Description

Technical Field

[0001] The utility model belongs to the technical field of crankshaft processing equipment, and particularly relates to a moving platform for drilling. Background Technique

[0002] The crankshaft is the most important component in a compressor. The crankshaft is jointly affected by the centrifugal force of the rotating mass, the periodic gas inertia force, and the reciprocating inertia force, which causes the crankshaft to bear the action of bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and stiffness, and the journal surface needs to be wear-resistant, work evenly, and have good balance.

[0003] During the processing of the crankshaft, it is often necessary to perform drilling operations on it to meet the usage requirements of the crankshaft. When traditional drilling equipment drills holes, the crankshaft is generally directly fixed on the drill table, and the position between the crankshaft and the drill bit is adjusted manually. Due to large differences among individuals during the manual adjustment process, there will be large errors when workers adjust the position of the crankshaft, thus affecting the processing accuracy of the inclined holes of the crankshaft.

During use, by inputting a preset value into the microprocessor, the microprocessor controls the first servo motor 12 to rotate. When the sliding platform 2 moves to the preset value, the microprocessor controls the first servo motor 12 to stop running, thereby facilitating the adjustment of the position of the sliding platform 2. When the utility model adjusts the sliding seat 3, a preset value is input into the microprocessor, and the microprocessor controls the second servo motor 25 to operate. The second servo motor 25 drives the second threaded rod 23 to rotate through a transmission mechanism, thereby driving the sliding seat 3 to move. When the sliding seat 3 moves to the preset value, the microprocessor controls the second servo motor 25 to stop running, thereby facilitating the adjustment of the position of the sliding seat 3 and facilitating the precise control of the drilling position of the crankshaft.

[0098] The microprocessor used in the utility model is preferably an AT91RM9200 type microprocessor.
