Problems solved by technology

Since the material of the thin sheet sample is non-magnetic stainless steel, it cannot be fixed with the electromagnetic force of the grinder by using electromagnetic properties. When grinding, the top plate is used to withstand the thin sheet sample. The clamping is not firm, and the grinding wheel is easy to wear off during grinding. Thin-flaky samples, slow grinding of samples, low efficiency and low grinding precision
The grinding of thin workpieces is difficult, because such workpieces are easily deformed during heat treatment, and the elastic deformation is large during grinding. The increase of grinding amount tends to be serious, and the warping direction is basically concave on the side of the grinding wheel

Embodiment 1

[0038] See this example figure 1 , figure 2 versus image 3 , It includes a suction table and auxiliary devices, characterized in that: the suction table is a suction table 18 including an iron bottom plate 19 and a vacuum suction cup 36, and the auxiliary device is a vacuum pump device 1; a suction table is installed on the suction table 18 The box 20, the suction table box 20 is fixed on the iron bottom plate 19, an outer mounting plate 32 and two handles 14 at both ends are also installed on the iron bottom plate 19, and the leak-proof ball valve 29 is fastened on the outer mounting plate 32. The top plate 38 is used as the work surface of the grinding parts. On the left side of the top plate 38, the horizontal clamping plate 21 and the two vertical clamping plates 22 are fastened by countersunk screws. At both ends of the clamping plate 21, a clamping groove 37 is formed between the two longitudinal clamping plates 22, and the width of the clamping groove 37 is greater than...

Embodiment 2

[0043] The difference between this embodiment and the first implementation of the suction table is that three vacuum suction cups 50 for impact plates are installed in the suction table box 20, and the top plate 38 of the suction table box 20 has three suction cup through holes 49, and each impact plate uses vacuum. The upper end of the suction cup 50 is inserted into the corresponding suction cup through hole 49 (one suction cup through hole 49 is inserted), and a four-way joint 47 is installed in the suction table box 20, and three of the joints are connected by a short suction cup connecting pipe. 48 is connected to the impact plate with a vacuum chuck 50, and the other joint is connected to a three-way joint 27. Each impact plate uses a vacuum chuck 50 to suck one impact workpiece, and the impact plate slot 51 places three impact workpieces, see Image 6 , Others are the same as the first embodiment of the suction table.

[0044] The size of a single workpiece is 55mm in leng...

Embodiment 2

[0050] In this embodiment, the second embodiment of the suction table is used to realize the present invention. The impact workpiece is placed in the clamping slot 51 of the impact plate, and the rest is the same as the first embodiment of the suction method.

[0051] Description

[0052] The top plate 38 of the above two embodiments is required to have sufficient hardness to offset the repeated wear of a large number of samples, so its material is selected as 45 steel.

[0053] The heat treatment process is determined as quenching heat treatment, and the plan is as follows:

[0054] ⑴Quenching treatment: enter the furnace at 860℃, heat for 1 hour, and then water quench.

[0055] ⑵ Tempering treatment: Tempering in an oven at 200°C for 2 hours.

[0056] ⑶ Hardness value: 52 HRC

[0057] Vacuum pump 9

[0058] In the grinding process, a large amount of grinding wheel chips, waste materials and cooling grinding fluid are produced, and some of them will inevitably enter the vacuum pipeline. T...

Abstract

The invention relates to an adsorption method and a grinding suction table for a non-magnetic steel sheet-like sample. The adsorption method comprises the following steps: placing the suction table with an iron base plate and a vacuum chuck on an electromagnetic suction plate; placing the non-magnetic steel sheet-like sample in a clamping groove formed in a top plate of the suction table; sucking the non-magnetic steel sheet-like sample by a vacuum pump. The grinding suction table comprises a suction table body and an auxiliary device, wherein the suction table body comprises the iron base plate and the vacuum chuck; the auxiliary device is a vacuum pump device; a suction table box and a leakage-proof ball valve are mounted on the iron base plate; the clamping groove consisting of a transverse clamping plate and two longitudinal clamping plates is fastened in the top plate; a chuck hole is formed in the top plate; the adsorption end of the vacuum chuck extends into the chuck hole; the air outlet end of the vacuum chuck is connected with the vacuum pump of the auxiliary device through a filter; a buck power supply is connected to the vacuum pump. According to the adsorption method, a non-magnetic steel plate can be adsorbed; through the adoption of the grinding suction table, working procedures are simplified, and the working efficiency that a sheet-like stainless steel specimen is ground into an impact and corrosion sample is improved.

Description

Technical field [0001] The invention relates to a non-magnetic steel sheet sample grinding suction table. Background technique [0002] Since the sample needs to be firmly adsorbed and fixed in the process of grinding the non-magnetic steel sheet sample, the grinding platform is required to have good levelness, high hardness, and strong adsorption; the existing non-magnetic steel The magnetic steel sheet-like sample adsorption method is to use the electromagnetic suction disk as a grinding suction table to attract the iron top plate, and then use the iron top plate to hold the non-magnetic steel sheet-like sample, indirect adsorption and then clamping the workpiece is very weak. The suction table is an electromagnetic suction disk. After the power is turned on, the electromagnetic suction disk generates magnetic force to attract the ground workpiece. Since the material of the thin sample is non-magnetic stainless steel, it cannot be fixed by the electromagnetic properties of the...
