Abstract

The utility model discloses a swing head mechanism for a superfinishing machine. The key improvement is that the swing head mechanism comprises a casing, a driving motor and a driving mechanism fixedly arranged at one end of the casing, an eccentric slider mechanism fixedly disposed at the center of the casing, a swinging mechanism arranged at the other end of the casing via a bearing, and a telescopic device arranged at the center of a connecting rod between the eccentric slider mechanism and the swinging mechanism. The utility model has the advantages that swing heat mechanisms of the same group can be used for processing two arc sections of a bearing raceway, or for processing symmetric half raceways at two ends of an automobile hub bearing just by sliding the casing; and during the whole processing process, workpieces need not to be positioned again, and all one needs to do is slide the casing, preventing secondary positioning error caused by workpiece reposition and enhancing precision and efficiency of processing bearing raceways.

Technical field

The utility model has related to a kind of bearing channel processing unit (plant), particularly a kind of oscillating head mechanism that is applied on the Superfinishing machine.

Background technology

Bearing is a kind of fixed member the most frequently used in the mechanical field, main effect is the relative motion position between definite axle and other parts, rise and support and guide effect, generally the direction according to the load that bearing bore can be divided into it journal bearing, axial thrust bearing and radial-thrust bearing, it is one of critical component in the machine driving, the quality of bearing quality can directly influence the height of plant equipment running efficiency and running accuracy, so the processing of bearing is the technology emphasis in the field of machining always, the general Superfinishing machine that adopts of existing bearing raceway processing, arcuate groove at the process middle (center) bearing is divided into two parts symmetrical processing, be provided with two groups as the swing of existing Superfinishing machine is first, half of a raceway of the corresponding processing of each group, reprocess second half after in the middle of operation, will and reorientating with the workpiece tune, increased one-time positioning, so just strengthened the workpiece manufacturing tolerance, and some bearing itself only respectively is provided with half raceway groove at two ends, perhaps raceway groove is to have the circular arc of two sections different curvature to constitute, picture automobile hub unit bearing, the biserial angular contact bearing, self-aligning roller bearing, four-point contact ball etc., bring great inconvenience to production and processing, more in addition, two groups of oscillating head mechanisms are set cause whole Superfinishing machine structure bigger later on, wasting space.

The utility model content

The utility model provides a kind of can reduce the bearing channel mismachining tolerance, and can save the oscillating head mechanism on the Superfinishing machine of being applied in complete machine space.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of oscillating head mechanism that is applied on the Superfinishing machine, its key improvements is: comprise housing, be fixedly installed on housing one end drive motors and transmission mechanism, be fixedly installed on housing middle part eccentric shoe mechanism, by means of bearing be arranged on the swing mechanism of the housing other end and be located at eccentric shoe mechanism and the swing mechanism input between connecting rod; The output shaft of described transmission mechanism links to each other with the input of eccentric shoe mechanism, the output of eccentric shoe mechanism and rod hinge connection, and other end of connecting rod and swing mechanism input are hinged, and the output of swing mechanism is fixed with the oilstone folder; Described connecting rod middle part is provided with retractor device.

Above-mentioned eccentric shoe mechanism comprises power transmission shaft, is fixedly installed on the driven pulley on the power transmission shaft, position adjustable slide block, slide block and the rod hinge connection that is fixedly installed on the swiveling wheel of power transmission shaft end and is fixedly installed on the swiveling wheel end face.

Above-mentioned swing mechanism comprises swing head and the oilstone folder that is installed in swinging axle on the housing, is fixedly mounted on the eccentric wheel of swinging axle one end and is arranged on the other end of swinging axle by means of bearing; Described eccentric wheel and rod hinge connection; Described swing head and the coaxial setting of swinging axle; Described connecting rod middle part is fixed with cylinder or hydraulic cylinder; Described oilstone folder is installed in the first side of swing, fixed bar and the coaxial setting of swinging axle by means of fixed bar.

Adopt the beneficial effect that technique scheme produced to be: one group of oscillating head mechanism only is set on Superfinishing machine, and the length that being used in the oscillating head mechanism drives eccentric connecting rod can be adjusted, the length of adjusting connecting rod can realize that yaw swings at two diverse locations, can realize that same group of oscillating head mechanism can be used for two sections circular arcs of machining bearing raceway groove, perhaps can only need slider case just can realize the processing of half raceway groove that the automobile hub bearing two ends are symmetrical, in whole process, do not need workpiece is reorientated, only need slider case, avoid the secondary position error that produces when reorientating because of workpiece, improve the machining accuracy and the working (machining) efficiency of bearing channel, one group of oscillating head mechanism only is installed simultaneously, simplify the structure of Superfinishing machine, save the space.
