[0002] Due to the characteristics of the sand roller products, after the end face of the sand roller is processed by the end face machine, it is transferred to the external cylindrical machine tool to use the external cylindrical cutter to process the external cylindrical part, and the end face of the sand roller is processed by the grinding cutter. Finally, it is transferred to the grooving machine tool to use the grooving cutter to process the sand roller groove to complete the sand roller processing.

[0003] At the same time, because the processing of emery roller products requires multiple processes, multiple techniques, and multiple processing with multiple tools to realize product processing, the existing equipment for processing emery rollers cannot meet the requirements of one-time clamping and one-time processing of emery rollers, and they need to be transferred between different machine tools. Due to clamping deviation, the finished product groove and outer circle have eccentricity problems, making the product size unable to meet the high-precision requirements of the drawings.

[0026] See also Figure 1-4 A power assembly 8 is fixedly installed on one side of the tool holder assembly 2 away from the adjustable chassis 3. The power assembly 8 is located above the locking cylinder 11. The power assembly 8 uses a servo motor. A pulley 9 is fixedly installed on the output end of the servo motor and one end of the shaft 4. A transmission belt rope 10 is sleeved on the outer side of the pulley 9. The servo motor can drive the pulley 9 and the transmission belt rope 10 to rotate, and then the external circular knife 5 and the sharpening knife 6 rotate at a high speed.

[0027] See also Figure 1-4 Two groups of symmetrically arranged blocks 16 and limit switches 17 are respectively arranged on the surface of the bottom plate 1 and in front of the locking cylinder 11. A proximity switch 20 is fixedly installed on the side of the bottom plate 1 through a bracket, and the proximity switch 20 corresponds to the position of the electric shock plate 15. After the locking cylinder 11 is rotated, the electric shock plate 15 contacts the proximity switch 20, and the locking cylinder 11 will lock the core shaft 14.

[0028] See also Figure 1-4 The surface of the bottom plate 1 is hinged with a swing cylinder 18, and a slider 19 is fixedly installed at the other end of the swing cylinder 18. The slider 19 is fixedly connected to the outer wall of the tool holder assembly 2, and the slider 19 is located between the two groups of stoppers 16 and the limit switch 17. The swing cylinder 18 can drive the slider 19 to slide between the two limit switches 17. After the slider 19 contacts the limit switch 17, the swing cylinder 18 stops running.

[0029] See also Figure 1-4 The locking cylinder 11, the servo motor, the limit switch 17, the swing cylinder 18 and the proximity switch 20 are all connected to the PLC controller signal.

[0030] Working principle: When in use, the device is fixed on the machine tool through the base plate 1, and the tool holder assembly 2 is fixed on the base plate 1 through the mandrel 14, the locking cylinder 11 and the locking nut 12. The tool holder assembly 2 is equipped with a processed external circular knife 5, a sharpening knife 6, a protective cover 7 and a power assembly 8;

[0031] During operation, the selection of the sharpening knife 6 and the external circular knife 5 is realized by rotating the tool holder assembly 2 through the swing cylinder 18. When the slide block 19 rotates to the position of the stopper 16 and the slide block 19 contacts the limit switch 17, the swing cylinder 18 stops working.

[0032] When the locking cylinder 11 rotates to a specified position, the electric contact plate 15 contacts the proximity switch 20, and then the locking cylinder 11 locks the tool holder assembly 2 and stops working, and finally the corresponding tool is used to process the product.

[0033] This equipment expands the tool, so that the original two types of tool of the machine tool become three or four types of tool, realizes the expansion of the machine tool tool, and increases the processing capacity and range. Therefore, the processing of the emery roller product can be achieved by one clamping and one processing. The groove processing accuracy of the emery roller is greatly improved, and the processing efficiency is also improved, which also reduces the turnover and handling cycle and labor.

[0034] refer to Figure 3, the working condition of the external cylindrical cutter 5, the tool holder assembly 2 is pushed to the stopper 16 on the right side by the swing cylinder 18, and contacts the limit switch 17 on the right side through the slider 19, and then the swing cylinder 18 stops running, and the locking cylinder 11 will lock the 2 tool holder assemblies, so that the blade of the external cylindrical cutter 5 is longer than that of the grinder 6, which is convenient for using the external cylindrical cutter 5 to process the workpiece.

[0035] refer to Figure 4 , the working condition of the grinder 6, the tool holder assembly 2 is pushed to the stopper 16 on the left side by the swing cylinder 18, and contacts the limit switch 17 on the left side through the slider 19, and then the swing cylinder 18 stops running, and the locking cylinder 11 will lock the 2 tool holder assemblies. Since the outer diameter φ350 of the grinder 6 is larger than the outer diameter φ300 of the external cylindrical knife 5, the grinder 6 is used to grind the workpiece.

[0036] The two working conditions work alternately, realizing the operation of multiple tools on a single tool holder, indirectly realizing the increase and expansion of machine tool tools, and diversifying the processing of sanding rollers.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
