Embodiment 1

[0010] Example 1. according to figure 1 As shown, 1 is the foundation, 2 and 11 are two bases with the same structure, and 5 and 6 are two gantry frames with the same structure. Through the rack mating gear mechanism 12 meshing with the rack 4, the gantry frames 5 and 6 perform reciprocating linear motion on the linear guide rail 3. Both the linear guide rail 3 and the rack 4 are fixed on the bases 2 and 11. The bases 2 and 11 and the workbench 10 are all fixed on the foundation 1. 5 and 6 two gantry frames all have four drilling and milling head mechanisms 7 with the same structure. Drilling and milling head mechanism 7 and drilling and milling head mechanism 17 all can be loaded onto press tool table turning machine parts. Gantry 5 and 6, the lifting guide of its square beam 18 and drilling and milling head mechanism 17 is to adopt cylinder and cylinder sliding sleeve to cooperate. 8 and 9 are two rotary table mechanisms with the same structure. 10 is an extended workb...

Embodiment 2

[0011] Example 2. Said gantry frame 5 in embodiment 1, as figure 1 Shown, the portal frame 5 both sides are respectively provided with two vertical round columns 13. Reducer 14 drives leading screw 15, and leading screw 15 cooperates with double-hole cover 16, thereby makes double-hole cover 16 do linear motion up and down along round column 13. The drilling and milling head mechanism 17 is connected with the double hole sleeve 16, so that the drilling and milling head mechanism 17 moves vertically up and down. The lead screw 20 cooperates with the bottom plate 22 of the vertical knife sliding sleeve, the drilling and milling head mechanism 7 is connected with the bottom plate 22 of the vertical knife sliding sleeve, the upper and lower two linear guide rails 21 are fixed on the square beam 18, and the beam screw reducer 19 is fixed on the square beam 18 On the left and right sides, the beam lead screw reducer 19 drives the lead screw 20, so that the drilling and milling hea...

Embodiment 3

[0012] Example 3. Said rotary table mechanism 8 in embodiment 1, as figure 2 and image 3 As shown, the main reducer 29 is fixed on the side wall of the base 33, the frequency conversion motor 28 drives the main reducer 29, the main reducer 29 transmits the speed and torque to the ring gear 30, and the ring gear 30 is fixed on the workbench 32, The main shaft 34 is connected with the workbench 32, and the upper and lower parts of the large slewing bearing 31 are respectively fixed on the base 33 and the workbench 32. Therefore, the ring gear 30 transmits the rotational speed and torque to the worktable 32, and the worktable rotates at a certain rotational speed. When the workbench needs indexing, the main reducer 29 is driven to the highest gear, the frequency conversion speed regulation motor 28 stops, the indexing reducer 36 drives the indexing gear 35 to rotate, and the indexing gear 35 drives the ring gear 30 to rotate. Thus, the workbench is indexed, and the accuracy ...

Abstract

A gantry-movable drilling, boring and milling compound machine tool is guided by matching of typical cylinders and cylindrical sliding sleeves and adopts a stepless variable frequency speed regulation mechanism and a numerical control mode. Large-scale swing bearings are adopted for support and rotation of workbenches. In the material aspect, vertical column guide rails and cylindrical movable cutters are manufactured by structural alloy steel thick-walled seamless pipes and are subjected to grinding and hard chromium plating, and the workbenches are casted by ductile cast iron. The gantry movable drilling, boring and milling compound machine tool has the advantages that the machine tool can be used for drilling and boring and has functions of excircle, inner bore, section and curved surface turning, flat surface, inclined surface, curved surface and groove milling, thread tapping and the like, lubrication, dust prevention and durability of the guide rails are guaranteed, and long-term precision is maintained. Double gantries are movable, work efficiency can be improved by machining long and large pieces by the juxtaposed double gantries together, the large-scale rotating workbenches additionally arranged at two ends can be used as two numerical control lathes, equipment utilization rate is increased, and the gantry-movable drilling, boring and milling compound machine tool is simple in structure and can meet customer machining requirements particularly when parts are large in machining face and machining length.

Description

technical field [0001] The invention relates to a gantry mobile drilling, boring and milling compound processing machine tool, which is applied to the processing of mechanical parts. Background technique [0002] At present, the known drilling, boring and milling machines generally adopt T-shaped grooves, dovetail grooves or square grooves as guides, and slide blocks and ram mechanisms cooperate. The speed regulating mechanism is mechanically variable, the control is manual control and general electrical control, the workbench is a plane guide rail structure, the lubrication structure is hydraulic pump circulation lubrication, and the gantry cannot move. This type of machine tool cannot ensure the lubrication, dustproof and durability of the guide rail and maintain the long-term accuracy. Contents of the invention [0003] In order to overcome the structural defects of traditional drilling, boring and milling machines, the present invention provides a novel and uniquely s...
