Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a processing head mechanism and a processing center. Background Art

[0002] Some machining centers achieve five-axis machining through a swing head. When the swing head of the five-axis machining center swings and rotates, one end of the pipeline will rotate with the rotation of the swing head, and the other end of the pipeline away from the swing head is fixed and will not rotate with the rotation of the swing head. Therefore, the pipeline will become entangled and twisted, resulting in problems such as breakage of the internal reinforcing wire mesh of the pipeline and looseness of the joints.

[0003] For example, in the patent authorization announcement number CN 115365840 B, it is disclosed that the buffer part 5, the guide shaft assembly 6 and the pipeline clamp 7 are arranged at the other end away from the AC swing head corresponding to the slide; wherein the AC swing head activity drives the pipeline movement, the buffer part is used to adjust the length of each pipeline on the slide, the guide shaft assembly 6 is used to drive various pipelines to rotate, and the pipeline clamp is used to cooperate with the branching clamp to classify and fix various pipelines.

[0004] However, in the above patent, the other end of the pipeline is still fixedly connected to the slide, and only a section close to the top of the pipeline is rotated through the pipeline clamp 7 and the guide shaft assembly. The bottom and middle sections of the pipeline can rotate relative to the slide, and the other end of the pipeline is still fixed. The pipeline as a whole cannot rotate as the AC swing head rotates.

[0005] Therefore, how to make the pipeline connection plate move along with the swing of the swing head assembly to ensure that the pipeline can flexibly move accordingly when the swing head assembly rotates is an urgent problem to be solved. Utility Model Content

The accompanying drawings of the specification illustrate examples of embodiments of the utility model, wherein the same reference numerals represent the same elements. It is understood that the scales shown in the accompanying drawings of the specification are not the scales of the actual implementation of the utility model, which are only for the purpose of illustration and are not drawn according to the original size.

[0039] Please see Figure 2 The utility model provides a processing head mechanism, which includes a slide 100 and a swing head assembly 200 rotatably arranged at the lower end of the slide 100.

[0040] Please see Figure 2-6 The ram 100 has an inner cavity 101 extending in height, and an opening is provided on the top side of the inner cavity 101; a connecting pipeline 300 connected to the swing head assembly 200 is provided in the inner cavity 101.

[0041] Please see Figure 2 and 6The swing head assembly 200 includes a U-shaped bracket and a main shaft installed in the U-shaped bracket, and the main shaft can rotate relative to the ram 100 together with the U-shaped bracket, so as to realize the rotation of the main shaft around the C axis. In some other embodiments, the main shaft can rotate relative to the U-shaped bracket around the B axis or the A axis.

[0042] Please see Figure 3 and 4 A pipeline connection plate 400 and a fixed connector 500 are provided at the upper end of the slide 100, wherein the pipeline connection plate 400 is used to support the high position of the connecting pipeline 300, and the fixed connector 500 is connected and communicated with one end of the pipeline away from the swing head assembly 200.

[0043] Please see Figure 4 and 5 , the pipeline connection plate 400 is rotatably arranged at the upper end, for example, the pipeline connection plate 400 only supports rotation within a preset angle range relative to the upper end, the preset angle range can be 0-360°, and is located at the opening position. The connection redundancy between the connecting pipeline 300 from the upper end of the ram to the swing head assembly 200 in the utility model can be set shorter than the traditional pipeline, avoiding the problem of the traditional need to set a longer connecting pipeline 300 to adapt to the swing of the swing head assembly 200, and the longer connecting pipeline 300 causing the inner cavity of the ram 100 to scratch the wall and damage the pipeline.

[0044] The pipeline connection plate 400 is in a disk shape and is horizontally arranged on the ram 100. The pipeline connection plate 400 is provided with a fixing portion 410 corresponding to each of the connecting pipelines 300, and the fixing portion 410 has a through hole 411 matching the cross section of the corresponding connecting pipeline 300, and each of the connecting pipelines 300 is passed through the corresponding through hole 411.

