Description

Technical Field

[0001] This utility model relates to the field of seat technology, specifically to a frame auxiliary panel tooling. Background Technology

[0002] During the processing of the chair back, in order to attach the sponge and fabric cover to the frame, cardboard needs to be riveted to the frame. Several riveting holes are made around the cardboard and the frame. The workers need to bend the cardboard to fit the frame and align the riveting holes on the frame and cardboard. Then, they use a rivet gun to drive rivets into the rivet holes to fix the frame and cardboard together.

[0003] However, cardboard is a relatively hard material. If workers manually press the cardboard, they not only need to exert a lot of force to bend it to fit the frame, but also need to keep the rivet holes on the frame and cardboard aligned while driving in the rivets. This not only requires a lot of work, but it is also difficult for a single person to align the rivet holes on the frame and cardboard. As a result, it takes a long time to press a single frame and the work efficiency is low. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a frame-assisted panel fitting fixture. The frame-assisted panel fitting fixture connects the rivet holes on the frame and the cardboard together through at least two positioning protrusions, so that when the cardboard is bent, the remaining rivet holes on the cardboard and the frame can be aligned, and the positioning operation is simple. In addition, the lower pressure plate is automatically moved downward by the first drive mechanism and bends the cardboard to fit the frame, so the operator does not need to manually bend the cardboard, reducing the workload. The operator only needs to align the rivet holes and drive in the rivets to complete the assembly work, which is relatively easy and effectively improves work efficiency.

[0005] The effect of this utility model is achieved as follows: This application provides a frame-assisted panel tooling, including a worktable and a support frame disposed above the worktable. A support assembly is disposed on the worktable, configured to support and fix a frame and a cardboard. The support assembly includes at least two positioning protrusions, which are configured to pass through rivet holes on the frame and the cardboard, thereby fixing the frame and the cardboard to the support assembly. A clamping assembly is disposed on the support frame, including a lower pressure plate, which is configured as a curved panel with an arc consistent with that of the frame. The lower pressure plate is movably connected to the support frame through a first driving mechanism. The frame-assisted panel fixture includes a switchable initial state and a working state. In the initial state, the lower pressure plate is in a higher position, and the user can align the rivet holes on the frame and cardboard with the positioning protrusions and insert them to fix the frame and cardboard to the support assembly. In the working state, the first drive mechanism drives the lower pressure plate to move downward until the cardboard is bent and pressed against the frame.

[0006] Furthermore, the support component is provided with two symmetrical positioning protrusions. The two positioning protrusions are aligned with the frame and the two riveting holes on the front and rear sides of the cardboard. The structure is simple and allows the cardboard to be placed stably on the frame, making it relatively stable.

[0007] Furthermore, the support component includes a second drive mechanism configured to drive the positioning protrusion to move up and down. In operation, when the cardboard is pressed against the frame, the second drive mechanism drives the positioning protrusion to move downwards, causing it to avoid the rivet holes on the frame and the cardboard. This allows workers to install rivets at the corresponding rivet holes on the positioning protrusion, further improving the ease of operation.

[0008] Furthermore, the support assembly includes a chassis, with a positioning protrusion fixed to the top of the chassis. The chassis is connected to the worktable via a first rotating mechanism, allowing the chassis to rotate horizontally relative to the worktable. The lower pressure plate is connected to the first drive mechanism via a second rotating mechanism, allowing the lower pressure plate to rotate horizontally relative to the support frame. When the lower pressure plate presses the cardboard against the frame, the rotation of the lower pressure plate and the chassis allows the operator to rotate the frame and the cardboard as a whole, thereby performing riveting operations on the rivet holes around the frame and the cardboard, further improving the ease of riveting operations.

[0009] Furthermore, in the initial state, when the chassis rotates to a preset angle, the first rotating mechanism stops rotating, fixing the chassis in its current position; when the lower pressure plate rotates to a preset angle, the second rotating mechanism stops rotating, fixing the lower pressure plate in its current position; when both the chassis and the lower pressure plate rotate to the preset angle, the curved surface of the lower pressure plate aligns with the frame on the support assembly. At this time, the frame auxiliary panel fixture can be switched to working mode to press the cardboard, making the positioning operation more convenient.

[0010] Furthermore, a first sensing mechanism is provided between the chassis and the worktable, comprising a first sensor mounted on the worktable and a first receiver mounted on the bottom of the chassis; a second sensing mechanism is provided between the lower pressure plate and the support frame, comprising a second sensor mounted on the support frame and a second receiver mounted on the lower pressure plate; initially, when the chassis rotates to a preset angle, the first sensor aligns with the first receiver, and the first rotation mechanism stops rotating; when the lower pressure plate rotates to a preset angle, the second sensor aligns with the second receiver, and the second rotation mechanism stops rotating. This simplifies the positioning operation and ensures higher accuracy, guaranteeing that the curved surface of the lower pressure plate aligns with the frame on the support assembly after positioning.

