Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically a Swiss-type lathe for machining bar workpieces. Background Technology

[0002] In the machining industry, Swiss-type lathes are widely used precision machining equipment, and their processing capabilities directly affect the adaptability of product production. With the evolution of market demands, the demand for products with specific diameter specifications is showing a significant upward trend, especially for small-diameter bar stock processing. The order volume for φ4 and φ6 specifications has seen particularly significant growth, becoming core specifications that current production needs to focus on. This change in demand places more precise and comprehensive requirements on the processing range of Swiss-type lathes, necessitating equipment with the ability to stably process two types of small-diameter products simultaneously.

[0003] The current 20-type Swiss-type headstock lathe, while capable of processing φ6 products, cannot meet the processing demands for φ4 products, and its overall processing efficiency is far from keeping pace with the increasing order volume, indicating a significant limitation in the equipment's processing capacity. If the existing Swiss-type headstock lathe is not upgraded, and the processing gap is only addressed by purchasing new equipment, this will substantially increase equipment investment costs, contradicting the industry's generally promoted cost reduction and efficiency improvement production philosophy. Therefore, there is an urgent need to develop a Swiss-type headstock lathe for processing bar stock workpieces, overcoming the limitations of existing equipment, improving the processing capacity of the Swiss-type headstock lathe, and achieving efficient processing of φ4 and φ6 products, thereby meeting market demands. Summary of the Invention

[0004] This utility model addresses the shortcomings and deficiencies of existing technologies by providing a Swiss-type lathe for processing bar workpieces. Through ingenious design of the feeding mechanism and tooling components, it overcomes the processing limitations of existing equipment, can simultaneously meet the processing needs of bars with different diameters, and improves processing adaptability and stability.

[0005] To achieve the above objectives, this utility model provides a Swiss-type lathe for processing bar workpieces, comprising a feeder spindle, a limit fixture assembly, and a feeding mechanism. The feeding mechanism includes a push rod, a centering mechanism, and a flow-guiding nylon sleeve. The limiting tooling assembly includes a feeder clamp and a spindle clamp, which are sleeved on the outside of the bar stock to limit and prevent vibration of the bar stock. The feed clamp of the feeder is fixedly connected to the feed inlet end of the feeder main shaft. The spindle clamp is an elastic clamp, specifically including a telescopic clamp body. One end of the telescopic clamp body is connected to the discharge end of the guide nylon sleeve, and the other end is connected to the feed end of the feeder clamp. The bar stock passes sequentially through the centering mechanism, the guide nylon sleeve, the telescopic clamp, and the feeder clamp, and connects to the feeder main shaft.

[0006] Preferably, the telescopic clamp is an elastic telescopic body, specifically a short compression spring with an elastic elongation of 25mm.

[0007] Preferably, the feed end opening of the flow-guiding nylon sleeve is a large-tapered conical surface inclined from the outer side wall to the inner side wall, and the inclination angle of the large-tapered conical surface is 45°-65°.

[0008] Preferably, the material clamp of the feeder is a hollow joint structure composed of a straight cylindrical section and a stepped cylindrical section, with the stepped cylindrical section directly connected to the main shaft of the feeder; The outer diameter of the stepped cylindrical section is larger than the diameter of the straight cylindrical section.

[0009] Preferably, the maximum outer diameter of the stepped cylindrical section is 18 mm, and the maximum outer diameter of the straight cylindrical section is 13 mm.

[0010] Preferably, the centering mechanism includes a first cylinder, a centering frame, and a shock-absorbing wheel; the base of the first cylinder is connected to the frame of the Swiss-type machine through a cylinder fixing plate; the telescopic rod of the first cylinder passes through the cylinder fixing plate and is fixedly connected to the centering frame. The centering frame is a heart-shaped support frame with an opening at the bottom. Shock-absorbing wheels are symmetrically installed on the left and right sides of the bottom of the centering frame. The two shock-absorbing wheels are located on the same horizontal plane, and the distance between them is less than the outer diameter of the material bar. The first cylinder extends and retracts, driving the centering frame to move up and down, thereby adjusting the height of the centering frame and ultimately controlling the two anti-vibration wheels to center, guide, and support the material bars of different outer diameters passing through the middle of the centering frame.

[0011] Preferably, the first cylinder is a short-stroke secondary anti-vibration wheel cylinder, and the centering frame has a horizontally arranged movable shaft at the top center. The telescopic rod of the first cylinder passes through the cylinder fixing plate and is fixedly connected to the movable shaft at the top of the centering frame. By extending and retracting the first cylinder, the movable shaft and the centering frame move up and down, and finally control the two anti-vibration wheels to center and guide the material bars of different outer diameter sizes passing through the middle of the centering frame.

