Description
Technical field
The present invention relates to the nickel-based alloy sample clamping mechanism that surface grinding machine is special, specifically refer to, be mainly used to processing thickness and process at the surfacing of the nickel-base alloy plate of 25 ~ 40mm.Belong to nickel-based alloy sample Grinding Technology field.
Background technology
High accuracy nickel-base alloy plate is a kind of sample kind being widely used in testing of materials field.Because of its material has cannot magnetized physical characteristic, electromagnetic platen directly cannot be used to adsorb and to carry out processing operation, at present, it is fixing that the industry adopts rosin adhesive method to implement sample mostly, but the method is clamping poor stability not only, in to the grinding process of sample, easily cause specimen surface to occur fish-scale shape ripple because of gap chatter, have a strong impact on grinding quality; And the binding agent residue on sample is difficult to remove, while having a strong impact on processing usefulness, chemical attack is caused to platen surface.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of surface grinding machine special nickel-based alloy sample clamping mechanism, can stable holding sample, prevents the fish-scale shape ripple occurred because of the gap flutter in grinding process, promotes grinding quality.
The technical scheme that the present invention solves the problem is as follows:
The special nickel-based alloy sample clamping mechanism of a kind of surface grinding machine, comprises pedestal, described pedestal sets firmly workbench, it is characterized in that:
Described pedestal is connected with bearing block and the slide rail being positioned at bearing block both sides, described bearing block is provided with driving adjusting part, described slide rail is provided with can along the clamping assembly of slide rail translation;
Described driving adjusting part comprises the bearing group of holding in bearing block shoulder hole and screw rod, described screw rod is multidiameter structure, the two ends of screw rod are protruding through the inner ring of bearing group, the front end of screw rod has draw-in groove, the outer jump ring of bearing is installed in described draw-in groove, the inner ring of bearing group is arranged on bearing outward between jump ring and the screw rod shaft shoulder, the two ends of bearing block are provided with the fore bearing transparent cover and rear bearing transparent cover that contact with bearing group outer ring, and the outer jump ring of bearing is between bearing group inner ring and fore bearing transparent cover;
Described clamping assembly comprises slide, in the middle part of slide, swivel nut is installed, described swivel nut matches with screw rod, described slide has the through hole being parallel to sliding sleeve axis, described through hole is built with compression bar, and the front end of compression bar is scarf, rear end is stretched out outside slide, slide is provided with and presses down screw, and the lower end pressing down screw sets firmly pressure ball, and described pressure ball contacts with scarf;
Described workbench is connected with cross benchmark.
Adopt above-mentioned clamping mechanism with when carrying out grinding to nickel-based alloy sample, sample is placed on the table, two sides are against cross benchmark, rotating screw bolt subsequently, drives slide translation, the another side of compression bar and sample plate is contacted, finally use hexagonal spiral shell rod to regulate and press down screw, until the side of workpiece is tightly withstood on compression bar top, complete clamping, start grinding.The pressure ball that the lower end pressing down screw sets firmly can utilize mechanical self-latching characteristic effectively to prevent the transverse direction stepping up state moulded rod from falling back.
Further, preferably, described bearing group comprises the front deep groove ball bearing, thrust ball bearing and the rear deep groove ball bearing that are arranged in order, is separately installed with bearing space ring between described front deep groove ball bearing and thrust ball bearing and between thrust ball bearing and rear deep groove ball bearing.This cooperation can increase the axial thrust of bearing, prevents sample work in-process from occurring play and occurring fish scale-shaped, and the transmission stability of screw rod can be made stronger.
Further improving is slide has two through holes, and these two through holes are symmetricly set on slide both sides, are all provided with compression bar in through hole, slide has two and corresponding with compression bar presses down screw.It is fixing spacing that such bilateral regulates compression bar can realize two symmetric points in sample side, can implement more firm spacing fixing, also facilitate spacing to the Multi-contact of lateral plane degree lower sample plate simultaneously to sample.
Further again, described compression bar shaft offers keyway vertically, and slide is provided with the anti-transfer screw in the nested keyway in lower end.Can effectively prevent compression bar from sliding process, rotation occurring.
Further, described workbench is installed in the middle part of pedestal, and pedestal and workbench form " convex " font, and the both sides of pedestal have driving adjusting part and clamping assembly respectively.Effectively can utilize workbench like this, improve working (machining) efficiency.
Further, every two covers of installing side by side of described pedestal drive adjusting part and clamping assembly.Such workbench can carry out the processing operation of 4 samples simultaneously, and working (machining) efficiency is further enhanced.
Described cross benchmark both sides offer inclination angle, and notch is offered on the both sides of root, and described workbench offers the groove matched with cross benchmark root.Offer inclination angle and while raising contact precision, in grinding process, component can be pressed down for workpiece provides, strengthen processing stability.The notch of benchmark root, effectively can eliminate plate edge burr and have an impact to limit accuracy.
Further, described slide two side bottom offers groove, described slide rail shape and groove suitable.
As preferably, the length of this clamping mechanism institute processing sample is 150mm.
To sum up, compared with prior art, beneficial effect of the present invention is:
1, clamping stability of the present invention is strong, avoids existing clamping method in the grinding process of sample completely because fish-scale shape ripple appears in gap chatter specimen surface, substantially increases grinding quality.
2, the present invention can realize realizing on common plane grinding machine to 2 of the lower plate of lateral plane degree or Multi-contact spacing.
3, the present invention coordinates cross-based to process 4 nickel-based alloy samples simultaneously, effectively will definitely can utilize workbench like this on pedestal, improves working (machining) efficiency.
