Description

TECHNICAL FIELD

[0001] The utility model relates to the field of metallographic sample polishing, especially to a polishing device for fine copper wire metallographic inlaid sample. BACKGROUND

[0002] In the process of copper wire temperature process control research, the metallographic structure of fine copper wire needs to be observed and analyzed. The diameter of fine copper wire is very small, so the copper wire needs to be inlaid before polishing, polishing and etching. Generally, the sample and bakelite powder are put into an inlaying machine, the bakelite powder is melted by heating, and then the sample and the bakelite powder are tightly combined by pressure.

[0003] Through investigation and statistics, it is found that the general metallographic sample polishing method is performed by an operator holding the sample. The operator needs to press the sample on the high-speed rotating grinding disc with his hand. Because the sample size is small, the fingers will be tired if the pressing time is too long, the sample is easy to fly out of the grinding disc, and the finger part is easy to contact the grinding disc during pressing, causing finger injury, which has a certain risk. When polishing is finished, the sandpaper on the grinding disc needs to be replaced with polishing cloth, and the polishing paste needs to be evenly applied on the polishing cloth, and then the sample needs to be pressed on the part with the polishing paste for polishing. When the polishing paste is consumed, the grinding and polishing machine needs to be turned off, the polishing paste needs to be evenly applied again, and then the sample can be polished, which is complicated. This traditional polishing method not only has a certain risk, but also has low efficiency. UTILITY MODEL CONTENTS

[0033] (Example 1)

[0034] As Figs. 1-2 shown in the fine copper wire metallographic inlay sample polishing device, including clamping part 1, paste applying part 2 and handheld part 3. The bottom of the clamping part 1 is provided with a clamping space with adjustable depth and horizontal direction spacing, which is used to meet the clamping requirements of metallographic inlay samples of different sizes. The handheld part 3 is arranged at the top of the clamping part 1, which is convenient for the operator to hold and operate, and contacts the grinding disc. The paste applying part 2 is arranged at the side of the clamping part 1, which includes a paste storage part 2-1 installed on the clamping part 1 with adjustable height, used for storing polishing paste. A strip-shaped groove is formed in the bottom of the paste storage part 2-1, and a rolling shaft 2-2 is arranged in the strip-shaped groove and rotates horizontally along the length direction of the strip-shaped groove. By reasonably designing the spacing between the rolling shaft 2-2 and the two sides of the strip-shaped groove, it is ensured that the paste will not flow to the outside under the action of tension when the rolling shaft 2-2 is static, and the polishing paste stored in the paste storage part 2-1 can be applied to the polishing cloth under the rotation of the rolling shaft 2-2. The design of the spacing belongs to a relatively mature existing technology, which will not be described here. As a handheld auxiliary tool, it reduces the operation difficulty of copper wire metallographic structure polishing and the probability of operator injury by combining the application of polishing paste on the basis of auxiliary polishing, greatly improving the work efficiency of polishing and polishing samples.

[0035] Specifically, the clamping part 1 is provided with a through channel, the bottom of the hand-held part 1 is inserted into the channel, and the bottom of the hand-held part 1 is threadedly connected with the upper part of the channel.

A strip-shaped groove is formed in the bottom of the second storage part 2-1-2. The needle tube-shaped polishing paste can be directly inserted into the first storage part 2-1-1 for use, avoiding spilling outside when the polishing paste is squeezed into the paste storage part, keeping clean, and quickly replenishing by replacing the needle tube-shaped polishing paste, which is more convenient to operate. The side edge of the clamping part 1 is fixedly installed with a fixed plate 5. The middle part of the fixed plate 5 is provided with an arc-shaped convex part 5-1 which is matched with the outer wall of the first storage part 2-1-1. The arc-shaped convex part 5-1 is provided with a locking screw 6 which is abutted and locked with the first storage part 2-1-1. When the locking screw 6 is loosened, the paste storage part can be adjusted. The arc-shaped convex part 5-1 is used as a guide to ensure that the paste storage part 2-1 moves in the vertical direction, avoids tilting, ensures that the rolling shaft at the bottom is completely in contact with the polishing cloth, increases the application area, and improves the application efficiency.
