DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 6 As shown, a diesel engine flywheel processing device comprises a workbench 1, two movable racks 2 are movably arranged on the upper surface of the workbench 1, a rotating rod 3 is rotatably installed between the inner walls of the two movable racks 2, a plurality of arc-shaped clamping plates 4 are arranged on the rod bodies of the two rotating rods 3, a plurality of positioning tooth plates 5 are fixedly installed on one side of each arc-shaped clamping plate 4, and the sizes and spacings of the positioning tooth plates 5 arranged on one side of adjacent arc-shaped clamping plates 4 are different;

[0027] A support frame 6 is fixedly installed on both sides of the upper surface of the workbench 1. A mechanical arm 7 is installed on the top of the support frame 6. An electric drill bit 8 is arranged at one end of the mechanical arm 7.

[0028] A slide groove 9 is provided on the upper surface of the workbench 1, and two sliders 10 are slidably arranged in the slide groove 9, and the upper surfaces of the two sliders 10 are respectively fixedly connected to the corresponding moving frames 2;

[0029] A bidirectional screw rod 11 is rotatably mounted between the two sides of the inner wall of the slide groove 9, and two sliders 10 are respectively threadedly arranged on the two sides of the rod body of the bidirectional screw rod 11;

[0030] A first motor 12 is fixedly mounted on one side of the workbench 1 , and one end of the bidirectional screw rod 11 passes through the workbench 1 and is fixedly connected to the output shaft end of the first motor 12 .

[0031] One end of the two rotating rods 3 passes through the corresponding moving frame 2 and is sleeved with a first gear 13. The two moving frames 2 are fixedly installed with a second motor 14 on one side close to the first gear 13. The output shafts of the two second motors 14 are sleeved with a second gear 15, which is meshed with the first gear 13.

[0032] The staff places the flywheel on the boss on the surface of the workbench 1, and then starts the first motor 12, so that the output shaft end drives the bidirectional screw 11 to rotate, and the rotating bidirectional screw 11 drives the two sliders 10 and the movable frame 2 to move relative to each other by screwing in the thread, so that the two opposite arc-shaped clamping plates 4 are close to each other. With the cooperation of the arc-shaped clamping plates 4 and the positioning tooth plates 5, the flywheel is firmly clamped. Then the staff starts the mechanical arm 7 and the electric drill 8, so that the electric drill 8 moves to the flywheel to drill a hole in the flywheel. When clamping flywheels of different specifications, the staff starts the second motor 14 so that its output shaft end drives the second gear 15 to rotate. Under the meshing action of the second gear 15 and the first gear 13, the rotating rod 3 drives the corresponding arc-shaped clamping plate 4 to rotate. Since the spacing and size of the positioning tooth plates 5 arranged on one side of adjacent arc-shaped clamping plates 4 are different, it is convenient for the staff to move the arc-shaped clamping plate 4 that matches the positioning tooth plates 5 with the flywheel teeth to the clamping position, thereby clamping flywheels of different specifications, avoiding loosening of flywheels of different specifications during processing, and preventing the processing quality of the flywheel from being affected.

[0033] In another embodiment of the utility model, a plurality of mounting grooves 16 are provided on the surface of the shafts of the two rotating rods 3 , and a mounting plate 17 is inserted into each mounting groove 16 . One side of each mounting plate 17 is fixedly connected to the corresponding arc-shaped clamping plate 4 .

[0034] A connection block 18 is fixedly mounted on one side of each mounting plate 17, and a plug hole 19 is formed on the surface of each connection block 18 on the side away from the corresponding arc-shaped clamping plate 4;

[0035] A plurality of movable grooves 20 are provided on both sides of the rod body of each rotating rod 3, a movable block 21 is slidably arranged in each movable groove 20, an insert block 22 is fixedly installed on one side of each movable block 21, and an insert rod 23 is fixedly installed on one side of each insert block 22 close to the corresponding socket 19.

[0036] A slide bar 24 is fixedly installed between the two sides of the inner wall of each moving groove 20 , each moving block 21 is slidably arranged on one side of the corresponding slide bar 24 , and a spring 25 is sleeved on the other side of the slide bar 24 .

[0037] The staff moves the plug block 22 to drive the moving block 21 to move along the moving groove 20, and the spring 25 is compressed. Then the staff moves the mounting plate 17 out of the mounting groove 16, so as to facilitate the staff to disassemble the arc clamping plate 4. Then the staff will install the arc clamping plate 4 with different distances and sizes of positioning tooth plates 5, and insert the corresponding mounting plate 17 into the mounting groove 16. Then the plug block 22 is released, and the spring 25 is reset and drives the insertion rod 23 to be inserted into the socket 19, so that the staff can quickly replace the arc clamping plate 4 with different spacings and sizes of positioning tooth plates 5, so that the arc clamping plate 4 can clamp flywheels of more specifications, thereby increasing versatility.

[0038] The working principle of this diesel engine flywheel processing device:

[0039] When in use, the staff places the flywheel on the boss on the surface of the workbench 1, and then starts the first motor 12, so that the output shaft end drives the bidirectional screw 11 to rotate, and the rotating bidirectional screw 11 drives the two sliders 10 and the movable frame 2 to move relative to each other by screwing in the thread, so that the two opposite arc-shaped clamping plates 4 are close to each other. With the cooperation of the arc-shaped clamping plates 4 and the positioning tooth plates 5, the flywheel is firmly clamped, and then the staff starts the mechanical arm 7 and the electric drill 8, so that the electric drill 8 moves to the flywheel to drill a hole in the flywheel. When clamping flywheels of different specifications, the staff starts the second motor 14 so that its output shaft end drives the second gear 15 to rotate. Under the meshing action of the second gear 15 and the first gear 13, the rotating rod 3 drives the corresponding arc-shaped clamping plate 4 to rotate. Since the spacing and size of the positioning tooth plates 5 arranged on one side of adjacent arc-shaped clamping plates 4 are different, it is convenient for the staff to move the arc-shaped clamping plate 4 that matches the positioning tooth plates 5 with the flywheel teeth to the clamping position, thereby clamping flywheels of different specifications, avoiding loosening of flywheels of different specifications during processing, and preventing the processing quality of the flywheel from being affected.

It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
