Abstract
The utility model provides a sheet grinding machine for a test room, which replaces a metal test sheet which is ground by hands and is suitable for grinding the test sheet of a coke forming machine, a corrosion and rust test and the test of other metal materials. A sheet is ground by using a linear motion mode, and the test sheet and an abrasive paper finish the processes of planishing and burnishing the test sheet in the motion with different directions and speeds and friction. A grinding box which is loaded with the test sheet can be conveniently replaced according to the specification of the test sheet, and simultaneously a plurality of test sheets can be ground.
Description
The utility model relates to a kind of machine for grinding test pieces, and the enough sand paper of particularly a kind of energy is along the machine of rectilinear direction polishing test piece.
The metal testing plate that the laboratory is used is according to different tests and analytical method, specification unlike material difference, but all must be with varigrained sand papering, polishing.People continue to use these test pieces of manual grinding always before the utility model.Manual abrasive disc is firmly inhomogeneous owing to existing, and the test piece plane behind the mill is convex, is the main cause that causes the leakage of oil of coking device test test piece end face, also causes difficulty to repolishing of test piece behind the burn into corrosion test.Big, time-consuming, the effort of abrasive disc experimenter labour intensity, efficient are low by hand, and the manual abrasive disc test piece surface roughness that grinds that varies with each individual differs greatly, and bring unnecessary error for various tests.
The purpose of this utility model is the machine for grinding test pieces that a kind of electromechanical integration will be provided, and it is the instead of manual abrasive disc efficiently, and can grind surfacing, the test piece of the consistent Pass Test standard-required of roughness.
The purpose of this utility model is achieved in that one can parallel reciprocating push trolley be being loaded and is with elastomeric test piece, the test piece flour milling up, there are ventricumbent sand paper of sand and pressing plate in its top, and pressing plate and elastomeric interaction have determined test piece and sand paper frictional force at the volley.When test piece is with the flatcar transverse movement, sand paper is also along with pressing plate is being done vertically slowly mobile, can make coated abrasive surface be gone up (the push trolley width has only half of sand paper width) like this by the test piece mill, and the sand grains that is worn away is rolled out from the test piece both sides, can not rest on and cause surface scratch in the test piece, test piece and sand paper reach and polish the purpose of polishing test piece in the reciprocating motion of both direction and friction.
Specifically be exactly: a kind of metal testing plate sanding machine, this machine is made up of upper strata abrasive disc and lower floor's power transmission control two parts, it is characterized in that:
A. upper strata abrasive disc part: the flatcar of straight line moving (6) is loading grind box (10) test piece (11) reciprocating and friction below sand paper (12), does simultaneously to indulge and vertically moves back and forth with stretch tight sand paper (12) on pressing plate (14) of press strip (13).
B. lower floor's power transmission control section: decelerator (2) connects by sprocket wheel (15) and drags leading screw (16) and pressing plate (14), reversing switch (18) and control circuit (19) are realized motor (1) rotating, pressing plate (14) can be moved back and forth, and decelerator (2) connects eccentric wheel (3), connecting rod (4) and rocking arm (5) drive flatcar (6) simultaneously and do straight reciprocating motion on guide rail (8).
Said test piece (11) is placed on plastics grind box (10) lining of matrix, and grind box (10) degree of depth is 1/2 of test piece (a 11) thickness, cushions the bipeltate or the sponge of 10 millimeters thick under the grind box (10).
There is the bearing (7) of four band dust caps to do wheel below the said flatcar (6), recessing (9) length of flatcar (6) and width are less than the length and the width of 1/2 sand paper (12), 3-8 grind box (10) and test piece (11) can be adorned in recessing (9) lining, the reciprocating speed of flatcar (6) on guide rail (8) 70 times/minute.
Said sand paper (12) is tightened in flute profile press strip (13) on the pressing plate (14) of writing board shape, 230 * 280 millimeters of sand paper (12) specifications, and the vertically speed of moving back and forth of sand paper (12) and pressing plate (14) is 0.8-1 time/minute.
The utility model can substitute artificial polishing test piece, and surfacing, high conformity, and the examination of 3-8 piece is slept because machine can be polished simultaneously at every turn, so grind high many of efficient than artificial at every turn.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof:
Fig. 1 is the oblique view of the utility model concrete structure;
Fig. 2 is a basic circuit diagram of the present utility model.
With reference to Fig. 1, Machinery Design becomes double-deck overall structure, the upper strata is the abrasive disc main part, lower floor is a power and control part, drive eccentric wheel (3) by motor (1) through decelerator (2), connecting rod (4); rocking arm (5) mechanism; will rotatablely move becomes the swing of low speed; rocking arm (5) push trolley (6) of ining succession; flatcar (6) promptly with 70 times back and forth/minute the speed rectilinear motion; be to reduce resistance and guarantee the flatcar rectilinear motion; the wheel that flatcar (6) has four bearings (7) to make is gone up at guide wheel (8) and rolled, and a plurality of plastics grind boxes (10) that elastomeric material is posted in the bottom surface are housed in flatcar (6) recessing (9).This grind box (10) can be made different sizes according to test piece (11) size.Adorning test piece (11) in the grind box (10), placed up by flour milling, the ventricumbent sand paper of one sand (12) is arranged below them, be tightened on the flat clamp (14) with press strip (13), this plate (14) left side is to have the leading screw (16) of sprocket wheel (15) transmission to connect, this plate (14) is raised to the left, be convenient to change sand paper (12), main is leading screw (16) driving pressing plate (14) and sand paper (12) with 0.8-1 time back and forth/minute speed do to move longitudinally.There are two reversing switches (18) at leading screw support (17) two ends, by control circuit (19), finish the rotating of motor (1), just make the leading screw (16) can rotating, have realized the reciprocating motion of pressing plate (14) and sand paper (12).
With reference to Fig. 2, for user's electricity consumption convenience, adopt single-phase starting motor, this motor must wait rotor to stop in the rotating commutation, could change the mode of connection that starts winding, change motor rotation direction, otherwise commutation is failure just, and produces very big spark, causes relay contact to ablate.For avoiding the generation of this situation, the utility model has designed two on-delay circuit control motor positive and inverses, this delay circuit can be delayed time for 1 second when motor commutation, the wait rotor stops, connect the relay to another direction running again, this control circuit is known for a person skilled in the art.
