Description

Technical Field

[0001] This utility model relates to the field of seat manufacturing technology, and in particular to a four-way leg rest assembly fixture. Background Technology

[0002] In the field of seat manufacturing, four-way leg rests are crucial components for enhancing seat comfort, and their assembly precision and efficiency directly impact the overall quality and production efficiency of the seat. Traditional four-way leg rest assembly processes often rely on manual operation, requiring workers to manually place and secure multiple components one by one before assembly. However, this method has several drawbacks:

[0003] On the one hand, manual operation makes it difficult to ensure the accuracy and stability of component placement, which can easily lead to component misalignment or insecure fixing, resulting in inconsistent assembly quality and increased defect rate. On the other hand, repeated adjustments to component positions also affect assembly efficiency.

[0004] On the other hand, existing assembly fixtures are not effective enough in placing and fixing parts, and the operation of fixing parts is cumbersome, which leads to low efficiency of workers in placing and fixing parts, making it difficult to meet the needs of large-scale production. Moreover, long-term manual operation can easily cause worker fatigue, further affecting assembly quality and efficiency.

[0005] To address the aforementioned issues, this utility model document proposes a four-way leg support assembly fixture. Utility Model Content

[0006] The purpose of this utility model is to solve the shortcomings of existing technology, such as the difficulty in ensuring accurate placement and quick fixation of parts by traditional assembly fixtures, cumbersome operation, low assembly efficiency, and difficulty in meeting the needs of large-scale production, and to propose a four-way leg support assembly fixture.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A four-way leg support assembly fixture, comprising:

[0009] The first assembly fixture and the second assembly fixture, the first assembly fixture includes a first mounting plate, the top of the first mounting plate is provided with a first clamping component and a second clamping component, the first assembly fixture is used to place and fix multiple parts to be assembled into a four-way leg support motor assembly, so as to complete the assembly of the four-way leg support motor assembly.

[0010] The second assembly fixture includes a second mounting plate, the top of which is provided with two third clamping components and a pressing component. The second assembly fixture is used to place and fix the four-way leg support motor assembly and other parts to be used in order to complete the assembly of the four-way leg support slide rail assembly.

[0011] In one possible design, a fixed platform is fixedly mounted on the top of the first mounting plate, and two first positioning seats are fixedly mounted on the top of the fixed platform. Each of the two first positioning seats has a positioning protrusion fixedly mounted on its top. The first positioning seats and positioning protrusions are used to place and position the parts. The second clamping assembly is fixedly disposed on the top of the fixed platform and is used to press and fix the parts placed on the fixed platform.

[0012] In one possible design, two second mounting brackets are fixedly mounted on the top of the first mounting plate, and a first mounting bracket is fixedly mounted on the top of the first mounting plate. The first mounting bracket is located on the side of the two second mounting brackets away from the fixed platform. The first mounting bracket and the two second mounting brackets are used to place the corresponding parts. The first clamping assembly is fixedly mounted on one side of the fixed platform. The first clamping assembly cooperates with one of the second mounting brackets to press and fix the corresponding parts.

[0013] In one possible design, two second positioning seats are fixedly installed on the top of the second mounting plate, and the top of the two second positioning seats is provided with corresponding positioning cones. The two second positioning seats are used to complete the positioning and placement of the corresponding parts. Two third mounting frames are fixedly installed on the top of the second mounting plate. The two third clamping components are located on one side of the adjacent third mounting frame. The two third clamping components are fixedly installed on the top of the second mounting plate. The two third clamping components cooperate with the adjacent third mounting frame to complete the clamping and fixing of the corresponding parts.

[0014] In one possible design, a fixing bracket is fixedly mounted on the top of the second mounting plate, and a fourth mounting bracket is fixedly mounted on the top of the fixing bracket. The pressing assembly is disposed on one side of the fixing bracket, and the pressing assembly includes a first cylinder fixedly mounted on one side of the fixing bracket. A T-shaped pressing block is fixedly mounted on the top of the piston rod of the first cylinder. One of the protrusions of the T-shaped pressing block cooperates with the top of the fourth mounting bracket to complete the pressing and fixing of the corresponding parts.

