Description

Technical Field

[0001] The present application relates to the field of cutting devices, and in particular to a tooling device for processing round tubes. Background Art

[0002] Currently, lathes generally process workpieces by external cutting. The main working method is to clamp the workpiece with a clamping member on one side, and then gradually move a cutting tool closer to the workpiece side by side, so that the cutting tool contacts the workpiece, and then the cutting process of the workpiece is realized during the rotation of the workpiece.

[0003] When it is necessary to cut the inside of a cylindrical workpiece, the above method is still used for cutting, but the problem is that only annular grooves can be cut on the workpiece, and it is difficult to perform the processing operation of arc grooves on the inner wall of the workpiece. Summary of the Utility Model

[0004] In order to realize the processing operation of arc grooves on the inner wall of a cylindrical workpiece, the present application provides a tooling device for processing round tubes.

[0005] The tooling device for processing round tubes provided by the present application adopts the following technical solutions:

[0006] A tooling device for processing round tubes includes a clamping member for clamping a workpiece. One side of the clamping member is connected with a motor for driving the clamping member to rotate. A cutter shaft is arranged on the side of the clamping member away from the motor. A cutting tool is fixedly connected to the side wall of the cutter shaft near one end of the clamping member. A linkage assembly is connected between the cutter shaft and the clamping member. The linkage assembly can drive the cutting tool to move towards the direction close to the clamping member during the rotation of the clamping member.

[0007] By adopting the above technical solutions, during actual use, the workpiece is clamped by the clamping member, and then the motor drives the clamping member to rotate. During the rotation of the clamping member, the connected cutter shaft is driven to move by the linkage assembly. During the movement of the cutter shaft, the cutting tool is driven to be inserted into the workpiece and abuts against the inner wall of the workpiece. Then, as the clamping member continues to rotate, the cutting tool is further driven to move into the workpiece. At the same time, the workpiece continues to rotate, so as to realize the cutting process of arc-shaped cut grooves on the inner wall of the workpiece.

[0008] Optionally, the clamping member is set as a three-jaw chuck.

[0009] By adopting the above technical solutions, the workpiece is clamped by setting a three-jaw chuck, so that the center line of the workpiece can be more accurately aligned with the center line of the cutter shaft, thereby reducing the occurrence of the phenomenon that the cutting tool is difficult to contact the inner wall of the workpiece.

[0010] Optionally, an installation block is fixedly connected to the side of the cutter shaft away from the clamping member. A base is provided below the installation block, and the installation block is slidably connected to the base.

[0011] By adopting the above technical solution, by setting the installation block and making the installation block slidably connected to the base, the phenomenon that the position of the cutter deviates during the contact between the cutter and the workpiece, resulting in poor quality of the cut groove, is reduced.

[0012] Optionally, the linkage assembly includes a driving gear connected to the three-jaw chuck and capable of rotating driven by the three-jaw chuck. The driving gear meshes with a driving rack. The side of the driving rack away from the driving gear is connected to the cutter shaft and capable of driving the cutter shaft to move towards the side close to the clamping member.

[0013] By adopting the above technical solution, during the rotation of the three-jaw chuck driven by the motor, the three-jaw chuck drives the connected driving gear to rotate. During the rotation of the driving gear, it drives the connected driving rack to move. During the movement of the driving rack, it drives the connected cutter shaft to move, thereby realizing the process of driving the cutter to move through the linkage assembly while the three-jaw chuck rotates.

[0014] Optionally, a driven bevel gear is fixedly connected to one side of the driving gear. A driving bevel gear meshes with one side of the driven bevel gear. The driving bevel gear is fixedly connected to the clamping member and capable of rotating driven by the clamping member.

[0015] By adopting the above technical solution, during the rotation of the three-jaw chuck, it drives the connected driving bevel gear to rotate. During the rotation of the driving bevel gear, it drives the connected driven bevel gear to rotate. During the rotation of the driven bevel gear, it drives the connected driving gear to rotate, thereby realizing the process of driving the connected driving gear to rotate through the rotation of the three-jaw chuck.

[0016] Optionally, a connecting plate is provided on the side of the rack away from the driving gear. The connecting plate is arranged parallel to the rack. One end of the connecting plate close to the driving rack is connected to the driving rack through a connecting bolt. The end of the connecting plate away from the driving rack is connected to the cutter shaft and capable of driving the cutter shaft to move.

