Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically a CNC lathe lifting device. Background Technology

[0002] A CNC lathe is a high-precision, high-efficiency automated machine tool that can be programmed according to machining requirements, allowing it to process parts into specified shapes. Existing CNC lathes require lifting devices to move the workpiece during operation.

[0003] An investigation revealed that Chinese utility model patent CN220613173U discloses a CNC lathe lifting device, including a base and a machining table. A support frame is fixedly installed on the top of the base, and lifting grooves are provided at both ends of the front side of the support frame. A lead screw is movably installed inside each lifting groove, and a transmission box is fixedly installed on the top of the support frame. This utility model controls a drive motor to rotate the drive wheel, which in turn rotates the idler wheel. The rotation of the idler wheel and the idler wheel drives the connecting wheel on their outer side. The rotation of the connecting wheel drives the lead screw, which in turn drives the threaded bearing plate to slide upward along the lifting groove, thereby raising the workpiece to the machining table and improving work efficiency. At the same time, the multi-stage transmission of the idler wheel and the idler wheel, with the drive wheel and idler wheel driving the larger one, increases the torque, thus facilitating the transport of heavier workpieces. However, the lifting device only provides simple protection for the object through protective pads during the lifting process. When the object being lifted is a round and easily rolling object, it is easy for the object to roll off the lifting platform due to the vibration of the lifting device, causing the object to fall and break. At the same time, it is also easy for the object to fall and injure the operator.

[0004] Therefore, this utility model provides a CNC lathe lifting device to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This utility model provides a lifting device for CNC lathes, which aims to solve the problems mentioned in the background art, such as the lack of safety protection on the lifting platform of existing lifting devices, the easy for objects on the lifting platform to roll off the platform during the lifting process, causing the objects to fall and break, and also the easy for objects to injure the operators.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a CNC lathe lifting device, comprising a frame and a lifting platform mounted on the frame via a lifting assembly;

[0009] Unlike existing lifting devices, the lifting assembly includes a drive screw threaded into the lifting platform and rotatably connected to the frame. A drive motor is fixedly installed at the top of the frame, and the output end of the drive motor is fixedly connected to the top of the drive screw. A guide rail fixedly connected to the frame is slidably connected to the rear end of the lifting platform. The rear end of the lifting platform contacts the front of the frame. The cooperation between the frame and the guide rail can provide certain support for the lifting platform, reduce the pressure of the lifting platform on the drive screw, and improve the service life of the drive screw.

[0010] To enhance the protection of objects on the lifting platform: a protective assembly is installed at the top of the lifting platform. This assembly includes a protective frame plate, with hinged rods symmetrically fixed to the rear ends of the frame plate. The ends of the hinged rods are hinged to hinged seats fixedly connected to the top of the lifting platform. This protective assembly effectively protects objects on the lifting platform, preventing them from slipping or falling from the platform's edge during lifting due to accidental shaking, collisions, or improper operation. This is especially beneficial for small, easily rolling, or irregularly shaped items, significantly reducing the risk of damage or loss. The frame plate not only protects transported objects but also protects workers below from potential injury, reducing the risk of workplace accidents.

[0011] Preferably, to facilitate the movement of objects from the lifting platform to the processing table: the top of the lifting platform is rotatably and equidistantly fitted with multiple ball bearings; the rotation of the ball bearings can directly move objects from the lifting platform to the processing table, avoiding secondary handling, reducing the labor of operators, and improving production safety.

[0012] Preferably, a motor bracket for mounting the drive motor is fixedly connected to the top of the frame.

[0013] Preferably, in order to improve the strength of the frame and prevent the frame from bending, the rear side of the frame is symmetrically fixedly connected with reinforcing ribs, and a connecting plate is fixedly connected between the two reinforcing ribs.

[0014] Preferably, to prevent the frame from tilting forward due to the influence of objects on the lifting platform: a fixed rod is fixedly connected to the rear side of the top of the frame, and multiple counterweights are slidably sleeved on the fixed rod.

[0015] Preferably, in order to facilitate the axial rotation of the frame, a base is rotatably fitted at the bottom end of the frame.

[0016] Preferably, to facilitate the movement of the lifting device, casters are fixedly connected to the four corners of the bottom of the base; the casters facilitate the movement of the lifting device onto the object to be transported, thereby reducing the need for hoisting, reducing the handling of objects, and further improving production safety.

[0017] (III) Beneficial Effects

[0018] This application utilizes protective components to protect objects located on the lifting platform, effectively preventing objects from slipping or falling off the edge of the lifting platform during lifting due to accidental shaking, collision, or improper operation. This is especially beneficial for small, easily rolling, or irregularly shaped items, greatly reducing the risk of damage or loss. The frame not only protects the transported objects but also protects the workers below from potential injury, reducing the risk of workplace accidents.

[0019] This application utilizes the rotation of ball bearings to directly move objects from one lifting platform to the other, avoiding secondary handling, reducing operator workload, and improving production safety.

