DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.
[0023] Embodiment 1, refer to Figures 1 to 5A polishing device for the inner wall of an automotive engine intake manifold includes a worktable 1. Two sets of tanks 2 are connected to the worktable 1. The tanks 2 contain different abrasives for roughing and finishing the intake manifold. Each set of tanks 2 is equipped with a motor 3, the model of which can be selected according to actual needs. The output ends of both sets of motors 3 are connected to rocker arms 4. The motors 3 drive the rocker arms 4 to rotate. Both sets of rocker arms 4 are rotatably connected to a first connecting member 5. The rocker arms 4 drive the first connecting member 5 to rotate. Each of the connecting parts 5 is rotatably connected to a rod 6. The first connecting part 5 drives the rod 6 to reciprocate up and down. The two sets of rods 6 are respectively movably connected to the corresponding tanks 2. The tanks 2 guide the rods 6. One end of each set of rods 6 is connected to a piston 7. The piston 7 reciprocates up and down, squeezing the abrasive into the intake manifold. The abrasive flows in the intake manifold and polishes the intake manifold. The worktable 1 is provided with a first plate 8. The first threaded rod 9 is rotatably connected to the first plate 8. Rotating the first threaded rod 9 drives the first block 10 to move. The first threaded rod 9 is threadedly connected to the first block 10, which is slidably connected to the first plate 8. The first block 10 has a first groove 11, which drives the column 12 to slide in the second groove 13, thereby moving the intake manifold. The first groove 11 is slidably connected to the column 12. One end of the first plate 8 has a second groove 13, which is slidably connected to the column 12. One end of the column 12 is connected to a second plate 15, which is movably connected to the first block 10. The first block 10 limits the movement of the second plate 15. The second plate 15 has two sets of housings 16, which are rotatably connected to the second threaded rod 17. Rotating the second threaded rod 17 moves the second block 18, which in turn moves the housings 16 via the second connector 19, clamping the intake manifold. The second threaded rod 17... A second block 18 is connected to the first block 10. One end of the second block 18 is rotatably connected to a second connector 19. The two sets of second connectors 19 are rotatably connected to the corresponding housing 16. By rotating the first threaded rod 9, the first block 10 is moved, which in turn drives the column 12 to slide in the second groove 13 through the first groove 11, causing the intake manifold to move and fit against the canister 2. The motor 3 drives the rocker arm 4 to rotate, which in turn drives the piston 7 connected to one end of the rod 6 to reciprocate up and down through the first connector 5, squeezing the abrasive into the intake manifold to perform rough polishing on the inner wall of the intake manifold. The above process is repeated to move the intake manifold to fit against the next set of canisters 2 for fine machining of the intake manifold. To a certain extent, this eliminates the problem of frequently changing abrasives when roughing and finishing the intake manifold, thus improving efficiency.

The one end opening of the intake manifold is upward, which facilitates the entry of the abrasive into the interior of the intake manifold when the intake manifold is subsequently attached to the tank body 2. The other end opening of the intake manifold faces the direction opposite to the second groove body 13. After the protruding part of the intake manifold contacts part of the round rods 20, the round rods 20 will move towards the interior of the box body 16 and compress the spring 23. The remaining round rods 20 continue to move towards the direction of the intake manifold, and to a certain extent, the different shapes of the intake manifold are self-adapted clamped, and the applicability is relatively wide.

The first plate body 8 is moved by the electric push rod 14, the position of the first plate body 8 is adjusted, and then the position of the intake manifold is adjusted, so that the intake manifold of different sizes can be attached to the tank body 2 after moving. One end of the second threaded rod 17 and the first threaded rod 9 is connected with a hand wheel 22. The second threaded rod 17 and the first threaded rod 9 are more convenient to rotate through the hand wheel 22. The second plate body 15 is connected with a guide rod 21, the guide rod 21 is slidably connected with the second block 18, and the guide rod 21 guides the second block 18. One end of the plurality of groups of round rods 20 is connected with a rubber pad 25, which increases the friction force with the intake manifold and improves the clamping stability of the intake manifold to a certain extent. The second plate body 15 is provided with a third groove 24, the third groove 24 is slidably connected with the two groups of box bodies 16, and the third groove 24 guides the box body 16.
[0025] The working principle of the embodiment is as follows: when in use, the intake manifold is moved above the second plate body 15, and the opening at one end of the intake manifold is upward, so that the abrasive flows into the intake manifold when the intake manifold is later attached to the tank body 2, and the opening at the other end of the intake manifold faces the direction opposite to the second groove body 13, so that the abrasive flows out and is collected later, the second block body 18 is moved by rotating the second threaded rod 17, the second block body 18 is in contact with the protruding part of the intake manifold through the second connecting piece 19 and the partial circular rod 20 and compresses the spring 23, and the remaining part continues to move, so that the intake manifold can be self-adaptively clamped to a certain extent, the applicability is relatively wide, the height of the intake manifold is adjusted by moving the first plate body 8 driven by the electric push rod 14, so that intake manifolds of different sizes can be attached to one end of the tank body 2 after moving, the first block body 10 is moved by rotating the first threaded rod 9, the first groove body 11 drives the column body 12 to slide in the second groove body 13, and then drives the abrasive to move along the arc track of the second groove body 13, the intake manifold is attached to one end of the tank body 2 after moving a certain distance, the motor 3 is started to drive the rocker 4 to rotate, the rocker 4 drives the rod body 6 to reciprocally move through the first connecting piece 5, the abrasive previously stored in the tank body 2 is injected into the intake manifold, the abrasive flows in the intake manifold and rubs against the intake manifold, so that the intake manifold is rough machined, after machining, the intake manifold is moved to the next group of tank bodies 2 by rotating the first threaded rod 9, and the above process is repeatedly continued, so that the intake manifold is finish machined, the time for rough machining and finish machining of the intake manifold by frequently replacing abrasives is saved to a certain extent, and the polishing efficiency is improved to a certain extent.
