[0002] Milling machines mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. Usually, the main motion is the rotation of the milling cutter, and the movement of the workpiece and the milling cutter is the feed motion. It can process planes, grooves, various curved surfaces, gears, etc.

[0003] Some workpieces have fewer processing steps and the processing directions are both vertical and horizontal, so the processing difficulty is not high. In this case, you can choose to process multiple workpieces at the same time to save space and power. However, the milling cutter needs to be replaced frequently during the processing. There are two common methods. One is manual replacement, which is time-consuming and labor-intensive.

[0016] The present invention provides a reciprocating multi-head milling machine. It has the following beneficial effects:

[0017] (1) The reciprocating multi-head milling machine, through the storage and retrieval mechanism, the milling cutter clamping part enters the clamping storage part, the clamping storage part can be elastically extended and retracted, so as to adapt and clamp the milling cutter clamping part, and then the milling cutter head is plugged with the new milling cutter, and the milling cutter and the loading and unloading auxiliary part are squeezed.

The two arc-shaped clamping plates form a "J" shape, which is convenient for the milling cutter head to slide inward along the arc surface of the arc-shaped clamping plate.

DETAILED DESCRIPTION

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0034] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation of the present invention.

[0035] Please refer to Figure 4-9 , the present invention provides a technical solution: a reciprocating multi-head milling machine, including a support plate 1, a moving plate 5 is fixedly connected to the right side of the moving member 3, a milling cutter head 7 is fixedly connected to the right side of the moving plate 5, a workbench 4 is arranged on the side of the moving plate 5 away from the moving member 3, an access mechanism 6 is fixedly connected to the top of the support plate 1, and the access mechanism 6 includes an access integrated device 65;

[0036] The access integrated device 65 includes:

[0037] A milling cutter 653;

[0038] A clamping and storing member 651, which has a telescopic structure. The clamping and storing member 651 can move up and down along the vertical direction under pressure. The clamping and storing member 651 can clamp the milling cutter 653 placed therein. The clamping and storing member 651 includes a guide rail 6511. A chute 6513 is opened on the side of the guide rail 6511 away from the first pneumatic hydraulic pump 66. A slider 6516 is slidably connected to the chute 6513. An arc-shaped clamping plate 6517 is fixedly connected to the side of the slider 6516 away from the guide rail 6511. A friction groove 6518 is opened on the inner side of the arc-shaped clamping plate 6517. A round hole 6519 is opened at the top of the arc-shaped clamping plate 6517. A first spring 6515 is fixedly connected to the top of the slider 6516. The top of the first spring 6515 is fixedly connected to an extension plate 6512. The side of the extension plate 6512 away from the arc-shaped clamping plate 6517 is fixedly connected to the side of the guide rail 6511 close to the arc-shaped clamping plate 6517. Fixing plates 6514 are arranged on both sides of the first spring 6515. The two ends of the fixing plate 6514 are respectively fixedly connected to one side of the guide rail 6511 and the extension plate 6512. The side of the guide rail 6511 close to the first pneumatic hydraulic pump 66 is fixedly connected to the side of the cross plate 62 away from the first pneumatic hydraulic pump 66. There are two arc-shaped clamping plates 6517 on one clamping and storing member 651. The arc-shaped clamping plates 6517 are "S" shaped. The two arc-shaped clamping plates 6517 form a "ji" shape. The clamping part of the two arc-shaped clamping plates 6517 is circular, and the diameter of this circle is smaller than the diameter of the clamping part of the milling cutter 653.

[0039] During use, the milling cutter 653 is sequentially installed in the clamping storage member 651 in the order of use. The arc-shaped clamping plate 6517 is in an "S" shape, and two arc-shaped clamping plates 6517 form a "ji" shape. One side of the two arc-shaped clamping plates 6517 close to the guide rail 6511 is in close contact, and the other side of the two arc-shaped clamping plates 6517 away from the guide rail 6511 is open, facilitating the sliding of the milling cutter head 7 inward along the arc surface of the arc-shaped clamping plate 6517. Especially during manual installation, it can play a guiding and limiting role. The horizontal distance between two adjacent cross plates 62 is the same, and the horizontal distances of the rightmost ends of two adjacent cross plates 62 are the same. Start the moving member 3, and the moving member 3 can drive the moving plate 5 and the milling cutter head 7 to move in the vertical and horizontal directions. The milling cutter head 7 first moves down to the cross plate 62 closest to it. At this time, the milling cutter head 7 is facing the opening between the two arc-shaped clamping plates 6517. Then the milling cutter head 7 moves towards the direction of the arc-shaped clamping plate 6517. The clamping part of the two arc-shaped clamping plates 6517 is circular, but the diameter of this circle is smaller than the diameter of the clamping part of the milling cutter 653. The milling cutter 653 presses against the arc-shaped clamping plate 6517, and the slider 6516 at one end of the arc-shaped clamping plate 6517 can only slide in the chute 6513. Therefore, the milling cutter 653 moves towards the extension plate 6512 along with the slider 6516, and the first spring 6515 is compressed. The inner side of the arc-shaped clamping plate 6517 is provided with a friction groove 6518 to increase the friction force, making it difficult for the milling cutter 653 to fall off from the friction groove 6518. Finally, the milling cutter head 7 is withdrawn, and at this time, the milling cutter head 7 is separated from the milling cutter 653. This structure is simple and can quickly disassemble the milling cutter 653 that needs to be replaced;

