Description
Technical Field
[0001] This utility model relates to the field of seat manufacturing technology, and in particular to a four-way leg rest inspection tool. Background Technology
[0002] In the manufacturing of seats, the leg rest is a crucial component for enhancing seat comfort, making its manufacturing precision and quality paramount. The welded assembly of the leg rest frame and the connecting parts are key components of the leg rest structure; the specifications and positional accuracy of the holes and slots on these components directly affect the installation performance and usability of the leg rest. However, existing inspection procedures for the welded assembly of the leg rest frame and the connecting parts still have the following problems:
[0003] The existing work of inspecting the holes and slots in the leg support mostly relies on traditional manual inspection methods. Inspectors usually use simple measuring tools, such as calipers, to measure the holes and slots on the parts one by one. This inspection method has many drawbacks. On the one hand, manual inspection is inefficient. Because the leg support parts have a complex structure and a large number of holes and slots, inspectors need to spend a lot of time and energy to complete the inspection of a single part, resulting in a slow overall production pace.
[0004] On the other hand, manual testing is easily affected by the subjective factors of the testers. Different testers may have different measurement methods and judgment standards, which may lead to inaccurate and inconsistent test results.
[0005] To address the aforementioned issues, this utility model document proposes a four-way leg support inspection tool. Utility Model Content
[0006] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the low efficiency of traditional inspection which involves manually checking the diameter or spacing of holes and slots one by one with tools such as calipers, and the inaccuracy of the results due to subjective factors. Therefore, a four-way leg support inspection tool is proposed.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] The four-way leg support inspection tool includes:
[0009] A support base, wherein a mounting plate is fixedly installed on the top of the support base, and a fixing bracket is fixedly installed on the top of the mounting plate;
[0010] It also includes a first fixing component and a second fixing component, wherein the first fixing component is disposed on the top of the fixing bracket, and the second fixing component is disposed on the top of the mounting plate and is located on one side of the fixing bracket;
[0011] The first fixing component includes a first fixing frame, and the second fixing component includes a second fixing frame and two third fixing frames, which are used to place and fix the leg support frame welding assembly and leg support connecting parts to be tested;
[0012] It also includes multiple handheld inspection tools, including a first handheld inspection tool and multiple second handheld inspection tools. The ends of the first handheld inspection tool and multiple second handheld inspection tools are fixedly installed with reference pins. The shapes of the multiple reference pins correspond to the holes and slots in the leg support frame welding assembly and the leg support connecting component, so as to inspect the specifications of the corresponding holes and slots in the leg support frame welding assembly and the leg support connecting component.
[0013] In one possible design, the first fixing frame includes a first support column fixedly installed on the top of the fixing bracket, a first mounting bracket fixedly installed on the top of the first support column, and two first positioning pins passing through the top of the first mounting bracket. The first fixing assembly also includes a first support plate and a first abutment plate fixedly installed on the top of the fixing bracket. The first support plate and the first abutment plate are both located on one side of the first fixing frame. A first clamp is provided inside the first support plate for clamping and fixing the components of the leg support frame welding assembly located on the fixing bracket.
[0014] In one possible design, the second fixing frame includes a second support column fixedly mounted on the top of the mounting plate, a second mounting bracket fixedly mounted on the top of the second support column, and second positioning pins penetrating both sides of the second mounting bracket; both third fixing frames include a third support column fixedly mounted on the top of the mounting plate, a third mounting bracket fixedly mounted on the top of both third support columns, and a third positioning pin penetrating the top of both third mounting brackets, with both third positioning pins located at the end of the respective third mounting bracket closest to the first fixing frame; a second support plate and a second abutment plate are fixedly mounted on one side of one of the third support columns, and two third support plates and a third abutment plate are fixedly mounted on one side of the other third support column; a second clamp is provided inside the second support plate, and two third clamps are provided inside both third support plates, which are used to clamp and fix the components of the leg support frame welding assembly located on the mounting plate accordingly.
