Description

Technical Field

[0001] This utility model relates to the field of steel reed fixing technology, specifically a steel reed fixing fixture. Background Technology

[0002] As an important pillar industry of the national economy, the textile industry's production efficiency and product quality directly depend on the stable operation of textile machinery. The reed is a key component in the weaving process that controls the density of warp yarns and guides the weft yarns. After long-term use, it is prone to wear, deformation, or breakage of the reed teeth, which affects the quality of the fabric. Therefore, regular inspection and maintenance are important links to ensure the continuity of textile production. During the inspection and maintenance of the reed, it is necessary to use special fixtures to fix it stably to ensure the accuracy of operations such as inspection, polishing, and repair.

[0003] In existing technologies, the fixing methods for reed maintenance mostly adopt bolt-plate or simple clamp structures. The working process is roughly as follows: place the reed on a flat workbench, manually tighten the bolts distributed on both sides of the reed to make the pressure plate in close contact with the surface of the reed, and use friction to achieve fixation; or adjust the opening angle of the clamp to make the claws hold the edge of the reed for positioning. After the maintenance work is completed, the reed is loosened by reversing the operation. However, the existing fixing methods have some problems: First, it is difficult to control the fixing force accurately. If the bolts are too tight, the reed may be deformed or its surface may be damaged. If they are too loose, it may slip during maintenance. Second, the adaptability is poor. For reeds of different thicknesses, the corresponding pressure plate or clamp needs to be replaced. Frequent replacement leads to low maintenance efficiency. Therefore, we propose a reed fixing fixture. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a steel reed fixing fixture that flexibly fixes the steel reed with a rubber seat to avoid damage and is adaptable to steel reeds of different thicknesses without the need for frequent replacement of parts, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel reed fixing fixture, including a base and a fixing component;

[0006] Fixing component: It includes a sliding groove, an extrusion plate, an extrusion protrusion, a rubber seat, and a reed placement groove. The sliding groove is opened on the upper side of the base. The extrusion plates are slidably connected to the inside of the sliding groove. The inner sides of the two extrusion plates are provided with extrusion protrusions. The rubber seat is disposed between the two extrusion plates and cooperates with the extrusion protrusions. The reed placement groove is opened in the middle of the rubber seat. The rubber seat flexibly fixes the reed to avoid damage and is suitable for reeds of different thicknesses, eliminating the need for frequent component replacement.

[0007] Furthermore, the fixing component also includes sliding holes and sliding columns. The base has symmetrically distributed sliding holes in the middle, and sliding columns are slidably connected inside each sliding hole. The upper side of each sliding column is fixedly connected to the lower side of the rubber seat to provide sliding guidance.

[0008] Furthermore, the fixing assembly also includes a mounting plate and a spring. The mounting plate is disposed at the lower end of the front sliding column, and a spring is provided between the upper side of the mounting plate and the top wall of the base. The spring is sleeved on the outer arc surface of the front sliding column for resetting.

[0009] Furthermore, a limiting rod is rotatably connected to the lower side of the mounting plate, and symmetrically distributed limiting posts are provided between the left and right inner walls of the base. The limiting rod is located on the upper side of the middle of the two limiting posts and works in conjunction with the limiting posts, mainly to limit the position of the rubber seat.

[0010] Furthermore, a lead screw is rotatably connected between the left and right inner walls of the chute, and the lower end of the extrusion plate is threadedly connected to the lead screw adjacent to the lower side to adjust the position of the extrusion plate.

[0011] Furthermore, the left and right sides of the base are rotatably connected to rotating shafts, and the inner ends of the rotating shafts are fixedly connected to the center of the outer end face of the horizontally adjacent lead screw, which facilitates the rotation of the lead screw.

[0012] Furthermore, the base is provided with limiting cylinders on both the left and right sides, and the rotating shafts are all located inside the horizontally adjacent limiting cylinders. The outer arc front of the limiting cylinder is threaded with a tightening screw, and the rear end of the tightening screw is fitted with the adjacent rotating shaft on the rear side to lock the rotation of the lead screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This steel reed fixing fixture has the following advantages:

[0014] The extrusion plate and extrusion protrusions form a preset limiting space, which, combined with the elastic deformation of the rubber seat, achieves passive fixation of the reed. This method can flexibly adapt to reeds of different thicknesses, and the rubber material avoids damage to the reed from hard extrusion. The synergistic action of the sliding column and spring provides the rubber seat with a continuous restoring force to fit the extrusion protrusion. Combined with the locking structure of the limiting rod and limiting post, the fixing process is ensured to be stable and reliable. The combination design of the screw, rotating shaft and tightening screw not only facilitates quick adjustment of the extrusion plate position, but also locks the adjusted state. With convenient loading and unloading operations, the efficiency and safety of reed fixing are greatly improved, effectively solving the problems of poor adaptability, easy damage to workpieces and cumbersome operation of traditional fixing methods.

