Description

[Detailed Description of the Invention] The present invention relates to a jig for fixing a hanger used for surface treatment such as anodizing treatment to a transport frame, bus bar, etc.

Conventionally, when anodizing an aluminum product, as shown in Fig. 4, the object to be treated a is horizontally fixed to hangers c and c suspended from a transport frame b, and the transport frame b is placed in a surface treatment tank. A method has been adopted in which the object to be processed is transported to and subjected to the necessary processing on the object to be processed. However, simply hooking the hook parts d and d of the hangers c and c onto the transport frame b will cause vibrations during transport and shocks when the transport frame b is placed on the transport frame holder of the surface treatment tank.
Furthermore, due to buoyancy when the object a is put into the treatment liquid in the surface treatment layer, the hooks d and d are detached from the transport frame b, and the hangers c and c fall into the surface treatment tank, causing the object to be treated to fall into the surface treatment tank. Accidents such as damage to the surface treatment tank and damage to the surface treatment tank sometimes occurred.

For this reason, as shown in Fig. 5, the hook part d of the hanger c was fixed to the conveyor frame b using a shank vise e, but this method was difficult to attach and remove the shank vise e. It requires a lot of effort and has poor workability. In particular, when the hanger is long, such as 2 m or 3 m, it is necessary to attach and detach the vise e from a high place, making it difficult to ensure safety.

This invention was developed in view of the above circumstances, and allows the hook part of the hanger to be easily and reliably fixed to a transport frame or bus bar with one touch, and can be easily released with one touch, improving work efficiency. The purpose of the present invention is to provide a jig for fixing a surface treatment hanger.

That is, in order to achieve the above object, the present invention provides a jig for fixing a surface treatment hanger, which fixes a hook part of a surface treatment hanger to a body to be pressed by pinching the body to be pressed with the hook part of the surface treatment hanger. a jig body fixed to the jig body, an operating lever rotatably pivoted to the jig body, a cylindrical body movably attached to the jig body, and a cylindrical body fixed to one end of the cylindrical body. a link body having one end rotatably connected to the operating lever and a link body having the other end rotatably pivotally connected to the connecting body; A pressing body is inserted into the cylindrical body so as to be able to move in the axial direction while protruding from an end opening, and a coil spring is provided within the cylindrical body and interposed between the connecting body and the pressing body. By rotating the operating lever in a predetermined direction, the cylindrical body is advanced toward the pressed body through the link body and the connecting body, and the tip of the pressing body is brought into contact with the pressed body, and the coil spring is compressed. , the pressed body is pinched between the pressing body and the hook part of the hanger by the pressing force from the coil spring, and the operating lever is rotated in the opposite direction to the rotating direction, thereby the link body and the connecting body are Provided is a jig for fixing a surface treatment hanger, characterized in that the cylindrical body is withdrawn through the cylindrical body to release the pressed body from the pressed body between the pressing body and the hook portion of the hanger.

According to the surface treatment hanger fixing jig of the present invention, the pressing body presses the pressed object such as a conveyor frame or bus bar so that the pressing object is held between the tip pressing part of the pressing body and the hook part of the hanger. Therefore, the hook portion of the hanger is difficult to separate from the pressed object.
In this case, the pressing body is strongly pressed by the biasing force of the compressed coil spring, and therefore the pressing force of the pressing body on the pressed body is strong, so that the hook part is firmly fixed to the pressed body. At the same time, even if an impact is applied to the transport frame (for example, when the transport frame (the object to be pressed) is placed on the transport frame holder of the surface treatment tank, the impact force is absorbed by the coil spring and alleviated, so that the pressing object This prevents the hook from coming off the conveyance frame, and the pressing state of the conveyance frame by the pressing body is not released, so that the hook portion is always securely fixed to the conveyance frame.