[0012] Preferably, the push rod, anti-vibration bushing, centering mechanism, guide nylon sleeve, feeder clamp and main shaft clamp are located on the same axis as the feeder main shaft.

[0013] Preferably, the push rod is fitted with an anti-vibration bushing, which is a multi-segment combination structure, and multiple anti-vibration bushings are joined at their ends and can be rotatably fitted onto the outside of the push rod.

[0014] Preferably, the interior of the anti-vibration bushing is a channel that matches the outer diameter of the push rod, and the outer side of the anti-vibration bushing is a cone structure with a large outer diameter in the middle and a gradually decreasing outer diameter towards the left and right ends.

[0015] The present invention provides a Swiss-type headstock machining center for processing bar stock. It has the following advantages: This utility model relates to a Swiss-type headstock machining center for processing bar stock. Its structure is simple and ingenious. Through clever design of the elastic telescopic allowance of the main spindle clamp, the combination of stepped and straight cylindrical feeders, and the centering mechanism, it can flexibly adapt to the clamping requirements of bars with different diameters. This ensures the feasibility of processing new diameter ranges, enabling the 20-type Swiss-type headstock to process bars with diameters from φ4 to φ20 and the 32-type to process bars with diameters from φ6 to 32. This completely breaks through previous limitations, better adapting to diverse market demands and expanding market reach.

[0016] Meanwhile, the addition of an anti-vibration bushing to the outside of the push rod, the adoption of a short feed outlet baffle spring, an increased taper of the guide nylon sleeve, and the use of a short-stroke secondary anti-vibration wheel cylinder effectively reduce the vibration and swaying of the bar stock during feeding and processing, ensuring precise guidance for bars of different diameters. This avoids feed deviation and wear of thinner bars while reducing the guide resistance of bars of different diameters. Through improvements and optimizations to the tooling and tool holder assembly, the force is more uniform during processing, significantly reducing the risk of workpiece deformation and breakage, improving processing accuracy, and enhancing the quality of new specification processed products.

[0017] Finally, the optimized Swiss-type lathe of this invention significantly reduces costs. Compared to purchasing new equipment, it significantly reduces investment costs, aligning with the concept of cost reduction and efficiency improvement, and further enhancing market competitiveness while improving capabilities and quality.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Please see Figures 1-6 The Swiss-type lathe for processing bar stock provided by this utility model includes a feeder spindle 1, a limiting fixture assembly, and a feeding mechanism; the feeding mechanism includes a pusher rod 6, a centering mechanism 3, and a guide nylon sleeve 4. The limiting fixture assembly includes a feeder clamp 5 and a spindle clamp, which are sleeved on the outside of the bar stock for limiting and shockproofing the bar stock.

[0023] The feeder clamp 5 is fixedly connected to the feed inlet end of the feeder main shaft 1. The main shaft clamp is an elastic clamp, specifically including a telescopic clamp body 2. One end of the telescopic clamp body 2 is connected to the discharge end of the guide nylon sleeve 4, and the other end is connected to the feed inlet end of the feeder clamp 5. The bar stock passes sequentially through the centering mechanism 3, the guide nylon sleeve 4, the telescopic clamp body 2, and the feeder clamp 5, and connects to the feeder main shaft 1. The feeder clamp 5 is a hollow joint structure composed of a straight cylindrical section and a stepped cylindrical section. The stepped cylindrical section is directly connected to the feeder main shaft 1, ensuring that the axis of the feeder clamp 5 coincides with that of the main shaft clamp 2.

[0024] The outer diameter of the stepped cylindrical section is larger than the diameter of the straight cylindrical section. Preferably, the maximum outer diameter of the stepped cylindrical section is 18 mm, and the maximum outer diameter of the straight cylindrical section is 13 mm.

[0025] This utility model relates to a Swiss-type headstock machining center. Through ingenious design of the elastic telescopic body extension allowance of the main spindle clamp, the feeder clamp combining stepped and straight sections, and the centering mechanism, it achieves flexible adaptation to the clamping requirements of bars with different diameters, ensuring the feasibility of processing new diameter ranges. This allows the 20-type Swiss-type headstock to process bars with diameters of φ4-φ20 and the 32-type to process bars with diameters of φ6-32, completely breaking through the original limitations and better adapting to the diversified market demands and expanding market space.

