Embodiment
Describe the present invention for the ease of it will be appreciated by those skilled in the art that below in conjunction with embodiment and accompanying drawing:
Shown in accompanying drawing 1,2, the scheme that present embodiment disclosed is used for resistance strain plate is carried out the device of automatic resistance trimming, is important equipment during resistance strain plate is produced.
This equipment comprises support 1, is provided with four legs 11 below support 1, at the upper surface of support 1 workbench 2 is installed, and workbench 2 is used for fixing resistance strain plate to be revised 3.What adopt for the correction of resistance strain plate 3 resistance is grinding head 4 polishings, and this grinding head 4 is an absorbent cotton system, and is coated with abrasive pastes.During polishing, grinding head 4 is directly deleted a parts and is carried out grinding by being pressed in resistance strain plate 3.
Grinding head 4 is installed on the output shaft of a motor 5, and the rotation by motor 5 drives the action of polishing of grinding head 4 high speed rotating.Motor 5 is fixed in a dozen grinding wheel feed mechanisms 7, when needs carry out grinding, this mechanism's CD-ROM drive motor 5 moves down perpendicular to workbench 2, makes grinding head 4 contact the action of polishing with resistance strain plate 3, moves on this mechanism's CD-ROM drive motor 5 and the grinding head 4 after polishing is finished.
This grinding head feed mechanism 7 comprises a vertical fixed head 71, and vertical fixed head 71 is fixed in one and drives grinding head feed mechanism 7 with respect on the laterally mobile transverse moving mechanism 8 of workbench 2.Be fixed with the vertical motor 72 and the vertical guide 73 of all installing on the vertical fixed head 71 perpendicular to workbench 2, vertical motor 72 output shafts and 74 coaxial connections of vertical screw mandrel of vertically installing, the nut of vertical screw mandrel 74 and the slide block of vertical guide 73 are affixed, and the motor 5 that grinding head 4 is installed is directly fixed on the slide block of vertical guide 73.By vertical motor 72 rotations, drive vertical screw mandrel 74 forward and backwards, thereby motor 5 is moved along vertical guide 73.
In order in polishing, to realize detection to resistance strain plate 3 resistance, the a pair of probe 6 that contacts with solder joint on the resistance strain plate 3 of being used for also is installed below vertical fixed head 71, two probes, 6 mutual insulatings, and be series in the resistance detecting circuit, include display screen in the resistance display circuit, be used to detect and show the resistance value of the resistance strain plate that detects 3.In order to make probe 6 realize moving with contacting of resistance strain plate 3 solder joints with disconnection, by movable axis one probe base 61 is installed in vertical fixed head 71 bottoms, probe 6 is fixed on the probe base 61.And, near probe base 61 positions one electromagnet 62 that repels probe base 61 is installed also at vertical fixed head 71, when electromagnet 62 when electric, repulsion mutually between electromagnet 62 and the probe base 61.Initial condition, electromagnet 62 off-positions, because probe base 61 rear portions are equipped with an extension spring 63, under the effect of spring 63 power, probe 6 presses down and contacts with resistance strain plate 3 solder joints, this resistance strain plate 3 is carried out resistance measurement, after measurement and resistance correction were finished, electromagnet 62 got electric repulsion probe base 61, promotes probe base 61 probe 6 is upturned, probe 6 is contactless with resistance strain plate 3 solder joints, carries out work so that switch to down a slice strain gauge.
Realize vertically moving in order to realize that grinding head 4 and probe 6 can be crossed, crosswise fixed plate 81 is fixed in one and drives on the longitudinal moving mechanism 9 that transverse moving mechanism 8 integral body vertically move, this mechanism comprises vertical motor 91 that is directly fixed on the support 1 and two longitudinal rails 92 that lay respectively at workbench 2 both sides and vertically install, one contour holder 94 all is installed on the slide block of longitudinal rail 92, vertical motor 91 output shafts and 93 coaxial connections of vertical screw mandrel of vertically installing, vertically the nut of screw mandrel 93 is fixed in the holder 94, and the crosswise fixed plate of transverse moving mechanism 8 is fixed on two holders 94.
In order to realize automatic control, above-mentioned each parts are all by governor circuit control, and resistance detecting circuit also connects with governor circuit, realize the co-ordination of whole device.
During operation, resistance strain plate semi-finished product that at first will be to be revised are fixed on the workbench 2, and its fixed form can adopt multiple mode, as absorption fixed form, anchor clamps fixed form etc.After fixing fully, the starting switch button, grinding head 4 and probe 6 move to a wherein resistance strain plate 3 tops of reservation, electromagnet 62 outages, probe 6 moves down and contacts with these resistance strain plate 3 solder joints, when resistance detecting circuit shows that resistance is lower than set point, governor circuit is controlled 7 actions of grinding head feed mechanism automatically, driving grinding head 4 moves down and contacts with this resistance strain plate 3, motor 5 actions simultaneously drive grinding heads 4 rotations and this resistance strain plate 3 is deleted a position carry out grinding, and the resistance that shows up to resistance detecting circuit is to subscribing within the acceptability limit.Move on the grinding head feed mechanism 7 then, grinding head 4 breaks away from resistance strain plate 3, and while electromagnet 62 gets electric, and probe 6 upwarps with solder joint and breaks away from.Transverse moving mechanism 8 moves under the control of governor circuit afterwards, grinding head 4 and probe 6 are moved to another one wait to revise the resistance strain plate top, repeat above-mentioned action, finish up to whole correction of same row's resistance strain plate, longitudinal moving mechanism 9 actions then, grinding head 4 and probe 6 are moved to next row revise, finish until all corrections.In grinding process, if the resistance no change can conclude that then this resistance strain plate damages.
The operating path of above-mentioned transverse moving mechanism 8 and longitudinal moving mechanism 9 can be set as required, both can revise by row, also can revise by row, does not limit at this.Present embodiment need to prove for one of preferable implementation of the present invention, and any conspicuous replacement all belongs to the infringement trip and is all within protection range of the present invention under the prerequisite that does not break away from the present invention's design.
