Description
Technical field
The utility model relates to mechanical clamp technical field, particularly a kind of boring grab.
Background technology
In active roller gear shaft design, usually on gear shaft, multiple oilhole is bored, play the effect of lubrication, the processing of oilhole is all that what to adopt is first put special drill bushing usually, then first workpiece is fixed on the workbench of bench drill with chuck or special fixture, finally hole again, find very inconvenient like this in reality is produced, often bore hole all to want manual and again look for a little, again clamping, operate very inconvenient, affect production efficiency, and there is dismounting difficulty in existing fixture, the defects such as trouble, machining accuracy for workpiece also receives impact.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide one can improve drilling efficiency and machining accuracy, easy accessibility, boring grab rapidly.
Realize the technical solution of the utility model as follows:
A kind of boring grab, comprise clamp body, bearing, pressing plate, pull bar, eccentric sphere handle, regulate push rod, it is characterized in that: described pull bar is fixed on clamp body by nut, pull bar upper end is arranged with pressing plate, be provided with the spring of winding on pull bar between pressing plate with clamp body to be connected, pull bar side is also provided with adjustment push rod, push rod lower end is regulated to be fixed on clamp body, upper end is connected with pressing plate, adjustment push rod is also provided with the adjusting nut for supporting pressing plate, pull bar top is also provided with the eccentric sphere handle of flexible connection, bearing is connected on clamp body by head.
Described head comprises gripper shoe, slide block and guide rail, and slide block one end is fixedly connected on bottom gripper shoe, the other end is connected with slide, advantage is can by the rail moving of slide block along guide rail bottom gripper shoe, easy to use, greatly meets the demand of diverse location in operation.
Described bearing is V-structure, and advantage is convenient to support workpiece, prevents workpiece to both sides landing.
Described eccentric sphere handle is connected by connecting pin with pull bar, and advantage is that being convenient to handle carrys out back rotation on the one hand, can not be able to unclamp by clamping platen on the other hand after rotation.
Have employed above-mentioned scheme, pull bar can regulate its height by nut, regulate push rod can be regulated the height of pressing plate by adjusting nut, also play the effect supporting pressing plate simultaneously, the spring be provided with between pressing plate and clamp body can be used for spacing and push pressing plate open, eccentric sphere handle and pull bar are rotationally connected, rotating eccentricity player handle, can make pressing plate workpiece pressing, structure is simple, be applicable to the workpiece of various shape, machining accuracy is high; Bearing is fixed by screws on head, moving around of workpiece can be realized by head, greatly improve drilling efficiency, and only need realize multiple clamping by eccentric sphere handle, then can realize the step processing of multiple holes one, greatly save the time and improve efficiency, can also to send a car the workpiece of different-diameter by changing the bearing of different size in addition, applied widely, easy accessibility, improves work efficiency.
