Technical Field
[0001] This invention relates to the field of turning technology, specifically to thermally compensated high-rigidity horizontal turning center equipment and its application. Background Technology
[0002] Turning is a machining process in which a cutting tool is used to cut a rotating workpiece; it belongs to lathe machining. This process utilizes the coordination between the workpiece's rotation and the linear or curvilinear motion of the cutting tool. By changing tools such as drills, reamers, and boring tools, drilling and reaming can be performed. It can machine internal and external cylindrical surfaces, end faces, conical surfaces, and threads, and is suitable for manufacturing shafts, discs, and sleeves.
[0003] Patent application number CN202211680923.7 discloses a horizontal lathe grinding device, including a horizontal lathe with a bed, chuck, and a carriage, and a mounting block clamped on the carriage; a grinding wheel rotatably mounted on the mounting block via a shaft; a rotating mechanism mounted on the mounting block for driving the shaft and grinding wheel to rotate, and a locking component for locking the shaft on the mounting block; and an anti-wear mechanism including a cleaning section and a blowing section. The cleaning section includes a rotating frame, a brush, and a driving component for driving the rotating frame to rotate. The brush is mounted on the inner side of the rotating frame. The blowing section includes an air supply component and an air jet component. The air supply component is mounted on the carriage, and the air jet component and the air supply component are rotatably connected, and the air jet component and the rotating frame are drively connected. This invention achieves the effect of grinding using a horizontal lathe and facilitates the handling of grinding debris.
[0004] Current mainstream solutions generally only consider the treatment of machining debris. However, when machining high-rigidity shaft parts, if the cutting tool is subjected to excessive pressure, the turret will become unstable and prone to vibration, resulting in reduced machining accuracy. At the same time, when processing long shaft workpieces, the workpiece is too long and will deform due to heat during the machining process, which will also lead to reduced machining accuracy.
[0005] In view of this, we propose a thermally compensated high-rigidity horizontal turning center and its application. Summary of the Invention
[0006] In order to overcome the defects in the prior art, the purpose of this invention is to provide a thermally compensated high-rigidity horizontal turning center and its application. The cutting tool is compressed, causing the disc spring assembly to deform, which causes the tower base to be clamped and fixed on the first slide by the clamping arm. At the same time, the auxiliary compensation component slides, providing a fulcrum for machining long shaft workpieces, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides a thermally compensated high-rigidity horizontal turning center and its application, including a lathe, a turret assembly and an auxiliary compensation assembly slidably connected to the lathe, and a cleaning assembly installed on the lathe. The lathe has a chuck and a rear support at both ends on the same axis, and the lathe has a slide rail. The turret assembly slides to drive the cleaning assembly to work.
[0008] The turret assembly includes a first slide block slidably connected to the slide rail, a turret base slidably connected to the top of the first slide block, a cutting tool mounted on the top of the turret base, and a clamping device mounted on the turret base. The cutting tool experiences increased force, and the clamping device clamps the first slide block. The clamping device includes a tool holder movably inserted into the top of the turret base, a double-sided rack block welded and fixed to the center of the bottom surface of the tool holder, a butterfly spring assembly sleeved on the upper end of the double-sided rack block, two gear blocks rotatably connected to both sides of the rack block, and a clamping arm rotatably connected to the outside of the gear blocks. The gear blocks mesh with the double-sided rack block, and the end of the gear block is slidably connected to the end of the clamping arm. The tool holder moves downward so that the clamping arm clamps onto the first slide block.
[0009] The auxiliary compensation component includes a second slide block slidably connected to the slide rail, a collar welded and fixed to the top of the second slide block, and several fixed posts threadedly connected to the collar and pointing to its center.
[0010] This design takes into account that during the machining of high-rigidity shaft parts, excessive pressure on the cutting tool can cause vibration of the tower base during machining, leading to a decrease in machining accuracy. When the cutting tool is subjected to significant pressure during cutting, this pressure is transmitted to the disc spring assembly, causing it to deform. This deformation, in turn, causes the double-sided rack block to press down. The pressing action of the double-sided rack block drives the meshing gear block to rotate. The rotation of the gear block, in turn, drives the clamping arm to rotate, and then the bottom end moves towards the first slide block and finally clamps it. This effectively prevents vibration of the tower base caused by excessive force, ensuring the stability and accuracy of the machining process.
