An electroplating jig for holding slotted needles

Abstract

The invention relates to an electroplating clamp for clamping groove pins. The electroplating clamp comprises a hoisting structure, a main body clamping structure and a flow choke structure, wherein the main body clamping structure comprises a plate groove, a cover plate and a conductive plate, the plate groove is connected with the cover plate, the conductive plate is clamped between the plate groove and the cover plate and is fixed on the plate groove through a screw a and a nut a, a clamping groove capable of clamping the groove pins is arranged in the plate groove, a cotton adhesive tape is arranged at the connection of the cover plate and the conductive plate and is used for buffering the clamping effect on the groove pins, the flow choke structure includes a flow choke frame and a U-shaped copper rod, the flow choke frame is composed of a front flow choke plate and a rear flow choke plate, the flow choke frame is connected with the plate groove through a screw b and a nut b, thepin grooves of the groove pins are located in the flow choke frame, and the pin hooks of the groove pins are located between the front flow choke plate and the rear flow choke plate. The electroplating clamp has the advantages of reasonable structure, reliability in clamping, and ensuring of the clamping consistence of the groove pins.

Description

technical field [0001] The invention belongs to the technical field of electroplating treatment for grooved needles of warp knitting machines, in particular to an electroplating fixture for clamping grooved needles. Background technique [0002] Knitting equipment is the key equipment for the knitting machine to directly contact with the fiber and shape the fabric during the weaving process, and it plays a vital role in the quality of the fabric. During the knitting process, poor surface roughness and poor wear resistance of knitting equipment are likely to cause the knitting equipment to pull and break the fabric. Therefore, the influence of surface defects on fabric quality during knitting needle operation can be compensated by appropriate surface treatment of knitting equipment, and the service life of knitting equipment and fabric quality can be improved. [0003] The warp knitting machine groove needle is used in conjunction with the needle core. The needle core recipr...
