Description

Technical Field

[0001] The utility model relates to the field of machine tool equipment, in particular to a sliding guide rail unloading device. Background Art

[0002] Machine tools refer to machines used to manufacture machines, also known as machine tools or machine tools, and are usually referred to as machine tools. They are generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. There are many methods for processing mechanical parts in modern machinery manufacturing. In addition to cutting, there are also casting, forging, welding, stamping, and extrusion. However, all parts with high precision requirements and fine surface roughness requirements generally need to be finally processed on machine tools by cutting methods. Machine tools play a major role in the construction of national economic modernization.

[0003] Sliding guide rails are generally used for guiding and supporting in machine tool processing centers. Their accuracy, rigidity and structural form have a direct impact on the processing accuracy and load-bearing capacity of machine tools. In order to ensure that CNC machine tools have high processing accuracy and large load-bearing capacity, the guide rails are required to have high guiding accuracy, sufficient rigidity, good wear resistance and good low-speed motion stability. The existing unloading methods of guide rails include hydraulic unloading, mechanical unloading and pneumatic unloading to unload the guide rails;

[0004] The existing application number is CN201820273017.8, which is a sliding guide rail unloading device for a machine tool machining center. It includes a support plate, and the two sides of the support plate are respectively fixedly connected to a first fixed plate and a second fixed plate. A hydraulic rod is fixedly connected to the middle part of the top of the support plate, and the top of the hydraulic rod is fixedly connected to a connecting plate. The top of the connecting plate is movably connected to a mounting plate, one side of the mounting plate is clamped on the side of the first clamping block, and the side of the mounting plate away from the first clamping block is clamped on the side of the second clamping block. The side of the second clamping block away from the mounting plate is movably connected to a threaded rod through a bearing, and one end of the threaded rod away from the second clamping block passes through the second fixed plate and is fixedly connected to a turning handle.

[0031] Here’s how it works:

[0032] When the guide rails 5 and the sliding blocks 6 arranged on both sides of the upper end of the receiving plate 4 receive goods for transmission, the hydraulic cylinders 2 installed on the three sides of the bottom of the frame 1 can cooperate with the support frame 3 connected to the top to achieve stable reception of the receiving plate 4. In this way, the receiving plate 4 can achieve efficient unloading reception of the guide rails 5 and the sliding blocks 6, ensuring the stability of the goods receiving and transmission process, and ensuring the accuracy and stability of subsequent machine tool processing activities;

[0033] In order to further improve the load-bearing effect of unloading, an adjustable reinforcement device 8 is provided on the left and right sides of the support frame 3, that is, the receiving strips 83 on both sides installed inside the adjustable reinforcement device 8 can be stably abutted against the bottom of the receiving plate 4 to achieve lateral receiving reinforcement cooperation, so that the load-bearing effect of the receiving plate 4 is improved. Secondly, the shock-absorbing structure 89 provided in the middle of the upper end of the support plate 81 can also be abutted against the bottom of the receiving plate 4, that is, the abutment plate 893 provided inside the shock-absorbing structure 89 can cooperate with the sphere provided on the top to be dispersedly abutted against the bottom of the receiving plate 4 in series, so as to further improve the overall load-bearing and unloading effect of the receiving plate 4, and the first telescopic rod 892 and the second telescopic rod 898 installed inside the shock-absorbing structure 89 can be squeezed and contracted, and when the second telescopic rod 898 contracts, the second telescopic rod 892 and the second telescopic rod 898 can be squeezed and contracted. At this time, the spring 899 built into the second telescopic rod 898 can perform elastic shock absorption and buffering cooperation. At the same time, the second telescopic rod 898 compressed on both sides will expand outward to realize the horizontal push of the movable block 895 connected at the bottom. In this way, the movable block 895 can move smoothly along the cross bar 894 laterally inserted on the left and right sides of the upper end of the connecting seat 891 to squeeze the damper 896 and the compression spring 897 respectively, so that the damper 896 and the compression spring 897 cooperate with each other to achieve the improvement of the elastic shock absorption and buffering effect, thereby improving the overall bearing and unloading effect of the receiving plate 4, so that the guide rail 5 and the sliding block 6 are in a flat state during the moving transmission process, thereby achieving the advantages of multiple unloading cooperation of the sliding guide rail and improving the running stability of the sliding guide rail.

[0034] Secondly, when the connection state and position of the connection bar 83 and the shock absorbing structure 89 need to be adjusted, the servo motor 88 can be driven to realize the rotation of the worm 87. As the worm 87 rotates, the worm wheel 86 meshed with the upper end of the worm 87 will rotate and synchronously drive the screw 85 connected in the middle.
