Description
Technical Field
[0001] This utility model relates to the field of automated loading and unloading technology for machine tools, and in particular to a guide rail side-mounted vertical shaft lead screw lifting module. Background Technology
[0002] The machine tool automated loading and unloading fork arm is a key component in automated machine tool loading and unloading equipment. It is mainly used to grab and transport workpieces, realize automatic loading and unloading operations in the machine tool processing, thereby improving production efficiency, reducing labor costs, and improving product quality stability. The lifting and lowering of the machine tool is achieved through a lead screw and guide rail structure.
[0003] In existing lead screw lifting modules, the lead screw and guide rail are located on the same side, and the end faces of the two guide rails are in the same plane. When there is a deviation of a few tenths of a millimeter between the lead screw and the guide rail, the lead screw or guide rail needs to be adjusted repeatedly, resulting in low adjustment efficiency. Furthermore, during lifting, the force is mainly borne by the screws on the guide rail, resulting in low load-bearing capacity.
[0004] To address this, we propose a guide rail side-mounted vertical shaft lead screw lifting module. Utility Model Content
[0005] To address the shortcomings of the existing production technology, the applicant provides a guide rail side-mounted vertical shaft lead screw lifting module. This module allows for easier adjustment by loosening the screws between the connecting slider and the connecting block, using the gap between the screws and the through hole to compensate for dimensional errors between the lead screw axis and the guide rail axis caused by machining and installation, and then tightening the screws between the connecting slider and the connecting block.
[0006] The technical solution adopted in this utility model is as follows:
[0007] A guide rail side-mounted vertical shaft lead screw lifting module includes:
[0008] frame;
[0009] The motor is mounted on the frame, and a lead screw is fixed on the output shaft of the motor. A lead screw nut seat is matched and installed on the lead screw.
[0010] The lifting frame is fixedly connected to the lead screw nut seat;
[0011] There are two guide rails, and both guide rails are located on one side of the frame;
[0012] The guide rail is equipped with a slider, and the slider has a threaded hole; both sides of the lifting frame are equipped with connecting blocks, and the connecting blocks have through holes corresponding to the threaded holes, and the diameter of the through holes is larger than the diameter of the threaded holes.
[0013] The guide rail is connected to the limit plate by screws. The limit plate is fixed on the frame. A step is provided on the side of the limit plate near the lifting frame, and the guide rail is set against the step.
[0014] Its further features are:
[0015] The motor is mounted on a motor frame, the motor frame is mounted on a connecting rod, and the connecting rod is mounted on a machine frame.
[0016] One end of the lead screw is mounted on the frame via a bearing seat.
[0017] The lead screw nut seat is connected to the lifting frame by screws.
[0018] The end faces of the two guide rails are arranged in parallel.
[0019] The beneficial effects of this utility model are as follows:
[0020] This utility model has a compact and reasonable structure and is easy to operate. When there is a slight deviation between the lead screw and the guide rail, the screws between the connecting slider and the connecting block are loosened. The gap between the screws and the through hole compensates for the dimensional error between the lead screw axis and the guide rail axis caused by processing and installation. Then, the screws between the connecting slider and the connecting block are tightened. This allows for quick adjustment without having to adjust the guide rail or lead screw. When there is a slight deviation between the lead screw and the guide rail, the adjustment is faster and more convenient.
[0021] In addition, this utility model also has the following advantages:
[0022] (1) The guide rail is fixed to the frame by a limiting plate. The limiting plate has a step on the side of the limiting plate near the lifting frame. The guide rail is fixed to the limiting plate and is set against the step of the limiting plate. The guide rail is connected to the limiting plate by screws. When the lifting frame is raised and lowered, the platform restricts the guide rail, so that the screws connecting the guide rail and the limiting plate are subjected to less force, thereby increasing the load-bearing capacity.

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0032] like Figures 1-7 As shown, a guide rail side-mounted vertical shaft screw lifting module includes a frame 1, a screw 2, a screw nut seat 3, a motor 4, a guide rail 5, a slider 6, a lifting frame 7, and a limit plate 8.
[0033] Motor 4 is mounted on frame 1 via connecting rod 402. Motor 4 is mounted on motor frame 401, and motor frame 401 is mounted on connecting rod 402. One end of lead screw 2 is fixedly connected to the output shaft of motor 4, and the other end of lead screw 2 is mounted on frame 1 via bearing seat.
[0034] The lead screw nut seat 3 is matched and installed on the lead screw 2. The lead screw nut seat 3 is detachably connected to the lifting frame 7. Both sides of the lifting frame 7 are provided with connecting blocks 701, and the connecting blocks 701 are provided with through holes 702.
[0035] In one embodiment, the lead screw nut seat 3 is connected to the lifting frame 7 by screws.
[0036] Guide rails 5 are provided on both sides of the frame 1, and sliders 6 are matched on the guide rails 5. The sliders 6 are provided with threaded holes 601 corresponding to the through holes 702. The diameter of the through holes 702 is larger than the diameter of the threaded holes 601. Screws pass through the through holes 702 and connect with the threaded holes 601, so that the connecting block 701 and the sliders 6 are connected.
[0037] The end faces of the two guide rails 5 are set in parallel.
[0038] In one embodiment, the guide rail 5 is fixed to the frame 1 by a limiting plate 8. The limiting plate 8 is fixed to the frame 1 and has a step 801 on the side near the lifting frame 7. The guide rail 5 is fixed to the limiting plate 8 and is set against the step 801 of the limiting plate 8. The guide rail 5 is connected to the limiting plate 8 by screws. When the lifting frame 7 rises and falls, the platform 801 restricts the guide rail 5, reducing the stress on the screws connecting the guide rail 5 and the limiting plate 8, thereby increasing the load-bearing capacity.
[0039] In practical use, when there is a slight deviation of a few millimeters between the lead screw 2 and the guide rail 5, the screws between the connecting slider 6 and the connecting block 701 can be loosened. The gap between the screws and the through hole 702 compensates for the dimensional error between the axis of the lead screw 2 and the axis of the guide rail 5 caused by machining and installation. Then, the screws between the connecting slider 6 and the connecting block 701 can be tightened. This allows for quick adjustment without having to adjust the guide rail 5 or the lead screw 2. When there is a slight deviation of a few millimeters between the lead screw 2 and the guide rail 5, the adjustment is faster and more convenient.
[0040] The motor 4 drives the lead screw 2 to rotate. The lead screw 2 and the lead screw nut seat 3 work together to drive the lifting frame 7 to rise and fall. The lifting frame 7 drives the slider 6 to slide on the guide rail 5 through the connecting block 701. The gap between the screw and the through hole 702 compensates for the dimensional error between the axis of the lead screw 2 and the axis of the guide rail 5 caused by processing and installation. When there is a deviation of a few millimeters between the lead screw 2 and the guide rail 5, the adjustment is quicker and more convenient.
[0041] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
