It is square into thus, it is ensured that the accuracy of test is it is necessary to ensuring with the maximum position of the most weakness or stress of material property
Sample cutting and preparing, and shape, the size to sample carry out effective measurement analysis.For cube, cylinder, its chi
It is very little can be with various slide calliper rule come direct measurement, for some breach, existing slide calliper rule can also direct measurement.However, due to each
Planting the card base of slide calliper rule has one fixed width, therefore, when the width of some breach (such as v-notch) is extremely tiny, slide calliper rule
Card base can not be deep into indentations bottom, so that true value can not be measured.
In the prior art, directly tested using measurement table, it is difficult to ensure the accuracy of measurement.It is difficult in adapt to not simultaneously
With the test of high measure sample, and it is unfavorable for picking and placeing test sample.In view of notch depth has important for measurement result
Influence, it is necessary to further improve measurement accuracy
The content of the invention
The utility model provides a kind of notch detection device, the test sample of different height is adapted to, while to sample
Firmly clamped, further increase measuring accuracy.
In order to solve the above-mentioned technical problem, technical solution adopted in the utility model is：
A kind of notch detection device, including base, the both sides of the base, which are provided with column, the column, is provided with horizontal stroke
The fixed seat being provided with immediately below measurement table, the measurement table for fixed standard part is provided with beam, the crossbeam, it is described
The both sides of fixed seat symmetrically offer the opening for placing test specimens, and the bottom of the opening is opened to the bottom of the fixed seat
Portion.
Further, the measurement table includes table body, measurement bar, measurement head and fork, and the fork is arranged on the table
On body, for adjusting the flexible of measurement bar, the measurement bar drive connection measurement head.
Further, it is provided with slide rail on each column, the crossbeam is slidably connected the slide rail, the crossbeam
It is fixed on by knob on the slide rail.The height of measurement table is adjusted according to different testing standard parts, it is ensured that zeroing is accurate.
Yet further, the clamping device for clamping test sample is provided with the base, the clamping device includes
Grip block, fixed plate and the spring array being arranged between the grip block and fixed plate；The clamping device is symmetrical arranged
In the both sides of the fixed seat.Easily test product can be picked and placeed and fixed using clamping device.
Preferably, the scale of home position is provided with the grip block；Position is accurate when ensuring to clamp.
Preferably, it is provided with level meter on front side of the base；When ensuring test, the levelness of whole instrument.
Preferably, four angles of the bottom of the base are provided with the adjustment screw for adjusting height；For adjusting bottom
The level height of seat.
The utility model provides a kind of notch detection device, including base, and the both sides of the base are provided with column, described
It is provided with column on crossbeam, the crossbeam and is provided with measurement table, is provided with immediately below the measurement table for fixed standard
The fixed seat of part, the both sides of the fixed seat symmetrically offer the opening for placing test specimens, and the bottom of the opening is opened
To the bottom of the fixed seat.The measurement table includes table body, measurement bar, measurement head and fork, and the fork is arranged on described
On table body, for adjusting the flexible of measurement bar, the measurement bar drive connection measurement head.It is provided with each column
Slide rail, the crossbeam is slidably connected the slide rail, and the crossbeam is fixed on the slide rail by knob.The detection means can be with
The test of different height material breach is adapted to, while firmly being clamped to sample, measuring accuracy is further increased.
Brief description of the drawings
Fig. 1 is a kind of notch detection apparatus structure schematic diagram of the utility model.
Embodiment
Below in conjunction with the accompanying drawings, embodiment of the present utility model is specifically illustrated, accompanying drawing is only for reference and explanation is used, not structure
The limitation of paired the utility model scope of patent protection.
As shown in figure 1, a kind of notch detection device, including base 1, the both sides of the base 1 are provided with column 2, described
It is provided with column 2 on crossbeam 3, the crossbeam 3 and is provided with measurement table 4, the underface of the measurement table 4 is provided with for fixing
The fixed seat 7 of standard component, the both sides of the fixed seat 7 symmetrically offer the opening 71 for placing test specimens, the opening
Open to the bottom of the fixed seat 7 71 bottom.4 tables of the measurement include table body, measurement bar 42, measurement head 43 and fork 41,
The fork 41 is arranged on the table body, for adjusting the flexible of measurement bar 42, and the measurement bar 42 is connected described survey
Amount first 43.
It is provided with slide rail 5 on each column 2, the crossbeam 3 is slidably connected the slide rail 5, the crossbeam 3 passes through rotation