[0015] In one possible design, the first clamping assembly, the second clamping assembly, and the two third clamping assemblies all have the same structure, each consisting of a second cylinder, a fixed base, a connecting bracket, a rotating head, and a pressing plate. The fixed base is fixedly installed on the top of the corresponding second cylinder. One end of the piston rod of the second cylinder passes through the corresponding fixed base and is fixedly connected to the rotating head. The connecting bracket is rotatably installed on the top of the fixed base. One end of the pressing plate is rotatably connected to the rotating head, and the outer wall of the pressing plate is rotatably connected to the other end of the connecting bracket to achieve the lifting and lowering of one end of the pressing plate. A pressing block is fixedly installed at the bottom of the pressing plate near the other end. The pressing block cooperates with the pressing plate to press and fix the corresponding parts.

[0016] In this application, during operation, multiple components to be assembled into a four-way leg support motor assembly are placed at corresponding positions on the first mounting plate. Some components are placed on two first positioning seats on the fixed platform, with positioning protrusions on the top of the first positioning seats providing initial positioning. Other components are placed on a first mounting frame and two second mounting frames. Then, the first and second clamping assemblies are activated: taking the first clamping assembly as an example, the piston rod of the second cylinder retracts, causing the rotating head to move downwards. The rotating head causes the pressing plate to rotate around the connecting bracket, raising one end of the pressing plate. When the component is in place, the piston rod of the second cylinder extends, causing the pressing plate to fall. The pressing block at the bottom of the pressing plate presses and fixes the component. The second clamping assembly operates in the same way as the first clamping assembly, ensuring rapid and stable placement of the components on the fixed platform.

[0017] After the parts are fixed, the workers assemble the parts fixed on the first assembly fixture according to the assembly process requirements, and the assembly of the four-way leg support motor assembly can be completed.

[0018] After the four-way leg support motor assembly is assembled, the worker can place the four-way leg support motor assembly and other parts to be used in their respective positions on the second mounting plate. Some parts are placed on the two second positioning seats, and the positioning cones on the top of the second positioning seats can position the parts. Other parts are placed on the two third mounting frames. Then, the two third clamping components and the pressing component are activated. The third clamping components work in the same way as the first clamping components. The second cylinder drives the pressing plate to clamp and fix the parts placed on the third mounting frames. In the pressing component, the piston rod of the first cylinder retracts, causing the T-shaped pressing block to move downward. One of the protrusions of the T-shaped pressing block contacts the part on the top of the fourth mounting frame and applies pressure to complete the pressing and fixing of the part.

[0019] After the components are fixed, the worker can assemble the four-way leg support motor assembly with other components fixed on the second assembly fixture to complete the assembly of the four-way leg support slide rail assembly.

[0020] Beneficial effects: The four-way leg support assembly fixture of this utility model integrates the functions of placing, fixing and assembling multiple parts. Workers only need to place the parts in the corresponding positions according to the operation process, and the fixture will automatically complete the fixing and assembly, which greatly reduces the time and labor intensity of manual operation and improves the assembly efficiency. The first assembly fixture is used to place and fix multiple parts to be assembled into a four-way leg support motor assembly, and the second assembly fixture is used to place and fix the four-way leg support motor assembly and other parts to be used, so as to complete the assembly of the four-way leg support slide rail assembly. It can meet the needs of different assembly stages of the four-way leg support and has strong versatility and adaptability.

[0021] In this utility model, the four-way leg support assembly fixture, by setting positioning components such as a first positioning seat, a positioning protrusion, and a second positioning seat, can accurately position and place parts, ensure the positional accuracy of parts during the assembly process, reduce assembly errors caused by positional offset, and improve assembly quality.

[0022] In this utility model, the four-way leg support assembly fixture, the first clamping assembly, the second clamping assembly and the third clamping assembly all adopt the same structure of cylinder driving the pressing plate to rotate, and the pressing assembly adopts the structure of cylinder driving the T-shaped pressing plate to move up and down. They can all apply stable pressure to the parts, which can ensure that the parts will not loosen or shift during the assembly process, and ensure the stability and reliability of the assembly.