[0040] Please refer to Figure 10-11The present invention provides a technical solution: a loading and unloading auxiliary part 652, which has a compression structure, and the loading and unloading auxiliary part 652 squeezes the milling cutter 653, and gives the milling cutter 653 a reaction force after the milling cutter 653 is inserted, and the loading and unloading auxiliary part 652 has a pulley assembly, and the loading and unloading auxiliary part 652 drives the clamping storage part 651, and the milling cutter 653 in the clamping storage part 651 is loosened, and the loading and unloading auxiliary part 652 includes a fixed block 6521, and the side of the fixed block 6521 away from the first pneumatic hydraulic pump 66 is fixedly connected to a round rod 6522, and the side of the round rod 6522 close to the fixed block 6521 is fixedly connected to a fixed pulley 6523, and the fixed pulley 6523 is wound with a traction rope 652 4. One end of the traction rope 6524 close to the moving plate 5 is fixedly connected to the side of the arc-shaped clamping plate 6517 away from the moving plate 5, and the other end of the traction rope 6524 is fixedly connected to the pressing plate 6525, and the side of the pressing plate 6525 away from the moving plate 5 is fixedly connected to the bowl cover plate 6529, and the side of the bowl cover plate 6529 away from the moving plate 5 is fixedly connected to the sliding rod 6526, and the sliding rod 6526 is slidably connected to the limiting cylinder 6527, and the side of the limiting cylinder 6527 away from the moving plate 5 is fixedly connected to the side of the horizontal plate 62 close to the moving plate 5, and the side of the bowl cover plate 6529 away from the moving plate 5 is fixedly connected to the second spring 6528, and one end of the second spring 6528 is fixedly connected to the side of the horizontal plate 62 close to the moving plate 5

[0041] After disassembling the milling cutter 653, a new milling cutter 653 needs to be installed. All cross plates 62 are arranged in an oblique ladder shape. The cross plate 62 where the milling cutter 653 is disassembled and the cross plate 62 where the new milling cutter 653 is installed are adjacent, and the length of the latter cross plate 62 is greater than that of the former, so as to ensure that the disassembled milling cutter 653 will not be touched when the milling cutter 653 is installed. At this time, the milling cutter head 7 moves to a position facing the center of the pressure plate 6525, and the milling cutter head 7 continues to approach the new milling cutter 653 and plug it with it. The milling cutter head 7 continues to push the milling cutter 653 forward, and the milling cutter 653 contacts and squeezes the pressure plate 6525, the bowl cover plate 6529, and the second spring 6528. The shapes of the pressure plate 6525 and the bowl cover plate 6529 can use a variety of shapes of milling cutters 653. , the second spring 6528 is compressed, and the milling cutter 653 is subjected to a reaction force, which facilitates the tighter insertion of the milling cutter 653 and the milling cutter head 7. The bowl cover 6529 slides along the limiting cylinder 6527 with the slide bar 6526. The limiting cylinder 6527 can ensure that the slide bar 6526, the bowl cover 6529, the pressing plate 6525, and the milling cutter 653 move along the axial direction of the limiting cylinder 6527 without tilting in the direction. The pressing plate 6525 pulls the two traction ropes 6524 and the arc-shaped splint 6517 in turn, and the distance between the two arc-shaped splints 6517 continues to increase. At this time, the pressure of the arc-shaped splint 6517 on the milling cutter 653 is reduced or even disappears. At this time, the milling cutter 653 is pulled out from the bowl cover 6529 and the two arc-shaped splints 6517 in turn;
