Embodiment 1

[0047] combine Figure 1-Figure 7 , a spliced ​​bed system of a high-rigidity gantry machining center in this embodiment includes a common bed 110 and a spliced ​​bed 120, wherein the common bed 110 can adopt a uniform size, and the spliced ​​bed 120 can adopt different lengths and sizes , using the common bed 110 of the same size and the splicing bed 120 of different sizes can splice the required different lengths of the gantry machining center bed, realize the splicing and use of different length machine tools, reduce the length of the single bed, and benefit Casting and transportation; at the same time, the common bed is used as a common material, which is conducive to stocking and reducing production costs. In this embodiment, the common bed 110 and the splicing bed 120 are connected by connecting screws. Specifically, the joint surfaces of the common bed 110 and the splicing bed 120 in this embodiment are the public installation surface 111 and the splicing surface respec...

Embodiment 2

[0058] A spliced ​​bed system of a high-rigidity gantry machining center in this embodiment has a basic structure as in Embodiment 1. Furthermore, in this embodiment, a sealing groove 122 is provided on the splicing mounting surface 121, and a sealing groove 122 is arranged in the sealing groove 122. The sealing ring can effectively improve the sealing performance of the joint surface, ensure the stability of the joint surface at the splicing joint, and further provide guarantee for the subsequent processing accuracy.

[0059] Such as figure 2 As shown, in this embodiment, both sides of the common bed 110 and the spliced ​​bed 120 in the width direction near the joint are provided with oil retaining grooves 130, and the oil retaining grooves 130 can guide the lubricating oil on the line rails to the bed. It can not only effectively prevent oil and water from penetrating into the joint surface and affect the stability of the joint surface, but also prevent oil and water from p...

Embodiment 3

[0064] The spliced ​​bed system of a high-rigidity gantry machining center in this embodiment has a basic structure as in Embodiment 2. Furthermore, in this embodiment, a plurality of sheet metal plates are arranged on the side wall of the base near the guide rail 300 in the collecting tank 350 The joint surface 360, the sheet metal joint surface 360 ​​is used to connect with the metal protective shell, can wrap the guide rail 300 inside, change the sheet metal joint surface 300 at the bottom of the guide rail 300 to the inside, prevent water seepage and leakage, and improve the water resistance of the machine tool. Improve the user's working surface cleanliness.

[0065] In this embodiment, the bottom of the common bed 110 is provided with a plurality of anchor bolts 103, and the plurality of anchor bolts 103 is more convenient for horizontal adjustment and more stable for support.

[0066] In this embodiment, the side of the bottom of the column support 310 close to the guid...

Abstract

The invention discloses a splicing type bed system of a high-rigidity gantry machining center, and belongs to the technical field of gantry milling machines. The system comprises a public bed and a spliced bed, a motor mounting seat and a bearing mounting seat are arranged on the two sides of the public bed in the length direction, and a connecting shin plate is connected between the motor mounting seat and the bearing mounting seat; the public bed and the spliced bed are connected through connecting screws, key grooves are formed in the corresponding positions of the two side walls of the joint surface of the spliced position of the public bed and the spliced bed, the key grooves extend in the width direction of the bed, and taper key combinations used for adjusting the height position of the spliced bed are connected into the two key grooves. According to the splicing type bed system of the high-rigidity gantry machining center, the rigidity strength of the bed can be improved, and the coplanarity and the assembly precision of guide rail surfaces of the spliced bed can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of gantry milling machines, in particular to a spliced ​​bed system of a high-rigidity gantry machining center. Background technique [0002] In the existing CNC machining technology, the gantry machining center is composed of a column, a beam, a spindle head, a worktable, a saddle, a ram and a bed. As an indispensable part of the milling machine, the main function of the bed is to support the saddle and the table for linear motion. At present, the structural strength of the milling machine bed on the market is not high, and the bearing capacity is poor, which will affect the quality and accuracy of the workpiece. [0003] At present, the length of the bed of the existing large-scale gantry machining center is tens of meters, and the overall casting method is generally used, which makes casting, processing and transportation difficult. Even if the bed of a machine tool over ten meters is spliced, it is dif...
