Glass edge-grinding machine does not have chain drive carrier bar mechanism
The utility model relates to a kind of glass edge-grinding machine does not have chain drive carrier bar mechanism.
Glass itself is non-rigid object, and its variation track and clamping and location datum level have the relation of hinting obliquely at one by one in grinding process.Specific to glass linear edge polisher and straight line oblique line edge polisher, unstable or irregular as the orbit of carrier bar, so, the track of the glass machined surface that grinding goes out also changes thereupon, can't reach us and process desired shape and size requirement.
At present, the drive link of domestic glass edge-grinding machine does not hinder two kinds of versions: a kind of have a chain-type, promptly drives the vulcanized rubber plate with chain, friction-type motion on guide rail.This structure can only be processed some low-grade products, and because the working environment very abominable (mainly being that glass dust and water have corrosivity very much) of glass machinery, and within a short period of time, chain stretchings that be corroded lost carrier bar length precision; Another kind of structure is no chain, its structure as shown in Figure 3, primary structure is the casting forming aluminium sheet, in aluminium sheet processing parallel hole system, to wear the polished rod axle and connect, two ends are equipped with the zanjon bearing, make deep groove ball bearing rolling-operation on guide rail, there are the axis of guide and bearing location in the centre.This structure has two big fatal shortcomings: 1. two of the aluminium sheet of this structure very difficult processing of slotted holes, and the concentricity in hole and single file degree be cannot say for sure to demonstrate,prove the processing cost height very much; 2. this structure adopts aluminium alloy compression casting to be shaped, the processing back is riveted joint vulcanized rubber plate on the plate face, because the strain of aluminium alloy rigidity when clamping glass is very poor, so when clamping the glass running, change greatly, unstable, can not process high-quality glass product.
The purpose of this utility model is to provide a kind of can guarantee that the glass edge-grinding machine of machining accuracy does not have chain drive carrier bar mechanism.
In order to achieve the above object, glass edge-grinding machine of the present utility model does not have chain drive carrier bar mechanism, the hardened steel panel of comprise guide rail, fixedlying connected with guide rail, can be at the vulcanized rubber plate that moves on the guide rail direction, the middle axis of guide of fixedlying connected with the vulcanized rubber plate, the Button Block optical axis that is provided with on middle axis of guide vertical direction; The hardened steel panel is divided into three of upper, middle and lower; Be provided with fastening mechanism between hardened steel panel and the vulcanized rubber plate.
Fastening mechanism of the present utility model is divided into three parts: first is arranged between the top of the hardened steel panel of top or bottom and vulcanized rubber plate; Second portion is arranged between hardened steel panel, vulcanized rubber plate and the Button Block optical axis of top or bottom; Between hardened steel panel, the middle axis of guide and the vulcanized rubber plate in the middle of third part is arranged on.
Guarantee the precision location owing to adopted such scheme, the motion of vulcanized rubber plate of the present utility model all to press processing up and down, it can only be moved along guide rail by fore-and-aft direction, transmission is very steady, and the transmission accuracy height has guaranteed the product grinding quality.In addition, this structure is the processing of breakdown anchor clamps, and the recombinant assembling will process easily than the integral aluminum alloy carrier bar on technology, and whole rigidity is good.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is a topography of the present utility model;
Fig. 2 is a side view of the present utility model;
Fig. 3 is the side view of background technology;
Fig. 4 is the front view of the utility model first Button Block;
Fig. 5 is the front view of the utility model second Button Block;
Fig. 6 is the vertical view of the utility model second Button Block.
As shown in fig. 1, two blocks of vulcanized rubber plates 14 are clamped glass 15, move along the direction of guide rail 1, and the bistrique (not drawing among the figure) that the bottom is provided with carries out grinding to glass 15.Fixedly connected with three hardened steel panels, 2 usefulness screws in the guide rail side of " king " font, at the top of vulcanized rubber plate 14 with screw fixedly connected an end of first Button Block 6.The shape of first Button Block 6 and shown in Figure 4, its other end has an aperture, small clevis pin with head 3 is set in the hole, a deep groove ball bearing 5 also is housed on it, the two ends of small clevis pin with head 3 are provided with jump ring 4 location, make deep groove ball bearing 5 on first Button Block 6 be buckled in rolling-operation on the hardened steel panel 2 at top like this, limited the move left and right of vulcanized rubber plate 14.Between the 3rd hardened steel panel 2 in bottom and vulcanized rubber plate 14, also be provided with same member, make the operation of whole vulcanized rubber plate 14 synchronous up and down.
As depicted in figs. 1 and 2, the axis of guide 11 in the middle of being fixedly connected with at the middle part of vulcanized rubber plate 14, its other end with deep groove ball bearing 12 is housed, there are jump ring 13 location the termination.Deep groove ball bearing 12 is rolling-operation under the restriction of the hardened steel panel 2 of top and centre, has limited moving up and down of vulcanized rubber plate 14.
As shown in Figure 1 and Figure 2, be provided with second Button Block 9 below first Button Block 6, its shape is as shown in Fig. 5 and Fig. 6, and two ends are with holes, is between two holes in outstanding " ear ".Second Button Block 9 is screwed with vulcanized rubber plate 14 and is connected, and Button Block optical axis 7 is installed in two holes.Button Block optical axis 7 be arranged in parallel with vulcanized rubber plate 14, and promptly vertical with the direction of the middle axis of guide, its other end also is with second Button Block 9, and two ends all are equipped with deep groove ball bearing 10, and jump ring 8 location are arranged.Deep groove ball bearing 10 is pressed in rolling-operation on the inner face of hardened steel panel 2 of top and bottom.Second Button Block holds together whole machinery.
As shown in fig. 1, above-mentioned fastening mechanism is symmetrical arranged between two guide rails, guarantees the uniformity of entire machine operation.
