Description

Technical Field

[0001] The utility model relates to the technical field of industrial processing equipment, in particular to a modular reconfigurable flexible machining center. Background Technique

[0002] In the traditional industrial manufacturing field, each workbench in the factory building is divided into multiple different production lines to manufacture different products. The advantage of this fixed production line mode is that it is suitable for mass production and processing of products, and the production speed is fast. However, for some small enterprises with small production batches or production and processing of multiple different products, the flexibility of this production mode is low, and personalized customization cannot be realized, which is prone to the defect of low equipment utilization rate. Therefore, modular processing equipment needs to be used for operation, which can greatly reduce the occupied area of production machinery. When producing different materials, it can be flexibly scheduled in a timely manner to improve the operation flexibility of the production line.

[0003] However, in the actual use process of the above equipment, since the processing equipment for workpieces has a certain size, usually multiple processing equipment are arranged on a convertible adjustment disk. When corresponding production processes are required, the corresponding equipment can be adjusted to move to the working area to realize the conversion of the production line process. However, when these equipment are integrally arranged on an adjustment disk, during both the adjustment process and the operation process, the adjustment disk itself is prone to external mechanical vibration, resulting in the risk of equipment deviation, and further leading to the reduction of the overall processing quality of the device. In view of this, we propose a modular reconfigurable flexible machining center. Content of the Utility Model

[0004] The purpose of the utility model is to provide a modular reconfigurable flexible machining center to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A modular reconfigurable flexible machining center, including a base, a vertical plate is fixedly installed on the upper surface of the base, a threaded drive plate is slidably installed on the inner wall of the vertical plate, a rotating shaft is penetrated and rotatably installed on the inner wall of the threaded drive plate, an adjustment disk is fixedly installed on the outer wall of one end of the rotating shaft, a processing module is fixedly installed on the outer wall of the adjustment disk away from the vertical plate, and an adjustment component is arranged inside the vertical plate. The adjustment component includes:

[0006] Adjusting motor, an adjusting motor is fixedly installed on the upper surface of the vertical plate. The output end of the adjusting motor is fixedly installed with an adjusting lead screw, and the adjusting lead screw is threadedly connected to the threaded transmission plate. On the outer wall of the threaded transmission plate away from the adjusting disc, a U-shaped frame is fixedly installed. On the outer wall of the U-shaped frame, a servo motor is fixedly installed. One end of a rotating rod is fixedly connected to the output end of the servo motor, and a sector block is fixedly installed on the arc-shaped outer wall at the other end of the rotating rod.

[0007] Active gear ring, an active gear ring is rotatably installed on the outer wall of the vertical plate close to the adjusting disc. On the arc-shaped inner surface of the active gear ring, a sector-shaped clamping block is fixedly installed. A driven gear ring is sleeved on the outer wall of the rotating shaft. The rotating rod passes through and is fixedly installed with a flywheel. A transmission wheel is movably installed on the arc-shaped outer wall of the rotating shaft. On the outer wall of the transmission wheel close to the vertical plate, a limiting block is fixedly installed. An elastic member is fixedly installed on the side wall of the transmission wheel. An inclined surface is arranged on the outer wall of the transmission wheel close to the vertical plate, and a limiting groove is opened on the inner wall of the vertical plate close to the transmission wheel.

[0008] Preferably, the number of the processing modules is set to be multiple groups, and the multiple groups of processing modules are evenly distributed in a circumferential array on the side wall of the adjusting disc, so that multiple sets of equipment for processing can be erected on the adjusting disc at the same time.

[0009] Preferably, the sector block is arranged inside the active gear ring, and the size of the sector block is one-fourth of the inner circle size of the active gear ring, and the size of the sector-shaped clamping block is the same as that of the sector block.

