Description

A kind of eccentric wheel pressing plate clamping structure
Technical field
The present invention relates to a kind of frock clamp, particularly relate to a kind of eccentric wheel pressing plate clamping structure.
Background technology
The required frock clamp power source of small lot automobile making is manually.Manually clamp be in the clamping device the most simply, the most original form.It has following advantage: 1. power resources can not receive the restriction of workshop appliance condition, and simple structure is easy to maintenance.2. the operator can change the size of clamping force within the specific limits according to actual needs, thereby obtains only clamping force.But also there are some shortcomings in hand actuable clamping device.Like the manual structure of the most often using at present is that the shortcoming of manual spiral binding clasp and hand lever hinge binding clasp is: and manual spiral binding clasp clamping force is less than normal<and 300N and spiral revolution stroke are less, slow in one's movements, and efficient is lower.Hand lever hinge binding clasp is realized the self-locking difficulty and takes up room greatly that manufacturing cost is high.
Summary of the invention
The present invention accomplishes in order to solve deficiency of the prior art, the purpose of this invention is to provide a kind of simple structure, and easy to operate, clamping force is big and have an eccentric wheel pressing plate clamping structure of auto-lock function.
Technical scheme of the present invention is:
A kind of eccentric wheel pressing plate clamping structure; Comprise connecting plate, be positioned at pressing plate, flap, the guiding mechanism of said connecting plate top and be fixed on the eccentric wheel on the end of said connecting plate; Said eccentric wheel and said guiding mechanism are positioned at the homonymy of said connecting plate, it is characterized in that:
There is the groove that runs through said thickness of compressive plate at the middle part of said pressing plate;
Said flap is the H type, and the top of said connecting plate snaps in the bottom slot of said flap, and said flap is fixedly connected with said connecting plate; The bearing pin of the said groove of the top of said flap through passing said pressing plate is connected with said pressing plate; Said bearing pin can the trajectory of the shape of the said groove in edge move in said groove;
Said guiding mechanism comprises that from top to bottom first is fixedly connected piece, the second fixed connection piece, adjustment bolt and power transmission bolt;
Said first fixed block is the L type, on one side it is fixed on the end of said pressing plate, its another side extends to the direction perpendicular to said pressing plate; Said adjustment bolt passes the another side of said first fixed block from bottom to top and through the adjustment nut it is fixedly connected with said first fixed block;
Said second fixed block is a sheet, is fixed on the said connecting plate perpendicular to said connecting plate, and extends setting with the another side of said first fixed block towards identical direction;
Said power transmission bolt pass from bottom to top said second fixed block and through be arranged on said second be fixedly connected the upper surface of piece the power transmission nut it is fixedly connected with said second fixed block; The outer sheathed spring of said power transmission bolt; Said spring is positioned at said second and is fixedly connected under the piece;
Said power transmission bolt and coaxial with said adjustment bolt center;
The bottom of said adjustment bolt is withstood on the top of said power transmission bolt from bottom to top; The bottom of said power transmission bolt and said eccentric wheel outer surface are tangent;
The other end of said pressing plate slightly is bent to form the L type downwards, and clamping element is between the end away from said guiding mechanism of said connecting plate and said pressing plate.
Technical scheme of the present invention can also be:
Said groove is along the bearing of trend setting of pressing plate, and its end bending slightly downwards near said first fixed connecting plate extends to form the L type, so said groove is made up of vertical slots that is linked in sequence and level trough; The vertical slots of said groove and the interface point of level trough flex point for clamping and getting loose.
When being positioned at the level trough of said groove, realizes said bearing pin getting loose of clamping structure; When being positioned at the vertical portion of said groove, realizes said bearing pin the locking of clamping structure.
Said eccentric wheel is fixed on the said connecting plate through set bolt.
Said eccentric wheel is provided with handle; The said handle eccentric wheel that moves in the direction of the clock; The eccentric wheel tangent with it power transmission bolt of jack-up that makes progress; The adjustment bolt that power transmission bolt jack-up contacts with it; The adjustment bolt receives after the power upwards because of the locking effect of groove to bearing pin, makes pressing plate turn clockwise around said bearing pin, and the other end of said pressing plate compresses clamping element downwards; When handle rotates eccentric wheel by counter clockwise direction gently; Eccentric wheel drives the power transmission bolt and moves down; The adjustment bolt also along with the power transmission bolt toward moving down, bearing pin gets loose from flex point, and along the trajectory of the level trough of groove to a end motion away from flex point; This moment, pressing plate and clamping element broke away from, and workpiece can freely take out.
Said guiding mechanism compensates the loss that the eccentric wheel working face causes because of wearing and tearing through the decrement of adjustment spring and the length of adjustment adjustment bolt.
Eccentric wheel pressing plate clamping structure of the present invention has the following advantages:
1, meet " low cost " manufacturing philosophy, utilize leftover bits can accomplish the manufacturing of all parts, low cost of manufacture, and reusable; Simple to operate, firmly can realize unidirectional clamping gently to handle, and pressing plate length<200mm, do not take up room;
2, eccentric wheel handle has suitable operating position, and is simple to operation, only needs gently that turning handle just can produce>clamping force of 300N;
3, adopt along the direct clamping work pieces of structure of the track location of groove and have auto-lock function;
4, have guiding mechanism, the wearing and tearing of eccentric wheel working face can regularly compensate through the adjustment bolt.
