Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting jig for mounting a workpiece in metal surface treatment such as alumite processing and electrolytic polishing to a racking jig for an electrolytic frame.

[Conventional technology]

Generally, when performing metal surface treatments such as alumite processing or electrolytic polishing, an electrolytic frame with a large number of materials to be treated vertically suspended is transported to each treatment tank using a transportation device such as a crane, and the materials to be treated are immersed in a designated treatment liquid tank. A predetermined surface treatment is performed.

In this way, as a jig for attaching a large number of materials to be treated in a vertically suspended state to an electrolytic frame, for example, Jikkosho's
The one shown in Japanese Patent No. 61-20037 is known.

That is, as shown in FIG. 7, a groove 4 is formed in the side surface of the main body 3 having a holding piece 2 that is clamped by a racking jig 1 attached to the electrolytic frame, and a holding plate 5 is connected with a bolt 6. , this presser plate 5 and groove 4
A jig is known in which a workpiece 7 is inserted between the workpiece 7 and the workpiece 7 and the workpiece 7 is held by a presser plate 5 by tightening a bolt 6.

[Problem that the invention attempts to solve]

With such a jig, it is possible to grip and mount multiple materials to be treated, and also to clamp them with a single racking jig and mount them vertically on the electrolytic frame. The workpiece 7 must be gripped and released by the presser plate 5, which makes the operation very troublesome, and the unprocessed workpiece 7 must be gripped by the tightening force of the bolt 6. As a result, a large force commensurate with the gripping force acts on the threaded portion of the bolt 6, causing early damage to the threaded portion and poor durability.
Since the presser plate 5 directly presses the presser plate 5, the presser plate 5 is likely to be bent and deformed due to large bending stress acting between the adjacent processed materials 7, 7.

Therefore, the present invention has been devised as a mounting tool for workpieces that can grip and release multiple workpieces with simple operations, while also preventing premature damage to the threaded parts and bending and deformation of the holding plate. The purpose is to provide ingredients.

[Means and actions for solving problems]

A plurality of workpiece support parts are formed in a main body provided with a member to be clamped, a connecting rod having an operating lever is rotatably supported, a presser plate is movably supported along the connecting rod, and A pressing plate is attached to this holding plate facing the workpiece support part, a spring is interposed between the main body and the holding plate, and a protruding piece on which the operating lever rides is provided on the holding plate to operate it. By moving the lever onto or off the protrusion, the presser plate is moved toward the main body or away from the main body, and the workpiece is gripped by the presser plate and the workpiece supporter. It was made possible to release it.

〔Example〕

FIG. 4 is a front view of the material to be treated suspended vertically. A racking jig 11 is attached to the electrolytic frame 10, which is transported by a crane (not shown), and is clamped by the racking jig 11. Jig 1
A plurality of materials 13 to be processed are held by the handle 2 .

As shown in FIGS. 1, 2, and 3, the mounting jig 12 connects one side plate 14 and the other side plate 15 with a pair of connecting members 16, 16, and a pair of connecting members 16, 16. A main body 18 is provided with a member 17 to be clamped between 16 and 16, and a plurality of support parts 19 for the material to be processed, which are approximately semicircular recesses, are spaced from one side plate 14 and the other side plate 15 of the main body 18. In addition, presser plates 20 are arranged to face each other, and a presser plate 21 is attached to each presser plate 20 so as to face each of the workpiece support parts 19. The free end is bent into a substantially dogleg shape to have a resilient force and to be elastically deformed.

The connecting rod 23 is inserted through the through hole 22 of the holding plate 20, and the threaded portion 23a is screwed into the screw holes 14a and 15a of the one side plate 14 and the other side plate 15 of the main body 18, and the holding plate 20 is inserted along the connecting rod 23. At the other end of the connecting rod 23 there is an operating lever 2.
4 is fixed thereto, and around the through hole 22 of the presser plate 20 is a pair of approximately semicircular protrusions 25, 25.
is approximately circular, and adjacent protruding pieces 25, 25
In between, there is a gap 2 that is slightly wider than the operating lever 24.
6, and a pair of protruding pieces 2
The upper surfaces 25a and 25a of the ends of the main body 18 are sloped, and a spring 27 fitted around the connecting rod 23 is interposed between the one side plate 14 and the other side plate 15 of the main body 18 and the presser plate 20. The presser plate 20 is pushed outward, and the operating lever 24 is pressed against the presser plate 20.
This causes the presser plate 20 to move by the protruding length of the protrusion 25, and the presser plate 21 to move accordingly. When the lever 24 is rotated, the threaded portion 23a is inserted into the threaded hole 14.
Since it screws into a and 15a and returns,
The presser plate 20 will move by that amount.

