Description

Technical Field

[0001] This utility model belongs to the field of lathe technology, and specifically relates to a workpiece end face machining device and a lathe. Background Technology

[0002] In the field of lathe technology, related technologies require the use of a cutting tool to machine the end face of the workpiece (the side of the workpiece away from the spindle). Specifically, the related technologies machine the end face of the workpiece by driving the cutting tool to move radially toward the workpiece along the spindle. After machining, the cutting tool needs to be reset (the cutting tool moves radially away from the workpiece along the spindle). However, when the cutting tool begins to reset, it is still in contact with the end face of the workpiece. Therefore, the related technologies have the problem that the end face of the workpiece is worn and scratched because the cutting tool is still in contact with the end face of the workpiece when it begins to reset, resulting in the production of defective products.

[0003] Therefore, the existing technology needs improvement and development. It should be noted that the information disclosed in this section is only for understanding the background of the present invention, and therefore may include information that does not constitute prior art. Utility Model Content

[0004] The purpose of this application is to provide a workpiece end face machining device and a lathe for a lathe, which can avoid the situation where the end face of the workpiece is scratched due to the contact between the machining tool and the end face of the workpiece during the resetting process.

[0005] In a first aspect, this application provides a workpiece end face machining apparatus for a lathe, the lathe including a spindle for clamping the workpiece to be machined, and the workpiece end face machining apparatus for the lathe including:

[0006] The bracket is slidably mounted on the lathe frame;

[0007] The machining tool is slidably mounted on the bracket;

[0008] An axial drive assembly, mounted on a bracket, is used to drive the machining tool to move toward or away from the workpiece along the spindle axis;

[0009] A radial drive assembly, mounted on the lathe frame and connected to a support, is used to drive the support to move radially toward or away from the workpiece along the spindle.

[0010] This application provides a lathe workpiece end face machining device that can move the machining tool away from the end face of the workpiece by using the axial drive component to drive the machining tool along the spindle axis away from the workpiece before the radial drive component resets. This ensures that the machining tool cannot contact the end face of the workpiece when the radial drive component starts to reset. Therefore, this application can effectively avoid the situation where the end face of the workpiece is worn or scratched due to the machining tool still contacting the end face of the workpiece when the radial drive component starts to reset, thus effectively avoiding the production of defective products due to scratched end face of the workpiece.

[0011] Furthermore, the axial drive assembly includes an elastic element and a linear drive mechanism. The two ends of the elastic element are connected to one side of the support and one side of the machining tool, respectively. The other side of the machining tool abuts against the output end of the linear drive mechanism under the elastic action of the elastic element.

[0012] Furthermore, the workpiece end face machining device of the lathe also includes a first limiting component, which is mounted on a bracket. When machining the end face of the workpiece to be machined, the first limiting component abuts against the machining tool.

[0013] Because the linear drive mechanism may not be able to move the machining tool to the same position each time it moves along the spindle axis toward the workpiece under the action of the elastic element, the first limiting component of this technical solution can abut against the machining tool when the end face of the workpiece is being machined. Therefore, this technical solution can use the first limiting component and the linear drive mechanism to clamp and limit the position of the machining tool to ensure that the machining tool is moved to the same position each time it moves along the spindle axis toward the workpiece, thereby effectively improving the machining consistency of the end face of the workpiece.

[0014] Furthermore, the workpiece end face machining device of the lathe also includes a second limiting component, which is used to limit the maximum distance between the machining tool and the spindle in the spindle axis.

[0015] Furthermore, the radial drive assembly includes a motor, a lead screw, and a nut. Both the motor and the lead screw are mounted on the lathe frame. The nut is threaded to the lead screw and fixedly connected to the bracket. The motor is used to drive the lead screw to rotate.

[0016] Furthermore, the workpiece end face machining device of the lathe also includes a first anti-collision component and a second anti-collision component, both of which are sleeved on the outside of the lead screw, and the nut is located between the first anti-collision component and the second anti-collision component.

[0017] The first and second anti-collision components of this technical solution can both be anti-collision blocks. Both the first and second anti-collision components can prevent damage to the nut or lathe due to collision between the nut and the lathe. In other words, this technical solution can protect the nut and the lathe by using the first and second anti-collision components.