[0020] This application utilizes casters to facilitate the movement of the lifting device onto the object to be transported, thereby reducing the need for hoisting, minimizing the handling of objects, and further improving production safety. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides a lifting device for a CNC lathe, such as... Figure 1-5 As shown, the lifting device includes a frame 1 and a lifting platform 3 mounted on the frame 1 via a lifting assembly 2;

[0030] The lifting assembly 2 includes a drive screw 21 threadedly inserted into the lifting platform 3 and rotatably connected to the frame 1. A drive motor 22 is fixedly installed at the top of the frame 1, and the output end of the drive motor 22 is fixedly connected to the top of the drive screw 21. A guide rail 23 fixedly connected to the frame 1 is slidably connected to the rear end of the lifting platform 3. The rear end of the lifting platform 3 contacts the front end of the frame 1. The cooperation between the frame 1 and the guide rail 23 can provide a certain support for the lifting platform 3, reduce the pressure of the lifting platform 3 on the drive screw 21, and improve the service life of the drive screw 21.

[0031] When in use, first place the object with lifting function on the lifting platform 3, then drive the drive screw 21 to rotate clockwise through the drive motor 22. The drive screw 21 drives the lifting platform 3 to move upward through the guide rail 23 until the lifting platform 3 moves to the plane of the CNC lathe's machining table and stops. Then the object can be moved onto the machining table.

[0032] The top of the lifting platform 3 is equipped with a protective component 4, which includes a protective frame plate 41. A hinge rod 43 is symmetrically fixedly connected to the rear end of the protective frame plate 41, and the end of the hinge rod 43 is hinged to a hinge seat 42 fixedly connected to the top of the lifting platform 3. The protective component 4 can protect objects located on the lifting platform 3, effectively preventing objects from slipping or falling from the edge of the lifting platform 3 due to accidental shaking, collision, or improper operation during lifting. This is especially beneficial for small, easily rolling, or irregularly shaped items, significantly reducing the risk of damage or loss. The frame plate not only protects transported objects but also protects workers below from potential injury, reducing the risk of workplace accidents. With the frame plate providing protection... The frame design allows the lifting platform 3 to operate at a more stable and appropriate speed to a certain extent, without excessive concern about the stability of the objects, thereby improving the efficiency of logistics or production processes. The frame design is usually quite flexible and can be adjusted or customized according to goods of different sizes and shapes, making this protective measure suitable for diverse transportation needs. By reducing damage to goods during handling, the additional costs incurred in replacing or repairing damaged items can be significantly reduced, which is beneficial for saving corporate resources and improving economic efficiency in the long run. The frame can also provide additional support points to help fix and stabilize goods, especially when encountering vibration or tilting during lifting, effectively maintaining the balance of goods and preventing tilting or tipping.

[0033] When in use, when it is necessary to move an object onto the lifting platform 3, first hold the protective frame plate 41 by hand, and then drive the protective frame plate 41 to rotate counterclockwise through the cooperation of the hinge seat 42 and the hinge rod 43, so that the protective frame plate 41, which is in a horizontal state, moves to about 100-110°. Then, when the object is moved onto the lifting platform 3, rotate the protective frame plate 41 clockwise to reset the position of the protective frame plate 41, so that the protective frame plate 41 is located outside the object, thereby protecting the object.

[0034] To facilitate the movement of objects from the lifting platform 3 to the processing table: multiple ball bearings 31 are equidistantly embedded at the top of the lifting platform 3; through the rotation of the ball bearings 31, objects located on the lifting platform 3 can be directly moved to the lifting platform 3, avoiding secondary handling, reducing the labor of operators, and improving production safety.

[0035] Furthermore, to facilitate the support and fixed installation of the motor: a motor bracket 221 for installing the drive motor 22 is fixedly connected to the top of the frame 1.

[0036] To improve the strength of the frame 1 and prevent it from bending, the frame 1 is symmetrically fixed with reinforcing ribs 5 on the rear side, and a connecting plate 51 is fixedly connected between the two reinforcing ribs 5.

[0037] To prevent the frame 1 from tilting forward due to the influence of objects on the lifting platform 3, a fixed rod 6 is fixedly connected to the rear top of the frame 1, and multiple counterweights 61 are slidably sleeved on the fixed rod 6.

[0038] To facilitate the axial rotation of the frame 1, a base 7 is rotatably fitted at the bottom of the frame 1.

[0039] To facilitate the movement of the lifting device: swivel casters 8 are fixedly connected to the four corners of the bottom of the base 7. The swivel casters 8 include two movable casters and two fixed casters. The fixed casters can only move in a straight line, while the movable casters can rotate 360° in a plane, making it easy to change the direction of movement of the lifting device. The swivel casters 8 make it easy to move the lifting device onto objects to be transported, thereby reducing the need for hoisting, reducing the handling of objects, and further improving production safety.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
