Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to an automatic assembly fixture for flexible components. Background Technology

[0002] The property of an object to deform under stress and not return to its original shape after the force is removed is called flexibility, often used in mineralogy and metallurgy (as opposed to rigidity and tensile strength). For example, chlorite, which bends but does not stretch, is a mineral with significant flexibility. Aluminum, on the other hand, cannot return to its original shape once bent. The property of a mineral to deform under stress and return to its original state after the force is removed is called elasticity, as exemplified by mica, which bends and stretches, making it the mineral with the strongest elasticity.

[0003] When flexible components are clamped and subjected to force, the workpiece will deform when the pressure exceeds the deformation resistance. Furthermore, flexible components cannot return to their initial state after deformation. Therefore, when clamping flexible components, it is necessary to consider both the stability of the clamping and to avoid deformation. Traditional flexible component assembly fixtures will inevitably cause some deformation to the components when clamping hollow components. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic assembly fixture for flexible components. By cooperating with the limiting nut and the movable rod, the position of the movable plate can be easily restricted, which can both elastically and rigidly clamp the component. At the same time, the top plate drives the limiting post to support the component from the inside of the hollow component. With the clamping of the movable plate from the outside, the deformation of the component can be avoided when it is clamped, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic assembly fixture for flexible components, including a mounting base. Two sets of clamps are movably arranged on the back of the mounting base. An opening and closing component for moving the two sets of clamps is provided in the inner cavity of the mounting base. Movable plates are provided at the front and rear ends of the clamps on opposite sides. A movable rod is movably mounted on the outer side of the movable plate. A through hole is opened inside the clamp. The movable rod passes through the through hole and extends outward. A support spring is sleeved on the outer side of the movable rod. The support spring is located between the movable plate and the clamp. A threaded thread is opened at the end of the movable rod away from the movable plate and a limit nut is threadedly connected to it. A detachable top plate is also installed on the top of the clamp. A limit post is threadedly connected to the top plate. The bottom of the limit post extends downward.

[0006] Preferably, the opening and closing assembly includes a bidirectional screw that rotates within the inner cavity of the mounting base via a bearing. Two sets of connecting seats are threadedly connected to the outer side of the bidirectional screw via a threaded sleeve. The connecting seats penetrate the mounting base and are fixedly connected to the front end of the clamp. A worm gear is fixed at the center of the bidirectional screw. The inner cavity of the mounting base is also rotatably connected via a bearing to a worm that meshes with the worm gear. One end of the worm extends to the outer side of the mounting base and is fixed with a handle.

[0007] Preferably, one end of the movable rod is fixed to a fixed seat, the fixed seat is movably connected to the movable plate through the movable seat, one end of the support spring is fixed to the fixed seat, and the other end of the support spring is fixed to the clamp.

[0008] Preferably, the top of the clamp has a limiting groove, the bottom of the top plate is fixed with a limiting strip that slides in the limiting groove, a support base is fixed on the outer side of the top of the clamp, a traction screw is threaded onto the support base, and one end of the traction screw is rotatably connected to the top plate through a bearing.

[0009] Preferably, a storage groove is provided on the opposite side of the clamps, and the support spring is located in the inner cavity of the storage groove.

[0010] Preferably, the movable plate has an anti-slip vertical groove on one side facing each other, and the limiting post has an insertion hole at its top.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model supports the movable plate with clamps. The movable plate and clamps can clamp the workpiece from the outside when they are in different states. After the top plate is installed on the top of the clamps, the rotating limiting post penetrates into the inside of the workpiece. The top plate is then moved to facilitate support from the inside of the workpiece. The clamping of the movable plate and the stability of the component structure are ensured to prevent deformation caused by directly clamping the hollow workpiece.

[0013] 2. The present invention facilitates the storage of the support spring by setting up a storage slot, and makes it convenient for the movable plate to be unable to fit with the clamp after the support spring is compressed. Attached Figure Description

[0020] 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.

[0021] This utility model provides, for example Figures 1-5 The flexible component automatic assembly fixture shown includes a mounting base 1. Two sets of clamps 2 are movably arranged on the back of the mounting base 1. An opening and closing component 3 for moving the two sets of clamps 2 is arranged in the inner cavity of the mounting base 1. Movable plates 4 are arranged at the front and rear ends of the clamps 2 facing each other. Movable rods 5 are movably installed on the outer side of the movable plates 4. A through hole is opened in the inside of the clamps 2. The movable rods 5 pass through the through hole and extend outward. A support spring 6 is sleeved on the outer side of the movable rods 5. The support spring 6 is located between the movable plates 4 and the clamps 2. The end of the movable rods 5 away from the movable plates 4 is threaded and threadedly connected to a limit nut 7. A detachable top plate 8 is also installed on the top of the clamps 2. A limit post 9 is threadedly connected to the top plate 8. The bottom of the limit post 9 extends downward.

