Description

Technical Field

[0001] This invention relates to the field of clamping and positioning tooling technology, specifically to a clamping and positioning tooling for processing seat armrest brackets. Background Technology

[0002] Chairs are products that people frequently use in their daily lives. Some office chairs, computer chairs, and gaming chairs, in order to ensure comfort, generally have a reclining backrest. The armrests of these chairs often need to rotate along with the backrest. Over time, this can cause the armrests to loosen. The quality of the armrest supports directly determines the stability and comfort of the chair during use. Therefore, after manufacturing, it is generally necessary to test the strength of the chair's materials and its stability after multiple adjustments and rotations.

[0003] Existing clamping and positioning fixtures for processing seat armrest brackets require manual fixing of the armrests, resulting in low inspection efficiency. They are also inefficient for automated clamping and positioning of the armrests and for detecting their rotation and sway. Manual assembly and disassembly are time-consuming and labor-intensive, significantly reducing the production and inspection efficiency of seat armrests. Therefore, we propose a clamping and positioning fixture for processing seat armrest brackets. Summary of the Invention

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figures 1-3 The figure shows a clamping and positioning fixture for processing a seat armrest bracket, including a body 1, a clamping mechanism 3, and a swinging mechanism 7. A fixed frame 2 is fixedly connected inside the body 1. The clamping mechanism 3 includes a flip plate 4 and a flip frame 5 rotatably connected to the body 1. Both the flip plate 4 and the flip frame 5 are provided with clamping parts 6 for clamping and fixing the armrest bracket 47. The clamping parts 6 are used to clamp and fix the armrest bracket 47 and drive the flip plate 4 to rotate, simulating the state of the seat back flipping. The swinging mechanism 7 includes a device box 8 installed inside the fixed frame 2. A positioning frame 9 is slidably connected in the horizontal direction inside the device box 8. The device box 8 is provided with a detection part 10 for detecting the swing amplitude of the armrest bracket 47. The positioning frame 9 supports the armrest bracket 47 and the positioning frame 9 swings horizontally in conjunction with the rotation of the flip plate 4. The swing amplitude of the armrest is detected by the detection part 10.

[0033] Please see Figures 1-10The clamping mechanism 3 shown in the figure also includes an electric telescopic rod 11 and a fixed cylinder 12 fixedly installed inside the machine body 1. The fixed cylinder 12 is used to store hydraulic oil. The telescopic end of the electric telescopic rod 11 is fixedly connected to a push-pull rod 13 that is slidably connected to the inner wall of the fixed cylinder 12. The bottom of the flip plate 4 is fixedly connected to a drive plate 14. The drive plate 14 has a drive hole 15. The push-pull rod 13 passes through the drive hole 15. A push block 16 for pushing the drive plate 14 is fixedly connected to the push-pull rod 13.

[0034] Please see Figures 1-10 The clamping component 6 shown in the figure includes a first fixing tube 17 coaxially fixedly installed on both sides of the flip frame 5. Two sets of second fixing tubes 18 are fixedly connected to the flip plate 4. Clamping rods 19 are slidably connected in both the first fixing tube 17 and the second fixing tube 18. Tension springs 20 are fixedly connected to one end of the clamping rods 19 in both the first fixing tube 17 and the second fixing tube 18. The fixing cylinder 12 is provided with a driving component 21 for sliding clamping of the clamping rods 19 when the push-pull rod 13 slides.

[0035] Please see Figures 3-10 The driving component 21 shown in the figure includes a connecting pipe 22 that is connected to the fixed cylinder 12. One end of the first fixed pipe 17 is rotatably connected to one end of the connecting pipe 22. The first fixed pipe 17 and the connecting pipe 22 are connected. One end of the second fixed pipe 18 is connected to a rotating pipe 23. The rotating pipe 23 is fixedly connected to the flip plate 4. One end of the rotating pipe 23 is rotatably connected to one end of the connecting pipe 22. The rotating pipe 23 and the connecting pipe 22 are connected. A fixed shaft 45 is fixedly connected inside the body 1. A spring spring 46 that is fixedly connected to the flip plate 4 is fixedly connected to the outer wall of the fixed shaft 45.

