[0032] See also Figure 1-Figure 3 The figure shows a clamping and positioning tool for processing a seat armrest bracket, comprising a body 1, a clamping mechanism 3 and a swinging mechanism 7.

A detection member 10 for detecting the swing amplitude of the armrest bracket 47 is provided on the device box 8, which is used to support the armrest bracket 47 through the positioning frame 9, and link the positioning frame 9 to swing horizontally during the rotation of the flip plate 4, and detect the swing amplitude of the armrest through the detection member 10.

[0033] See also Figure 1-Figure 10The clamping mechanism 3 shown in the figure also includes an electric telescopic rod 11 and a fixed cylinder 12 fixedly installed in the 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 slidably connected to the inner wall of the fixed cylinder 12. The bottom of the flip plate 4 is fixedly connected to a driving plate 14. A driving hole 15 is opened on the driving plate 14. The push-pull rod 13 passes through the driving hole 15. A pushing block 16 for pushing the driving plate 14 is fixedly connected to the push-pull rod 13.

[0034] See also Figure 1-Figure 10 The clamping member 6 shown in the figure includes a first fixed tube 17 coaxially fixedly installed on both sides of the flip frame 5, two sets of second fixed tubes 18 are fixedly connected to the flip plate 4, and clamping rods 19 are slidably connected in the first fixed tube 17 and the second fixed tube 18 respectively. A tension spring 20 fixedly connected to one end of the clamping rod 19 is fixedly connected in the first fixed tube 17 and the second fixed tube 18, and a driving member 21 is provided on the fixed cylinder 12 for slidingly clamping the clamping rod 19 when the push-pull rod 13 slides.

[0035] See also Figure 3-Figure 10 The driving member 21 shown in the figure includes a connecting tube 22 connected to the fixed cylinder 12, one end of the first fixed tube 17 is rotatably connected to one end of the connecting tube 22, the first fixed tube 17 is connected to the connecting tube 22, one end of the second fixed tube 18 is connected to a rotating tube 23, the rotating tube 23 is fixedly connected to the flip plate 4, one end of the rotating tube 23 is rotatably connected to one end of the connecting tube 22, the rotating tube 23 is connected to the connecting tube 22, a fixed shaft 45 is fixedly connected inside the body 1, and the outer wall of the fixed shaft 45 is fixedly connected to a clockwork spring 46 fixedly connected to the flip plate 4.

[0036] In this embodiment, in order to facilitate the tilting and uprighting of the seat back, the armrest bracket 47 generally adopts a group of armrests and a group of support frames for rotational connection. One end of the armrest and the support frame is respectively provided with a group of positioning holes. The positioning holes on the support frame are used to be rotationally connected with the side of the seat cushion through nuts, and the positioning holes on the armrests are used to be rotationally connected 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 groups of second fixed 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 groups of first fixed tubes 17. The placement process is convenient and efficient. An arc-shaped placement groove is provided on the flip plate 4 to facilitate the limiting contact of one end between the armrests.

[0037] The electric telescopic rod 11 is started to push the push-pull rod 13. The push-pull rod 13 does not make the push block 16 conflict with the drive plate 14 in the initial sliding stage. At this time, the hydraulic oil in the fixed cylinder 12 is first pushed into the connecting tube 22, and then transported to the first fixed tube 17 and the rotating tube 23 respectively, and then input into the second fixed tube 18 through the rotating tube 23, pushing the clamping rods 19 on both sides to be inserted into the positioning holes of the armrest bracket 47 synchronously, completing the clamping and fixing while keeping the armrest bracket 47 able to rotate, simulating the state where the armrest bracket 47 is installed on the seat. State, thereafter the push-pull rod 13 continues to be pushed until the push block 16 conflicts with the drive plate 14, pushing the drive plate 14 to make the flip plate 4 rotate around the fixed axis 45, the setting of the clockwork spring 46 ensures that when pushing, the drive plate 14 is always forced to conflict with the push block 16, and then the push-pull rod 13 is continuously pushed and pulled back and forth, but the push block 16 is always kept in a state of conflict 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 is extended, the greater the thrust received by the clamping rod 19, and the clamping is approximately stable.

[0038] When the flip plate 4 rotates, the swing mechanism 7 is linked to make the positioning frame 9 swing back and forth horizontally, and the armrest bracket 47 is shaken left and right. The swing amplitude of the armrest is detected by the detection part 10, and the clamping of the armrest is automatically released after the detection is completed. The device has a high degree of automation and is easy to disassemble and assemble. At the same time, it also improves the detection efficiency of the stability of the armrest bracket 47, and can simulate the swinging condition of the armrest during long-term use. The detection result is convenient to read. Through the rotation connection between the rotating tube 23 and the connecting tube 22 and the rotation connection between the first fixed tube 17 and the connecting tube 22, it is ensured that when the flip plate 4 and the flip frame 5 rotate, the hydraulic oil can always be input into the first fixed tube 17 and the second fixed tube 18, thereby promoting the stable clamping of the clamping rod 19, and after the detection is completed, the push-pull rod 13 is continuously pulled by the electric telescopic rod 11 to reduce the liquid pressure in the connecting tube 22, and the tension spring 20 pulls the clamping rod 19 back, automatically releasing the clamping and fixing of the armrest bracket 47, and the armrest bracket 47 can be directly removed.

