Abstract

The utility model provides a machine of knurling processing to cylindrical work pieces, which comprises a bed piece, a headstock, a main shaft, a knurling wheel carrier, a knurl wheel component, feed screws, etc., wherein, the knurling wheel carrier is installed on the bed whose lower end is connected with the feed screw; a centering wheel and the knurl wheel are symmetrically installed on a device which simultaneously gathers and releases to form the knurl wheel component, the component is installed on the knurling wheel carrier, the axis of the knurl wheel component coincides with the axis of the main shaft, the knurling element is parceled between the knurl wheel and the centering wheel, which makes the knurling element free from the function of cross force. The utility model has advantages of convenient clamping and increased efficiency.

Description

Knurling machine

The utility model is to be exclusively used in the machine that garden cylindrical parts surface knurling is used.

Present annular knurl processing is all carried out on engine lathe, knurling tool is contained on the knife rest of lathe, annular knurl spare one end is clipped on the scroll chuck of lathe, the other end holds out against with thimble, to be contained in knurling tool on the knife rest then and be squeezed in the end at annular knurl position, start lathe and make the rotation of annular knurl spare, and make knurling tool go to the other end, make annular knurl spare surface obtain needed decorative pattern on the annular knurl spare owing to knurling tool is squeezed in from an end that needs annular knurl.The weak point of this processing method is the effect that annular knurl spare is subjected to cross force, therefore must clamp with scroll chuck by an end, and the other end holds out against with thimble, the required clamping time is long, and want reciprocal feed just to process several times, work efficiency is low, and is not suitable for machining slender shaft.

In view of above-mentioned this situation, the purpose of this utility model provides a kind of convenient mounting and clamping, work efficiency height, annular knurl and adds man-hour annular knurl spare and be not subjected to the edge knurling machine of cross force effect.

Task of the present utility model is achieved through the following technical solutions, motor passes through belt pulley, belt drives the main axis rotation in the headstock, the output of main shaft has one to make the liquid flower part clamping device concentric with main shaft---scroll chuck, the main shaft output is similar on its structure such as the engine lathe, one end of annular knurl spare is clamped in the clamping device of main shaft output, the knurled wheel of garden cylindricality and the centering wheel of garden cylindricality are pressed on an annular knurl spare annular knurl end partly simultaneously, the rotation of (this moment, annular knurl spare wrapped in the centre of knurled wheel and centering wheel three-wheel) main shaft drives annular knurl spare and rotates together, rotate feed screw then, length feed is to the length that needs annular knurl on annular knurl spare to make knurled wheel and centering wheel, and the clutch of bevel gear realizes in bevel gear that the turning to of feed screw installed by two opposites on the power shaft and the changement.

Main mounting teeth wheel decelerator in the headstock, decelerator is by two axles and several gear is formed, and one is power shaft, and its input is equipped with the pagoda belt pulley, and another root is output shaft (being main shaft); Several speed reducing ratio to gear are fit to the linear velocity in the outer garden of annular knurl spare of different-diameter respectively in 15～20 meters/minute scopes.

The annular knurl wheel carrier links to each other with dovetail groove with dovetail with lathe bed; be shaped on dovetail on the annular knurl wheel carrier; be shaped on dovetail groove on the lathe bed; use little matched in clearance between dovetail and dovetail groove; annular knurl wheel carrier lower end links to each other with feed screw; knurled wheel on the knurled wheel assembly is parallel to each other with three core wheel lines of centering wheel; and be installed in symmetrically on the scroll chuck that can draw in simultaneously or decontrol; the knurled wheel assembly is installed on the annular knurl wheel carrier, and the axial line (axial line of knurled wheel assembly) and the axial line of main shaft of the Cylinder that three core wheel lines parallel to each other that will keep knurled wheel and centering to take turns during installation are formed coincide.The axial location of knurled wheel and centering wheel staggers mutually, and both are end to end, during feeding the centering wheel preceding, knurled wheel after.

Utilize this edge knurling machine to carry out annular knurl processing, compare with carry out annular knurl processing usually on lathe, its work efficiency can improve more than 6 times.

Accompanying drawing 1 is the structural representation of the utility model embodiment, 1 lathe bed among the figure; 2 annular knurl wheel carriers; 3 knurled wheel sub-assemblies; 4 feed screws; 5 clamping devices; 6 headstocks; 7 main shafts (output shaft); 8 power shafts; 9 belt pulleys; 10 feed screws commutation transmission mechanism; 11 motor; 12 supports; 13 cooling devices.

Accompanying drawing 2 is knurled wheel and the symmetrical schematic diagram that is installed on the scroll chuck of centering wheel.Among the figure: 1 centering wheel; 2 knurled wheels (during hatching knurling) or centering wheel (during straight knurling) 3 knurled wheels; 4 scroll chucks.(accompanying drawing 2 is that A in the accompanying drawing 1 is to view)

The utility model is proven, and cost is low, and work efficiency height, annular knurl spare are not subjected to cross force Effect, applicable to the processing of the annular knurl of slender axles. But its lathe bed machine tool dragging plate substitutes, the annular knurl wheel carrier is installed on the planker, and the knurled wheel assembly can be taken turns on three pawls that are installed in scroll chuck with knurled wheel and centering and be consisted of, thereby can realize that knurled wheel and centering wheel push simultaneously to annular knurl spare, but be not subjected to the effect of cross force, support can weld with angle steel.
