Description

Technical Field

[0001] This utility model relates to the technical field of printing roller processing equipment, specifically to a multi-head tool holder for processing printing rollers. Background Technology

[0002] A printing roller is a type of printing mold. Printing roller processing requires surface finishing, such as machining the inner hole, inner chamfer, outer chamfer, end face, and outer fillet of the workpiece. Currently, commonly used cutting tools include square and peach-shaped tools. Square tools can only be used for machining the inner hole, inner chamfer, and outer chamfer, while peach-shaped tools are mainly used for machining the end face and outer fillet. Currently, the tool holders used for machining printing rollers are all single-head tool holders. During machining, it is necessary to consider the workpiece structure, as shown in the attached diagram. Figure 1 As shown, when machining the inner hole, inner chamfer, and outer chamfer of a workpiece, square inserts are required. When machining the end face and outer fillet of a workpiece, peach-shaped inserts must be replaced. A single-head tool holder cannot meet the needs of rapid machining, which seriously affects machining efficiency and accuracy, resulting in low efficiency. Utility Model Content

[0003] This invention provides a multi-head tool holder for processing printing rollers, which solves the problem in the prior art where the use of a single-head tool holder requires frequent replacement of different blades, affecting the processing efficiency and accuracy of printing rollers.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A multi-head tool holder for processing printing rollers includes a tool holder body, a square blade station, and several peach-shaped blade stations. The square blade station consists of a square blade and a fastening screw. The square blade is fixed to the end of the tool holder body by the fastening screw. The peach-shaped blade station consists of a peach-shaped blade pad, a peach-shaped blade, a positioning post, a pressure plate, and a pressure plate screw. The peach-shaped blade is placed on the peach-shaped blade pad and then fixed to the end of the tool holder body by the positioning post. The pressure plate is fixed to the tool holder body by the pressure plate screw, and the end of the pressure plate presses against the top of the peach-shaped blade.

[0006] This utility model integrates square and peach-shaped cutting tools on a multi-head tool holder. The square cutting tool is mainly used to process the inner hole, inner chamfer, outer chamfer, and end face of the workpiece; the peach-shaped cutting tool is mainly used to process the outer fillet of the workpiece. Thus, the inner chamfer, inner hole, outer chamfer, end face, and outer fillet are processed in one go, which significantly improves the overall processing effect and efficiency, increases processing efficiency and accuracy, and reduces labor costs.

[0012] Example 1

[0013] like Figure 1 and Figure 2 As shown, a multi-head tool holder for processing printing rollers includes a tool holder body 1, a square blade station, and two peach-shaped blade stations. The square blade station consists of a square blade 4 and a fastening screw 8. The square blade 4 is fixed to the end of the tool holder body 1 by the fastening screw 8. The two peach-shaped blade stations are respectively composed of a peach-shaped blade pad 7, a peach-shaped blade 5, a positioning post 6, a pressure plate 2, and a pressure plate screw 3. The peach-shaped blade 5 is placed on the peach-shaped blade pad 7 and then fixed to the end of the tool holder body 1 by the positioning post 6. The pressure plate 2 is fixed to the tool holder body 1 by the pressure plate screw 3, and the end of the pressure plate 2 presses against the top of the peach-shaped blade 5.

[0014] This utility model's multi-head tool holder features a square insert primarily for machining workpiece inner holes, inner chamfers, and outer chamfers; one peach-shaped insert primarily for machining workpiece end faces; and another peach-shaped insert primarily for machining workpiece outer fillets. This allows for the simultaneous machining of inner chamfers, inner holes, outer chamfers, end faces, and outer fillets. Each insert machined one surface, resulting in more durable inserts with a longer lifespan, reduced replacement frequency, higher machining efficiency, and a compact structure.

[0015] Example 2

[0016] like Figure 1 and Figure 3 As shown, a multi-head tool holder for processing printing rollers includes a tool holder body 1, a square blade station, and a peach-shaped blade station. The square blade station consists of a square blade 4 and a fastening screw 8. The square blade 4 is fixed to the end of the tool holder body 1 by the fastening screw 8. The peach-shaped blade station consists of a peach-shaped blade pad 7, a peach-shaped blade 5, a positioning post 6, a pressure plate 2, and a pressure plate screw 3. The peach-shaped blade 5 is placed on the peach-shaped blade pad 7 and then fixed to the end of the tool holder body 1 by the positioning post 6. The pressure plate 2 is fixed to the tool holder body 1 by the pressure plate screw 3, and the end of the pressure plate 2 presses against the top of the peach-shaped blade 5.

[0017] The square blade of this utility model's multi-head tool holder is mainly used to process the inner hole, inner chamfer, outer chamfer, and end face of the workpiece; the peach-shaped blade is mainly used to process the outer fillet of the workpiece. It can process the inner chamfer, inner hole, outer chamfer, end face, and outer fillet in one go. At the same time, it can process different positions, with high precision controllability and greatly improved efficiency. The two blades are integrated and installed in a compact manner, which can further expand the processing range.