[0023] In this invention, the four-way leg support assembly fixture integrates the functions of component placement, fixing, and assembly. Workers can use two fixtures sequentially according to the process to quickly complete the fixing and assembly of components, reducing manual operation time and labor intensity, and improving assembly efficiency. This fixture can meet the needs of different assembly stages of the four-way leg support, and has strong versatility and adaptability. By setting positioning components, it can accurately position and place components, reduce assembly errors, improve assembly quality, and effectively ensure the stability and reliability of the four-way leg support assembly.

[0039] Example 2: Reference Figure 2 , 3 4. Improvement based on Example 1: A four-way leg rest assembly fixture, which is applied to the field of seat manufacturing technology;

[0040] In this embodiment, the first clamping assembly 8, the second clamping assembly 12, and the two third clamping assemblies 16 have the same structure, each consisting of a second cylinder 21, a fixed base 22, a connecting bracket 23, a rotating head 24, and a pressing plate 25.

[0041] The fixed base 22 is fixedly installed on the top of the corresponding second cylinder 21. One end of the piston rod of the second cylinder 21 passes through the fixed base 22 and is fixedly connected to the rotating head 24. The connecting bracket 23 is rotatably installed on the top of the fixed base 22. One end of the pressing plate 25 is rotatably connected to the rotating head 24, and the outer wall of the pressing plate 25 is rotatably connected to the other end of the connecting bracket 23. When the piston rod of the second cylinder 21 extends or retracts, it drives the rotating head 24 to move, thereby lifting and lowering one end of the pressing plate 25 through the connecting bracket 23. A pressing block 26 is fixedly installed at the bottom of the pressing plate 25 near the other end. The pressing block cooperates with the pressing plate 25 to press and fix the corresponding parts.

[0042] However, as is well known to those skilled in the art, the working principles and wiring methods of the first cylinder 19 and the second cylinder 21 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0043] The working principle and usage process of this technical solution are as follows: During operation, multiple components to be assembled into a four-way leg support motor assembly 1 are placed in corresponding positions on the first mounting plate 5; among them, some components are placed on two first positioning seats 10 on the fixed platform 9, and the positioning protrusions 11 on the top of the first positioning seats 10 can perform preliminary positioning of the components; other components are placed on the first mounting frame 6 and two second mounting frames 7 respectively; then the first clamping assembly 8 and the second clamping assembly 12 are activated: taking the first clamping assembly 8 as an example, the piston rod of the second cylinder 21 retracts, driving the rotating head 24 to move downward, and the rotating head 24 drives the pressing plate 25 to rotate around the connecting bracket 23, so that one end of the pressing plate 25 rises. When the component is placed in place, the piston rod of the second cylinder 21 extends, driving the pressing plate 25 to fall, and the pressing block 26 at the bottom of the pressing plate 25 can press and fix the component; the working mode of the second clamping assembly 12 is the same as that of the first clamping assembly 8, which can ensure the rapid and stable placement of the components on the fixed platform 9;

[0044] After the parts are fixed, the workers assemble the parts fixed on the first assembly fixture 3 according to the assembly process requirements, and the assembly of the four-way leg support motor assembly 1 can be completed.

[0045] After the four-way leg support motor assembly 1 is assembled, the worker can place the four-way leg support motor assembly 1 and other parts to be used in the corresponding positions on the second mounting plate 13. Among them, some parts are placed on the two second positioning seats 14, and the positioning cones on the top of the second positioning seats 14 can position the parts; other parts are placed on the two third mounting frames 15. Then, the two third clamping assemblies 16 and the pressing assembly are activated. The third clamping assembly 16 works in the same way as the first clamping assembly 8. The second cylinder 21 drives the pressing plate 25 to clamp and fix the parts placed on the third mounting frame 15. In the pressing assembly, the piston rod of the first cylinder 19 retracts, driving the T-shaped pressing block 20 to move downward. One of the protrusions of the T-shaped pressing block 20 contacts the part on the top of the fourth mounting frame 18 and applies pressure to complete the pressing and fixing of the part.

[0046] After the components are fixed, the worker can assemble the four-way leg support motor assembly 1 with other components fixed on the second assembly fixture 4 to complete the assembly of the four-way leg support slide rail assembly 2.
