Description
Technical Field
The utility model relates to a weighing system technical field especially relates to a shear beam formula weighing device.
Background
In order to ensure that a weighing sensor module is not stressed when a workpiece is installed, a top plate of the conventional shear beam type weighing device is limited by a screw fixed on a bottom plate; before the mounting is in place, the supporting nut is adjusted to ensure that a height gap of 3mm is kept between the top plate and the sensor, and the temporary supporting function is played; after the installation is finished, the supporting nuts below the top plate are loosened slowly, the top plate descends, and the weight is loaded on the weighing sensor module.
But because weight loading when the weighing sensor module, can only be by the pressure-bearing of weighing sensor module, otherwise influence the accuracy of weighing, consequently the size of screw rod will avoid with the through-hole contact of roof, this condition emergence that has just led to the decline in-process at the top can appear horizontal drunkenness, collide with, will influence the use for a long time.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a shear beam formula weighing device aims at solving current equipment unstability when transferring the roof, leads to the problem that the collision collided with the loss easily.
In order to achieve the above object, the utility model provides a following technical scheme: a shear beam type weighing device comprises a base, a shear beam type weighing sensor module, a positioning screw rod, a support nut and a top plate; the shear beam type weighing sensor module and the positioning screw rod are respectively fixed on the base, and the top plate is positioned above the shear beam type weighing sensor module and the positioning screw rod;
the positioning screw rod is composed of a lower thread part and an upper guide rod part, a support nut is installed on the lower thread part, a T-shaped support cylinder is sleeved on the upper guide rod part in a sliding contact mode and presses on the support nut, and a top plate and the T-shaped support cylinder are sleeved on the T-shaped support cylinder in a sliding contact mode and press on the T-shaped support cylinder.
Preferably, the front end of the shear beam type weighing sensor module is provided with a steel ball module for supporting.
Preferably, the upper ends of the positioning screw and the T-shaped supporting cylinder are lower than the upper surface of the top plate.
Preferably, stepped grooves are formed in the positions, located on the positioning screw and the T-shaped supporting barrel, of the top plate.
The utility model has the advantages that: the roof of below is stable, and when weighing, can not influence weighing module and independently bear.

Detailed Description
As shown in fig. 1, 2 and 3, a shear beam type weighing device comprises a base 1, a shear beam type weighing sensor module 2, a positioning screw, a support nut 4 and a top plate 6; the shear beam type weighing sensor module 2 and the positioning screw rod are respectively fixed on the base 1, and the top plate 6 is positioned above the shear beam type weighing sensor module 2 and the positioning screw rod;
the positioning screw is composed of a lower thread part 31 and an upper guide rod part 32, a support nut 4 is installed on the lower thread part 31, the upper guide rod part 32 is sleeved with a T-shaped support cylinder 5 in a sliding contact mode, the T-shaped support cylinder 5 is pressed on the support nut 4, and a top plate 6 is sleeved with the T-shaped support cylinder 5 in a sliding contact mode and pressed on the T-shaped support cylinder 5.
The utility model discloses a support nut 4 still is used for interim support to increased T type support cylinder 5 and be used for direct support and with the contact of the through-hole inner wall of roof 6, the positioning screw divide into lower screw thread portion 31 and upper guide arm portion 32 simultaneously, 5 holes of T type support cylinder contact with upper guide arm portion 32 again, consequently, when rotating support nut 4 and descend, roof 6 and T type support cylinder 5 can be stable slide down along upper guide arm portion 32 (the contact surface selects smooth material or can suitably supply some emollient), can not have horizontal drunkenness, collide with;
after the top plate 6 is lowered to the position where the shear beam type weighing sensor module 2 is pressed, the support nut 4 needs to be continuously rotated to descend, so that the T-shaped support cylinder 5 is separated from the through hole of the top plate 6, the top plate 6 is only contacted with the shear beam type weighing sensor module 2, and the weighing accuracy of the shear beam type weighing sensor module is guaranteed.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
