Description

Technical Field

[0001] The present invention relates to the technical field of multi-station machining centers, and specifically to a multi-station machining center with good stability performance. Background Art

[0002] A multi-station machining center is an advanced numerical control machine tool. It integrates multiple machining products and can complete the machining tasks of multiple stations in one clamping. It has the characteristics of high efficiency, high precision, and high flexibility, and is widely used in modern manufacturing.

[0003] When traditional multi-station machining centers process products, due to the differences in the products to be processed, the machining drills required in the product process are also different. Therefore, it will lead to frequent replacement of the drills, which in turn increases the complexity during the use of the multi-station machining center. Moreover, when a multi-station machining center is in use, generally, in order to ensure the machining effect of multiple stations, two or more machining devices are required. However, the machining positions of the two machining devices are generally set differently. When the output devices at these two different positions are operating, different forces, torques, or motion states may be generated, which causes the overall device to be affected by uneven forces, resulting in unstable phenomena such as position deviation and vibration. Since the machining of the device is unstable, it may lead to a problem of reduced precision of the machined product. In addition, the two machining devices also increase the costs of procurement, installation, and maintenance, thereby increasing the overall cost of the device.

And an anti-slip convex block 5041 for anti-slip is fixed on the conical head of the conical chuck 504;

[0038] On the lower sides of the front and rear sides of the inner wall of the annular disc 501, semi-circular grooves 505 for guiding are provided.

The inner wall of the sleeve 509 is internally embedded and clamped with a drill bit 510 for processing. The embedding of the sleeve 509 and the drill bit 510 can only ensure up and down movement and will not cause the problem of relative rotation between the sleeve 509 and the drill bit 510.

A number of N-shaped extrusion blocks 514 are all rubber blocks with an N-shaped structure, and a number of first T-shaped plates 513 are all plates with a T-shaped structure in a top view.

[0040] The rotating connection assembly 8 includes a square block 801 rotatably connected to the lower side of the inner wall of the processing bottom shell 1, and a special-shaped disk 802 for rotating transmission is fixedly installed on the top surface of the square block 801. The special-shaped disk 802 is composed of a cylinder 8021 and a plurality of arc blocks 8022 fixed on the circumference of the cylinder 8021. The top surface of the cylinder 8021 is fixedly connected to the bottom surface of the fixed disk 9, and the opposite sides of the square block 801 are provided with L-shaped spring plates 803 for elastic limiting, and the bottom surface of the L-shaped spring plate 803 is fixed to the processing bottom shell 1. The lower side of the inner wall is fixedly connected, and the fixation of the L-shaped spring plate 803 and the bottom surface of the processing bottom shell 1 is a point fixation effect, that is, the corners and short sides of the L-shaped spring plate 803 are fixed to the lower side of the inner wall of the processing bottom shell 1, which will not affect the movement of the long side of the L-shaped spring plate 803. The left and right sides of the surface of the support frame 2 are fixedly connected to the top surface of the processing bottom shell 1 through two fixed triangular blocks 13.

[0042] Among them, the placement component 10 includes a rotating gear 1001 rotatably installed on the top surface of the fixed disk 9. The rotation effect between the rotating gear 1001 and the fixed disk 9 will not affect the stability of the placement frame 1002 during the processing. The rotation connection effect between the rotating gear 1001 and the fixed disk 9 is tight, and a certain force is required to rotate, which will not affect the normal processing of the product on the placement frame 1002, and can also ensure that it rotates through the engagement of the tooth block 1105. A placement frame 1002 for placing products is fixedly installed on the top surface of the rotating gear 1001, and the tooth surfaces of several rotating gears 1001 are located on the lower side of the whole arrangement, and several placement frames 1002 are all rectangular troughs made of stainless steel, and a frame structure with holes is opened on the lower side of the inner wall of the rectangular trough. The frame structure of the placement frame 1002 can be more conducive to the export of drilling debris.

[0043] Among them, the auxiliary component 11 includes a second limit shell 1101 fixedly installed on the top surface of the auxiliary connection block 12. The inner wall of the second limit shell 1101 is fixedly installed with a number of tooth blocks 1105 for meshing connection through a sliding second T-plate 1102. One side of the two second T-plates 1102 close to the fixed disk 9 penetrates the inner wall of the second limit shell 1101 and extends to the surface of the second limit shell 1101. The surfaces of a number of corresponding tooth blocks 1105 are meshed with the surface of the rotating gear 1001. On the left and right sides of the surface of the second T-plate 1102, elastic pushing springs 1104 are sleeved through sliding guide rods 1103. The two corresponding springs 1104 are arranged on the side of the rod arm of the guide rod 1103 away from the fixed disk 9. The structures of the second T-plate 1102 and the first T-plate 513 are the same, which can ensure stable movement within the limit shell structure and avoid completely moving out of the limit shell structure.

