Description

Technical Field

[0001] This application relates to the technical field of lathes, and in particular to a vibration damping device for a conventional lathe. Background Technology

[0002] A conventional lathe is a horizontal lathe capable of machining various types of workpieces such as shafts, discs, and rings using multiple processes. It is commonly used to machine the internal and external rotating surfaces, end faces, and various internal and external threads of workpieces. With appropriate cutting tools and accessories, it can also perform drilling, reaming, tapping, and knurling.

[0003] During machining on a conventional lathe, there is a tendency for vibration in both the horizontal and vertical directions. This horizontal vibration can easily cause the lathe to move, which in turn can negatively affect the machining accuracy of the workpiece. Utility Model Content

[0004] In order to reduce the adverse effects on the machining accuracy of workpieces, this application provides a vibration damping device for a conventional lathe.

[0005] The present application provides a vibration damping device for a conventional lathe, which adopts the following technical solution:

[0006] A vibration damping device for a conventional lathe includes two support plates disposed opposite each other on the lower side of the lathe body and facing the lathe body. A base plate is inserted into and slidably connected to the lower end of the support plate. A guide member is provided on the base plate to guide the lathe body. The upper end of the support plate can contact the lower side of the lathe body and support the lathe body. A drive assembly is provided on the base plate to drive the support plate to move closer to the lathe body.

[0007] By adopting the above technical solution, the lathe body vibrates during operation. The guide component causes the lathe body to always move towards or away from the base plate, reducing the possibility of the lathe body moving along the length of the base plate. At this time, the drive assembly drives the support plate to move towards the lathe body until it abuts against and supports the lower side of the lathe body, thereby providing resistance to the lathe body and reducing the possibility of the lathe body moving towards the base plate, thus reducing the adverse effects on the machining accuracy of the workpiece.

[0008] Optionally, the drive assembly includes a drive rod connected to the lower end of the oppositely disposed support plate and inserted into and slidably connected to the base plate, wherein a lead screw is inserted into and threadedly connected to the middle of the drive rod and rotatably connected to the base plate.

[0009] By adopting the above technical solution, the lead screw is rotated and the drive rod is driven to move the support plate upward until the upper side of the support plate abuts against the lower side of the lathe body and supports the lathe body. The support plate is then driven to move upward, thereby providing resistance to the lathe body, reducing the possibility of the lathe body moving towards the base plate, and reducing the adverse effects on the machining accuracy of the workpiece.

[0010] Optionally, the support plate is made of damping material, and a sliding plate is fixedly connected to each side of the support plate that is far apart from each other. The distance between the sliding plates is adapted to the width of the lathe body.

[0011] By adopting the above technical solution, the support plate moves upward and supports the lathe body. At this time, the lathe body vibrates and squeezes the support plate, the support plate deforms and generates resistance to the vibration of the lathe body, further reducing the possibility of the lathe body moving towards the base plate. During the movement of the lathe body, the sliding plate limits the lathe body along the width direction of the base plate, reducing the possibility of the lathe body deviating in the direction parallel to the base plate and reducing the adverse effects on the machining accuracy of the workpiece.

[0012] Optionally, rubber pads are installed on the side of the sliding plate closest to the lathe body.

[0013] By adopting the above technical solution, during the process of the sliding plate being limited on both sides of the lathe body, the rubber pad on the sliding plate slides on the side wall of the lathe body and generates friction, which further buffers the movement of the lathe body, reduces the possibility of the lathe body moving towards the base plate, and reduces the adverse effects on the machining accuracy of the workpiece.

[0014] Optionally, a first bevel gear is sleeved and fixedly connected to the lead screw, and a second bevel gear is meshed with one side of the first bevel gear and inserted into and rotatably connected to the base plate. The lathe body is provided with a rotating component that drives the second bevel gear to rotate.

[0015] By adopting the above technical solution, the rotating component drives the second bevel gear to rotate and drives the first bevel gear and the lead screw to rotate, which facilitates the movement of the support plate towards the lathe body, thus facilitating the support and buffering of the lathe body and reducing the adverse effects on the machining accuracy of the workpiece.

[0016] Optionally, the rotating component includes a drive gear fixedly connected to one side of the second bevel gear and coaxial with the second bevel gear, and a rack inserted into the base plate and slidably connected to the lower side of the lathe body, wherein one end of the rack inserted into the base plate meshes with the drive gear.

