Description

Technical Field

[0001] This utility model relates to the field of automated equipment manufacturing, and in particular to a lifting and clamping device. Background Technology

[0002] In the rapid development of modern industrial production, the fixing, handling, processing, and positioning of materials have become crucial links in the efficient operation of automated production lines. With the deepening of the Industry 4.0 concept and the widespread application of intelligent manufacturing technologies, enterprises are increasingly demanding higher levels of automation and intelligence in their production equipment. In material handling, precise positioning and efficient conveying directly impact product quality and production efficiency. Especially in scenarios involving multi-station collaborative operations and material handling between different devices, there is an urgent need for a device that can flexibly adapt to different working conditions to meet the needs of complex production environments. Lifting and clamping devices have thus become a key research and development focus in the industrial field.

[0003] Currently, there are various mechanical structures and technical principles used in material handling. Regarding lifting functions, some equipment employs chain-type or hydraulic lifting structures. Chain-type lifting uses a motor to drive a sprocket, utilizing the chain's traction to raise and lower the platform; its principle is simple, but its precision is limited. Hydraulic lifting relies on a hydraulic pump to provide power, using the extension and retraction of hydraulic cylinders to drive the platform. While it can bear heavier loads, it suffers from slow response speed and high maintenance costs. For clamping functions, common methods include mechanical lever clamping and pneumatic clamping. Mechanical lever clamping uses a lever mechanism driven manually or by a motor to clamp and fix materials; however, this is cumbersome and difficult to control precisely. Pneumatic clamping uses compressed air to drive a cylinder, which in turn moves the grippers; however, its clamping force is greatly affected by air pressure fluctuations, resulting in poor stability.

[0004] However, existing material handling equipment generally suffers from low positioning accuracy, poor applicability, and a tendency to accumulate errors. Since lifting and clamping functions are often independent, frequent adjustments to equipment parameters or changes to tooling fixtures are required when docking at different heights or handling materials of different sizes. This is not only time-consuming and labor-intensive but also prone to accumulating errors during repeated material handling, leading to material positioning deviations and affecting subsequent processing accuracy and product quality. Furthermore, single-function equipment struggles to meet diverse production needs and adapt to rapidly changing industrial production scenarios, becoming a bottleneck restricting production efficiency. Therefore, a lifting and clamping device is proposed to address these issues. 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.

[0034] Reference Figures 1-7This utility model provides an embodiment of a lifting and clamping device, comprising a lifting device 4, characterized in that: a bearing platform 1 is provided on the top of the lifting device 4, the bearing platform 1 is made of high-strength aluminum alloy, and its surface is anodized, which not only has good wear resistance and corrosion resistance, but also effectively prevents the material surface from being scratched. The bearing platform 1 is used to carry materials, providing a stable support plane for the placement and transportation of materials. For example, in an automated production line, it can stably carry different types of materials such as automotive parts and electronic products. A clamping device 2 is fixedly connected to the outer wall of the lifting device 4, and limiters 3 are fixedly connected to both sides of the bearing platform 1. The limiters 3 are made of rubber and have a certain degree of elasticity, which can limit the materials placed on the bearing platform 1 without damaging the materials, preventing the materials from sliding or tipping to the sides during transportation. An outer cover 7 is provided inside the lifting device 4. The outer cover 7 is a closed structure welded from steel plates, which plays a role in protecting and supporting the internal components, effectively preventing dust and debris from entering the device, and providing a stable support for the internal transmission components. The installation base is fixed. Inside the outer cover 7, a rectangular array of linear bearings 6 are fixedly connected. At the bottom of the bearing platform 1, a rectangular array of optical axis fixing seats 5 are fixedly connected. At the bottom of the optical axis fixing seat 5, a guide shaft 8 is fixedly connected. The outer wall of the guide shaft 8 is slidably connected inside the linear bearings 6. Inside the outer cover 7, a fixing seat 10 is fixedly connected. At the top of the fixing seat 10, a motor 9 is fixedly connected. At the output end of the motor 9, a synchronous pulley 11 is fixedly connected. At the bottom of the outer cover 7, a synchronous pulley 13 is rotatably connected. Synchronous belts 12 are provided on the outer walls of synchronous pulleys 11 and 13. At the top of synchronous pulley 13, a lead screw 14 is fixedly connected. The synchronous belt 12 is made of polyurethane and the inner core is made of high-strength steel wire. It has the advantages of high transmission efficiency, accurate transmission ratio, and no need for lubrication.Synchronous pulley 11, synchronous belt 12, and synchronous pulley 2 13 work together to transmit the rotational motion of motor 9 to lead screw 14, achieving stable transmission and reduced noise. A fixing seat 2 15 is provided on the bottom outer wall of lead screw 14, and the outer wall of fixing seat 2 15 is fixedly connected to the inside of the bottom end of outer cover 7. A fixing seat 3 19 is provided on the top outer wall of lead screw 14, and the outer wall of fixing seat 3 19 is fixedly connected to the inside of the top end of outer cover 7. Both fixing seat 2 15 and the top fixing seat 3 19 are made of cast steel, and their outer walls are fixedly connected to the bottom and top ends of outer cover 7 respectively to fix lead screw 14 and ensure the stability of lead screw 14 during rotation. A nut 16 is threaded onto the outer wall of lead screw 14, and a lifting plate 17 is fixedly connected to the outer wall of nut 16. A rectangular array of lifting columns 18 are fixedly connected to the top of the lifting plate 17. The top of the lifting columns 18 is fixedly connected to the bottom of the bearing platform 1. A fixed base 21 is provided inside the clamping device 2. An electromagnetic push rod 24 is fixedly connected inside the fixed base 21. A clamping plate 20 is fixedly connected to the output end of the electromagnetic push rod 24. A guide shaft 22 is fixedly connected to the outer wall of the clamping plate 20. A linear bearing 23 is fixedly connected inside the fixed base 21. The outer wall of the guide shaft 22 is slidably connected to the inside of the linear bearing 23. The guide shafts 22 on both sides of the clamping plate 20 cooperate with the linear bearings 23 in the fixed base 21 to slide linearly, achieving precise guidance and preventing the clamping plate 20 from shifting, making the clamping process more stable and reliable.

