Abstract
A clamp pressure fine-adjustment device for a surface lapping machine comprises a main shaft rotary disk (1). The center of the main shaft rotary disk (1) is coaxially connected with a station main shaft (2), and an outer casing (3) is sleeved on the station main shaft (2). The clamp pressure fine-adjustment device is characterized in that a guide sliding key (12) is assembled between the outer casing (3) and the station main shaft (2); a clamp body (9) is fixedly connected with a clamp connecting part (10) through a first sunk screw (6); the clamp connecting part (10) is fixedly connected with the outer casing (3) through a second sunk screw (5); a clamp main shaft (11) is fixedly connected with the clamp connecting part (10) through a third sunk screw (8) and used for limiting rotation of the clamp connecting part (10) under the action of a cylindrical pin (7); the station main shaft (2) and the clamp main shaft (11) are integrally connected through an adjusting nut (4) connected with a handle (13); and the screw pitch of the adjusting but (4) is different from that of the third sunk screw (8). By using differential screw structure, the clamp pressure fine-adjustment device realizes fine adjustment of pressure exerting on workpieces. Moreover, the structure after adjustment is capable of self-locking, and needs no further fastening and positioning operation.
Description
Technical field
The utility model relates to a kind of pressure micromatic setting, especially face lapping mill chucking pressure micromatic setting.
Background technology
In the multistation face lapping mill, the grinding pressure on the workpiece is provided by abrasive disk rising contact workpiece, and this has just produced a problem: can not guarantee that the workpiece grinding pressure on a plurality of stations is identical.If the initial pressure the when workpiece on each station grinds is different, when grinding a collection of workpiece substandard products will appear so.If want to process the different workpiece of Grinding Quality in a process of lapping, depending merely on the abrasive disk rising is impossible realize.So need on each station, design a cover pressure micromatic setting, to address the above problem.
Summary of the invention
For these reasons, the purpose of this utility model is to provide a kind of pressure micromatic setting of face lapping mill, and it can realize that workpiece moves up and down within the specific limits.
The utility model proposes a kind of face lapping mill chucking pressure micromatic setting, it comprises a main shaft gyration dish 1, the center of main shaft gyration dish 1 and 2 coaxial linking to each other of station main shaft, be set with shell 3 on the station main shaft 2, it is characterized in that, be equipped with guiding feather key 12 between shell 3 and the station main shaft 2, clamp body 9 is affixed by first sunk screw 6 (4 uniform) and anchor clamps connector 10, anchor clamps connector 10 is affixed by second sunk screw 5 (3 uniform) and shell 3, anchor clamps main shaft 11 is affixed with anchor clamps connector 10 by the 3rd sunk screw 8, the rotation of restriction anchor clamps connector 10 under the effect of straight pin 7 again, by adjusting nut 4 station main shaft 2 and anchor clamps main shaft 11 are linked together, adjusting nut 4 is connected with handle 13, and adjusting nut 4 is different with the pitch of the 3rd sunk screw 8.
Face lapping mill chucking pressure micromatic setting of the present utility model utilizes the differential screw structure to realize being applied to the fine setting of the pressure on the workpiece, and this structural adjustment can also self-locking after intact, needn't carry out the clamping and positioning operation again.When two right-handed threads, one side pitch is a, opposite side pitch is b, and (just the moved up distance of a-b of a＞when b) adjusting nut 4 counterclockwise (seeing from top to bottom) rotates a circle, shell 3 relative station main shafts, vice versa.For example work as a=1.5mm, during b=1mm, adjusting nut 4 shell 3 a-b=1.5-1=0.5mm that just makes progress away that turns around counterclockwise, vice versa.So just realize micro-adjusting, thereby changed the active force between workpiece and the abrasive disk.
Description of drawings
Fig. 1 is the structural front view of face lapping mill chucking pressure micromatic setting of the present utility model;
Fig. 2 is the structure vertical view of face lapping mill chucking pressure micromatic setting of the present utility model.
Specific embodiments:
Referring to Fig. 1 and Fig. 2, the overall positions of face lapping mill chucking pressure micromatic setting of the present utility model relation: whole micromatic setting is fixed on the multi-station turning dish 1, link to each other with main shaft by the rotary disk center, thus the transmission of realization power.
Concrete micromatic setting position relation: the center of main shaft gyration dish 1 and 2 coaxial linking to each other of station main shaft, be set with shell 3 on the station main shaft 2, be equipped with guiding feather key 12 between shell 3 and the station main shaft 2, clamp body 9 is affixed by first sunk screw 6 (be preferably 4 uniform) and anchor clamps connector 10, anchor clamps connector 10 is affixed by second sunk screw 5 (be preferably 3 uniform) and shell 3, anchor clamps main shaft 11 is affixed by one the 3rd sunk screw 8 and anchor clamps connector 10, the rotation of restriction anchor clamps connector 10 under the effect of straight pin 7 again, by adjusting nut 4 station main shaft 2 and anchor clamps main shaft 11 are linked together, adjusting nut 4 is connected with handle 13, and adjusting nut 4 is different with the pitch of the 3rd sunk screw 8.
Face lapping mill chucking pressure micromatic setting of the present utility model utilizes the differential screw structure to realize being applied to the fine setting of the pressure on the workpiece, and this structural adjustment can also self-locking after intact, needn't carry out the clamping and positioning operation again.When two right-handed threads, one side pitch is a, opposite side pitch is b, and (just the moved up distance of a-b of a＞when b) adjusting nut 4 counterclockwise (seeing from top to bottom) rotates a circle, shell 3 relative station main shafts, vice versa.For example as the pitch a=1.5mm of adjusting nut 4, during the pitch b=1mm of the 3rd sunk screw 8, adjusting nut 4 shell 3 a-b=1.5-1=0.5mm that just makes progress away that turns around counterclockwise, vice versa.So just realize micro-adjusting, thereby changed the active force between workpiece and the abrasive disk.
When turning handle 13, it just drives adjusting nut 4 rotations, and whole device will axially slide up and down at the effect lower edge main shaft of guiding feather key 12, has so just realized fine setting.Because the maximum grinding pressure on each workpiece is about 1570N, and workpiece move up and down distance when very little grinding pressure alter a great deal, this just requires the pressure-regulating device adjustable range very little, the scope of adjusting can meet the demands in 2mm.
