Description

The accurate calibration clamp for machining of a kind of axial workpiece
Technical field
The utility model relates to a kind of fixture, the accurate calibration clamp for machining of especially a kind of axial workpiece.
Background technology
During the axial workpieces such as the current battery sleeve at oil drilling platform are produced, often need to be in cylinder cylinder processing method to equally distributed aperture or groove, part material is generally 1Cr18Ni9Ti, because stainless steel has, toughness is large, calorific intensity is high, thermal conductivity factor is low, work hardening is serious, heat in metal cutting is many, the characteristics such as heat radiation difficulty, cause machining difficulty.In machining, easily cause cutter point of a knife place cutting temperature high, it is serious that smear metal adheres to cutting edge, easily produces built-up edge, and cutter is easy to wear, and because hole to be processed or groove more easily cause fractureing of cutter.
Processing technology is arranged on small-sized jig boring machine that equipment precision is higher equally or milling machine and processes, the processing cost of small-sized jig boring machine or milling machine is low on the one hand, be placed on the other hand small-sized jig boring machine or milling machine processing, operator can grasp the cutter situation in controlled working process.But because small-sized jig boring machine or milling machine itself are without indexing structure, the calibration that can only use relatively heavy index dial to carry out equally distributed aperture is processed, and uses this clamping method efficiency low in reality processing.
Index dial clamping parts is axially without location, in process, process hole, place or a groove, operator's hand rotation index dial, forwards position to be processed to and processes another hole, place, the probability that one side operator in rotation process misunderstands scale is high, and efficiency is quite low on the other hand.In recent years, along with model task surge, can the production efficiency of part become key that punctual delivery, thus processing is evenly distributed on cylinder cylinder normal direction aperture or groove and proposed a kind of clamping means of efficient stable.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of good stability, a kind of quick-clamping indexing means that accuracy is high, realizes the accurate calibration of axial workpiece.
The technical solution of the utility model is: the accurate indexing fixture of a kind of axial workpiece, comprise end clamping device, calibration piece, base, two end clamping devices are arranged on respectively the left and right sides of base and are provided with corresponding adjustable hold down gag, axial workpiece clamp by two end clamping devices and when axial workpiece lateral surface be fixed with one division piece, one side of calibration piece is regular hexagon body, the opposite side of calibration piece is the equilateral triangle body with fillet mating with regular hexagon body, and calibration piece is provided with an endoporus matching with axial workpiece cylindrical.
In the middle of three fillets of the equilateral triangle body of calibration piece, be processed with screwed hole, this screwed hole and endoporus connect, and the axis of screwed hole is vertical with interior axially bored line and coplanar, can clamp part by the cooperation of screwed hole and screw.
End clamping device is square-outside and round-inside shape, and end clamping device comprises upper clamping block, lower clamp, while clamping part outer, leaves the gap of 0.5mm between upper and lower clamp.
Six working faces that side is calibration piece of the regular hexagon body of calibration piece.
The beneficial effects of the utility model are: meet quick-clamping indexing means by designing a kind of easy device, the demand of quick index in process.Parts fixation is easy, and in process, calibration is accurate rapidly, and therefore, parts size precision meets designing requirement completely, has greatly improved production efficiency, criticizes product task strong base support is provided for model.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
As Figure 1-3, the accurate indexing fixture of a kind of axial workpiece, comprise end clamping device 1, calibration piece 2, base (not shown), two end clamping devices 1 are arranged on respectively the left and right sides of base and are provided with corresponding adjustable hold down gag, axial workpiece 3 clamp by two end clamping devices 1 and when axial workpiece 3 lateral surface be fixed with one division piece 2, one side of calibration piece 2 is regular hexagon body 22, the opposite side of calibration piece 2 is the equilateral triangle body 21 with fillet mating with regular hexagon body 22, calibration piece 2 is provided with an endoporus matching with axial workpiece 3 cylindricals.
In the middle of three fillets of the equilateral triangle body 21 of calibration piece 2, be processed with screwed hole 23, this screwed hole 23 connects with endoporus, and the axis of screwed hole 23 is vertical with interior axially bored line and coplanar, can clamp part 3 by the cooperation of screwed hole 23 and screw.
End clamping device 1 is square-outside and round-inside shape, and end clamping device 1 comprises upper clamping block 11, lower clamp 12, while clamping part outer, leaves the gap of 0.5mm between upper and lower clamp.
Six working faces that side is calibration piece 2 of the regular hexagon body 22 of calibration piece 2.
When concrete enforcement, calibration piece 2 is along with part 3 rotates together, and the working face of calibration piece 2 is through accurately machined burnishing surface.As axial workpiece 3 need to be processed into hexahedron, the first working face of the corresponding calibration piece 2 of part 3 first machined surfaces, when processing a face, part 3 forwards to after next machined surface, when the jerk value that utilizes dial gauge or amesdial to measure 2 second working faces of calibration piece meets the requirements, get final product second machined surface of positioning shaft parts 3.
That in above-described embodiment and description, describes just illustrates principle of the present utility model and most preferred embodiment; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