[0010] Preferably, the flywheel includes a disc and sector plates arranged on the arc-shaped outer wall of the disc. The number of the sector plates is set to be two groups, and the two groups of sector plates are mirror-symmetrically arranged on the left and right sides of the disc. The thickness of the flywheel is adapted to the width of the inclined surface opened on the side surface of the transmission wheel. Thus, when the rotating rod drives the flywheel to rotate, the transmission wheel will move horizontally away from the vertical plate along the outer wall of the rotating shaft.

[0011] Preferably, a square limiting strip adapted to the size of the square groove is arranged on the arc-shaped inner wall of the transmission wheel, and at the same time, the square limiting strip is arranged inside the square groove. Thus, the transmission wheel can only move horizontally on the arc-shaped outer wall of the rotating shaft and will not rotate relative to the rotating shaft. The elastic member is arranged inside the square groove.

[0012] Preferably, an auxiliary positioning mechanism is provided inside the limit block. The auxiliary positioning mechanism includes an elastic airbag. The inside of the limit block is hollow, and an elastic airbag is fixedly installed in the inner cavity of the limit block.

A top rod is fixedly installed on the inner wall of the end of the limit groove. Auxiliary grooves are formed on the outer walls of the upper and lower sides of the limit groove.

[0013] Preferably, the elastic airbag is filled with inert gas so that the volume of the elastic airbag will not change significantly due to the influence of external temperature. The gas filling amount inside the elastic airbag is in a semi-full state.

[0014] Compared with the prior art, the present utility model provides a modular reconfigurable flexible machining center, which has the following beneficial effects:

[0015] 1. In this modular reconfigurable flexible machining center, by providing an adjustment component and cooperating with the settings of the sector block and the sector block, the sector block will only come into contact with the sector block and drive the driving gear ring and the driven gear ring to rotate after the servo motor has been started for a certain period of time. During this period, in cooperation with the inclined surfaces of the flywheel and the transmission wheel, the limit on the rotating shaft and the transmission wheel by the limit block is released, so that the machining position of a machining module can be changed every time the adjustment disk rotates one cycle, ensuring the stability during the conversion of the machining module and also ensuring the stable machining effect when the machining module is performing machining operations.

[0016] 2. In this modular reconfigurable flexible machining center, by providing an auxiliary positioning mechanism, after the limit block completely enters the limit groove, the gas inside the elastic airbag is pressed and filled into the extension airbag, so that the extension airbag is completely filled. Finally, the extension airbag closely fits in the auxiliary groove, increasing the contact area during the positioning of the limit block and ensuring the stability when the limit block keeps the transmission wheel and the rotating shaft in a relatively fixed state, improving the stable effect during the machining operation of the device.

Specific implementation manner

[0024] As Figures 1-6 shown, the present utility model provides a technical solution: a modular reconfigurable flexible machining center, including a base 1, a vertical plate 2 is fixedly installed on the upper surface of the base 1, a threaded drive plate 3 is slidably installed on the inner wall of the vertical plate 2, a rotating shaft 4 is penetrated and rotatably installed on the inner wall of the threaded drive plate 3, an adjusting disc 5 is fixedly installed on the outer wall of one end of the rotating shaft 4, a processing module 6 is fixedly installed on the outer wall of the adjusting disc 5 away from the vertical plate 2, an adjusting assembly 7 is arranged inside the vertical plate 2, and the adjusting assembly 7 includes an adjusting motor 71, an adjusting lead screw 72, a U-shaped frame 73, a servo motor 74, a rotating rod 75, a sector block 76, an active tooth ring 77, a sector-shaped clamping block 78, a driven tooth ring 79, a flywheel 710, a transmission wheel 711, a limit block 712, an elastic member 713, an inclined surface 714 and a limit groove 715.

