Abstract
The utility model relates to a clamping device for polishing the surface of a stainless steel sheet, which comprises a bottom plate for holding a stainless steel sample. The two ends of the bottom plate are provided with a clamping component for fixing the stainless steel sample on the surface of the bottom plate. The clamping device is characterized in that the clamping component comprises an upper clamping part and a lower clamping part which are mutually connected, the opposite ends of the upper clamping part and the lower clamping part are butted to form a positioning clamping groove of a shape formed by clockwise 90-degree rotation of N , the two ends of the bottom plate are respectively inserted in the positioning clamping groove and are fixedly connected with the lower clamping part through fixing components, and the stainless steel sample is arranged on the bottom plate after penetrating through the positioning clamping groove, and is fixed on the bottom plate through movable fastening components on the upper clamping part. The utility model has the advantages of simple structure, reasonable design and safe use, and can be used for fixing and clamping during polishing of the surface of the stainless steel sheet.
Description
Technical field
The utility model relates to a kind of clamping device of sample, especially a kind of clamping device that is applicable to the polishing of stainless steel thin slice specimen surface.
Background technology
The stainless steel raw material comprises composition detection in checking and accepting, and this test requirements document is carried out the grinding and polishing processing to specimen surface, makes its roughness below 0.8.Two kinds of processing methods are arranged generally speaking, the one, carry out grinding and polishing with the grinding and polishing machine and handle, treatment effect is better, but need hand-held sample to carry out grinding and polishing, dangerous, if detected model thickness is below 6.0mm, the polishing position is last (descending) surface, carries out the machine polishing so sample can't be handed; The 2nd, the mode that adopts manual rubber to polish, the polishing dynamics is little, surface treatment effect is not good, tends to cause the final detection result instability.
The existing grinding and polishing machine equipment of sensing chamber, the limit portion burr of tension test sheet is used to polish, as Fig. 3, shown in 4, it comprises fixing upper plate 6 ', lower shoe 7 ', the two ends of upper plate 6 ' and lower shoe 7 ' are connected with fixed block 10 ', 11 ', one end fixed block 10 ' is fixed by screw with upper and lower bottom plate, other end fixed block 11 ' is fixed by screw with lower shoe 7 ', be connected by connecting bolt 9 ' with upper plate, form the cavity that to place sample between upper plate 6 ' and the lower shoe 7 ', upper plate is provided with adjustable puller bolt 8 ', and form clamping device between the lower shoe 7 ', can fix sample, but the design of this clamping device is the specification at the tension test sheet, and sample can only expose its side, and its polishing position is the side of sample, this equipment can't carry out surperficial grinding and polishing work, so can not be applicable to the surperficial grinding and polishing operation of composition detection sample.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, reasonable in design, the clamping device that is used for stainless steel thin slice surface finish safe in utilization at the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of clamping device that is used for stainless steel thin slice surface finish, comprise the base plate of placing the stainless steel sample, the two ends of base plate are provided with the hold assembly that the stainless steel sample is fixed on backplate surface, it is characterized in that described hold assembly comprises continuous clamping upper and clamping bottom, described clamping upper is located clamping slot with the involutory formation of a relative end " ㄈ " type of clamping bottom, intert respectively in the clamping slot of location at the base plate two ends, fix by fixture and clamping bottom, the stainless steel sample passes the location clamping slot and is placed on the base plate, withstands on the base plate by the mobilizable secure component on the clamping upper.
As improvement, the center of described clamping bottom is provided with the installation through hole, and corresponding base plate bottom has locating hole, and clamping bottom and base plate are connected and fixed by fixture.
As improvement, described clamping upper is processed with at least one screwed hole, but fastening bolt passes the screwed hole up-down adjustment, and sample is fixed.
As improvement, the installation through hole of described clamping bottom is preferably one, and fixture is fastening interior hexagonal.
Improve, the screwed hole of described clamping upper is preferably two of symmetrical distribution again, guarantees the clamping dynamics to sample.
At last, the length of described hold assembly is slightly larger than the width of base plate, and guaranteeing the fixing test of sample, the width of described hold assembly to be to satisfy the sample location, design shortly as far as possible, with the fully exposure of surface that guarantees sample, is convenient to grinding process.
Compared with prior art, advantage of the present utility model is: the exposed side after the clamping is improved to exposed surface after the clamping, changes original four trip bolts vertically arranging into horizontal two groups each two, guaranteed the clamping force to sample.In addition for increasing the polishing area of sample as far as possible, to locate clamping part designs shortlyer, removed upper plate simultaneously, only retain base plate, guarantee the abundant exposure on tested sample surface, the utility model is simple in structure, reasonable in design, and is safe in utilization, can be used for the fixed clamp of stainless steel thin slice surface finish.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of clamping device that is used for stainless steel thin slice surface finish, comprise the base plate 3 of placing stainless steel sample 5, the two ends of base plate 3 be provided with stainless steel sample 5 be fixed on base plate 3 surfaces hold assembly 2, described hold assembly 2 comprises continuous clamping upper 21 and clamping bottom 22, clamping upper 21 is located clamping slot with the involutory formation of a relative end " ㄈ " type of clamping bottom 22, intert respectively in the clamping slot of location at base plate 3 two ends, the center of clamping bottom 22 is provided with the installation through hole, corresponding base plate 3 bottoms have locating hole, clamping bottom 22 is connected and fixed by hexagonal 4 in fastening with base plate 3, and clamping upper 21 is processed with two screwed holes, but fastening bolt 1 passes the screwed hole up-down adjustment, withstand on sample 5 surfaces, sample 5 is positioned, and the length of hold assembly 2 is slightly larger than the width of base plate 5, to guarantee the fixing of sample 5, the width of hold assembly 2 is to satisfy the location of sample 5, design shortly as far as possible, fully expose, be convenient to grinding process with the surface that guarantees sample 5.
During use, with hexagonal 4 in fastening that base plate 3 is fixing with hold assembly 2 earlier, and adjustment level, then unscrew 4 fastening bolts 1 of clamping upper 21 in two groups of hold assemblies 2, the stainless steel sample 5 that need are polished cuts into and base plate 3 similar sizes, is put into then on the base plate 3, need one of the polishing placement that faces up, screw fastening bolt 1 again, so just sample 5 is fixed on the base plate 3, just can carry out grinding process.
