[0002] Tooling, or process equipment, is the general term for various tools used in the manufacturing process, including tools / fixtures / molds / gauges / gauges / accessories / fitters / station tools, etc. Tooling is a general abbreviation for it. Processing tooling is also used in the manufacturing process of emery rollers. Processing tooling is used to fix the emery roller blank to ensure that the emery roller blank does not move during the processing.

[0003] The existing sand roller processing tooling is usually one-piece, and the larger sand roller processing tooling is usually placed vertically. Before processing, the processing tooling needs to be fixed on the machine tool, and then the sand roller lifting sleeve is set on the outside of the sand roller. During installation, the sand roller is hoisted at a high height, which is difficult for operators to observe and is easy to damage the sand roller blank. In addition, the one-piece processing tooling is large in size and inconvenient to hoist. Utility Model Content

[0007] The connecting plate is provided with a first countersunk threaded hole and a thread hole, the base is provided with a second countersunk threaded hole, a bolt hole and a waist-shaped hole, the second countersunk threaded hole is provided with a first fixing bolt for fixing the base to an external machine tool, the thread hole and the waist-shaped hole are provided with a second fixing bolt for fixing the spindle and the connecting plate to the base, and the first countersunk threaded hole and the bolt hole are provided with a third fixing bolt for fixing the spindle, the connecting plate and the base to an external machine tool.

[0008] Furthermore, four first countersunk threaded holes and four threaded holes are evenly and radially opened on the connecting disk, and the first countersunk threaded holes and the threaded holes are staggered and their axes are located on the same circumference.

[0009] Furthermore, four second countersunk threaded holes are evenly opened radially on the base, four bolt holes are evenly opened radially on the base, the four bolt holes are all located outside the four second countersunk threaded holes, and four waist-shaped holes are evenly opened radially on the base, the bolt holes and waist-shaped holes are staggered and the axes are located on the same circle.

[0010] Furthermore, the connecting shaft is in a truncated cone shape, and a locking groove for cooperating with an external machine tool is provided at the connection between the connecting shaft and the base.

[0011] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0012] The utility model divides the integrated processing tooling into four components: a main shaft, a connecting plate, a base and a connecting shaft. The main shaft and the connecting plate are fixedly connected, and the base and the connecting shaft are fixedly connected. The installation and disassembly are convenient. When processing the sand roller, the main shaft and the connecting plate are first placed on the ground, and then the sand roller blank is hoisted onto the main shaft, and the sand roller blank is fixed to the main shaft through an external locking nut, and then the main shaft and the connecting plate are hoisted onto the base installed on the machine tool. The height of the sand roller blank when hoisting can be reduced, which is convenient for staff to observe and reduces the probability of damage to the sand roller blank.
