[0022] The following further elaborates on the present utility model in conjunction with the accompanying drawings.

[0023] Please refer to Figures 1 to 4 For achieving the above object, the present utility model provides the following technical solutions:

[0024] A fixture for processing automotive seat sheet metal pipe fittings includes a bottom cabinet 1. A table top panel 2 is provided at the upper end of the bottom cabinet 1. A fixture base 3 is provided at the upper end of the table top panel 2. A seat frame 4 is installed on the fixture base 3. The seat frame 4 includes a frame body 401 and a first sheet metal pipe fitting 402 and a second sheet metal pipe fitting 403 arranged on both sides of the frame body 401. A reinforcing rib 404 is provided at one end of the first sheet metal pipe fitting 402 and the second sheet metal pipe fitting 403 away from the frame body 401. A first detection component 5 is provided at one end of the first sheet metal pipe fitting 402 close to the reinforcing rib 404. A second detection component 6 is provided at one end of the second sheet metal pipe fitting 403 close to the reinforcing rib 404. A support cross beam 7 is provided between the first detection component 5 and the second detection component 6. A first positioning component 8 is provided on one side of the fixture base 3 close to the first sheet metal pipe fitting 402. A second positioning component 9 is provided on one side of the fixture base 3 close to the second sheet metal pipe fitting 403. The first positioning component 8 and the second positioning component 9 have the same structure and are symmetrically arranged. A clamping component 10 is provided at one end of the fixture base 3 close to the frame body 401. The clamping component 10 abuts against the frame body 401.

[0025] During operation, first place the seat frame 4 to be detected on the fixture base 3; then start the first positioning component 8. Through the first rotary clamping cylinder 802 on the first support base 801, drive the first support arm 803 and the first pressing head 804 to descend until the first pressing head 804 contacts the upper part of the first sheet metal pipe fitting 402 and applies a certain pressure to achieve preliminary positioning; meanwhile, the first support block 11 and the first positioning pin 12 below the first sheet metal pipe fitting 402 cooperate with the positioning holes on the sheet metal pipe fitting to achieve precise positioning; similarly, the second rotary clamping cylinder 902 in the second positioning component 9 drives the second support arm 903 and the second pressing head 904 to position and clamp the second sheet metal pipe fitting 403, and at the same time, the second support block 13 and the second positioning pin 14 ensure the precise positioning of the sheet metal pipe fitting; start the double-axis cylinder 1002 in the clamping component 10, push the movable plate 1003 and the flexible clamping plate 1004 towards the seat frame 4 body until the flexible clamping plate 1004 tightly abuts against the frame body 401 and applies an appropriate clamping force to ensure that the seat frame 4 does not move or deform during the detection process; then, control the first electric telescopic rod 502 in the first detection component 5 to start, drive the first detection pin 503 to move horizontally until the first detection pin 503 is inserted into the corresponding mounting hole on the first sheet metal pipe fitting 402. Through the insertion situation of the first detection pin 503, it can be judged whether the position, size and shape of the mounting hole on the first sheet metal pipe fitting 402 meet the requirements; while the first detection component 5 is detecting, the second electric telescopic rod 602 in the second detection component 6 also starts, driving the second detection pin 603 to detect the mounting hole on the second sheet metal pipe fitting 403, and the method is the same as that of the first sheet metal pipe fitting 402; according to the detection results of the first detection component 5 and the second detection component 6, evaluate whether the processing quality of the seat sheet metal pipe fitting is qualified, including whether the position accuracy, size accuracy and shape of the mounting hole meet the design requirements; after the detection is completed, first release the clamping force of the clamping component 10, then sequentially turn off the driving devices of the positioning component and the detection component, and finally remove the seat frame 4 from the fixture base 3; through the above steps, the fixture for processing the seat sheet metal pipe fitting of the automobile seat can efficiently and accurately complete the detection work of the seat sheet metal pipe fitting, ensuring that the product quality meets the design requirements.

[0026] Please refer to Figure 1 、 Figure 3 As an embodiment of the present invention, the first positioning component 8 includes a first support base 801, and a first rotary clamping cylinder 802 is provided at the upper end of the first support base 801; the top end of the piston rod of the first rotary clamping cylinder 802 is provided with a first support arm 803, and a first pressing head 804 is provided at the top end of the first support arm 803, and the first pressing head 804 is arranged above the first sheet metal pipe fitting 402.