[0045] Please see Figure 4 and 5 , combined with Figure 6 The connecting pipeline 300 will naturally fall down in the through hole 411 due to the action of gravity, so that the gravity of the connecting pipeline 300 is all applied to the fixed connector 500. In order to prevent the gravity of the connecting pipeline 300 from being all applied to the fixed connector 500, causing the fixed connector 500 to bear too much gravity, in this embodiment, a limiter 1400 is provided on the periphery of each connecting pipeline 300. The limiter 1400 is fixedly arranged on the outer periphery of the connecting pipeline 300. The connecting pipeline 300 is limited and matched with the fixing part 410 through the limiter 1400. The limiter 1400 is abutted against the peripheral wall of the through hole 411 formed on the fixing part 410, so as to support the gravity of the connecting pipeline 300 and limit the connecting pipeline 300 from falling relative to the fixing part 410 through the through hole 411.

[0046] Please see Figure 4 and 5 , the stopper 1400 is detachably mounted on the outer periphery of the connecting pipeline 300. For example, the stopper 1400 includes a first fastening member 1410 and a second fastening member 1420, and the first fastening member 1410 and the second fastening member 1420 are detachably sleeved on the outer periphery of the connecting pipeline 300. The first fastening member 1410 and the second fastening member 1420 can be arc-shaped, one end of the first fastening member 1410 and the second fastening member 1420 can be hinged, and the other end of the first fastening member 1410 and the second fastening member 1420 can be detachably connected by bolts, so as to facilitate the first fastening member 1410 and the second fastening member 1420 to be quickly fastened. In some other embodiments, both ends of the first fastening member 1410 and the second fastening member 1420 are detachably connected by bolts, so as to ensure the stability of the installation of the first fastening member 1410 and the second fastening member 1420.

[0047] Please see Figure 3 , 6 And 7, the fixed connection member 500 includes a connection end 501 connected to the corresponding connection pipeline 300, and the connection pipeline 300 is rotatably connected to the connection end 501. By setting the connection end 501, each connection pipeline 300 is rotated by a certain angle along the swing of the swing head assembly 200, so that the single connection pipeline 300 itself is not twisted. Compared with the structural form in which only one end of the connection pipeline 300 rotates and the other end is fixed, the utility model can avoid the risk of the connection pipeline 300 breaking.

[0048] Please see Figure 7The fixed connection member 500 includes a locking portion 510, a bearing portion 520, a rotating portion 530 and a sealing portion 540, and the connecting end 501 is arranged on the locking portion 510; the locking portion 510 and the rotating portion 530 are both cylindrical, and the locking portion 510 is sleeved on the outer periphery of the rotating portion 530 through the bearing portion 520 and the sealing portion 540. One of the locking portion 510 and the rotating portion 530 is connected to the connecting pipeline 300, and the other is fixed relative to the ram 100; the bearing portion 520 is arranged between the locking portion 510 and the rotating portion 530, and the locking portion 510 and the rotating portion 530 can rotate relative to each other through the bearing portion 520, so that the connecting pipeline 300 can rotate relative to the ram 100 through the locking portion 510 and the rotating portion 530 to prevent the connecting pipeline 300 from being entangled; the sealing portion 540 is arranged between the locking portion 510 and the rotating portion 530, and the locking portion 510 and the rotating portion 530 can rotate relative to each other. The seal is maintained by the sealing portion 540, thereby preventing leakage of liquid or gas in the connecting pipeline 300; and / or the fixed connecting component 500 includes an input port 550 and at least two output ports 560, the input port 550 is connected to each output port 560, the number of the connecting pipelines 300 corresponds to the number of the output ports 560, each connecting pipeline 300 is connected to the corresponding output port 560, and at least two connecting pipelines 300 are connected to an external hydraulic source or gas source through a fixed connecting component 500, thereby saving the number of input ports 550 and hydraulic sources or gas sources.

