Description
Technical field
The utility model belongs to clamping device field, and in particular to a kind of rack-and-pinion automatic centering clamp system.
Background technique
Clamping device is widely used in manufacturing field, is carrying out needing to limit the freedom of workpiece in process to part
For degree to guarantee that workpiece is in correct position, clamping device makes workpiece be in correct position by point, line, surface, therefore, clamps
Device is considered as the indispensable component of mechanical manufacturing field.
Although existing clamping device can satisfy the clamping demand of workpiece to a certain extent, process is actually used
In, positioning clamping generally carried out using scroll chuck for the centering of the round material of different-diameter, but for longer workpiece,
Or the inconvenient workpiece passed through among chuck, not very good method.
Utility model content
The purpose of the utility model is to overcome defects in the prior art, provide a kind of rack-and-pinion automatic centering clamping
Mechanism.
In order to achieve the above object, the utility model adopts the following technical solutions:
A kind of rack-and-pinion automatic centering clamp system, including pedestal, the cylinder and clamping unit of setting on the base；
The clamping unit includes sliding rail, the gear being arranged on the sliding rail, is symmetricly set on the gear
The top shoe unit and downslide module unit of upper and lower two sides and be arranged at left and right sides of the gear and respectively with the tooth
Take turns the upper rack and lower rack gear of engagement；The top shoe unit includes top shoe and the upper folder that connect with the top shoe
Tight block；The top shoe is connect with the upper rack；The sliding block is connect with the lower rack gear；The downslide
Module unit includes sliding block and the lower gripping block that connect with the sliding block；The upper clamping block include with it is described upper
The upper holder of sliding block connection and the upper grip being detachably connected with the upper holder；The lower gripping block include with it is described
Sliding block connection lower holder and the lower collet that is detachably connected with the lower holder；
The cylinder is connect by connecting plate with the top shoe.
The upper grip is equipped with the lower collet and V-shaped setting.
Preferably, the upper grip includes 2 and is separately positioned on the two sides of the upper holder lower end；
The upper rack is provided with the through-hole of inner hollow；It is provided on the sliding block and is matched with the through-hole
Upper limit position block.
The lower rack gear is provided with the through-hole of inner hollow；It is provided on the top shoe and is matched with the through-hole
Lower position block.
Compared with prior art, the utility model has the beneficial effects that
Dismountable gripping block is arranged by the self-centering of gear and rack teeth mechanism in the utility model, can be applicable in
It is clamped in different-diameter circle material, it is preferred that different-diameter circle material is clamped using V-structure, make,
Lower workpiece is convenient, and positioning accuracy is higher, and does not need for the replacement of different-diameter circle material repeatedly；The application is simultaneously in tooth
Through-hole is set in item, and limit it can during clamping by the way that matched confinement block is arranged, it will not be because of rack gear
It moves out and influences clamping effect.