[0027] In the above-described solution, the first positioning component 8 is installed on the fixture base 3 and is close to the side of the first sheet metal pipe fitting 402. At this time, the first support base 801 is firmly fixed on the base. The first rotary pressing cylinder 802 is in an inactive state, and the piston rod is fully retracted. The first support arm 803 and the first pressing head 804 are in the starting position, away from the first sheet metal pipe fitting 402. When it is necessary to position the first sheet metal pipe fitting 402, first start the first rotary pressing cylinder 802. After the first rotary pressing cylinder 802 receives the control signal, it starts to work and drives its piston rod to extend upward. As the piston rod extends, the first support arm 803 rises accordingly. The first support arm 803, as a connecting member, converts the linear motion of the first rotary pressing cylinder 802 into the vertical motion of the first pressing head 804. When the first support arm 803 rises to a certain height, the first pressing head 804 also approaches the first sheet metal pipe fitting 402. At this time, the first pressing head 804 should be directly above the first sheet metal pipe fitting 402 but has not yet contacted it. Continue to drive the first rotary pressing cylinder 802 to further extend the piston rod, thereby pushing the first support arm 803 and the first pressing head 804 to continue rising. When the first pressing head 804 contacts the surface of the first sheet metal pipe fitting 402, the first rotary pressing cylinder 802 continues to apply pressure, and firmly presses the first sheet metal pipe fitting 402 against the fixture base 3 through the first pressing head 804. The magnitude of the pressing force should be adjusted according to the material, size, and detection requirements of the first sheet metal pipe fitting 402 to ensure that the first sheet metal pipe fitting 402 does not move or deform during the detection process. Once the first sheet metal pipe fitting 402 is firmly positioned and pressed, subsequent detection work can be carried out. At this time, other detection tools such as the first detection component 5 can start to work to detect various parameters of the first sheet metal pipe fitting 402.

[0028] Please refer to Figure 3 , as an embodiment of the present utility model, a first support block 11 is provided below the first sheet metal pipe fitting 402. A first positioning pin 12 is provided at the top of the first support block 11, and a positioning hole (not shown in the figure) adapted to the first positioning pin 12 is opened at the lower end of the first sheet metal pipe fitting 402.

[0029] In the above-described solution, the design of the first support block 11 should consider the stability of the support and the adaptability to the sheet metal pipe fitting. When the first sheet metal pipe fitting 402 is placed on the inspection fixture base 3, its lower end needs to be aligned with the first support block 11. At this time, the operator should ensure that the position of the first sheet metal pipe fitting 402 is roughly correct so that the first positioning pin 12 can smoothly enter the positioning hole. As the first sheet metal pipe fitting 402 is further placed or adjusted, the first positioning pin 12 will automatically insert into the positioning hole at the lower end of the first sheet metal pipe fitting 402. This process may require slight adjustment or alignment to ensure that the first positioning pin 12 fully and accurately enters the positioning hole. Once the first positioning pin 12 is fully inserted into the positioning hole, it will play a role in positioning and fixing. The cooperation between the first positioning pin 12 and the positioning hole restricts the movement of the first sheet metal pipe fitting 402 in the horizontal and vertical directions, thereby ensuring the precise positioning of the first sheet metal pipe fitting 402. At the same time, the first support block 11 also provides additional supporting force to prevent the first sheet metal pipe fitting 402 from deforming or moving due to uneven force during the detection process, thereby ensuring the accuracy of the detection result.

[0030] Please refer to Figure 1 , Figure 3 , as an embodiment of the present utility model, the second positioning assembly 9 includes a second support seat 901, wherein a second rotary clamping cylinder 902 is provided at the upper end of the second support seat 901; a second support arm 903 is provided at the top end of the piston rod of the second rotary clamping cylinder 902, wherein a second pressure head 904 is provided at the top end of the second support arm 903, and the second pressure head 904 is arranged above the second sheet metal pipe fitting 403; a second support block 13 is provided below the second sheet metal pipe fitting 403, wherein a second positioning pin 14 is provided at the top end of the second support block 13, and a positioning hole (not shown in the figure) adapted to the second positioning pin 14 is opened at the lower end of the second sheet metal pipe fitting 403.

