Abstract

The utility model relates to a welding clamp of air filter cleaner bracket assembly for heavy duty car. The utility model is provided with a rotating bracket assembly which can be rotary and a side nipping device which can move levelly on left side of the fixing device. The middle of the fixing device is provided with a first nipping clamp used for nipping the level part of the supporting plate on the closed plate, a second nipping clamp and a third nipping clamp of face to face used for nipping the arc face on two ends of the supporting plate, an adjustable positioning device used for adjusting the end face of the supporting plate, an arc shaped positioning supporting block used for supporting the bracket. The utility model can ensure the shared arc face contact line for the bracket and the supporting plate and the smoothing of side end as well as the level exact position of the closed plate, and the utility model is of a proper design and reliable positioning.

Description

A kind of air filter of automobile bracket assembly assembling-welding fixtures

(1) technical field under

The utility model relates to a kind of assembling-welding fixtures of automobile component, particularly a kind of assembling-welding fixtures of heavy-duty car air filter bracket assembly.

(2) background technology

At present large-scale production assembling-welding fixtures, cause can not guarantee the shared cambered surface contact wire of carriage and supporting plate and side is concordant and the tram of closure plate level, and carriage, backing plate relative size 15mm can not guarantee, thereby greatly influenced the assembling of empty filter drawstring, and the problem of scrapping that severe interference brought has taken place with other parts assembling.

(3) summary of the invention

The utility model is at the deficiencies in the prior art, provide a kind of reasonable in design, locate reliable assembling-welding fixtures, to guarantee the concordant tram with the closure plate level of carriage with shared cambered surface contact wire of supporting plate and side.

The utility model is realized by following measure:

The utility model discloses a kind of air filter of automobile bracket assembly assembling-welding fixtures, include fixture, adorn welder, have the location tray of fastening screw; The side direction binding clasp that in the left side of fixture rotatable rotary bracket assembly is installed, can move horizontally; First clamp, the second relative clamp and the 3rd clamp that are used to clamp the two ends of bearing plate cambered surface, the adjustable locator that is used to regulate the supporting plate end face that is used to clamp plane on supporting plate horizontal position and the closure plate, the arc location tray that is used for Support bracket are installed at the middle part of fixture.

Assembling-welding fixtures of the present utility model, its using method is:

1. utilize the rotary bracket assembly to guarantee the closure plate positive stop.Make plane maintenance level and assurance bulk 6mm (as the size in Fig. 2 left view) on the closure plate, the end face location is carried out by the keeper on the rotary bracket assembly in the left side, clamps by side direction binding clasp side direction.

2. utilize two to position and place roughly behind the plane on taking by closure plate on supporting plate left end plane to the supporting plate arc-shaped side edges at the adjustable locator on the same straight line.

3. make supporting plate arcwall face and carriage arcwall face correct corresponding and under the effect of second clamp and the 3rd clamp power, rely on and guarantee to be adjacent to the accuracy that the while also recovered the arcwall face shape of coincideing and make each part reach relative correct position under the effect of the first clamp power by arc location tray in the space.

The beneficial effects of the utility model are, and are reasonable in design, the location is reliable, guaranteed the concordant tram with the closure plate level with shared cambered surface contact wire of supporting plate and side of carriage, reached desirable assembling quality requirement.

(4) description of drawings

Fig. 1 is a main TV structure schematic diagram of the present utility model

Fig. 2 is the left view of Fig. 1

Fig. 3 is the vertical view of Fig. 1

Among the figure, 1 rotary bracket assembly, 2 first clamps, 3 adjustable locators, 4 second clamps, 5 the 3rd clamps, 6 fastening screws, 7 side direction binding clasps, 8 arcs location tray, 9 location trays, 10 rhombus locking nuts, plane on 11 closure plate

(5) specific embodiment

As Fig. 1-3 shelves, be the structural representation of present embodiment.This assembling-welding fixtures includes fixture, adorns welder, the have fastening screw location tray (9) of (6); The side direction binding clasp (7) that in the left side of fixture rotatable rotary bracket assembly (1) is installed, can move horizontally; First clamp (2), second clamp (4) and the 3rd clamp (5) that are symmetry that are used to clamp the two ends of bearing plate cambered surface, the adjustable locator (3) that is used to regulate the supporting plate end face that is used to clamp plane on supporting plate horizontal position and the closure plate, the arc location tray (8) that is used for Support bracket are installed at the middle part of fixture.

Its using method is:

As shown in drawings, under the state that satisfies the correct location of carriage, utilize rotary bracket assembly (1) to locate and lock by rhombus locking nut (10), place closure plate, guarantee plane (11) level and bulk 6mm on the closure plate, the termination positions by the location tray (9) in the rotary bracket assembly, and its medial surface and carriage lateral surface are fitted, and relies on side direction binding clasp (7) to carry out side direction and clamps.

Place supporting plate, its side locating surface is by two adjustable locators (3) location, and take by placing roughly behind the plane on the closure plate on the left end plane

Utilize the power of first clamp (2) to be fitted in plane (11), rely on the locating surface of adjustable locator (3) to make the supporting plate cambered surface slide into correct locus naturally simultaneously.

Under the effect of second clamp (4) and the 3rd clamp (5) power, rely on arc location tray (8) to rely on to make two ends of bearing plate cambered surface and carriage two ends cambered surface to form the correct applying position that compresses.

Use location tray (9) and fastening screw (6) to guarantee carriage, backing plate relative size 15mm.

Claims

1. air filter of automobile bracket assembly assembling-welding fixtures, include fixture, adorn welder, the have fastening screw location tray (9) of (6), it is characterized in that: the side direction binding clasp (7) that in the left side of fixture rotatable rotary bracket assembly (1) is installed, can move horizontally; First clamp (2), relative second clamp (4) and the 3rd clamp (5) that are used to clamp the two ends of bearing plate cambered surface, the adjustable locator (3) that is used to regulate the supporting plate end face that is used to clamp plane on supporting plate horizontal position and the closure plate, the arc location tray (8) that is used for Support bracket are installed at the middle part of fixture.
