Abstract
The utility model discloses a special clamp for shaft ring clamping and belongs to the field of lathe clamps. The special clamp comprises a clamp base, a sliding track, an adjusting screw rod, a moving block and a clamping block. The lower end of the sliding track is arranged on the clamp base. The upper end of the sliding track is clamped on a concave edge at the lower end of the moving block. The lower end of the clamping block is pressed on the upper end concave edge of the moving block. The adjusting screw rod is meshed with the moving block. The clamping face of the clamping block is composed of three semi-cylindrical faces with different diameters. The diameters of the semi-cylindrical faces are the same as the corresponding diameters of workpieces. The special clamp solves the problem that according to an existing universal clamp, shaft parts with shaft rings cannot be reliably clamped, and clamping force cannot be easily controlled, and the special clamp has the advantages of being simple in structure, reasonable in design and easy to manufacture.
Description
Technical field
The invention belongs to jig field, more particularly, relate to a kind of for clamping the special fixture of the axle collar.
Background technology
In machine industry, lathe especially milling machine is widely used in processing dish class or axial workpiece.When this class part of processing, there are many parts as location, to step up face with end face or endoporus and carry out the machining such as cylindrical, end face, screw thread and axial cut-out.Concerning the larger workpiece processing of single-piece, small lot, workload, generally can directly on platen face, by adjustment, realize positioning and clamping, the position of part is determined in the setting that by machining coordinate is then.For the part that has certain batch, need by selecting relevant special fixture to reduce to reduce labour intensity, reduce part processing non-cutting time, enhancing productivity.Especially for the axial workpiece that contains the axle collar, at the needs axle collar during as retaining part, because general common fixture clamping face is single plane, therefore use plain clamp to be not easy to the control of clamping force, too pine does not have positioning action, too tightly damages surface of the work, even compression failure workpiece.
Summary of the invention
For existing universal fixturing, the axial workpiece that contains the axle collar is clamped to unreliable, the uppity problem of clamping force, the invention provides a kind of special fixture for axle collar clamping.
For addressing the above problem, the present invention adopts following technical scheme.
A kind of special fixture for axle collar clamping, comprise clamping fixture seat, slide rail, adjusting screw(rod), movable block, clamp, the lower end of slide rail is arranged on clamping fixture seat, the upper end of slide rail is stuck on the recessed edge in movable block lower end, clamp lower end is pressed on the recessed edge in upper end of movable block, and adjusting screw(rod) is meshed with movable block; The clamping area of described clamp is comprised of the semi-cylindrical of three different-diameters, and the diameter of the semi-cylindrical diameter corresponding with workpiece is identical.
Preferably, described clamp is inlayed one deck carbide alloy on its clamping area.
Preferably, in the clamping area of described clamp, three semi-cylindrical diameters are respectively 40mm, 50mm and 35mm.
Than prior art, beneficial effect of the present invention is:
(1) clamping area of clamp of the present invention is comprised of the semi-cylindrical of three different-diameters, when clamp clamps, just can clamp the axial workpiece that contains the axle collar, especially for fragile workpiece, make to clamp effect more obvious, clamping force is easy to control, and location is reliable, little to workpiece surface damage.
(2) the present invention is simple in structure, reasonable in design, is easy to manufacture.
(3) clamping area of clamp of the present invention is comprised of the semi-cylindrical of three different-diameters, the diameter of the semi-cylindrical diameter corresponding with workpiece is identical, and three semi-cylindrical diameters can clamp most this type of workpiece while being respectively 40mm, 50mm and 35mm, application surface is the widest.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is top view of the present invention.
In figure: 1-slide rail, 2-adjusting screw(rod), 3-movable block, 4-clamp.
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention.
As shown in Figure 1 and Figure 2, special fixture for axle collar clamping comprises clamping fixture seat, slide rail 1, adjusting screw(rod) 2, movable block 3, clamp 4, the lower end of slide rail 1 is arranged on clamping fixture seat, the upper end of slide rail 1 is stuck on the movable block 3 recessed edge in lower end, clamp 4 lower ends are pressed on the recessed edge in upper end of movable block 3, and adjusting screw(rod) 2 is meshed with movable block 3.
The clamping area of described clamp 4 is comprised of the semi-cylindrical of three different-diameters, and the diameter of the semi-cylindrical diameter corresponding with workpiece is identical, and described clamp 4 is inlayed one deck carbide alloy on its clamping area.
In use, by rotation adjusting screw(rod) 2, movable block 3 is under the effect of adjusting screw(rod) 2, promote slide rail 1 slides to centre on clamping fixture seat, thereby drive the clamping of moving and complete of clamp 4 to move, now the clamping area of clamp 4 matches with side surface of workpiece, completes location.Otherwise counter-rotating adjusting screw(rod) 2 can loosen square cross.
