the utility model relates to a drying and pressing tool for molding an insulating sleeve of a collector ring of a motor.

Background art:

along with the development and progress of the society, the production and manufacturing technology of the motor is increasingly refined, in order to improve the performance of the motor, the requirements on the carrying process and the manufacturing precision of each part of the motor are higher and higher, the fineness degree of each part of the motor can directly reflect the integral operation performance of the motor, the motor parts are continuously developed along with the progress and the technology update of the society, the insulation structure and the process carrying form of the collecting ring sleeve are obviously improved, the prior technical method cannot meet the daily manufacturing of the motor and the use requirement of the motor on the insulation performance, and the new insulation mode is born, the derived technical scheme is not suitable, so a new tool is needed to meet and guarantee the production requirement of the new technical scheme.

The utility model content is as follows:

the utility model aims to provide a drying and pressing tool for molding an insulating sleeve of a collector ring of a motor, which can meet the production requirement of a novel insulating sleeve and ensure the overall performance and the qualification rate of the insulating sleeve, thereby improving the overall performance of the motor during manufacturing and operation. The utility model adopts the following technical scheme: a motor collecting ring insulating sleeve forming drying and pressing tool is formed by matching and assembling a connecting base plate (1), an inner pressing ring (2), an outer pressing ring (3), a fastening bolt (4) and a locknut (5), wherein a boss (7) matched with the inner diameter of a metal sleeve (6) is arranged on the end surface of one side of the base plate (1), and a hoisting hole (9) is formed in the center of the base plate (1); the lateral wall of the outer pressing ring (3) is provided with a threaded hole (11), the threaded hole (11) is matched with a fastening bolt (4), a metal sleeve (6) is sleeved on a boss (7) on the end face of the chassis (1), an insulating sleeve (8) is fixed on the outer side of the metal sleeve (6), the inner pressing ring (2) is fixed on the excircle of the insulating sleeve (8), the outer pressing ring (3) is assembled on the conical surface on the outer side of the inner pressing ring (2), the fastening bolt (4) penetrates through the threaded hole (11) in the outer pressing ring (3) to be tightly pressed on the outer wall of the inner pressing ring (2), and a check nut (5) is fastened on the outer wall of the outer pressing ring (3).

The inner pressing ring (2) is divided into four parts, the outer side of the inner pressing ring (2) is conical, a through chute (10) is arranged in the wall thickness direction of the inner pressing ring (2), and the inner side of the outer pressing ring (3) is conical.

The working principle of the utility model is as follows:

at first put the chassis level back, embolia the cooperation boss on the chassis terminal surface with product metal sleeve, after metal sleeve's outside winding insulating sleeve, laminate the interior clamping ring on insulating sleeve's excircle, assemble outer clamping ring again on the clamping ring outside conical surface including, through applying certain pressure to outer clamping ring, outer clamping ring downstream, because interior clamping ring is the conical surface contact with outer clamping ring, interior clamping ring can follow the internal diameter shrink along with outer clamping ring downstream, thereby compaction insulating sleeve, fastening bolt passes the screw hole on the outer clamping ring, the fastening bolt of screwing makes its top tighten on the outer wall of interior clamping ring, simultaneously with lock nut screw laminate on the outer wall of outer clamping ring, prevent behind the pressure release because stress interior clamping ring rises outward. The tool can effectively ensure the one-step forming of the insulating sleeve, ensure the tightness of the insulating sleeve and ensure the excellent use performance of the insulating sleeve.

The specific use of the tool can be referred to the following examples: put the chassis and level the back, embolia the cooperation boss on the chassis terminal surface with product metal sleeve, after metal sleeve's outside winding insulating sleeve, laminate the interior clamping ring on insulating sleeve's excircle, on clamping ring outside conical surface including the assembly of outer clamping ring again, through applying certain pressure to outer clamping ring, outer clamping ring downstream, because interior clamping ring is the conical surface contact with outer clamping ring, interior clamping ring can follow the internal diameter shrink along with outer clamping ring downstream, thereby compaction insulating sleeve, fastening bolt passes the screw hole on the outer clamping ring, the fastening bolt of screwing makes its top tighten on the outer wall of interior clamping ring, screw the laminating on the outer wall of outer clamping ring with lock nut simultaneously, prevent behind the pressure release because the clamping ring rises outward in the stress. The tool can effectively ensure the one-step forming of the insulating sleeve, ensure the tightness of the insulating sleeve and ensure the excellent use performance of the insulating sleeve.

The utility model has the beneficial effects that:

the mode of the interior outer conical surface complex of adoption, thereby the size of the inner diameter of pressing ring in the displacement contact through the conical surface changes, diameter change through interior clamping ring exerts sufficient pressure to winding insulating layer, tightly wrap up on insulating sleeve's the outside, with the clearance compaction between each layer of insulating sleeve, avoid the remaining of bubble, thereby be a unified whole with each layer compaction, and after the compaction, make insulating sleeve sclerosis through baking and pressing, can prevent its heating deformation effectively, and can prevent the insulating sleeve internal diameter and break away from metal sleeve's external diameter.

The insulating tape mode in the past is directly twined the insulating layer on metal sleeve, rely on toughness and the rigidity of insulating layer self material to make and closely laminate between each layer, when the outside pulling force of exerting withdraws, because the elastic deformation of the remaining stress of material self and material can lead to separating between the insulating layer, remain too much bubble after the thermal cure easily, carry out follow-up turning and take and can lead to fracture and separation between each level sometimes, the event needs new tool equipment to satisfy insulating sleeve's production condition, guarantee insulating sleeve's smooth shaping.
