End cap 1 is located at the top of apparatus of the present invention, for protecting the device inner member, when apparatus of the present invention are inverted,
Prevent bearing 11 and mandrel 12 from deviating from from the inner chamber 3e in power bar 3.
Pedestal 4 is the tubular structure that cross section is inverse u shape, and upper bottom surface is provided with through hole, and through-hole wall is provided with
Screw thread.
Pedestal 4 provides the support with test specimen for apparatus of the present invention, and protects magnet 5, super heated rubber pad 7, electric heating piece 8.Base
Seat 4 is threadedly coupled with power bar 3 by power bar screw thread 3b.After pedestal 4 is fixed, magnet 5 can be changed with test specimen with rotating end cap 1
Attraction.
Power bar 3 is the cylindrical structure that cross section is T-shape, and the prominent cylindrical outer side positioned at lower part sets strong bar screw thread
3b, the screw thread with the through-hole wall of pedestal 4 is engaged；Inside power bar 3, three internal diameters are disposed with from top to bottom and are progressively subtracted
The endoporus of small and overall insertion power bar 3：Inner chamber 3e, mount 3d, endoporus 3c；
Mandrel 12 is located at the center of apparatus of the present invention, is directly connected in magnet 5, and power is transferred into bearing 11, axle
Hold 11 and power is transferred to power bar 3.
The mandrel top cover 12a of mandrel 12；Mandrel guide post 12b；Mandrel thread 12c arranges from top to bottom, and external diameter according to
It is secondary to diminish.The end of mandrel 12 is mandrel top cover 12a, and mandrel top cover 12a bottom surface peripheries directly bear against the upper of bearing 11
End face, the upper bottom surface of mandrel top cover 12a is set to stepped form, for dismounting mandrel 12 provides the point of application and position.Mandrel 12
Stage casing be mandrel guide post 12b, down protruded from mandrel top cover 12a bottom surfaces center section, be that bearing 11 provides inside and leads
To axle；Bottom, mandrel 12 is directly threadedly coupled by the mandrel thread 12c of bottom section with magnet 5.
The lower surface of bearing 11 directly bears against the upper surface of mount 3d, and mount 3d in the horizontal direction for axle
Hold 11 carry out it is spacing.Bearing 11 is end face bearing, i.e., when power bar 3 rotates, upper and lower is carried out for mandrel 12 by bearing 11
Upward lifting, and mandrel 12 will not be rotated with.
So so that power bar 3 is located at the inside of apparatus of the present invention, it is possible to provide the active force of lifting magnet 5, magnetic is changed with this
Iron 5 is adsorbed in the power of test specimen.The inside of power bar 3 is provided with endoporus 3c, is that magnet 5 provides assembly space.Mount 3d in power bar 3
The spacing of bearing 11 is provided.It is bearing 11 and mandrel 12 in the inner chamber 3e that the top of power bar 3 is set.
End cap 1 is fixedly connected with power bar 3 by bolt 2, and bolt 2 is arranged symmetrically for ring, position and the power bar 3 of bolt 2
Power bar screwed hole 3a be correspondingly arranged.When needing rotary force rod 3 to exert a force, directly can implement rotating end cap 1.
Bearing 11 in the inner chamber 3e of power bar 3, between mandrel 12 and power bar 3, the mandrel top cover of one end and mandrel 12
The mount 3d directly contacts of 12a bottom surfaces directly contact, the other end and power bar 3.Bearing 11 delivers mandrel 12 to power bar 3
Power, because the coefficient of friction of bearing 11 is relatively low, so the moment of torsion for rotating power bar 3 is smaller.Meanwhile, magnet 5 will not be sent out with power bar 3
Raw servo rotary, and then protect jelly.
Magnet 5 provides attraction for apparatus of the present invention, and one end of magnet 5 is internal whorl, the mandrel spiral shell of direct mandrel 12
Line 12c is joined directly together.The other end of magnet 5 is joined directly together with super heated rubber pad 7.
Super heated rubber pad 7 is installed on the bottom of magnet 5, and the two contact surface is bonded using high-temp glue.
Electric heating piece 8 can be heating film, electric heating piece, electric heating coil etc., and electric heating piece 8 is fixedly connected with super heated rubber pad 7, connection
Mode is bonded for high-temp glue.The electrode 9 of electric heating piece 8 is connected by the fairlead 10 on pedestal 4 with external power source.It is outer by adjustment
Portion's supply voltage value adjusts the temperature of electric heating piece 8.
For magnetic material (iron-cobalt-nickel) test specimen, the present invention directly can be adsorbed in foil gauge mounting position；For thin-walled
Workpiece, thin-wall part both sides are pressed in by the present invention in pairs, are acted on by the attraction of magnet and compressed, while during force, thin-wall part
Bidirectional stress will not be deformed.
Force size is changed by the precession amount for changing power bar, thrust bearing is set in device, needed for reduction rotary force rod
Power, while rubber blanket will not rotate during ensureing power bar precession, and due to the pliability of rubber itself, make uniform force application.
Electric heating piece in device, can adjust temperature by changing the size of input voltage.The present invention can meet the pressure of high temperature jelly solidification
Power and temperature conditionss, and protect thin-wall part not acted on by unidirectional force, device is simply easily operated, is applicable to foil gauge and is similar to
The attachment of sensor and solidification process of adjusting.
Hereinafter, it is specifically used embodiment.
Embodiment 1：
Embodiments of the invention 1 such as Fig. 5 show, magnetic work 15 is directly adsorbed in by the attraction of 13 magnet 5 of the invention
Surface, the adjustment power of rotating end cap 1 bar 3 and the screw thread of pedestal 4, make the attraction of magnet 5 reach test requirements document.Because bearing 11
Frictional force is smaller, and the power of rotating end cap 1 is smaller, and magnet 5 will not rotate with the rotation of end cap 1 and power bar 3.
Magnet 5 makes power be uniformly applied to high temperature jelly 14 by super heated rubber pad 7, the peripheral hardware electricity that change is connected with electrode 9
