[0002] In the field of mechanical processing, the lathe is a very important processing equipment, for a long time, the traditional lathe has many problems and limitations in tool adjustment and machining accuracy, efficiency and other aspects.

[0003] For the top structure, the traditional lathe top installation mode is rough, usually difficult to ensure that the top can rotate flexibly, can stably bear the larger axial and radial force. In the processing, the top is prone to wear, loose and other problems, affect the positioning accuracy of workpiece, and then lead to the accumulation of machining error, which is not conducive to the processing of high-precision parts.

[0004] In addition, the traditional lathe lacks effective real-time detection and error compensation mechanism. In the processing, due to the installation error of workpiece, the size error of top and other factors, the machining error is easy to produce, and the traditional lathe is difficult to accurately measure and compensate in time, which leads to high scrap rate, increases the production cost, and also reduces the overall processing efficiency of the equipment. The center positioning lathe positioned by the centering mode further reduces the precision under the accumulation of cumulative error when the top is replaced and worn.

[0005] Furthermore, the traditional lathe is difficult to realize accurate and stable control of the cutting angle and depth of the tool during processing, and uneven stress is easy to occur, which not only aggravates the wear of the tool and shortens the service life of the tool, but also causes great impact on the mechanical structure of the lathe, increases the failure rate of the equipment, and frequent maintenance further affects the continuity of production and the use efficiency of the equipment.

DETAILED DESCRIPTION

Obviously, the drawings in the following description only represent some embodiments of the utility model, and for those skilled in the art, other drawings can be obtained according to these drawings without creative labor, and other embodiments can also be obtained.

[0038] In order to make the drawing simple, only the parts related to the utility model are shown in each drawing, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the parts with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0039] In this paper, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrated connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0040] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0041] Referring to Figures 1-4 For the first embodiment of the utility model, a lathe convenient for adjusting tool is provided, which comprises a rack 1, the rack 1 is provided with a first center 101, a sliding rail 2 is arranged on the rack 1, a sliding part 3 is slidably arranged on the sliding rail 2, the sliding part 3 is provided with a second center 301, the second center 301 is coaxially arranged with the first center 101, a supporting plate 4 is movably arranged on the rack 1, the supporting plate 4 is provided with a mounting frame 401, a tool 5 is arranged on the mounting frame 401 and is used for machining a workpiece, and a position sensor 6 is arranged on one side of the tool 5 and is used for detecting the end face position of the workpiece to be machined.

[0042] In the embodiment, the rack 1 is integrally cast by high-strength cast iron, and the internal stress is eliminated through aging treatment to ensure the stability and precision of the structure. The bottom is equipped with heavy-duty shock-absorbing foot pads, which effectively isolate external vibrations and provide a stable foundation for precision machining. The first center 101 is installed at the bed head box part of the rack 1 and is connected with the rack 1 through a high-precision tapered roller bearing, which can rotate flexibly and can bear a large axial and radial force. The supporting plate 4 is made of aluminum alloy material, which reduces the overall weight while ensuring a certain rigidity. The moving mode adopts ball screw transmission, and the lead of the ball screw is selected according to the machining precision requirement. The mounting frame 401 is welded on the supporting plate 4, and the tool 5 can be flexibly installed on the mounting frame 401 through bolts, pressure plates and other ways according to different machining processes, meeting the requirements of drilling, turning, boring and other machining processes.

[0043] The position sensor 6 is installed on one side of the tool 5, and the sensor measures perpendicular to the end face of the workpiece. The sensor can accurately detect the end face position of the workpiece to be machined in real time. During the machining process, after the workpiece is installed between the two centers, the position sensor 6 first measures and transmits the end face position information of the workpiece to the numerical control system. According to the preset machining allowance, tool path and other parameters, the numerical control system automatically calculates the distance that the supporting plate 4 needs to move and the cutting depth of the tool 5, realizing automatic and precise machining control.

