[0023] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0024] Please refer to Figures 1-4 , a fixing bracket for engine crankshaft processing, including a placing table 1, an auxiliary extraction mechanism 2 and a placing mechanism 4. An auxiliary extraction mechanism 2 is installed at the outer end of the placing table 1. The auxiliary extraction mechanism 2 includes a support plate 201, a round shaft 202, a buffer frame 203 and a return spring 204. The support plate 201 is installed at one end of the placing table 1. A round shaft 202 is installed at one end of the placing table 1. A buffer frame 203 is installed through one end of the round shaft 202. A return spring 204 is installed at the lower side of the front end of the buffer frame 203. The buffer frame 203 installed in the device can rotate through the round shaft 202, and the height can be buffered by the return spring 204 at the other end during rotation. The processed engine crankshaft can be placed, which is convenient for extraction.

[0025] Please refer to Figures 1-4 , a fixing bracket for engine crankshaft processing. A card slot 3 is opened at the upper end of the placing table 1. A placing mechanism 4 is installed at the upper end of the card slot 3. The placing mechanism 4 includes a placing frame 401, a connection hole 402 and an adjusting clamping rod 403. The placing frame 401 is installed at the upper end of the placing table 1. A connection hole 402 is opened at one end of the placing frame 401. An adjusting clamping rod 403 is installed at one end of the connection hole 402. The adjusting clamping rod 403 installed in the device can fix the engine crankshaft placed on the placing frame 401, and multiple crankshafts can be placed and processed while being fixed.

[0026] Please refer to Figures 1-4, a fixed bracket for engine crankshaft processing. Stabilizing platforms 5 are installed at both left and right ends of the placement table 1. A placement groove 6 is provided at the upper end of the stabilizing platform 5. A hydraulic cylinder 7 is installed inside the placement groove 6. A lifting rod 8 is installed at the upper end of the hydraulic cylinder 7. A clamping frame 9 is installed at the upper end of the lifting rod 8. The clamping frame 9 forms a lifting structure with the placement table 1 through the lifting rod 8, and the clamping frame 9 is arranged opposite to the placement table 1. The installed clamping frame 9 in the device can be adjusted to different heights with the placement table 1 through the hydraulic cylinder 7, so as to adapt to the placement and fixation of crankshafts of different sizes for processing.

[0027] Working principle: When in use, the hydraulic cylinder 7 installed in the device can lift the upper clamping frame 9 through the lifting rod 8. After lifting, one end of the engine crankshaft to be processed is placed on the upper end of the placement frame 401 on the placement table 1.
