Description

Technical Field

[0001] The present application relates to the technical field of production and processing of disassembly and assembly legs, and in particular to a disassembly and assembly leg material removal jig and a material removal device. Background Art

[0002] A detachable foot assembly is a furniture component designed for easy disassembly and installation, primarily used as a support structure for furniture such as chairs. It typically consists of a central base and several tubular detachable feet that extend from front to back. The central base includes a cylindrical mounting sleeve and several hollow tubular mounting feet. The detachable foot sleeves are attached to the other ends of the mounting feet and are removably fixed to them. This structure makes the detachable feet easy to assemble and disassemble, and facilitates transportation.

[0003] In the existing technology, in order to achieve the picking and placing of inserts and workpieces, the following methods are usually adopted: First, use two independent sets of fixtures to handle the inserts and workpieces respectively. Although this method is simple, it requires frequent replacement of fixtures in actual operation, which increases the complexity and time cost of the operation; second, manually adjust the position of the fixture so that it can handle the inserts and workpieces in sequence. Although this method does not require replacement of fixtures, the manual adjustment process is cumbersome and prone to errors, affecting production efficiency; third, use multi-station automated equipment, and complete the picking and placing of inserts and workpieces in different stations in sequence through programmed control equipment. Although this method improves the degree of automation, it is not suitable for use by small and medium-sized enterprises due to the large size of the equipment, large footprint, and high investment cost. Utility Model Content

[0004] In view of this, the present application provides a disassembly and assembly foot material removal fixture and a material removal device, which have a compact structure and improve processing efficiency.

[0005] In the first aspect, the present application provides a disassembly and assembly foot material picking fixture for picking up and placing inserts and workpieces. The material picking fixture includes a main body, an insert clamp and a workpiece clamp. The insert clamp and the workpiece clamp are arranged on the front and back sides of the main body, and a rotating part is provided on the side of the main body.

[0006] By adopting the technical solution of this application, the design of the main body, insert fixture, and workpiece fixture allows inserts and workpieces to be placed and retrieved from different sides (front and back). This design eliminates the tedious steps required by traditional methods to handle inserts and workpieces separately, which may require fixture replacement or repositioning, thereby greatly improving operational efficiency. By locating the insert fixture and workpiece fixture on the front and back of the main body, respectively, the jig maintains functionality while achieving a compact structure. This design allows the jig to efficiently handle two different types of components while occupying a small space, improving space utilization. A rotating member on the side of the main body allows the entire jig to be easily rotated to adapt to different operational requirements or space constraints. This flexibility not only improves operational convenience but also enables the jig to be used at multiple angles, further expanding its application scenarios. Through its ingenious design and combination, this disassembly and retrieving jig achieves multiple technical benefits, including efficient assembly and disassembly, convenient operation, a compact structure, versatility, and improved production efficiency and quality.

[0007] In some embodiments, the insert clamp includes a first driving member and at least two clamping jaws, and the first driving member drives the at least two clamping jaws to move toward or away from each other.

[0008] By adopting the above technical solution, the insert clamp uses at least two clamping jaws, which are driven toward or away from each other by a first driving member, achieving precise clamping of the insert. This design ensures stability and accuracy during the insert placement process, avoiding damage or misalignment caused by unstable clamping.

[0009] In some embodiments, grooves are provided on opposite surfaces of the clamping jaws, and the grooves of different clamping jaws have support surfaces located in the same plane.

[0010] By adopting the above technical solution, it is possible to ensure that the insert is evenly and stably supported during the clamping process. This uniform distribution of support force helps prevent the insert from sliding or tilting during the clamping process, thereby improving the stability and accuracy of the clamping. Because the support surfaces of the grooves are located in the same plane, the clamping jaws can more accurately control the position of the clamping point when clamping the insert. This precise control helps improve the positioning accuracy of the insert during the pick-and-place process, ensuring that the insert can be accurately placed in the target position. The design of the grooves can also reduce the area of ​​direct contact between the clamping jaws and the insert, thereby reducing the risk of damage to the insert surface during the clamping process. This is particularly important for applications where the integrity of the insert surface needs to be maintained. By rationally designing the shape and depth of the grooves, the distribution of the clamping force on the insert can be optimized. This optimized clamping force distribution helps reduce deformation and damage to the insert during the clamping process, while improving the reliability and stability of the clamping.