[0044] First, the workpiece to be machined is fixed through the first center 101 and the second center 301, and the lathe is started. The position sensor 6 automatically measures the end face position of the workpiece and transmits the data to the numerical control system. The numerical control system controls the supporting plate 4 to move to the initial position according to the programmed machining process, such as turning thread, cylindrical surface and hole, and adjusts the angle and position of the tool 5. The ball screw drives the supporting plate 4 to approach the workpiece at the predetermined cutting speed and feed rate, and the tool 5 starts to cut the workpiece.

[0045] This adjustment mode cleverly offsets the cumulative error caused by the size error of the first tip 101 and the second tip 301 through the cooperation of the position sensor 6 and the pallet 4. Before processing, the position sensor 6 driven by the pallet 4 approaches the workpiece to accurately capture the position of the workpiece end face, which sets an accurate "starting point" for subsequent processing. Based on this positioning information, the pallet 4 moves accurately again to escort the cutter 5 to the ideal processing position, ensuring the high-precision matching of the relative position of the cutter 5 and the workpiece, greatly improving the processing precision, especially in the field of precision component manufacturing, effectively reducing the scrap rate, and ensuring the consistency and reliability of product quality.

[0046] The cutter 5 adjustment process is highly automated and efficient. Regardless of the initial installation state of the workpiece, the adjustment system composed of the position sensor 6 and the pallet 4 can quickly adapt and dynamically adjust the position of the cutter 5. Compared with traditional manual adjustment of the cutter, a lot of debugging time is saved, the processing efficiency of the lathe is significantly improved, the demand for high rhythm and multi-variety processing of modern production lines is met, the equipment can quickly switch tasks, and the processing challenges of different specifications of workpieces can be flexibly responded. Through accurate positioning and error compensation, the uneven force condition of the cutter 5 during processing is reduced. Stable cutter cutting angle and depth reduce vibration and impact during cutting, not only protecting the cutter 5 and prolonging its service life, but also reducing wear and tear on the overall mechanical structure of the lathe, maintaining the high-precision operating state of the equipment, reducing equipment failure rate, reducing maintenance cost, and providing strong support for long-term stable production.

[0047] Further, it further comprises a clamping piece 7, which is slidingly arranged on the pallet 4 and located on one side of the cutter 5, used for fixing the position sensor 6.

[0048] In this embodiment, the clamping piece 7 provides a reliable and accurate fixing method for the position sensor 6. It can firmly lock the position sensor 6 in the ideal position on the pallet 4, ensuring that the position sensor 6 does not loosen, displace or shake during the high-speed operation of the lathe and the frequent movement of the pallet 4. This stability is crucial for the sensor to accurately obtain the position information of the workpiece end face. Once the sensor position deviates, the measurement data will be inaccurate, affecting the precision control of the entire processing process. The stable action of the clamping piece 7 effectively avoids such problems and ensures the continuation of high-precision processing. The clamping piece 7 has a sliding function, which allows the installation position of the position sensor 6 to be adjusted flexibly according to different processing needs and workpiece specifications. When facing diversified processing tasks, such as processing workpieces of different diameters and lengths, the operator can conveniently change the orientation of the position sensor 6 relative to the cutter 5 and the workpiece by sliding the clamping piece 7, ensuring that the sensor is always in the best measurement angle and accurately captures the dynamic position of the workpiece end face. This flexibility greatly expands the application range of the lathe, enabling it to handle more complex and variable processing scenarios without the need for frequent sensor replacement or recalibration.

[0049] Further, the supporting plate 4 has a sliding groove 402, and the clamping piece 7 has a sliding part 701 which is slidingly arranged in the sliding groove 402.

[0050] In the embodiment, the cooperation between the sliding part 701 and the sliding groove 402 provides the clamping piece 7 with accurate movement guidance. When adjusting the position sensor 6, the clamping piece 7 can only linearly slide along the predetermined direction of the sliding groove 402, avoiding the misalignment of the sensor position caused by random shaking or deviation. This high-precision guidance ensures that the position sensor 6 can accurately align with the workpiece end face after each adjustment, providing a reliable basis for the subsequent accurate adjustment of the tool 5, effectively improving the overall machining precision of the lathe.

