Abstract
The invention relates to a clamping and fixing method for a part blank. Firstly, a plurality of clamping points are selected on a work surface of the blank every 300-500 mm according to the shape of a part, and it is guaranteed that the positions of the clamping points are 30 mm away from the biggest outline of the horizontal plane of the part; secondly, the part blank is arranged on a worktable, threaded through holes are machined in the part blank with the clamping points as the benchmark, and the threaded through holes penetrate through the worktable; and thirdly, the part blank and the worktable are fastened together through bolts, so that the part blank is clamped and fixed. By means of the special clamping and fixing method, the extended length of a tool is reduced when the part blank is machined, the surface quality of the machined part is improved, the workload is lightened, and the production time for the part is shortened.
Description
Technical field
The invention belongs to mechanical clamping field, relate to a kind of clamping fixing means of part blank.
Background technology
Part generally all adopts traditional pressing plate to compress mode processing parts on Digit Control Machine Tool, as shown in Figure 1, the method is pressed on part blank 2 by pressing plate 1, because pressing plate 1 has certain altitude, have a strong impact on the processing mode adding part in man-hour like this, very easily cause cutter 4 and pressing plate 1 to collide, produce cutter 4 and damage.And for avoiding cutter 4 and pressing plate 1 to collide, can the tool path pattern of mandatory change cutter during numerical programming procedure, unnecessary cutter path generation will be caused like this, reduce working (machining) efficiency greatly.During processing deep-recessed part 5, for avoiding cutter head and pressing plate to collide, often lengthen cutter 4 outstanding long, platen elevation is generally at 20-30mm, and the outstanding length of corresponding cutters also just lengthens 20-30mm, but cutter is long, when processing parts 5, piece surface will produce the line that quivers, and accessory size is just difficult to ensure.
Summary of the invention
The technical problem to be solved in the present invention: when traditional part blank clamping adopts pressing plate to be fixed, to the harmful effect of cutter, and the line problem of quivering that piece surface produces.
Technical scheme of the present invention:
A clamping fixing means for part blank, is characterized in that, comprise the following steps:
The first step, according to the shape of part, blank working face chooses several clamping points every 300mm to 500mm, and the position of clamping point ensures to drop on outside the outer 30mm of the maximum appearance profile of part horizontal plane;
Second step, is positioned over part blank on workbench, with clamping point for benchmark, and machining screw through hole on part blank, tapped through hole is through in workbench;
3rd step, is tightened together part blank with workbench by bolt, and the clamping completing part blank is fixed.
Beneficial effect of the present invention: the present invention, by adopting special clamping fixed form, reduces the outstanding length that part blank adds cutter in man-hour, promotes the surface quality of processing parts, decreases workload, decrease the production time of part.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that traditional pressing plate mode clamps regulation, and wherein, 1 is pressing plate, and 2 is part blank, and 3 is cutter head, and 4 is cutter, and 5 is part.
Fig. 2 is part blank tapped through hole machining sketch chart, and wherein, 6 is drill bit, and 7 is bolt hole.
Fig. 3 is that part blank is fixedly clamped aft-loaded airfoil schematic diagram, and wherein, 8 is the soket head cap screw in dump bolt hole
Detailed description of the invention
Below in conjunction with Figure of description, installation of the present invention and working method are described.
(1) 1-2 bolt hole is bored at the former pressing plate place of blank, as shown in Figure 2
With φ 12 drill bit 6 auger shell keyhole 7, bullet base limit, hole site 15mm, be 10-30mm apart from part.
(2) bolt is screwed into part blank, as shown in Figure 3
Be screwed into by hexagon socket head cap screw 10 in the corresponding bolt hole of part blank, bolt upper surface lower than part blank upper surface, will add the feed that man-hour would not affect part like this, and cutter outstanding long 9 also can reduce 20-30mm.
