Description

Automobile door cover pressing cutter assembly with supporting effect

Technical Field

The utility model relates to the technical field of automobile door cover processing, in particular to an automobile door cover pressing cutter assembly with a supporting effect.

Background

At present, an automobile door cover is of an inner plate structure and an outer plate structure, as shown in fig. 1 and 2, the door cover needs to be covered during processing, and an outer plate is covered on the edge of an inner plate, so that the state of fig. 1 is changed into the state of fig. 2. At present, two main modes of edge wrapping of an inner plate and an outer plate of a door cover adopted in the automobile industry are as follows: and (5) edge pressing and edge rolling. The blank pressing refers to the traditional die blank covering, a press machine or an air cylinder is used for driving a pressing block to press the folded edges on the outer plate, and the inner plate is wrapped to achieve the purpose of assembly. The rolling edge is realized by adopting a roller (generally driven by a robot arm) to act on the folded edge, and the inner plate and the outer plate are pressed together by gradually folding for a plurality of times (generally 2-4 times) through plastic deformation of metal.

The utility model provides a need carry out the location with positioner to the work piece when binding, the utility model discloses a location clamp (CN 111250612A) of binding anchor clamps among the prior art, including clamp frame and locating support, be T type distribution on the clamp frame and install three locating support, it is equipped with the locating pin hole respectively to correspond the side that compresses tightly on two locating supports of symmetric distribution, correspond the side that compresses tightly on another locating support and be equipped with the locating piece, correspond the work piece locating pin that compresses tightly the side and be equipped with location inner panel work piece on the clamp frame, the clamp frame is fixed with a plurality of profile modeling briquetting along the periphery interval, the profile phase-match of the corresponding position that compresses tightly of each profile modeling briquetting, the clamp frame is installed the snatchs the subassembly of binding instrument for the opposite side that compresses tightly the side. During edging, the workpiece is buckled to the tire membrane to fix the outer plate, the robot grabs the positioning press tool to the workpiece, the inner plate of the workpiece is pressed by the profiling press block on the positioning press tool (the position of the outer plate cladding on the edge of the inner plate is reserved), then edging is carried out by the robot, and after edging is finished, the positioning press tool is lifted, and the profiling press block is withdrawn from the upper part.

The following technical problems exist in the profiling pressing block of the positioning pressing tool when the door cover shown in fig. 3 is rolled: because a hollow part is reserved between the inner plate and the outer plate of the finished door cover product, the profiling pressing block of the positioning pressing tool cannot extend into the hollow part to press the inner plate, if the inner plate is directly pressed outside the hollow part, the outer plate deforms due to the fact that the hollow part is not supported during edge rolling, and the product forming quality is affected, and therefore the profiling pressing block of the positioning pressing tool cannot be suitable for edge rolling of the door cover with the hollow part inside shown in fig. 3.

Preferably, as an improvement, the cutter body comprises a plurality of cutter blocks, and the cutter blocks are spliced end to form the cutter body.

The split type cutter pressing body is adopted, the cutter pressing blocks are spliced end to form the cutter pressing body, and compared with the integral type cutter pressing body, the cutter pressing body is more convenient to process, and can reduce processing residual materials and save material cost.

Preferably, as an improvement, a guide rail is fixed on the tool rest, the cross section of the guide rail is a dovetail shape, a sliding block is connected in the guide rail in a sliding way, and the sliding block is connected with a sliding block fixing seat.

During practical use, the sliding block is fixed on the binding positioning frame through the sliding block fixing seat, the sliding block is in sliding connection in the guide rail, and therefore sliding installation of the tool rest can be achieved, the tool rest is guided, and the structure is simple.

Preferably, as an improvement, a buffer mechanism is arranged on one side of the guide rail.

When the movable pressing knife is actually used, the buffer mechanism is arranged to buffer the sliding of the movable pressing knife, so that the sliding stability of the movable pressing knife can be improved.

Preferably, as an improvement, the buffer mechanism comprises a buffer seat fixed on the tool rest, and a buffer is connected between the front and rear of the buffer seat and the slider fixing seat.

In this scheme, because the movable pressing tool needs reciprocating motion, consequently all set up the buffer in the front and back of buffer seat (the front and back of movable pressing tool slip direction) and all cushion in reciprocating direction, the buffering effect is better.