[0036] In this implementation scheme, in order to facilitate the reclining and uprighting of the seat back, the armrest bracket 47 generally adopts a method of rotating connection between a set of armrests and a set of support frames. Each end of the armrest and the support frame is provided with a set of positioning holes. The positioning holes on the support frame are used to rotate and connect with the side of the seat cushion through nuts. The positioning holes on the armrests are used to rotate and connect with the side of the backrest through nuts. During testing, the middle part of the armrest bracket 47 is placed on the positioning frame 9, and the positioning hole at one end is placed between the two sets of second fixing tubes 18 on the flip plate 4. The bottom end is inserted into the flip frame 5, so that the positioning hole on the lower side is between the two sets of first fixing tubes 17. The placement process is convenient and efficient. The flip plate 4 is provided with an arc-shaped placement groove to facilitate the limiting and abutment of one end between the armrests.

[0037] Activate the electric telescopic rod 11 and push the push-pull rod 13. In the initial sliding phase, the push-pull rod 13 will not cause the push block 16 to collide with the drive plate 14. At this time, the hydraulic oil in the fixed cylinder 12 will be pushed into the connecting pipe 22 first, and then delivered to the first fixed pipe 17 and the rotating pipe 23 respectively. It will then be input into the second fixed pipe 18 through the rotating pipe 23, pushing the clamping rods 19 on both sides to be inserted into the positioning holes of the armrest bracket 47 simultaneously. This completes the clamping and fixing while allowing the armrest bracket 47 to rotate, simulating the armrest bracket 47 being installed on the seat. Afterwards, the push-pull rod 13 continues to be pushed until the push block 16 contacts the drive plate 14. Pushing the drive plate 14 causes the flip plate 4 to rotate around the fixed shaft 45. The spring spring 46 ensures that the drive plate 14 is always under force and in contact with the push block 16 during the push. Afterwards, the push-pull rod 13 is repeatedly pushed and pulled, but the push block 16 is always kept in contact with the push block 16. At this time, the clamping rod 19 is always pushed into the positioning hole for clamping. The longer the push-pull rod 13 extends, the greater the pushing force on the clamping rod 19, and the more stable the clamping is.

[0038] When the flip plate 4 rotates, the linkage swing mechanism 7 causes the positioning frame 9 to swing horizontally back and forth, causing the handrail bracket 47 to sway left and right. The swing amplitude of the handrail is detected by the detection component 10, and the clamping of the handrail is automatically released after the detection is completed. This device has a high degree of automation, is easy to disassemble and assemble, and also improves the detection efficiency of the stability of the handrail bracket 47. It can simulate the swing of the handrail during long-term use, and the detection results are easy to read. Through the rotational connection between the rotating tube 23 and the connecting tube 22, and the rotational connection between the first fixed tube 17 and the connecting tube 22, it is ensured that hydraulic oil can always be input into the first fixed tube 17 and the second fixed tube 18 when the flip plate 4 and the flip frame 5 rotate, thereby pushing the clamping rod 19 to clamp stably. After the detection is completed, the electric telescopic rod 11 continuously pulls the push-pull rod 13 to reduce the liquid pressure in the connecting tube 22. The tension spring 20 pulls back the clamping rod 19, automatically releasing the clamping fixation of the handrail bracket 47, and the handrail bracket 47 can be directly removed.

[0039] Example 2

[0040] Please see Figures 1-10 Example 2 is described below. This example further illustrates Example 1. The swing mechanism 7 in the figure also includes a sliding frame 24 that is slidably connected to the fixed frame 2 in the horizontal direction. A telescopic tube 25 is slidably connected in the vertical direction inside the sliding frame 24. The upper end of the telescopic tube 25 is fixedly connected to the device box 8. A first spring 26 that is fixedly connected to the bottom surface of the device box 8 is fixedly connected inside the sliding frame 24. A second spring 27 that is fixedly connected to the fixed frame 2 is fixedly connected to the side of the sliding frame 24. The device box 8 is provided with a swinging member 28 for swinging the positioning frame 9 when the device box 8 moves.

[0041] Please see Figures 5-12 The swinging component 28 shown in the figure includes a fixed plate 29 fixedly installed at the bottom of the positioning frame 9, a sliding plate 30 slidably connected in the horizontal direction inside the device box 8, two sets of baffles 31 fixedly connected on the sliding plate 30, the two sets of baffles 31 being symmetrically distributed on both sides of the fixed plate 29, a third spring 32 fixedly connected to the baffle 31 on both sides of the fixed plate 29, a reset spring 33 fixedly connected to the device box 8 on both sides of the positioning frame 9, and a control component 34 for driving the positioning frame 9 to swing on the sliding plate 30.