[0031] In the above-described solution, the second positioning component 9 has the same function and working principle as the first positioning component 8, and the second positioning component 9 and the first positioning component 8 operate synchronously. After the staff places the seat frame 4 on the fixture base 3, the second rotary clamping cylinder 902 is activated. After receiving the control signal, the second rotary clamping cylinder 902 starts to work, driving its piston rod to extend upward. As the piston rod extends, the second support arm 903 also rises, driving the second pressing head 904 to move above the second sheet metal pipe fitting 403. When the second pressing head 904 approaches the second sheet metal pipe fitting 403, the second rotary clamping cylinder 902 is continuously driven to make the second pressing head 904 contact the surface of the second sheet metal pipe fitting 403 and apply a certain pressure. At this time, the second pressing head 904 plays a clamping role, fixing the second sheet metal pipe fitting 403 on the second support block 13. At the same time, the second positioning pin 14 should automatically insert into the positioning hole at the lower end of the second sheet metal pipe fitting 403. The cooperation between the second positioning pin 14 and the positioning hole ensures the precise positioning of the second sheet metal pipe fitting 403 in the horizontal and vertical directions. After the second sheet metal pipe fitting 403 is precisely positioned and fixed, the second detection component 6 can move to the predetermined position to detect various parameters of the second sheet metal pipe fitting 403. During the entire detection process, the second positioning component 9 will maintain the stability of the second sheet metal pipe fitting 403. Even affected by external forces or vibrations, due to the clamping effect of the second pressing head 904 and the fixing effect of the second positioning pin 14, the second sheet metal pipe fitting 403 can maintain its position unchanged, providing stable support and guarantee for the subsequent detection work.

[0032] Please refer to Figure 4 , as an embodiment of the present invention, the clamping component 10 includes a base 1001, wherein the lower end of the base 1001 is fixedly connected to the table top plate 2; a double-axis cylinder 1002 is fixedly installed at the upper end of the base 1001, and the front end of the piston rod of the double-axis cylinder 1002 is connected to a movable plate 1003; a flexible clamping plate 1004 is fixedly installed at the front end of the movable plate 1003, and the flexible clamping plate 1004 abuts against the outer wall of the seat frame 4; linear slide rails 15 are symmetrically installed on both sides of the double-axis cylinder 1002, and sliders 16 adapted to the linear slide rails 15 are installed on both sides of the rear end of the flexible clamping plate 1004.

[0033] In the above-described solution, the flexible splint 1004 is fixedly installed at the front end of the movable plate 1003. Its material and structural design have a certain degree of flexibility and elasticity, so as to adapt to the shape and size changes of the outer wall of the seat frame 4 during the clamping process, and at the same time avoid damaging the seat frame 4; in the unactivated state, there is a certain gap between the flexible splint 1004 and the outer wall of the seat frame 4, so as to place the seat frame 4 into the clamping area; when it is necessary to clamp the seat frame 4, the double-axis cylinder 1002 receives a control signal and starts to work, and the two piston rods extend forward simultaneously, pushing the movable plate 1003 to move forward; during the forward movement of the movable plate 1003, the flexible splint 1004 is driven to approach the outer wall of the seat frame 4 together. Since sliders 16 adapted to the linear slide rails 15 are installed on both sides of the rear end of the flexible splint 1004, the flexible splint 1004 can maintain a smooth and accurate trajectory during the movement; when the flexible splint 1004 contacts the outer wall of the seat frame 4, as the piston rods of the double-axis cylinder 1002 continue to extend, the flexible splint 1004 gradually applies a clamping force to the seat frame 4; due to the flexibility and elasticity of the flexible splint 1004, it can closely fit the outer wall of the seat frame 4, and at the same time ensure that the clamping force is evenly distributed, avoiding deformation or damage of the seat frame 4 caused by excessive local pressure; in the clamped state, the double-axis cylinder 1002 maintains a certain output pressure to maintain the clamping force of the flexible splint 1004 on the seat frame 4. This clamping force should be stable enough to ensure that the seat frame 4 can be maintained in a predetermined position without moving or shaking during the subsequent detection process; when it is necessary to release the seat frame 4, the double-axis cylinder 1002 receives an opposite control signal and starts to work in the reverse direction. As the flexible splint 1004 gradually moves away from the outer wall of the seat frame 4, the clamping force gradually decreases until it is completely released. At this time, the seat frame 4 can be easily taken out from the clamping area; during the release process, the cooperation of the linear slide rails 15 and the sliders 16 ensures the smooth movement and reset of the flexible splint 1004; at the same time, the synchronous movement of the double-axis cylinder 1002 also ensures the synchronous release of the flexible splints 1004 on both sides, avoiding problems such as uneven clamping force or damage caused by non-synchronization.

