Electronic Coating adhesion test instrument
Technical field
The utility model relates to the test unit field, particularly a kind of electronic Coating adhesion test instrument.
Background technology
Coating adhesion test instrument is to measure the device of paint film adhesion performance through drawing the circle method of loci.The structure of existing Coating adhesion test instrument is generally: be made up of support, frame, horizontal movable base, stroke circular knitting machine structure and driving mechanism; At frame upper surface horizontal movable base is installed; At support one end frame is installed, on the cantilever of frame, installs and draw the circular knitting machine structure, move through the drive mechanism horizontal movable base; Drive a stroke circular knitting machine structure simultaneously and draw circle, on measured workpiece, mark spiral trajectory.The driving mechanism of existing test instrument is the hand driving mechanism mostly, promptly drives horizontal movable base and draws the action of circular knitting machine structure through the gear train in the rack-mounted rocking handle drive chassis.Existing hand test instrument exists automaticity low, awkward problem.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of automaticity high, electronic Coating adhesion test instrument easy to use.
It is to adopt following technical scheme to realize that the utility model solves its technical matters:
A kind of electronic Coating adhesion test instrument; Comprise support, frame, horizontal movable base, draw circular knitting machine structure, pallet body; At frame upper surface horizontal movable base is installed, this horizontal movable base bottom engagement is equipped with screw drive mechanism, installs frame at support one end; On the cantilever of frame upper end, install and draw the circular knitting machine structure; This stroke circular knitting machine structure is driven through gear drive by rotation axis, the top tray mechanism of platen mechanism, and it is characterized in that: the bottom in frame is equipped with motor; Thereby the output shaft of this motor stretches to frame inside and moves with drive screw gear train interlock driving horizontal movable base, thereby the output shaft of this motor is drawn the rotation of circular knitting machine structure with rotation axis interlock driving simultaneously.
And described motor output shaft is through belt wheel gear train and screw drive mechanism interlock.
And described motor output shaft is through belt wheel gear train and rotation axis interlock.
Advantage of the utility model and beneficial effect are:
The utility model is simple in structure, and design science is reasonable, adopts motor-driven mode to realize the Coating adhesion test instrument action; Have the automaticity height, easy and simple to handle, efficient is high; The advantage that degree of accuracy is high is a kind of electronic Coating adhesion test instrument that has than high innovation character.

Embodiment
Through specific embodiment the utility model is done further to detail below, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of electronic Coating adhesion test instrument; Comprise support 1, frame 6, horizontal movable base 2, draw circular knitting machine structure, pallet body 3, at frame upper surface horizontal movable base is installed, this horizontal movable base bottom engagement is equipped with screw drive mechanism 14; Install frame at support one end; On the cantilever 5 of frame upper end, install and draw the circular knitting machine structure, draw the circular knitting machine structure and be made up of vertical shaft 8, measuring head 4, vertical shaft is installed in cantilevered head through spring 9; Vertical shaft bottom installation testing head installs the eccentric cutter of drawing at the lower surface of measuring head.The vertical shaft of this stroke circular knitting machine structure drives the top tray mechanism of platen mechanism by rotation axis 11 through gear drive 10.Its innovation part is: in the bottom of frame motor 7 is installed; Thereby the output shaft of this motor stretches to frame inside and drives horizontal movable base with the interlock of drive screw gear train and moves, and motor output shaft links through belt wheel gear train 13 and screw drive mechanism.Thereby the output shaft of this motor drives with the rotation axis interlock simultaneously and draws the rotation of circular knitting machine structure. motor output shaft is through belt wheel gear train 12 and rotation axis interlock.
The principle of work of this electronic Coating adhesion test instrument is:
Measured piece is placed on the horizontal movable base upper surface, on pallet, places the counterweight of testing requirements, draw the circular knitting machine structure and move down this moment; Starter motor, horizontal movable base drives measured piece and moves horizontally, and draws the circular knitting machine structure simultaneously and rotates; Thereby mark the spirality circle on the surface of measured piece, test.
