The present invention relates to detection technique field, especially a kind of method of simple and efficient discriminating off-the-road tyre hardness and device.
Background technology
Usual off-the-road tyre all will carry out hardness test after making finished product on a production line, to tell the underproof product of hardness, because in suitability for industrialized production, output is very large, if whether directly can differentiate its hardness quickly to product on a production line with a kind of simple and practical device qualified, there are significant use value and economic benefit by the qualification rate and production efficiency that improve product.
Summary of the invention
The object of the invention is: method and device that a kind of simple and efficient discriminating off-the-road tyre hardness is provided, its structure be simple, easy and simple to handle, rapidly and efficiently, good reliability.
The present invention is achieved in that the method for simple and efficient discriminating off-the-road tyre hardness, the standard pressure weight of a constant weight is set, weight standard is pressed to be placed in the qualified off-the-road tyre standard model surface of hardness, standard is utilized to press the deadweight of weight to extrude off-the-road tyre standard model, obtain an extruding degree of depth, be designated as standard depth, recycle same method, weight standard is pressed to detect off-the-road tyre to be measured, obtain and detect the degree of depth, the detection degree of depth and standard depth are contrasted, if detect the degree of depth to be greater than standard depth, then differentiate that this off-the-road tyre hardness to be measured is defective, if detect the degree of depth to be less than or equal to standard depth, then differentiate that this off-the-road tyre hardness to be measured is qualified.
The device of simple and efficient discriminating off-the-road tyre hardness, comprise detection cylindrical shell, detect the open at both ends of cylindrical shell, be cylindrical cavity in the middle part of it, columniform standard pressure weight is provided with in the cavity detecting cylindrical shell, be provided with certification mark bar at the top of standard pressure weight, certification mark bar is provided with home block.
The bottom of described standard pressure weight is inverted cone-shaped structure, and its bottom is arc surface.Such structure can increase standard pressure weight to the pressure of surface of tyre, but can not damage tire again, is conducive to the overall weight of alleviator.
Be provided with the cylindrical shell positive stop lug boss of annular at the top of described detection cylindrical shell, the internal diameter of cylindrical shell positive stop lug boss is greater than the external diameter of certification mark bar, but is less than the external diameter of standard pressure weight; Be provided with circular marking rod positive stop lug boss on the top of certification mark bar, the external diameter of marking rod positive stop lug boss is greater than the internal diameter of cylindrical shell positive stop lug boss.Such structure can ensure that standard pressure weight can not depart from detection cylindrical shell, is convenient for carrying, also avoids loss of parts.
Owing to have employed technique scheme, compared with prior art, the present invention adopts standard to press weight examination criteria sample, to obtain standard depth, when detecting product to be measured more fast, only need the degree of depth measured and standard depth to contrast, can judge that whether product is qualified.And standard pressed weight to be arranged on the structure detected in cylindrical shell, can ensure that standard pressure weight can vertically press down, ensure that the accuracy of test, and be provided with certification mark bar, testing result can be learnt fast and accurately, greatly simplify operating process, to be very applicable to on-the-spot to use online, and the accuracy detected is good.Method of the present invention is simple, and the apparatus structure adopted is simple, and cost of manufacture is low, and result of use is good.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is use schematic diagram of the present invention.
Embodiment
Embodiments of the invention: the method for simple and efficient discriminating off-the-road tyre hardness, the standard pressure weight of a constant weight is set, weight standard is pressed to be placed in the qualified off-the-road tyre standard model surface of hardness, standard is utilized to press the deadweight of weight to extrude off-the-road tyre standard model, obtain an extruding degree of depth, be designated as standard depth, recycle same method, weight standard is pressed to detect off-the-road tyre to be measured, obtain and detect the degree of depth, the detection degree of depth and standard depth are contrasted, if detect the degree of depth to be greater than standard depth, then differentiate that this off-the-road tyre hardness to be measured is defective, if detect the degree of depth to be less than or equal to standard depth, then differentiate that this off-the-road tyre hardness to be measured is qualified.
The device of simple and efficient discriminating off-the-road tyre hardness, comprise and detect cylindrical shell 1, detect the open at both ends of cylindrical shell 1, be cylindrical cavity in the middle part of it, columniform standard pressure weight 2 is provided with in the cavity detecting cylindrical shell 1, be provided with certification mark bar 3 at the top of standard pressure weight 2, certification mark bar 3 is provided with home block 4; The bottom of described standard pressure weight 2 is inverted cone-shaped structure, and its bottom is arc surface; Be provided with the cylindrical shell positive stop lug boss 5 of annular at the top of described detection cylindrical shell 1, the internal diameter of cylindrical shell positive stop lug boss 5 is greater than the external diameter of certification mark bar 3, but is less than the external diameter of standard pressure weight 2; Be provided with circular marking rod positive stop lug boss 6 on the top of certification mark bar 3, the external diameter of marking rod positive stop lug boss 6 is greater than the internal diameter of cylindrical shell positive stop lug boss 5.
In use, first detect the qualified off-the-road tyre standard model of hardness, standard model is pressed into and under stable condition at standard pressure weight 2, home block 4 is navigated on certification mark bar 3, allow user can observe home block 4 from horizontal level, the home block 4 observed highly is about in 1mm(the present embodiment, home block 4 can adopt the coloured paster of band, can observe clearly as long as its size meets user), after determining the position of home block 4, said method is adopted to detect product to be measured in the device of the present embodiment, after detecting step completes, as long as user can observe home block 4 at horizontal level and namely illustrate that the hardness of product to be measured is satisfactory, if and home block 4 can not be seen on horizontal level, then illustrate that the hardness of product is defective.