[0018] Furthermore, a sliding protrusion is provided on the side of the machining tool away from the spindle, and the bracket is provided with a sliding groove that matches the sliding protrusion. The sliding groove is a dovetail groove.

[0019] Because the machining tool of this technical solution has a sliding protrusion on the side away from the spindle, and the bracket has a sliding groove that matches the sliding protrusion, and the sliding groove is a dovetail groove, that is, the sliding groove can limit and guide the sliding protrusion. Therefore, this technical solution can effectively avoid the situation where the end face machining of the workpiece is affected due to the unexpected deviation of the machining tool when it moves along the spindle axis.

[0020] Furthermore, the bracket includes a first mounting bracket and a second mounting bracket. The machining tool and the axial drive assembly are both mounted on the second mounting bracket. The first mounting bracket has threaded holes, and the second mounting bracket has obliquely arranged striped holes. The second mounting bracket can be locked and fixed on the first mounting bracket by the engagement of bolts passing through the striped holes and the threaded holes.

[0021] Furthermore, the axial drive assembly includes a cylinder.

[0022] Secondly, the present invention provides a lathe that includes a workpiece end face machining device for the lathe provided in the first aspect.

[0023] This application provides a lathe that, before the radial drive assembly resets, drives the machining tool to move away from the end face of the workpiece along the spindle axis using an axial drive assembly. This ensures that the machining tool cannot contact the end face of the workpiece when the radial drive assembly begins to reset. Therefore, this application effectively avoids wear and scratches on the end face of the workpiece caused by the machining tool still contacting it when the radial drive assembly begins to reset, thus effectively preventing the production of defective products due to scratches on the end face of the workpiece.

[0024] As can be seen from the above, the workpiece end face machining device and lathe provided by this utility model can move the machining tool away from the end face of the workpiece by using the axial drive component to drive the machining tool to move away from the workpiece along the spindle axis before the radial drive component resets. This ensures that the machining tool cannot contact the end face of the workpiece when the radial drive component starts to reset. Therefore, this application can effectively avoid the situation where the end face of the workpiece is worn or scratched due to the machining tool still contacting the end face of the workpiece when the radial drive component starts to reset. This effectively avoids the situation where defective products are produced due to the end face of the workpiece being scratched. Attached Figure Description

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0032] Firstly, such as Figures 1-4 As shown, this application provides a workpiece end face machining apparatus for a lathe. The lathe includes a spindle for clamping the workpiece to be machined, and the workpiece end face machining apparatus for the lathe includes:

[0033] Bracket 2 is slidably mounted on lathe frame 1;

[0034] The machining tool 3 is slidably mounted on the bracket 2;

[0035] Axial drive assembly 4, mounted on bracket 2, is used to drive machining tool 3 to move toward or away from the workpiece along the spindle axis;

[0036] The radial drive assembly 7 is mounted on the lathe frame 1 and connected to the bracket 2, and is used to drive the bracket 2 to move radially toward or away from the workpiece to be processed along the spindle.

[0037] The lathe provided in this embodiment includes a spindle for clamping the workpiece to be processed. After clamping the workpiece, the workpiece end face machining device of the lathe in this embodiment can machine the end face of the workpiece (the side of the workpiece away from the spindle). The machining tool 3 in this embodiment can be an existing tool used for machining the end face of the workpiece. The machining tool 3 in this embodiment is slidably mounted on the bracket 2, that is, the machining tool 3 in this embodiment can slide relative to the bracket 2. The axial drive assembly 4 in this embodiment is mounted on the bracket 2. The axial drive assembly 4 can be a cylinder, hydraulic cylinder, or electric cylinder, etc., that can drive the machining tool 3 to move toward or away from the workpiece along the spindle axial direction (equivalent to the horizontal direction). In this embodiment, the radial drive assembly 7 can be a component such as a cylinder, hydraulic cylinder, or electric cylinder that can drive the linear movement of an object. In this embodiment, the radial drive assembly 7 is mounted on the lathe frame 1 and connected to the bracket 2. Since the machining tool 3 is mounted on the bracket 2, this embodiment can drive the machining tool 3 to move radially toward or away from the workpiece along the spindle by controlling the radial drive assembly 7 to drive the bracket 2 to move radially toward or away from the workpiece. The driving direction of the axial drive assembly 4 is perpendicular to the driving direction of the radial drive assembly 7.

