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 the 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] It is precisely because the lathe needs to have multi-directional degrees of freedom that the machining datum needs to be repeatedly positioned during the machining process. In the field of fine machining, the fewer machining datums the better. The reason is that reducing the number of datums can reduce the error caused by the misalignment of the datums and ensure the accuracy of the machining. In multi-step machining, using the same datum surface can reduce the error caused by the datum transformation, thereby improving the machining accuracy.

[0005] Currently, the common machining centers in the industry are divided into two categories. One is that the worktable moves during the machining process to adapt to the product shape; the other is that the tool 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 adapt to the product's external dimensions. However, since the front and rear movements are unrelated, the workbench's datums before and after adjustment cannot form effective constraints, there are too many processing datums, and the accuracy is not satisfactory.

[0017] A precision turning method with a multi-dimensional leveling function of a workbench comprises the following steps: Step 1: When leveling the workbench, control the movement of the bidirectional transmission mechanism through the drive switching mechanism; Step 2: Under the action of the bidirectional transmission mechanism, the multi-directional control mechanism is moved to drive the multi-dimensional support mechanism to move. Under the action of the multi-dimensional support mechanism, the workbench is controlled to perform a vertical and horizontal deflection action; Step 3: After the deflection reaches 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 to deflect in the vertical longitudinal direction through the multi-directional control mechanism and the multi-dimensional support mechanism until the workbench deflects to the specified angle.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0025] See also Figure 1 to Figure 10 In an embodiment of the present invention, a lathe worktable multi-dimensional leveling turning precision compound machining center includes: a turning compound machining center 1, and a supporting plate 2 fixedly mounted on the turning compound machining center 1, wherein the supporting plate 2 is fixed with a first fixed plate 201 and a second fixed plate 202 symmetrically arranged, and the supporting plate 2 is also fixed with a support plate 3 and a baffle 11; further comprising: a first ball connector 4 fixedly mounted on the support plate 3, and a worktable 5 is ball-connected to the first ball connector 4; a multi-dimensional support mechanism, which is arranged on the supporting plate 2 and connected to the worktable 5, and the first fixed plate 201 and the second fixed plate 202 are provided with a multi-directional control mechanism connected to the multi-dimensional support mechanism, and the multi-directional control mechanism can adjust the deflection angle of the worktable 5 through the multi-dimensional support mechanism; a bidirectional transmission mechanism, which is arranged on the baffle 11 and connected to the multi-directional control mechanism, and the support plate 3 is provided with a drive switching mechanism connected to the bidirectional transmission mechanism, and the drive switching mechanism can drive the multi-dimensional support mechanism to move through the bidirectional transmission mechanism.

[0026] Specifically, a sensor is provided on the support plate 2, which can monitor the yaw angle of the workbench in real time according to the processing requirements, and feed back 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, the workbench 5 needs to be adjusted in a single direction each time. Therefore, under the action of the drive switching mechanism, the bidirectional transmission mechanism can be controlled to transmit in one direction. Under the action of the bidirectional transmission mechanism, the multi-dimensional support mechanism is driven to move through the multi-directional control mechanism to control the workbench 5 to perform a yaw action 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 transmit in another direction, so as to control the workbench 5 to perform a yaw action along the vertical and longitudinal directions through the multi-directional control mechanism and the multi-dimensional support mechanism until the leveling of the workbench 5 is completed. By adjusting the workbench 5 in the vertical, horizontal and longitudinal directions in a single manner, the stability and accuracy of the leveling can be ensured, and the workbench 5 can be multi-dimensionally adjusted to the desired position. Among them, the sensor is an application of the prior art and is not elaborated in this application.

[0027] See also Figure 1-Figure 6 , Fig. 9 , Fig.10 The multi-dimensional support mechanism includes a fixed sleeve 20 fixedly installed on the support plate 2 and symmetrically arranged, a groove 2001 is opened on the circumferential outer wall of the fixed sleeve 20, a support rod 21 is slidably installed in the fixed sleeve 20, a limiting column 2101 slidingly connected to the groove 2001 is fixed on the support rod 21, and a sliding component connected to the workbench 5 is arranged on the limiting column 2101, wherein the sliding component includes a first slide groove 501 and a second slide groove 502 opened on the workbench 5 and symmetrically arranged, a sliding block 23 is slidably installed in the first slide groove 501 and the second slide groove 502, and a second ball connector 22 fixedly connected to the support rod 21 is ball-connected on the sliding block 23.

