Abstract
The invention discloses a pneumatic dividing device. A method of dividing rotation is designed according to a fluted disc ratchet wheel type, straight linear movement of an air cylinder is converted into rotation movement through a connection rod, the distance of movement of the air cylinder is limited to control a rotation angle of a fluted disc, equant teeth on the fluted disc serve as a ratchet wheel, and angle location is accurate. The air cylinder used for rotation dividing is applied to a locking mechanism simultaneously, a return trip of the air cylinder serves as rotation, pushing of the air cylinder serves as locking, and one air cylinder achieves two purposes. The pneumatic dividing device utilizing the air cylinder as power is clean, hygienic, free of auxiliary device noise, and sensitive to react, rotation and locating angles are accurate, the ingenious locking device of the pneumatic dividing device saves manufacturing cost, and the size of the whole device is reduced.
Description
Technical field
The present invention relates to minute manufacture fields such as calibration, relate in particular to a kind of pneumatic indexing means.
Background technology
Current drawing, for the machining of hex surface, is used general can 6 60 ° of Milling Process of dividing head rotation forming.The every rotation 1 of handle of dividing head turns chuck and can only rotate 9 °, so complete the calibration that six facing cuts of a part are cut, needs artificial rotary handle 40 to turn, and index time is long, and manual operation frequency is higher.
Vehicles Collected from Market adopts hydraulic separate scale, and hydraulic separate scale can meet the required precision of our current product completely, and reliable lock, but the shortcomings such as shortcoming is to have Hydraulic Station as auxiliary equipment, has noise, take up room, heat production.
Pneumatic indexing means can replace plain dividing head or hydraulic separate scale, pneumatic advantage is clean hygiene, without attachedly helping facility noise, be quick on the draw etc., but that shortcoming is pneumatic strength is little, the reliability of locking is also a very large problem.
Summary of the invention
The present invention, for solving the problems of the technologies described above, provides a kind of pneumatic indexing means, and it has manufacturing cost and the human cost of saving, reduces the advantages such as volume.
To achieve these goals, the present invention adopts following technical scheme.
A kind of pneumatic indexing means, comprise housing, cylinder, slide block, connecting rod, briquetting, ratchet, main shaft, described housing is surrounded by base plate, header board, cover plate, rear plate and side plate A and side plate B, described cylinder is connected with slide block through side plate A, described slide block is fixed on base plate, and can on base plate, slide, slide block is connected with connecting rod, connecting rod is connected with ratchet, briquetting is fixed on side plate B, and can on this side plate B, slide, on briquetting, being also provided with the locking boss contacting with the outer of ratchet, briquetting is also connected with cover plate by spring; Described ratchet be fixed on cover plate or and base plate on, ratchet center is provided with through hole, through hole coordinates with main shaft; Described main shaft is successively through header board, ratchet and rear plate; On described side plate A, be also provided with sour jujube piece, sour jujube piece is also provided with the locking jaw contacting with the outer of ratchet.
As a further improvement on the present invention, described main shaft coordinates with header board, rear plate by bearing.
Between described main shaft and header board, be also provided with sealing ring.
Described rear plate is provided with the adjustment lid of adjusting main spindle's.
Described base plate is provided with guide plate, anti-limited slip block play.
Between described cylinder and housing, be also provided with cushion block.
Described sour jujube piece is fixed on side plate A by sour jujube block.
Described ratchet by connecting plate and connecting plate fixed block be fixed on cover plate or and base plate on.
Described ratchet is also hinged with sour jujube frame.
On described side plate A, be also provided with reversal valve.
The first-selected mode of using fluted disc ratchet form to conceive calibration rotation of the present invention, rectilinear motion with cylinder, by connecting rod, be converted to and rotatablely move, the distance of restriction cylinder moving, in order to control the anglec of rotation of fluted disc, the decile tooth of usining again on fluted disc is as ratchet, accurate angle orientation, and rotation like this, calibration and location all complete.
Another key function of the present invention is locking, and coupling mechanism force is too little can affect part adds rigidity in man-hour, even can force part to rotate with main shaft because cutting force is excessive, causes part to be scrapped and damages lathe and cutter.Consider the volume of saving manufacturing cost, reducing device, the cylinder for rotary index is applied to retaining mechanism simultaneously, the backhaul of cylinder is as rotation, and the release of cylinder is as locking, and a cylinder is dual-purpose.End releasing action, according to four-bar linkage principle, is designed to hinge form by connecting rod, changes the component of angle in XY plane, makes original 120Kg be converted to 480Kg, and so, the problem of coupling mechanism force is solved by hinge shape.
Beneficial effect of the present invention: use cylinder pneumatic, clean hygiene, without attachedly helping facility noise, being quick on the draw; And the angle of rotation location is all very accurate, its cleverly locking device also saved manufacturing cost, reduced the volume of whole device.