[0051] The sliding groove 402 serves as a structure for bearing the sliding part 701, providing the clamping piece 7 with a stable support platform. Even during the long-term and high-intensity work of the lathe, in the face of frequent movement, start-stop of the supporting plate 4, and vibration impact during the machining process, the sliding part 701 can still maintain stability in the sliding groove 402 and will not appear abnormal conditions such as derailment and jamming. This makes the position sensor 6 fixed by the clamping piece 7 always in a stable working state, continuously outputs accurate workpiece end face position information, ensures the smooth progress of the machining process, reduces the downtime caused by equipment failure, and improves production efficiency.

[0052] The operator can simply push the clamping piece 7 to quickly and conveniently adjust the position of the position sensor 6 by using the sliding characteristics of the sliding part 701 in the sliding groove 402. Compared with complex adjustment mechanisms, this sliding design is intuitive and easy to use without the need for professional tools or complex training. When facing different sizes and shapes of workpieces that need to be frequently replaced for machining processes, the operator can quickly complete the adaptive adjustment of the position sensor 6, thereby speeding up the adjustment speed of the tool 5, shortening the machining cycle of single workpiece, especially suitable for small batch and multi-variety production mode, improving the flexible machining capability of the lathe.

[0053] Further, the clamping piece 7 is rotationally and slidingly arranged in the sliding groove 402, the sliding part 701 has a first clamping part 702, the sliding groove 402 has a plurality of second clamping parts 403 arranged in sequence, and the first clamping part 702 is clamped or unclamped with the second clamping part 403 after the clamping piece 7 is rotated.

[0054] In this embodiment, the clamping piece 7 is rotatably and slidably arranged in the sliding groove 402, greatly expanding the adjustment dimension of the position sensor 6. In the face of diversified processing tasks, this multifunctional arrangement enables the position of the position sensor 6 to be quickly reconfigured. In a production line that frequently switches between processing different types of workpieces, the operator only needs to simply rotate and slide the clamping piece 7 to quickly match the position sensor 6 with the end face position measurement requirements of the new workpiece, and then quickly complete the adjustment of the tool 5, reducing the time spent on equipment debugging due to the change of processing objects, significantly improving the machining efficiency and flexible production capacity of the lathe, and is suitable for rapid production switching requirements in the multi-variety small-batch production mode in the mechanical manufacturing industry.

[0055] When the clamping piece 7 moves to the appropriate position, the first clamping part 702 is clamped with the second clamping part 403, which can firmly lock the height position of the clamping piece 7, effectively preventing the clamping piece 7 from being accidentally raised or lowered due to factors such as vibration and cutting force during the operation of the lathe, and ensuring that the position sensor 6 is always stably positioned at the set optimal measurement position. Compared with the method of simply relying on friction or ordinary limiting structure for fixation, this clamping mechanism provides more reliable fixation effect, ensuring the accuracy and continuity of the workpiece end face position information collected by the position sensor 6, and providing strong guarantee for the precise adjustment of the tool 5 and stable processing, especially in high-precision processing occasions, which can minimize the processing errors caused by changes in the position of the sensor.

[0056] When the position or angle of the position sensor 6 needs to be adjusted again, the first clamping part 702 and the second clamping part 403 can be easily uncoupled, allowing the operator to easily rotate or slide the clamping piece 7, and the operation process is simple and fast, without the need for complex disassembly or unlocking steps, further demonstrating the good balance between the design in convenient adjustment and stable positioning, optimizing the convenience and efficiency of the entire tool adjustment process.

[0057] Further, the clamping piece 7 has a first guide surface 703 and a second guide surface 704, the first guide surface 703 and the second guide surface 704 are respectively arranged on both sides of the first clamping part 702, and the clamping piece 7 further has a locking piece 8, the locking piece 8 is arranged in the sliding groove 402, the locking piece 8 has a first clamping part 801 and a second clamping part 802, the first clamping part 801 and the second clamping part 802 are respectively in abutment with the first guide surface 703 and the second guide surface 704, and the locking piece 8 is configured to be movably arranged relative to the sliding groove 402 and fixedly arranged relative to the clamping piece 7.

