Based on above-mentioned saw blade strainer, the invention also discloses a kind of band sawing machine, described band sawing machine has the described saw blade strainer of aforesaid right requirement.
From above-mentioned technical scheme as can be seen, the upper whorl axial extension elongation can be locked after the length free adjustment according to following wheel shaft in the saw blade strainer among the utility model embodiment, make up and down wheel shaft has reduced the strict demand to the organism frame assembly in same plane; The principle of utilizing spring oppositely to compress of the present utility model, saw blade can change in different certain limits, and the pointer scale influence that not changed by length of saw blade, has improved the accuracy of pointer, has reduced the required precision of saw blade in length.
Description of drawings
The right view of the saw blade strainer that Fig. 1 provides for the utility model embodiment;
The front view of the saw blade strainer that Fig. 2 provides for the utility model embodiment.
The specific embodiment
For quote and know for the purpose of, the parts with the drawing reference numeral representative in the accompanying drawing are explained as follows below:
1, the recessed end holding screw of interior hexagonal, 2, hex nut, 3, upper whorl axial, 4, thrust bearing, 5, stage clip, 6, screw rod, 7, big handwheel, 8, the tensioning bearing, 9, the tensioning support, 10, locating piece, 11, hexagon-headed bolt, 12, regulating handle, 13, the fine setting locking device.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
A kind of saw blade strainer, shown in accompanying drawing 1-2, comprise upper whorl axial 3, tensioning support 9, the recessed end holding screw 1 of interior hexagonal, tensioning bearing 8, big handwheel 7, stage clip 5, screw rod 6, locating piece 10, thrust bearing 4, hex nut 2, hexagon-headed bolt 11 and regulating handle 12
One end of last arbor wheel 3 is arranged in the hole on the tensioning support 9, direction with upper whorl axial 3 axis normal on the tensioning support 9 is provided with screw, recessed end holding screw 1 of interior hexagonal and hex nut 2 cooperate with screw makes the recessed end holding screw 1 of interior hexagonal touch with being coupling of upper whorl axial 3, be used to lock upper whorl axial 3, tensioning support 8 is arranged on the tensioning bearing 8, and can move along tensioning bearing 8;
Two sides of tensioning bearing 8 are provided with hexagon-headed bolt 11, and hexagon-headed bolt 11 is fixed on described tensioning bearing 8 on the body of described band saw;
Screw rod 6 is threaded with described tensioning support 9, is used to adjust tensioning support 9 and moves up and down;
Regulating handle 12 and trimming handle locking device 13 are arranged on the tensioning bearing 8, are used for fine setting.
The band saw strainer course of work that the utility model embodiment provides: on take turns be installed in upper whorl axial 3 after, between the last lower whorl of band saw saw blade is installed, rotate big handwheel 7, because the screw-internal thread fit on screw rod 6 and the tensioning support, screw rod 6 rotations drive tensioning support 9 and move up, and begin to press down stage clip 5 after saw blade has tensile force.Continue the big handwheel 7 of rotation, reach the tensile force of regulation until saw blade.
This strainer can adapt to the saw blade with interior all lengths at length difference 80mm, and the indication after the saw blade tensioning is unaffected.If when reason is the big handwheel 7 of rotation this moment saw blade not have tensile force be compression press spring not, the locating piece 10 that connects saw blade tensioning indication does not produce displacement yet, so as long as in wheel moves up and down the scope that is not subjected to interfere, the variation of length of saw blade can not influence the accuracy of tensioning indication.
The upper whorl axial extension elongation can be locked after the length free adjustment according to following wheel shaft, and wheel shaft is in same plane about making.
The bolt on the right side of this mechanism can move forward and backward in the groove of body, determines the locking of parallel back with body.
Key point of the present invention is the principle of utilizing spring oppositely to compress, and saw blade can change in different certain limits, and the pointer scale influence that not changed by length of saw blade.Improved the accuracy of pointer, reduced the required precision of saw blade in length.
Axial adjustment and beat by upper whorl axial are regulated, and can adjust lower whorl very easily in one plane, have reduced the strict demand to the organism frame assembly.
