Description
Technical field
The invention belongs to tightening tool, is specially a kind of adaptive driving end.
Background technology
At present all using six square bolts or nut as main fastener in all kinds of mechanical equipments, in a mechanical equipment
The six side's fasteners that can use different size for different parts implement fastening.With the raising of production requirement, for machine
Tool equipment should all reach faster assembly or disassembly speed in terms of production and maintenance.But carry out six with the driving end of existing spanner
The problems of assembling of square fastener is：If using fork spanner, the spanner of a specification can only meet corresponding specification
Six side's fasteners, are assembling and are needing to prepare the spanner of plurality of specifications in maintenance process and carry out frequently replacing use, work
Efficiency is too low, while the problem of cause equipment cost high.If using adjustable wrench, although retractable driving end can adapt to compared with
Six sides of more specifications screw tight firmware, but assemble very cumbersome with the adjustment in maintenance process for driving end openings of sizes.For example,
When needing six side's fasteners of clamping and being locked, operating personnel want turn screw rod to open driving end, treat that driving end is caught in
Reverse turn screw rod is closing driving end until held tight after six side's fasteners.And exit driving end completing locking action
When, it is also necessary to driving end is opened and can smoothly exited by contra rotating screw again.Due to the screw rod one on existing adjustable wrench
As be to be realized by the rubbing up and down of thumb rotating, screw rod can just be made by not only needing to apply certain pressure during rubbing
Rotate, and be easy to have skidded between thumb and screw rod, so the driving end of existing adjustable wrench is operated when adjusting opening
Personnel are not laborsaving, and rubbing can cause thumb the sensation of discomfort repeatedly.
It can be seen from the above that using the driving end of existing spanner when carrying out production operation, have operate time-consuming and laborious, equipment into
The problem of this is high.
The content of the invention
In view of this, the present invention provides a kind of adaptive driving end, can rapidly adapt to six side's fasteners of different size, tool
Have and operate the characteristics of equipment cost time saving and energy saving, simple in structure is low.
The technical scheme is that a kind of adaptive driving end, including determine jaw and jaw living, it is characterised in that：Institute
State and determine jaw and be equipped with a sliding slot, the sliding slot is vertical with the clamping face for determining jaw, and the jaw living is equipped with a toothed rack, the rack
Vertical with the clamping face of jaw living, the rack is inserted into sliding slot；The lower section for determining jaw is hinged with one by pivot pin
Gear handle, the upper end of gear handle is gear, lower end is connector for connecting wrenching bar, and the gear is nibbled with the rack
Close.
Further, it is described to determine between jaw clamping face and gear arbor line angular range at 0 °~90 °.
Further, described to determine to be connected with reduction torsion spring between jaw and gear, the clamping face of the jaw living is with determining jaw
Clamping face fitting when reduction torsion spring restoring force it is minimum.
Further, the position that the lower end of the resetting spring is connected on gear is pressed from both sides positioned at jaw clamping face is determined with jaw living
Hold when face paste is closed on the extended line in produced gap, the top and bottom homonymy of the resetting spring simultaneously is connected close to determine jaw
The position of outer contour lower end.
Further, the section of the rack is cross, and the section of the sliding slot is adapted to the star section.
The beneficial effects of the present invention are since the rack of jaw living is plugged in the sliding slot for determining jaw, determines jaw and pass through
Pivot pin is hinged with gear, and jaw living is engaged by rack and pinion.So switch determines position of the jaw on gear, can to live
The rack of jaw produces walking on gear, and then changes the openings of sizes of driving end.Determine jaw forward direction switch, opening becomes larger；
Determine the reverse switch of jaw, opening diminishes.It follows that the configuration of the present invention is simple, operation is time saving and energy saving, can be very convenient quick
Adjustment driving end openings of sizes, adapt to six side's fasteners of different size with this, one multi-purpose, and to reduce equipment low.

Embodiment
It is below in conjunction with the accompanying drawings and specific real in order to make those skilled in the art more fully understand technical scheme
Applying example, the present invention is described in further detail.
As shown in Figure 1.A kind of adaptive driving end, including determine jaw 1 and jaw 2 living.It is equipped with as shown in Fig. 2, determining jaw 1
One sliding slot 9, the sliding slot 9 are vertical with the clamping face for determining jaw 1.As shown in figure 3, jaw 2 living is equipped with a toothed rack 10, rack 10
It is vertical with the clamping face of jaw 2 living.Rack 10 is inserted into sliding slot 9.The section of rack 10 may be designed as cross, correspond to therewith
9 section of sliding slot adapt to star section.The lower section for determining jaw 1 is hinged with a gear handle 5 by pivot pin 4.Determine jaw folder
Angular range is at 0 °~90 ° between holding 5 axis of face 7 and gear handle.As shown in figure 4, the upper end of gear handle 5 is gear 11, under
Termination is the connector for connecting wrenching bar 6.Rack 10 on jaw 2 living is engaged with the gear 11 on gear handle 5.When switch is determined
For jaw 1 in the angle on gear 11, jaw 2 living produces walking with rack 10 on gear 11, and then realizes opening for driving end
Mouth size.
It can automatically reset, therefore determine between jaw 1 and gear 11 after six side's fasteners are departed from for the ease of driving end
Reduction torsion spring is connected with, as shown in Figure 1.It should be noted that when the clamping face of jaw 2 living is bonded with determining the clamping face of jaw 1
When, the restoring force of reduction torsion spring is minimum.Using the axis of gear handle 5 as line of demarcation, the lower end of resetting spring 3 is connected to gear 11
On position be located at determine jaw clamping face 7 with work jaw clamping face 8 be bonded when produced gap extended line on；Resetting spring 3
Top and bottom homonymy and be connected close to determine the position of 1 outer contour lower end of jaw.
As one embodiment of the present of invention.As shown in figure 5, as the angle a for determining jaw clamping face 7 and 5 axis of gear handle
At=0 °, driving end is closure state.At this time, it is initial bit to determine the location of jaw 1 and jaw 2 living.As shown in fig. 6, work as
When determining 0 ° of angle, 90 ° of the ＜ a ＜ of jaw clamping face 7 and 5 axis of gear handle, driving end is in an open state.
The course of work of the present invention is specific as follows：A wrenching bar 6 is co-axially mounted in the lower section of gear handle 5.Needed when being scheduled on
When being clamped to six side's fasteners, as shown in fig. 6, driving end opening direction b switches wrenching bar 6.At this time, jaw is determined
Angle a gradually increases by 0 ° of clamping face 7 and 5 axis of gear handle, jaw 2 living starting row on gear 11 with rack 10
Walk, driving end is opened, and be open gradually increase.When six side's fasteners enter driving end opening in, no matter driving end open it is big
It is small whether suitable, only need to be to driving end closing direction c switches wrenching bar 6.At this time, jaw clamping face 7 and 5 axis of gear handle are determined
Angle a is gradually reduced, until six side's fasteners are clamped completely.Wrenching bar 6 is rotated further, just can be tight in six sides of firm clamping
In the case of firmware, it is implemented to lock or is loosened.After to be operated, to driving end opening direction b switches wrenching bar 6
Driving end is removed from six side's fasteners.Still separated jaw living 2 and determine jaw 1 and voluntarily closed under the action of reduction torsion spring
Close.
