Abstract
The utility model relates to a forklift scale sensor device, and the device comprises a sensor and a sensor pressure head, wherein pressure head holes are formed close to the end part of the sensor; the sensor pressure head is arranged above the pressure head holes; a boss with a hole is arranged at the lower end of the sensor pressure head; the lower end of the boss is tightly clung to the upper ends of the pressure head holes; a fastening bolt is arranged in the pressure head holes and a screw mounting hole to connect and fasten the sensor pressure head and the sensor; the fastening bolt is a hexagonal bolt; the pressure head holes are two step type straight-through holes; a screw rod of the hexagonal bolt is arranged in the upper step hole; and the hexagon of the bolt is arranged in the lower step hole, so that the fastening bolt is clamped with the pressure head holes. According to the forklift scale sensor device, a thrust surface of the sensor is changed from the original upper step hole to the upper end surface of each pressure head hole so as to greatly reduce lateral buckling force of the sensor, so that the mostly force is vertical downward gravity, the measurement error is lower in comparison with the original value, and no screw threads are machined in the screw mounting hole, and thus the labor, material resources and the machining cost are saved.
Description
Technical field
The utility model relates to the Balancer for fork trucks field, is specifically related to a kind of Balancer for fork trucks sensor device.
Background technology
Balancer for fork trucks weighing principle is that some pressure load cells are fixed on respectively in the hand hydraulic carrier fork leg, hold top weighing platen by the sensor pressure head, object places the platen upper sensor can induce weight and spreads out of electric signal calculates actual object to display weight.
The Balancer for fork trucks sensor of at present routine use, as shown in Figure 1, comprise sensor 1 and sensor pressure head 3, have the screw mounting hole in the sensor pressure head 3, sensor 1 has the pressure head hole near in the position of end, the pressure head hole is two stepped holes, the upper step hole is larger, the bottom of built-in sensors pressure head 3, and the lower step hole is less, built-in screw 11 is fixed chucking by screw 11 with sensor pressure head 3 and sensor 1.Sensor pressure head 3 tops are fixedly connected with the platen 2 of weighing by pressure head backing plate 4.
This kind structure check weighing face is the pressure head bottom, sensor pressure head 3 places the part in the pressure head hole will cast aside the pressure head hole after the car leg is subjected to heavily flexural deformation, thereby produced the slash Qu Li of side direction, on original vertical stressed basis, increased again like this slash Qu Li of side direction, along with gravity strengthens, side direction is cast aside Qu Li also to be increased thereupon, and machining gap also can cause side direction to cast aside the change of Qu Li between pressure head hole and the sensor pressure head 3, and each set to power will cause the weighing error to strengthen.
The utility model content
Be to solve the problem that prior art exists, the utility model provides a kind of bent power less, Balancer for fork trucks sensor device that weighting error is less cast aside.
Balancer for fork trucks sensor device described in the utility model, comprise sensor and sensor pressure head, has the screw mounting hole in the described sensor pressure head, described sensor has the pressure head hole near the position of end, described sensor pressure head places top, described pressure head hole, sensor pressure head lower end has boss with holes, and upper end, described pressure head hole is close in described boss lower end, and a fastening bolt places described pressure head hole and interior described sensor pressure head is connected with sensor of screw mounting hole to tighten up.
Further, described fastening bolt is hex bolts, and described pressure head hole is two step clear openings, and the screw rod of hex bolts places in the upper step hole, and the bolt hexagonal places in the lower step hole, thereby fastening bolt engages with the pressure head hole.
Balancer for fork trucks sensor device described in the utility model, its beneficial effect is:
The sensor pressure head is placed top, pressure head hole, pressure head is not arranged in the pressure head hole, be installed in by a hex bolts in the screw of pressure head hole sensor pressure head, sensor is connected with the sensor pressure head tightens up, thereby the sensor stress surface has changed to the upper surface in pressure head hole from original upper step hole, the side direction that can greatly reduce like this sensor is cast aside Qu Li, thereby more is gravity vertically downward, and measuring error is compared little a lot.

Embodiment
The below will describe the utility model in detail with specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Embodiment:
As shown in Figure 2, Balancer for fork trucks sensor device described in the utility model, comprise sensor 1 and sensor pressure head 3, as shown in Figure 4, have screw mounting hole 8 in the sensor pressure head 3, sensor 1 has the pressure head hole near in the position of end, and sensor pressure head 3 has boss with holes 7 near an end of sensor, the laterally inclined miter angle of boss 7 forms a cone boss, and upper end, pressure head hole is close in boss 7 lower ends.One hex bolts places in the screw mounting hole 8 of described pressure head hole and pressure head.
The pressure head hole is two step clear openings, as shown in Figure 3, the pressure head hole comprises upper step hole 6 and lower step hole 5, upper step hole 6 diameters are less, lower step hole 5 diameters are larger, and the screw rod 9 of hex bolts places in the upper step hole 6, and bolt hexagonal 10 places in the lower step hole 5, thereby hex bolts engages with the pressure head hole, sensor pressure head 3 is connected with sensor 1 tighten up.Sensor pressure head 3 tops are fixedly connected with the platen 2 of weighing by pressure head backing plate 4.When weighing, the sensor stress surface has changed to the upper surface in pressure head hole from original upper step hole, and the side direction that can greatly reduce like this sensor is cast aside Qu Li, thereby more is gravity vertically downward, and measuring error is compared little a lot.
More than technical scheme that the utility model embodiment is provided be described in detail, this paper has used specific case principle and the embodiment of the utility model embodiment has been set forth, and the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
