly and reprocessing. It is difficult to determine the product center. Generally, it needs to be aligned before processing. The separated products have high interchangeability requirements, which is not convenient for users to use.
