Description

Technical Field

[0001] The invention relates to the technical field of milling machine tools, in particular to a double-cutter head rotary milling device. Background Art

[0002] Milling machine tools, also known as milling machines for short, are machine tools that use milling cutters to process various surfaces of workpieces. The working principle of a milling machine is to cut the workpiece through a rotating tool, in which the rotation of the tool is the main motion, and the movement of the workpiece and the milling cutter is the feed motion. The milling machine can process planes, grooves, various curved surfaces, gears and other complex shapes, and has a wide range of processing capabilities.

[0003] When a milling machine is performing machining, usually one cutter head processes the workpiece, and some parts need to be milled on both sides at the same time. In this case, the angle of the workpiece needs to be changed many times, which makes the processing more troublesome. In large-scale manufacturing, since the existing milling machine tools cannot perform double-sided processing, the subsequent milling process is inefficient. Improvements need to be made to this problem. Summary of the invention

[0007] According to the above technical solution, the adjustment assembly includes an adjustment frame 1, an adjustment block 1, a telescopic rod, an adjustment block 2, an adjustment frame 2, a rotating shell, a drive motor 2 and a milling cutter head. The adjustment frame 1 is fixedly connected to the front face of the ball nut pair, the adjustment block 1 is rotatably connected to the inner middle part of the adjustment frame 1, the telescopic rod is fixedly connected to the side of the adjustment block 1 away from the adjustment frame 1, the adjustment block 2 is fixedly connected to the end of the telescopic rod away from the adjustment block 1, the adjustment frame 2 is rotatably connected to the inside of the adjustment block 2, the rotating shell is fixedly connected to the side of the adjustment frame 2 away from the adjustment block 2, the drive motor 2 is fixedly connected to the inner middle part of the rotating shell, the drive motor 2 has an output shaft, and the milling cutter head is fixedly connected to the output shaft of the drive motor 2.

[0008] According to the above technical solution, the auxiliary component includes a storage frame, a limiting slide groove and a sliding wheel. The storage frame is fixedly connected to the front of the positioning plate, the limiting slide groove is fixedly connected to the top and bottom of the storage frame, and the sliding wheel is fixedly connected to the top and bottom of the rotating shell.

[0009] According to the above technical solution, the telescopic end of the hydraulic telescopic rod passes through the back side of the driving plate and extends to the front side of the driving plate and is fixedly connected to the back side of the movable plate. Guide slide bars are provided at the top and bottom of the front side of the driving plate. Moving sliding rings corresponding to the guide slide bars are provided in the middle of the top and bottom of the movable plate. The movable plate is slidably connected to the driving plate through the moving sliding ring.

[0010] According to the above technical solution, a circular groove is opened in the positioning plate to accommodate the rotation of the bidirectional threaded rod, the bidirectional threaded rod is built into the circular groove, and an output shaft of the drive motor passes through the outside of the support plate and extends to the inside of the support plate to be fixedly connected to the bidirectional threaded rod.

[0011] According to the above technical solution, the sliding wheel is built into the limiting sliding groove, and the sliding wheel is slidably connected to the inner wall of the limiting sliding groove, and the rotating shell is slidably connected to the limiting sliding groove through the sliding wheel.

[0012] According to the above technical solution, a positioning frame is fixedly connected to the middle of the front side of the storage frame, and the rotating shell is rotatably connected to the middle of the positioning frame.

[0013] According to the above technical scheme, the number of the positioning plate, adjustment frame 1, adjustment block 1, telescopic rod, adjustment block 2, adjustment frame 2, rotating shell, drive motor 2, milling cutter head, storage frame, limiting slide groove and sliding wheel is two, and the two positioning plates, adjustment frame 1, adjustment block 1, telescopic rod, adjustment block 2, adjustment frame 2, rotating shell, drive motor 2, milling cutter head, storage frame, limiting slide groove and sliding wheel are symmetrically distributed on the left and right sides of the front side of the movable plate.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when the workpiece needs to be milled, the present invention controls the second drive motor to work, controls the milling cutter head to rotate when the second drive motor is working, and then starts the hydraulic telescopic rod to make the hydraulic telescopic rod push the moving plate to move, and synchronously makes the milling cutter head on the second drive motor contact the outside of the workpiece, so that the feeding work can be performed when the outside of the workpiece is milled; When the angle of the milling cutter head needs to be adjusted, when the contact angle between the milling cutter head and the workpiece needs to be adjusted smaller, the driving motor 1 is controlled to work, and when the driving motor 1 is working, the bidirectional threaded rod is controlled to rotate, so that the ball nut pair moves from the outside to the middle on the bidirectional threaded rod. At the same time, when the ball nut pair moves, the adjusting frame 1 pushes the adjusting block 1, so that the adjusting block pair squeezes the telescopic rod. At this time, the telescopic rod contracts, and at the same time, the telescopic rod drives the adjusting block 2, so that the adjusting frame 2 squeezes the rotating shell. Since one side of the rotating shell is rotatably connected to the positioning frame on the front side of the storage frame, the rotating shell rotates around the middle of the positioning frame, so that the rotating shell moves to the inside of the storage frame. At this time, the angle when the milling cutter head contacts the workpiece becomes smaller. When the contact angle between the milling cutter head and the workpiece needs to be increased, the driving motor 1 is controlled to work, and the bidirectional threaded rod is controlled to rotate when the driving motor 1 is working, so that the ball nut pair moves from the middle to the outside on the bidirectional threaded rod. At the same time, when the ball nut pair moves, the adjusting frame 1 pulls the adjusting block 1, so that the adjusting block 1 pulls the telescopic rod synchronously. At this time, the telescopic rod stretches, and the telescopic rod drives the adjusting block 2 at the same time, so that the adjusting frame 2 can pull the rotating shell, so that the rotating shell rotates around the middle of the positioning frame, and the rotating shell moves to the outside of the storage frame. At this time, the contact angle between the milling cutter head and the workpiece becomes larger, so that the device can adjust the contact angle between the milling cutter head and the workpiece according to the needs during processing. By setting up two drive motors and a milling cutter head, double-head milling can significantly improve production efficiency in small and medium-sized batch production. Since double-head milling has the ability to process two tools at the same time, the process that originally required multiple cuts can be completed at one time, thereby shortening the production cycle and reducing production costs.