[0011] In some embodiments, under the drive of the first driving member, the at least two clamping jaws have a free position, a clamping position and a pushing position, and the distance between the at least two clamping jaws is the largest in the free position and the smallest in the pushing position.

[0012] By adopting the above technical solution, the jaws have three working states: free position, clamping position, and pushing position, which makes the fixture more flexible during the insert processing process. In the free position, the distance between the jaws is the largest, facilitating the placement and removal of the insert; in the clamping position, the jaws are moderately close to clamp the insert; in the pushing position, the distance between the jaws is the smallest, used to stably push the insert to the target position. This multi-state design allows the fixture to adapt to different operational requirements. The multi-state design and precise control of the jaws enable the fixture to complete the insertion, placement, and pushing operations of the insert more efficiently. This efficient operating mode helps improve production efficiency and reduce waiting time and waste during the production process.

[0013] In some embodiments, the rotation axis of the rotating member is perpendicular to the side surface and parallel to the front surface and the rear surface.

[0014] By implementing this technical solution, the compact layout enables efficient jig operation within a limited work area, improving overall production line efficiency. The jig can be easily switched between the front and back sides by rotating the rotator, streamlining the operation process. Operators can access inserts and workpieces without changing jigs or adjusting their positions, improving operational convenience and efficiency.

[0015] In some embodiments, the workpiece clamp includes a second driving member fixed to the reverse surface and at least two clamping plates connected to a driving end of the second driving member, and the second driving member drives the at least two clamping plates to move toward or away from each other.

[0016] By adopting this technical solution, the workpiece clamp achieves precise clamping of the workpiece by using a second drive member to drive at least two clamping plates toward or away from each other. This design ensures stability and accuracy during the workpiece placement process, avoiding damage or misalignment caused by unstable clamping.

[0017] In some embodiments, the reverse side is provided with at least four workpiece clamps, and the opposite side of the clamping plate is provided with a soft pad.

[0018] By adopting this technical solution, the opposing sides of the clamping plates are padded. This design reduces friction and impact when the clamping plates come into direct contact with the workpiece, thereby reducing the risk of damage to the workpiece surface and lowering fixture maintenance costs. The collaborative operation of multiple workpiece fixtures can significantly improve production efficiency. On a single production line, multiple workpieces can be processed simultaneously, reducing waiting time and production cycle time. Furthermore, due to stable and accurate clamping, rework and downtime caused by workpiece misalignment or damage can be reduced, further improving production efficiency.

[0019] In some embodiments, avoidance holes are provided at positions of the reverse surface between the at least four workpiece fixtures.

[0020] By adopting this technical solution, the design of the avoidance hole prevents the nozzle material connecting the workpieces from interfering with the workpiece fixture during the clamping process, and also serves as a preliminary positioning function. This helps ensure that the workpiece fixture can accurately clamp the workpiece itself without being obstructed by the nozzle material, thereby improving clamping precision and stability. The presence of the avoidance hole allows the workpiece fixture to clamp and release the workpiece more smoothly, reducing operational obstacles caused by interference. This helps to accelerate production, improve production efficiency, and reduce downtime caused by improper operation.

[0021] In a second aspect, the present application provides a material picking device, comprising a rotating drive member and the disassembly and assembly foot material picking fixture of the first aspect.

[0022] By adopting the above technical solution, the rotary drive member is rotatably connected to the reclaiming jig via the rotating member, which can drive the reclaiming jig to rotate along the axis of the rotating member. This design enables the reclaiming jig to perform reclaiming and unloading operations in different positions or directions, improving the flexibility and efficiency of the reclaiming device.

[0023] In some embodiments, the rotary drive member is rotatably connected to the material picking fixture via the rotating member, and the rotary drive member drives the material picking fixture to rotate along the axis of the rotating member.

