Description

Technical Field

[0001] This utility model relates to the field of milling device technology, and in particular to a milling device for shaft machining. Background Technology

[0002] The milling device is used to machine grooves on the surface of a shaft. The milling device consists of a worktable, a slide, a drive motor, a drive rod, a milling cutter, an electric cylinder, a mounting frame, and a pressure table. When using the milling device, the worker places the shaft in the slide groove, then starts the first electric cylinder on the mounting frame to press down the pressure table, and then starts the second electric cylinder to move the slide back and forth. At the same time, the drive motor is started to rotate the drive rod, which in turn rotates the milling cutter, thereby machining grooves on the surface of the shaft.

[0003] In their daily work, the inventors discovered that when using the milling device, it is sometimes necessary to machine multiple sets of grooves on the shaft. However, some milling devices lack a shaft adjustment mechanism, which means that the shaft position can only be adjusted manually and then fixed by a pressure table before milling. This may increase the workload of workers and affect the efficiency of milling. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in actual use, it is sometimes necessary to process multiple sets of grooves on a shaft. However, some milling devices lack a shaft adjustment mechanism, which means that the shaft position can only be adjusted manually and then fixed by a pressure table before milling. This may increase the workload of workers and affect the efficiency of milling. Therefore, this invention proposes a milling device for shaft processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a milling device for machining shafts, comprising a worktable, a drive motor mounted on one side of the worktable, a drive rod provided on one side of the worktable, the drive motor controlling the rotation of the drive rod, a milling cutter provided at one end of the drive rod, a slide table slidably connected to the upper end of the worktable, a mounting frame fixedly connected to the upper end of the slide table, a first electric cylinder mounted on the upper end of the mounting frame, a pressure table provided at the lower end of the mounting frame, the pressure table and the first electric cylinder being fixed, a second electric cylinder mounted on the back of the worktable, the second electric cylinder and the slide table being fixed, an adjustment assembly provided at the upper end of the slide table, the adjustment assembly comprising a fixed ring fixedly connected to the upper end of the slide table, an adjustment ring rotatably connected to the front of the fixed ring by means of a bearing, a pushing mechanism provided on the arc surface of the adjustment ring, a clamping block provided on the inner arc surface of the adjustment ring, and a driving mechanism provided at the lower end of the adjustment ring, the driving mechanism being used to drive the adjustment ring to rotate, and the pushing mechanism being used to push the clamping block.

[0006] The effect achieved by the above components is as follows: by setting the adjustment component, when the shaft needs to be rotated, before milling the groove on the shaft, the clamping block is first pressed onto the surface of the shaft by the pushing mechanism for fixation. After milling the groove on one side of the shaft, the adjustment ring is rotated by the driving mechanism, thereby causing the shaft to rotate. Then the groove is milled again, thereby reducing the workload of workers and improving the efficiency of milling.

[0007] Preferably, the pushing mechanism includes a plurality of evenly distributed push rods slidably inserted into the arc surface of the adjusting ring, the push rods and the clamping block are fixed, and the arc surface of the adjusting ring is threadedly connected to a threaded ring.

[0008] The effect achieved by the above components is as follows: the worker manually screws the threaded ring, causing the threaded ring to move forward, which pushes the push rod, causing the clamping block to be pushed and pressed against the surface of the shaft for fixation.

[0009] Preferably, a first spring is fixedly connected to the arc surface of the clamping block, and the other end of the first spring is fixed to the adjusting ring.

[0010] The effect achieved by the above components is as follows: the worker manually tightens the threaded ring to release the pressure of the threaded ring on the push rod, so that the first spring returns to its original position, the clamping block moves away from the shaft, and the limitation on the shaft is released.

[0011] Preferably, the driving mechanism includes a toothed ring fixedly connected to the arc surface of the adjusting ring, and the arc surface of the toothed ring is meshed with a gear.

[0012] The effect achieved by the above components is that the gear rotates, causing the gear ring to rotate, which in turn causes the adjusting ring to rotate.

[0013] Preferably, a mounting rod is fixedly connected to the front of the slide, and a stepper motor is mounted on one side of the mounting rod, the stepper motor controlling the rotation of the gear.

[0014] The aforementioned components achieve the following effects: the stepper motor on the starting mounting rod is fixed to the gear ring via a reducer and coupling, causing the gear to rotate; the stepper motor has a self-locking function.

