[0002] Automotive bushings are accessories used on the exterior of mechanical components to achieve functions such as sealing and wear protection; they refer to rings that act as gaskets. Automotive driveshaft bushings are mainly fitted onto the automotive driveshaft to provide a connection and seal. However, current automotive driveshaft bushings have issues with the connection to the driveshaft, indicating a need for further structural improvements.

[0003] The production of automotive bushings involves several processes, including material preparation, mold making, rough machining, heat treatment, and finish machining. Rough machining involves cutting the material into the appropriate shape to facilitate subsequent finish machining. Existing technologies, such as the cutting device for automotive shock absorber bushings disclosed in CN114700859B, use a sleeve and a surrounding plate on the outer periphery of the grinding wheel to prevent dust from spreading during bushing cutting. However, this device only considers dust reduction and prevention, while the debris generated during cutting still requires subsequent shutdown for processing. The cutting of the bushing and the cleaning of dust are not synchronized, which means that the cutting efficiency of the bushing needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cutting device for shock absorber bushings for automotive transmission systems, which can simultaneously carry out the cutting, circulation and dust and debris generated during the cutting of the bushing, thereby improving the processing efficiency of the bushing.

[0024] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0025] See Figure 1-5 In one embodiment of this utility model, a cutting device for shock-absorbing bushings used in automotive transmission systems includes: a workbench 1, a cutting machine 2, a dust and debris handling mechanism 3, and a collection hopper 4 mounted on the workbench 1. The cutting machine is located above the collection hopper 4 to cut the bushing and allow the cut bushing to fall into the collection hopper 4 and flow into other processing steps. The dust and debris handling mechanism 3 is located below the collection hopper 4 to collect dust and debris generated during bushing cutting to improve the production environment. With this cutting device, the cutting, transfer, and dust / debris generated during bushing cutting can be carried out simultaneously, thereby improving the processing efficiency of the bushing.

[0026] Specifically, the workbench 1 has a square through hole running vertically through the table surface, and the front side of the through hole is provided with a clamp and a feeding device for holding the liner tube during implementation.

[0027] The cutting machine 2 includes a motor 21, a grinding wheel 22, a dust cover 23, a pressing cylinder 24, a vertical plate 25, a support plate 26, and parts such as shafts, bearings, gears, and belts necessary for the operation of the grinding wheel 22. The motor 21 is installed on the right side of the through hole, and one end of the dust cover 23 is rotatably installed on the rear side of the motor 21. The grinding wheel 22 is installed inside the dust cover 23 and located at the end away from the motor 21, while the grinding wheel 22 is located directly above the through hole. The grinding wheel 22 is connected to the output shaft of the motor 21 through bearings, gears, and belts.

[0028] The pressing cylinder 24 is installed on the rear side of the through hole and on the upper side of the grinding wheel 22 via the upright plate 25 and the support plate 26. The output end of the pressing cylinder 24 is fixedly connected to the dust cover 23. When the pressing cylinder 24 is working, it can push the grinding wheel 22 to move up and down relative to the through hole.

[0029] In one embodiment, a storage groove 251 is provided on the workbench 1 behind the through hole and below the vertical plate. The direction of the storage groove 251 is perpendicular to the displacement direction of the grinding wheel 22. The cutting machine 2 also includes a push rod 27, which is slidably disposed in the storage groove 251. When the liner is placed in the storage groove 251, the front end of the push rod 27 abuts against the liner. At this time, the distance between the front end of the push rod 27 and the landing point of the grinding wheel 22 on the workbench 1 is the length of the liner that needs to be cut. The length of the liner that needs to be cut can be adjusted by changing the position of the push rod 27.

[0030] In one embodiment, the cutting machine 2 further includes two position switches 28, which are respectively placed on the left and right sides of the storage slot 251. In this embodiment, the cutting device also includes a controller, which is connected to the motor 21, the pressing cylinder 24 and the position switches 28 by circuit. When the liner is placed in the storage slot 251 and abuts against the top rod 27, the position switch 28 sends a signal to the controller to make the motor 21 and the pressing cylinder 24 work together to achieve the purpose of cutting.

[0031] The hopper 4 includes a hopper body 41, a mesh plate 42, and a discharge plate 43. The hopper body 41 covers the lower side of the through hole, and the mesh plate 42 is placed obliquely inside the hopper body 41. The inner wall of the hopper body 41 has a discharge outlet 411, which is located at the lower end of the mesh plate 42. The discharge plate 43 is located outside the hopper body 41 and its position corresponds to the outlet 411. In this embodiment, the hopper body 41 is a bucket-shaped structure similar to a cone. The advantage of this structure is that larger particles of debris generated by the cutting of the liner can slide down the inner wall of the hopper body 41 to the bottom of the hopper body 41 for collection. In addition, after cutting, the finished liner will fall onto the mesh plate 42 and slide out of the hopper body 41 along the mesh plate 42 to be received by the next production process. It should be noted that the outlet 411 is higher than the bottom of the hopper body 41; the discharge plate 43 is set at an angle.

[0032] In one embodiment, the tilt angle of the grid plate 42 can be controlled between 30 and 60 degrees. Too gentle a tilt angle will affect the finished product of the liner sliding out, while too steep a tilt angle will cause larger particles of debris generated during cutting to slide out of the hopper body 41, affecting cleaning.

[0033] The dust and debris handling mechanism 3 includes components such as an air inlet pipe, a connecting pipe, an exhaust fan 31, a conical cylinder 32, a waste cylinder 33, a connecting shaft 34, a pulley 35, a belt 36, gears, and bearings. The connecting shaft 34 is connected to the output shaft of the motor 21 through gears and bearings. The rotating shaft of the exhaust fan 31 is connected to the connecting shaft 34 through the pulley 35 and the belt 36. When the motor 21 is running, it can drive the grinding wheel to rotate and simultaneously drive the exhaust fan 31 to work, thus achieving linkage.

[0034] The upper end of the air inlet pipe is connected to the hopper body 41, and the lower end extends into the conical cylinder 32; the waste cylinder 33 is located at the lower end of the conical cylinder 32 and is connected to the conical cylinder 32; the air inlet of the exhaust fan 31 is connected to the upper part of the conical cylinder 32 through a connecting pipe.

[0035] During the liner cutting process, the motor 21 drives the exhaust fan 31 to create negative pressure in the conical cylinder 32, the air inlet pipe, and the hopper body 41. At the same time, the airflow in the conical cylinder 32 changes from linear motion to circular motion. The dust and debris generated during the liner cutting are sucked into the hopper body 41 and then enter the conical cylinder 32 through the air inlet pipe. Most of the rotating airflow flows spirally downwards from the cylindrical body towards the cone along the wall. In addition, the dust and debris are thrown towards the wall under the action of centrifugal force. Once the dust and debris come into contact with the wall, they lose inertial force and fall along the wall due to the momentum of the downward axial velocity near the wall, entering the waste cylinder 33. The purified air is discharged outside the device through the exhaust fan 31.

[0036] This technical solution involves installing a cutting machine, a dust and debris handling mechanism, and a hopper on a workbench. The cutting machine, located above the hopper, cuts the liner and allows the cut liner to fall into the hopper and flow into other processing steps. The dust and debris handling mechanism, located below the hopper, collects the dust and debris generated during the cutting of the liner to improve the production environment. With this cutting device, the cutting, circulation, and dust and debris generated during the cutting of the liner can be carried out simultaneously, thereby improving the processing efficiency of the liner.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
