[0028] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in combination with the drawings. In the following description, a lot of specific details are set forth in order to fully understand the utility model. But the utility model can be implemented in many other ways different from the description, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the following disclosed specific embodiments.
[0029] Refer to Figure 1The structure diagram of a vertical grinder quick alignment device is shown in the figure, which comprises a magnetic disc 100, a plurality of fulcrums 200 and two alignment assemblies 300; the magnetic disc 100 is provided with a plurality of sliding grooves 110; the plurality of fulcrums 200 are correspondingly arranged in the sliding grooves 110; the two alignment assemblies 300 are arranged on one side of the fulcrums 200, and each alignment assembly 300 comprises a support 310 detachably fixed in the sliding groove 110 and a connecting rod 320 mounted on the support 310; the support 310 is provided with a sliding through hole 311; one end of the connecting rod 320 is provided with a ball head top block 321; the outer diameter of the connecting rod 320 is provided with external threads; the connecting rod 320 passes through the sliding through hole 311; the first nut 330 and the second nut 340 are respectively screwed on the two sides of the sliding through hole 311 of the connecting rod 320 to lock the relative position of the connecting rod 320 and the sliding through hole 311.
[0030] When a new product is processed, after the product is changed to life, the first bearing ring 10 of the product is placed flat on the fulcrum 200, and the magnetic table stand is used for alignment. After the alignment is completed, the first bearing ring 10 is used as a reference to install the two alignment assemblies 300 on the sliding grooves 110 of the magnetic disc 100. After the ball head top block 321 of the connecting rod 320 is in contact with the surface of the bearing ring 10, the first nut 330 and the second nut 340 on both sides of the sliding through hole 311 are adjusted to clamp the support 310 from both sides and fix the alignment assembly 300. The positions of the two alignment assemblies 300 installed on the sliding grooves are separated by a certain angle.
[0031] From the processing of the second bearing ring 10, only the bearing ring 10 is placed flat on the fulcrum 200, and the bearing ring 10 is pushed by hand to make the bearing ring 10 in contact with the ball head top block 321 of the two alignment assemblies 300 to determine that the bearing ring 10 is aligned and qualified for processing the product.
[0032] During the use of the above-mentioned vertical grinder quick alignment device, the first bearing ring 10 alignment steps are as follows: install the magnetic table stand on the equipment, rotate the machine tool, knock the ring with a copper hammer to check the instrument change, stop the machine tool, and remove the magnetic table stand from the equipment. After the first bearing ring 10 is aligned, the alignment assembly 300 is fixed, and other bearing rings 10 only need to be pushed by hand to contact the ball head top block 321 to determine that the bearing ring 10 is aligned and qualified, reducing the number of times of knocking the bearing ring and the number of steps, and further improving the processing efficiency. In addition, when the above-mentioned vertical grinder quick alignment device is used for alignment, the magnetic disc 100 is in a static state, which reduces the safety hazard. The installation position of the alignment assembly 300 is the sliding groove 110 of the magnetic disc 100, and the bearing ring 10 rotates during processing, which avoids the phenomenon that the surface of the bearing ring 10 is scratched when the bearing ring 10 rotates and the alignment assembly 300 does not rotate.
[0033] Referring to Figure 6 In an embodiment, when the outer surface of the bearing ring 10 is aligned, the alignment assembly 300 is arranged on the side of the fulcrum 200 away from the center of the magnetic disc 100, and the ball head top block 321 is in contact with the outer surface of the bearing ring 10.
[0034] In an embodiment, the support 310 is L-shaped. It should be noted that the support 310 is arranged in an L shape, and the L shape has a first side and a second side perpendicular to each other, wherein the first side is provided with a bolt hole 312 perpendicular to the magnetic disc 100, and the second side is provided with a sliding through hole 311 for penetrating the connecting rod 320.
[0035] In an embodiment, the support 310 is provided with a bolt hole 312 in a direction perpendicular to the magnetic disc 100.
[0036] In an embodiment, the included angle between the two alignment assemblies 300 is 120°. In this way, the two alignment assemblies 300 are installed at an angle of 120°, so that the contact position of the bearing ring 10 and the ball head top block 321 is more uniform.
[0037] In another embodiment, the included angle between the two alignment assemblies 300 is 90°.
[0038] Referring to Figure 5 In an embodiment, when the inner surface of the bearing ring 10 is aligned, the alignment assembly 300 is arranged on the side of the fulcrum 200 close to the center of the magnetic disc 100, and the ball head top block 321 is in contact with the inner surface of the bearing ring 10.
[0039] The above-mentioned vertical grinding machine quick alignment device can adjust the installation direction of the alignment assembly 300 according to the alignment position of the bearing ring 10, and after adjusting the direction and position, the bolt hole 312 provided on the support 310 is fixed by cooperating with the bolt. Subsequently, only the relative position of the connecting rod 320 and the support 310 needs to be adjusted. When alignment is not required, the entire alignment assembly 300 can be removed from the sliding groove 110 to facilitate other operations. The tool disassembly method is simple.
[0040] In an embodiment, the connecting rod 320 can move in the sliding through hole 311 towards or away from the magnetic disc 100. At the same time, since the contact height of the ball head top block 321 of different products is different, the connecting rod 320 can move up and down, so that one set of tool can be used for alignment of various products, improving the flexibility of the device and widening the application range.
