Abstract
The invention belongs to a self-centering clamping structure and the object centering and positioning field, and particularly relates to a self-centering clamping device adopting a single-point driving mode. The self-centering clamping device consists of clamping jaws fixedly arranged on ac clamp main body and capable of swinging around a shaft, rotatable pressure wheels mounted between an upper holding frame and a lower holding frame, the holding frames and a screw for applying driving force, wherein the screw passes through a fixed nut on a screw bracket and then is fixed to a ring-shaped clamp main body; one end of the screw is pressed below the rotatable pressure wheels mounted between the upper holding frame and the lower holding frame; and wedge-shaped clamping jaws capable of swinging around the shaft are further mounted on the clamp main body below the pressure wheels. According to the self-centering clamping device adopting the single-point driving mode, the four pressure wheels are driven by the holding frames to act with the four clamping jaws, and move inwards, so that clamping action is completed and self-centering can be realized, and therefore, fixing stability can be further strengthened.
Description
Technical field
The invention belongs to self-centering clamping structure and object centering positioning field, be specifically related to the self-centering clamping that a kind of single-point drives
Device.
Background technology
General object clamping generally uses multiple trip bolt modes to realize, and clamping process usually occurs eccentric on-the-spot.Using
During there is potential safety hazard, fixation body stability has certain defect, and the disassembly process of fixation body is the numbest simultaneously
Tired, waste time and energy.It is therefore desirable to redesign a kind of novel clamping structure, while realizing object clamping, it is possible to real
Existing self-centering function.
Summary of the invention
It is an object of the invention to provide the self-centering clamping structure that a kind of single-point drives, it is achieved preferably clamping effect, make to be fixed
While object stably keeps, it is possible to ensure the self-centering clamping device that the agonic single-point in center drives.
The object of the present invention is achieved like this:
The self-centering clamping device that a kind of single-point drives, by being fixed on jaw oscillatable about an axis on jig main body, being arranged on up and down
The screw rod composition of rotating pinch roller, retainer and applying driving force between two panels retainer, screw rod is by through screw bracket
On fixing nut be fixed on annular jig main body on, one end of screw rod is pressed in and is arranged on turning between upper and lower two panels retainer
The lower section of dynamic pinch roller, the jig main body below pinch roller is also equipped with the jaw oscillatable about an axis of wedge shape.
Described jaw, is four, is symmetrically mounted on jig main body.
The beneficial effects of the present invention is:
The present invention by four pinch rollers under the drive of retainer simultaneously with four jaw action, simultaneously inward, complete clamping
Action, can realize self-centering, and then more preferably strengthen fixing stability.
Accompanying drawing explanation
Fig. 1 is the self-centering clamping structure drawing of device that single-point drives.
Fig. 2 is the self-centering clamping device design sketch that single-point drives.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described further.
The self-centering clamping device that single-point drives is mainly by being fixed on jaw oscillatable about an axis on jig main body, being arranged on upper and lower two
The screw rod composition of rotating pinch roller, retainer and applying driving force between sheet retainer.During the work of this device, rotate through
Fixing the screw rod of nut on screw bracket, screw rod pulls retainer to move.The pinch roller being arranged on retainer, at the band of retainer
Under Dong, move along jig main body outer wall, swingable jaw is pressed to, inside jig main body, complete holding action.Four pressures
Take turns by the drive of retainer and four jaw action, simultaneously inward, complete holding action, it is achieved self-centering function.
Apparatus of the present invention provide the self-centering clamping structure that a kind of single-point drives, oscillatable about an axis including being fixed on jig main body
Jaw, the rotating pinch roller being arranged between upper and lower two panels retainer, retainer and applying driving force screw rod composition.This
During device work, rotating through the screw rod of fixing nut on screw bracket, screw rod pulls retainer to move.It is arranged on retainer
On pinch roller, under the drive of retainer, move along jig main body outer wall, swingable jaw pressed to inside jig main body,
Complete holding action.With four jaw action, simultaneously inward while of by four pinch rollers under the drive of retainer, complete
Holding action, can realize self-centering, and then more preferably strengthen fixing stability.
Refering to Fig. 1, apparatus of the present invention are mainly by being fixed on jaw oscillatable about an axis on jig main body, being arranged on upper and lower two panels and protect
Hold the screw rod composition of the rotating pinch roller between frame, retainer and applying driving force.During work, rotate through on screw bracket
The screw rod of fixing nut, screw rod pulls retainer to move.The pinch roller being arranged on retainer, under the drive of retainer, edge
The motion of jig main body outer wall, swingable jaw is pressed to, inside jig main body, complete holding action.Existed by four pinch rollers
With four jaw action, simultaneously inward while of under the drive of retainer, complete holding action, self-centering can be realized.
Claims (2)
