Description
Technical field
The utility model is widely used in mechanical, especially a kind of hoisting fixture of roof pressing type holding workpiece center of gravity.
Background technology
Current hoisting fixture is when lifting by crane workpiece, since the offset of workpiece center of gravity can cause workpiece turning or lateral pendulum
It is dynamic, it is unfavorable for loading and unloading.
Utility model content
The purpose of this utility model is to provide a kind of roof pressing types for making workpiece smoothly load and unload to keep hanging for workpiece center of gravity
Fill tooling.
In order to solve the above technical problems, the utility model roof pressing type keeps the hoisting fixture of workpiece center of gravity, including：Arm,
The arm is L-shaped；The bottom in described arm one end is arranged in block, the block；Arm is hooked, described one end for hooking arm is connected to
The outside of the arm other end is equipped with card slot in the hook arm.
Retaining mechanism is equipped on the hook arm, the position of the retaining mechanism is corresponding with the position of the card slot.
The retaining mechanism includes：Cavity, the cavity are arranged in the hook arm；Locking pin, the locking pin pass through
Fixation is set on the hook arm, and the tail portion of the locking pin is arranged in the cavity；Spring, the spring are arranged in institute
It states in cavity, the tail portion of the both ends of the spring respectively with the inner wall of the cavity and the locking pin offsets；Screw rod, the spiral shell
One end of bar is connect across the spring with the tail portion of the locking pin, and the other end of the screw rod stretches out the hook arm.
It is equipped with cushion cover in the outer sheath of the screw rod, the cushion cover is located at the outside for hooking arm.
It is equipped with hanging ring at the top of the arm.
The utility model roof pressing type keeps the hoisting fixture of workpiece center of gravity to stick into workpiece head in lifting with the card slot for hooking arm
Portion, lock-screw clamping workpiece；Workpiece turning and sideshake are limited with block, workpiece center of gravity can be kept, make the vertical court in shaft end
Under, workpiece can be made smoothly to load and unload.In addition, by pulling screw rod, the restoring force that the locking pin in cavity overcomes spring is made to receive backward
Contracting unclamps screw rod after workpiece is put into, by the restoring force of spring, locking pin is made to forward extend out to adapt to various sizes of workpiece
Workpiece is withstood, realizes positioning.Meanwhile cushion cover is set in the outside for hooking arm, the flexible range of locking pin can be defined.
Description of the drawings
Fig. 1 is the hoisting fixture structural schematic diagram one that the utility model roof pressing type keeps workpiece center of gravity；
Fig. 2 is the hoisting fixture structural schematic diagram two that the utility model roof pressing type keeps workpiece center of gravity；
Fig. 3 is the hoisting fixture locking mechanism structure schematic diagram that the utility model roof pressing type keeps workpiece center of gravity.

Specific implementation mode
The hoisting fixture of workpiece center of gravity is kept to be described in further detail the utility model roof pressing type below in conjunction with the accompanying drawings.
As shown in FIG. 1 to 3, the utility model roof pressing type keeps the hoisting fixture of workpiece center of gravity, including L-shaped arm 1,
Block 2 is welded on the bottom of 1 one end of arm, and the one end for hooking arm 3 is welded on the outside of 1 other end of arm, hanging ring 6 and 1 spiral shell of arm
Line connects.When lifting, the card slot 4 to hook arm 3 sticks into 7 head of workpiece, locking pin 9 (by the setting of fixing sleeve 12 on hooking arm 3)
Clamping workpiece 7；The overturning of workpiece 7 and sideshake are limited with block 2,7 center of gravity of workpiece can be kept, make shaft end vertically downward, can be made
Workpiece 7 smoothly loads and unloads.Specifically, 9 clamping workpiece 7 of locking pin is by pulling screw rod 5, the locking pin 9 in cavity 8 being made to overcome bullet
The restoring force of spring 10 adapts to various sizes of workpiece 7 to after-contraction, screw rod 5 is unclamped after workpiece 7 is put into, by spring 10
Restoring force makes locking pin 9 forward extend out and withstands workpiece 7, realizes positioning.Meanwhile cushion cover 11 is set in the outside for hooking arm 3, it can be right
The flexible range of locking pin 9 is defined.
The preferred embodiment created to the utility model above is illustrated, but the utility model is created not
It is limited to the embodiment, those skilled in the art can also make various under the premise of without prejudice to the invention spirit
Equivalent modification or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
