Description

Technical Field

[0001] This utility model relates to the field of seat belt adjustment buckle processing technology, and in particular to a clamping tool for processing seat belt adjustment buckles. Background Technology

[0002] The seatbelt adjuster buckle is a crucial component of the seatbelt system, its development stemming from the dual pursuit of safety and comfort. In the automotive industry, seatbelts were first used on horse-drawn carriages in 1885 to prevent passengers from falling. As the automotive industry developed, seatbelt fixing mechanisms improved, but traditional seatbelt buckles generally only allowed for small forward and backward adjustments, making it difficult to meet the needs of drivers and passengers of different heights. Furthermore, the vibrations of the seatbelt during vehicle operation could cause it to tighten excessively, creating a feeling of constriction and leading some people to avoid wearing seatbelts. To address these issues, the seatbelt adjuster buckle was developed. It allows drivers and passengers to adjust the height and tightness of the seatbelt according to their needs, ensuring both safety and improved comfort, making it an indispensable component for safety. During the production and processing of seatbelt adjuster buckles, clamping fixtures are often used to hold the buckle in place.

[0003] A typical, simple clamping fixture for machining seatbelt adjustment buckles includes a clamping body, connecting components, a positioning structure, and a drive unit. In use, the drive unit is first activated, and its power is transmitted to the clamping body via the connecting components. Initially, the drive unit controls the symmetrical mechanical jaws to be in an open state, facilitating workpiece placement. After the workpiece is placed, positioning structures such as stops and grooves restrict its displacement, ensuring alignment between the center and the clamping point. Subsequently, the jaws close to grip, completing the machining process. The drive unit then reverses its action, causing the jaws to open via the connecting components, releasing the positioning constraints, and allowing the workpiece to be removed, completing one cycle.

[0004] However, this type of clamping fixture for processing seat belt adjustment buckles requires precise placement of the workpiece before and after clamping it, corresponding to the next process. The inability to adjust the height and width leads to docking problems and long operation time. Furthermore, the fixture is designed with fixed dimensions and cannot adapt to adjustment buckles of different sizes and shapes, thus limiting the types of workpieces it can clamp. Therefore, a clamping fixture for processing seat belt adjustment buckles is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a clamping tool for processing seat belt adjustment buckles, which aims to improve the problems of docking and long operation time caused by the non-adjustable height and width in the existing technology, and the inability to adapt to adjustment buckles of different sizes and shapes due to the fixed size design.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping fixture for processing seat belt adjusting buckles, comprising an operating table, a lower slide rail fixedly mounted on the upper side of the operating table, limit plates provided on both sides of the lower slide rail, a cylinder fixedly mounted on the inner side of the limit plate, a fixed plate fixedly connected to the telescopic end of the cylinder, an upper slide rail fixedly mounted on the upper side of the fixed plate, a T-shaped slide rail fixedly mounted on the front side of the fixed plate, a slide groove provided inside the T-shaped slide rail, a T-shaped slider slidably connected inside the T-shaped slide rail, a limit rod fixedly connected to the outer side of the T-shaped slider, a limit block threadedly connected to the outer side of the limit rod, a mounting base fixedly connected to the front side of the T-shaped slider, a limit mechanism provided on the right side of the mounting base, a mechanical gripper provided on the front side of the mounting base, an insert block fixedly mounted on the rear side of the mechanical gripper, and insertion holes provided inside both the insert block and the mounting base.

[0007] Furthermore, the limiting mechanism includes a housing, which is fixedly connected to the right side of the mounting base. A sliding hole is provided inside the housing, and a rotating rod is rotatably connected inside the housing. A gear is fixedly connected to the outer side of the rotating rod. A rack is provided on the upper side of the gear, and an insert is fixedly connected to the left end of the rack. A limiting toothed plate is provided on the lower side of the gear, and a pull rod is fixedly connected to the lower side of the limiting toothed plate. A spring is provided on the outer side of the pull rod, and the upper side of the spring is fixedly connected to the lower side of the limiting toothed plate. The lower side of the spring is fixedly connected to the inner bottom of the housing.