[0026] The telescopic clamp 2 is an elastic telescopic body, specifically a short compression spring with an elastic elongation of 25mm. The free length of the short free-length spring needs to be set according to the assembly space of the outlet baffle of the Swiss-type headstock and the pushing requirements of the thin bar stock, to adapt to the pushing force range of φ4-φ6 thin bar stock. The elastic telescopic body can buffer the clamping force through its own deformation, avoiding bar deformation caused by rigid clamping, while ensuring clamping firmness. During assembly, connect both ends of the short free-length spring to the outlet baffle and the feeding mechanism body respectively. After the initial assembly is completed, further adjust the installation position and tension of the spring. By adjusting the connection points between the spring and the baffle and the body, as well as the pre-compression of the spring itself, the front thrust of the thin bar stock during feeding can just push the outlet baffle, causing the baffle to perform a preset stroke action. The baffle action can accurately transmit signals to the Swiss Army machine control system, causing the control system to trigger the slow rotation command of the main shaft. When the bar stock enters the main shaft, the main shaft rotates at a slow speed to cooperate with the bar stock feeding, avoiding jamming or deformation of the thin bar stock due to excessive spindle speed, and ensuring that the bar stock can be smoothly fed into the subsequent fixture.

[0027] The feed end opening of the guide nylon sleeve 4 is a large-tapered conical surface inclined from the outer wall to the inner wall, with a taper angle of 45°-65°. By expanding the guiding range of the feed port, especially for thin bars such as φ4-φ6, the alignment accuracy requirements during feeding can be reduced. The front end of the bar does not need to be precisely aligned with the orifice and can slide naturally along the conical surface, reducing feeding jams or bar end collisions and deformations caused by alignment deviations. This ensures that the bar smoothly enters the guide nylon sleeve 4 and is guided smoothly into the main spindle clamp 2.

[0028] The workpiece of the Swiss-type lathe is equipped with a guide nylon sleeve 4 to ensure the installation accuracy of the guide sleeve and a tight fit between it and the machining components. When the tool holder assembly cuts slender shaft-type bar workpieces such as φ4-φ6, the guide sleeve can provide rigid support to the machining end of the workpiece, counteracting the radial bending moment generated by the cutting force, thereby reducing workpiece breakage or bending deformation caused by excessive force. At the same time, the guide nylon sleeve 4 provides a stable cutting reference for the tool by limiting the radial runout of the workpiece during machining, thereby improving the machining dimensional accuracy and surface finish, reducing rework caused by workpiece deformation, and indirectly improving machining efficiency.

[0029] The centering mechanism 3 includes a first cylinder 301, a centering frame 302, and anti-vibration wheels 304. The base of the first cylinder 301 is connected to the frame of the sliding headstock machine through a cylinder fixing plate. The telescopic rod of the first cylinder 301 passes through the cylinder fixing plate and is fixedly connected to the centering frame 302. The centering frame 302 is a heart-shaped support frame, and the bottom of the centering frame 302 is provided with an opening. Anti-vibration wheels 304 are symmetrically provided on the left and right bottoms of the centering frame 302. The two anti-vibration wheels 304 are located in the same horizontal plane, and the distance between them is less than the outer diameter of the material bar. By extending and retracting the first cylinder 301, the centering frame 302 is moved up and down, thereby adjusting the vertical height of the centering frame 302. Finally, the two anti-vibration wheels 304 are used to center, guide, and support material bars with different outer diameters passing through the middle of the centering frame 302.

[0030] The first cylinder 301 is a short-stroke secondary anti-vibration wheel cylinder. A horizontally positioned movable shaft 303 is located at the top center of the centering frame 302. The telescopic rod of the first cylinder 301 passes through the cylinder fixing plate and is fixedly connected to the movable shaft 303 at the top of the centering frame 302. The up-and-down extension and retraction of the first cylinder 301 drives the movable shaft 303 and the centering frame 302 to move up and down, ultimately controlling the centering and guiding of the two anti-vibration wheels 304 for bars of different outer diameters passing through the centering frame 302. The use of a short-stroke secondary anti-vibration wheel cylinder reduces the adjustable range of the cylinder, allowing the anti-vibration wheels to more closely contact the bar diameter, effectively reducing the swinging of the bar during spindle rotation and improving machining accuracy.

[0031] The short-stroke secondary anti-vibration wheel cylinder is fixed to the preset mounting holes on the cylinder fixing plate with bolts, ensuring that the axis of the cylinder output end is collinear with the axis of the movable shaft 303 in the middle of the centering frame 302; during the swinging process, the anti-vibration wheel 304 at the end of the heart-shaped support frame can accurately correspond to the bar stock conveying path. By adjusting the cylinder inlet pressure or the stroke limit component, the adjustable range of the cylinder's extension and retraction stroke is reduced, so that the anti-vibration wheel 304 can closely fit the outer wall of bars of different diameters under the drive of the first cylinder 301, avoiding gaps between the anti-vibration wheel 304 and the bar stock due to excessive stroke.

