Abstract
A special fixture for processing of eccentric semicircles of levers for automobiles consists of a fixture base, a fixture base end face, a bolt, a bolt end face, a positioning nail, a semi-cylinder portion, a positioning shaft and a workpiece external spherical surface. A cylinder with an eccentric inner bore, a center hole seat, the positioning shaft, the ball-head positioning nail and the hexagonal bolt are all arranged in the fixture base, two cylinders with eccentric inner bores are arranged on two sides of the fixture base, inner bores coaxial with an outer circle to be processed are arranged on the outer side of the two cylinders, the center hole seat is inserted into the inner bores, inner bores coaxial with a hole of the workpiece to be processed are arranged on the inner sides of the two cylinders, and the positioning shaft is inserted into the inner bores, so that shortcomings of a conventional device can be overcome effectively. In addition, the special fixture solves problems of processing eccentric semicircles of levers, is convenient in clamping and high in universality, and is capable of guaranteeing that levers have higher dimension precision.
Description
Technical field
The utility model relates to a kind of clamp for machining of eccentric work piece, and especially a kind of automobile belongs to the Machining Technology field with the eccentric semicircle Special Fixture for Machining of lever.
Background technology
According to retrieval, existing automobile adopts thimble to hold out against endoporus with the eccentric semicircle of lever or processes eccentric excircle by common mandrel.And lever is incomplete cylindrical and endoporus just can't adopt thimble to push up its endoporus, and endoporus is that blind hole also can't be by mandrel, and external form also is difficult to look for anchor point than complexity.Bring a lot of inconvenience for the processing automobile accessory.
Summary of the invention
The purpose of this utility model will provide a kind of automobile eccentric semicircle Special Fixture for Machining of lever exactly, and it can overcome the defective that old-fashioned processing method is brought.The purpose of this utility model is to realize like this, the automobile eccentric semicircle Special Fixture for Machining of lever, formed by clamping fixture seat, clamping fixture seat end face, bolt, bolt end face, locating pin, locating pin bulb, screw, bolt, centre bore seat, centre bore, cylinder, column part, semicolumn part, locating shaft, workpiece, workpiece Internal Spherical Surface, workpiece spherical outside surface, it is characterized in that: the cylinder that is provided with eccentric inner hole in the described clamping fixture seat, the centre bore seat, locating shaft, bulb-type locating pin and hex bolts; A screwed hole is arranged on the described clamping fixture seat, be fastened with a location hex bolts in the screwed hole; Clamping fixture seat is provided with the radial location pin-and-hole corresponding with workpiece to be processed, and its interpolation sets a backing pin, and the location backing pin is workpiece radial direction location; The clamping fixture seat both sides also are provided with the cylinder of two eccentric inner holes, the two cylinders outside is provided with the endoporus coaxial with cylindrical to be processed, be fitted with the centre bore seat in it, the centre bore seat is provided with the centre hole concentric with cylindrical to be processed, two cylinder inboards are provided with the coaxial endoporus in workpiece to be processed hole, are fitted with locating shaft in it.
The technical problems to be solved in the utility model provides a kind of convenient mounting and clamping, the eccentric semicircle Special Fixture for Machining of lever simple in structure, cheap, as can to guarantee machining accuracy, and these anchor clamps both can be used on the lathe Vehicle Processing to off-centre half cylindrical, also can be used on the grinding machine mill processing, improve the versatility of anchor clamps eccentric excircle.
Description of drawings:
Fig. 1 is the front view of the utility model anchor clamps;
Fig. 2 is the partial sectional view that is welded on the cylinder that welds on the clamping fixture seat among Fig. 1;
Fig. 3 is the cutaway view of A-A among Fig. 2;
1-clamping fixture seat, 1a-clamping fixture seat end face, 2-bolt, 2a-bolt end face, 3-locating pin, 3a-locating pin bulb, 4-screw, 5-bolt, 6-centre bore seat, 6a-centre bore, 7-cylinder, 7a-column part, 7b-semicolumn part, 8-locating shaft, 9-workpiece, 9a-workpiece Internal Spherical Surface, 9b-workpiece spherical outside surface
The specific embodiment:The utility model is described in further detail below in conjunction with accompanying drawing
In the drawings, the utility model automobile eccentric semicircle Special Fixture for Machining of lever, when specifically implementing,
⑴ go into the endoporus of column part 7a with a centre bore seat 6 and an end plug-in mounting of locating shaft 8, and the other end of locating shaft 8 gos deep in the semicircle orifice of workpiece 9;
⑵ be welded on cylinder 7 on the clamping fixture seat 1, notes relative position;
⑶ match with clamping fixture seat end face 1a with the end face of screw 4 with locating pin 3, with locating pin bulb 3a top tight workpiece Internal Spherical Surface 9a; With bolt 2 top tight workpiece spherical outside surfaces;
⑷ half periphery of bolt 5 top tight workpieces 9,
⑸ during Vehicle Processing, a folder one top, three-jaw clamps an end column part 7b, and thimble holds out against centre bore 6a; Mill adds man-hour, and Double Tops hold out against centre bore 6a;
⑹ semicolumn part 7a is used for the measurement to workpiece 9 half cylindrical external diameters;
The utility model has not only solved the processing problems of the eccentric semicircle of lever, and double column part 7b can carry out the measurement of semicircle external diameter, measure the ultimate range of two semicircle external diameters with slide measure or outside micrometer, deduct the radius of semicolumn part 7b, can obtain lever half cylindrical outside dimension.Add man-hour, with the lever clamping between two locating shafts, be concerned about the off-centre that generation is required by the off-centre between locating shaft and centre bore seat, thereby make the lever endoporus that is fixed on the locating shaft corresponding eccentric throw be arranged, and then can process required off-centre operation cylinder with respect to machine tool chief axis.
The utility model has solved the processing problems of eccentric half cylindrical of lever, its convenient mounting and clamping, and the versatility height can also guarantee that lever has higher accurate to dimension.