[0011] Furthermore, in the initial state, when both the chassis and the lower pressure plate have rotated to a preset angle, the frame-assisted paneling fixture automatically switches to the working state, and the first drive mechanism drives the lower pressure plate to move downwards. This eliminates the need for manual control of the frame-assisted paneling fixture to switch states after the operator has completed the positioning operation of the chassis and the lower pressure plate, further improving the ease of paneling operation.

[0012] Furthermore, the support assembly also includes at least two sets of secondary pressure plates, which are driven by a third drive mechanism to rotate up and down relative to the worktable. In the initial state, the secondary pressure plates avoid the frame and the cardboard; in the working state, the secondary pressure plates rotate toward the frame and the cardboard until the cardboard is pressed firmly against the frame. This results in a stronger connection between the cardboard and the frame in the working state, preventing the cardboard from shifting during the pressing process and improving the stability of the pressing operation.

[0013] Furthermore, the support assembly also includes symmetrically arranged secondary support parts, each with a recessed support groove at its top. These secondary support parts are configured to fit against the side frames on both sides of the frame via the support groove. This results in a stronger connection between the frame and the support assembly, reducing the likelihood of shifting during paneling and rotation operations, and enhancing stability.

[0014] Furthermore, the support groove is an arc-shaped groove with a curved bottom surface. This makes the shape of the support groove fit the frame better, thereby further enhancing the connection strength between the frame and the secondary support, resulting in higher stability.

[0015] The frame auxiliary panel fitting provided in this application connects the riveting holes on the frame and the cardboard together via at least two positioning protrusions. This ensures that when the cardboard is bent, all other riveting holes on the cardboard and the frame are aligned, facilitating subsequent riveting operations. Furthermore, by incorporating a lower pressure plate with an arc consistent with the frame, the lower pressure plate is automatically moved downwards by a first drive mechanism during operation, bending the cardboard to fit the frame. This eliminates the need for manual bending of the cardboard, reducing workload. Thus, by automatically bending the cardboard and aligning it with the riveting holes on the cardboard and frame using the frame auxiliary panel fitting, the operator only needs to align the riveting holes and drive in the rivets to complete the assembly work, making the operation easier and effectively improving work efficiency.

Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0019] Please refer to the attached document. Figure 1-7 This application provides a frame-assisted panel fixture, including a workbench 1 and a support frame 2 disposed above the workbench 1. The workbench 1 is provided with a support assembly configured to support and fix a frame 6 and a cardboard 7. The support assembly includes at least two positioning protrusions 310, which are configured to pass through rivet holes 601 on the frame 6 and the cardboard 7, thereby fixing the frame 6 and the cardboard 7 to the support assembly. The support frame 2 is provided with a clamping assembly, which includes a lower pressure plate 4. The lower pressure plate 4 is configured as a curved panel with an arc consistent with that of the frame 6. The lower pressure plate 4 is movably connected to the support frame 2 through a first driving mechanism. The frame auxiliary panel fixture includes a switchable initial state and a working state. In the initial state, the lower pressure plate 4 is in a higher position, and the user can align the rivet holes 601 on the frame 6 and the cardboard 7 with the positioning protrusions 310 and insert them to fix the frame 6 and the cardboard 7 to the support assembly. In the working state, the first drive mechanism drives the lower pressure plate 4 to move downward until the cardboard 7 is bent and pressed against the frame 6.

[0020] In this embodiment, the frame auxiliary panel fixture connects the rivet holes 601 on the frame 6 and the cardboard 7 in series via at least two positioning protrusions 310. This ensures that when the cardboard 7 is bent, the remaining rivet holes 601 on the cardboard 7 and the frame 6 are aligned, facilitating subsequent riveting operations. Furthermore, by setting a lower pressure plate 4 with the same curvature as the frame 6, in operation, the lower pressure plate 4 is automatically moved downwards by the first drive mechanism, bending the cardboard 7 to fit against the frame 6. This eliminates the need for manual bending of the cardboard 7, reducing workload. Thus, by automatically bending the cardboard 7 and aligning it with the rivet holes 601 on the cardboard 7 and the frame 6 using the frame auxiliary panel fixture, the operator only needs to align the rivet holes and drive in the rivets to complete the assembly work, making the operation easier and effectively improving work efficiency.

[0021] The first drive mechanism includes a first cylinder 210 and a vertical first push-pull rod 211. The lower end of the first push-pull rod 211 is connected to the upper end of the lower pressure plate 4, and the first cylinder 210 drives the first push-pull rod 211 to move up and down, thereby driving the lower pressure plate 4 to move up and down, making the pressing operation of the lower pressure plate 4 more stable and smooth.

