Description

Technical Field

[0001] This utility model relates to the technical field of copper tube processing equipment, and in particular to a clamping device for copper tube processing. Background Technology

[0002] Copper tubes are widely used in refrigeration, heating, power, and machinery manufacturing due to their excellent thermal conductivity, corrosion resistance, and plasticity. During copper tube processing, such as cutting, bending, flaring, or polishing, they typically need to be stably clamped onto processing equipment. The reliability of the clamping device directly affects processing accuracy, production efficiency, and product quality.

[0003] Currently, existing copper tube clamping methods have the following drawbacks:

[0004] This can easily lead to pipe deformation: Traditional three-jaw chucks or pneumatic clamps mainly clamp copper pipes radially from the outside. Since copper pipes are thin-walled components with relatively poor rigidity, excessive clamping force can easily cause the pipe to be flattened or deformed into an ellipse. This deformation is often irreversible and will lead to product scrap.

[0005] Poor centering accuracy: For processes that require rotational machining (such as grinding or polishing the outer wall of the tube), ordinary fixtures cannot ensure that the rotation center of the copper tube is strictly aligned with the spindle center, which can easily cause radial runout, affecting the consistency of machining and surface quality.

[0006] Adaptability and efficiency issues: Traditional clamps require frequent adjustments or replacements of clamping blocks for copper tubes of different lengths and diameters, making operation cumbersome and time-consuming, and failing to meet the requirements of modern production lines for flexibility and high efficiency. Furthermore, clamps lacking effective internal support often result in operators being hesitant to apply sufficient clamping force to prevent flattening, potentially causing the copper tube to slip or loosen during processing, posing a safety hazard.

[0007] Inconvenient clamping: Although some existing pin-type clamping devices can solve some of the centering problems, they require both ends to be aligned simultaneously during clamping and disassembly, which is not convenient to operate, and they usually do not have the function of flexibly adjusting the angle during clamping.

[0009] To achieve the above objectives, this utility model adopts the following technical solution:

The locking ring is inserted and mounted on the fixed vertical plate.

[0011] A rotating handle is provided on the outer end face of the rotating rod on the fixed plate facing away from the middle of the base plate.

[0012] The inner diameter support assembly includes a connecting rod and several support rods installed on the end face of the frustum-shaped cone rod.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] like Figures 1 to 3 As shown, a clamping device for copper tube processing includes a base plate 1, a fixed vertical plate 2, a movable vertical plate 3, a rotating rod 4, a frustum-shaped cone rod 5, an inner diameter support assembly 6, a spline ridge 7, a locking ring 8, a spline hole 9, a rotating handle 11, a lead screw 12, a drive motor 13, a moving seat 14, a limiting rod 15, and a plug-in post 16.

[0029] The base plate 1 serves as the foundation platform for the entire device.

[0030] A fixed vertical plate 2 and a movable vertical plate 3 are installed on the upper surface of the base plate 1. The fixed vertical plate 2 and the movable vertical plate 3 constitute two fulcrums for clamping.

[0031] The movable upright plate 3 is connected to a movable drive mechanism. The movable drive mechanism includes a groove on the base plate 1 and a lead screw 12 is provided in the groove. The lead screw 12 is connected to a drive motor 13. A movable seat 14 is threaded on the lead screw 12 and fixed to the bottom of the movable upright plate 3.

[0032] A limiting rod 15 is provided in the groove, and the limiting rod 15 is movably inserted on the movable seat 14.

[0033] The system includes a lead screw 12, a drive motor 13, a moving base 14, and a limit rod 14 to ensure smooth movement and prevent deviation.

[0034] Used to drive the movable upright plate 3 closer to or further away from the fixed upright plate 2 to accommodate copper pipes 10 of different lengths.

[0035] Both the fixed upright plate 2 and the movable upright plate 3 are rotatably mounted with rotating rods 4. One end of the rotating rod 4 facing the middle of the base plate 1 is provided with a frustum-shaped cone rod 5, and the copper tube 10 to be processed is clamped between the two frustum-shaped cone rods 5.

[0036] The frustum-shaped cone rod 5 is the core clamping component. Utilizing its cone-shaped surface, it can achieve automatic centering and stable outer wall clamping when clamping the end of the copper tube 10, and can be adapted to copper tubes 10 of different diameters.

[0037] The outer wall of the frustum-shaped cone rod 5 is provided with a rubber anti-slip protective pad to increase friction, prevent slippage during clamping, and protect the surface of the copper tube 10 from being scratched.

[0038] An inner diameter support assembly 6 is installed on the end face of the frustum-shaped cone rod 5. The inner diameter support assembly 6 includes a connecting rod 61 and several support rods 62 installed on the end face of the frustum-shaped cone rod 5. A baffle 63 is provided on one end face of the support rod 62. Threaded rods 64 are provided on the end faces of the connecting rod 61 and the baffle 63. The threaded rods 64 can be detached and installed in sequence. An inner support ring 65 passes through the support rod 62. The outer diameter of the inner support ring 65 is the same as the inner diameter of the copper tube 10.

[0039] The inner diameter support assembly 6 provides support from inside the copper tube 10 to prevent the copper tube 10 from being flattened or deformed during processing. The support ring 65 can avoid the processing position of the copper tube 10. By selecting an appropriate number of support rods 62 as needed, the length of the inner support can be controlled without interfering with the processing.

[0040] On the fixed upright plate 2, the outer wall of the rotating rod 4 facing away from the middle of the base plate 1 has several spline ridges 7 around its circumference, and a locking ring 8 passes through the spline ridges 7. The inner ring of the locking ring 8 has a spline hole 9 that matches the spline ridge 7. The locking ring 8 is inserted and installed on the fixed upright plate 2.

[0041] The locking ring 8 has several plug-in pins 16 on its end face and several plug-in holes on its fixed plate 2. The plug-in pins 16 are inserted into the corresponding plug-in holes.

[0042] A rotating handle 11 is provided on the outer end face of the rotating rod 4 on the fixed upright plate 2 facing away from the middle of the base plate 1.

[0043] The spline connection and locking ring 8 are key to achieving the rotation function. The rotating rod 4 on one side of the fixed plate 2 engages with the locking ring 8, which has a splined hole 9, via the splined edge 7. When the locking ring 8 disengages from the fixed plate 2, the rotating rod 4 can rotate freely (e.g., manually driven by the rotating handle 11); when the locking ring 8 is fixed to the fixed plate 2 via a structure such as the plug-in post 16, the rotating rod 4 is locked and cannot rotate. This design allows the rotating rod 4 to rotate when clamping the copper tube 10, making it easier to screw the frustum-shaped cone rod 5 into the end of the copper tube 10; and locks the rotating rod 2 during machining to prevent its rotation from affecting machining accuracy. The rotation angle of the copper tube 10 can also be adjusted for machining positioning.

[0044] The movable upright plate 3 of this utility model can be adjusted to accommodate copper tubes 10 of different lengths. The frustum-shaped cone rod 5 and the inner diameter support component 6 can be adapted to copper tubes 10 with different inner diameters. The frustum-shaped cone rod 5 can automatically center itself, and combined with the rotatable rotating rod 4, it makes the clamping and disassembly of the copper tube 10 simple and secure. The inner diameter support component 6 effectively prevents the elliptical deformation of the copper tube 10 during clamping and processing. Through a simple locking ring operation, it is possible to switch between the two modes of "free rotation" (for easy clamping) and "fixed locking" (for easy processing).

[0045] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
