Description

Technical Field

[0001] This utility model relates to the field of turret milling machines, specifically a vertical turret milling machine with a buffer function. Background Technology

[0002] Vertical turret milling machines, also known as radial milling machines or universal milling machines, are a type of turret milling machine belonging to the milling machine category. They are lightweight, general-purpose metal cutting machine tools. The main difference between vertical turret milling machines and traditional turret milling machines is that the spindle can only feed vertically, and the spindle's travel direction forms a 90° angle with the worktable plane, hence the name "vertical turret milling machine." They have both vertical and horizontal milling capabilities and are widely used in industries such as machining, mold making, instrumentation, and metering.

[0003] However, most vertical turret milling machines currently on the market do not have a buffer function when the cutter head is drilling holes in the mold. The cutter head is prone to damage after long-term use, which greatly reduces the service life of the device. Utility Model Content

[0004] (1) Technical problems solved

[0005] To address the shortcomings of existing technologies, this utility model provides a vertical turret milling machine with a buffer function. This machine provides a buffer when the cutter head is drilling a die, reducing the likelihood of damage to the cutter head during prolonged use and extending the service life of the device. This solves the problem of the lack of a buffer function when the cutter head is drilling a die, which leads to easy damage to the cutter head during prolonged use and significantly reduces the service life of the device.

[0006] (2) Technical solution

[0007] To achieve the aforementioned buffering function when the cutter head drills a mold, preventing damage to the cutter head during prolonged use and extending the service life of the device, this utility model provides the following technical solution: A vertical turret milling machine with buffering function, comprising a base, a shock-absorbing column, a first expansion bolt, and a second expansion bolt. A worktable is fixedly connected to the top of the base, and a drive mechanism is fixedly connected to the top of the worktable. A hydraulic cylinder body is disposed on one side of the drive mechanism, and a cutter head is fixedly connected to the bottom of the hydraulic cylinder body. A top shock-absorbing plate is fixedly sleeved on the outer wall of the hydraulic cylinder body, and a bottom shock-absorbing plate is fixedly sleeved on the outer wall of the cutter head. A threaded groove is formed on the eastern side of the shock-absorbing column. A damping shock absorber is fixedly connected to the inner bottom wall of the threaded groove. A damping spring is fixedly connected to the top of the damping shock absorber. A threaded column is fixedly connected to the top of the damping spring. Through the arrangement of the top damping plate, bottom damping plate, column, damping device, and spring, the threaded column increases resistance through the threads when moving into the threaded groove, thus playing a certain buffering role. This reduces the vibration force on the damping shock absorber. The damping shock absorber can play an effective damping and buffering role when subjected to vibration force. Through multiple damping and buffering effects, the cutter head can play a good buffering function. The cutter head is not easy to be damaged after long-term use, thus extending the service life of the device.

[0008] In a preferred embodiment of this invention, the outer wall of the threaded post is threadedly connected to the inner wall of the threaded groove, thus providing a certain buffering effect.

[0009] As a preferred technical solution of this utility model, a bearing is fixedly connected to the top of the threaded column, a top mounting block is fixedly connected to the inner ring of the bearing, and a first mounting channel is opened on the top of the top damping plate. The first mounting channel is slidably sleeved with a first expansion bolt, and the first expansion bolt can be installed and removed through the first mounting channel on the top damping plate.

[0010] As a preferred embodiment of this utility model, the bottom of the first expansion bolt extends into the interior of the top mounting block, and the first expansion bolt is threadedly connected to the top mounting block. The stability of the top mounting block installation is improved by the first expansion bolt.

[0011] As a preferred technical solution of this utility model, the bottom of the shock-absorbing column is fixedly connected to a bottom mounting block, and the bottom of the bottom shock-absorbing plate is provided with a second mounting channel. The second mounting channel is slidably sleeved with a second expansion bolt, and the second expansion bolt can be installed and removed through the second mounting channel on the bottom mounting block.

[0012] As a preferred technical solution of this utility model, the bottom of the second expansion bolt extends into the interior of the bottom mounting block, and the second expansion bolt is threadedly connected to the bottom mounting block. The stability of the bottom mounting block installation is improved by the provision of the second expansion bolt.

[0013] (3) Beneficial effects

[0014] Compared with the prior art, this utility model provides a vertical turret milling machine with a buffer function, which has the following beneficial effects:

[0015] 1. Through the installation of top damping plate, bottom damping plate, building column, damping device and building spring, the threaded column will increase the resistance through the thread when moving into the thread groove, thereby playing a certain buffering role. This will reduce the vibration force on the damping damper. The damping damper can play an effective damping and buffering role when subjected to vibration force. Through multiple damping and buffering effects, the cutter head can play a good buffering function. The cutter head is not easy to be damaged after long-term use, thus extending the service life of the device.