Moreover, according to the present invention, fixing of the hook part using such a jig can be done by simply rotating the lever in a predetermined direction, and it can be done easily and reliably with one touch. The jig of the present invention has very good operability because it can be performed with one touch simply by rotating in the opposite direction to the above rotation direction.

Below, Figures 1 to 3 are shown for one embodiment of the present invention.
This will be explained with reference to the drawings.

1 in the figure is the main body of the jig for fixing the surface treatment hanger.
Two support plates 2 are installed at the bottom of one side of both sides,
2 is fixed. The tips of these support plates 2, 2 both protrude to the side of the jig main body 1, and one end of an operating lever 3 formed in a substantially L-shape is interposed between the protruding tips. One end of the lever 3 is pivotably attached to the protruding tips of the support plates 2, 2 by a pin 4.

5 is a tightening member, and this tightening member 5 is connected to a link body 6.
It is composed of a cylindrical body 7 and a pressing body 8. The link body 6 has an intermediate portion 2 that bulges laterally.
The intermediate corner of the substantially L-shaped lever 3 is interposed between one end of these long link plates 9, 9 with the other end protruding laterally. These link long plates 9, 9
One end of the lever 3 and the intermediate corner of the lever 3 are pivotably connected to each other by a pin 10. Further, the cylinder body 7 is inserted into a guide cylinder part 11 formed on one side upper part of the jig main body 1 so as to be movable in the axial direction, and one end of the connecting body 12 is inserted into the lower end opening of the cylinder body 7. A rod-shaped portion is inserted and fixed with a pin 13. The other end of this connecting body 12 is formed into a flat plate shape, and this other end plate-shaped part is interposed between the other end parts of the long link plates 9, 9, and the pins 14 are connected to the long link plates. The other end portions 9, 9 are pivotably connected to the other end plate-shaped portion of the connecting body 12. Further, the pressing body 8 has a rod-shaped portion 16 protruding from the lower end surface of the tip pressing portion 15, and this rod-shaped portion 16 causes the tip pressing portion 15 to protrude upward from the upper portion within the cylinder body 7. In addition to being inserted so as to be movable in the axial direction in the state,
A coil spring 17 is disposed within the cylindrical body 7 between the rod-shaped portion 16 of the pressing body 8 and the rod-shaped portion at one end of the connecting body 12.
is interposed, and the pressing body 8 is pressed upward by the urging force of the coil spring 17. Note that a guide slot 18 is formed in the upper part of the cylinder 7 along the axial direction.
is formed, and a protruding pin 19 protruding from the rod-shaped portion 16 of the pressing body 8 is inserted into this elongated hole 18, and this protruding pin 19 abuts and locks with the upper end wall of the elongated hole 18. The rod-shaped portion 16 is designed not to slip out from the cylindrical body 7. Further, the upper end surface of the tip pressing portion 15 of the pressing body 8 is formed as a minute unevenness portion 20 by knurling finishing.

The above-mentioned jig is used by inserting bolts 22, 22 into bolt insertion holes 21, 21 formed in the upper and lower parts of the other side of the jig main body 1, respectively, and fixing them at predetermined locations on the hanger 23. .
More specifically, when fixing the hook portion 24 of the hanger 23 to the conveyance frame (object to be pressed) 25, the jig is changed from the unfastened state shown in FIG. 3 to the fastened state shown in FIG. In this case, in the unfastened state shown in FIG. At the same time as being at the lower limit position, the pressing body 8 is also at the upper limit position where the protruding pin 19 is pressed upward by the spring 17 of the rod-shaped portion 16 and is locked in contact with the upper end wall of the elongated hole 18. When changing from this state to the tightening state shown in Figure 2, the third
Turn the protruding other end of the lever 3 in the state shown in the figure counterclockwise (in the direction of the arrow in the figure) in Figure 3 so that the intermediate corner of the lever 3 crosses the dead center and contacts one side wall of the jig main body 1. Rotate until it locks. As a result, the cylindrical body 7 of the tightening member 5 is connected to the jig main body 1 via the link body 6.
furthermore, after the tip pressing part 15 of the pressing body 8 comes into contact with the conveyance frame 25, the cylinder 7 rises until it reaches its upper limit position, and at the same time the pressing body 8 rises. The rod-shaped portion 16 advances into the cylinder 7 (the pressing body 8 relatively retreats), and the spring 17 is compressed.

