Abstract
The utility model relates to a weighing machine structure of a spoke sensor, which comprises a spoke sensor body (3). The weighing machine structure is characterized in that the end surface of an adjusting pole (2) contacting a supporting pressure head (1) is a curved surface, and the adjusting pole (2) or a steel ball (4) or a rocking pole (7) contacts the supporting pressure head (1) and an adjusting pressure head (5) by the curved face. Impact force can be buffered and counteracted by means of relative rolling or slide of the curved surface and the supporting pressure head (1) if an accidental side impact occurs, and automatic replacement can be achieved, so that effective performance of the sensor can be ensured.
Description
Technical field
The utility model relates to a kind of weighing apparatus sensor technology, a kind of specifically weighing apparatus structure of spoke sensor.
Background technology
At present, domestic weighing apparatus type of sensor is taked cantilever beam sensor, bridge type magnetic sensor or column type sensor mostly.Cantilever beam sensor, bridge type magnetic sensor are analyzed from version, its anti-bias load, shock resistance characteristic a little less than, frequency response is lower, the stressed back of carrying scale body deflection is big, self is difficult on the structure realize that sensor is from spacing.Column type sensor shock resistance characteristic, frequency response, scale body deflection aspect, the stressed back of carrying performance are better than cantilever beam sensor and bridge type magnetic sensor, but its maximum defective is to have relatively poor non-linear, particularly homemade column type sensor, because be subjected to existing compensate for process, film-making technogenic influence, precision is starkly lower than the other types sensor.
The spoke sensor is with its distinctive borehole structure that waits, determined performance to be better than the other types sensor, had that high precision, high reliability, anti-bias load that the circumferential position variable effect is little, strong, strong shock resistance, the stressed back of carrying scale body deflection are little, be easy to realize that sensor is from advantage such as spacing on the structure.
But, the spoke sensor can not get widespread use aspect weighing apparatus for a long time, and its fundamental cause is not have rational type of attachment and buffering runback bit architecture, causes spoke sensor shock resistance characteristic to descend, even cause the sensor failure sex change, influenced the normal use of spoke sensor.
Summary of the invention
The utility model is exactly for solving the deficiency that the decline of spoke sensor shock resistance characteristic causes the sensor failure sex change, a kind of weighing apparatus structure that has stronger shock resistance characteristic, can guarantee the spoke sensor of sensor performance being provided.
The technical solution that realizes above-mentioned purpose is: with the end face that supports the contacted adjustable column of pressure head be a curved surface.
The utility model is at the defective of spoke sensor existence in weighing apparatus uses and custom-designed a kind of new structure, it has improved traditional connected mode of spoke sensor, mainly be to utilize the curved surface of adjustable column termination and contacting of support pressure head, have buffering and from reset function, effectively avoided the performance failure that sensor causes because of rigid impact even the phenomenon of connecting portion fracture.Kept simultaneously that spoke sensor high precision, high reliability, circumferential position variable effect are little, anti-bias load and strong shock resistance, the stressed back of carrying scale body sink and be easy to realize that sensor is from spacing characteristic on little, the structure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an another example structure synoptic diagram of the present utility model.
Fig. 3 is another example structure synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1, respectively by the adjustable column 2 that has been threaded, each adjustable column 2 is a curved surface (or bulb) with the contact position of supporting pressure head 1 in the both sides up and down of spoke sensor 3, and the surface of contact that supports pressure head 1 and adjustable column 2 is a plane.
Fig. 2 is an another example structure synoptic diagram of the present utility model.One side of regulating pressure head 5 and spoke sensor 3 is by being threaded, and regulates pressure head 5 and a steel ball 4 being set with supporting between the pressure head 1, and the sphere of this steel ball 4 contacts with the concave surface of adjusting pressure head 5 with support pressure head 1.The opposite side of spoke sensor 3 by be threaded one with the fixing lower connecting plate 6 of frame.
Fig. 3 is another example structure synoptic diagram of the present utility model.One side of regulating pressure head 5 and spoke sensor 3 is by being threaded, and regulate pressure head 5 with support be provided with between the pressure head 1 two ends be curved surface (or bulb) shake post 7, the curved surface that shakes post 7 two ends respectively with regulate the inner plane of pressure head 5 and contact with support pressure head 1.At the opposite side of spoke sensor 3, also by the lower connecting plate 6 of fixing with frame that is threaded.
Above-mentioned several structure mainly is adjustable column 2 or steel ball 4 to be described or to have shaken post 7 to contact with support pressure head 1 and adjusting pressure head 5 by curved surface, as run into unexpected lateral impact, can cushion and offset impulsive force with relative rolling or the slip of supporting pressure head 1 by curved surface, and can realize automatically reseting, thereby can guarantee the effective performance of sensor.
Three kinds of embodiments of the present utility model have below just been listed; but its structure is not limited in this three kinds of forms, if spoke sensor 3 have a N-Side surf with support pressure head 1 or with support the contacted version of parts that pressure head 1 has identical functions and all should list protection domain of the present utility model in.
Claims (1)
1. the weighing apparatus structure of a spoke sensor comprises spoke sensor (3) itself, it is characterized in that with the end face that supports the contacted adjustable column of pressure head (1) (2) be a curved surface.
