Description
Technical field
The present invention relates to a kind of LOAD CELLS, especially relate to a kind of buffer-type Weighing cell module.
Background technology
At present also there is not perfect buffer structure form in LOAD CELLS and weighing system field, domestic and international application was ripe in the past is exactly that scale body portion at weighing system adopts split type buffer structure, the two weighing platform structures of utilization reach the buffering to the wide range material, its core is to utilize the space between upper strata weighing platform and the lower floor's weighing platform to add buffer spring, the maximum drawback of this structure is the scale structure complexity, this body weight is overweight, steel using amount increases greatly, especially the application of special occasions and inconvenience thereof, this structure also badly influences the serviceable life of synthesis precision and the sensor of whole weighing system simultaneously.
Summary of the invention
Technical matters to be solved by this invention provides a kind of Weighing cell module with buffer structure, improved the rig-site utilization performance of wide range structure LOAD CELLS in big load, large impact occasion, solved heavy shock loads simultaneously to the life-span of LOAD CELLS and the problem that influences of precision, especially hung to lay the effect of weighing in the middle of the weighing system of material by driving in metallurgical, harbour and big material metage field remarkable.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of buffer-type Weighing cell module, comprise LOAD CELLS and sensor pressure head, described sensor pressure head is arranged on the described LOAD CELLS, it is characterized in that described sensor pressure head top is provided with buffer gear, described buffer gear comprises upper substrate, dish formula reed group and is positioned at the infrabasal plate of sensor pressure head top, dish formula reed group is provided with reverse position-limit mechanism between described upper substrate and the infrabasal plate between upper substrate and infrabasal plate.
The upper substrate below arranges the buffering pressure head, the top of infrabasal plate is provided with opening outer cylinder body up, and dish formula reed group is placed in the outer cylinder body, and the lower end of buffering pressure head is pressed in the top of dish formula reed group, the external diameter of buffering pressure head is less than the internal diameter of outer cylinder body, and the buffering pressure head can be pressed in the described outer cylinder body.
Be provided with reference column in the middle of the described outer cylinder body, form the ring cavity of placing dish formula reed group between described outer cylinder body and the reference column, described pressure head is downward opening inner barrel, the internal diameter of described inner barrel is greater than the diameter of reference column, described reference column stretches in the described inner barrel, leaves a segment distance between the top of described reference column and the endoporus of the inner barrel bottom.The buffering pressure head designs for cooperating outer cylinder body, it mainly is the decrement of control dish formula reed group, thereby guarantee that buffering reaches application request, dish formula reed group is mounted in the outer cylinder body, there is a reference column at the position, bosom in outer cylinder body, it act as and guarantees that dish formula reed group can be normally vertically stressed, and can prevent moving horizontally of dish formula reed group.
Dish formula reed group vertically is formed by stacking by at least two pairs of dish formula reeds, the concave face of adjacent two dish formula reeds towards opposite or identical towards.
Described reverse position-limit mechanism is made up of many spacing connecting rods.Spacing connecting rod is installed below outer cylinder body, main effect is then to remove the dish formula reed group of load fashionable dress in outer cylinder body on this module again and have reciprocal power and eject when load is added in, after ejecting certain altitude, can make the top of impact damper pressure head disengaging outer cylinder body and cause equipment failure, limit impact damper pressure head bounce-back displacement so be provided with spacing connecting rod herein.
Comprise described fixed mount, described fixed mount lower end is provided with firm banking, and LOAD CELLS is fixed on the described firm banking, and described infrabasal plate is fixed on the upper end of fixed mount, the firm banking below is provided with the module lower installation board, and upper substrate is provided with the module upper mounting plate.
Described sensor pressure head is fixed on the fixed head, and described fixed head and infrabasal plate interfix.
Compared with prior art, advantage of the present invention is that sensor pressure head top adds buffer gear, when load acts on the buffer gear, load is conducted to dish formula reed group, dish formula reed group has stable and fixing elasticity coefficient, mutually a certain amount of decrement should be arranged as load effect meeting, when getting rid of, load can return to the original form again, utilize these characteristics just can the process of a transition buffer be arranged to being carried in load on the LOAD CELLS, the introducing of this process just can significantly reduce the directly stressed of sensor, when load after the buffering of impact damper, it is mild that load can become, thereby just can not produce the overall performance that destroys sensor because of moment impact, the elasticity coefficient of dish formula reed group is to design according to the actual needs at scene or the maximum load of sensor in the impact damper, the buffering course of impact damper is not to make the reed group all reach buffer limit, but the buffering capacity that reaches 70% load gets final product, because the weighing process of LOAD CELLS is to need stable stress point, so can make the load of the weighing of wanting act on the LOAD CELLS fully at 70% o'clock what dish formula reed group was compressed to the design decrement, with this big load impacting that guarantees the weighing precision of LOAD CELLS and can well prevent LOAD CELLS, prolonged the serviceable life of LOAD CELLS greatly, the small and exquisite exquisiteness of this structure Design, install, it is all very convenient to change, and had abandoned in the past and can only carry out the installation of snubber assembly to wide range weighing apparatus on the scale body.