[0038] Specifically, the process of machining the end face of the lathe in this embodiment can be as follows: after the spindle clamps the workpiece, the axial drive assembly 4 drives the machining tool 3 to move along the spindle axis toward the workpiece until the machining tool 3 moves to a preset machining position (the horizontal position of the machining tool 3 when machining the end face of the workpiece); the radial drive assembly 7 drives the machining tool 3 to move radially toward the workpiece to machine the end face of the workpiece; after the end face machining of the workpiece is completed, the axial drive assembly 4 drives the machining tool 3 to move away from the workpiece along the spindle axis so that the machining tool 3 does not contact the end face of the workpiece; the radial drive assembly 7 drives the machining tool 3 to move radially away from the workpiece along the spindle axis to reset the machining tool 3.

[0039] This application provides a lathe workpiece end face machining device that can drive the machining tool 3 away from the end face of the workpiece along the spindle axis by using the axial drive component 4 to move the machining tool 3 away from the end face of the workpiece before the radial drive component 7 resets. This ensures that the machining tool 3 cannot contact the end face of the workpiece when the radial drive component 7 starts to reset. Therefore, this application can effectively avoid the situation where the end face of the workpiece is worn or scratched due to the machining tool 3 still contacting the end face of the workpiece when the radial drive component 7 starts to reset, thus effectively avoiding the production of defective products due to scratched end face of the workpiece.

[0040] In some preferred embodiments, the axial drive assembly 4 includes an elastic element 41 and a linear drive mechanism 42. The two ends of the elastic element 41 are connected to one side of the support 2 and one side of the machining tool 3, respectively. The other side of the machining tool 3 abuts against the output end of the linear drive mechanism 42 under the elastic action of the elastic element 41. In this embodiment, the elastic element 41 is preferably a spring. When there is no need to machine the end face of the workpiece, the elastic element 41 is in a compressed state. The linear drive mechanism 42 in this embodiment is preferably a cylinder. Since the elastic element 41 is in a compressed state when there is no need to machine the end face of the workpiece, this embodiment can use the elastic force provided by the elastic element 41 to drive the machining tool 3 to return to its axial position along the spindle. Therefore, the output end of the linear drive mechanism 42 in this embodiment does not need to be fixedly connected to the machining tool 3.

[0041] In some preferred embodiments, the lathe workpiece end face machining device further includes a first limiting component 5, which is mounted on the bracket 2. When machining the end face of the workpiece, the first limiting component 5 abuts against the machining tool 3. In this embodiment, the first limiting component 5 is preferably a limiting screw. Because the linear drive mechanism 42 may not be able to move the machining tool 3 to the same position each time it moves along the spindle axis towards the workpiece under the action of the elastic element 41, this embodiment's first limiting component 5 can abut against the machining tool 3 when machining the end face of the workpiece. Therefore, this embodiment can use the first limiting component 5 and the linear drive mechanism 42 to clamp and limit the position of the machining tool 3, ensuring that the machining tool 3 is moved to the same position each time it moves along the spindle axis towards the workpiece, thereby effectively improving the machining consistency of the end face of the workpiece. Furthermore, because this embodiment can fix the machining tool 3 and improve its stability through the first limiting component 5 and the linear drive mechanism 42, this embodiment allows the machining tool 3 to smoothly machine the end face of the workpiece.

[0042] In some preferred embodiments, the workpiece end face machining device of the lathe further includes a second limiting component 6, which is used to limit the maximum distance between the machining tool 3 and the spindle in the spindle axial direction. This embodiment is equivalent to using the second limiting component 6 to limit the initial position of the machining tool 3. Preferably, the axial drive component 4 in this embodiment includes an elastic element 41 and a linear drive mechanism 42, which is a cylinder. The second limiting component 6 in this embodiment is a nut 73 threadedly connected to the cylinder. This embodiment can limit the maximum distance between the machining tool 3 and the spindle in the spindle axial direction by causing the nut 73 to abut against the piston end of the cylinder.