Therefore, the pressing body 8 presses the conveyance frame 25 so that the conveyance frame 25 is sandwiched between its tip press part 15 and the hook part 24 of the hanger 23, and therefore the hook part 24 of the hanger 23 is removed from the conveyance frame 25. It is difficult to fall off. In this case, the pressing body 8 is strongly pressed by the biasing force of the compressed coil spring 17, and therefore the pressing force of the pressing body 8 on the transport frame 25 is strong, so that the hook portion 24 is pressed against the transport frame 25.
It is firmly fixed at 5. In addition, the compressed coil spring 17 presses the lever 3 downward via the connecting body 12 and the link body 6, so that the lever 3 is firmly fixed and the fixed state is not released inadvertently. Therefore, the tightened state of the jig is never released. Further, since the upper end surface of the tip pressing portion 15 of the pressing body 8 that comes into contact with the conveyance frame 25 is formed as a minute unevenness portion 20, the contact portion of the tip pressing portion 15 with respect to the conveyance frame 25 is prevented from shifting. At the same time, when placing the transport frame 25 on the transport frame holder of the surface treatment tank, etc.
Even if an impact is applied to the transport frame 25, the impact force is absorbed and relaxed by the coil spring 17, so that the pressing body 8 is prevented from coming off the conveyance frame 25.
Since the pressing state of the transport frame 25 by the pressing body 8 is not released, the hook portion 24 is always securely fixed to the transport frame 25.

Further, the hook portion 24 can be fixed using such a jig by simply rotating the lever 3, and can be easily and reliably fixed with one touch, resulting in very good operability. For this reason, the hanger 23 is long at 2 to 3 m, and even when the above-mentioned tightening operation is performed at a high place, it is easy to operate and there is less danger. and hold this ring part on lever 3.
Since the tightening operation can also be performed by hooking the other end and rotating it, it is possible to avoid work at high places.

Next, to release the tightened state shown in FIG. 2, the other end of the lever 3 is rotated clockwise in FIG. As a result, the cylindrical body 7 is lowered by being pulled by the link body 6 pivotally connected to the lever 3, and as it descends, the rod-shaped portion 16 of the pressing body 8 comes out of the cylindrical body 7, and the spring 17 is restored to its original state. After it is extended and the protruding pin 19 abuts and is locked against the upper end wall of the elongated hole 18, the pressing body 8 descends together with the descent of the cylinder 7, and the tip pressing part 15 of the pressing body 8 is released from the conveying frame 25. They are separated, and the tightening is released as shown in FIG. 3.

Therefore, this tightening release operation can be easily and reliably performed with a single touch by simply rotating the lever 3. Since it is easy to operate, there is less danger when working at heights, and the tip is shaped like a hook. Since the release operation can be performed by pulling down the other end of the lever 3 using a long rod, it is possible to avoid work at heights.

In addition, in the present invention, the tip pressing portion of the pressing body can be formed of rubber, thereby improving the adhesion to the pressed body and making it possible to insulate electricity from the pressed body. In this case, the entire pressing body may be made of a non-conductive material such as plastic or rubber, thereby ensuring the insulation effect. Furthermore, the shape of each component is not limited to the illustrated embodiment, and other configurations may be modified in various ways without departing from the gist of the present invention.

As explained above, according to the present invention, the hook portion of a hanger for surface treatment such as anodizing treatment can be easily and securely fixed to a transport frame, bus bar, etc. with one touch, improving work efficiency and improving work efficiency. This is a good way to reduce the dangers of working at heights.
