Abstract

The invention belongs to the technical field of gear machining, and discloses a universal dividing head. The universal dividing head comprises a base, a dividing plate, a dividing fork, a side shaft, a worm falling handle, a main shaft locking handle, a rotating body, a main shaft, a graduated disc, a dividing handle and a positioning insertion pin. The universal dividing head is characterized in that a dividing handle shaft perpendicular to the main shaft is sleeved with the dividing plate, and the dividing fork and the dividing plate are coaxially fixed; a change gear is installed at the rear end of the dividing head main shaft, the main shaft locking handle is connected to the outer side of the main shaft, the dividing head main shaft is installed on the rotating body, and the graduated disc is fixed to the front end of the main shaft and rotates along with the main shaft. Multiple rings are arranged on the front face and the back face of the dividing plate, and positioning holes are evenly distributed in the circumference of each ring. The main shaft is a hollow shaft, and conical holes are formed in the front and back ends of the main shaft. The universal dividing head has the advantages of being convenient to operate, and the equal-division deviation of workpieces is small.

Description

A kind of universal dividing head
Technical field
The invention belongs to lathe accessory technical field, relate to application universal dividing head.
Background technology
Universal dividing head is a kind of indexed tool, is also mechanical dividing heads or is called for short dividing head.It is one of important accurate annex of milling machine.The lathes such as grinding machine, drilling machine, wound bed are also widely used.Dividing head can rotate the workpiece be clamped on top or chuck any angle also can carry out circumference graduation to workpiece.Make many machine components such as splined shaft, jaw clutch, straight spur gear etc. need the teeth groove of decile can milling on milling machine, meet the processing request of ultraprecision gear.
Summary of the invention
The present invention is intended to the defect overcoming prior art, provides a kind of universal dividing head, has easy to operate, the feature that decile workpiece deviation is little.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of universal dividing head, comprise pedestal 1, index dial 2, calibration fork 3, side shaft 4, worm screw come off handle 5, principal shaft locking handle 6, revolving body 7, main shaft 8, dial 9, dividing arm 10, index dial 2 is sleeved on dividing arm 10 axle vertical with main shaft, and calibration fork 3 is coaxially fixed with index dial 2; Change gear is installed by side shaft 4 in dividing head spindle 8 rear end, is connected with principal shaft locking handle 6 outside main shaft 8, and revolving body 7 installs dividing head spindle, and dial 9 is fixed on front-end of spindle and rotates together with main shaft 8.
Further, index dial positive and negative there are some circles, often enclose and be circumferentially evenly distributed with locating hole.
Further, main shaft is a hollow shaft, and its rear and front end is taper hole.
Compared with prior art, the present invention has following beneficial effect:
The present invention is easy to operate, and decile workpiece deviation is little, and workpiece can be made arbitrary circumference equal dividing or straight line and move apart from calibration, what realize workpiece meets feed motion.
Accompanying drawing explanation
Fig. 1 is the structural representation of universal dividing head of the present invention.
Fig. 2 is that schematic diagram is looked on a left side for universal dividing head of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Embodiment as shown in Figure 1, 2, a kind of universal dividing head, comprise pedestal 1, index dial 2, calibration fork 3, side shaft 4, worm screw come off handle 5, principal shaft locking handle 6, revolving body 7, main shaft 8, dial 9, dividing arm 10, index dial 2 is sleeved on dividing arm 10 axle vertical with main shaft, main shaft is a hollow shaft, and its rear and front end is taper hole.Calibration fork 3 is coaxially fixed with index dial 2; There are some circles positive and negative to index dial 2, often enclose and are circumferentially evenly distributed with locating hole.Change gear is installed by side shaft 4 in dividing head spindle 8 rear end, and worm screw comes off handle for throwing off the engagement of worm and wheel.Principal shaft locking handle 6 is connected with, for locking main shaft after calibration outside main shaft 8.Revolving body 7 installs dividing head spindle, and main shaft can rotate along the ring-shaped guide rail on pedestal with revolving body.Dial 9 is fixed on front-end of spindle and rotates together with main shaft 8.
Last it is noted that the foregoing is only explanation embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
