Abstract
The utility model discloses a pre-catalytic-converter assembly air inlet end flange bolt welding protective device which comprises a base plate (1), wherein sleeves (2) are arranged on the base plate (1), the sleeves (2) are adaptive to bolts (5) of a pre-catalytic-converter assembly air inlet end flange, support rods (3) are arranged on the base plate (1), and magnets (4) are arranged on ends of the support rods (3). When the device is used, the sleeves are completely covered on the bolts (5), and in welding, generated sparkles are spattered on the sleeves (2) but not spattered on the bolts (5), and good protection can be achieved for the bolts (5) of the pre-catalytic-converter assembly air inlet end flange.
Description
Technical field
The utility model belongs to pre-catalytic converter assembly apparatus field, relates in particular to a kind of pre-catalytic converter assembly inlet end flange bolt welding protection device.
Background technology
Pre-catalytic converter assembly inlet end flange (as shown in Figure 2) is connected with the enmgine exhaust flange, pre-catalytic converter assembly is when welding, splashing that welding produces produces damage to bolt, can't be connected with the enmgine exhaust flange after the bolt failure, causes the generation of useless part.
The utility model content
Can be to the hurtful defective of pre-catalytic converter assembly inlet end flange bolt for welding process, technical problem to be solved in the utility model provides a kind of pre-catalytic converter assembly inlet end flange bolt welding protection device that can protect bolt in welding process.
In order to solve the problems of the technologies described above; the technical scheme that the utility model adopts is: a kind of pre-catalytic converter assembly inlet end flange bolt welding protection device; comprise base plate; described base plate is provided with sleeve; described sleeve is suitable with the bolt of pre-catalytic converter assembly inlet end flange; described base plate is provided with support bar, and described support bar end is provided with magnet.
Described sleeve and base plate welding.
Described sleeve has two.
Described support bar has two, between two described sleeves.
The utility model has the advantage of; can well protect the bolt of pre-catalytic converter assembly inlet end flange; magnet can firmly be positioned at protective device on the pre-catalytic converter assembly inlet end flange; sleeve covers bolt fully; during welding, the spark of generation spatters on sleeve, and can not spatter on bolt; simple in structure, easy to operate.
Description of drawings
Fig. 1 is the structural representation of a kind of pre-catalytic converter assembly inlet end flange bolt welding protection device of the utility model;
Fig. 2 is the structural representation of pre-catalytic converter assembly;
Mark among the above-mentioned figure is: 1, base plate, 2, sleeve, 3, support bar, 4, magnet, 5, bolt.
The specific embodiment
Fig. 1 is the structural representation of a kind of pre-catalytic converter assembly inlet end flange bolt welding protection device of the utility model; comprise base plate 1; described base plate 1 is provided with sleeve 2; described sleeve 2 is suitable with the bolt 5 of pre-catalytic converter assembly inlet end flange; described base plate 1 is provided with support bar 3, and described support bar 3 ends are provided with magnet 4.Described sleeve 2 and base plate 1 welding.Described sleeve 2 has two.Described support bar 3 has two, between two described sleeves 2.
During use, this device is sleeved on the pre-catalytic converter assembly, sleeve 2 is enclosed within on two bolts 5, support bar 3 plays a supportive role, magnet 4 on the support bar 3 firmly is adsorbed on the pre-catalytic converter assembly inlet end flange, makes that this device can not come off easily in the operating process, begins afterwards weld job.
After adopting such structure; can well protect the bolt 5 of pre-catalytic converter assembly inlet end flange; magnet 4 can firmly be adsorbed in protective device on the pre-catalytic converter assembly inlet end flange; sleeve 2 covers bolt 5 fully; during welding, the spark of generation spatters on sleeve 2, and can not spatter on bolt 5; simple in structure, easy to operate.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
