DETAILED DESCRIPTION

[0024] The embodiments of the utility model are described in detail below, and the examples of the embodiments are represented in the drawings, wherein the same or similar symbols represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as limiting the utility model.

[0025] Embodiment 1

[0026] Reference Figures 1 to 5 , the metallographic grinding tool fixture described in the embodiment includes clamping tool 1 and rotating base plate 2, clamping tool 1 includes magnetic base 101, switch 102 and clamp, switch 102 controls magnetic base 101 to pass through magnetism and break magnetism, rotating base plate 2 includes metal seat 21 and polishing disc 22, polishing disc 22 is embedded in metal seat 21, magnetic base 101 is adsorbed on metal seat 21 after passing through magnetism, and the clamping end of clamp is located above polishing disc 22.

[0027] Magnetic base 101 can be controlled to pass through magnetism or break magnetism through switch 102, and can be adsorbed on metal seat 21 after passing through magnetism, so that polishing disc 22 grinds metallographic products. One polishing disc 22 can correspond to multiple groups of same or different clamping tools 1, and multiple clamping tools 1 can be installed and removed at any time, with high flexibility.

[0028] As a preferred mode, as Figure 4As shown, the magnetic base 101 includes two groups of semi-arc-shaped magnetic blocks 1011 and two groups of non-magnetic blocks 1012, the two ends of the magnetic blocks 1011 are connected with another group of magnetic blocks 1011 through the two groups of non-magnetic blocks 1012 respectively, and the two groups of semi-arc-shaped magnetic blocks 1011 and the two groups of non-magnetic blocks 1012 form a hollow cavity after being connected. The switch 102 includes a switch base 1021 and a cylindrical magnet 1022, the north and south poles are located at the two ends of the diameter of the cylindrical magnet 1022, and the switch base 1021 is fixedly connected with the cylindrical magnet 1022 at one end along the length, and the cylindrical magnet 1022 is inserted into the cavity.

[0029] When the switch base 1021 is rotated and the north and south poles of the cylindrical magnet 1022 are directed to the magnetic blocks 1011, the magnetic base 101 can be magnetized because the magnetic blocks 1011 are magnetized, so that the magnetic base 101 can be adsorbed on the metal seat 21. Conversely, when the switch base 1021 is rotated and the north and south poles of the cylindrical magnet 1022 are directed to the non-magnetic blocks, the magnetic base 101 is not magnetized because the non-magnetic blocks 1011 are not magnetized. Therefore, when polishing is needed, the clamp clamps the metallographic product, and the clamping tool 1 is placed on the rotating base 2 at a suitable position, so that the metallographic product is in contact with the polishing disc 22, and then the switch base 1021 is rotated to magnetize the magnetic base 101 and adsorb it on the metal seat 21.

[0030] As another preferred mode, as shown in the figure, Figure 5 The magnetic base 101 includes a mounting shell 1014, and an electromagnet 1013 is mounted in the mounting shell 1014. The switch 102 includes a power-on switch 1023, and the electromagnet 1013 is connected with the power-on switch 1023 in series and then connected with an external power supply.

[0031] When the power-on switch 1023 is rotated to energize the electromagnet 1013, the electromagnet 1013 is magnetized and adsorbed on the metal seat 21. Conversely, when the power-on switch 1023 is rotated to de-energize the electromagnet 1013, the magnetic base 101 can be easily separated from the metal seat 21.

[0032] The magnetic base 101 is provided with a mounting seat 103, and the clamp includes a clamp tail 105, a first clamping plate 107 and a second clamping plate 108. The first clamping plate 107 and the second clamping plate 108 are rotatably connected to form a clamping angle for clamping the product.

The inner walls of the first clamping plate 107 and the second clamping plate 108 are provided with toothed gears 109 in the form of a rack, the toothed gears 109 are away from the clamp tail 105, and the plate-shaped metallographic product is clamped between the toothed gears 109. The toothed gears 109 limit the position of the product to prevent the product from rotating under the rotation of the polishing disc 22, thereby increasing the stability of polishing.

[0033] An angle adjusting assembly is installed between the first clamping plate 107 and the second clamping plate 108 for locking the size of the clamping angle, and the first clamping plate 107 and the second clamping plate 108 are fixed relative to each other through the angle adjusting assembly. Since the widths of different products are different, the corresponding clamping angle is adjusted, and after clamping, the first clamping plate 107 and the second clamping plate 108 are fixed relative to each other through the angle adjusting assembly to limit the product.

[0034] Preferably, the angle adjusting assembly comprises an adjusting groove 110 penetrating the first clamping plate 107 or the second clamping plate 108 and a fastener, the fastener abutting against the inner wall of the second clamping plate 108 or the first clamping plate 107 through the adjusting groove 110, and the fastener limits the increase of the clamping angle between the first clamping plate 107 and the second clamping plate 108. The fastener comprises an adjusting rod 111 and a nut 112, the adjusting rod 111 abutting against the inner wall of the second clamping plate 108 or the first clamping plate 107 through the adjusting groove 110, and then the nut 112 is screwed to abut against the outer wall of the first clamping plate 107 or the second clamping plate 108 to limit the outward rotation of the first clamping plate 107 or the second clamping plate 108, so as to prevent the clamping from loosening and ensure the stability of clamping.

[0035] The clamping tool 1 comprises a height adjusting assembly, and the clamp is adjustably installed at different heights of the mounting seat 103 through the height adjusting assembly. The different heights of the clamp can be applied to metallographic products of different lengths.

[0036] Preferably, the mounting seat 103 is a hollow support, and a through groove is provided on each of the two side walls of the mounting seat 103 along the length direction of the clamp, the length of the through groove is consistent with the height direction of the mounting seat 103, and the length of the through groove is greater than the thickness of the clamp.

A stop block 106 is installed on the side wall of the mounting seat 103 away from the first clamping plate 107, and the stop block 106 is fixedly connected with the clamp tail 105 through the through groove. The stop block 106 is used for keeping the stability of the clamp, and the clamp is raised or lowered by rotating the lifting rod 104.

[0037] Working principle: rotate the nut 112 outward, place the product between the teeth 109, adjust the angle between the first clamping plate 107 and the second clamping plate 108 until the product is clamped, then rotate the nut 112 inward until the nut 112 abuts against the clamping plate, so as to fix the product; then rotate the lifting rod 104 to adjust the height of the clamp, so that when the magnetic base 101 is placed on the metal base 21, the product is higher than the metal base 21, adjust the height of the clamp, place the magnetic base 101 on the metal base 21 at a suitable position, so that the product is located directly above the polishing disc 22, rotate the switch 102 to make the magnetic base 101 magnetize, and the magnetic base 101 tightly adheres to the metal base 21 after being magnetized, finally adjust the lifting rod 104 to make the bottom of the product contact the polishing disc 22 for polishing.
