Detailed Description of the Embodiment

[0017] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0018] In addition, in the application, the terms "first", "second" and other similar terms do not intend to imply any order, quantity and importance, but are only used to distinguish different elements. The terms "upper", "lower", "left", "right" and other similar terms are only the positional relationships in the drawings.

[0019] As Figure 1 shown, an inclined plane milling device for a bearing cover provided by an embodiment of the present application includes: a rotating plate 1, a first clamping plate 2, a guide rod 3, a baffle 4, a push plate 5, a translation plate 11, a turntable 12, and a milling component 16. The rotating plate 1 is installed on one side of the translation plate 11 and can rotate vertically; the translation plate 11 is installed on the top of the turntable 12 and can move linearly on a horizontal plane; the turntable 12 is used to drive the translation plate 11 to rotate horizontally; two first clamping plates 2 are provided and symmetrically arranged on both sides of the rotating plate 1; a plurality of guide rods 3 are fixedly installed on the rotating plate 1, and the guide rods 3 penetrate through the first clamping plate 2 to limit the first clamping plate 2, so that the first clamping plate 2 can only move along the guide rods 3; a baffle 4 is provided on the rotating plate 1, and the baffle 4 is fixedly connected to the rotating plate 1. A push plate 5 is provided on one side of the baffle 4, and the push plate 5 can move linearly. A positioning plate 8 is provided on one side of the push plate 5, and the positioning plate 8 is fixedly connected to the rotating plate 1. A plurality of positioning rods 7 are inserted into the positioning plate 8, and the positioning rods 7 penetrate through the positioning plate 8 and are fixedly connected to the push plate 5. An elastic member 6 is sleeved on the positioning rods 7, and the elastic member 6 is located between the push plate 5 and the positioning plate 8; the milling component 16 is arranged above the rotating plate 1, and the workpiece can be milled by the milling component 16 when the rotating plate 1 rotates, the translation plate 11 moves, and the turntable 12 rotates. With such a setting, when in use, the user pushes the push plate 5 to the right to make the push plate 5 away from the baffle 4, places the bearing cover between the baffle 4 and the push plate 5, and the bottom of the bearing cover fits with the rotating plate 1. After releasing the push plate 5, under the action of the elastic member 6, the push plate 5 moves towards the baffle 4, so as to clamp the left and right two faces of the bearing cover through the baffle 4 and the push plate 5; subsequently, the front and rear two faces of the bearing cover are clamped by two symmetric first clamping plates 2.

[0020] During the process of the two first clamping plates 2 clamping the bearing cover, the two first clamping plates 2 are always symmetrical about the central plane of the rotating plate 1. In this way, the bearing cover can be kept at the central position of the rotating plate 1, so that the bearing cover can be positioned during the clamping process. Furthermore, during milling, positioning compensation can be performed according to the size of the bearing cover, and there is no need to re-align the tool.

[0021] As Figure 1 shown, in an embodiment of the present application, a column 9 is installed on the rotating plate 1, and a first telescopic rod 15 is installed on the translation plate 11. One end of the first telescopic rod 15 is rotatably connected to the column 9. In this way, the rotating plate 1 can be driven to rotate by the first telescopic rod 15.

[0022] As Figure 1 shown, in an embodiment of the present application, a plurality of positioning blocks 13 evenly distributed in a circumferential manner are fixedly installed on the base of the turntable 12, and a telescopic block 14 that can move linearly is installed on the turntable 12. When the turntable 12 rotates, the telescopic block 14 retracts into the turntable 12. After the turntable 12 rotates to a specified angular position, the telescopic block 14 extends out of the turntable 12. In this way, the turntable 12 can be rotated to a specific angular position by the cooperation of the telescopic block 14 and the positioning blocks 13.

[0023] In an embodiment of the present application, a bearing cover bevel milling device further includes: a synchronous movement mechanism for driving the two first clamping plates 2 to move synchronously and equidistantly.

[0024] As Figure 2 shown, in an embodiment of the present application, the synchronous movement mechanism includes: a second telescopic rod 17, a push block 18, a first connecting rod 19, and a second connecting rod 20. The second telescopic rod 17 is installed on the rotating plate 1 and can move linearly; two push blocks 18 are fixedly installed on the second telescopic rod 17. Two first connecting rods 19 are installed on one of the push blocks 18, and two second connecting rods 20 are installed on the other push block 18. The two first connecting rods 19 and the two second connecting rods 20 are symmetrically arranged along the axial vertical central plane of the second telescopic rod 17, and on one side of the push block 18, the first connecting rod 19 is parallel to the second connecting rod 20. One end of the first connecting rod 19 is rotatably connected to the first clamping plate 2, and one end of the second connecting rod 20 is rotatably connected to the first clamping plate 2.

