Description

Technical Field

[0001] The utility model belongs to the technical field of crankshaft processing equipment, and particularly relates to a compressor crankshaft inclined hole processing equipment. 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 periodically changing gas inertia force, and the reciprocating inertia force, which causes the crankshaft to bear the action of bending and torsional loads. Therefore, it is required that the crankshaft has sufficient strength and stiffness, 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 open inclined holes on the crankshaft. When traditional drilling equipment processes inclined holes, generally, the crankshaft is inclined and fixed on the processing platform of the drilling equipment, and the drilling equipment is manually operated to process the inclined holes of the crankshaft. When processing the crankshaft by the above method, due to large differences among individuals, there are large errors in the inclination angle of the crankshaft, and only one crankshaft can be processed at a time, resulting in low processing efficiency of the crankshaft inclined holes and high labor intensity of workers.

Simultaneously, the third threaded connection block 71 pushes the sliding sleeve 63 to slide within the sliding groove. A limit mechanism limits the travel of the sliding sleeve 63, facilitating the drill bit 66 to machine the crankshaft's inclined hole. The microprocessor of the present utility model is connected to two limit switches 77. The third threaded connection block 71 of the present invention is provided with a through mounting hole 74, and the limit mounting rod 92 is installed in the mounting hole 74 and moves synchronously with the third threaded connection block 71. A distance abutment block 76 is respectively provided at both ends of the limit mounting rod 92, and a pair of limit switches 77 are provided on the drilling mounting seat 61.

When the third threaded connection block 71 moves to the nearest end, the other distance abutment block 76 abuts against the limit switch 77 on the same side, and the limit switch 77 transmits the detected electrical signal to the microprocessor, which controls the fourth servo motor 72 to stop rotating, thereby limiting the moving distance of the sliding sleeve 63, thereby facilitating drilling of the crankshaft 4.

[0135] In the present utility model, the guiding mechanism is installed on the frame 1 and connected to the mounting seat 7, so as to guide the moving direction of the mounting seat 7. The bearing seat D86 and the fixed seat 87 are installed on the frame 1. During use, the sixth servo motor 90 drives the fourth threaded block 89 to rotate through the fourth coupling 102, so that the fourth threaded block 89 moves along the axis of the fourth threaded rod 88 as the fourth threaded rod 88 rotates. Thus, the fourth threaded rod 88 pushes the mounting seat 7 to slide on the guiding mechanism, facilitating the adjustment of the height of the mounting seat 7 on the frame 1 for machining the inclined hole of the crankshaft.

[0136] In the present utility model, the fourth threaded block 89 is provided with a threaded hole adapted to the fourth threaded rod 88, and the fourth threaded rod 88 is threadedly connected to the threaded hole.

The counterweight block 94 is connected to the mounting seat 7 through two groups of counterweight connection mechanisms, so that the center of gravity of the mounting seat 7 is on the lifting mechanism 6. In the present utility model, one end of the pull rope 95 is connected to the first lifting lug 103, and the other end sequentially passes through the two pulleys 93 and is connected to the second lifting lug 104. When in use, as the mounting seat 7 moves up and down on the frame 1, the mounting seat 7 pulls the counterweight block 94 to move up and down in the relief groove 91 through the pull rope 95, so that the mounting seat 7 is kept stable by the counterweight block 94.
