Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to a tooling fixture for installing elastic devices. Background Technology

[0002] The elastic device includes a frame, a support unit, a hook, and a spring. The support unit is located inside the frame. One end of the support unit is connected to one end of the frame via the hook, and the other end of the support unit is connected to the other end of the frame via the spring.

[0003] The support unit consists of two crossbars arranged in parallel, with the ends of the steel wires connected to the two crossbars respectively. It can be seen that the support unit has a wire mesh structure, which provides good elasticity when used with the sofa seat frame.

[0004] Currently, the assembly of elastic devices is typically done manually by operators. The assembly process requires applying considerable force to install the springs between the support unit and the frame, and since a single elastic device contains multiple springs, this results in high labor intensity and the assembly quality depends entirely on the operator's experience, making it impossible to fully guarantee the quality of the final product. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a tooling fixture for installing elastic devices that offers high operational efficiency and stability.

[0006] To achieve the above objectives, this utility model can be implemented through the following technical solutions:

[0007] A fixture for installing an elastic device includes a frame, a support unit, a hook, and a spring. The support unit is located inside the frame, with one end connected to one end of the frame via the hook, and the other end connected to the other end of the frame via the spring. The fixture includes a working platform and is characterized by further including a first driving component, a second driving component, a first positioning component, and a second positioning component. The first positioning component, the first driving component, and the second driving component are all fixedly connected to the working platform. The second positioning component is connected to the first driving component and is positioned facing the first. The first driving component can move the second positioning component closer to or further away from the first positioning component. The first positioning component can position one end of the frame, and the second positioning component can support the frame. The second positioning component also has a connecting portion for pre-connecting one end of the spring. The second driving component is located on the working platform between the first and second positioning components, and can push the support unit upwards.

[0008] In the aforementioned tooling fixture for installing the elastic device, the positioning component includes at least two columns fixed to the working platform, with the two columns located parallel to each other on both sides of the working platform.

[0009] In the aforementioned tooling fixture for installing the elastic device, the second positioning component includes a guide rail and a push plate. The guide rail is fixed to the working platform, and the push plate is connected to the guide rail and connected to the first driving component. The upper part of the push plate can support the bottom of the frame.

[0010] In the aforementioned tooling fixture for installing the elastic device, there are two guide rails, and the lower part of the push plate is fixedly connected to a slider that matches and corresponds to the guide rail.

[0011] A limiting plate is detachably connected to the push plate, the lower end of which is connected to the push plate, and the inner side of the push plate can abut against the outer side of the frame.

[0012] In the aforementioned tooling fixture for installing the elastic device, there are two limiting plates, which are located at both ends of the push plate.

[0013] In the aforementioned tooling fixture for installing the elastic device, the connecting part includes a rod-shaped segment one and a rod segment two. The rod segment one is vertically arranged and its lower end is fixedly connected to the push plate. The rod segment two is horizontally arranged and its inner end is fixedly connected to the upper end of the rod segment one. The outer end of the rod segment two is away from the positioning component one and has a recessed positioning hole at its outer end.

[0014] In the aforementioned tooling fixture for installing the elastic device, the positioning hole is a blind hole and the opening end of the positioning hole is located at the upper part of the second rod segment.

[0015] In the aforementioned tooling fixture for installing the elastic device, there are several connecting parts, which are evenly distributed on the push plate between the two limiting plates.

[0016] In the aforementioned tooling fixture for installing the elastic device, the second driving component includes a cylinder and a top plate. The cylinder body is fixedly connected to the working platform, and the top plate is flat and its lower part is fixedly connected to the piston rod of the cylinder.

[0017] Compared with the prior art, the tooling fixture for installing the elastic device can position the frame through positioning component one and positioning component two. At the same time, after the spring is prepositioned and connected between positioning component two and the frame, the driving component one stretches the spring to the set position, and then the driving component two pushes the support unit. The upward-moving support unit will contact the spring, and the spring will disengage from positioning component two after being subjected to the above-mentioned force.

[0018] Since the spring and support unit are aligned at this point, the spring will naturally retract and stably engage with the support unit. It can be seen that in the above process, after pre-connecting the springs to the frame and positioning assembly, this fixture can stably engage multiple springs with the support unit in one go. Clearly, this fixture has high operating efficiency and a high yield rate for the entire elastic device after assembly. Attached Figure Description

[0027] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0028] like Figure 1-6 As shown, the elastic device includes a frame 1, a support unit 2, a hook 3, and a spring 4. The support unit 2 is located inside the frame 1. One end of the support unit 2 is connected to one end inside the frame 1 through the hook 3, and the other end of the support unit 2 is connected to the other end inside the frame 1 through the spring 4.

[0029] The tooling fixture for installing the elastic device includes a working platform 5, and also includes a first drive component 6, a second drive component, a first positioning component, and a second positioning component. The first positioning component, the first drive component 6, and the second drive component are all fixedly connected to the working platform 5. The second positioning component is connected to the first drive component 6 and is positioned opposite to the first positioning component. The first drive component 6 can drive the second positioning component to move closer to or further away from the first positioning component. The first positioning component can position one end of the frame 1, and the second positioning component can support the frame 1. The second positioning component also has a connecting part 12 for pre-connecting one end of the spring 4. The second drive component is located on the working platform 1 between the first positioning component and the second positioning component, and the second drive component can push the support unit upward.

