Description

Technical Field

[0001] This application relates to the field of screw production equipment technology, specifically to an auxiliary screw loading and unloading device. Background Technology

[0002] In the field of machinery manufacturing, screws are key basic components of various mechanical equipment, and their processing quality and efficiency play a crucial role in the performance of the final product. Currently, most screw manufacturers still rely mainly on manual operation or relatively simple auxiliary equipment in the loading and unloading process.

[0003] Manual screw loading and unloading has significant drawbacks. On the one hand, the labor intensity of workers is extremely high, as they need to repeatedly move heavy objects. Long-term high-intensity work can easily lead to fatigue, resulting in frequent operational errors. For example, if the hand is slightly unsteady when grabbing the screw, it may cause the screw to fall or be bumped, damaging its surface precision, affecting subsequent processing, or even being scrapped directly.

[0004] On the other hand, manual operation is greatly affected by subjective factors, making it difficult to accurately control the screw placement position, resulting in poor accuracy and stability of loading and unloading, which in turn causes product quality fluctuations, increases processing and adjustment time, and reduces equipment operating efficiency.

[0005] Simple auxiliary equipment, such as the common overhead crane for single-screw hoisting, can alleviate the heavy physical labor of manual handling to some extent, but it also has many limitations. It has poor operational flexibility. When facing screw processing tasks of different specifications and batches, hoisting preparation and positioning take a long time. Moreover, the screw is prone to swinging significantly during hoisting, which poses a risk of collision with surrounding equipment. Once a collision occurs, not only will the screw and equipment be damaged, but it may also cause a safety accident and pose a safety threat to the operators. Utility Model Content

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0035] Please see Figure 1-5 The embodiments provided by this utility model are as follows:

[0036] like Figure 1 As shown, an auxiliary screw loading and unloading device includes a loading and unloading platform 1. A frame 2 is fixedly installed at the bottom of the loading and unloading platform 1. The frame 2 serves as the support structure for the entire device, providing an installation foundation and stable support for other components. A translation mechanism 3 is fixedly installed at the top of the frame 2.

[0037] Specifically, such as Figure 2 As shown, the translation mechanism 3 includes a guide rail 31, a slide 32, a moving plate 33, a motor 34, a lead screw 35, a threaded seat 36, and a bearing seat 37. The guide rail 31 is fixedly installed on the top two sides of the frame 2. The slide 32 is slidably connected to the side wall of the guide rail 31. Both ends of the moving plate 33 are fixedly installed on the slide 32. The threaded seat 36 is fixedly installed on the top surface of the slide 32. The lead screw 35 is threadedly connected to the inside of the threaded seat 36. One end of the lead screw 35 is fixedly installed to the output shaft of the motor 34 through a coupling. The motor 34 is fixedly installed on the side wall of the frame 2. The other end of the lead screw 35 is rotatably installed in the bearing seat 37. The bearing seat 37 is installed on the bottom surface of the frame 2.

[0038] After motor 34 is powered on, the output shaft rotates, driving lead screw 35 to rotate. Since threaded seat 36 is threadedly connected to lead screw 35 and is fixedly mounted on slide 32, the threaded seat 36 moves along the axis of lead screw 35 under the rotation of lead screw 35, thereby driving slide 32 to slide on guide rail 31. Because both ends of moving plate 33 are fixedly mounted on slide 32, the movement of slide 32 drives moving plate 33 to perform translational movement. Guide rail 31 provides guidance for the sliding of slide 32, ensuring the linearity and stability of the translation of moving plate 33.

[0039] The translation mechanism 3 enables the moving plate 33 to move in the horizontal direction, which in turn drives the lifting mechanism 4 and the clamping mechanism 5 installed on the moving plate 33 to move in the horizontal direction, so that the clamping mechanism 5 can perform horizontal displacement between the loading and unloading table 1 and other processing positions (such as processing equipment), thereby realizing the horizontal transport of the screw between different positions.

