Description

Technical Field

[0001] This utility model relates to the field of clamping fixtures for shaping machines, and more specifically, it relates to a fixing fixture for a column shaping machine. Background Technology

[0002] In industrial production, column forming machines are key equipment for the precise shaping of various pipe fittings, and their performance directly affects the quality and efficiency of pipe fitting processing. Among them, the fixing fixture, as an important component of the column forming machine, undertakes the important task of stably clamping and reliably conveying the pipe fittings, and is the basic guarantee for ensuring the smooth progress of the shaping process.

[0003] Currently, pipe clamping devices on the market exhibit several shortcomings that urgently need to be addressed in practical applications. On one hand, existing pipe clamping devices lack adaptability to bent circular components. With the diversification of industrial products, pipe shapes are becoming increasingly complex, and the application of bent circular components is becoming more widespread. However, most existing clamping devices are designed for pipes with regular shapes and cannot effectively adapt to the special shape of bent circular components. During the clamping process, it is difficult to achieve precise positioning and stable clamping of the bent portion, resulting in poor clamping performance and even clamping failure.

[0004] On the other hand, existing pipe clamping devices suffer from serious stability and flexibility issues during the conveying process. Since pipes may exhibit varying degrees of bending, this bending leads to unstable clamping force when the pipes are fed into the forming machine. Insufficient clamping force causes the pipes to slip or deviate during conveying, affecting accuracy; excessive clamping force can damage the pipes, impacting their quality. Furthermore, the existing devices lack flexible direction following, failing to adjust the conveying direction in real-time according to the pipe's curvature. This misalignment can cause collisions or interference between the pipes and the forming machine's internal structure, further exacerbating deviation and resulting in unstable forming. Consequently, the dimensional accuracy and surface quality of the processed pipes fail to meet requirements, increasing the defect rate and production costs. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a column shaping machine fixing fixture that can clamp a circular part and follow the bending of the circular part.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The present invention is further configured as follows: it includes a housing, and the column shaping machine fixing fixture also includes a clamping and displacement mechanism; the clamping and displacement mechanism is disposed on the top of the housing; the clamping and displacement mechanism includes a bearing part, a sliding part, a displacement part, and a clamping part; the bearing part has a pair and is disposed on the top of the housing respectively; the sliding part is slidably disposed on the top of the bearing part, and there is a clearance fit between the sliding part and the bearing part; the displacement part has a pair and is slidably disposed on the top of the sliding part respectively; the clamping part has a pair and is slidably disposed on the top of the displacement part respectively; in the working state, the clamping part can be relatively close to each other and abut against the outer side of the circular part to be conveyed and processed.

[0007] By adopting the above technical solution, the problems of existing pipe clamping devices being unable to adapt to the clamping of bent circular parts, unstable clamping force during conveying, and lack of flexible following of the conveying direction are solved. The solution achieves the effect of ensuring stable clamping force and free following of the conveying direction during the clamping of bent circular parts, ensuring that the circular parts are stably conveyed into the forming machine for processing.

[0008] The present invention is further configured such that: the clamping displacement mechanism includes a first linear guide, a lead screw, and a linear actuator; the first linear guide has a pair and is respectively disposed on the top of the sliding part, and the pair of displacement parts are clearance-fitted; the lead screw has a pair and is respectively rotatably disposed on the side of the pair of first linear guides, and the pair of lead screws are respectively threadedly connected to the displacement parts; the linear actuator has a pair and is respectively disposed on the side of the first linear guide, and the output ends of the pair of first linear actuators are respectively connected to the input ends of the pair of lead screws.

[0009] The present invention is further configured such that: the clamping displacement mechanism also includes clamping cylinders; the clamping cylinders are a pair and are respectively disposed on the top of the displacement part, and the output ends of the pair of clamping cylinders are connected to the clamping part, so that when the clamping cylinders are activated, they can drive the clamping part to move in a relatively close state.

[0010] The present invention is further configured such that: the clamping displacement mechanism includes a setting plate, a telescopic cylinder and an abutting roller; the setting plate is installed on the top of the sliding part and is located between a pair of linear guide rails; the telescopic cylinder is installed on the top of the setting plate; the abutting roller is slidably disposed at the output end of the telescopic cylinder.

[0011] The present invention is further configured such that: the clamping displacement mechanism also includes a sliding plate; the sliding plate is slidably disposed at the output end of the telescopic cylinder, and the two ends of the sliding plate are rotatably connected to the abutting roller respectively.

[0012] The present invention is further configured such that: the abutting roller has a cylindrical structure, and in the working state, the outer side of the abutting part can rotate in abutting state with the end face of the circular part to be conveyed and processed.

[0013] In summary, this application includes at least one of the following beneficial technical effects: By incorporating a clamping displacement mechanism, during the conveying process of a circular part to be processed, the curvature of the circular part causes the displacement and sliding parts to move horizontally along the bearing part. This allows the circular part to be continuously clamped and conveyed even when the clamping part is holding a curved circular part, through horizontal movement. Attached Figure Description

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0017] Please see Figure 1-6 The present invention provides the following technical solution: Example 1: In order to solve the problems that existing pipe clamping devices cannot adapt to the clamping requirements of curved circular parts, and that the clamping force is unstable and the conveying direction lacks flexibility due to the bending of the pipe during the conveying process, which in turn causes the pipe to be easily deviated during conveying and the shaping process to be unstable.

