Description
Technical field
The utility model belongs to machining auxiliary clamping device.
Background technology
In prior art, the clamping of major diameter multihole lamina workpiece is adopted to the mode clamping of claw and equal-height padding iron, there are the following problems for it: the fulcrum of high parallels is limited, very little with the contact area of workpiece, in process, workpiece rigidity is not enough, easily causes larger cutting deformation.When adopting machine tool jaw to carry out clamping, the bad control of clamping dynamics, clamping dynamics is too small adds workpiece movable in man-hour, just directly causes the clamping deformation of workpiece when clamping dynamics is excessive.Adopt claw to carry out clamping, the measurement after the processing of cylindrical still needs the method adopting auxiliary parallels, and operation is wasted time and energy.
Utility model content
For solving the problems of the technologies described above, the utility model proposes following technical scheme: a kind of major diameter multihole lamina workpiece turnning and milling fixture, it has following features: the ring-type riser composition base body that the vertical link of boards radially distributed is equidistant.Vertical gusset is provided with the screw I be arranged symmetrically with.Friction top is matched with this screw I by screw I.The excircle Side symmetrical of ring-type riser fixes at least 4 to the bearing being provided with survey mass and jackscrew.The corresponding stop block in a pair position is at least fixed at the upper surface of ring-type riser excircle.The two ends of stop block are provided with screw II, and the screw rod with through hole pierces in screw II.Distance between the outer surface of stop block is less than the diameter of workpiece.The corresponding stop block screw II in a pair position is fixed on the upper surface of maximum ring-type riser.The vertical gusset interlaced arrangement radially distributed.Jackscrew front end is fixed with aluminium cap.
The utility model that have employed technique scheme has following technique effect: make clamping workpiece firmly convenient, fit well with workpiece, be convenient to measure, can effectively be out of shape by controlled working, obtain good effect aborning, ensure that crudy is enhanced productivity.

Detailed description of the invention
The base body of the utility model major diameter multihole lamina workpiece turnning and milling fixture is welding structural element, workpiece 11 plane is played to the effect of integrated support, it is by 3 ring-type risers 1, many that radially distribute vertical gussets 2, the excircle Side symmetrical of ring-type riser 1 fixes at least 4 to being that 8 bearing assembly weldings being provided with survey mass 6 and jackscrew 7 form, and in present case, 4 to namely 8.For carrying out stress-removal heat treatment after welding.Top and bottom are polished surface, are processed with screw 3 above, for the lid 4 that is fixed and clamped by screw I-5, also by the fastening stop block 8 of screw II.Friction top 4 cylindrical turning after workpiece 11 perforate adds man-hour, from workpiece end face workpiece pressing 11, workpiece 11 is fitted tightly in base body.Jackscrew 7 thread size is M42, totally 8, and workpiece 11 is played to the effect of centering clamping, front end can be fixed with aluminium cap, and the cylindrical of workpiece 11 is not hindered by card in process.Survey mass 6 has 8 pieces altogether, is fixed in base body symmetrically and evenly, as the benchmark of measuring workpieces 11 cylindrical after turning inner circle, is processed with M42 screwed hole, can provides support for jackscrew 7, for screwing jackscrew 7.By measuring internal diameter after turning as benchmark, the measurement of workpiece 11 cylindrical can also be carried out.Friction top 4 is along the circumferential direction evenly arranged, and workpiece 11 is evenly clamped.Stop block 8 is symmetrically distributed in outer ring circumferentially, and physical dimension is less than the notching dimension on workpiece 11, and in the inner side of workpiece 11 cylindrical, has dodged Excircle machining position, and Excircle machining clamped one time is completed.It is fastening by screw II-12.This and friction top 4 together use and are clamped by workpiece 11.Two ends due to stop block 8 are provided with the screw II that screw II is processed with M12, can be used for screwing screw rod 9.
Screw rod 9 is respectively processed with φ 5.5 through hole 10, is regulated by spanner, screwing and unclamping for screw rod 9.Realize the object from circumferential clamping workpiece 11.
That the base body of the utility model fixture is placed in turn-milling machine tool work table rotation center in actual process, by cylindrical and the end face centering of fixture, with claw by securing for the utility model fixture.
