Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, this rotating shaft comprises main part 100, first joint 200 and the second joint 300, described first joint 200 and the second joint 300 lay respectively at the both sides of main part 100, and the shape of the cross section of described first joint 200 and the second joint 300 is regular hexagon, first joint 200 is provided with circular cam 400, circular cam 400 offers through hole, described first joint 200 is inserted in through hole, described second joint 300 can drive the first joint 200 to rotate, and make circular cam 400 synchronous axial system, assembly department 500 is fixed with in the front end of the first joint 200, circular groove 510 is offered away from one end of the first joint 200 at assembly department 500.
The cross sectional area of above-mentioned first joint 200 and the second joint 300 is equal and the shape of cross section is regular hexagon, and the cross section of main part 100 is circular, and the cross sectional area of the first joint 200 and the second joint 300 is all less than the cross sectional area of main part 100, thus step is formed between the first joint 200 and main part 100, also step is formed with between the second joint 300 and main part 100, the setting of main part 100 in order to avoid the first joint 200 and the second joint 300 spacing in the axial direction larger, and cause in the process driving the first joint 200 to rotate at the second joint 300, there is the generation of damage phenomenon in the joint between the first joint 200 and the second joint 300, thus improve the rigidity of rotating shaft entirety, improve the working life of rotating shaft.
Preferably, second joint 300 offers driving hole, in the process that reality uses, user rotates the second joint 300 by using supporting spanner, and improve utilization efficiency, spanner fore-end can be arranged in driving hole, rotating spanner can drive the second joint 300 to rotate, because the second joint 300 and the first joint 200 are arranged at main part 100 both sides, thus the second joint 300 can drive the first joint 200 synchronous axial system, and circular cam 400 circumference is rotated.
Circular cam 400 offers the through hole corresponding with the first joint 200, the shape of through hole is also in regular hexagon, thus avoid circular cam 400 relative first joint 200 and circumferential offset occurs and reduces the generation of the transmission accuracy phenomenon between circular cam 400 and the first joint 200, improve the transmission accuracy of rotating shaft, in installation process, cross sectional area due to assembly department 500 is less than the cross sectional area of the first joint 200, thus ensure that circular cam 400 can be sheathed on the first joint 200 from assembly department 500 side, and due to the cross section of the first joint 200 be Hexagon, thus circular cam 400 can with the first joint 200 synchronous axial system, circular cam 400 can along the first joint 200 slippage in the axial direction simultaneously, thus can adjust the position of circular cam 400 according to actual needs, expand the using scope of rotating shaft, improve the utilization efficiency of rotating shaft.
Preferably, circular cam 400 offers arc notch 421, in the process of work, rotate the second joint 300 and can drive the first joint 200 synchronous axial system, and make the arc notch 421 of circular cam 400 be arranged in specified position and carrying out for rotating shaft position limits, corresponding adjustment can be carried out to the position of arc notch 421 according to actual needs simultaneously, thus the slewing area of energy countershaft carries out corresponding adjustment, expand the Applicable scope of rotating shaft, improve the utilization efficiency of rotating shaft.
Further, assembly department 500 is also fixed with in the first joint 200 front end, and the cross sectional area of assembly department 500 is less than the cross sectional area of the first joint 200, thus be formed with step in the joint of the first joint 200 and assembly department 500, in installation process, when assembly department 500 can be inserted on base plate, first joint 200 portion end surface can be resisted against on base plate, add the area of contact of the first joint 200 and base plate, improve the steadiness that rotating shaft is installed, avoid when rotating shaft is vacillated now to the left, now to the right the generation of phenomenon in rotation process, simultaneously because the cross sectional area of assembly department 500 is less than the cross sectional area of the first joint 200, thus facilitate the installation of circular cam 400, improve installation efficiency.
Circular groove 510 is also offered away from first joint 200 one end at assembly department 500, when assembly department 500 is inserted in base plate, in circular groove 510, ring buckle is installed, and the diameter of ring buckle is greater than the diameter of assembly department 500, thus be resisted against the lower surface that plate upper surface and ring buckle are resisted against base plate due to the first assembly department 500 portion end surface, ensure that rotating shaft is arranged at the steadiness installed, also ensure that rotating shaft is movably set on base plate simultaneously, rotating shaft circumference can be rotated on base plate.
Also chamfering is provided with away from the end face of the first joint 200 at assembly department 500, the setting of chamfering eliminates the sharp edge of assembly department 500 end face, avoid sharp edge in the process of installing in rotating shaft and operator is caused to the generation scratching phenomenon, also facilitate assembly department 500 is inserted on base plate simultaneously, improves the installation efficiency of rotating shaft.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
