    • 专利摘要:
    The device is for transportation of annular work pieces which are to be externally or internally worked e.g. roller bearing rings. Each processing station has a loading arm which can pivot through 180 deg. between two work piece mounting positions. The loading arms are attached in series in planes parallel to the processing stations, at a separation roughly that of the width of the work piece. The work piece take ups are gathered together coaxially in front of a pre loading station when not in the working or operative position.

    The invention relates to a device for transporting ring blanks for selective internal or external processing.
    A device for feeding rings of ball bearings 5 on the grinding stan- ki comprising supply and discharge chutes mounted in the overload position of pusher for the articles and the pivot arm, which is aligned in the capture position overload inlet and outlet chutes and pusher [1] xlO
    The known device does not provide an abbreviated cycle of changing blanks when loading flocks, as well as loading machines with a sequential cycle of processing a single product.
    The invention aims ustrane- 15 of these disadvantages.
    For this, the proposed device is equipped with a pivot arm with a grip for the product, parallel to the main body and remote from it 20 at a distance corresponding to the width of the product, with the pivoting levers made two-gripping, and their grips are combined in the overload position with each other.

    FIG. 1 shows a front view of a device for the internal processing of parts; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a front view of a device for external machining of parts; in fig. 4 shows a section BB in FIG. 3
    FIG. 1 and 2 depict a transport device for a super-finishing machine for internally machined ring blanks, in particular rings of ball bearings. In the exemplary embodiment, the superfinishing machine is equipped with two processing stations 1 and 2 with the driving spindles 3, located in front of the loading arms 4 and 5, and with the U-shaped devices 6, 7 for clamping the workpiece and the tool holders 8, 9.
    Boot levers 4, 5 are located one after the other, i.e. in two planes. Each of them is provided at the ends with grippers in the form of clamping sleeves 10, 11 or 12, 13 for hydrostatic supports of the blanks. One of the clamping sleeves are located coaxially and in front of the driving spindles 3, i.e. in the working position, while the others are coaxial with each other in front of the loading station 14.

    is driven through the supporting spindles 15, 16 and the loading arms 4, 5. The driving spindles 3 are axially displaced by the width of the workpiece.
    Through the supply tray 17, the blanks 18 are placed in the loading station in front of the pusher 19. Tray 17 is adjusted so that the blanks 18 are located axially in front of the clamping sleeve 11.
    In the normal working process, the final hardened billet And is pre-machined, and the final billet is in the clamp bushing 13, while the pre-machining is performed in the clamp bushing 10 and the final machining is in the clamp bushing 12.
    Loading or the corresponding change of blanks is as follows.
    The pusher 19 moves the raw workpiece 18 to the clamping sleeve 11 of the loading arm 4 for pre-processing. At the same time already processed pre-workpiece 20 is moved from the clamping sleeve 11 of the loading lever 4 into the clamping sleeve 13 of the loading lever 5 for final processing and the finished blank 21 - from the loading lever 5 to the discharge tray 22.
    Upon completion of the processing of the workpiece in the processing stations 1, 2, the tool holders 8, 9 are moved away and the clamping devices 6, 7 are retracted, the workpieces are replaced. In this case, the support spindles 15, 16 with the loading arms 4, 5 rotate 180 °, and the blanks from the workstations are replaced with the blanks in the loading stations.
    The tool holders 8.9 and the clamping devices 6, 7 are reintroduced into the working position, the pusher 19 is moved back, the new raw billet rolls into the loading position, and the loading process starts again.
    Boot levers 4, 5 perform when changing blanks reciprocating swinging movement, so that the stops 23, 24 boot levers 4, 5 alternately lie on the stop screws 25, 26. Due to this, the final position of the boot levers 4, 5
    in each position can be adjusted independently of each other.
    If the workpieces in both stations must undergo preliminary and final processing at the same time, the pusher 19 operates twice in the processing stations, so that both the loading arm 4 and the loading arm 5 of the loading arm 5 fall into the clamping sleeve 11 of the loading arm 4 and finally the processed workpieces 20, 21 are ejected successively.
    FIG. 3 and 4 shows a device for blanks that are machined from the outside. The principle of operation will be the same as for the internal processing, only the blanks are not located in the loading arms 4, 5, but on the centering mandrels 27. The loading arms 4, 5 serve only for transporting the blanks that are centered in them. They are open on one side for the supply of tools. The centering mandrel 27 are displayed when changing blanks.
