Description

Technical Field

[0001] The utility model relates to the technical field of surface treatment process, in particular to a shielding fixture for heating flow-distributing plate parts. Background Art

[0002] The heating flow plate parts are a typical combination of IC equipment parts and electrical devices, and are characterized by a machined rotating body + heating wire. The hollow part of the general heating flow plate is inlaid with heating wires, temperature measuring rods and other electrical components. Moreover, due to the special shape, they are often poorly sealed, and the heating wire position accuracy has high requirements. In the end, no corrosive liquids or stolen goods can remain in the heating cavity. The surface treatment process is cumbersome, and liquids are prone to leakage. The requirement for tooling is that one-time packaging meets the shielding requirements of subsequent surface treatment.

[0003] With the development of electrical assembly products, more and more special surface treatments are required for flow plate products. Traditional surface treatment processes require adhesive tapes, and the tape sealing is very easy to loosen during the processing, resulting in substandard cleanliness and non-compliance with requirements, and even scratching electrical components. Repeated sealing wastes time and materials. Utility Model Content

[0010] The flatness of the contact surfaces between the blind plate A and the blind plate B, and between the blind plate A and the flow equalizer and other parts is not greater than 0.05 mm.

[0011] After the nut and the hexagon socket screw A are tightened, the hexagon socket screw A is perpendicular to the inclined surfaces of the blind plate A and the blind plate B.

[0012] The material of the hexagon socket screw A and the hexagon socket screw B is stainless steel.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

A blind plate sealing structure is adopted, and the structural characteristics and space utilization of the heating wire product are fully considered. Two sets of sealing blind plates are designed, and collisions and interferences are avoided during the transportation and interaction process to save space. It can protect similar types of components, electrical appliances and pipelines to prevent product contamination and damage. After the fixture is clamped once, the product body can be flipped over so that the flow plate or other similar products can meet various processes such as cleaning and polishing. The processing can ensure that multiple surface treatment processes are completed in one installation, without repeated installation, and meet the protection requirements of each section of the workpiece process.

[0015] The utility model fixture is a universal tooling, which can meet the clamping requirements of various flow plate parts of different sizes and specifications, and can also be installed with a quick-change plate, and the quick-change plate is designed to match the parts of different flow plate specifications. The fixture is easy to use, the fixture body is light and can be flipped and clamped at will, the assembly efficiency is higher, the cleanliness qualification rate of the product after use is high, and it can effectively ensure that the product can be transported smoothly without damage after assembly, and is suitable for mass production.

[0016] The fixture of the utility model can be applied to the clamping method of parts under light cutting stress, and adopts a three-point plane positioning method for positioning, thereby ensuring that the parts are as flat as possible and reducing the influence of tolerance accumulation on the positioning accuracy of the parts.
