Abstract
The utility model relates to a composite precision dividing head, belonging to a common dividing tool used in the works of milling, tongs and scribing. The utility model is characterized in that three precision index plates 1 type, 2 type and 3 type can be arranged at the position of an index plate of the existing dividing head in an alternation mode, and the precision index plate is composed of an index plate (1), a dial (2), a vernier (3) and an annular vernier seat (4). The precision index plate can be provided with a calculator which can not only raise the precision of the dividing head, but also improve the complicated degree of a computer, which causes general operators to easily master, and the utility model has the advantages of simple structure and easy manufacture.
Description
The utility model relate to a kind ofly mill, pincers, line work combined precision dividing head commonly used.
At present general universal dividing head is made up of main shaft, index dial, handle, alignment pin and pot wheel, worm screw, and 22 circle holes are arranged on index dial.Utilize these locating holes to calculate the workpiece rotational angle during calibration, precision can only reach 8 '-10 '.Just be difficult to reach accurate for the high workpiece of cutting precision and require and calculate loaded down with trivial detailsly, bring a lot of inconvenience, also be easy to make mistakes, be difficult for grasping to the operator.
The purpose of this utility model just provides a kind of improved dividing head, and it not only makes the precision of original dividing head be improved.And improved the complexity of calculating.And can be simultaneously and usefulness, be easy to grasp.
Dividing head, the other end that is connected worm gear (10), worm screw (9) worm screw by final drive shaft (11) links to each other with main shaft (7), and final drive shaft (11) other end is equipped with index dial (1), and handle (5), and an alignment pin (14) is arranged on the handle.
The characteristics of the combined precision dividing head of the utility model design are exactly on the index dial position of original dividing head, the precision index plate of three types on 1 type, 2 types, 3 types can be installed by turns, and precision index plate is toured around mark seat (4) by index dial (1) dial (2) vernier (3) garden and is formed.Index dial and dial are installed on the interior helical gear (13) of sleeve (12) by holding screw (16), and vernier can be fixed on the vernier seat by screw (18).The vernier seat can also be cast on the housing of dividing head and make whole combined precision dividing head, and handle (5) can pass through alignment pin (14) and drive dial (2) and rotate.Fixing when forwarding desired location to by screw (17).Since the speed ratio of dividing head be 1: 40 therefore main shaft change 360 °, the every circle of handle only changes 9 ° (promptly 540 '), divide on the combination precision index plate of being installed on the combined precision dividing head have 540 scales, every scale be 1 ', branch 60 scales on the vernier, every scale is
Therefore precision can reach 1 ".Need do timesharing such as Z when workpiece, then the per minute degree once, workpiece should change
Change, at this moment the revolution of handle is n,
Combined precision dividing head described in the utility model is owing to only need to install a combination precision index plate on original dividing head.Therefore simple in structure, manufacture conveniently, promptly improved the precision of original dividing head, simplified calculating again, make the user be easy to grasp.

Fig. 9 is 3 type precision index plate side views.
The precision index plate of being installed on the combined precision dividing head divides three kinds on 1 type, 2 types, 3 types.
Below elaborate:
As Fig. 2, shown in Figure 3, the index dial on the former dividing head is taken off.According to requirements of one's work, can be on the position of former index dial, the precision index plate of three types on 1 type, 2 types, 3 types is installed by turns, precision index plate is toured around mark seat (4) by index dial (1) dial (2) vernier (3) garden and is formed.Dial and index dial are installed by holding screw (16)
On the helical gear (13) in sleeve (12), vernier can be fixed on the vernier seat by screw (18).Handle (5) can pass through alignment pin (14) and drive dial (2) rotation.Fixing when forwarding desired location to by screw (17).
As Fig. 4, shown in Figure 5, the combined precision index dial that 1 type precision index plate is made up of index dial and dial.Be fixed on the interior helical gear (13) of sleeve (12) by screw (16) during use, can use on the two sides according to the need of work dial.
As Fig. 6, shown in Figure 7,2 type precision index plates be by the one side be that scale simultaneously is the precision index plate that the index hole two sides can both be used.Also can be made into one side is the precision index plate that the scale another side does not have index hole.During use, be installed on the interior helical gear (13) of sleeve (12) by holding screw (16).
As Fig. 8, shown in Figure 9,3 type precision index plates are slim precision index plates, can be installed on the former index dial by holding screw (16) during use.
During use at first with the calibration loop on the combined precision dividing head spindle (8) zero set, five equilibrium according to workpiece requires to have calculated calibration, swing dividing arm (5) then and aim at calibration and require desired location, tighten holding screw (17) and both can machine precision index plate is fixing.
