Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically to a lathe tool path structure. Background Technology

[0002] CNC lathes and turning centers are high-precision, high-efficiency automated machine tools equipped with multi-station turrets or power turrets. These machines have a wide range of machining capabilities and can process complex workpieces such as straight cylinders, inclined cylinders, arcs, and various threads, grooves, and worm gears. They also have various compensation functions such as linear interpolation and circular interpolation, and have achieved good economic results in the mass production of complex parts.

[0003] A search revealed that patent CN202320495740.1 discloses a composite sliding CNC lathe that facilitates cleaning. While this device uses a telescopic plate and a fixed column to secure a large disc to a connecting block, causing the large disc to rotate and the small column to rotate along with its edge, and the large column to fix a rotating rod which then rotates under the influence of the small column, causing the air intake to swing left and right to clean the worktable and reduce unnecessary manual cleaning, this device lacks control over the cutter head angle. This inability to control the cutter head angle means that during machining, the tool can only cut at a fixed angle and cannot be flexibly adjusted according to machining requirements. This limits the lathe's application in complex machining tasks, especially in situations requiring variable angle cutting, preventing the achievement of desired machining results. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lathe tool path structure that solves the problems mentioned in the background art.

[0005] The solution of this utility model to the above-mentioned technical problems is as follows:

[0007] A third motor is mounted on the frame, and a lead screw is mounted on the output end of the third motor. Slide rails are mounted on both sides of the lead screw on the frame. An mounting plate is mounted on the frame via the lead screw and slide rails. The mounting plate is provided with a slider and a nut seat. The mounting plate is mounted on the frame by means of the slider and nut seat cooperating with the slide rails and the lead screw of the third motor for limiting its position. A second adjusting seat is slidably mounted on the mounting plate via a limiting plate. A first adjusting seat is slidably mounted on the second adjusting seat. A cutter head is fixed on the first adjusting seat.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, a first motor is mounted on the base plate, a lead screw is mounted on the output end of the first motor, slide rails are provided on both sides of the lead screw on the base plate, and a slider and nut seat are provided at the bottom end of the slide plate.

The slide is installed on the slide plate by means of the slider and the nut seat cooperating with the slide rails and the lead screw of the second motor for limiting.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] By installing a second motor and lead screw on the slide plate, two-stage transmission control of the slide table is achieved. This design allows the slide table to not only move on the slide plate, but also flexibly change its speed and direction by adjusting the speed and direction of the second motor. The cooperation between the lead screw and the nut seat ensures high-precision linear motion of the slide table on the slide plate.

[0015] Furthermore, the limiting plate is provided with a first sliding groove, the second adjusting seat is provided with a pin, the second adjusting seat is rotatably mounted on the limiting plate through the pin, and the second adjusting seat is provided with a fixing bolt, the second adjusting seat slides longitudinally between the limiting plate with the pin as the center through the fixing bolt and the first sliding groove.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] This design allows the second adjusting seat to slide longitudinally around the pin on the limiting plate, thus facilitating the adjustment of its angle and position. This flexibility enables the lathe to handle workpieces of different shapes and sizes, improving machining adaptability and flexibility. The cooperation between the pin and the limiting plate provides stable support for the second adjusting seat, ensuring its stability and reliability during adjustment. This stability helps reduce vibration and errors during machining, improving machining efficiency and quality.

[0020] This design allows the first adjusting seat to slide laterally on the second adjusting seat, and combined with the longitudinal sliding of the second adjusting seat on the limiting plate, it enables omnidirectional adjustment of the first adjusting seat in three-dimensional space. This multi-dimensional adjustment capability allows the lathe to handle more complex and precise machining requirements, improving machining flexibility and adaptability. Precise adjustment of the fixing bolts within the second slide groove allows for precise control of the angle and position of the first adjusting seat. This high-precision positioning capability is crucial for ensuring machining accuracy and workpiece quality, helping to reduce machining errors and improve machining efficiency.

