Description

Technical Field

[0001] The invention relates to the technical field of motor housing end covers, and in particular to a milling device for a motor housing end cover and a milling process thereof. Background Art

[0002] The motor housing end cover plays an important role in the motor. The end cover is used to close the non-driving end of the motor, protect the internal electrical components such as windings, insulating materials and bearings, and prevent dust, moisture and other external impurities from entering. It is usually fixed to the stator of the motor by bolts to provide structural support and stability for the motor. Bearings are usually installed inside the end cover to support the rotor of the motor and ensure the correct position and rotation accuracy of the rotor. The bearing is installed in the bearing chamber on the end cover, and the bearing chamber needs to be milled to ensure the accurate installation of the bearing. The bearing chamber needs to be positioned and fixed by the end cover during milling to ensure the stability of the end cover during the milling process. The existing milling equipment has a relatively complicated operation of the positioning mechanism of the end cover, and cannot achieve rapid positioning and fixing of the end cover. In addition, the existing milling equipment cannot limit the waste chips generated during the milling process, resulting in waste chips splashing everywhere, which is not conducive to the cleaning and collection of waste chips, making the work intensity of the staff greater.

[0014] A motor housing end cover milling process comprises the following steps:

[0015] Step 1: Placement of the end cap: Place the end cap on the milling platform;

[0016] Step 2: Positioning and adjusting the end cover: Start the electric telescopic rod to drive the milling platform to move, and then drive the driving ring to move downward. As the driving ring moves downward, it will drive the adjustment push rod to move and then push the end cover to achieve position adjustment;

[0017] Step 3: Fixing of the end cap: As the milling platform moves, the U-shaped slats will move downward to form negative pressure to achieve adsorption and fixation of the end cap, while the limiting sleeve is pressed on the end cap to achieve double fixation;

[0018] Step 4: Milling of the end cover: The milling cutter moves down into the limiting sleeve to mill the bearing chamber.

[0019] Compared with the prior art, the invention has the following advantages:

[0020] 1. A milling bearing platform is provided on the milling equipment body. When milling the bearing chamber on the end cover, the end cover is placed on the milling bearing platform, and the electric telescopic rod is started to drive the milling bearing platform to move inside the milling equipment body. During the movement, the driving ring moves downward and then drives the adjusting push rod to move to adjust the position of the end cover, so that its position is accurately positioned, and there is no need to manually adjust the position of the end cover.

[0021] 2. After the position of the end cover is adjusted, as the milling support platform continues to move, the U-shaped slat will be driven downward by the action of the movable sleeve block. As the U-shaped slat moves downward, the matching plug plate will be driven downward, so that negative pressure is formed in the matching cavity to adsorb and fix the end cover from the bottom, thereby realizing the first layer of fixation of the end cover. At the same time, it will also drive the limiting sleeve to move downward and press on the end cover, thereby performing the second layer of fixation on the end cover from the top, thereby fully ensuring the stability of the end cover, preventing it from rotating during the milling process, and ensuring the smooth progress of the milling.

[0022] 3. In addition, the limiting sleeve is located directly above the bearing chamber, and the milling cutter mills the bearing chamber in the limiting sleeve. Under the action of the limiting sleeve, the waste chips on the outside of the end cover can be prevented from splashing randomly, and the U-shaped slats will also drive the pushing plate to move away from the placement groove when moving downward, so that the waste chips under the end cover can be concentrated between the two pushing plates. When the milling is completed, with the resetting of the pushing plate, most of the waste chips on the milling support table can be pushed into the collection box for collection, which greatly reduces the workload of the staff in cleaning and improves the efficiency of waste chip cleaning.

[0046] A motor housing end cover milling process comprises the following steps:

[0047] Step 1: Placement of the end cap: Place the end cap on the milling support platform 2;

[0048] Step 2: Positioning and adjusting the end cover: Start the electric telescopic rod 12 to drive the milling platform 2 to move, and then drive the driving ring 3 to move downward. As the driving ring 3 moves downward, it will drive the adjustment push rod 35 to move and then push the end cover to achieve position adjustment;

[0049] Step 3: Fixing the end cap: As the milling platform 2 moves, the U-shaped strip 4 moves downward to form a negative pressure to achieve adsorption and fixation of the end cap, and at the same time, the limiting sleeve 48 is pressed on the end cap to achieve double fixation;

[0050] Step 4: Milling of the end cover: The milling cutter moves downward into the limiting sleeve 48 to mill the bearing chamber.

[0051] When milling the bearing chamber on the end cover, the end cover is placed on the milling support platform 2. At this time, the inner top surface of the end cover is in close contact with the upper end surface of the support platform 27. Then the electric telescopic rod 12 is started to drive the milling support platform 2 to move into the interior of the milling equipment body 1. As the milling support platform 2 moves, the matching column 39 is pushed downward under the action of the inclined lower pressure strip 15, thereby driving the drive ring 3 to move downward. As the drive ring 3 moves downward, the connecting column 37 is driven to move toward the end cover under the action of the connecting drive frame 34, thereby causing the adjusting push rod 35 to move toward the end cover. In this way, the adjusting push rod 35 is pushed The end cover moves, and then the end cover is adjusted from all sides of the end cover to accurately position it. As the milling carrier 2 continues to move, the movable sleeve block 5 will contact the lateral carrier plate 13, and the movable sleeve block 5 will no longer move, so that the distance between the movable sleeve block 5 and the fixed end block 22 becomes smaller, so that under the action of the first matching rod 53, the U-shaped slat 4 will be pushed downward, and as the U-shaped slat 4 moves downward, the matching plug plate 44 will be driven downward, so that negative pressure can be formed in the matching cavity 271 to fix it from the inside of the end cover, and as the U-shaped slat 4 moves downward, the limiting sleeve 48 will be driven downward to press on the end cover to fix it. The clamping and fixing, that is, fixing the end cover from the upper and lower sides to ensure its stability during the milling process, can realize the rapid automatic positioning and fixing of the end cover, and the limiting sleeve 48 is located directly above the bearing chamber. When the bearing chamber is milled, the milling cutter enters the bearing chamber from the limiting sleeve 48 to mill the bearing chamber. The limiting sleeve 48 can prevent the waste chips on the outside of the end cover from splashing randomly. In addition, when the U-shaped slat 4 moves downward, the push plate 7 will be driven to move away from the placement groove 26 under the action of the second matching rod 6, so that the waste chips on the inner side of the end cover can be located between the two pushing plates 7 during the milling process, and the push plate 7 moves away from the placement groove 26. When moving, the arc contact surface 76 will contact the inner wall of the end cover, so that the movable matching plate 75 will be pushed to move under the restriction of the inner wall of the end cover so that the third spring 79 is in a compressed state, ensuring the smooth movement of the push plate 7. When the milling is completed, the push plate 7 is reset. During the reset process, most of the waste chips on the milling support platform 2 can be pushed into the collection box 8 for collection, which greatly reduces the workload of the staff in cleaning and improves the efficiency of cleaning. It is very convenient. When the collection box 8 needs to be taken out, it can be quickly taken out for cleaning by pushing the matching push rod 81 upward from the bottom of the milling support platform 2.
