Description
Technical field
The utility model relates to crankshaft turning manufacture field, and specifically, the utility model relates to a kind of for the eccentric turning attachment of machining crankshafts.
Background technology
Containing eccentric wheel structure in the bent axle used in compressor of air conditioner, general eccentric wheel structure by lathe turning out, in existing turning technology, directly workpiece to be processed being fixed on three grabs on chuck, then cuts with lathe tool, changes lathe tool position car that is axial and footpath phase and goes out eccentric structure, the eccentric wheel dimensional accuracy that this processing method working (machining) efficiency is low, turning goes out is low, and operation is many and loaded down with trivial details, need skilled human users, processing cost is high.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of high efficiency, the eccentric turning attachment of high accuracy machining crankshafts.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of for the eccentric turning attachment of machining crankshafts, comprise base, end cap and connecting screw, described base and end cap are joined merga pass connecting screw and are connected, also comprise front pushing cylinder and Gripper body, described Gripper body is placed in front pushing cylinder, and front pushing cylinder is placed in base, one end end face of described Gripper body is provided with eccentric orfice, uniform groove around eccentric orfice.
Described base bottom is provided with set screw, and described Gripper body inside is hollow, and Gripper body center outer surface is provided with chute, and the chamber wall that set screw runs through base cavity is inserted in chute.
The conical surface of described Gripper body is provided with locating slot, and alignment pin is inserted in corresponding locating slot position to front pushing cylinder, and alignment pin coordinates with locating slot.
Uniform anti-slip tank around described eccentric orfice.
Be provided with to rub between the cone of described Gripper body and eccentric orfice and cut avoiding hollow groove.
Adopt the technical solution of the utility model, following beneficial effect can be obtained:
Lathe dog of the present utility model, solve before grabbed the low precision of chuck car eccentric wheel structure efficiency not high drawback with three, due to three grab chuck self structure reason cannot ensure offset stablizing, offset size cannot be stablized, and debugs also more complicated.Workpiece only need be fixed on chuck by the utility model, and because chuck itself has eccentric structure, so do not need the position changing lathe tool can process qualified crankshaft eccentric wheel product, simultaneous manufacturing precision is high, efficiency is high.Gripper body is dismountable in addition, convenient with changing different sizes or model like this, also with changing other forms of chuck, can have good versatility, saving production cost.

Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operation principle etc. of detailed description of the invention of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
As shown in Fig. 2 ~ 5, turning attachment of the present utility model forms primarily of base 1, end cap 2, Gripper body 3, front pushing cylinder 4 and connecting screw 7 and set screw 5, Gripper body 3 is placed in front pushing cylinder 4, and front pushing cylinder 4 is placed in base 1, and base 1 and end cap 2 are joined merga pass connecting screw 7 and be connected.As shown in Figure 3, during work, crankshaft workpiece 8 is arranged in eccentric orfice 63, because Gripper body 3 itself is with eccentric orfice 63, so only need rotating base 1 to cut out an eccentric wheel with regard to automatic vehicle when turning eccentric wheel 82.The conical surface of Gripper body 3 is provided with locating slot 61, front pushing cylinder 4 is provided with alignment pin 6, the barrel that alignment pin 6 runs through front pushing cylinder 4 is inserted in locating slot 61, there is the positioning action of alignment pin 6 like this, clamper main body 3 can only horizontally slip along locating slot 61, thus prevents Gripper body to rotate in front pushing cylinder 4 or roll and cause location inaccurate, and set screw 5 is similar to the above with coordinating of chute 9, set screw 5 can horizontally slip in chute 9, coordinates loosening and tightening up of Gripper body 3.
As shown in Figure 6, be the structural representation of crankshaft workpiece 8, grab owing to adopting tradition three as shown in Figure 1 in the processing that the special construction of crankshaft workpiece 8 is former that chuck clamping work pieces process operation is many, low precision.Adopt this fixture to add first to be installed on lathe spindle by base installing hole 11 by base 1 man-hour, then oil cylinder pull bar is connected to pull bar installation portion 12, pull bar drives joint body 3 side-to-side movement, makes crankshaft workpiece 8 clamp and loosen.Need both can upper axle 81 was arranged in eccentric orfice 63 according to turning during turning, also can lower shaft 83 be arranged in eccentric orfice 63, then turning eccentric wheel 82, according to the Gripper body 3 needing replacing different size of eccentric size, the anti-slip tank 62 that eccentric orfice 63 surrounding is arranged plays the effect increasing piece-holder frictional force.Pull bar clamps crankshaft workpiece 8 to Zola, pushes away to the right and loosens crankshaft workpiece 8, and the conical surface of Gripper body 3 is provided with to rub cuts avoiding hollow groove 10, and when preventing turning, lathe tool hurts Gripper body 3.Gripper body 3 and front pushing cylinder 4 are all dismountable, achieve the versatility of fixture like this, only need change dissimilar chuck and can realize other processing purposes when processing other workpiece.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
