Description

Method for detecting outlet clamp product of red copper or copper-aluminum transition power equipment Technical Field The invention relates to the technical field of product detection, in particular to a method for detecting an outlet clamp product of an integrally-stamped red copper or copper aluminum transition power device. Background The existing power equipment wire outlet clamp is of a two-half split structure, the main stream is made of red copper or copper aluminum transition materials, but the split structural design of the existing power equipment wire outlet clamp is complex in processing procedures, two clamping plates and conductor binding posts need to be pressed synchronously during installation, bolts are threaded for locking, operation convenience is poor, and high-efficiency operation requirements of electric power construction are difficult to adapt. Based on the above, we have developed an integrated punching and bending power equipment wire outlet clamp, the whole wire outlet clamp is in a U-shaped clamping form, one ends of two opposite half clamping plates are connected through an integrated connecting part, when in use, a conductor binding post (rod) is only required to be placed into the arc-shaped clamping parts in the middle of the two clamping plates, then a bolt is penetrated through connecting holes on two sides of the corresponding arc-shaped clamping parts of the two clamping plates and screwed up, the clamping operation can be completed, when in manufacture, a continuous precise punching scheme is adopted, a punching and precise cutting compound module is used for cutting and punching a rectangular blank, and simultaneously punching preset forming positions of the two arc-shaped clamping parts to form a punching center positioning line, then the arc-shaped clamping parts are obtained through a punching die under the conditions of the die temperature of more than 100 ℃, and then bending is carried out step by step, and bending is carried out in a bending die set to form an angle of 85 DEG to 89 DEG and an angle of 89.5 DEG to 90.5 DEG with the initial horizontal plane. Although the integral wire outlet clamp can ensure higher molding precision through a precision stamping bending molding process, the copper part of the adopted red copper or copper aluminum transition material has inherent elastic characteristics (such as T2 red copper with purity more than or equal to 99.90 percent), and is influenced by unavoidable practical production factors such as blank thickness difference, slight fluctuation of bending and pressure maintaining process parameters of different dies and the like in a batch production process, after the wire outlet clamp is bent and molded, elastic rebound of different degrees is still possible, the rebound can cause parallelism deviation of two clamping plates, further the problems of insufficient centering of the arc-shaped clamping parts in the middle parts of the two clamping plates, coaxiality deviation of corresponding locking mounting holes at two sides and the like are caused, the coaxiality of the locking mounting holes directly influences the smooth penetration and uniform distribution effect of clamping force of bolts, and the centering degree of the arc-shaped clamping parts determines the attaching and clamping effect of the conductor binding post, and the attaching and clamping effects are important indexes related to the conductivity, the clamping stability and the safety in use, and the important indexes for measuring the consistency and manufacturing quality of products. However, in the prior art, aiming at the detection of the irregular small parts, the manual detection is firstly relied on, the manual detection efficiency is low, the detection deviation is easily introduced due to the manual operation error, the conventional manual detection method can only make qualified or unqualified terminal qualitative judgment, the accurate quantitative detection cannot be carried out on common process fluctuation deviations such as hole site deviation, out-of-tolerance rebound quantity and the like found in the detection, the corresponding correctable parameters cannot be given out, the consistency is poor, and a large number of the rescued deviation products are misjudged and scrapped, so that the production cost is greatly increased. Secondly, some automatic detection equipment exists in the industry, but because the integrated wire outlet clamp has the characteristics of small specification and light weight, and the convex clamping parts at the middle parts of the two clamping plates break the positioning suitability of the traditional conveying equipment, the traditional conveying equipment is easy to roll, topple or deflect on the traditional conveying line, and cannot be conveyed to a detection station in a stable and uniform posture, so that the integrated wire outlet clamp becomes a core technical bottleneck of automatic detection.
