Description
Technical field
The utility model relates to a kind of chuck disengaging pawl mill bottom surface fixture.
Background technology
Chuck disengaging pawl formerly, its positioning reference plane is only provided with one, often there will be the large situation of error, and to adjust when occurring that error is larger and inconvenient in location.
Summary of the invention
Because prior art also exists the problems referred to above, the utility model proposes a kind of chuck disengaging pawl mill bottom surface fixture, it effectively can solve the problems referred to above of prior art.
The utility model solves the problem by the following technical programs:
A kind of chuck disengaging pawl mill bottom surface fixture, comprise: chuck disengaging pawl, it is located on sleeve, and is connected with support bar by spring in described sleeve, and the side of described chuck disengaging pawl is connected with compact heap by cylinder connecting rod, described cylinder connecting rod is connected with the second cylinder; Top board, its side connected with described chuck disengaging pawl is defined as the first positioning reference plane, and its lower plane is defined as the second positioning reference plane, described top board connects one first cylinder by a bar linkage structure, and this top board is covered by described first cylinder drivening rod structure or recessed the bottom surface of described chuck disengaging pawl; Described second cylinder can drive described compact heap to compress described chuck disengaging pawl and described first positioning reference plane close contact; When described top board is covered in described chuck disengaging pawl bottom surface, the spring stress compression between described support bar and described sleeve, makes the lower plane i.e. second positioning reference plane close contact of described chuck disengaging pawl and described top board.
The both sides of described chuck disengaging pawl are provided with base.
Described bar linkage structure is the parallel-crank mechanism be made up of connecting rod and rocking bar.
Described base is fixed with a fixed block, one end of described first cylinder is fixed on described fixed block by pin.
Described second cylinder is fixed on described base plate.
Owing to fixture of the present utility model being provided with two positioning reference planes, make location more accurate, error reduces; The precision of location can be adjusted easily by the assistance of the first cylinder and the second cylinder.
Accompanying drawing explanation
Fig. 1 is the structural representation of the first embodiment of the present utility model;
Fig. 2 is the structural representation of chuck disengaging pawl of the present utility model and top board.
Detailed description of the invention
Below in conjunction with detailed description of the invention, describe the present invention in detail.
See shown in Fig. 1 to Fig. 2.Fig. 1 is the structural representation of the first embodiment of the present utility model; Fig. 2 is the structural representation of chuck disengaging pawl of the present utility model and top board.
The chuck disengaging pawl mill bottom surface fixture of the present embodiment, comprising: chuck disengaging pawl, top board, the first cylinder and the second cylinder etc.Wherein,
Chuck disengaging pawl 1, it is located on sleeve 2, and is connected with support bar 3 by spring in described sleeve, and the side of described chuck disengaging pawl is connected with compact heap 5 by cylinder connecting rod 4, and described cylinder connecting rod is connected with the second cylinder 6;
Top board 7, its side connected with described chuck disengaging pawl is defined as the first positioning reference plane A, and its lower plane is defined as the second positioning reference plane B, described top board connects one first cylinder 8 by a bar linkage structure, and this top board is covered by described first cylinder drivening rod structure or recessed the bottom surface of described chuck disengaging pawl;
Described second cylinder can drive described compact heap to compress described chuck disengaging pawl and described first positioning reference plane A close contact; When described top board is covered in described chuck disengaging pawl bottom surface, the spring stress compression between described support bar and described sleeve, makes the lower plane i.e. second positioning reference plane B close contact of described chuck disengaging pawl and described top board.
Wherein, described bar linkage structure is the parallel-crank mechanism be made up of connecting rod 10 and rocking bar 11.It can coordinate the first cylinder to drive top board motion.
The both sides of described chuck disengaging pawl are provided with base 9, described base are fixed with a fixed block 12, and one end of described first cylinder is fixed on described fixed block by pin.Described second cylinder 6 is fixed on described base plate.
The method of work of the present embodiment:
1, clamps and school positioning reference plane: the fixture of the present embodiment is positioned on Grinder bench, beat the depth of parallelism of table adjustment first positioning reference plane A and Y-axis, the good main shaft emery wheel of reconditioning, start grinding machine spindle by fixture positioning reference plane 1 milled, ensure that fixture first positioning reference plane A and grinding machine Y-axis, the Z axis depth of parallelism perpendicularity of grinding machine spindle (namely with) are in technological requirement; Then the second positioning reference plane B is fixed, ensure that the second positioning reference plane B and grinding machine X-axis, the Y-axis depth of parallelism are in technological requirement.
2, clamping workpiece: chuck disengaging pawl is placed on stop sleeve, air pressure makes the first cylinder piston rod release, by linkage, top board is covered on disengaging pawl bottom surface, spring between support bar, sleeve produces elastic force by compression, makes disengaging pawl bottom surface and top board lower plane (the second positioning reference plane B) close contact.Then air pressure makes the second cylinder piston rod release, by cylinder connecting rod, compact heap compression chuck disengaging pawl (with the first positioning reference plane A close contact).Air pressure makes the first cylinder piston rod retract, and by linkage, top board is retracted into fixture back upper place (avoiding wheel grinding).
3, grind bottom surface and unload workpiece: starting main shaft and start to grind disengaging pawl bottom surface.Having ground rear air pressure makes the second cylinder piston rod retract, and takes off the disengaging pawl of firm milled.
4, next circulation: repeat process step 2,3,4.
Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
