Problems solved by technology

Among them, due to the heavy workload of manual grinding, only one specimen can be ground at a time, and the efficiency is low. The quality of grinding depends on human factors, which cannot guarantee the uniform grinding quality of each metallographic test piece, thus affecting the quality of the metallographic structure. Observation effect; the purchase cost of existing machine grinding equipment is high, and a complete set of auxiliary equipment such as mosaic machine and cutting machine is required for the grinding of thin plate samples. Slightly larger, it is difficult to inlay, and the scope of application is limited

Embodiment 1

[0045] An automatic grinding and polishing device for metallographic test pieces, which is characterized by comprising a clamp A1, a bottom plate 2, a sliding rod 3, a screw 4, a clamp B5, a mounting plate 7 and a stepping motor 10.

[0046] The stepping motor 10, two bearing seats 203 and four vertical plates 202 are fixedly mounted on the upper surface of the bottom plate 2. The four vertical plates 202 support two parallel sliding rods 3. Between the two sliding rods 3 is a lead screw 4. Bearings supported by the bearing seat 203 are installed on both ends of the screw 4. After one end of the screw 4 passes through the inner ring of the bearing, it is connected to the rotating shaft of the stepping motor 10 through a coupling. Sandpaper is laid on the upper surface of the bottom plate 2.

[0047] The mounting plate 7 is supported above the bottom plate 2 by two sliding rods 3. The screw nut 402 of the screw 4 is fixedly connected to the lower surface of the mounting plate 7....

Embodiment 2

[0053] The main structure of this embodiment is the same as that of Embodiment 1. Furthermore, the upper cover 104 is connected to the upper end of the hollow optical shaft 102 by a screw 11041.

[0054] The upper end of the internally threaded shaft sleeve 106 is connected to two limiting blocks 109 by screws II1091. The limiting block 109 blocks above the upper cover 104.

[0055] The upper end of the movable chuck 108 is a boss 1084 embedded in the lower end of the hollow optical shaft 102. Four hemispherical grooves 1081 are evenly distributed on the side wall of the boss 1084. The side wall of the hollow optical shaft 102 has a threaded through hole 1022. A ball plunger 107 is inserted into the threaded through hole 1022. One end of the ball plunger 107 enters the hemispherical groove 1081, thereby connecting the movable chuck 108 and the hollow optical shaft 102 together.

[0056] The outer side wall of the hollow optical axis 102 has a strip guide groove 1021 perpendicular...

Embodiment 3

[0062] This embodiment discloses an environmentally friendly grinding method for metallographic test pieces based on the device described in embodiment 2, characterized in that:

[0063] 1) Prepare metallographic test piece A13 and / or metallographic test piece B14

[0064] The metallographic test piece A13 is a thin sample or a square sample.

[0065] The metallographic test piece B14 is a sheet-shaped sample.

[0066] 2) First, fix 300# sandpaper on the upper surface of the base 2, and ensure that the sandpaper is flat and free of wrinkles.

[0067] 3) Install metallographic test pieces.

[0068] Place the metallographic test piece A, change its expansion and contraction by rotating the clamping screw 101 to realize the clamping process, and rotate the outer threaded shaft sleeve to make the metallographic test piece A closely fit the sandpaper.

[0069] The metallographic test piece B is placed, the amount of expansion and contraction is changed by rotating the clamping screw 502 to rea...

Abstract

The invention provides a multifunctional automatic metallographical experimental part grinding and polishing device and an environment-friendly grinding method. The device partially comprises a clampA, a bottom plate, a slide bar, a lead screw, a clamp B, a mounting plate and a stepping motor. The automatic grinding device can guarantee the grinding quality of a metallographical experimental parteffectively and can grind test pieces of different thickness or grind various test pieces simultaneously, so that the work efficiency is improved, the work strength is reduced, and influence of humanfactors to the grinding quality is reduced. The device has the characteristics of being free of insertion and water spraying to the device and has the characteristic of being green and environment-friendly when grinding a test sample.

Description

Technical field [0001] The invention belongs to the technical field of mechanical devices, and relates to an automatic grinding device, an assembly process and a use method for metallographic test pieces. Background technique [0002] In production, the microscopic information such as the evolution law of the material's metallographic structure and the grain size is of great significance for us to grasp the quality and reliability of the material. To study the number, size, distribution and morphology of the metallographic structure of the material, it is necessary to grind multiple sets of metallographic test pieces. At present, there are mainly two methods of metallographic grinding: manual grinding and machine grinding. Among them, manual grinding can only grind one test piece at a time due to the heavy workload. The efficiency is low. The quality of grinding depends on human factors. It cannot guarantee the uniformity of the grinding quality of each metallographic test piece...
