Description

Technical Field

[0001] The invention relates to the technical field of lathe leveling, in particular to a multi-dimensional leveling turning precision composite machining center for a lathe worktable and a method thereof. Background Art

[0002] The precision turning machining center is a high-precision metal processing equipment, mainly used for precision machining of various rotating parts.

[0003] During the precision machining process of a turning machining center, for some products with partially non-coaxial structures (such as crankshafts) or coaxial but tapered products (such as tapered mandrels), the machine tool needs to have multiple degrees of freedom, including X-axis deflection freedom, Y-axis deflection freedom, and Z-axis lifting freedom.

[0004] Because lathes require multiple degrees of freedom, repeated positioning of machining datums is necessary during machining. In finishing, the principle of fewer datums is generally followed. This is because reducing the number of datums reduces errors caused by datum misalignment, ensuring machining accuracy. Using a single datum plane in multi-step machining reduces errors caused by datum shifting, thereby improving machining accuracy.

[0005] Currently, common machining centers in the industry are divided into two categories. One type has a worktable that moves during the machining process to adapt to the product shape; the other type has a tool that moves to adapt to the product shape. However, since the tool bears the cutting force, if the tool has both movable and cutting performance, its precision errors will be superimposed, thereby amplifying the machining error.

[0006] In the prior art, the workbench is used to move to meet the product's external dimensions. However, since the front and rear movements are unrelated, the workbench's benchmarks before and after adjustment cannot form effective constraints, there are too many processing benchmarks, and the accuracy is unsatisfactory. Summary of the Invention

[0013] As a further solution of the present invention: The bidirectional transmission mechanism includes a first rotating sleeve and a second rotating sleeve respectively rotatably installed on the two baffles. A first limiting tooth is fixed on the first rotating sleeve, and a second limiting tooth is fixed on the second rotating sleeve. A driven assembly connected to the first rotating sleeve and the second rotating sleeve is arranged on the support plate.

[0014] As a further solution of the present invention: The driven assembly includes a first gear fixedly installed on the first rotating sleeve, and a second gear meshing with the first gear is fixed on the first lead screw; It also includes a rotating rod rotatably installed on the support plate. A belt connected to the second rotating sleeve is sleeved on the rotating rod. A first bevel gear is fixed at the end of the rotating rod, and a second bevel gear meshing with the first bevel gear is fixed on the second lead screw.

[0016] As a further solution of the present invention: The pushing assembly includes a cylinder fixedly installed on the support plate. A connecting plate is fixed at the telescopic end of the cylinder, and the connecting plate is rotatably connected to the movable sleeve.

[0017] A precision turning method with a multi-dimensional leveling function for a workbench includes the following steps:

[0018] Step 1: When leveling the workbench, control the movement of the bidirectional transmission mechanism through the drive switching mechanism;

[0019] Step 2: Under the action of the bidirectional transmission mechanism, the multi-directional regulation mechanism moves to drive the multi-dimensional support mechanism to move. Under the action of the multi-dimensional support mechanism, control the workbench to make a yaw motion in the vertical and horizontal directions;

[0020] Step 3: When yawing to a specified angle, the drive switching mechanism moves again and changes the transmission state of the bidirectional transmission mechanism to control the workbench to make a yaw motion in the vertical and longitudinal directions through the multi-directional regulation mechanism and the multi-dimensional support mechanism until the workbench yaws to the specified angle.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This application can adjust the motion state of the bidirectional transmission mechanism through the drive switching mechanism to achieve the adjustment of the vertical, horizontal, and longitudinal yaw angles of the workbench at the same reference point, ensuring the accuracy and stability of the workbench leveling. Specifically, when adjusting the vertical and horizontal yaw angles of the workbench, the drive switching mechanism works to adjust the transmission direction of the bidirectional transmission mechanism, so as to adjust the yaw angles of the workbench in the vertical and horizontal directions through the multi-directional control mechanism and the multi-dimensional support mechanism. After the adjustment is completed, the drive switching mechanism can adjust the transmission direction of the bidirectional transmission mechanism again to adjust the yaw angles of the workbench in the vertical and longitudinal directions through the multi-directional control mechanism and the multi-dimensional support mechanism. By adjusting the horizontal and longitudinal directions separately, the accuracy and stability of the workbench leveling are ensured. During the adjustment process, under the action of the first ball joint, the central reference position of the workbench always remains unchanged, thereby ensuring that the accuracy of the workbench remains at a high level after multiple repeated adjustments.

