Embodiment

[0034] Choose two round steels with a diameter of 12mm and a length of 110mm to make the steel column 9, choose a 180mm×80mm×12mm steel plate to make the outer pressure plate 8, choose a M16×180mm screw rod 7 to form a bracket unit, and drill a 17mm hole in the middle of the outer pressure plate 8 The hole is the center hole, and a round hole with a diameter of 10mm and a length of 30mm is milled on both sides of the hole, which is the installation hole.

[0035] A bakelite sleeve 3 with four grooves with an inner taper of 1:10, a steel sleeve 2 with an outer taper of 1:10, and a gland form a taper sleeve combination unit, and the set steel sleeve 2 and bakelite sleeve 3 increase friction between them.

[0036]During the specific operation, screw the adapter nut II11 on the outer screw rod 7 of the outer pressure plate 8 to drive the screw rod 7, and the movement of the screw rod 7 drives the taper sleeve expansion unit to move to the outlet end of the valve motor base, and th...

Abstract

The invention discloses a device used for dismounting a valve motor core. The device comprises a casing, a coil core and a stator winding and further comprises a taper sleeve combination unit and a support unit, wherein the taper sleeve combination unit comprises a steel sleeve, a Bakelite sleeve and a pressure cover, the support unit comprises a screw, an outer pressure board, a steel column, a nut I and a nut II, the stator winding is arranged on the coil core, the steel sleeve and the Bakelite sleeve are coaxially sleeved outside the screw, the Bakelite sleeve is coaxially sleeved at an outer wall of the steel sleeve, the Bakelite sleeve is coaxially arranged at an inner wall of the coil core, and the pressure cover is coaxially arranged tail ends of the steel sleeve and the Bakelite sleeve. The device has a simple structure, is convenient to mount and use, guarantees damage-less mounting and dismounting of the motor core in the valve motor, greatly improves a qualified rate of the valve motor during maintenance, saves manpower and material resources, reduces enterprise cost and improves enterprise economic benefits.

Description

[0001] technical field [0002] The invention relates to an installation and disassembly tool, in particular to a device for disassembling and assembling the iron core of a valve motor. Background technique [0003] Due to the special requirements of the working conditions and environment of the valve motor, according to the requirements of GB4942.1-85, the minimum protection level of the valve motor is IP44, and the highest protection level is IP68. In order to meet the protection requirements, one end of the valve motor is usually a fixed bearing chamber (no through hole, the bearing chamber and the motor casing are cast as one), and the other end is an end cover type bearing chamber, such as figure 1 and figure 2 shown. [0004] In the prior art, there are mainly the following methods for valve motor maintenance: [0005] Method 1: After removing the coil end of the shaft end of the valve motor with a flat chisel, heat the casing with a gas flame, then turn the casing...