[0025] In an embodiment of the present utility model, an adjustment motor 71 is fixedly installed on the upper surface of the vertical plate 2. The output end of the adjustment motor 71 is fixedly installed with an adjustment lead screw 72. The adjustment lead screw 72 is threadedly connected to the threaded drive plate 3. On the outer wall of the threaded drive plate 3 away from the adjustment disc 5, a U-shaped frame 73 is fixedly installed. On the outer wall of the U-shaped frame 73, a servo motor 74 is fixedly installed. The output end of the servo motor 74 is fixedly connected to one end of a rotating rod 75. On the arc-shaped outer wall of the other end of the rotating rod 75, a sector block 76 is fixedly installed. On the outer wall of the vertical plate 2 close to the adjustment disc 5, a driving gear ring 77 is rotatably installed. On the arc-shaped inner surface of the driving gear ring 77, a sector-shaped clamping block 78 is fixedly installed. A driven gear ring 79 is sleeved on the outer wall of the rotating shaft 4. The rotating rod 75 passes through and is fixedly installed with a flywheel 710. On the arc-shaped outer wall of the rotating shaft 4, a transmission wheel 711 is movably installed. On the outer wall of the transmission wheel 711 close to the vertical plate 2, a limiting block 712 is fixedly installed. On the side wall of the transmission wheel 711, an elastic member 713 is fixedly installed. On the outer wall of the transmission wheel 711 close to the vertical plate 2, an inclined surface 714 is provided. On the inner wall of the vertical plate 2 close to the transmission wheel 711, a limiting groove 715 is opened.

[0026] Furthermore, a rectangular groove adapted to the threaded drive plate 3 is opened in the inner wall of the vertical plate 2. Thus, when the adjustment motor 71 is started, the threaded drive plate 3 can only move vertically along the inner wall of the vertical plate 2, so that the staff can change the height of the adjustment disc 5 according to actual needs to adapt to the processing requirements of different materials. At the same time, the number of processing modules 6 is set to be multiple groups, and the multiple groups of processing modules 6 are evenly distributed in a circumferential array on the side wall of the adjustment disc 5, so that multiple sets of processing equipment can be erected on the adjustment disc 5 at the same time to improve the processing adaptability of the device. In addition, the rotating rod 75 passes through the threaded drive plate 3, and the threaded drive plate 3 is rotatably connected to the rotating rod 75. And the output end of the servo motor 74 has a power-off self-locking function. After the servo motor 74 is turned off, the output end of the servo motor 74 will not rotate due to external force, thereby ensuring that the adjustment disc 5 will not easily shift after rotating to the target angle. At the same time, the sector block 76 is arranged inside the driving gear ring 77, and the size of the sector block 76 is one-fourth of the inner circle size of the driving gear ring 77, and the size of the sector-shaped clamping block 78 is the same as that of the sector block 76. Specifically, the driven gear ring 79 meshes with the driving gear ring 77 to achieve transmission. Thus, after the servo motor 74 is started, the rotating rod 75 rotates and drives the sector block 76 to rotate a certain angle, and then cooperates with the sector-shaped clamping block 78 to drive the driving gear ring 77 to rotate, thereby driving the driven gear ring 79 and the rotating shaft 4 to rotate, so as to adjust the positions of the adjustment disc 5 and the processing modules 6 installed on its side to adapt to the operation requirements of different specifications of equipment.

[0027] In addition, the flywheel 710 includes a disc and a sector plate provided on the arc-shaped outer wall of the disc. The number of sector plates is set to two groups, and the two groups of sector plates are mirror-symmetrically arranged on the left and right sides of the disc. At the same time, the thickness of the flywheel 710 is adapted to the width of the inclined surface 714 provided on the side surface of the transmission wheel 711. Thus, when the rotating rod 75 drives the flywheel 710 to rotate, due to the restriction of the sector plate of the flywheel 710 on the inclined surface 714, the transmission wheel 711 will move horizontally away from the side of the vertical plate 2 along the outer wall of the rotating shaft 4, so that the limit block 712 disengages from the limit groove 715. At the same time, a square groove is provided on the arc-shaped outer wall of the rotating shaft 4, and a square limit strip adapted to the size of the square groove is provided on the arc-shaped inner wall of the transmission wheel 711. The square limit strip is arranged inside the square groove, so that the transmission wheel 711 can only move horizontally on the arc-shaped outer wall of the rotating shaft 4 and will not rotate relative to the rotating shaft 4. Specifically, an elastic member 713 is arranged inside the square groove. The two ends of the elastic member 713 are respectively fixedly connected to the inner wall of the end of the square groove and the side wall of the transmission wheel 711. The elastic member 713 is composed of a telescopic rod and a spring. Thus, under the elastic force of the elastic member 713, the transmission wheel 711 always fits against the side wall of the threaded transmission plate 3 when not subjected to an external force. Further, the size of the limit block 712 is adapted to the limit groove 715, and the number of both the limit blocks 712 and the limit grooves 715 is set to five groups, and the five groups of limit blocks 712 and limit grooves 715 are evenly distributed in a circumferential array.