[0042] Please see Figures 2-12 The control component 34 shown in the figure includes multiple sets of push columns 41 fixedly installed on the fixed frame 2. Both ends of the sliding plate 30 are fixedly connected with arc plates 42. The arc surface of the arc plate 42 can slide and fit against the outer wall of the push column 41. The push columns 41 located on both sides of the device box 8 are distributed alternately at intervals.

[0043] In this embodiment, when the swing plate drives the handrail bracket 47 to rotate, the middle part of the handrail bracket 47 will push the positioning frame 9 to move horizontally and press down. The device box 8 drives the telescopic tube 25 and the sliding frame 24 to move horizontally within the fixed frame 2, compressing the first spring 26. At the same time, when the device box 8 rises and falls, it will also compress the second spring 27 and reset through the rebound of the first spring 26 and the second spring 27. When the device box 8 moves, the arc plates 42 on both sides will alternately abut and slide against the side of the push column 41, so that the sliding plate 30 will slide back and forth within the device box 8, driving the baffle 31 to move. The baffle 31 pushes the fixed plate 29 through the third spring 32, so that the third springs 32 on both sides are alternately compressed. The fixed plate 29 and the positioning frame 9 are subjected to force and tend to swing left and right, pushing the handrail bracket 47 to swing.

[0044] If the handrail bracket 47 is relatively stable, the positioning frame 9 will wobble slightly, or even hardly at all. When the handrail bracket 47 is loosely connected or the material has a large deformation, the positioning frame 9 will wobble more. Repeating this test multiple times can simulate and detect the stability of the handrail bracket 47 after multiple uses. During reset, the arc plate 42 no longer contacts the push column 41. At this time, the reset springs 33 on both sides exert the same force on the positioning frame 9, ultimately ensuring that the positioning frame 9 is in the middle position for reset. The first spring 26, the second spring 27, the third spring 32, and the reset spring 33 all need to be inspected regularly to avoid unstable spring force causing inaccurate reset and affecting the test results.

[0045] Example 3

[0046] Please see Figures 2-12Example 3 further illustrates Example 1. The detection component 10 shown in the figure includes two sets of detection tubes 35 fixedly installed on the device box 8. A detection block 36 is slidably connected in the vertical direction inside the detection tube 35. A sleeve tube 37 is connected to the bottom end of the detection tube 35. Control rods 38 are fixedly connected to both sides of the positioning frame 9. The control rods 38 are slidably connected to the inner wall of the sleeve tube 37 in the horizontal direction. A one-way air inlet valve 39 is fixedly connected to one end of the sleeve tube 37 to control the one-way input of gas into the sleeve tube 37. A one-way exhaust valve 40 is fixedly connected to the bottom of the detection tube 35 to control the one-way output of gas from the sleeve tube 37 into the detection tube 35. A control valve 43 for exhaust is provided on the side of the bottom end of the detection tube 35. The detection tube 35 is made of transparent glass material, and multiple sets of scale grooves 44 are evenly opened on the side of the detection tube 35.

[0047] In this embodiment, when the positioning frame 9 swings back and forth, the control rod 38 slides back and forth within the sleeve 37, causing a change in the air pressure within the sleeve 37. This draws external air into the sleeve 37 through the one-way inlet valve 39, where it is then compressed and enters the detection tube 35 through the one-way exhaust valve 40, pushing the detection block 36 upward. If the stability of the handrail bracket 47 is good, the swing amplitude of the positioning frame 9 is small. After multiple flipping tests, the amount of gas delivered by the control rod 38 during the back-and-forth pushing and pulling process is small, and the rising distance of the detection block 36 is small. The rising value is read through the scale groove 44. If the rising value is within the set range, the test is qualified. If the value exceeds the set value, it indicates that the swing amplitude of the handrail bracket 47 is too large and the stability is poor, and the test is unqualified.

[0048] It is worth noting that the one-way air intake valve 39 and one-way air exhaust valve 40 here have a simple structure, similar to the gas delivery element in an air pump, which ensures that external gas can be continuously pushed into the detection tube 35 when the control lever 38 is pulled back and forth.

[0049] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