[0035] Specifically, in actual industrial production scenarios, when material transfer is required, the electromagnetic push rod 24 is activated first. Made of high-permeability silicon steel, the electromagnetic push rod 24 is equipped with a high-precision electromagnetic coil and achieves precise control through pulse width modulation (PWM) technology. Its maximum thrust reaches 500N, enabling rapid response to control commands. After activation, the electromagnetic push rod 24, with its strong and stable telescopic force, moves the clamping plate 20 horizontally, allowing for flexible adjustment of material placement specifications. The clamping plate 20 is covered with an anti-slip rubber pad, which not only increases friction with the material but also effectively prevents damage to the material surface during clamping. During the movement of the clamping plate 20, the guide shafts 22, fixedly connected to both sides, slide smoothly within the linear bearings 23. The guide shafts 22 are made of hardened alloy steel with a surface hardness of HRC55 or higher. The linear bearings 23 use self-lubricating engineering plastic combined with a precision ball bearing structure. Together, they form a high-precision guiding system that effectively restricts clamping. The movement trajectory of the clamping plate 20 is carefully controlled to prevent slippage or misalignment, ensuring the accuracy and reliability of the adjustment process. After the specifications are adjusted, the material is placed on top of the carrying platform 1. The limiting components 3 on both sides of the carrying platform 1 immediately come into play. The limiting components 3 are adjustable elastic rubber blocks, fixed to the carrying platform 1 with bolts. They can be flexibly adjusted according to the size of the material, initially limiting the material from the front and rear directions to prevent horizontal displacement. Then, the electromagnetic push rod 24 is activated in the reverse direction, causing the telescopic rod to retract and drive the clamping plate 20 to move towards the center, thereby firmly clamping and fixing the material, ensuring that the material remains stable in subsequent operations, even in high-speed transmission or vibration environments. When the height of the material needs to be adjusted, the motor 9 can be started. The motor 9 is a servo motor equipped with a 20-bit absolute encoder, with a positioning accuracy of ±0.01mm, enabling precise speed and position control. After the motor 9 is started, its output shaft drives the synchronous pulley 11 to rotate at high speed. Both synchronous pulley 11 and synchronous pulley 13 are made of high-strength aluminum alloy with a hard anodized surface, exhibiting excellent wear resistance. Synchronous pulley 11 transmits motion to synchronous pulley 13 below the lead screw 14 via synchronous belt 12. Synchronous belt 12 uses a polyurethane matrix combined with Kevlar fiber reinforcement, offering advantages such as high transmission efficiency, accurate transmission ratio, and no need for lubrication. The rotation of synchronous pulley 13 drives the lead screw 14 to rotate. The lead screw 14 is fixed inside the outer cover 7 by fixed seat 2 15 and fixed seat 3 19. Both fixed seats are made of cast steel and undergo precision machining and aging treatment, providing stable and reliable support for the lead screw 14. When the lead screw 14 rotates, the nut 16 that mates with it moves up and down along the axis of the lead screw 14. The nut 16 drives the lifting plate 17 to move, and the lifting plate 17, through four evenly arranged lifting columns 18, achieves height adjustment of the bearing platform 1.When the carrying platform 1 is raised and lowered, the guide shaft 8 fixed at its bottom slides inside the linear bearing 6. This guide structure can effectively limit the shaking of the carrying platform 1 and maintain the smoothness of the height adjustment process, thereby achieving stable and precise height adjustment of materials and meeting the docking needs of different production stations.

[0036] Working principle: When transferring materials, the electromagnetic push rod 24 can be activated, which drives the clamping plate 20 to move and adjust the placement specifications. Simultaneously, as the clamping plate 20 moves, the guide shaft 22 slides within the linear bearing 23, limiting its movement to prevent slippage or misalignment. The material is then placed on top of the carrying platform 1 and limited by the limiting component 3. Then, the electromagnetic push rod 24 is activated in reverse to retract the clamping plate 20, clamping and fixing the material stably. When height adjustment is needed, the motor 9 can be activated, driving the synchronous pulley 11 to rotate. The timing belt 12 is driven to rotate by the timing pulley 11, which in turn drives the timing pulley 13 to rotate, thereby driving the lead screw 14 to rotate. The lead screw 14 is fixed inside the outer cover 7 by the fixing seat 2 15 and the fixing seat 3 19 to maintain stability. Then, the rotation of the lead screw 14 drives the nut 16 to rise and fall, which in turn drives the lifting plate 17 to move, which in turn drives the lifting column 18 to move, thereby adjusting the height of the bearing platform 1. When the bearing platform 1 is raised and lowered, the guide shaft 8 at the bottom of the bearing platform 1 slides inside the linear bearing 6 to limit the movement and maintain stable adjustment, thus stably adjusting the material.
