Detailed description of the invention
For making that architectural feature of the present invention and effect of reaching are had and further understand and be familiar with, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1, a kind of hand moment of torsion screw rotating tool, comprise handle 1, extension bar 2 and rear stifled 3, rear stifled 3 are connected with the tail seal of handle 1, one end of extension bar 2 extend in handle 1, extension bar 2 stretches out on one end of handle 1 and is set with a sleeve 4, and the termination that extension bar 2 extend into the one end in handle 1 is bulb 21 in many ways, is provided with cavity 11 in the afterbody of handle 1.
As a modification of the present invention, as shown in Figure 2, in this cavity 11, be provided with snap-in structure 7, in many ways bulb 21 is stuck in this snap-in structure 7, the left side that is positioned at snap-in structure in cavity 11 is provided with plane bearing assembly 5, snap-in structure 7 comprises vexed button 71 and the actuating sleeve 72 with square hole, and one end that extension bar 2 stretches into handle 1 is stuck in vexed button in 71 button hole through the square hole of actuating sleeve 72 and by termination 21, and actuating sleeve 72 can drive vexed button 71 and extension bar 2 to rotate with respect to plane bearing assembly 5.
Further improve as of the present invention, as shown in Figure 1, Figure 3, in cavity 11, be positioned at snap-in structure and be provided with needle roller multistation axial clutch structure 8 near a side of handle 1 afterbody, be connected with a stage clip 6 in this needle roller multistation axial clutch structure 8 near a side of handle 1 afterbody, between the other end of this stage clip 6 and rear stifled 3, be provided with stage clip telescopic regulation structure 9.
Needle roller multistation axial clutch structure 8 comprises needle roller base 81, needle roller 82, ball set 83, ball base 84, slip spring abutment 85 and steady pin 86, ball base 84 is sleeved on slip spring abutment 85, on needle roller base 81, be provided with the groove corresponding with needle roller 82 87, needle roller 82 is arranged in this groove 87, the diameter of needle roller 82 is greater than the degree of depth of this groove 87, ball base 84 is provided with the arc groove extending along circumferentially, ball set 83 is located in this arc groove by ball support 88, needle roller 82 setting corresponding to ball 83, needle roller base 81 contacts with the ball 83 on ball base 84 by needle roller 82, and needle roller base 81 can be with respect to ball base 84 rotation within circumferentially, in the time rotating, needle roller 82 and ball 83 are in sliding friction state, the quantity of ball set 83 is even number, between adjacent ball between two in ball base 84 arc grooves, multiple circular gaps are formed, the plurality of circular gap measure-alike, needle roller 82 drops on while rotation in this circular gap, the peak of ball 83 is all in same plane, needle roller 82 and be tending towards constant to the frictional force between each ball, when each rotation extension bar 2, the moment of torsion output valve of extension bar 2 is all in a steady state value, this revolves tool and just there will not be in use screw to revolve the tight or tension revolving and the phenomenon of the stripped thread that occurs.
As shown in Figure 4, actuating sleeve 72 and needle roller base 81 are mutually fixed and link together, and vexed button 71 is arranged on actuating sleeve 72 and needle roller base 81 engages in formed cavity.Slip spring abutment 85 is provided with through hole 89, and the end play of this through hole 89 is greater than the diameter of steady pin 86, and steady pin 86 passes this through hole 89 and is fixedly connected with the shell of handle 1.
Stage clip telescopic regulation structure 9 comprises adjusts screw 91 and stop nut 92, slip spring abutment 85 is provided with convex shoulder accordingly with adjustment screw 91, stage clip 6 is sleeved on this convex shoulder, adjust screw 91 and move left and right to control the flexible of stage clip 85 by rotation, by the flexible active force of stage clip 6 to slip spring abutment 85 of controlling of stage clip 6.
When the torque limit of this screw rotating tool too hour, adjusting screw 91 is moved to the left, stage clip 6 is just in further compressive state, form larger compression stress, compression stress is passed to the ball 83 on ball base 84 by slip spring abutment 85, and when ball 83 contacts with needle roller 82, its contact force becomes larger, thereby it is large that the force of sliding friction between needle roller 82 and ball 83 just becomes, the extension bar 2 outwards torque of output also will become large thereupon; In the time not reaching requiring of operation by the adjusting of adjusting screw 91, convertible thicker stage clip, reaches needed moment of torsion.
In the time that the torque limit of this screw rotating tool is too large, adjusting screw 91 moves right, stage clip 6 is just in relaxed state, form less compression stress, compression stress is passed to the ball 83 on ball base 84 by slip spring abutment 85, and when ball 83 contacts with needle roller 82, its contact force becomes less, thereby the force of sliding friction between needle roller 82 and ball 83 just diminishes, and the output torque of extension bar 2 also will diminish thereupon; In the time not reaching requiring of operation by the adjusting of adjusting screw 91, convertible thinner stage clip, reaches needed moment of torsion.
According to the requirement of different screws, extension bar 2 can be six side's extension bars, and bulb 21 is six side's bulbs in many ways, and extension bar 2 also can be cubic extension bar, extension bar from all directions, and bulb 21 also can be cubic bulb and all directions bulb in many ways.
Due to needle roller 82 with the sliding friction number of times of ball 83 more than tens thousand of times, in order to increase the frictional strength of needle roller 82, needle roller 82 is preferably wolfram steel rod.
In order to increase the service life of revolving tool and the weight that alleviates handle, handle 1 is made up of hydronalium.
More than show and described general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what in above-described embodiment and description, describe is principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain that the present invention requires is defined by appending claims and equivalent thereof.
