Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0015] See Figure 1A T-shaped horizontal machining center with double exchange worktables includes a bed 1 and a column 2. The bed 1 has a T-shaped structure, and the transverse part of the bed is slidably connected to the column 2 via a slide rail assembly and a lead screw assembly. The front of the column 2 is slidably connected to a slide saddle 3 via a slide rail assembly and a lead screw assembly. A spindle box 4 is mounted on the slide saddle 3. A slide rail assembly and a lead screw assembly are mounted on the longitudinal part of the bed 1. A rotary table 5 is mounted on the slider of the slide rail assembly, and the lead screw assembly is threadedly connected to the rotary table 5. An exchange base 6 is mounted at the front end of the bed 1. A rotary lift 7 and a positioning tray 8 are mounted on the exchange base 6. A U-shaped support fork 9 is mounted on the output shaft of the rotary lift 7. U-shaped grooves are opened on the left and right sides of the U-shaped support fork 9 to support the worktable 10. The worktable 10 cooperates with the rotary table 5 and the positioning tray 8 respectively. Specifically, in the actual processing, when the worktable 10 needs to be replaced, the worktable 10 located on the positioning tray 8 is in a standby state. The rotary lift 7 starts to rise and lifts the worktable 10 through the U-shaped support fork 9. After being lifted, it is rotated to rotate the worktable 10 to the rotary table 5. Then the worktable 10 is lowered so that the worktable 10 docks with the rotary table 5. After docking, the worktable 10 separates from the U-shaped support fork 9, and the rotary table 5 moves to below the spindle box 4 under the action of the lead screw assembly and slide rail assembly, thereby realizing the cutting process. During the cutting process, the positioning tray 8 is freed up and is in a standby state, and the worktable 10 can be loaded and unloaded, thereby saving time and improving work efficiency. The rotary table 5 and the rotary lift 7 are both existing technologies and will not be described in detail in this application. The rotary lift 7 used in this application is model GHA630HT.

[0016] To improve control precision, all lead screw assemblies are driven by servo motors.

[0017] See Figure 1 The horizontal part of the bed frame 1 has a sloping structure, and the slide rail assembly is set on two surfaces, one high and one low. At the same time, the bottom of the upright 3 also has a structure with one high and one low, which transfers the weight of the upright 3 to the rear side. Combined with the sloping structure of the bed frame 1, it increases the load-bearing capacity of the bed frame and improves its stability.

[0018] To improve machining accuracy, a grating ruler 11 is installed on the inclined surface to assist the servo motor in high-precision movement.

[0019] See Figure 3-4 Positioning cones 12 are respectively provided on the upper surfaces of the rotary table 5 and the positioning tray 8, and positioning posts 13 are provided on the bottom of the worktable 10. The positioning posts 13 and the positioning cones 12 cooperate with each other. In order to improve the stability of the connection between the rotary table 5 and the worktable 10, and between the positioning tray 8 and the worktable 10, the positioning cones 12 and the positioning posts 13 cooperate with each other, and the positioning posts 13 are embedded in the positioning cones 12 for matching.

[0020] See Figure 5The U-shaped support fork 9 includes a central force-applying part 91 and U-shaped parts 92 on the left and right sides. The force-applying part 91 is provided with reinforcing ribs 93, and the periphery of the U-shaped parts 92 is provided with anti-collision rubber blocks 94. The force-applying part 91 is fixedly connected to the output shaft of the rotary lift 7. The U-shaped parts 92 have U-shaped grooves to support the worktable 10 and rotate and lift under the action of the rotary lift 7. The reinforcing ribs 93 are used to increase the overall strength of the U-shaped support fork 9. The anti-collision rubber blocks 94 are used to support the worktable 10 and prevent damage between the worktable 10 and the U-shaped support fork 9.

[0021] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
