The utility model discloses a couple dress is hung on the cage back, and bracing piece on it supports and leans on the cage, plays stabilizing action to the couple of dress having hung the backplate down, and the work piece receives external force shake or removes the in-process, can not be because the aversion of couple and cage contact, avoided paint adhesion problem, greatly reduced the point rate of repairing, improved the production efficiency of spraying line.

Description

Hook for spraying lower protective plate of automobile door

Technical Field

The utility model relates to a frock is used in the spraying, concretely relates to backplate couple is used in spraying under car door.

Background

When the lower protective plate of the automobile door is coated, a hook is usually required to be used for assisting coating, one end of the hook penetrates through an assembly hole in the lower protective plate of the automobile door, the other end of the hook is hung on a suspension cage, and then spraying operation is started.

In the actual spraying operation, through the work position feedback is examined to the lamp of next part, the bad phenomenon of finish often appears in the backplate under the door, including sagging, the end of revealing, granule, virtual rifle, colour difference, paint adhesion scheduling problem, through stage statistics, the rate of returning the production line reaches 60.6%, and wherein the adhesion problem accounts for 84% in the piece of returning the production line, if can solve the adhesion problem, just can greatly reduced rate of returning the production line, improve the production efficiency of spraying line. The main reason for the adhesion is that the hanger is not targeted, resulting in direct contact between the work piece and the cage. To ordinary hanger, the backplate dress hangs the back under the door, and in chain operation, the work piece has the shake phenomenon, and the work piece corner can contact and paint adhesion with the cage.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a couple is used in backplate spraying under with low costs, simple structure's the car door is provided.

The technical scheme for realizing the purpose of the utility model is that the hook for spraying the lower guard plate of the automobile door comprises a suspension cage hook, a lower guard plate hook, a connecting rod and a supporting rod, wherein the suspension cage hook, the lower guard plate hook and the connecting rod form a hook main body; the bracing piece is fixed in the junction of cage hook and connecting rod, and the bracing piece is perpendicular with the connecting rod.

The hook main body is formed by bending and molding two ends of a metal rod.

The shape of the cage hook is U-shaped, and the shape of the lower guard plate hook is U-shaped or V-shaped.

The utility model discloses has positive effect: the utility model discloses a couple dress is hung on the cage back, and bracing piece on it supports and leans on the cage, plays stabilizing action to the couple of dress having hung the backplate down, and the work piece receives external force shake or removes the in-process, can not be because the aversion of couple and cage contact, avoided paint adhesion problem, greatly reduced the point rate of repairing, improved the production efficiency of spraying line.

Drawings

Fig. 1 is a schematic structural view of the hook of the present invention;

the reference numbers in the above figures are as follows: a suspension cage hook 1, a lower guard plate hook 2, a connecting rod 3 and a support rod 4.

Detailed Description

(example 1)

See fig. 1, the couple for backplate spraying under car door of this embodiment includes cage hook 1, backplate hook 2, connecting rod 3 and bracing piece 4 down, and wherein the couple main part is constituteed to cage hook 1, backplate hook 2 and connecting rod 3 down, and the couple main part is an organic piece, and bracing piece 4 is fixed in the couple main part. The hook body in this embodiment is obtained by bending and molding a metal rod into two ends in the shape of fig. 1.

The cage hook 1 and the lower guard plate hook 2 are respectively arranged at two ends of the connecting rod 3, the cage hook 1 is U-shaped, the lower guard plate hook 2 is U-shaped or V-shaped (U-shaped in figure 1), and the opening directions of the cage hook 1 and the lower guard plate hook 2 are opposite, namely, as shown in figure 1, the opening of the cage hook 1 faces downwards, and the opening of the lower guard plate hook 2 faces upwards. The length of the connecting rod 3 is to be guaranteed: the lower guard plate is hung on the hook and is hung on the suspension cage, and the lower guard plate cannot contact with the suspension cage surface.

The support rod 4 is welded and fixed at the joint of the suspension cage hook 1 and the connecting rod 3. The support rod 4 is perpendicular to the connecting rod 3.

During the use, with car door backplate spraying with cage hook 1 dress of couple hang in the net of cage, bracing piece 4 supports and leans on the cage surface this moment, and the acute angle of the contained angle of connecting rod 3 and cage face is 75 ~ 90 (90 under the backplate hook 2 and cage distance are the farthest). Hang the backplate under the door on backplate hook 2 under through its pilot hole dress, the backplate can not contact the cage surface under the door, because bracing piece 4 receives external force shake or removal in-process at the support stabilizing effect of cage face at the work piece, can not because cage hook 1's aversion and with the cage contact, avoided paint adhesion problem, greatly reduced the point rate of repairing, improved the production efficiency of spraying line.