[0028] In detail, the workbench 5 is equipped with a clamping workpiece for clamping the parts to be processed. In order to ensure the accuracy during turning, the workbench 5 needs to be leveled. Four fixed sleeves 20 are provided, and the first ball connector 4 is used as the center point. Two of the fixed sleeves 20 are located at laterally symmetrical positions of the central axis of the workbench 5, and the other two fixed sleeves 20 are located at longitudinally symmetrical positions of the central axis of the workbench 5. Taking the workbench 5 as the horizontal reference plane, the centers of the first ball connector 4 and the second ball connector 22 are located in the same horizontal plane. When it is necessary to adjust the vertical and horizontal deflection angles of the workbench 5, under the action of the drive switching mechanism, the multi-directional control mechanism is driven to move through the bidirectional transmission mechanism, so as to control the support rod 21 located in one of the longitudinally symmetrically arranged fixed sleeves 20 to move toward the support plate 2 through the limit column 2101. The second ball connector 22 drives the sliding block 23 to move, and the other support rod 21 located in the symmetrical position moves in the direction away from the supporting plate 2, so that the workbench 5 swings around the first ball connector 4. When the workbench 5 completes the vertical and horizontal swinging, the driving switching mechanism can drive the multi-directional regulating mechanism to move through the two-way transmission mechanism, so as to control the support rod 21 located in one of the laterally symmetrically arranged fixed sleeves 20 to move toward the supporting plate 2 through the limit column 2101, so as to adjust the vertical and horizontal angle of the workbench 5. Through the single adjustment in the horizontal and longitudinal directions, the accuracy and stability of the leveling of the workbench 5 are ensured, and in the adjustment process, under the action of the first ball connector 4, the reference center of the workbench 5 can be ensured to remain unchanged at all times, thereby ensuring the accuracy of the adjustment of the workbench 5.

[0029] See also Figure 1-Figure 6 , Fig. 9 , Fig.10 The multi-directional control mechanism includes a first screw rod 14 and a second screw rod 28 rotatably mounted on the first fixing plate 201 and the second fixing plate 202, respectively. The first screw rod 14 is threadedly connected with a first threaded sleeve 16 symmetrically arranged, and the second screw rod 28 is threadedly connected with a second threaded sleeve 30 symmetrically arranged. The first fixing plate 201 and the second fixing plate 202 are provided with a guide assembly connected to the limit column 2101, wherein the guide assembly includes a first screw rod 14 and a second screw rod 28 respectively fixedly mounted on the first fixing plate 201 and the second fixing plate 202. The first guide column 18 and the second guide column 31 on the fixed plate 202, the first guide column 18 is slidably mounted with a first guide sleeve 19 symmetrically arranged, and the second guide column 31 is slidably mounted with a second guide sleeve 32 symmetrically arranged; it also includes a movable plate 17 fixed to the side walls of the first guide sleeve 19 and the second guide sleeve 32, the movable plate 17 is respectively fixedly connected to the first threaded sleeve 16 and the second threaded sleeve 30, and the movable plate 17 is provided with an inclined groove 1701 slidably connected to the limiting column 2101.

[0030] It should be noted that two threaded parts are formed on the first screw rod 14 and the second screw rod 28 respectively. When the vertical and horizontal deflection angles of the workbench 5 need to be adjusted, the first screw rod 14 is controlled to rotate forward or reverse according to the required deflection direction under the action of the bidirectional transmission mechanism. At this time, the second screw rod 28 is in a stationary state. Under the action of the first screw rod 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 column 18 through the movable plate 17. Due to the first guide sleeve 19 and the first guide column 18 It has a guiding function, which can ensure that the two first threaded sleeves 16 move along the length direction of the first screw rod 14 and will not rotate with the first screw rod 14. The movable plate 17 will also drive the inclined groove 1701 to move. Under the action of the two inclined grooves 1701 and the two limit columns 2101, one of the support rods 21 is controlled to move toward the fixed sleeve 20, and the other support rod 21 moves in the direction away from the fixed sleeve 20, and the movement speed is equal. After the vertical and horizontal swing angles of the workbench 5 are adjusted, similarly, the vertical and longitudinal swing angles of the workbench 5 can be adjusted through the two-way transmission mechanism.

[0031] Preferably, through the action of the inclined groove 1701 and the limit column 2101, the two support rods 21 can be controlled to perform reverse equal-speed lifting and lowering movements, so as to synchronously support the deflection of the workbench 5 in two directions, thereby ensuring the stability of the workbench 5 during adjustment, and when the transmission is performed through the first screw rod 14 and the second screw rod 28, it also has the effect of high adjustment accuracy, thereby ensuring the accuracy of the deflection angle of the workbench 5.

[0032] See also Figure 2 , Figure 4-Figure 8 The bidirectional transmission mechanism includes a first rotating sleeve 12 and a second rotating sleeve 24 which are rotatably mounted on the two baffles 11 respectively, a first limiting tooth 1201 is fixed on the first rotating sleeve 12, and a second limiting tooth 2401 is fixed on the second rotating sleeve 24, and a driven component connected to the first rotating sleeve 12 and the second rotating sleeve 24 is provided on the support plate 3, wherein the driven component includes a first gear 13 fixedly mounted on the first rotating sleeve 12, and a second gear 15 meshing with the first gear 13 is fixed on the first screw rod 14; and also includes a rotating rod 26 rotatably mounted on the support plate 3, a belt 25 connected to the second rotating sleeve 24 is sleeved on the rotating rod 26, a first bevel gear 27 is fixed on 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 screw rod 28.

