Description

Technical Field

[0001] The present invention relates to the technical field of metal processing, and relates to a turning and milling compound machine tool, and specifically relates to a turning and milling compound machine tool for metal processing. Background Art

[0002] Intelligent manufacturing equipment is a commonly used equipment in modern industrial production. Intelligent manufacturing equipment refers to manufacturing equipment with functions of perception, analysis, reasoning, decision-making, and control. It is the integration and deep integration of advanced manufacturing technology, information technology, and intelligent technology. Generally, it includes intelligent automated processing equipment such as robotic arms. In the process of producing intelligent equipment, a turning and milling compound machine tool is required to process and manufacture the components of the equipment.

[0003] When the existing turning and milling compound machine tool for metal processing is actually used, generally, a clamping jaw is used to clamp the metal. For softer metals, due to the relatively large clamping force of the clamping jaw, it is easy to damage the surface of the metal during clamping. Moreover, the chips generated during part processing are easily stuck on the clamping jaw, which in turn easily affects the clamping effect of the clamping jaw. And because there are chips on the clamping jaw, it is easy to scratch the surface of the metal when clamping the metal.

[0004] Therefore, it is urgent to improve the turning and milling compound machine tool for metal processing to solve the above existing problems. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a turning and milling compound machine tool for metal processing, which can replace the clamping jaw to clamp the metal part and will not scratch the surface of the metal part.

[0029] By setting the first hydraulic telescopic rod in the compound machine tool of the present invention, when the first hydraulic telescopic rod is started, it drives the air supply box to descend, and then can drive the airbag to approach the metal part to be processed. When the air pump is started, it drives air to be discharged into the air supply box and is transported to the airbag through the air supply box to make the airbag bulge, so as to clamp the metal part to be processed. Since the airbag is made of a relatively soft material, it is not easy to scratch the surface of the metal part. And by setting the first hydraulic telescopic rod, the position of the airbag can be adjusted to clamp metal parts to be processed with different sizes. By setting the protective sleeve, the first connecting plate, the limiting plate, and the protective cover, the chips generated during processing can be centrally collected, avoiding damage to the fixture caused by chip splashing during processing, and preventing the chips from splashing onto the airbag and puncturing the airbag.

By setting the second hydraulic telescopic rod, when the second hydraulic telescopic rod is started, it drives the extrusion block to rise to squeeze the debris in the collecting pipe, squeezing the debris into a cake, which can reduce the occupied area of the debris. By setting the fourth slider to be slidably connected with the fourth chute, the collecting pipe can slide on the first bottom plate. By setting the fourth slider as a T-shaped slider and cooperating with the T-shaped chute, the collecting pipe can be limited. By setting the fourth hydraulic telescopic rod, when the fourth hydraulic telescopic rod is started, it drives the first support seat to move, and then drives the protective sleeve and one of the first connecting plates to move, enabling the two first connecting plates to separate, which is convenient to clean the debris between the two first connecting plates and prevent the debris from jamming the limiting plate and causing the limiting plate to be unable to slide. By setting the fifth slider to be slidably connected with the fifth chute, the first support seat can be limited.
