The invention discloses a tooling clamp for processing an insulating collar turning. The tooling clamp comprises a concave clamp (8) and a convex clamp (9), wherein the concave clamp (8) comprises a jaw chuck A (10) and a plurality of equant sectorial blocks A (11), the sectorial concave part in each equant sectorial blocks A (11) is composed of a sectorial plane A (13) and a arc-shaped surface side wall A (14), the convex clamp (9) comprises a jaw chuck B (15) and a plurality of equant sectorial blocks B (16), a sectorial plane C (19) is also arranged on the outer side of each equant sectorial block B (16), and the invention further discloses a processing method. The tooling clamp provided by the invention has the advantages that the gripping force is even, so that the deformation of a workpiece is avoided, the clamping efficiency is improved, the time is saved, the workpiece quality and the processing efficiency are improved, and the consistency and the reliability of a part is increased as well.

The invention provides an aluminum alloy conductor pole manufacturing method. According to the method, a conducting body is manufactured firstly, specifically, extrusion forming, broaching forming and mechanical turning of a conducting rod are carried out; then a conducting head is manufactured, specifically, machining of the conducting head is mainly carried out; and finally, the conducting head and the conducting rod are connected through a no-keyhole stirring friction welding technology. By means of the aluminum alloy conductor pole manufacturing method, the problem of the welding quality of large-thickness small-diameter circular seams is solved, and the method has remarkable advantages compared with the prior art. By adoption of the conductor pole manufacturing method, the joint assembly design of the conducting rod and the conducting head as well as the no-keyhole stirring friction welding technology, the qualified rate of manufacturing of conductor poles is greatly improved, the production efficiency is improved, and the production cost is reduced. Tests prove that by adoption of the aluminum alloy conductor pole manufacturing method, the manufacturing dimension precision of the conductor poles meets the design requirement, weld joints are continuous and compact in texture, the defects including pores, impurities and keyholes are avoided, and automatic control is achieved in the production process; and the yield of one-time welding is increased from 40% to 95%.

The invention discloses an arc extinguish chamber assembling tool. The arc extinguish chamber assembling tool comprises a bottom plate and an arc extinguish piece positioning plate; a guide hole is formed in the middle of the arc extinguish piece positioning plate; clamping grooves are formed in the front end of the arc extinguish piece positioning plate, and a limiting step is arranged below the front end of the arc extinguish piece positioning plate; an arc extinguish chamber assembling area is arranged in the center of the bottom plate and is provided with a positioning mechanism; a limiting baffle and a guide pin are fixedly arranged behind the arc extinguish chamber assembling area; the arc extinguish piece positioning plate is located above the bottom plate and is in sliding connection with the bottom plate, the limiting baffle is located in front of the limiting step, the guide pin is arranged in a guide hole, and when the arc extinguish piece positioning plate is pushed forwards, the front end of the arc extinguish piece positioning plate can stretch into an arc extinguish chamber from the open end of the assembled arc extinguish chamber, and when the rear surface of the limiting baffle is in abut joint with the front surface of the limiting step, arc extinguish pieces are correspondingly clamped in the clamping grooves. The assembling tool is convenient to operate, safe, reliable, and capable of reducing the labor intensity and improving the assembling efficiency and the one-time yield.
