Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further detailed explanation:
Embodiment 1: as shown in figures 1 and 3, a kind of improved semi-automatic internal grinder, comprises power set 4 and retaining wall 5, is connected with emery wheel 15 on described power set 4, described power set can come and go and move to material loading channel direction along guide rail.On described retaining wall 5 right side walls, be provided with material loading passage 2, as shown in Figure 6, described material loading passage comprises horizontal material loading passage 13 and vertical material loading passage 14.As shown in Figures 2 and 3, on described retaining wall 5, be provided with space 22 corresponding to vertical material loading channel position.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, on described power set 4, be provided with bridge 1, described bridge 1 is made up of two vertical bars 11,12 and a transverse bar 10, described vertical bar 1 is fixed on the power set 4 on material loading passage right side, vertical bar 2 12 is positioned at the left side of material loading passage, on described vertical bar 2 12, be provided with a horizontal stock 6, the certainly close material loading passage of the end face of described stock 6 one end is to deviating from the upwards lifting gradually of material loading passage one end.
As shown in Figure 4 and Figure 5, in order to make the height of stock 6 adjustable, side at vertical bar 2 12 is provided with slot 20, bottom is provided with tapped hole one, also being provided with the supporting screw rod in tapped hole two, one 9 at the bottom of described stock 6 correspondence position is fixed on stock in slot 20 through hole one and hole two.
As shown in Figure 1 and Figure 4, in order to adjust the lateral attitude of stock 6, on the transverse bar 10 of described bridge, be provided with Collapsible structure 19.
In practical operation, as shown in Figure 2, first first-class race ring in material loading passage, moves to emery wheel 15 in grinding position by power set, now adjusts the height of stock 6 by turn screw rod 9, makes it in suitable location.Described suitable location refers to that stock 6 is near second the tangent position of the interior dome of race ring 7 from bottom number in the end face of material loading passage one end and vertical material loading passage 14, as phase tangent line 21 positions in Fig. 2.
Certainly, stock 6 can select with second race ring in dome tangent, also can select with the 3rd, the 4th etc. race ring in dome tangent, but from realizing object of the present invention, selecting second is preferred plan, because select second can reduce to greatest extent race ring in the material loading passage pressure to bottom, the required thrust of jack-up race ring when reducing roller 8 as far as possible and rotating the material returned.
Also it should be noted that herein, the height of stock 6 does not really want to ask accurate and the interior dome of race ring is tangent, can there is suitable error, but can not make stock 6 near material loading passage one end, be positioned at the circle wall height and position of race ring, because can stop that like this stock 6 enters race ring inner circle jack-up race ring.
As shown in Figure 3, adjust after the height of stock 6, mobile power set 4, make emery wheel 15 leave grinding position, power set are to moving away from material loading channel direction, now stock 6 can move along with the movement of power set, behind the space 22 through on retaining wall 5, enter the inner circle of race ring, due to the end face of stock 6 near material loading passage one end to deviating from the upwards lifting gradually of material loading passage one end, so, stock 6 is after the interior dome of contact bearing circle, can be along with the mobile and race ring in jack-up material loading passage slowly, as shown in Figure 3, in the time that power set move to the highest distance position away from material loading passage, the body of rod height that stock 6 enters into race ring inner circle is the same with race ring inner circle diameter, if different, can be by adjusting the stretching structure of transverse bar, make it consistent.Certainly, also can make it consistent by the displacement farthest of motivation of adjustment device, also can in two ways and use.
Need explanation herein, in the time that power set move to the highest distance position away from material loading passage, the body of rod height that stock enters race ring inner circle can be less than interior circular diameter, but while can not power set also not moving to the highest distance position away from material loading passage, the body of rod height that stock enters race ring inner circle has just equaled interior circular diameter, because, if like this, in the time that power set continue to move, stock also can continue mobile, but the body of rod height that enters inner circle due to stock has equaled interior circular diameter, so the body of rod can drive race ring to move together, but being stopped by material loading passage, can not move toward this direction race ring, will produce like this interaction force, damage material loading passage or the body of rod.
Certainly, also have a kind of processing mode, control exactly the maximum height of the stock body of rod, make it be less than the interior circular diameter of race ring.
After all adjust the position of stock 6, just grinding work can be carried out.As shown in Figure 6, first material loading from horizontal material loading passage 13, until all completely expect in horizontal material loading passage 13 and vertical material loading passage 14, put race ring 2 17 well at the bearing position of roller 8, magnechuck on grinding machine holds race ring two, as the solid line part in Fig. 6, power set drive emery wheel 15 to move to grinding position, and start the inner circle of grinding bearing circle 2 17.
As shown in Figure 8, after to be ground getting well, power set drive emery wheel to moving away from material loading channel direction, now, stock 6 is also followed movement, the race ring 7 in the vertical material loading passage of jack-up, the roller rotation material returned, as shown in Figure 9, roller 8 rotates to material returned position, and the race ring 2 17 that grinding is good leaves bearing position, enters blanking channel 16, and roll out by the discharging opening 3 as in Fig. 1, then manually collect the race ring that this grinding is good.After roller 8 materials returned, reverse again, as shown in figure 10, in roller Umklapp process, the race ring of the bottommost in material loading passage falls into empty bearing position, roller is inverted to precalculated position, the magnechuck of grinding machine holds the race ring of bearing position, and then power set drive emery wheel to enter grinding position, and now stock 6 is along with the movement of power set, exit, put down the race ring in material loading passage.Emery wheel starts grinding bearing circle inner circle.So repeatedly.
In the prior art, stock is not set, like this will be as shown in Figure 7, when the roller rotation material returned, need all race rings in jack-up material loading passage, so just need very large thrust, under very large thrust, jack-up race ring smoothly, but, be inverted to behind precalculated position at roller, can produce very large power to support member 18, thereby affect the stability of support member, and then affect operating accuracy.And in jack-up process, the race ring 17 of bearing position can have a very large thrust left to the race ring in material loading passage, this thrust left can be applied on material loading passage, thereby affects the firm of material loading passage.And adopt after technical scheme of the present invention; will be as shown in Figure 8; there is the race ring except the race ring of bottommost in a stock jack-up material loading passage; thereby, in the time of the roller rotation material returned, just only need a race ring of jack-up bottommost; thereby only need less thrust; like this, the thrust left that the race ring in 2 17 pairs of material loading passages of the race ring of bearing position produces also can be very little, thereby can protect material loading passage.