[0034] Please refer to Figure 3 , as an embodiment of the present utility model, the first detection assembly 5 includes a first detection bracket 501, wherein a first electric telescopic rod 502 is horizontally provided on the outer side of the upper end of the first detection bracket 501; the cylinder body of the first electric telescopic rod 502 is fixedly connected to the first detection bracket 501, and a first detection pin 503 is fixedly connected to the top end of the movable rod of the first electric telescopic rod 502; the first detection pin 503 penetrates through the first detection bracket 501 and extends towards the first sheet metal pipe fitting 402, and the first detection pin 503 corresponds to an installation hole (not shown in the figure) opened on the first sheet metal pipe fitting 402.

[0035] In the above-described solution, before the detection, it is necessary to ensure that the first sheet metal pipe fitting 402 has been placed at the predetermined detection position, and the mounting holes thereon are clearly visible and free of obstacles, in order to ensure that the first detection pin 503 can smoothly enter the mounting hole; the movable rod of the first electric telescopic rod 502 is in the initial position (usually the retracted state), and at this time, the first detection pin 503 does not contact the first sheet metal pipe fitting 402; when the preparation work is completed, the first electric telescopic rod 502 receives a control signal and starts to work, and the movable rod gradually extends under the drive of the first electric telescopic rod 502, and drives the first detection pin 503 to move towards the mounting hole on the first sheet metal pipe fitting 402; as the movable rod extends, the first detection pin 503 gradually approaches and finally penetrates into the mounting hole of the first sheet metal pipe fitting 402; in this process, the diameter and shape of the first detection pin 503 should match the mounting hole to ensure that it can smoothly pass through without damaging the first sheet metal pipe fitting 402; when the first detection pin 503 completely passes through the mounting hole, the control system will receive a signal indicating that the detection has been completed, and at this time, it can be judged whether the position and size of the mounting hole of the first sheet metal pipe fitting 402 meet the requirements; during the detection process, it is necessary to record the time, force or other relevant parameters required for the first detection pin 503 to penetrate the mounting hole, and these data are crucial for evaluating the quality, precision and consistency of the first sheet metal pipe fitting 402; according to the recorded data and the preset standards or specification requirements, the detection result of the mounting hole of the first sheet metal pipe fitting 402 can be judged; if the detection result meets the requirements, the subsequent production or processing process can be continued; if it does not meet the requirements, corresponding measures need to be taken for repair or replacement.

[0036] Please refer to Figure 3 , as an embodiment of the present utility model, the second detection assembly 6 includes a second detection bracket 601, wherein a second electric telescopic rod 602 is horizontally provided on the outer side of the upper end of the second detection bracket 601; the cylinder body of the second electric telescopic rod 602 is fixedly connected to the second detection bracket 601, and the top end of the movable rod of the second electric telescopic rod 602 is fixedly connected with a second detection pin 603; the second detection pin 603 penetrates through the second detection bracket 601 and extends towards the second sheet metal pipe fitting 403, and the second detection pin 603 corresponds to the mounting hole (not shown in the figure) opened on the second sheet metal pipe fitting 403.

[0037] In the above-described solution, the second detection component 6 and the first detection component 5 have the same working principle and operate synchronously. When the second electric telescopic rod 602 receives the start signal, the movable rod gradually extends and drives the second detection pin 603 to move towards the mounting hole on the second sheet metal pipe fitting 403. As the movable rod extends, the second detection pin 603 gradually approaches and finally penetrates into the mounting hole of the second sheet metal pipe fitting 403. During this process, the diameter, shape, and material of the second detection pin 603 should match the mounting hole to ensure that it can pass through smoothly without damaging the second sheet metal pipe fitting 403. When the second detection pin 603 completely passes through the mounting hole, the control system will receive a corresponding signal indicating that the detection is completed. At this time, the control system can record relevant data, such as penetration time, force, etc., for subsequent analysis and judgment.

[0038] Please refer to Figure 1 , as an embodiment of the present utility model, universal locking wheels 17 are respectively installed at the four corner positions of the lower end of the base cabinet 1.

[0039] In the above-described solution, the universal locking wheels 17 are precisely installed at the four corners of the lower end of the base cabinet 1 to ensure the stability and balance of the base cabinet 1 during movement or rest. Among them, the universal locking wheels 17 combine the characteristics of universal wheels and locking mechanisms. The universal wheels allow the base cabinet 1 to move freely on the horizontal plane with flexible directions, facilitating the easy movement of the base cabinet 1 to the designated position when needed. The locking mechanism can prevent the base cabinet 1 from sliding or moving by locking the wheels when it is necessary to fix the base cabinet 1, ensuring its stability during work or use.