[0022] The workbench 1 is also equipped with a control panel 8, which is configured as an integrated control frame auxiliary panel fixture. The operator can use the control panel 8 to switch the status of the frame auxiliary panel fixture or adjust the parameters of various drive mechanisms, etc.

[0023] Please refer to the attached document. Figure 1 In some embodiments of this application, the support component is provided with two symmetrical positioning protrusions 310.

[0024] In this embodiment, by setting two positioning protrusions 310 at the front and back, which are exactly aligned with the two rivet holes 601 on the front and back sides of the frame 6 and the cardboard 7, the structure is simple and the cardboard 7 can be placed stably on the frame 6, which is relatively stable.

[0025] Of course, in other embodiments of this application, the number of positioning protrusions 310 can also be three, four, five, etc.

[0026] Please refer to the attached document. Figure 6-7In some embodiments of this application, the support component includes a second driving mechanism configured to drive the positioning protrusion 310 to move up and down. In the working state, when the cardboard 7 is pressed against the frame 6, the second driving mechanism drives the positioning protrusion 310 to move downwards, causing the positioning protrusion 310 to avoid the rivet holes 601 on the frame 6 and the cardboard 7. This allows workers to also install rivets in the corresponding rivet holes at the positioning protrusion 310, further improving the ease of operation.

[0027] The second drive mechanism includes a second cylinder 311 and a vertical second push-pull rod 312. A positioning protrusion 310 protrudes from the upper end of the second push-pull rod 312, and the diameter of the second push-pull rod 312 is larger than that of the positioning protrusion 310. The second cylinder 311 drives the second push-pull rod 312 to move up and down, thereby driving the positioning protrusion 310 to move up and down. The second push-pull rod 312 can support the bottom end of the frame 6, preventing the frame 6 from sinking further.

[0028] Please refer to the attached document. Figure 2-3 In some embodiments of this application, the support assembly includes a chassis 3, with a positioning protrusion 310 fixed to the top of the chassis 3; the chassis 3 is connected to the worktable 1 via a first rotating mechanism, so that the chassis 3 can rotate horizontally relative to the worktable 1; the lower pressure plate 4 is connected to the first drive mechanism via a second rotating mechanism, so that the lower pressure plate 4 can rotate horizontally relative to the support frame 2.

[0029] In this embodiment, since the frame 6 and cardboard 7 are provided with rivet holes 601 around their perimeter, when the frame 6 and cardboard 7 are in fixed positions, the operator needs to frequently move around the workbench 1 to insert rivets during the riveting operation, which is quite inconvenient. Therefore, by rotatably connecting the chassis 3 to the workbench 1 and the lower pressure plate 4 to the first drive mechanism, when the lower pressure plate 4 presses the cardboard 7 against the frame 6, the operator can rotate the frame 6 and the cardboard 7 as a whole by means of the rotation of the lower pressure plate 4 and the chassis 3. That is, after inserting a rivet into each pair of rivet holes 601, the operator only needs to rotate the frame 6 to perform the riveting operation on the next rivet hole 601, thereby further improving the convenience of the riveting operation.

[0030] The first rotating mechanism includes a rotating shaft 110 located at the top of the workbench 1, and the chassis 3 is rotatably connected to the workbench 1 via the rotating shaft 110. The second rotating mechanism includes a ball bearing 410 located at the top of the lower pressure plate 4, and the lower end of the first push-pull rod 211 is connected to the ball bearing 410, so that the lower pressure plate 4 can rotate relative to the first push-pull rod 211.

[0031] Please refer to the attached document. Figure 4In some embodiments of this application, in the initial state, when the chassis 3 rotates to a preset angle, the first rotating mechanism stops rotating, so that the chassis 3 is fixed in the current position; when the lower pressure plate 4 rotates to a preset angle, the second rotating mechanism stops rotating, so that the lower pressure plate 4 is fixed in the current position; when both the chassis 3 and the lower pressure plate 4 rotate to the preset angle, the curved surface of the lower pressure plate 4 aligns with the frame 6 on the support assembly.

[0032] In this embodiment, since the chassis 3 and the lower pressure plate 4 can rotate independently, the rotation angle of the lower pressure plate 4 may not be consistent with that of the chassis 3 in the initial state, causing the lower pressure plate 4 to fail to align with the frame 6 on the support assembly. Therefore, by setting the first and second rotation mechanisms to stop rotating when they reach a preset angle, the curved surface of the lower pressure plate 4 is aligned with the frame 6 on the support assembly. At this time, the frame auxiliary panel fixture can be switched to the working state to press the cardboard 7, making the positioning operation more convenient.

