Description

Technical Field

[0001] This application relates to the field of machine tools or machine tool components, and in particular to a tailstock center adjustment device, a tailstock assembly, and an adjustment method. Background Technology

[0002] In the field of machining, lathes, milling machines, and other machine tools have extensive needs for machining long-shaft workpieces (such as optical shafts, lead screws, and stepped shafts). The tailstock center, as a core auxiliary component, directly determines the workpiece machining quality (such as coaxiality and cylindricity) and production efficiency through its performance and adjustment accuracy. Currently, in the industry, the tailstock center mainly forms a "two-point support" by cooperating with the spindle center (or chuck) to solve the machining deformation problem caused by insufficient rigidity of long-shaft workpieces. It also undertakes key functions such as ensuring end face perpendicularity and assisting in clamping and positioning. Especially in high-speed machining scenarios, the "live center," with its internal rolling bearing structure, can avoid frictional loss and workpiece overheating, becoming an important support for high-precision machining.

[0003] However, traditional tailstock center adjustment methods have significant technical drawbacks, failing to meet the dual demands of efficiency and precision in modern machining. On one hand, the core objective of adjustment is to achieve "strict coaxiality between the center axis and the spindle axis" (including radial and axial alignment). However, traditional adjustments rely on manual operation, requiring repeated calibration with tools such as dial indicators and micrometers. This process is cumbersome and time-consuming, especially demanding high operator skills. Novices are prone to causing defects such as taper and coaxiality deviations in the workpiece due to operational errors. On the other hand, traditional adjustment structures lack efficient radial adjustment mechanisms. Adjustments require gradual fine-tuning and multiple checks, failing to quickly respond to the dynamic correction needs of the center position during machining. Furthermore, the lack of a stable locking structure after adjustment makes the center position prone to shift due to machine tool vibration, further affecting machining stability. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This part of the invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] Therefore, a first aspect of the present invention provides a tailstock tip adjustment device.

[0007] A second aspect of the present invention provides a tailstock assembly.

[0008] A third aspect of the present invention provides a method for adjusting the tailstock tip.

[0009] In view of the above, a tailstock tip adjustment device is provided according to a first aspect of the embodiments of this application. The tailstock tip includes a sleeve and a movable tip, the movable tip being disposed within the sleeve. The tailstock tip adjustment device includes: A housing for connection to the sleeve; An eccentric shaft, part of which is rotatably disposed within the housing, with both ends of the eccentric shaft extending through the housing, one end of the eccentric shaft being an adjustment end and the other end being an actuation end; An adjusting component is provided, wherein the sleeve has a groove, the adjusting component is disposed in the groove, and the adjusting component is connected to the actuating end for contacting the moving tip.

[0010] In one feasible implementation, the housing includes: A guide sleeve, in which part of the eccentric shaft is disposed; An eccentric cover is connected to the guide sleeve, the adjusting end extends through the guide sleeve, and the actuating end extends through the guide sleeve.

[0011] In one feasible implementation, the tailstock tip adjustment device further includes: An assembly nut is fitted onto the eccentric shaft and connected to the eccentric cover; A first elastic element is disposed between the mounting nut and the guide sleeve.

[0012] In one feasible implementation, the tailstock tip adjustment device further includes: A dial, connected to the eccentric cover, is marked with the degree of eccentricity.

[0013] In one feasible implementation, the adjusting member includes: An adjusting key and a joint bearing, wherein the adjusting key is connected to the actuating end via the joint bearing.

[0014] In one feasible implementation, the tailstock tip adjustment device is arranged along the radial direction of the tailstock tip, and the adjustment member is arranged along the axial direction of the tailstock tip.

[0015] In one feasible embodiment, the tailstock center adjustment device further includes: a locking assembly for locking the eccentric shaft to prevent rotation of the eccentric shaft; the locking assembly includes: A locking screw, which is connected to the sleeve; A locking block abuts against the locking screw, and the locking block is used to abut against the eccentric shaft.

[0016] In one feasible implementation, the tailstock tip adjustment device further includes: An adjusting nut is provided at the adjusting end of the eccentric shaft.

