Description

Technical Field

[0001] The utility model relates to the technical field of rotor assembly, in particular to a universal motor rotor height flatness detection device. Background Art

[0002] The incoming automotive motor rotors are stacked together piece by piece, not compacted, with gaps in the middle, and need to be compacted. After the product is pre-pressed, its height and plane need to be tested. In the past, they were mostly tested separately, with low testing efficiency. Products of different sizes have different heights and inner and outer diameters. Product height detection is mostly done with displacement sensors. If the workpiece is used as the benchmark, the heights of products of different sizes vary greatly, and it is difficult to contact the benchmark tooling for downward pressure testing. Since the products are stacked together piece by piece, the bottom sheet product is close to the tooling, and it is difficult to remove them together after the test is completed.

[0003] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a universal motor rotor height flatness detection device. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a universal motor rotor height and flatness detection device, which is cleverly designed and can adjust the positioning and detection reference according to products of different sizes, detect the product height and the product flatness at the same time, and float and lift the detected product for subsequent material retrieval.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a universal motor rotor height flatness detection device, which includes a tooling mechanism, an inductive sensor arranged at the side end of the tooling mechanism for identifying incoming materials, and a pressurized detection mechanism located above the tooling mechanism and docked with it. The tooling mechanism includes a positioning table, a reference block assembly, a positioning assembly and a floating assembly. A reference block assembly with adjustable height is installed in the middle of the positioning table to adapt to products of different heights. A slide groove is provided on the positioning table, and two positioning assemblies for positioning the product from the inner diameter are installed in the slide groove. A floating assembly for floatingly lifting the product for material retrieval is also installed on the positioning table.

[0006] Preferably, the reference block assembly includes a base plate mounted to the bottom of the positioning platform, a bolt threadedly connected to the base plate, and a reference block threadedly mounted on the bolt, and the height of the reference block is adjusted by rotating it.

[0007] Preferably, the positioning assembly includes a mounting block disposed in the slide groove and a positioning column fixed to the mounting block. After the position is adjusted, the mounting block is screwed to the positioning table by screws to be suitable for products of different sizes.

[0008] Preferably, the floating component includes an elastic block and an elastic column. The elastic block is mounted on the positioning table through the elastic column. Under the pressurized state, the elastic block is flush with the surface of the positioning table. After the detection is completed, the elastic column can lift the elastic block.

[0009] Preferably, the pressurized detection mechanism includes a detection bracket, a detection servo electric cylinder mounted on the top plate of the detection bracket, a detection lifting frame driven by the detection servo electric cylinder to move downward, a detection pressure head mounted on the detection lifting frame, and a displacement sensor. The displacement sensor is opposite to the reference block assembly. A plurality of contact displacement sensors are also mounted on the detection lifting frame and are distributed in a concentric array and pass through the detection pressure head. The multi-point contact displacement sensor detects the flatness of the product surface.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] The detection mechanism applies a certain pressure to detect the height of the product to be detected, and at the same time, the multi-point contact displacement sensor detects the flatness of the product surface;

[0012] The tooling mechanism is configured with a reference block assembly, which can adjust the reference height according to products of different heights, and has wide applicability;

[0013] The positioning component can adjust the installation position according to products of different inner diameters, and position the product from the inside of the product for subsequent pressurized detection;

[0014] After the detection is completed, the floating component can lift the product, and the bottom surface of the product is separated from the surface of the positioning table, which is convenient for taking the product. Description of the Drawings

[0024] The reference block assembly 12 includes a base plate 121 installed on the bottom of the positioning platform 11, a bolt 122 threadedly connected to the base plate 121, and a reference block 123 threadedly installed on the bolt 122. The height of the reference block 123 is adjusted by rotating the reference block 123. When working, the reference block assembly 123 is lower than the product and is fixed. For products of different sizes, the height of the reference block 123 is adjustable. If the positioning platform 11 is used as a reference, for relatively high products, it is difficult for the pressurized detection mechanism 3 to contact the reference bottom surface.

[0025] The floating component 14 includes an elastic block 141 and an elastic column 142. The elastic block 141 is mounted on the positioning table 11 through the elastic column 142. In the pressurized state, the elastic block 141 is flush with the surface of the positioning table 11. After the detection is completed, the elastic column 142 can lift the elastic block 141, and the product on the positioning table 11 is lifted, and the bottom surface of the product is separated from the surface of the positioning table 11, which is convenient for taking the product. Otherwise, the bottom surface of the product is closely attached to the positioning table 11 without gaps, and it is difficult to grasp the bottom product when taking the product.

[0026] The pressurized detection mechanism 3 includes a detection bracket 31, a detection servo cylinder 32 mounted on the top plate of the detection bracket 31, a detection lifting frame 33 driven by the detection servo cylinder 32 to move downward, a detection pressure head 34 mounted on the detection lifting frame 33, and a displacement sensor 35. The displacement sensor 35 faces the reference block assembly 12. A plurality of contact displacement sensors 36 that are concentrically arrayed and pass through the detection pressure head 34 are also mounted on the detection lifting frame 33. The multi-point contact displacement sensor 36 detects the flatness of the product surface. In the pressurized state, the flatness is judged by the numerical changes of multiple sensors. If the values are relatively close, the flatness is good. If the values differ greatly, the flatness of the product is poor.

[0027] The universal motor rotor height and flatness detection device of the present invention is ingeniously designed, can adjust the positioning and detection reference according to products of different sizes, detect the flatness of the product while detecting the height of the product, and lift the detected product floatingly for subsequent material taking.