[0039] Example 2

[0040] See also Figure 1-Figure 10 Embodiment 2 is described. This embodiment further describes Embodiment 1. The swing mechanism 7 shown 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 to the sliding frame 24 in the vertical direction. 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 to 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. A swing member 28 is provided in the device box 8 for driving the positioning frame 9 to swing when the device box 8 moves.

[0041] See also Figure 5-Figure 12 The swinging member 28 shown in the figure includes a fixed plate 29 fixedly installed at the bottom of the positioning frame 9, a sliding plate 30 is connected to the device box 8 in a horizontal sliding direction, two groups of baffles 31 are fixedly connected to the sliding plate 30, and the two groups of baffles 31 are symmetrically distributed on both sides of the fixed plate 29, and third springs 32 fixedly connected to the baffles 31 are respectively fixedly connected to both sides of the fixed plate 29, and reset springs 33 fixedly connected to the device box 8 are fixedly connected to both sides of the positioning frame 9, and a control member 34 for driving the positioning frame 9 to swing is provided on the sliding plate 30.

[0042] See also Figure 2-Figure 12 The control member 34 shown in the figure includes multiple groups of push columns 41 fixedly installed on the fixed frame 2, and 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 with the outer wall of the push columns 41, and the push columns 41 located on both sides of the device box 8 are alternately distributed at intervals.

[0043] In this embodiment, when the swing plate drives the armrest bracket 47 to rotate, the middle part of the armrest bracket 47 will push the positioning frame 9 to translate and press down, and the device box 8 drives the telescopic tube 25 and the sliding frame 24 to move horizontally in the fixed frame 2, compressing the first spring 26. At the same time, when the device box 8 is lifted or lowered, the second spring 27 will also be compressed, and reset by 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 slide against the side of the push column 41, so that the sliding plate 30 slides back and forth in the device box 8, driving the baffle 31 to move, and 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, and the fixed plate 29 and the positioning frame 9 are subjected to force to produce a tendency to swing left and right, pushing the armrest bracket 47 to swing.

[0044] At this time, if the armrest bracket 47 is relatively stable, the positioning frame 9 can shake less or even hardly swing. When the armrest bracket 47 is loosely connected or the deformation of the material is large, the swing amplitude of the positioning frame 9 will increase. Such reciprocating tests can simulate the stability of the armrest bracket 47 after multiple uses. When resetting, the arc plate 42 no longer conflicts with the push column 41. At this time, the reset springs 33 on both sides have the same thrust on the positioning frame 9, and finally ensure that the positioning frame 9 is reset in the middle position. Among them, the first spring 26, the second spring 27, the third spring 32 and the reset spring 33 all need to be regularly inspected to avoid inaccurate reset caused by unstable elastic force, which affects the detection result.

[0045] Example 3

[0046] See also Figure 2-Figure 12Embodiment 3 is described. Embodiment 1 is further described in this embodiment. The detection member 10 shown in the figure includes two groups of detection tubes 35 fixedly mounted on the device box 8. A detection block 36 is slidably connected in the vertical direction inside the detection tube 35. The bottom end of the detection tube 35 is connected to a sleeve tube 37. 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 for controlling the one-way input of gas into the sleeve tube 37 is fixedly connected to one end of the sleeve tube 37. A one-way exhaust valve 40 for controlling the one-way output of gas from the sleeve tube 37 to the detection tube 35 is fixedly connected to the bottom of 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 a plurality of groups of scale grooves 44 are evenly arranged on the side of the detection tube 35.

[0047] In this embodiment, when the positioning frame 9 swings back and forth left and right, the control rod 38 will slide back and forth in the sleeve tube 37, thereby changing the air pressure in the sleeve tube 37, and drawing the outside air into the sleeve tube 37 through the one-way air inlet valve 39, and then being compressed into the detection tube 35 through the one-way exhaust valve 40, pushing the detection block 36 to move upward. If the stability of the armrest bracket 47 is good, the swing amplitude of the positioning frame 9 is small. After multiple flipping tests, the gas delivery volume of the control rod 38 during the reciprocating push and pull process is small, and the rising distance of the detection block 36 is small. The rise value is read through the scale groove 44. If the rise value is within the set range, it indicates that the test is qualified. If the value exceeds the set value, it means that the swing amplitude of the armrest bracket 47 is too large, the stability is poor, and the test is unqualified.

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