Abstract

The utility model belongs to the technical field of machining equipment, and particularly relates to a trombone horn mouth auxiliary welding tool which comprises a base. A vertical shaft sleeve and a motor are arranged on the base. A rotating shaft is inserted in the shaft sleeve, and the top of the rotating shaft is provided with a rotary disc. The rotating shaft is fixedly connected with a driven gear, and a motor shaft of the motor is provided with a driving gear meshed with the driven gear. The middle of the rotary disc is provided with a horn mouth mould used for containing the open portion of a horn mouth. The trombone horn mouth auxiliary welding tool further comprises a pressing device used for fixing the tail tube portion of the horn mouth and enabling the tail tube portion to be in butt joint with the open portion. The trombone horn mouth auxiliary welding tool is simple in structure, and good in fixing and locating effect due to the fact that the open portion of the horn mouth is fixed by the horn mouth mould in a supporting mode and the tail tube portion of the horn mouth is fixed by the pressing device in a pressing mode; the motor drives the rotary disc to rotate, and welding is carried out on the horn mouth in the overall rotating process.

Description

Trombone horn mouth auxiliary welding tool

Technical field

The utility model belongs to machining equipment technical field, relates in particular to a kind of trombone horn mouth auxiliary welding tool.

Background technology

As shown in Figure 1, the horn mouth of trombone generally comprises two parts, i.e. uncovered part 2 and tail pipe part 1, and both obtain by parts processing, carry out afterwards welding assembly.Due to shape irregular, the thinner distortion of easily colliding with of sidewall of uncovered part 2 and tail pipe part 1, therefore have difficulties when welding processing.

Utility model content

The utility model for solve the technical problem existing in known technology provide a kind of simple in structure, fix and position effective trombone horn mouth auxiliary welding tool.

The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: trombone horn mouth auxiliary welding tool comprises base, on described base, be provided with vertical axle sleeve and motor, in described axle sleeve, be inserted with the rotating shaft that top is provided with rotating disk, in described rotating shaft, be connected with driven gear, on the motor shaft of described motor, be provided with the driving gear meshing with described driven gear, at the middle part of described rotating disk, be provided with for placing the horn mouth mould of bell-mouthed uncovered part; Also comprise bell-mouthed tail pipe is partly fixed and makes it the hold down gag that docks with uncovered part.

Advantage of the present utility model and good effect are: welding tooling of the present utility model is simple in structure, bell-mouthed uncovered part and tail pipe part are fixed and are fixed by horn mouth mould support respectively, fix and position effective, motor drives turntable rotation, and horn mouth welds integrally rotated time.

Preferably: described hold down gag comprises the longeron that is fixed in described base and the crossbeam that is fixed in described longeron top, on described crossbeam, offer the vertical through hole over against described center of turntable, in described through hole, be inserted with threaded rod, the top of described threaded rod is provided with nut, bottom is provided with the briquetting with vertical jack, on described threaded rod, be also arranged with spring, described spring is between described briquetting and crossbeam.

Accompanying drawing explanation

Fig. 1 is the bell-mouthed structural representation of trombone;

Fig. 2 is structural representation of the present utility model and partial sectional view.

In figure: 1, tail pipe part; 2, uncovered part; 3, threaded rod; 4, spring; 5, briquetting; 6, crossbeam; 7, longeron; 8, base; 9, rotating disk; 10, horn mouth mould; 11, rotating shaft; 12, driven gear; 13, axle sleeve; 14, driving gear; 15, motor.

The specific embodiment

For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples and be described in detail as follows:

Refer to Fig. 2, the utility model comprises base 8, on base 8, be provided with vertical axle sleeve 13 and motor 15, in axle sleeve 13, be inserted with the rotating shaft 11 that top is provided with rotating disk 9, in rotating shaft 11, be connected with driven gear 12, on the motor shaft of motor 15, be provided with the driving gear 14 with driven gear 12 engagements.At the middle part of rotating disk 9, be provided with for placing the horn mouth mould 10 of bell-mouthed uncovered part 2, also comprise bell-mouthed tail pipe part 1 is fixed and makes it the hold down gag that docks with uncovered part 2.

In this example, hold down gag comprises the longeron 7 that is fixed in base 8 and the crossbeam 6 that is fixed in longeron 7 tops, offers over against the vertical through hole at rotating disk 9 centers on crossbeam 6.In through hole, be inserted with threaded rod 3, its top is provided with nut, bottom is provided with the briquetting 5 with vertical jack, is also arranged with spring 4 on threaded rod 3, and this spring 4 is between briquetting 5 and crossbeam 6.

The course of work of the present utility model: bell-mouthed uncovered part 2 be located on horn mouth mould 10, upwards promote threaded rod 3, tail pipe part 1 be located in the upper end of uncovered part 2 afterwards, then puts down threaded rod 3 top of tail pipe part 1 is inserted in the jack of briquetting 5.The elastic force that relies on spring 4 to provide, closed butt joint between tail pipe part 1 and uncovered part 2.Starter motor 15 afterwards, and rotating disk 9 drives horn mouths rotation, in the integrally rotated while by manually welding.
