Description

TECHNICAL FIELD

[0001] The utility model relates to heat exchanger technical field, concretely is a kind of heat pipe clamping device for heat pipe heat exchanger production and processing. BACKGROUND

[0002] ‌Heat pipe heat exchanger is mainly composed of heat pipe, baffle and cold and hot fluid passage. The inside of heat pipe is in vacuum state and is full of working medium, and the two ends of heat pipe are evaporation end and condensation end respectively. In the production and processing process of heat pipe, including cutting, polishing and testing, etc., it needs to be clamped, and the stable clamping of heat pipe is the key technical link to ensure processing accuracy. The current mainstream clamping scheme of heat pipe is divided into two categories: profiling clamping structure and three-point pneumatic clamping structure.

[0003] The first type of profiling fixture adopts semicircular clamping block matched with the outer contour of pipe fitting, such as the clamping device for pipe fitting production with the announcement number CN220575201U, which realizes positioning by closing the symmetrical clamping block. Although this scheme can obtain higher clamping contact area, one clamping block can only correspond to one diameter of pipe fitting, and special clamping blocks need to be customized for different pipe diameters, which affects the operation efficiency.

[0004] The second type of three-point clamping device, such as the pneumatic clamp for pipe fitting with the announcement number CN211841096U, adopts three groups of independent air cylinders to drive clamping jaws to form an equilateral triangle clamping point. Compared with profiling fixture, this scheme can adapt to a wider range of pipe diameters through three-point positioning principle. However, in actual application, it is found that independent control of three sets of air cylinders leads to complex air circuit system, not only there is a risk of synchronization error, which affects the positioning and fixing accuracy, but also the three sets of air cylinders cause the number of components to be larger, which increases the failure rate and makes maintenance difficult. In addition, the existing three-point clamping device generally only clamps one position of the pipe fitting in the axial direction, and the clamping stability needs to be improved. If multiple positions are clamped, more air cylinders need to be added, and the structure is more complex. UTILITY MODEL CONTENTS

[0024] The detailed connection means is the technology known in the art, and the working principle and process are mainly introduced as follows:

[0025] According to the description attached Figures 1-4As can be seen, when this utility model is working, the drive assembly drives the horizontal plate 12, connecting plate 2, and V-shaped clamp 11 upwards, maximizing the hole formed between the V-shaped clamp 11 and the worktable 10. The V-shaped clamp 11 moves stably within the sliding opening 15. The operator inserts the heat pipe into the hole between the V-shaped clamp 11 and the worktable 10. The drive assembly then drives the horizontal plate 12, connecting plate 2, and V-shaped clamp 11 downwards, causing the inner wall of the V-shaped clamp 11 to simultaneously clamp and fix the heat pipe in conjunction with the worktable 10. Since the included angle of the V-shaped clamp 11 is 60 degrees and the opening faces downwards, it is tangent when in contact with the heat pipe. The angle between the two tangent points is 120 degrees. Therefore, with… The three contact points of the heat pipe are evenly distributed to ensure stable force during clamping and fixing. Since the V-shaped clamp 11 can move up and down, the size of the hole between it and the worktable 10 can be changed, thus making it suitable for clamping heat pipes of different diameters. All of them can achieve the purpose of three-point clamping and even distribution of force points. Under the premise of ensuring adaptability to multiple pipe diameters, only one set of drive components is used for driving. The overall structure is simple and convenient for maintenance. The V-shaped clamp 11 is limited by the sliding mouth 15, and the connecting plate 2 is limited by the cooperation of the slider 3 and the sliding groove 16. There are two sets of V-shaped clamps 11, which can achieve the purpose of stabilizing the clamping of heat pipes and improving the accuracy of subsequent processing.

[0026] The drive assembly includes a motor 1 and a threaded rod 14. The motor 1 is fixedly mounted at the bottom center of the support housing 13. The lower end of the threaded rod 14 is connected to the output end of the motor 1, and the upper end is rotatably connected to the bottom of the worktable 10. A threaded hole 4 is provided at the center of the horizontal plate 12, and the threaded rod 14 is screwed into the threaded hole 4. Of course, to ensure strength, a nut can be designed at the center of the horizontal plate 12, which is screwed into the threaded rod 14 to increase strength. During operation, the motor 1 drives the threaded rod 14 to rotate. The screwed connection between the threaded rod 14 and the horizontal plate 12, as well as the vertical sliding connection between the two sides of the connecting plate 2 through the slider 3 and the slide groove 16, allows the horizontal plate 12 to move vertically, thereby driving the connecting plate 2 and the V-shaped plate to move up and down. The drive structure is simple and convenient for maintenance.

[0027] The workbench 10 has an arc-shaped groove 9 along the front-back direction, which is an arc-shaped groove 9 along the axial direction of the heat pipe. After the heat pipe is placed on the workbench 10, it will stabilize in a centered state due to gravity, thus preventing the heat pipe from rolling when clamped by the V-shaped clamp 11.

[0028] The inner wall of the V-shaped clamp 11 is provided with an anti-slip rubber pad 5 to increase the friction between it and the heat pipe, ensure its stability, and reduce the wear on the heat pipe and the surface of the workbench 10 during loading and unloading.

[0029] A connecting rod 7 is fixedly installed between the inflection points of a pair of V-shaped clamps 11 to increase the overall stability of the V-shaped clamps 11. The tips of the V-shaped clamps 11 are designed with rounded corners 8 to eliminate potential safety hazards at the tips.

[0030] 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.
