Description

Technical Field

[0001] The utility model relates to the technical field of vertical lathes, in particular to a lifting and lowering mechanism of a vertical lathe. Background Art

[0002] The difference between a vertical lathe and an ordinary lathe is that its spindle is vertical, which is equivalent to standing an ordinary lathe upright. Since its workbench is in a horizontal position, it is suitable for processing heavy parts with large diameters and short lengths. The vertical lathe can process internal and external cylinders, conical surfaces, end planes, grooves, chamfers, etc., and the clamping and correction of the workpiece are relatively convenient. The tool holder loaded on the vertical lathe is heavy, so the tool holder's carrying and operating device has high requirements. The operating device generally includes a horizontal displacement mechanism and a lifting displacement mechanism, which are used to drive the tool holder's carrier to move horizontally and vertically, so as to match the position of the load-bearing workpiece on the vertical lathe. In the existing technology, when the worktable of the lathe relies solely on the screw rod assembly at the slide rail seat to drive the worktable, the screw rod assembly at the slide rail seat will be subjected to the load during the operation of the worktable for a long time, which will cause wear of its own structure, thereby affecting the stable operation of the double-column vertical lathe. Therefore, it is necessary to use the force distribution suspension of the suspension mechanism to reduce the load force on the screw rod and the rod sleeve at the slide rail seat, and to apply an auxiliary force to the operation of the lifting mechanism to avoid the load on the drive motor caused by the excessive weight of the adjustment assembly when the drive motor is working. However, in the process of the suspension mechanism retracting and releasing the rope, it is easy to cause the suspension rope to become messy when it is wound on the winding wheel, which makes the suspension rope easy to become knotted, affecting the subsequent suspension work.

[0003] For example, Chinese patent CN217727852U discloses a double-column vertical lathe with high stability, including a column frame, a slide rail seat and a workbench, and also includes a suspension mechanism and a supporting mechanism. The suspension mechanism is composed of a mounting plate, a suspension seat, a winding roller, a coupling, a motor, a suspension rope and an ear plate. The slide rail seat is symmetrically fixed on the vertical frame surface of the column frame, and the workbench is installed at the seat groove of the slide rail seat with a screw rod and a rod sleeve. The mounting plate is detachably connected to the top surface of the column frame above the middle part of the workbench body, and a suspension mechanism is arranged between the workbench body itself and the column frame above it.

[0004] The double-column vertical lathe has the following disadvantages: although the load force on the screw rod and the rod sleeve at the slide rail seat is reduced by means of the force distribution suspension of the suspension mechanism, the service life of the screw rod and the rod sleeve at the slide rail seat is increased to ensure that the double-column vertical lathe can operate stably for a long time, however, in the process of the suspension mechanism retracting and releasing the rope, it is easy for the suspension rope to become messy when it is wound on the winding wheel, causing the suspension rope to easily become tangled, affecting the subsequent suspension work.

[0026] According to an embodiment of the utility model, a lifting and operating mechanism of a vertical lathe is provided.

[0027] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods.

Slide blocks 4 are sleeved on the outer circumference of the threaded rod 3. In specific applications, threaded holes matching the threaded rod 3 are opened on the top of the slide blocks 4, which are not shown in the figure. An adjusting component 5 is arranged on one side of the slide blocks 4, and a suspension component 6 matching the adjusting component 5 is arranged between the tops of the two column frames 2. A three-jaw chuck body 7 matching the adjusting component 5 is arranged on the other side of the top of the vertical lathe machine base 1, and a control panel 8 is arranged on one side of the vertical lathe machine base 1.

[0028] In addition, the working principles and structures of the three-jaw chuck body 7, drive motor 9, servo motor 1 502, servo motor 2 507, servo motor 3 5011, tool 5012 and servo motor 4 606 are all prior art and will not be elaborated in detail here.

[0029] With the help of the above technical scheme, the utility model has a reasonable and reliable structure and is easy to operate. It can not only perform automatic adjustment processing on the workpiece in the horizontal and vertical directions, but also quickly and conveniently retract and release the suspension rope 604, thereby reducing the load force on the slider 4 and the threaded rod 2 503, thereby improving the working efficiency of the lifting and running mechanism of the vertical lathe.

[0030] In one embodiment, for the above-mentioned adjustment component 5, the adjustment component 5 includes a concave frame 501 arranged on one side of the slider 1 4, a servo motor 1 502 is penetrated at one end of the concave frame 501, a threaded rod 2 503 is connected to the output end of the servo motor 1 502, a slider 2 504 is sleeved on the circumference of the threaded rod 2 503, and both ends of the slider 2 504 are interspersed with a limit rod 1 505 matched with the concave frame 501, a mounting shell 506 is arranged on one side of the slider 2 504, a servo motor 2 507 is arranged at the middle of the top of the mounting shell 506, and the output end of the servo motor 2 507 penetrates the mounting shell 506 and is connected to the threaded rod 3 508, and the threaded rod 3 508 is inserted into the output end of the servo motor 2 507. A tool holder 509 is sleeved on the outer circumference of the rod three 508, and limit rods 2 5010 cooperating with the mounting shell 506 are inserted on both sides of the tool holder 509. Two servo motors 3 5011 are penetrated on one side of the top of the tool holder 509, and the output ends of the servo motors 3 5011 are connected to tools 5012. An ear plate 5013 cooperating with the suspension component 6 is arranged on the top of one side of the concave frame 501, so that under the action of the adjustment component 5, the workpiece can be automatically adjusted horizontally and vertically, so that the position of the slider 2 504 and the tool holder 509 can be accurately controlled, thereby improving the working efficiency of the lifting and lowering operation mechanism of the vertical lathe.

