The specific embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Figure 1 to Figure 3, a kind of device that axis products is carried out to segmented annular knurl, the bracing frame 10 that comprises " recessed " font, the interior level of bracing frame 10 is provided with two parallel the first knurled wheel 20 and the second knurled wheels 30, axis products 40 is horizontally set between the first knurled wheel 20 and the second knurled wheel 30 on bracing frame to 10, concrete is rotatably connected on the two ends of axis products 40 respectively on the two side of bracing frame 10, axis products 40 two ends can be connected on the two side of bracing frame 10 by connecting scroll chuck 70, bearing fixed seat 80 is installed on the two side of bracing frame 10, each scroll chuck 70 is rotationally connected with bearing fixed seat 80, thereby can make axis products 40 rotate on bracing frame 10.The first knurled wheel 20 and the second knurled wheel 30 in the present invention include rotating shaft 21, are axially disposed on successively at least three annular knurl gear wheels 22 in rotating shaft 21.Each annular knurl gear wheel 22 can be fixedly installed in rotating shaft 21, also can endwisely slip and be arranged in rotating shaft 21, to regulate the spacing between each annular knurl gear wheel 22, meets different segmented annular knurl requirements.The first knurled wheel 20 and the second knurled wheel 30 by segmented in the present invention push from axis products 40 both sides simultaneously, can the disposable annular knurl that processes segmented on axis products 40, greatly improved annular knurl efficiency; Because the first knurled wheel 20 and the second knurled wheel 30 push from axis products 40 both sides simultaneously, avoided axis products 40 one directions stressed, prevent axis products 40 bendings, greatly improved the crudy of axis products 40.
Preferably, the second knurled wheel 30 in the present invention can vertically move along the sidewall of bracing frame 10, specifically can on the two side of bracing frame 10, all establish the chute longitudinally 11 that runs through both sides, in chute 11, be provided with the support 50 of the rotating shaft 21 of Height Adjustable support the second knurled wheel 30.Concrete, the end of support 50 has the arc groove 51 with rotating shaft 21 laminatings, on the lateral wall of support 50, near groove 51 places, the axially movable postive stop baffle 52 of restriction rotating shaft 21 is set, postive stop baffle 52 is " L " font, the right-angle side longitudinally of postive stop baffle 52 is resisted against on the end of rotating shaft 21, make to leave distance H 1 between the right-angle side of level of postive stop baffle 52 and groove 51 bottoms, this distance H 1 can make the driving-belt of motor pass through, to drive the rotating shaft 21 of the second knurled wheel 30 to rotate.Arc groove 51 on support 50 can limit rotating shaft 21 radial rollings of the second knurled wheel 30, postive stop baffle 52 can prevent that rotating shaft 21 from moving axially, this structure can guarantee that the second knurled wheel 30 can not produce skew when rotating, and has guaranteed the effect to axis products 40 annular knurls.
Further, support 50 in the present invention comprises the first sleeve pipe 53 and socket the second sleeve pipe 54 within it, the second sleeve pipe 54 drives it in the interior lifting of the first sleeve pipe 53 by hydraulic jack 60, groove 51 is arranged on to the end of the second sleeve pipe 54, and postive stop baffle 52 is arranged on the second sleeve pipe 54 sidewalls.In the present invention, utilize Height Adjustable support 50 to regulate the height of the second knurled wheel 30 on bracing frame 10, thereby regulate the distance between the second knurled wheel 30 and the first knurled wheel 20, make the axis products 40 that this distance can accommodating different-diameter, be convenient to the axis products 40 of different-diameter to carry out annular knurl processing, practicality is higher.
When utilizing device of the present invention to carry out segmented annular knurl to axis products 40, first the first knurled wheel 20 is installed on bracing frame 10, the annular knurl gear wheel 22 of again outer wall of axis products 40 being fitted on the first knurled wheel 20 is installed on bracing frame 10, according to the height of mounted axis products 40, regulate the setting height(from bottom) of the second knurled wheel 30, and the annular knurl gear wheel 22 that makes the second knurled wheel 30 is close to the outer wall of axis products 40, utilize motor connection for transmission band to drive rotating shaft 21 rotating in same directions of the first knurled wheel 20 and the second knurled wheel 30 simultaneously, thereby utilize each annular knurl gear wheel 22 on the outer wall of axis products, to suppress the annular knurl of segmented, after machining, reduce the height of the second knurled wheel 30, can easily the axis products processing 40 be taken out from bracing frame 10, simple to operation.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on description, must determine technical scope according to claim scope.
