[background technology]
At present, the popular on the market sensor that is used for the weighing aspect, its elastic matrix forms through machining with the integral Al-alloy section bar, at its four strain faces are two the formed thin-wall regions of circular hole with certain position and certain diameter that form through machining by the aluminium alloy extrusions side, whole process all must be carried out on specialized equipment, its working (machining) efficiency is low, and rejection rate is higher; And the impact-resistant poor-performing of this elastic matrix, it is fragile, fragile to utilize this class sensor to make the product that weighing uses, and serviceable life is short.
[utility model content]
The purpose of this utility model is, is to overcome the deficiencies in the prior art, and the sensor of a kind of high precision, stable performance is provided.
In order to solve the technical matters of above-mentioned existence, the utility model adopts following technical proposals:
A kind of sensor includes sensor base, back-up block, and pressure block is characterized in that this sensor comprises that two sensor base are arranged, and they are parallel to each other and separated by a distance, and middle back-up block and the pressure block of adopting separates; Described sensor base is supported partly by the strain deformation part of disposable drawing, and stressed loading is three part compositions partly, and wherein strain deformation partly has the breach of gradual change.
Aforesaid a kind of sensor is characterized in that being that described support partly is provided with the circular hole that is used to install back-up block, also is provided with the circular hole that is used for the setting pressure piece in the stressed loading partly.
Aforesaid a kind of sensor is characterized in that being sensor base and back-up block, and pressure block links together with the method for injection moulding or die cavity die casting.
Aforesaid a kind of sensor is characterized in that being sensor base and back-up block, and pressure block links together with rivet.
Compared with prior art, the beneficial effects of the utility model are: four strain faces of elastic matrix of the present utility model utilize the disposable punching press of mould to finish, its precision height, stable performance; Utilize diel processing, be convenient to produce in enormous quantities, so the production efficiency height, rejection rate is low, and production cost is also low.

[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Sensor base 1 of the present utility model is the thin plate that adopts disposable punching press to finish, and as shown in Figure 3, it is divided into strain deformation part 2, support part 3, stressed loading is 4 three parts partly, and wherein strain deformation is partly respectively dashed gradual change breach 5,6 clocklike in 2 both sides up and down.When stressed loading part 4 loads, produce sudden change at the minimum position of breach 5 and 6, also just formed two strain deformation districts 7,8 of the present utility model.Stick respectively in strain deformation district 7,8 by " strain ga(u)ge ", the deformation in strain deformation district 7,8 makes strain ga(u)ge produce deformation thereupon, and the resistance generation linear change of the strain ga(u)ge in the circuit utilizes this principle to make the utility model then.Supporting part 3, be used to install back-up block 10 towards two circular holes 9 are arranged; Partly towards being arranged, two circular holes 11 are used for setting pressure piece 12 in 4 places in stressed loading.The breach 5,6 and the circular hole 9,11st of matrix 1 adopt disposable punching press to finish, and its production process is few, the machining precision height.Back-up block 10 and pressure block 12 can adopt injection moulding or riveted way and sensor base 1 to couple together.As Fig. 3,4,5, shown in 6, the sensor that to be the elastic matrix 1 that adopts upper and lower each parallel placement separated by a distance make through injection moulding (when using nonmetallic materials) or die cavity die casting (when using metal material) technology, so its back-up block 10, pressure block 12 are packing material (metals or nonmetal).At back-up block 10, two fixed orifices 13 are arranged respectively on the pressure block 12, be respectively applied for installing and fixing with back-up block 10 and pressure block 12.As Fig. 7,8,9, shown in 10, be with the rivet 14 of four hollows matrix 1 and back-up block 10 with two parallel placements separated by a distance, the sensor that pressure block 12 riveted joints get up to make, the fixed orifice 15,16 of rivet 14 is respectively applied for installing and fixing back-up block 10 and pressure block 12.The cross section of elastic matrix produces sudden change at the minimum position of breach 5 and 6, four sectional area saltation zones of the present utility model have also just been formed, four strain regions when pressure block 12 end loading forces, have just naturally and understandably been produced, two strain deformation districts 7 of elastic matrix 1 about being respectively, two strain deformation districts 8, stick strain ga(u)ge respectively in these four strain deformation districts, just formed the utility model." ↓ " mark 17 is that the expression power loading direction of sensor and this are held and be that power loading end, " ↓ " mark 17 are to adopt the mode of direct silk-screen, oxidation or paster to process among the figure.
Regulate the breach 5 of sensor base 1, the big or small N at 6 minimum position, distance P between the breach 5 and 6 of gradual change, the thickness t of matrix 1, and just can realize the product that the pairing weighing of sensor of different ranges is used apart from M between back-up block 10 and the pressure block 12, it highly sensitive, weighing is accurate.
The utility model in use, with its back-up block 10, pressure block 12 is installed on the product that weighing uses, by pressure block 12 upper ends 18 stressed weighing.
