Set, keeping set top the week side of boss to be evenly equipped with, be provided with the notch that multiple insertions keep set outboard sidewalls, the notch can opposed slot
The clamping column of the radially inner and outer movement of opening's edge, the convex wheel case for rotating cooperation is arranged with positioned at holding set top peripheral, is clamped
Post is fitted with convex wheel case inwall, and convex wheel case inner webs are provided with inwardly protruded slope with each notch corresponding position, tiltedly
Slope slope height increase along clockwise direction；Also include being arranged on below convex wheel case and pull convex wheel case counterclockwise to rotate
Torsion spring.
Further, screw thread bore is offered on the base, the holding set bottom is provided with external screw thread and and screw thread
Bore threaded；Set bottom is kept also to be connected with the locking nut for heading on base upper side, the torsion spring is arranged at locking screw
Between female and convex wheel case.
Further, packing ring is also folded between locking nut and convex wheel case, torsion spring is located at packing ring periphery；Convex wheel case
Sidepiece is also associated with handle, and cam ring set upper side Middle face, which has to cover, is keeping the cover plate on set, and cover plate is existed by screw solid lock
Cam ring is put.
Further, one end both sides are provided with the spacing block set for preventing clamping column from departing from notch to notch inwardly, keep set outer
Side wall offers the resigning annular groove stretched into for slope.
Compared with prior art, the utility model has the advantages that：The utility model can increase clamping force automatically
Drilling clamp structure it is novel, it is reasonable in design, it is simple to operate, as cutting force increases, clamping force of the clamping column to workpiece
Also with increase, prevent workpiece from loosening, it is ensured that machining accuracy.
For the purpose of this utility model, technical scheme and advantage is more clearly understood, specific embodiment will be passed through below
And relevant drawings, the utility model is described in further detail.

Embodiment
It is a kind of to increase the drilling clamp of clamping force automatically as shown in Fig. 1 ~ 3, including the bottom being installed on Drilling machines bench
Holding set 2 is installed on seat 1, the base 1, keeps 2 top the week side of boss of set to be evenly equipped with the groove that multiple insertions keep set outboard sidewalls
Mouthfuls 3, be provided with the notch 3 can the relative radially inside and outside movement of notch 3 clamping column 4, clamping column 4 and notch two side it
Between leave gap, rotate the convex wheel case 5 of cooperation positioned at keeping 2 top peripherals of set to be arranged with, clamping column 1 and convex wheel case
2 inwalls are fitted, and convex wheel case inner webs and each corresponding position of notch 3 are provided with inwardly protruded slope 6, and slope 6 is along up time
The height increase of pin direction slope；Also include the torsion spring for being arranged on the lower section of convex wheel case 5 and pulling convex wheel case 5 counterclockwise to rotate
7, torsion spring 7 needs to apply when mounted answers torsion in advance.
Torsion spring 7 pulls convex wheel case to rotate clockwise, and passes through the inside top pressure clamping column in slope and then clamping workpiece 15, workpiece
It is cylinder or polygon, it is necessary to the workpiece 15 drilled is clamped by several clamping columns to be clamped position that post clamps, convex
The slope of wheel case madial wall inwardly heads on clamping column to clamp workpiece 15；Drill bit is to rotate forward in drilling（It is i.e. square clockwise
To rotation）, drill bit to workpiece 15 when carrying out drilling, and circumferential cutting force can make clamping column produce the slope height increase to slope
The trend of direction motion, and then increase the clamping force for inwardly clamping workpiece, reach that drill thrust is bigger, the bigger purpose of clamping force.
In the present embodiment, screw thread bore 8 is offered on the base 1, it is described to keep 2 bottoms of set to be provided with external screw thread simultaneously
With the threaded of screw thread bore 8；Set bottom is kept also to be connected with the locking nut 9 for heading on base upper side, the torsion spring 7 is set
Between locking nut 9 and convex wheel case 5.
In the present embodiment, there is the upper end of clamping column 9 radian to be installed in order to workpiece underthrust, and clamping column and convex wheel case are needed
Heat-treatment quenching is wanted to improve durability.
In the present embodiment, packing ring 10 is also folded between locking nut 9 and convex wheel case 5, torsion spring position 7 is in outside packing ring 10
Enclose；The sidepiece of convex wheel case 5, which is also associated with having in the middle part of handle 11, the upper surface of convex wheel case 5 covering, is keeping the cover plate 12 on set, lid
Plate 12 on interior cam sleeve 5, controls clamping column to unclamp by screw solid lock by rotating clockwise handle 11.
In the present embodiment, one end both sides are provided with the spacing block set 13 for preventing clamping column 1 from departing from notch to notch 3 inwardly,
Keep set lateral wall to offer the resigning annular groove 14 stretched into for slope, resigning annular groove 14 can avoid keeping set and slope it
Between interfere.
Above-listed preferred embodiment, the purpose of this utility model, technical scheme and advantage are further described,