[0028] In an embodiment of the present invention, an auxiliary positioning mechanism 8 is provided inside the limit block 712. The auxiliary positioning mechanism 8 includes an elastic airbag 81. The inside of the limit block 712 is hollow, and the elastic airbag 81 is fixedly installed in the internal cavity of the limit block 712. Extension airbags 82 are fixedly installed on the upper and lower outer walls of the elastic airbag 81. A push plate 83 is slidably installed on the inner wall of the limit block 712. A top rod 84 is fixedly installed on the inner wall of the end of the limit groove 715. Auxiliary grooves 85 are provided on the upper and lower outer walls of the limit groove 715.

[0029] Specifically, the interior of the elastic airbag 81 is filled with inert gas so that the volume of the elastic airbag 81 will not change significantly due to the influence of the external air temperature. At the same time, the amount of gas filled inside the elastic airbag 81 is in a semi-full state, so that the extension airbag 82 will not be in a fully filled state when the elastic airbag 81 is not squeezed. Specifically, a round hole adapted to the size of the ejector rod 84 is provided on the inner wall of the end of the limit block 712. After the limit block 712 enters the limit groove 715 and moves a certain distance, the ejector rod 84 passes through the round hole and enters the internal cavity of the limit block 712. Then, as the limit block 712 continues to move, the ejector rod 84 pushes the push plate 83 to squeeze the elastic airbag 81. After the limit block 712 completely enters the limit groove 715, the gas inside the elastic airbag 81 is pressed and filled into the extension airbag 82, so that the extension airbag 82 is completely filled. Finally, the extension airbag 82 closely fits in the auxiliary groove 85, increasing the contact area when the limit block 712 is positioned, ensuring the stability when the limit block 712 keeps the relative fixed state between the transmission wheel 711 and the rotating shaft 4, and improving the stable effect during the processing operation of the device.

[0030] In the present utility model, during use, by starting the adjustment motor 71 and cooperating with the adjustment lead screw 72, the height of the threaded transmission plate 3 in the vertical plate 2 is adjusted. Then, the servo motor 74 is started to drive the rotating rod 75 to rotate. After the rotating rod 75 drives the sector block 76 to rotate by a certain ninety degrees, the sector block 76 fits with the sector latch 78 and drives the driving gear ring 77 to rotate as the rotating rod 75 rotates. During the process of the rotating rod 75 driving the sector block 76 to rotate to ninety degrees, the rotation of the flywheel 710 will drive the sector plate to squeeze the inclined surface 714, causing the transmission wheel 711 to move horizontally away from the vertical plate 2 along the outer wall of the rotating shaft 4, so that the limit block 712 disengages from the limit groove 715. After the limit block 712 disengages from the limit groove 715, at this time the sector block 76 just fits with the sector latch 78. Then, as the rotating rod 75 continues to rotate, the driving gear ring 77 drives the driven gear ring 79 to rotate, and then drives the rotating shaft 4 and the adjustment disk 5 to rotate. When the angle of one cycle (i.e., the distance between two limit blocks 712) is rotated, the limit block 712 re-enters the limit groove 715. At this time, the processing module 6 on the adjustment disk 5 completes the conversion of one working station, thus facilitating the processing production requirements of different modules in industrial production.

[0031] The above generally describes the present utility model in detail, but based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
