Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of C shape to determine power clamping device, can determine concrete pressure, meets clamping pressure is had to the engineering application explicitly calling for.
The purpose of this utility model is achieved through the following technical solutions: a kind of C shape is determined power clamping device, it comprises C shape main body, screw rod, briquetting, depression bar, elastomeric element, guide rod and handle, the left part of C shape main body is connected with screw flight, the left end of screw rod is fixed with handle, right-hand member is provided with briquetting, the middle part of depression bar is provided with annular convex, the right part of C shape main body is provided with an accommodating cavity, the annular convex of depression bar and elastomeric element are arranged in accommodating cavity, C shape main body right part is connected with guide rod by screw thread, in guide rod, be provided with via, the left end of depression bar passes C shape main body right part, the right-hand member of depression bar is through the via of guide rod, depression bar right-hand member is provided with graduation mark.
Particularly, described elastomeric element is spring; Described handle is circle wheel ripple handle.
Further, the other mark of described graduation mark has force value.
The beneficial effects of the utility model are: the utility model is simple in structure, owing to being provided with pressure scale line, the clamping pressure of clear and definite C clamp well, and pressure scale line is set, can observe intuitively clamping pressure, meet clamping pressure is had to the engineering application explicitly calling for.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model is used view;
In figure, 1-handle, 2-screw rod, 3-briquetting, 4-depression bar, 5-C shape main body, 6-elastomeric element, 7-guide rod, 8-graduation mark, 9-annular convex, 10-part A, 11-part B.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As Fig. 1, shown in Fig. 2, a kind of C shape is determined power clamping device, it comprises C shape main body 5, screw rod 2, briquetting 3, depression bar 4, elastomeric element 6, guide rod 7 and handle 1, the left part of C shape main body 5 is threaded with screw rod 2, the left end of screw rod 2 is fixed with handle 1, right-hand member is provided with briquetting 3, the middle part of depression bar 4 is provided with annular convex 9, the right part of C shape main body 5 is provided with an accommodating cavity, annular convex 9 and the elastomeric element 6 of depression bar 4 are arranged in accommodating cavity, C shape main body 5 right parts are connected with guide rod 7 by screw thread, in guide rod 7, be provided with via, the left end of depression bar 4 passes C shape main body 5 right parts, the right-hand member of depression bar 4 is through the via of guide rod 7, depression bar 4 right-hand members are provided with graduation mark 8.Particularly, described elastomeric element 6 is spring; Described handle 1 is circle wheel ripple handle.
During use, staff regulates the distance of briquetting 3 and depression bar 4 by handle 1, and part (being part A10 and part B11 in Fig. 2) is put between briquetting 3 and depression bar 4, regulates handle 1, and part is fixing.Adopt circular wave handle more to contribute to the stressing conditions of staff's perception part, avoid part to cause damage.In the process that handle 1 regulates, depression bar 4 is stressed, cause spring 6(to select YA 1.2 * 6 * 22 GB/T 2089 standard springs, spring rate F '=11N/mm, maximum functional deflection fn=7.8mm, maximum pressure value Fn=86N) compression, depression bar 4 right-hand members extend to the right, during due to original state, the zero graduation line of depression bar 4 right-hand members and guide rod 7 right-hand justifieds, the distance of therefore extending to the right according to depression bar 4 can be determined force value.
Further, the described other mark of graduation mark 8 has force value.The definite of force value calculates according to Hooke's law formula F=F ' * S, and wherein: F is pressure, unit is N; F ' is spring rate, and unit is N/mm; S is working deformation amount, and unit is mm.Staff can intuitively read force value according to the force value of the graduation mark with guide rod 7 right-hand justifieds and mark, easy to use, meets clamping pressure is had to the engineering application explicitly calling for.
The above is only preferred embodiment of the present utility model, be to be understood that the utility model is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, modification and environment, and can, in contemplated scope described herein, by technology or the knowledge of above-mentioned instruction or association area, change.And the change that those skilled in the art carry out and variation do not depart from spirit and scope of the present utility model, all should be in the protection domain of the utility model claims.
