It will be appreciated by those skilled in the art that features from the examples and embodiments described below may be combined with each other without conflict.
Referring to fig. 1 to 5, a numerical control planomiller capable of processing a very long part includes a machine tool guide rail, a gantry 1 capable of moving linearly along the machine tool guide rail, a miller head 11 mounted on the gantry, and a machine tool base 12 penetrating through the gantry, wherein the miller head 11 can move horizontally and vertically. The basic structure of the numerical control planer type milling machine can refer to the prior art.
In order to realize the processing of the overlong part 5, the numerical control planer type milling machine is modified. Both ends of machine tool base 12 all are connected with extension base 2, the last surface mounting of extension base 2 has workstation guide rail 21 and can follow the mobile workbench 22 that workstation guide rail 21 removed, and the both ends of waiting to process overlength part 5 are the clamping respectively on the mobile workbench 22 at both ends, be equipped with the bed hedgehopping block group spare 23 that supports waiting to process overlength part 5 on the mobile workbench 23.
Because the overlong part 5 is clamped on the movable workbench 22, after the part of the overlong part 5 positioned in the machining range boundary of the numerical control planer type milling machine is machined, the part originally positioned outside the machining range boundary of the numerical control planer type milling machine can enter the machining range boundary of the numerical control planer type milling machine in a mode of moving the movable workbench 22, and thus the machining of the unprocessed part can be completed. Therefore, the processing capacity and the utilization rate of the equipment are improved, and the processing cost is reduced.
In addition, as the whole machining process only has one-time clamping, the machining is continued after the movable worktable moves in the middle process without measuring and adjusting again. Through testing, the efficiency of processing is improved by more than 45% -60% compared with the traditional splicing processing mode, the clamping is convenient, the clamping is safe and reliable, the precision is high, the error of repeated clamping, the error of processing and the error of measurement do not exist, and the size precision error can be controlled within 0.02 mm.
For the machining range of the machine tool after transformation, the length of the machine tool base 12 is L0, the moving lengths of the movable tables 22 on the lengthened base on the two sides of the length of the machine tool base, which can move along the guide rails of the tables, are L1 and L2 respectively, the length of the ultra-long part 5 to be machined is X, and L0+ L1+ L2 is more than or equal to X.

This part of the structure can be referred to in the prior art, for example, the locking screw is used for the worktable locking assembly, which can ensure the locking of the linear sliding block 221 and the worktable rail 21.
In order to further ensure the locking reliability of the movable workbench 22, a locking block 25 which can be fixed with the lengthened base 2 is connected to the end part of the movable workbench 22. The locking block 25 includes an upper horizontal portion, a vertical portion and a lower horizontal portion, which are connected in sequence to form a Z-shaped structure.

The lengthened base 2 is provided with locking threaded holes at intervals along the length direction, the lower horizontal part is provided with a kidney-shaped groove, the kidney-shaped groove is connected with a locking screw, and the locking screw is connected with the locking threaded holes. After the movable worktable 22 moves to the set position, the reliability of the locking of the movable worktable 22 is ensured through the double locking of the worktable locking assembly 222 and the locking block 25.
In the present embodiment, the two extension bases 2 on both sides of the length of the machine tool base 12 are equal in length, and the table rail 21 on the extension base 2 is also equal in length, that is, L1 is L2. Of course, it will be understood that this may not be the case.
For clamping of an overlong part to be machined, the overlong part is long in length and vibrates greatly in the working process, so that reliable clamping of the end part needs to be guaranteed.
