The auxiliary clamping device used in processing, or applied to other axial vertical core processing with similar small sized product.
Background technology
At present, some products processing when, it is necessary to by workpiece be arranged on positioning reference plane lower section, clamp when need behaviour
Make personnel's workpiece dominated by hand, workpiece is then clamped again, carry out machining after clamping again.In clamping workpiece and clamping, by
Workpiece is held in a hand, another hand will press switch and clamp, often due to the clamping switch on workpiece and guidance panel
It is distant, so operating personnel can not complete both to hold workpiece, the operation that switch is clamped is pressed again.With automobile plunger type
Exemplified by master cylinder product, the product has vertical core equidimension to need processing, the processing generally used in production and processing on axial direction
Mode is：On vertical numerical control process equipment, by product clamping on special fixture, workpiece locating surface and fixture locating surface connect
Touch, workpiece is located at below fixture locating surface, and vertical core position exposes fixture locating surface, by Hydraulic Clamping Mechanism by Workpiece clamping
When, due to no auxiliary clamping device, one hand of operating personnel will hold workpiece, prevent workpiece from departing from fixture, and another hand is needed
Remove to press the hydraulic selector on machine operation panel, and having on machine operation panel apart from operating area farther out, operation
Personnel reach panel, it is impossible to complete pinching action, and the clamping to workpiece brings inconvenience.
The content of the invention
The present invention provides a kind of auxiliary clamping device of axial vertical core processing, is produced with solving the vertical core class with flange feature
When product are produced and processed, clamping workpiece can not keep it in positioning and clamping position, be easily separated from locating surface, it is impossible to clamp workpiece and work
Stability and reliability is poor during part clamping, and operating personnel are easy to operate, the problem of labor intensity is low.
The technical scheme is that：, close to the position of upper plate, there are two keyways on top on the inside of two risers,
Gripping block is respectively provided with keyway, gripping block there are two counter sinks, and two hexagon socket head cap screws are each passed through the counter sink of gripping block,
It is connected through a screw thread with riser, and uses nut check hexagon socket head cap screw, spring retainer pin is mounted in the limit pin hole of gripping block,
Adjustment bolt is connected through a screw thread on riser, there is spring retainer hole on the head of adjustment bolt, and compression spring one is mounted in
In spring retainer pin, other end is in the spring retainer hole on adjustment bolt head, and gripping block ramp angle [alpha] is at 40-45 °
Between, lower inclined plane angle beta is between 60-65 °, and two sides connects circular arc radius surface between R2.0-R3.0.
The advantage of the invention is that：Structure is novel simple, and one-handed performance can be realized in clamping workpiece, reduces operation step
Suddenly, clamping workpiece is stable, and clamping workpiece is reliable, adjusts simple and convenient.

Embodiment
, close to the position of upper plate, there are two keyways 41 on top two inner sides of riser 4, are respectively provided with keyway 41
Gripping block 2, gripping block 2 has two counter sinks 24, and two hexagon socket head cap screws 1 are each passed through the counter sink 24 of gripping block 2, and riser
4 are connected through a screw thread, and lock hexagon socket head cap screw 1 using nut 5, and spring retainer pin 3 is mounted in the limit pin hole 25 of gripping block 2
Interior, adjustment bolt 6 is connected through a screw thread on riser 4, there is spring retainer hole 61, compression spring 7 on the head of adjustment bolt 6
One is mounted in spring retainer pin 3, and other end is in the spring retainer hole 61 on the head of adjustment bolt 6, the ramp 21 of gripping block 2
Angle [alpha] between 40-45 °, the angle beta of lower inclined plane 22 between 60-65 °, two sides connect the radius of arc surface 23 R2.0-
Between R3.0, be so conducive to clamping workpiece and unloading, two auxiliary clamping devices are when loading workpiece, and workpiece is along gripping block
2 lower inclined plane 22 loads workpiece position location upwards, and gripping block 2 is slided respectively along hexagon socket head cap screw 1 to outside fixture, workpiece dress
Clip to behind position, workpiece is in the position of ramp 21 of gripping block 2, gripping block 2 is breakked away into fixture under spring force
Dynamic, by Workpiece clamping, hand is left after workpiece, and workpiece will not drop because of own wt.
Operation principle：Illustrate that it is applied so that auxiliary clamping device is arranged on special fixture as an example, the special fixture is
The fixture of automobile plunger type master cylinder product is processed, there are the geomeries such as vertical core on the axial location of plunger-type brake master cylinder
It is required that processing.This fixture is used in pairs, by identical fixture or so two parts not An Zhuan machine tool two ends, two stand
Plate 4 is connected with upper plate 8 and bottom plate 13 respectively, and hydraulic clamp oil cylinder 12 is arranged on clamp bottom board 13, and top 11 in release position
Put, left and right riser 4 is arranged on bottom plate 4, and the two ends of upper plate 8 and riser 4 are connected, the top two inner sides of riser 4, close to upper plate
Position, have two keyways 41, gripping block 2 be respectively provided with keyway 41, gripping block 2 can be slided in keyway 41, two
