Description

A kind of vertical knee-type milling machine is with irregular blank workpiece clamping bench
Technical field
Clamping tool is machined the present invention relates to one kind, particularly a kind of vertical knee-type milling machine is with irregular blank workpiece clamping Platform.
Background technology
The blank of general machining, is typically to be manufactured by iron and steel foundries, its rough surface, each portion of appearance Position is concavo-convex uneven, it is necessary to the roughing for carrying out the first step is processed into smooth in appearance, the surface of size uniform or cylindrical, this The usual cutting output of roughing of sample is larger, only leaves fraction of surplus to finishing, virtually adds workload, extend work Make the time, however, when running into some single-sided process parts, according to conventional procedure of processing, another side must be also cut outer Circle is regular shape, is easy to clamping, wasting manpower and material resources, or in the workpiece of some distinctive appearances, it is not easy to clamping, clamping Not enough easily there is accident in power, and security threat is just brought to operating personnel.
Such as a kind of Patent No. 201220544391.X fast-clamping clamp for irregular workpiece, including fixture A groove for being used to load irregular workpiece is offered on body, the head of clamp body;It is additionally provided with the clamp body and irregular work Part shape matches and is used for the hole for placing the workpiece.The fixture can be greatly reduced clamping and set with the irregular workpiece of quick-clamping Fix time, reduce the probability of error, while clamping precision is also ensured, using more convenient.The fixture is using multiple default Clamping form, is only used for the workpiece pipeline system production and processing of same size, it is impossible to meet the workpiece of feature profile and size Clamping is used.
A kind of and for example fixture of the irregular long round parts of clamping of Patent No. 201120232075.4.The clamping is irregular The fixture of long round parts, including:Bottom plate, fixed mount and self-centering clamping component and coaxial positioning component.According to the present invention's Technical scheme, because the fixture has self-centering clamping component, can realize light clamping, while deforming workpiece, also Can be with resetting, precision is very high.Fixture is to carry out clamping using transformable clamping assembly, although meet each shape And the clamping workpiece requirement of size, still, its clamping dynamics is smaller, and the promptly degree to workpiece is low, can only be small-sized, light to some The workpiece of type carries out clamping, it is impossible to which large volume, heavy weight workpiece are used.
The content of the invention
The technical problem to be solved in the invention is to be directed to above-mentioned the deficiencies in the prior art, and provides a kind of vertical knee-type milling machine and use Irregular blank workpiece clamping bench.
In order to solve the above technical problems, the technical solution adopted by the present invention is:
A kind of vertical knee-type milling machine includes the workpiece slot of an opening upwards, the workpiece with irregular blank workpiece clamping bench Some screws are set on the side wall of groove, the one end being located in fix bar, the fix bar in workpiece slot is laterally set through screw It is provided with fastener;The fastener is included on the radially movable sleeve structure for being connected to fix bar, sleeve structure away from solid again Fixed pole one end is provided with clamp clip, and the clamp clip is hinged with sleeve structure, on the face that clamp clip is contacted with processing workpiece With bore spine;Positioned at the vertically arranged flexible pressure pin in workpiece slot inner bottom part center, the flexible pressure pin is contacted with processing workpiece One end be provided with bearing mechanism, the bearing mechanism includes upper synusia, and locating rod, base plate, the locating rod runs through upper strata Piece is connected with base plate;The workpiece slot top is provided with clamping layer, and the clamping layer is the structure with workpiece slot internal run-through, Connected between clamping layer and workpiece slot by swivel becket, moving jaw is set respectively on the upper one group of opposite side of the clamping layer.
As further preferred scheme, some fix bar vertical arrays were set to one group, around workpiece slot one week It is evenly distributed three groups, one of which is is fixedly installed, and two groups laterally movable are arranged in workpiece slot in addition.
As further preferred scheme, some horizontal banding slide rails, some bandings are set in the side wall of workpiece slot Slide rail is arranged in order and is set to two files from top to bottom in workpiece slot side wall, corresponds to the fixation of one group of activity respectively per file Bar;Being set in per ribbon slide rail has screw on movable component, movable component, have and movable component on every ribbon slide rail The position-limit mechanism interfixed;One movable fix bar of each movable component correspondence.
As further preferred scheme, the workpiece slot is vertical column structure.
As further preferred scheme, the clamp clip is semi-circular structure, and the radius of the clamp clip is 2mm- There is prominent rib on 5mm, the face that clamp clip is contacted with processing workpiece.
As further preferred scheme, at least three locating rods in the bearing mechanism.
Beneficial effect
A kind of vertical knee-type milling machine of the present invention is with irregular blank workpiece clamping bench, mainly by the way that processing workpiece is fixed on into work In part groove, irregular workpiece is clamped by the fix bar in each orientation jointly, the pressure pin that stretches provides the back strut power of milling, dress from bottom Interlayer carries out strength clamping as standby to irregular workpiece;Specifically have the advantages that:
1. the multi-faceted fix bar set from top to bottom, can meet and irregular workpiece is clamped in multiposition, by It is small in the contact point of fix bar, the deficiency of workpiece clamp holding force is made up using the fix bar of multi-quantity, furthermore it is possible to laterally movable Fix bar can more adjust the optimal clip position of selection, reach that chucking power is maximum, the best purpose of effect.
2. flexible pressure pin gives the support force of workpiece bottom-up, cancelled out each other for the lower pressure with milling, it is to avoid Downward pressure is excessive and offsets workpiece slide downward, cutting precision is influenceed, moreover, at least three positioning in bearing mechanism Bar, can meet the support of the irregular contour of workpiece bottom.
3. the clamp clip of semi-circular structure can coordinate the radially movable sleeve structure for being connected to fix bar, in clamp clip contact When being clamped on workpiece, clamp clip can be according to workpiece configurations, and select the position that is most preferably contacted with workpiece, on the one hand can carry High frictional force, it can in addition contain avoid workpiece from ejecting.
4. being connected between clamping layer and workpiece slot by swivel becket, clamping layer can be made freely to rotate on the irregular workpiece of selection The position most preferably clamped, so that large area clamping workpiece, further consolidates clamping workpiece.
5. the present invention is said from environmental protection and energy saving angle, the procedure of processing due to blank without first of Workpiece shaping, therefore Volume can be reduced accordingly when manufacturing blank, save metal consumption.