[0011] Meanwhile, the auxiliary compensation component is designed to address the deformation problem of long shaft workpieces caused by heat during machining. When machining long shaft workpieces, the second slide can be slid to a suitable position according to the actual length and deformation of the workpiece, and the fixed column can be rotated to make it fit tightly against the workpiece, providing an additional support point for the workpiece. In this way, even if the workpiece deforms due to heat during machining, the adjustment of the auxiliary compensation component can maintain the stability of its relative position and shape, thereby further improving machining accuracy.
[0012] In addition, the design of the cleaning component effectively solves the problem of debris generated during the processing.
[0013] As a further improvement to this technical solution, a first threaded rod is rotatably connected to one side of the slide rail, the first threaded rod is threadedly connected to the first slide block, and a first motor is installed on one side of the lathe, the output shaft of the first motor is coaxially connected to the first threaded rod.
[0014] This setup uses a first motor to drive a first threaded rod to rotate, which in turn causes a first slide block, threadedly connected to the first threaded rod, to move precisely in a straight line along a slide rail. This design not only achieves precise horizontal positioning of the turret assembly but also ensures that the turret assembly can be quickly and accurately adjusted in position as needed during machining, thereby improving machining efficiency.
[0015] As a further improvement to this technical solution, the cleaning assembly includes a bidirectional lead screw and a slide rod rotatably connected to both ends of the lathe, and a cleaning brush slidably connected between them. One end of the cleaning brush is threadedly connected to the bidirectional lead screw, and one end of the bidirectional lead screw is provided with a second bevel gear. A first bevel gear is provided on the first threaded rod, and the second bevel gear and the first bevel gear are connected by a bevel gear transmission.
[0016] This design uses the rotation of the first threaded rod to drive the first bevel gear, which in turn transmits power to the second bevel gear via the bevel gear assembly, causing the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw drives the cleaning brush, which is threadedly connected to it, to reciprocate linearly along the slide bar, thus automatically cleaning debris from the lathe surface. Maintaining the cleanliness of the lathe helps extend its service life.
[0017] As a further improvement to this technical solution, a T-shaped slider is welded and fixed at the center of the bottom end of the tower base. The top of the first slider is provided with a groove that matches the size of the T-shaped slider. A second threaded rod is rotatably connected in the groove. A second motor is installed on one side of the first slider. The output shaft of the second motor is coaxially connected to the second threaded rod. A threaded hole that matches the second threaded rod is provided on the T-shaped slider.
[0018] This design utilizes a second motor to drive a second threaded rod to rotate, which in turn causes a T-shaped slider, threadedly connected to the second threaded rod, to move precisely in a straight line along the slide groove. This design not only achieves precise positioning of the tower base on the first slide but also allows the tower base to be flexibly adjusted according to processing requirements, thereby improving processing flexibility and accuracy. Simultaneously, the cooperative design between the T-shaped slider and the slide groove enhances the connection stability between the tower base and the first slide, further ensuring a smooth processing procedure.
[0019] As a further improvement to this technical solution, a third threaded rod is rotatably connected to the other side of the slide rail. The third threaded rod is threadedly connected to the second slide block. A third motor is installed on one side of the lathe, and the output shaft of the third motor is coaxially connected to the third threaded rod.
[0020] This setup uses a third motor to drive the third threaded rod to rotate, which in turn drives the second slide block, which is threaded to the third threaded rod, to move precisely in a straight line along the slide rail. This design allows the auxiliary compensation component to be quickly and accurately adjusted to the appropriate position according to the actual length and deformation of long shaft workpieces, providing a stable fulcrum for the workpiece. This effectively solves the problem of deformation caused by heat during the processing of long shaft workpieces, further improving processing accuracy and stability.
[0021] As a further improvement to this technical solution, the end of the gear block is integrally formed with a sliding column, and the clamping arm is provided with an elongated hole that matches the sliding column.
