Embodiment

[0035]First, the extension of the piston rod of the first cylinder 1 drives the movable plate 13 to move to the right, and the bushing 21 and the plug 6 extend into the joint of the exhaust pipe. When the second connecting piece 4 touches the second sensor 5, it will move The plate 13 stops moving, and then the piston rod of the second cylinder 12 is extended to control the drive shaft 24 to move to the right, and the extrusion parts 28 on the drive shaft 24 also move to the right together. The reduced taper makes the extrusion part 28 continuously squeeze the positioning block 26, and the positioning block 26 moves along the positioning hole until the four positioning blocks 26 are closely attached to the inner hole wall of the exhaust pipe joint, realizing the exhaust The positioning and locking function of the inner hole of the pipe joint portion is to realize the internal positioning of the exhaust pipe, and at the same time, the drive shaft 24 drives the plug 6 to extend i...

Abstract

The invention relates to a continuous tensioning and positioning device applied to an air inlet end of an exhaust pipe. The device comprises a bottom plate, a plug and a movable plate. A shaft sleeveis horizontally arranged at a middle part of an upper end of the movable plate. The shaft sleeve is sleeved with an outer positioning frame which is slidingly connected to a first guide rail transversely arranged on the upper end of the movable plate. The left side of the shaft sleeve is equipped with a guide seat. The front and back sides of the guide seat are slidingly equipped with driving plates. The right ends of the two driving plates are equipped with fixed plates. A right end of the guide seat is equipped with a second cylinder whose one end is axially connected to a driving shaft. Thedriving shaft is connected to a plug and is slidingly equipped with a circular sealing plate between the plug and the shaft sleeve. A plurality of connection rods are uniformly distributed on the circular sealing plate and the fixed plates around the driving shaft. The middle part of the driving shaft is equipped with a pressing part. The side wall of the shaft sleeve is provided with a tensioning device matched with the pressing part. According to the continuous tensioning and positioning device, the stable positioning and sealing are achieved by continuous tensioning.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust pipe positioning, in particular to a continuous tightening positioning device applied to the intake end of the exhaust pipe. Background technique [0002] With the rapid development of the automobile industry, the output of automobile exhaust pipes is also increasing year by year. Although the output is large, the quality of automobile exhaust pipes still needs to be guaranteed, so the requirements for the inspection tools of automobile exhaust pipes are also increasing. high. [0003] When inspecting automobile exhaust pipes, it is necessary to detect the air tightness of the exhaust pipes. At present, most of the inspection tools are positioned by cylinders, but the size of the product is not easy to control, resulting in unstable product positioning, which directly affects the detection accuracy. Contents of the invention [0004] The technical problem to be solved by the present ...