[0022] Under the action of the inclined groove and the limit post, it is possible to control the two support rods to move up and down in opposite directions at the same speed, so as to synchronously support and yaw the workbench in two directions, ensuring the stability of the workbench during adjustment. Moreover, when driving through the first screw rod and the second screw rod, there is also the effect of high adjustment accuracy, which can ensure the accuracy of the yaw angle adjustment of the workbench.

[0023] After the leveling is completed, the air cylinder controls the movable sleeve to reset, so that the first fixed tooth and the second fixed tooth are separated from the first limit tooth and the second limit tooth again, ensuring that both the first screw rod and the second screw rod cannot rotate, so as to prevent the motor from working due to misoperation, resulting in the problem that the yaw angle of the workbench deviates.

Detailed implementation manners

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] In addition, the elements in the present invention are referred to as "fixed to" or "disposed on" another element, which can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0037] Please refer to Figures 1 to 10 , in the embodiment of the present invention, a multi-dimensional leveling type turning precision composite machining center for a lathe workbench includes: a turning composite machining center 1, and a supporting plate 2 fixedly installed on the turning composite machining center 1. A first fixing plate 201 and a second fixing plate 202 are symmetrically arranged and fixed on the supporting plate 2. A supporting plate 3 and a baffle 11 are also fixed on the supporting plate 2. It further includes: a first ball joint 4 fixedly installed on the supporting plate 3, and a workbench 5 is ball-jointed on the first ball joint 4; a multi-dimensional support mechanism is arranged on the supporting plate 2 and connected to the workbench 5. A multi-directional adjustment mechanism connected to the multi-dimensional support mechanism is arranged on the first fixing plate 201 and the second fixing plate 202. The multi-directional adjustment mechanism can adjust the yaw angle of the workbench 5 through the multi-dimensional support mechanism; a two-way transmission mechanism is arranged on the baffle 11 and connected to the multi-directional adjustment mechanism. A drive switching mechanism connected to the two-way transmission mechanism is arranged on the supporting plate 3. The drive switching mechanism can drive the multi-dimensional support mechanism to move through the two-way transmission mechanism.

[0038] Specifically, a sensor is provided on the supporting plate 2, which can monitor the yaw angle of the workbench in real time according to the processing requirements and feedback it to the drive switching mechanism to adjust the workbench in real time. When leveling the workbench 5, in order to ensure the stability of part processing, it is necessary to adjust the workbench 5 in a single direction each time. Therefore, under the action of the drive switching mechanism, the bidirectional transmission mechanism can be controlled to drive in one direction. Under the action of the bidirectional transmission mechanism, the multi-directional control mechanism drives the multi-dimensional support mechanism to move, so as to control the workbench 5 to make a yaw motion along the vertical and horizontal directions. When the adjustment in this direction is completed, under the action of the drive switching mechanism, the bidirectional transmission mechanism is controlled to drive in the other direction, so as to control the workbench 5 to make a yaw motion along the vertical and longitudinal directions through the multi-directional control mechanism and the multi-dimensional support mechanism until the workbench 5 is leveled. By adjusting the workbench 5 in a single direction along the vertical and horizontal directions, the stability and accuracy during leveling can be ensured, and the workbench 5 can be multi-dimensionally adjusted to the required position. Among them, the sensor is an application of the prior art, and this application will not be elaborated.

[0039] Please refer to Figures 1 - 6 、 Figure 9 、 Figure 10 As shown in FIGS.