[0030] In the initial state, frame 1 is positioned between positioning component one and positioning component two. At the same time, the two ends of hook 3 are connected to frame 1 and support unit 2 respectively, and the two ends of spring 4 are connected to the connecting part 12 of positioning component two and frame 1 respectively. At this time, spring 4 is not connected to the support unit.

[0031] In this state, the second drive component is at its lowest position. The second drive component is located directly below the support unit 2. After the second drive component applies an upward force to push the support unit 2, the spring 4 is located on top of the support unit. The gradually moving support unit 2 eventually pushes the end of the spring 4 away from the connecting part 12. Then, the spring 4 retracts under its own elastic force and its end is fastened to the support unit 2.

[0032] Since there are several springs 4, during the above-mentioned operation, all springs 4 are simultaneously disengaged from the connecting part 12, and all springs 4 are simultaneously fastened to the support unit 2, thus quickly completing the assembly of the elastic device.

[0033] The positioning component includes at least two columns 8 fixed to the work platform 5, with the two columns 8 located parallel to each other on both sides of the work platform 5.

[0034] Two uprights 8 rest against the inside of the frame 1 to ensure that one end of the frame 1 can be stably connected to the positioning component.

[0035] The second positioning component includes a guide rail 9 and a push plate 10. The guide rail 9 is fixedly connected to the working platform 5, and the push plate 10 is connected to the guide rail and is connected to the first driving component. The upper part of the push plate 10 can support the bottom of the frame 1.

[0036] Under the action of the guide rail 9, the push plate 10 is driven by the first driving component and can move smoothly along the guide rail 9.

[0037] In this embodiment, the driving component is a cylinder. Depending on the actual situation, it is feasible to use a hydraulic cylinder or a linear motor as the driving component.

[0038] There are two guide rails 9, and the lower part of the push plate 10 is fixedly connected to a slider 14 that matches and corresponds to the guide rail 9.

[0039] This structure ensures that the push plate moves smoothly.

[0040] A limiting plate 11 is detachably connected to the push plate 10. The lower end of the limiting plate 11 is connected to the push plate 10, and the inner side of the push plate 10 can abut against the outer side of the frame 1.

[0041] There are two limiting plates 11, which are located at both ends of the push plate 10.

[0042] The limiting plates 11 are located on both sides of the frame 1. This structure ensures the initial position of the frame 1 during installation, simplifying assembly and avoiding the tedious process of searching for its installation position during the installation of the frame 1.

[0043] The connecting part 12 includes a rod-shaped first rod segment 12a and a second rod segment 12b. The first rod segment 12a is vertically arranged and its lower end is fixedly connected to the push plate 10. The second rod segment 12b is horizontally arranged and its inner end is fixedly connected to the upper end of the first rod segment 12a. The outer end of the second rod segment 12b is away from the positioning component and has a recessed positioning hole 12b1 at its outer end.

[0044] Since the positioning hole 12b1 is as far away from the push plate 10 as possible, and one end of the spring 4 is connected to the frame 1, the other end of the spring 4 does not need to be stretched a large distance to be fastened to the connecting part 12.

[0045] After the push plate 10 moves the connecting part 12, the spring 4 is pulled up a large distance in a stable manner.

[0046] After the other end of spring 4 passes the support unit 2, the support unit 2 is pushed upward by the driving member 2. During the upward movement of the support unit 2, the spring 4 is pushed, forcing the other end of spring 4 to detach from the connecting part 12.

[0047] Once the other end of the spring 4 disengages from the connecting part 12, the other end of the spring 4 retracts and is stably fastened to the support unit 2.

[0048] The positioning hole 12b1 is a blind hole and the open end of the positioning hole 12b1 is located on the upper part of the second rod segment 12b.

[0049] This structure ensures that when spring 4 is pushed, the other end of spring 4 can stably detach from the connecting part 12.

[0050] The number of connecting parts 12 is several, and the several connecting parts 12 are evenly distributed on the push plate 10 between the two limiting plates 11.

[0051] The connecting part 12 corresponds one-to-one with the spring 4 in the elastic device, so that all the springs 4 in the frame 1 can be assembled at once.

[0052] The second driving component includes a cylinder 7 and a top plate 13. The cylinder body of the cylinder 7 is fixedly connected to the working platform 5, and the top plate 13 is flat and the lower part of the top plate 13 is fixedly connected to the piston rod of the cylinder 7.

[0053] The top plate 13 is in contact with the support unit 2, which prevents the support unit 2 from being deformed or even damaged due to local stress, effectively improving its stability and not affecting the yield of the finished elastic device.

[0054] The tooling fixture for installing the elastic device can position the frame through positioning component one and positioning component two. At the same time, after the spring is pre-positioned and connected between positioning component two and the frame, the driving component one stretches the spring to the set position, and then the driving component two pushes the support unit. The upward-moving support unit will contact the spring, and the spring will disengage from positioning component two after being subjected to the above-mentioned force.

[0055] Since the spring and support unit are aligned at this point, the spring will naturally retract and stably engage with the support unit. It can be seen that in the above process, after pre-connecting the springs to the frame and positioning assembly, this fixture can stably engage multiple springs with the support unit in one go. Clearly, this fixture has high operating efficiency and a high yield rate for the entire elastic device after assembly.

[0056] In this embodiment, the support unit is existing technology, and the specific technical solutions of the existing technology are also disclosed in the background section. Therefore, it will not be described in detail in this embodiment.

[0057] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0058] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
