[0030] In combination Figure 1 , Figure 2As shown, the embodiment provides a multi-jaw machining mechanism, which comprises a rack 1, a rotating platform 2 and a plurality of clamping driving assemblies 3. The rotating platform 2 is rotatably installed on the rack 1, and the plurality of clamping driving assemblies 3 are arranged around the rotating platform 2, so that the plurality of clamping driving assemblies 3 can simultaneously correspond to a plurality of machining devices. The clamping driving assembly 3 comprises a control unit 31 and a mechanical jaw 32. The control unit 31 can control the mechanical jaw 32 to execute one of a rotating instruction and an opening and closing instruction according to the machining device corresponding to the mechanical jaw 32.

[0031] Exemplarily, in the embodiment, the multi-jaw machining mechanism is used to simultaneously control a plurality of cylindrical battery steel shells to sequentially complete the machining processes of feeding clamping, cutting, deburring and polishing and discharging.

[0032] In specific use, one implementation is that the rotating platform 2 is provided with four clamping driving assemblies 3 around the periphery, and four machining devices are correspondingly provided on the outer periphery of the rotating platform 2, which are respectively a feeding mechanism 100, a cutting mechanism 200, a deburring and polishing mechanism 300 and a discharging mechanism 400. When the first mechanical jaw 32 corresponds to the feeding mechanism 100, the control unit 31 can control the first mechanical jaw 32 to open and close, so that the first mechanical jaw 32 can clamp the first cylindrical battery steel shell on the feeding mechanism 100.

[0033] Subsequently, the rotating platform 2 rotates in a specified direction, so that the first mechanical jaw 32 rotates to a position corresponding to the cutting mechanism 200. The control unit 31 controls the mechanical jaw 32 to rotate, so that the cutting mechanism 200 can perform cutting machining on the mouth of the first cylindrical battery steel shell. At the same time, the second mechanical jaw 32 corresponds to the feeding mechanism 100, so that the control unit 31 corresponding to the second mechanical jaw 32 can control the second mechanical jaw 32 to open and close, so that the second mechanical jaw 32 can clamp the second cylindrical battery steel shell on the feeding mechanism 100.

[0034] Subsequently, the rotating platform 2 continues to rotate, so that the first mechanical jaw 32 rotates to correspond to the deburring and polishing mechanism 300 for polishing processing, the second mechanical jaw 32 rotates to correspond to the cutting mechanism 200 for cutting processing, and the third mechanical jaw 32 rotates to correspond to the feeding mechanism 100 for feeding the third cylindrical battery steel shell.

[0035] Subsequently, the rotating platform 2 continues to rotate, so that the first cylindrical battery steel shell can be discharged through the discharging mechanism 400, the second cylindrical battery steel shell is polished through the deburring polishing mechanism 300, the third cylindrical battery steel shell is cut through the cutting mechanism 200, and the fourth cylindrical battery steel shell is installed on the fourth mechanical clamp jaw 32 through the feeding mechanism 100. In this way, by arranging a plurality of clamping driving assemblies 3 on the rotating platform 2, and each mechanical clamp jaw 32 can be opened and closed and rotated individually, so that the feeding, cutting, deburring polishing and discharging processes can be carried out simultaneously, thereby improving the process efficiency, shortening the overall processing cycle, and realizing an efficient and automated production process.

[0036] It can be understood that in other alternative embodiments, other types of workpieces to be processed can also be selected for use, and the cross-sectional shape of the workpiece to be processed is not limited, for example, the cross-sectional shape of the workpiece to be processed can also be square, oval, etc.

[0037] Preferably, in the present embodiment, a plurality of processing devices are integrated and installed on the rack 1, thereby facilitating overall movement and adjustment, and the rack 1 is provided with adjustable height supporting feet, which ensures that each processing device remains horizontally stable during operation, further improving the processing accuracy and the reliability of the device operation.

[0038] Specifically, in the present embodiment, as shown in Figure 2 The rotating platform 2 includes a second rotating motor 21 and a turntable 22, wherein the fixed end of the second rotating motor 21 is fixedly arranged on the rack 1, the output end of the second rotating motor 21 is drivingly connected to the center shaft of the turntable 22, and the turntable 22 is uniformly provided with the above-mentioned four clamping driving assemblies 3. The second rotating motor 21 controls the rotation speed and angle of the turntable 22 accurately, ensures that each clamping driving assembly 3 accurately docks with the corresponding processing device at the predetermined position, and realizes seamless connection of each process.

