As used in the description of the embodiments of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms of "a", "an" and "the" are intended to include plural forms.

[0033] As shown in the accompanying drawings, a specific embodiment of the present invention is a grinding device for automotive parts castings, comprising a machine platform 1; a clamping assembly, a driving assembly and a grinding assembly;

[0034] The clamping assembly is arranged on the machine platform 1, and the clamping assembly is used to clamp the automobile wheel hub 12;

[0035] The driving assembly is arranged on the machine platform 1, and the driving assembly includes a lateral displacement mechanism, a longitudinal displacement mechanism and a vertical displacement mechanism. The lateral displacement mechanism is arranged on the machine platform 1, the longitudinal displacement mechanism is arranged on the lateral displacement mechanism, and the vertical displacement mechanism is arranged on the longitudinal displacement mechanism;

[0036] The grinding assembly is mounted on the longitudinal displacement mechanism, and the grinding assembly is positionally adjusted by the driving mechanism so as to grind the automobile wheel hub 12 on the clamping assembly.

[0037] In this embodiment, specifically, the lateral displacement mechanism includes a motor 8, a guide rail 3, a movable frame 6 and a screw rod. The guide rail 3 is installed on the machine 1, and the movable frame 6 is movably installed on the guide rail 3. The movable frame 6 is threadedly connected to the screw rod. The motor 8 is connected to the screw rod in a transmission manner. The movable frame is driven to move on the guide rail by the rotation of the motor to achieve the lateral displacement of the grinding assembly. Further, the longitudinal displacement mechanism includes a cylinder 5 and a movable plate 4. The upper end of the movable frame 6 is provided with a slide groove that cooperates with the movable plate 4. The cylinder 5 is arranged at the upper end of the movable frame 6. The cylinder 5 is used to drive the movable plate 4 to slide in the slide groove. The movable plate is driven to move in the slide groove by the cylinder to achieve the longitudinal displacement of the grinding assembly. Further, the vertical displacement mechanism includes a hydraulic cylinder 7. The hydraulic cylinder 7 is installed on the movable plate 4. The grinding assembly is arranged at the lower end of the hydraulic cylinder 7. The grinding assembly is driven to move vertically by the hydraulic cylinder.

[0038] As another embodiment of the present invention, the clamping assembly includes a clamping seat 2 and a plurality of clamping assemblies, and the plurality of clamping assemblies are distributed in annular intervals on the clamping seat 2. Specifically, the clamping assembly includes an electric telescopic rod 11 and a clamping block 9, the electric telescopic rod 11 is installed at the lower end of the clamping seat 2, the clamping seat 2 is provided with a slot 10 that cooperates with the clamping block 9, the clamping block 9 is provided with a limiting groove 24 that cooperates with the slot 10, and the electric telescopic rod 11 is used to drive the clamping block 9 to move in the limiting groove 24 to clamp the automobile wheel hub 12.

[0039] The clamping block 9 is provided with a clamping plate 13 and a spring 15, the clamping block 9 is provided with a movable groove 14 matched with the clamping plate 13, the clamping plate 13 is provided with a boss, one end of the spring 15 is connected to the boss, and the other end is connected to the bottom of the movable groove 14. By providing the clamping plate and the spring 1, the clamping assembly can adapt to the clamping of automobile wheels of various specifications and diameters, so that the versatility of the device is greatly improved.

[0040] Those skilled in the art will know that due to the large differences in wheel hub diameters, when clamping some wheel hubs with larger diameters, since the travel of the electric telescopic rod is fixed, the spring 1 will be compressed more and may exceed the yield limit of the spring 1. Therefore, in this embodiment, an adjustment component is also provided in the clamping block 9, and the adjustment component is used to adjust the positioning position of the spring 15. Specifically, the adjustment component includes an adjustment ring 16 and a limiting mechanism, one end of the spring 15 is fixedly connected to one end of the adjustment ring 16, the bottom of the movable groove 14 is provided with a mounting hole 17, the adjustment ring 16 is installed in the mounting hole 17, and the limiting mechanism is provided on the hole wall of the mounting hole 17 to position the adjustment ring 16.

[0041] Furthermore, the limiting mechanism includes a rotating rod 21, a spring 22, a clamping block 19 and a top block 23. A receiving groove 20 is provided on the hole wall of the mounting hole 17. The rotating rod 21 can be rotatably installed in the receiving groove 20. The clamping block 19 and the top block 23 are respectively installed at both ends of the rotating rod 21. One end of the spring 22 is connected to the top of the top block 23, and the other end is fixedly connected to the bottom of the receiving groove 20. One end of the top block 23 away from the spring 22 abuts against the clamping plate 13. A groove section 18 is provided on the clamping plate 13. One end of the clamping block 19 abuts against one end of the adjusting ring 16 away from the spring 15.

[0042] In the above scheme, when clamping some automobile wheels with smaller diameters, the states of the clamping plate and the limiting mechanism are as follows: Figure 5 As shown, under the action of spring two, one end of the clamping block abuts against one end of the adjusting ring to limit the adjusting ring. When clamping some automobile wheel hubs with larger diameters, the travel of the clamping block becomes larger until the top block enters the groove section under the action of spring two. After the top block enters the groove section, the rotating rod rotates to drive the clamping block to rotate and disengage from the adjusting ring. The limiting of the adjusting ring is released, and the clamping plate, spring one and the adjusting ring as a whole move in the direction in which the spring one is compressed, so that the device can clamp automobile wheel hubs with larger diameters without damaging the spring one, thereby further improving the versatility of the device.

[0043] The above description is only for the best embodiment of the present invention, but it should not be understood as limiting the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the scope of protection of the independent claims of the present invention are within the scope of protection of the present invention.