[0044] The working principle of the above embodiment is as follows:

[0045] During the use of the device, the operator places the product to be processed on the placement frame 1002 to hold it. Then, due to the up and down movement of the electric telescopic rod 3, the product on the placement frame 1002 can be rotated to the lower side of the ring disk 501 for drilling processing. This device mainly performs drilling processing on the product.

[0046] The product under the ring disk 501 is in a waiting processing state. Before drilling the product, the drill bit 510 will be adjusted according to the type of the product. When the drill bit 510 needs to be adjusted, only need to pull the drill bit 510 to make it away from the tapered chuck 504 on the output motor 503. In this way, the drill bit 510 together with the sleeve 509 and the fixing ring 508 can move inside the semi-circular groove 505. Then, move the required drill bit 510 under the tapered chuck 504 and release the hand. Under the pulling force of the damping tension spring 511, the drill bit 510 is clamped with the tapered chuck 504, which is convenient for subsequent drilling operations. The replaced drill bit 510 will contact and press against the inner wall of the ring disk 501 under the pulling force of the damping tension spring 511, so as to ensure that the replaced drill bit 510 can be clamped in the ring disk 501 for standby.

[0047] After the replacement of the drill bit 510 is completed, the processing operation of the product begins. The electric telescopic rod 3 drives the pressing components 5 on both sides of the connecting cross block 4, that is, the drilling structure in the ring plate 501, to drill the product on the placement frame 1002. During the downward pressing process of the ring plate 501, the first T-plate 513 on the first limiting shell 512 drives the N-shaped extrusion block 514 to extrude the product on the placement frame 1002, which can ensure the stability during the product processing. And by driving the pressing components 5 on both the left and right sides to press down simultaneously through the electric telescopic rod 3, it can avoid the problem of the overall shaking caused by uneven pressure on the device, and increase the use stability of the device;

[0048] After the product is drilled once, the electric telescopic rod 3 lifts the pressing component 5. Then, the micro electric telescopic rod 804 pushes the telescopic block 805 to move. The telescopic block 805 pushes the special-shaped disk 802 through the dial block 808 on the connecting groove block 807. Under the elastic extrusion of the arc-shaped elastic piece 809, the dial block 808 can closely fit on the surface of the special-shaped disk 802, and the dial block 808 and the arc-shaped bending block 8022 on the special-shaped disk 802 resist each other, so as to rotate the special-shaped disk 802. The bottom surface of the special-shaped disk 802 is attached to the two L-shaped elastic plates 803 through the square block 801. In this way, under the extrusion of the L-shaped elastic plates 803, when the square block 801 rotates more than 45 degrees, it can rotate under the extrusion force of the L-shaped elastic plates 803. The micro electric telescopic rod 804 drives the dial block 808 to push the special-shaped disk 802 to rotate an angle greater than 45 degrees, which can ensure that after the micro electric telescopic rod 804 pushes the special-shaped disk 802 by a certain angle, when it retracts, it will not affect the effect of the L-shaped elastic plates 803 driving the special-shaped disk 802 to rotate 90 degrees;

[0049] When the special-shaped disk 802 rotates 90 degrees each time, the fixed disk 9 on the special-shaped disk 802 will also rotate 90 degrees. During the rotation of the fixed disk 9, the placement component 10 connected to the top will follow the rotation. When the rotating gear 1001 on the placement component 10 meshes with the tooth block 1105 on the auxiliary component 11, rotation will occur. When the fixed disk 9 drives the placement component 10 past the auxiliary component 11, under the meshing action of several tooth blocks 1105, the placement frame 1002 on the rotating gear 1001 will rotate. Here, the meshing length between the rotating gear 1001 and several tooth blocks 1105 on the second T-plate 1102 can make the placement frame 1002 rotate 90 degrees, so as to ensure that when the left and right pressing components 5 process the product, they can process different positions of the product, thus meeting the processing effect of the product and ensuring the effect of multi-station processing. Moreover, the auxiliary components 11 are arranged in the front and back. In this way, it can be ensured that after the rotation of the first auxiliary component 11, the position relative to the just-placed and processed position will change by 90 degrees. And after passing through the other auxiliary component 11, it will rotate 90 degrees again, so that the product will be rotated to the just-placed position. In this way, it can be ensured that the position of the product under the left and right pressing components 5 is the same each time, but relatively different. The start of the electric telescopic rod 3 and the micro electric telescopic rod 804 of this device is staggered start. This device can use a time relay to set different delay times to achieve the staggered start of the two electrical components. This start method is a mature technology with limited problems. This article highlights the innovative structure and will not elaborate too much on the prior art.

[0050] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can easily realize the control of the electrical components through simple programming, and the existing publicly disclosed power connection technology also belongs to the common knowledge in this field. Therefore, the specific structural composition and working principle will not be elaborated too much in this embodiment.
