Detailed description of the invention

As shown in Figure 1, the utility model discloses a kind of refrigerator compressor crankshaft centering machine, comprise: base 1, back seat 2, fixed muffle 3, hold-down bolt 4, vertical rod 5, pressing plate 6, clamping screw 7, guide rail 8, chute 9, slide unit 10, riser 11, screw mandrel 12, main shaft mount pad 13, main shaft 14, drill bit 15, motor 16, cushion block 17, a back seat 2 is vertically installed by bolt in rear end on described base 1 upper surface, on the front end face of described back seat 2, level welds a fixed muffle 3, the mode that described fixed muffle 3 is threaded connection vertically installs a hold-down bolt 4, and the screw rod of hold-down bolt 4 extend into fixed muffle 3 inside, a vertical rod 5 is vertically welded at middle part on described base 1 upper surface, in described vertical rod 5, level cover has a pressing plate 6, described pressing plate 6 is slidably connected with vertical rod 5, the mode level that described pressing plate 6 is threaded connection installs a clamping screw 7, the screw rod of described clamping screw 7 contacts with the periphery of vertical rod 5 through pressing plate 6, left and right two parts on described base 1 upper surface do not set firmly a guide rail 8, and each guide rail 8 all arranges a chute 9, described chute 9 is slidably connected with guide rail 8, described slide unit 10 is welded on the upper surface of two chutes 9 in left and right, the front end face of described base 1 vertically welds a riser 11, described riser 11 installs a screw mandrel 12 by bearing level, the mode that the rear end of described screw mandrel 12 is threaded connection is connected with slide unit 10, the upper surface of described slide unit 10 vertically welds a main shaft mount pad 13, described main shaft mount pad 13 installs a main shaft 14 by bearing level, a drill bit 15 is installed in the rear end of described main shaft 14, described slide unit 10 sets firmly a motor 16, the output shaft of described motor 16 and the front end of main shaft 14 affixed, a cushion block 17 is welded at middle part on described base 1 upper surface, described cushion block 17 is in the left side of vertical rod 5, and the position of cushion block 17 is immediately below pressing plate 6 left side.

The front end of described screw mandrel 12 sets firmly a handwheel 18.

The utility model implements like this: be inserted into the rear end of refrigerator compressor crankshaft in fixed muffle 3, move downward to make the screw rod of hold-down bolt 4 by rotatably compressing bolt 4, hold-down bolt 4 gradually near and contact with the back end circumference face of bent axle, further rotate hold-down bolt 4, till the rear end of refrigerator compressor crankshaft is pressed on fixed muffle 3 inside by the screw rod of hold-down bolt 4, the middle part of refrigerator compressor crankshaft is placed on cushion block 17, then pressing plate 6 is glided along vertical rod 5, till bent axle is pressed on cushion block 17 by pressing plate 6, then rotational lock bolt 7 with on the periphery making the screw rod of clamping screw 7 be pressed on vertical rod 5 further till pressing plate 6 is pressed abd fixed in vertical rod 5, starter motor 16, motor 16 drives main shaft 14 to rotate, the rotation of main shaft 14 drives drill bit 15 to rotate, processing staff only need by handwheel 18 rotary screw 12, because screw mandrel 12 can only rotate relative to riser 11, and can not move forward and backward, therefore slide unit 10 can move backward relative to screw mandrel 12, such slide unit 10 drive main shaft mount pads 13 move backward, main shaft mount pad 13 drives drill bit 15 to contact with refrigerator compressor crankshaft front end gradually backward by main shaft 14, in the process of moving after drill bit 15 is further like this, complete the processing to centre bore, use more convenient, and due to processing process in refrigerator compressor crankshaft can not shake, therefore centre bore processing effect is good, in addition, owing to eliminating servostabilization refrigerator compressor crankshaft, labour intensity significantly reduces, very large saves manpower and muscle power, saving of work and time.

Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model; Therefore, although this description has been described in detail the utility model with reference to each above-mentioned embodiment, those of ordinary skill in the art should be appreciated that and still can modify to the utility model or equivalent replacement; And all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
