Abstract
The utility model discloses a telescoping cutter holder mechanism which is suitable for a pipe threading machine. The telescoping cutter holder comprises a guiding groove, wherein, in the guiding groove, a telescopic link is sleeved and connected with a screw rod, the telescopic link can slide in the guiding groove by the rotation of the screw rod, a thread cutting tool is fixed at one end where the telescopic link extends out of the guiding groove and a handle is fixed at one end where the screw rod extends out of the guiding groove. The mechanism of the utility model can be arranged on the prior numerical control pipe threading machine or numerical control reconstruction pipe threading machine. The functional expansion is carried out to the prior numerical control pipe threading machine with convenient installation and debug and adjustment freedom degree. The handle drives the screw rod, thereby realizing the vertical adjustment to the thread cutting tool, and achieving the aim of the operation of the thread screw to the tool.
Description
Technical field
The utility model belongs to Machine Design and manufacturing technology field, relates to a kind of flexible knife bar mechanism, is applicable in the pipe threading machine, can realize screw tool and the automatic tool preset that is repaired screw thread.
Background technology
For some often screw, stressed bigger taper pipe thread pair, as joint of petroleum drill rod, comings and goings instrument etc., its internal and external threads (pin thread and box) is easy to wear.In order to recover screw thread pair, normally on the basis of original wearing and tearing screw thread, with the external diameter (external screw thread) of screw thread and internal diameter (internal thread) car to certain size, then by tool setting, be about to threading tool and aim at thread groove, could realize the repair of screw thread again through feed repeatedly.
Present common tube thread chasing machine, its tool setting action is to realize by the small tool of lathe; And numerical control pipe thread lathe owing to lack small tool, can't carry out the tool setting operation, thereby is difficult to realize the repair of gas thread.
Summary of the invention
The purpose of this utility model is to provide a kind of flexible knife bar mechanism, can be arranged on the square tool post of numerically controlled lathe and numerical control transformation lathe, in the repair of screw thread, realizes the tool setting action, also can realize the disorderly tool setting operation during button of screw thread.
The technical scheme that the utility model adopted is, a kind of flexible knife bar mechanism that is applicable to pipe threading machine, comprise gathering sill, in the gathering sill, expansion link and screw rod socket-connect, the rotation of screw rod can make expansion link slide in gathering sill, and expansion link stretches out an end retaining thread lathe tool of gathering sill, and the end that screw rod stretches out gathering sill is fixed with handle.
Flexible knife bar of the present utility model mechanism makes screw tool by the slip of expansion link in the cutter groove, regulates the position of lathe tool phase tool setting groove, by the adjustment of cutter lengthwise position, realizes the tool setting when screw thread is repaired, or the disorderly tool setting operation during button of screw thread.
The utility model carries out the function expansion to existing numerical control pipe thread lathe on the basis of not destroying former machine tool structure, tool setting when realizing that gas thread is repaired, or the disorderly tool setting operation during button of screw thread.Installation and Debugging are convenient, meet workman's operating habit, improved the function of use of numerical control pipe thread lathe.
Description of drawings
Fig. 1 is threading tool and is repaired the tool setting of wearing and tearing between the screw thread and concerns schematic diagram.
Fig. 2 is the structural representation of the flexible knife bar mechanism of the utility model.
Among the figure, 1. expansion link, 2. threading tool, 3. gathering sill, 4. screw rod, 5. handle.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
What Fig. 1 showed is threading tool 2 and the tool setting process that is repaired between the wearing and tearing screw thread, and promptly threading tool 2 will be aimed at the thread groove that is repaired the screw thread that weares and teares.
Flexible knife bar of the present utility model mechanism is fixed on the knife rest of existing numerically controlled lathe, as shown in Figure 2, comprise gathering sill 3, in the gathering sill 3, expansion link 1 socket-connects with screw rod 4, the rotation of screw rod 4 can make expansion link 1 slide in gathering sill 3, and expansion link 1 stretches out an end retaining thread lathe tool 2 of gathering sill 3, and the end that screw rod 4 stretches out gathering sill 3 is connected and fixed handle 5.
By handle 5 rotating screw bolts 4, drive expansion link 1 and in gathering sill 3, slide, the tool setting operation when tool setting operation when realizing repairing screw thread or screw thread are disorderly detained, at this moment point of a knife and thread groove centering, tool setting after finishing is tightened the cutter holding screw on the knife rest, keeps the invariant position of cutter (knife bar).
The utility model is mounted on the square tool post of existing numerical control pipe thread lathe and numerical control transformation pipe threading machine, because flexible knife bar mechanism installs at tool holder upper edge lathe longitudinal direction, so its function class is like the small tool effect in the former lathe, promptly can adjust the position of screw tool, reach the purpose of tool setting by flexible cutter frame mechanism.
