DETAILED DESCRIPTION

[0018] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0019] As Figures 1-4 shown, the present utility model provides a technical solution: a support structure for engine crankshaft machining, including a handle 1. One end of the handle 1 is installed with a sliding screw 3. A support plate 2 is installed outside the sliding screw 3. A slider 4 is provided on one side of the support plate 2. A bearing 12 is provided on the slider 4. A slide bar 13 is provided below the bearing 12. The number of slide bars 13 is two. The two ends of the slide bar 13 are installed in the operating table 14. Since there are two slide bars 13 in the operating table 14, the slider 4 can move on the slide bar 13, which plays a role in adjusting the machining position and improves the moving stability of the slider 4.

[0020] A rotating shaft 5 is installed on the slider 4. One end of the rotating shaft 5 is provided with a fixing plate 6. Two sliding plates 7 are installed on the fixing plate 6.

[0021] An upper clamping plate 11 and a lower clamping plate 23 are respectively installed on the two sliding plates 7. A fixator 10 is provided on the upper clamping plate 11. A rubber pad 21 is provided at the bottom end of the fixator 10. Fixing strips 20 are provided on both sides of the rubber pad 21. The fixing strips 20 are fixed on one side of the upper clamping plate 11. A limiting rod 22 is installed on the fixing strip 20. Since the limiting rod 22 is provided, it can play a role in limiting and assisting in fixing the upper clamping plate 11 and the lower clamping plate 23, and improves the stability.

[0022] Moving clamping columns 9 are provided in the upper clamping plate 11 and the lower clamping plate 23. Clamping plates 24 are provided on both sides of the moving clamping columns 9. A rotating shaft 26 is installed in the clamping plates 24. A spring 25 is installed on one side of the rotating shaft 26. A pressing plate 8 is installed on one side of the spring 25. The end of the spring 25 is fixed in a slot hole opened on the upper clamping plate 11. Both ends of the rotating shaft 26 are connected in the slot hole.

[0023] A support block 18 is installed on the operating table 14. A fixing block 15 is installed on the support block 18. A motor 16 is provided on one side of the fixing block 15. One side of the motor 16 is installed on the mounting column 17. Since the fixing block 15 is provided, it is convenient for the stable installation of the structure and can improve the stability of the machining work. Since the mounting column 17 is provided on one side of the motor 16, the motor 16 can be prevented from falling off and the stability of the motor 16 is improved.

[0024] Support legs 19 are installed below the operating table 14. The number of support legs 19 is four and they are respectively installed at the four corners of the operating table 14. Since the support legs 19 are installed around the operating table 14, accidental movement during machining work can be prevented and the safety during work is improved.

[0025] The working principle of the new type is as follows: When carrying out disassembly and assembly work, only need to open the limit rod 22 installed on the fixing strip 20, and then press the pressing plate 8 inward, so that the clamping plate 24 rotates around the rotating shaft 26, making one end of the clamping plate 24 disengage from the moving clamping column 9. Then, just move the moving clamping column 9 to separate the upper clamping plate 11 and the lower clamping plate 23, and the inside of the upper clamping plate 11 and the lower clamping plate 23 can be cleaned. When carrying out the assembly work, press the moving clamping column 9, and the moving clamping column 9 will move downward. At the same time, since the clamping plate 24 is close to the moving clamping column 9, the clamping plate 24 will deflect to both sides. Since the deflection of the clamping plate 24 to both sides will squeeze the spring 25 at the other end of the clamping plate 24 to generate elastic force, the elastic force will reset the clamping plate 24. Such repeated movement is carried out. When the moving clamping column 9 moves to the installation position, the clamping plate 24 will move into the groove of the moving clamping column 9 for fixation.

[0026] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0027] The above has made a detailed description of the preferred embodiment of this patent, but this patent is not limited to the above embodiment. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can also be made without departing from the purpose of this patent.