[0015] In one possible design, the first, second, and third clamps have identical structures, each consisting of a limiting tube, an abutment rod, a rotating handle, and two connecting plates. The limiting tube is fixedly inserted through the corresponding support plate, and the abutment rod slides through the limiting tube. One L-shaped end of the rotating handle is rotatably connected to one end of the abutment rod. Connecting plates are rotatably mounted on both sides of the rotating handle, and the other ends of the two connecting plates are rotatably connected to the outer wall of the limiting tube. This allows the abutment rod to slide within the first support plate when the rotating handle is turned. The other end of the abutment rod cooperates with the adjacent abutment plate to complete the abutment and fixation of the leg support frame welding assembly.
[0016] In one possible design, one end of each of the two second clamps within one of the third support plates is fixedly mounted with a connecting rod, and two pressing rods are rotatably mounted on the side of the third abutment plate away from the third support plate. One end of each of the two connecting rods is rotatably connected to one end of the corresponding pressing rod to achieve lever rotation of the pressing rod, thereby enabling the pressing rod to cooperate with one side of the third abutment plate to further fix the leg support frame welding assembly.
[0017] In one possible design, multiple mounting seats are fixedly mounted on the top of both the mounting plate and the fixing bracket, and detection pins are fixedly mounted on the top of each of the multiple mounting seats. The multiple mounting seats and detection pins are used to provide support and limit the placement of the leg support frame welding assembly.
[0018] In one possible design, two fixing plates are fixedly mounted on the top of the mounting plate. The two fixing plates are used to fix the two leg support connecting components to facilitate the corresponding testing of the two leg support connecting components.
[0019] In one possible design, four casters are fixedly mounted on the bottom of the support base to facilitate the movement of the equipment.
[0020] In this application, when in use, the leg support frame welding assembly is placed at the corresponding position on the top of the mounting plate. At this time, the multiple fixing seats and detection pins set on the top of the mounting plate and the fixing bracket play a supporting and limiting role, so that the leg support frame welding assembly is roughly in the appropriate position.
[0021] Place the leg support frame welding assembly in a suitable position near the first fixing frame, while ensuring that the other parts of the leg support frame welding assembly are in suitable positions near the second and third fixing frames. Then, insert the two first positioning pins that pass through the top of the first mounting frame into the corresponding holes of the leg support frame welding assembly. At the same time, insert the second positioning pins that pass through both sides of the second mounting frame and the third positioning pins that pass through the top of the two third mounting frames into the corresponding holes of the leg support frame welding assembly. At this point, the initial positioning of the leg support frame welding assembly can be completed.
[0022] Next, the first clamp inside the first support plate is rotated. When the handle is rotated, the abutment rod slides in the limiting tube through the two connecting plates. The other end of the abutment rod moves towards the adjacent first abutment plate until the abutment rod abuts against the leg support frame welding assembly, thus completing the clamping and fixing of the leg support frame welding assembly. Then, the corresponding second and third clamps are driven in sequence. Multiple clamps can ensure that the leg support frame welding assembly is clamped and fixed in a comprehensive and stable manner.
[0023] In addition, one end of each of the two second clamps in one of the third support plates is fixedly installed with a connecting rod, which is rotatably connected to one end of a pressing rod that rotates on one side of the third abutment plate. When the corresponding third clamp moves, the pressing rod can be rotated through the lever principle, which in turn allows the pressing rod to fit tightly with one side of the third abutment plate, further completing the fixation of the leg support frame welding assembly.
[0024] Two mounting plates are fixedly installed on the top of the mounting plate. The two leg support connecting parts are fixed to the two mounting plates respectively, which can facilitate simultaneous testing later.
