Description

Technical Field

[0001] The utility model relates to the technical field of worm gear hoisting, in particular to a hoisting fixture for worm gear processing. Background Art

[0002] Worm gear hoisting refers to a series of hoisting technologies and special devices used in the worm gear production process to safely and efficiently transport and position the worm gear to the processing equipment (such as lathes, milling machines, grinders, etc.) for processing.

[0003] The existing worm gear lifting usually fixes the lifting clamp on the crane and then places the lifting clamp outside the worm gear. When the crane is lifting, the worm gear is clamped by closing the lifting clamp. However, when the lifting clamp clamps the outside of the worm gear, uneven force is easily applied, resulting in poor clamping stability and easy wear of the worm gear, which is inconvenient.

[0004] Therefore, a hoisting fixture for worm gear processing has been developed that can clamp the inside of the worm gear, ensure the stability of the worm gear during the hoisting process, and avoid wear of the worm gear. Utility Model Content

[0005] In order to overcome the shortcomings of existing worm gear hoisting, in which uneven force is easily applied when the hoisting clamp clamps the outside of the worm gear, resulting in poor clamping stability and easy wear of the worm gear, the utility model provides a hoisting clamp for worm gear processing that can clamp the inside of the worm gear, ensure the stability of the worm gear during the hoisting process, and avoid wear of the worm gear.

[0006] Technical solution: A hoisting fixture for worm gear processing includes a worm gear, an aluminum pad and a support frame, wherein the aluminum pad is placed on the upper side of the worm gear, and the upper side of the aluminum pad is connected to the support frame;

[0007] It also includes a hanging plate, a support plate and a connecting rod. The upper side of the support frame is provided with a hanging plate, the hanging plate is engaged with the support frame, and a plurality of supporting plates are connected to the lower side of the hanging plate, and the supporting plates are all rotatably connected with connecting rods;

[0008] It also includes a first rotating frame and a clamping frame. The lower part of the connecting rod is rotatably connected to the first rotating frame, the first rotating frame is rotatably connected to the supporting frame, and the lower part of the first rotating frame is rotatably connected to the clamping frame.

[0009] In addition, it is particularly preferred that a second rotating frame and a connecting piece are further included, the upper portion of the clamping frame is rotatably connected to the second rotating frame, the upper portion of the supporting frame is connected to a plurality of connecting pieces, and the second rotating frame is rotatably connected to adjacent connecting pieces.

[0010] In addition, it is particularly preferred that it also includes a connecting block, a connecting ring and a pull ring, the upper side of the hanging plate is connected to the connecting block, the connecting ring is rotatably connected to the connecting block, and a pull ring is sleeved between the connecting ring and the connecting block.

[0011] In addition, it is particularly preferred that it further includes an extrusion frame and a telescopic spring, the clamping frame is slidably connected to the extrusion frame, and the upper and lower parts of the extrusion frame are connected to the connected clamping frame with a telescopic spring.

[0012] The beneficial effect is: the utility model moves the hanging plate upward to detach from the supporting frame, so that the connecting rod rotates, and drives the first rotating frame to rotate, so that the clamping frame moves away from each other along the aluminum pad and engages with the worm gear to clamp the worm gear, thereby achieving the effect of being able to clamp inside the worm gear, ensuring the stability of the worm gear during the lifting process, and avoiding wear of the worm gear.
