Abstract

The utility model discloses an automatic retract thread processing equipment, which is characterized in that the equipment consists of a movable part and a static part. The movable part has a rotational tool rest; the tool rest ball hole inosculates the locking pin, guaranteeing the cutting tool to aim at the lathe spool thread throughout, rotation cannot happen because of the contact of the tool rest and the latch plane. The static part is a fixed but adjustable backstop. The beneficial effects of the static part are that the structure is ingenious and is of scientific, the organization is nimble, the knife automatic drawing back is accurate; the operation is simple and convenient, thoroughly settled the problem caused by artificial operation fault collision and rejection. When processing, the arresting pin contacts with the backstop, the arresting pin compression spring separates from the tool rest, the tool rest loosens and drops immediately under the cutting pressure function, and the cutting tool is separated from the work piece automatically. After the tool rest dropping, the arresting pin slides across the tool rest, to eliminate the cutting pressure thrust force and stops, re-hold the tool rest until being matched and fixed with the locking pin, and then continue a next time thread cutting.

Description

But a kind of screw thread processing unit (plant) of automatic withdrawal

Technical field

The utility model relates to a grade machine tooling technology, is a kind of automatic tool retracting unit, but a kind of screw thread processing unit (plant) of automatic withdrawal specifically.

Background technology

Lathe often causes colliding or product rejection because of operate miss when screw thread processing withdrawing at present.

Summary of the invention

But the purpose of this utility model provides a kind of screw thread processing unit (plant) of automatic withdrawal.

Technical solution of the present utility model is: but a kind of screw thread processing unit (plant) of automatic withdrawal, it is characterized in that: device is made up of dynamic and static two parts, moving part has rotating knife rest, sphere hole on the knife rest is aimed at the lathe axis all the time with the identical cutter that guarantees of lock pin, and knife rest and latch plane contact are in order to avoid rotate.Stationary part has stop, and the stop fixed-site is adjustable.

The beneficial effects of the utility model are: structure ingenious science, and mechanism is flexible, and automatic withdrawal is accurate, and is easy and simple to handle, solved thoroughly that the human operational error causes colliding and the problem of waste product.Add man-hour, when latch contacts with backstop, latch compression spring breaks away from knife rest, and knife rest unclamps and descends immediately under the effect of cutting pressure, makes cutter break away from workpiece automatically.After knife rest descended, latch slipped over knife rest, will eliminate and be parked in this position from the thrust of cutting pressure, recur to knife rest and lock pin coincide fix till, continuation screw chasing next time again.

Below in conjunction with the accompanying drawings and embodiments the utility model is further described:

Description of drawings

But accompanying drawing is the structural representation of the screw thread processing unit (plant) of a kind of automatic withdrawal of the present utility model:

The specific embodiment

Accompanying drawing has been described an embodiment of the present utility model, in this embodiment, comprises dynamic and static two parts: moving part has the knife rest A of rotation.Latch E.Lock pin F.Stop screw D; Quiet part has backstop C.The part B of backstop is installed.

Operation principle of the present utility model

Add man-hour, when latch contacts with backstop, latch compression spring breaks away from knife rest, and knife rest unclamps and descends immediately under the effect of cutting pressure, makes knife rest break away from workpiece automatically.After knife rest descended, latch slipped over knife rest, will eliminate and be parked in this position from the thrust of cutting pressure, recur to knife rest and lock pin coincide fix till, continuation screw chasing next time again.

Claims

But 1. the screw thread processing unit (plant) of an automatic withdrawal, it is characterized in that: divide dynamic and static two parts, moving part has rotating knife rest, and knife rest coincide to guarantee to aim at all the time the axis of lathe by sphere hole on it and lock pin.
2. but according to the screw thread processing unit (plant) of right 1 described a kind of automatic withdrawal, it is characterized in that: knife rest contacts by face with latch and does not rotate, and its latch has stop screw to fix.
3. but according to the screw thread processing unit (plant) of right 1 or 2 described a kind of automatic withdrawals, it is characterized in that: quiet part has the adjustable stop in fixed position.
