Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automobile body hood opening/closing jig used for opening and closing the hood by a robot in a robotized automobile body painting line.

[Prior Art] Conventionally, in an automobile body painting line, painting of the inside of a hood has been carried out with the hood opened upward (see, for example, Japanese Patent Laid-Open No. 62-30574).

In particular, when a robot is used to lift and lower (open and close) the hood, a jig as shown in FIG. 3 is used, for example.

Generally, a U-shaped hood lock striker is provided on the back surface of the tip of the hood 4 of an automobile body, and an opening 4 is formed between the two mounting portions of the hood lock striker. The conventional hood opening/closing jig shown in FIG. 3 includes a base member (21) that has a longer dimension than the opening and is inserted into the opening and locks both ends of the opening. a plurality of guide pins into which the hood lock striker is fitted; a limiting member that limits the descent of the hood 4 by coming into contact with a stopper provided at an appropriate position on the vehicle body when the hood prisoner is lowered; The stopper has an operating member (241) that is raised and lowered by a robot to open and close the radiator. This is an attached stopper member, etc.

That is, as described above, this conventional hood opening/closing jig is attached to the hood using the opening base and the hood lock striker shaft by the base member and the guide pin n, and the limiting member is attached to the hood using, for example, the aforementioned guide pin n. The hood 4 is paired with a stopper such as an abutment preventing member to prevent the hood from hitting during descent, and the parts operator robot locks the operating member (241) to open and close the hood 4.

However, since this type of jig is removed after painting the inside of the hood and reused repeatedly, the paint gradually becomes thicker on the jig. Therefore, the dimensions and shape of the base member and the guide pin n may change due to the thick coating of paint on the surface, making installation and removal difficult.
There is a problem in that the position of the operating member Q4 in the attached state is largely deviated from the initial fixed position, and the stability and reliability of locking the operating member (24) by the robot is impaired.

[Problem 8 to be solved by the invention] The present invention has been made in view of the above-mentioned problems with the conventional hood opening/closing jig for automobile bodies. To provide a hood opening/closing jig for an automobile body that can be easily installed and removed even in cases where the operation member is installed, and that the position of the operating member in the installed state is hardly displaced from the initial fixed position, and that only a small blemish is caused. The purpose is to provide

[Means for Solving the Problems] The present invention provides a U
A hood opening/closing jig that is installed using an opening formed between a letter-shaped hood lock striker and its two attachment parts, which has a longer dimension than the opening and is inserted into the opening. a base member that locks both ends of the opening, a clamping mechanism that clamps the hood lock striker, and a limiting member that limits the descent of the hood by coming into contact with a stopper provided at an appropriate position on the vehicle body when the hood is lowered;
It has an operating member that can be raised and lowered by a robot,
The clamping mechanism includes a fixed receiving member having a contact surface with which the hood lock striker contacts, a triangular plate rotatable around a rotation axis formed near one vertex, and the clamped hood lock striker. The present invention relates to an automobile body hood opening/closing jig comprising a pressing member that rotates a triangular plate in the direction of pressing it against a contact surface.

[Function] Since the jig of the present invention has a clamping mechanism consisting of the receiving member, the triangular plate, and the suppressing member, the interval between the receiving member and the triangular plate is equal to that of the hood lock striker. It is wide when fitting, and can be tightened when clamping, making installation and removal easy even when thick paint is applied.

Also, since the part that holds the hood lock striker is not exposed during painting, thick paint will not adhere there.
Combined with reliable fixation through tightening, the relative position of the jig to the hood lock striker can be accurately reproduced even during repeated use.

Furthermore, since the contact area between the jig and the food lock striker is small, there is less mold and mildew, which reduces the burden on post-processing.

[Example] Next, a hood opening/closing jig for an automobile body according to the present invention will be described based on an example shown in the drawings.

FIG. 1 is a perspective view showing an embodiment of the hood opening/closing jig of the present invention, and FIG. 2 is an enlarged side view of a clamping mechanism in the jig shown in FIG.

The hood opening/closing jig for an automobile body shown in FIG. 1 is similar to the conventional jig shown in FIG. It is attached to the hood using the opening formed between the attachment parts. The hood opening Ifff jig shown in FIG. 1 has a base member (1), a limiting member (3) and an operating member (4) similar to the conventional jig shown in FIG. A fixed receiving member (5) having a contact surface (5a) on which the hood lock striker contacts so as to be in contact with the hood lock striker, and a rotating wheel (5) formed near one vertex.
6a) A triangular plate (6) that is rotatable around the periphery, and a suppressing member (7) that rotates the triangular plate (6) in a direction to press the clamped hood lock striker against the contact surface (5a). It has a clamping mechanism (2).

The receiving member (5) is not particularly limited in its size, shape, and material as long as it has sufficient rigidity and provides a stable contact surface (5a).

The material and plate thickness of the triangle (6) are selected so as to provide sufficient rigidity to prevent deformation when pressed by the pressing member (7) against the clamped hood lock striker. The term "triangle" here includes triangles whose vertices are round and whose sides are not straight lines.

The reason why such a triangular shape is adopted is that it is easy to process and requires a minimum amount of processing, and that it has dimensions that provide sufficient rigidity and that it can minimize blemishes.

Note that the rotation shaft (6a) has an insertion hole formed with a tapped female thread in one of the triangular plate (6) and the receiving member (5), and a bolt to be screwed into the insertion hole is fixed to the other. This configuration is preferable in that it can minimize the accumulation of paint on sliding parts, and furthermore, the direction of the screw is such that when the triangular plate (6) rotates toward the abutting surface (5a), the bolt is It is particularly preferable to orient it in such a way that it loosens and comes out from the insertion hole, since it is less susceptible to the effects of adhering paint. In addition,
All operations are fixed and fastened in the direction of rotation.

Although the pressing member (sword) has a configuration consisting of a bolt and a nut in FIG. 2, it is not limited to this, and other configurations such as a wedge may be adopted. Pressure member (The movable parts of the sword are frequently moved before and after painting, so paint buildup is less likely to occur. However, in order to further limit paint adhesion and maintain smooth movement for a long time, it is necessary to press the movable parts during painting.) Preferably, a cover is used.

As mentioned above, a jig with such a configuration is easy to install and remove even when there is a thick coating of paint, and the relative position of the attached jig to the vehicle body can be maintained accurately even during repeated use. , only small shadows occur.

[Effects of the Invention] According to the present invention, even if paint is thickly attached to at least a portion due to repeated reuse, installation and removal can be easily performed, and the position of the operating member in the installed state can be adjusted. To provide a hood opening/closing jig for an automobile body which hardly displaces from an originally planned position and leaves only a small shadow.