[0017] By adopting the above technical solution, the lathe body moves downward and drives the rack to move closer to the base plate. At this time, the drive gear drives the second bevel gear to rotate under the drive of the rack. The first bevel gear drives the lead screw to rotate under the drive of the second bevel gear, which facilitates the movement of the support plate and buffers the lathe body. When the lathe body is fully buffered, the lathe body returns to its original position and drives the lead screw to reverse through the rack, drive gear, first bevel gear and second bevel gear. At this time, the support plate moves downward and returns to its original position, which facilitates buffering the lathe body again.

[0018] Optionally, the guide is configured as a plurality of guide rods located on the lower side of the lathe body and fixedly connected at one end to the lower side of the lathe body. The lower end of the guide rod is inserted into the base plate and slidably connected to the base plate. A spring is installed between the lower side of the lathe body and the base plate.

[0019] By adopting the above technical solution, when the lathe body moves along the height direction of the base plate, it drives the guide rod to move closer to or further away from the base plate. The spring deforms as the lathe body moves, which facilitates the limiting of the lathe body while buffering the lathe body, reducing the possibility of the lathe body moving closer to the base plate and reducing the adverse effects on the machining accuracy of the workpiece.

[0020] Optionally, the diameter of the end of the guide rod inserted into the base plate is larger than the diameter of the end of the guide rod closer to the lathe body.

[0021] By adopting the above technical solution, the shape of the guide rod inserted into one end of the base plate ensures that the lower end of the guide rod is always located in the base plate during the movement of the guide rod, reducing the possibility of the guide rod detaching from the base plate, facilitating the limiting of the lathe body, and further reducing the possibility of the lathe body moving in the length direction of the base plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] During the operation of the lathe body, vibrations are generated. The guide component causes the lathe body to move towards or away from the base plate, reducing the possibility of the lathe body moving along the length of the base plate. At the same time, the drive assembly drives the support plate to move towards the lathe body until it abuts against and supports the lower side of the lathe body, thereby providing resistance to the lathe body and reducing the possibility of the lathe body moving towards the base plate.

[0024] The support plate moves upward and supports the lathe body. At this time, the lathe body vibrates and squeezes the support plate. The support plate deforms and resists the vibration of the lathe body, further reducing the possibility of the lathe body moving towards the base plate. During the movement of the lathe body, the sliding plate limits the lathe body along the width of the base plate, reducing the possibility of the lathe body shifting in the direction parallel to the base plate.

[0025] The lathe body moves downwards, causing the rack to move closer to the base plate. At this time, the drive gear drives the second bevel gear to rotate under the drive of the rack. The first bevel gear drives the lead screw to rotate under the drive of the second bevel gear, which facilitates the movement of the support plate and buffers the lathe body. When the lathe body is fully buffered, the lathe body returns to its original position and drives the lead screw to reverse through the rack, drive gear, first bevel gear and second bevel gear. At this time, the support plate moves downwards and returns to its original position, which facilitates buffering the lathe body again. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a vibration damping device for a common lathe. (Refer to...) Figure 1 and Figure 2 A vibration damping device for a conventional lathe includes a horizontal base plate 2 located below the lathe body 1 and parallel to its length. Vertical support plates 3, both located below the lathe body 1 and on both sides along the length of the base plate 2, are provided on the upper side. The support plates 3 are made of damping material. A sliding groove 21, adapted to the lower side of the support plates 3, is provided on the upper side of the base plate 2. The lower sides of the support plates 3 are inserted into the corresponding sliding grooves 21 and slidably connected to the base plate 2 in the vertical direction.

[0032] Reference Figure 2 and Figure 3 Vertical sliding plates 31 are fixedly connected to the sides of the support plates 3 that are far apart from each other. The lower side of the sliding plates 31 is level with the lower side of the support plates 3, and the upper side of the sliding plates 31 is higher than the upper side of the support plates 3. Rubber pads 32 located on the upper side of the support column are fixedly connected to the sides of the sliding plates 31 that are close to each other. The sides of the rubber pads 32 that are close to each other are in contact with the side wall of the lathe body 1.

[0033] The upper side of the support plate 3 can contact the lower side of the lathe body 1. The base plate 2 is provided with a drive assembly 4 for moving the support plate 3, and the base plate 2 is provided with a guide member 5 for guiding the lathe body 1 in the vertical direction.

