Abstract
A feeding device is installed on a machine and is utilized to convey a workpiece to be machined. The feeding device includes first and second feeding apparatus and in conveying the workpiece the workpiece has two lateral sides engaged by the first and second feeding apparatuses respectively. A clamping device is installed on the machine and is utilized to hold the moving workpiece. The clamping device includes first clamping mechanism including first and second clamping apparatuses and a second clamping mechanism including a third clamping apparatus, with the first and second clamping device holding the lateral sides of the workpiece and with the third clamping apparatus holding the top side of the workpiece.
Claims10
A device for feeding and clamping a workpiece comprising:
- a feeding device including first and second feeding apparatuses disposed opposite one another, with each of the first and second feeding apparatuses including a rolling member with ridges, and with the second feeding apparatus operably moveable toward and away from the first feeding apparatus;
- and
- a clamping device including first and second clamping mechanisms, with the first clamping mechanism including first and second clamping apparatuses disposed opposite to each other, with the first and second clamping apparatuses including first and second engaging sections respectively, and with the second clamping apparatus operably moveable toward and away from the first clamping apparatus, with the second clamping mechanism including a third clamping apparatus operably moveable upwardly and downwardly, and with the third clamping apparatus including a third engaging section;
- and
- wherein when the device feeds the workpiece the rolling members of the associated first and second feeding apparatuses are adapted to be in frictional engagement with two opposite lateral sides of the workpiece;
- and the first and second engaging sections of the associated first and second clamping apparatuses are adapted to be in engagement with the two lateral sides of the workpiece;
- and the third engaging section of the third clamping apparatus is adapted to be in engagement with a top side of the workpiece;
- and
- a moveable lifting device including a first body retained at a first position and a buffering apparatus including a first end connected to the first body and a second end connected to the third clamping apparatus, with the buffering apparatus being increased in length to react against a weight of the third clamping apparatus.
