Description

Technical Field

[0002] Machining refers to the process of changing the external dimensions or performance of a workpiece through a mechanical device. During the processing of the workpiece by the machining center equipment, a clamping mechanism is required to fix the workpiece.

[0003] The existing technical authorization announcement number CN210024520U patent document provides a workpiece fixing fixture for axial deep hole rotary drilling. The advantages of this utility model are: while the spindle drill bit of the drilling machine rotates at high speed to drill the axial deep hole, the cylinder body rotates at low speed around the center of the axis of the processed hole, making it difficult for the axis of the drilled hole to be skewed and cause wall penetration, thereby improving the qualified rate.

[0004] However, when the existing rotary floating clamping mechanism used in the machining center is used, it is not convenient to buffer the impact force generated during the equipment processing. The existing rotary floating clamping mechanism can only play a single positioning effect on the workpiece. During the processing of the workpiece by the machining center equipment, a certain impact force will be generated. If it is not buffered, it will easily cause the workpiece to shake, which will directly affect the processing accuracy and processing quality of the workpiece, and it is not convenient to meet people's usage needs.

When using the clamping mechanism to clamp the workpiece, the staff places the base 1 on the workbench of the machining center equipment and adjusts it to a position suitable for processing, so that the rotation center of the rotating gear disc 401 on the processing seat 2 corresponds to the spindle center of the machining center equipment, and then uses a fastening structure (not shown in the figure) to fix the base 1. The staff places the processed workpiece on the friction pad 604 on the rotating gear disc 401, and makes the workpiece located in the middle of the clamping plate 407. The friction pad 604 increases the friction force of the contact surface between the workpiece and the rotating gear disc 401.

The staff can perform processing operations on the workpiece by operating the machining center equipment, and the rotary motor 602 drives the driving gear disc 603 to rotate, and the driving gear disc 603 drives the rotary gear disc 401 to rotate, thereby driving the processed workpiece to rotate along the rotation center of the rotary gear disc 401 to meet the processing requirements of the workpiece.

[0028] Working principle: When using the clamping mechanism to clamp the workpiece, the staff places the base 1 on the workbench of the machining center equipment and adjusts it to a position suitable for processing, so that the rotation center of the rotary gear disk 401 on the processing seat 2 corresponds to the spindle center of the machining center equipment, and then uses a fastening structure (not shown in the figure) to fix the base 1. The staff places the processed workpiece on the friction pad 604 on the rotary gear disk 401, and makes the workpiece located in the middle of the clamping plate 407. The friction pad 604 increases the friction force of the contact surface between the workpiece and the rotary gear disk 401. The staff drives the moving block 504 to move on the screw rod 503 by operating the adjustment motor 502. The moving block 504 drives the No. 2 chuck 505 to move up and down and adjusts it to a position suitable for the length of the workpiece. Then the staff operates the clamping motor 404 to make the two sets of clamping slides 406 move on the bidirectional screw The upper and lower parts 405 move in opposite directions, and the clamping slider 406 drives the clamping plate 407 to move in opposite directions, so that the clamping plate 407 is in full contact with the workpiece, thereby realizing the positioning and clamping of the workpiece and ensuring the stability of the workpiece clamping. The staff can perform processing operations on the workpiece by operating the machining center equipment. During the processing of the workpiece, the spindle processing structure of the machining center equipment brings a certain impact force to the workpiece. The shock absorber 301 uses its energy absorption characteristics to buffer the impact force exerted on the machining seat 2. Under the support of the plug-in column 302 and the plug-in seat 303, the machining seat 2 is guided and supported to reduce the shaking of the machining seat 2 caused by external force, thereby ensuring the stability of the workpiece during processing. The rotary motor 602 drives the driving gear disc 603 to rotate, and the driving gear disc 603 drives the rotary gear disc 401 to rotate, thereby driving the processed workpiece to rotate along the rotation center of the rotary gear disc 401 to meet the processing requirements of the workpiece.