[0033] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0034] Example 1

[0035] A lathe tool track structure includes a base plate 1, a slide plate 2 slidably mounted on the base plate 1, a first motor 14 mounted on the base plate 1, a lead screw 13 mounted on the output end of the first motor 14, slide rails 11 on both sides of the lead screw 13 on the base plate 1, and a slider 10 and a nut seat 12 at the bottom of the slide plate 2. The slide plate 2 is mounted on the base plate 1 through the cooperation of the slider 10 and the nut seat 12 with the slide rails 11 and the lead screw 13 of the first motor 14. The cooperation of the lead screw and the nut seat enables high-precision linear motion, which is crucial for machining requiring precise control. The slide rails provide stable guidance, ensuring that the slide plate does not deviate from the predetermined path during movement, further improving positioning accuracy. The combined structure of the slide rails and sliders can withstand large loads and has good vibration resistance, ensuring that the slide plate remains stable during machining. The lead screw drive has a self-locking function, which keeps the slide plate in place even in the event of a power outage, increasing the reliability of the system. A slide table 3 is slidably mounted on slide plate 2, and a second motor 15 is mounted on slide plate 2. A lead screw 13 is mounted on the output end of the second motor 15. Slide rails 11 are located on both sides of the lead screw 13 on slide plate 2. A slider 10 and a nut seat 12 are located at the bottom of slide table 3. Slide table 3 is mounted on slide plate 2 through the interaction of the slider 10 and nut seat 12 with the slide rails 11 and the lead screw 13 of the second motor 15, thus limiting its movement. By mounting the second motor and lead screw on the slide plate, two-stage transmission control of the slide table is achieved. This design allows the slide table to not only move on the slide plate but also flexibly change its speed and direction by adjusting the speed and direction of the second motor. The cooperation of the lead screw and nut seat ensures high-precision linear motion of the slide table on the slide plate. The slide rail provides stable guidance, effectively preventing the slide table from shifting and shaking during movement, thus ensuring the accuracy and stability of the machining. The cutter head 4 is movably mounted on the base plate 1 above the slide table 3 via the frame 8.

[0036] Example 2

[0037] To facilitate the adjustment of the angle of the cutter head 4, for example, as shown... Figures 1 to 4As shown, the present invention further includes: a third motor 16 mounted on a frame 8, a lead screw 13 mounted on the output end of the third motor 16, slide rails 11 mounted on both sides of the lead screw 13 on the frame 8, a mounting plate 9 mounted on the frame 8 via the lead screw 13 and slide rails 11, a slider 10 and a nut seat 12 provided on the mounting plate 9, the mounting plate 9 being limited and mounted on the frame 8 by the slider 10 and nut seat 12 cooperating with the slide rails 11 and the lead screw 13 of the third motor 16, and a second adjustment mechanism slidably mounted on the mounting plate 9 via a limiting plate 7. The second adjusting seat 6 has a first sliding groove 701 on the limiting plate 7 and a pin 602 on the limiting plate 7. The second adjusting seat 6 is rotatably mounted on the limiting plate 7 via the pin 602, and a fixing bolt 17 is provided on the second adjusting seat 6. The second adjusting seat 6 slides longitudinally between the limiting plate 7 with the pin 602 as the center, via the fixing bolt 17 and the first sliding groove 701. This design allows the second adjusting seat to slide longitudinally on the limiting plate with the pin as the center, thus facilitating the adjustment of the angle and position of the second adjusting seat. This flexibility allows the lathe to handle workpieces of different shapes and sizes, improving the adaptability and flexibility of machining. The cooperation between the pin and the limiting plate provides stable support for the second adjusting seat, ensuring its stability and reliability during adjustment. This stability helps reduce vibration and errors during machining, improving machining efficiency and quality. A first adjusting seat 5 is slidably mounted on the second adjusting seat 6. The second adjusting seat 6 has a protrusion 601, and the first adjusting seat 5 has a second sliding groove 501. A rotating seat is located below the second sliding groove 501 on the first adjusting seat 5. The first adjusting seat 5 is rotatably connected to the second adjusting seat 6 via the rotating seat, and a fixing bolt 17 is also installed on the second adjusting seat 6 at the second sliding groove 501. The first adjusting seat 5 slides laterally on the second adjusting seat 6 with the rotating seat as the center, via the second sliding groove 501 and the fixing bolt 17. This design allows the first adjusting seat to slide laterally on the second adjusting seat. Combined with the longitudinal sliding of the second adjusting seat on the limiting plate, it achieves omnidirectional adjustment of the first adjusting seat in three-dimensional space. This multi-dimensional adjustment capability enables the lathe to handle more complex and precise machining needs, improving machining flexibility and adaptability. Precise adjustment of the angle and position of the first adjusting seat can be achieved through precise adjustment of the fixing bolt within the second sliding groove. This high-precision positioning capability is crucial for ensuring machining accuracy and workpiece quality, and helps to reduce machining errors and improve machining efficiency. The first adjusting seat 5 is fixed with the cutting head 4.

