Abstract

The utility model discloses a metallographic sample grinding machine belonging to the manufacturing technique field of mechanical grinding metallographic sample devices. The grinding machine includes a shell, a motor, flywheels, a connecting rod, a locating rod, a clamping rod, clamping blocks, an elastic steel ball, abrasive paper squashes and a piece of abrasive paper. Wherein, the shell provided with the motor inside is positioned horizontally on the working table; the flywheels are arranged on an output shaft of the motor and on the upper and the lower surface of the shell; the connecting rod is connected with the flywheels, and the other end of the connecting rod is connected with the clamping rod, and the middle part of which is provided with grooves; the grooves on both sides are jammed on the elastic steel ball on the locating rod connected with the shell; the lower part of the clamping rod is provided with a plurality of clamping blocks which clamp the metallographic sample under the clamping rod by clamping bolts; and the two abrasive paper squashes on the upper surface of the shell compress the abrasive paper face up tightly on the surface of the shell. The module grinds and proceeds straight reciprocating motion when the grinding machine is in working condition, and the grinding machine has the advantages of reasonable structure and high efficiency in grinding.

Description

The metallographic specimen grinding machine

Technical field

The utility model discloses a kind of metallographic specimen grinding machine, belongs to machinery and grinds metallographic specimen device class manufacturing technology field.

Background technology

In materials processing and research, often need carry out the metallographic composition and observe material, need to be studied material and take a sample, the material to sampling grinds a face then, and the application high-power microscope is observed the surface that grinds.Because observed surface need be polished, thereby need grind metallographic specimen.Manually grind a sample and generally need about 80 hours, cause a large amount of wastes of time.Although there is the metallurgical polishing machine to occur now, the motion that the metallurgical polishing machine is produced is a circumference, to some sample and improper.Patent 87102710.0 disclosed " metallographic-sample polisher " has adopted the motion that grinds of circumference equally, patent 92107323.2 disclosed " automatic abrasive polisher for metallographic sample " is although be that rectilinear motion grinds, but once can only grind a sample, efficient is very low.

Summary of the invention

At the deficiencies in the prior art, the utility model provide a kind of rational in infrastructure, can rectilinear motion grind, grind the high metallographic specimen grinding machine of efficient.

The utility model is achieved through the following technical solutions:

The utility model comprises housing, motor, flywheel, connecting rod, backstay, clamping bar, clamp, elastic steel ball, sand paper compressing tablet and sand paper, wherein: housing lies in a horizontal plane on the work top, motor is installed in the housing, the top and bottom that flywheel and flywheel are installed in housing are installed on the output shaft of motor, flywheel is connected with connecting rod, the other end of connecting rod links to each other with clamping bar, there is groove at the middle part of clamping bar, on the elastic steel ball on the backstay that the groove on both sides is stuck in housing is connected, the bottom of clamping bar is equipped with some clamps, clamp is clamped in the below of clamping bar by the pinching screw on it with metallographic specimen, and two sand paper compressing tablets of housing upper surface face up sand paper and are pressed in surface of shell tightly.

Described motor is that the output band slows down, and its speed is between per minute 300-800 changes.

In the middle of the described clamp is with holes, and has spring.

The utility model is specifically used motor and is produced power, the device that metallographic specimen can be ground automatically by some mechanisms.The other end of connecting rod links to each other with clamping bar by bearing pin, during application, transfers to the bearing pin that connects connecting rod and clamping bar, clamping bar is taken off and overturn, turn on pinching screw, select the adjustment piece of suitable width, the sample that will grind sandwiches successively, with the clamping bar counter-rotating, be pressed in the elastic steel ball then, put into bearing pin, turn on the screw of sand paper compressing tablet, change sand paper, the speed and the time of motor operation is adjusted in the back, grinds metallographic specimen.During the work of this grinding machine, the motor rotation drives the flywheel rotation, and flywheel drives clamping bar and does linear reciprocating motion, the sample that is pressed in below the clamping bar is formed with sand paper rub, thereby grind sample.

The beneficial effect that the utlity model has:

1, the sample that is once ground is a plurality of, and size can be different;

2, rational in infrastructure, energy rectilinear motion grind, grind the efficient height.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the utility model is adjusted the piece schematic diagram.

Wherein, 1, housing, 2, motor, 3, flywheel, 4, connecting rod, 5, backstay, 6, bearing pin, 7, clamping bar, 8, clamp, 9, pinching screw, 10, elastic steel ball, 11, the sand paper compressing tablet, 12, sand paper, 13, spring, 14, adjust piece.

The specific embodiment

Embodiment: structure as shown in Figure 1, the housing 1 of grinding machine lies in a horizontal plane on the work top, flywheel 3 is installed on the output shaft of motor 2, be installed in the top and bottom of housing 1 respectively, flywheel 3 is equipped with connecting rod 4, the other end of connecting rod 4 links to each other with clamping bar 7 by bearing pin 6, there is groove at the middle part of clamping bar 7, the groove on both sides is stuck on the elastic steel ball 10 on the backstay 5 that is connected with housing 2, the bottom of clamping bar 7 is equipped with some clamps 8, clamp 8 is clamped in the below of clamping bar 7 by the pinching screw on it 9 with metallographic specimen, and two sand paper compressing tablets 11 of housing 1 upper surface face up sand paper 12 and are pressed in housing 1 surface tightly.As Fig. 2, the big I of sample clamps by changing the size of adjusting piece 14, and spring 13 is used to regulate the distance between the clamp 7.

During the work of this grinding machine, motor 2 rotations drive flywheels 3 rotations, and flywheel 3 drives clamping bars 7 and does linear reciprocating motion, the sample that is pressed in below the clamping bar 7 is formed with sand paper 12 rub, thereby grind sample.
