Description

Technical Field

[0001] The utility model relates to the technical field of an instrument placement rack, and more specifically to a frame-type spliced ​​machine tool bed. Background Art

[0002] Machine tools are mechanical equipment used to process metal, wood or other materials, and can manufacture parts or products by cutting, forming, drilling, etc. The machine tool bed is one of the key components of the machine tool, and its function is to support and fix the various moving parts and worktables of the machine tool. The bed is usually made of high-strength cast iron or welded structure to ensure the stability and rigidity of the machine tool during operation, thus affecting the processing accuracy and stability.

[0003] China Publication No. CN2312096Y discloses a frame-type spliced ​​machine tool bed, which is composed of two left-side frames [1], two right-side frames [2], one front-end frame [3], and one rear-end frame [4]. The invention is characterized in that the interior of the bed is completely empty. The front-end frame [3] and the rear-end frame [4] both have positioning stoppers [6] of accurate and consistent size, and the connection between the side frames on the AB surface and the connection between the side frames and the end frames on the CD surface are both positioned by taper pins [7] and fastened by bolts [8]. An adjustable anti-vibration pad [5] is installed at the bottom of the bed. The utility model is used for equipment where the actuator needs to operate inside the bed. The utility model has the advantage of expanding the scope of use of the bed, and since the bed is spliced ​​by the unit side frames and the end frames, it is also easy to disassemble and assemble.

[0004] However, the utility model has the following problems when actually used:

[0005] 1. The machine tool bed is only fixed with bolts during splicing. As long as one set of nuts is loose, gaps will easily appear between the corresponding positions of each set of frames of the machine tool, resulting in a decrease in the overall strength and bearing capacity of the device, and even affecting the normal operation of the equipment installed on the device;

[0006] 2. The supporting legs of each set of machine tool bed frames lack fixity to each other. When the equipment vibrates during operation, each set of frames can easily become loose and separate, and the integrity of the device is weak. Utility Model Content

[0007] In order to overcome the above-mentioned defects of the prior art, the utility model provides a frame-type spliced ​​machine tool bed to solve the problems existing in the above-mentioned background technology.

[0008] The utility model provides the following technical solution: a frame-type splicing machine tool bed, comprising:

[0009] A machine tool frame, wherein the machine tool frame is provided with multiple groups, and the multiple groups of the machine tool frames are sequentially distributed in a linear array manner, and support rods are fixed at the four corners of the bottom end of the machine tool frame;

[0012] Preferably, the triangular merging blocks are provided in multiple groups, and the multiple groups of triangular merging blocks are symmetrically and mirror-imagedly distributed at the four corners of the upper surface and the lower surface of the machine tool frame. One side of the triangular merging blocks is arranged as a slope facing the center line of the machine tool frame, and the surface of the slope is smooth and free of burrs, so that the four corners can be fixed during the splicing of each group of machine tool frames, thereby enhancing the firmness of the device.

[0013] Preferably, the fastening blocks are provided in multiple groups, and each two groups of the fastening blocks are symmetrically distributed at one end of the connection between each two groups of the machine tool frames. An isosceles trapezoidal groove is opened in the middle of the bottom end of the fastening block, and the inclined surfaces on both sides of the isosceles trapezoidal groove are matched with the inclined surface on one side of the triangular merging block. When the fastening block is inserted into the outer surface of the triangular merging block, a certain amount of frictional resistance can be reduced, and at the same time, as the fastening block is inserted, the two adjacent groups of triangular merging blocks can gradually move closer.

[0014] Preferably, the long screws are provided in multiple groups, and the multiple groups of long screws are symmetrically distributed on both sides of each group of the fastening blocks. One end of the long screws simultaneously slides through one side of the two corresponding groups of the fastening blocks, so that the fixation between each two corresponding groups is stronger.

[0015] Preferably, the base plates are provided in multiple groups, and every two groups of base plates are symmetrically and mirror-image-distributed at the bottom ends of every two groups of support rods, so as to facilitate supporting the device and facilitating the engagement between every two groups of base plates.

[0016] Preferably, the channel grooves and the short studs are provided in multiple groups of the same number, and the multiple groups of channel grooves and the short studs are equidistantly distributed in a linear array. Each group of channel grooves corresponds to each group of short studs, which makes it convenient for workers to place the short studs into the slots and also provides space for tightening the push nut.

[0017] Preferably, one end of each two adjacent groups of base plates are engaged and connected with each other, and each two groups of slots are connected, providing placement space for short studs, push nuts and anti-slip pads.

[0018] Preferably, the push nuts and the anti-slip pads are provided in multiple groups, and the number of the multiple groups of push nuts and the anti-slip pads is equal to twice the number of the short studs, one side of the anti-slip pads of one group is tightly against the inner wall side of one group of base plates, and one side of the anti-slip pads of another group is tightly against the inner wall side of the other group of base plates, so that the anti-slip pads are tightly against the inner wall of the base plate, so that the two groups of base plates are not easily loosened.

[0019] The technical effects and advantages of the utility model are as follows: the utility model makes the connection between each group of machine tool frames more closely by sliding the fastening block on the outer surfaces of two adjacent groups of triangular merging blocks, and uses a long screw and an anti-dropping nut to fix each two groups of corresponding fastening blocks, so that it is not easy to have a gap in the middle, and effectively reduces the occurrence of gaps between each group of machine tool frames due to the loosening of one group of anti-dropping nuts, so that the device is more stable when used, improves the overall strength and load-bearing capacity of the device, and ensures the stability and accuracy of the movement of other components installed on the device;

[0020] By snapping two adjacent groups of base plates together and then rotating the push nut to make the anti-skid pad press against the inner wall of the base plate, the two adjacent groups of base plates are not easily separated, ensuring that the device can act as a whole. When the equipment vibrates during operation, each group of machine tool frames will not easily separate, further enhancing the stability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