[0019] 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.

[0020] Please see Figure 1-3 This embodiment provides a technical solution: a steel reed fixing fixture, including a base 1 and a fixing component 2;

[0021] Fixed component 2 includes a slide groove 21, an extrusion plate 22, an extrusion protrusion 23, a rubber seat 24, and a reed placement groove 25. The slide groove 21 is located on the upper side of the base 1. The extrusion plates 22 are slidably connected to the interior of the slide groove 21. A lead screw 5 is rotatably connected between the left and right inner walls of the slide groove 21. The lower end of each extrusion plate 22 is threadedly connected to the adjacent lead screw 5 on its lower side (a corrugated tube is provided between the left and right inner walls of the slide groove 21 and the adjacent lower side of the extrusion plate 22, and the lead screw 5 is located inside the corrugated tube to ensure lubrication and sealing). A rotating shaft 6 is rotatably connected to the left and right sides of the base 1. The inner end of each rotating shaft 6 is fixedly connected to the center of the outer end face of the adjacent lead screw 5 laterally. A limiting cylinder 7 is provided on the left and right sides of the base 1, and the rotating shaft 6 is located at the center of the outer end face of the adjacent lead screw 5 laterally. Inside the adjacent limiting cylinder 7, the outer arc face of the limiting cylinder 7 is threaded with a tightening screw 8. The rear end of the tightening screw 8 is installed in conjunction with the adjacent rotating shaft 6 on the rear side. The inner sides of the two extrusion plates 22 are provided with extrusion protrusions 23. The rubber seat 24 is set between the two extrusion plates 22 and is used in conjunction with the extrusion protrusions 23. The middle of the rubber seat 24 is provided with a reed placement groove 25. The fixing component 2 also includes sliding holes 26 and sliding columns 27. The middle of the base 1 is provided with symmetrically distributed sliding holes 26. The sliding columns 27 are slidably connected inside the sliding holes 26. The upper side of the sliding columns 27 is fixedly connected to the lower side of the rubber seat 24. The fixing component 2 also includes a mounting plate 28 and a spring 29. The mounting plate 28 is set at the lower end of the front sliding column 27. A spring 29 is provided between the upper side of mounting plate 28 and the top wall of base 1. The spring 29 is sleeved on the outer arc surface of the sliding column 27 on the front side. The lower side of mounting plate 28 is rotatably connected to a limit rod 3. The left and right inner walls of base 1 are provided with symmetrically distributed limit posts 4. The limit rod 3 is located on the upper side of the middle of the two limit posts 4 and works in conjunction with the limit posts 4. By rotating the rotating shaft 6, the screw 5 is rotated, so that the extrusion plate 22 slides along the slide groove 21 to the preset position (adjusted according to the thickness of the reed). The front side of base 1 is also provided with scale lines. The worker judges the moving distance of the two extrusion plates 22 by observing the position of the extrusion plate 22 corresponding to the scale lines. At this time, a fixed-distance limiting space is formed between the extrusion protrusions 23 on the inner side of the two extrusion plates 22 (the position of the extrusion plate 22 is adjusted during the adjustment). The worker needs to turn the knobs of the two rotating shafts 6 to make the rotating shafts 6 drive the two lead screws 5 to rotate. Under the threaded engagement of the lead screws 5 and the extrusion plate 22 and the rotation restriction engagement of the slide groove 21 on the extrusion plate 22, the extrusion plate 22 slides inside the corresponding slide groove 21. After adjustment, tighten the top screw 8 on the outer arc surface of the limiting cylinder 7 so that its rear end is pressed against the rotating shaft 6 to prevent the rotating shaft 6 from rotating easily. After the reed is placed into the reed placement groove 25 of the rubber seat 24, the worker presses down on the rubber seat 24. As the rubber seat 24 moves down, its side walls gradually enter the limiting space between the extrusion protrusions 23. The extrusion protrusions 23 form a passive block on the side walls of the rubber seat 24. Since the rubber seat 24 is made of elastic material, it undergoes lateral deformation under the limiting action of the extrusion protrusions 23.The internal reed placement groove 25 contracts accordingly, and finally tightly wraps the reed with the elastic force generated by the deformation, thus achieving fixation. When the rubber seat 24 moves down, the mounting plate 28 at the lower end of the front sliding column 27 compresses the spring 29. The elastic potential energy of the spring 29 provides an upward reset tendency for the rubber seat 24, so that the rubber seat 24 always keeps in contact with the extrusion protrusion 23, ensuring the continuity of passive limiting. When the limiting rod 3 moves down to the lower side of the limiting post 4, the worker rotates the limiting rod 3, which can be placed horizontally between the two limiting posts 4. At this time, the limiting post 4 forms an upward supporting force on the limiting rod 3, restricting the sliding column 27 and the rubber seat 24 from resetting upward under the elastic force of the spring 29, thereby locking the rubber seat. The downward movement of position 24 ensures that the rubber seat 24 maintains stable deformation under the passive limitation of the extrusion protrusion 23, thereby ensuring the fixing effect of the reed placement groove 25 on the reed. Rotating the limiting rod 3 on the lower side of the mounting plate 28 disengages it from between the two limiting posts 4, releasing the longitudinal limitation on the sliding column 27. After the limiting rod 3 is unlocked, the spring 29 between the mounting plate 28 at the lower end of the front sliding column 27 and the top wall of the base 1 releases its elastic potential energy, pushing the sliding column 27 upwards, thereby causing the rubber seat 24 to move upwards along the sliding hole 26, disengaging from the passive limitation of the extrusion protrusion 23. The reed can then be directly removed from the reed placement groove 25. This convenient reed fixing method can also accommodate reeds of different thicknesses.

