Problems solved by technology
[0002] At present, the drilling process of the side frame of the cast steel bogie of the three major trucks is generally adopted: the holes in the central frame of the side frame are processed by a special drilling machine, the side frame is placed vertically or horizontally for clamping; the stoppers at both ends of the side frame The key holes are processed by a general-purpose radial drilling machine, and the side frame is placed vertically for clamping; therefore, the drilling process requires two sets of equipment and two processes to complete, resulting in low production efficiency and high processing costs

Embodiment Construction
[0010] Below in conjunction with embodiment the present invention is further described.
[0011] see figure 1 , 2 , a special drilling machine tool for truck side frames, including a base 6, a side frame positioning seat 7, a clamping bracket 5, a column drilling head 4 and a column drilling head guide rail 3; one side of the base 6 is provided with two symmetrical stops Key drilling head 2 and block key drilling head guide rail 1.
[0012] It adopts the combination drill box type, and the outline layout is a three-frame structure, which is composed of three drilling head boxes.
[0013] The column drilling head guide rail 3 and the column drilling head 4 form the central box drilling equipment; the key drilling head guide rail 1 and the key drilling head 2 form the key drilling equipment; the central box drilling uses a drilling machine Head box, one drilling head box for each of the two key drilling; each drilling head box has an independent guide rail, the two key drilli...

The invention discloses a drilling machine tool dedicated for a truck side frame, belonging to the technical field of railway truck machining. The drilling machine tool comprises a substrate, a side frame locating base, a clamping bracket, a stand column drilling head and a stand column drilling head guide rail, wherein one side of the substrate is provided with two symmetrical stop key drilling heads and stop key drilling head guide rails. According to the drilling machine tool, machining working procedures are reduced, equipment amount is reduced, and production cost is lowered; stop key drilling quality is improved; times for hoisting and clamping are reduced, manpower amount is reduced, worker labor intensity is lightened, and manpower cost is lowered; working procedures and product amounts are reduced, the flat area of the machining technology is reduced, the product working procedure cycle is shortened, and production efficiency is improved; and the drilling machine tool is used for machining the truck bogie side frame of 70 tons and above.
Description
Technical field [0001] The invention relates to railway freight car manufacturing equipment, in particular to side frame machining equipment, and belongs to the technical field of railway freight car machining. Background technique [0002] At present, the drilling process of the side frame of the cast steel bogie of the three major trucks is generally adopted: the holes in the central frame of the side frame are processed by a special drilling machine, the side frame is placed vertically or horizontally for clamping; the stoppers at both ends of the side frame The key holes are processed by a general-purpose radial drilling machine, and the side frame is placed vertically for clamping; therefore, the drilling process requires two sets of equipment and two processes to complete, resulting in low production efficiency and high processing costs. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing side frame drilling proces...
