The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

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 numerically controlled planer type milling machine for processing ultra-long parts includes a machine tool guide, a gantry 1 linearly movable along the machine tool guide, a milling machine head 11 mounted on the gantry, and a machine tool base 12 penetrating through the gantry, wherein the milling machine 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.

Therefore, the linear slider 221 is connected with a table locking assembly 222 which can be locked and fixed with the table rail 21. 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.
