Abstract

The utility model relates to an automatic race position-regulating device for a bearing inner and outer raceway grinder. A swing rod is hinged on a support seat component. An elastic support member is arranged between the support seat component and one end of the swing rod. The elastic support member is connected to the support seat component. A micro-regulating contact head is arranged on the other end of the swing rod. One end of a mechanical sensing device is provided with a sensing contact head, and the mechanical sensing device is arranged on the relative position of the elastic support member of the support seat component. The automatic race position-regulating device for a bearing inner and outer raceway grinder has the advantages that An obsolete work process and equipment for printing signs are cancelled. The automatic race position-regulating device for a bearing inner and outer raceway grinder can automatically regulate the positions of the annular raceways of grinding bearings on the center of a processed work piece. The symmetrical degree of the annular raceways of the grinding bearings is high. The efficiency for grinding raceways is enhanced, grinder equipment is reduced, and cost is lowered.

Description

Automatic race position-regulating apparatus for bearing inner and outer raceway grinder

The utility model belongs to a kind of bearing inner and outer ring raceway groove car mill and adjusts ditch position device automatically.

At present, the processing of bearing inner and outer ring raceway groove in order to assert datum level, is stamped the marking at the inner and outer ring end face earlier, thereby is needed PRN device before processing.Inner and outer ring is after Vehicle Processing, though the width of pieces O.K. is in deviation range, because of the error of upper and lower bound, behind the Vehicle Processing raceway groove, its position all not at the workpiece center, causes at mill to add man-hour, need the more time, could come the raceway groove cent(e)ring, it is low therefore to grind working (machining) efficiency.

Because existing Vehicle Processing method is difficult to improve the product precision, thereby influences assembling, outward appearance and service property (quality).

The purpose of this utility model provides a kind of bearing inner and outer ring raceway groove car mill and adjusts ditch position device automatically, operation is printed in cancellation, during the car mill, need not assert datum level, can adjust the slide carriage travel position automatically, cause raceway groove in the workpiece center by its margin of error, not only simplified operation, and the symmetrical precision of the raceway groove that improves workpiece, raise the efficiency the saving fund.

The purpose of this utility model is achieved in that it comprises mounting assembly, gland, the main points of its technical scheme are: hinged fork on mounting assembly, between mounting assembly and fork one end elastic supporting member for supporting optical member is housed, elastic supporting member for supporting optical member is connected on the mounting assembly, and the fork other end is equipped with the fine setting contact; Mechanical sensing device one end has sensor contact, and it is arranged on the relative position of elastic supporting member for supporting optical member of mounting assembly, controls full sensor-based system action with it, and the other end of mechanical sensing device connects skewback, and the inclined-plane of skewback contacts with gland.

The said mechanical sensing device of the utility model is made up of skeleton, lever and drive link, and lever is hinged in the skeleton, and lever and drive link all are contained in the skeleton for hinge connects.

The utility model has the advantages that: cancelled outmoded operation of franking and equipment, the circular groove road that can adjust car, mill bearing automatically is in the center of processing work, and bearing channel symmetry height improves grinding raceway groove efficient, has reduced grinding machine equipment, has reduced cost.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is an example structure schematic diagram of the present utility model.

Fig. 2 is a sensing contact structure schematic diagram of the present utility model.

See Fig. 1,2, the concrete structure of the utility model embodiment is as follows:

Form by mounting assembly, sensing device and skewback assembly etc.The mounting assembly part: be made of bearing 4, adjustment bearing 5, slide block 6 and fork 7 etc., adjusting bearing 5 is that the assembling of adjusting mounting assembly compensates its error.Slide block 6 is loaded on to be adjusted on the bearing 5, can move up and down, and its lower end hinge connects fork 7, and slide block 6 upper ends connect elastic supporting member for supporting optical member, and this part is by a spring 3 and touch cap 2 and forms, touches cap 2 and is close to upper end one side of closing fork 7, and the lower end of fork 7 is equipped with and is finely tuned contact 15.

Sensing device and skewback assembly:

This device belongs to mechanical sensing, form by sensor contact 1, skeleton 8, lever 9 and drive link 10, concrete structure is as follows: the head end of sensing device is equipped with sensor contact 1, and contact 1 and lever 9 one ends hinge connect, and lever 9 other end drive links 10 hinges connect, lever 9 middle parts hinge is connected in the skeleton 8, terminal drive link connects with skewback 11, and the centre also is provided with rotatable micro actuator 14, at skewback 11 outsides dress gland 12, gland 12 is close to gland 12 and is combined on the skewback 11 by extension spring 13 tensions.

Operation principle: fork 7 lower end contacts 15, when contact workpiece 16(bearer ring) outer face, and the oscillating quantity of the contact 15 of workpiece developed width decision fork 7, thereby cause sensor contact 1 move left and right, the action of sensing full device moves up and down skewback 11, promotes gland 12 left and right displacement.When the machine slide backstay touched gland 12, slide carriage is displacement no longer, and guaranteed the position location, and the move left and right amount of gland 12 is a workpiece deviation half.

Claims

1, a kind of bearing inner and outer ring raceway groove car grinds ditch position automatic regulating apparatus, comprise mounting assembly, gland, it is characterized in that: hinged fork on mounting assembly, between mounting assembly and fork one end elastic supporting member for supporting optical member is housed, elastic supporting member for supporting optical member is connected on the mounting assembly, and the fork other end is equipped with the fine setting contact; Mechanical sensing device one end has sensor contact, and it is arranged on the relative position of elastic supporting member for supporting optical member of mounting assembly, and the mechanical sensing device other end connects skewback, and the inclined-plane of skewback contacts with gland.

2, ditch according to claim 1 position automatic regulating apparatus, it is characterized in that: mechanical sensing device is made up of skeleton, lever and drive link, and lever is hinged in the skeleton, and lever and drive link all are contained in the skeleton for hinge connects.
