Description

A crankshaft surface flushing box

technical field

The invention relates to a crankshaft flushing box, in particular to a crankshaft surface flushing box.

Background technique

We know that the crankshaft is one of the important parts for transmitting power in the engine. In addition to strict requirements on mechanical properties, it also has high requirements on cleanliness and particle size. In order to meet this requirement, most of the crankshafts are supported by V-shaped blocks in the flushing box at present, and the crankshaft is manually turned over and scrubbed with a brush dipped in flushing liquid. This method is not only labor-intensive and time-consuming, but also has a poor flushing effect.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a crankshaft surface flushing box with simple structure, labor-saving and time-saving operation, good flushing effect, high efficiency, good effect and low cost.

The technical scheme adopted by the present invention to solve the above-mentioned technical problems is: a crankshaft surface flushing box, which includes a box body, a crankshaft support rolling device, and a shower, and is characterized in that: the box body is a cuboid, and the lower part is funnel-shaped. Placed on the outriggers, beams are welded on both sides of the inner wall of the box, and grooved beams arranged in parallel are welded and fixed between the beams; the crankshaft supporting and rolling device includes two pairs of rollers, brackets, grooved supports, and two grooves The brackets are respectively welded on two grooved beams, and the brackets are fixed on the grooved bearings through bolts and nuts. The paired rollers are mounted on the brackets through the axles and bearings. The main journals at both ends of the crankshaft are placed on two pairs of between the scroll wheels. Turn the crankshaft by hand and flush the surface of the crankshaft through the shower.

According to the present invention, the roller and the outer ring of the bearing are fixed by a retaining ring, and the wheel shaft passes through the through holes provided on the inner ring of the bearing, the spacer and the support, and is pressed with a nut.

The sprayer of the present invention includes a liquid inlet pipe, a liquid-distributing horizontal pipe, and a spray hose. Several spray hoses. The output end of the spray hose can spray and wash the manually rotated crankshaft, and can use the liquid flow sprayed from the spray hose to manually scrub the crankshaft with a hair brush.

The bottom end of the box body of the present invention is also provided with a liquid discharge pipe. The dirty liquid after flushing is discharged through the drain pipe. the

When the present invention is used, the liquid inlet pipe is connected, the crankshaft is manually rotated, and the surface of the crankshaft is washed through the spray hose. And the liquid flow sprayed by the spray hose can be borrowed to manually scrub the crankshaft with a brush. Compared with the prior art, the present invention has reasonable structure, easy assembly, convenient operation and use, labor-saving and time-saving, high flushing efficiency, good flushing effect, manual rotation, and no power required. Especially suitable for manual washing of crankshaft surface.

Detailed ways

It can be seen from Fig. 1 and Fig. 2 that a crankshaft surface flushing box includes a box body 4, a crankshaft supporting and rolling device, a sprayer and the like. The box body 4 is a cuboid and is formed by welding box plates. The lower part is funnel-shaped and placed on the support leg 1. A crossbeam 2 is welded on both sides of the inner wall of the box body 4, and channel beams 3 arranged in parallel are welded and fixed between the two beams, and the crankshaft support rolling device is installed on the two channel beams 3. The crankshaft supporting and rolling device includes two pairs of rollers 10, a bracket 16, and a grooved support 19, and the two grooved bearings 19 are respectively welded on two grooved beams 3, and the bracket 16 is fixed by bolts 17 and nuts 18. On the grooved support 19 , the paired rollers 10 are mounted on the bracket 16 through the axle 13 and the bearing 11 . Specifically, described roller 10 and bearing 11 outer ring are fixed by retaining ring 15, and wheel shaft 13 passes through the through hole that is provided with on bearing 11 inner ring, spacer 12 and support 16, and compresses with nut 14. The main journals at both ends of the crankshaft 6 are placed between the two pairs of rollers 10 . Rotate the crankshaft 6 manually, and wash the surface of the crankshaft through the sprayer.

The sprayer of the present invention includes a liquid inlet pipe 9, a liquid-separating horizontal pipe 5, and a spray hose 8. The liquid-inlet pipe 9 is installed on one side of the box body 4, and it is connected to the liquid-separating horizontal pipe 5 in the box body 4. , several spraying hoses 8 are connected on the liquid-separating horizontal pipe 5 . Spray hose 8 output ends can spray and rinse the crankshaft 6 that is manually rotated, and can borrow the liquid flow that spray hose sprays, and manually brush the crankshaft with a hairbrush. The spray hose 8 is connected with the threaded joint on the horizontal pipe 5 through the nut 7 .

The spray hose of the present invention has bendability, and the output end of the spray hose can be manually moved to flush the required flushing position of the positive crankshaft.

The bottom end of the box body 4 of the present invention is also provided with a liquid discharge pipe 20 . The dirty liquid is discharged through the drain pipe 20 after flushing. the

When the present invention is used, the liquid inlet pipe is connected, the crankshaft is manually rotated, and the surface of the crankshaft is washed through the spray hose. And the liquid flow sprayed by the spray hose can be borrowed to manually scrub the crankshaft with a brush. The utility model has the advantages of reasonable structure, easy assembly, convenient operation and use, labor-saving and time-saving, high flushing efficiency, good flushing effect, manual rotation, and no power required.