[0025] During testing, a first handheld gauge and multiple second handheld gauges are prepared. Each handheld gauge has a fixed reference pin at its end, and the shape of each reference pin corresponds to a slot in the leg support frame welded assembly or leg support connecting component. The distance between the reference pins on the same handheld gauge also follows a certain standard. The operator inserts the reference pins of the first and multiple second handheld gauges into the corresponding slots in the leg support frame welded assembly or leg support connecting component. If the reference pin can be smoothly inserted into the slot and fits well against the inner wall of the slot, the slot specification meets the requirements. If the reference pin cannot be inserted or there is a large gap between it and the inner wall of the slot after insertion, the slot specification or the distance between two slots does not meet the requirements. This allows for the testing of the specifications of the corresponding slots in the leg support frame welded assembly and leg support connecting component. This gauge enables rapid positioning and placement of the corresponding leg support frame welded assembly, facilitating rapid inspection and effectively improving work efficiency.
[0026] When the four-way leg support fixture needs to be moved, the operator can easily move the equipment to the designated position using the four casters fixed to the bottom of the support base, making it convenient to use.
[0027] Beneficial effects: In this utility model, the four-way leg support inspection tool, through the coordinated action of the first fixing component and the second fixing component, can realize the rapid positioning and placement of the leg support frame welding assembly; the first positioning pin on the first fixing frame, the second positioning pin on the second fixing frame, and the third positioning pin on the third fixing frame can be accurately inserted into the corresponding holes of the leg support frame welding assembly, quickly determine its position, greatly shorten the placement time of the component, and improve the inspection efficiency;
[0028] In this utility model, the four-way leg support inspection tool, through the setting of the first clamp, the second clamp and the third clamp, can comprehensively and stably clamp and fix the leg support frame welding assembly; by rotating the handle to drive the abutment rod to slide in the limiting tube, the abutment and fixation of the component can be realized, which can ensure the stable placement of the leg support component during the inspection process and avoid the impact of component movement on the inspection accuracy.
[0029] In this invention, the four-way leg support inspection tool, with its handheld design, makes the inspection work more efficient and accurate. The ends of the first handheld inspection tool and multiple second handheld inspection tools are all fixedly equipped with reference pins corresponding to the slots in the leg support frame welding assembly and leg support connecting components. Operators only need to insert the reference pins into the corresponding slots to quickly determine whether the slot specifications meet the requirements. This inspection method is not only simple to operate but also allows for simultaneous inspection of multiple slots, greatly improving inspection efficiency while ensuring the accuracy of the inspection results.
[0030] In this invention, the four-way leg support inspection tool, through the coordinated cooperation of two sets of fixing components, accurately inserts each positioning pin into the corresponding hole. With the addition of multiple clamps, it can achieve rapid positioning and placement of the leg support frame welding assembly, shortening placement time and improving inspection efficiency. In addition, the handheld inspection tool is ingeniously designed, with the end reference pin corresponding to the hole groove. The operator only needs to insert the reference pin to quickly determine the hole groove specification. The operation is simple and can simultaneously inspect multiple holes grooves, which improves inspection efficiency and ensures accurate results. Attached Figure Description

[0047] This application can be used in the field of seat manufacturing technology, or in other fields applicable to this application.
[0048] Example 2: Reference Figure 1 , 2 3. Improvement based on Example 1: Four-way leg rest inspection tool, which is applied to the field of seat manufacturing technology;
[0049] In this embodiment, multiple fixing seats 8 are fixedly installed on the top of both the mounting plate 2 and the fixing bracket 4. Detection pins 9 are fixedly installed on the top of each of the multiple fixing seats 8. Both the multiple fixing seats 8 and the detection pins 9 are used to provide support and limit the placement of the leg support frame welding assembly 32, so as to ensure that the leg support frame welding assembly 32 is placed accurately, quickly, and stably.
[0050] In this embodiment, two fixing plates 31 are also fixedly installed on the top of the mounting plate 2. The two fixing plates 31 are used to fix the two leg support connecting parts 33, so as to facilitate the corresponding testing of the two leg support connecting parts 33.