[0032] The push rod 6, anti-vibration bushing 7, centering mechanism 3, flow guide nylon sleeve 4, feeder clamp 5, and main shaft clamp are all located on the same axis as the feeder main shaft 1. This ensures that the bar stock runs stably along the main shaft axis throughout the entire process from feeding to processing, guaranteeing smooth conveying, reducing radial vibration offset, unifying the processing benchmark, and thus improving the processing accuracy of slender shaft workpieces.

[0033] An anti-vibration bushing 7 is fitted onto the push rod 6. The anti-vibration bushing 7 has a multi-segment composite structure, with multiple anti-vibration bushings 7 abutting at their ends and rotatably fitted onto the outside of the push rod 6. The interior of the anti-vibration bushing 7 is a channel that matches the outer diameter of the push rod 6, and the outer surface of the anti-vibration bushing 7 is a conical structure with a large outer diameter in the middle and gradually decreasing in size towards the left and right ends. The function of the anti-vibration bushing 7 is to effectively suppress the vibration of the push rod 6 during the process of the push rod 6 pushing the bar stock, thereby ensuring the stability of the bar stock conveying.

[0034] This utility model relates to a Swiss-type lathe for machining bar stock, and its specific working principle is as follows: First, the feeding stage is dominated by the feeding mechanism: the push rod 6, under the action of the anti-vibration bushing 7 of the outer sleeve, weakens the pushing vibration to stabilize the pushing of the bar stock; the bar stock first passes through the guide nylon sleeve 4, and is guided into the feeding port through the large-angle conical surface, and then the anti-vibration wheel 304 of the centering frame 302 is driven by the first cylinder 301 of the centering mechanism 3 to closely fit the outer wall of the bar stock to achieve centering and prevent the bar stock from swinging when the main shaft rotates; at the same time, the short free length spring of the outlet baffle of the feeding mechanism accurately triggers the signal when the thin bar stock is pushed, so that the main shaft rotates slowly and the bar stock enters the tooling assembly smoothly.

[0035] Entering the tooling clamping stage: The feeder clamp 5 adapts to and precisely guides bars of different diameters through a straight or stepped cylindrical section. The elastic telescopic body between the guide nylon sleeve 4 and the telescopic clamp 9 of the main shaft clamp 2 achieves flexible clamping, preventing deformation of thin bars. Furthermore, the push rod 6, anti-vibration bushing 7, centering mechanism 3, guide nylon sleeve 4, feeder clamp 5, and main shaft clamp 2 are all coaxial with the main shaft, ensuring stable transmission of bars along the main shaft axis and eliminating conveying deviation and clamping skew.

[0036] The machining stage combines tool holder assembly and process optimization: the cutting and grooving tool holder mounted on the left shortens the distance to the guide bushing, making the support point of the guide bushing on the workpiece and the cutting point of the tool closely matched, thus achieving uniform force on the tool holder; at the same time, the turning method is optimized through programming, reducing G01 linear interpolation turning and using G74 / G75 / G83 and other inching cycle chip breaking turning to avoid continuous cutting force accumulation, and adjusting the single turning amount according to the bar diameter and the material being machined to further reduce the turning force, reduce the risk of fracture and deformation when machining thin bars, and improve machining accuracy and surface quality.

[0037] Ultimately, through the coordinated structure of feeding, centering, clamping, and cutting, as well as the process optimization of turning methods and parameters, the processing range is expanded: the bar diameter range of the 20-type Swiss-type lathe is expanded from φ6-φ20 to φ4-φ20, and the bar diameter range of the 32-type Swiss-type lathe is expanded from φ8-φ32 to φ6-φ32. This not only meets the market demand for processing fine bars, but also ensures the stability, accuracy, and efficiency of processing bars of different specifications through the adaptation of structure and process.

[0038] In summary, this utility model of a Swiss-type lathe for processing bar stock features an ingenious structural design. By optimizing the elastic telescopic body of the spindle clamp, the feeder clamp combining stepped and straight cylindrical shapes, and the centering mechanism, it flexibly adapts to the clamping requirements of bars with different diameters, breaking through the original processing limitations. Simultaneously, the addition of a vibration-resistant bushing to the push rod, the use of a short-length feed outlet baffle spring, the increased taper of the guide nylon sleeve, and the adoption of a short-stroke secondary vibration-damping wheel cylinder reduce vibration and swaying during bar feeding and processing, preventing wear and tear on thinner bars and reducing guide resistance. Improvements to the tooling and tool holder assembly also result in more uniform processing force, reducing the risk of workpiece deformation and breakage, and improving processing accuracy. Moreover, the cost after the modification is far lower than purchasing new equipment, aligning with the concept of cost reduction and efficiency improvement, and enhancing market competitiveness.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
