Abstract
The invention discloses an eccentric arc-shaped lathe clamp which comprises a clamp body and clamp plates, wherein, the clamp body has a disk head and a middle cylinder; axial through holes with the diameter of D and distance a from the center of the clamp body are arranged on the disk; oblique grooves which are arranged on the outer end surfaces of the through holes are connected with the through holes, have the width of D and respectively form an Alpha angle with the disk in the radial direction; the side surface of the cylinder is provided with corresponding circular grooves; the clamp plates are arranged on the outer end surface of the disk; D, a and Alpha are the relevant sizes and angle of a workpiece. Four groups of through holes, oblique grooves and circular grooves are distributed evenly. The clamp is used for lathing the eccentric circular surface of a hook-head eccentric axle and is convenient for clamping and reliable in positioning. The clamp of the invention can improve production efficiency, lathing precision and product interchangeability and meet the lathing demand of special parts, particularly suitable for mass production.
Description
Technical field
The present invention relates to a kind of clamp for turning, especially for the eccentric arc vehicle clamper of eave tile eccentric shaft processing.
Background technology
The eave tile eccentric shaft is a part that shape is special in certain equipment, end in circular shaft has a horizontal eave tile, the circular shaft diameter is D, it is the off-centre operation cambered surface of R that there are a segment length L, radius in the middle part, this arc surface center and circular shaft centre distance are a (a＜R), and the angle of this center of arc's face and eave tile median plane is α (referring to accompanying drawing 1, an accompanying drawing 2).At present, the off-centre operation cambered surface of this part is generally processed on lathe, adds man-hour with the eccentric clamping of workpiece, need repeatedly adjust, and the examination cutter, troublesome poeration not only, efficient is low, and machining accuracy cannot say for sure card, and interchangeability is poor, is not suitable for producing in batches.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art part, provides a kind of simple in structure, convenient mounting and clamping, and working (machining) efficiency height, precision are good, the eccentric arc vehicle clamper that is used for the processing of eave tile eccentric shaft that is fit to produce in batches.
Technical scheme of the present invention is: the clamp body head of these anchor clamps is a disk, the middle part is a cylinder, have on the disk diameter be D, with clamp body centre distance be the axially extending bore of a, the disk outer face have with this through hole link to each other, width is D, median plane is the oblique slot of α with disk diameter to becoming the inclination angle, there is the coaxial line that communicates with above-mentioned through hole the cylinder side, with the deep-slotted chip breaker of radius, the disk outer face is provided with pressing plate, cylinder diameter d＜2R, above-mentioned D, a, α, R are the relative dimensions and the angle of the workpiece of clamping on these anchor clamps.
Further scheme is: described through hole, oblique slot and deep-slotted chip breaker have 4 groups, evenly distribute the oblique unanimity of each oblique slot; There is centre bore at described clamp body two ends; The flexible pad in the inboard contact workpiece place of described pressing plate.
According to above technical scheme, these anchor clamps mainly are made of clamp body and pressing plate, simple in structure, process also uncomplicatedly, during use, the circular shaft of workpiece is inserted from the through hole on the clamp body disk, extend in the deep-slotted chip breaker of cylinder side, the eave tile of workpiece is put into the oblique slot of disk end face, use pressing plate and nut (screw) to compress again, can on lathe, process the off-centre operation cambered surface of this workpiece.This anchor clamps convenient mounting and clamping is used reliably, and the machining accuracy of anchor clamps can guarantee, thereby also can improve the machining accuracy and the interchangeability of workpiece.
Adopt further technical scheme, once can process 4 workpiece, then further enhance productivity, be fit to produce in batches, and the clamp body two ends hold out against with centre bore, the flexible pad in the inboard contact workpiece place of pressing plate can further strengthen result of use.

Fig. 3 is a structural representation of the present invention;
Fig. 4 is an A-A place axial view among Fig. 3.
The specific embodiment
Referring to accompanying drawing, eave tile eccentric shaft to be processed is made of circular shaft 7 and eave tile 8, and the circular shaft diameter is D, and it is the off-centre operation cambered surface of R that there are long L, radius in the middle part, this arc surface center and circular shaft centre distance are a, and the angle of center of arc's face and eave tile median plane is α.Eccentric arc vehicle clamper of the present invention is mainly by clamp body 1, pressing plate 2 and nut 3 constitute, the clamp body head is a disk, the middle part is a cylinder, it is D that diameter is arranged on the disk, with clamp body centre distance be the axially extending bore 4 of a, the disk outer face has with this through hole and links to each other, width is D, median plane is the oblique slot 5 of α with disk diameter to becoming the inclination angle, there is the coaxial line that communicates with above-mentioned through hole the cylinder side, deep-slotted chip breaker 6 with radius, cylinder diameter d is than the little 5mm of size 2R, pressing plate 2 inboards are respectively equipped with elastomeric pad with the oblique slot corresponding site, fastening nut 3 during clamping, guarantee that pressing plate compresses 4 workpiece simultaneously.There is the centre bore through correct grinding at the two ends of clamp body 1.
Claims (4)
1. eccentric arc vehicle clamper, the clamp body head that it is characterized in that these anchor clamps is a disk, the middle part is a cylinder, have on the disk diameter be D, with clamp body centre distance be the axially extending bore of a, the disk outer face have with this through hole link to each other, width is D, median plane is the oblique slot of α with disk diameter to becoming the inclination angle, there is the coaxial line that communicates with above-mentioned through hole the cylinder side, with the deep-slotted chip breaker of radius, the disk outer face is provided with pressing plate, cylinder diameter d＜2R, above-mentioned D, a, α, R are the relative dimensions and the angle of the workpiece of clamping on these anchor clamps.
