Description
Technical field:
The invention belongs to hardware & tools preparing technical field, relate to and a kind ofly can screw and nut be clamped or be loosened the monkey wrench, particularly a kind of continuous-operation type adjustable wrench of the continuous rotation operation of rotation.
Background technology:
At present, in five metals processing preparation industry, particularly at the industry field of machine-building and operation, the instrument often using has hammer, pliers and various spanner, monkey wrench is in spanner, to use one of modal rotating tool, no matter be to tighten the screw or loose nut, or rotates various pipelines, monkey wrench is that utilization rate is the highest, is also the hand-operated tools of most convenient.Existing adjustable spanner structure feature limits the continuous rotation of spanner in rotary course, generally in use, rotate after half-turn or most circle, to decontrol spanner, after changing in addition a upper/lower positions, be rotated again, this not only loses time, and for the screw under some occasion, the mode in this change orientation is relatively difficult to realize; The existence of these shortcomings determines mainly due to mobile's structure of existing monkey wrench and the annexation of fixed body structure.At present, use on the market and the monkey wrench that can rotate continuously or operate sold there is not yet concrete structure example, also there is no pertinent literature report.So the monkey wrench of a kind of operation of rotary type continuously of exploitation and design preparation is necessary.
Summary of the invention:
The object of the invention is to overcome the shortcoming that prior art exists, seek to design a kind of architecture basics by means of existing monkey wrench, by being replaced by newly-designed mobile structure, substitute original mobile structure, realize the operated novel adjustable spanner of continuous rotation, can realize and tighten continuously or unscrew screw, the parts such as nut, and jaw working size equates with the basic size value that is rotated part time job size, guaranteeing the working face of jaw and being rotated between the working face of part does not have nominal clearance, same turning moment, between the working face of jaw and part, produce less active force, improve spanner and the service life that is rotated part time job face, utilize the manufacturing process of existing common adjustable wrench, equipment and production management can realize the manufacturing without changing, easy to use, increase work efficiency and simple in structure, be convenient to implement, in auto industry, equipment manufacture, the aspects such as construction operation have wide practical use.
To achieve these goals, the present invention is on the basis of common adjustable wrench, mobile's jaw is designed to independently standardized component, the moving jaw of common adjustable wrench is unloaded, load onto this mobile jaw, form continuous-operation type adjustable wrench, its agent structure comprises worm screw, pressure head, connecting rod, fulcrum post, back-moving spring, fixed body, Tui Binghe mobile; Fixed body is that existing common adjustable wrench removes the component body after moving jaw; Mobile as jaw is constituted by worm screw, pressure head, connecting rod, fulcrum post and back-moving spring; Worm screw is identical with common adjustable wrench with the annexation between fixed body, can realize the adjusting of jaw size; Worm tooth adopts the physical dimension of common adjustable wrench so that with the fixed body of common adjustable wrench on wrom tooth engagement; Between worm screw and connecting rod, for moving movement is secondary, is connected, mobile direction is parallel between worm screw and fixed body mutually mobile direction mutually, can realize reversion and making a concession and move; Between connecting rod and pressure head, be connected to gyration pair, gyroaxis is parallel to the working face of pressure head, perpendicular to the mutual moving direction between worm screw and connecting rod, can realize between pressure head and worm screw engagement with separated; Between pressure head and worm screw, be the engagement of monodentate dental inlay, in forward duty, both mesh together, and transmit work moment; At reversion rollback state, both are separated from each other, and allow connecting rod with respect to movable press head, realize and making a concession; Back-moving spring is realized pressure head self-return to forward duty, realizes the working face of pressure head simultaneously and is rotated part time job face Continuous Contact, avoids impact type contact to cause working face to damage; Dental inlay mesh tooth face between pressure head and worm screw is the trapezoidal flank of tooth, and the angle of inclination of the flank of tooth is decided by that the peak of pressure head is to the distance of fulcrum post axis, and the flank of tooth is the pressure head peak wraparound rotating tangent line of axis of shipping and reselling on another market; Pressure head working face front end is the face of cylinder, and the axis that cylindrical radius is fulcrum post is to the distance of pressure head working face, and the face of cylinder is coaxial and tangent with pressure head working face with fulcrum post; Under the certain condition of adjustable spanner structure size, the position of fulcrum post is as far as possible near the fixed body front end of monkey wrench, and this is decided by the intensity of pressure head, and on common pressure head, the hole wall of pin-and-hole is not less than 2 millimeters to the minimum range of pressure head front end face; Back-moving spring, for guaranteeing the critical component of continued operation, has the spring steel wire structural formula back-moving spring of two circular sections to be designed to quick-change type part; The right side of worm screw is shaped with hole and the groove that back-moving spring is installed, and back-moving spring long-tail portion inserts in the hole, and the part intersecting vertically with long-tail portion is sunken in groove; Installing space at back-moving spring is little, and in the restricted situation of overall size of back-moving spring, this structure is convenient for changing the back-moving spring that fatigue rupture loses enough reset forces.
Gyration pair of the present invention refers between two members that are connected, and can mutually rotate and can not mutually move, and an external cylindrical surface is combined with another inner cylinder face; Moving movement pair refers between two members that are connected, movement can not be rotated mutually mutually, the structure realizing is the combination of non-inside and outside circle cylinder, comprise that square hole is combined with square shaft, elliptical shaft is combined with elliptical aperture, or the structure of inside and outside circle cylinder added limitations rotation, as additional straight pin and feather key etc.; What the present invention adopted is the structure of the additional feather key of inside and outside circle cylinder, and it is the plank frame on the face of cylinder that link design is become to one end, and the axis on the face of cylinder and the plane of symmetry of plate are perpendicular to the working face of pressure head and the axis of fulcrum post.
The present invention compared with prior art, owing to having adopted by the basal body structure of existing normal activity spanner fixed body, match with newly-designed mobile structure, form continuous-operation type adjustable wrench, its novel structure, make simply, easy to install, low cost of manufacture, continued operation is flexible, safe and reliable.
