Description
Technical field
The present invention relates to hard alloy top hammer processing technique field, especially relate to a kind of clamping device of processing rigid alloy top hammer outer cone circle.
Background technology
In the synthetic industry of superhard material, hard alloy top hammer is by the critical piece of the high pressure high temperature device of static pressure method synthesis of artificial diamond, makes because it adopts carbide alloy, possesses high strength, good wearability, toughness and heat endurance.As shown in the structural representation of top hammer that Figure 20 forms by a firing product, top hammer comprises little truncated rectangular pyramids body 1, large truncated rectangular pyramids body 2 and inverted cone 3, the top of top hammer is little truncated rectangular pyramids body 1, the end face 6 of little truncated rectangular pyramids body 1 is square, the side of little truncated rectangular pyramids body 1 is four one deck tangent planes 4, and little truncated rectangular pyramids body 1 bottom is connected with large truncated rectangular pyramids body 2, and the side of large truncated rectangular pyramids body 2 is four two layers of tangent planes 5, the bottom of large truncated rectangular pyramids body 2 is connected with inverted cone 3, and one deck tangent plane 4 is not less than the inclination angle of two layers of tangent plane 5.The top hammer that forms by a firing product need be compressing through powder former, then make by sintering, the product that form by a firing also have situation about deforming, because the molding surface size precision prescribed to top hammer is high, so usually need to carry out follow-up a certain amount of metal cutting processing.At the outer cone bowlder of processing top hammer, owing to cannot normally adopting scroll chuck to position clamping, and the top hammer that forms by a firing product has profile out-of-flatness, slightly the defect such as inclination exists, therefore take into account the stability of considering the reliable clamping in location and guaranteeing to add man-hour, need to utilize profiling fixture, just can make top hammer in process, keep stable rotation, eliminate and produce displacement, loosening phenomenon.
Summary of the invention
The present invention is directed to the deficiency of existing positioning and clamping technology, technical problem to be solved is to provide a kind of clamping device of processing rigid alloy top hammer outer cone circle, it utilizes profiling fixture, can carry out clamping location accurately and reliably, make the top hammer in process keep stable rotation, avoid displacement, loosening phenomenon to occur.
The present invention makes above-mentioned technical problem be solved by the following technical programs.
A clamping device for processing rigid alloy top hammer outer cone circle, comprises chuck, cruciform joint, left top chuck and right top board, be arranged at intervals with and be mutually four grip blocks that 90 degree are circumferential symmetry at the right-hand member of left top chuck, two layers of tangent plane setting bonded to each other of the inclined-plane, inner side of grip block and top hammer, the interstitial structure keeping between grip block forms observes groove, the end on inclined-plane, inner side extends to form accommodating cavity with the level inclination that is not more than inclined-plane, inner side towards the bottom of grip block, accommodating cavity can hold the little truncated rectangular pyramids body of top hammer and keep matched in clearance, be provided with the first dovetail projection at the left end of left top chuck, the right-hand member of cruciform joint is provided with the first dovetail groove, between the first dovetail projection and the first dovetail groove, be provided with the first positioning regulating mechanism, what the first dovetail projection can radially slide by the first positioning regulating mechanism is connected on the first dovetail groove, the sliding trace of the first dovetail projection becomes 45 degree inclination angles with horizontal axis, be provided with the second dovetail projection at the left end of cruciform joint, the right-hand member of chuck is provided with the second dovetail groove, between the second dovetail projection and the second dovetail groove, be provided with the second positioning regulating mechanism, what the second dovetail projection can radially slide by the second positioning regulating mechanism is connected on the second dovetail groove, and the sliding trace of the second dovetail projection becomes 90 degree right angles with the sliding trace of the first dovetail projection, the end face that the cone bottom surface of the left end setting of right top board and the inverted cone of top hammer fits, the right-hand member of right top board arranges centre bore.
