[0031] Referring to the attached Figures 1-4 , a frog clamping workbench includes a processing table 1, on the top surface of the processing table 1, a frog body 2 to be processed is placed. On both sides of the processing table 1 and located on both sides of the frog body 2, a plurality of clamping mechanisms are provided. The clamping mechanism includes a plurality of independently movable side pressing blocks 3, and the side pressing blocks 3 abut against both side walls of the frog body 2; a support base 4 is fixedly connected to the bottom wall of the processing table 1, a fixed frame 5 is fixedly provided inside the support base 4, a dust suction mechanism is provided inside the fixed frame 5, a through groove is opened in the middle of the inner side of the processing table 1, a chip collecting plate 6 is installed in the through groove, a plurality of dropping ports 601 are evenly opened on the chip collecting plate 6, and the dust suction mechanism is located below the chip collecting plate 6; a cleaning assembly is provided above the processing table 1.

[0032] In this embodiment, the clamping mechanism further includes extension plates 7. A plurality of extension plates 7 are evenly distributed on both sides of the processing table 1. Hydraulic cylinders 8 are fixedly provided on a plurality of extension plates 7. The end of the actuating rod of the hydraulic cylinder 8 is connected to one side wall of the side pressing block 3. A plurality of sliding grooves 9 are opened on the top of the processing table 1, and one end of the sliding groove 9 extends to the top of the extension plate 7. The bottom end of the side pressing block 3 is slidably connected to the inside of the sliding groove 9.

[0033] It should be noted that the actuating rod of the hydraulic cylinder 8 of the clamping mechanism extends outwards to push the side pressing block 3 to slide inside the sliding groove 9, so that the side pressing block 3 moves towards the frog body 2 until the side pressing block 3 abuts against the side wall of the frog body 2. The independent operation of a plurality of side pressing blocks 3 can realize the clamping of the frog body 2. After the frog body 2 is clamped, some processing operations can be carried out on the upper surface of the frog body 2.

[0034] In this embodiment, the clamping mechanism further includes a steering groove 22. The steering groove 22 is independently opened on the top of the side pressing block 3. A connecting block 24 is connected to the top of the side pressing block 3 through a spring 23. The top end of the connecting block 24 is rotatably connected to an upper pressing block 25 through a bearing, and the upper pressing block 25 can also press on the upper surface of the frog body 2.

[0035] It should be noted that when it is necessary to change to side processing, the actuating rod of the hydraulic cylinder 8 can be retracted to bring the side pressing block 3 away from the frog body 2. After leaving a certain distance, by rotating the upper pressing block 25 to make it turn to one side of the frog body 2, and under the elastic action of the spring 23, the upper pressing block 25 is pressed on the upper surface of the frog body 2, and then the side of the frog body 2 can be processed.

[0036] In this embodiment, the dust suction mechanism includes two movable boxes 10 that can be pulled out. The two movable boxes 10 are respectively arranged on the left and right sides inside the fixed frame 5. In the middle of the inner side of the fixed frame 5, there are two partitions 11 connected. Inside the partitions 11, there are two dust extractors 12. The output ends of the two dust extractors 12 are both connected with dust suction pipes 13. The dust suction pipes 13 pass through the inner side of the partitions 11, and the suction ports of the dust suction pipes 13 are located inside the movable boxes 10.

[0037] It should be noted that when the two dust extractors 12 are started, by the suction force of the dust extractors 12, the iron filings are sucked downward through the dust suction pipes 13, so that the iron filings enter the inside of the movable boxes 10 through a number of dropping ports 601, realizing the cleaning and collection of the iron filings.

[0038] In this embodiment, the cleaning component includes a water tank 14. The water tank 14 is connected to the right side wall of the support base 4. Water pumps 15 are installed on both sides of the water tank 14. The input ends of the water pumps 15 are communicated with the inside of the water tank 14. The output ends of the water pumps 15 are connected with spray pipes 16. The two spray pipes 16 are located on the front and rear sides above the processing table 1. A number of spray holes 1601 are opened on the side walls of the spray pipes 16 facing the processing table 1.

