Abstract
The utility model relates to a kind of AT gearbox planetary gear gear grinding toolings, workpiece is in chuck body, when processing, it is moved up into clamp head under internal expanding is top, hold out against clamp head, so that the workpiece being mounted in clamp head is compacted, internal expanding is top to be fixed by adjusting bolt, and then roll flute grinding wheel carries out Gear shape process.The utility model has abandoned traditional ringfeder structure, pass through top the holding out against for chuck body of internal expanding, it can be to avoid the interference in worm abrasion wheel process, realize the fixation of pinion gear workpiece, guarantee that teeth directional spiral angular displacement guarantees within 0.01 range when roll flute processing, and the accumulative bounce of gear is within 0.01 range.
Description
Technical field
The utility model relates to a kind of AT gearbox planetary gear gear grinding toolings to be applicable in for the roll flute process of Gear Processing
In all kinds of small size planetary gears.
Background technique
Currently, roll flute fabrication design is at gland and ringfeder structure, in order to meet processing request axially and radially.
Radial accuracy design: using ringfeder structure to meet precision of grinding teeth requirement under normal circumstances, and the inner hole that rises guarantees concentricity requirement, mill
Tooth form is not ground partially after tooth, and teeth directional does not tilt, and deviation is in acceptability limit；Axial accuracy Design: to prevent in roll flute process
The small variations up and down of workpiece, workpiece inclination, upper press cover design are indispensable.However for small size workpiece, ground
The limitation ringfeder scope of design of tooth machine clamp is relatively narrow, even if designing the ringfeder of small size, is also difficult to ensure when making ringfeder
Required machining accuracy, service life effect substantially reduce；For on gland design, the end face of small size workpiece must use thin
The lesser gland of the contact area of wall is just able to satisfy its requirement.
Utility model content
The purpose of the utility model is to overcome the above deficiencies in the existing technologies, and provide a kind of use and push up the formula that rises
Structure meet positioning workpiece diameter and upper surface requirement, axially and radially simultaneously guarantee processing stability AT speed change
Case rows star-wheel gear grinding tooling.
The technical scheme in the invention for solving the above technical problem is: a kind of AT gearbox planetary gear gear grinding tooling,
Top including upper dead head, chuck body, internal expanding, compressed spring is mounted in dead head, the lower end of the compressed spring with
The top upper surface cooperation of internal expanding, the top top of the internal expanding are equipped with adjustment bolt, and the internal expanding is top with chuck body work
Condition cooperation.
Preferably, the chuck body upper end is clamp head, the internal expanding is top to be cooperated with clamp head operating condition.
The utility model workpiece is in the chuck body, and when processing, internal expanding is top to be moved down, by adjusting bolt presses work
Part, then roll flute grinding wheel carries out Gear shape process.The utility model has abandoned traditional ringfeder structure, top for fixture by internal expanding
Ontology is held out against, and can be realized the fixation of pinion gear workpiece to avoid the interference in worm abrasion wheel process, be guaranteed roll flute processing
When teeth directional spiral angular displacement guarantee that within 0.01 range, and the accumulative bounce of gear is within 0.01 range.
The utility model slightly changes the top size of internal expanding according to the design of the planetary gear of different inner diameters size, by adjusting interior
Rise and top adjustment bolt position or replaces holddown spring and can satisfy the needs of different workpieces processing, application and the quick letter of replacement
Just, practicability is very strong.
The utility model compared with prior art, has the following advantages that and effect: 1, using unitary design, structure is simple
Reliably, convenient for disassembly and assembly；2, various sizes of workpiece requirement is met using bolt regulating device；3, according to the row of different inner diameters size
The top size of internal expanding slightly change in star-wheel design, by adjusting the top adjustment bolt position of internal expanding or replace holddown spring can be with
Meet the needs of different workpieces processing, strong operability, stability is good.
Detailed description of the invention
Fig. 1 is the utility model embodiment structural schematic diagram.
Fig. 2 is that the utility model embodiment holds out against state partial enlargement diagram.
In figure: upper dead head 1, chuck body 2, internal expanding be top 3, adjustment bolt 4, compressed spring 5, clamp head 6, workpiece 7.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is pair
The explanation of the utility model and the utility model is not limited to following embodiment.
Referring to Fig. 1-2, AT gearbox planetary gear gear grinding tooling in the present embodiment, including the upper dead head being connect with lathe
1, the chuck body 2 that connect with machine tool fixture interface, internal expanding top 3, compressed spring 5 is mounted in dead head 1, compressed spring
5 lower end and the upper surface of internal expanding top 3 cooperate, and the top of internal expanding top 3 is equipped with adjustment bolt 4, internal expanding top 3 and fixture sheet
The cooperation of 2 operating condition of body.
2 upper end of the present embodiment chuck body is clamp head 6, and internal expanding top 3 and 6 operating condition of clamp head cooperate, in clamp head 6
Groove with top 3 cooperation of internal expanding.
The utility model workpiece is in the chuck body 2, when processing, moves up into clamp head 6, holds out against under internal expanding top 3
Clamp head 6, so that the workpiece 7 being mounted in clamp head 6 is compacted, internal expanding top 3 is fixed by adjusting bolt 4, then
Roll flute grinding wheel carries out Gear shape process.The utility model has abandoned traditional ringfeder structure, by internal expanding top 3 for chuck body 2
Hold out against, can to avoid the interference in worm abrasion wheel process, realize pinion gear workpiece fixation, guarantee roll flute processing when tooth
Guarantee within 0.01 range to spiral angular displacement, and the accumulative bounce of gear is within 0.01 range.
The utility model slightly changes the top size of internal expanding according to the design of the planetary gear of different inner diameters size, by adjusting interior
Rise and top adjustment bolt position or replaces holddown spring and can satisfy the needs of different workpieces processing, application and the quick letter of replacement
Just, practicability is very strong.
In addition, it should be noted that, all structure, feature and principles according to the utility model patent concept done it is equivalent
Variation or simple change, are included in the protection scope of the utility model patent.
