through the matching among the rotating shaft 505, the latch 509, the friction sleeve 18, the friction plate 17 and the discharging platform 7, the last section of transmission is used through the matching among the rotating shaft 505, the latch 509 and the friction sleeve 18, a plurality of clamping grooves are processed on the outer wall of the rotating shaft 505, the latch 509 can freely slide in the clamping grooves, and further the friction sleeve 18 can freely slide back and forth on the outer wall of the rotating shaft 505, no matter how the discharging platform 7 slides back and forth, the sliding capability and the rotation transmission of the latch 509 and the rotating shaft 505 can be ensured through the matching between the latch 509 and the rotating shaft 505, the discharging platform 7 can be started and stopped at any longitudinal position, and the problem that the stopping capability cannot be carried out when the discharging platform 7 longitudinally moves to any position is solved;
through the cooperation of the hydraulic cylinder 15, the rotating shaft 505, the latch 509, the first bevel gear 507, the second bevel gear 508, the Schmitt coupling 506 and the sleeve block 502, the internal structure of the coupling assembly 5 is a pure mechanical transmission structure, only the hydraulic cylinder 15 for triggering the limit capacity to start and stop needs electric control, and the use of a large number of mechanical transmission structures ensures that the numerical control machine tool has good transmission accuracy and reliability, is not easy to be easily damaged in the use environment of long-term vibration of the numerical control machine tool, and simultaneously, the hydraulic cylinder 15 which only needs electric control is directly exposed outside, so that the maintenance or the replacement is convenient, and the problem that the limit structure has short service life in the long-term vibration of the numerical control machine tool is avoided.
When the numerical control machine tool with the limiting protection structure is required to be used, the working principle is as follows:
and (4) normal processing:
firstly, a user can install and fix a milling machine clamp through a gully of the emptying platform 7, then the clamp can clamp and fix a workpiece, in the using process, the user can close the box cover 13 through the handle 9 and operate at the control panel 11, the left and right movement and the front and back movement of the emptying platform 7 can be controlled through the X-axis screw 405 and the Y-axis screw 303 through the positive and negative rotation of the X-axis motor 402 and the Y-axis motor 302, the height adjustment of the milling cutter structure 201 can be controlled through the positive and negative rotation of the Z-axis motor 202, after the corresponding height is reached, the power in the milling cutter structure 201 is started to rotate the milling cutter, and the milling machining of the workpiece can be completed through the left and right movement and the front and back movement of the emptying platform 7.
Limiting, protecting and processing:
usually, in the process of machining, a user needs to continuously complete workpiece replacement at the emptying platform 7, and at this time, the workpiece replacement needs to be performed without stopping the machine and opening the box cover 13, so that a situation that an operator is injured due to out-of-control milling cutter structure 201 caused by misoperation or system error may occur in the process of workpiece replacement, therefore, the invention designs a limit protection structure, that is, before the workpiece is replaced by opening the box cover 13, the output shaft of the hydraulic cylinder 15 needs to be controlled to extend out of the machine box through the control panel 11, so that the hydraulic cylinder 15 can push the emptying platform 7 to move upwards, at this time, the emptying platform 7 can drive the gear 19 to rotate through the vertical rack 16, and the gear 19 drives the horizontal rack 21 to drive the friction plate 17 to move, so that the friction plate 17 is tightly attached to the right end of the friction sleeve 18, the rotation of the friction sleeve 18 and the rotating shaft 505 is limited, and because the rotating shaft 505 has a transmission relationship with the Z-axis screw 207 through the coupling assembly 5, therefore, the rotation of the rotating shaft 505 is limited, namely the rotation of the Z-axis screw 207 is limited, the Z-axis screw 207 cannot rotate, namely the milling cutter structure 201 cannot change in height, even if the milling cutter structure 201 is out of control, the milling cutter structure 201 can only be fixed at a specific height and cannot move down to cause injury to an operator, sufficient time is reserved for the operator when misoperation or system errors occur to solve the problem, the possibility that the milling cutter structure 201 hurts people when the workpiece is replaced without shutdown is avoided, after the workpiece is replaced, the box cover 13 is closed, the material placing platform 7 is controlled by the hydraulic cylinder 15 to move downwards to reset, and the rotation limitation between the friction plate 17 and the friction sleeve 18 can be removed, so that the rotation capacity of the Z-axis screw 207 can be recovered.
Transmission of the coupling assembly:
the transmission of the coupling component 5 is firstly carried out by a 90-degree rotation reversing through a first bevel gear 507 and a second bevel gear 508, then is carried out by a Schmitt coupling 506, the Schmitt coupling 506 is matched with the sliding design of the upper sleeve block 502, so that the transmission of any position between two parallel shafts can be carried out in a certain range, therefore, no matter how the discharging platform 7 slides left and right, the Schmitt coupling 506 can ensure the rotation transmission capability of both ends, the discharging platform 7 can realize the start and stop of the limiting capability at any transverse position, the problem that the starting and stopping of the limiting capability cannot be carried out at any transverse position of the discharging platform 7 is avoided, the last section of transmission is used by matching among a rotating shaft 505, a latch 509 and a friction sleeve 18, the outer wall of the rotating shaft 505 is provided with a plurality of slots, and the latch 509 can freely slide in the slots, and then make the friction bush 18 can be slipped and guaranteed the transmission between the two freely in the front and back of the outer wall of the spindle 505, therefore no matter how the discharging platform 7 slips and slides back and forth, the cooperation between the latch 509 and the spindle 505 can guarantee its slip ability and rotation transmission, make the discharging platform 7 can realize the start and stop of the limiting ability of the invention in the longitudinal arbitrary position, avoid can't carry on the start and stop problem of the limiting ability in the discharging platform 7 longitudinal direction to arbitrary position, because the internal structure of the coupling assembly 5 is a pure mechanical transmission structure, only the hydraulic cylinder 15 used for triggering the start and stop of the limiting ability needs the electric control, the use of a large number of mechanical transmission structures makes the invention have good transmission accuracy and reliability, difficult to damage easily under the use environment of the long-term vibration of the numerically-controlled machine tool, at the same time only the hydraulic cylinder 15 needing the electric control is exposed outside directly, is convenient for maintenance or replacement, and avoids the problem that the limit structure has short service life when the numerical control machine tool vibrates for a long time.