[0017] A tailstock assembly is provided according to a second aspect of the embodiments of this application, comprising: Tailstock tip adjustment device as described in any of the above technical solutions; Tailstock tip, and the tailstock tip adjustment device is connected to the tailstock tip.

[0018] According to a third aspect of the embodiments of this application, a method for adjusting the tailstock tip is provided for application to the tailstock assembly as described in any of the above technical solutions, the adjustment method comprising: The moving tip is driven to move along the length of the sleeve to achieve position adjustment of the moving tip in a first direction; Rotate the adjusting end of the tailstock tip adjusting device so that the eccentric shaft drives the adjusting member to move, and the adjusting member contacts the moving tip to realize the position adjustment of the moving tip in the second direction.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects: The tailstock center adjustment device provided in this embodiment includes a housing, an eccentric shaft, and an adjusting component. When the position of the moving center needs to be adjusted, the operator can rotate the adjusting end of the eccentric shaft. Since part of the eccentric shaft is rotatably mounted inside the housing, rotating the adjusting end will cause the entire eccentric shaft to rotate within the housing, thereby causing the actuator end of the eccentric shaft to move synchronously. Because the adjusting component is connected to the actuator end and is located within a groove in the sleeve, the movement of the actuator end will drive the adjusting component to move within the groove. As the adjusting component moves, it contacts the moving center within the sleeve. Under the eccentric action of the eccentric shaft, the force exerted by the adjusting component on the moving center achieves the adjustment of the moving center's position. Throughout the process, the housing remains connected to the sleeve, providing stable support for the eccentric shaft and the adjusting component.

[0020] The tailstock center adjustment device provided in this application embodiment achieves effective adjustment of the moving center through the cooperation of the housing, eccentric shaft, and adjusting component. The housing connecting sleeve or tailstock assembly ensures the overall installation stability of the device and prevents structural loosening during adjustment. The rotational design of the eccentric shaft converts the operator's adjustment action into the movement of the actuator. The adjusting component can be driven simply by rotating the adjusting end, making operation convenient and eliminating the need for complex manual operations. The adjusting component moves within the sleeve groove and contacts the moving center, accurately acting on the moving center and ensuring the accuracy of position adjustment. At the same time, the groove's limiting effect on the adjusting component prevents it from shifting, further improving adjustment accuracy and ensuring the stability and precision of subsequent workpiece processing.

[0021] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

Detailed Implementation

[0024] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0026] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0027] like Figures 1 to 11 As shown, a tailstock tip adjustment device is provided according to a first aspect of the embodiments of this application. The tailstock tip includes a sleeve 210 and a movable tip 220. The movable tip 220 is disposed within the sleeve 210. The tailstock tip adjustment device includes: a housing 110 for connection to the sleeve 210; an eccentric shaft 120, a portion of which is rotatably disposed within the housing 110, with both ends of the eccentric shaft 120 extending through the housing 110, one end of which is an adjustment end 121 and the other end is an actuation end 122; and an adjustment member 130, in which the sleeve 210 has a groove 230, the adjustment member 130 is disposed within the groove 230, and the adjustment member 130 is connected to the actuation end 122 for contacting the movable tip 220.

[0028] The tailstock tip adjustment device provided in this embodiment includes a housing 110, an eccentric shaft 120, and an adjusting member 130. When the position of the moving tip 220 needs to be adjusted, the operator can turn the adjusting end 121 of the eccentric shaft 120. Since part of the eccentric shaft 120 is rotatably disposed within the housing 110, turning the adjusting end 121 will cause the entire eccentric shaft 120 to rotate within the housing 110, thereby causing the actuating end 122 of the eccentric shaft 120 to move synchronously. Since the adjusting member 130 is connected to the actuating end 122 and is disposed within the groove 230 of the sleeve 210, the movement of the actuating end 122 will drive the adjusting member 130 to move within the groove 230. As the adjusting member 130 moves, it contacts the moving tip 220 within the sleeve 210. Under the eccentric action of the eccentric shaft 120, the position of the moving tip 220 is adjusted through the force exerted by the adjusting member 130 on the moving tip 220. Throughout the process, the housing 110 remains connected to the sleeve 210, providing stable support for the eccentric shaft 120 and the adjusting component 130.