[0015] Preferably, a pre-fixing component is provided between the milling cutter and the drive rod, the pre-fixing component being used to pre-fix the drive rod to the milling cutter.

[0016] The effect achieved by the above components is that, by setting the pre-fixing component, when installing the milling cutter onto the drive rod, the milling cutter is first pre-fixed by the pre-fixing component, and then fixed with screws.

[0017] Preferably, the pre-fixing component includes a trapezoidal block slidably inserted into the inner wall of the drive rod, the trapezoidal block being inserted into the milling cutter, and a second spring being fixedly connected between the trapezoidal block and the drive rod.

[0018] The effect achieved by the above components is as follows: dragging the milling cutter causes it to be inserted into the drive rod, causing the trapezoidal block to be squeezed back into the drive rod, compressing the second spring. After the milling cutter is fully inserted into the drive rod, the second spring returns to its original position, allowing the trapezoidal block to be inserted into the milling cutter, thereby pre-fixing the milling cutter.

[0019] Preferably, a pull rope is fixedly connected to the right end of the trapezoidal block, and the pull rope passes through the drive rod.

[0020] The effect achieved by the above components is: pulling the pull rope causes the trapezoidal block to retract into the drive rod, thus dragging the milling cutter for dismantling.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting an adjustment component, when the shaft needs to be rotated, before milling the groove on the shaft, the clamping block is first pressed onto the surface of the shaft by a pushing mechanism for fixation. After milling the groove on one side of the shaft, the adjusting ring is rotated by a driving mechanism, thereby rotating the shaft. Then, the groove is milled again, thus minimizing the workload of workers and improving the efficiency of milling. This solves the problem that sometimes multiple grooves need to be machined on the shaft, but some milling devices lack a shaft adjustment mechanism, which means that the shaft position can only be manually adjusted and then fixed by a pressure table before milling, which may increase the workload of workers and affect the efficiency of milling.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a milling device for shaft machining includes a worktable 1, a drive motor 5 installed on one side of the worktable 1, a drive rod 6 provided on one side of the worktable 1, the drive motor 5 controls the rotation of the drive rod 6, a milling cutter 7 is provided at one end of the drive rod 6, a slide table 4 is slidably connected to the upper end of the worktable 1, a mounting frame 8 is fixedly connected to the upper end of the slide table 4, a first electric cylinder 9 is installed at the upper end of the mounting frame 8, a pressure table 10 is provided at the lower end of the mounting frame 8, the pressure table 10 and the first electric cylinder 9 are fixed, a second electric cylinder 11 is installed on the back of the worktable 1, the second electric cylinder 11 and the slide table 4 are fixed, and an adjustment component 2 is provided at the upper end of the slide table 4.

[0030] Reference Figure 2 and Figure 3As shown, in this embodiment: the adjusting assembly 2 includes a fixed ring 21 fixedly connected to the upper end of the slide table 4. An adjusting ring 22 is rotatably connected to the front of the fixed ring 21 via a bearing. A pushing mechanism 24 is provided on the arc surface of the adjusting ring 22, and a clamping block 23 is provided on the inner arc surface of the adjusting ring 22. A driving mechanism 25 is provided at the lower end of the adjusting ring 22. The driving mechanism 25 is used to drive the adjusting ring 22 to rotate, and the pushing mechanism 24 is used to push the clamping block 23. By setting the adjusting assembly 2, when it is necessary to rotate the shaft, before milling the groove on the shaft, first... By pushing mechanism 24, clamping block 23 is pressed against the surface of shaft for fixation. After milling grooves on one side of shaft, driving mechanism 25 causes adjusting ring 22 to rotate, thereby rotating shaft. Then, groove is milled again, thus minimizing worker workload and improving milling efficiency. Pushing mechanism 24 includes multiple evenly distributed push rods 241 slidably inserted into the arc surface of adjusting ring 22. Push rods 241 and clamping block 23 are fixed. Threaded ring 243 is threadedly connected to the arc surface of adjusting ring 22. Worker manually tightens threaded ring 243. This causes the threaded ring 243 to move forward, pushing the push rod 241 and causing the clamping block 23 to be pushed against the shaft surface for fixation. A first spring 242 is fixedly connected to the arc surface of the clamping block 23, and the other end of the first spring 242 is fixed to the adjusting ring 22. The worker manually tightens the threaded ring 243 to release the pressure of the threaded ring 243 on the push rod 241, causing the first spring 242 to reset, and the clamping block 23 to move away from the shaft, thus releasing the limitation on the shaft. The drive mechanism 25 includes components fixedly connected to the arc surface of the adjusting ring 22. The gear ring 254 has a gear 253 meshing with its arc surface. When the gear 253 rotates, the gear ring 254 rotates, which in turn causes the adjusting ring 22 to rotate. The front of the slide table 4 is fixedly connected to the mounting rod 251. A stepper motor 252 is mounted on one side of the mounting rod 251. The stepper motor 252 controls the rotation of the gear 253. When the stepper motor 252 on the mounting rod 251 is started, it is fixed to the gear ring 254 through a reducer and a coupling, causing the gear 253 to rotate. The stepper motor 252 has a self-locking function.

