Abstract

PURPOSE: A sliding muffler jig is provided to easily fix respective components of a muffler by adjusting a welding position corresponding to the structure of the muffler. CONSTITUTION: A sliding muffler comprises a plate(12), a horizontal transfer bar(14) slidably combined to the plate, a vertical transfer body(16) slidably inserted into the horizontal transfer bar, a fixed bar(20) having a thread combined to a thread recess(24) of the vertical transfer body, and a height adjusting bar(18) inserted into a thread recess(26) of the fixed bar. A fastening recess(28) is formed in the center of the fixed bar to apply a fastening force when being thread-connected with the thread recess of the vertical transfer body. A fastening screw(34) is inserted into a fastening screw inserting recess. The fastening screw inserting recess is formed on the outer face of the plate to fix the position of the horizontal transfer bar. A roller is attached to the inner face of the vertical transfer body to have the vertical transfer body slide easily. Welding is performed while the vertical transfer body is moved along the horizontal transfer bar and the combining position of components is adjusted accurately.

Description

Muffler jig of slide type}

The present invention relates to a slide type muffler jig, and more particularly, when the welding operation for the coupling of the muffler divided into several parts, by precisely adjusting the welding position between each component of the muffler, the welding operation easily It relates to a sliding muffler jig that can be carried out.

In general, the muffler is a place where the exhaust gas of the engine is purified and discharged to the outside, and various parts (engine exhaust pipe, purifier with a catalytic device, exhaust pipe, etc.) are installed according to the mounting portion of the bottom of the vehicle body. It is joined by welding into a curved shape.

The welding joining operation of the muffler made of several parts is carried out on a jig having a structure as shown in FIG. It is composed of a plurality of fixed "c" type support (36).

Therefore, after the parts are mounted on the support on the surface plate and fixed, the coupling parts are joined by welding, and each part of the muffler is inspected.

However, the conventional muffler as described above has to make a jig having a different structure for each type of vehicle as in the development of a new model, and there is a disadvantage in that waste of jig material and cost is severe, and also, as the jig is manufactured by welding, It has the disadvantage of reducing pollution and workability.

Accordingly, the present invention has been made to solve the above-described problems, and provides a slide-type muffler jig so that each part of the muffler can be easily fixed by adjusting the welding joint position of the muffler having a different structure for each vehicle type. Its purpose is to.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention has a surface plate 12 having a predetermined area, a horizontal transfer bar 14 which is slidably coupled to the upper and lower inner surfaces of the surface plate 12 to the left and right, and the horizontal transfer bar 14 up and down. A thread is formed at a lower end of the vertical conveying member 16 which is slidably inserted and has a screw groove 24 on the upper surface thereof, and a screw thread at the lower end thereof so as to be screwed into the screw groove 24 of the vertical conveying body 16, Height adjusting bar having a fixing bar 20 having a 26, and a seating portion 22 is inserted into the screw groove 26 of the fixing bar 20 so that each component of the muffler is mounted thereon. And 18).

In particular, the central portion of the fixing bar 20 is formed with a tightening groove 28 for providing a tightening force of the spanner when screwed into the screw groove 24 of the longitudinal transfer body 16.

In addition, on the side of the fixing bar 20, a tightening screw 34 is inserted to form a tightening screw insertion groove 32 penetrating to the screw groove 26 to tighten the height adjusting bar 18.

In addition, the outer surface of the surface plate 12 is formed with a tightening screw insertion groove 30 for fixing the position of the horizontal transfer bar (14).

In particular, the roller 38 is attached to the inner surface of the vertical transfer body 16 is inserted into the horizontal transfer bar 14 to facilitate the sliding.

Herein, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a perspective view showing the slide-type muffler jig 10 according to the present invention, and reference numeral 12 denotes a surface plate having a predetermined area in the transverse direction longer than the longitudinal direction.

Grooves are formed on the upper and lower inner surfaces of the surface plate 12, and a plurality of horizontal transfer bars 14 which are slidably moved in the left and right directions are coupled to the grooves.

That is, as shown in Figure 2, as the upper and lower inner surface of the surface plate 12 and the upper and lower ends of the horizontal transfer bar 14 is unevenly coupled, the horizontal transfer bar 14 is able to slide left and right, At this time, the upper and lower portions of the surface plate 12 is formed with a tightening screw insertion groove 30, by inserting a tightening screw 34 to the tightening the horizontal transfer bar (14) fixed by the slide transfer position, horizontally The transfer bar 14 is not fixed and is easily fixed in the adjusted position.

On the other hand, the vertical transfer body 16 as shown in Figure 2 attached to the horizontal transfer bar 14 to be slidably up and down is inserted, the roller 38 is provided on the inner surface of the vertical transfer body 16 It is attached, and the vertical conveyance body 16 is movable up and down by rolling the roller 38 with respect to the horizontal conveyance bar 14. As shown in FIG.

The upper surface of the vertical conveying member 16 is formed with a threaded groove 24 having a penetrating shape, the fixing bar 20 is screwed to the screw groove 24.

More specifically, the lower end of the fixing bar 20 is formed with a screw thread coupled to the screw groove 24 of the vertical carrier body 16, the upper screw thread 26 is formed, the central portion is Spanner tightening grooves 28 are formed.

At this time, the height adjustment bar 18 having a screw thread at the lower end is inserted into the upper screw groove 26 of the fixing bar 20, the concave seating portion 22 at the upper end of the height adjustment bar 18 Formed.

On the other hand, the tightening screw penetrated to the screw groove 26 on the side of the fixing bar 20 in order to securely fix the state that the height adjustment bar 18 is screwed to the screw groove 26 of the fixing bar 20 The insertion groove 32 is formed, and the tightening screw 34 tightens the height adjusting bar 18, whereby the position of the height adjusting bar 18 is firmly fixed.

Therefore, after placing the parts (exhaust pipe and septic tank) of the muffler on the seating portion 22 of the height adjustment bar 18, the horizontal transfer bar 14 is transferred along the upper and lower surfaces of the surface plate 12 and left and right. The position is determined, and the vertical conveying member 16 is moved up and down along the horizontal conveying bar 14 to determine the upper and lower positions, to exactly match the coupling position between the parts, and the height adjusting bar 18 is fixed to the bar ( 20) It is possible to easily perform welding work by adjusting the height by screw rotation.

Of course, the parts of the muffler of different structure can be precisely matched by the adjustment of the horizontal transfer bar, the vertical transfer body and the height adjusting bar, and also inspected for various cracks and abnormalities while the different structure mufflers are placed on the surface. Can be.

As seen from the above, according to the slide type muffler jig according to the present invention, even the muffler parts having different structures for each vehicle type can be welded freely by adjusting the coupling position, so that the muffler jig was produced at the time of developing a new model. There is an advantage to save material and cost by excluding.
