A kind of quick change clamping press plate mechanism
The invention belongs to machinery manufacturing industry technical fields to be suitable for IC more particularly to a kind of quick change clamping press plate mechanism
With the continuous development of mechanical processing manufacturing technology, the performance of all kinds of lathes is also constantly being promoted, and is filled to technique
Standby demand but simplicity, generalization and high efficiency increasingly.Presser type hold-down mechanism is machining process equipment positioning pressure
The most commonly used one of method, is widely used general in tight mode.The hold-down mechanism packaging efficiency now generally used is low, dismounting
It is dumb, processing efficiency is seriously affected in batch production, novel quick change presser type hold-down mechanism can greatly improve mechanical processing work
The equipment efficiency of skill equipment, can be from solving the problems, such as this at all.
The purpose of this utility model is to provide a kind of quick change clamping press plate mechanism, and processing is simple, and packaging efficiency is high, practicability
By force, compression mode is stablized, and can be applied in being machined multi-process.
To achieve the goals above, the technical solution adopted in the utility model is：
A kind of quick change clamping press plate mechanism, including fast resleeve, quick change screw rod, pressing plate, auxiliary support bar, nut, limit
Pin, spring；Fast resleeve is cylindrical, and middle part is equipped with ellipse hole, and bottom is equipped with and is arranged with two convex gears of sector；Quick change spiral shell
Bar lower part is equipped with oval holding block, and middle part is equipped with spacer pin, and top is equipped with external screw thread；Pressing plate is equipped with circular hole, is socketed in fast
It changes on screw rod, pressing plate bottom passes through spring and spacer pin apical grafting；Pressing plate top is fixed by being screwed on quick change screw rod top nut；Pressing plate
On also set and be screwed with auxiliary support bar.
Quick change screw rod top end is square cylinder.
The beneficial effects of the invention are as follows：
1. the assembling of utility model quick change presser type hold-down mechanism is simple, auxiliary support bar and pressing plate are threadedly coupled, pressed
Plate is connect with screw rod with nut, is formed integral structure, is rotated by 90 ° after screw head is penetrated fast resleeve, makes screw head side
Plane is bonded with fast resleeve limited block, keeps lock-out state, by nut check above pressing plate, realize hold-down mechanism quick group
2. the dismounting of utility model quick change presser type hold-down mechanism is simple, screw rod will be rotated 90 after nut loosening above pressing plate
Degree makes screw head plane limit plane keeping parallelism with fast resleeve, you can takes out pressing plate overall structure together, improves pressure
The disassembly efficiency of locking structure.
3. the utility model can meet slewing parts internal-and external diameter and many types of surface parts process the compression of different end faces, realize
The rapid translating in different positioning compression faces improves technological preparation efficiency.
4. the utility model processing is simple, a whole set of quick change presser type hold-down mechanism is without processing difficulties, conventional equipment Milling Machining
It can be completed.The cost of material is low, can use common No. 45 steel material, highly practical, multiplexing kind and multi-process in can be used for being machined,
Without limitation use condition.

Specific implementation mode
The utility model is described in detail in conjunction with attached drawing 1-6 and reference numeral.
A kind of quick change clamping press plate mechanism, including fast resleeve 1, quick change screw rod 2, pressing plate 3, auxiliary support bar 4, nut 5,
Spacer pin 6, spring 7；
Fast resleeve 1 is cylindrical, and middle part is equipped with ellipse hole, and bottom is equipped with and is arranged with two convex gears of sector；
2 lower part of quick change screw rod is equipped with oval holding block, and middle part is equipped with spacer pin 6, and top is equipped with external screw thread；
Pressing plate 3 is equipped with circular hole, is socketed on quick change screw rod 2,3 bottom of pressing plate passes through spring and 6 apical grafting of spacer pin；Pressing plate
3 tops are fixed by being screwed on 2 top nut 5 of quick change screw rod；
It is also set on pressing plate 3 and is screwed with auxiliary support bar 4.
2 top end of quick change screw rod is square cylinder.
Often occur the more planes of single process in mechanical processing, machined surface cannot be used to compress simultaneously, to produce
Raw to need to be replaced frequently hold-down mechanism, a seal face needs multiple pressing plates to compress again, therefore the packaging efficiency of hold-down mechanism is direct
Influence the processing efficiency of product.
Bushing is mounted in mating fixture base, is locked with M5*8 holding screws, anti-rotation.
It again by Anchor plate kit, is inserted into bushing along elliptical slot, then 90 degree of rotations, you can locking.
It only needs that with the square cylinder above spanner counterclockwise loose screw rod, Anchor plate kit is integrally laid down when relief panel.
