Description
Technical field
The utility model belongs to crankshaft production machine apparatus field, is specifically related to a kind of vuilt-up crankshaft heavy boring eccentric hole clamp.
Background technology
To be exactly cylindrical and the cylindrical of part or cylindrical parallel with the axis of endoporus and do not coincide for eccentric element, the part of deviation certain distance.Eccentric element is applied very extensive in plant equipment, and in machine driving, gyration becomes linear reciprocating motion or linear reciprocating motion becomes gyration, generally all utilizes eccentric element to complete.As the lubricating pump that eccentric work piece for headstock case drives, the bent axle in automobile engine, the bent axle of lumbering equipment etc., but the processing technology of eccentric element relatively check, subject matter is the more difficult eccentric throw of getting hold of, precision is high, difficulty reaches corresponding tolerance.
Eccentric crankshaft is all generally to process on lathe, and their process principle is basic identical; Be mainly to take measures aspect clamping, the axis centering of the eccentric part of needs being processed is to coinciding with lathe spindle rotation.In conventional art, the machining accuracy of bent axle is not high enough, does not adapt to high-accuracy mechanical equipment, moreover working (machining) efficiency is low.
In view of this, the inventor provides a kind of vuilt-up crankshaft keyseat air-actuated jaw, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of vuilt-up crankshaft heavy boring eccentric hole clamp, and to solve in conventional art, the precision of the processing of bent axle is not high enough, does not adapt to high-accuracy mechanical equipment.
For above-mentioned technical problem, technical solutions of the utility model are as follows: a kind of vuilt-up crankshaft heavy boring eccentric hole clamp, this eccentric hole clamp adds the corresponding setting of hole boring cutter with machine, comprise pull bar, one end of pull bar is installed with a tension piston, the other end of pull bar is provided with cylinder, and this cylinder can drive tension piston displacement; On described tension piston, be installed with chuck body, be positioned at chuck body one end face and be provided with a lock chamber, this lock chamber extends in pull bar piston to pull bar direction; Described chuck body one end face is provided with a wedge-caulking device, and this wedge-caulking device is positioned at lock chamber top; It is corresponding that described chuck body one end face and machine add hole boring cutter.
Further, described chuck body comprises that the machine tool chief axis being connected and fixed successively by standing screw connects dish, fixture and main shaft and connects dish, fastening board adapter sleeve and centering plate.
The beneficial effects of the utility model: the utility model is by be strained and fixed one end of workpiece of tension piston, and the other end of workpiece clamps by wedge-caulking device, so, can fix tight target workpiece, makes the eccentric orfice processing precise of workpiece.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation; Fig. 2 is the right view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, what the utility model disclosed is a kind of vuilt-up crankshaft heavy boring eccentric hole clamp, this eccentric hole clamp adds the corresponding setting of hole boring cutter 7 with machine, comprise pull bar 1, one end of pull bar 1 is installed with a tension piston 2, the other end of pull bar 1 is provided with cylinder 3, and this cylinder 3 can drive 2 displacements of tension piston; On described tension piston 2, be installed with chuck body 4, be positioned at chuck body 4 one end faces and be provided with a lock chamber 5, this lock chamber 5 extends in pull bar piston 2 to pull bar 1 direction; Described chuck body 4 one end faces are provided with a wedge-caulking device 6, and this wedge-caulking device 6 is positioned at lock chamber 5 tops; It is corresponding that described chuck body 4 one end faces and machine add hole boring cutter 7.
Further, described chuck body 4 comprises that the machine tool chief axis being connected and fixed successively by standing screw 8 connects dish 41, fixture and main shaft and connects dish 42, fastening board adapter sleeve 43 and centering plate 44.
Shown in Fig. 2, wherein, wedge-caulking device 6 comprises wedging slide plate 61, on wedging slide plate 61, square profile has four hex bolts 62, one side of wedging slide plate 61 is provided with an adjusting device 63, and this adjusting device 63 comprises adjusting screw(rod) 631, and adjusting screw(rod) 631 is provided with adjusting nut 632, adjacent adjusting nut 632 is also provided with backer's adjusting seat 633, is positioned at equally on adjusting screw(rod) 631.
The utility model operation principle: workpiece 7 is fixed on to lock chamber 5, and cylinder 3 drives the opposite direction displacement tension workpiece 7 of tension piston 2 to workpiece 7, then by wedge-caulking device 6, workpiece 7 is clamped, and so completes workpiece 7 fixing.
The utility model adopts wedge-caulking device clamping work pieces, can guarantee work spindle and eccentric throw ± 0.03 of eccentric ratio axis hole and the requirement of 100: 0.03 of the depth of parallelism of main shaft, be contained on two main axle machine tools and once can process one within the 5-6 time of second, there is efficiency high, the function that quality is steady.Than the lathe of transmission, the efficiency of inner circle mill fine grinding endoporus improves output 5-6 accompanies, and dimensional stability reaches 99.8%.Production cost and artificial quantity are significantly reduced.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