[0016] 2. By using the first expansion bolt, the second expansion bolt, the top mounting block, and the bottom mounting block, when the thread of the first expansion bolt is inside the top mounting block, one end of the first expansion bolt will expand inside the top mounting block, thus preventing the first expansion bolt from automatically reversing and detaching from the top mounting block. Similarly, when the thread of the second expansion bolt is inside the bottom mounting block, one end of the second expansion bolt will expand inside the bottom mounting block, thus preventing the second expansion bolt from automatically reversing and detaching from the bottom mounting block. This improves the stability of the installation of the top and bottom mounting blocks. Attached Figure Description

[0023] Example 1

[0024] Reference Figure 1-4 This first embodiment of the present invention provides a vertical turret milling machine with a buffer function, including a base 1, a shock-absorbing column 9, a first expansion bolt 17, and a second expansion bolt 19. A worktable 2 is fixedly connected to the top of the base 1, and a drive mechanism 3 is fixedly connected to the top of the worktable 2. A hydraulic cylinder body 4 is provided on one side of the drive mechanism 3, and a cutter head 5 is fixedly connected to the bottom of the hydraulic cylinder body 4. The part to be processed is placed on the top of the worktable 2, and the base 1 controls the operation of the drive mechanism 3 and the hydraulic cylinder body 4. The operation of the drive mechanism 3 and the hydraulic cylinder body 4 is... The cutting head 5 is driven to process parts according to work requirements. The outer wall of the hydraulic cylinder body 4 is fixedly sleeved with a top damping plate 6, and the outer wall of the cutting head 5 is fixedly sleeved with a bottom damping plate 7. A threaded groove 10 is opened on the eastern side of the damping column 9. A damping shock absorber 11 is fixedly connected to the inner bottom wall of the threaded groove 10. The damping shock absorber 11 is an existing device and will not be explained in detail here. The damping shock absorber 11 can play an effective role in damping and buffering when subjected to vibration force. A damping spring 12 is fixedly connected to the top of the damping shock absorber 11, and a threaded column 13 is fixedly connected to the top of the damping spring 12.

[0025] The outer wall of the threaded column 13 is threadedly connected to the inner wall of the threaded groove 10. Due to the threaded connection between the threaded column 13 and the threaded groove 10, the threaded column 13 will increase the resistance through the thread when moving into the threaded groove 10, thereby playing a certain buffering role.

[0026] During use, the base 1 controls the drive mechanism 3 and the hydraulic cylinder body 4 to work. The operation of the drive mechanism 3 and the hydraulic cylinder body 4 can drive the cutter head 5 to process the parts according to the work requirements. When the cutter head 5 vibrates, the bottom damping plate 7 and the top damping plate 6 are subjected to force, which in turn will exert force on the damping column 9 and the threaded column 13. When the threaded column 13 moves into the threaded groove 10, it will increase the resistance through the thread, thereby playing a certain buffering role, which will reduce the vibration force on the damping shock absorber 11. The damping shock absorber 11 can play an effective damping and buffering role when subjected to vibration force. Through multiple damping and buffering effects, the cutter head 5 can play a good buffering function.

[0027] Example 2

[0028] Reference Figure 1-4 In the second embodiment of this utility model, a bearing 14 is fixedly connected to the top of the threaded column 13, and a top mounting block 15 is fixedly connected to the inner ring of the bearing 14. A first mounting channel 16 is opened on the top of the top damping plate 6. The first mounting channel 16 is slidably sleeved with the first expansion bolt 17. The first expansion bolt 17 can be installed and removed through the first mounting channel 16 on the top damping plate 6.

[0029] The bottom of the first expansion bolt 17 extends into the interior of the top mounting block 15, and the first expansion bolt 17 is threadedly connected to the top mounting block 15. When the thread of the first expansion bolt 17 is inside the top mounting block 15, one end of it will expand inside the top mounting block 15, so that the first expansion bolt 17 will not automatically reverse and detach from the top mounting block 15, thereby improving the stability of the installation of the top mounting block 15.

[0030] The bottom of the shock-absorbing column 9 is fixedly connected to the bottom mounting block 8, and the bottom of the bottom shock-absorbing plate 7 is provided with a second mounting channel 18. The second mounting channel 18 is slidably sleeved with the second expansion bolt 19, and the second expansion bolt 19 can be installed and removed through the second mounting channel 18 on the bottom mounting block 8.

[0031] The bottom of the second expansion bolt 19 extends into the interior of the bottom mounting block 8, and the second expansion bolt 19 is threadedly connected to the bottom mounting block 8. When the thread of the second expansion bolt 19 is inside the bottom mounting block 8, one end of it will expand inside the bottom mounting block 8. As a result, the second expansion bolt 19 will not automatically reverse and detach from the bottom mounting block 8, thus improving the stability of the installation of the bottom mounting block 8.

[0032] During use, when the thread of the first expansion bolt 17 is inside the top mounting block 15, one end of it will expand inside the top mounting block 15, thus preventing the first expansion bolt 17 from automatically reversing and disengaging from the top mounting block 15. Similarly, when the thread of the second expansion bolt 19 is inside the bottom mounting block 8, one end of it will expand inside the bottom mounting block 8, thus preventing the second expansion bolt 19 from automatically reversing and disengaging from the bottom mounting block 8. This improves the stability of the installation of the top mounting block 15 and the bottom mounting block 8.
