Summary of the invention

To above problem; The utility model provides a kind of grip device that is used for inlet manifold boring, tapping processing; It can effectively improve location, the clamping precision of workpiece, thereby guarantees the workpiece machining accuracy, and can reduce labor strength greatly, enhances productivity, reduces production costs.

Its technical scheme is such; It comprises base plate; It is characterized in that: it also comprises workpiece location-plate, clamp device and bushing plate energetically, and said workpiece location-plate vertically is installed on the said base plate, and said clamp device energetically is installed on said base plate through cushion block and over against the locating surface of said workpiece location-plate; Said bushing plate is connected with the upper end of said workpiece location-plate through hinge, and the bore position correspondence of treating according to workpiece on the said bushing plate is installed drill bushing.

It is further characterized in that: gripper shoe and alignment pin are installed on the locating surface of said workpiece location-plate, and said gripper shoe is provided with upper and lower two rows, and the position of said alignment pin is provided with according to the workpiece benchmark; Said drill bushing is fixed in said bushing plate through the drill bushing screw; Support column also is installed on the said base plate, and tapping adds man-hour when holing perhaps, and said bushing plate is connected fixing with said support column through lock-screw.

Adopt the utility model grip device to inlet manifold hole, tapping processing; Its beneficial effect is: its through the gripper shoe on the locating surface of workpiece location-plate with alignment pin location workpiece, simultaneously pass through energetically clamp device with Work-sheet pressing on the locating surface of workpiece location-plate; Guarantee the reliable location and the clamping of workpiece, improved machining accuracy; Simultaneously, the bushing plate that drill bushing is installed is connected with the upper end of workpiece location-plate through hinge, and the folding of bushing plate is easy to operate, effectively reduces labor strength, enhances productivity; And the position of drill bushing is provided with according to the position of workpiece design boring or tapping, can further guarantee to hole or the precision of tapping position, thereby further guarantee the machining accuracy of workpiece; In addition, tapping adds man-hour when holing perhaps, and bushing plate and support column are locked through lock-screw, have guaranteed that boring or tapping add the stability of anchor clamps in man-hour, further guarantee the reliable positioning and clamping and the machining accuracy of workpiece; To the boring or the tapping of inlet manifold different-diameter, the utility model clamping tool only need be changed corresponding drill bushing on request and get final product; And to the different inlet manifold of bore position or tapping position, also only need to change corresponding bushing plate to get final product, its highly versatile, applied widely, can play the effect that reduces production costs.。