[0033] Furthermore, when it is necessary to adjust the vertical and horizontal deflection angles of the workbench 5, under the action of the drive switching mechanism, the drive switching mechanism and the first limit tooth 1201 are in a matching state. 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 first gear 13 to rotate. Since the first gear 13 is meshed with the second gear 15, the first screw rod 14 will rotate, thereby adjusting the vertical and horizontal deflection angles of the workbench 5. Since the drive switching mechanism and the second limit tooth 2401 are in a separated state at this time, the second screw rod 28 remains stationary. After the vertical and horizontal swing angles of the table 5 are adjusted, the drive switching mechanism will separate from the first limit tooth 1201 and move to a position cooperating with the second limit tooth 2401, thereby driving the second rotating sleeve 24 to rotate. The second rotating sleeve 24 will drive the rotating rod 26 to rotate through the belt 25, thereby driving the first bevel gear 27 to rotate. Since the first bevel gear 27 is meshed with the second bevel gear 29, the second screw rod 28 rotates, thereby adjusting the vertical and longitudinal swing angles of the workbench 5. When the adjustment is completed, the drive switching mechanism will move to a position separated from both the first limit tooth 1201 and the second limit tooth 2401.

[0034] Preferably, by adjusting the matching state between the drive switching mechanism and the first limit tooth 1201 and the second limit tooth 2401, it is possible to realize the transmission of the first screw rod 14 or the second screw rod 28 separately, and after the swing angle adjustment of the workbench 5 is completed, the drive switching mechanism is controlled to separate from the first limit tooth 1201 and the second limit tooth 2401, so as to prevent the problem of deviation of the workbench 5 due to misoperation.

[0035] See also Figure 2 , Figure 4-Figure 8 The drive switching mechanism includes a motor 6 fixedly mounted on the supporting plate 2, a transmission rod 7 connected to the output shaft of the motor 6 is rotatably mounted on the baffle 11, a movable sleeve 8 is slidably mounted on the transmission rod 7, and a first fixed tooth 801 and a second fixed tooth 802 are respectively fixed at both ends of the movable sleeve 8, the first fixed tooth 801 cooperates with the first limit tooth 1201, and the second fixed tooth 802 cooperates with the second limit tooth 2401, and a pushing assembly connected to the movable sleeve 8 is provided on the support plate 3, wherein the pushing assembly includes a cylinder 9 fixedly mounted on the support plate 3, and a connecting plate 10 is fixed at the telescopic end of the cylinder 9, and the connecting plate 10 is rotatably connected to the movable sleeve 8.

[0036] To go further, in the initial state, the first fixed tooth 801 and the second fixed tooth 802 are in a separated state from the first limit tooth 1201 and the second limit tooth 2401. At this time, when the motor 6 is working, the first screw rod 14 and the second screw rod 28 are in a stationary state. When the workbench 5 needs to be adjusted vertically and horizontally, the cylinder 9 works and controls the movable sleeve 8 to move toward 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 working, and the second fixed tooth 802 is in a separated state from the second limit tooth 2401. At this time, the motor 6 works and drives the transmission rod 7 to rotate, thereby driving the movable sleeve 8 to rotate synchronously. The movable sleeve 8 will The latch tooth 1201 drives the first rotating sleeve 12 to rotate, thereby controlling the workbench 5 to perform a yaw motion along the vertical and horizontal directions. When the workbench 5 completes the vertical and horizontal yaw motion, the cylinder 9 can control the movable sleeve 8 to move toward the second rotating sleeve 24, so that the first fixed latch tooth 801 is separated from the first limit latch tooth 1201, and the second fixed latch tooth 802 is moved to a position engaged with the second limit latch tooth 2401. The cylinder 9 stops moving, and the motor 6 works 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 latch tooth 802 and the second limit latch tooth 2401, so as to control the workbench 5 to perform a yaw motion along the vertical and longitudinal directions. When the yaw motion is completed, the cylinder 9 controls the movable sleeve 8 to reset, so that the first fixed latch tooth 801 and the second fixed latch tooth 802 are separated from the first limit latch tooth 1201 and the second limit latch tooth 2401 again.

[0037] Preferably, the transmission state of the first screw rod 14 and the second screw rod 28 can be switched by the cylinder 9 to achieve a single adjustment of the vertical, lateral or longitudinal swing angle of the workbench 5. At the same time, after the adjustment is completed, it can be ensured that the first screw rod 14 and the second screw rod 28 cannot rotate to prevent the motor 6 from working due to misoperation, resulting in the problem of the swing angle of the workbench 5 being offset.

[0038] A method for adjusting a workbench with a multi-dimensional leveling function, comprising the following steps: Step 1: When the workbench 5 is leveled, the bidirectional transmission mechanism is controlled to move by the driving switching mechanism; Step 2: Under the action of the bidirectional 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, the workbench 5 is controlled to perform a vertical and horizontal deflection action; Step three: After the deflection reaches the specified angle, the driving switching mechanism moves again and changes the transmission state of the bidirectional transmission mechanism, so as to control the workbench 5 to deflect in the vertical longitudinal direction through the multi-directional control mechanism and the multi-dimensional support mechanism until the workbench 5 deflects to the specified angle.