[0022] This design achieves stable transmission between the gear block and the clamping arm through the sliding engagement of the sliding column and the elongated hole. When the gear block rotates under the drive of the double-sided rack block, the sliding column slides in the elongated hole, thereby driving the clamping arm to perform precise rotation and clamping actions. This design not only ensures the flexibility and stability of the clamping arm, but also improves the transmission efficiency and reliability of the entire clamping device, effectively preventing vibration of the tower base due to excessive force during processing, and ensuring the stability of processing accuracy.
[0023] As a further improvement to this technical solution, a clamping block is hinged to the bottom end of the clamping arm, and a soft rubber pad is adhered and fixed to the outer wall of the clamping block.
[0024] This design involves hinged clamping blocks at the bottom of the clamping arm and adhesive-fixed soft rubber pads to the outer wall of the clamping blocks. When the clamping arm grips the first slide, the soft rubber pads act as cushioning and friction enhancers. On one hand, the soft rubber pads reduce rigid collisions between the clamping arm and the first slide, lowering noise generated by vibration during operation. They also help protect the surfaces of the first slide and the clamping arm, reducing wear and extending the equipment's lifespan. On the other hand, the soft rubber pads increase the friction between the clamping arm and the first slide, making the clamping more stable and reliable. This further prevents vibration of the tower base due to excessive force during processing, thus ensuring the stability and accuracy of the processing. This design fully considers the needs of actual processing, improving the overall performance and reliability of the equipment.
[0025] As a further improvement to this technical solution, the collar is provided with a plurality of threaded seats that are adapted to the size of the fixed post, and the outer wall of the fixed post is provided with an external thread that is adapted to the internal thread of the threaded seat.
[0026] This design achieves a stable threaded connection between the fixed post and the collar by creating a threaded seat on the collar that matches the size of the fixed post, and an external thread on the outer wall of the fixed post that matches the internal thread of the threaded seat. This design allows the fixed post to be flexibly adjusted in position on the collar as needed, and by rotating the fixed post, it can be brought into close contact with long shaft-like workpieces, providing a stable fulcrum for the workpiece. During machining, when long shaft-like workpieces deform due to heat, the deformation can be compensated by adjusting the position of the fixed post, thereby maintaining the stability of the workpiece's relative position and shape, effectively solving the problem of reduced machining accuracy caused by heat deformation of long shaft-like workpieces during machining.
[0027] As a further improvement to this technical solution, collection boxes are installed on both sides of the lathe, and reinforcing ribs are welded and fixed at the four corners of the lathe.
[0028] This design, by installing collection boxes on both sides of the lathe, effectively collects and cleans debris and waste generated during the machining process, preventing debris from scattering around the lathe and maintaining a clean working environment. Simultaneously, reinforcing ribs welded to the four corners of the lathe enhance its overall structural strength and stability. When machining high-rigidity shaft parts, the lathe needs to withstand significant cutting forces and vibrations. The reinforcing ribs effectively disperse and bear these forces, preventing deformation or damage due to excessive stress, thus ensuring smooth machining and stable machining accuracy.
[0029] This thermally compensated high-rigidity horizontal turning center is used in the machining of high-rigidity shaft parts.
[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0031] 1. This thermally compensated high-rigidity horizontal turning center equipment and its application, through the unique design of the clamping fastener in the turret assembly, when the cutting tool is subjected to increased force, the clamping fastener can effectively clamp the first slide, preventing the turret from vibrating due to excessive force, thus ensuring the stability and accuracy of the machining process.
[0032] 2. This thermally compensated high-rigidity horizontal turning center equipment and its application, through the set auxiliary compensation components, can slide the second slide to a suitable position according to the actual length and deformation of the workpiece during machining, and make it close to the workpiece by rotating the fixed column, providing an additional support point for the workpiece, maintaining the relative position and shape stability of the workpiece, and further improving the machining accuracy.
[0033] 3. The thermally compensated high-rigidity horizontal turning center equipment and its application achieve automatic cleaning of lathe surface debris through the design of the cleaning component. The rotation of the first threaded rod drives the first bevel gear to rotate, which in turn transmits power to the second bevel gear to rotate the bidirectional screw, driving the cleaning brush to reciprocate along the slide bar, thus keeping the lathe clean.