[0017] By adopting the above technical solution, by setting the connecting plate and connecting the driving rack and the cutter shaft through the connecting bolt, the phenomenon that when the side wall of the cutter shaft and the driving gear are not in the same plane, the driving rack needs to be inclined to connect the driving gear and the cutter shaft, thereby affecting the movement of the driving rack, is reduced.

[0018] Optionally, a limiting component is connected between the mounting block and the base, and the limiting component is used to limit the displacement of the mounting block.

[0019] By adopting the above technical solution, by setting the limiting component, the phenomenon that the cutter shaft is displaced during movement, resulting in the cutter being difficult to insert into the workpiece and abut against the inner wall of the workpiece, is reduced.

[0020] Optionally, the limiting component includes a plurality of sliders fixedly connected to the bottom of the mounting block, and a slide rail is fixedly connected to the upper side of the base. The slide rail is for the sliders to be inserted and move in the direction close to the clamping member.

[0021] By adopting the above technical solution, by setting the sliders and the slide rails connected to the sliders, the cutter shaft can move along the length direction of the slide rail during movement, thereby realizing the limitation of the movement path of the mounting block.

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

[0023] 1. By setting the linkage component, the three-jaw chuck drives the cutter to move in the direction close to the three-jaw chuck during rotation, thereby realizing the cutting of the arc-shaped cutting groove on the inner wall of the workpiece;

[0024] 2. By setting the linkage component to drive the cutter to move, the waste of resources for setting a driving device to drive the cutter to move is reduced;

[0025] 3. By setting the limiting component, the movement path of the cutter can be limited, and the phenomenon that the cutter is displaced during actual use, thereby affecting the cutting process of the inner wall of the workpiece, is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

Specific Embodiments

[0030] The following will further elaborate on this application in conjunction with the Figure 1 - attached Figure 3 drawings.

[0031] An embodiment of this application discloses a tooling device for processing circular tubes. Referring to Figure 1 、 Figure 2 and Figure 3 , it includes a base 1, and a clamping member 2 is provided on one side above the base 1. In this embodiment, the clamping member 2 is set as a three-jaw chuck 21, and the three-jaw chuck 21 is vertically arranged. A motor 3 is provided on the non-clamping side of the three-jaw chuck 21. The motor 3 is connected to a speed reducer 31, and the speed reducer 31 is fixedly connected to the three-jaw chuck 21.

[0032] A cutter shaft 4 is provided on the side of the three-jaw chuck 21 away from the motor 3. The cutter shaft 4 is horizontally arranged and extends from the side close to the three-jaw chuck 21 to the side away from the three-jaw chuck 21. A cutter 41 is fixedly connected to the side wall of one end of the cutter shaft 4 close to the three-jaw chuck 21.

[0033] One end of the cutter shaft 4 away from the end connected to the cutter 41 is fixedly connected to a mounting block 5, and a linkage assembly 6 is connected between the mounting block 5 and the three-jaw chuck 21. The linkage assembly 6 is used to drive the mounting block 5 to move towards the direction close to the three-jaw chuck 21 during the rotation of the three-jaw chuck 21.

[0034] During actual use, the cylindrical workpiece is clamped inside by the three-jaw chuck 21. Then, the motor 3 is started. During the rotation of the motor 3, the connected three-jaw chuck 21 is driven to rotate through the speed reducer 31. During the rotation of the three-jaw chuck 21, the clamped cylindrical workpiece is driven to rotate. At the same time, while the three-jaw chuck 21 is rotating, the mounting block 5 is driven to move towards the direction close to the three-jaw chuck 21 through the linkage assembly 6.

[0035] During the movement of the mounting block 5, the connected cutter shaft 4 and the cutter 41 are driven to move towards the direction close to the workpiece, and the cutter shaft 4 can be inserted into the workpiece while the cutter 41 can be in contact with the inner wall of the workpiece, so that during the movement of the cutter 41 towards the direction close to the three-jaw chuck 21, as the workpiece rotates, an arc-shaped cut groove can be cut on the inner wall of the workpiece by the cutter 41.

