Background technique
Chopper is a kind of people's commonly kitchen utensils.However, chopper quality is irregular, ordinary consumer is difficult to know
The quality of chopper quality.
The subjective evaluation and test stage that hand is touched is seen by eye by people currently, also resting on for the inspection of chopper quality, lacks one
A standard for objectively evaluating chopper quality.And chopper quality, by the tough and tensile of the highest blade of frequency of use on chopper
Property determine, the chopper of toughness difference is easy to appear " turned " after use (that is: to be there is the situation bent slightly, uses on blade
Hand is touched from sword side can slightly hang hand) or " chipping " (that is: small gap occurs in blade local fracture).
Based on this, applicant considers to design a kind of structurally reasonable, can help the chopper toughness for differentiating chopper toughness
Detection device.
Summary of the invention
In view of the above shortcomings of the prior art, the technical problem to be solved by the utility model is to how to provide a kind of knot
Structure is reasonable, can help the chopper toughness detection device for differentiating chopper toughness.
In order to solve the above-mentioned technical problem, the utility model uses the following technical solution:
A kind of chopper toughness detection device, including pedestal, anvil block, bracket, impact cutting driving mechanism, chopper clamping device and
Camera；
Anvil block lower end is fixedly mounted on the upper surface of the pedestal；The upper surface of the anvil block is equipped with the mark of strip
Sample, which is placed, uses groove, and the standard specimen placement is used to put off for the standard specimen of strip in wherein with groove；The upper surface of the anvil block
It is additionally provided with blade incision groove, the blade incision is pitched with the standard specimen placement with grooves with groove, and the knife

51 lower face is fixedly connected at least two fastening clamps 52 along its length；Each fastening clamp 52 is whole in opening down
N structure, it is each fastening 52 n structure of clamp one of them vertical block on through be equipped with threaded hole, the spiral shell
A locking bolt 53 is screwed in pit.
The above-mentioned chopper clamping device of #, by multiple fastening clamps 52 come the knife spine of clamping chopper, so that chopper blade court
Under；At the same time, the advantages of each fastening clamp 52 is in n structure is: not only can be by the transverse direction at the top of n structure
Block with fixed mounting plate 51 come for being fixedly linked, additionally it is possible to be offseted using the lateral blocks at the top of n structure with knife spine
It connects, carries out impact cutting so as to apply bigger vertical force to chopper.
Wherein, the standard specimen is the graphite pencil 7 of all kinds of hardness leveles.
# graphite pencil 7 is pencil-lead using graphite as the pencil of primary raw material, and pencil-lead is enclosed with timber.
The hardness mark of graphite lead core is printed on existing graphite pencil 7, it is general to indicate hard pencil, " B " table with " H "
Show soft pencil, " HB " indicates that neither too hard, nor too soft pencil, " F " indicate pencil of the hardness between HB and H.In addition, graphite pencil 7
18 hardness leveles such as 6B, 5B, 4B, 3B, 2B, B, HB, F, H, 2H, 3H, 4H, 5H, 6H, 7H, 8H, 9H, 10H are divided into, before alphabetical
The number in face is bigger, shows respectively harder or softer.
# this programme selects the graphite pencil 7 of various hardness as standard specimen, not only has the advantages that buying is convenient, moreover it is possible to
Enough so that the consistency of the standard specimen of various hardness leveles is more preferable, so that chopper toughness testing result is more objective and accurate and closes
Reason.
Wherein, the camera 6 is industrial camera.
For # for traditional civil camera (video camera), industrial camera has high picture steadiness, high-transmission energy
Power and high anti-jamming capacity etc..The aperture time of industrial camera is very short, can capture swiftly passing object, obtains higher
Image quality more can accurately reflect chopper toughness testing result.
Wherein, chopper toughness detection device further includes standard specimen thrust gear, and the standard specimen thrust gear is fixedly mounted on
On the pedestal 1, and the standard specimen thrust gear has a telescopic push rod 81, the outer end of the push rod 81 it is neighbouring and with it is described
Standard specimen placement is faced with one end of groove 21.
After # uses above-mentioned standard specimen thrust gear, after may make single standard specimen part to be cut, by push rod 81 come ejection
Standard specimen, and the part that do not cut on single standard specimen is made to be located at blade incision groove 22 and the standard specimen placement ditch again
Detection is saved this makes it possible to more make full use of single standard specimen to obtain more testing results in the position that slot 21 intersects
While cost, it is also able to ascend the safety of detection operation.
When # is implemented, be preferably vertically fixedly installed with one piece of ejector plate 82 in the outer end of push rod 81, the ejector plate 82 it is upper
The height slightly above described standard specimen in end is placed with 1-3 millimeters of lowest position in groove 21.So, ejector plate 82 can be passed through
Carry out accurate ejection standard specimen, and can be avoided ejector plate 82 and 6 shot location of camera is blocked.
Wherein, the push rod 81 is electric pushrod 81.
# electric pushrod 81 has easy to use, the high advantage of mobile accuracy.
Wherein, chopper toughness detection device further includes anvil block micro-adjusting mechanism, and the anvil block micro-adjusting mechanism includes fixed plate

The fixed plate 91 is fixedly mounted on the upper surface of the pedestal 1, and the fixed plate 91 is to put in the standard specimen
Two pieces be arranged with the length direction parallel interval of groove 21 are set, are vertically and fixedly provided with 92 He of guide rail between two fixed plates 91
Lead screw 93 is socketed with the nut 95 on the lead screw 93, and the lower surface of the supporting station 96 is fixedly linked with the nut 95,
And the lower surface of the supporting station 96 is also fixedly installed with the sliding block 94 being slidably socketed on the guide rail 92；The supporting station 96
Upper surface be fixedly installed with the anvil block 2；
One end of the lead screw 93 is through the fixed plate 91 and is fixedly installed with the regulation handle 97.
# because various chopper cutting edges thickness it is inconsistent, and by the inconsistent chopper of various thickness it is clamping chopper clamp
After mechanism, the position of the projection on various chopper blades in the same plane vertical is different.
So using above-mentioned anvil block micro-adjusting mechanism, can by rotation regulation handle 97 come so that supporting station 96 in standard specimen
Micro-shifting on the length direction with groove 21 is placed, so that various chopper blades being capable of face blade incision groove 22.
At the same time, also there is the structure that lead screw 93 and nut 95 cooperate self-locking function (not operate regulation handle 97, spiral shell
Mother 95 will not move), improve the stability that supporting station 96 positions, it is ensured that the reliability of detection.
As it can be seen that the use of above-mentioned anvil block micro-adjusting mechanism, effectively improves the practicability of anvil block 2；At the same time, above-mentioned anvil block
The use of micro-adjusting mechanism can also further shorten the width of blade incision groove 22, to promote 21 slot of standard specimen placement groove
The reliability that bottom supports standard specimen avoids standard specimen in cutting process from being moved down the situation that the impact force of chopper is thrust.
The above is only the utility model preferred embodiments, it is noted that not taking off for those skilled in the art
Under the premise of from the technical program, the technical solution for the several modifications and improvements made should equally be contemplated as falling within the claims
Claimed range.
