Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] In addition, in the application, the terms "first", "second" and other similar words are not intended to imply any order, quantity and importance, but are merely used to distinguish different elements. The terms "upper", "lower", "left", "right" and other similar words are merely positional relationships in the drawings.

[0025] like Figure 1 As shown, the embodiment of the present application provides a bearing cover bevel milling device, comprising: a rotary 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 assembly 16. The rotary plate 1 is installed on one side of the translation plate 11, and the rotary plate 1 can rotate vertically; the translation plate 11 is installed on the top of the turntable 12, and the translation plate 11 can move linearly on the horizontal plane; the turntable 12 is used to drive the translation plate 11 to rotate horizontally; there are two first clamping plates 2, and they are symmetrically arranged on both sides of the rotary plate 1; a number of guide rods 3 are fixedly installed on the rotary plate 1, and the guide rods 3 pass through the first clamping plate 2 and limit the first clamping plate 2 so that the first clamping plate 2 can rotate horizontally. A clamping plate 2 can only move along the guide rod 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 in a straight line. 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 in the positioning plate 8, and the positioning rods 7 pass through the positioning plate 8 and are fixedly connected to the push plate 5. An elastic member 6 is sleeved on the positioning rod 7, and the elastic member 6 is located between the push plate 5 and the positioning plate 8; the milling assembly 16 is arranged above the rotating plate 1, and the workpiece can be milled by the milling assembly 16 when the rotating plate 1 rotates, the translation plate 11 moves, and the turntable 12 rotates. With such an arrangement, when in use, the user pushes the push plate 5 to the right, so that the push plate 5 moves 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 against the rotating plate 1. After releasing the push plate 5, under the action of the elastic member 6, the push plate 5 moves toward the baffle 4, thereby clamping the left and right surfaces of the bearing cover through the baffle 4 and the push plate 5; then, the front and rear surfaces of the bearing cover are clamped by two symmetrical first clamping plates 2.

[0026] In the process of clamping the bearing cover by the two first clamping plates 2, the two first clamping plates 2 are always symmetrical to the central plane of the rotating plate 1, so that the bearing cover can be kept in the central position of the rotating plate 1. In this way, the bearing cover can be positioned in the process of clamping the bearing cover, and then during milling, positioning compensation can be performed according to the size of the bearing cover without the need for re-calibration of the tool.

[0027] like Figure 1 As shown, in one 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, so that the rotating plate 1 can be driven to rotate by the first telescopic rod 15.

[0028] like Figure 1 As shown, in one embodiment of the present application, a plurality of equally spaced circumferentially distributed positioning blocks 13 are fixedly mounted on the base of a turntable 12. A linearly movable telescopic block 14 is mounted 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 cooperating with the telescopic block 14 and the positioning block 13.

[0029] In one embodiment of the present application, a bearing cap bevel milling device further includes: a synchronous movement mechanism, wherein the synchronous movement mechanism is used to drive the two first clamping plates 2 to move synchronously and equidistantly.

[0030] like Figure 2 As shown, in one 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 the second telescopic rod 17 can move linearly; two push blocks 18 are fixedly installed on the second telescopic rod 17, one of the push blocks 18 is installed with two first connecting rods 19, and the other push block 18 is installed with two second connecting rods 20. The two first connecting rods 19 and the two second connecting rods 20 are symmetrically arranged along the axial vertical center 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 splint 2, and one end of the second connecting rod 20 is rotatably connected to the first splint 2.

[0031] With such arrangement, when the second telescopic rod 17 moves linearly, it can drive the two first connecting rods 19 and the two second connecting rods 20 to move synchronously, thereby driving the two first clamping plates 2 to move synchronously and equidistantly.

[0032] In one embodiment of the present application, a bearing cap bevel milling device further includes: an angle limiting mechanism 10 , wherein the angle limiting mechanism 10 is used to limit the rotation angle of the rotary plate 1 .

[0033] like Figure 3 As shown, in one embodiment of the present application, the angle limiting mechanism 10 includes: a limiting block 101, an arcuate inner tooth block 102, a first gear 103, a second gear 104, a third gear 105, a worm wheel 106, and a worm 107. The limiting block 101 is rotatably mounted on the rotating plate 1, and an arcuate inner tooth block 102 is provided on one side of the limiting block 101. The arcuate inner tooth block 102 is meshed with the first gear 103, the first gear 103 is coaxially connected to the second gear 104, the second gear 104 is meshed with the third gear 105, the second gear 104 and the third gear 105 are bevel gears, the third gear 105 is coaxially connected to the worm wheel 106, and the worm wheel 106 is meshed with the worm 107.

[0034] With such an arrangement, the limit block 101 can be driven to rotate by rotating the worm 107 , and when the worm 107 is stationary, the angular position of the limit block 101 is locked.

[0035] When the limit block 101 is in the initial position, after the rotary plate 1 rotates 90°, the side surface of the limit block 101 will be in contact with the translation plate 11. Therefore, after the limit block 101 rotates to a specific angle a, the maximum rotation angle of the rotary plate 1 is (90-a)°; in this way, the maximum rotation angle of the rotary plate 1 can be limited by the angle limiting mechanism 10.

[0036] like Figure 4 As shown, in one embodiment of the present application, a bearing cap bevel milling device further includes a displacement sensor 21 for measuring the travel distance of the push plate 5. Thus, after the push plate 5 and the baffle 4 clamp the bearing cap, the travel distance of the push plate 5 can be used to determine the clamping position of the bearing cap. During milling, position compensation can be performed based on the travel distance of the push plate 5.

[0037] like Figure 4 As shown, in one embodiment of the present application, a bearing cap bevel milling device further includes an extension mechanism 22 slidably mounted on the first clamping plate 2, with each extension mechanism 22 corresponding to each first clamping plate 2. The extension mechanism 22 is configured to extend the clamping distance of the first clamping plate 2. When the distance between the front and rear sides of the bearing cap is less than the rated minimum distance between the two first clamping plates 2, the extension mechanism 22 can be moved to a clamping position, thereby clamping the bearing cap using the two extension mechanisms 22.

[0038] like Figure 5As shown, in one embodiment of the present application, the extension mechanism 22 includes: a slider 221, a positioning protrusion 222, and an abutment surface 223. The first splint 2 is provided with a slide rail 23, one end of the slider 221 is inserted into the slide rail 23, and the other end of the slider 221 is provided with an abutment surface 223, and the slider 221 is provided with a positioning protrusion 222. The positioning protrusion 222 is in contact with the first splint 2 to limit the insertion depth of the slider 221.

[0039] In one 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, and the slider 221 is provided with the first supporting surface 225. When the rotating block 224 rotates to the maximum angle position, the second supporting surface 226 abuts against the first supporting surface 225. Moreover, when the second supporting surface 226 abuts against the first supporting surface 225, the 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 further extended by the rotating block 224. When the bearing cap is clamped by the rotating block 224, the 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, thereby preventing the rotating block 224 from rotating during the clamping process.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