[0029] The tailstock center adjustment device provided in this embodiment achieves effective adjustment of the moving center 220 through the cooperation of the housing 110, the eccentric shaft 120, and the adjusting component 130. The housing 110 connects to the sleeve 210 or the tailstock assembly, ensuring the overall installation stability of the device and preventing structural loosening during adjustment. The rotational design of the eccentric shaft 120 converts the operator's adjustment action into the movement of the actuator 122. The adjusting component 130 can be driven simply by rotating the adjusting end 121, making operation convenient and eliminating the need for complex manual operations. The adjusting component 130 moves within the groove 230 of the sleeve 210 and contacts the moving center 220, precisely acting on the moving center 220 to ensure accurate position adjustment. Simultaneously, the groove 230 limits the adjusting component 130, preventing it from shifting and further improving adjustment accuracy, thus ensuring the stability and precision of subsequent workpiece processing.

[0030] like Figures 1 to 11 As shown, in one feasible embodiment, the housing 110 includes: a guide sleeve 111, a portion of the eccentric shaft 120 disposed within the guide sleeve 111; an eccentric cover 112 connected to the guide sleeve 111, an adjusting end 121 extending through the guide sleeve 111, and an actuating end 122 extending through the guide sleeve 111.

[0031] In this technical solution, the structural composition of the housing 110 is further provided. The housing 110 may include a guide sleeve 111 and an eccentric cover 112. During adjustment, the operator acts on the adjusting end 121 of the eccentric shaft 120. Since part of the eccentric shaft 120 is located inside the guide sleeve 111, rotating the adjusting end 121 will drive the eccentric shaft 120 to rotate stably within the guide sleeve 111, and the actuator 122 will move synchronously accordingly. The eccentric cover 112 is connected to the guide sleeve 111, providing protection and support for the guide sleeve 111 and the internal eccentric shaft 120 to avoid external interference. The adjusting end 121 and the actuator 122 extend through the eccentric cover 112 and the guide sleeve 111, respectively, ensuring that the adjustment operation can be carried out smoothly and that the movement can be accurately transmitted to the actuator 122, thereby driving the adjusting component 130 to move and realize the position adjustment of the moving tip 220. The entire structural movement is stable and controllable. The guide sleeve 111 provides installation and rotation space for the eccentric shaft 120, ensuring the coaxiality and stability of the eccentric shaft 120 during rotation and preventing the eccentric shaft 120 from shifting and affecting the adjustment accuracy. The eccentric cover 112 cooperates with the guide sleeve 111 to form a protective structure, which can prevent dust and impurities from entering, protect the internal components such as the eccentric shaft 120, and extend the service life of the device. At the same time, the design of the adjusting end 121 and the actuating end 122 extending through the guide sleeve 111 not only facilitates the operator's force adjustment but also ensures accurate motion transmission, improving the convenience and reliability of the adjustment operation and laying the foundation for the accuracy of the position adjustment of the moving center 220.

[0032] like Figures 1 to 6 As shown, in one feasible embodiment, the tailstock tip adjustment device further includes: an assembly nut 113, which is sleeved on the eccentric shaft 120 and connected to the eccentric cover 112; and a first elastic element 114, which is disposed between the assembly nut 113 and the guide sleeve 111.

[0033] In this technical solution, the tailstock tip adjustment device may further include an assembly nut 113 and a first elastic element 114. The assembly nut 113 is fitted onto the eccentric shaft 120 and connected to the eccentric cover 112, providing initial positioning for the eccentric shaft 120. The first elastic element 114 is positioned between the assembly nut 113 and the guide sleeve 111, generating an elastic force. During adjustment, the eccentric shaft 120 rotates, and the first elastic element 114 adapts to the positional change of the assembly nut 113 through elastic deformation. After adjustment, the elastic force reverses and tightens the assembly nut 113, which, in conjunction with its connection to the eccentric cover 112, restricts the autonomous rotation of the eccentric shaft 120, ensuring structural stability. The connection between the assembly nut 113 and the eccentric cover 112 strengthens the overall structural coherence of the device, prevents the eccentric shaft 120 from loosening or shifting, and improves structural stability during adjustment. The first elastic element 114, through continuous elastic tightening, effectively prevents the assembly nut 113 from rotating, thereby avoiding the eccentric shaft 120 from rotating on its own due to vibration, ensuring the accuracy of the adjusted position and reducing the frequency of readjustment. At the same time, the elastic element can buffer the impact between the assembly nut 113 and the guide sleeve 111 during the adjustment process, reducing component wear, extending the service life of the device, and improving the overall operational reliability.

