Description
Technical Field
The utility model relates to a tip device for aligning large-sized barrel parts, and belongs to the technical field of machining.
Background
In the process of machining large-sized barrel parts, the problem that the center hole of a workpiece is not matched with the center of a machine tool often exists, the matched center needs to be replaced, and sometimes even the center matched with the center hole of the workpiece needs to be manufactured again. The center is replaced for about 1 hour, and the manufacturing period is longer; in the actual processing process, the processing period of the workpiece is often prolonged due to the long manufacturing period of the center, and the normal working progress is delayed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a centre device for aligning large-sized barrel parts, which is used for solving the problems.
In order to achieve the purpose, the utility model adopts the technical scheme that:
a centre device for aligning large-scale barrel parts comprises a machine tool centre and a centre taper sleeve fixedly connected with the machine tool centre through a jackscrew; the center taper sleeve comprises a center taper sleeve B surface matched with the center of the machine tool and a center taper sleeve A surface matched with the central hole of the workpiece, and the center taper sleeve B surface and the center taper sleeve A surface are coaxial; the connecting end of the tip taper sleeve and the machine tool tip is also provided with a threaded hole matched with the jackscrew for use.
The technical scheme of the utility model is further improved as follows: the threaded holes are 4 and are uniformly distributed in the circumferential direction of the tip taper sleeve.
The technical scheme of the utility model is further improved as follows: the jackscrew is M12 jackscrew.
The technical scheme of the utility model is further improved as follows: the coaxiality of the surface B of the tip taper sleeve and the surface A of the tip taper sleeve is less than 0.01 mm.
The technical scheme of the utility model is further improved as follows: the length and the size of the tip taper sleeve are adjustable.
Due to the adoption of the technical scheme, the utility model has the following technical effects:
the center manufacturing method is simple to manufacture and convenient to use, effectively avoids the problems of center replacement and re-manufacturing, saves the center replacement time and manufacturing cost, and solves the problem that the center manufacturing period does not meet the workpiece processing period.
The utility model has the function of tip angle conversion through the two conical surfaces of the tip taper sleeve, so that the tip angle is consistent with the angle of the central hole of the workpiece.
The utility model converts the size of the big end of the centre into the size of the centre taper sleeve, and can be suitable for the opening size of different central holes of a workpiece by adjusting the size of the centre taper sleeve, thereby achieving the purpose of expanding the application range of the centre.
According to the utility model, the effect of adjusting the length of the center can be achieved by adjusting the length of the center taper sleeve, so that the problem of interference between a workpiece and a machine tool caused by too short length of the center is solved.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the structure of the tip taper sleeve of the present invention;
FIG. 3 is a schematic structural diagram of the present invention in application;
the machining center comprises 1 a machine tool center, 2 a jackscrew, 3 a center taper sleeve, 3-1 a center taper sleeve surface A, 3-2 a center taper sleeve surface B, 3-3 a threaded hole, 4 and a workpiece.
Detailed Description
The utility model is described in further detail below with reference to the following figures and specific examples:
a centre device for aligning large-sized barrel parts is shown in figure 1 and comprises a machine tool centre 1 and a centre taper sleeve 3 fixedly connected with the machine tool centre 1 through a jackscrew 2, wherein the jackscrew 2 is preferably an M12 jackscrew. As shown in figure 2, the tip taper sleeve 3 comprises a tip taper sleeve B surface 3-2 matched with the machine tool tip 1 and a tip taper sleeve A surface 3-1 matched with a central hole of a workpiece 4, and the coaxiality of the tip taper sleeve B surface 3-2 and the tip taper sleeve A surface 3-1 is less than 0.01mm, so that the precision requirement when the reference of the machine tool tip 1 is converted to the tip taper sleeve A surface 3-1 in use is guaranteed. The connecting end of the center taper sleeve 3 and the machine tool center 1 is further provided with threaded holes 3-3 matched with the jackscrews 2 for use, in order to prevent the center taper sleeve 3 from falling off from the machine tool center 1, the number of the threaded holes 3-3 is preferably 4, and the threaded holes are uniformly distributed in the circumferential direction of the center taper sleeve 3. The length dimension of the tip taper sleeve 3 can be adjusted according to requirements.
As shown in fig. 3, when the tool center is applied, a proper center taper sleeve 3 is selected according to the size of a center hole of a workpiece 4 and the size of a machine tool center 1, a B surface 3-2 of the center taper sleeve is attached to the machine tool center 1 and is fixed by a jackscrew 2, and an A surface 3-1 of the center taper sleeve is attached to the center hole of the workpiece 4, so that the size of the large end of the machine tool center 1 is converted into the size of the center taper sleeve 3, and the reference of the machine tool center 1 is converted into the A surface of the center taper sleeve, so that the purpose of expanding the application range of the center is achieved.
In addition, the utility model can achieve the effect of adjusting the length of the center by adjusting the length size of the taper sleeve of the center, thereby solving the problem of interference between a workpiece and a machine tool caused by the over-short length of the center.
