Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-4, the present invention provides a quantitative tightening device for the existing problems, comprising:
the base mechanism comprises a base 2 and a bottom plate 1, wherein the base 2 is arranged on the upper side of one end of the bottom plate 1; one end of the moving mechanism is provided with a flange 4, and the outer side of the lower end of the flange is movably sleeved with a bearing 3; a horizontal arc-shaped channel is further arranged in the flange 4, the arc-shaped channel is further connected with a lever 6, one end of the lever 6 is arranged in the arc-shaped channel, the other end of the lever is provided with a support 5, a pulley 7 is arranged in the support 5, the pulley 7 is in sliding connection with the support 5 through a pulley shaft 10, a hanging rope 8 is further arranged on the pulley 7, one end of the hanging rope 8 is connected with the other end of the lever 6 through the pulley 7, and the other end of the hanging rope 8 is connected with a hanging gyroscope 9 through the pulley 7; the tightening mechanism is provided with a tightening carrier 44 at one end, the tightening carrier 44 is positioned at the upper end of the flange 4, a groove is further formed in the center of the upper end of the tightening carrier 11, a first tightening part 12 to be tightened is arranged in the groove, a second tightening part 13 to be tightened is connected above the first tightening part 12, and the second tightening part 13 is connected with a tightening wrench 14.
A circular groove is formed above the base 2, and the flange 4 is arranged in the circular groove through the bearing 3; the upper side and the lower side of the interior of the arc-shaped channel are provided with screw threads matched with one end of the lever 6; the bracket 5 is fixedly connected with the bottom plate 1 through bolts; the tightening carrier 11 is fixedly connected with the flange 4 through bolts; the base 2 is fixedly connected with the bottom plate 1 through bolts;
when the equipment works, firstly, the torque force to be achieved after the first tightening part 13 and the second tightening part 12 are assembled is determined, then the torque force is converted into a weight 9 with the same weight, and the weight is connected with the hanging rope 8 and hung on the equipment; when the screwing force of the screwing wrench 14 is smaller than the weight of the prepared gyroscope, the movement mechanism cannot move, and the first screwing part 13 and the second screwing part 12 are screwed slowly; when the force of the screwing wrench 14 for screwing the first tightening part 13 and the second tightening part 12 is equal to the weight of the matched hanging gyroscope, namely the torque force reaches the set requirement, in order to limit the torque force, the flange 4 and the lever 6 of the movement mechanism start to rotate to drive the hanging rope 8 to move, meanwhile, the hanging weight 9 also moves upwards, the torque force is protected from exceeding the set value, and the screwing work is finished.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