[0058] In this embodiment, the setting of the anti-loosening piece 8 further stabilizes the clamping state of the clamping piece 7. The first clamping part 801 and the second clamping part 802 respectively abut against the first guide surface 703 and the second guide surface 704, forming a multi-directional constraint structure. During the operation of the lathe, no matter whether it is subjected to cutting force, vibration or other external force interference, the anti-loosening piece 8 can effectively prevent loosening or accidental unclamping between the first clamping part 702 and the second clamping part 403, ensuring that the clamping piece 7 is firmly fixed at the set position, and the position sensor 6 can continuously and stably be at the optimal measurement position, providing accurate workpiece end surface position information for tool 5 adjustment, minimizing processing errors caused by sensor position changes, ensuring processing accuracy, and being particularly suitable for high-precision and ultra-precision part processing scenarios.

[0059] During long-term processing and use, the continuous vibration of the equipment and the repeated stress of the parts can cause slight loosening of the clamping structure, which in turn affects the overall processing accuracy. The anti-loosening piece 8, through close abutment with the guide surface, can maintain the tightness of the clamping for a long time, ensuring that the accuracy reference for tool 5 adjustment remains stable throughout the processing process, ensuring that each processed workpiece meets high and stable quality standards, reducing the problem of reduced processing accuracy caused by long-term operation of the equipment, and prolonging the effective use period of the equipment under high-precision processing requirements.

[0060] The first guide surface 703 and the second guide surface 704 not only play a role in being abutted and fixed, but also guide the clamping operation of the clamping piece 7. After the operator rotates the clamping piece 7 to make the first clamping part 702 and the second clamping part 403 clamped, the guide surface can guide the first clamping part 801 and the second clamping part 802 of the anti-loosening piece 8 to accurately align and tightly abut, ensuring that each clamping operation is accurately completed, avoiding the occurrence of clamping out of position due to manual operation errors. This precise structural cooperation improves the assembly efficiency and positioning accuracy of the equipment in daily use, reduces the hidden troubles caused by poor assembly, and enhances the overall reliability of the equipment.

[0061] When the lathe is working, external forces are transmitted to the clamping part of the clamping piece 7 through various channels, and the abutment structure of the anti-loosening piece 8 and the guide surface can reasonably disperse these forces. The force originally concentrated on the clamping part is conducted to the anti-loosening piece 8 through the guide surface and then evenly dispersed to the surrounding structure, avoiding the situation that the local force is too large, causing damage or deformation of the clamping part, the sliding groove 402 and other related parts, protecting the key structures of the equipment, reducing the probability of damage of the parts due to uneven stress, reducing the maintenance frequency of the equipment, improving the service life of the equipment, and reducing the maintenance cost of the equipment during long-term operation.

[0062] Further, the clamping piece 7 penetrates the anti-loosening piece 8, the first clamping part 801 and the second clamping part 802 both have a threaded part 803, and further comprising a positioning nut 9 and an abutting nut 10, the positioning nut 9 and the abutting nut 10 are respectively threaded on the threaded part 803, and are located at both ends of the anti-loosening piece 8, and are respectively located on both sides of the supporting plate 4, for fixing the anti-loosening piece 8 and the supporting plate 4.

[0063] In this embodiment, the clamping piece 7 penetrates the anti-loosening piece 8, and the anti-loosening piece 8 is tightly fixed on the supporting plate 4 by cooperating with the positioning nut 9 and the abutting nut 10, thereby constructing an extremely stable structure system. When the lathe is used for high-precision machining, no matter how severe the cutting vibration and complex stress change are, the clamping piece 7 can remain unchanged, and the position sensor 6 can always be kept at the precise measurement point, so as to ensure that the tool 5 can adjust the height of the workpiece end surface accurately. This stability is very important for the field of ultra-precision machining such as high-end optical lens mold and precision electronic component manufacturing, and can control the machining error within a very small range, thereby greatly improving the product quality and the qualified rate.

