Description

Technical Field

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

[0002] An exhaust muffler is a device used to reduce or eliminate noise generated by an exhaust system. It is widely used in various industrial fields, such as electricity, petroleum, chemical industry, metallurgy, textile, papermaking, food, etc., as well as automobile exhaust systems, to reduce the noise generated during the exhaust process. The working principle of the exhaust muffler is mainly based on the large-pore pressure-reducing injection muffler principle or the porous diffusion muffler principle. Through optimized design, it achieves a highly efficient noise reduction effect. The existing positioning device cannot drive the exhaust muffler to rotate while positioning it, which makes it very inconvenient to weld and polish the surface of the exhaust muffler, and cannot quickly drive it to adjust the processing position, resulting in poor use effect. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides a positioning device for exhaust muffler processing, which effectively solves the problem that the existing positioning device cannot drive the exhaust muffler to rotate while positioning it, resulting in great inconvenience in welding and polishing the surface of the exhaust muffler.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positioning device for exhaust muffler processing, comprising a base plate, support plates are fixedly installed on both sides of the top of the base plate, a mounting groove is opened in the middle of the top of the base plate, a protective cover is fixedly installed on the bottom inside the mounting groove, a motor is fixedly installed on the bottom inside the protective cover, a steering transmission assembly is provided at the output end of the motor, a mounting cylinder is provided on the upper part of the side where the two support plates are close to each other, a mounting frame is fixedly installed on the end where the two mounting cylinders are close to each other, the motor is connected to the two mounting cylinders through a rotating transmission assembly, a cylinder is fixedly installed inside the two mounting cylinders, a clamping transmission assembly is provided at the transmission end of the two cylinders, clamping plates are provided on the upper and lower sides of the two mounting frames, and the two cylinders are connected to the four clamping plates through two clamping transmission assemblies.

[0005] The two gears are connected with each other through the two guide wheels, and the two guide wheels are connected with each other through the middle of the two support plates, and the two guide wheels are connected with each other through the middle of the two support plates.

[0006] Preferably, the two clamping transmission assemblies include transmission blocks, the two transmission blocks are fixedly installed on the transmission ends of the two cylinders, and fixed blocks are fixedly installed on the upper and lower sides of the two transmission blocks, and a sliding sleeve is fixedly installed on one end of the fixed block, and a sliding rod is inserted into the inside of the sliding sleeve, and one end of the four sliding rods is fixedly connected to the inner walls of the two mounting frames respectively, and two transmission grooves are provided inside the two transmission blocks, and transmission pins are inserted at both ends of the four transmission grooves, and moving rods are fixedly installed at both ends of the transmission pins, and the ends of the moving rods away from the transmission blocks are fixedly connected to the four clamping plates respectively, and the surface of the moving rod is sleeved with a limiting sleeve, and the limiting sleeves are fixedly connected to the two mounting frames respectively.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: when in use, the operator starts the two cylinders and simultaneously pushes the two transmission blocks to move toward each other. When the two transmission blocks move, the sliding sleeves are driven by the fixed blocks to slide along the surface of the sliding rod, thereby increasing the stability of the two transmission blocks when moving. When the two transmission blocks move, the transmission pins are pulled inward by the two transmission grooves provided therein. When the transmission pins move inward, the moving rods are pulled to slide along the inside of the limiting sleeves, thereby increasing the stability of the moving rods when moving. When the moving rods move inward, the clamping plates are pulled to clamp and position the intake pipe and the exhaust pipe at both ends of the exhaust muffler, thereby quickly completing the fixation of the exhaust muffler.

[0008] When the direction of the exhaust muffler needs to be adjusted, the operator starts the motor to drive the first bevel gear to rotate, and the first bevel gear drives the first shaft to rotate along the inside of the two first shaft sleeves through the second bevel gear. When the first shaft rotates, it drives the two first sprockets to rotate. When the two first sprockets rotate, they drive the two second sprockets to rotate through the chain. When the two second sprockets rotate, they drive the second shaft to rotate along the inside of the second shaft sleeve. When the two second shafts rotate, they drive the mounting frame to rotate through the mounting tube. When the mounting frame rotates, the exhaust muffler is driven to rotate and adjusted through the clamping plate; this allows the positioning device to conveniently drive the exhaust muffler to rotate while positioning it, making it very convenient to process the surface of the exhaust muffler.
