Abstract
The utility model relates to novel tentering fixtures, rack body (1), clamp arm (4) and idler wheel (9) including whole S-shaped setting, the top of the rack body (1) is provided with bearing spider (7), lower part is removably equipped with gullet plate (3) by bolt (2), and the idler wheel (9) is mounted on bearing spider (7) by what fixing axle (8) rotated.The utility model has the advantages that: 1, sawtooth plate surface be zigzag design, can increase the anti-anti-avulsion folder of frictional force when clamping workpiece.2, gullet plate is detachable installation, can arbitrarily be replaced after abrasion, and use cost is reduced.3, clamp arm head end with clamp arm openings of sizes change with cooperate gullet plate cooperation can house ornamentation different-thickness workpiece, it is applied widely.
Description
Technical field
The utility model relates to a kind of fixture more particularly to a kind of novel tentering fixtures.
Background technique
The working principle of common tentering fixture is that tentering fixture is driven by executing agency, and tentering fixture clamps soil using clamping opening
Work grid is acted on by the gradually wide mobile drawing completed to TGXG of tentering fixture.Tentering fixture is usually flat by two
Capable plane steel plate composition, the distance by controlling two plane steel plates clamp TGXG.Grid material be generally polypropylene,
In the form of the high molecular polymers such as polyvinyl chloride, surface is smooth, and TGXG is thick in node, rib is thin, outer surface is not yet
It is smooth.So by two plane steel plates clamp TGXG there are several respects the drawbacks of: 1) traditional clamp structure does not adapt to
The TGXG of different-thickness, there are insufficient clamping force, the shortcomings that high failure rate；2) since fixture upper jaw face is plane,
Rotation is easy to damage TGXG during clamping, and the later period for influencing TGXG uses；3) common tentering fixture
Clamping opening structure be parallel clamping opening, the thickness range of clamping is small, and production efficiency is low, additionally, due to TGXG uneven thickness, holds
It is insecure easily to there is clamping, causes de- folder.
Summary of the invention
To overcome the shortcomings of existing technologies, the utility model provides a kind of novel tentering fixture, the technology of the utility model
Scheme is:
Novel tentering fixture, rack body (1), clamp arm (4) and idler wheel (9) including whole S-shaped setting, bracket master
The top of body (1) is provided with bearing spider (7), and lower part is removably equipped with gullet plate (3), the rolling by bolt (2)
Wheel (9) is mounted on bearing spider (7) by what fixing axle (8) rotated, is provided in the middle part of the rack body (1) mutually flat
Capable both side plate (6), what is rotated between both side plate is equipped with pin shaft (5), and the clamp arm (4) is fixedly installed on pin shaft (5),
The head end of the clamp arm (4) is in involute surface structure setting, is formed close to the gullet plate (3), and between gullet plate (3)
The space of clamping workpiece；The tail end of the clamp arm (4) forms handle.
A rectangular opening is provided on the rack body, the idler wheel rotates in the rectangular opening.
It is provided with mounting hole on the rack body, the mounting hole (10) is close to the rectangular opening.
The joint face of adjacent two plane of the head end of the clamp arm is smooth arc transiting surface.
The utility model has the advantages that:
1, sawtooth plate surface is zigzag design, can increase the anti-anti-avulsion folder of frictional force when clamping workpiece, and gullet plate
It detachably to install, can arbitrarily be replaced after abrasion, reduce use cost.
2, the head end of clamp arm changes the workpiece that different-thickness can be clamped with cooperation gullet plate cooperation with clamp arm openings of sizes, fits
It is wide with range.
3, the head end of clamp arm is in involute surface structure setting, and the more presss from both sides the more tight can to prevent from loosening, and use is safer.
Detailed description of the invention
Fig. 1 is the agent structure schematic diagram of the utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the top view of Fig. 1.
Fig. 4 is the use state of the utility model with reference to figure.
Specific embodiment
Further describe the utility model combined with specific embodiments below, the advantages of the utility model and feature will be with
Description and it is apparent.But examples are merely exemplary for these, does not constitute any restrictions to the scope of the utility model.
It will be understood by those skilled in the art that can be to the utility model skill under the spirit and scope without departing from the utility model
The details and form of art scheme are modified or are replaced, but these modifications and replacement each fall within the protection scope of the utility model
It is interior.
Referring to Fig. 1 to Fig. 4, the utility model relates to a kind of novel tentering fixture, the bracket master including whole S-shaped setting
Body 1, clamp arm 4 and idler wheel 9, the top of the rack body 1 are provided with bearing spider 7, and lower part is removably equipped with by bolt 2
Gullet plate 3, for placing workpiece, the idler wheel 9 is mounted on bearing spider 7 by what fixing axle 8 rotated, in bracket master
The middle part of body 1 is provided with the both side plate 6 being parallel to each other, and what is rotated between both side plate is equipped with pin shaft 5, what the clamp arm 4 was fixed
Be mounted on pin shaft 5, the head end of the clamp arm 4 is in involute surface structure setting, close to the gullet plate 3, and with gullet plate 3
Between formed clamping workpiece space；The tail end of the clamp arm 4 forms handle.
A rectangular opening is provided on the rack body 1, the idler wheel 9 rotates in the rectangular opening.
Mounting hole 10 is provided on the rack body, the mounting hole 10 is close to the rectangular opening, the peace
It fills hole and is used for being connected and fixed between rack body and other component.
The joint face of adjacent two plane of the head end of the clamp arm is smooth arc transiting surface.
The working principle of the utility model is: lift the handle of clamp arm, the gap between clamp arm head end and gullet plate at this time
It is gradually opened to maximum, after TGXG enters clamping space, depresses the handle of clamp arm, clamp arm head end gradually pushes, soil
Work grid is clamped between the head end of clamp arm and gullet plate, and since its involute structure is arranged, the more can press from both sides the more tight, effective anti-
Only TGXG loosens.
