Description
Technical field
The utility model relates to a kind of frame of tire sander, belongs to the mill tire equipment technical field in the tyre rebuilding.
Background technology
Junked tire is overhauled and utilized is the main path of tire resource circulation utilization, also is the major measure of junked tire decrement.The tire sander is to be used to polish the surperficial equipment of old tire.The frame of tire sander is the basis that the various members of tire sander are installed, and the precision that the position concerns between the various member installation surface on the tire polishing frame is to influence tire sander polishing accuracy factors.
The frame of tire sander generally partly is made up of crossbeam, left column, right column and base plate etc. in the prior art.Like Fig. 1, shown in Figure 2, the frame 1 of sander comprises left and right two columns, base plate and crossbeams.Jack up unit 2 is installed, clamping device 3, sidewall sanding apparatus 4, side sanding apparatus 5, drive unit 6, carriage 7, sanding apparatus 8, measuring thickness device 9 on the frame.Sanding apparatus 8 is installed on the carriage 7, and carriage 7 is installed on the base plate, can parallel direction along the column medial surface and slidably reciprocate.On frame two heel posts main shaft is housed all, front-end of spindle is equipped with chuck, and chuck blocks tire and polishes.Sander will be realized the high accuracy operation, require the coaxial precision of two main shafts to want high, otherwise tire quality can be influenced.See that from position relation if the medial surface of two columns is parallel, two vertical medial surfaces of main shaft guarantee coaxially just to become easy.The cutter head of cylindric high speed rotation on the sanding apparatus is done the aggregate motion of all around, rotation, polish surface of tyre to meet the curved profile of radian requirement once.Cutter head requires the cutter head direction that seesaws to want vertical major at the volley, and the side-to-side movement direction is wanted parallel main axis.It is thus clear that each member of tire sander is very high to parallel, the vertical positional relationship and the isoparametric required precision of flatness of the mounting plane of framework.
The processing mode of tire sander frame is divided into three kinds substantially in the prior art.First kind of traditional method, as shown in Figure 3, at first process the medial surface of left column 10 and right column 12 separately with milling machine.In order to make the vertical medial surface of main shaft, need measure two medial surfaces of calibration with dial gauge, make the two keeping parallelism after; Spot-welded together column and crossbeam 11, excessive for preventing welding deformation, before degree of depth welding; Use frock, anchor clamps, interim support etc., the framework of spot welding is reinforced, then according to a definite sequence; Welding symmetrically, discontinuous at times welding.Welding finishes it is cooled off fully.After cooling is accomplished, the framework integral solder to base plate 16.Base plate 16 is that welding is before through milling machine processing, as the mounting plane that the cutter head knife rest is installed.The medial surface of perfect condition lower pillar stand is a vertical base plate in theory.Welding deformation has caused two medial surfaces not parallel, the also not parallel base plate of the main shaft of general frame.