[0040] like Figure 3 As shown, a lifting mechanism 4 is fixedly installed on the bottom surface of the translation mechanism 3. The lifting mechanism 4 includes a vertical plate 41, a mounting plate 42, a second motor 43, a second lead screw 44, a movable seat 45, a second slide 46, and a second guide rail 47. The top surface of the vertical plate 41 is fixedly installed on both sides of the bottom surface of the movable plate 33. The mounting plate 42 is fixedly installed on the side wall of the vertical plate 41. The side walls of the vertical plate 41 are fixedly installed to the second guide rail 47 near both sides. The second slide 46 is slidably installed on the second guide rail 47. The second motor 43 is fixedly installed on the top surface of the mounting plate 42. The output shaft of the second motor 43 is fixedly installed to one end of the second lead screw 44 through a coupling. The other end of the second lead screw 44 is rotatably installed on the side wall of the vertical plate 41 through a shaft seat. A second threaded seat is fixedly installed at the bottom of the movable seat 45. The second threaded seat is threadedly connected to the side wall of the second lead screw 44. The side wall of the movable seat 45 is fixedly installed to the fixed plate 51.

[0041] After the second motor 43 is powered on, the output shaft rotates, driving the second lead screw 44 to rotate. The threaded seat 2 at the bottom of the moving seat 45 is threadedly connected to the second lead screw 44. Under the rotation of the second lead screw 44, the threaded seat 2 moves along the axis of the second lead screw 44, thereby driving the moving seat 45 to move up and down on the guide rail 47. The guide rail 47 is fixedly installed on the side wall of the vertical plate 41, providing guidance for the sliding of the second slide 46, ensuring the linearity and stability of the moving seat 45's lifting and lowering, and enabling the clamping mechanism 5 to reach different heights, such as descending to a suitable height at the loading and unloading platform 1 to grab the screw, and rising to a suitable height at the processing equipment to place the screw, meeting the needs of different height positions during the screw loading and unloading process.

[0042] It is worth noting that both ends of guide rail 31 and guide rail 47 are equipped with travel limiters, so that when the moving plate 33 and the moving seat 45 move to the ends of guide rail 31 and guide rail 47, the travel limiters can be triggered to stop motor 34 and motor 43 from working.

[0043] like Figure 4 and Figure 5 As shown, the side wall of the lifting mechanism 4 is equipped with a clamping mechanism 5 for picking up and putting down the screw. The clamping mechanism 5 includes a fixed plate 51, a fixed seat 52, a thumb cylinder 53, a fixed clamping seat 54, and a movable clamping seat 55. The fixed plate 51 is fixedly installed on the side wall of the lifting mechanism 4, the fixed seat 52 is fixedly installed on the side wall of the fixed plate 51, the thumb cylinder 53 is installed on the top surface of the fixed seat 52, the bottom side wall of the fixed seat 52 is fixedly installed with the fixed clamping seat 54, the movable clamping seat 55 is slidably installed on the fixed seat 52, and the piston rod of the thumb cylinder 53 is fixedly installed with the movable clamping seat 55 with the frame 2.

[0044] Among them, the top surface of the fixed seat 52 is provided with sliding grooves 56 on both sides, and the side wall of the movable clamp seat 55 is fixedly connected with a sliding plate 57. The sliding plate 57 slides in the sliding groove 56, and the piston rod of the thumb cylinder 53 is fixedly installed at the end of the sliding plate 57.

[0045] After the thumb cylinder 53 is vented, the piston rod extends and retracts. When the piston rod extends, it pushes the movable clamp 55, which is fixedly installed with the piston rod, to slide in the slide groove 56 of the fixed seat 52, so that the movable clamp 55 moves closer to the fixed clamp 54. When the piston rod retracts, it pulls the movable clamp 55 to move away from the fixed clamp 54, thereby realizing the gripping and release of the screw.

[0046] It is worth noting that the fixed clamp 54 and the movable clamp 55 are mirror images mounted on the side wall of the fixed base 52, and the fixed clamp 54 and the movable clamp 55 are both provided with "V" shaped clamping grooves 58 on their opposite sides. Since the fixed clamp 54 and the movable clamp 55 are both provided with "V" shaped clamping grooves 58 on their opposite sides, when the movable clamp 55 moves closer to the fixed clamp 54, the two "V" shaped clamping grooves 58 can clamp the screw.

[0047] like Figure 1 As shown, a material rack 6 is installed on the top surface of the material pick-and-place platform 1. The top surface of the material rack 6 has multiple arc-shaped grooves 61 for placing screws. The multiple arc-shaped grooves 61 are adapted to the shape of the screws. When the screw is placed in the arc-shaped grooves 61, the outer surface of the screw contacts the inner surface of the arc-shaped grooves 61. Due to the constraint of the arc-shaped grooves 61, the screw can be stably placed on the material rack 6.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