[0064] During the long-time and high-intensity machining operation, the clamping and fixing structure of the traditional lathe is prone to loosen due to fatigue and wear, which causes the machining precision to decline. However, the design of the anti-loosening piece 8 can effectively resist the test of time and working conditions, and can maintain the precise cooperation between the components for a long time. Even after thousands of hours of continuous operation, the stability of the tool 5 can still be ensured, and the problem of increasing the waste rate caused by equipment aging can be reduced, thereby prolonging the service life of the equipment under the requirement of precision.

[0065] During the equipment assembly process, the design of the positioning nut 9 and the abutting nut 10 greatly simplifies the fixing process of the anti-loosening piece 8 and the supporting plate 4. The operator only needs to put the anti-loosening piece 8 into the clamping piece 7 and place it at the corresponding position of the supporting plate 4, and then tighten the nuts at both ends to quickly complete the installation. The operation is simple and fast. At the same time, the thread cooperation during the nut tightening process can automatically adjust the position of the anti-loosening piece 8, so that it is accurately aligned with the clamping piece 7 and the supporting plate 4, thereby effectively avoiding the equipment failure caused by improper assembly, and improving the quality and efficiency of the initial assembly of the equipment.

[0066] When the lathe encounters sudden overload impact, external force collision and other abnormal working conditions, the firm nut fixing structure can provide strong support and protection for the anti-loosening piece 8. The threaded part 803 and the nut are tightly engaged, and the external force is evenly dispersed to the supporting plate 4 and the surrounding structure, so as to prevent the anti-loosening piece 8 from being displaced, deformed or damaged, thereby ensuring the safety and stability of the clamping piece 7 and the position sensor 6, reducing the risk of equipment damage caused by accidents, and enhancing the reliability of the whole equipment in dealing with complex working conditions.

[0067] Further, the diameter of the threaded part 803 of the anti-loosening piece 8 is greater than the width of the sliding part 701.

[0068] In this embodiment, the threaded portion 803 of the anti-loosening piece 8 has a larger diameter than the sliding portion 701, so that the anti-loosening piece 8 occupies a larger space in the sliding groove 402 and has a relatively larger contact area with the inner wall of the sliding groove 402. When the lathe is running, especially when it is subjected to cutting force impact, equipment vibration, etc., the larger contact area means that external forces can be better dispersed, so that the anti-loosening piece 8 is more stable in the predetermined position, thereby ensuring that the clamping piece 7 cooperating with it is also stable and does not move. In this way, the position sensor 6 can continuously and stably function to provide reliable workpiece end face position information for accurate adjustment of the tool 5, which helps to improve the machining precision, especially for precision parts machining scenes with high precision requirements.

[0069] Compared with the case where the diameter of the anti-loosening piece 8 is smaller, the larger diameter makes the structure of the anti-loosening piece 8 more rigid. When subjected to external forces, it is not easy to deform or relatively shake or displace. This avoids unnecessary interference from the anti-loosening piece 8 to the clamping piece 7 due to instability, ensures that the clamping piece 7 can always maintain accurate position and angle after rotation, clamping and other operations, reduces the accumulation of position deviation caused by relative movement between components, and ensures the accuracy of tool 5 adjustment and the stability of the entire machining process.

[0070] Because the diameter of the anti-loosening piece 8 is larger, when external forces act on the clamping piece 7 and are transmitted to the anti-loosening piece 8, it can evenly disperse these forces to the surrounding structures, such as the inner wall of the sliding groove 402 and the supporting plate 4 associated with it, like a stable “force hub”. This balanced force distribution can effectively prevent local overloading and damage to components, prolong the service life of related components, reduce the probability of equipment failure due to frequent uneven forces, ensure the long-term stable operation of the lathe, reduce maintenance costs and downtime, and is very beneficial for production scenes that require long-time continuous operation, such as lathe machining links in automated production lines.

[0071] Further, the first clamping portion 801 and the second clamping portion 802 each have an abutting surface 804 abutting with the side wall of the sliding groove 402.

