Description

Flexible workstation that punches a hole of robot

Technical Field

The invention relates to the technical field of stamping equipment, in particular to a robot flexible punching workstation.

Background

The structural design of traditional car sub vehicle frame piercing press equipment is very complicated. The punching units are compactly connected into a whole through a mechanical structure, and the combination mode greatly improves the space utilization rate. However, the dense combination of multiple units is difficult to achieve in a desired range of size and weight, and the crowded structural design thereof has a great influence on manufacturing and maintenance repair.

Traditional car sub vehicle frame piercing press often can only compatible a product, can't realize the flexible switching of multi-vehicle type, increases enterprise's equipment, cost of labor, can not adapt to the big direction that manufacturing industry was new and old more and more frequently replaced now.

When the traditional punching machine debugs the punching precision quality again, the process is more complicated, a large amount of time is often spent to adjust a large number of parts, and the process is not favorable for timely position and precision adjustment.

When the parts of the punching unit of the traditional automobile auxiliary frame punching machine need to be replaced due to damage, the replacement steps are complicated due to the fact that too many assemblies are linked together, and the parts are prone to being neglected to be installed, lost and damaged by other intact parts in the replacement process. For example, when replacing some small and fragile parts, a plurality of punching unit devices need to be removed, and the hydraulic mechanism needs to be removed for replacement in individual cases. This makes the replacement of parts time consuming and serious, seriously affects production, and causes high economic loss to enterprise interests.

The punching units of the traditional punching machine for the auxiliary frame of the automobile are too compact in structure, and a plurality of equipment units need to be disassembled when equipment is maintained, so that a plurality of intact parts are repeatedly installed, the parts are abraded due to repeated installation of the parts, the service lives of the parts are shortened due to abrasion of the parts, and the like; and repeated installation spare part many times has great influence to the precision of spare part that punches a hole, can lead to the precision error increase of punching a hole, and the product of processing is unqualified, brings the mechanical and economic dual loss for the enterprise.

Because the traditional punching unit is too compact in structure, the punching equipment has higher requirements on hydraulic and pneumatic circuits. Because of the simultaneous action of clamping a plurality of devices or a plurality of punching unit pneumatic cylinders simultaneously, it is high to correspond gas station and hydraulic pressure station pressure requirement, and required hydraulic circuit and gas circuit are comparatively complicated, and this has also increased the degree of difficulty of assembly, dismantlement, is unfavorable for the change of spare part.

Because the punching unit structure of traditional piercing press equipment is complicated, and the equipment fault rate is higher relatively, the maintenance personal has very big inconvenience to the daily maintenance of equipment. Equipment is complicated, the structural connection degree is comparatively inseparable, and the workman has many blind areas when inspection, maintenance equipment.
