Abstract
The utility model is suitable for die standard component manufacturing industry. A fixture for processing a square-shaped circular boss positioning female die mainly comprises a matrix and a chuck, wherein the matrix is provided with a screw hole therein, the chuck is arranged in the matrix and provided with a location hole, an internal diameter of the location hole is greater than an external diameter of a workpiece, a bottom of the chuck is provided with a threaded through hole which is connected with the screw hole inside of the matrix, and an external diameter of the chuck is formed by a cylindrical surface and a conical surface. The fixture in the utility model has simple structure, changes clamping way of workpieces, wherein the location hole of the chuck is designed into several kinds of specifications, size of the internal diameter of the location hole is enlarged with 0.02 to 0.05 mm according to size of the circle boss of the workpiece; in addition, the fixture in the utility model changes processing technology route for the workpieces, i.e., an inner bore can be processed by an inner bore grinding machine rather than a jig grinding machine, thus raw materials used for a former lengthening part are saved, and the purposes of saving the raw materials and reducing manufacturing cost are realized.
Description
Technical field
The utility model is applicable to mould standard spare manufacturing industry.
Background technology
Automobile manufacture industry user's profile boss platform location die, it is that profile is square, middle material-dropping hole is circular, adopts the standard concave module of boss platform location.Because the material-dropping hole of mould product one end and the setting circle boss of the other end have axiality and perpendicularity requirement.For guaranteeing the positional precision of product, at present all adopt jig grinder to carry out the processing of blanking endoporus, adding man-hour need be to behind the clamping workpiece, proofreaies and correct again, and for making calibration of workpieces convenience in the processing, product blanking nose end must be extended as the processing technology benchmark, cut away elongated portion after the processing again.This not only wastes raw material, and the manufacturing cost increase, makes the selling price height of product.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of side's profile boss platform location die processing jig is provided, and is simple in structure, convenient mounting and clamping, and cancellation lengthening technological datum part improves the raw-material utilization rate of product, reduces manufacturing cost.
The technical scheme that the utility model technical solution problem is adopted is: square profile boss platform location die processing jig, tool mainly comprises carcass and dop, offer screw in the carcass, dop is installed in the carcass, dop offers locating hole, and the internal diameter of locating hole is greater than the external diameter of workpiece, and the dop bottom is threaded via hole, screw in screw thread via hole and the carcass is communicated with, and the dop external diameter is cylinder and conical surface formation.
Described carcass inner bolt hole is the concave station inner bolt hole, in the concave station inner bolt hole spring is installed.
The end face of described dop conical surface part has cross recess.
Described locating hole internal diameter is greater than workpiece external diameter 0.02mm～0.05mm.
The utility model is simple in structure, changes the installation way of workpiece, and the dop locating hole is designed to several specifications, and the locating hole internal diameter size amplifies 0.02mm～0.05mm according to workpiece boss platform size; External diameter is processed into the cylinder and the conical surface, and have a cross recess, cylinder play the guiding role when assembling with carcass, the conical surface plays the effect of locking workpiece, for preventing that the dust in the workpiece process from entering on the contact surface of dop and carcass, in the dop cross recess, be filled with fluid sealant, can in carcass, freely clamp for making dop, lax, spring is installed in carcass, when tightening screw, dop moves in carcass, under the effect of the conical surface, the dop endoporus shrinks, play the effect of clamping work pieces, when relaxing screw, the spring between dop and carcass plays the power effect of unloading, dop is outwards moved, reach lax workpiece purpose.The utility model tool changes the workpiece machining process route, and jig grinder is processed endoporus, changes endoporus grinding machine bed processing endoporus into, saves the raw material that originally need elongated portion, reaches to save material, and reduces the purpose of manufacturing cost.

Fig. 2 the utility model jig structure schematic diagram.
Fig. 3 is the utility model side view.
Fig. 4 is the utility model tool working state figure.
Among the figure, 1. carcass; 2. spring; 3 screws; 4. dop; 5. workpiece; 6. material-dropping hole; 7. setting circle boss; 8. emery wheel bistrique; 9. screw; 10. cylinder; 11. the conical surface; 12. screw thread via hole; 13. cross recess; Locating hole 14.
The specific embodiment
Among Fig. 4, tool 1 clamping on the grinder scroll chuck, according to the size of workpiece boss platform, is selected corresponding dop 4 during work, be installed on the tool carcass 1; Correcting fixture carcass 1 cylindrical and section, after finishing, the workpiece 5 of needs processing is installed on the dop 4, and when tightening screw 3, dop moves in carcass, under the effect of the conical surface, the dop endoporus shrinks, and plays the effect of clamping work pieces, guarantees that boss you face and dop end face closely are close together, this moment, workpiece no longer needed to proofread and correct, and can adopt emery wheel bistrique 8 to begin processing.When relaxing screw 3 after machining, the spring 2 between dop and carcass plays and unloads the power effect, and dop is outwards moved, and reaches lax workpiece purpose.