[0043] In some preferred embodiments, the radial drive assembly 7 includes a motor 71, a lead screw 72, and a nut 73. Both the motor 71 and the lead screw 72 are mounted on the lathe frame 1. The nut 73 is threadedly connected to the lead screw 72 and fixedly connected to the bracket 2. The motor 71 drives the lead screw 72 to rotate. In this embodiment, the motor 71 is preferably connected to the lead screw 72 via a synchronous belt. Because the nut 73 is threadedly connected to the lead screw 72, this embodiment can drive the nut 73 to move on the lead screw 72 by using the motor 71 to drive the lead screw 72 to rotate, thereby driving the bracket 2 to move radially toward or away from the workpiece along the spindle.

[0044] In some preferred embodiments, the workpiece end face machining device of the lathe further includes a first anti-collision component 8 and a second anti-collision component 9. Both the first anti-collision component 8 and the second anti-collision component 9 are sleeved outside the lead screw 72, and the nut 73 is located between the first anti-collision component 8 and the second anti-collision component 9. In this embodiment, both the first anti-collision component 8 and the second anti-collision component 9 can be anti-collision blocks. In this embodiment, both the first anti-collision component 8 and the second anti-collision component 9 can prevent damage to the nut 73 or the lathe frame 1 due to collision with it. That is, this embodiment can protect the nut 73 and the lathe frame 1 using the first anti-collision component 8 and the second anti-collision component 9.

[0045] In some preferred embodiments, the machining tool 3 has a sliding protrusion 10 on the side away from the spindle, and the support 2 has a sliding groove 11 that matches the sliding protrusion 10. The sliding groove 11 is a dovetail groove. Since the machining tool 3 in this embodiment has a sliding protrusion 10 on the side away from the spindle, and the support 2 has a sliding groove 11 that matches the sliding protrusion 10, and the sliding groove 11 is a dovetail groove, the sliding groove 11 can limit and guide the sliding protrusion 10. Therefore, this embodiment can effectively avoid the situation where the end face machining of the workpiece is affected due to the unexpected deviation of the machining tool 3 when moving along the spindle axis.

[0046] In some preferred embodiments, the bracket 2 includes a first mounting bracket 21 and a second mounting bracket 22. The machining tool 3 and the axial drive assembly 4 are both mounted on the second mounting bracket 22. The first mounting bracket 21 has threaded holes, and the second mounting bracket 22 has obliquely arranged striped holes 12. The second mounting bracket 22 can be locked and fixed to the first mounting bracket 21 by the engagement of bolts 13 passing through the striped holes 12 and the threaded holes. Since the second mounting bracket 22 in this embodiment has obliquely arranged striped holes, when the second mounting bracket 22 is not locked and fixed to the first mounting bracket 21, this embodiment can adjust the orientation of the machining tool 3 by swinging the second mounting bracket 22 on the first mounting bracket 21, so that the lathe workpiece end face machining device can meet the process requirements of different machining directions.

[0047] In some preferred embodiments, the axial drive assembly 4 includes a cylinder.

[0048] As can be seen from the above, the lathe workpiece end face machining device provided in this application can drive the machining tool 3 to move away from the end face of the workpiece along the spindle axis by using the axial drive component 4 before the radial drive component 7 is reset, so that the machining tool 3 cannot contact the end face of the workpiece when the radial drive component 7 starts to reset. Therefore, this application can effectively avoid the situation where the end face of the workpiece is worn or scratched due to the machining tool 3 still contacting the end face of the workpiece when the radial drive component 7 starts to reset, thereby effectively avoiding the situation where defective products are produced due to the end face of the workpiece being scratched.

[0049] Secondly, the present invention provides a lathe that includes a workpiece end face machining device for the lathe provided in the first aspect.

[0050] This application provides a lathe, which includes the workpiece end face machining device of the lathe provided in the first aspect above. The principle of the lathe provided in this embodiment is the same as that of the workpiece end face machining device of the lathe provided in the first aspect above, and will not be discussed in detail here.

[0051] As can be seen from the above, the workpiece end face machining device and lathe provided by this utility model can move the machining tool 3 away from the end face of the workpiece by using the axial drive component 4 to drive the machining tool 3 to move away from the workpiece along the spindle axis before the radial drive component 7 is reset. This ensures that the machining tool 3 cannot contact the end face of the workpiece when the radial drive component 7 starts to reset. Therefore, this application can effectively avoid the situation where the end face of the workpiece is worn or scratched due to the machining tool 3 still contacting the end face of the workpiece when the radial drive component 7 starts to reset. This effectively avoids the situation where defective products are produced due to the end face of the workpiece being scratched.
