Description

Technical Field

[0001] This utility model relates to the field of CNC tool holder machining technology, and more specifically, to a CNC tool holder thread rolling device. Background Technology

[0002] A thread rolling device is a forming process apparatus used to process threads. It mainly consists of a rolling head equipped with three rolling shafts, on which rolling rollers are mounted. The rolling of these rollers presses the thread shape into the workpiece blank. Thread rolling does not form threads by removing metal; instead, it relies on the plastic deformation ability of the substrate to permanently press the shape of the rollers onto the workpiece. Thread rolling has many advantages, including strong threads, precise dimensions, good surface finish, low coefficient of friction, and high material utilization. In CNC tool holder machining, a thread rolling device is required to process the tool holder. For example, Chinese Patent Publication: A high-efficiency thread rolling device, application number: CN201610005083.2, includes a front end cover (2), a sliding sleeve (3), a rolling head (4), a rear end cover (5), a thread rolling device (18) and a power input shaft (9), characterized in that a sloping groove (17) is provided on the inner side of the sliding sleeve (3) below the roller frame (19) of the thread rolling device (18), an adjusting shim (16) is provided in the sloping groove (17), and an adjusting lock nut (6) is provided on the outer side of the rear end cover (5).

[0003] However, in the above-mentioned technical solutions, during the machining of CNC tool holders using thread rolling devices, it is sometimes necessary to spray lubricant to reduce friction and wear, and to reduce burrs and surface defects caused by friction and heat. However, after machining, some lubricant will still adhere to the machined CNC tool holder, which not only makes subsequent machining inconvenient, but also causes the lubricant adhering to the CNC tool holder to move to other devices as the machined CNC tool holder moves, making it impossible to recycle this part of the lubricant and resulting in waste. Utility Model Content

[0004] The main purpose of this utility model is to provide a CNC tool holder thread rolling device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A CNC tool holder thread rolling device includes a base with a machining groove on the base. A dual-axis moving table is arranged in the machining groove, and a rolling head is fixedly arranged on the dual-axis moving table. A rotating disk is rotatably arranged on one side of the machining groove. Two sliding grooves are arranged on the side of the rotating disk near the rolling head. A first baffle is slidably arranged in the sliding grooves. A first material clamp and a second material clamp are arranged between the two sliding grooves. A second baffle is arranged between the first material clamp and the second material clamp. A first motor is arranged on one side of the rotating disk, and a lubricating oil spray pipe is arranged on one side above the machining groove.

[0006] Preferably, the first material clamp and the second material clamp are rotatably connected to the rotating disk, the second baffle is fixedly connected to the rotating disk, and the first motor is fixedly mounted on the base.

[0007] Preferably, the rotating disk includes a rotating disk base, on which a first rotating column and a second rotating column are rotatably disposed, and a first gear and a second gear are respectively disposed on the first rotating column and the second rotating column.

[0008] Preferably, a third gear is meshed between the first gear and the second gear, and a third rotating column is provided on the third gear, with a second motor provided at one end of the third rotating column.

[0009] Preferably, the first rotating column is fixedly connected to the first material clamp, and the second rotating column is fixedly connected to the second material clamp.

[0010] Preferably, the second motor is fixedly mounted on the base of the rotating disk.

[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) After the processing is completed, the second motor is turned off and the rotating disk is rotated 180 degrees by the first motor, so that the position of the second material clamp and the position of the first material clamp are interchanged. Then, the first baffle moves to both sides of the first material clamp under the action of gravity. Then, the new material is put into the second material clamp and processed. During the processing, the first material clamp drives the processed material to rotate. The rotation separates the lubricating oil on the surface of the processed material, which is convenient for subsequent processing of the material. The first baffle and the second baffle block the separated lubricating oil to prevent the lubricating oil from splashing to various places, which is convenient for the lubricating oil to be recycled.

[0014] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0015] like Figure 1 and Figure 2 As shown, a CNC tool holder thread rolling device includes a base 1, a processing groove 2 on the base 1, a dual-axis moving table 3 inside the processing groove 2, a rolling head 4 fixedly mounted on the dual-axis moving table 3, a rotating disk 5 rotatably mounted on one side of the processing groove 2, two sliding grooves 6 on the side of the rotating disk 5 near the rolling head 4, a first baffle 7 slidably mounted in the sliding grooves 6, a first material clamp 8 and a second material clamp 11 mounted between the two sliding grooves 6, a second baffle 9 mounted between the first material clamp 8 and the second material clamp 11, a first motor 10 mounted on one side of the rotating disk 5, and a lubricating oil spray pipe 12 mounted on the upper side of the processing groove 2. The first motor 10 is a servo motor or a stepper motor. It achieves precise rotation angle control and position locking through an external control system (such as a PLC or CNC system). When the rotating disk 5 rotates to a predetermined position (such as 180 degrees), the first motor 10 maintains a fixed position through its self-locking function to ensure that the workpiece is stable in position during processing.

[0016] like Figure 3As shown, in another embodiment of the present invention, the rotating disk 5 includes a rotating disk base 501, and a first rotating column 502 and a second rotating column 503 are rotatably disposed on the rotating disk base 501. A first gear 504 and a second gear 505 are respectively disposed on the first rotating column 502 and the second rotating column 503. A third gear 506 is meshed between the first gear 504 and the second gear 505. A third rotating column 507 is provided on the third gear 506. A second motor 508 is provided at one end of the third rotating column 507. When it is necessary to rotate the first material clamp 8 and the second material clamp 11, the second motor 508 first rotates the third rotating column 507, which drives the third gear 506 to rotate. The third gear 506 drives the first gear 504 and the second gear 505 to rotate. The first gear 504 and the second gear 505 drive the first rotating column 502 and the second rotating column 503 to rotate. Then, the first rotating column 502 and the second rotating column 503 drive the first material clamp 8 and the second material clamp 11 to rotate.

[0017] Working principle of a CNC tool holder thread rolling device: In operation, the material is first fixed by the first material clamp 8. Then, the second motor 508 rotates the third rotating column 507, which in turn drives the third gear 506. The third gear 506 then drives the first gear 504 and the second gear 505, which in turn drive the first rotating column 502 and the second rotating column 503. The first rotating column 502 and the second rotating column 503 then drive the first material clamp 8 and the second material clamp 11 to rotate. The first material clamp 8 rotates the material, and simultaneously, the dual-axis moving table 3 moves the rolling head 4 (whose specific structure and usage have been described in detail in the comparative document and will not be repeated here) towards the material for thread rolling. During the process, lubricating oil is sprayed onto the material surface through the lubricating oil spray pipe 12. After processing, the second motor 508 is turned off, and then the first motor 10 is started, functioning as a servo or stepper motor. Under the command of the control system, the first motor 10 precisely drives the rotating disk 5 to rotate 180 degrees, and the first motor 10 also rotates the rotating disk 5 180 degrees. The first motor 10 uses its own servo locking characteristics or an external brake to keep the position fixed. At this time, the second material clamp 11 will move to the top, and the first material clamp 8 will move to the bottom, so that the positions of the second material clamp 11 and the first material clamp 8 are interchanged. Then, the first baffle 7 moves to both sides of the first material clamp 8 under the action of gravity. Then, new material is put into the second material clamp 11. The above steps are repeated to process the new material. During the processing, the first material clamp 8 drives the processed material to rotate. The rotation separates the lubricating oil from the surface of the processed material, which is convenient for subsequent reprocessing of the material. The first baffle 7 and the second baffle 9 shield the separated lubricating oil to prevent the lubricating oil from splashing everywhere and facilitate the recovery of the lubricating oil.

[0018] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
