Description

A kind of self-adaptive and universal car fender material frame and self-adaptive support method

technical field

The invention relates to a material rack, in particular to an adaptive and universal automobile fender material rack and an adaptive supporting method.

Background technique

The fender is the outer panel of the car body that covers the wheels. It is named after the shape and position of the part on the old car body like a bird's wing. According to the installation position, it is divided into front fender and rear fender. The front fender is installed at the front wheel. It is necessary to ensure the maximum limit space when the front wheel rotates and jumps. Therefore, the designer will use the "wheel jump diagram" to verify whether the design size of the fender is appropriate according to the selected tire model size.

The fender is a sheet metal part, which requires a special rack to store it. The car fender is limited by the upper limit rod, front limit rod, and rear limit rod to ensure that it maintains a specific shape. There are following deficiencies in the existing fender sheet material rack:

Since the parts of the fenders have different shapes, different or material racks need to be designed for specific parts, that is, each type of fender corresponds to a special material rack, which is not only poor in flexibility and versatility, but also after the specifications of the fenders are changed, the raw material racks are not applicable, so they can only be discarded and re-produced, wasting manpower and material resources.

The upper pressing mechanism includes an overturning swing arm, an upper turret and an upper locking structure for locking the upper turret after the upper turret is pressed on the fender; both ends of the overturning swing arm are respectively connected to the frame and the upper turret in rotation; the upper turret is provided with two pressing rods for pressing different sides of the fender respectively.

The working principle of the above-mentioned self-adaptive and universal automobile fender sheet rack is as follows:

During work, the upper turret and the lower turret are unlocked respectively through the upper locking structure and the lower locking structure; the upper turret is turned up by turning the swing arm to avoid placing the fenders; at this time, the lower turret is in a free state of arbitrary rotation.

A corner is provided at one of the corners of the inner concave arc surface of the fender to be placed close to the wheel, and a downwardly convex screw mounting part is also provided at the corner. When placing the fender for the first time, take the corner of the fender as a reference, and place it on the outer lower support structure of the lower turret of one group of adaptive brackets. At the same time, the lower turret of another group of adaptive brackets also adaptively adjusts its posture under the extrusion of the inner concave arc surface of the fender to complete the support. The lower turret is locked by the lower locking structure, so that the lower turret maintains the current posture; when placing other fenders of the same specification, the fenders are mounted on the two lower turrets, so that the corners of the fenders are located on the above-mentioned lower support structure corresponding to the reference, so as to ensure that the postures of all the placed fenders are consistent. Further, since the fender is a sheet-shaped part, when the fender is placed, the corresponding position of the fender is snapped into the position-limiting slot of the lower support structure, so that it can be limited.

After the fenders are placed on the lower turret, the upper turret is turned down by turning the swing arm, and the attitude of the upper turret is adjusted by turning, so that the two pressure bars of the upper turret are respectively pressed on the two sides of the fenders, and then the upper turret is locked by the upper locking structure, so as to fix all the fenders so as not to fall off during the movement.

Further, when it is necessary to place other fenders of different specifications, follow the above operation to unlock first, initialize the state of the lower turret, and then lock and place fenders of other specifications after the lower turret adaptively adjusts its attitude.

In a preferred solution of the present invention, the lower support structure includes a support rod and a limiter set, the support rod is fixed on the lower turret; the limiter set is coaxially sleeved on the support rod, and a plurality of limit placement slots are provided on the limiter set.

Further, the limit kit is axially movably connected to the support rod, so that the relative positions of the limit slots can be adjusted according to the structure of the fender to adapt to different fenders.

Further, the lower support mechanism of the upper receiving mechanism also includes a flip avoiding arm and a lower locking structure for locking the flip avoiding arm; the flip avoiding arm is rotatably connected to the frame; the two lower turrets corresponding to the flip avoiding arm are rotatably connected to the flip avoiding arm. Through the above structure, the fenders are placed in order from bottom to top, and the upper lower turret is turned up by turning the avoiding arm, so as to avoid the fenders from being placed on the lower support mechanism below, so that more receiving mechanisms can be arranged on the frame with limited height to improve the loading capacity.

A self-adaptive support method for a self-adaptive general automobile fender sheet rack, comprising the following steps:

The locking of the upper turret and the lower turret are respectively released by the upper locking structure and the lower locking structure; the upper turret is turned up by turning over the swing arm to avoid the placement of the fender; at this time, the lower turret is in a free state of arbitrary rotation; a corner is provided at one of the corners of the inner concave arc surface of the fender to be placed, and the corner is also provided with a convex screw mounting part;

When placing the fender for the first time, take the corner of the fender as the reference, and place it on the outer lower support structure of the lower turret of one group of self-adaptive brackets.

At the same time, the lower turret of another group of adaptive brackets also adaptively adjusts its own posture under the extrusion of the concave arc surface of the fender to complete the support;

The lower turret is locked by the lower locking structure, so that the lower turret maintains the current posture; when placing other fenders of the same specification, the fenders are placed on the two lower turrets, so that the corners of the fenders are located on the lower supporting structure corresponding to the reference above, so as to ensure that the postures of all the placed fenders are consistent;

After the fenders are placed on the lower turret, the upper turret is turned down by turning the swing arm, and the posture of the upper turret is adjusted by turning, so that the two pressure bars of the upper turret are respectively pressed on the two sides of the fender, and then the upper turret is locked by the upper locking structure, thereby fixing all the fenders.

In a preferred solution of the present invention, when other fenders of different specifications need to be placed, according to the above operation, the lock is first released, and the state of the lower turret is initialized. After the lower turret self-adaptively adjusts its attitude, it locks and accommodates fenders of other specifications.