[0040] Specifically, a clamping workpiece for clamping a part to be machined is installed on the workbench 5. To ensure the accuracy during turning machining, the workbench 5 needs to be leveled. There are four fixed sleeves 20, with the first ball joint 4 as the center point. Two of the fixed sleeves 20 are located at the transverse symmetry positions of the central axis of the workbench 5, and the other two fixed sleeves 20 are located at the longitudinal symmetry positions of the central axis of the workbench 5. Taking the workbench 5 as the horizontal reference plane, the centers of the first ball joint 4 and the second ball joint 22 are located on the same horizontal plane. When it is necessary to adjust the yaw angle of the workbench 5 in the vertical and horizontal directions, under the action of the drive switching mechanism, the multi-directional control mechanism is driven by the bidirectional transmission mechanism, so that the support rod 21 located in one of the longitudinally symmetrically arranged fixed sleeves 20 is controlled by the limit post 2101 to move towards the supporting plate 2, thereby driving the sliding block 23 to move through the second ball joint 22, while the other support rod 21 located at the symmetric position will move away from the supporting plate 2, causing the workbench 5 to yaw around the first ball joint 4. After the workbench 5 completes yawing in the vertical and horizontal directions, the drive switching mechanism can drive the multi-directional control mechanism through the bidirectional transmission mechanism, so that the support rod 21 located in one of the transversely symmetrically arranged fixed sleeves 20 is controlled by the limit post 2101 to move towards the supporting plate 2, thereby adjusting the angle of the workbench 5 in the vertical and horizontal directions. Through single adjustment in the transverse and longitudinal directions, the accuracy and stability of leveling the workbench 5 are ensured. And during the adjustment process, under the action of the first ball joint 4, it can be ensured that the reference center of the workbench 5 always remains unchanged, thus guaranteeing the accuracy of adjusting the workbench 5.

[0041] Please refer to Figures 1 - 6 、 Figure 9 、 Figure 10 The multi-directional control mechanism includes a first lead screw 14 and a second lead screw 28 that are respectively rotatably installed on the first fixing plate 201 and the second fixing plate 202. Symmetrically arranged first threaded sleeves 16 are threadedly connected to the first lead screw 14, and symmetrically arranged second threaded sleeves 30 are threadedly connected to the second lead screw 28. A guiding component connected to the limit post 2101 is arranged on the first fixing plate 201 and the second fixing plate 202. Among them, the guiding component includes a first guiding post 18 and a second guiding post 31 that are respectively fixedly installed on the first fixing plate 201 and the second fixing plate 202. Symmetrically arranged first guiding sleeves 19 are slidably installed on the first guiding post 18, and symmetrically arranged second guiding sleeves 32 are slidably installed on the second guiding post 31; An activity plate 17 fixed to the side walls of the first guiding sleeve 19 and the second guiding sleeve 32 is also included. The activity plate 17 is respectively fixedly connected to the first threaded sleeve 16 and the second threaded sleeve 30, and an inclined slot 1701 slidably connected to the limit post 2101 is formed on the activity plate 17.

[0042] It should be noted that two threaded portions are respectively formed on the first lead screw 14 and the second lead screw 28. When it is necessary to adjust the yaw angle of the workbench 5 in the vertical and horizontal directions, under the action of the bidirectional transmission mechanism, according to the required yaw direction, the first lead screw 14 is controlled to rotate forward or backward. At this time, the second lead screw 28 is in a static state. Under the action of the first lead screw 14, the two first threaded sleeves 16 are driven to move in the same direction. The first threaded sleeve 16 also controls the first guide sleeve 19 to move along the length direction of the first guide post 18 through the movable plate 17. Since the first guide sleeve 19 and the first guide post 18 have a guiding effect, it can ensure that the two first threaded sleeves 16 move along the length direction of the first lead screw 14 and will not rotate with the first lead screw 14. The movable plate 17 also drives the inclined groove 1701 to move. Under the action of the two inclined grooves 1701 and the two limit posts 2101, one of the support rods 21 is controlled to move towards the inside of the fixed sleeve 20, and the other support rod 21 moves away from the fixed sleeve 20, and the movement speeds are equal. When the yaw angle of the workbench 5 in the vertical and horizontal directions is adjusted, similarly, the yaw angle of the workbench 5 in the vertical and longitudinal directions can be adjusted through the bidirectional transmission mechanism.

