Description

Technical Field

[0001] The utility model relates to a welding fixture for a clutch support ring. Background Art

[0002] The clutch support ring is an important component of the clutch. It can serve as a fulcrum when the clutch's diaphragm spring undergoes elastic deformation, ensuring that the diaphragm spring can evenly transmit pressure to the pressure plate and flywheel, thereby achieving the engagement and disengagement of the clutch. During the production of the clutch support ring, it is usually necessary to use a coiling machine to wind the wire into a coil shape, and then use a butt welding machine to weld the two movable ends of the support ring together. During the welding process, the support ring needs to be fixed with a clamp to prevent the support ring from shifting in position during the welding process.

[0003] The existing clutch support ring welding fixture usually installs the welding electrode directly on the clamping plate. When the clamping plate clamps the support ring, the welding electrode contacts the support ring and energizes it, thereby causing the two movable ends of the support ring to heat up and weld together. However, the welding electrode directly installed on the clamping plate lacks protection, which makes the operator's hands easily come into contact with the welding electrode and get burned. Therefore, it is necessary to develop a clutch support ring welding fixture to solve the above problem. Utility Model Content

[0004] The purpose of the present utility model is to provide a welding fixture for a clutch support ring to solve the problems raised in the above background technology.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0019] See Figures 1 to 5The welding fixture of a clutch support ring shown includes a frame 11, and a bidirectional threaded rod 12 is rotatably arranged between the two inner walls of the frame 11. The bidirectional threaded rod 12 is provided with two sections of threads in opposite directions, and the two threaded sections of the bidirectional threaded rod 12 are provided with a moving block 14, and the two moving blocks 14 are provided with a clamping assembly 15. Slide rail assemblies 18 are provided on the two outer walls of the frame 11, and a U-shaped protective frame 16 is provided between the two slide rail assemblies 18. The U-shaped protective frame 16 is provided with a window 17. The slide rail assembly 18 includes a dovetail groove guide rail 19, and the dovetail groove guide rail 19 is fixedly set on the outer wall of the frame 11. A metal slider 20 is slidably set on the dovetail groove guide rail 19, and the metal slider 20 is connected to the U-shaped protective frame 16 by bolts.

[0020] Furthermore, a magnet strip 1 21 is provided at the upper end of the dovetail groove guide rail 19, and a magnet strip 2 22 is provided at the lower end of the dovetail groove guide rail 19; when the metal slider 20 is located at the upper part of the dovetail groove guide rail 19, the magnet strip 1 21 attracts the metal slider 20 by magnetic force, so that the U-shaped protective frame 16 is stably located on the upper side of the two clamping components 15, and the clamping components 15 are not blocked by the U-shaped protective frame 16, thereby facilitating the inspection and maintenance of the clamping components 15; when the metal slider 20 is located at the lower part of the dovetail groove guide rail 19, the magnet strip 22 attracts the metal slider 20 by magnetic force, so that the U-shaped protective frame 16 is stably located on the front side of the two clamping components 15. When clamping the support ring, the support ring is sent through the window 17 and clamped between the two clamping components 15. During the entire operation, the U-shaped protective frame 16 forms a protection on the front side of the two clamping components 15 to prevent the operator's hands from touching the electrode plate 27 and being burned.

[0021] Furthermore, the clamping assembly 15 includes a U-shaped seat 23, which is fixed on the moving block 14. A sliding rod 24 is provided between the two side walls of the U-shaped seat 23. A clamping plate 1 25 and a clamping plate 2 26 are provided on the sliding rod 24. Both clamping plate 1 25 and clamping plate 2 26 are provided with electrode plates 27.

[0022] Furthermore, the first clamping plate 25 is connected to the U-shaped seat 23 by bolts, the second clamping plate 26 is slidably arranged on the slide rod 24, and an electrically controlled telescopic rod 28 is provided between the second clamping plate 26 and the side wall of the U-shaped seat 23.

[0023] Furthermore, a motor 13 is provided on one side wall of the frame 11, and the output shaft of the motor 13 is connected to the bidirectional threaded rod 12; starting the motor 13 causes the bidirectional threaded rod 12 to rotate, and according to the forward and reverse rotation of the motor 13, the two moving blocks 14 can be moved closer to or away from each other.

[0024] The working principle of the present invention is that when the clutch support ring is clamped for welding, when the metal slider 20 is located at the lower part of the dovetail groove guide rail 19, the second magnet strip 22 attracts the metal slider 20 through magnetic force, so that the U-shaped protective frame 16 is stably located at the front side of the two clamping components 15. At this time, the window 17 is aligned with the gap between the electrode plate 27 on the clamping plate 1 25 and the electrode plate 27 on the clamping plate 2 26. Then the support ring is placed flat through the window 17 so that the two movable ends of the unwelded support ring are respectively located between the two groups of electrode plates 27. Then the electric-controlled telescopic rod 28 is started to extend so that the clamping plate 26 rises, so that the electrode plate 27 on the clamping plate 1 25 and the electrode plate 27 on the clamping plate 2 26 clamp the movable end of the support ring. Then the motor 13 is started to rotate the bidirectional threaded rod 12 , so that the two moving blocks 14 are close to each other, so that the two clamping components 15 are close to each other, so that the two movable ends of the unwelded support ring are close to each other and docked together, and then the electrode plate 27 is energized to make the two movable ends of the support ring heat up, thereby welding the two movable ends of the support ring together; when the clamping component 15 needs to be inspected and maintained, the U-shaped protective frame 16 is pulled upward, and the metal slider 20 slides upward along the dovetail groove guide rail 19 until the metal slider 20 is in contact with the magnet bar 121, and the magnet bar 121 attracts the metal slider 20 through magnetic force, so that the U-shaped protective frame 16 is stably docked on the upper side of the two clamping components 15. At this time, the clamping component 15 is not blocked by the U-shaped protective frame 16, thereby facilitating the inspection and maintenance of the clamping component 15.

[0025] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that do not require creative work should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