[0051] In this embodiment, four casters 3 are fixedly installed at the bottom of the support base 1 to facilitate the movement of the equipment and improve its flexibility.
[0052] The working principle and usage process of this technical solution are as follows: When in use, the leg support frame welding assembly 32 is placed at the corresponding position on the top of the mounting plate 2. At this time, the multiple fixing seats 8 and detection pins 9 set on the top of the mounting plate 2 and the fixing bracket 4 play a supporting and limiting role, so that the leg support frame welding assembly 32 is roughly in the appropriate position.
[0053] Place the leg support frame welding assembly 32 in a suitable position near the first fixing frame, while ensuring that the other parts of the leg support frame welding assembly 32 are in suitable positions near the second and third fixing frames; then, insert the two first positioning pins 7 that pass through the top of the first mounting frame 6 into the corresponding holes of the leg support frame welding assembly 32, and at the same time, insert the second positioning pins 18 that pass through both sides of the second mounting frame 17 and the third positioning pins 21 that pass through the top of the two third mounting frames 20 into the corresponding holes of the leg support frame welding assembly 32 respectively. At this time, the initial positioning of the leg support frame welding assembly 32 can be completed.
[0054] Then, the first clamp's rotating handle 13 inside the first support plate 10 is turned. When the rotating handle 13 is turned, the abutment rod 12 is driven to slide inside the limiting tube 11 through the two connecting plates 14. The other end of the abutment rod 12 moves towards the adjacent first abutment plate 15 until the abutment rod 12 abuts against the leg support frame welding assembly 32, thus completing the clamping and fixing of the leg support frame welding assembly 32. Then, the corresponding second clamp and third clamp are driven in sequence. Multiple clamps can ensure that the leg support frame welding assembly 32 is clamped and fixed in a comprehensive and stable manner.
[0055] In addition, one end of each of the two second clamps in one of the third support plates 24 is fixedly installed with a connecting rod 26, and the connecting rod 26 is rotatably connected to one end of a pressing rod 27 that rotates on one side of the third abutment plate 25; when the corresponding third clamps move, the pressing rod 27 can be rotated through the lever principle, thereby making the pressing rod 27 tightly cooperate with one side of the third abutment plate 25, which can further complete the fixation of the leg support frame welding assembly 32;
[0056] Two fixing plates 31 are fixedly installed on the top of the mounting plate 2. The two leg support connecting parts 33 are respectively fixed on the two fixing plates 31, which facilitates simultaneous subsequent testing.
[0057] During testing, prepare a first handheld inspection tool 28 and multiple second handheld inspection tools 29. Each handheld inspection tool has a fixed reference pin 30 at its end, and the shape of each reference pin 30 corresponds to the slots in the leg support frame welding assembly 32 and the leg support connecting component 33. The distance between the reference pins 30 on the same handheld inspection tool also follows a certain standard. The operator can insert the reference pins 30 of the first handheld inspection tool 28 and the multiple second handheld inspection tools 29 into the leg support frame welding assembly 32 and the leg support connecting component 33, respectively. If the reference pin 30 can be smoothly inserted into the corresponding slot and fits well against the inner wall of the slot, it indicates that the specifications of the slot meet the requirements; if the reference pin 30 cannot be inserted or there is a large gap between it and the inner wall of the slot after insertion, it indicates that the specifications of the slot or the distance between the two slots do not meet the requirements. This allows for the inspection of the specifications of the corresponding slots in the leg support frame welding assembly 32 and the leg support connecting component 33. This inspection tool can realize the rapid positioning and placement of the corresponding leg support frame welding assembly 32, enabling rapid inspection and effectively improving work efficiency.
[0058] When it is necessary to move the four-way leg support fixture, the operator can easily move the equipment to the designated position using the four casters 3 fixedly installed at the bottom of the support base 1, making it convenient to use.
[0059] The accompanying drawings in this application are for illustrative purposes only.
