Abstract
The utility model discloses a precision indexing device of a tyre mould electric spark formation machine tool, which is composed of a chuck, a bearing, a servo motor and a code device, wherein, the chuck which is fixed at the front of a main shaft and is driven to rotate by the main shaft grips the tyre mould blank; the bearing supports the main shaft and determines the rotating center of the main shaft; the servo motor drives the main shaft to rotate; the code device arranged on the tail end of the main shaft is connected to the main shaft, and is used for measuring the relative angular displacement of the main shaft. The code device is fixed coaxially to the back end of the main shaft by a rigid coupling. The main shaft bears the weight of the code device. The shell of the code device is connected to a bed piece by an anti-rotation slice. Because the code device is directly connected to the main shaft, and the anti-rotation slice only prevents the shell of the code device from rotating and does not bear the weight of the code device, the axiality of the code device and the main shaft is guaranteed. Thus, the utility model avoids the phenomenon that the main shaft has inaccurate graduation, blocked rotation, heating and even damage on the sophisticated code device due to the out-of-tolerance axiality.
Description
Affiliated field
The utility model relates to the precision dividing apparatus that a kind of machining tool is used.
Background technology
Process special-purpose EDM shaping machine for the wheel loose tool, the indexing accuracy of wheel loose tool circumference decorative pattern depends on the spindle index precision of lathe, therefore in order to improve the indexing accuracy of main shaft, the mode of having taked on main shaft, to install accurate encoder that has, its mounting means is that the pedestal with accurate encoder is installed on the body of make-up machine, and links together by shaft coupling and main shaft.Owing to be difficult to solve the axiality problem of main shaft and accurate encoder, cause that spindle index is inaccurate, rotation is obstructed, is generated heat or even the damage of accurate encoder.
Summary of the invention
The purpose of this utility model provides a kind of precision dividing apparatus of wheel loose tool EDM shaping machine of accurately calibration, by changing the connected mode of accurate encoder and main shaft, be able to the purpose that guarantees that the two is concentric, thereby guarantee the indexing accuracy of main shaft, and fundamentally solve because the spindle index that the two decentraction causes is inaccurate, rotation is obstructed, is generated heat or even the problem of the damage of accurate encoder.
For achieving the above object, the technical solution of the utility model is: the precision dividing apparatus of wheel loose tool EDM shaping machine, comprise the chuck that is arranged on front-end of spindle and takes turns the loose tool blank by the clamping of main shaft driven rotary, the bearing at supports main shaft and definite main shaft gyration center, drive the servomotor of main axis rotation, the encoder that is used to measure the main shaft relative angular displacement that is positioned at the main shaft tail end and is connected with main shaft, described encoder is fixed on the rear end of main shaft coaxially by rigid coupling, by the weight of main shaft carrying encoder, the shell of encoder is fixedlyed connected with lathe bed by anti-rotation device.
Owing to adopt technique scheme, the precision dividing apparatus of wheel loose tool EDM shaping machine, comprise the chuck that is arranged on front-end of spindle and takes turns the loose tool blank by the clamping of main shaft driven rotary, the bearing at supports main shaft and definite main shaft gyration center, drive the servomotor of main axis rotation, the encoder that is used to measure the main shaft relative angular displacement that is positioned at the main shaft tail end and is connected with main shaft, described encoder is fixed on the rear end of main shaft coaxially by rigid coupling, by the weight of main shaft carrying encoder, the shell of encoder is fixedlyed connected with lathe bed by anti-rotation device; Because encoder is directly installed on the main shaft, and anti-rotor only plays a part to prevent the encoder housing rotation and the weight of not carrying encoder, guaranteed the axiality of encoder and main shaft, the phenomenon generation of being obstructed, generating heat even damaging accurate encoder is forbidden, rotated to the spindle index of having avoided causing because of axiality is overproof.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in drawings, the precision dividing apparatus of wheel loose tool EDM shaping machine comprises the chuck 1 that is arranged on main shaft 3 front ends and is taken turns the loose tool blank by the clamping of main shaft 3 driven rotary, the bearing 2 of supports main shaft 3 and definite main shaft 3 centres of gyration, drive the servomotor 7 of main shaft 3 rotations, the encoder 6 that is used to measure the main shaft relative angular displacement that is positioned at main shaft 3 tail ends and is connected with main shaft 3, described encoder 6 is fixed on the rear end of main shaft 3 coaxially by rigid coupling, by the weight of main shaft 3 carrying encoders 6, the shell of encoder 6 is fixedlyed connected with lathe bed 8 by anti-rotor 5.Servomotor 7 drives gear wheel 8 rotations of being fixed on the main shaft 3 by the pinion 9 that is fixed on its output shaft.
The effect of encoder 6 is the relative angular displacements that are used to measure main shaft, and information passed to servomotor 7, control the accurate calibration rotation of main shaft 3, encoder is directly installed on the main shaft simultaneously, and anti-rotor only plays a part to prevent the encoder housing rotation and the weight of not carrying encoder, guaranteed the axiality of encoder and main shaft, the phenomenon generation of being obstructed, generating heat even damaging accurate encoder is forbidden, rotated to the spindle index of having avoided causing because of axiality is overproof.