[0022] The working principle of the steel reed fixing fixture provided by this utility model is as follows: By rotating the rotating shaft 6, the lead screw 5 is driven to rotate, causing the extrusion plate 22 to slide along the slide groove 21 to a preset position (adjusted according to the thickness of the steel reed; the front side of the base 1 is also provided with scale lines, and the worker judges the moving distance of the two extrusion plates 22 by observing the position of the extrusion plate 22 corresponding to the scale lines). At this time, a fixed-distance limiting space is formed between the extrusion protrusions 23 on the inner side of the two extrusion plates 22 (when adjusting the position of the extrusion plate 22, the worker needs to rotate the knobs of the two rotating shafts 6, so that the rotating shafts 6 drive the two lead screws 5 to rotate, and the threaded engagement between the lead screw 5 and the extrusion plate 22 and the slide groove 21 on the extrusion plate 22... Under the rotational constraint, the extrusion plate 22 slides inside the corresponding groove 21. After adjustment, tighten the top screw 8 on the outer arc surface of the limiting cylinder 7 so that its rear end is pressed against the rotating shaft 6 (keeping the rotating shaft 6 from rotating). When the reed is placed into the reed placement groove 25 of the rubber seat 24, the worker presses down on the rubber seat 24. As the rubber seat 24 moves down, its side walls gradually enter the limiting space between the extrusion protrusions 23. The extrusion protrusions 23 passively block the side walls of the rubber seat 24. Since the rubber seat 24 is made of elastic material, it undergoes lateral deformation under the limiting action of the extrusion protrusions 23. The reed placement groove 25 inside it contracts accordingly, and finally, the rebound force generated by the deformation is used to achieve the desired effect. The steel reed is tightly wrapped to achieve fixation. When the rubber seat 24 moves down, the mounting plate 28 at the lower end of the front sliding column 27 compresses the spring 29. The elastic potential energy of the spring 29 provides an upward reset tendency for the rubber seat 24, ensuring that the rubber seat 24 always keeps in contact with the extrusion protrusion 23, thus ensuring the continuity of passive limiting. When the limiting rod 3 moves down to the lower side of the two limiting posts 4 (moving down between the two limiting posts 4 when parallel), the worker can rotate the limiting rod 3 to make it horizontally positioned between the two limiting posts 4 (the limiting rod 3 and the two limiting posts 4 form an angle and are no longer parallel). At this time, the bottom surface of the limiting post 4 forms an upward supporting force on the limiting rod 3, limiting the sliding column 27 and the rubber seat 24 to spring. Under the action of the elastic force, the rubber seat 24 is reset upward, thereby locking the downward position of the rubber seat 24 and ensuring that the rubber seat 24 maintains stable deformation under the passive limit of the extrusion protrusion 23. This ensures the fixing effect of the reed placement groove 25 on the reed. The limiting rod 3 on the lower side of the mounting plate 28 is rotated to disengage it from the two limiting posts 4, releasing the longitudinal limit on the sliding column 27. After the limiting rod 3 is unlocked, the spring 29 between the mounting plate 28 at the lower end of the front sliding column 27 and the top wall of the base 1 will release elastic potential energy, pushing the sliding column 27 to move upward, thereby driving the rubber seat 24 to move upward along the sliding hole 26, disengaging from the passive limit of the extrusion protrusion 23, and the reed can be directly removed from the reed placement groove 25.
