BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary jig with a frame for a vertically suspended surface-treating material to be treated. More specifically, it suspends a carrier bar while holding a plurality of materials to be treated. The present invention relates to an auxiliary jig with a frame that is suspended and supported by a jig.

[0002]

2. Description of the Related Art Conventionally, the work of attaching an untreated material for vertical suspension type surface treatment to a carrier bar is performed by attaching each material to be treated with a plurality of hanging jigs attached to the carrier bar. The method of framing is adopted. That is, as shown in FIGS. 6 and 7, the carrier bar 101
A hinge 103 is fitted and attached to a support metal fitting 102 having a pin-shaped cross-section having a bulging tip portion protrudingly provided on the lower surface of the base plate, and the upper end portion of the support plate body 105 of the hanging jig 104 is attached to the lower end portion of the hinge 103. It is attached. Hanging jig 104
Is composed of the support plate 105 and a pressing member 108 rotatably attached to a bracket 106 protruding from the support plate 105 via a shaft pin 107.
A file surface pressing portion 109 is provided on the inner side of the front end of 08, and the material A is sandwiched between the front ends of the support plate 105 and the pressing member 108 to press the support plate 105. The pressing member 109 at the tip of the pressing member is pressed against the material to be processed A by the spring member 110 which is hung and connected between the member 108 and the material to be processed A so that the material to be processed A is sandwiched and held. In addition, reference numeral 111 is a carrier bar (electrolysis frame) 1.
01 is an electrode contact portion for energizing the material A to be processed through the hanging jig 104. In this way, the hanging jig 10
The material A to be processed, which is suspended in a large number on the carrier bar 101 via 4, is conveyed in such a suspended state and is used in various processing tanks such as a degreasing tank, a water washing tank, an anodizing tank, and an electrolytic coloring tank. It is dipped and subjected to the desired surface treatment.

[0003]

By the way, in order to maintain the uniformity of the oxide film, the thickness of the coating film, the uniformity of the coloring, etc. in the surface treatment when the large and small size workpieces are simultaneously framed. , It is necessary to have an appropriate interval for the size (peripheral length, length, width) of the material to be processed, and therefore it is necessary to have a free pitch. As shown in FIG. 7, the framed carrier bar 101
Since each material to be processed is held by a hanging jig attached at a constant interval, it is difficult to frame the material to be processed at a free pitch.

Further, in order to improve productivity, it is desired to increase the number of materials to be framed on one carrier bar, but in the above-described conventional framing method, one suspension treatment is required. Since it is a method of suspending a single material to be processed, if you try to frame a large number of materials with this interval closed, on the contrary, various problems will occur due to sticking of the lower ends of the materials to be processed. . That is, when the material to be processed is subjected to the surface treatment by the vertical suspension method as described above, the lower end of the material to be processed is generally hung in a free state. Therefore, since a long material to be processed, particularly a long and slender material to be processed has a small weight, it does not vertically hang down with respect to the hanging jig when tilted by the hanging jig. Therefore, if the lower end contacts the lower end of the next material to be processed and is sent to the surface treatment step as it is, so-called sticking failure often occurs. Also, once sticking occurs between the materials to be processed, the lower ends of the materials to be processed are in contact with each other in a wet state, so that they do not separate in the subsequent processing process, and the inclination of the material to be processed in the frame attachment stage However, even if it is attempted to correct the above, there is no effect even if it is performed from below on the workpiece to be hung. Therefore, it is common practice to continuously finish the surface with the lower ends of the materials to be treated stuck to each other to make it a defective product, or to remove the film and reprocess it. It is a big problem in terms of cost and cost.

In order to meet the above-mentioned demands and solutions to problems, an auxiliary jig with a frame having a structure similar to that of a hanging jig is used, and a material to be processed which requires a relatively wide frame-to-frame interval in a carrier bar. The method is to attach a hanging jig at an interval that allows you to hang, and then attach an auxiliary jig with a frame that is set so that the material to be processed can be hung at a relatively narrow interval with a frame. Conceivable. That is, by using such a framed auxiliary jig, it is possible to deal with various framed intervals. However, when such an auxiliary jig with a frame is used, it is necessary to perform two operations of attaching and detaching the auxiliary jig with a frame to the hanging jig and attaching and detaching the material to be processed with respect to the auxiliary jig with a frame. There was a drawback that the work became complicated.

