However, the bed structure of a traditional vertical machining center is fixed and single, and the placement position of the vertical machining center is not necessarily in a horizontal state. The bed itself does not have a leveling function. When the bed is placed on a slightly tilted ground position, it will cause the overall deviation and tilt of the worktable and the columns, which is not conducive to the parts processing workers to perform workpiece processing operations.

[0023] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0024] like Figure 1-Figure 7 As shown, the utility model provides a bed structure of a vertical machining center, including a column seat 14; the lower side of the column seat 14 is welded and connected to a bed body 1, and the front and rear sides of the bed body 1 are both bonded with transverse leveling liquid tubes 13; it also includes a lower bed seat 2, a longitudinal leveling liquid tube 8 and an adjusting rod 11; the outer side of the lower bed seat 2 is welded and connected to a support seat 3, the upper side of the support seat 3 is equipped with a shock-absorbing spring 7, the upper side of the shock-absorbing spring 7 is equipped with a fixing plate 4, the lower side of the fixing plate 4 is welded and connected to a movable rod 12, the bottom end of the movable rod 12 is welded and connected to a foot seat 6, and the lower side of the foot seat 6 is bonded with a rubber gasket 5; the outer side of the adjusting rod 11 is meshed and connected to a rotating sleeve 10, the outer side of the rotating sleeve 10 is meshed and connected to a clamping nut 15, and the top of the adjusting rod 11 is welded and connected to a top ball 9; the number of longitudinal leveling liquid tubes 8 is two groups, and the longitudinal leveling liquid tubes 8 are bonded to the left and right sides of the bed body 1.

[0025] When the utility model is performing the leveling work of the bed of the vertical machining center, the processing personnel first clamps the wrench on the outer side of the clamping nut 15, and then manually twists the clamping nut 15 with the wrench. Since the clamping nut 15 is screwed on the threaded surface of the outer side of the rotating sleeve 10 through a thread, the clamping nut 15 rotates downward along the threaded path of the outer side of the rotating sleeve 10, so that the clamping nut 15 and the hexagonal column structure on the outer side of the rotating sleeve 10 are loosened from the lower side of the groove of the lower bed seat 2, so that the rotating sleeve 10 can rotate in the large through hole inside the groove of the lower bed seat 2. Then the processing personnel twists the hexagonal column structure of the rotating sleeve 10 with a wrench. Since the threaded engagement of the outer side of the adjusting rod 11 is connected to the threaded mechanism on the inner side of the cylinder of the rotating sleeve 10, the rotating sleeve 10 drives the convex strip of the adjusting rod 11 along the groove structure of the small through hole of the lower bed seat 2 during the rotation process, so that the adjusting rod 11 moves vertically and directionally up and down. The top ball 9 welded to the top of 11 respectively fits the hemispherical structure of the bottom of the four groups of hole grooves on the lower side of the bed 1. When the adjusting rod 11 moves up and down, the four corners of the bed 1 are tilted. During the adjustment process, the processing personnel always observe the position of the bubbles in the longitudinal level liquid tube 8 and the transverse level liquid tube 13. When the bubbles in the longitudinal level liquid tube 8 and the transverse level liquid tube 13 are in the middle position, the correction and leveling work of the bed of the vertical machining center is completed. Then the processing personnel holds a wrench in one hand and clamps it on the six-sided column structure of the rotating sleeve 10 to keep the rotating sleeve 10 fixed. The processing personnel places the wrench on the clamping nut 15 with the other hand and manually twists the clamping nut 15 so that the clamping nut 15 cooperates with the six-sided column structure of the rotating sleeve 10 to clamp the rotating sleeve 10 on the lower bed seat 2 to prevent the rotating sleeve 10 from rotating due to the vibration of parts processing and affecting the horizontal state of the bed 1.

[0026] In the disclosed embodiment, there are four groups of rotating sleeves 10, and each group of rotating sleeves 10 is a cylindrical structure with an opening on the upper side. The inner side surface of the cylindrical structure of the rotating sleeve 10 is provided with a threaded structure, and the outer side surface of the rotating sleeve 10 is provided with a hexagonal column structure and a threaded structure from top to bottom. The parts processing personnel can use a wrench to twist the rotating sleeve 10 at the hexagonal column structure of the rotating sleeve 10 to rotate, so that the rotating sleeve 10 drives the adjusting rod 11 to adjust the height, and the leveling operation is simple and convenient. The clamping nut 15 is engaged and connected to the threaded structure on the outer side of the rotating sleeve 10, so that the clamping nut 15 cooperates with the hexagonal column structure to tighten the rotating sleeve 10 to prevent the rotating sleeve 10 from rotating slightly due to vibration.

[0027] In the disclosed embodiment, two groups of grooves are provided on the left and right sides of the lower bed base 2, and small through holes and large through holes are provided on the inner upper and lower sides of the grooves respectively. A groove with upper and lower openings is provided on the inner side of the small through hole of the lower bed base 2, and the bottom end of the rotating sleeve 10 is rotatably connected to the large through hole of the lower bed base 2, so that the leveling mechanism composed of the rotating sleeve 10 and the adjusting rod 11 is arranged in the groove of the lower bed base 2, with a compact structure and a reasonable spatial layout.

[0028] In the disclosed embodiment, there are four groups of adjusting rods 11, and the outer side surface of each group of adjusting rods 11 is provided with convex strips and threaded surfaces in sequence from top to bottom. The threaded surfaces of the four groups of adjusting rods 11 are respectively meshed and connected to the threaded structures on the inner side of the cylinder of the four groups of rotating sleeves 10, and the convex strips of the adjusting rods 11 are embedded in the grooves on the inner side of the small through holes on the upper side of the inner groove of the lower bed base 2. The four groups of rotating sleeves 10 can drive the four groups of adjusting rods 11 to move vertically up and down along the convex strips through threads, change the length of the adjusting rods 11 extending from the inner side of the rotating sleeves 10, and allow the adjusting rods 11 to be lifted or lowered at the four corners of the bed body 1 to complete the leveling of the bed body 1.

[0029] In the disclosed embodiment, there are eight groups of shock-absorbing springs 7. Every two groups of shock-absorbing springs 7 are symmetrically distributed on the left and right sides and the front and rear sides of the lower bed base 2. The shock-absorbing springs 7 are nested in the outer side of the movable rod 12. Each group of shock-absorbing springs 7 adopts rubber springs. The good elastic buffering properties of the rubber springs and the damping energy absorption characteristics of the rubber are utilized to perform vertical shock absorption and noise isolation between the fixed plate 4 and the support base 3, so that the lower bed base 2 can be placed on the ground more stably.

[0030] In the disclosed embodiment, circular holes are provided at the four corners of the lower side of the bed 1, and the bottom of the circular holes is a hemispherical structure. The inner diameter of the circular hole of the bed 1 is larger than the outer diameter of the adjusting rod 11. The adjusting rod 11 is inserted into the circular hole of the bed 1, and the outer surface of the top ball 9 at the top of the adjusting rod 11 fits in the hemispherical structure of the bottom of the circular hole. Through the sliding structure of the top ball 9 and the hemispherical surface of the bottom of the circular hole, the flexible universal angle leveling movement of the bed 1 is completed.

[0031] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The above-mentioned longitudinal level liquid tube 8, transverse level liquid tube 13, and clamping nut 15 are all common components on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.
