Abstract
The utility model discloses a kind of positioning devices of air duct punching, including support base, chain, the screw rod for being set to chain both ends and the adjusting nut being set on each screw rod, it is opened up on the support base there are two the jack being inserted into for the screw rod and the holding tank for accommodating the adjusting nut, a part of the adjusting nut is protruding from the holding tank.By adopting the above technical scheme, the positioning device of the air duct punching of the utility model, screw rod is able to drive in jack by rotating adjusting nut to move, the stainless steel air duct being placed on support base so as to pull chain to fasten, compared to the mode that traditional fixture grips, the power that chain acts on stainless steel air duct is more dispersed, and is distributed in the circumferential, so as to effectively avoid stainless steel air duct from deforming, and it is relatively firm.
Description
Technical field
The utility model relates to a kind of positioning devices of air duct punching, belong to air duct production process equipment technical field.
Background technique
Air duct be from one send air-flow to the channel gone at another place, such as heating air duct, cooling air channel or ventilation wind
Road.Carry out drilling operation in the manufacturing process in stainless steel air duct it is generally necessary on air duct, when drilling operation must be by air duct
Positioning is fixed, and traditional mode is by the way of fixture clamping, and this is easy to for being pinched in stainless steel air duct, and solid
It is also undesirable to determine effect.
Utility model content
Therefore, it the technical problem to be solved by the present invention is to provide a kind of fixed effect is preferable, while being also less prone to not
The positioning device for the air duct punching that rust steel air channel structure damages.
To achieve the goals above, the utility model a kind of air duct punching positioning device, including support base, chain,
The adjusting nut for being set to the screw rod at chain both ends and being set on each screw rod, open up on the support base there are two
Jack for screw rod insertion and holding tank for accommodating the adjusting nut, a part of the adjusting nut from
It is protruding in the holding tank.
The adjusting nut is installed in the holding tank by bearing.
Arc notch is provided on the support base for placing stainless steel air duct.
The chain includes the multiple chain links being hinged, and the side edge of each chain link is arc.
Two screw rods are arranged in parallel, so that the chain be enable to reach 180 ° around the radian in stainless steel air duct.
The positioning device of the air duct punching includes multiple chains.
By adopting the above technical scheme, the positioning device of the air duct punching of the utility model, can by rotating adjusting nut
Screw rod is driven to move in jack, the stainless steel air duct being placed on support base so as to pull chain to fasten, compared to biography
The mode that the fixture of system grips, the power that chain acts on stainless steel air duct is more dispersed, and distribution is in the circumferential, from
And stainless steel air duct can be effectively avoided to deform, and relatively firm.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
The utility model provides a kind of positioning device of air duct punching, including support base 1, chain 2, is set to 2 liang of chain
The screw rod 3 at end and the adjusting nut 4 being set on each screw rod 3, open up that there are two for described on the support base 1
The jack 12 and holding tank 11 for accommodating the adjusting nut 4 that screw rod 3 is inserted into, a part of the adjusting nut 4 from
It is protruding in the holding tank 11.
The adjusting nut 4 is installed in the holding tank 11 by bearing 5.The screw rod 3 is worn out of described jack 12
Out, and the traversing through end of the screw rod 3 is bolted with a fixture nut 6, can play fastening effect to screw rod.
Arc notch is provided on the support base 1 for placing stainless steel air duct.The chain 2 includes mutually cutting with scissors simultaneously
The multiple chain links 21 connect, the side edge of each chain link 21 are arc, so that the arcuate structure with the outer surface in air duct matches
It closes.
Two screw rods 3 are preferably arranged in parallel, so that the chain 2 be enable to reach around the radian in stainless steel air duct
To 180 °, to guarantee that chain 2 has longer contact length to stainless steel air duct.
The positioning device of the air duct punching includes multiple chains 2, and multiple chains 2 are used to fasten the difference in stainless steel air duct
Position, so that it be fixed in each different parts.
By adopting the above technical scheme, the positioning device of the air duct punching of the utility model, can by rotating adjusting nut 4
Screw rod 3 is driven to move in jack, the stainless steel air duct being placed on support base 1 so as to pull chain 2 to fasten, compared to
The mode that traditional fixture grips, the power that chain 2 acts on stainless steel air duct is more dispersed, and is distributed in circumferential direction
On, so as to effectively avoid stainless steel air duct from deforming, and it is relatively firm.
Obviously, above-described embodiment is only intended to clearly illustrate example, and does not limit the embodiments.For
For those of ordinary skill in the art, other various forms of variations or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments.And obvious variation extended from this or change
Among the dynamic protection scope created still in the utility model.