[0031] The specific working principle of the adjustment component 5 is as follows: when the tool 5012 needs to be adjusted horizontally, the servo motor 1 502 is started to rotate forward through the control panel 8, and the servo motor 1 502 rotates forward to drive the threaded rod 2 503 to rotate forward, and then the threaded rod 2 503 rotates forward under the action of the limit rod 1 505, so that the slider 2 504 moves to the left, so that the slider 2 504 moves to the left and drives the mounting shell 506 to move to the left, and then drives the tool 5012 to move to the left. Conversely, when the servo motor 502 is turned on, the servo motor 1 502 rotates forward to drive the threaded rod 2 503 to rotate forward, and then the threaded rod 2 503 ... When 1 502 is reversed, it drives the tool 5012 to move to the right. When the tool 5012 needs to move vertically, the servo motor 2 507 is started to rotate forward through the control panel 8. The servo motor 2 507 rotates forward and drives the threaded rod 3 508 to rotate forward. Then, the threaded rod 3 508 rotates forward under the action of the limit rod 2 5010, so that the tool holder 509 moves downward, thereby driving the tool 5012 to move downward. Conversely, when the servo motor 2 507 is reversed, it drives the tool 5012 to move upward.

[0032] In one embodiment, for the above-mentioned suspension component 6, the suspension component 6 includes a fixed plate 601 arranged between the tops of the two column frames 2, a mounting frame 602 is arranged on the side wall of one end of the bottom of the fixed plate 601, a winding wheel 603 is arranged at the bottom of the mounting frame 602, and a suspension rope 604 is wound around the winding wheel 603, and the end of the suspension rope 604 is connected to a hook 605 matched with the ear plate 5013, and a servo motor 606 matched with it is arranged on one side of the winding wheel 603, a fixed shaft 607 is arranged on the top of the mounting frame 602, and a moving part 608 matched with it is sleeved in the middle of the fixed shaft 607, and symmetrical and staggered track grooves 609 are opened on the circumferential outer wall of the fixed shaft 607, and the moving part 6 A guide block 6010 is arranged on the inner wall of 08 and cooperates with the track groove 609. A wire groove 6011 is opened on the outer side of the movable part 608 and cooperates with the suspension rope 604. A pulley 6012 is arranged on the side wall at one end of the bottom of the fixed plate 601 and cooperates with the winding wheel 603. Under the action of the suspension component 6, the suspension rope 604 can be quickly and conveniently retracted and released, thereby reducing the load force on the slider 4 and the threaded rod 2 503. In addition, during the rope retraction process, the disorder caused by winding on the winding wheel 603 can be avoided, thereby avoiding the suspension rope 604 from getting knotted and affecting the subsequent suspension work, thereby improving the utilization rate and safety of the subsequent suspension rope 604, and having a wider applicability.

[0033] The specific working principle of the suspension component 6 is as follows: the output shaft of the servo motor 4 606 is started to rotate through the control panel 8, and the rotation of the output shaft of the servo motor 4 606 drives the winding wheel 603 to rotate. Since one end of the suspension rope 604 passes through the pulley 6012 and is wound around the winding wheel 603, the suspension rope 604 will drive the moving part 608 to rotate on the fixed shaft 607 during the winding process. The moving part 608 moves back and forth along the track groove 609 on the fixed shaft 607 under the action of the guide block 6010, so that the suspension rope 604 can be driven to move back and forth during the winding process of the suspension rope 604, so that the suspension rope 604 can be regularly and neatly wound on the winding wheel 603, thereby avoiding the suspension rope 604 from getting tangled, thereby improving the subsequent utilization rate of the suspension rope 604.

[0034] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0035] In actual application, first, the workpiece to be processed is placed on the three-jaw chuck body 7 for fixation, and then the drive motor 9 is started to rotate through the control panel 8, so that the drive motor 9 rotates to drive the threaded rod 3 to rotate, so that the threaded rod 3 drives the slider 4 to move up and down, and the slider 4 drives the adjustment component 5 to move up and down. During the movement of the adjustment component 5, the suspension component 6 is started through the control panel 8 to apply an auxiliary force to the adjustment component 5 when it moves. When the adjustment component 5 is above the workpiece, the adjustment component 5 is started to perform horizontal and vertical processing on the workpiece. When the processing is completed, the drive motor 9 and the suspension component 6 are started at the same time to drive the adjustment component 5 to move upward, and then the workpiece can be removed.