[0033] Please refer to the attached document. Figure 2-3 In some embodiments of this application, a first sensing mechanism is provided between the chassis 3 and the worktable 1. The first sensing mechanism includes a first sensor 5a disposed on the worktable 1 and a first receiver 5b disposed on the bottom of the chassis 3. A second sensing mechanism is provided between the lower pressure plate 4 and the support frame 2. The second sensing mechanism includes a second sensor 5c disposed on the support frame 2 and a second receiver 5d disposed on the lower pressure plate 4. In the initial state, when the chassis 3 rotates to a preset angle, the first sensor 5a aligns with the first receiver 5b, and the first rotation mechanism stops rotating. When the lower pressure plate 4 rotates to a preset angle, the second sensor 5c aligns with the second receiver 5d, and the second rotation mechanism stops rotating.

[0034] In this embodiment, by setting the first sensing mechanism and the second sensing mechanism to assist in positioning the rotation angle of the chassis 3 and the lower pressure plate 4, the positioning operation is made simpler and more accurate, ensuring that the curved surface of the lower pressure plate 4 can be aligned with the frame 6 on the support component after positioning.

[0035] Preferably, both the first sensor 5a and the second sensor 5c are infrared sensors. The first receiver 5b is a plate-shaped component disposed at the bottom of the chassis 3, and the second receiver 5d is a vertical column-shaped component disposed at the top of the lower pressure plate 4. When the chassis 3 and the lower pressure plate 4 rotate to a preset angle, the infrared light emitted by the first sensor 5a contacts the first receiver 5b and is reflected back. The first sensor 5a outputs an electrical signal and controls the chassis 3 to stop rotating. Similarly, the infrared light emitted by the second sensor 5c contacts the second receiver 5d and is reflected back. The second sensor 5c outputs an electrical signal and controls the lower pressure plate 4 to stop rotating. This high sensitivity and rapid response allow the chassis 3 and the lower pressure plate 4 to stop precisely at the preset angle.

[0036] Please refer to the attached document. Figure 4-5 In some embodiments of this application, in the initial state, when both the chassis 3 and the lower pressure plate 4 rotate to a preset angle, the frame auxiliary paneling fixture automatically switches to the working state, and the first drive mechanism drives the lower pressure plate 4 to move downward. This eliminates the need for manual control of the frame auxiliary paneling fixture to switch states after the operator completes the positioning operation of the chassis 3 and the lower pressure plate 4, further improving the ease of paneling operation.

[0037] Please refer to the attached document. Figure 6-7 In some embodiments of this application, the support assembly further includes at least two sets of secondary pressure plates 320. The secondary pressure plates 320 are driven by a third drive mechanism to rotate up and down relative to the worktable 1. In the initial state, the secondary pressure plates 320 avoid the frame 6 and the cardboard 7. In the working state, the secondary pressure plates 320 rotate toward the frame 6 and the cardboard 7 until the cardboard 7 is pressed tightly against the frame 6.

[0038] In this embodiment, the auxiliary pressure plate 320 assists in pressing the cardboard 7, resulting in a higher connection strength between the cardboard 7 and the frame 6 during operation. Furthermore, during operation, the positioning protrusion 310 is driven down by the first driving mechanism to avoid the rivet hole 601. The auxiliary pressure plate 320 assists in positioning the cardboard 7 and the frame 6, thereby preventing the cardboard 7 from shifting during the board-fitting process, which would cause the cardboard 7 and the frame 6 to fail to align, thus improving the stability of the board-fitting operation.

[0039] Preferably, the support assembly includes two sets of sub-pressure plates 320, one at the front and one at the back, both sets of sub-pressure plates 320 being positioned next to the positioning protrusion 310. This allows the sub-pressure plates 320 to assist in positioning the front and rear ends of the frame 6 and the cardboard 7 during operation, and also prevents the cardboard 7 from shifting after the positioning protrusion 310 is lowered. The third drive mechanism includes a third cylinder 321, which drives the sub-pressure plates 320 to rotate up and down or spiral up and down, making the pressing operation of the sub-pressure plates 320 on the cardboard 7 more stable and smooth.

[0040] Please refer to the attached document. Figure 1 In some embodiments of this application, the support component further includes a secondary support portion 330 arranged symmetrically on the left and right sides. The top end of the secondary support portion 330 is recessed to form a support groove 331. The secondary support portion 330 is configured to fit against the side frames on both sides of the frame 6 through the support groove 331.

[0041] In this embodiment, by setting the secondary support part 330 to support the side frame of the frame 6, the connection strength between the frame 6 and the support component is higher, and it is not easy to deviate during the paneling and rotation operation, resulting in higher stability.

[0042] Please refer to the attached document. Figure 1 In some embodiments of this application, the support groove 331 is an arc-shaped groove with an arc-shaped curved bottom surface.

[0043] In this embodiment, the frame 6 is made of tubular parts. By setting the support groove 311 as an arc groove, the shape of the support groove 311 fits the frame 6 better, thereby further enhancing the connection strength between the frame 6 and the secondary support 330 and making it more stable.
