It should be noted that the embodiments and features of the embodiments of the present invention may be combined with one another unless there is a conflict.

[0038] Embodiment 1 of a multi-station tool provided by the present invention:

[0039] like Figure 1 As shown, a multi-station tooling includes a base 1 fixed on a drilling platform and two positioning units installed on the base 1. The two positioning units have the same structure. In this embodiment, one of the positioning units will be described in detail below as an example.

[0040] like Figure 1 、 Figure 2 and Figure 3 As shown, the positioning unit includes a mounting base 2, a tank cover clamping member 3, a tank cover positioning member 8, a driving member, an anti-loosening plate 15, an anti-pinch plate 14, an air source processor 12, and a pneumatic valve 10. In this embodiment, for ease of description, the length direction of the base 1 is defined as the front-to-back direction, the width direction of the base 1 is defined as the left-to-right direction, and the height direction of the base 1 is defined as the up-down direction.

[0041] like Figure 1 、 Figure 4 、 Figure 6 and Figure 7As shown, the mounting base 2 is fixed to the base 1 by fastening bolts. The mounting base 2 is provided with five can lid placement stations 20 arranged side by side and evenly spaced in the front-to-back direction, and a receiving groove with the notch facing downward. The receiving groove is provided with a U-shaped top plate 22 to support the mounting base 2 and prevent it from collapsing during processing.

[0042] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, the driving member is a double-rod cylinder 7. Five double-rod cylinders 7 are connected to the outside of each tank cover clamping member 3 via fastening bolts. The five double-rod cylinders 7 are fixed to the mounting base 2 via fastening bolts. The output ends of the five double-rod cylinders 7 are connected to the corresponding tank cover clamping members 3 via fastening bolts. The five double-rod cylinders 7 correspond one-to-one with the five tank cover positioning members 8 mentioned above, and the five double-rod cylinders 7 are arranged side by side in the front-to-back direction. The air intake ports of the ten double-rod cylinders 7 are connected to the same air pipe 17, and the exhaust ports of the ten double-rod cylinders 7 are connected to the same air pipe 17, which ensures the synchronization of the movement of the double-rod cylinders 7. If one of the double-rod cylinders 7 fails, the other double-rod cylinders 7 can still work, thereby improving the reliability of the system. A pipe cavity 23 is formed between the mounting seat 2 and the base 1 for the air pipe 17 to pass through. The air pipe 17 passes through the pipe cavity 23 so that it is not exposed outside the mounting seat 2, which is aesthetically pleasing and prevents the air pipe 17 from being scratched during tool processing. A plurality of through holes 21 are provided on the side wall of the accommodating groove for the air pipe 17 to pass through.

[0043] like Figure 1 and Figure 2 As shown, the tank cover positioning member 8 is a sleeve, and a sleeve is welded on each tank cover placement station 20. A baffle 11 is provided between two adjacent sleeves to prevent the tank cover 4 to be processed from being excessively deflected when personnel place the tank cover 4 to be processed.

[0044] like Figure 1 、 Figure 2 and Figure 5 As shown, the tank cover clamp 3 is a split structure, comprising a clamping portion and a pressing portion. The clamping portion is a clamping block 18, and the pressing portion is a pressing plate 19. The clamping block 18 is provided with an arc-shaped clamping groove 16 corresponding one-to-one to the tank cover placement station 20, and the arc-shaped clamping groove 16 is adapted to the outer periphery of the tank cover 4 to be processed. The pressing plate 19 is provided with an arc-shaped avoidance groove corresponding one-to-one to the tank cover placement station 20 to prevent the tool from hitting the pressing plate 19 during processing. The pressing plate 19 is fixedly connected to the top of the clamping block 18 by fastening bolts and extends outward from the clamping block 18 in the left-right direction. The clamping block 18 clamps the tank cover 4 to be processed in the left-right direction, and the pressing portion presses the tank cover 4 to be processed in the up-down direction. The combination of the two clamps the tank cover 4 to be processed, providing more accurate positioning and greater stability. The output end of the above-mentioned double-rod cylinder 7 is connected to the clamping block 18.