[0024] By adopting this technical solution, the rotary drive can precisely control the rotation angle and speed of the reclaiming fixture, thereby achieving fast and accurate reclaiming operations. The modular design of the reclaiming device allows for individual replacement or upgrade of reclaiming fixtures, reducing maintenance costs and improving the efficiency of switching between reclaiming fixtures of different specifications.

[0025] In summary, this application has at least one of the following beneficial technical effects:

[0026] 1. The disassembly and assembly foot reclaiming fixture realizes the technical effects of efficient disassembly and assembly, convenient operation, compact structure, multi-function and improved production efficiency and quality.

[0027] 2. The modular design of the reclaiming device allows for individual replacement or upgrade of reclaiming fixtures, reducing maintenance costs and improving the efficiency of switching between reclaiming fixtures of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0042] Example 1

[0043] See also Figures 1-6 The disassembly and assembly foot material removal jig 100 provided in an embodiment of the present application includes a main body 1, an insert fixture 2 and a workpiece fixture 3. The insert fixture 2 and the workpiece fixture 3 are arranged on the front and back sides of the main body 1, and a rotating part 4 is provided on the side of the main body 1. A control mechanism 5 is provided in the main body 1 to control the coordinated operation of the insert fixture 2 and the workpiece fixture 3. This design allows the insert-nut 61 and the workpiece-disassembly and assembly foot 6 to be taken and placed on different sides (front and back), avoiding the tedious steps of replacing the jig or adjusting the position in the traditional method, thereby greatly improving the operating efficiency. By arranging the insert fixture 2 and the workpiece fixture 3 on the front and back sides of the main body 1 respectively, the jig achieves a compact structure while maintaining functionality. This design allows the jig to efficiently handle two different types of components while occupying a smaller space, thereby improving space utilization. The rotating part 4 provided on the side of the main body 1 allows the entire jig to be easily rotated to adapt to different operating requirements or space limitations. This flexibility not only improves the convenience of operation, but also enables the jig to be used at multiple angles, further expanding its application scenarios.

[0044] See also Figure 1-Figure 3Four sets of insert fixtures 2 are located on the front of the main body 1. Each of these three jaws 22 forms a triangular layout to enhance clamping stability. Four sets of workpiece fixtures 3 are located on the back of the main body 1. Each set of workpiece fixtures 3 has two opposing plates 32, improving uniformity and reliability of clamping. This optimized design makes the fixture more stable and reliable when handling inserts and workpieces, reduces damage or misalignment caused by unstable clamping, increases the number of inserts and workpieces that can be placed and retrieved at one time, and improves production efficiency. Each set of insert fixtures 2 includes a first drive member 21 and three jaws 22. The first drive member 21 can be a pneumatic cylinder, electric motor, or other similar drive device, which drives the three jaws 22 toward or away from each other. The jaws 22 can be made of metal, hard plastic, or other materials, depending on the material of the insert and the required clamping force. The shape of the jaws 22 can be designed based on the specific shape of the insert. For example, it can be round, square, or other special shapes to ensure stable and accurate clamping. In this embodiment, the jaws 22 are L-shaped.

[0045] The rotating part 4 provided on the side of the main body 1 can be a rotating shaft fixedly connected to the main body 1, and its rotation axis is perpendicular to the side and parallel to the front and back surfaces. The rotating part 4 can also be a gear, worm gear, etc. fixedly connected to the main body 1, and the driving mechanism drives the main body 1 to rotate by driving the gear or turbine. This compact spatial layout enables the jig to operate efficiently in a limited working area, improving the overall efficiency of the production line. By rotating the rotating part 4, the jig can be easily switched between the front and back surfaces, thereby simplifying the operating process. The operator can perform the pick-and-place operations of the inserts and workpieces without changing the jig or adjusting the position, which improves the convenience and efficiency of the operation.