[0049] Please see Figure 4 and 5 , when the corresponding connecting pipeline 300 is pulled by the swing head assembly 200, the pipeline connecting plate 400 can rotate relative to the ram 100 following the connecting pipeline 300; a hollow portion 412 is provided on the fixing portion 410, and each through hole 411 is evenly distributed around the hollow portion 412; a separator 600 is also set on the hollow portion 412, and the separator 600 is used to separate the hollow portion 412 into at least two hollow holes. In this embodiment, the separator 600 is T-shaped, and several pipelines 300 are separated by the separator 600, so as to avoid entanglement between adjacent pipelines 300. It can be understood that the hollow holes are used to separate different types of connecting pipelines 300, and the connecting pipelines 300 in two adjacent hollow holes have different functions. For example, the connecting pipeline 300 is a plurality of wires, and the plurality of wires pass through a hollow hole together. For another example, the connecting pipeline 300 is a plurality of oil pipes, and the plurality of oil pipes pass through a hollow hole. For another example, the connecting pipeline 300 is a plurality of coolant pipes, and the plurality of coolant pipes pass through a hollow hole.

[0050] Please see Figure 4 and 5, the pipeline connection plate 400 can rotate relative to the ram 100 following the swing head assembly 200. For example, the processing head mechanism further includes a bearing 700, the bearing 700 is disposed at the upper end of the ram 100, the fixing portion 410 is rotatably connected to the ram 100 through the bearing 700, and the rotation axis of the bearing 700 is parallel to the extension direction of the ram 100. By providing the bearing 700, the fixing portion 410 on which the connecting pipeline 300 is installed can rotate relative to the ram 100, and the connecting pipeline 300 itself can rotate relative to the fixing portion 410, so that the connecting pipeline 300 can be flexibly rotated relative to the ram 100. In this way, when the main shaft in the swing head assembly 200 swings, the corresponding pipeline on the swing head assembly 200 pulls the first end of the connecting pipeline 300, and the other end of the connecting pipeline 300 moves along with the swing of the swing head assembly 200. At this time, the pipeline connecting plate 400 can rotate along with the swing of the swing head assembly 200. Compared with the original structure in which the connecting pipeline and the slide are fixed, the rotatable pipeline connecting plate 400 can provide a length margin of the connecting pipeline 300 for the swing head assembly 200 to pull, thereby supporting the connecting pipeline 300 to be set shorter.

[0051] Please see Figure 2 The processing head mechanism further includes a drag chain bracket 800 and a drag chain 900. The drag chain bracket 800 is located above the ram 100. The bottom of the drag chain bracket 800 is provided with a first mounting portion 810 for mounting the pipeline connection plate 400, and the top of the drag chain bracket 800 is provided with a second mounting portion 820 for mounting the fixed connector 500. In this embodiment, the cross-sectional area of ​​the drag chain bracket 800 along the horizontal direction is greater than the cross-sectional area of ​​the ram 100 along the horizontal direction, so that the drag chain bracket 800 can carry more structural parts.

[0052] Please see Figure 2 The drag chain 900 is connected to the drag chain bracket 800. The drag chain 900 extends or retracts as the drag chain bracket 800 moves. One end of the drag chain 900 is a crossbeam fixing end 910, and the other end of the drag chain 900 is a drag chain bracket fixing end 920. The drag chain 900 is used to support the connecting pipeline. By setting the drag chain 900, when the ram 100 moves up and down relative to the saddle 1200 and the ram 100 moves left and right relative to the crossbeam 1300, the connecting pipeline connected to the ram 100 and the crossbeam 1300 can freely extend and retract.

[0053] Please see Figure 2 and 6The processing head mechanism also includes a balancing cylinder bracket 1000 and a saddle 1200. The balancing cylinder bracket 1000 is vertically arranged between the drag chain bracket 800 and the slide 100. The balancing cylinder bracket 1000 is used to install the balancing cylinder 1100. The bottom of the balancing cylinder bracket 1000 is connected to the slide 100, and the top of the balancing cylinder bracket 1000 is connected to the drag chain bracket 800. The size of the bottom of the balancing cylinder bracket 1000 is smaller than the size of the top of the balancing cylinder bracket 1000.