[0022] The movable plate 4 is supported by clamp 2. The movable plate 4 and clamp 2 can clamp the workpiece from the outside when they are in different states. After the top plate 8 is installed on the top of clamp 2, the limiting post 9 is rotated to penetrate into the inside of the workpiece. The top plate 8 is then moved to facilitate support from the inside of the workpiece. In conjunction with the clamping of the movable plate 4, the stability of the component structure is ensured to prevent deformation caused by directly clamping the hollow workpiece.

[0023] The opening and closing assembly 3 includes a bidirectional screw 31 that rotates within the inner cavity of the mounting base 1 via a bearing. Two sets of connecting seats 32 are threadedly connected to the outer side of the bidirectional screw 31 via a threaded sleeve. The connecting seats 32 pass through the mounting base 1 and are fixedly connected to the front end of the clamp 2. A worm gear 33 is fixed at the center of the bidirectional screw 31. The inner cavity of the mounting base 1 is also rotatably connected via a bearing to a worm 34 that meshes with the worm gear 33. One end of the worm 34 passes through the outer side of the mounting base 1 and is fixed with a handle 35. The worm 34 drives the worm gear 33 to rotate the bidirectional screw 31, which, in conjunction with the threaded sleeve, causes the two sets of connecting seats 32 to move towards each other. This, in turn, moves the clamp 2, which not only facilitates the clamping of the workpiece but also moves the movable plate 4 and the top plate 8.

[0024] One end of the movable rod 5 is fixed to a fixed seat 10. The fixed seat 10 is movably connected to the movable plate 4 through the movable seat. One end of the support spring 6 is fixed to the fixed seat 10, and the other end of the support spring 6 is fixed to the clamp 2. Through the cooperation of the fixed seat 10 and the movable seat, the movable rod 5 and the movable plate 4 are movably connected, which allows the movable plate 4 to be flipped back and forth, making it convenient to clamp workpieces of different shapes.

[0025] The clamp 2 has a limiting groove 11 on its top. The bottom of the top plate 8 is fixed with a limiting strip 12 that slides in the limiting groove 11. A support base 13 is fixed on the outer side of the top of the clamp 2. A traction screw 14 is threaded onto the support base 13. One end of the traction screw 14 is rotatably connected to the top plate 8 through a bearing. The top plate 8 can be easily installed on the top of the clamp 2 by sliding the limiting strip 12 in the limiting groove 11. Then, the position of the top plate 8 can be moved and adjusted by the cooperation of the traction screw 14 and the support base 13.

[0026] A storage groove 15 is provided on one side of the clamp 2 facing each other. The support spring 6 is located in the inner cavity of the storage groove 15. The storage groove 15 facilitates the storage of the support spring 6 and prevents the movable plate 4 from fitting with the clamp 2 after the support spring 6 is compressed.

[0027] The movable plate 4 has an anti-slip vertical groove on one side facing each other, and the top of the limiting post 9 has an insertion hole. The anti-slip vertical groove increases the friction between the movable plate 4 and the workpiece, preventing the workpiece from sliding when the movable plate 4 is used to clamp the workpiece.

[0028] In practical use, the top plate 8 is slidably installed on the top of the clamp 2 in the limiting groove 11 via the limiting strip 12. At the same time, the traction screw 14 is threaded through the support seat 13. The hollow workpiece is placed inside the clamp 2. The worm gear 34 is rotated, and the worm wheel 33 drives the bidirectional screw 31, causing the bidirectional screw 31 to drive the connecting seat 32 to move in opposite directions through the threaded sleeve. At the same time, the connecting seat 32 drives the clamp 2 to move. The workpiece can be clamped using the movable plate 4, and supported by the support spring 6. Alternatively, the movable rod 5 can be pulled using the limiting nut 7, so that the movable plate 4 fits against the clamp 2, compressing the support spring 6 into the receiving groove 15. Then, the traction screw 14 is rotated to move the top plate 8. Then, the limiting post 9 is rotated, and the limiting post 9 is inserted into the cavity of the workpiece, so that the limiting post 9 supports the workpiece from the inside, working with the movable plate 4 to maintain the stability of the hollow workpiece structure.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