[0034] like Figures 6 to 11 As shown, in one feasible embodiment, the tailstock center adjustment device further includes a dial 140 connected to the eccentric cover 112, with eccentricity marked on the dial 140. The dial 140, connected to the eccentric cover 112, provides a direct reference for adjustment operations. During adjustment, the operator can precisely control the rotation amplitude of the eccentric shaft 120 by observing the scale on the dial 140, eliminating the need for repeated trial adjustments based on experience, and quickly adjusting the eccentric shaft 120 to the target eccentricity, significantly improving adjustment efficiency. Simultaneously, the clear eccentricity markings avoid human error, ensuring consistency and accuracy in each adjustment, reducing the problem of inaccurate positioning of the moving center 220 due to eccentricity deviations, providing stable assurance for subsequent workpiece machining accuracy, and is particularly suitable for machining scenarios with high adjustment accuracy requirements, lowering the operational threshold and improving the applicability of the device.

[0035] In one feasible embodiment, the adjusting component 130 includes an adjusting key 131 and a spherical bearing 132, with the adjusting key 131 connected to the actuating end 122 via the spherical bearing 132. This configuration, where the adjusting key 131 is connected to the actuating end 122 via the spherical bearing 132, significantly improves the flexibility and adaptability of the adjustment. The spherical bearing 132 can rotate at multiple angles, adapting to the force direction of the adjusting key 131 when the eccentric shaft 120 drives the actuating end 122, preventing jamming between the adjusting key 131 and the groove 230 of the sleeve 210, ensuring smooth adjustment. Simultaneously, the spherical bearing 132 buffers the impact force between the adjusting key 131 and the actuating end 122, reducing component wear and extending service life. Furthermore, this connection method ensures that the adjusting key 131 always fits tightly against the moving tip 220, making force transmission more precise and preventing a decrease in adjustment accuracy due to connection deviations, providing a reliable guarantee for the stability and accuracy of the moving tip 220's position adjustment.

[0036] like Figures 1 to 11 As shown, in one feasible embodiment, the tailstock tip adjustment device is arranged radially along the tailstock tip, and the adjustment component 130 is arranged axially along the tailstock tip. This arrangement, with the tailstock tip adjustment device arranged radially and the adjustment component 130 arranged axially, optimizes the force transmission path and space utilization. The radial arrangement allows the device to directly act on the radial position adjustment of the moving tip 220, reducing force loss and improving adjustment response speed. The axially arranged adjustment component 130 has better compatibility with the sleeve 210 and groove 230, allowing for stable contact with the moving tip 220, ensuring uniform force transmission and preventing excessive local stress that could damage components. Simultaneously, this arrangement makes the device structure more compact, saves internal tailstock space, adapts to different tailstock assemblies, and facilitates subsequent maintenance and repair, further improving the device's practicality and adaptability, and ensuring the accuracy and stability of the moving tip 220 adjustment.

[0037] like Figures 1 to 11 As shown, in one feasible embodiment, the tailstock tip adjustment device further includes: a locking assembly 150, which is used to lock the eccentric shaft 120 to prevent the eccentric shaft 120 from rotating; the locking assembly 150 includes: a locking screw 151, which is connected to the sleeve 210; and a locking block 152, which abuts against the locking screw 151 and is used to abut against the eccentric shaft 120.

