The aluminum piston is one of the pistons of the engine, and its function is to move up and down in the cylinder, seal the cylinder through piston rings, and transmit the pressure generated by combustion to the crankshaft, thereby driving the engine to work properly. During the processing of aluminum pistons, a milling machine is used for milling work, and a pneumatic clamping tooling is required to clamp and limit the workpiece. The multi-station milling pneumatic clamping tooling for aluminum pistons is usually a device used to fix and clamp aluminum pistons during the processing for milling. This kind of tooling usually adopts a pneumatic system to achieve rapid clamping and release, has multiple stations, and can continuously complete multiple processes;

[0003] However, the existing multi-station milling pneumatic clamping tooling for aluminum pistons has the following disadvantages. Since a lot of chips will be generated when the milling machine mills the aluminum piston workpiece, these chips will enter the inside of the pneumatic clamping tooling through the chute or through hole of the pneumatic clamping tooling, which is not convenient for the staff to clean and will affect the use of the pneumatic clamping tooling. Therefore, the existing multi-station milling pneumatic clamping tooling for aluminum pistons needs to be improved. Summary of the Invention

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 and Figure 7 , the present utility model provides a technical solution: a pneumatic clamping tooling for multi-station milling of aluminum pistons, including a base 1 and a clamping block 7. A chuck 2 is fixed above the base 1. A cylinder 3 is arranged in the built-in groove of the base 1. One end of the cylinder 3 close to the built-in groove of the chuck 2 is fixedly connected with a connecting plate 4. A support rod 11 is connected above the connecting plate 4 through a movable shaft. One end of the support rod 11 is connected with a slider 6 through a movable shaft. The clamping block 7 is arranged above the slider 6. A placement table 12 is fixed in the middle of the chuck 2. A chute 5 is opened above the chuck 2 close to the slider 6, and the chute 5 is slidably connected with the slider 6. The cross-sectional shape of the slider 6 is "I"-shaped.

[0025] According to Figures 1-3 and Figure 6As shown in the figure, mounting mechanisms 9 are connected to both sides of the chuck 2. Connecting bolts 14 are provided on both sides of the mounting mechanism 9. A first collection box 10 is installed in the built-in slot of the chuck 2 by bolts. Second collection boxes 15 are attached to both sides of the first collection box 10. The mounting mechanism 9 includes a docking groove 901, side plates 902, fixing blocks 903, and docking blocks 904. Side plates 902 are provided on both sides of the chuck 2. Docking blocks 904 are fixed at both ends of the side plates 902. Docking grooves 901 are formed on both sides of the chuck 2 close to the docking blocks 904. Fixing blocks 903 are fixed on both sides of the side plates 902 away from the docking blocks 904. The fixing blocks 903 are in threaded connection with the connecting bolts 14. The shapes of both the docking blocks 904 and the docking grooves 901 are "T" shaped. The connecting bolts 14 are in threaded connection with the chuck 2. The shape formed by the first collection box 10 and the second collection boxes 15 is circular.

[0026] During specific implementation, the debris generated by the milling of the aluminum piston by the milling machine enters the inside of the chuck 2 from the chute 5 or the gap. The first collection box 10 and the second collection boxes 15 are spliced into a circle inside the chuck 2 and can collect the debris. When it is necessary to clean the debris, by rotating the connecting bolt 14, the connecting bolt 14 is disengaged from the threaded hole of the chuck 2, and then the side plate 902 is pulled outwards, so that the side plate 902 drives the docking block 904 to slide outwards in the docking groove 901 and disengage from the docking groove 901, and the side plate 902 is detached from the chuck 2. Then the first collection box 10 is detached, and then the second collection boxes 15 are taken out, and the debris in the first collection box 10 and the second collection boxes 15 can be cleaned, preventing the debris from affecting the normal use of the pneumatic clamping tooling, and improving the practicability of the pneumatic clamping tooling for multi-station milling of aluminum pistons.

[0027] According to Figures 1-5 As shown in the figure, an installation groove 8 is formed inside the clamping block 7 close to the slider 6. A limiting mechanism 13 is provided on both sides of the clamping block 7 and the slider 6. The limiting mechanism 13 includes a limiting spring 131, a limiting block 132, a pressing rod 133, a reset spring 134, and a limiting groove 135. Pressing rods 133 penetrate through both sides of the clamping block 7. A reset spring 134 is sleeved on the outer side of the pressing rods 133. A limiting spring 131 is provided in the built-in slot of the slider 6. Limiting blocks 132 are provided at both ends of the limiting spring 131. The limiting blocks 132 are in sliding connection with the slider 6.

[0028] During specific implementation, the clamping block 7 on the pneumatic clamping tooling will experience wear after long-term use, resulting in unstable clamping. The clamping block 7 can be replaced. By pressing the pressure rod 133 simultaneously, the pressure rod 133 squeezes the return spring 134 and pushes the limit block 132. Then, the limit block 132 is separated from the limit groove 135 under the extrusion of the pressure rod 133, and the limit spring 131 is squeezed at the same time. Subsequently, the clamping block 7 can be pulled upward to separate the installation groove 8 from the slider 6, and the clamping block 7 can be quickly disassembled. Then, a new clamping block 7 is replaced, and the installation groove 8 is docked with the slider 6. Then, the rebound of the limit spring 131 drives the limit block 132 to engage with the limit groove 135, and the clamping block 7 is installed on the slider 6. The setting of the limit mechanism 13 can quickly replace the worn clamping block 7, extending the service life of the pneumatic clamping tooling for multi-station milling of aluminum pistons.

[0029] Working principle: When using this pneumatic clamping tooling for multi-station milling of aluminum pistons, first, the base 1 is installed on the milling machine through bolts. Subsequently, the aluminum piston workpiece is placed on the placement table 12, and the connecting plate 4 is pushed upward or pulled downward by the cylinder 3, so that the connecting plate 4 drives the support rod 11 to push or pull the slider 6 to slide in the chute 5. The width of the upper and lower parts of the slider 6 is greater than the width of the chute 5, so the slider 6 will not move up and down but only slide back and forth. Then, the slider 6 drives the clamping block 7 to clamp on the outside of the aluminum piston workpiece. During the milling process, some debris enters the inside of the chuck 2 from the chute 5 or the gap, and is collected by the first collection box 10 and the second collection box 15. Then, the first collection box 10 and the second collection box 15 are taken out for cleaning through the installation mechanism 9. When the clamping block 7 is worn and needs to be replaced, the clamping block 7 can be quickly disassembled through the limit mechanism 13, improving the practicability of the pneumatic clamping tooling for multi-station milling of aluminum pistons.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
