The mechanism of the utility model is mounted on the prior general thread-cutting lathe for achieving the automatization of the prior pipe thread processing.
Description
Technical field
The utility model belongs to Machine Design and manufacturing technology field, relates to a kind of Tool Control mechanism, be applicable in the lathe of cutting thread, can to realize cutter laterally, the length feed motion control.
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, usually adopt 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, realize the repair of screw thread again through feed repeatedly.
The work of repairing screw thread now on lathe all is manually to carry out, and owing to reasons such as the creeping of leading screw and guide rail, backlasses, makes the depth of cut be not easy to hold, and has influenced the accuracy of processing.In addition, the workman detects with ring screw gauge repeatedly in processing, the experience that tension amount (allowance) between ring gauge and the processed screw thread or clearance control mainly depend on the workman, and at this moment, machining accuracy and working (machining) efficiency depend primarily on workman's experience.
Summary of the invention
The purpose of this utility model is to provide a kind of mechanism that controls cutter traverse to, length feed motion, be arranged on the pipe threading machine, can make the repair action of wearing and tearing screw thread realize bigger automation, can not only improve crudy and working (machining) efficiency, and make machine tooling not rely on or depend on less workman's operating experience.
The technical scheme that the utility model adopted is, can control cutter traverse to, the mechanism of length feed motion, comprise the horizontal automatic feed mechanism and the length feed guiding mechanism that are fixed on the lathe cross slide, laterally automatic feed mechanism comprises the rolling guide that the knife rest bottom is fixing, knife rest can be moved on rolling guide, knife rest is driven by ball-screw, ball-screw is by the cog belt wheel drive of an Electric Machine Control, longitudinal feed mechanism is included in gathering sill fixing on the knife rest, in the gathering sill, expansion link and screw rod socket-connect, the rotation of screw rod can make expansion link slide in gathering sill, 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.
Mechanism of the present utility model is installed on the existing common tube thread chasing machine, adopt automatic feed mechanism to realize the horizontal auto-feed of lathe tool, promptly drive leading screw by motor (stepper motor, servomotor etc.), drive knife rest and do horizontal auto-feed campaign, the amount of feeding is controlled; Longitudinal feed mechanism can regulate that lathe tool is repaired relatively or the random position of button thread groove, realizes the tool setting when screw thread is repaired, its process be screw tool by the slip of expansion link in the cutter groove, realize the lengthwise position adjustment of cutter.
The utility model is on the basis of not destroying former machine tool structure, existing regular screw threads lathe is carried out functional promotion, realize the automation of gas thread processing, Installation and Debugging are convenient, the operating habit that meets the workman has improved the crudy and the working (machining) efficiency of common tube thread chasing machine.
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 utility model mechanism;
Fig. 3 is the structural representation of longitudinal feed mechanism in the utility model.
Among the figure, 1. profile of tooth belt wheel, 2. ball-screw, 3. flexible knife bar mechanism, 4. knife rest, 5. rolling guide, 6. base, 7. motor, 8. expansion link, 9. threading tool, 10. gathering sill, 11. screw rods, 12. handles.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
What Fig. 1 showed is threading tool 9 and the tool setting process that is repaired between the wearing and tearing screw thread, and promptly threading tool 9 will be aimed at the thread groove that is repaired the wearing and tearing screw thread or disorderly detains screw thread.
The utility model is the transformation of carrying out on existing common tube thread chasing machine, removed the small tool on the former lathe, the part of controlling at cutter has increased horizontal auto-feed and vertical guiding mechanism, can control the horizontal auto-feed campaign with screw tool of aligning of screw tool and screw thread.
Mechanism of the present utility model as shown in Figure 2, comprise the rolling guide 5 that knife rest 4 bottoms are fixing, knife rest 4 can be moved on rolling guide 5, knife rest 4 is driven by ball-screw 2, ball-screw 2 is driven by the profile of tooth belt wheel 1 of motor 7 controls, be fixed with gathering sill 10 on the knife rest 4, in the gathering sill 10, expansion link 8 socket-connects with screw rod 11, the rotation of screw rod 11 can make expansion link 8 slide in gathering sill 10, expansion link 8 stretches out an end retaining thread lathe tool 9 of gathering sill 10, and screw rod 11 stretches out an end fixed handle 12 of gathering sill 10, as shown in Figure 3.
By handle 12 rotating screw bolts 11, drive expansion link 8 and in gathering sill 10, slide.Because flexible knife bar mechanism installs at tool holder upper edge lathe longitudinal direction,, reach the purpose of tool setting so its function class like the small tool effect in the former lathe, promptly can be adjusted the position of screw tool by flexible cutter frame mechanism.
Operation principle of the present utility model and basic step are as follows:
(1) pass through flexible knife bar mechanism threading tool is installed, the tool setting when realizing repairing screw thread, at this moment point of a knife and thread groove centering after the tool setting end, are tightened the cutter holding screw on the knife rest, keep the invariant position of cutter (knife bar).
When (2) repairing screw thread, carry out feed, the tool backlash movement of cutter by horizontal automatic feed mechanism.
(3) generally to could realize the repair of screw thread, repeat the content of above-mentioned steps (2), up to process finishing through repeatedly feed.
