Description
Technical field
The present invention relates to a kind of electric tool, particularly a kind of screw thread is decided path increment flexible assembly mechanism lower cone parts, is applicable to deciding in path increment assembling mode of screw thread.
Background technology
At present, screw thread decide path increment assembling mode, particularly be attended by in unconventional angle flexible assembly, mostly adopt artificial contraposition, then realize the assembling needs by the manual technology mode that screws in operation of the instruments such as screwdriver, spanner.Its weak point: 1. the scope of application is restricted, and can't satisfy the matching requirements of precision size workpiece; 2. assemble and improperly will scratch the sliding dental phenomenon of part and screw thread; 3. each how many degree of depth that screw in, the much moment of employing are all leaned on people's estimation, and is uncontrollable; 4. efficiency of assembling is low, and a people once can only assemble a part, and the impact of restricted people's subjective factor, takes time and effort.And this assembling mode is a large amount of existence the in production and processing.
Chinese patent application CN201020596207.7 is the installation for the limit rivet; Chinese patent application CN88211606.1 is the installation for wood screw or tapping screw, and is not assembling.Chinese patent application CN201120016775.X, although be also screw thread assembler, its scope of application only limits to the use of the so little handicraft articles of flashlight, has significant limitation, and can't realize flexible assembly, also can't realize deciding the path increment Screw assembly.What also there is no at present to satisfy screw thread decides the especially patent of the industrial circle of flexible assembly of path increment.
Summary of the invention
Purpose of the present invention is exactly in order to overcome in existing Screw assembly mode the technique weak point in particularly flexible assembly, provides a kind of screw thread to decide path increment flexible assembly mechanism lower cone parts.
the technical solution used in the present invention is: a kind of screw thread is decided path increment flexible assembly mechanism lower cone parts, comprise the lower cone friction member, the first straight spring, the powder metallurgy bearing shell, the chassis, the powder metallurgy axle sleeve, lower cone, gum sleeve, lower cone friction member hold-down screw, dive key, the dive key hold-down screw, its structure and connected mode are: the first straight spring is fixed on the groove of lower cone, dive key is arranged on position, the corresponding hole of lower cone by hold-down screw, the powder metallurgy axle sleeve is assembled on the chassis, the powder metallurgy axle sleeve be used in conjunction with the powder metallurgy bearing shell of keyway, the lower cone friction member is screwed in the lower cone upper end, the lower cone friction member is rough surface, elastomeric material with larger coefficient of friction, due to the friction member rough surface, has larger coefficient of friction, can be by the effect of frictional force, torsional moment is transferred to lower cone.
Have the oilhole of oiling on described powder metallurgy axle sleeve.
The gum sleeve that is used for fixing the throw head is equipped with in described lower cone lower end.
The operation principle that described screw thread is decided path increment flexible assembly mechanism lower cone parts is:
In the time of assembling whorl work piece on position, part Screw assembly hole, the operator pulls the handle on lifting arm, slowly the position, hole on part is mixed up the shaft core position of throw head, after workpiece and tool heads are worked good, starter motor, in screwed hole position with screwed workpiece precession part, when touching stop screw, lifting arm namely stops to bottom offset and electric machine rotation.
The invention has the beneficial effects as follows:
1, the utilization of torque drive principle makes operation more laborsaving, has saved the operating time;
2, make the whorl work piece can flexible assembly, reduced screw thread inclination extrusion sections screw thread hole wall in the assembling process and caused the appearance of the phenomenons such as sliding tooth;
3, compact conformation, easy to use, safeguard simple.

The specific embodiment
As shown in Figure 1, screw thread of the present invention is decided path increment flexible assembly mechanism lower cone parts, comprises lower cone friction member 15, the first straight spring 16, powder metallurgy bearing shell 17, chassis 18, powder metallurgy axle sleeve 19, lower cone 20, gum sleeve 21, lower cone friction member hold-down screw 23, dive key 24 and dive key hold-down screw 25.Its structure and connected mode are: the first straight spring 16 is fixed on the groove of lower cone 20, and dive key 24 is arranged on lower cone 20 positions, corresponding hole by dive key hold-down screw 25.Powder metallurgy axle sleeve 19 is assembled on chassis 18, powder metallurgy axle sleeve 19 is used in conjunction with powder metallurgy bearing shell 17 with keyway, have the oilhole of oiling on powder metallurgy axle sleeve 19, lower cone friction member 15 is fixed on lower cone 20 upper ends by lower cone friction member hold-down screw 23.Be provided with in lower cone 20 lower ends the gum sleeve 21 that is used for fixing the throw head.
The operation principle that described screw thread is decided path increment flexible assembly mechanism lower cone parts is:
Rotary body moves down on main transmission and control assembly, after 15 engagements of lower cone friction member, produces frictional force, by the effect of frictional force, torsional moment is transferred to the lower cone parts.Under the frictional force of the upper rotary body in active force transmission and control assembly and the effect that moves down, dive key 24 is done the relative displacement campaign in the keyway of powder metallurgy bearing shell 17, under the effect of principal and subordinate's rotation, drive powder metallurgy bearing shell 17 rotation in the lump simultaneously; The throw head gently in the screwed hole position with screwed workpiece precession part, simultaneously, under the effect of stopping means and gum sleeve 21, by controlling the displacement of lower cone 20, can be controlled the path increment of Screw assembly flexibly.