[0039] It should be noted that by starting the water pumps 15, the water inside the water tank 14 can be pumped into the inside of the spray pipes 16, and finally sprayed onto the processing table 1 and the frog body 2 through a number of spray holes 1601, realizing the cleaning of the processing table 1 and the frog body 2.

[0040] In this embodiment, a weight sensor is arranged at the inner bottom of the movable box 10. A side seat 17 is fixedly connected to the lower part of the front side wall of the support base 4. A motor 18 is installed at one end of the side seat 17. The weight sensor is electrically connected to the motor 18. The output end of the motor 18 is connected with a bidirectional screw rod 19. The other end of the bidirectional screw rod 19 is rotatably connected to the other end of the side seat 17. Movable blocks 20 are symmetrically and threadedly sleeved on the outside of the bidirectional screw rod 19. A horizontal groove 1701 is opened on the top surface of the side seat 17. The bottom ends of the movable blocks 20 are slidably connected to the inside of the horizontal groove 1701. The top ends of the movable blocks 20 are fixedly connected with moving doors 21. The two moving doors 21 are slidably attached to the front side wall of the support base 4.

[0041] It should be noted that when the iron filings, impurities, etc. collected inside the movable box 10 reach a certain weight, the weight sensor at the bottom receives the signal and controls the motor 18 to start, thereby driving the bidirectional screw rod 19 to rotate. The bidirectional screw rod 19 drives the two movable blocks 20 to slide in the horizontal groove 1701 in the opposite direction, so that the two moving doors 21 move in the opposite direction, opening the front side of the support base 4. Then the staff can take out the movable box 10 from it, making the cleaning operation of the processing table 1 more convenient.

[0042] Working principle of the utility model: After the frog body 2 is hoisted onto the processing table 1 in place by a hoisting machine, the control system is manually operated to select the operation according to the specification model of the frog body 2. After the program runs, the actuator rod of the hydraulic cylinder 8 of the clamping mechanism extends outwards to push the side pressing block 3 to slide inside the sliding groove 9, so that the side pressing block 3 moves towards the frog body 2 until the side pressing block 3 abuts against the side wall of the frog body 2. The independent operation of multiple side pressing blocks 3 can realize the clamping of the frog body 2. After the frog body 2 is clamped, some processing operations can be carried out on the upper surface of the frog body 2; when it is necessary to change to side processing, the actuator rod of the hydraulic cylinder 8 can be retracted to bring the side pressing block 3 away from the frog body 2. After leaving a certain distance, by rotating the upper pressing block 25, it is turned to one side of the frog body 2, and under the elastic action of the spring 23, the upper pressing block 25 is pressed against the upper surface of the frog body 2, and then the side of the frog body 2 can be processed. A large amount of iron filings will be generated during the operation process, and the iron filings will fly everywhere due to mechanical force, so that the processing table 1 and the frog body 2 are stained with iron filings. Therefore, by starting the water pump 15, the water inside the water tank 14 can be pumped into the inside of the spray pipe 16, and finally sprayed onto the processing table 1 and the frog body 2 through a number of spray holes 1601, which can realize the cleaning of the processing table 1 and the frog body 2. At the same time, two dust collectors 12 are started, and by using the suction force of the dust collectors 12, the iron filings are sucked down through the dust suction pipe 13, so that the iron filings enter the inside of the movable box 10 through a number of dropping ports 601, realizing the cleaning and collection of the iron filings. When the iron filings, impurities, etc. collected inside the movable box 10 reach a certain weight, the weight sensor at the bottom receives the signal and controls the motor 18 to start, thereby driving the bidirectional screw 19 to rotate. The bidirectional screw 19 drives two movable blocks 20 to slide in the horizontal groove 1701 in the reverse direction, so that the two movable doors 21 move in the reverse direction, and the front side of the support seat 4 can be opened, and then the staff can take out the movable box 10 from it, making the cleaning operation of the processing table 1 more convenient. After the upper surface processing is completed, the frog body 2 can be flipped by hoisting so that its lower surface faces upwards, and then the above operations can be continued to complete the processing of the frog body 2.

[0043] The above embodiments only express a certain implementation mode of the utility model, and its description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent; it should be pointed out that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model; therefore, the protection scope of the utility model patent should be subject to the appended claims.