[0039] Specifically, in the present embodiment, continuing to refer to Figure 2As shown, the control unit 31 comprises a first rotary motor 311 and a clamping cylinder 312, the fixed end of the first rotary motor 311 is fixedly arranged on the rotating disc 22, the output end of the first rotary motor 311 is drivingly connected to the fixed end of the clamping cylinder 312 through a connecting plate, and the output end of the clamping cylinder 312 is drivingly connected to the mechanical clamping jaw 32. Through the above arrangement, when the mechanical clamping jaw 32 corresponds to the feeding mechanism 100 or the discharging mechanism 400, the clamping cylinder 312 can timely control the mechanical clamping jaw 32 to execute the opening and closing instruction, so that the cylindrical battery shell can be automatically fed or discharged, or when the mechanical clamping jaw 32 corresponds to the cutting mechanism 200 or the deburring and polishing mechanism 300, the rotating disc 22, the clamping cylinder 312 and the mechanical clamping jaw 32 can be timely rotated by switching to the first rotary motor 311 to control the rotating disc 22, so as to realize the cutting and deburring and polishing treatment of the mouth of the cylindrical battery shell, so that each cylindrical battery shell can be independently processed at different processing equipment positions, thereby realizing the beneficial effects of strong independence and high production efficiency.

[0040] Further, the mechanical clamping jaw 32 comprises four clamping fingers to improve the clamping stability of the cylindrical battery shell and ensure the accurate positioning of the cylindrical battery shell during processing, thereby improving the quality of finished products.

That is to say, when two clamping and driving assemblies 3 correspond to the feeding mechanism 100 and the discharging mechanism 400 respectively, and the remaining two clamping and driving assemblies 3 correspond to the cutting mechanism 200 and the deburring and polishing mechanism 300 respectively, the control element can send on-off instructions to the on-off valves 314 corresponding to the four clamping and driving assemblies 3 at the same time, so that the rotary driving instructions generated by the control element can be sent to the corresponding two drivers 313 to control the corresponding two first rotary motors 311 to be turned on, so that the mechanical clamping jaws 32 in the clamping and driving assemblies 3 corresponding to the cutting mechanism 200 and the deburring and polishing mechanism 300 start to rotate; at the same time, the opening and closing driving instructions generated by the control element can be sent to the remaining two drivers 313, so as to control the corresponding two clamping cylinders 312 to be turned on, so that the mechanical clamping jaws 32 in the clamping and driving assemblies 3 corresponding to the feeding mechanism 100 and the discharging mechanism 400 perform opening and closing actions, thereby ensuring that each processing equipment can work synchronously and coordinately.

[0042] In addition, when only a part of the mechanical clamping jaw 32 has the cylindrical battery shell, the control element sends a turn-on instruction to the opening and closing valve 314 corresponding to the clamping driving assembly 3 with the cylindrical battery shell, so that the control instruction of the control element can be transmitted to the corresponding clamping driving assembly 3 to realize normal operation processing, and at the same time, the control element sends a turn-off instruction to the opening and closing valve 314 corresponding to the clamping driving assembly 3 without the cylindrical battery shell, so that the control element cannot send a control instruction to the clamping driving assembly 3, and the idle rotation of part of the first rotating motor 311 and part of the clamping jaw cylinder 312 is avoided, thereby reducing the waste of energy and further improving the operation efficiency and automatic control ability of the multi-jaw processing mechanism.

[0043] Further, the opening and closing valve 314 is an electromagnetic valve, which has the characteristics of fast response speed and accurate control. After receiving the turn-on or turn-off instruction of the control element, the electromagnetic valve can quickly adjust the gas path state to ensure fast response and accurate action.

[0045] Optionally, the multi-jaw processing mechanism provided in the embodiment further comprises a second sensor in signal connection with the control element, the second sensor being used for detecting whether the mechanical clamping jaw 32 and the cylindrical battery shell are in the same concentricity. If the concentricity detection result shows that the mechanical clamping jaw 32 and the cylindrical battery shell are not aligned, the second sensor sends a signal, and the control element displays the signal on the control terminal to send an alarm information to the staff, reminding the staff to handle in time, so as to ensure the processing precision and product quality, and prevent material waste caused by improper operation.

In addition, a plurality of clamping driving assemblies 3 are installed on the rotating disc 22, and a plurality of drivers 313 and a plurality of opening and closing valves 314 are installed on the electric control mounting plate 23, so that the driver 313 and the opening and closing valve 314 can be connected with the corresponding first rotating motor 311 and clamping jaw cylinder 312 respectively, thereby ensuring that when the rotating disc 22 rotates, the driver 313 can accurately transmit the control signal of the control element to the first rotating motor 311 and the clamping jaw cylinder 312, so as to ensure the instant execution of the action.

[0047] More specifically, the rotating platform 2 further comprises a plurality of support stands 24 fixedly arranged on the rotating disc 22, the support stands 24 are provided with four, and each is connected to the first rotating motor 311, and the first rotating motor 311 is horizontally installed on a vertical installation surface of the support stand 24, so that the first rotating motor 311, the jaw cylinder 312 and the mechanical jaw 32 can be sequentially connected in the horizontal direction, thereby facilitating the docking and processing of the cylindrical battery shell by each processing equipment, and facilitating the observation and detection of the processing condition by the staff.
