Description

Technical Field

[0001] This utility model relates to the field of lifting mechanism technology, and in particular to a novel mechanical lifting mechanism. Background Technology

[0002] In the field of mechanical manufacturing, especially in the welding of small-diameter piston rods, a lifting mechanism is needed to adapt the piston rod to the correct height and provide stable support to ensure welding accuracy and operational safety. Currently, mechanical lifting mechanisms in such scenarios mostly use cylinders for height adjustment. These mechanisms are widely used due to their simple structure and low cost. However, in actual operation, the cylinders cannot remain at the appropriate intermediate height, requiring operators to place temporary supports such as wooden blocks or metal shims at the end of the piston rod. This not only increases the number of steps but also increases the risk of piston rod tilting due to displacement of the supports. Furthermore, cylinder-based lifting mechanisms are mostly fixed structures, making them unsuitable for welding piston rods of different diameters, resulting in poor adaptability. Therefore, we propose a novel mechanical lifting mechanism. Utility Model Content

[0018] Example

[0019] like Figure 1-3 As shown, this utility model proposes a novel mechanical lifting mechanism, including a base assembly 1 and a lifting mechanism 2. The base assembly 1 includes a base plate 11. Multiple sets of reinforcing plates 12 are arranged symmetrically on one side of the upper part of the base plate 11. The mounting end of each set of reinforcing plates 12 is respectively installed on the upper part of the base plate 11. The mounting end of the reinforcing plate 12 is fixedly connected to the upper part of the base plate 11. An adjusting cylinder 13 is provided at the middle position of the multiple sets of reinforcing plates 12 on the base plate 11. The adjusting cylinder 13 is hollow and threaded. The mounting end of the adjusting cylinder 13 is connected to the base plate 11. The upper side of the plate 11 is correspondingly installed, and the mounting end of the adjusting cylinder 13 is fixedly connected to the upper side of the base plate 11. The outer side of the adjusting cylinder 13 is correspondingly installed with one end close to each other with multiple sets of reinforcing plates 12. The outer side of the adjusting cylinder 13 is fixedly connected with one end close to each other with multiple sets of reinforcing plates 12. The arrangement of multiple sets of reinforcing plates 12 can make the adjusting cylinder 13 and the base plate 11 more stable when they are assembled. Both ends of the base plate 11 are provided with assembly holes 14. The assembly holes 14 are U-shaped. The arrangement of the assembly holes 14 facilitates the operator and flange to adapt and install. The base assembly 1 can stably assemble the lifting mechanism 2.

[0020] The lifting mechanism 2 includes a lifting base 21 located above the adjusting cylinder 13. An adjusting screw 22 is disposed below the lifting base 21. The mounting end of the adjusting screw 22 is correspondingly installed on one side of the lower part of the lifting base 21 and is fixedly connected to it. The outer thread of the adjusting screw 22 is a trapezoidal thread. The adjusting screw 22 is threadedly connected to the adjusting cylinder 13. The trapezoidal thread design provides good self-locking capability and high transmission efficiency when the adjusting screw 22 and the adjusting cylinder 13 are threadedly connected. A large handwheel 23 is disposed on the outer side of the lifting base 21. The mounting end of the large handwheel 23 is correspondingly installed on the outer side of the lifting base 21 and is fixedly connected to it. The large handwheel 23 allows the operator to rotate the adjusting screw 22 via the lifting platform 21, thereby enabling stable height adjustment of the lifting platform 21 through the threaded connection between the adjusting screw 22 and the adjusting cylinder 13. A stabilizing cover 24 is located above the large handwheel 23 on the outside of the lifting platform 21, with its lower side fitting against the upper side of the large handwheel 23. A positioning pin 29 is located at the center of the top of the lifting platform 21, with its mounting end fixedly connected to the upper side of the lifting platform 21. A column hole is located at the center of the stabilizing cover 24, with the outer side of the positioning pin 29 fitting against the inner wall of the column hole. The outer ring of the positioning pin 29 is rotatably connected to the column hole, and the top end of the positioning pin 29 passes through... The stabilizing cover 24 and the positioning pin 29 limit its movement. Multiple sets of steel balls 25 are arranged between the outer ring of the lifting base 21 and the inner wall of the stabilizing cover 24. A steel ball groove 3 is provided on the outer side of the lifting base 21, and the multiple sets of steel balls 25 are evenly arranged in the groove 3. The multiple sets of steel balls 25 are rotatably connected to the inner wall of the groove 3. The steel ball groove 3 limits the movement of the multiple sets of steel balls 25. The arrangement of the multiple sets of steel balls 25 allows the stabilizing cover 24 to rotate outside the lifting base 21, while preventing the adjusting screw 22 from exceeding the usable height after one rotation. Multiple sets of pins 26 are provided on the outer ring of the stabilizing cover 24, and multiple sets of positioning bolt holes are provided on the large handwheel 23. The pins 26 are installed correspondingly to the bolt holes and are fixedly connected. A positioning ring groove is provided on the outer periphery of the lifting base 21 below the steel ball groove 3. The top end of the pin 26 is installed correspondingly to the positioning ring groove. The positioning ring groove can limit the movement of the stabilizing cover 24 again with the top end of the pin 26, thereby ensuring that the stabilizing cover 24 is more stable when rotating through the steel ball 25, and at the same time preventing the steel ball 25 from accidentally falling out. A roller seat 27 is provided on the upper side of the stabilizing cover 24. The mounting end of the roller seat 27 is installed correspondingly to the upper side of the stabilizing cover 24 and is fixedly connected to the upper side of the stabilizing cover 24. A nylon roller 28 is provided on the roller seat 27 and is correspondingly mounted on the roller seat 27. The mounting end of the nylon roller 28 is rotatably connected to the roller seat 27.The nylon roller 28 is designed to prevent damage to the workpiece. The lifting mechanism 2 allows for free adjustment of the nylon roller 28's height based on the diameter of the piston rod to be welded, and the large pitch reduces adjustment time.

[0021] In this embodiment, when the operator performs welding operations on the piston rod using this device, the operator adjusts the height of the nylon roller 28 according to the diameter of the piston rod to be welded. The operator rotates the large handwheel 23, which drives the adjusting screw 22 to rotate in the adjusting cylinder 13 via the lifting base 21. At this time, the adjusting screw 22 achieves height adjustment within the adjusting cylinder 13 through its threaded connection with the adjusting cylinder 13. Thus, the adjusting screw 22 drives the lifting base 21 to adjust its height. During the height adjustment operation, the lifting base 21 drives the nylon roller 28 to complete the height adjustment operation through the stabilizing cover 24 and the roller seat 27, so that the height of the nylon roller 28 is adapted to the operational requirements of the piston rod to be welded.

[0022] When the operator rotates the large handwheel 23 once and causes the nylon roller 28 to be too high, the operator can rotate the large handwheel 23 in the opposite direction according to the work requirements until the height of the nylon roller 28 meets the work requirements. Then, the operator can rotate the stabilizing cover 24. The stabilizing cover 24, under the action of multiple sets of steel balls 25, drives the nylon roller 28 to rotate and adjust through the roller seat 27 outside the lifting platform 21, so that the nylon roller 28 can adapt to the work requirements of different heights.

[0023] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