[0018] The fixture for the column forming machine includes a housing 1 and a clamping and displacement mechanism 2. The clamping and displacement mechanism 2 is located on the top of the housing 1. The clamping and displacement mechanism 2 includes a bearing part 21, a sliding part 22, a displacement part 23, and a clamping part 24. There is a pair of bearing parts 21, which are respectively located on the top of the housing 1. The sliding part 22 is slidably located on the top of the bearing part 21, and there is a clearance fit between the sliding part 22 and the bearing part 21. There is a pair of displacement parts 23, which are respectively slidably located on the top of the sliding part 22. There is a pair of clamping parts 24, which are respectively slidably located on the top of the displacement part 23. In the working state, the clamping parts 24 can be relatively close to each other and abut against the outer side of the circular part to be conveyed and processed.

[0019] A pair of displacement portions 23 slide relatively close to each other on the top of the sliding portion 22 until the clamping portion 24 moves to the side of the circular part to be transported and processed. Then, the clamping portion 24 performs a clamping action on the outside of the circular part to be transported and processed. In this embodiment, the clamping portion 24 is preferably a rubber wheel, so that the normal transport of the circular part to be transported and processed is not affected when the clamping portion 24 clamps it. At the same time, the clamping portion 24 in this embodiment is also preferably an electric roller, capable of clamping and transporting the circular part to be transported and processed in an abutting state. During the transport of the circular part to be transported and processed, the curvature of the circular part will cause the displacement portion 23 and the sliding portion 22 to move horizontally along the bearing portion 21. This allows the clamping portion 24 to continuously clamp and transport the circular part even if it is a curved circular part, through horizontal movement.

[0020] See Figure 2 and Figure 3 The clamping displacement mechanism 2 also includes a first linear guide rail 25, a lead screw 26, and a linear actuator 27; the first linear guide rail 25 has a pair and is respectively disposed on the top of the sliding part 22, and the pair of displacement parts 23 are clearance-fitted; the lead screw 26 has a pair and is respectively rotatably disposed on the side of the pair of first linear guide rails 25, and the pair of lead screws 26 are respectively threadedly connected to the displacement parts 23; the linear actuator 27 has a pair and is respectively disposed on the side of the first linear guide rail 25, and the output ends of the pair of first linear actuators 27 are respectively connected to the input ends of the pair of lead screws 26.

[0021] In order to drive the displacement part 23 to move the clamping part 24 toward the circular part to be transported and processed, in this embodiment, the linear driver 27 is preferably a servo motor. When the linear driver 27 is started, it can drive the lead screw 26 to rotate. When the lead screw 26 rotates, it can drive the threaded displacement part 23 to move horizontally along the first linear guide rail 25.

[0022] See Figure 2The clamping displacement mechanism 2 also includes a clamping cylinder 28; the clamping cylinder 28 has a pair and is respectively disposed on the top of the displacement part 23, and the output ends of the pair of clamping cylinders 28 are connected to the clamping part 24. When the clamping cylinder 28 is activated, it can drive the clamping part 24 to move in a relatively close state.

[0023] In operation, when the clamping cylinder 28 is activated, it can drive a pair of clamping parts 24 connected to the clamping cylinder 28 to move closer to each other until the clamping parts 24 come into contact with the circular workpiece to be transported and processed and then stop moving.

[0024] See Figure 2 The clamping displacement mechanism 2 also includes a setting plate 29, a telescopic cylinder 291, and an abutting roller 292; the setting plate 29 is installed on the top of the sliding part 22 and is located between a pair of linear guide rails; the telescopic cylinder 291 is installed on the top of the setting plate 29; the abutting roller 292 is slidably disposed at the output end of the telescopic cylinder 291.

[0025] In this embodiment, when it is necessary to clamp the circular part to be conveyed and processed, the operator first places the circular part to be conveyed and processed on the top of the abutment roller 292. When the telescopic cylinder 291 is activated in the working state, it can drive the abutment roller 292 to move upward, thereby pushing the circular part to be conveyed and processed to both sides of the clamping part 24.

[0026] See Figure 2 The clamping displacement mechanism 2 also includes a sliding plate 293; the sliding plate 293 is slidably disposed at the output end of the telescopic cylinder 291, and the two ends of the sliding plate 293 are rotatably connected to the abutting roller 292 respectively. In the working state, when the telescopic cylinder 291 is started, it can drive the sliding plate 293 and the abutting roller 292 to move synchronously.

[0027] When the telescopic cylinder 291 is activated, it can drive the setting plate 29 and the abutting roller 292 to lift the round part to be transported and processed by water.

[0028] See Figure 2 The abutting roller 292 has a cylindrical structure. In the working state, the outer side of the abutting part can rotate and abut against the end face of the circular part to be conveyed and processed.

[0029] In this embodiment, the abutting roller 292 is preferably a rubber roller, which can abut against the circular part to be conveyed and processed.

[0030] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
