Abstract
The utility model discloses a miller jig, which comprises a T-shaped seat used for being connected with a miller base plate, and a jig body in bolt connection with the T-shaped seat, wherein screwed holes penetrating the jig are formed in a side surface of the jig body; compress bolts are arranged in the screwed holes; and compress blocks are arranged at the head parts of the compress bolts. The working principle of the miller jig is as follows: after a workpiece is placed on the miller base plate, all that is needed is to fix the jig in a miller base plate groove on the periphery of the workpiece, and screw compress bolts to enable the compress blocks to prop against a side surface of the workpiece. As a result, the integral plane surface of the workpiece is processed, and a secondary clamping and processing are dispensed. The miller jig has the following benefits: one-step clamping can mill and process the integral plane surface of the workpiece, and the machining precision and processing quality are ensured.
Description
Technical field
The utility model relates to a kind of fixture, relates in particular to a kind of fraise jig.
Background technology
Planer-type milling machine is broad-spectrum heavy machine tool, and planer-type milling machine machining accuracy and productivity ratio are all higher, is adapted at reaching in batch plane and the inclined-plane of machining large workpiece in production in enormous quantities, is applicable to large-scale sheet metal component or the processing such as casing part and mould.Gantry mill is in the middle of the process of the large plane steel plate of processing, at first for the first time clamping, most of area machine-shaping of steel plate, because common fixture is all the compression type fixture, the position of clamp pressing for the first time can't Milling Process, then by the clamping that replaces for the second time, the position milling of clamp pressing for the first time, the flatness processed through the large plane steel plate of clamping Milling Process moulding for the second time like this is not good, all the step with the tool marks junction exists, and has a strong impact on machining accuracy and crudy.
Chinese patent Granted publication number: CN202399062U, August 29 2012 Granted publication day, a kind of fraise jig group is disclosed, comprise at least two for holding workpiece and be located at the fixture on the substrate of milling machine, fixture comprises positioner, positioner comprises pressing plate and the first support column, and the bottom of the first support column is located on the substrate of milling machine; One end of pressing plate is located on the first support column, and the place, top of workpiece is located in the opposite end of pressing plate; Fixture also comprises at least one vibration absorber of being located on substrate and being resisted against the workpiece bottom.Cutter for milling machines is in processing work when surface, due to the effect of cutting force, and the workpiece vibration-generating, at this moment vibration absorber can absorb the energy of Workpiece vibration, thereby makes the workpiece held stationary.This fixture can be fixed on workpiece on the substrate of milling machine preferably, and vibration absorber is supporting workpiece simultaneously, has reduced the vibration of workpiece in process.Its weak point is that this kind of fixture understood on some machined surface that is pressed in workpiece in clamping, after processing, the position of clamp pressing can't complete Milling Process for the first time, need clamping processing for the second time, easily there is step in surface of the work through twice clamping processing in the tool marks junction, cause that surface of the work is rough, out-of-flatness, have a strong impact on crudy and machining accuracy.
The utility model content
The utility model is pressed on surface of the work the surface that causes workpiece and need to just can completes the processing on whole surface through twice clamping Milling Process in order to overcome fraise jig of the prior art, thereby can produce in the tool clear of work junction deficiency that step has a strong impact on machining accuracy and crudy after twice clamping processing, provide a kind of to need clamped one time just can complete the Milling Process of surface of the work, thereby guaranteed the fraise jig of crudy and machining accuracy.
To achieve these goals, the utility model adopts following technical scheme:
A kind of fraise jig, comprise T shape seat for being connected with the milling machine substrate and and the bolted chuck body of T shape seat, the side of described chuck body is provided with the screwed hole of perforation, in described screwed hole, is provided with hold-down bolt, and the head of described hold-down bolt is provided with compact heap.T shape seat is put into the draw-in groove on the milling machine substrate, tight a bolt and make chuck body and T shape seat be fixed on the milling machine substrate, fix several fixtures around workpiece, compact heap is withstood to the side of workpiece, then tighten hold-down bolt, compact heap on fixture has just been located Work-sheet pressing like this, can not be subject to the effect of fixture on to be processed of workpiece, therefore only need clamping once just can complete the Milling Process on the whole plane of workpiece, thereby guarantee crudy and machining accuracy, the out-of-flatness of the mismachining tolerance of avoiding secondary clamping to bring and tool marks junction.
As preferably, the cross section of described compact heap is right angled triangle, comprise the trailing flank that ,He bottom surface, bottom surface is vertical and the inclined-plane that connects bottom surface and trailing flank, the trailing flank of described compact heap is connected with the head of hold-down bolt, the bottom surface of described compact heap is parallel with the milling machine substrate, and the bottom surface of compact heap is provided with the support raised line.The tip portion of compact heap withstands side surface of workpiece, support raised line and milling machine substrate contacts, thereby make the tip of compact heap fix on the middle part of side surface of workpiece, more stable after holding out against, compact heap is inclined-plane near the face of workpiece, can effectively prevent the interference between cutter and compact heap.
As preferably, the head of described compact heap is fixed with wear plate.Wear plate hardness is high, wear-resistant, can increase the service life of fixture.
As preferably, on described chuck body, with the both sides of the junction of T shape seat, extend to form limited block.Just snap in T shape seat between two limited blocks, so can not mutually rotate between T shape seat and chuck body, guarantee can not cause because of the rotation between chuck body and T shape seat workpiece loosening after the fixture top tight workpiece.
As preferably, described hold-down bolt is provided with pre-load nut.After hold-down bolt is tightened, compact heap workpiece pressing side, then tighten the pre-load nut on hold-down bolt, prevents that workpiece is in process, and hold-down bolt becomes flexible and causes workpiece loosening.
As preferably, between the plane at described hold-down bolt and milling machine substrate place, structure in an angle.When turning hold-down bolt, existence due to angle, make the power acted on hold-down bolt resolve into two component, a component workpiece pressing side parallel with the milling machine substrate, another component vertically acts on the bottom surface and the milling machine substrate that make compact heap on the milling machine substrate and tightly fits, thereby guarantee the stability of fixture, workpiece process can not shake.
As preferably, the side of described chuck body also is provided with standby screwed hole, in described preparation screwed hole, is provided with standby hold-down bolt.After long-term the use, have between hold-down bolt and screwed hole after wearing and tearing cause becoming flexible and can use standby screwed hole and standby hold-down bolt, thus the service life of improving whole fixture.
Therefore, the utlity model has and can guarantee the just whole workpiece planarization of energy Milling Process of clamped one time, thus the beneficial effect of assurance machining accuracy and crudy.
