Description
Technical Field
The utility model relates to a anchor clamps of polishing suitable for little volume metallographic test piece belongs to parts machining technical field.
Background
In a metallographic test, grinding and polishing are needed in the preparation process of a test piece, casting embedding or mechanical clamping is usually needed for a test piece with a small volume and an irregular shape, so that grinding and polishing are more efficient and convenient, but the most common materials of the former are epoxy resin and denture powder at present, the melting point is low, heat treatment cannot be performed, the grinding and polishing surface of the test piece can be inclined due to the irregular shape of the test piece in the manual grinding and polishing process, after the grinding and polishing are finished, the test piece is embedded in a high polymer material, the taking-out process is more complex compared with the latter, the latter can be loosened when the test piece with a small volume is ground and polished, the grinding and polishing efficiency is influenced, and a clamp suitable for the test piece with a small volume and an irregular shape is designed absolutely necessary for the test piece with a small volume and a small shape existing in.
Disclosure of Invention
The utility model aims to solve the problem that exists in the prior art, provide a anchor clamps of polishing suitable for little volume metallographic test piece, can grind through this anchor clamps and throw the in-process at the metallographic test, to the fine fixed of some irregular test pieces of small shape, difficult production is not hard up, keeps grinding and throws the plane level, improves artifical efficiency of polishing.
For solving the technical problem that exists at present above, the utility model provides a technical scheme does: the utility model provides a anchor clamps of polishing suitable for little volume metallographic test piece, includes exposed core, fixing device, skid resistant course, rubber sleeve, be equipped with the screw thread on the exposed core, be connected with fixing device through the screw thread, the last rubber sleeve that is equipped with of fixing device, the exposed core is equipped with fixed limb, be equipped with the skid resistant course on the fixed limb, still be equipped with the boss on the fixed limb.
Further, the thickness of the antiskid layer is 2-5 mm.
Furthermore, the anti-skid layer, the rubber sleeve and the bottom of the boss are all provided with anti-skid textures.
Further, the limbs are integral with the clamp end.
Furthermore, the distance between the openings of the two opposite fixed limbs is less than or equal to 10 mm.
Further, it is suitable for a cross-sectional area of 25mm2-100mm2The test piece of (1).
The utility model has the advantages as follows: the utility model discloses can be through fixed limb fine fixed when polishing little volume test piece, can not produce the rotation, can not produce relative motion to inside, keep grinding and throw the plane level, can be convenient take out the test piece, improve and grind and throw efficiency, use manpower sparingly.

Detailed Description
The invention is explained in detail by means of the figures and the examples:
combine shown anchor clamps of polishing suitable for little volume metallographic test piece of 1 ~ 3, including exposed core 1, fixing device 2, skid resistant course 3, rubber sleeve 4, exposed core 1 is last to be equipped with screw thread 5, is connected with fixing device 2 through screw thread 5, be equipped with rubber sleeve 4 on fixing device 2, establish to the fillet on one side of fixing device 2 and exposed core 1 contact, can be when rotating the swivel mount and make the test piece fixed better exert force to stationary limb 6, exposed core 1 is equipped with stationary limb 6, and stationary limb 6 and exposed core 1 are as an organic whole, utilizes the elastic deformation of metal for better stationary test piece, and two relative stationary limb 6 opening part distances are less than or equal to 10mm, can lead to stationary limb 6 to take place plastic deformation if the opening distance is too big, and then cause the damage to the anchor clamps, so the utility model is suitable for a cross-sectional area is 25mm2-100mm2The test piece of (1), be equipped with skid resistant course 3 on the fixed limb 6, skid resistant course 3 thickness is 2-5mm, still be equipped with boss 7 on the fixed limb 6, the reaction force that the boss can provide down when artifical mill is thrown makes the test piece can not produce relative motion, and skid resistant course 3, rubber sleeve 4 and boss 7 bottom all are equipped with anti-skidding texture in addition.
When the device is used, a test piece is placed on the fixing limbs, the top end of the test piece is in contact with the boss, the fixing device is rotated, the fixing limbs fix the test piece, namely, the test piece can be polished after being installed, the fixing device is rotated to the round angle to be located at the fixed end after polishing, and the test piece is taken down along the gap between the fixing limbs.
Through the above, the purpose, the detailed description and the embodiments of the present invention are right, but not limiting the protection scope of the present invention. Therefore, if the technical personnel in the field receive the inspired by the utility model, all be in the spirit of the utility model and the similar structural style and the implementation mode of design in principle, all should be in the protection scope of the utility model.
