Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub blank processing and manufacturing, in particular to a wheel hub blank concentricity detection tool. Background Art

[0002] During the production process, the wheel hub blank may be defective due to poor mold installation or the accuracy and wear of the mold itself. The most common one is that the concentricity is too large. Too much concentricity will cause the lathe jaws to be stuck during the processing of the blank, resulting in unprocessed black skin inside the processed wheel and poor balance of the processed finished product. Therefore, the concentricity of the wheel hub blank needs to be tested before processing. The quality of concentricity directly affects the quality of subsequent processing. There are many ways to test concentricity. There are two commonly used methods in the prior art. One is to fix the intermediate positioning three-claw chuck and then rotate it for detection, and the other is to It is a three-finger fixed detection. The first type is generally used for positioning the center hole of the wheel hub after processing is completed. The other type is used for positioning the wheel hub blank. The disadvantages of these two detection methods are that the size of the fingers is relatively small. Every time a specification of wheel hub blank is replaced, the corresponding finger claw tooling needs to be replaced for installation and debugging to ensure the concentricity of the tooling to ensure the correctness of the detection result, so it takes a long time; the center rotating bearing arrangement is suitable for a small range of wheel hub blanks. When detecting large-size wheel hub blanks, the concentricity detection result is very poor. Therefore, the technology in this field proposes a wheel hub blank concentricity detection tooling to solve the above problems. Utility Model Content

[0003] In order to make up for the above shortcomings, the utility model provides a wheel hub blank concentricity detection tooling, aiming to improve the problem that the concentricity detection method of the wheel hub blank in the prior art is difficult to adapt to the different sizes of the wheel hub blank during production, resulting in the detected concentricity of the wheel hub blank being not accurate enough.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wheel hub blank concentricity detection tool, including a mounting cabinet, the top of which is fixedly connected to a detection platform body, the outside of which is fixedly connected to a positioning plate, the bottom of which is threadedly connected to a stop nut, the interior of which is provided with two mounting grooves, and the interior of which is rotatably connected to a bearing.

[0005] Furthermore, the top of the positioning plate is detachably connected to a connecting plate, and the top of the connecting plate is fixedly connected to a transition plate.

[0006] Furthermore, the interior of the positioning disk is rotatably connected with a central axis, and is located at the center of the connection disk.

[0007] Furthermore, the top of the transition plate is slidably connected with two finger claws.

[0008] Furthermore, two second fingers are slidably connected to the outer side of the transition plate and are located at the edge of the transition plate.

[0009] Furthermore, a hub blank is arranged on the top of the transition plate.

[0010] The utility model has the following beneficial effects:

[0011] 1. In the utility model, through the mutual cooperation of the transition plate, the first finger claw, the second finger claw, the stop nut, the positioning plate and other structures, the finger claws matching the wheel hub blank are used for clamping, and the wheel hub blanks of different specifications and sizes are clamped through different steps.

[0012] 2. In the utility model, through the mutual cooperation of the positioning plate, the connecting plate, the center shaft, the bearing and other structures, the concentricity of the center rotation can be realized by the center shaft around a pair of bearings. The bearings are installed in the positioning plate, and the distance between the two bearings is increased to a suitable length to ensure that the wheel hub blanks of different specifications to be tested can be successfully tested.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-Figure 3 The utility model provides an embodiment: a wheel hub blank concentricity detection tool, including an installation cabinet 11, the top of the installation cabinet 11 is fixedly connected with a detection platform body 1, the outside of the detection platform body 1 is fixedly connected with a positioning plate 7, the bottom of the positioning plate 7 is threadedly connected with a stop nut 6, the interior of the positioning plate 7 is provided with two installation grooves 12, the interior of the installation groove 12 is rotatably connected with a bearing 10, first of all, it is necessary to ensure that the concentricity of the detection tool is correct, and the concentricity of the tool is reliable after multiple clamping, the tool for clamping the wheel hub blank 5 must be accurate and reliable, and the wheel hub blank 5 is clamped by using the finger claw 1 3 and the finger claw 2 4 matching the wheel hub blank 5, and different specifications and sizes of wheel hub blanks 5 are clamped through different steps, and the steps of different specifications are integrated, so that one-time installation and adjustment can be achieved to adapt to all specifications of wheel hub blanks 5.

[0026] Reference Figure 4-Figure 6 The top of the positioning disk 7 is detachably connected to the connecting disk 8, and the top of the connecting disk 8 is fixedly connected to the transition disk 2. The interior of the positioning disk 7 is rotatably connected to the center shaft 9, and is located at the center of the connecting disk 8. The vertical surface of the step ensures that the rotation center of the hub blank 5 is on the center shaft 9 during rotation. The tooling has multiple sets of steps, which can adapt to hub blanks 5 of different specifications. The so-called center rotation tooling is composed of a connecting disk 8, a positioning disk 7, a center shaft 9, a bearing 10 and a stop nut 6. The stop nut 6 is used to prevent the rotating tooling from loosening. By designing the position of the two sets of rotating pairs of the center shaft 9, it is ensured that multiple sets of hub blanks 5 of different specifications can be used for concentricity detection of this equipment to detect the concentricity of the hub blank 5.

[0027] Reference Figure 7-Figure 9 The top of the transition plate 2 is slidably connected to two finger claws 1 3, and the outer side of the transition plate 2 is slidably connected to two finger claws 2 4, and is located at the edge of the transition plate 2. The two sets of finger claws 1 3 cooperate with finger claws 2 4 to clamp the hub blank 5. The top of the transition plate 2 is provided with a hub blank 5. The finger claws 1 3 and finger claws 2 4 are steps formed by one-time wire cutting of the machine tool. The angle of the step is consistent with the edge angle of the blank, which ensures that the blank can be perfectly fitted into the clamp after being placed in the clamp to avoid concentricity errors caused by inadequate clamping of the fixture. The one-time molding process will also ensure the flatness of the three planes of the step, which can ensure the flatness of the hub blank 5 and the tooling.

[0028] Working principle: The positioning plate 7 is installed on the testing table body 1, and the bearing 10 is installed inside the positioning plate 7 to realize the rotation of the central axis 9. The central axis 9 is rigidly connected to the connecting plate 8. One end of the transition plate 2 is installed on the connecting plate 8 of the rotating tooling, and the other end is equipped with two finger claws 1 3 and finger claw 2 4. The wheel hub blanks 5 of different sizes to be tested are placed between the finger claws 1 3 and the finger claws 2 4, and the concentricity of the blanks is accurately tested by a dial indicator.
