Description

Technical field:

[0001] The present invention relates to the technical field of motor equipment, and more particularly to an end cover processing device for an aluminum shell motor for a pump. Background technology:

[0002] In some existing motors installed in pump bodies, the end plate of the motor must be connected to the pump casing of the pump body. In order to ensure a tight connection, it is necessary to form a connecting through-hole in the middle of the wall plate of the connecting end of the pump casing, and a protrusion is formed in the middle of the front end surface of the end plate of the motor, which is inserted into the corresponding connecting through-hole, and a sealing gasket is added between the front end surface of the end plate and the end surface of the connection of the pump body to achieve sealing;

[0003] However, during the installation process, since it is necessary to seal and tightly connect the pump body and the end cover of the motor, it is necessary to ensure the flatness of the end faces pressed against each other. Since the contact area between the two is large and the flatness is limited, after it is clamped and installed by a density pad, the unevenness of the sealing pad is still prone to leakage after a certain period of use, affecting its use. Therefore, the sealing of the end cover of some existing motors is achieved by machining an annular groove on the outer wall of its raised part, and nesting the sealing ring in the annular groove, which forms a double seal with the sealing gasket to improve the sealing effect. However, in the existing annular groove processing, the end cover is generally clamped on a lathe and processed by a turning tool. However, due to the obstruction of the radially extending edge formed in the middle part of the outer wall of the end cover, the cutting tool of the lathe cannot approach the outer wall of the raised part for cutting.

[0054] When this embodiment is in use, the end plate 100 to be processed is first placed in the middle mounting recessed hole 13, and the middle clamping device 20 is in the middle through hole of the end cover 100. Then, the push rod of the upper pressing positioning oil cylinder 31 is pushed to make the lifting plate 32 descend, so that the conical portion of the bottom of the positioning column 33 is inserted into the middle clamping device 20, and the outer wall of the conical portion is against the upper inner wall of the clamping block 21. All the clamping blocks 21 are stretched outward so that the outer wall surface of the thickened outer wall plate 211 is pressed against the inner wall of the middle through hole of the end cover 100, thereby clamping and fixing the end cover 100 and aligning it.

[0056] Then, by loosening the corresponding locking nut and rotating the vertical adjustment stud, the height position of the cutting tool 71 can be changed so that it faces the position to be processed on the upper outer wall of the end cover 100, and then, the locking nut is tightened. Then, by rotating the reduction motor 11, the end cover 100 is rotated, pushing the push rod of the oil cylinder 65, so that the end of the cutting tool 71 contacts the upper outer wall of the end cover 100 for cutting processing. The pushing speed of the push rod of the pushing cylinder 65 of this embodiment is slow to ensure normal processing, and the moving distance of the cutting tool 71 can be changed before processing by loosening the locking nut 74 threaded on the screw part of the lateral adjustment bolt 73 and rotating the lateral adjustment bolt 73 to change the left and right position of the cutting tool 71 to ensure that when the push rod of the pushing cylinder 65 is pushed to the maximum position, the end of the cutting tool 71 reaches the inner wall of the annular groove processed on the outer wall of the end cover 100, which meets the design requirements.

At this time, downward tilt processing can be performed. When the push rod of the electric push rod 69 is pushed, it can move the moving block 691 to the left, and its bottom surface cooperates with and leans against the right side wall of the guide block 631. As the moving block 691 moves to the left, the cutting tool 71 can be horizontal, and horizontal processing and cutting can be performed.

[0058] When the cutting tool 71 needs to be tilted leftward and upward, the push rod of the electric push rod 69 can be continued to push, so that the moving block 691 moves leftward and the guide block 631 tilts downward, so that the cutting tool 71 tilts leftward and upward to meet the adjustment needs.

[0059] When this embodiment is in use, part of the coolant and chips will be between the inner limit sleeve 14 and the outer limit sleeve 15, and will be filtered through the filter mesh 52 of the filter connecting sleeve 50. The coolant will flow out from the lower discharge connector 40. The coolant can be connected to a drain pipe at the lower discharge connector 40, and the bottom of the drain pipe will extend into a liquid receiving box placed around it below for collection (the drain pipe and other components are omitted in the drawings).

[0060] When a lot of debris accumulates in the filter connecting sleeve 50 , it can be removed from the corresponding stepped through hole 61 and dumped out, which is very convenient.

[0061] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and is susceptible to numerous variations.
