Abstract
The invention relates to the technical field of column type weighing sensor, in particular to an integral type self-resetting column type weighing sensor. A column type elastic body is arranged inside a rigid shell and high force self reset can be achieved through a base and the shell. The shell and the base form an integral structure through welding, and the double spherical surface tumbler type column type elastic body keeps a soft connection with an upper ram and an integral structure with rigidity and softness is formed. The shell and the base are connected into a whole to form a bottom sealing structure, and a seal rubber ring is compressed tightly on the shell through a shell cover to form a top sealing structure and has good waterproof performance. When the weighing sensor is used, the weighting sensor is directly placed below a weighting device, no centering and positioning are needed, on other accessories or modules are needed, and the installation is convenient. The seal rubber ring, the shell and a damping device cooperate with each other to form an automatic reset device which has the effects to the high force self reset of the column type elastic body and can prevent the column type elastic body from excessively inclining, so that the quick high force reset of the column type elastic body is guaranteed, and the measurement accuracy is improved.

Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
embodiment 1.
As shown in Fig. 1 ~ Fig. 7, a kind of monoblock type Self-resetting column weighting sensor, the seaming chuck 1 set gradually from top to down, column type elastomer 2 and base 3, also comprise shell 5, O-ring seal 6, planchet block 8, for the damping unit 4 that makes column type elastomer 2 reset and the casing cover 7 for press seal cushion rubber 6, described shell 5 is connected with described base 3, described column type elastomer 2 is arranged in described shell 5, described planchet block 8 is arranged between described column type elastomer 2 and described base 3, and described O-ring seal 6 is tightly connected described seaming chuck 1 and described shell 5.
By shell 5 by seaming chuck 1, the one-piece construction that column type elastomer 2 and base 3 are connected, during use, the present invention is directly positioned over the below of weighing-appliance, weighing-appliance produces one to seaming chuck 1 and to weigh power, the power of weighing is passed to base 3 by cushion block 8 by column type elastomer 2, base 3 produces an opposition to by cushion block 8 araeosystyle elastic body 2, seaming chuck 1, cushion block 8 clamps column type elastomer 2, column type elastomer 2 is made to produce distortion, column type elastomer 2 is provided with foil gauge, the deformation force of foil gauge induction column type elastomer 2, measuring mechanism is connected by connecting line, obtain measurement data.Terminal box 9 is installed on shell 5, installs connecting line.The present invention need not centering locate, without the need to other annex or module, easy for installation.
When seaming chuck 1 is subject to the side force of weighing-appliance applying, O-ring seal 6 can play buffer action; When external force is excessive, casing cover 7 stops the skew of seaming chuck 1, and the scope of activities of seaming chuck 1 is restricted, and stops column type elastomer 2 over-tilting, and shell 5 plays the effects such as the impact of sealing and opposing external force araeosystyle elastic body 2; O-ring seal 6, shell 5 coordinate with damping unit 4 three, form automatic reset device, araeosystyle elastic body 2 has powerful Self-resetting and stops the effect of column type elastomer 2 over-tilting, and ensure that the rapid strong of column type elastomer 2 resets, measuring accuracy of the present invention is high.
As shown in Figure 6, when column weighting sensor is subject to the side force of weighing-appliance applying, seaming chuck 1 araeosystyle elastic body 2 produces a side force, column type elastomer 2 relative centre line is made to have a deviation angle a, damping unit 4 araeosystyle elastic body 2 has stronger reset force F, makes column type elastomer 2 Rapid reset automatically.As shown in Figure 7, deviation angle a and reset force F is linear, and along with deviation angle a increases gradually, reset force F also increases gradually.
Shell 5 and base 3 are welded to connect and are integrated, form the rigid structure of sealed bottom, being rigidly connected and can ensureing intensity of the present invention, make shell 5, base 3 has higher support strength, preventing the phenomenon that column type elastomer 2 side because causing during extraneous greater impact power is fallen better; And shell 5 has good sealing function with welding of base 3.Certainly, the shell 5 of the present embodiment also can be threaded with described base 3 and be integrated, as long as realize the rigid structure of sealing.
Column type elastomer 2 is arranged in shell 5, and O-ring seal 6 is pressed in shell 5 by casing cover 7, forms the structure of top seal.Particularly, casing cover 7 covers and is pressed in described O-ring seal 6; Casing cover 7 is arranged in seaming chuck 1, and the periphery of casing cover 7 is threaded with shell 5, and casing cover 7 and shell 5 is locked by screw, carrys out press seal cushion rubber 6, thus reach the effect of sealing by casing cover 7.
Because seaming chuck 1 must be in use movable, therefore the present invention adopts column type elastomer 2 to keep soft with seaming chuck 1 to be connected, form the hard and soft monolithic construction had both, so namely can ensure the dirigibility of seaming chuck 1, also ensure that the good sealing property of sensor.
Because the present invention generally uses out of doors, once water inlet, all performances all can decline, and even can not use, so must ensure good barrier propterty; Shell 5 and base 3 are welded to connect the structure being formed as one sealed bottom, O-ring seal 6 is pressed in shell 5 by casing cover 7, and form the structure of top seal, the present invention has novel hermetically-sealed construction, there is simple reliable water resistance, ensure service precision of the present invention.
Upper surface and the lower surface of column type elastomer 2 are sphere, form the column type elastomer of a kind of pair of sphere roly-poly type; The effect of automatic centering location is played in upper surface spherically, lower surface, and make the transmission of side force even, be convenient to column type elastomer 2 Rapid reset, described column type elastomer 2 is arranged at the center in described shell 5.
As shown in Figure 3, O-ring seal 6 described in the present embodiment comprises interior cushion rubber 61 and outer cushion rubber 62, groove 63 is provided with between described interior cushion rubber 61 and described outer cushion rubber 62, described interior cushion rubber 61 is connected with described seaming chuck 1, described outer cushion rubber 62 is connected with described shell 5, and described groove 63 is arranged between described seaming chuck 1 and described shell 5.
O-ring seal 6 is vulcanized rubber circle, and seaming chuck 1 is provided with a ring groove, and O-ring seal 6 embeds in ring groove by the mode of sulfuration, is connected to described seaming chuck 1.The lower surface of outer cushion rubber 62 contacts with the upper surface of shell 5, the lower surface of outer cushion rubber 62 and the upper surface of shell 5 are downward-sloping inclined-plane, the design on inclined-plane can prevent outer cushion rubber 62 from moving in parallel direction, prevent the mobile contraction in shell 5 of outer cushion rubber 62, ensure the sealing effectiveness of O-ring seal 6.The setting of groove 63, make interior cushion rubber 61 and outer cushion rubber 62 have the space of buffering, O-ring seal 6 has the space of dilatation.
When seaming chuck 1 be subject to side force and mobile time, seaming chuck 1 to interior cushion rubber 61 produce side to biasing force, because interior cushion rubber 61 and outer cushion rubber 62 have the space of buffering, make seaming chuck 1 have reset force, ensure column type elastomer 2 Rapid reset.
The cross section of the groove 63 of O-ring seal 6 described in the present embodiment is U-shaped, is convenient to machine-shaping, and interior cushion rubber 61 can be made to have enough cushion spaces with outer cushion rubber 62.The cross section of groove 63 can be also ripple type, has better cushion space, column type elastomer 2 is resetted more quickly.
