A kind of pillar LOAD CELLS; Comprise pressure head, response body, be fixedly installed on the base of response body bottom, the data line that is arranged on the foil gauge on the response body and is connected with foil gauge; Response body top is the stepped right cylinder that shaft section is the T font, and stepped cylindrical end face is a sphere; Said pressure head end face is provided with stepped through hole, and stepped through hole from top to bottom sectional area reduce gradually; Be positioned at stepped through hole top on the pressure head end face and be provided with pressing plate, the stepped right cylinder on said response body top is located in the stepped through hole of pressure head, and is provided with the gap between stepped right cylinder and the stepped through hole, and stepped right cylinder end face supports and the pressing plate bottom surface.Owing to be provided with the gap between the stepped through hole of the stepped right cylinder on response body top and pressure head, and stepped right cylinder to get end face be sphere with pressing plate between contact for putting, so pressure head can be with respect to response body at the certain angle intrinsic deflection.Simultaneously owing to contact for point between the stepped right cylinder on response body top and the pressing plate; Object departs from the acting force of response body and the center line of response body even weighed; When response body is produced side force, torsion; The stepped right cylinder on response body top keeps still reliably with pressing plate on the pressure head that some contact, can not influence the stressed of response body top, and therefore the measuring accuracy to LOAD CELLS influences smaller.
As preferably, the base bottom is provided with lower connecting base, and the lower connecting base bottom surface is the dip plane.The base bottom of the LOAD CELLS of this programme also is provided with lower connecting base, can improve the bearing resistance of LOAD CELLS.The lower connecting base bottom surface is the dip plane simultaneously, can match with the dip plane of the object of being weighed when mounted, is applicable on the dip plane that is installed in the object of being weighed.
As preferably, it is cylindric that response body is, and the side of response body is provided with the perpendicular that is extended to the bottom by the response body top; The perpendicular middle part is provided with circular hole; Said circular hole bottom surface is provided with strain bore, and described foil gauge is attached on the strain bore bottom surface, is provided with end cover in the said circular hole.End cover is arranged in the circular hole foil gauge in the strain bore is sealed in response body inside.
As preferably, the quantity of strain bore is four, and strain bore is that two rows distribute and each strain bore is distributed on the same circumference.The layout of a plurality of strain bores can increase the quantity of foil gauge, and the distributing position of each foil gauge can improve the accuracy of detection of LOAD CELLS simultaneously.
As preferably, response body is provided with water joint, and said data line passes water joint and is connected with foil gauge; Be tightly connected between said water joint and the response body, be tightly connected between water joint and the lead.Water joint can play sealing function, improves the serviceable life of LOAD CELLS.
As preferably, the stepped through hole of pressure head end face is provided with two stage rank, and said pressing plate is positioned on the first stage rank, and the pressing plate end face flushes with the pressure head end face; Said pressure head top also is provided with upper connecting base.The upper connecting base that the pressure head top is provided with can improve the bearing resistance of LOAD CELLS.
The beneficial effect of the utility model is: the side force of the object that receives to be weighed and torsion influence little, measuring accuracy is high, bearing resistance good.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Among the figure: response body 1, upper connecting base 2, lower connecting base 3, pressure head 4, base 5, perpendicular 6, strain bore 7, end cover 8, water joint, data line 10, pressing plate 11, stepped right cylinder 12.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1, a kind of pillar LOAD CELLS comprises pressure head 4, response body 1, is fixedly installed on the base 5 of response body bottom, the data line 10 that is arranged on the foil gauge on the response body and is connected with foil gauge.Response body 1 top is the stepped right cylinder 12 that shaft section is the T font, and the cylindrical end face of scalariform is a sphere.Said pressure head 4 end faces are provided with stepped through hole, and stepped through hole is provided with two stage rank, and stepped through hole from top to bottom sectional area reduce gradually.The first stage rank of the stepped through hole of pressure head 4 are provided with pressing plate 11, and the bottom surface of pressing plate and end face are the plane, and pressing plate 11 end faces flush with pressure head 4 end faces; Pressing plate 11 is through being bolted on the pressure head.The stepped right cylinder 12 on said response body 1 top is located in the stepped through hole of pressure head 4, and is provided with the gap between stepped right cylinder 12 and the stepped through hole.Stepped right cylinder 12 end faces support and pressing plate 11 bottom surfaces.Response body 1 is cylindric; The side of response body is provided with the perpendicular 6 that is extended to the bottom by the response body top; The perpendicular middle part is provided with circular hole; Said circular hole bottom surface is provided with strain bore 7, and the quantity of strain bore is four, and strain bore is, and two rows distribute and each strain bore is distributed on the same circumference.Post foil gauge on said each strain bore 7 bottom surface, be provided with end cover 8 in the said circular hole.Response body 1 is provided with water joint 9, and said data line 10 passes water joint 9 and is connected with foil gauge; Be tightly connected between said water joint and the response body, be tightly connected between water joint and the lead.Said pressure head 4 tops also are provided with upper connecting base 2, and upper connecting base is connected through bolt with pressure head.Base 5 bottoms are provided with lower connecting base 3, and the lower connecting base bottom surface is the dip plane.Lower connecting base is connected through bolt with base.
