Description
Technical field
The utility model belongs to synchronizer technical field, specifically, in particular to a kind of be ground for synchronizer gear sleeve
The fixture of processing.
Background technique
Since synchronizer input shaft and output shaft are rotated with respective speed, there are one " synchronizations " to ask for conjunction when converting gear
Topic.Two different gears of rotation speed engage by force will necessarily occur impact, damage gear.Therefore, old-fashioned synchronizer
Gear shift to upshift and be stopped a moment in neutral position by the way of " bipod clutch ", downshift will in neutral position open out, with
Reduce the rotational speed difference of gear.But this operation is more complicated, it is difficult to grasp accurate.Therefore designer creates " synchronizer ", leads to
Crossing synchronizer makes that meshed gears will be wanted to reach consistent revolving speed and smoothly engage.
The component of reverse gear synchronizer includes tooth set, and annularly, tooth is on inner wall.It is different according to actual product standard, it needs
The thickness to cover to tooth is processed, and mainly carries out grinding by grinding machine.Tooth set is used as workpiece, and it is enterprising to be mounted on grinding machine
Row processing, need to clamp by fixture, existing fixture mostly be monomeric gripper, directly workpiece is clamped, install, adjust and
Disassembly, specificity is strong, poor universality, can not adapt to the requirement of multi items.
Utility model content
In view of the defect of the poor universality of the prior art, the technical problem to be solved by the utility model is to provide one kind
Fixture for synchronizer gear sleeve grinding.
Technical solutions of the utility model are as follows: a kind of fixture for synchronizer gear sleeve grinding, including cover for seat, described
The front end of cover for seat is provided with assembly cavity backward, and the assembly cavity is built-in with being provided with the folder with elastic opening that can be moved forward and backward
Tight tapered sleeve, the front periphery face of the clamping cone sleeve and the front of the assembly cavity form pre-large post-small cone match, described
The front of clamping cone sleeve is fitted with the workpiece collet with elastic opening；End face positioning has been bolted in the cover for seat
Part, the end face locating piece are located at the middle part of the clamping cone sleeve.
Using above technical scheme, cover for seat assembles the components such as clamping cone sleeve by setting assembly cavity, and clamping cone sleeve passes through
When entirety moves backward, using cone structure, so that the front of clamping cone sleeve is clamped to central reduction, and then setting is clamped
In workpiece collet above.The effect of end face locating piece is to guarantee workpiece in this vertical face when workpiece puts in
It is upper to keep smooth.When needing with changing workpiece description, the workpiece collet of inserting connection is only needed to change, replacement is just
Victory, it is applied widely, it is versatile.
Further, in order to be connected in cover for seat with helping end face locating piece firm stable, the middle part shape of the clamping cone sleeve
At step surface；Multiple via holes are evenly distributed on the step surface；The end face locating piece by pass through the via hole pin with
The cover for seat connection.
Further, in order to enable end face locating piece is fixedly connected, front-rear direction is provided with bolt on the pin and leads to
Hole.
Further, in order to be attached with the pull rod of grinding machine, rod head is provided in the middle part of the rear end of the clamping cone sleeve.
Further, in order to play perfect frame, and make structure more stable and safe during the work time, the cover for seat
Rear end face grinding machine spindle ring flange is installed.
Further, for the ease of disassembly, the workpiece collet is mounted on the front end face of the clamping cone sleeve by screw.
Further, in order to enable workpiece collet forms quick assembling-disassembling structure on clamping cone sleeve, the workpiece collet passes through
Arc strip wears the screw, and the perforation of arc strip is in size end structure, and big end can be passed through for the screw head.
The utility model has the advantages that the utility model it is novel, design rationally and convenient for operation, by the utility model to workpiece into
Row clamping grinding, for different workpiece, only needing replacing workpiece collet and end face locating piece every time can be adapted to not
Same specification and clamping requirement, compared with the existing technology, more adaptable, clamping, installation, adjustment and disassembly are all very convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is another structural schematic diagram of the utility model.
Fig. 3 is the A-A schematic cross-sectional view of Fig. 2.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
Such as a kind of Fig. 1 to fixture for synchronizer gear sleeve grinding shown in Fig. 3, there is cover for seat 1, after cover for seat 1
End face is equipped with grinding machine spindle ring flange 6.The front end of cover for seat 1 is provided with assembly cavity 1a backward, and assembly cavity 1a is built-in with being provided with
The rear end middle part of the clamping cone sleeve 2 with elastic opening that can be moved forward and backward, clamping cone sleeve 2 is provided with rod head 5.Clamping cone
The front periphery face of set 2 and the front of assembly cavity 1a form pre-large post-small cone match, and the front of clamping cone sleeve 2 is fitted with tool
The workpiece collet 4 of flexible opening, workpiece collet 4 are mounted on the front end face of clamping cone sleeve 2 by screw.Workpiece collet 4 passes through
Arc strip wears screw, and the perforation of arc strip is in size end structure, and big end can be passed through for screw head.In cover for seat 1