[0043] Preferably, under the action of the inclined groove 1701 and the limit post 2101, it is possible to control the two support rods 21 to perform reverse and equal-speed lifting and lowering movements, so as to realize synchronous support and yaw of the workbench 5 in two directions, ensure the stability of the workbench 5 during adjustment, and when driving through the first lead screw 14 and the second lead screw 28, there is also an effect of high adjustment accuracy, which can ensure the accuracy of the yaw angle adjustment of the workbench 5.

[0044] Please refer to Figure 2 、 Figures 4 - 8 As shown in, the bidirectional transmission mechanism includes a first rotating sleeve 12 and a second rotating sleeve 24 respectively rotatably installed on the two baffles 11. A first limit tooth 1201 is fixed on the first rotating sleeve 12, and a second limit tooth 2401 is fixed on the second rotating sleeve 24. A driven assembly connected to the first rotating sleeve 12 and the second rotating sleeve 24 is arranged on the support plate 3. Among them, the driven assembly includes a first gear 13 fixedly installed on the first rotating sleeve 12, and a second gear 15 meshing with the first gear 13 is fixed on the first lead screw 14; it also includes a rotating rod 26 rotatably installed on the support plate 3. A belt 25 connected to the second rotating sleeve 24 is sleeved on the rotating rod 26, and a first bevel gear 27 is fixed at the end of the rotating rod 26, and a second bevel gear 29 meshing with the first bevel gear 27 is fixed on the second lead screw 28.

[0045] Furthermore, when it is necessary to adjust the yaw angle of the workbench 5 in the vertical and horizontal directions, under the action of the drive switching mechanism, the drive switching mechanism is in a cooperative state with the first limit tooth 1201. At this time, the drive switching mechanism can control the rotation of the first rotating sleeve 12 through the first limit tooth 1201, thereby driving the rotation of the first gear 13. Since the first gear 13 meshes with the second gear 15, the first lead screw 14 will rotate, thereby adjusting the yaw angle of the workbench 5 in the vertical and horizontal directions. Since the drive switching mechanism is in a separated state from the second limit tooth 2401 at this time, the second lead screw 28 remains stationary. After the yaw angle of the workbench 5 in the vertical and horizontal directions is adjusted, the drive switching mechanism will be separated from the first limit tooth 1201 and move to the position where it cooperates with the second limit tooth 2401, thereby driving the rotation of the second rotating sleeve 24. The second rotating sleeve 24 will drive the rotation of the rotating rod 26 through the belt 25, thereby driving the rotation of the first bevel gear 27. Since the first bevel gear 27 meshes with the second bevel gear 29, the second lead screw 28 rotates, thereby adjusting the yaw angle of the workbench 5 in the vertical and longitudinal directions. After the adjustment is completed, the drive switching mechanism will move to the position where it is separated from both the first limit tooth 1201 and the second limit tooth 2401.

[0046] Preferably, by adjusting the cooperative state of the drive switching mechanism with the first limit tooth 1201 and the second limit tooth 2401, the transmission of the first lead screw 14 or the second lead screw 28 can be realized separately, and after the yaw angle adjustment of the workbench 5 is completed, the drive switching mechanism is controlled to be separated from the first limit tooth 1201 and the second limit tooth 2401, thereby preventing the problem that the workbench 5 is displaced due to misoperation.

