Abstract

The utility model discloses gear face grinding tooling, including upper fixing element and lower fixture, fixed part includes end cap and is fixed on the lower surface of end cap and the cylinder set with end cap with central axis；The diameter of the cylinder is less than the diameter of the end cap and both combine to form the limiting section of restricted gear axial movement；The lower fixture includes substrate and the fixed part being fixed on substrate；The mounting hole of inserting cylinder is offered on the fixed part；Running through at the center of fixed part and lower fixture has fixing hole.It can guarantee that the depth of parallelism of the upper and lower ends face of each work gear to be added at ± 5 microns.

Description

Gear face grinding tooling

Technical field

Gear machining apparatus technical field is the utility model is related to, more particularly to a kind of frock of gear face polishing.

Background technology

Gear as shown in Figure 1, the depth of parallelism of the upper and lower ends face of gear is at ± 5 microns；Prior art, gear are fixed Processed on the fixture of sander；But clamping twice is carried out in process, common fixture can be deposited in clamping process In rigging error；It cannot be guaranteed that the depth of parallelism of the upper and lower ends face of each work gear to be added is at ± 5 microns；Therefore, it is necessary to develop A kind of new gear fixing device.

Utility model content

The purpose of this utility model is to provide a kind of gear face grinding tooling, and it can guarantee that the upper of each work gear to be added The depth of parallelism of lower both ends of the surface is at ± 5 microns.

Above-mentioned technical purpose of the present utility model technical scheme is that：Gear face reconditioning work Dress, including upper fixing element and lower fixture, fixed part include end cap and are fixed on lower surface and and the end cap of end cap The cylinder set with central axis；The diameter of the cylinder be less than the end cap diameter and both combine to form it is restricted The limiting section of gear axial movement；The lower fixture includes substrate and the fixed part being fixed on substrate；The fixed part On offer inserting cylinder mounting hole；Running through at the center of fixed part and lower fixture has fixing hole.

Further set, the fixed part is the boss with end cap with diameter.

The endoporus of work gear to be added is shoulder hole, first with standard cartridge polishing endoporus, makes endoporus vertical with outer face Degree is within 0.01mm；Then this frock is recycled to process the depth of parallelism of gear both ends of the surface and flatness；

There is upper and lower cascaded surface, shoulder hole just coordinates with end cap, boss, and work gear to be added is placed in the shoulder hole On lower fixture, upper fixing element is inserted into the shoulder hole of work gear to be added, and three is secured firmly to by bolt through fixing hole Together.The periphery of boss and shoulder hole, which coordinate, to be limited work gear to be added and moves radially, the upper surface of boss as lower reference plane, Downstairs face is propped up, coordinates with it and limits gear axial movement to be processed；Cylinder passes through shoulder hole and the mounting hole on boss Coordinate and fix, limit moving radially for work gear to be added；Limiting section props up the upper cascaded surface of gear to be processed；Limit tooth to be processed Wheel axial movement.Generation processing gear is processed using this frock；The depth of parallelism of the gear upper and lower end face processed ± 5 microns it It is interior, and axiality is high.

Embodiment

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

The utility model to process gear 1 as shown in figure 1, there is a through hole at its center, the through hole is shoulder hole 11, should There is upper and lower cascaded surface in shoulder hole 11.The end face grinding tooling of gear 1 as shown in Figure 4, it includes upper fixing element 2 and lower solid Determine part 3.Referring to figs. 2 and 5 the shape picture plug of upper fixing element 2；It includes end cap 21 and is fixed on the lower end of end cap 21 Face and the cylinder 22 set with the coaxial line line of end cap 21.The diameter of cylinder 22 is less than the diameter of end cap 21 and both combine The limiting section 23 moved axially formed with limiting gear 1.A counterbore 24 is provided with the central part of end cap 21, counterbore 24 is used to put Put nut.A through hole 25 for being less than the aperture of counterbore 24, the through hole are provided with the central part of cylinder 22 and along its axial direction 25 are connected with counterbore 24.

See Fig. 3, lower fixture 3 includes substrate 31 and the fixed part being fixed on substrate 31.Fixed part is boss 32, convex The mounting hole 33 of inserting cylinder 22 is offered at the center of platform 32.A through hole 34 for running through boss 32 is provided with substrate 31, Counterbore 24, through hole 25 and the same central axis of the three of through hole 34 and constitute fixing hole.

Installation process：First work gear 1 to be added is placed on the boss 32 of lower fixture 3, then upper fixing element 2 is inserted into On work gear 1 to be added, finally, three is fixed through lower fixture 3, upper fixing element 2 with bolt.

Specific embodiment is only that it is not to limitation of the present utility model, this area to explanation of the present utility model Technical staff can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but only All to be protected in right of the present utility model by Patent Law.
