Hand cannot coordinate different sizes, different shape bolts, and this method of hand Screw causes high effort in the stubborn bolt later stage, use
Inconvenience, loose unloading is difficult, and removal efficiency is low.
Utility model content
To solve existing poor universality, the technical problems such as removal efficiency is low, loose unloading is difficult, the utility model proposes one kind
Different shape, different size bolt screwing machine structures may be implemented, the similar product belonging to patent at this stage can be replaced, adopted
Technical solution is as follows：
A kind of Screw Tightening Machines structure of adjustable dimension, mainly by rotating body, rubber washer, outer sliding sleeve, slideable
Grip slide, grip gasket, straight pin and moment handle form, and the rotating body is by rotating body end cap and rotating body core
It is welded, rotating body helical guideway is equipped on the outside of rotating body, be taper surface on the inside of outer sliding sleeve.Wherein, in rotating body
Rotating body end cap both sides be provided with location hole, rotating body end cap is hinged by straight pin and moment handle；Rotation master
Body lower end is equipped with rubber washer, by being adhesively fixed on rotating body surface；Rotating body by rotating body helical guideway with
Outer sliding sleeve threaded engagement, and outer sliding sleeve can move along a straight line along rotating body core, outer sliding sleeve lower end are taper surface, and can be slided
Dynamic formula grip slide contacts；Main core bottom end is evenly arranged four identical guide rail grooves of size shape in rotating body,
And it is equipped at each guide rail groove with the fully mated slideable grip slide of groove, the effect of taper surface in outer sliding sleeve
Under, slideable grip slide can it is radial along the guide rail groove on main core, move synchronously, realize the adjusting of center bore；
Meanwhile contact surface is in arc-shaped in slideable grip slide, the grip gasket of same shape passes through gluing and slideable folder
Tight sliding block is fixed.
Utility model works principle is so that outer sliding sleeve is moved along a straight line along rotating body by rotating outer sliding sleeve, outer to make
Taper surface on sliding sleeve pushes four slideable grip slides to center radial direction, moves synchronously, and realizes center bore
The clamping for completing different type bolt is adjusted, turns the fastening that moment handle completes bolt later.
Before use, by rotating body core central aperture bolt to be twisted, outer sliding sleeve is rotated.Due to being taper inside outer sliding sleeve
Face, during outer sliding sleeve is along rotating body core downlink, taper surface pushes four equally distributed slideable grip slide edges
Orbital groove in rotating body is radial to center, moves synchronously, and center-hole diameter constantly reduces until realizing bolt
It fixes to clamp.After fishbolt, open moment handle to turn behind horizontal position moment handle complete bolt fastening or
Loose unloading.Similarly, bolt can be unclamped by reversely rotating locking sliding sleeve.
The utility model has the following advantages that：A kind of Screw Tightening Machines structure of adjustable dimension can realize different-diameter, no
Fixing to clamp for similar shape bolt, it is applied widely；Using lever principle, increases torque, realize the peace of bolt convenient and strength-savingly
Dress and loose unloading, simple in structure, fastening effect is good；Also, contact surface is equipped with grip gasket in slideable grip slide, convenient for patch
Different shape, various sizes of bolt are closed, clamping force is increased；Rotating body bottom end is equipped with rubber washer, can be to avoid work
The contact wear that the rotation of outer sliding sleeve generates rotating body end cap during work.
The feature and advantage of the utility model will be described in detail by example combination attached drawing.

Specific implementation mode
The utility model is described in further detail with example below in conjunction with the accompanying drawings：
As Figure 1-Figure 4, the Screw Tightening Machines structure of a kind of adjustable dimension of the utility model design, mainly by rotating
Main body 1, rubber washer 2, outer sliding sleeve 3, slideable grip slide 4, grip gasket 5, straight pin 6 and moment handle 7 form, institute
It states rotating body 1 to be welded by rotating body end cap 1.1 and rotating body core 1.3,1 outside of rotating body is equipped with rotating body
Helical guideway 1.2,3 inside of outer sliding sleeve is taper surface 3.1.Wherein, 1.1 both sides of rotating body end cap in rotating body 1 are provided with
Location hole, rotating body end cap 1.1 are hinged by straight pin 6 and moment handle 7；1 lower end of rotating body is equipped with rubber pad
Circle 2, by being adhesively fixed on 1 surface of rotating body；Rotating body 1 passes through rotating body helical guideway 1.2 and 3 spiral of outer sliding sleeve
Cooperation, and outer sliding sleeve 3 can move along a straight line along rotating body core 1.3, and 3 lower end of outer sliding sleeve is taper surface 3.1, and slidably
Formula grip slide 4 contacts；It is recessed to be evenly arranged four identical guide rails of size shape for 1.3 bottom end of main core in rotating body 1
Slot, and be equipped with the fully mated slideable grip slide 4 of groove at each guide rail groove, the taper surface 3.1 in outer sliding sleeve 3
Under the action of, slideable grip slide 4 can it is radial along the guide rail groove on main core 1.3, move synchronously, realize centre bore
The adjusting of diameter；Meanwhile contact surface is in arc-shaped in slideable grip slide 4, the grip gasket 5 of same shape by gluing with
Slideable grip slide 4 is fixed.
The operation principle of the utility model is so that outer sliding sleeve 3 is moved along a straight line along rotating body 1 by rotation outer sliding sleeve 3,
To make the taper surface 3.1 on outer sliding sleeve 3 push, four slideable grip slides 4 are radial to center, move synchronously, real
The adjusting of existing center bore, completes the clamping of different type bolt, turns the fastening that moment handle 7 completes bolt later.
Before use, by 1.3 central aperture of rotating body core bolt to be twisted, outer sliding sleeve 3 is rotated.Inside outer sliding sleeve 3
For taper surface 3.1, during outer sliding sleeve 3 is along rotating body 1.3 downlink of core, the promotion of taper surface 3.1 four is equally distributed can
Orbital groove of the slidingtype grip slide 4 in rotating body 1 is radial to center, moves synchronously, and center-hole diameter is continuous
Reduce until completing fixing to clamp for bolt.After fishbolt, moment handle 7 is opened to horizontal position, turns torque hand
Handle 7 completes fastening or the loose unloading of bolt.Similarly, bolt can be unclamped by reversely rotating locking sliding sleeve 3.
The utility model is illustrated by way of example above, but the utility model is not limited to above-mentioned specific implementation
Example, all ranges that the requires of the utility model protection is belonged to based on any changes or modifications that the utility model is done.
