See also shown in Fig. 1,2.The embodiment of overload safeguard for tensometer of the present invention is in order to placing between push-pull effort source and the pull and push dynamometer with the protection pull and push dynamometer, comprising:
One base plate 11, its top have first groove 111 and second groove 112;
One first block 12 has a through hole 121; The bottom of first block 12 places in first groove 111 of base plate 11, and with base plate 11 secure bond;
One second block 13 has a through hole 131; The bottom of second block 13 places in second groove 112 of base plate 11, and with base plate 11 secure bond;
One body 14 has pars intermedia 141, first cylindrical portion 142 and second cylindrical portion 143; First cylindrical portion 142 and second cylindrical portion 143 are connected to the dual-side of pars intermedia 141, and respectively in the through hole 131 of the through hole that places first block 12 121 of movable and second block 13; Pars intermedia 141 all has the gap respectively and between first block 12 and second block 13; The outboard end of first cylindrical portion 142 is in conjunction with one first screw rod 144; Body 14 has an axial slots 145, and slotted eye 145 extends to the outer side edges of second cylindrical portion 143; Pars intermedia 141 has at least one long slot bore 146 in addition; The bottom of long slot bore 146 is communicated with slotted eye 145; The bottom of pars intermedia 141 is tabular, places base plate 11 tops;
At least one elastic component 15, its upper end is incorporated into the outboard end of long slot bore 146, and its bottom elasticity stretches in the long slot bore 146; Elastic component 15 comprises that a conjunction 151 is incorporated into the upper end of a compression spring 152, and the bottom of compression spring 152 is in conjunction with a ball 153; The outboard end of conjunction 151 and long slot bore 146 can be respectively the structure of screw rod and screw, makes both secure bond;
One column 16 is in the movable slotted eye 145 that is placed in body 14; Column 16 places the ends in the slotted eye 145 to have and the corresponding annular recess 161 in elastic component 15 bottoms, the ball 153 that groove 161 can ccontaining elastic body 15 bottoms; The outboard end inside of column 16 has screw 162, with second screw rod 163 that is spirally connected, by the overhang of screw 162 adjustment second screw rod 163 that is spirally connected by second screw rod 163, to cooperate different pull and push dynamometer 30.
See also shown in Fig. 3,4,5.Overload safeguard for tensometer of the present invention is when normal operating condition, and the ball 153 of elastic component 15 places in the groove 161 of column 16, makes column 16 and body 14 be connecting state, as shown in Figure 3; At this moment, application of force source 20 can measure the size of application of force source 20 push-pull force outputs by bestowing pull and push dynamometer 30 by column 16 by bestowed the push-pull effort of body 14 by first screw rod 144 for pull and push dynamometer 30.When application of force source 20 can place the strength of groove 161 by the thrust of being bestowed body 14 by first screw rod 144 above ball 153, can make ball 153 break away from groove 161, and make column 16 and body 14 be the state of getting loose, be that body 14 can not drive column 16, make the pull and push dynamometer 30 that is resisted against second screw rod 163 can not bear the excessive thrust in application of force source 20, and the pars intermedia 141 of body 14 is resisted against second block 13, as shown in Figure 4.When application of force source 20 imposes on the excessive pulling force of first screw rod 144, when making ball 153 break away from groove 161, also can make column 16 and body 14 be the state of getting loose, be that body 14 can not drive column 16, and make application of force source 20 excessive pulling force can not force in pull and push dynamometer 30, this moment, the pars intermedia 141 of body 14 was resisted against first block 12, as shown in Figure 5.
See also shown in Figure 1.The present invention utilizes ball 153 elasticity of the bottom of elastic component 15 to stretch in the groove 161 of column 16, when making column 16 and body 14 be connecting state, can measure that 20 outputs of application of force sources push away, the size of pulling force for pull and push dynamometer 30.The maximum that the visual pull and push dynamometer 30 of the present invention can bear pushes away, pulling force, adjust the amount of being compressed that conjunction 151 stretches into the length adjustment compression spring 152 in the long slot bore 146, make column 16 and the required strength of body 14 separated attitudes with adjustment, this strength is equivalent to that the maximum that pull and push dynamometer 30 can bear pushes away, pulling force, when the pushing away of application of force source 20, when pulling force surpasses this strength, can make column 16 be the state that separates with body 14, the pushing away of application of force source 20 overload, pulling force promptly can not impose on pull and push dynamometer 30, and damage pull and push dynamometer.
The present invention can avoid pull and push dynamometer in the measurement process because of operated overload causes damage, and can reduce, and increase product required cost in R﹠D process because of tautness meter damages.