[0034] During operation, the lathe body 1 vibrates. The guide 5 causes the lathe body 1 to move towards or away from the base plate 2. The sliding plate 31 limits the lathe body 1 along the width of the base plate 2, reducing the possibility of the lathe body 1 moving in the horizontal direction. At this time, the drive assembly 4 drives the support plate 3 to move towards the lathe body 1 until it abuts against and supports the lower side of the lathe body 1. At this time, the lathe body 1 vibrates and squeezes the support plate 3. The support plate 3 deforms and resists the vibration of the lathe body 1. The rubber pad 32 on the sliding plate 31 slides on the side wall of the lathe body 1 and generates friction, reducing the possibility of the lathe body 1 moving towards the base plate 2.

[0035] Reference Figure 2 and Figure 3 The guide member 5 includes multiple vertical guide rods 51 located on the lower side of the lathe body 1. In this embodiment, four guide rods 51 are evenly distributed along the four corners of the lower side of the lathe body 1, and the upper ends of the guide rods 51 are fixedly connected to the lower side of the lathe body 1. The base plate 2 has insertion slots 22 corresponding to the lower ends of the guide rods 51. The lower ends of the guide rods 51 are inserted into the corresponding insertion slots 22 and slidably connected to the base plate 2 in the vertical direction. The diameter of the end of the guide rod 51 inserted into the insertion slot 22 is larger than the diameter of the upper end of the guide rod 51. A spring 52 is sleeved on the upper end of each guide rod 51. One end of the spring 52 is fixedly connected to the lower side of the lathe body 1, and the other end is fixedly connected to the upper side of the base plate 2.

[0036] When the lathe body 1 moves, it drives the guide rod 51 to move closer to or further away from the base plate 2. The spring 52 deforms as the lathe body 1 moves, which helps to limit the lathe body 1 while buffering it. The shape of the guide rod 51 inserted into the base plate 2 ensures that the lower end of the guide rod 51 is always in the base plate 2 during the movement of the guide rod 51, reducing the possibility of the guide rod 51 detaching from the base plate 2.

[0037] Reference Figure 2 and Figure 3 The drive assembly 4 includes drive rods 41 located at both ends inside the base plate 2 and arranged along the width direction of the base plate 2. The base plate 2 has connecting grooves 23 that are adapted to the movement trajectory of the drive rods 41 and communicate with the sliding grooves 21. The connecting grooves 23 open upward and correspond one-to-one with the drive rods 41. The drive rods 41 are located in the corresponding connecting grooves 23 and are slidably connected to the base plate 2 in the vertical direction. The lower sides of the ends of the support plates 3 are fixedly connected to the ends of the drive rods 41, and a vertical lead screw 42 is threaded through and threaded to the middle of the drive rods 41 in the length direction. The lead screw 42 is located in the connecting grooves 23 and is rotatably connected to the base plate 2.

[0038] A first bevel gear 43 located in the connecting groove 23 is sleeved and fixedly connected to the lower end of the lead screw 42. A second bevel gear 44 rotatably connected to the side wall of the base plate 2 is meshed on one side of the first bevel gear 43. The lathe body 1 is provided with a rotating component 45 corresponding to and driving the second bevel gear 44 to rotate. The rotating component 45 includes a drive gear 451 fixedly connected to one side of the second bevel gear 44 and coaxial with the second bevel gear 44. The drive gear 451 is rotatably connected to the inner side wall of the base plate 2, and a vertical rack 452 is fixedly connected to the lower end of the lathe body 1. The lower end of the rack 452 is inserted into the connecting groove 23 and meshes with the drive gear 451.

[0039] The lathe body 1 moves downward and drives the rack 452 to move closer to the base plate 2. At this time, the drive gear 451 drives the second bevel gear 44 to rotate under the drive of the rack 452. At this time, the first bevel gear 43 drives the lead screw 42 to rotate under the drive of the second bevel gear 44, which facilitates the movement of the drive support plate 3 and buffers the lathe body 1. When the lathe body 1 is fully buffered, the lathe body 1 returns to its original position and drives the lead screw 42 to reverse through the rack 452, drive gear 451, first bevel gear 43 and second bevel gear 44. At this time, the support plate 3 moves downward and returns to its original position.

[0040] The implementation principle of a shock-absorbing device for a conventional lathe according to an embodiment of this application is as follows: the lathe body 1 moves downward and drives the rack 452 to move closer to the base plate 2. At this time, the drive gear 451 drives the second bevel gear 44 to rotate under the drive of the rack 452. At this time, the first bevel gear 43 drives the lead screw 42 to rotate under the drive of the second bevel gear 44, which facilitates the movement of the drive support plate 3 and buffers the lathe body 1.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
