Abstract
The invention belongs to technical field of tooling clamps, it is related to a kind of Simple detachable mechanism for being interference fitted part, including support base, the nut sleeve threaded connection screw rod of the support base centre of gyration, screw rod upper end is fixedly connected with the output end of handheld electrical machinery, circumferentially shape is uniformly hinged some transition plate devices on support base, and the be hinged drag hook in each transition plate device lower end, drag hook lower end is provided with hook.Product of the present invention uses high pulling torque handheld electrical machinery, can be used in the less working environment of radial dimension；By changing the position of bolt in the trench so as to change the available diameter of drag hook, working size scope is big；It is easy to the fast quick-detach of part, changes the outfit, reduces the working strength that changes the outfit.
Description
Technical field
The invention belongs to technical field of tooling clamps, is related to a kind of Simple detachable mechanism for being interference fitted part.
Background technology
Generally, after part is by interference fit, larger radial pressure can be produced on matching surface, thus
Frictional force is produced, to ensure the positive connection of part.Many frock clamps also use this economy of interference fit in design
Practical matching relationship, but when production improves and changes part, the dismounting of part is interference fitted all there is certain difficulty,
There has been no the solution of convenient and general and instrument for dismounting interference fit part at present.
The content of the invention
The present invention in view of the above-mentioned problems, providing a kind of Simple detachable mechanism for being interference fitted part, be easy to tear open by the disassembly mechanism
Unload interference fit part, at the same it is adjustable use size, reduce the usage amount of field tool, make to change the outfit more convenient.
According to technical scheme：A kind of Simple detachable mechanism for being interference fitted part, it is characterised in that：Including support
Seat, the nut sleeve threaded connection screw rod of the support base centre of gyration, screw rod upper end is fixedly connected with the output end of handheld electrical machinery, supported
Circumferentially shape is uniformly hinged some transition plate devices on seat, the be hinged drag hook in each transition plate device lower end, drag hook lower end
Provided with hook.
As a further improvement on the present invention, the transition plate device includes two pieces of rebounds arranged in parallel, and two
Individual rebound upper and lower ends are connected by a bolt respectively, wherein lower end of the bolt connection drag hook, upper terminal bolt and support base
It is connected.
As a further improvement on the present invention, the support base is provided with the regulating tank consistent with transition plate device quantity,
Each transition plate device is respectively arranged in corresponding regulating tank, and corresponding moving operation can be carried out in regulating tank.
As a further improvement on the present invention, the drag hook upper end is wide, lower end is narrow.
The technical effects of the invention are that：Product of the present invention uses high pulling torque handheld electrical machinery, can be less in radial dimension
Used in working environment；By changing the position of bolt in the trench so as to changing the available diameter of drag hook, working size scope
Greatly；It is easy to the fast quick-detach of part, changes the outfit, reduces the working strength that changes the outfit.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
In Fig. 1, including handheld electrical machinery 1, screw rod 2, support base 3, regulating tank 3-1, bolt 4, transition plate device 5, drag hook 6,
Hook 6-1, axle 7, axle sleeve 8, fixed bearing 9 etc..
As shown in figure 1, the present invention is a kind of Simple detachable mechanism for being interference fitted part, including support base 3, support base 3 return
Turn the nut sleeve threaded connection screw rod 2 at center, the upper end of screw rod 2 is fixedly connected with the output end of handheld electrical machinery 1, is on support base 3
Circle-shaped to be uniformly hinged some transition plate devices 5, the be hinged drag hook 6 in each lower end of transition plate device 5, the lower end of drag hook 6 is set
There is hook 6-1.
Transition plate device 5 includes two pieces of rebounds arranged in parallel, and two rebound upper and lower ends pass through one respectively
Root bolt 4 is connected, and wherein lower end of the bolt connection drag hook 6, upper terminal bolt are connected with support base 3.
Support base 3 is provided with the regulating tank 3-1 consistent with the quantity of transition plate device 5, and each transition plate device 5 is set respectively
In corresponding regulating tank 3-1, and corresponding moving operation can be carried out in regulating tank 3-1.
The upper end of drag hook 6 is wide, lower end is narrow.
The course of work of the present invention is as follows：During work, suitable position is selected as needed, by transition plate device 5 with drawing
Hook 6 is fastened with bolt 4, and screw rod 2 is withstood on to the shaft end for the interference fit part for needing to dismantle, the hook 6-1 of drag hook 6 is caught in into axle sleeve
Under 8, start handheld electrical machinery 1, drive screw 2 rotates, and support base 3 is moved upwards with respect to screw rod 2, drag hook 6 with support base 3 to
Upper motion, axle sleeve 8 is driven gradually to be separated upwards with axle 7.
