Description

Technical Field

[0001] The invention relates to the technical field of lathe processing equipment accessories, and in particular to a special tool holder for processing a disk part of a CNC crank vertical lathe. Background Art

[0002] The tool rest of the CNC crank vertical lathe is a plate-shaped structure, arranged horizontally, and a turning tool is installed on the top of the tool rest to turn the workpiece. When processing some large-diameter disc-like workpieces on the CNC crank vertical lathe, the parts of the workpiece that need to be processed are the upper and lower planes of its outer circle and outer ring. However, when the diameter of the workpiece exceeds the processing range of the machine tool, the tool rest of the machine tool is installed with the turning tool and moves to the maximum distance in the X direction, which still cannot meet the diameter processing range requirements of the workpiece. It is impossible to turn the outer circle or outer end face of the workpiece, and there is no suitable tool to cross the workpiece to process the lower side of the workpiece.

The tool holder clamping part above the connecting plate of the tool holder is used for clamping and connecting the tool holder and the lathe, and is fixed by bolts passing through the bolt holes, the connecting plate offsets the turning tool mounting part below the opening side of the tool holder clamping part, moves the position of the turning tool mounting part forward along the X-axis direction, and sets a turning tool fixing groove to install the turning tool, so that the diameter range that can be processed is increased.

[0004] Furthermore, a second turning tool fixing groove is provided at the inner bottom of the turning tool mounting portion, and a row of fastening bolts is also provided on one side of the groove wall of the second turning tool fixing groove. The second turning tool fixing groove is provided at the bottom side of the turning tool mounting portion for mounting the second turning tool, so that the upper surface and the lower surface of the outer circle of the workpiece can be turned at the same time during processing, and the processing efficiency is higher.

[0005] Furthermore, a row of mounting holes is provided on the side plate of the tool holder clamping portion, and connecting ears are welded correspondingly on the outer side of the top plate of the tool holder clamping portion and the outer side of the tool holder clamping section of the connecting plate, and are respectively provided with penetrating ear holes, and bolt connection holes are respectively provided at the end of the top plate and the tool holder clamping section of the connecting plate.

[0006] Furthermore, the connection plate is connected to a reinforcing plate at one end of the knife holder clamping portion, and the reinforcing plate is attached to the outer side of the side plate of the knife holder clamping portion. The reinforcing plate enhances the stability of the connection between the knife holder clamping portion as a whole and the connection plate.

[0007] Furthermore, the connecting plate is connected to an L-shaped rib plate at one end of the tool mounting portion, and the L-shaped rib plate is arranged downward and attached to the outer side of the back plate and the bottom plate of the tool mounting portion. The L-shaped rib plate increases the overall connection stability between the connecting plate and the lower tool mounting portion.

[0008] Compared with the prior art, the advances of the special tool holder for CNC crank vertical lathe processing disc parts designed by the patented design of the present invention are that, firstly, the tool holder is designed as an S-shape as a whole, and the position of the turning tool mounting part is moved forward in the positive direction of the X-axis through a long middle connecting rod, which effectively increases the processing diameter range of the lathe; secondly, the turning tool mounting part of the tool holder is provided with upper and lower turning tool mounting grooves, on which the upper and lower turning tools can be installed at the same time, and the upper and lower side surfaces of the outer circle of the disc part can be turned at the same time, which effectively improves the processing efficiency; in addition, the side plates, top plates and connecting plates of the tool holder mounting part are provided with mounting holes, connecting ears and bolt connecting holes, a total of three connection and fixing methods, to ensure the installation stability of the tool holder; finally, reinforcing plates and L-shaped rib plates are respectively provided at both ends of the middle connecting plate to support and strengthen the tool holder clamping part and the turning tool mounting part connected at both ends, so that the overall structure of the tool holder is more stable.
