Specific implementation mode

The utility model is described in further detail for middle embodiment below in conjunction with the accompanying drawings.

A kind of motor pin pressing tool as shown in Figure 1 to Figure 3, include dispose motor lower die 1 and can relatively under The upper mold 2 that mould 1 moves back and forth;Upper mold 2 includes matrix 21, the positioning thimble 22 positioned at 21 end of matrix, and pedestal is equipped with annular Magnet 23, the extending direction of positioning thimble 22 pass through the center of annular magnet 23.Annular magnet 23 is to being sleeved on positioning thimble Elastic positioning pin on 22 is pre-positioned, and elastic positioning pin deflection is prevented, and ensure that its assembly precision, improves assembly effect Rate.

As shown in figures 1 and 3, in the first embodiment, matrix 21 is cylindrical-shaped structure, and annular magnet 23 is close to positioning Thimble 22 is simultaneously looped around 21 outside of matrix.Magnet cartridge is convenient with replacing, and the elastic positioning pin of different quality need to only be replaced not Magnet with intensity can be met the requirements.In the outside of matrix 21,23 both ends of annular magnet are equipped with pair for the fitting of annular magnet 23 setting Its baffle ring 24 limited loosens to avoid magnet in frequent operation and with being generated in machine shaft contact process.

In second of embodiment, annular magnet 23 is located inside matrix 21, and positioning thimble 22 is partially embedded inside matrix 21, In assembling process, elastic positioning pin is sleeved on 22 outside of positioning thimble, and positioning thimble 22 and elastic positioning pin both pass through annular magnetic Iron 23 is arranged, to ensure locating effect of the magnet to elastic positioning pin.

As shown in figure 3, positioning thimble 22 is overlapped with the axis of matrix 21, positioning thimble 22 is partially submerged into matrix 21, is kept away Exempt to lead to elastic spacing pin deformation failure to the generation of positioning thimble 22 torque during 21 downlink of matrix.

Lower die 1 includes substrate 13 and the lower limit body 11 on substrate 13 and side limit body 12, lower limit body 11 and lateral spacing Position body 12 can be bolted on substrate 13.Lower limit body 11 includes arc-shaped limit face 111,111 direction of arc-shaped limit face Upper mold 2 is arranged, and arc-shaped limit face 111 is a part for column body side surface.Side limit body 12 is located at prolonging for arc-shaped limit face 111 It stretches on direction, side limit body 12 includes the first limiting plate 121, and the first limiting plate 121 is equipped with the limit coordinated with hex nut Slot 1211.For the motor of rolling shutter door by hex bolts power transmission, in assembling process, by motor housing as arc-shaped limit face On 111, hex nut is placed in limiting slot 1211, and dowel hole punching machine can be used to drive upper mold 2 towards 22 side of positioning thimble It is moved to 1 side of lower die.

First limiting plate, 121 side is equipped with the second limiting plate 122, and trimming bolt 1221 is provided on the second limiting plate 122, Trimming bolt 1221 passes through the second limiting plate 122 and is oppositely arranged with limiting slot 1211.Second limiting plate 122 and the first limiting plate 121 opposite sides offset, and the height of the two is different, forms hierarchic structure, the second limiting plate 122 is high compared with the first limiting plate 121, micro- Bolt 1221 is adjusted to be located at 122 upper end of the second limiting plate.The horizontal position of 1221 regulation motor of trimming bolt simultaneously limits it in axis Displacement to direction.

Positioning thimble 22 is arranged towards limiting slot 1211, can also be used mechanical arm will be flexibly positioned manually during use In positioning thimble 22, therefore elastic positioning pin is absorbed and fixed in upper mold 2 guide.Regulate the exudation of trimming bolt 1221 After length, by motor be placed on lower limit body 11 rotate hex nut so that dowel hole upward, hex nut one end with it is micro- Bolt 1221 is adjusted to offset, you can driving upper mold 2 moves down realization assembly.

Described above is only the explanation to the utility model so that those of ordinary skill in the art's can completely implements this Scheme, but be not limitations of the present invention, those skilled in the art can be as needed after reading this specification The modification of not creative contribution is made to the present embodiment, these are all without creative modification, but as long as in this practicality It is all protected by Patent Law in novel right.
