Description

Technical Field

[0001] The utility model belongs to the technical field of exhaust pipe welding, in particular to a positioning device for exhaust pipe welding. Background Art

[0002] The exhaust pipe is installed between the engine exhaust manifold and the muffler, making the entire exhaust system flexibly connected, thereby reducing vibration and noise, facilitating installation and extending the life of the exhaust and muffler system. Exhaust pipes are mainly used for light vehicles, micro vehicles, buses, and motorcycles. The exhaust pipe structure is a double-layer corrugated pipe covered with a steel wire mesh sleeve, with straight-edge sections at both ends covered with a clamping ring. In order to achieve a better muffler effect, the bellows can be equipped with an expansion joint or a mesh sleeve.

[0003] At present, before welding the exhaust pipe on the refrigerator refrigeration compressor, the exhaust pipe needs to be fixed and clamped. The existing method of fixing and clamping the exhaust pipe generally adopts an arc-shaped clamping plate relatively arranged on the outside of the exhaust pipe, and the outer peripheral side of the exhaust pipe is fixed by the arc-shaped clamping plate. However, if the clamping force is too large, it is easy to cause deformation of the exhaust pipe, thereby affecting the quality after welding. If the clamping force is too small, the clamping force is insufficient, thereby affecting the stability of the exhaust pipe fixation clamping.

[0004] To this end, we provide a positioning device for exhaust pipe welding to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a positioning device for exhaust pipe welding, which adjusts the distance between the arc-shaped clamping plates by moving the arc-shaped clamping plates closer to or farther away from the axis of the disk, so that the arc-shaped clamping plates are suitable for clamping and fixing exhaust pipes of different diameters, thereby improving applicability and convenience of use. The arc-shaped clamping plates are clamped on the peripheral side surfaces of the exhaust pipe ends, avoiding the traditional upward and downward directions of fixing and clamping the outer peripheral side surfaces of the exhaust pipe, causing deformation of the exhaust pipe, thereby affecting the quality of the exhaust pipe after welding, and solving the problem of deformation caused by the existing exhaust pipe fixing and clamping, which affects the welding quality.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0013] The utility model is further configured such that protective pads are fixedly mounted on two opposite side surfaces of two adjacent arc-shaped clamping plates.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model drives the rod, the slide plate and the arc-shaped clamping plate to approach or move away from the axis of the disc by rotating the toothed disc clockwise or counterclockwise under the guidance of the arc-shaped groove, thereby adjusting the distance between the arc-shaped clamping plates, making the arc-shaped clamping plates suitable for clamping and fixing exhaust pipes of different diameters, improving applicability and convenience of use, and the arc-shaped clamping plates are clamped on the peripheral side of the end of the exhaust pipe, avoiding the traditional fixing and clamping of the outer peripheral side of the exhaust pipe in the up and down directions, causing the exhaust pipe to deform, thereby affecting the quality of the exhaust pipe after welding.

One side of the slide plate 13 is fixedly connected with a push rod 15 that passes through the toothed disc 12, and one side of the slide plate 13 close to the toothed disc 12 is symmetrically and parallelly provided with an arc-shaped clamping plate 17, and the opposite sides of the two adjacent arc-shaped clamping plates 17 are fixedly installed with protective pads, and the opposite sides of the two toothed discs 12 are fixedly connected with a motor 18, and the driving end of the motor 18 is fixedly connected with a gear 19 that meshes and matches with the toothed disc 12, and one side of the toothed disc 12 is provided with a plurality of arc-shaped grooves 22 that match with the push rod 15, and the top of the base 1 is symmetrically provided with guide grooves 3 that match with the moving plate 2.
