Abstract
The utility model provides a two-claw eccentric floating clamp for machining an automobile engine piston eccentric combustion chamber, relating to a clamp used together with a numerical control machine tool. The clamp is provided with two claw power chucks, the surfaces of the inner sides of the two claws, which are used for clamping a workpiece, are machined to eccentric arc surfaces, one of the two claws is made into a floating claw to compensate the error of the workpiece, the floating claw is composed of a floating matrix and a floating pawl, the floating pawl is arranged on the floating matrix via a rotary pin and a bolt, and the oscillating quantity of the floating pawl is defined by a position-specified pin, a rhombic pin is arranged on the inner side of the floating matrix to realize the angle positioning of the pin hole of the workpiece to be machined and the eccentricity, an end face positioning block is arranged, and in order to overcome the unbalanced rotation caused by the eccentricity, arc-shaped de-weight grooves are milled at the bottoms of the chuck bodies to remove the larger unbalance, and a plurality of screw holes are arranged in the end faces of the chucks to realize the microscale adjustment. By using such a clamp, the automatic installing and clamping as well as the machining of workpieces can be realized on the numerical control machine tool.
Description
Technical field
Two pawls eccentric floating clamp in the eccentric combustion chamber of a kind of processing automobile engine piston relates to a kind of and the matching used anchor clamps of Digit Control Machine Tool.
Background technology
The traditional diamond-making technique of the eccentric combustion chamber of piston is to utilize manual two-jaw self-centering chuck, at chuck body end face configuration fixed locating stud, manually goes up workpiece, align alignment pin, manually clamping work pieces because clamping is chronic, causes this operation processing beat to be thirty minutes long.
The utility model content
The purpose of this utility model provides a kind of anchor clamps that can realize processing automatically the eccentric combustion chamber of engine piston.
The eccentric combustion chamber of this processing automobile engine piston eccentric floating clamp of two pawls adopts two claw power chucks, and the face of the inboard folder workpiece of two claws is processed into eccentric garden cambered surface; Make unsteady claw for one in two claws, with the error of compensation workpiece, namely this claw partly is made of buoyant body and unsteady pawl two, and the pawl that floats is contained on the buoyant body by fulcrum post and bolt, and by the float oscillating quantity of pawl of position-limitting pin restriction; In the buoyant body inboard rhombus pin is housed, locatees to realize to be processed pin-and-hole and eccentric angle; End face at disk body is equipped with the end face locating piece; In order to overcome the rotation imbalance that is caused by off-centre, mill arc in the bottom of chuck body and remove heavy groove, to remove bigger amount of unbalance, the end face at chuck has some screw holes to realize the trace adjusting again.
During work, the eccentric combustion chamber of this processing automobile engine piston eccentric floating clamp of two pawls is contained on the Digit Control Machine Tool, can controls the switching of two claws by the oil cylinder on the Digit Control Machine Tool.Be contained between two claws by manipulator dress workpiece, rhombus pin realization angle location, locating piece is realized end to the location, eccentric realization is to lean on the off-centre of claw to realize.Use these anchor clamps, can utilize the C s function of spindle of numerical control lathe, the accurate position of correcting rhombus pin and workpiece pin-and-hole, workpiece on the manipulator clamps by power and clamps, and clamping is reliable rapidly, and the processing beat is 60 seconds.

The specific embodiment
The eccentric combustion chamber of this processing automobile engine piston eccentric floating clamp of two pawls adopts the face of the inboard folder workpiece 2 of two claw power chucks, 8, two claws 1 to be processed into eccentric garden cambered surface; Make unsteady claw for one in two claws 1, with the error of compensation workpiece, namely this claw is made of buoyant body 6 and 5 liang of parts of unsteady pawl, and the pawl 5 that floats is contained on the buoyant body 6 by fulcrum post 4 and bolt, and by the float oscillating quantity of pawl of position-limitting pin 10 restrictions; In buoyant body 6 inboards rhombus pin 3 is housed, locatees to realize to be processed 2 pin-and-holes and eccentric angle; End face at disk body is equipped with end face locating piece 7; In order to overcome the rotation imbalance that is caused by off-centre, mill arc in the bottom of chuck body and remove heavy groove, to remove bigger amount of unbalance, the end face at chuck 8 has some screw holes 9 to realize the trace adjusting again.
Claims (2)