[0045] like Figure 1 、 Figure 2 and Figure 3 As shown, each clamping block 18 and pressing plate 19 is provided with two slots 13 at the front and rear ends, respectively. Two anti-loosening plates 15 are provided. The two anti-loosening plates 15 are respectively inserted into the two slots 13 located on the same side from top to bottom. When the tank cover clamp 3 is in the clamped state, the anti-loosening plates 15 are inserted into the corresponding slots 13, clamping the two tank cover clamps 3 to prevent the tank cover 4 to be processed from being thrown out due to excessive force during processing. Anti-pinch seats 9 are provided on the front and rear sides of the tank cover clamp 3, respectively. Slides are provided within the anti-pinch seats 9. Two anti-pinch plates 14 are provided. The two anti-pinch plates 14 slide within the corresponding slides to extend between the two tank cover clamps 3 at the front and rear ends of the tank cover clamp 3. When the tank cover clamp 3 is in the loose state, the anti-pinch plates 14 extend between the two tank cover clamps 3 to prevent accidental operation when replacing the tank cover 4 to cause the tank cover clamp 3 to clamp and injure personnel.

[0046] like Figure 1 As shown, a mounting plate is provided on the rear side of the mounting seat 2, and the above-mentioned pneumatic valve 10 and the air source processor 12 are located on the mounting plate. The pneumatic valve 10 and the air source processor 12 are connected through the air pipe 17, and the pneumatic valve 10 is connected to the double-rod cylinder 7 through the air pipe 17. The extension and retraction of the piston rod of the double-rod cylinder 7 are controlled by the pneumatic valve 10. The air source processor 12 is a pneumatic component device for processing compressed air. The air source processor 12 is an existing technology, and its function is to provide clean, stable pressure and lubricated compressed air for the pneumatic system to ensure the normal operation of the pneumatic system.

[0047] like Figure 1 As shown, a mounting groove is provided on the base 1, and two positioning units are fixed in the mounting groove at intervals in the left and right directions. A sewage pipe 5 is provided on the base 1 and connected to the mounting groove. A filter screen 6 is installed at the sewage pipe 5 within the mounting groove. Wastewater generated during processing flows into the mounting groove and then flows out through the sewage pipe 5. Copper chips generated during processing are present in the sewage. The filter screen 6 can filter out these copper chips for recycling and resource conservation.

[0048] The working process of this utility model is as follows:

[0049] When the tank cover clamping parts 3 are in the loose state, the anti-pinch plate 14 is extended between the two tank cover clamping parts 3, and multiple tank covers 4 to be processed are manually put on the corresponding sleeves, the anti-pinch plate 14 is taken out, and the pneumatic valve 10 is opened. The piston rod of the double-rod cylinder 7 pushes the tank cover clamping parts 3 to clamp the tank cover 4 to be processed to fix its position, and then the anti-loosening plate 15 is clamped in the corresponding slot 13, and then it can be automatically processed according to the CNC program.

[0050] The utility model is provided with a plurality of can lid placing stations 20 so that a plurality of can lids 4 to be processed can be processed at one time, thereby greatly improving the operation efficiency.

[0051] Embodiment 2 of a multi-station tool provided by the present invention:

[0052] The main difference between this embodiment and Example 1 is that: in Example 1, the multi-station tooling is provided with two left and right positioning units. In this embodiment, the multi-station tooling can be provided with three positioning units arranged at intervals on the left and right, and the number of positioning units can also be set according to the actual production and processing requirements.

[0053] Embodiment 3 of a multi-station tool provided by the present invention:

[0054] The main difference between this embodiment and the first embodiment is that in the first embodiment, the driving member is a double-rod cylinder. In this embodiment, an electric push rod can be used.

[0055] Embodiment 4 of a multi-station tool provided by the present invention:

[0056] The main difference between this embodiment and Example 1 is that, in Example 1, a can lid clamping member is driven by a number of driving members equal to the number of workstations. In this embodiment, a can lid clamping member can also be driven by a number of driving members less than the number of workstations. The number of driving members used can be selected according to actual needs, as long as it can ensure that the can lid to be processed can be clamped.

[0057] Embodiment 5 of a multi-station tool provided by the present invention:

[0058] The main difference between this embodiment and Example 1 is that, whereas the tank cover clamp in Example 1 employed a split structure, comprising a detachably connected clamping block and a pressure plate, this embodiment can employ a one-piece structure, with a clamping portion and a pressure portion adapted to the tank cover.

[0059] Example 6 of a multi-station tool provided by the present invention:

[0060] The main difference between this embodiment and Example 1 is that, whereas in Example 1, the left and right sides of each can lid placement station share a common can lid clamping member, this embodiment provides a separate can lid clamping member on each side of each can lid placement station. The can lid clamping members at different can lid placement stations are independent of each other and do not affect each other. In this embodiment, each can lid clamping member is connected to a driving member.
