Abstract
The utility model provides a tool used for withdrawing an inner annular gear. The tool comprises an ejecting pushing mechanism and a clamping mechanism, wherein the clamping mechanism is arranged on one end of the ejecting pushing mechanism and is provided with at least one pair of crosspieces; the length of the crosspieces is smaller than the inner diameter of the inner annular gear; the ejecting pushing mechanism consists of a push rod and a connecting plate which is fixed on one end of the push rod; the crosspieces are positioned on the connecting plate; sliding grooves are arranged on the crosspieces; flanges are arranged on the opening parts of the sliding grooves; the connecting plate stretches into the sliding grooves and is limited by the flanges; and the crosspieces can move along the connecting plate through the sliding grooves. When the tool is used, an enclosure with the inner annular gear is placed on a workbench, the crosspieces are used for resisting the outer sides of the inner annular gear, the push rod is pressed by a pressing machine, the crosspieces are driven to squeeze the inner annular gear, and the inner annular gear can be withdrawn from the enclosure; and the tool has the advantages that the structure is simple, the use is convenient, the working efficiency is favorably improved, and material waste can be reduced.
Description
Technical field
The utility model relates to a kind of motor handling instrument, relates in particular to a kind of convenient instrument that takes out the motor ring gear.
Background technology
In some motors, be provided with ring gear in the casing, loosening in order to prevent ring gear, the external diameter of ring gear need to be a bit larger tham the internal diameter of casing, and ring gear is compressed into casing.This connected mode can guarantee that ring gear keeps stable in casing, but, if motor breaks down, ring gear is caused damage, can't work on, adopt general tool that ring gear is taken out from casing and have certain difficulty, easily to the casing injury, even ring gear is withdrawed from, casing can not reuse in the taking-up process, whole casing can only be scrapped, cause great waste.
Therefore, be necessary to design a kind of extracting tool, conveniently ring gear is taken out, promote removal efficiency from casing, reduce waste of material.
The utility model content
The purpose of this utility model provides a kind of ring gear frock of moving back, and with convenient ring gear is separated with motor casing.
The utility model is that the technical scheme that its technical problem of solution adopts is,
Move back the ring gear frock, include top-pushing mechanism and clamping mechanism, clamping mechanism is located at top-pushing mechanism one end, and clamping mechanism has at least one pair of strut rail, and the length of this strut rail is less than the internal diameter of ring gear;
Top-pushing mechanism is comprised of push rod and connecting plate, and connecting plate is fixed in push rod one end, and strut rail is positioned on the connecting plate;
The connecting plate centre is provided with screw, and the end of push rod has the screw thread that matches with this screw, and connecting plate and push rod join by screw and screw thread;
Strut rail is provided with chute, and the peristome of chute has flange, and connecting plate stretches in the chute, by flange connecting plate is carried out spacingly, and strut rail can be moved along connecting plate by this chute;
The connecting plate two ends are respectively equipped with lever, and stretch out to the connecting plate outside end of this lever, and the moving range of strut rail is limited;
Strut rail is provided with at least one pair of, is respectively in the connecting plate two ends;
Be provided with elastic mechanism between strut rail and the connecting plate, the strut rail after moving is set back;
The strut rail middle part has projection, and the length of this projection is less than the internal diameter of ring gear.
The utility model has the advantage of, during use, to place on the workbench with the casing of ring gear, and make strut rail prop up the ring gear outside, by press with push rod to pressing down, driving strut rail pushes ring gear, ring gear can be withdrawed from from casing, it is simple in structure, and is easy to use, be conducive to promote operating efficiency, reduce waste of material.
Description of drawings
Fig. 1 is the structural representation that moves back the ring gear frock that the utility model proposes.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As shown in Figure 1, the ring gear frock of moving back that the utility model proposes includes top-pushing mechanism and clamping mechanism, and clamping mechanism is located at top-pushing mechanism one end, and clamping mechanism has strut rail 1, and the length of strut rail 1 is less than the internal diameter of ring gear;
Top-pushing mechanism is comprised of push rod 2 and connecting plate 3, and connecting plate 3 is fixed in push rod 2 one ends, and strut rail 1 is positioned on the connecting plate 3;
Connecting plate 3 centres are provided with screw, and the end of push rod 2 has the screw thread that matches with this screw, and connecting plate 3 joins by screw and screw thread with push rod 2;
Strut rail 1 is provided with chute, and the peristome of chute has flange 4, and connecting plate 3 stretches in the chute, is undertaken spacingly by 4 pairs of connecting plates of flange 3, and strut rail 1 can be moved along connecting plate 3 by this chute;
Connecting plate 3 two ends are respectively equipped with lever 5, and stretch out to connecting plate 3 outsides the end of this lever 5, and the moving range of strut rail 1 is limited;
In the present embodiment, strut rail 1 is provided with a pair of, is respectively in connecting plate 3 two ends, and is balanced with the thrust that guarantees 1 pair of ring gear of strut rail;
Be provided with elastic mechanism between strut rail 1 and the connecting plate 3, the strut rail 1 after moving is set back;
Strut rail 1 middle part has projection 6, and the length of this projection 6 is less than the internal diameter of ring gear, and projection 6 can stretch in the ring gear, slides at ring gear to prevent strut rail 1.
During use, to place with the casing of ring gear on the workbench, make strut rail 1 prop up the ring gear outside, by press with push rod 2 to pressing down, drive 1 pair of ring gear of strut rail and push, ring gear can be withdrawed from from casing, it is simple in structure, easy to use, be conducive to promote operating efficiency, reduce waste of material.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
