Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool accessories, in particular to a slotted cast iron platform. Background Art

[0002] The cast iron platform is a workbench, which is mainly used in the fields of mechanical processing, inspection, measurement and workpiece detection. Slotting can increase the area and stability of the platform. By adding several notches on the surface of the cast iron platform, the platform can be made more stable and less prone to deformation. At the same time, due to the increase of notches, the area of ​​the platform can also be increased accordingly, making it easier to inspect and mark the workpiece. Secondly, adding grooves can also facilitate inspection and marking work.

[0003] The utility model patent with patent application publication number 202021594714.7 discloses a cast iron platform with good flatness, including a cast iron bracket, a working platform and an adjustment component. The working platform is movably installed on the top of the cast iron bracket, and the adjustment component is installed in the cast iron bracket and is detachably connected to the bottom of the working platform. The adjustment component includes a bottom support plate, a driving cylinder and an upper fixed plate. The bottom support plate is fixed to the bottom of the driving cylinder and can contact the ground. The upper fixed plate is fixed to the end of the piston rod in the driving cylinder. Fixing screws are installed on both sides of the upper fixed plate. The fixing screws are threaded to connect and fix the upper fixed plate to the working platform. A limiting component is installed between the working platform and the cast iron bracket. The utility model is provided with an adjustment component, so that the height of the working platform can be adjusted according to the needs of the user, which does not affect the use of the platform and its flatness, and relatively reduces the trouble of affecting the workpiece processing due to the low platform, and the entire component is easy to disassemble.

[0004] According to the above device, during the installation process of the existing cast iron platform, multiple sets of bolts are usually used to fix the cast iron platform. When the cast iron platform needs to be repaired, inspected or replaced, it is necessary to turn multiple sets of bolts to disassemble the cast iron platform, which is inconvenient for disassembly and assembly of the cast iron platform and increases the labor intensity of the staff. For this reason, we propose a slotted cast iron platform. Utility Model Content

[0005] The purpose of the utility model is to provide a slotted cast iron platform to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0008] The four corners of the top of the mounting platform are each provided with a fixing groove, a limiting groove is provided on the side close to the fixing groove, and supporting grooves are provided on the two sides away from the mounting platform. The inner cavity of the limiting groove is slidably connected to the limiting rod, the inner cavity of the supporting groove is slidably connected to the trapezoidal block, and the inclined surface of the trapezoidal block is provided with a guide groove for connecting the limiting rod.

[0009] As a preferred technical solution of the present application, the lifting mechanism includes a bidirectional screw, two groups of threaded blocks and two groups of fixed blocks. A slide groove is provided on the top of the support platform. The bidirectional screw is rotatably connected to the inner cavity of the slide groove. The threaded blocks are threadedly connected to the outer walls of the bidirectional screw. The fixed blocks are fixedly connected to the bottom sides of the mounting platform. A transmission part is provided at the bottom of the fixed block.

[0010] As a preferred technical solution of the present application, the transmission member includes a transmission rod, which is rotatably connected to the bottom of the fixed block through a rotating shaft and is rotatably connected to the threaded block, and the threaded block is slidably connected to the inner cavity of the slide groove.

[0011] As a preferred technical solution of the present application, telescopic rods are fixedly provided at the four corners of the top of the support platform, and the connecting ends of the telescopic rods are fixedly connected to the bottom of the mounting platform.

[0012] As a preferred technical solution of the present application, a slope is provided on one side of the limit rod close to the trapezoidal block, and the limit rod slides on the guide groove through a slider.

[0013] As a preferred technical solution of the present application, a base is fixedly provided on the side of the bottom of the cast iron table corresponding to the fixing groove, and a positioning groove matching the limiting rod is provided on the side close to the base.

[0014] As a preferred technical solution of the present application, one end of the bidirectional screw is fixedly connected to a turntable, and the side of the trapezoidal block away from each other is fixedly connected to a pull plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] In the scheme of this application:

[0017] 1. By setting trapezoidal blocks and limit rods, the base of the cast iron table is limited in the fixed groove by the limit rod cooperating with the limit groove and the positioning groove. By pulling the pull plate, the pull plate slides in the support groove. Since the pull plate and the limit rod realize inclined sliding through the guide groove, the pull plate can drive the limit rod to move relatively horizontally when it moves. At this time, the limit rod slides in the limit groove and moves out of the positioning groove, so that the base of the cast iron table loses its limit and can be disassembled, thereby facilitating the disassembly and assembly of the cast iron platform and reducing the labor intensity of the staff.

[0018] 2. The bidirectional screw is driven to rotate by rotating the turntable, and the bidirectional screw drives the threaded block to slide relatively in the slide groove, and the transmission rod is driven to move and rotate by the threaded block. Since the length of the transmission rod remains unchanged, the threaded block can lift the height of the fixed block and the mounting platform through the transmission rod when it moves, and the cast iron table can be driven to rise and fall through the mounting platform, so as to facilitate the adjustment of the height of the cast iron platform.
