Description

Technical Field

[0001] The present application relates to the technical field of automobile exhaust bellows production, and in particular to a mesh sleeve fixing device for automobile exhaust bellows production. Background Art

[0002] Automobile exhaust bellows, also known as automobile exhaust pipe hose, is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, making the entire exhaust system flexibly connected, thereby reducing vibration and noise, facilitating installation and extending the life of the exhaust muffler system.

[0003] Automobile exhaust bellows include bellows and mesh sleeve. The mesh sleeve can improve the strength and compression and torsional resistance of the bellows.

[0004] In the prior art, when installing the mesh sleeve, a round buckle is generally put on the outer wall of the mesh sleeve at the end of the corrugated pipe first, and then it is placed on the expansion and rounding machine for expansion and rounding, so that the mesh sleeve and the corrugated pipe can be fixed together, and the above action is repeated at the other end. The whole process needs to be repeated twice, the labor intensity of the staff is high, and the production efficiency is low.

[0005] Therefore, in order to improve production efficiency, it is urgent to develop a semi-automatic production device that can improve production efficiency but has low cost. Summary of the Invention

[0006] The purpose of this application is to provide a mesh sleeve fixing device for the production of automobile exhaust bellows to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present application provides a mesh sleeve fixing device for automobile exhaust bellows production, which adopts the following technical solutions: A mesh sleeve fixing device for automobile exhaust bellows production includes a workbench and a flaring and rounding machine disposed on the workbench. The workbench is provided with a positioning mechanism and a clamping mechanism. A slide and a driving cylinder are symmetrically provided on both sides of the clamping mechanism. The slide is slidably connected to the workbench. The driving cylinder is fixed to the workbench and is used to drive the slide to move. The slide is mounted with the flaring and rounding machine. The clamping mechanism includes a Y-axis linear movable slide, a mounting frame, a base, a pressure block and a pressing cylinder. The Y-axis linear movable slide is fixed on the workbench, the mounting frame is fixed on the slide of the Y-axis linear movable slide, the base is fixed on the mounting frame, the pressing cylinder is vertically fixed on the mounting frame, the pressure block is arranged on the top of the base, and the pressing cylinder is used to drive the pressure block to rise and fall; The positioning mechanism includes a symmetrically arranged positioning component, which includes a slide rail, a vertical rod, a lifting block and a spring. The slide rail is fixed to the workbench and moves the slide linearly parallel to the Y-axis. A slider is slidably connected to the slide rail, and the vertical rod is vertically fixed to the slider. The lifting block is movably arranged on the vertical rod. One end of the spring is fixed to the bottom of the lifting block, and the other end of the spring is fixed to the slider. A synchronization rod is fixed between the lifting blocks on both sides, and a stop groove for placing the corrugated pipe is provided on the surface of the lifting block.

[0008] The base and the surface of the pressing block are both provided with arc grooves, and an anti-slip pad is detachably fixed in the arc groove.

[0009] Preferably, the workbench is also provided with a unloading mechanism, which includes an X-axis linear moving slide, a lifting cylinder, a support platform, a servo motor, a rotating block and a support rod. The X-axis linear moving slide is fixed on the workbench, the lifting cylinder is vertically fixed on the slide of the X-axis linear moving slide, the support platform is arranged on the top of the piston rod of the lifting cylinder, the servo motor is fixed on the support platform, the rotating block is rotatably connected to the support platform, the rotating block is circular, and a number of teeth are evenly opened on the rotating block, and the teeth are arranged in an arc shape. The support rod is fixed on the rotating block, and a gear meshing with the teeth is fixed on the output shaft of the servo motor.

[0010] By adopting the above technical solution and providing a blanking mechanism, after the exhaust bellows is expanded and rounded, the clamping cylinder in the clamping mechanism drives the pressure block to rise. At this time, the X-axis linear moving slide drives the support rod to insert into the exhaust bellows, and the servo motor drives the rotating block to rotate. The rotating block drives the support rod to tilt upward, and the lifting cylinder drives the support platform to move upward, so that the exhaust bellows can be lifted from the base. The X-axis linear moving slide drives the exhaust bellows away from the clamping mechanism, and then the servo motor drives the support rod to tilt downward again, and the exhaust bellows falls from the discharge port under the action of gravity.

[0011] A discharge port is provided on the workbench at a position corresponding to the support rod.

[0012] Preferably, a telescopic sleeve is provided inside the spring, the top end of the telescopic sleeve is fixed to the lifting block, and the bottom end of the telescopic sleeve is fixed to the sliding block.

[0013] By adopting the above technical solution, the setting of the telescopic sleeve can, on the one hand, provide guiding performance for the lifting block, and on the other hand, reduce the vibration amplitude of the spring, so that the lifting block can be quickly reset and hovered.

[0014] Preferably, in order to ensure that the pressing block can move vertically up and down, the pressing block is slidably connected to the mounting frame.

[0015] To sum up, the present application includes at least one of the following beneficial technical effects: the mesh sleeve fixing device for the production of automobile exhaust bellows is provided with a clamping mechanism, a positioning mechanism and symmetrically arranged expanding and rounding machines on both sides of the clamping mechanism. The positioning mechanism can place the bellows covered with the mesh sleeve in the center, and use the clamping mechanism to transport the bellows to the expanding and rounding machine. The expanding and rounding machines on both sides can expand and round both ends of the bellows at one time, greatly improving production efficiency. During the entire process, the staff only needs to perform loading actions, which greatly reduces the labor intensity of the staff. BRIEF DESCRIPTION OF THE DRAWINGS
