Abstract

The invention relates to the field of micro motor manufacture, and particularly discloses a rotor shaft pressing machine for manufacturing a micro motor. The rotor shaft pressing machine comprises a base, and is characterized in that an upright post is fixed on the base; a power device is mounted at the upper end of the upright post; a pressing down device is in threaded connection with the lower end of the power device; a rotor shaft hole is formed in the lower surface of the pressing down device; a fixing seat is movably connected to the base; a slotted hole is formed in the fixing seat; a positioning sleeve is matched with the slotted hole; the inside diameter of the upper part of the positioning sleeve is large while the inside diameter of the lower part of the positioning sleeve is small; the inside diameter of the upper part of the positioning sleeve is the same as the diameter of a rotor iron core; the inside diameter of the lower part of the positioning sleeve is the same as the diameter of the rotor shaft. As manual operation in the prior art is replaced by mechanical operation, and the mounting of the rotor shaft is realized through the pressing down device, the mounting of the rotor shaft becomes easy, time-saving and labor-saving, and the production efficiency is greatly improved.

Described power set are cylinder.

Described power set comprise a tooth bar, and rack tube is on the transverse slat on column top and can move up and down on transverse slat, and tooth bar turns gear and engages with one, turn gear and rotate by axle turnable the wind control being fixed on column.

Described power set comprise tooth bar and oscillating cylinder, and rack tube is on the transverse slat on column top and can move up and down on transverse slat, and the output of oscillating cylinder is connected with and turns gear, described in turn wheel and rack engagement.

The invention has the beneficial effects as follows:

Mechanically actuated operation is changed in original manual operation by the present invention, realizes the installation of armature spindle by hold-down devices, and the installation of armature spindle is become easily, time saving and energy saving, has greatly improved production efficiency.

In figure, 1 base, 2 columns, 3 hold-down devices, 4 rotor shaft hatchs, 5 cylinders, 6 armature spindles, 7 holders, 8 abutment sleeves, 9 slotted eyes, 10 rotor cores, 13 tooth bars, 14 turn gear, 15 transverse slats, 16 winds, 17 oscillating cylinders.

(5) embodiment

Accompanying drawing is specific embodiments of the invention.As shown in Figures 1 to 5, this kind made micromachine pressure rotor machine, comprise base 1, in base 1 one sides, be fixed with column 2, column 2 upper ends are provided with power set, the power set lower end hold-down devices 3 that is threaded, the lower surface of hold-down devices 3 upwards has rotor shaft hatch 4, on base, be connected with holder 7, on holder 7, have slotted eye 9, slotted eye 9 is supporting abutment sleeve 8, and the internal diameter of abutment sleeve 8 is up big and down small, the equal diameters of the internal diameter of top and rotor core 10, the equal diameters of following internal diameter and armature spindle 6; Calculate with mounted armature spindle 6 and rotor core 10, the degree of depth of rotor shaft hatch 4 should with armature spindle 6 equal in length that is exposed at rotor core 10 one end, the length that the other end is exposed at the armature spindle 6 outside rotor core 10 equals the degree of depth of the inner-diameter portion whose of washing in abutment sleeve 8.

Above-mentioned power set can make following three kinds of embodiments: as shown in Figure 1, the first is cylinder 5, it is fixed on the transverse slat 15 on column 2 tops, and for ease of the switching of operative employee's control cylinder 5, the switch of control cylinder 5 can be put into operative employee's side or be put into underfooting.

The second execution mode of power set is: as shown in Fig. 6, Fig. 8, it comprises a tooth bar 13, the upper end of tooth bar 13 is smooth cylindrical, it is enclosed within on the transverse slat 15 on column 2 tops and can on transverse slat 15, moves up and down, transverse slat 15 plays fixing, position-limiting action, the end portion of tooth bar 13 turns gear 14 and engages with one, the rotating shaft that turns gear 14 is fixed on column 2 by bearing and a wind 16 of its end connection, control by wind 16 rotation that turns gear 14, thereby control rising and falling of hold-down devices.
