Embodiment 1

[0038] A partition surface treatment device for nut parts, such as figure 1 As shown, the parts that do not need to be conductive (the parts that do not touch each other) on the clamping head 1, the hanging rod 2 and the fixed plate 3 are insulated and coated with electroplating glue, and the device is assembled after the glue is cured, or after assembly Apply insulating coating. During assembly, the clamping head 1 is first installed on the fixed plate 3, then the hanging rod 2 is installed on the fixed plate 3 with the hanging rod fixing nut 4, and finally the hook 5 is threaded on the upper end of the hanging rod 2, wherein the hook 5 is suspended and connected on the pole rod 8; the upper part of the clamping head 1 is cylindrical, such as Figure 6 shown.

Embodiment 2

[0040] First, the clamping head 1 is installed on the fixed plate 3, the hanging rod 2 in the suspension device is installed on the fixed plate 3 with the hanging rod fixing nut, and the hook 5 is sleeved on the upper end of the hanging rod 2, and the clamping head 1, The non-contact parts of the hanging rod 2 and the fixed plate 3 are coated with a layer of electroplating glue for insulation, wherein the hook 5 is suspended and connected to the pole 8; the upper part of the clamping head 1 is tapered, such as Figure 7 shown.

[0041] A partitioned surface treatment method for nut-like parts is completed based on the above-mentioned device. First, a layer of insulating electroplating glue is applied to the parts of the clamping head 1 and the fixed plate 3 that are not in contact with the nut workpiece 6, and then the clamping head 1 and the suspension device are fixed on the fixed plate 3, the hook 5 in the suspension device is connected with the external pole 8, and then th...

Abstract

The invention discloses a nut part partitioned surface processing device and method, and belongs to the field of nut part surface processing. A local solution exchanging rate is reduced through standcolumn regions of a clamping head, a differential processing effect is formed for a thread region and a non-thread region, a reaction rate of the thread part in the surface processing process is reduced, and therefore screwing and fastening performance of a processed thread is ensured. For processing of a nut part, a processing rate of the thread part is low, a processing rate of a non-thread partof an outer surface is high, and the technical problem that thread screwing performance is reduced by equivalently processing the thread part and the outer surface part in the prior art is changed. The nut part partitioned surface processing device is simple in structure, low in production cost and suitable for machining and processing nuts on a large scale, the processing method is easy to operate and high in practicability, can process surfaces of a plurality of nuts and effectively shortens a surface processing cycle of a large batch of nuts.

Description

technical field [0001] The invention belongs to the field of surface treatment of nut parts, and relates to a partitioned surface treatment device and a treatment method for nut parts. Background technique [0002] The fit problem of nut parts after surface treatment has always been a difficult problem in the fastener processing industry. The commonly used surface treatment methods for nut parts include electroplating and electrochemical polishing, and the commonly used clamping methods are bundled hanging or drum loading. This kind of clamping method has great disadvantages, such as low binding and hanging efficiency, easy loosening of the workpiece, poor conductive contact, and easy ablation of the workpiece with high current, etc.; there is unavoidable contact between the workpieces loaded on the drum, which is required for plating treatment. Large current or insufficient electrochemical polishing treatment will lead to uneven coating or even missed plating, missed polis...
