Description

Technical Field

[0001] The utility model relates to the technical field of flywheel boring processing, in particular to an auxiliary clamping tool for boring automobile cast iron flywheels. Background Art

[0002] An automotive flywheel is a disc-shaped component that stores energy and inertia outside the engine's power stroke. During production, the central through-hole of the flywheel must be bored. Boring involves further processing a forged, cast, or drilled hole. This process can increase the diameter of the flywheel through-hole, improve accuracy, reduce surface roughness, and effectively correct any misalignment of the original hole axis.

[0003] An existing patent publication number, CN220463010U, describes an auxiliary device for boring automobile flywheels. This device is designed to rotate a drive rod between two slots defined at the top of a turntable. When a hexagon socket bolt drives the drive rod to rotate, the two sliding parts and the clamping plate move toward each other, causing the clamping plate to tightly abut the sidewalls of the flywheel body, thereby clamping and securing the flywheel body. However, during the boring process, the flywheel body is prone to jitter. This auxiliary device, relying solely on the clamping plate for clamping, is unable to ensure stable fixation of the flywheel body. This can affect the quality of the boring process, leading to failure of the flywheel boring operation and resulting in economic losses. Utility Model Content

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figures 1 to 4As shown, an auxiliary clamping tool for boring automobile cast iron flywheels includes a workbench 100, wherein the workbench 100 is provided with a mounting groove 101, and a bidirectional screw rod 103 is rotatably provided in the mounting groove 101, and two adjusting blocks 108 symmetrically arranged along the central axis of the workbench 100 are threadedly connected to the bidirectional screw rod 103, and a clamping block 106 is fixed on the adjusting block 108. A flywheel body 105 abutting against the side walls of the two clamping blocks 106 is placed on the workbench 100, and a guide rod 102 arranged parallel to the bidirectional screw rod 103 is fixed in the mounting groove 101, and the guide rod 102 is slidably connected to the adjusting block 108. The clamping block 106 is provided with an anti-jump mechanism 200 for preventing the flywheel body 105 from jumping, and a motor 104 is fixed on the side wall of the workbench 100, and the output end of the motor 104 is transmission-connected to the end of the bidirectional screw rod 103.

[0018] The motor 104 is used to drive the bidirectional screw rod 103 to rotate. Since the bidirectional screw rod 103 is threadedly connected to the adjustment block 108, and the adjustment block 108 is symmetrically arranged along the central axis of the workbench 100, the rotation of the bidirectional screw rod 103 will cause the two adjustment blocks 108 to move toward or away from each other. According to the size of the flywheel body 105, the position of the adjustment block 108 is adjusted until the clamping block 106 is tightly abutted against the side wall of the flywheel body 105, thereby achieving stable clamping of the flywheel body 105. It can be flexibly adjusted according to the size of the flywheel body 105, is suitable for flywheels of different sizes, and enhances the versatility and flexibility of the tooling. The guide rod 102 ensures the stability and linearity of the adjustment block 108 during movement.

[0019] In this embodiment, the anti-jump mechanism 200 includes a moving groove 210 provided on the clamping block 106, a moving block 204 is movably provided in the moving groove 210, and the moving block 204 is provided with two racks 205 symmetrically arranged along its axis, the clamping block 106 is provided with a groove 209 communicating with the moving groove 210, a rotating shaft 203 is rotatably provided in the groove 209, a pressure plate 201 and a gear 202 are fixed on the rotating shaft 203, the gear 202 is meshed with the rack 205, a butt joint 208 is fixed on the moving block 204, a limiting groove 206 is provided at the bottom of the moving groove 210, a limiting block 207 is slidably provided in the limiting groove 206, the top of the limiting block 207 is fixedly connected to the bottom of the moving block 204, a side plate 211 is fixed on the moving block 204, and a spring 212 is provided between the side plate 211 and the clamping block 106.

[0020] When the clamping block 106 approaches the flywheel body 105, the abutment 208 contacts the flywheel body 105, and the abutment 208 is squeezed to move away from the flywheel body 105, driving the moving block 204 to move along the moving groove 210, and the meshing connection between the gear 202 and the rack 205 drives the gear 202 to rotate, thereby using the rotating shaft 203 to drive the pressure plate 201 to rotate, so that the pressure plate 201 is pressed to the surface of the flywheel body 105, further enhancing the stability of the clamping, preventing the flywheel body 105 from jumping during the boring process, and allowing the boring operation to be carried out accurately, thereby improving the processing quality and efficiency.

[0021] In this embodiment, a wear-resistant pad 107 is provided on the surface of the clamping block 106 that contacts the flywheel body 105 .

[0022] The wear-resistant pad 107 is provided to reduce friction and wear during the clamping process and ensure the integrity of the surface of the flywheel body 105.

[0023] Working process and principle: When using this device, place the tooling in the work area to ensure that the workbench 100 is stable and fixed, place the flywheel body 105 on the workbench 100 so that it is located between the two clamping blocks 106, start the motor 104, and use the motor 104 to drive the bidirectional screw rod 103 to rotate. Since the bidirectional screw rod 103 is threadedly connected to the adjustment block 108, and the adjustment block 108 is symmetrically arranged along the central axis of the workbench 100, the rotation of the bidirectional screw rod 103 will cause the two adjustment blocks 108 to move toward or away from each other. According to the size of the flywheel body 105, the position of the adjustment block 108 is adjusted until the clamping block 106 is tightly abutted against the side wall of the flywheel body 105, thereby achieving stable clamping of the flywheel body 105. When the clamping block 106 approaches the flywheel body 105, the abutment 208 contacts the flywheel body 105, and the abutment 208 is squeezed away from the flywheel. The main body 105 moves in the direction of movement, driving the moving block 204 to move along the moving groove 210, and the meshing connection between the gear 202 and the rack 205 drives the gear 202 to rotate, thereby using the rotating shaft 203 to drive the pressure plate 201 to rotate, so that the pressure plate 201 is pressed to the surface of the flywheel body 105, further enhancing the clamping stability, preventing the flywheel body 105 from jumping during the boring process, so that the boring operation can be carried out accurately, improving the processing quality and efficiency. After the flywheel body 105 is clamped and fixed, the boring tool is used to perform accurate boring operation on the flywheel body 105. After the boring operation is completed, the motor 104 is used to drive the clamping block 106 away from the flywheel body 105. At the same time, the spring 212 is reset to drive the moving block 204 to move out of the moving groove 210, thereby releasing the pressing effect of the pressure plate 201 on the flywheel body 105, making it convenient to take the flywheel body 105.

[0024] It is understood from common technical knowledge that the present invention may be implemented through other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
