Description

[Detailed Description of the Invention] This invention relates to a holding device for surface treatment materials when surface treating materials such as alumite.

A conventional example of a surface treatment material is explained with reference to FIG. 3. The movable holding part 2 and other parts are pivoted between the side walls 4 and 4 of the holding case 1 by a support shaft 7 equipped with a stopper 16 to prevent removal. It is a support.

By the way, during surface treatment, the surface treatment liquid adheres to the holding device for the surface treatment material and corrodes each component, making it unusable.

In particular, the processing liquid accumulates around the support shaft 7, which tends to corrode the support shaft 7.

However, as shown in the figure, the conventional holding device for surface treatment materials uses at least two parts, the support shaft 7 and the stopper 16, which not only increases the number of parts and increases costs, but also requires replacement of parts. Alternatively, replacing the support shaft 7 is very troublesome.

This invention was devised to solve the above-mentioned conventional problems, and its purpose is to provide an economical holding device for surface treatment materials that allows easy replacement of parts including the spindle. .

This invention will be explained below with reference to illustrated embodiments.

A movable holding part 2 and a swing lever 3 are attached to a holding case 1.

The holding case 1 has a substantially groove-shaped cross section that is deep at the tip and gradually becomes shallower toward the rear.

A notch 5 is provided at the tip of the side walls 4, 4 of the holding case 1.
, 5 are formed correspondingly.

The movable holding part 2 has sawtooth-shaped holding claws 6 that are continuous in an arc shape, and is formed into an arcuate substantially fan shape, and is located at the upper position where the notches 5, 5 between the side walls 4, 4 are formed. It is rotatably supported by a support shaft 7.

Then, the surface treatment material 10 is held between the movable holding part 2 and the fixed holding part 9 which is integrally formed at the tip of the current-carrying bar 8 and is disposed at the bottom of the holding case 1 so as to face the movable holding part 2. It is designed to be held in place.

The swinging operation of the movable holding part 2 is made possible by a swinging lever 3.

The swing lever 3 is pivoted between the side walls 4, 4 of the holding case 1 with a support shaft 7 having a lever function.

The movable holding part 2 and the swinging lever 3 have both ends attached to the movable holding part 2.
and the swinging lever 3 via links 11 which are each pivotally supported by a support shaft 7.

All of the support shafts 7 are steel split pins.

The support shaft 7 can be easily pulled out by cutting the head portion 7a of the support shaft 7 with a cutter or the like, and can be easily fixed by bending the leg portion 7b.

A sheath 12 is attached to the support shaft 7, so that the movable holding part 2, the swing lever 3, and the link 11 can move smoothly.

In addition, the support shaft 7 is a steel taper pin instead of a steel cotter pin,
Steel split taper pin, steel parallel pin, and spring pin (all Japanese industrial standard products).

) allows repeated use.

Reference numeral 13 is a spring.

The spring 13 urges the swing lever 3 in the direction of arrow 14, and at the same time urges the movable holding portion 2 in the direction of arrow 15 via link 11.

Therefore, the surface treatment material 10 is reliably held between the movable holding part 2 and the fixed holding part 9.

This invention consists of the above structure, including a support shaft 7 that pivotally supports the movable holding part 2 and the swinging lever 3 on the holding case 1, and a shaft 9721 for linking the movable holding part 2 and the swinging lever 3.
1. The support shaft 7 that supports both ends is made of a steel cotter pin, and the steel cotter pin can be easily pulled out by cutting off its head with a cutter, and the legs can be removed. Since it can be easily fixed by bending it, even if each part of the holding device becomes corroded and becomes unusable, it can be easily replaced.

Further, since steel split pins are inexpensive, they are extremely economical.
