Abstract
The invention discloses a deburring method for a crankshaft for a refrigerator compressor, and capable of efficiently removing burrs and ensuring thorough deburring. According to the deburring method for the crankshaft for the refrigerator compressor, the crankshaft for the refrigerator compressor is made from a nodular cast iron material, and comprises a long shaft, an eccentric shaft and a counter weight, and the long shaft is connected with the eccentric shaft through the counter weight. The deburring method comprises the following steps: after oil holes are machined for the crankshaft for the refrigerator compressor, using a shot-blasting machine, aligning an ejection port of a blasting gun of the shot-blasting machine with the oil holes, and forming fixed-point injection for steel shots by the blasting gun of the shot-blasting machine, thus steel shots are injected into the oil holes.
Description
Technical field
The invention belongs to the technical field of freezer compressor Crankshaft Machining, the method concretely relating to the deburring of a kind of freezer compressor bent axle.
Background technology
On freezer compressor bent axle, distribution has oilhole. Oilhole has the length direction along bent axle to extend, and also has the radial direction along bent axle to extend. It should be noted that length direction is not limited to crankshaft center line direction, has along axis direction extension, also have the direction with axis angulation to extend. Such as, notification number is CN204755239U, the day for announcing is a kind of bent axle for freezer compressor disclosed in Chinese invention patent disclosed in 11 days November in 2015. Before, freezer compressor bent axle adopts carbon steel material to make, but, the freezer compressor bent axle being made up of this material easily causes fracture. To this, for improving the performance of freezer compressor bent axle, it adopts ductile cast iron material to make. But, at freezer compressor with, in bent axle mechanical processing process, easily forming burr in the both direction junction of oilhole. In the prior art, for removing burr, adopt reamer in manual work mode. This mode working performance is low, and cause burr to remove because of properties of materials not thorough yet, thus causing, freezer compressor is stuck to be scrapped.
Summary of the invention
The method that it is an object of the invention to provide the deburring of a kind of freezer compressor bent axle, it can remove burr efficiently, and ensure that burr is removed thoroughly.
For solving above-mentioned technical problem, the object of the present invention is achieved like this:
A kind of method of the deburring of freezer compressor bent axle, freezer compressor bent axle is made up of ductile cast iron material, and described freezer compressor bent axle includes major axis, balance weight and eccentric shaft, and major axis is connected with eccentric shaft by balance weight, comprises the following steps:
After freezer compressor bent axle completes roughing, oilhole being adopted compressed air shotblasting machine, make the jet of compressed air shotblasting machine spray gun and oilhole face, compressed air shotblasting machine spray gun forms fixed point injection shot, so that shot is injected in oilhole.
On the basis of such scheme and as the preferred version of such scheme: the diameter of described shot is 0.2mm.
The present invention highlights and useful having the technical effect that compared to existing technology
The method of the deburring of the freezer compressor bent axle of the present invention, owing to adopting the shot that compressed air shotblasting machine is sprayed by high pressure to make a return journey the burr in oil removing hole, removes burr effective.Furthermore, utilize compressed air shotblasting machine spray gun and oilhole to form the injection of point-to-point fixed-point type so that the shot that compressed air shotblasting machine spray gun ejects precisely is injected in oilhole, greatly increase deburring efficiency, and ensure that the burr in oilhole is removed thoroughly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the freezer compressor bent axle of the present invention.
Fig. 2 is the structural representation of the freezer compressor bent axle of the present invention.
Fig. 3 is the process chart of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described, referring to Fig. 1 Fig. 2;
The method that this gives the deburring of a kind of freezer compressor bent axle, comprises the following steps:
A) machining of oil hole step, it is the part steps in bent axle roughing (including car, milling, brill), to complete machining of oil hole on freezer compressor bent axle. Freezer compressor bent axle is made up of ductile cast iron material. As shown in FIG., described freezer compressor bent axle includes major axis 1, eccentric shaft 2 and balance weight 3, and wherein, major axis is also referred to as main shaft, and eccentric shaft is also referred to as crank throw, and major axis is connected with crank throw by balance weight. Oil circuit includes the oilhole radially extended along freezer compressor bent axle.
B) deburring step: after machining of oil hole step completes, adopts compressed air shotblasting machine, makes the jet of compressed air shotblasting machine spray gun and oilhole face, and compressed air shotblasting machine spray gun forms fixed point injection shot, so that shot is injected in oilhole. As shown in FIG., oilhole includes the oilhole 1 and the oilhole 25 that are located on major axis 1, and is located at the oilhole 36 on eccentric shaft 2. In the present embodiment, adopt three compressed air shotblasting machine spray guns to face with oilhole one, oilhole two and oilhole three respectively, make the shot that each compressed air shotblasting machine spray gun ejects inject oilhole one, oilhole two and oilhole three respectively, to complete deburring. It is of course also possible to adopt a compressed air shotblasting machine spray gun, sequentially, alignment oilhole one, oilhole two and oilhole three, so that shot is injected into oilhole one, oilhole two and oilhole three, to complete deburring.
In the present embodiment, the diameter of described shot is 0.2mm.
The method of the deburring of this freezer compressor bent axle, owing to adopting the shot that sprays of compressed air shotblasting machine to make a return journey the burr in oil removing hole, removes burr effective. Furthermore, utilize compressed air shotblasting machine spray gun and oilhole to form the injection of point-to-point fixed-point type so that the shot that compressed air shotblasting machine spray gun ejects precisely is injected in oilhole, greatly increase deburring efficiency, and ensure that the burr in oilhole is removed thoroughly.
Above-described embodiment is only presently preferred embodiments of the present invention, not limits the scope of the invention according to this, therefore: the equivalence change that all structures under this invention, shape, principle are done, all should be covered by within protection scope of the present invention.