[0038] In this technical solution, the tailstock tip adjustment device may further include a locking assembly 150, which may include a locking screw 151 and a locking block 152. After the position adjustment of the moving tip 220 is completed, when it is necessary to lock the eccentric shaft 120, the operator can tighten the locking screw 151 connected to the sleeve 210. As the locking screw 151 is screwed in, it applies pressure to the abutting locking block 152. The locking block 152 abuts tightly against the surface of the eccentric shaft 120. Through the friction between the locking block 152 and the eccentric shaft 120, the rotational freedom of the eccentric shaft 120 is restricted, thereby locking the eccentric shaft 120. If readjustment is required, the locking screw 151 is loosened in the opposite direction, the pressure of the locking block 152 is released, the locking of the eccentric shaft 120 is released, and the adjustment function is restored. The locking assembly 150, through the cooperation of the locking screw 151 and the locking block 152, reliably locks the eccentric shaft 120, preventing it from rotating independently after adjustment due to machine tool vibration or machining stress. This ensures the stability of the moving center 220 and prevents machining accuracy deviations. The design of the locking screw 151 connecting to the sleeve 210 ensures stable transmission of locking force; the locking block 152, through deformation, abuts against the eccentric shaft 120, providing a high degree of fit and strong locking effect without causing rigid damage to the eccentric shaft 120. Furthermore, locking and unlocking operations only require turning the screw, which is convenient and efficient, requiring no complex tools and improving the ease of use of the device and the reliability of the machining process.

[0039] like Figures 1 to 11 As shown, in one feasible embodiment, the tailstock tip adjustment device further includes an adjustment nut 160, which is disposed at the adjustment end 121 of the eccentric shaft 120.

[0040] In this technical solution, the tailstock tip adjustment device also includes an adjusting nut 160, which is located at the adjusting end 121 of the eccentric shaft 120. This provides the operator with a convenient point for applying force, allowing easy rotation of the eccentric shaft 120 without additional tools, thus reducing the difficulty of adjustment. It increases the contact area with the hand or tools, making rotation easier and the force more even, preventing slippage or uneven force during adjustment that could cause rotational deviation of the eccentric shaft 120. This improves the stability and efficiency of the adjustment operation, indirectly ensuring the accuracy of the moving tip 220's position adjustment and optimizing the overall user experience.

[0041] like Figures 1 to 11 As shown, a tailstock assembly is provided according to a second aspect of the embodiments of this application, including: a tailstock tip adjustment device as described in any of the above technical solutions; a tailstock tip, and the tailstock tip adjustment device is connected to the tailstock tip.

[0042] The tailstock assembly provided in this application includes the tailstock tip adjustment device of any of the above-described technical solutions. Therefore, the tailstock assembly has all the beneficial effects of the tailstock tip adjustment device of the above-described technical solutions, which will not be elaborated here.

[0043] According to a third aspect of the embodiments of this application, a tailstock tip adjustment method is proposed and applied to a tailstock assembly as described in any of the above technical solutions. The adjustment method includes: driving the movable tip 220 to move along the length direction of the sleeve 210 to achieve position adjustment of the movable tip 220 in a first direction; rotating the adjustment end 121 of the tailstock tip adjustment device so that the eccentric shaft 120 drives the adjustment member 130 to move, and the adjustment member 130 contacts the movable tip 220 to achieve position adjustment of the movable tip 220 in a second direction.

[0044] The tailstock tip adjustment method provided in this application embodiment is applied to the tailstock assembly of the above-described technical solution. Therefore, the adjustment method has all the beneficial effects of the tailstock assembly of the above-described technical solution, and will not be elaborated here.

[0045] The adjustment method provided in this application embodiment achieves comprehensive and precise control over the position of the moving center 220 through a bidirectional step-by-step adjustment design. Driving the moving center 220 along the length of the sleeve 210 quickly completes the first directional (axial) position adjustment, meeting the adaptation requirements of different workpiece lengths; the operation is direct and responsive. Rotating the adjustment end 121 causes the eccentric shaft 120 to move the adjustment component 130, achieving the second directional (radial) adjustment through contact between the adjustment component 130 and the moving center 220. This accurately corrects the radial deviation of the center, solving the problem of difficult radial accuracy control in traditional adjustments. The bidirectional adjustments work together to cover the main position adjustment needs of the moving center 220, eliminating the need for complex tools and extensive experience, lowering the operational threshold, and improving adjustment efficiency. Simultaneously, the step-by-step adjustment allows operators to confirm the positional accuracy in each direction separately, reducing the cumulative error of a single adjustment, ensuring the final positioning accuracy of the center, and providing reliable assurance for key indicators such as coaxiality and perpendicularity during workpiece machining, adapting to the needs of high-precision machining scenarios.
