The invention discloses a kind of key milling Fixture for internal tooth, comprise base plate, be arranged on the left adjustable plate on base plate and right adjustable plate, described left adjustable plate and right adjustable plate are respectively provided with air cylinder fixed plate and installing plate, described air cylinder fixed plate is provided with cylinder, installing plate is provided with key positioner block, key positioner block is provided with key resettlement groove, the right side that key positioner block is positioned at key resettlement groove has rectangular through holes; Described installing plate is provided with rectangular channel, lays compact heap in rectangular channel, compact heap is provided with compressed part, compressed part is placed in rectangular through holes, is provided with connecting rod between described compact heap and cylinder, and described connecting rod is threaded with cylinder.The invention solves the problem that traditional keys clamp power is inadequate, and can regulate for different key sizes, meet the clamping requirement of different key.Key clamping field can be widely used in.
Description
Technical field
The present invention relates to clamp fixture field, especially relate to a kind of key milling Fixture for internal tooth.
Background technology
When milling internal tooth wanted by key, need enough stable, therefore, need fixture to possess enough clamping forces, meet the stability requirement of key in processing.And for meeting the process requirements of different size key, fixture needs to facilitate adjustable.
Original key gear milling clamper mechanism, in saltation layer process, milling is unstable all the time, and debugging is wasted time and energy, and scrappage is high.There is following problem simultaneously:
1. pincers worker die change debug difficulties.
2. clamp parts clearance is large, precision is not high, cause that key face is out-of-level, flute profile thickness is inconsistent after clamping.
3. clamp power is little, and milling temperature is large, and key moves, flute profile dimension overproof.
4. machine spindle centre-to-centre spacing is inconsistent, and frock can only design by special plane.
Summary of the invention
The object of this invention is to provide a kind of key milling Fixture for internal tooth, solve existing key milling Fixture for internal tooth fixing unstable, regulate inconvenient problem.
The technical solution adopted for the present invention to solve the technical problems is: a kind of key milling Fixture for internal tooth, comprise base plate, be arranged on the left adjustable plate on base plate and right adjustable plate, described left adjustable plate and right adjustable plate are respectively provided with air cylinder fixed plate and installing plate, described air cylinder fixed plate is provided with cylinder, installing plate is provided with key positioner block, key positioner block is provided with key resettlement groove, the right side that key positioner block is positioned at key resettlement groove has rectangular through holes; Described installing plate is provided with rectangular channel, lays compact heap in rectangular channel, compact heap is provided with compressed part, compressed part is placed in rectangular through holes, is provided with connecting rod between described compact heap and cylinder, and described connecting rod is threaded with cylinder.
For convenience of the centre-to-centre spacing between regulated quantity key, described base plate is provided with chute, left adjustable plate and right adjustable plate are placed in chute, stage clip is provided with between left adjustable plate and right adjustable plate, the two ends of described base plate are respectively provided with a regulating block, regulating block is provided with hold-down bolt, and hold-down bolt is pressed on the side of left adjustable plate and right adjustable plate.
For ensureing that left adjustable plate and right adjustable plate do not slide when saltation layer, the both sides that described base plate is positioned at left adjustable plate are respectively provided with a latch segment, the both sides of right adjustable plate are also respectively provided with a latch segment, latch segment is " 7 " font structure pressing plate, and latch segment is pressed on left adjustable plate and right adjustable plate.
Further, described left adjustable plate and right adjustable plate are respectively provided with two waist-shaped holes, base plate suitable is with it provided with bolt hole.
For convenience of quickly calibrated installation key, described installing plate is provided with the reference block that Key is aimed at, reference block is positioned at the rear end of key resettlement groove.
Beneficial effect of the present invention: apply pressure to compact heap by cylinder, thus make compact heap compress key, because the pressure ratio of cylinder is comparatively large, and can be continual and steady provide pressure, so fastening effect is better.Meanwhile, for different keys, the position of the compact heap of this fixture can regulate, easy to adjust.Described left adjustable plate and right adjustable plate movable, facilitate the centre-to-centre spacing between adjustment two key, met the requirement of different key post-production.This fixture is easy to adjust, and applicability is good.
Below with reference to drawings and Examples, the present invention is described in detail.