Then, the electrolytic frame 10 holds the material 13 to be treated and
5a, rotate the operating lever 24 so that it fits into the gap 26 between the pair of protrusions 25,
0 comes into contact with the outer surface 20a of 0.

As a result, the pressing plate 20 is pushed by the spring 27 and moves outward by the return stroke due to the protrusion length of the protrusion 25 and the screw action caused by the rotation of the connecting rod 23, and the pressing plate 21 and the processed material storage section 19 are moved outward. The interval becomes wider, and the material to be treated 13 can be inserted smoothly between the press plate 21 and the material support part 19 from the longitudinal direction.

At this time, a stopper 28 may be attached to one side plate 14 and the other side plate 15, as shown by the imaginary line in FIG. 2, and the material to be treated 13 may be positioned by coming into contact with the stopper 28.

Then, as shown in FIG. 5b, the operating lever 24
When it is rotated 90 degrees and rides on the upper surface of the pair of protrusions 25, 25, the presser plate 20 resists the spring 27 and moves inward by the return stroke due to the protruding length of the protrusions 25 and the screw action due to the rotation of the connecting rod 23. As the process moves, the distance between the press plate 21 and the workpiece support part 19 becomes narrower, and the workpiece 13 is strongly pressed and gripped by the workpiece support part 19 by the press plate 21 .

At this time, the operating lever 24 rides smoothly along the sloped end upper surface 25a of the protrusion 25.

Note that since the pair of operating levers 24, 24 rotate in opposite directions, the threaded portion 23 of the pair of connecting rods 23
One side of a is a right-handed screw, and the other is a left-handed screw.

In the above embodiment, the threaded portion 23a of the connecting rod 23 is screwed into the screw holes 14a, 15a, but the connecting rod 23
may be rotatably supported on one side plate 14 and the other side plate 15 of the main body 18.

Alternatively, as shown in FIG. 6, the operating lever 24 may be attached to only one of the connecting rods 23, and a spring 27 may be fitted into the connecting rod 23.
In this way, it is only necessary to operate one operating lever 24, so the operation becomes easy. In this case, the fitting portion between the other connecting rod 23 and the through hole 22 of the presser plate 20 prevents the presser plate 20 from becoming stiff.

[Effect of idea]

When the operating lever 24 is placed in the position where it rides on the protrusion 25, the presser plate 20 moves toward the main body 18 by the protruding length of the protrusion 25 against the spring 27, and the presser plate 21 and the workpiece support part 19 are moved. When the distance becomes narrower and the operating lever 24 is moved to a position where it is removed from the protrusion 25, the presser plate 20 is moved away from the main body 18 by the spring 27 until it comes into contact with the operating lever 24, thereby supporting the presser plate 21 and the material to be processed. Since the distance between the control lever 24 and the protruding piece 25 is widened,
and the non-processed material 13 is inserted between the press plate 21 and the processed material support part 19 in this state,
Next, when the operating lever 24 is placed in a position where it rides on the protruding piece 25, the pressing plate 21 is strongly pressed against the material 13 to be treated and grips it.

Therefore, by operating the operating lever 24 to a position where it is removed from the protruding piece 25 and a position where it rides on the protruding piece 25, a plurality of workpieces 13 can be gripped,
A large number of materials to be treated 1 can be placed in the electrolytic frame 10.
3 can be installed and removed with simple operations while hanging vertically.

Furthermore, since the press plate 21 attached to the press plate 20 is pressed against the workpiece 13, no large bending stress is applied to the press plate 20.
0 is not bent and deformed, and the material to be treated 1
Since the gripping force No. 3 is supported by the elastic force of the pressing plate 21, no unreasonable force is applied to each part, which prevents early damage and improves durability.