[0036] The linkage assembly 6 includes a driving bevel gear 61 fixedly connected to the side of the three-jaw chuck 21 close to the motor 3. One side of the driving bevel gear 61 meshes with a driven bevel gear 62. The side of the driven bevel gear 62 away from the three-jaw chuck 21 is fixedly connected to a driving gear 63. The upper side of the driving gear 63 meshes with a driving rack 64. The driving rack 64 is horizontally arranged and extends in the length direction from the side close to the three-jaw chuck 21 to the side close to the mounting block 5. The side of the driving gear 63 away from the driving rack 64 is connected to the mounting block 5 and can drive the mounting block 5 to move towards the three-jaw chuck 21.

[0037] During the process of the motor 3 driving the three-jaw chuck 21 to rotate, the three-jaw chuck 21 drives the connected driving bevel gear 61 to rotate. During the rotation of the driving bevel gear 61, it drives the connected driven bevel gear 62 to rotate. During the rotation of the driven bevel gear 62, it drives the connected driving gear 63 to rotate. During the rotation of the driving gear 63, it drives the connected driving rack 64 to move. During the movement of the driving rack 64, it drives the connected mounting block 5 to move. Thus, during the rotation of the three-jaw chuck 21, the cutting tool 41 connected is driven to move through the linkage assembly 6.

[0038] On the upper side of the end of the linkage rack away from the driving gear 63, there is a connecting plate 65. The connecting plate 65 is arranged parallel to the driving rack 64 and the end of the connecting plate 65 in contact with the driving rack 64 is penetrated and connected with the same connecting bolt 651.

[0039] By arranging the connecting plate 65 and the connecting bolt 651, on the one hand, the use of the driving rack 64 can be reduced, saving the overall cost. On the other hand, since the connecting plate 65 and the driving rack 64 are connected by the connecting bolt 651, when there is a certain angle between the driving rack 64 and the connecting plate 65, the driving rack 64 can still drive the connecting plate 65 and the mounting block 5 connected to the connecting plate 65 to move, thus realizing the protection of the driving rack 64.

[0040] A limiting component 7 is also connected between the mounting block 5 and the base 1. The limiting component 7 is used to limit the movement path of the mounting block 5, so that the mounting block 5 can only move linearly towards the three-jaw chuck 21.

[0041] By arranging the limiting component 7, the movement path of the mounting block 5 can be limited, and further the movement path of the cutting tool 41 can be limited, making the cutting of the workpiece clamped by the three-jaw chuck 21 by the cutting tool 41 more accurate.

[0042] The limiting component 7 includes a plurality of sliders 71 fixedly connected to the bottom of the mounting block 5. In this embodiment, the number of sliders 71 is set to two, and the two sliders 71 are arranged oppositely. A slide rail 72 is provided on the lower side of the mounting block 5, and the length direction of the slide rail 72 extends linearly from the three-jaw chuck 21 to the lower side of the mounting block 5. Two chutes 721 having the same length direction as the sliders 71 are formed on the upper side of the slide rail 72. The two chutes 721 are arranged in one-to-one correspondence with the two sliders 71, and each slider 71 is inserted into the corresponding chute 721 and is in sliding contact with the side wall of the chute 721.

[0043] By providing the sliders 71 and the slide rail 72, the mounting block 5 can be limited by the sliders 71 and the slide rail 72 during the movement process, so that the mounting block 5 moves along the length direction of the slide rail 72. Furthermore, the cutter shaft 4 can drive the cutter 41 to be inserted into the middle position of the workpiece to cut the inner wall of the workpiece.

[0044] The implementation principle of a tooling device for processing a circular tube in an embodiment of the present application is as follows: during actual use, first, the cylindrical workpiece is clamped by the three-jaw chuck 21, and then the motor 3 is started to drive the three-jaw chuck 21 to rotate. During the rotation of the three-jaw chuck 21, the mounting block 5 is driven to move in a direction close to the three-jaw chuck 21.

[0045] After the cutter 41 abuts against the inner wall of the workpiece during the movement process, with the movement of the mounting block 5 and the rotation of the workpiece, the cutter 41 can cut the inner wall of the three-jaw chuck 21, and the cutting groove is arc-shaped.

[0046] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
