Description

Oiliness bearing endoporus automatic reforming device
Technical field
The utility model relates to a kind of oiliness bearing endoporus automatic reforming device.
Background technology
Powder metallurgy oil-impregnated bearing seamed edge in compacting process is jagged, and the endoporus of oiliness bearing is pilot hole, and burr or wedge angle impact assembling, the endoporus of oiliness bearing needs by shaping (face is beaten) operation to remove its sharp-pointed burr.As shown in Figure 1, product promotes from track to side ordinary powder metallurgical brearing bore shaping track by manipulator, carries out endoporus shaping to during die cavity position.The movement of product in track of the product large for depth-width ratio and side not rounded has some setbacks.The product that depth-width ratio is large has by the hidden danger of pushing over when track foremost; And be that the columniform product orientation of non-fully is forbidden to side, cause damage of product in endoporus shaping.Such as, for not rounded product, shown in Fig. 2, irregular position will change the center of non-fully cylindrical product, and center change, by causing the product orientation of not rounded to be forbidden, causes face to hit damage of product.
Utility model content
The purpose of this utility model is to provide one and makes product pinpoint oiliness bearing endoporus automatic reforming device.
In order to reach above-mentioned technical purpose, the technical solution of the utility model is:
A kind of oiliness bearing endoporus automatic reforming device, comprise feed rail, described feed rail is provided with die cavity position, oiliness bearing carries out endoporus shaping when feed rail enters into die cavity position, described die cavity position is provided with jaw, described jaw is made up of a pair elastic claw, described elastic claw is distributed in the both sides of feed rail, be arranged on the both sides of feed rail by central shaft in the middle part of described elastic claw, the retaining part of described elastic claw head is arc-shaped, the arc diameter of described retaining part is identical with the external diameter of oiliness bearing, the retaining part of described elastic claw head is for clamping oiliness bearing, the afterbody of described elastic claw is provided with back-moving spring, when the head of elastic claw is without gripping object, back-moving spring makes elastic claw be in and treats duty, and time between the retaining part that oiliness bearing enters two elastic claw heads, back-moving spring makes elastic claw clamp oiliness bearing.
Described elastic claw is provided with the adjustment screw of adjustment elastic claw motion amplitude.
When the head of elastic claw is without gripping object, back-moving spring makes elastic claw be in and treats duty; When oiliness bearing product introduction jaw, back down elastic claw, after entering the jaw retaining part of two elastic claw heads (namely enter between) completely, jaw is due to the elastic reset effect of back-moving spring, ensure that the arc surface of product and elastic claw head retaining part is fitted, product is in mold center, realizes registration, can not cause damaging in endoporus reforming process containing bearing products.Reforming process operates steadily, and realizes automation.
Accompanying drawing explanation
Fig. 1 is that in prior art, apparatus structure schematic diagram is played in face.
Fig. 2 is not rounded oiliness bearing product schematic diagram.
Fig. 3 is the utility model device schematic diagram.
Fig. 4 is that oiliness bearing product starts to enter station and backs down elastic claw schematic diagram.
Fig. 5 is that oiliness bearing product enters station completely and backs down elastic claw schematic diagram.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 3, a kind of oiliness bearing endoporus automatic reforming device, comprises feed rail, described feed rail is provided with die cavity position, and oiliness bearing 1 carries out endoporus shaping when feed rail enters into die cavity position.
Described die cavity position is provided with jaw, described jaw is made up of a pair elastic claw 2, described elastic claw 2 is distributed in the both sides of feed rail, be arranged on the both sides of feed rail by central shaft in the middle part of described elastic claw 2, the retaining part of described elastic claw 2 head is arc-shaped, the arc diameter of described retaining part is identical with the external diameter of oiliness bearing 1, and the retaining part of described elastic claw 2 head is for clamping oiliness bearing 1.
Back-moving spring 5 is provided with at the afterbody of elastic claw 2, when the head of elastic claw 2 is without gripping object, back-moving spring 5 makes elastic claw 2 be in and treats duty, and time between the retaining part that oiliness bearing 1 enters two elastic claw 2 heads, back-moving spring 5 makes elastic claw 2 clamp oiliness bearing 1.
During work, as shown in Figure 4,5, oiliness bearing 1 enters jaw, back down elastic claw 2, after entering jaw completely the retaining part of two elastic claw 2 heads (namely enter completely between), by existence two kinds may: one is the open slot region that the retaining part of elastic claw 2 head avoids oiliness bearing 1, and the center of oiliness bearing 1 then can be determined.Two is open slot regions that the retaining part of elastic claw 2 head does not avoid oiliness bearing 1, such arc surface of elastic claw head retaining part and the open slot of oil bearing 1 " meet ", because the arc diameter of retaining part is identical with the external diameter of oiliness bearing 1, oiliness bearing 1 is fitted with the arc surface of elastic claw 2 head retaining part, can not change the center of oiliness bearing 1.
Elastic claw 2 is also provided with adjustment screw 3, and the position of oiliness bearing 1 for adjusting the motion amplitude of elastic claw 2, thus can accurately be located by adjustment screw 3 further.The setting of adjustment screw 3 ensure that the uniqueness of each centralized positioning of oiliness bearing 1.
In order to coordinate the endoporus shaping of the oiliness bearing 1 of different size, elastic claw 2 head retaining part can be changed, for mating the oiliness bearing 1 of different size.
Above-described embodiment limits the utility model never in any form, and the technical scheme that the mode that every employing is equal to replacement or equivalent transformation obtains all drops in protection domain of the present utility model.
