Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a pushing clamp for machining and manufacturing a generator end cover. Background Art

[0002] During the motor manufacturing process, the motor end cover needs to be machined. First, the bearing chamber positioning core is installed on the side of the workbench, and the end cover bearing chamber is placed on the bearing chamber positioning core. Then, the pressure plate is pre-tightened to the end cover through the clamping nut. A level is placed on the bottom foot plane of the end cover, and the angle of the end cover is adjusted to ensure that the level reading is in the middle position. Finally, the clamping nut is tightened with a wrench, and the bottom foot plane of the end cover is started to be planed and milled. Before processing, it needs to be clamped with a fixture. The generator end cover is an irregular shape, and the processing amount is relatively large. Therefore, the clamping adjustment is performed during the subsequent clamping. However, it is not easy to adjust the clamping position when the end cover is clamped, which makes it difficult to adjust the clamping position. End covers of the same shape are prone to loosening when clamped, which increases the difficulty of subsequent end cover processing. After the clamp and the end cover are clamped, the wear is likely to increase as the processing progresses, resulting in loose clamping, causing the end cover to rotate on the clamp, reducing the accuracy of end cover processing, making it difficult to install some end covers, resulting in insufficient contact when the subsequent end cover is clamped, and the contact surface of the end cover is damaged by the pressure generated during processing. At the same time, there is a possibility that the clamped generator cover may fall off and fall into the machine tool to damage the equipment. At the same time, when the clamp is installed on the equipment, pushing the cover will generate impact force, which will affect the shape of the cover or cause damage to the clamp head over time.

[0011] 1. This kind of pushing clamp for processing and manufacturing the generator end cover is provided with a slide bar, a telescopic spring and a cross plate. When the clamp pushes the motor cover, the cross plate can be squeezed and compressed backward, which will not affect the clamping of the machine cover. After clamping the machine cover, the cross plate will be reset to its original position under the action of the telescopic spring, which will not affect the clamping of the machine cover. At the same time, it can be reset after clamping to avoid the possibility of the machine cover falling into the machine tool, which has strong practicality.

[0012] 2. This type of pushing clamp for processing and manufacturing the generator end cover has a buffer mechanism. When the clamp pushes the machine cover, it will not contact the machine cover in the traditional direct extrusion method, but will mitigate the contact by reducing the impact force after contacting the machine cover. On the one hand, it can reduce damage to the clamp, and on the other hand, it also reduces damage to the machine cover, avoiding frequent replacement of the clamp and increasing processing costs.
