Abstract
The invention relates to a high-efficiency fixture for drilling press fit holes in a large-tonnage ball socket. The high-efficiency fixture comprises a fixture body, a flange shaft and a manual self-centering chuck; the manual self-centering chuck is fixed to a flange plate of the flange shaft through a bolt. The high-efficiency fixture has the advantages that the large head of the ball socket faces downwards manually or mechanically, the ball socket is conveyed upwards and is clamped by the chuck, workpiece clamping time can be saved in production and waiting time can be reduced to a great extent; moreover, when the large ball socket is machined, a common chuck can meet the clamping requirement, and a large chuck is not required to be specially purchased; a motor drives a driving pulley to rotate, the driving pulley drives a driven pulley through a belt, a drum also rotates because the driven pulley is in key connection with the drum, the chuck is finally driven to rotate, a workpiece can also rotate, and as a drill bit and the workpiece rotate simultaneously as main movement, the coaxiality is high when the press fit holes are drilled, and the deviation of the drilled holes is avoided.
Description
Technical field
The present invention relates to a kind of High efficient clamp, especially a kind of large-tonnage ball-and-socket the pressure of the drill connects hole High efficient clamp and method thereof.
Background technology
At present, when processing the crimping hole of ball-and-socket, because ball-and-socket one end diameter is larger, need the chuck size of clamping ball-and-socket larger, need when clamping claw opening to open greatly, when clamping workpiece, need the stroke of chuck jaws to be moved back often the major part of ball-and-socket could be loaded into, waste time and energy during clamping, when starting to add man-hour, because the size of chuck is large, weight is large, chuck from turn to the start-up time that smooth rotation needs about 3min, the time that workman waits for is longer; When the pressure of the drill connects hole, by drill bit to workpiece feeding, if tool setting is not aimed at or inside workpiece uneven microstructure internal stress, easily there is larger deviation in boring, and the degree of depth of boring is larger, and deviation is larger.Therefore, just must develop and a kind ofly can raise the efficiency and reduce High efficient clamp and the method thereof of borehole throw, through retrieval, not find the same or analogous devices and methods therefor with the present invention.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly can raise the efficiency and reduce High efficient clamp and the method thereof of borehole throw.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of large-tonnage ball-and-socket the pressure of the drill connects hole High efficient clamp, and its innovative point is: comprise
One clamp body, this clamp body has the through cavity of a vertical direction, has the step surface of a block bearing assembly in the middle part of this cavity, and this step surface is placed with bearing assembly;
One flange shaft, this flange shaft is the axis body of a flanged dish in top, and axis body and ring flange central coaxial are provided with the centre bore holding large-tonnage ball-and-socket small end and pass through; Described flange shaft is arranged in the cavity of clamp body by bearing assembly, and the axis body bottom of flange shaft is connected with drive motors by belt transmission;
One manual self-centering chuck, this manual self-centering chuck is bolted on the ring flange of flange shaft.
Further, described fixture also comprises an annular upper end lid, and this annular upper end lid to be bolted on ring flange and to be positioned at bottom manual self-centering chuck.
Further, be provided with a drill bit directly over described clamp body, drill bit and cavity are coaxially arranged.
Further, described drill bit is indexable staight shank shallow hole drilling.
A kind of method adopting described fixture processing large-tonnage ball-and-socket the pressure of the drill to connect hole, its innovative point is: by the back side of ball-and-socket from fixture, ball-and-socket major part passes down through manual self-centering chuck clamping, and drive ball-and-socket to rotate with the rotating speed of 240r/min by drive motors, have one to rotate the drill bit of contrary still coaxial rotating with ball-and-socket directly over ball-and-socket simultaneously, its rotating speed is 100r/min ~ 250r/min, subsequently drill bit come downwards to ball-and-socket afterbody start boring.
The invention has the advantages that: apparatus of the present invention are passed through by ball-and-socket artificial or machinery is large upside down, then upwards carry and clamped by chuck, the clamping workpiece time can be saved aborning, and the stand-by period can be reduced significantly, and when machining large ball-and-socket, general chuck also can meet clamping requirement, and without the need to purchasing large-scale chuck specially;
By driven by motor driver pulley rotation, drive pulley is by belt drive driven pulley, because driven pulley is connected by key with rotating cylinder, so rotating cylinder also rotates, the final chuck that drives also rotates, and workpiece also can rotate, rotate as main motion owing to adopting drill bit and workpiece simultaneously, it is that axiality is high that the pressure of the drill connects hole, and avoid the phenomenon that deviation appears in boring, yield rate is very high;
The relative normal drill bit of indexable staight shank shallow hole drilling is compared linear velocity and can be reached 80m/s, and drilling efficiency can be made to improve 2 ~ 3 times.
Accompanying drawing explanation
Fig. 1 is the structural representation that apparatus of the present invention large-tonnage ball-and-socket the pressure of the drill connects hole High efficient clamp.
Detailed description of the invention
A kind of large-tonnage ball-and-socket the pressure of the drill as shown in Figure 1 connects hole High efficient clamp, comprises clamp body, flange shaft 3, manual self-centering chuck.
Clamp body has the through cavity 1 of a vertical direction, there is in the middle part of this cavity 1 step surface of a block bearing assembly 2, this step surface is placed with bearing assembly 2, flange shaft 3 is the axis body of a flanged dish in top, and axis body and ring flange central coaxial are provided with the centre bore holding large-tonnage ball-and-socket small end and pass through; Described flange shaft 3 is arranged in the cavity 1 of clamp body by bearing assembly 2, the axis body bottom of flange shaft 3 is connected with drive motors by belt transmission, manual self-centering chuck is bolted on the ring flange of flange shaft 3, ring flange has one group and is distributed in the end cap connecting hole that chuck connecting hole on disk body and a group are distributed in chuck connecting hole periphery ringwise ringwise, fixture also comprises an annular upper end lid 5, and this annular upper end lid 5 to be bolted on ring flange and to be positioned at bottom manual self-centering chuck.
Be provided with a drill bit directly over apparatus of the present invention clamp body, drill bit and cavity 1 are coaxially arranged, and drill bit is indexable staight shank shallow hole drilling, and indexable staight shank shallow hole drilling is here only exemplary effect certainly, can also be the drill bit of other models.
