Description

Technical Field

[0001] The utility model relates to the field of clutch welding devices, and relates to a welding device for laminated hole-blocking sheets for clutches. Background Art

[0002] The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox. During the driving of the vehicle, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and the gearbox, so as to cut off or transmit the power input from the engine to the transmission. The existing hole-blocking sheets for automotive clutches are all clamped in the holes by a clamping method. The materials of the laminated hole-blocking sheets mainly include high-temperature resistant rubber materials, thin steel sheets, and metal components that may be used for connectors. The rubber disk one and the rubber disk two are made of high-temperature resistant rubber materials. The thin steel sheets include a steel ring one and a steel ring two, which are arranged between the rubber disks to play a supporting role, prevent the rubber disks from being distorted and deformed, and at the same time enhance the structural stability of the hole-blocking sheet.

[0003] The connection between the thin steel sheet and the rubber disk usually adopts the following several methods: using mechanical elements such as bolts, screws or rivets to fix the thin steel sheet on the rubber disk; using an adhesive suitable for bonding rubber and metal to paste the thin steel sheet on the rubber disk; or connecting the metal sheet and the rubber through special welding techniques (such as laser welding or ultrasonic welding). Welding can provide very high connection strength, sometimes even stronger than the materials being connected themselves. Welding can form a sealed connection to prevent the penetration of liquids or gases, and is suitable for applications that require sealing.

[0004] However, there are the following deficiencies in the welding process: misalignment of the welding position: if the thin steel sheet and the rubber disk are not accurately aligned before welding, it will lead to inaccurate welding positions, affecting the structural stability and sealing performance; insufficient welding tightness: if there is a gap between the thin steel sheet and the rubber disk, a good welded joint may not be formed. Summary of the Utility Model

[0005] The utility model provides a welding device for laminated hole-blocking sheets for clutches to solve the problems of the prior art.

[0006] The object of the present utility model can be achieved by the following technical solutions: A welding device for a laminated hole plugging sheet for a clutch includes: a base, a turntable, a driving mechanism, a lower limiting component, an upper limiting component, a pressing component, and a rotary driving component. The turntable is rotatably arranged at the upper end of the base and rotates through the driving mechanism. Both the lower limiting component and the upper limiting component include an inner sleeve, an outer sleeve, and a push rod.

[0012] Compared with the prior art, the beneficial effects of the welding device for a laminated hole plugging sheet for a clutch of the present utility model are as follows:
