Description

Technical Field

[0001] This utility model relates to the field of thin-walled part processing technology, specifically to a clamping device for thin-walled part processing. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for construction or inspection. It is also called a clamp. In a broader sense, any device used to quickly, conveniently and safely install a workpiece in any step of the process can be called a fixture.

[0003] For example, Chinese Patent (CN214814940U) relates to a chuck for clamping thin-walled pipe fittings, including a chuck body with a circular disc surface, and a cylindrical hole perpendicular to the disc surface of the chuck body, the cylindrical hole being located at the center of the chuck body. Multiple clamping arms movable towards the cylindrical hole are provided on the outer side of the chuck body, and these clamping arms are arranged at equal intervals along the outer edge of the chuck body. The key feature is that a clamping end is provided on the inner side of each clamping arm, and a clamping block is provided on the clamping end. The inner arc segment of the clamping block has an inner arc opening. The number of inner arc openings can be increased according to the size requirements of the thin-walled pipe fitting. The two sides of the inner arc opening are clamping portions with smooth, arc-shaped end faces, which can increase the contact area with the outer wall of the pipe fitting, providing sufficient clamping force for processing the thin-walled pipe fitting, making it less likely for the processed part to slip, detach, or deviate. Simultaneously, the inner arc openings are evenly distributed around the cylindrical hole, ensuring uniform force during processing of the thin-walled pipe fitting, avoiding deformation or damage to the processed part due to excessive clamping force.

[0004] The above-mentioned solution uses clamping blocks to clamp the pipe on the outside. The clamping blocks may cause scratches or indentations on the surface of the pipe during the clamping process, affecting the appearance and performance of the pipe. External clamping may lead to uneven distribution of clamping force, thereby affecting the stability and accuracy of the pipe. In order to solve the above problems, a clamping device for thin-walled parts processing is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, a clamping device for processing thin-walled parts is provided. This device solves the problems of the current method of using clamping blocks to clamp the pipe on the outside, which may cause scratches or indentations on the surface of the pipe during the clamping process, affecting the appearance and performance of the pipe. External clamping may also lead to uneven distribution of clamping force, thus affecting the stability and accuracy of the pipe.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a clamping device for processing thin-walled parts, comprising a base plate, a moving motor fixedly installed on the left side of the upper surface of the base plate, a rotating support fixedly connected to the right side of the upper surface of the base plate, a bidirectional lead screw fixedly connected to the output end of the moving motor, the threads of the left and right ends of the bidirectional lead screw having opposite directions, the right end of the bidirectional lead screw being rotatably connected to the left side of the rotating support, threaded seats threadedly connected to both sides of the outer surface of the bidirectional lead screw, moving plates fixedly connected to the outer sides of both threaded seats, moving guide rails fixedly connected to the upper surface of the base plate and the front and rear sides of the bidirectional lead screw, a snap-fit ​​groove adapted to the moving guide rail being opened at the lower end of both moving plates, and an inner support assembly being provided at the upper inner side of both moving plates.

[0007] Preferably, the inner support assembly includes a fixed plate, which is fixedly connected to the inner side of the movable plate. At least six sets of limiting grooves are provided on the side of the fixed plate away from the movable plate, and limiting sliders are slidably connected inside the limiting grooves.

[0008] Preferably, a support rod is fixedly connected to the side of the limiting slider away from the fixed plate, and a rubber pad is fixedly connected to the outside of the support rod.

[0009] Preferably, the inner support assembly further includes an adjusting motor, which is fixedly connected to the side of the moving plate away from the fixed plate. The output end of the adjusting motor passes through the fixed plate and is fixedly connected to a threaded rod, and the surface of the threaded rod is threaded with a threaded post.

[0010] Preferably, a fixing plate corresponding to the number of limiting grooves is fixedly connected to the outer surface of the threaded column, and connecting ears are fixedly connected to both the left and right ends of the outer side of the fixing plate.

[0011] Preferably, both connecting ears are rotatably connected to an inner support rod, and the end of the inner support rod away from the connecting ear is rotatably connected to the inner side of the support rod via a pivot.

[0012] Preferably, both ends of the two movable plates near the adjusting motor are fixedly connected with reinforcing plates.

[0013] Compared with the prior art, the advantages of this utility model are as follows: This utility model sets an internal support component to tighten the pipe inside the thin-walled pipe. Since the tightening is carried out inside the pipe, there is almost no direct contact with the external surface, thereby reducing the risk of surface damage. It can apply clamping force evenly inside the pipe, which can usually provide a more stable and uniform clamping effect. In addition, the internal support component can be adjusted to adapt to pipes with different inner diameters, which usually reduces the complexity of the clamping device. The use of a moving motor to drive the bidirectional lead screw to rotate can realize the adjustment of the distance between the two internal support components, which can adapt to pipes of different lengths, making the clamping component versatile and flexible.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Reference Figure 1-3 As shown, a clamping device for processing thin-walled parts includes a base plate 1. A moving motor 3 is fixedly installed on the left side of the upper surface of the base plate 1, and a rotating support 5 is fixedly connected to the right side of the upper surface of the base plate 1. A bidirectional lead screw 4 is fixedly connected to the output end of the moving motor 3. The design of the bidirectional lead screw 4 allows the moving plates 7 on both sides to move simultaneously towards the center or outward during the driving process, improving the efficiency of the clamping operation. The threads at the left and right ends of the bidirectional lead screw 4 have opposite directions. The right end of the bidirectional lead screw 4 is rotatably connected to the left side of the rotating support 5. Threaded seats 6 are threadedly connected to both sides of the outer surface of the bidirectional lead screw 4. Moving plates 7 are fixedly connected to the outer sides of both threaded seats 6. Moving guide rails 2 are fixedly connected to the upper surface of the base plate 1 and the front and rear sides of the bidirectional lead screw 4. The lower ends of both moving plates 7 are provided with snap-fit ​​grooves 8 that are adapted to the moving guide rails 2. The tight fit between the snap-fit ​​grooves 8 and the moving guide rails 2 makes the moving plates 7 move more smoothly, reduces friction and wear, and extends the service life of the device. Inner support components 9 are provided on the upper inner sides of both moving plates 7.

[0021] Specifically, the inner support component 9 includes a fixed plate 901, which is fixedly connected to the inner side of the movable plate 7. At least six sets of limiting grooves 908 are provided on the side of the fixed plate 901 away from the movable plate 7, and limiting sliders 909 are slidably connected inside the limiting grooves 908.

[0022] Specifically, a support rod 910 is fixedly connected to the side of the limit slider 909 away from the fixed plate 901, and a rubber pad 911 is fixedly connected to the outside of the support rod 910. The rubber pad 911 on the outside of the support rod 910 can effectively protect the inner wall of the thin-walled pipe and avoid scratches or damage during clamping, thus ensuring the quality of the workpiece.

[0023] Specifically, the inner support assembly 9 also includes an adjustment motor 902, which is fixedly connected to the side of the moving plate 7 away from the fixed plate 901. The output end of the adjustment motor 902 passes through the fixed plate 901 and is fixedly connected to a threaded rod 903. A threaded post 904 is threadedly connected to the surface of the threaded rod 903. By driving the threaded rod 903 and the threaded post 904 through the adjustment motor 902, the inner support connecting rod 907 can be automatically adjusted according to the size of the thin-walled pipe, realizing adaptive clamping of pipes of different diameters.

[0024] Specifically, the outer surface of the threaded column 904 is fixedly connected with a fixing plate 905 corresponding to the number of limiting grooves 908, and the left and right ends of the fixing plate 905 are fixedly connected with connecting ears 906.

[0025] Specifically, both connecting ears 906 are rotatably connected to an inner support rod 907. The end of the inner support rod 907 away from the connecting ear 906 is rotatably connected to the inside of the support rod 910 via a pivot. Through the design of the connecting ear 906 and the fixing plate 905, the inner support rod 907 can ensure that the thin-walled pipe is subjected to a uniformly distributed force during the tightening process, reducing the risk of deformation caused by uneven force.

[0026] Specifically, reinforcing plates 10 are fixedly connected to both ends of the two movable plates 7 near the adjusting motor 902. The addition of reinforcing plates 10 effectively enhances the overall structural strength of the movable plates 7, so that the device can remain stable when clamping thin-walled pipes with large diameters or heavy weights, and is not prone to deformation or damage.

[0027] Working principle: When clamping thin-walled pipe fittings, one end of the thin-walled pipe fitting is first sleeved on the outside of the inner support assembly 9 on one side. The adjusting motor 902 drives the threaded rod 903 to rotate. Under the threaded engagement, the threaded column 904 moves away from the adjusting motor 902. The movement of the threaded column 904 causes the inner support connecting rod 907 to change from an inclined state to a vertical state, thereby providing support on the inside of the thin-walled pipe fitting. After one end of the thin-walled pipe fitting is tightened, the moving motor 3 drives the double-acting screw 4 to rotate. Under the threaded engagement, the two moving plates 7 move relative to each other, thereby allowing the inner support assembly 9 at the other end to enter the interior of the thin-walled pipe fitting. Similarly, the inner support assembly 9 at the other end opens to tighten the thin-walled pipe fitting.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