However, the specific embodiments of the present invention described herein are for illustrative purposes only and should not be construed as limiting the invention in any way. Under the teachings of this invention, those skilled in the art can conceive of any possible modifications based on the invention, and these should all be considered to fall within the scope of the invention. The terms "installation" and "connection" should be interpreted broadly, referring to direct connection or indirect connection through an intermediate medium.

Furthermore, in the description of the invention, "a number" means two or more, unless otherwise explicitly specified.
[0054] Please see Figures 1-8 As shown, this invention provides a thermally compensated high-rigidity horizontal turning center for use in machining high-rigidity shaft parts. It includes a lathe 100, a turret assembly 400 and an auxiliary compensation assembly 800 slidably connected to the lathe 100, and a cleaning assembly 500 mounted on the lathe 100. The lathe 100 has a chuck 110 and a rear support 120 at both ends on the same axis. The lathe 100 has a slide rail 130. The turret assembly 400 slidably drives the cleaning assembly 500 to operate.
[0055] Specifically, collection boxes 140 are installed on both sides of the lathe 100, and reinforcing ribs 150 are welded and fixed at each of the four corners of the lathe 100. The collection boxes 140 are designed to collect the debris generated during the machining process swept off by the cleaning component 500, preventing debris from scattering in the work area, helping to maintain a clean working environment, and reducing potential safety hazards caused by debris accumulation. The reinforcing ribs 150 welded and fixed at the four corners of the lathe 100 greatly enhance the overall structural strength of the lathe 100. During the machining of high-rigidity shaft parts, the lathe 100 needs to withstand large cutting forces and vibrations. The reinforcing ribs 150 can effectively disperse and bear these forces, preventing the lathe 100 from deforming or being damaged due to excessive force, thereby ensuring the smooth progress of the machining process and the stability of machining accuracy.
[0056] The turret assembly 400 includes a first slide block 410 slidably connected to the slide rail 130, a turret base 420 slidably connected to the top of the first slide block 410, a cutter 450 mounted on the top of the turret base 420, and a clamping device 460 mounted on the turret base 420. The cutter 450 experiences increased force, and the clamping device 460 clamps the first slide block 410. The clamping device 460 includes a cutter holder 461 movably inserted into the top of the turret base 420, a double-sided rack block 462 welded and fixed to the center of the bottom surface of the cutter holder 461, a butterfly spring assembly 463 sleeved on the upper end of the double-sided rack block 462, two gear blocks 464 rotatably connected to both sides of the double-sided rack block 462, and a clamping arm rotatably connected to the outside of the gear blocks 464. 465; Gear block 464 meshes with double-sided rack block 462. The end of gear block 464 is slidably connected to the end of clamping arm 465. The tool holder 461 moves down so that the clamping arm 465 is clamped on the first slide block 410. The tool holder 461 in the clamping device 460 drives the double-sided rack block 462 to move downward. The racks on both sides of the double-sided rack block 462 mesh with the two gear blocks 464 respectively, so that the two gear blocks 464 rotate. The end of the gear block 464 drives the clamping arm 465 to rotate. The bottom end of the clamping arm 465 is in close contact with the first slide block 410 for clamping and fixing, effectively preventing the tower base 420 from vibrating due to excessive force on the cutting tool 450, and ensuring the stability and accuracy of the machining process;
[0057] Please see Figure 6As shown, the auxiliary compensation component 800 includes a second slide block 810 slidably connected to the slide rail 130, a collar 820 welded and fixed to the top of the second slide block 810, and several fixed posts 830 threadedly connected to the collar 820 and pointing towards its center. The second slide block 810 can slide along the slide rail 130 to a suitable position according to the actual length and deformation of the long shaft workpiece, providing a stable fulcrum for the workpiece. When the long shaft workpiece deforms due to heat during processing, the fixed posts 830 can be rotated to fit tightly against the workpiece surface, effectively compensating for the workpiece deformation, maintaining the relative position and shape stability of the workpiece, and further improving processing accuracy and stability.
