Description

Technical Field

[0001] This utility model relates to the field of mechanical cutting tool technology, specifically a mechanical cutting tool quenching lifting frame. Background Technology

[0002] The quenching rack for mechanical cutting tools has insufficient stability during the quenching process.

[0003] The main reason is that the quenching rack for mechanical tools needs to be moved horizontally and vertically during the quenching process. In the existing quenching rack, which is a fixed structure, the horizontal and vertical movements are all done by the lifting device located at the top. However, under such operation, there is unstable swaying between the lifting device and the quenching rack. This affects the position of the mechanical tools during the lifting process, which can easily cause collisions between the quenching tools. Before the mechanical tools have completed quenching, they are prone to damage, which increases production costs. Utility Model Content

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.

[0018] Please see Figure 1-3A mechanical tool quenching lifting frame includes a fixed frame 1. A motor is fixedly installed at the center of the fixed frame 1, and a stepper screw 2 is connected to the bottom end of the motor. A lifting platform 31 is provided on the outer side of the stepper screw 2, and the lifting platform 31 is threadedly connected to the stepper screw 2. A quenching frame 3 is fixedly installed on the top of the lifting platform 31. A support plate 6 is fixedly connected to the top of the fixed frame 1, and a stabilizing plate 5 is fixedly connected to the top of the support plate 6. Four sets of positioning vertical plates 11 are fixedly connected to the outer side of the fixed frame 1. Each set of positioning vertical plates 11 has two parallel plates, and a positioning horizontal plate 51 is fixedly connected to the outer side of the stabilizing plate 5. After passing through the positioning vertical plate 11 and the positioning horizontal plate 51 in sequence, the top ends of the four positioning ropes 12 are connected to the moving mechanism. After passing through the positioning horizontal plate 51, the positioning ropes 12 are converted into loops and are respectively looped around the two positioning vertical plates 11, so that the rope structure on the positioning horizontal plate 51 and the two positioning vertical plates 11 forms a triangle. During the movement of the fixed frame 1, the positioning ropes 12 pass through the positioning vertical plate 11 and the positioning horizontal plate 51 in sequence, and the top ends of the four positioning ropes 12 are connected to the moving mechanism. After passing through the positioning horizontal plate 51, the positioning ropes 12 are converted into loops and are respectively looped around the two positioning vertical plates 11, forming a triangular structure. The triangle has stability. During the operation of the lifting frame, whether it is the vibration generated by the lifting platform 31 driving the quenching frame 3 to move up and down, or the external impact force that may be received, the positioning ropes 12 and the formed triangular structure can effectively disperse and bear these forces.

[0019] Furthermore, the interior of the quenching frame 3 is provided with a groove for quenching mechanical tools, and a receiving mesh 33 is provided inside the groove. The receiving mesh 33 is fixedly connected to the quenching frame 3. The mechanical tools are placed in the groove, and the water in the quenching pool submerges the receiving mesh 33 to quench the mechanical tools.

[0020] Furthermore, guide holes 32 are provided at both ends of the lifting platform 31. The guide holes 32 are penetrated by guide rods 4, and the top end of the guide rods 4 is fixedly connected to the fixed frame 1. The guide rods 4 keep the lifting platform 31 stable during the lifting process.

[0021] Furthermore, the connecting mesh 33 connects the interior and exterior of the quenching frame 3.

[0022] Furthermore, the receiving meshes 33 in two adjacent grooves inside the quenching frame 3 are parallel to each other to prevent the mechanical tools from contacting each other.

[0023] Working Principle: This utility model discloses a mechanical tool quenching lifting frame. During use, as the fixed frame 1 moves, the positioning ropes 12 pass sequentially through the positioning vertical plate 11 and the positioning horizontal plate 51. The tops of the four positioning ropes 12 are connected to the moving mechanism. After passing through the positioning horizontal plate 51, the positioning ropes 12 are converted into loops, which are respectively looped around the two positioning vertical plates 11, forming a triangular structure. The triangle provides stability, effectively dispersing and bearing the vibrations generated by the lifting platform 31 driving the quenching frame 3 up and down, as well as potential external impacts during the lifting frame's operation. After the motor at the center of the fixed frame 1 starts, it drives the stepping screw 2 connected to the bottom to rotate. Since the lifting platform 31 and the stepping screw 2 are threadedly connected, according to the principle of threaded transmission, when the stepping screw 2 rotates, the lifting platform 31 will move linearly along the axial direction of the stepping screw 2, causing the quenching frame 3 to carry the mechanical tool into the quenching tank for quenching.
