Description

Technical Field

[0001] This utility model relates to the field of flywheel clamping fixture technology, and in particular to a flywheel clamping fixture with simplified operation. Background Technology

[0002] The flywheel of a stamping press is a disc-shaped part installed at the rear end of the crankshaft of the stamping press. It has a large moment of inertia and its core function is to store rotational kinetic energy and release huge energy at the moment of stamping to ensure the smooth completion of the stamping action.

[0003] During flywheel machining, its bottom needs to be clamped by a fixture, while the top is cut. Conventional clamping for large flywheels often requires turning multiple screws to push a fixing block inward to hold the flywheel in place. For example, a flywheel housing clamping and positioning fixture as described in application number CN202422418390.6... Figure 1 The first screw 2 is rotated to push the clamping plate 3 inward.

[0004] However, when dealing with larger flywheels, this type of structure requires multiple (e.g., five to six) clamping plates for holding, and each first screw needs to be turned individually. During the turning process, the chassis needs to be rotated or the position needs to be manually rotated for setting, which increases the number of steps and prolongs the setup time. Utility Model Content

[0005] The purpose of this invention is to provide a flywheel clamping fixture that simplifies operation.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] The simplified flywheel 14 clamping fixture includes a base 1, which is fixed to the ground. An annular groove 2 is provided on the base 1, and a circular groove 3 is provided within the annular groove 2. A connecting groove 4 is provided between the annular groove 2 and the circular groove 3. An inclined guide inner wall 41 is provided on the outer side of the connecting groove 4. The connecting groove 4 has an inclined structure with a larger opening at the outer end and a smaller opening at the inner end.

[0019] An annular ring 5 is provided within the annular groove 2, and a full circle of external teeth 51 is provided on the outer wall of the annular ring 5. A transverse groove 6 is provided on the base 1, and the inner wall of the transverse groove 6 communicates with the annular groove 2. A transverse worm 7 is provided within the transverse groove 6, and the transverse worm 7 meshes with the external teeth 51. A rotating handle is provided at one end of the transverse worm 7, and the annular ring 5 can be rotated by turning the rotating handle. The transverse worm 7 can be controlled by a motor or by using traditional tools. When using traditional tools such as wrenches, a regular hexagonal block is preferably provided at the front end of the transverse worm 7 to facilitate operation with a wrench. Since the transverse worm 7 extends relative to the tangential direction of the rotating ring, a portion of the base 1 at the outer position of the transverse worm 7 can be cut off to facilitate the operation of the transverse worm 7 by the operator using tools.

[0020] Multiple extension blocks 8 are rotatably provided on the inner wall of the annular ring 5, extending from the connecting groove 4 into the circular groove 3 and abutting against the outer wall of the flywheel 14, thereby clamping the flywheel 14 in the circular groove 3 of the suspended device.

[0021] In this design, the bottom surface of the annular groove 2 is provided with multiple evenly arranged lifting columns 10, and the bottom surface of the annular ring 5 is provided with a track groove 11. The ends of the lifting columns 10 are embedded in the track groove 11. When the annular ring 5 is driven to rotate, it rotates along the path formed by the lifting columns 10, ensuring that the rotation process is controllable. Multiple oil injection grooves 12 are provided on the annular ring 5, connected to the upper ends of the lifting columns 10. These oil injection grooves 12 increase the lubrication between the two, thereby ensuring the smoothness of the annular ring 5's rotation.

[0022] On the other hand, multiple strip blocks 13 are strung across the base 1 via screws, and multiple arc-shaped grooves 52 are provided on the upper surface of the annular ring 5. The pressure block 131 is embedded in the groove 52. The strip blocks 13 can press down on the annular ring 5, avoiding problems such as one-sided protrusion of the annular ring 5 and ensuring its stability during rotation. At the same time, the pressure block 131 embedded in the groove 52 can also guide the rotation of the annular ring 5. Among them, the oil filling groove 12 is preferably located at the far corner of one side of the groove 52. When the rotating ring is in the initial position, the oil filling groove 12 is directly opposite the lifting column 10. This arrangement can reduce the clogging of the oil filling groove 12 by dust.

[0023] The extension block 8 includes a block body 81 with a groove 82. A rotating column 83 is disposed within the groove 82. The upper inner wall of the groove 82 abuts against the upper surface of the annular ring 5, and the lower inner wall abuts against the lower surface of the annular ring 5. The rotating column 83 passes through the annular ring 5. An arc-shaped portion 811 is disposed on the outer side of the block body 81. The arc-shaped portion 811 cooperates with the inclined guide inner wall 41 on the outer side of the extension block 8, facilitating the movement of the extension block 8 inward along the connecting groove 4 to abut against the outer wall of the flywheel 14. The inclined structure of the connecting groove 4, with a large opening at the outer end and a small opening at the inner end, can prevent the extension block 8 from shaking during contact (as shown in the figure, the right side can hold the extension block 8), ensuring stability when clamping the flywheel 14.

[0024] The upper end of the extension block 8 is vertically equipped with a clamping block 9. The lower bottom surface of the clamping block 9 abuts against the surface of the base 1, and the inner side of the clamping block 9 abuts against the outer wall of the flywheel 14. The clamping block 9 can expand the clamping area of ​​the flywheel 14 from above, thereby maintaining the stability of the flywheel 14 when it is being cut.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
