Detailed Description

The utility model will now be described in detail with reference to figures 1-5 and the detailed description.

The utility model provides a tiny part surface treatment clamping frock, includes link plate 1, tension spring 2 and bolt pair 3, link plate 1 upper end has couple 1-1, the lower extreme that is fit with conducting rod 6 has mounting hole 1-2, tension spring 2 upper end extends has link 2-1, bolt pair 3 passes link 2-1, mounting hole 1-2 and fixes tension spring 2 in the below of link plate 1, through tension spring 2 adjacent two-round clearance centre gripping tiny part 4.

In one embodiment, the hanging plate 1 is preferably a copper hanging plate to improve conductivity.

In one embodiment, the tension spring 2 is preferably a titanium alloy tension spring, so as to improve corrosion resistance and prolong the service life of the tool. For example, a tension spring made of titanium alloy wires with the diameter of 1.5 mm can be used for clamping screws of M2, M2.5, M3 and M4 or cylinders with the diameter of 1-6 mm.

In one embodiment, in order to ensure good electrical conduction after the tension spring 2 is connected with the hanging plate 1, a gasket 5 is sleeved on the bolt pair 3, and the gasket 5 is located between the bolt head and the hanging ring 2-1.

In one embodiment, in order to form good electrical conductivity with the conductive rod 6 after the hook 1-1 is suspended on the conductive rod 6, the hook 1-1 is in an inverted U shape, ribs 1-3 are arranged on two inner side walls of the inverted U shape along the axial direction of the conductive rod 6, and the ribs 1-3 are located below the semicircular arc structure of the inverted U shape. The convex ribs 1-3 form line contact with the peripheral outer surface of the conductive rod 6, and the conductive rod 6 is limited in the hook 1-1 so as to be well contacted with the inner wall of the hook, thereby improving the connection reliability and conductivity of the hook 1-1 and the conductive rod 6.

The using method comprises the following steps: firstly, the tension spring 2 is stretched, a gap larger than the outer diameter of a part is formed between two adjacent circles of the tension spring 2, then the part is symmetrically inserted in the gap, and the upper and lower layers are arranged in a staggered mode, so that the tension spring 2 is ensured to be stressed uniformly, after the part is inserted, the stretching force is removed, the tension spring 2 is reset to clamp the part, and then the hook 1-1 is hung on the conducting rod 6 to carry out surface treatment on the part.

In order to improve the surface treatment efficiency of the tiny parts, one hanging plate 1 can be provided with two tension springs 2, and the surface treatment efficiency of the tiny parts is improved by alternately clamping the parts through the two tension springs.

The utility model is particularly suitable for clamping screw or cylinder parts, and can also be used for clamping micro parts with other shapes.

The above embodiments are only preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model, so that all equivalent modifications made by the appended claims shall be included in the scope of the present utility model.
