Abstract
The utility model relates to the field of electronic truck scales, especially to a bridge-type sensor self-positioning device. The device mainly comprises a scale body, a bridge-type sensor, a lower positioning bowl, a foundation plate, an upper positioning bowl, a bearing ball and a base plate. When the sensor is placed invertedly, the base plate and the foundation plate under the lower positioning bowl are in free states.; and with a self-centering feature of the bearing ball adopted, the stressed direction of the sensor when the scale body is used is always perpendicular to the ground, and a load is totally transferred to the sensor, thereby ensuring weighing accuracy and reducing errors.
Description
Technical field
The utility model relates to the electronic vehicle weighing apparatus field, especially a kind of bridge type magnetic sensor self locating device.
Background technology
At present; The installation method of bridge type magnetic sensor is that sensor is fixed on the foundation plate with foot bolt; Make sensor be able to fix, can prevent the displacement of scale body, but because foot bolt is to be cast in the concrete on basis; Be difficult to guarantee its position, therefore also just guaranteed not sensor the force direction that receives be in vertical direction.
Summary of the invention
In order to overcome the deficiency of existing sensor location technology; The utility model provides a kind of bridge type magnetic sensor self locating device; The scale body in use force direction that receives of sensor is perpendicular to the ground, and load all passes to sensor, has guaranteed weighing precision and has reduced error.
The utility model solves the technical scheme that its technical matters adopted: the bridge type magnetic sensor self locating device, and mainly comprise scale body, bridge type magnetic sensor, following location bowl, foundation plate, go up location bowl, bearing ball and backing plate, bridge type magnetic sensor is inverted; Be installed on the scale body, last location bowl downwards, between bearing ball is installed in the location bowl and locatees down bowl; Bearing ball is a spheroidal, and following location bowl upwards makes down location following backing plate and the foundation plate of bowl be free state; Adopt the self-centering characteristics of ball; Making the scale body in use receive force direction is vertical direction all the time, even rock, it is perpendicular to the ground also making the force direction that receives of sensor; Load all passes to sensor, has guaranteed weighing precision and has reduced error.
The beneficial effect of the utility model is; The bridge type magnetic sensor self locating device is inverted sensor, and following backing plate and the foundation plate of following location bowl is free state; Adopt the self-centering characteristics of ball; Make the scale body in use the force direction that receives of sensor be perpendicular to the ground all the time, load all passes to sensor, has guaranteed weighing precision and has reduced error.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing is the utility model synoptic diagram.
1. scale bodies among the figure, 2. bridge type magnetic sensor, 3. time location bowl, 4. foundation plate, 5. on location bowl, 6. bearing ball, 7. backing plate.
Embodiment
In the accompanying drawing, bridge type magnetic sensor (2) is installed on the scale body (1), is inverted bridge type magnetic sensor (2); Last location bowl (5) is downward, and bearing ball (6) is between last location bowl (5) and following location bowl (3), and following location bowl (3) upwards; Make down the following backing plate (7) of location bowl (3) be free state with foundation plate (4), adopt the self-centering characteristics of ball, making scale body (1) in use receive force direction is vertical direction all the time; Even rock; Also can make the force direction that receives of bridge type magnetic sensor (2) is perpendicular to the ground all the time, and load all passes to sensor, has guaranteed weighing precision and has reduced error.
Claims (3)
1. bridge type magnetic sensor self locating device; Mainly comprise scale body, bridge type magnetic sensor, following location bowl, foundation plate, go up location bowl, bearing ball and backing plate, it is characterized in that: the bridge type magnetic sensor inversion is installed on the scale body; Last location bowl downwards; Bearing ball is installed in location bowl with down between the bowl of location, and following location bowl upwards makes down and locatees bowl following a backing plate and a foundation plate and be free state.
2. bridge type magnetic sensor self locating device according to claim 1 is characterized in that: adopt the self-centering characteristics of ball, making the scale body in use receive force direction is vertical direction all the time.