[0046] Four groups of workpiece clamps 3 are provided on the reverse side of the main body 1. The workpiece clamps 3 include a second driving member 31 fixed to the reverse side and at least two clamps 32 connected to the driving end of the second driving member 31. The second driving member 31 can be a cylinder, an electric motor, etc., which is used to drive the two clamps 32 to move closer to or away from each other to pick up and place the workpiece. The material of the clamps 32 can be selected from metal, hard plastic, etc., depending on the material of the workpiece and the required clamping force. The shape of the clamps 32 can be designed according to the specific shape of the workpiece. For example, it can be round, square or other special shapes to ensure the stability and accuracy of the clamping. A soft pad is provided on the opposite side of the clamps 32. The soft pad can be made of soft materials such as rubber and silicone to reduce the friction and impact when the clamps 32 are in direct contact with the workpiece, reduce the risk of damage to the workpiece surface, and reduce the maintenance cost of the fixture.

[0047] Four sets of workpiece clamps 3 are located on the reverse side. This design significantly improves production efficiency because multiple workpiece clamps 3 can work together to handle multiple workpieces simultaneously, reducing waiting time and production cycle time. Due to the stable and accurate clamping, rework and downtime caused by workpiece misalignment or damage can be reduced, further improving production efficiency.

[0048] See also Figure 2 On the reverse side, between the four sets of workpiece clamps 3, there is a clearance hole 11. The design of the clearance hole 11 prevents the nozzle material connecting the workpieces from interfering with the workpiece clamps 3 during the clamping process, and also serves as a preliminary positioning function. This helps ensure that the workpiece clamps 3 can accurately clamp the workpiece itself without being obstructed by the nozzle material, thereby improving the clamping accuracy and stability. Due to the presence of the clearance hole 11, the workpiece clamps 3 can clamp and release the workpiece more smoothly, reducing operational obstacles caused by interference, speeding up the production rhythm, improving production efficiency, and reducing downtime caused by improper operation.

[0049] The insert fixture 2 and workpiece fixture 3 can use different drive methods. The first drive element 21 of the insert fixture 2 is hydraulically driven, while the second drive element 31 of the workpiece fixture 3 is pneumatically driven. The advantage of hydraulic drive is its greater strength, making it suitable for handling heavier or larger inserts. Pneumatic drive offers greater flexibility and a faster response, making it suitable for handling lightweight or delicate workpieces. This drive method can be adjusted based on the specific application scenario to achieve the optimal clamping effect.

[0050] Specifically, the hydraulic drive system of the insert fixture 2 includes a hydraulic pump, an oil tank, oil pipes, and a hydraulic cylinder. The hydraulic pump transfers oil from the tank via the oil pipes to the hydraulic cylinder, moving the piston rod, which in turn moves the jaws 22 toward or away from each other. The hydraulic system's pressure can be controlled by a regulating valve to accommodate inserts of varying sizes and weights. The hydraulic drive system is characterized by its high power, stability, and reliability, making it particularly suitable for handling large or heavy inserts.

[0051] The pneumatic drive system for the workpiece clamp 3 comprises an air source, air pipes, and an air cylinder. The air source provides compressed air, which is delivered to the air cylinder via the air pipe. This moves the piston rod, which in turn moves the clamping plates 32 toward or away from each other. The pneumatic drive system features fast response and high flexibility, making it particularly suitable for handling lightweight or delicate workpieces. The pressure of the pneumatic system can be controlled by a regulating valve to accommodate workpieces of varying sizes and thicknesses.

[0052] By choosing different drive modes, the insert fixture 2 and workpiece fixture 3 can be better adapted to their respective application scenarios. Hydraulic drive offers strong force, stability, and reliability, making it particularly suitable for handling larger or heavier inserts; while pneumatic drive offers fast response and high flexibility, making it particularly suitable for handling lightweight or delicate workpieces. This drive mode can be adjusted to the specific application requirements to achieve the optimal clamping effect. The overall design ensures efficient and precise operation while also providing high reliability and durability, making it suitable for a variety of production environments.

