Abstract

The utility model relates to a high-precision numerically-controlled machine tool milling jig comprising a positioning rack fixedly connected with a work bench, wherein the lower surface of a positioning plate in a suspending shape on the upper portion of the positioning rack is a positioning datum plane, the lower side of the positioning plate is provided with a supporting mechanism, and a to-be-processed component is placed between the supporting mechanism and the positioning datum plane. The utility model applies the lower surface of the positioning plate as the positioning datum plane, tightly props a to-be-processed component through the supporting mechanism, enables the to-be-processed face of the to-be-processed component to tightly cling to the lower surface of the positioning plate, and avoids the positioning error caused by the form tolerance of the to-be-processed component itself. The high-precision numerically-controlled machine tool milling jig has accurate positioning, and is convenient for processing to-be-processed components simultaneously.

Description

The high-precision numerical control machine milling clamper

Technical field

The utility model relates to a kind of high-precision numerical control machine milling clamper.

Background technology

Generally speaking, when the similar parts to be processed of processing square thin-walled overlength parts etc.,, run into the problem of clamping difficulty through regular meeting because the length of parts to be processed itself is longer.For this square thin-walled overlength parts, usually with the working face of workbench datum level as the location, because parts to be processed itself have form tolerance, when needs on parts to be processed during working groove, be difficult to guarantee the machining accuracy of many group grooves, in case go wrong after the processing, also be difficult to remedy.

The utility model content

The purpose of this utility model is to provide a kind of high-precision numerical control machine milling clamper, and these anchor clamps can either guarantee accurate positioning, simultaneously also be convenient to treat processing component processes.

For achieving the above object, a kind of high-precision numerical control machine milling clamper that the utility model provides, comprise the locating rack that is connected with stationary table, the lower surface of the location-plate of the shape that suspends on locating rack top is the location datum level, the below of location-plate is provided with supporting mechanism, places parts to be processed between this supporting mechanism and the location datum level.

The utility model with the lower surface of location-plate as the location datum level, hold out against parts to be processed by supporting mechanism, make to be processed of parts to be processed to fit tightly, avoided because the position error that form tolerance caused of parts to be processed itself with location-plate lower surface as the location datum level.The utility model accurate positioning is convenient to treat processing component simultaneously and is processed.

Fig. 2 is the structural representation after the utility model is put into parts to be processed;

Fig. 3 is the structural representation after the component processing to be processed in the utility model;

Fig. 4 is the vertical view of Fig. 3.

The specific embodiment

For convenience of explanation, the utility model is to be described with the embodiment that Fig. 1,2 provides, and wherein, cutter 10 is positioned at the top, and workbench 50 is positioned at the below of cutter 10, and cutter 10 can be walked in the horizontal direction, vertical direction feed up and down.

A kind of high-precision numerical control machine milling clamper, workbench 50 upwards is provided with locating rack 20, it is Z-shaped or I-shaped that the shape of locating rack 20 roughly is, the lower surface of the location-plate 21 of the shape that suspends on locating rack 20 tops is location datum level 22, the below of location-plate 21 is provided with supporting mechanism 30, place parts 40 to be processed between this supporting mechanism 30 and the location datum level 22, to be processed and 22 applyings of location datum level of parts 40 to be processed, offer the technology through hole 23 that can supply cutter 10 to pass and walk on the location-plate 21, location-plate 21 and locating rack 20 are connected and fixed by bolt, as Fig. 1, shown in 2, cutter 10 passes through hole 23 on the location-plate 21 and treats processing component 40 and carry out machining.Because parts to be processed 40 itself are very long, be generally 5～6 meters long, therefore, locating rack 20 can be made one group of a plurality of composition and treat processing component 40 clampings, and the length of one group of locating rack 20 is consistent with the length of parts 40 to be processed, is convenient to treat processing component 40 and carries out clamping.

In conjunction with Fig. 1,2,3,4, the length L of similar elongated pipes such as square thin-walled overlength parts is longer, there is form tolerance body in itself, when the upper surface working groove 41 of parts 40 to be processed, if the working face that adopts workbench 50 is as datum level, then can't overcome the position error that form tolerance itself that had by parts 40 to be processed is brought, the groove depth H that is processed is also not of uniform size, must adopt the manual size of repairing after the processing.The utility model as location datum level 22, has overcome position error with the lower surface of location-plate 21, thereby improves and guaranteed machining accuracy, guarantees that the size of groove depth H is consistent.

Below in conjunction with Fig. 1,2,3,4, the utility model is further described.

Described supporting mechanism 30 be comprise first and

second slide block

31,32 tiltedly carve mechanism, be positioned at below first slide block 31 on the workbench 50 and also can slide along its working face, the following applying of top and second slide block 32 of first slide block 31, angle α is arranged between the table top of this binding face and

workbench

50,10 °＜α＜30 °, the parts top and to be processed 40 of second slide block 32 are fitted.In other words, supporting mechanism 30 adopts tiltedly carves mechanism, this is tiltedly carved mechanism and comprises first and

second slide block

31,32, first slide block 31 is positioned on the workbench 50 and can slides along its working face, first slide block 31 upwards is provided with second slide block 32 that cooperates with its formation slippage, the two relative inclined-plane coincide each other, and second slide block 32 is fitted with parts 40 to be processed.

Fixedly install L-shaped support 33 on the described workbench 50, offering on the riser of support 33 can be for the screwed hole of bolt 34 connections, bolt 34 passes screwed hole and screws in first slide block 31, and described riser is meant plate body vertical with the table top of workbench 50 on the support 33.When tighting a bolt 34 the time, support 33 will screw power and be passed to first slide block 31, along with bolt 34 screws in first slide block, 31 inside, first slide block 31 along the working face level of workbench 50 to left movement, simultaneously, second slide block 32 is because the effect of first slide block 31 upwards holds out against parts 40 to be processed, cutter 10 feeds subsequently, cutter 10 is treated processing component 40 according to the trend of the through hole of offering 23 on the location-plate 21 and is processed, after the processing, form groove 41 on the outer wall of parts 40 to be processed, its shape is identical with the shape of through hole 23, is a pair of right " eight " word shape, the shape of groove 41 can be according to the needs adjustment of processing, the depth H of groove 41 is determined that by the depth of cut tolerance value that groove depth H allows is ± 0.01mm to process after one group of groove 41, unscrew bolt 34, with parts 40 to be processed translation in cutter 10, finish processing, by that analogy to next group groove 41.

In sum, core of the present utility model is to be provided with location-plate 21 on workbench, with the lower surface of location-plate 21 as location datum level 22, to be processed of parts 40 to be processed directly fit with location datum level 22, cutter 10 is directly treated processing component 40 through location datum levels 22 and is implemented processing, and this anchor clamps have been avoided the position error brought because of the form tolerances of parts to be processed 40 itself, accurate positioning, thereby raising has also been guaranteed machining accuracy, is convenient to clamping simultaneously.