[0008] Furthermore, the fixing plate is slidably connected inside the lower slide rail and the upper slide rail.

[0009] Furthermore, the limiting rod is slidably connected inside the slide groove.

[0010] Furthermore, both the rack and the limiting toothed plate are meshed with the gear.

[0011] Furthermore, a scale is fixedly connected to the rear side of the upper slide rail.

[0012] Furthermore, the insert is slidably connected inside the socket.

[0013] Furthermore, a controller is fixedly installed on the right side of the operating table, and the controller is electrically connected to both the cylinder and the mechanical gripper.

[0014] This utility model has the following beneficial effects:

[0015] 1.

The distance between the fixed plates is adjusted by using a cylinder to adjust the width, and the distance between the mounting bases is adjusted by using sliders and sliding rods to adjust the height, thereby shortening the workpiece transfer and docking time and improving work efficiency.

[0016] 2. In this utility model, by setting up a plug, a hole, a limiting mechanism and a mounting base, the pull rod in the limiting mechanism is pulled open, and then the rotating rod is rotated to make the plug be pulled out from the mounting base. It can be disassembled and replaced, which solves the original limitation problem, so that the tooling can adapt to the clamping of adjusting buckles of different sizes and shapes.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 3 One embodiment of this utility model includes an operating table 1. A lower slide rail 3 is fixedly installed on the upper side of the operating table 1. A limit plate 4 is provided inside the lower slide rail 3. A cylinder 5 is fixedly installed inside the limit plate 4. A fixed plate 8 is fixedly connected to the telescopic end of the cylinder 5. An upper slide rail 6 is fixedly installed on the upper side of the fixed plate 8. A scale 7 is fixedly connected to the rear side of the upper slide rail 6. The fixed plate 8 is slidably connected inside the lower slide rail 3 and the upper slide rail 6. A T-shaped slide rail 11 is fixedly installed on the front side of the fixed plate 8. A slide groove 15 is opened inside the T-shaped slide rail 11. A T-shaped... The slider 10 has a limit rod 12 fixedly connected to its outer side. The limit rod 12 is slidably connected inside the slide groove 15. The limit rod 12 is threadedly connected to a limit block 14. The front side of the T-shaped slider 10 is fixedly connected to a mounting base 9. The right side of the mounting base 9 is fixedly connected to a limit mechanism 13. The front side of the mounting base 9 is provided with a mechanical gripper 18. The rear side of the mechanical gripper 18 is fixedly installed with an insert block 17. Both the insert block 17 and the mounting base 9 have insertion holes 16 inside. The right side of the operating table 1 is fixedly installed with a controller 2. The controller 2 is electrically connected to the cylinder 5 and the mechanical gripper 18.

[0025] Specifically, when using this device, the operator adjusts the width and height according to the requirements of the next process. First, the controller 2 controls the switch of the cylinder 5. The telescopic end of the cylinder 5 extends and retracts horizontally, causing the fixed plate 8 to slide synchronously along the inner side of the upper slide rail 6 and the lower slide rail 3. During the sliding process, the fixed plate 8 is limited by the limiting plate 4 to prevent overtravel. The operator reads the value through the scale 7 on the back of the upper slide rail 6 to confirm the distance between the two fixed plates 8 until the width of the next process is achieved. For the corresponding height adjustment, the operator manually pushes the mounting base 9, causing the T-shaped slider 10 to slide along the inside of the T-shaped slide rail 11. During the sliding process, the limiting rod 12 on the outside of the T-shaped slider 10 slides along the T-shaped slide rail 11. The slide groove 15 inside the rail 11 slides synchronously. The height position of the mounting seat 9 is read by the scale 7 on the outer side of the T-shaped slide rail 11 until it reaches the height suitable for the next process. Tighten the limiting block 14 on the outer side of the limiting rod 12 so that its inner side presses against the outer wall of the T-shaped slide rail 11, fixing the position of the T-shaped slider 10 inside the T-shaped slide rail 11, thereby fixing the height of the mounting seat 9 and the mechanical gripper 18. After the width and height are adjusted, the operating controller 2 controls the mechanical gripper 18 to perform the opening and closing action. Its inner side contacts and clamps the adjusting buckle, completing the clamping work of the adjusting buckle. Adjusting the width and height corresponds to the operation of the next process, which shortens the workpiece transfer and docking time and improves work efficiency.