[0023] The auxiliary component 6 includes a storage frame 601, a limiting slide groove 602 and a sliding wheel 603. The storage frame 601 is fixedly connected to the front of the positioning plate 401, the limiting slide groove 602 is fixedly connected to the top and bottom of the storage frame 601, and the sliding wheel 603 is fixedly connected to the top and bottom of the rotating shell 506.

[0024] The sliding wheel 603 is built into the limiting sliding groove 602 , and the sliding wheel 603 is slidably connected to the inner wall of the limiting sliding groove 602 , and the rotating shell 506 is slidably connected to the limiting sliding groove 602 through the sliding wheel 603 .

[0025] A positioning frame is fixedly connected to the middle of the front side of the storage frame 601, and the rotating shell 506 is rotatably connected to the middle of the positioning frame.

[0026] There are two positioning plates 401, adjustment frame 1 501, adjustment block 1 502, telescopic rod 503, adjustment block 2 504, adjustment frame 2 505, rotating shell 506, drive motor 2 507, milling cutter head 508, storage frame 601, limiting slide groove 602 and sliding wheel 603. The two positioning plates 401, adjustment frame 1 501, adjustment block 1 502, telescopic rod 503, adjustment block 2 504, adjustment frame 2 505, rotating shell 506, drive motor 2 507, milling cutter head 508, storage frame 601, limiting slide groove 602 and sliding wheel 603 are symmetrically distributed on the left and right sides of the front side of the movable plate 3.

[0027] When the workpiece needs to be milled, the drive motor 2 507 is controlled to work, and the milling cutter head 508 is controlled to rotate when the drive motor 2 507 is working. Then, the hydraulic telescopic rod 2 is started to make the hydraulic telescopic rod 2 push the movable plate 3 to move, and the milling cutter head 508 on the drive motor 2 507 is synchronously made to contact the outside of the workpiece, so that the feeding work can be performed when milling the outside of the workpiece.

[0028] When the angle of the milling cutter head 508 needs to be adjusted, when the contact angle of the milling cutter head 508 with the workpiece needs to be adjusted, the drive motor 403 is controlled to work. When the drive motor 403 is working, the bidirectional threaded rod 404 is controlled to rotate, so that the ball nut pair 405 moves from the outside to the middle on the bidirectional threaded rod 404. At the same time, when the ball nut pair 405 moves, the adjustment frame 501 pushes the adjustment block 502, so that the adjustment block 502 squeezes the telescopic rod 503.

At this time, the angle when the milling cutter head 508 contacts the workpiece becomes smaller.

[0029] When it is necessary to increase the contact angle between the milling cutter head 508 and the workpiece, the driving motor 403 is controlled to work. When the driving motor 403 is working, the bidirectional threaded rod 404 is controlled to rotate, so that the ball nut pair 405 moves from the middle to the outside on the bidirectional threaded rod 404. At the same time, when the ball nut pair 405 moves, the adjusting frame 501 pulls the adjusting block 502, so that the adjusting block 502 synchronously pulls the telescopic rod 503. At this time, the telescopic rod 503 is stretched, and the telescopic rod 503 drives the adjusting block 2 504, so that the adjusting frame 2 505 can pull the rotating shell 506, so that the rotating shell 506 rotates around the middle of the positioning frame, and the rotating shell 506 moves to the outside of the storage frame 601. At this time, the contact angle between the milling cutter head 508 and the workpiece becomes larger, so that the device can adjust the contact angle between the milling cutter head 508 and the workpiece according to the needs during processing.

[0030] By setting two drive motors 507 and a milling cutter head 508, double-head milling can significantly improve production efficiency in small and medium-sized batch production. Since double-head milling has the ability to process with two tools at the same time, the process that originally required multiple cuts can be completed at one time, thereby shortening the production cycle and reducing production costs.
