The kinematic accuracy and dynamic accuracy of the main rotating wheel are improved by the main rotating wheel assembly, and the service life of the assembly is improved by 13 times, and the rotating wheel can be dismounted conveniently, thereby being capable of realizing replacement, greatly improving the utilization rate of equipment and increasing economic benefit.
Description
Technical field
The utility model relates to a kind of spoke of vehicle wheel spinning machine master spinning roller assembly.
Background technology
The main on the one hand cylinder body 11 that revolves of existing spoke of vehicle wheel spinning machine master spinning roller is fixed, and main revolving is equipped with an oil cylinder in the cylinder 12.When oilhole 13 oil-feeds, the master is revolved cylinder 12 to left movement, oilhole 14 oil returns; When oilhole 14 oil-feeds, the master is revolved cylinder and is moved right oilhole 13 oil returns.The main cylinder 12 that revolves is called " interior motion " like this in main 15 li slips of copper sheathing of revolving cylinder body 11 inwalls.The shortcoming of this structure is: the one, and copper sheathing 15 (sliding bearing) break-out material problem, the 2nd, the main crack of revolving between cylinder 12 bodies and the copper sheathing 15 can not be adjusted, the 3rd, this gap becomes big through long-time wearing and tearing, rotate when revolving cylinder 12 linear reciprocating motions for preventing to lead, and the gathering sill yielding (be commonly called as and roll key) in feather key 16 that is provided with and the copper sheathing 15, destroy guiding, beat when causing spinning roller work, even can't work.
Bearing 171,172,173 heatings damaged when on the other hand, the original structure master was revolved cylinder 12 work.Main spinning roller 18 on the spinning roller axle 20 is contained on bearing chamber 19 outer walls, has limited the size of bearing chamber 19, can only use the ting model bearing, overload operation during spinning, and heating annealing, only have two months service life.So both do not satisfied the production needs, maintenance cost is also high.Change spinning roller in addition at every turn and the spinning roller assembly need be laid down just and can carry out, time-consuming, influence utilization rate of equipment and installations.(see figure 1)
The utility model content
At the shortcoming that above-mentioned prior art exists, the long-pending experience of being engaged in this area work for many years of the inventor through feasibility study repeatedly, gets generation of the present utility model eventually; The utility model provides a kind of spoke of vehicle wheel spinning machine master spinning roller assembly.
The technical solution adopted in the utility model is: a kind of spoke of vehicle wheel spinning machine master spinning roller assembly, the master revolves cylinder and main revolving between the cylinder body fixedly becomes one, main rotary cylinder piston bar is fixed on the piston rod fixed head that is installed on guide-track groove one end, the master is revolved the cylinder body and is slided in guide-track groove by oil cylinder, and guide-track groove and main revolving are provided with the adjustment bolt between the cylinder body; Main spinning roller is installed in the outer spinning roller axle head position of bearing chamber.
Above-mentioned guide rail is a dovetail guide, and the master is revolved the cylinder body and also made dovetail face, angle 55 degree.
Above-mentioned guide rail has carried out laminating processing.
Above-mentioned guide-track groove and main revolving also are provided with liner plate between the cylinder body.
The utlity model has following advantage: the utility model has improved the kinematic accuracy and the dynamic accuracy of main spinning roller, and has improved 13 times of service lifes, and the spinning roller dismounting is very convenient, can realize quick change, improves utilization rate of equipment and installations greatly, has increased economic benefit.
The utility model is described in further detail for following drawings and the specific embodiments.
Description of drawings
Fig. 1 is existing spoke of vehicle wheel spinning machine master spinning roller assembly structure;
Fig. 2 is the utility model spoke of vehicle wheel spinning machine master spinning roller assembly;
Fig. 3 is that the A-A of Fig. 2 is to side view.
The specific embodiment
As shown in Figures 2 and 3, the utility model spoke of vehicle wheel spinning machine master spinning roller assembly, the improvement technical scheme is: 1, the master is revolved cylinder 21 and is led to revolve between the cylinder body 22 and fixedly becomes one, main rotary cylinder piston bar 23 is fixed on the piston rod fixed head 25 that is installed on guide-track groove 24 1 ends, the master is revolved cylinder body 22 and is slided in guide-track groove 24 by oil cylinder, is called " outer motion ".In order to strengthen the main cylinder integral rigidity that revolves, master revolved cylinder 21 revolve cylinder body 22 and join together with leading, increased cast steel guide-track groove 24, dovetail guide 26 simultaneously.The main cylinder body 22 that revolves is made dovetail face (mechanics angle say can limit horizontally slips prevent to move up and down angle 55 degree), and this face cooperates with extensible guide precision after scraping.Guide rail has carried out laminating processing and has reduced friction simultaneously.Guide-track groove 24 and main revolving are provided with adjustment bolt 27 and liner plate 33 between the cylinder body, it is adjustable at any time by adjusting bolt 27 with guide clearance that the master is revolved cylinder body 22, very convenient, guaranteed that main spinning roller 28 works all the time in the best condition, improved the kinematic accuracy and the dynamic accuracy of main spinning roller greatly.
2, main spinning roller 28 is installed in bearing chamber 29 spinning roller axle 30 end positions outward, bearing chamber 29 physical dimensions are not subjected to the restriction of spinning roller endoporus.Main spinning roller 28 is contained in outside the bearing chamber 29, the specification and the spinning roller shaft diameter of bearing 311 and bearing 312 have been strengthened, the bearing 173 of original structure is replaced by present NU2320 profile shaft by 32312 types holds 313, improved spinning roller 28 stressing conditions, improved the bearing capacity and the spinning stationarity of spinning roller 28.Service life brought up to 26 months by original 2 months by bearing, reduced maintenance cost.Because spinning roller 28 is installed in axle head, spinning roller 28 dismountings are very convenient, can realize quick change, improve utilization rate of equipment and installations greatly, increased economic benefit.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