[0058] For further details, please refer to Figure 6 As shown, the collar 820 has several threaded seats 821 that are adapted to the size of the fixed post 830. The outer wall of the fixed post 830 has external threads that are adapted to the internal threads of the threaded seats 821. This design makes the connection between the fixed post 830 and the collar 820 both stable and flexible. In actual machining, the operator can adjust the position of the fixed post 830 on the collar 820 by rotating it according to the specific size and degree of deformation of the long shaft workpiece, thereby ensuring that the fixed post 830 can fit tightly against the workpiece surface and provide stable and reliable support for the workpiece. This adjustable support method effectively solves the problem of decreased machining accuracy caused by workpiece thermal deformation and improves the stability and reliability of the machining process.
[0059] For details, please refer to Figure 2 As shown, a first threaded rod 200 is rotatably connected to one side of the slide rail 130. The first threaded rod 200 is threadedly connected to the first slide block 410. A first motor 300 is installed on one side of the lathe 100. The output shaft of the first motor 300 is coaxially connected to the first threaded rod 200. When the first motor 300 is started, its output shaft drives the first threaded rod 200 to rotate. Since the first threaded rod 200 and the first slide block 410 are threadedly connected, the rotation of the first threaded rod 200 will drive the first slide block 410 to slide linearly along the slide rail 130, so that the turret assembly 400 can be precisely positioned and moved on the lathe 100 to meet the needs of different machining positions.
[0060] In addition, please see Figure 2As shown, a third threaded rod 600 is rotatably connected to the other side of the slide rail 130. The third threaded rod 600 is threadedly connected to the second slide block 810. A third motor 700 is installed on one side of the lathe 100. The output shaft of the third motor 700 is coaxially connected to the third threaded rod 600. When the third motor 700 is started, its output shaft drives the third threaded rod 600 to rotate. Since the third threaded rod 600 and the second slide block 810 are threadedly connected, the rotation of the third threaded rod 600 will drive the second slide block 810 to slide linearly along the slide rail 130. This allows the auxiliary compensation component 800 to be flexibly positioned and moved on the lathe 100, thereby accurately adjusting the position of the second slide block 810 according to the actual length and deformation of the long shaft workpiece, providing a stable fulcrum for the workpiece.
[0061] For further details, please refer to Figure 5 and Figure 7 As shown, the cleaning assembly 500 includes a bidirectional lead screw 520 and a slide bar 530 rotatably connected to both ends of the lathe 100, and a cleaning brush 510 slidably connected between them. One end of the cleaning brush 510 is threadedly connected to the bidirectional lead screw 520. A second bevel gear 521 is provided at one end of the bidirectional lead screw 520, and a first bevel gear 210 is provided on the first threaded rod 200. The second bevel gear 521 and the first bevel gear 210 are connected by a bevel gear component 540. When the first motor 300 drives the first threaded rod 200 to rotate, it not only drives the turret assembly 400 to move, but also the first bevel gear 210 on the first threaded rod 200 rotates accordingly. The first bevel gear 210 transmits power to the second bevel gear 521 through the bevel gear component 540, thereby driving the bidirectional lead screw 520 to rotate. Since one end of the cleaning brush 510 is threadedly connected to the bidirectional lead screw 520, the cleaning brush 510 will reciprocate linearly along the slide bar 530 under the rotation of the bidirectional lead screw 520, thus realizing the automatic cleaning of the surface of the lathe 100 by the cleaning brush 510, effectively avoiding the interference of the debris to the machining process and keeping the lathe 100 clean.
[0062] For details, please refer to Figure 3As shown, a T-shaped slider 421 is welded and fixed at the center of the bottom end of the tower base 420. A groove matching the size of the T-shaped slider 421 is opened at the top of the first slide block 410. A second threaded rod 430 is rotatably connected within the groove. A second motor 440 is installed on one side of the first slide block 410. The output shaft of the second motor 440 is coaxially connected to the second threaded rod 430. A threaded hole matching the second threaded rod 430 is opened on the T-shaped slider 421. When the second motor 440 is started, its output shaft drives the second... As the threaded rod 430 rotates, the T-shaped slider 421, with its threaded hole matching the second threaded rod 430 and slidably connected to the groove at the top of the first slide block 410, drives the T-shaped slider 421 to slide linearly along the groove. This, in turn, causes the tower 420 to be precisely positioned and moved on the first slide block 410, allowing the cutting tool 450 to flexibly adjust its position on the lathe 100 according to different machining requirements. Simultaneously, the design of the T-shaped slider 421 and the groove ensures the stability and accuracy of the tower 420 during movement.