[0025] With such a setting, when the second telescopic rod 17 moves linearly, the two first connecting rods 19 and the two second connecting rods 20 can be driven to move synchronously, and further drive the two first clamping plates 2 to move synchronously and equidistantly.

[0026] In an embodiment of the present application, a bearing cover bevel milling device further includes: an angle limiting mechanism 10 for limiting the rotation angle of the rotating plate 1.

[0027] As Figure 3 shown, in an embodiment of the present application, the angle limiting mechanism 10 includes: a limiting block 101, an arc-shaped internal gear block 102, a first gear 103, a second gear 104, a third gear 105, a worm gear 106, and a worm 107. The limiting block 101 is rotatably mounted on the rotating plate 1. An arc-shaped internal gear block 102 is provided on one side of the limiting block 101. The arc-shaped internal gear block 102 is meshed and connected with the first gear 103. The first gear 103 is coaxially connected with the second gear 104. The second gear 104 is meshed and connected with the third gear 105. The second gear 104 and the third gear 105 are bevel gears. The third gear 105 is coaxially connected with the worm gear 106. The worm gear 106 is meshed and connected with the worm 107.

[0028] With such a setting, the limiting block 101 can be driven to rotate by rotating the worm 107, and when the worm 107 is stationary, the angular position of the limiting block 101 is locked.

[0029] When the limiting block 101 is in the initial position, after the rotating plate 1 rotates 90°, the side surface of the limiting block 101 will be in contact with the translation plate 11. Therefore, when the limiting block 101 rotates to a specific angle a, the maximum rotation angle of the rotating plate 1 is (90 - a)°; thus, the maximum rotation angle of the rotating plate 1 can be limited by the angle limiting mechanism 10.

[0030] As Figure 4 shown, in an embodiment of the present application, a bearing cover milling inclined plane device further includes: a displacement sensor 21, and the displacement sensor 21 is used to measure the moving distance of the push plate 5. In this way, after the push plate 5 and the baffle 4 clamp the bearing cover, the clamping position of the bearing cover can be judged by the moving distance of the push plate 5, and during milling, position compensation can be performed according to the moving distance of the push plate 5.

[0031] As Figure 4 shown, in an embodiment of the present application, a bearing cover milling inclined plane device further includes: an extension mechanism 22. The extension mechanism 22 is slidably mounted on the first clamping plate 2, and the extension mechanism 22 is provided in one-to-one correspondence with the first clamping plate 2; the extension mechanism 22 is used to extend the clamping distance of the first clamping plate 2. When the distance between the front and rear side surfaces of the bearing cover is less than the rated minimum distance between the two first clamping plates 2, the extension mechanism 22 can be moved to the clamping position to clamp the bearing cover by the two extension mechanisms 22.

[0032] As Figure 5As shown, in an embodiment of the present application, the extension mechanism 22 includes: a slider 221, a positioning protrusion 222, and an abutting surface 223. A slide rail 23 is provided on the first clamping plate 2. One end of the slider 221 is inserted into the slide rail 23. The other end of the slider 221 is provided with the abutting surface 223. And a positioning protrusion 222 is provided on the slider 221. The positioning protrusion 222 abuts against the first clamping plate 2 to limit the insertion depth of the slider 221.

[0033] In an embodiment of the present application, the extension mechanism 22 further includes: a rotating block 224, a first supporting surface 225, and a second supporting surface 226. The rotating block 224 is rotatably mounted on the slider 221. The rotating block 224 is provided with the second supporting surface 226. The first supporting surface 225 is provided on the slider 221. When the rotating block 224 rotates to the maximum angle position, the second supporting surface 226 abuts against the first supporting surface 225. And when the second supporting surface 226 abuts against the first supporting surface 225, the included angle between the rotating block 224 and the slider 221 is greater than 180°. In this way, the clamping surface of the first clamping plate 2 can be extended again through the rotating block 224. When clamping the bearing cover through the rotating block 224, the included angle between the rotating block 224 and the slider 221 is greater than 180°. At this time, the rotating block 224 is supported by the first supporting surface 225 and the second supporting surface 226, which can prevent the rotating block 224 from rotating during the clamping process.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
