Abstract
The utility model relates to a machining clamping device of a plate-shaped stretching sample machine tool, particularly a machining clamping device of a machine tool for machining plate-shaped stress corrosion samples. The utility model comprises a clamping device body. The middle of the upper part of the clamping device body is provided with a longitudinal square through hole which is inserted with a plate-shaped stretching sample, and one side surface of the upper part of the clamping device body is provided with a groove which is provided with a lifting movable press plate. The central axis line of the clamping device body is provided with a bottom surface of a pressing plate fastening bolt which pushes up the lifting movable press plate. The shape of the middle of the top of the clamping device body is same with the shape of the gauge length of the plate-shaped stretching sample. When the utility model is used, the sample main body is clamped by one time, the two side surfaces of the gauge length are processed, the parallelism and the symmetry of the two side surfaces of the gauge length are guaranteed, the use is convenient, and the sample machining quality is improved.
Description
The utility model relates to a kind of tabular tensile sample machine tooling anchor clamps, particularly a kind of machine tooling anchor clamps that are used for machining plate-like stress corrosion sample.
As everyone knows, tabular tensile sample geometric configuration is less, the profile of especially tabular stress corrosion sample is especially little, only is 200 millimeters, 14 millimeters and 2 millimeters respectively as length, width and thickness, and the length at middle gauge length position and width only are 30 millimeters and 3 millimeters respectively.Simultaneously, also require to limit additional machining stress man-hour adding.Processing brings great difficulty to sample for this.Usually its job operation is divided two steps: 1. take out earlier the rectangle plate of length, width and the satisfactory specimen size of thickness, i.e. sample parent from tested steel; 2. sample parent middle part is carried out the gauge length position that milling and grinding go out sample.The processing of first step is comparatively simple, and, normally use machine tool accessories flat-nose pliers clamping sample parent, a side at milling gauge length position to the processing of second step, then the sample parent is turned over turnback and again behind the clamping, the another side at milling gauge length position.This twice clamping processing sample gauge length position is difficult to guarantee the technical requirement of the gauge length position two sides depth of parallelism and symmetry.
The purpose of this utility model is to provide tabular tensile sample machine tooling anchor clamps, as long as a clamping sample parent just can be processed two sides at gauge length position, and guarantees the depth of parallelism and the symmetry of two sides, gauge length position.
For achieving the above object, the utility model adopts following technical proposals: the utility model is the same with the existing machine tool clamp for machining to include a clamp body.It is characterized in that the middle vertical square through hole that the tabular tensile sample of planting is arranged in clamp body top, and lifting movable pressing board of the fluted arrangement in one side, top; The bottom surface that a pressing plate fastening bolt roof pressure lifting movable pressing board is arranged on the clamp body central axis; Clamp body crown center position shape is identical with tabular tensile sample gauge length position shape.During use, the tabular tensile sample parent of multi-disc is inserted in vertical square through hole on clamp body top from the vertical equity direction, the fastening tabular tensile sample parent of clamping by pressing plate fastening bolt roof pressure lifting movable pressing board, clamp body is positioned on the vertical milling machine work top, but two sides with regard to milling sample marking distance position, then clamp body is positioned on the tool-grinding machine work top, just can be to the bowl-type cylindrical grinding wheel grinding of the two sides at sample marking distance position.
Above-mentioned clamp body lower side can design fluted, and the bolt head of pressing plate fastening bolt stretches in this groove, and then available wrench plate dynamic pressure plate fastening bolt makes the lifting movable pressing board compress the sample parent or unclamps.Can design lifting movable pressing board lateral surface has the gathering sill of vertical direction and a pressing plate feather key cunning to join, and the pressing plate feather key is fixed on the clamp body by two bolts, can guarantee that the lifting movable pressing board moves in the vertical direction.Can also design on the longitudinal centre line of clamp body bottom surface has keyway, uses two clamp body positioning keys of bolt in this keyway.By these two clamp body positioning keys location that is connected with the "T"-shaped groove of platen.
The utility model has following conspicuous advantage compared with prior art: use tabular tensile sample machine tooling anchor clamps of the present utility model, only need a clamping sample parent, just can process two sides at its gauge length position; Because a clamping can be guaranteed the depth of parallelism and the symmetry of two sides, gauge length position.So not only use, easy to process, and improve the sample crudy.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a kind of structural representation of tabular stress corrosion sample.
Fig. 2 is the structural representation of an embodiment of the utility model.
Fig. 3 is the cut-open view at A-A place among Fig. 2.
Fig. 4 is the vertical view of Fig. 2.
An optimum implementation of the present utility model is: referring to Fig. 2, Fig. 3 and Fig. 4, these tabular tensile sample machine tooling anchor clamps include a clamp body 1, vertical square through hole that the tabular tensile sample 2 of planting is arranged in the middle of clamp body 1 top, and lifting movable pressing board 3 of the fluted arrangement in one side, top; The bottom surface that a pressing plate fastening bolt 8 roof pressure lifting movable pressing boards 3 are arranged on clamp body 1 central axis; Clamp body 1 crown center position shape is identical with tabular tensile sample 2 gauge length position shapes.Clamp body 1 lower side is fluted, and the bolt head of pressing plate fastening bolt 8 stretches in this groove.Lifting movable pressing board 3 lateral surfaces have gathering sill and 4 sliding joining of pressing plate feather key of vertical direction, and pressing plate feather key 4 is fixed on the clamp body 1 by two bolts 5.On the clamp body 1 bottom surface longitudinal centre line keyway is arranged, in this keyway, fix two clamp body positioning keys 7 with bolt 6.
These tabular tensile sample machine tooling anchor clamps can be used for processing tabular stress corrosion sample as shown in Figure 1.
