Description

Technical Field

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

[0002] A milling cutter is a key tool used in milling operations. It has one or more sharp cutting teeth that achieve precise cutting of material through rotation. When performing fine machining operations such as grinding, a specialized milling cutter clamping device must be used to stabilize the milling cutter to ensure the accuracy and safety of the machining process, thus facilitating the next step of finishing.

[0003] A clamping device for milling cutter processing, disclosed in CN214393236U, includes a base plate, a rotating mechanism on the upper surface of the base plate, two clamping mechanisms above the rotating mechanism, the two clamping mechanisms being symmetrically arranged, two replacement mechanisms being arranged between the two clamping mechanisms, the two replacement mechanisms being symmetrically arranged, and a milling cutter being arranged on the side of the two replacement mechanisms that are close to each other.

[0004] The above-mentioned device can change the angle of the milling cutter through a rotating mechanism. However, when replacing the clamping plate of the milling cutter, the worker needs to loosen the bolts to disassemble and install it. The process is troublesome and the bolt tightening is also quite laborious, making it inconvenient to replace the clamping plate of the milling cutter. In addition, when moving the clamping plate to position the milling cutter, it is necessary to operate the clamping mechanism on one side one by one. This operation is not only troublesome, but may also cause the milling cutter to be out of the center of the circular plate, which will seriously affect the subsequent milling cutter processing. Utility Model Content

A hand-held turntable is positioned above the first slots. A bidirectional lead screw is fixedly connected to the bottom surface of the hand-held turntable. The bidirectional lead screw passes through the support turntable and the two first slots sequentially and extends to the bottom of the support turntable. The outer surface of the bidirectional lead screw is rotatably connected to the support turntable. A slider is slidably connected inside each of the two first slots. Both sliders are threadedly connected to the bidirectional lead screw. A connecting seat is fixedly connected to the right side of each slider. A second slot is formed on the inner wall of each connecting seat. An insertion block is slidably connected to the inner wall of each of the two second slots. A milling cutter clamping plate is fixedly connected to the side of each insertion block that is close to each other. A self-locking mechanism is provided inside each of the two connecting seats, and the self-locking mechanism includes a limiting tongue.

[0008] Preferably, a third slot is provided on the front of both insertion blocks, and a fourth slot is provided inside both connecting seats.

[0009] Preferably, the outer surface of the limiting tongue is slidably connected to the third slot and the fourth slot respectively, a slide rod is fixedly connected to the front of the limiting tongue, the outer surface of the slide rod is slidably connected to the connecting seat, a spring is sleeved on the outer surface of the slide rod, and the spring is fixedly connected to the inner sidewall of the fourth slot and the limiting tongue respectively.

[0010] Preferably, each of the two connecting seats is provided with a handle on its front side, and the front end of each slide rod is fixedly connected to the handle.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A clamping device for milling cutter machining includes a support turntable 1. Two first slots 2 are formed on the right side of the support turntable 1. A hand turntable 3 is arranged above the first slots 2. A bidirectional lead screw 18 is fixedly connected to the bottom surface of the hand turntable 3. The bidirectional lead screw 18 passes through the support turntable 1 and the two first slots 2 in sequence and extends to the bottom of the support turntable 1. The outer surface of the bidirectional lead screw 18 is rotatably connected to the support turntable 1. By using the hand turntable 3, the operator can easily turn the bidirectional lead screw 18. A slider 4 is slidably connected inside each of the two first slots 2. Both sliders 4 are threadedly connected to the bidirectional lead screw 18. The outer surface of the bidirectional lead screw 18 has symmetrical threads, so that when the bidirectional lead screw 18 rotates, the two sliders 4 can move in a direction away from or close to each other.

[0024] Both sliders 4 are fixedly connected to the right side of the connecting seat 5. The inner wall of both connecting seats 5 is provided with a second slot 8. The inner wall of both second slots 8 is slidably connected to the insert block 7. The side of the two insert blocks 7 that are close to each other is fixedly connected to the milling cutter clamping plate 6. The two sides of the side of the insert block 7 that is away from the milling cutter clamping plate 6 are provided with arc chamfers.

[0025] Both connecting seats 5 are equipped with a self-locking mechanism 9. Both insert blocks 7 have a third slot 10 on their front sides and a fourth slot 11 inside the two connecting seats 5. The self-locking mechanism 9 includes a limiting tongue 903. The outer surface of the limiting tongue 903 is slidably connected to the third slot 10 and the fourth slot 11 respectively. The width of the limiting tongue 903 is adapted to the third slot 10 and the fourth slot 11 respectively, so that the limiting tongue 903 can limit the third slot 10, thereby limiting the insert block 7. The arc-shaped chamfer on the outer surface of the insert block 7 can push the limiting tongue 903 to move.

[0026] A slide rod 901 is fixedly connected to the front of the limiting tongue 903. The outer surface of the slide rod 901 is slidably connected to the connecting seat 5. A spring 902 is sleeved on the outer surface of the slide rod 901. The spring 902 is fixedly connected to the inner side wall of the fourth slot 11 and the limiting tongue 903 respectively. By using the elastic force of the spring 902, the limited tongue 903 that has been pushed open can be driven to reset, so that the limiting tongue 903 can be inserted into the interior of the third slot 10 to limit the insertion block 7.

[0027] Both connecting seats 5 are provided with handles 12 on the front. The front end of each slide rod 901 is fixedly connected to the handle 12. The handles 12 make it convenient for workers to pull the slide rod 901 and the limiting tongue 903 so that the limiting tongue 903 releases the limiting of the third slot 10, thereby making it convenient to disassemble and assemble the milling cutter clamp 6.

[0028] A support plate 13 is provided on the left side of the support turntable 1. A drive motor 14 is installed on the left side of the support plate 13. A drive shaft 15 is fixedly connected to the output end of the drive motor 14. The outer surface of the drive shaft 15 is rotatably connected to the support plate 13. The right end of the drive shaft 15 is fixedly connected to the support turntable 1. By starting the drive motor 14, the drive shaft 15 and the support turntable 1 can be driven to rotate, which can rotate the milling cutter and facilitate the milling cutter processing.

[0029] A connecting chamber 16 is installed on the left side of the support plate 13. The opening on the connecting chamber 16 can be connected to a suitable position on the milling cutter processing equipment through a connector. Two sets of ventilation openings 17 are provided on the outer surface of the connecting chamber 16. The ventilation openings 17 can dissipate the heat generated by the drive motor 14 when it is working, reducing the failure rate caused by overheating.

[0030] Working principle: When the milling cutter needs to be replaced, pulling the handle 12 forward will cause the slide bar 901 and the limiting tongue 903 to release the limiting of the third slot 10, allowing the milling cutter clamp 6 and the insertion block 7 to be removed. Then, the insertion block 7 on the new milling cutter clamp 6 is inserted into the second slot 8. The insertion block 7 can push the limiting tongue 903. When the third slot 10 is aligned with the limiting tongue 903, the spring force of the spring 902 can drive the limiting tongue 903 to reset and insert into the third slot 10, thus realizing the replacement of the milling cutter clamp 6. By rotating the hand dial 3, the bidirectional lead screw 18 can be rotated, which can drive the two sliders 4, the connecting seat 5 and the milling cutter clamp 6 to move closer to each other. This can realize the synchronous limiting of the milling cutter from both sides, so that the milling cutter can be limited to the center of the support turntable 1, which is convenient for subsequent milling.