[0026] Reference Figure 1 and Figure 4The limiting mechanism 13 includes a box body 137, which is fixedly connected to the right side of the mounting base 9. Sliding holes 139 are provided on both sides of the box body 137. A rotating rod 136 is rotatably connected inside the box body 137. A gear 133 is fixedly connected to the outside of the rotating rod 136. A rack 132 is provided on the upper side of the gear 133. An insert 131 is fixedly connected to the left end of the rack 132. The insert 131 is slidably connected inside the insertion hole 16. A limiting tooth plate 138 is provided on the lower side of the gear 133. The rack 132 and the limiting tooth plate 138 are both meshed with the gear 133. A pull rod 135 is fixedly connected to the lower side of the limiting tooth plate 138. A spring 134 is provided on the outside of the pull rod 135. The upper side of the spring 134 is fixedly connected to the lower side of the limiting tooth plate 138. The lower side of the spring 134 is fixedly connected to the inner bottom of the box body 137.

[0027] Specifically, when the size and shape of the adjusting buckle do not match the current mechanical gripper 18, the pull rod 135 is manually pulled outward. The pull rod 135 drives the limiting tooth plate 138 to move downward against the preload of the spring 134, causing the limiting tooth plate 138 to disengage from the gear 133. Then, the rotating rod 136 is rotated clockwise. The rotating rod 136 drives the gear 133 inside the box 137 to rotate synchronously. The gear 133 drives the upper rack 132 to slide to the left along the sliding holes 139 on both sides of the box 137 through meshing transmission. The insert 131 at the left end of the rack 132 moves synchronously with the rack 132 and is completely pulled out from the insertion hole 16 of the mounting base 9 and the insert block 17. Next, slide the current mechanical gripper 18 out horizontally along the groove of the mounting base 9, select the appropriate mechanical gripper 18 module, align the insert 17 on its rear side with the groove of the mounting base 9 and insert it, ensuring that the insert 17 is fully seated; then rotate the rotating rod 136 counterclockwise, the gear 133 rotates in the opposite direction and drives the rack 132 to slide to the right, the insert 131 is inserted into the mounting base 9 and the insertion hole 16 of the insert 17 along with the rack 132; finally, release the pull rod 135, the spring 134 releases its elastic potential energy to reset, pushes the limiting tooth plate 138 to move upward, re-engages with the gear 133, and restricts the rotation of the gear 133 through tooth meshing, thus completing the replacement and locking of the mechanical gripper 18.

[0028] Working principle: When using this fixture, the operator adjusts the width and height according to the next process. First, the operator operates the controller 2 to control the switch of the cylinder 5. The telescopic end of the cylinder 5 drives the fixed plate 8 to slide along the upper slide rail 6 and the lower slide rail 3 to adjust the distance between the fixed plate 8. When adjusting the height, the operator removes the limit block 14, slides the mounting base 9 on the T-shaped slide rail 11, adjusts the distance between the two mechanical grippers 18, and then turns on the controller 2 to start driving the mechanical grippers 18 to perform the gripping work.

[0029] When the size and shape of the adjusting buckle do not match, the spring 134 can be compressed by pulling the lever 135, causing the limiting tooth plate 138 to move down and release the limit on the gear 133. Then, the gear 133 can be rotated by rotating the rotating rod 136. The gear 133 drives the rack 132 and the insert 131 to be pulled out from the insertion hole 16 of the insert block 17. The insert block 17 can be taken out from the mounting base 9, and then a mechanical gripper 18 that is suitable for the current workpiece size and shape can be selected and reinstalled.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
