Description

Technical Field

[0001] The invention belongs to synchronizer friction ring processing equipment, and in particular relates to friction ring bonding equipment. Background Art

[0002] Synchronizer shifting relies on the synchronizer to achieve synchronization by combining the inertia torque between the ring gear and the friction ring. Friction rings often require external bonding of friction-resistant material to increase their wear resistance. Synchronizer friction rings have unique shapes and structures and come in a wide variety of varieties. Currently, friction material bonding primarily relies on manual labor, which is inefficient, labor-intensive, and has high labor costs. Furthermore, during the manual bonding process, the friction-resistant material cannot be evenly pressed, making it difficult to guarantee a good bond. Furthermore, when using adhesives that require preheating the friction ring before bonding, separate heating equipment is required, increasing material transfer time and reducing processing efficiency. Summary of the Invention

[0003] The main purpose of the present invention is to solve the technical problems in the prior art of relying on manual work to bond friction materials on the surface of friction rings, which have low work efficiency, high labor intensity, high labor costs, difficult to ensure bonding effect, and difficulty in providing a suitable bonding temperature for high-temperature resistant adhesives, and to provide a friction ring bonding device.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A friction ring bonding device is characterized in that it comprises a platform, a chuck and a bonding unit;

[0006] The chuck is mounted on the platform and is driven to rotate by a chuck motor fixed on the platform;

[0007] The bonding unit includes a slide, a guide plate and a pressure wheel; the slide is installed on the outside of the platform, and the slide cooperates with the first guide rail provided on the platform through a first slider provided at the bottom, and the first guide rail is provided in a direction perpendicular to the movement direction of the platform; the guide plate and the pressure wheel are installed side by side on the slide, and the guide plate, the pressure wheel and the chuck are at the same height, and a guide groove for the friction material to pass through is provided on the guide plate.

[0008] Furthermore, it also includes a lifting drive unit and a heating device;

[0009] The lifting drive unit drives the platform to perform lifting motion;

[0010] The heating end of the heating device is located above the chuck.

[0011] Furthermore, it also includes a base;

[0012] The lifting drive unit includes a motor and a screw driven to rotate by the motor; the motor is installed on the base through a bracket; a second guide rail is provided on the bracket in a direction parallel to the screw, and a second slider adapted to the second guide rail is connected to the platform, and the second slider is sleeved on the screw and cooperates with the screw.

[0013] Furthermore, the heating device is a high-frequency heating device, the heating coil of the high-frequency heating device is located above the chuck, and the control cabinet of the high-frequency heating device is fixed on the base.

[0014] Furthermore, the chuck motor, the control cabinet of the high-frequency heating device and the cables of the motor are assembled in the tank chain trough and connected to the electric control cabinet.

[0015] Furthermore, an adjustable support seat is provided at the bottom of the base.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The friction ring bonding device of the present invention comprises a friction ring to be bonded with friction material, mounted on a chuck. A slide moves along a first guide rail, driving a guide plate and a pressure roller to move synchronously until the pressure roller contacts the friction ring on the chuck. A chuck motor drives the chuck to rotate, driving the friction ring on the chuck to rotate synchronously. Simultaneously, the friction material passes through a guide groove on the guide plate and is positioned at the contact point between the pressure roller and the friction ring. The friction material, coated with adhesive on one side, is bonded to the friction ring. The rotation of the friction ring drives the pressure roller to rotate synchronously in the opposite direction, thereby bonding the friction material along the outer periphery of the friction ring. This bonding device requires only manual feeding of the friction material through the guide plate. The friction material is accurately positioned and pressed against the surface of the friction ring by the passive rotation of the pressure roller, achieving bonding between the friction material and the friction ring. This replaces intensive manual bonding work, improves bonding quality and effectiveness, and reduces the operator's exposure time to harmful adhesive substances. This device improves bonding efficiency and the stability of bonding quality, reduces operator labor intensity, effectively saves labor costs, and helps reduce the production cost of synchronizer friction rings.

[0018] 2. The present invention is also equipped with a heating device and a lifting drive unit, making the device suitable for friction rings that require preheating. The lifting drive unit drives the platform to rise close to the heating end of the heating device. After heating is completed, it is lowered to a certain position for the bonding process. This solves the problem of high-temperature resistant adhesives having difficulty in achieving the appropriate bonding temperature, making the device more adaptable and automated. It also saves space required for a separate heating device, improves space utilization at the site, and reduces transportation time.

[0019] 3. The lifting drive assembly of the present invention utilizes the cooperation of the lead screw and the second slider to complete the lifting drive, which is convenient to process and has a compact structure.

[0020] 4. The present invention uses a high-frequency heating device to complete heating, achieving a rapid heating effect. The heating efficiency is reduced from the current furnace heating time of 8 minutes to 1 second, effectively improving the processing efficiency.

[0021] 5. The cables in the present invention are all assembled in the tank chain duct, which improves the safety and aesthetics of the cable connection.

[0022] 6. The bottom of the base of the present invention is provided with an adjustable support seat, which is convenient for adjusting the use height of the base according to needs, and also convenient for leveling the entire equipment to avoid affecting the processing effect due to tilting of the equipment.