[0047] Please refer to Figure 2 、 Figures 4 - 8 The drive switching mechanism includes a motor 6 fixedly installed on the support plate 2. A transmission rod 7 connected to the output shaft of the motor 6 is rotatably installed on the baffle 11. A movable sleeve 8 is slidably installed on the transmission rod 7. First fixed teeth 801 and second fixed teeth 802 are respectively fixed at both ends of the movable sleeve 8. The first fixed teeth 801 cooperate with the first limit teeth 1201, and the second fixed teeth 802 cooperate with the second limit teeth 2401. A pushing component connected to the movable sleeve 8 is arranged on the support plate 3. Among them, the pushing component includes a cylinder 9 fixedly installed on the support plate 3. A connecting plate 10 is fixed at the telescopic end of the cylinder 9. The connecting plate 10 is rotatably connected to the movable sleeve 8.

[0048] Furthermore, in the initial state, the first fixed tooth 801 and the second fixed tooth 802 are both in a separated state from the first limit tooth 1201 and the second limit tooth 2401. At this time, when the motor 6 operates, the first lead screw 14 and the second lead screw 28 are both in a stationary state. When it is necessary to adjust the workbench 5 vertically and horizontally, at this time, the cylinder 9 operates and controls the movable sleeve 8 to move towards the first rotating sleeve 12 through the connecting plate 10. The movable sleeve 8 will drive the first fixed tooth 801 to move. When the first fixed tooth 801 moves to the engaging position with the first limit tooth 1201, the cylinder 9 stops operating. The second fixed tooth 802 is in a separated state from the second limit tooth 2401. At this time, the motor 6 operates and drives the transmission rod 7 to rotate, thereby driving the movable sleeve 8 to rotate synchronously. The movable sleeve 8 will drive the first rotating sleeve 12 to rotate through the first fixed tooth 801 and the first limit tooth 1201, thereby controlling the workbench 5 to perform a yawing motion along the vertical and horizontal directions. After the workbench 5 completes the yawing in the vertical and horizontal directions, the cylinder 9 can control the movable sleeve 8 to move towards the second rotating sleeve 24, so that the first fixed tooth 801 is separated from the first limit tooth 1201, and the second fixed tooth 802 moves to the engaging position with the second limit tooth 2401. The cylinder 9 stops moving, and the motor 6 operates again to drive the movable sleeve 8 to rotate again. The movable sleeve 8 will control the second rotating sleeve 24 to rotate through the second fixed tooth 802 and the second limit tooth 2401 to control the workbench 5 to perform a yawing motion along the vertical and longitudinal directions. After the yawing is completed, the cylinder 9 controls the movable sleeve 8 to reset, so that the first fixed tooth 801 and the second fixed tooth 802 are separated from the first limit tooth 1201 and the second limit tooth 2401 again.

[0049] Preferably, the transmission state of the first lead screw 14 and the second lead screw 28 can be switched through the cylinder 9 to achieve a single adjustment of the yaw angle of the workbench 5 vertically and horizontally or longitudinally. At the same time, after the adjustment is completed, it can also be ensured that the first lead screw 14 and the second lead screw 28 cannot rotate to prevent the problem that the motor 6 operates due to misoperation, resulting in an offset of the yaw angle of the workbench 5.

[0050] An adjustment method with a multi-dimensional leveling function for a workbench includes the following steps:

[0051] Step 1: When leveling the workbench 5, control the two-way transmission mechanism to move through the drive switching mechanism;

[0052] Step 2: Under the action of the two-way transmission mechanism, the multi-directional control mechanism moves to drive the multi-dimensional support mechanism to move. Under the action of the multi-dimensional support mechanism, control the workbench 5 to perform a yawing action in the vertical and horizontal directions;

[0053] Step 3: After yawing to the specified angle, the drive switching mechanism moves again and changes the transmission state of the bidirectional transmission mechanism, so as to control the workbench 5 to perform a yawing motion in the vertical longitudinal direction through the multi-directional regulation mechanism and the multi-dimensional support mechanism until the workbench 5 yaws to the specified angle.
