Circumference porous rotary work piece is evenly equipped with some holes in the circumferential; existing circumferential porous rotary work piece is often holed to it on common driller; holed by drill bit after drill chuck holding workpiece progressively rotates to an angle; Problems existing is; chuck is driven by motor, needs motor frequent start-stop in the process that chuck rotates a circle, and between each start and shutdown, the Angle ambiguity of chuck is difficult to reach requirement; often need manually to adjust chuck, operating efficiency is low.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of intermittent type rotation mechanism, workpiece circumference batch (-type) can be made to rotate, boring accurate positioning by this rotating mechanism.
Intermittent type rotation mechanism of the present utility model, comprise pedestal, the chuck that pedestal rotates and the transmission mechanism driving chuck gap to rotate, on described chuck, circumference is evenly equipped with multiple cylinder, angle between adjacent column is α, the slide block that described transmission mechanism is included in horizontal reciprocating movement on pedestal and the wedge be hinged on slide block, the inclined-plane of described wedge down, described slide block advances a stroke, the vertical end face of wedge promotes one of them cylinder and chuck is rotated, and rotational angle is α, when described slide block retreats, another cylinder contacts of the inclined-plane of wedge and the adjacent of foregoing cylindrical also upwards swings and slips over this cylinder.
Further, described chuck comprise coaxial arrange rotating shaft, disk and positioning sleeve, described rotating shaft one end is through pedestal and be rotatably assorted with pedestal, and the described rotating shaft other end is connected with disk, described disk is connected by cylinder with between positioning sleeve, and described positioning sleeve is by fixing for workpiece circumference.
Further, described slide block has vertical through holes, Horizontal limiting plate is provided with bottom described vertical through holes, described wedge is positioned at vertical through holes and one end is hinged by the hole wall of bearing pin and vertical through holes, the other end of described wedge has lapping plate, when wedge is positioned at lower limit position, lapping plate is overlapped on limiting plate.
Further, described slide block has horixmtal long hole, and described pedestal is provided with the gag lever post in order to limit slide block extreme position through horixmtal long hole.
The beneficial effects of the utility model: intermittent type rotation mechanism of the present utility model, comprise pedestal, the chuck that pedestal rotates and the transmission mechanism driving chuck gap to rotate, on described chuck, circumference is evenly equipped with multiple cylinder, angle between adjacent column is α, the slide block that described transmission mechanism is included in horizontal reciprocating movement on pedestal and the wedge be hinged on slide block, the inclined-plane of described wedge down, described slide block advances a stroke, the vertical end face of wedge promotes one of them cylinder and chuck is rotated, and rotational angle is α, when described slide block retreats, another cylinder contacts of the inclined-plane of wedge and the adjacent of foregoing cylindrical also upwards swings and slips over this cylinder.Wedge moves back and forth lower driving chuck intermittence at slide block and rotates, and each rotational angle of chuck is fixed, and can carry out circumference accurately location to workpiece, bore position precision is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is schematic perspective view of the present utility model;
Fig. 2 is generalized section of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in the figure: the intermittent type rotation mechanism of the present embodiment, the transmission mechanism 3 comprising pedestal 1, the chuck 2 that pedestal rotates and drive chuck gap to rotate.Chuck 2 holding workpiece is rotated on pedestal, concrete, chuck 2 comprise coaxial arrange rotating shaft 22, disk 23 and positioning sleeve 24, described rotating shaft 22 one end is passed pedestal and is rotatably assorted with pedestal 1, described rotating shaft 22 other end is connected with disk 23, and described disk 23 is connected by cylinder 21 with between positioning sleeve 24, and cylinder 21 quantity is multiple, and circumference is uniform on chuck 2, trade union college rotates with it on positioning sleeve 24.
In the present embodiment, on chuck 2, circumference is evenly equipped with 5 cylinders 21, angle between adjacent column is 72 °, the slide block 31 that described transmission mechanism 3 is included in horizontal reciprocating movement on pedestal and the wedge 32 be hinged on slide block, the inclined-plane of described wedge 32 down, described slide block 31 advances a stroke, the vertical end face of wedge 32 promotes one of them cylinder and chuck is rotated, and rotational angle is 72 °, namely the wedge angle that a stroke can make chuck rotate of often advancing is identical with the angle between adjacent column, and angle is all α.When described slide block 31 retreats, another cylinder contacts of the inclined-plane of wedge 32 and the adjacent of foregoing cylindrical also upwards swings and slips over this cylinder.
As the further improvement of technique scheme, described slide block 31 has vertical through holes 33, Horizontal limiting plate 34 is provided with bottom described vertical through holes 33, described wedge 32 is positioned at vertical through holes 33 and one end is hinged with the hole wall of vertical through holes 33 by bearing pin 35, the other end of described wedge 32 has lapping plate 36, when wedge is positioned at lower limit position, lapping plate 36 is overlapped on limiting plate 34, when wedge 32 retreats, the inclined-plane of wedge 32 and cylinder contacts, under cylinder effect, wedge 32 is put on bearing pin 35, wedge is movable to opposite side from cylinder side by inclined-plane, then wedge 32 is under gravity around the natural bottom of bearing pin 35, and be overlapped on limiting plate 34 by lapping plate 36, the now vertical end face of wedge 32 and cylinder contacts, continue to promote cylinder by its vertical end face when wedge advances and again rotate 72 ° to make chuck.
