The disclosed anchor clamps that are applicable to thin slice surface of steel plate metallographic sample preparation of the utility model; Comprise pedestal, lifting bolt, bolt and magnetic base station; Pedestal is provided with the center screw that runs through pedestal, and the positioning screw hole that is provided with on the pedestal runs through from sidewall and is communicated to center screw, and lifting bolt is connected on the pedestal through center screw; Bolt is connected on the pedestal through positioning screw hole, and the magnetic base station is fixed on lifting bolt one end top.The disclosed anchor clamps of the utility model have simple structure; Utilize the ferromagnetism of iron and steel; The thin slice steel plate sample that uses the magnetic base station to treat to grind is implemented preliminary fixing, utilizes bolt that lifting bolt is implemented the location again, has avoided effectively that sample is subjected to displacement because of forced vibration in the process of grinding; And influence the precision that grinds of sample, thereby influence the preparation quality of sample.
The disclosed a kind of improvement that is applicable to the anchor clamps of thin slice surface of steel plate metallographic sample preparation of the utility model is provided with sample well in the center screw place on the pedestal of anchor clamps.This improvement is through being provided with sample well; Sample to be ground is placed in the sample well, avoided the displacement of sample in the process of grinding effectively and depart from, utilize sample well further restriction and fixing of the sample on the pedestal; Avoid deviation position effectively, improved precision and yield rate that sample grinds.
The disclosed anchor clamps of the utility model have simple structure; Utilize the ferromagnetism of iron and steel, the thin slice steel plate sample that uses the magnetic base station to treat to grind is implemented preliminary fixing, utilize again bolt to lifting bolt implement location and sample well on pedestal to the location of sample with fixing; Avoided effectively that sample is subjected to displacement because of forced vibration in the process of grinding; And influence the precision that grinds of sample, thus influence the preparation quality of sample, that has improved sample effectively grinds efficient and yield rate.

Embodiment
Below in conjunction with accompanying drawing and embodiment, further illustrate the utility model, should understand following embodiment only be used to the utility model is described and be not used in the restriction the utility model scope.
As depicted in figs. 1 and 2; The disclosed anchor clamps that are applicable to thin slice surface of steel plate metallographic sample preparation of the utility model comprise pedestal 2, lifting bolt 1, bolt 3 and magnetic base station 4, and pedestal 2 is provided with the center screw 5 that runs through pedestal 2; The positioning screw hole 6 that is provided with on the pedestal 2 runs through from sidewall and is communicated to center screw 5; Lifting bolt 1 is connected on the pedestal 2 through center screw 5, and bolt 3 is connected on the pedestal 2 through positioning screw hole 6, and magnetic base station 4 is fixed on lifting bolt 1 one end tops.The disclosed anchor clamps of the utility model have simple structure; Utilize the ferromagnetism of iron and steel; The thin slice steel plate sample that uses the magnetic base station to treat to grind is implemented preliminary fixing, utilizes bolt that lifting bolt is implemented the location again, has avoided effectively that sample is subjected to displacement because of forced vibration in the process of grinding; And influence the precision that grinds of sample, thereby influence the preparation quality of sample.
As a kind of preferred, be provided with sample well 7 in center screw 5 places on the pedestal 2 of anchor clamps.Sample well can be circular, oval, square, pentagon, hexagon, eight distortion and other polygon or bent limit shape; Through sample well is set; Sample to be ground is placed in the sample well, avoided the displacement of sample in the process of grinding effectively and depart from, utilize sample well further restriction and fixing of the sample on the pedestal; Avoid deviation position effectively, improved precision and yield rate that sample grinds.
Thin slice steel plate to be detected is cut into the sample that adapts with sample well size and profile; Place it on the magnetic base station 4; Utilize magnetic that the bonding effect of sample is finely tuned control to the position and the shape of sample on pedestal 2; Be beneficial to the grinding of sample, regulate lifting bolt 1 then and make sample be beneficial to grinding of the face of grinding, regulate 3 pairs of lifting bolts 1 of bolt and position at the suitable thickness of pedestal 2 protrusions; To prevent lifting bolt 1 occurrence positions skew in the process of grinding, scrap thereby cause grinding sample.Lifting screw 1 can be per sample the thickness up-down adjustment, bolt 3 mainly plays the effect of fixed elevated bolt, lifting bolt moves up and down when preventing grind away.During grind away, the position of lifting screw 1, pedestal 2 and sample relation is lower than pedestal 2 surfaces for lifting screw 1, and the face of grinding of sample is higher than pedestal 2; The pedestal that its objective is can play the effect of baffle plate, and sample is dished out when preventing grind away, and the face of grinding of sample is higher than pedestal; So just only can be ground to sample; And be unlikely to be ground to anchor clamps, in the grind away process, can be at any time per sample thickness situation regulate the height of lifting bolt.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme of being made up of above technical characterictic combination in any.
The disclosed anchor clamps of the utility model have simple structure; Utilize the ferromagnetism of iron and steel, the thin slice steel plate sample that uses the magnetic base station to treat to grind is implemented preliminary fixing, utilize again bolt to lifting bolt implement location and sample well on pedestal to the location of sample with fixing; Avoided effectively that sample is subjected to displacement because of forced vibration in the process of grinding; And influence the precision that grinds of sample, thus influence the preparation quality of sample, that has improved sample effectively grinds efficient and yield rate.
