Long-travel spliced bed adopting glue-filled connecting structure and splicing method

Abstract

The invention discloses a long-travel spliced bed adopting a glue-filled connecting structure and a splicing method. The spliced bed comprises at least two sections of beds, the beds are positioned by adopting hinged bolts, spliced by the glue-filled connecting structure at the joint and then fastened by fastening bolts, each section of bed integrally adopts a welded structure, and thereby the overall weight, machining difficulty and transportation difficulty of the bed are decreased. Inclined rib plates and sidewall plates of the bed form an equilateral triangle-shaped stable structure, and in combination with transverse rib plates, the equilateral triangle-shaped stable structure ensures that the bed has good static characteristics; since the junction surfaces of the two adjacent beds adopt the glue-filled connecting structure, the contact area of the junction surfaces is enlarged, the overall dynamic characteristic of the bed is improved, the requirement on the perpendicularity between the outer sides of two end plates and a track is decreased, and thereby machining difficulty is decreased and assembly precision is ensured. The bed is a spliced bed structure which is mainly used in a fixed beam and movable pillar type aluminium material gantry machining center and ensures the rigidity and assembly precision of a bed.

Description

technical field [0001] The invention relates to a long-stroke splicing bed and a splicing method using a glue-filled connection structure, especially a new splicing bed structure and a splicing method for a fixed-beam moving-column aluminum gantry machining center to ensure the rigidity and assembly accuracy of the bed , belongs to the technical field of aluminum material processing equipment. Background technique [0002] The milling of various holes and grooves of aluminum components such as building curtain walls, guide rail transportation, and ships generally uses fixed-beam and moving-column gantry machining centers. Due to the different sizes of workpieces, the X-direction travel of the machining center is also different. Usually, the X-direction The stroke is between 6 and 25m, and the length of the X-direction bed is between 7 and 30m. The bed of the machining center adopts a welded structure, but due to the constraints of steel plate length, processing equipment, d...

Problems solved by technology

[0004] In order to overcome the disadvantages of the existing splicing bed, which is difficult to process and has poor dynamic characteristics, the present invention provides a long-stroke splicing bed and a splicing method using a glue-filled connection structure. The splicing bed uses a welding machine with good rigidity. The structure is designed to achieve lightweight design, and the glue-filled connection structure is used at the segmental splicing, which reduces the verticality requirements of the end faces of each segment and the guide rail surface, and improves the dynamic characteristics of the joint surface