[0072] In this embodiment, the abutting surfaces 804 of the first clamping portion 801 and the second clamping portion 802 abut with the side wall of the sliding groove 402, so that the anti-loosening piece 8 is effectively limited and constrained in the transverse direction. During the operation of the lathe, whether it is vibration caused by cutting or other external force interference, the anti-loosening piece 8 is difficult to displace or shake in the transverse direction, thereby ensuring that the clamping piece 7 connected thereto can be stably positioned at the set position, so that the position sensor 6 can continuously and accurately monitor the workpiece end face position to provide a reliable basis for the adjustment of the tool 5, effectively improving the machining precision.

[0073] By the close abutment of the abutment surface 804 and the side wall of the sliding groove 402, the anti-loosening piece 8 becomes a "stable framework" in the entire structure, enhancing the rigidity of the entire tool adjustment related structure in the transverse plane. This not only reduces wear between components due to relative movement, prolonging the service life of each component, but also avoids the accumulation of position deviation caused by loose structure, ensuring that the accuracy of tool 5 adjustment remains at a high level during long-term processing, maintaining stable and reliable operation of the equipment, reducing downtime and maintenance costs caused by equipment failure.

[0074] When external forces act on the clamping piece 7 and the anti-loosening piece 8, the abutment surface 804 effectively transmits these external forces to the side wall of the sliding groove 402, and then further disperses through the surrounding structure such as the supporting plate 4 where the sliding groove 402 is located. This force transmission and dispersion mechanism avoids the occurrence of excessive local stress, enabling the entire structural system to better withstand the complex external forces during cutting processing, protecting the key components from damage caused by uneven stress, such as preventing the sliding groove 402, clamping piece 7 and other components from deforming, breaking and other problems caused by local stress concentration, ensuring the structural integrity and long-term stability of the equipment.

[0075] In the tool adjustment system, some connection parts are relatively weak and prone to damage due to external force impact. The abutment design of the abutment surface 804 and the side wall of the sliding groove 402 can share the external forces borne by these connection parts, reducing their stress burden, such as reducing the stress at the connection points of the clamping piece 7 and other components, reducing the risk of connection loosening and damage, ensuring the connection reliability between the components of the entire tool adjustment system, enabling the system to work stably and continuously to perform its function of precisely adjusting the tool 5.

[0076] Further, the anti-loosening piece 8 has a connecting part 805 for connecting the first clamping part 801 and the second clamping part 802.

[0077] In this embodiment, the connecting part 805 connects the first clamping part 801 and the second clamping part 802, making the anti-loosening piece 8 form an organic whole structure. During the operation of the lathe, in the face of cutting force, vibration and other external force interference, this integrated design can avoid relative displacement or deformation of the first clamping part 801 and the second clamping part 802, thereby ensuring the stable function of the entire anti-loosening piece 8. It can firmly fix the clamping piece 7, ensure that the position sensor 6 is always in a precise measurement position, provide reliable workpiece end face position information for tool 5 adjustment, and effectively improve the machining precision.

[0078] After a long time of use, the components of the device may face problems such as fatigue and looseness due to frequent stress. The presence of the connecting part 805 enhances the structural strength of the anti-loosening part 8, enabling it to maintain a stable state for a long time and reducing structural changes due to increased use time. This helps to maintain the accuracy of the cutter 5 adjustment, ensuring that the machining precision remains stable at a high level throughout the service life of the device, reducing machining errors caused by device aging, prolonging the effective service life of the device, and reducing the cost of equipment updating and maintenance for enterprises.

[0079] Further, the position sensor 6 is an infrared sensor.

[0080] In this embodiment, the infrared sensor is a non-contact sensor, which does not need to be in direct contact with the surface of the workpiece when detecting the end face position of the workpiece to be machined, avoiding the problem of scratching the surface of the workpiece and the wear of the sensor itself caused by contact. At the same time, it can perceive the position change of the end face of the workpiece with very high precision, usually with a resolution of millimeters or even microns, providing a very reliable data basis for the precise adjustment of the cutter 5 and effectively improving the machining precision.