[0053] See also Figure 3 The two clamping plates 32 of each set of workpiece clamps 3 move closer to each other to clamp the assembly and disassembly legs 6 for transportation, and the two clamping plates 32 move away from each other to place the assembly and disassembly legs 6. Similarly, the three clamping jaws 22 of each set of insert clamps 2 move closer to the center to clamp the nut 61 insert, and the three clamping jaws 22 move away from the center to release the nut 61 from the clamping jaws 22 and place it.

[0054] See also Figure 4-Figure 6 Driven by the first driving member 21, the clamping jaws 22 have three working states: free position, gripping position, and pushing position. This multi-state design makes the fixture more flexible during the insert processing process, can adapt to different operating requirements, and improve production efficiency.

[0055] See also Figure 4 In the free position, the distance between the jaws 22 is maximized, facilitating the insertion and removal of inserts. Grooves 221 are located on the opposing surfaces of the jaws 22. The grooves 221 of different jaws 22 share a common support surface, ensuring uniform and stable support for the insert during clamping, preventing slippage or tilting and improving clamping stability and accuracy. The depth and width of the grooves 221 can be adjusted based on the actual size of the insert to ensure optimal clamping.

[0056] See also Figure 5 When in the clamping position, the clamping jaws 22 are appropriately close to clamp the nut insert, and the head of the nut insert is located in the groove 221.

[0057] See also Figure 6 When in the pushing position, the three clamping jaws 22 are close to each other, and the distance between the three clamping jaws 22 is the smallest, which makes it easier for the end portion to push the end face of the insert and stably push the insert to the target position.

[0058] The working principle of this embodiment is as follows: By combining the main body 1, insert fixture 2, and workpiece fixture 3, inserts and workpieces can be placed and retrieved from different sides (front and back). This design eliminates the tedious steps required to replace fixtures or adjust their positions in traditional methods, significantly improving operational efficiency. By placing the insert fixture 2 and workpiece fixture 3 on the front and back of the main body 1, respectively, the jig maintains functionality while achieving a compact structure. This design allows the jig to efficiently handle two different types of components while occupying a small space, improving space utilization. The rotating member 4 on the side of the main body 1 allows the entire jig to be easily rotated to adapt to different operating requirements or space constraints. This flexibility not only improves operational convenience but also enables the jig to be used at multiple angles, further expanding its application scenarios. The rational design of the shape, material, and structure of the jaws 22 and clamping plate 32, as well as the provision of the groove 221 and cushioning, ensures stability and accuracy during the placement of inserts and workpieces, preventing damage or misalignment caused by unstable clamping. The overall design ensures that the fixture has high reliability and durability while ensuring efficient and precise operation, making it suitable for various production environments.

[0060] This embodiment provides a retrieving device. In this embodiment, a rotary drive member is added, which is a robotic arm 200. The robotic arm 200 is rotatably connected to the retrieving fixture 100 via a rotating member 4, and can drive the retrieving fixture 100 to rotate along the axis of the rotating member 4. This design enables the retrieving fixture 100 to perform retrieving and unloading operations on workpieces and inserts at different workstations or directions, thereby improving the flexibility and efficiency of the retrieving device.

[0061] Specifically, the robotic arm 200 can precisely control the rotation angle and speed of the retrieving fixture 100, enabling fast and accurate retrieving operations. The modular design of the retrieving device allows for individual replacement or upgrades of the retrieving fixture 100, reducing maintenance costs and improving the efficiency of switching between retrieving fixtures 100 of different specifications.

[0062] The implementation principle of this embodiment is as follows: by adding a robotic arm 200, the material picking fixture 100 can perform material picking and unloading operations at different workstations or directions, thereby improving the flexibility and efficiency of the material picking device. The rotary drive member can accurately control the rotation angle and speed of the material picking fixture 100, thereby achieving fast and accurate material picking operations. The modular design of the material picking device allows the material picking fixture 100 to be replaced or upgraded individually, reducing maintenance costs and improving the switching efficiency of material picking fixtures 100 of different specifications. The overall design ensures that the material picking device has high reliability and durability while ensuring efficient and precise operation, and is suitable for various production environments.