[0063] It is worth noting that, please refer to Figure 4 As shown, the end of the gear block 464 is integrally formed with a sliding column 4641, and the clamping arm 465 has an elongated hole 4651 adapted to the sliding column 4641. The sliding column 4641 is slidably connected in the elongated hole 4651. This structural design allows the gear block 464 to drive the clamping arm 465 to rotate accordingly through the sliding column 4641 when it rotates. When the tool holder 461 moves down, the double-sided rack block 462 moves down accordingly, and the racks on both sides of it mesh with the two gear blocks 464 respectively, causing the gear blocks 464 to rotate. Then, through the sliding of the sliding column 4641 in the elongated hole 4651, the clamping arm 465 rotates and makes close contact with the first slide block 410, thus achieving a stable clamping of the first slide block 410.
[0064] For further details, please refer to Figure 4 As shown, a clamping block 466 is hinged to the bottom end of the clamping arm 465. A soft rubber pad is adhered and fixed to the outer wall of the clamping block 466. The soft rubber pad can effectively increase the friction between the clamping block 466 and the first slide block 410, ensuring the stability of the clamping, and at the same time, it can prevent the clamping block 466 from damaging the surface of the first slide block 410 during the clamping process.
[0065] In operation, the high-rigidity horizontal turning center equipment with thermal compensation of the present invention and its application firstly install the high-rigidity shaft part to be processed between the chuck 110 and the rear support 120 at both ends of the lathe 100 to ensure that the part is fixed and stable. Then, the first motor 300 is started, and the output shaft of the first motor 300 drives the first threaded rod 200 to rotate. The rotation of the first threaded rod 200 drives the first slide block 410 to slide linearly along the slide rail 130, so that the turret assembly 400 moves to the appropriate processing position. At the same time, the first bevel gear 210 on the first threaded rod 200 also rotates, and the power is transmitted to the second bevel gear 521 through the bevel gear component 540, which in turn drives the double-acting screw 520 to rotate. Under the action of the rotation of the double-acting screw 520, the cleaning brush 510 moves linearly back and forth along the slide bar 530 to clean the surface of the lathe 100 and avoid the debris from interfering with subsequent processing.
[0066] Once the turret assembly 400 has moved to the appropriate position, the second motor 440 is activated. The output shaft of the second motor 440 drives the second threaded rod 430 to rotate. The rotation of the second threaded rod 430 drives the T-shaped slider 421 at the bottom of the turret base 420 to slide linearly along the groove at the top of the first slide block 410, thereby enabling the turret base 420 to be precisely positioned and moved on the first slide block 410, so that the cutting tool 450 reaches the designated machining point. During the machining process, as the cutting tool 450 is subjected to excessive force, the tool holder 461 compresses the butterfly spring assembly 463, causing it to deform and drive the double-sided rack block 462 to move downward. The racks on both sides of the double-sided rack block 462 mesh with two gear blocks 464 respectively, causing the gear blocks 464 to rotate. The end of the gear block 464 drives the clamping arm 465 to rotate through the sliding of the sliding column 4641 in the elongated hole 4651. The clamping block 466 at the bottom of the clamping arm 465 is in close contact with the first slide block 410, achieving a stable clamping of the first slide block 410. This effectively prevents the tower base 420 from vibrating due to excessive force on the cutting tool 450, ensuring the stability and accuracy of the machining process.
[0067] For long-shaft workpieces, deformation may occur due to heat during machining. At this time, the third motor 700 is started, and its output shaft drives the third threaded rod 600 to rotate. The rotation of the threaded rod 600 drives the second slide block 810 to slide linearly along the slide rail 130, moving the auxiliary compensation component 800 to a suitable position. Then, the fixed post 830 on the rotating collar 820 is made to fit tightly against the workpiece surface, providing a stable fulcrum for the workpiece, effectively compensating for its deformation and maintaining its relative position and shape stability. Throughout the machining process, the collection boxes 140 on both sides of the lathe 100 collect the machining debris swept off by the cleaning component 500.