[0054] Please see Figure 2 The ram 100 is vertically slidably arranged on the saddle 1200, the number of the balancing cylinders 1100 is an even number, and the even number of the balancing cylinders 1100 are respectively arranged on both sides of the ram 100; each of the balancing cylinders 1100 includes a mounting seat 1110 and a telescopic portion 1120, one of the mounting seat 1110 and the telescopic portion 1120 is connected to the ram 100, and the other of the mounting seat 1110 and the telescopic portion 1120 is connected to the saddle 1200. By providing the balancing cylinders 1100, when the ram 100 moves in the vertical direction relative to the saddle 1200 in the vertical direction, the balancing cylinders 1100 can support the ram 100 and the structural parts installed on the ram 100, so that the screw assembly that drives the ram 100 to move up and down can reduce the load and improve the acceleration of the ram 100 moving up and down.

[0055] When the processing head mechanism is in use, when the swing head assembly 200 rotates relative to the slide 100, since the swing head assembly 200 is connected to the connecting pipeline 300, one end of the connecting pipeline 300 will also rotate, and the middle and upper part of the connecting pipeline 300 can rotate relative to the fixed part 410 through the through hole 411 of the fixed part 410, and the fixed part 410 can rotate relative to the slide 100, so that the middle and upper part of the connecting pipeline 300 can also rotate relative to the slide 100 through the fixed part 410, and the end of the connecting pipeline 300 away from the swing head assembly 200 is rotatably connected to the fixed connector 500, so that the connecting pipeline 300 can rotate with the rotation of the swing head assembly 200, thereby ensuring the safety of the connecting pipeline 300 when the swing head assembly 200 rotates.

[0056] The above-mentioned machining head mechanism and machining center are provided with a ram 100 and a swing head assembly 200 rotatably arranged at the lower end of the ram 100. The ram 100 has an inner cavity 101 extending in height, and an opening is arranged on the top side of the inner cavity 101; a connecting pipeline 300 connected to the swing head assembly 200 is arranged in the inner cavity 101, and a pipeline connection plate 400 and a fixed connection piece 500 are arranged at the upper end of the ram 100. The pipeline connection plate 400 is rotatably arranged at the upper end and is located at the At the opening position, the pipeline connection plate 400 is provided with a fixing portion 410 corresponding to each of the connecting pipelines 300, and the fixing portion 410 has a through hole 411 matching the cross section of the corresponding connecting pipeline 300, and each of the connecting pipelines 300 is fixed in the corresponding through hole 411; in this way, when the main shaft in the swing head assembly 200 swings, compared with the original structure in which the connecting pipeline 300 and the ram are fixed, the rotatable pipeline connection plate 400 can provide a length margin of the connecting pipeline 300 for the swing head assembly 200 to pull. It can be understood that the present application cleverly utilizes the rotation of the pipeline connection plate 400 to provide some margin of the connecting pipeline 300 to adapt to the length requirement of the connecting pipeline 300 caused by the swing of the swing head assembly 200 during the swing process, and the connecting pipeline 300 can be set shorter, thereby avoiding problems such as scratches on the upper cavity wall of the ram 100 and damage to the connecting pipeline 300.

[0057] The fixed connecting member 500 includes a connecting end 501 connected to the corresponding connecting pipeline 300. The connecting pipeline 300 is rotatably connected to the connecting end 501 so that the connecting pipeline 300 can rotate relative to the slide 100 together with the pipeline connecting plate 400. By setting the connecting end 501, each connecting pipeline 300 can rotate at a certain angle along with the swing of the swing head assembly 200, which will not cause the single connecting pipeline 300 itself to twist, and the risk of breaking the connecting pipeline 300 can be avoided.

[0058] The utility model also provides a machining center, including the above-mentioned machining head mechanism. In some feasible embodiments, the machining center further includes a slide saddle 1200, a slide groove is vertically arranged inside the slide saddle 1200, and at least three surfaces of the slide ram 100 are slidably connected to the groove surface of the slide groove.