Therefore, a main object of the present invention is to provide a frame-assisting jig that is suspended and supported by a suspending jig of a carrier bar in a state where a plurality of materials to be processed are held in a fixed state. The vertical hanging type frame for surface-treating material that can simultaneously remove and attach the auxiliary jig with frame to the hanging jig and the workpiece to and from the auxiliary jig with frame by a single vise pressing operation. It is to provide an auxiliary jig. Another object of the present invention is to provide a frame-assisting jig for a vertically suspended surface-treating material to be treated, which can frame the material at a free pitch. Still another object of the present invention is to provide a frame-equipped auxiliary jig that allows a material to be processed to be hung vertically during framing, thereby preventing various troubles due to sticking of the lower ends of the material to be processed. It is in.

[0007]

In order to achieve the above-mentioned object, according to the present invention, with a frame that is suspended and supported by a suspending jig of a carrier bar in a state where a plurality of materials to be treated are held in a sandwiched manner. An auxiliary jig, which is a laterally slender plate-like held portion held by a hanging jig, a support portion projecting from the held portion, and a front-back direction on the support portion. The pressing body is rotatably attached to the shaft and its tip is biased toward the tip of the gripped portion. A vertically suspended type surface-treating material for surface treatment, which has a length such that the upper end of the pressing body is arranged at substantially the same position in height relationship as the upper end of the pressing member of the hanging jig when held by being held. An auxiliary jig with a frame is provided.

[0008]

The frame-assisting jig of the present invention is rotatably and axially rotatably supported on the support portion projecting from the gripped portion in the front-rear direction, and the tip of the jig extends toward the tip of the gripped portion. When the biased pressing body holds the held part of the framed auxiliary jig by the hanging jig, the upper end of the pressing body is approximately at the same height position as the upper end of the pressing member of the hanging jig. Has a length such as Therefore, the tip of the pressing body that holds the material to be processed of the auxiliary jig with a frame by one operation by simultaneously pressing the upper end of the pressing body of the auxiliary jig with a frame and the upper end of the pressing member of the hanging jig with a vise. The tip of the pressing member of the hanging jig and the tip of the support plate at the same time. The auxiliary jig with frame can be attached to and detached from the tool by a single vise pressing operation.

An auxiliary jig with a frame is a sheet-like held portion which is slender in the lateral direction and is held by a plurality of hanging jigs, and a support projecting from the held portion. When the pressing body is rotatably pivoted in the front-rear direction and has a single pressing body having a lateral width substantially equal to that of the held portion, or the pressing body has a predetermined interval in the longitudinal direction of the held portion. Even if a plurality of them are arranged apart from each other, if the pressing body of the auxiliary jig with a frame overlaps with the pressing member of the hanging jig in the lateral positional relationship, the frame is the same as above. It is possible to perform the attachment / detachment of the material to be processed with respect to the attachment auxiliary jig and the attachment / detachment of the frame-attached auxiliary jig with respect to the hanging jig by a single vise pressing operation.
On the other hand, in the case where a plurality of pressing bodies are arranged with a predetermined interval in the longitudinal direction of the held portion and are laterally displaced with respect to the pressing member of the hanging jig. Is
In addition to the single vise pressing operation described above, the vise pressing operation should be divided into two stages, and the pressing operation of the pressing body of the auxiliary jig with frame and the pressing operation of the pressing member of the hanging jig should be performed separately. By doing so, it is possible to remove only the material to be processed or only the framed auxiliary jig. Further, the pressing body tip portion of the frame-equipped auxiliary jig may be configured to be biased toward the held portion tip portion by a spring material,
Alternatively, a leaf spring is used as the pressing body, and its upper end is brought into contact with the upper end of the pressing member of the hanging jig and is pressed by a spring material that is provided so as to extend between it and the supporting plate of the hanging jig. The biasing force applied to the member can also be used.