[0038] Working principle:

[0039] The first motor 14 drives the lead screw 13 to rotate. The lead screw 13 cooperates with the nut seat 12 on the slide plate 2. When the lead screw 13 rotates, the nut seat 12 drives the slide plate 2 to slide along the slide rail 11 on the base plate 1, realizing the longitudinal movement of the slide plate 2.

[0040] The second motor 15 drives the lead screw 13 to rotate. Through the cooperation between the nut seat 12 and the slide table 3, when the lead screw 13 rotates, the slide table 3 slides on the slide plate 2 along the slide rail 11, realizing the lateral movement of the slide table 3.

[0041] The third motor 16 is mounted on the frame 8 and drives another lead screw 13 to rotate. Through the cooperation between the nut seat 12 and the mounting plate 9, when the lead screw 13 rotates, the mounting plate 9 slides along the slide rail 11 on the frame 8, realizing the lifting and lowering movement of the mounting plate 9.

[0042] The slide rails 11 are provided on the base plate 1, the slide plate 2, and the frame 8, providing stable guidance for the movement of the slide plate 2, the slide table 3, and the mounting plate 9. The cooperation between the slider 10 and the slide rails 11 ensures the stability and accuracy of each component during movement.

[0043] The pin 602 is rotatably connected to the limiting plate 7, and can slide longitudinally around the pin 602 within the first groove 701 of the limiting plate 7. By adjusting the tightness of the fixing bolt 17, the deflection angle of the second adjusting seat 6 can be changed, thereby adjusting the longitudinal angle of the cutter head 4.

[0044] The rotating seat is rotatably connected to the second adjusting seat 6, and can slide laterally around the rotating seat as the center within the second slide groove 501 of the second adjusting seat 6. Similarly, by adjusting the tightness of the fixing bolt 17, the deflection angle of the first adjusting seat 5 can be changed, thereby achieving the adjustment of the lateral angle of the cutter head 4.

[0045] The cutter head 4 is fixed on the first adjusting seat 5. With the deflection of the first adjusting seat 5 and the second adjusting seat 6, and the movement of the mounting plate 9, the slide 3 and the sliding plate 2, the cutter head 4 can be precisely positioned and adjusted in three-dimensional space. This design allows the cutter head 4 to flexibly adapt to the machining needs of workpieces of different shapes and sizes.

[0046] In summary, this lathe's tool path structure achieves precise control of the tool head 4 in three-dimensional space through the coordinated operation of multiple aspects, including the motor-driven lead screw 13, the guide rail 11, and the deflection of the adjusting seat. The operator can control the movement trajectory and cutting force of the tool head 4 by adjusting parameters such as the motor speed, the position of the guide rail 11, and the deflection angle of the adjusting seat, thereby achieving precise machining of the workpiece.
