Abstract
The utility model discloses a rim knurling device which comprises a machine body, a spindle and an operation platform, wherein the spindle is driven by a variable transmission box; the operation platform is connected with the spindle; a hob head is arranged on the machine body on one side of the axis of the spindle through a guide rail; and a feeding driving hammer is connected with the hob head. Compared with the prior art, the rim knurling device solves the problem of different depths of patterns caused by performing knurling processing on the rim.
Description
Technical field
The utility model relates to machining equipment manufacturing technology field, especially a kind of equipment that carries out annular knurl processing for motor vehicle wheel rim surface.
Background technology
For increasing the coefficient of friction between wheel and the tire, increasing friction force, to overcome and to prevent relative sliding between tire and the wheel, some wheel rim, especially the engineering truck wheel rim of operation under not enough at tire pressure or the abominable working environment, and large-scale wheel rim often need to be at its surface extrusion decorative pattern with the position of tire crimping.The width of this decorative pattern, the degree of depth and spacing have certain requirement.The processing technology of present this decorative pattern is to adopt wheeled knurling tool on lathe rotary work piece to be carried out rolling extrusion to finish, and the processing of this large-scale wheel rim decorative pattern is normally finished at vertical machine, wheel rim is installed on the machine tool chief axis, knurling tool is contained on the tool slide, during process operation, start machine tool chief axis and drive the wheel rim rotation, then knurling tool is pressed to the surperficial certain depth that wheel rim need to be processed, make the rotation wheel rim under the extruding of knurling tool, form decorative pattern.
There is following point in above-mentioned vertical machine when being used for processing wheel rim decorative pattern: because the wheel rim clamping can depart from the centre of gyration, since clamping wheel rim can exist circularity to change or distortion, so that roll extrusion point can produce circular runout, in the situation of amount of feeding homeostasis, the degree of depth that knurling tool is pressed into surface of the work will be neglected deeply suddenly shallow, causes the decorative pattern that processes deep mixed.
The utility model content
Problem to be solved in the utility model provides a kind of rim serrations equipment, and it can solve the decorative pattern that processing obtains to rim serrations and have deep mixed problem.
In order to address the above problem, the technical solution of the utility model is: this rim serrations equipment, the main shaft that comprises fuselage, drives by change gearbox and be connected to workbench on the main shaft, described fuselage is equipped with hob head in a side of described main-shaft axis by guide rail, and described hob head is connected with one by drag-line and drag-line leading block and drives described hob head towards the weight of described main-shaft axis direction feeding.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:
Can allow hob head provide the pressure of a homeostasis according to extruding degree of depth needs to knurling tool, rather than the depth of cut of a homeostasis, basically identical to guarantee the pattern depth that extrudes.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Rim serrations equipment shown in Figure 1, it has the fuselage 1 of a support body form, below fuselage 1, be connected with change gearbox 5 and the motor 4 that is connected with change gearbox 5 power shafts, the output shaft of change gearbox 5 is connected with the main shaft 6 of this wheel rim annular knurl equipment, the upper end of main shaft 6 is fixedly connected with workbench 7, fuselage 1 side of axis above main shaft 6 is equipped with guide rail 2,2 are equipped with hob head 8 on the guide rail, knurling tool 9 is housed on the hob head 8, and hob head 8 is connected with one by drag-line 10 and drag-line leading block 11 and drives hob head 8 towards the weight 3 of main-shaft axis direction feeding.This wheel rim annular knurl equipment is when work, can allow 8 pairs of knurling tools 9 of hob head provide a homeostasis and suitable pressure by the weight of regulating weight 3, so that 9 pairs of knurling tools are installed in the feeding pressure of the homeostasis of wheel rim 10 maintenances on the workbench 7, even since wheel rim 10 clampings can depart from the centre of gyration or owing to clamping the circularity variation that exists of rim deformation cause the roll extrusion point and can produce circular runout, can not affect the variation of 9 pairs of wheel rim 10 pressure of knurling tool, the problem that the decorative pattern that can not occur processing is deep mixed yet.
Claims (1)
1. rim serrations equipment, the main shaft that comprises fuselage, drives by change gearbox and be connected to workbench on the main shaft, it is characterized in that: described fuselage is equipped with hob head in a side of described main-shaft axis by guide rail, and described hob head is connected with one by drag-line and drag-line leading block and drives described hob head towards the weight of described main-shaft axis direction feeding.