[0031] Reference Figure 4As shown in this embodiment: a pre-fixing component 3 is provided between the milling cutter 7 and the drive rod 6. The pre-fixing component 3 is used to pre-fix the drive rod 6 to the milling cutter 7. By providing the pre-fixing component 3, when installing the milling cutter 7 onto the drive rod 6, the milling cutter 7 is first pre-fixed by the pre-fixing component 3, and then fixed with screws. The pre-fixing component 3 includes a trapezoidal block 31 that is slidably inserted into the inner wall of the drive rod 6. The trapezoidal block 31 is inserted into the milling cutter 7, and a second [unclear] is fixedly connected between the trapezoidal block 31 and the drive rod 6. Spring 32 drags the milling cutter 7, causing it to insert into the drive rod 6. This causes the trapezoidal block 31 to be pushed back into the drive rod 6, compressing the second spring 32. After the milling cutter 7 is fully inserted into the drive rod 6, the second spring 32 returns to its original position, allowing the trapezoidal block 31 to be inserted into the milling cutter 7, thus pre-fixing the milling cutter 7. A pull rope 33 is fixedly connected to the right end of the trapezoidal block 31. The pull rope 33 passes through the drive rod 6. Pulling the pull rope 33 causes the trapezoidal block 31 to retract into the drive rod 6, dragging the milling cutter 7 for removal.

[0032] Working principle:

[0033] When using the milling device, the worker places the shaft in the groove of the slide table 4, then activates the first electric cylinder 9 on the mounting bracket 8 to press down the pressure table 10. Next, the second electric cylinder 11 is activated, causing the slide table 4 to move back and forth. Simultaneously, the drive motor 5 (CH / CV model optional) is activated, causing the drive rod 6 to rotate, which in turn rotates the milling cutter 7, thus machining a groove on the shaft surface. Before milling the shaft groove, the worker manually tightens the threaded ring 243, causing it to move forward and push the push rod 241, which in turn pushes the clamping block 23 to the shaft surface for fixation. After milling one side of the shaft, the stepper motor 252 on the mounting rod 251 is activated. The stepper motor 252 is fixed to the gear ring 254 via a reducer and coupling, causing the gear 253 to rotate, which in turn rotates the gear ring 254, allowing the adjustment... The joint ring 22 rotates, thereby causing the shaft to rotate, and then the groove is milled again, thereby reducing the amount of labor for workers and improving the efficiency of milling. The worker manually tightens the threaded ring 243 to release the pressure of the threaded ring 243 on the push rod 241, causing the first spring 242 to return to its original position, causing the clamping block 23 to move away from the shaft, and releasing the limitation on the shaft. The stepper motor 252 (model 28BYG50-18A can be selected) has a self-locking function. Dragging the milling cutter 7, it is inserted into the drive rod 6, causing the trapezoidal block 31 to be squeezed back into the drive rod 6, causing the second spring 32 to be compressed. After the milling cutter 7 is fully inserted into the drive rod 6, the second spring 32 returns to its original position, causing the trapezoidal block 31 to be inserted into the milling cutter 7, thereby pre-fixing the milling cutter 7. Then, it is fixed with screws. Pulling the pull rope 33 causes the trapezoidal block 31 to retract into the drive rod 6, and the milling cutter 7 is dragged to remove it.
